FUNDAMENTALS OF THE INVENTION Field read invention
The present invention relates to a clothes washing machine, and more particularly to a clothes washing machine capable of generating steam, for utilizing the steam, and a method of controlling the same. Discussion of related technique
A washing machine can include a washer and a dryer. Here, the washer means an apparatus for separating contaminants from garments for washing, using washing water and detergent. That is, the garment washing machine can separate contaminants from the garment to be washed by using chemical action of detergent dissolved in wash water and mechanical action of wash water or mechanical action by actuation of an internal tub (drum).
The dryer means an apparatus for drying clothes for washing. That is, the dryer dries laundry garments by providing hot dry air to laundry garments.
Another garment washing machine may include a washer and dryer combination capable of not only drying but also washing. Similar to the washing machine mentioned above, the washer and dryer combination can perform washing using detergent wash water. In this regard, the combination washer and dryer can be referred to as a garment washing machine.
One type of garment washing machine is a horizontal axis garment washing machine in which a drum receiving laundry garments is driven with respect to a horizontal axis to carry out washing. In such a horizontal axis garment washing machine, mechanical energy is applied to laundry garments by driving the drum to separate contaminants from the laundry garment.
The washing environment of the horizontal axis laundry machine can be an environment in which laundry is partially immersed in water. Consequently, most mechanical actions for washing garments to be washed in the horizontal axis garment washing machine may include friction between garment laundry, friction between laundry garment and tarpbor, impact force applied to laundry garment , etc.
Naturally, in this case, washing can be carried out through the chemical action of a detergent.
Another type of garment washing machine is a vertical axis garment washing machine in which an inner tub receiving garments for washing rotates relative to a vertical axis, or a pulsator installed in the inner tub rotates, to carry out washing. In such a vertical axis washing machine, mechanical energy is applied to washing clothes by driving the inner bowl or pulsator to separate contaminants from the washing clothes, as in the aforementioned horizontal axis washing machine.
The wash environment of the vertical axis garment washing machine can be an environment in which laundry garments are partially immersed in water. Consequently, most mechanical actions for washing garments to be laundered in the vertical axis garment washing machine may include friction between the garment to be laundered and the flow of water, impact force applied to the garment to be laundered, etc. Naturally, in this case, washing can also be carried out through the chemical action of a detergent.
Thus, the vertical axis garment washing machine and the horizontal axis garment washing machine have a big difference in terms of the amount of washing water used in the washing and the washing mechanism.
Despite such a difference, both the horizontal axis garment washing machine and the vertical axis garment washing machine may include a wash heater to heat wash water. Wash water heating can be performed for promoted detergent stivation for improved washing effects and for improved high temperature sterilization effects. Therefore, generally, the wash water temperature can be increased to ! a p-temperature is determined by activating the wash heater. That is, generally washing effects can be improved by increasing the temperature of the washing water.
Recently, a garment washing machine, in which steam is supplied to create a high temperature washing environment while reducing energy consumption, has come into wide use. In such a garment washing machine, vaioor is generated and fed to a drum in order to create a warm and humid washing environment for enhanced washing effects. This garment washing machine can achieve enhanced wash effects through a steam wash cycle using steam in addition to water wash.
In such a garment washing machine, however, there are increased costs and control difficulty because a separate steam generator needs to be | employee. In detail, the steam generator includes a steam heater for generating steam, separately from a general wash heater. For this reason, use of a garment washing machine, which employs a wash heater while excluding a separate steam generator, has been proposed. I ■ .
Steam can be generated by heating water to or above the boiling point of water. In this regard, a laundry garment machine equipped with a separate steam generator may be a laundry garment machine in which water is heated to or above the boiling point thereof to generate steam, and the generated steam is used for washing. Steam can also be generated by heating water to a temperature lower than the boiling point of water. In this regard, a garment washing machine, which employs a wash heater while excluding a separate steam generator, may be a garment washing machine in which water is heated to a temperature lower than the boiling point of this, to generate steam, and the steam generated is used for washing.
In the garment washing machine, which generates steam, using the washing heater I, steam is generated inside the tub. That is, steam can be generated over a relatively large space. Therefore, generally, steam can be generated by heating water to a temperature lower than the boiling point of water by the wash heater.
In the garment washing machine, which generates steam using the washing heater, steam is mainly used during water washing due to structural restriction.
Steam can be used to achieve enhanced washing effects in water washing. Steam can also be used to remove creases from washing garments. In particular, in a washing machine such as a dryer, a crease cycle can be provided.
In a dryer, steam can mainly be used to crease clothes for washing, eg to remove creases or odor, rather than enhancing washing effects.
Hereinafter, a conventional general laundry washing machine will be described with reference to FIGs. 1 and 2.
The garment washing machine may include a box 10 to form an appearance of the garment washing machine, and a tub 20 installed in the box 10. The cell 20 can be configured to receive wash water.
The tub 20 can be provided with a wash heater 60 to heat wash water. Due to gravity, the level of wash water water supplied to the tub 20 can be gradually increased from a bottom surface of the tub 20. Consequently, the wash heater 60 can be disposed at a lower portion of the tub 20.
A drum 30 is disposed within the tub 20. The drum 30 is rotatably installed in the tub 20. Laundry clothes are received in the drum 30. The drum 30 can be driven by a drive unit 71-72. By activating the drum 30, washing can be carried out.
The drive unit may include a motor 71. Motor drive 71 can be directly co-inverted into drum drive 30. The structure is generally referred to as a "direct connection type motor structure". Naturally, rotation of motor 71 can be converted into drive of drum 30 via a pulley 72, as illustrated in the figures.
Due to the drive of the drum 30, etc., vibration can be transmitted to the bowl 20. For this purpose, the bowl 20 can be supported relative to the housing 10 by dampers 21.
A door 40 can be provided at the front of the drum 30. A gasket 50 can be provided at the rear of the door 40. The gasket 50 can be connected to the box 10 and the riser 20. Consequently, the front side of the tub 20 can be elastically supported relative to box 10 by gasket 50.
To carry out the wash wash water must first be supplied. To this end, a water supply unit 80 is provided to supply washing water from an external water supply source to the garment washing machine.
The water supply unit 80 may include a water supply valve 81, which is selectively open or closed, and a wash water passage 82. The wash water passage 82 may be connected with a detergent box 83 to receive detergent. Detergent box 83 can be supplied to a supply passage 84.
Wash water and detergent supplied through the supply passage 84 can be mainly supplied to the interior of the drum 30.
As illustrated in FIG. 2, a plurality of through holes 31 is provided in the drum 30. The interior of the drum 30 can communicate with the interior 5 of the trough 20 through the through holes 31.
A heater mounting recess 22 may be formed at a lower portion of the bowl 20. The heater mounting recess 22 may be provided at a lower portion of the bowl 20. Since the wash heater 60 is mounted in the bowl 20. fitting the heater 22, it can remain immersed in water even at a lower wash water level.
The heater mounting recess 22 can be connected to a drain passage 23. Consequently, wash water in the tub 20 can drain out of the garment machine for washing through the heater mounting recess 22 and the drain passage 23 .
As mentioned above, generally, steam generation using the wash heater 60 requires water wash as a pre-condition of it. This can also be seen from the different features of the laundry machine illustrated in FIGs. 1 and 2.
