    FUNDAMENTALS OF THE INVENTION 1. Field of invention
    The present disclosure relates to a heat pump type clothing washing machine, such as a combined washer dryer or a clothes dryer, and more particularly to a pump type washing clothing machine. of heat to improve the dehumidification power in an evaporator using condensing water. 2. Description of the related technique
    In general, a garment washing machine for laundry treatment apparatus, such as a washing machine, a washer, a combined washer-dryer. The garment washing machine having a drying function such as a combined washing and drying machine is a device in which the laundry garment is in the drum in a state that the washing is completed and a dehydration process is carried out, supplying air into the drum to evaporate moisture from the laundry, thereby drying the laundry.
    For an example of such a dryer, the preceding dryer may include a rotating drum provided within a box for placing garments to be washed therein, a drive motor configured to drive the drum, a blower fan configured to blow air into it. of the drum, and a heating means configured to heat air drawn into the drum. Furthermore, the heating means can use high temperature electrical resistance generated by heat using an electrical resistance, or combustion generated by heat by gas combustion.
    On the other hand, air discharged from the drum contains the moisture of the garment for washing, and thus becomes high-temperature, humid air.
    Here, the dryer can be classified according to a method for processing high-temperature, moist air, and thus divided into a condensing (circulation) type dryer to condense the moisture contained in the high-temperature, moist air by cooling the air. below dew point temperature through a condenser while being circulated without discharging high temperature, moist air out of the dryer, and an exhaust type dryer to directly discharge the high temperature, moist air having passed through the drum out.
    In the case of the condensing type dryer in order to condense air discharged from the drum, the cooling process of the air below the dew point temperature must be carried out to heat the air through the heating means before it is supplied to the drum again. Here, the loss of thermal energy contained in the air is generated as it is cooled during the condensation process, and an additional heater or the like is needed to heat the air to a temperature necessary for drying.
    Even in the case of the exhaust type dryer, it is necessary to discharge high temperature and humid air to the outside and to receive outside air at a normal temperature, thus heating the air to the required temperature level through the heating means. In particular, thermal energy transferred by the heating means is contained in high temperature air being discharged to the outside, but it is discharged and wasted to the outside, thereby reducing thermal efficiency.
    Consequently, in recent years, clothing treatment apparatus for collecting energy needed to generate hot air and energy being discharged to the outside without having been used has been introduced to increase energy efficiency, and a clothing treatment apparatus having a system of heat pump was introduced as an example of the clothing treatment apparatus. The heat pump system can include two heat exchangers, a compressor and an expansion apparatus, and energy contained in the hot discharged air is reused in heating air being supplied to the drum, thus increasing energy efficiency.
    Specifically, in the heat pump system, an evaporator is provided on the exhaust side, and a condenser on an inlet side of the drum, and thus thermal energy is transferred to the refrigerant through the evaporator and then thermal energy contained in the refrigerant is transferred to the air drawn into the drum, thereby generating hot air using wasted energy.
    However, in a dryer using such a typical heat pump, the size of the condenser may be restricted due to the lack of space within which the condenser is installed, thus causing difficulty in achieving this condensing effect.
    Consequently, heat exchange efficiency may be reduced in the heat exchanger and refrigerant cooling may not be properly performed, thus reducing the dehumidification capacity. SUMMARY OF THE INVENTION

The second condenser may be formed with a refrigerant line extended from and integrally formed with the first condenser. For example, a first condenser refrigerant tube may be formed to extend from a first condenser refrigerant tube. The condensed water line refers to a level in the drying duct, which condensed water normally fills.

Here the lower end portion of the refrigerant tube of the first condenser can be placed above the condensing water line. Alternatively, the refrigerant tube of the first condenser can be arranged horizontally, for example in a tortuous pattern or a zigzag pattern. Then, the lower column or refrigerant tube level of the first condenser can be disposed in the condensing water line.
    The refrigerant tube of the second condenser can be arranged horizontally, for example, in a tortuous pattern or a zigzag pattern. Below the condensing water line.

DETAILED DESCRIPTION OF THE INVENTION
    Hereinafter, a heat pump type dryer in accordance with the preferred embodiment of the present disclosure will be described in detail with reference to the attached figures. The dryer is just one example of a garment washing machine in accordance with the present invention. The same can be applied to a combined washer-dryer and dryer and the like.
    Before the description, it should be noted that the terms and words used in the description and claims should not be limited and interpreted as being typical or literal, but rather should be interpreted as the meaning and concept following the technical concept of the invention on the basis of which the inventor can define the concept of terms and words to describe the invention in a better way.
    Consequently, since the embodiments described in the present disclosure and configurations shown in the figures are the most preferred embodiments only and do not represent all of the technical concepts of the invention, it should be understood that there may be several equivalent and modification examples that can replace them at the time of applying this disclosure.
    Hereinafter, the configurations and working relationships of a clothes dryer as an example for a washing machine according to the present disclosure will be described in detail with reference to the attached figures.
    FIGS. 1 and 2 are views illustrating the internal structure of a heat pump type dryer, and FIG. 3 is a block diagram illustrating the method of drying the heat pump. Furthermore, FIG. 4 is a view illustrating the circulation path of a refrigerant using