In detail, washing water and washing detergent are supplied 20 to the inside of the drum 30. That is, when the water supply is carried out, the washing water and the supplied detergent wet laundry clothes received in the drum 30. The washing water and detergent are partially collected in bowl 20, starting from the bottom of bowl 20.
As the water supply continues, the wash water level is gradually increased. Water supply continues until the wash water level reaches a pre-determined water level.
In particular, the predetermined water level in the horizontal axis washing machine is relatively lower than that of the vertical axis washing machine. In other words, in the horizontal axis laundry washing machine, washing is carried out in an environment in which the laundry is partially immersed in water. Therefore, the structure in which freshwater and detergent are directly supplied to garments for washing can be general.
In order to generate steam using the wash heater 35 consequently there may be a problem that water must always be supplied through the interior of the drum. That is, there can be a problem that the supply of wash water inevitably involves wetting at least a portion of the laundry received in the drum.
For this reason, it is dificuldac to use steam in a variety of ways because the use of steam requires water washing as a pre-condition of it.
In detail, there are many problems with using steam just to remove creases. This is because laundry garments having creases removed have a very high moisture content due to the aforementioned structural problem and as such a separate drying procedure would be necessary.
Meanwhile, the level of crease removal in conventional laundry washing machines is around a level of simply providing moisture to laundry garments using steam. That is, removing creases in conventional garment washing machines only involves tipping over the drum in order to provide steam evenly to all laundry garments. Therefore, it is necessary to provide a scheme capable of deriving optimal relationships between steam generation and supply structure, steam temperature, and drum drive, to allow more efficient crease removal execution.
Furthermore, it is necessary to provide a laundry washing machine capable of performing crease removal while reducing a subsequent drying procedure as much as possible. That is, it is necessary to provide a washing machine capable of performing a crease removal performance, allowing the use of clothes immediately after removing the creases from the same without the need for drying through a dryer or natural drying.

Thus, the secure wash water passage is preferably used if the garment to be washed is not to be wetted. Furthermore, the second wash water passage is preferably configured to supply fresh water to the tub, i.e. without going through a detergent box or the like. Preferably fresh water is used for the steaming operation, as steam is generated using fresh water supplied through the second wash water passage, i.e. without detergent. Also for the cooling operation, preferably fresh water is used, supplied through the second wash water passage. By these means, deposition of detergent in the wash heater during steam generation or during a cooling operation can be avoided, thereby increasing the operability of the washing machine.
The laundry machine may additionally include a first water supply valve for opening or closing the first wash water passage, and a second water supply valve for opening or closing the second wash water passage. The first water supply valve II and the second water supply valve may be separate from each other. In other words, the first and second wash water passages can supply wash water at different positions, respectively. Naturally, the first and second wash water passages can supply wash water from the same external water supply source. Alternatively, a multi-way valve or a directional control valve can be used, as well as a three-way valve.
The second wash water passage may be a passage formed between the tub and the drum to supply wash water to the tub.

The steam cycle may include a steam wash cycle including a steaming operation and a main washing operation to perform water washing by the washing water, and a crease cycle including a second steaming operation at the same time when excluding the main wash operation, to remove creases from garments for steam washing. In other words, the plurality of wash cycles may include cycles, in which water wash is applied without using steam, and/or cycles, in which water and steam wash supply is performed, and/or cycles , in which the laundry is not wetted by the washing water.
The controller can perform a control operation to supply wash water into the vat through the second wash water passage, or through the second water supply valve, when the crease cycle is selected. I
The controller may perform a control operation to supply wash water to an interior of the drum through the first wash water passage, or through the first water supply valve, to perform the steam wash cycle steam operation operation. . The controller can perform a control operation to supply the wash water to the inside of the vat through. from the second wash water passage, or through the second water supply valve, for carrying out the crease cycle steaming operation. That is, it may be possible to change the wash water supply passage according to the selected cycle.
The steaming operation can be an operation of supplying steam to an interior of the drum. This can be achieved by operating the wash heater at a predetermined water level for steam generation which is lower than a drum bottom. That is, the steaming operation can be an operation of activating the wash heater while preventing the garment to be washed in the drum from coming into contact with the wash water, that is, under the condition that the garment to be washed do not come into contact with wash water. Generally, when using the second wash water pass, for example for a cooling or spraying operation, water is preferably supplied to a bottom of the drum at most.
The predetermined water level for steam generation can be a water level at which the wash heater is completely immersed in water.
The actuation of the wash heater in the steaming operation can be carried out continuously for a variable time, and a maximum allowable value of the variable time can be predetermined, taking into account a wash heater capacity and a quantity of wash water in the water level for steam generation.
The steaming operation may include a temperature control operation of continuously turning on the wash heater until a heating temperature of the wash heater reaches a predetermined temperature, and a time control operation of continuously turning on the wash heater by a predetermined time after completion of the temperature control operation.

The controller can carry out a control operation to supply the wash water to the inside of the vat! to a predetermined water level for water replenishment through the second wash water passage, or through the second water supply valve, after completion of the crease clearing operation.
The water level for water replenishment may be higher than a water level for steam generation, and/or lower than a drum bottom.
The controller can control the drum to perform the drive operation and tip over in the vaporizing operation.
In another aspect of the present invention, a method is provided for controlling a garment washing machine in accordance with any of the above-described examples to perform a crease strip cycle for removing or reducing creases formed in the laundry garment by providing creases. steam to wash clothes. The method may include a steam water supply operation of supplying wash water from an external water supply source to an interior of a vat to a water level for steam generation while preventing the washing water is passed through a drum, a washing water heating vaporization operation by activating a washing heater provided in the tub, thus generating steam from the washing water at the water level to generate steam, and a crease operation to remove creases from laundry garments. The wash heater is preferably arranged at the end of the tank, i.e. on the inside or outside of it. The method may further include a cycle selection operation of selecting one of a plurality of wash cycles, wherein the steam water supply operation is performed when the crease cycle is selected in the cycle selection operation. Further, the crease removal operation may include performing alternately, after performing the steaming operation, a tipping drive operation to tip the garment to wash into the drum in accordance with drum rotation and a centrifugal drive operation to rotate the garment to wash inside the drum in close contact with an inner surface of the drum, along with the drum, in accordance with high-speed rotation of the drum. Preferably, the tipping drive operation and the spin drive operation are performed repeatedly. Tipping drive can be set as drum drive causing garment 5 to wash into drum to fall out according to drum rotation. Spin drive can be defined as drum drive causing garments to wash inside the drum to rotate with the drum while in close contact with an inner surface of the drum in accordance with high speed rotation of the drum. In this regard, drum rotation speed during centrifugation drive should be higher than drum rotation speed during tipping drive.
The plurality of lay cycles may include a water wash run water wash cycle by supplying wash water to a water level for main wash. The water wash cycle may include an executable heating cycle in which a heating operation is performed after supplying the wash water to the water level for the main wash, and a cycle that excludes heating in which the operation of heating is excluded.
The water level for the main wash can always be higher than the water level for steam generation, irrespective of a garment quantity to be washed and the water wash cycle selection.
The supply of wash water to the main wash water level can be carried out in such a way that wash water is supplied from the external water supply source to an interior of the drum through a detergent box.
The supply of wash water to the water level for steam generation can be carried out through a rear water supply port provided in a portion of the rear top of the tub.
The actuation of the wash heater in the steaming operation 30 can be carried out continuously for a variable time, and a maximum allowable value of the variable time can be predetermined, taking into account a wash heater capacity and a quantity of wash water at the water level for steam generation.
The steaming operation may include a temperature control operation to continuously turn on the wash heater until a heating temperature of the wash heater reaches a predetermined temperature, and a time control operation to continuously turn on the wash heater. for a predetermined time after completion of the temperature control operation. The preset time of the time control operation can be a maximum allowable value. That is, the predetermined time can be a maximum allowable time.
Consequently, as the time required for the temperature control operation increases, the time required for the time control operation can be shortened because the maximum allowable value of the vaporizing operation is predetermined.
The pre-set temperature in the temperature control operation can be 93 to 97°C. In detail, the predetermined temperature can be 95°C. The crease removal operation is performed for a predetermined time.
In the crease removal operation, a drum drive cycle including the tipping drive operation and the spin drive operation can be repeated several times.

DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the attached figures.
First, an example of a laundry washing machine applicable to an embodiment of the present invention will be described in detail with reference to FIGs. 3 and 4J. The laundry washing machine illustrated in FIGs. 3 and 4 may be a horizontal axis washing machine. Naturally, the washing machine according to the embodiment of the present invention and a method of controlling the same are not limited to the horizontal axis washing machine.
As illustrated in FIGs. 3 and 4, the basic configurations of the washing machine according to the illustrated embodiment may be similar to those of a conventional general washing machine. Basically, [configurations such as a box 100, a tub 200, a drum 300, a door 400, a gasket 500, a wash heater 600, and a drive unit 710-720 can be similar to those of a washing machine. conventional general washing clothing.
Suspension structures such as dampers 210 in the laundry machine according to the illustrated embodiment may be similar to those of the conventional general laundry machine.
However! the garment washing machine according to the illustrated embodiment may include a first wash water passage 150 and a second wash water passage 160. The first wash water passage 150 and the second wash water passage 160 may be separate from each other.
Both the first wash water passage 150 and the second wash water passage 160 can receive wash water from an external water supply source. The garment washing machine can receive wash water from the external water supply source through an external hose connected to the external water supply source. Thus, wash water supplied from outside the garment washing machine can reach desirable positions inside the garment washing machine through different passages, respectively.
In detail, the first wash water passage 150 and the second wash water passage 160 can communicate with the tub 200. Consequently, although the wash water is supplied through different supply passages, the wash water can be collected in the vat 200, starting from the bottom of the vat 200. Due to the different delivery passages, however, there may be differences as follows.
The first wash water passage 150 may be provided to supply wash water from the external water supply source to the drum 300 through a detergent box 153. For such a function, the first wash water passage wash 150 may include a first water supply valve 151. First wash water passage 150 may also engage a first water supply hose 152 to communicate first water supply valve 151 and detergent box 153.
The first water supply valve 151 is selectively open or 30 closed. Consequently, when the first water supply valve 151 is opened, the first wash water passage 150 can be opened. Thus, when the first water supply valve 151 is opened, wash water is supplied through the first wash water passage 150.
In addition, the first wash water passage 150 may include a first supply hose 154 to communicate the detergent box 153 and the interior of the drum 300. The first supply hose I 154 may extend through the gasket 500 Consequently, wash water can be directly supplied to the interior of the drum 300 through the first water supply hose 154. The first water supply hose 154 is disposed above the port 400 and, as such, wash water. it falls onto the wash garment received in a lower portion of the drum 300. Consequently, wash water supplied through the first supply hose 154 mo has at least a portion of the wash garment received in the drum 300.
Wash water supplied to the interior of the drum 300 may be introduced into a lower portion of the bowl 200 through through holes 310 of the drum 300 illustrated in FIG.
In this regard, the first wash water passage 150 may be a passage for supplying wash water from the external water supply source to the drum 300, in detail, an upper portion 15 of the drum 300, through the housing. detergent 153. Naturally, the first wash water passage 150 may include a passage for supplying wash water from the interior of the drum 300 to the lower portion of the bowl 200 through the through holes 310 of the drum 300.
By virtue of the provision of the| first pass of washing water 150, 20 garments to be washed are wetted from an earlier stage of water supply. Consequently, it may be possible to expect reduced washing time and improved washing effects through quick wetting of garments to be washed.
In the illustrated embodiment, the second wash water passage 160 25 can be separated from the first wash water passage 150. That is, it is desirable to provide parallel wash water passages which supply wash water through different paths, respectively.
In detail, the second wash water landscape 160 can be provided to supply wash water directly from the external water supply source to the interior of the tub 200 while preventing the wash water from passing through the drum. 300.
The next wash water passage 160 may include a second water supply valve 161. The second water supply valve 161 may be selectively opened. Consequently, when the second water supply valve 161 is opened, the second wash water passage 160 can be opened to supply wash water.
The second water supply valve 161 can be separated from the first water supply valve 151. Accordingly, the first and second water supply valves 151 and 161 can be controlled independently of each other. This means that valves 151 and 161 can be opened simultaneously or only a selected one of valves 151 and 161 can be opened. That is, the first and second wash water passages 150 and 160 can be selectively opened.
In addition, the second wash water passage 160 may include a second supply hose 162. The second supply hose 1162 is connected to the second water supply valve 161 and, as such, supplies wash water to the bowl 200 when the second water supply valve 161 is opened. {
In this case, the position in which the second supply hose 162 communicates with the bowl 200 is different from the position in which the first supply hose 154 communicates with the bowl 200 or drum 300. In other words, the first and second supply hoses 154 and 162 may have different wash water supply positions, respectively.
In detail, the second supply hose 162 can directly communicate with the tub 200 in order to prevent washing water from entering the drum 200. In other words, washing water supplied through the second supply hose 162 can be prevented from contact washing clothes received in drum 300.
In more detail, the second supply hose 162 can communicate with a port of | rear water supply 163. Accordingly, the second rinse water passage 160 can supply rinse water into the tub 200 through the rear water supply port 163.;
As illustrated in FIG. 3, the rear water supply port 163 may be disposed to a rear portion of the bowl 200. In detail, the rear water supply port 163 may be disposed to a top side of the rear portion of the bowl 200. Preferably, the rear water supply port 163 is disposed on the rear wall of the rearmost portion of drum 300. ■
Consequently, wash water supplied through the rear water supply port 163 is introduced into the tub 200 on the outside of the drum 300. The introduced wash water can be collected in the lower portion of the tub 200. According to the position of the port from the rear water supply 163, wash water supplied through the second wash water passage 160 can be supplied to the interior of the tub 200 without wetting the laundry garment.
Meanwhile, the position and shape of the rear water supply port 163 can be determined such that the rear water supply port 163 corresponds to a rear surface of the tub 200. In other words, wash water supplied through the Rear water supply port 163 may be directed to the rear surface of the bowl 200. To this end, the rear water supply port 163 may be disposed at a position just above the rear surface of the bowl 200.
The rear water supply port 163 may also be formed to be angled. That is, the rear water supply port 163 can be tilted back. Consequently, wash water supplied through the rear water supply port 163 can flow to the lower portion of the bowl 200 along the rear surface of the bowl 200.
The rear water supply port 163 may be disposed at a more rearward position of the tub 200, as compared to the position illustrated in FIG. 3. The rear water supply port 163 may also be further angled as compared to the case illustrated in FIG. 3.
The position and direction of wash water supply of the rear water supply port 163 can be determined in order to achieve various goals and effects additional to the goals and effects described above. This will be described later.
FIG. 5 is a block diagram of the laundry machine according to the illustrated embodiment.
Operation of the washing machine is controlled via an 805 controller. Generally, the 805 controller can be provided within an 800 control panel (FIG. 6). Generally, the control panel 800 is arranged on a top of the washing machine to allow the user to manipulate the control panel 800 and the status display.
The 805 controller can control operation of the washing machine based on signals entered through various user interfaces (Uls), for example, an 810 cycle selector or the like provided on the 800 control panel. garment wash is operated according to a cycle selected via the cycle selector 810 and an option selected via an option selector which is not shown.
Information regarding the selected cycle and option, time information, and current status information can be displayed in a non-shown display, under the control of the 805 controller.
Controller 805 can control actuation of the first and second water supply valves 151 and 161. By controlling the first and second water supply valves 151 and 161, it may be possible to control an amount of washing water supplied. Controller 805 can also control a wash water supply position such that the wash water supply position is varied, by controlling water supply valves 151 and 161 as described above.
Controller 805 can control actuation of wash heater 600. Consequently, wash heater 600 can be actuated such that the temperature of the wash water reaches a desirable temperature. The wash heater 600 can also be prevented from overheating.
The 805 controller can control the drive of a 710 motor of the drive unit. By controlling the engine 710, it may be possible to appropriately determine a time when the engine 710 should be activated and a pattern of actuation of the rjnotor 710 (e.g. drum tipping drive 300, drum centrifugation drive 300, drive spin drying drum 300, etc.).
Tip-over drive means drum drive causing garments to be washed inside the drum to tip over according to drum rotation. 25 Spin drive means drum drive making garments for washing inside the drum rotate along with the drum while in close contact with an inner surface of the drum in accordance with high speed rotation of the drum. In this regard, the drum rotation speed during centrifugation drive should be higher than the drum rotation speed during tipping drive.
Spin drying drive is similar to spin drive. However, the drum rotation speed during spin drying drive may be higher than the drum rotation speed during spin drive. This is because 35 c triggering and spin drying is triggered to remove moisture through centrifugal force.
The 805 controller can control the triggering of a 620 drain pump. Consequently, draining can be performed at a time when draining is required.
The 805 controller is always connected by signal with a water level sensor 630 and a temperature sensor 610. Consequently, the controller 805 can receive desirable water level information and temperature information at a specific time through sensors 610 and 630 .
Based on the water level information provided by the water level sensor 630.1 the controller 805 can control actuation of the water supply valves 151 and 161. Consequently, it may be possible to supply wash water at a desirable water level.
Based on the temperature information provided from the 6" 0 temperature sensor, the controller 805 can control actuation of the wash heater 600. Consequently, it may be possible to heat wash water to a desirable temperature.
FIG. 5 illustrates an example of control panel 800 in the laundry machine according to the illustrated embodiment.
The laundry garment machine can selectively perform a plurality of wash cycles to wash various articles of laundry garment. The garment-to-wash machine may also selectively perform a plurality of wash cycles in order to provide functionality in addition to washing garments to launder. In this regard, it is desirable to allow the user to easily select a desirable cycle from among the plural wash cycles.
The garment washing machine in accordance with the illustrated embodiment may include wash heater 600 which heats wash water as described above. Wash heater 600 can also generate steam. Steam can be supplied to the interior of the drum 300. In detail, steam generated in the lower portion of the bowl can be supplied to the interior of the drum 300 through the through holes 310 of the drum 300.
Steam generation through the wash heater 600 involves additional energy consumption. Therefore, it is desirable to allow the user to clearly check whether steam is used or not. To this end, in the illustrated embodiment, several cycles associated with steam can be provided. The 810 cycle selector can be provided for selecting a specific cycle among plural cycles.
Plural cycles may include runnable cycles of heating 820. That is, plural cycles may include cycles in which wash heater 600 may be fitted. When the user selects one of the executable 820 heating cycles, the selected cycle can be executed. In this case, the controller 805 can control the laundry washing machine to execute the selected cycle according to a predetermined schedule.
For example, runnable heating cycles 820 may include a normal cycle. When the user selects only the normal cycle, the normal cycle which includes washing, rinsing and spin drying can be executed according to a pre-determined schedule.
Naturally, the user can additionally select use of the scrub heater heater 600 according to a given option for the selected cycle.
In runnable heating cycles 820, actuation of wash heater 600 can be automatically or selectively performed in order to increase wash water temperature. That is, it may be possible to increase the temperature of the washing water in order to achieve an improvement in washing efficiency.
Generally, runnable 820 heating cycles may involve an option for wash water temperature selection. Before describing the executable heating cycles 820, an example of the normal cycle will be described.
The normal cycle can be a cycle in which the wash water temperature is automatically set to 40°C. In this case, when chilled water or tap water is supplied from the external water supply source, an operation of automatically heating wash water to 40°C can be performed. On the other hand, when 60°C is selected as a wash water temperature according to a given option for wash water temperature selection, an operation of heating wash water to 60°C can be performed. Naturally, “chilled water” or “tap water” can be selected as a wash water temperature according to the given wash water temperature selection option. In this case, heating of the washing water can be dispensed with.
In this regard, each of the executable heating cycles 820 may be an np cycle in which the wash water temperature is variable in order to achieve improved wash effects. Naturally, in this cycle, the user can select whether the scrub heater 600 should be activated or not.
Plural cycles may also include 840 heat exclusion cycles.' That is, plural cycles can include cycles in which actuation of wash heater 600 is excluded or limitedly excluded. Each of the heat exclusion cycles 840 may be a cycle in which actuation of the scrub heater 600 is excluded. That is, the 840 heat exclusion cycles can be programmed so that they do not include heating.
Calpr 840 exclusion cycles may include wash cycles for functional apparel or woolen apparel having the possibility of heat damage, a quick cycle for quick wash, etc. If necessary, therefore, the wash heater 600 can be automatically adjusted to heat wash water to a temperature of 30 to 40°C. Alternatively, a desirable wash water temperature may be selectable within a range of up to 30 or 40°C. Naturally, actuation of the wash heater 600 can be completely excluded.
Plural cycles can include 830 steam cycles. That is, plural cycles can include cycles in which steam is automatically used. In other words, each of the 830 steam cycles can be programmed to include steaming. In FIG. 6, an allergy care cycle 831 and a crease cycle 832 are illustrated as examples of steam cycles 830.
The user can select a desired specific cycle by rotating a rotary knob 815. When a specific cycle is selected, the washing machine automatically runs the selected cycle, and then completes the execution of the selected cycle. Lamps 816 can be provided on rotary knob 815. Lamps 81 f and can correspond to respective cycles. Consequently, the user can easily recognize which cycle is selected according to sequential turning on/off of lamps 816 during rotation of rotary knob 815.
Plural cycles can be intuitively distinguished from each other by the colors printed on the 800 control panel to indicate respective cycles. For example, the 830 steam cycles are printed in a red color to allow the user to intuitively recognize hot steam cycles.
Here, it can be seen that the plural wash cycles in the garment machine for washing according to the illustrated embodiment are distinguishable from one another according to whether the wash heater 600 turns on or not.
The garment washing machine may include heat exclusion cycles in which actuation of the wash heater 600 is completely excluded. The garment washing machine may also include cycles in which actuation of the wash heater 600 is selectable or is automatically included.
Cycles including activation of the wash heater 600 can be classified into an executable heating cycle and a steam cycle. Henceforth, differences between the executable heating cycle and the steam cycle will be described
Heating in the executable heating cycle can be similar to steaming in the steam cycle. That is, the wash heater 600 can be activated in both the heating operation and the vaporizing operation. However, there may be a fundamental difference between the heating operation and the recovery operation in terms of the wash water level during operation of the wash heater 600.
As illustrated in FIG. 4, various water levels can be determined in association with relationships between tub 200, drum 300, and wash heater 600.
According to a variation in the water level, there can be a water level A, at which the wash heater 600 is completely immersed in the water, a water level B, at which water from! wash reaches the bottom of drum 300, and a water level C, at which wash water reaches the inside of drum 300.
In a horizontal axis garment washing machine, washing is performed by driving a drum. In spite of such a system, the drum can be operated under the condition that the garment to be washed is in a state of being wetted by the washing water. In washing, i.e. washing using water, consequently, washing water can be stored to reach the inside of the drum. Therefore, a preferred water level for washing is at least water level C. j
Meanwhile, when the amount of laundry to be washed is increased, an increased amount of washing water can be provided. To this end, an increased amount of washing water is provided with an increased amount of clothing; to wash. This means that the washing water level is increased to be higher than the water level C when the amount of washing material is high.
Basically, an operation of determining the quantity of garments to be washed is performed for washing execution in the garment washing machine. That is, when a desired cycle is selected, and execution of the selected cycle is started, the garment quantity determination operation to wash is executed. According to a laundry quantity determined in the laundry quantity determination operation, the wash water level for water wash (main wash) is determined. Consequently, water supply is carried out until the level of the supplied wash water reaches the determined water wash level. If necessary, the wash heater 600 is activated after completion of the water supply, to increase the temperature of the wash water. Generally, main wash is performed by driving drum 15 300 after completion of water supply or completion of heating.
In this regard, heating can be an operation of turning on the wash heater under the condition that wash water is stored to reach the inside of the drum. Thus, at least a portion of the laundry garment is submerged in heated wash water.
In the illustrated embodiment, however, vaporization may be distinct from heating. In detail, the wash water level during steaming may be lower than the wash water level during heating.
As shown in FIG. 4, the wash water level during steaming can be lower than at least water level B, but higher than water level A. In other words, the wash water level can be adjusted to prevent clothing to wash received in drum 300 from contacting heated wash water. The wash water level can be also adjusted to prevent the wash heater 600 from being exposed to air.
The wash water level during steaming can be determined to always be lower than the wash water level during main wash which is water wash. That is, the wash water level during steaming can be determined between water level A and water level B, as the wash water level during main wash can be determined to be always higher than the level of water B. operation of classified co First, can be refe washing, in qu< of exclusion of heating poi Cycles removes creases. An allergen 831 illustrated in FIG. 6, and < may be the crease cycle 832 illustrated in FIG. 6. Cycle c and steam wash (pi steaming, is performed using wash water) That is, the steam wash cycle can be a cycle in which steaming and main advancing are performed during running of the cycle.
In the vaporizing option, the rinse heater 600 can be actuated on a water level for vaporizing. On the other hand, in the main wash operation, the wash heater 600 can be actuated on a water level for main wash. That is, the heating operation can be performed to perform the main wash operation. Of course, the differences between the steaming operation and the heating operation can be associated with wash water levels, as described above.
Steam cycles can include cycles including the steaming operation but excluding the main wash operation. That is, the steam cycles can be cycles where the main wash operation at the water level for steam cycle wash
To carry out the crease cycle, wash water can be drained out of the cell 200 for a predetermined time to (S1). For carrying out the vaporization operation, top water can then be supplied for a predetermined time t1. This operation can be a water-to-steam S2 supply operation.
As described above, water supply in the steam water supply operation S2 is performed such that the supplied water level i.e. the water level for vaporization. Consequently, the steam water supply operation can be performed until the water level sensor 630 detects the water level for steaming. In this regard, the predetermined time t1 in the steam water supply operation S2 can be an admitted water supply period. That is, the predetermined time t1 can be a maximum allowable water supply period. This time can be determined by taking into account a variation in water pressure. The preset time t1 can be set to around 2 minutes. This means that water supply can run for a maximum of 2 minutes. Typically, water supply can be terminated before 2 minutes have elapsed because the water level sensor 630 can detect the water level for vaporization before 2 minutes have elapsed.
The water supply in the steam water supply operation S2 can be carried out in a different manner than in a general wash cycle. that of a steam exclusion cycle.
In detail, when the crease cycle 832 is selected, the controller 805 controls the second water supply valve 161 to be opened in order to introduce wash water into the cubicle 200 through the second wash water passage 160. In other words , Controller 805 can control water supply such that wash water is prevented from coming into contact with washing garment received in drum 300.
The crease cycle may be a dry wash garment crease cycle without water washing. For example, the crease cycle can be a crease cycle of laundry garments such as a shirt that has been worn once by the wearer, without washing the laundry garment with water. In this regard, the crease cycle can be a crease cycle for garments to wash relatively easily and quickly by removing creases or odor without performing water slab.
Consequently, is it preferable that laundry garments are prevented from getting wet by washing water, to carry out the crease cycle. This is because, once laundry is wetted with wash water, it is necessary to dry for an additional time. That is, dressing the garment for washing is possible only after drying through the dryer or natural drying is carried out.
As described above, the crease cycle can be provided to allow the wearing of a shirt with creases removed soon after the crease cycle has been performed. Therefore, supplying water through the second wash water passage 160 is most preferred.
Meanwhile, the second wash water passage 160 can be an independent passagenr of the detergent box 152. That is, clean water such as tap water can always be supplied through the second wash water passage 160. On the other hand, the first pass of the wash water 160k connected with the detergent box 153. For this reason, detergent sludge or the like may remain in the first pass of the wash water 160. However, such detergent sludge does not cause any serious problem in association with water wash. This is because water washing is carried out using a relatively large amount of washing water.
However, the second wash water pass 160 is an independent passage of detergent sludge or the like. Consequently, detergent sludge or the like does not enter the interior of the bowl 200.
Theoretically, it is difficult to completely prevent laundry garments from coming into contact with wash water introduced through the second wash water pass 160. This is because it is impossible to avoid the possibility that small droplets formed following collision of the wash water cc There the tub 200 can be inserted into the drum 300.
In this case, it is very undesirable for detergent sludge to be introduced into the laundry garment during the wrinkle cycle in which no water wash is carried out. This is because detergent deposits can remain on the garment for washing after the crease cycle is completed.
In this regard, it is preferred that the supply of wash water in the crease cycle is carried out through the second wash water pass 160, as described above. In this case, it may be possible to supply only clean water to the interior of the tub 200. Consequently, it may be possible to prevent contaminants such as detergent sludge from being transferred to garments for washing.
After completion of the steam water supply operation S2, a recovery operation S3 can be carried out. Vaporizing operation S3 may be a steam generation operation by driving wash heater 600. Alternatively, steaming operation S3 may be an operation of simultaneously performing steam generation and transfer of steam into drum 300.
Activation of the scrub heater 600 during the S3 steaming operation can be performed intermittently. Instead of such a drive method, large amount of energy can be consumed for increase in water temperature and water vaporization. For this reason, it is preferred that the wash heater 600 is actuated in a continuous manner. According to such a drive method, steam can be generated continuously during the steaming operation S3.
The time required for the S3 vaporization operation is variable. This is because the time required for the S3 steaming operation can be varied according to the amount of wash water for steam generation (associated with the water level), the wash heater capacity 600, and a temperature of x is determined heating of the wash heater 600.
In addition, overheating of the scrub heater 600 in steaming operation S3 must be avoided. This means that it is necessary to prevent the scrub heater 600 from being activated in a state by being exposed to air.
In accordance with the illustrated embodiment, therefore, it is preferred that the actuation time of the wash heater 600 during the steaming operation S3 is controlled to be variable. That is, it is preferred that the period of time that actuation of wash heater 600 is continuously executed from a time when actuation of wash heater 600 starts until actuation of wash heater 600 is stopped is controlled to be variable. Furthermore, a maximum allowable amount of the period can be pre-determined. Such maximum allowable value 35 can be determined by taking into account the capacity of the washing heater 600 and the amount of washing water in the water level for steaming.
Vaporizing operation S3 may include a control operation of !. i temperature and a time control operation in association with control 5 of the wash heater 600. The isom of a time t2 necessary for the temperature control operation and a time t3 necessary for the time control operation can be the time required for the S3 vaporization operation, namely, a time t4.
Here, the time control operation can be a continuous drive operation of the scrub heater 600 for a pre-determined time. Time t3 can be the predetermined time.
Naturally, the time t3 of the time control operation can be pre-determined to be a maximum allowable time. That is, time t3 can be predetermined to be a maximum allowable time while being variable according to time t2 of the temperature control operation. Consequently, the time t4 required for the S3 vaporization operation can be substantially variable by the times t2 and t3.
In detail, the temperature control operation may be an operation of continuously driving the wash heater 600 until the heating temperature of the wash water reaches a target temperature, namely, a predetermined temperature T1. In this regard, the target temperature can be a fixed value, but the time required for the heating temperature to reach the target temperature can be variable. This is because there are causes such as a deviation in the amount of wash water, a deviation in the voltage applied to the wash heater 600, a deviation in the initial temperature of the wash water, and item differences of t । clothes for washing.
The pre-set temperature T1 can be set to be lower than the boiling point of water, namely 100°C. This is because the time control operation follows after the temperature control operation. That is, the: wash heater 600 is continuously activated in the time control operation, until after the temperature control operation. In other words, the predetermined temperature T1 is set as described above in order to ensure a sufficient steam generation time while preventing wash water from overheating.
After actuation of the washing heater 600 starts in the steaming operation S3, the temperature of the washing water is gradually increased, as shown in FIG. 8. When the[temperature of the wash water approaches the boiling point of water, ordinarily 100°C, the gradient of temperature increase 5 of the wash water can be varied.
After garment machine operation experiments to wash in 1 ; In a warming environment, it can be seen that the temperature rise gradient of the wash water becomes mild at around 95°C. This may be because a large portion of heat to heat wash water is used as the Japorization heat.
In this regard, in the illustrated mode, the predetermined temperature T1 in the temperature control operation can be set to be around 95°C. Control operation of (temperature can be continued until temperature sensor 610 detects the predetermined temperature T1. Time t2 I.i may be the time required until the predetermined temperature T1 is reached. Consequently, time t2 it can be a variable time.
The predetermined temperature T1 can be detected by the sensor i j. temperature 610 which is disposed in the vicinity of wash heater 600. That is, temperature sensor 610 may be provided to detect a temperature in a position very close to an area where heat is generated. In FIG. 4, an example of the [temperature sensor 610 disposed on one side of the wash heater 600 is illustrated.
Thus, the temperature sensor 610 does not directly detect the temperature of the wash heater 600, but very quickly detect the temperature of the wash water heated through the wash heater 600.
Meanwhile, time control operation follows temperature control operation. Naturally, the wash heater 600 is continuously fired during the time control operation. In other words, activation of the washing heater 600 is maintained for the predetermined time t3 after completion of the temperature control operation. Naturally, 6 preset time[of t3 can be a fixed value.
The time; pre-determined t3 can be set appropriately, taking into account wash water Ida superheat, wash heater superheat 600, wash water quantity, and steam generation time. People of the present invention have found experimentally that it is desirable to pre-determine the time required for the time control operation to be around 2 minutes and 30 seconds. When the time control operation is performed as described above, it can be seen that the maximum washing water heating temperature is controlled to be lower than j103°C.
Naturally, the time required for the time control operation can be varied according to its relation to the predetermined temperature TI in the temperature control operation. This is because it is desirable to increase the time t2 when the predetermined temperature T1 decreases.
Thus, it may be possible to ensure prevention of overheating and a sufficient steam generation time as the S3 steaming operation is performed through the temperature control operation and the time control operation successively following the temperature control operation. Doravan' of I control
Temperature control operation can be continued for 7 minutes. Here, “7 minutes” can be a variable time. Subsequently, the time control operation can be continued for a fixed time of 2 minutes and 30 seconds. 30 seconds.
Meanwhile, temperature control operation can be continued for 8 minutes. Subsequently, the time control operation can be continued. In this case, however, the time control operation can be continued for 2 minutes, instead of the fixed time of 2 minutes and 30 seconds. Thus, the time control operation can be variably controlled according to the Òand temperature control operation. A maximum allowable value of the time control operation can be fixed. For example, the maximum allowable value can be 2 minutes and 30 seconds.
The action is only carried out for 7 minutes, as described above, the steaming operation can be carried out for 9 minutes and 30 seconds.
Since 'temperature control and time control are executed sequentially, it may be possible to prevent the wash heater or wash water from overheating. It may also be possible to ensure sufficient steam generation time. Since the maximum allowable value of the time required by the time control period is predetermined, the maximum allowable value of the execution period of the vaporizing operation is also predetermined. Consequently, there is no occasion that the time required for the 1 vaporization operation is no longer increased. I;
For example, if time control is not performed, there may be a possibility that the time required for the steaming operation may be excessively increased, in one (private environment. For example, extreme environments such as an excessive amount of wash water , an initial wash water temperature too low, an external voltage too low, an external environment too cold, and an excessive amount of garments to wash may be assumed. minutes pu more.
As described above, the crease cycle can be a cycle for creasing garments to be washed for a short period of time. Consequently, it is preferred that the time required for the crease cycle is predetermined. In this respect, it is undesirable to run the crease cycle for a longer time than the predetermined time, even in an extreme environment.
For this reason, the maximum allowable time required for the vaporization operation can be predetermined. The time required for the time control operation can be varied, taking into account the maximum allowable value of the time required for the vaporization operation and the time required for the temperature control operation. Naturally, the maximum (allowable time!) value required for the time control operation can also be pre-determined.
If necessary, time control operation can be dispensed with. Alternatively, the time control operation can only be performed for a time much shorter than the maximum allowable amount of time required for time control operation. Naturally, the I j time control operation can be performed for the maximum allowable time of it.
It may be possible to control the drum 300 by performing a tipping trigger during the S3 vaporizing operation. That is, a rinse operation can be performed during! the S3 vaporization operation.
Such tipping drive is adapted to effectively transfer steam to garments for washing. The tipping drive can also be adapted to create a steam environment within the bowl 200 as well as the drum 300. Consequently, steam can be spread evenly within the bowl 200 and drum 300 without! be concentrated locally, through the tipping trigger. Similarly, steam is supplied by the entire laundry garment without being supplied locally to the laundry garment.
Through the S3 steaming operation described above, laundry garments are exposed to a hot and humid environment. Odor molecules can be removed from clothing for washing in a humid, warm environment. Of course, in the 'I vaporization operation, it can be! It is possible to provide moisture over the entire area I i very large, as compared to a conventional case where the same amount of water as that of [spray operation S3 is used. This is because moisture in a vapor state is supplied to the garment for washing, rather than moisture in a water state.
When the S3 steaming operation is completed, an S4 crease removal operation can be performed. That is, steaming operation S3 and decreasing operation S4I can be performed sequentially. Controller 820 can control the steaming operation S3 and de-crease operation S4 to be performed sequentially, according to a predetermined schedule. I
The crease removal operation S4 can be an operation to increase the moisture content of garments to be washed using steam. The decreasing operation S4 can also be an operation of uniformly supplying steam to garments for washing in a steam environment.
The crease removal operation S4 may also be an operation of gradually lowering the internal temperature of the drum 300 or bowl 200. In this regard, the drum 300 may also be actuated during the crease removal operation S4, similarly to the operation of vaporization S3.
Generally, “tip drive” means driving a drum to and evating garments for washing from the bottom of the drum, and then releasing 1 garment for washing up. For this reason, laundry garments may include folded portions. Naturally, laundry garments can have variable exposed surfaces because they wash according to the tipping trigger. I I
The supply of steam in the S3 steaming operation is not carried out in such a way that steam is directly injected into the garment for washing under high pressure. The delivery of steam in the S3 steaming operation is carried out in such a way that laundry garments absorb steam in a steam environment. Therefore, it is desirable to evenly and maximally expose garment surfaces for washing to a steam environment.
Also, to remove creases, applying a certain amount of tension to laundry garments may be more effective. In other words, it may be possible to remove creases more effectively by providing moisture to a portion of the creased laundry garment while tensioning the creased portion of the laundry garment on opposite sides of the garment.
Therefore, triggering the taijibor in the S4 crease removal operation may include a centrifugal drive in order to achieve more effective and uniform garment steam supply for washing and more effective crease removal from the laundry garment. I
In centrifuge drive, the revolutions per minute (RPM) of drum 300 are relatively high, as compared to that in tipping drive. iko is, “spin drive” means a drive operation to spin the drum 300 such that washing garments overcome gravity. Generally, such a centrifugal drive can be performed at around 80 rpm. ;
In spin speeding, laundry garment is integrally rotated with drum 300 while in contact with an inner surface of drum 300. tension can be applied to laundry garments in accordance with rotation of tarfibor 300. Laundry garments may also come into contact with steam present in tub 200 through through holes 310. It may also be possible to supply steam more effectively to garments for washing. wash by generating steam flow in drum 300.
That is, it may be possible to increase the steam contact area of the laundry garment because the laundry garment may spread through the spin drive. It may also be possible to achieve improved crease removal effects because stress can be applied to garments for washing. In turn, the inventors have found that it is more preferable for the spin drive to be performed together with the tipping drive before the crease removal operation S4. This may be because the tipping drive is triggered to tip over garments to be washed or to modify superfluous exposure of garments for laundering by rinsing garments to be laundered. That is, this may be because the tipping drive is triggered to expose the entire outer surface of the garment for washing to a steam environment, rather than exposing particular portions of the garment for washing to the steam environment.
In this respect, it can be assumed that only the tipping drive is performed during the S4 crease removal operation. However, it may be possible to achieve an increase in moisture content and an improvement in the crease removal effects through the drive In other words, it may be possible to achieve an increase in moisture content, That is, to allow garments to be washed to absorb a relatively large amount of moisture, according to addition of spin drive, as compared to the case where only the tumble trigger is performed, it has also been found that an improvement in the decrease effects is achieved.
Therefore, an operation of performing drum tipping drive 300 and an operation of performing spin drive of drum 300 can be performed alternately during crease removal operation S4. That is, one tipping drive operation is performed for a predetermined period, and one (spin drive operation is then performed for a predetermined period. Each of the tipping drive and rotation drive operations can be executed multiple times. In other words, a drum drive cycle including the tilt drive option and spin drive operation can be repeated multiple times.
In order to easily carry out various drum drive controls as described above, the drive unit for driving the drum 300 may be a drive unit of direct connection type different from that of FIG. 4. Such drive unit of direct connection type is well known in the technical field and as such no detailed description of it will be given.
In detail, the time required for the tipping drive operation may be longer than the time required for the spin drive operation. For example, the total time required for repeated tipping drive operations can be around 10 times as well as the total time required for repeated rotation drive operations. This is because, if the spin drive time is increased excessively, the possibility of crease formation can be increased.
Therefore, the S4 crease removal operation can be performed, starting from the tipping trigger and ending with the tipping trigger. Centrifuge triggering can be performed for a relatively short time between successive tipping trigger operations.
As described above, spin trigger can be performed multiple times. In this case, centrifuge drive may exhibit different characteristics according to different running time points. First, a spin drive performed at an earlier stage of the S4 decrease operation can be adapted to achieve an increase in moisture content. Of course, such an increase in moisture content can be to achieve crease removal. This is because the spin drive at an earlier stage of the S4 crease removal operation is performed in a hot and humid environment.
However, the temperature and humidity of the environment are gradually inevitably lowered as the S4 de-crease operation proceeds towards a last stage of the same. This is because the interior of the bowl 200 is incompletely sealed from the outside of the bowl. Consequently, the amount of moisture in the interiors of drum 300 and bowl 200 is gradually reduced as the crease removal operation S4 proceeds towards the last stage of the same. This means a reduction in the moisture content of laundry garments.
In this regard, staged spin drive towards the last stage of the S4 de-crease operation can be carried out to reduce the moisture content of the laundry garment. That is, This spin drive can be spin drive to remove moisture a i | from garment to wash by generating airflow in drum 300 or tub 200.
Thus, a subsequent drying procedure following the crease cycle can be substantially dispensed with. In other words, laundry garments such as a shirt can be put on by the wearer shortly after completion of the crease cycle. In this regard, the crease cycle can be used very effectively.
Meanwhile, the crease cycle 832 is considerably different from the general water wash n cycle in terms of characteristics. That is, the crease cycle 832 is a cycle for quickly removing creases from garments for dry cleaning under the Conseqi garment to drum 300 condition through a transparent window provided in port 400.
The crease removal operation S4 can be performed for a predetermined time t5. As described above, the total crease cycle time can be predetermined. This is because the user may wish to wear garments to wash logJ after completion of the crease cycle. Therefore, the time required for the S4 crease strip cycle can be predetermined.
Based on the predetermined time t5, it may be possible to determine the number of tipping drive operations, the number of rotation drive operations, the time required for each drive operation, the time difference between each tilt operation. tipping drive and each spin drive operation, etc.
As the decreasing operation S4 proceeds, the internal temperature of the drum 300 or the temperature of the wash water can be gradually decreased. Consequently, when the crease removal operation S4 is completed, the crease cycle can be terminated (S6) after performing an S5 drain operation. The time required for the draining operation S5, t6 can also be predetermined.
As described above, the crease cycle can be completed without additional water supply after completion of the crease removal operation S4. The S4 crease removal operation can be performed for around 15 to 20 minutes.
In this case, therefore, the internal temperature of the drum 300 or the temperature of the garment to be washed after the crease cycle can be high. For this reason, when door 400 is opened after completion of the crease cycle, the user may experience inconvenience due to hot air. To this end, a cooling procedure to decrease the internal temperature of the bowl 200 or drum 300 may be necessary. Of course, the cooling procedure does not need to be carried out all the time. This is because the cooling procedure may not be necessary depending on the amount of garment to be washed or the maximum temperature of the wash water.
According to the illustrated embodiment, a cooling operation can be performed after completion of the crease removal operation S4, if necessary.
That is, a cooling operation can be performed between the de-crease operation S4 and the drain operation S5. The cooling operation can be an operation of forced lowering the temperature of the washing water and the temperature of the internal atmosphere of the washing machine 15 for washing, using cold water.
In detail, it may be possible to detect the wash water temperature via temperature sensor 610 after completion of the crease removal operation S4. Since the temperature sensor 610 can be arranged in close proximity to the wash heater 600, it may be possible to detect a maximum internal temperature of the bowl 200. Consequently, it may be possible to perform a temperature comparison operation detected by the temperature sensor 610 with a predetermined temperature T2.
The predetermined temperature T2 can be, for example, around 60°C.
As described above, drain operation S5 can be performed without performing a separate cooling procedure when the detected temperature is lower than the predetermined temperature T2. However, when the detected temperature is equal to or higher than the predetermined temperature T2, the cooling operation can be performed.
As shown in FIG. 9, a temperature detection operation can be performed for a very short time. During temperature sensing operation, there may be no variation in water level. The water level during the temperature sensing operation can be substantially lower than the water level for vaporization. That is, the water level during the operation of A. If you determine Tí 5 external water. 1
In this cé lavag water vaporization. F replenished istc 10 replenished by vaporization. C water level water can be a lower portion 15 That is, c water for steam< that the washing level is not a water level 20 is not reheated By another water level heating, steaming.
As a result of the difference between the level of water for spraying and the level of water supplied, an increased amount of wash water can be supplied without wetting garments to be washed. Consequently, it may be possible more quickly to lower the internal temperature of drum 300.
In this connection, it can be seen that the position and water supply direction of the rear water supply port 163 is important, as described above. Water replenishment or additional water supply can be performed to quickly lower the internal temperatures of the tub 200 and drum 300, rather than simply lowering the temperature of the wash water collected in the lower portion of the tub 200. Therefore, it is preferred that the heat exchange area of additionally supplied wash water is maximized
The rear water supply port 163 can be arranged to allow wash water supplied (through the rear water supply port 163 to flow downwards from the rear surface of the tub 200. In this case, the wash water is supplied through of the rear water supply port 163 can exchange heat with a large area of the bowl 200. Consequently, more rapid cooling can be achieved.
After completion of the additional water supply, tipping trigger can be performed for eg 2 to 3 minutes. Through tipping drive, Ide air flow is generated within the bowl 200 and drum 300 and, as such, rapid cooling can be achieved.
Upon completion of the tipping trigger, draining can be performed. Thus, running the crease strip cycle can be completed.
Until then, the cycle takes away creases (as an example of the steam cycles was described in detail.
Hereinafter, the steam wash cycle will be described in detail.
In FIG. 3, allergy care cycle 831 is illustrated as an example of steam wash cycles. Allergy care cycle 831 can be a cycle in which a spray operation is performed in conjunction with a water wash. Supply (Le water for main wash, where water wash is performed, ie supply of water up to the water level for main wash, can be performed through the first wash water pass 150. In other words, it may be possible to improve washing effects by wetting garments to wash by washing water and detergent from an earlier stage of the cycle.
The steaming operation in allergy care cycle 831 can be performed before the main wash. For vaporizing operation, supply water up to the level of! water for vaporization can be run. Supply of additional water can be carried out after completion of the vaporization operation. Here, additional water supply can mean supplying water up to the main wash water level.
Preferably, the supply of water to carry out the vaporization operation in the allergy care cycle 831 is preferably carried out through the second wash water pass 160, similarly to the crease cycle. However, it is more preferred that the water supply be performed through the first wash water pass 150 because the allergy care cycle 831 includes water wash.
That is, wash water and detergent can be supplied up to the water level for vaporization through the first wash water pass 150. Consequently, wash water and detergent can be supplied from an early stage of the allergic care cycle 831 Afterwards, a recovery operation can be carried out by supplying steam to the garment for washing.
In allergy care cycle 831, the steaming operation can be carried out under the condition that at least a portion of the laundry garment has been wet with washing water and detergent. Consequently, dressing room dressing for washing and contaminants and detergent dressing can be more actively reached through the steaming operation.
It is therefore preferred that I wash water is always supplied through the first pass of the wash water 150 in the wash cycle to I 1
steam in which water washing is performed. On the other hand, it is preferred that wash water is always supplied through the second wash water pass 160 in the steam cycle in which water wash is excluded.
In other words, the passage to supply wash water can be modified according to whether water wash is performed, even in a cycle where steaming is performed. In addition, the passage to supply wash water can be modified according to selected cycles, even when wash water is supplied to perform the same steaming operation in the selected cycles..
In detail, water supply for main wash using water can be performed through the first wash water pass 150, regardless of the selected cycles. On the other hand, water supply for steaming can always be performed through the second wash water pass 160.; selected.
For example, in a cycle including a water wash operation and a steaming operation, supplying water to carry out the steaming operation may be performed through the first wash water pass 150. In a cycle not including a steaming operation. vaporizing while excluding a water wash operation, however, the supply of water for carrying out the vaporizing operation may be performed through the second wash water pass 160.
Accordingly, the garment washing machine controller 805 according to the illustrated embodiment can perform a control operation to selectively open the first wash water passage 150 or the second wash water passage 160 according to a cycle selected through of cycle selector 810. Selection of a specific passage can be performed by selective opening of water supply valve 151 or 161.
In detail, in a water wash cycle (including a steam wash cycle, an executable heating cycle, and a heat exclusion cycle) in which wash water is supplied to the wash water level main, for water wash execution, wash water supply can be controlled to always run through the first wash water pass 150. In this case, therefore, wash water and detergent are supplied to the garment for washing from an early stage of the cycle and as such quickly wetting garments for washing and improved washing effects can be expected. Meanwhile, the main wash water level can always be higher than the steam water level, regardless of the selected cycles and amount of garments to wash.
As is evident from the above description, according to one aspect of the present invention, it may be possible to provide a washing machine capable of supplying wash water to an ideal position according to a selected cycle, through variation control. of the wash water supply position according to a selected cycle, and a method of controlling it.
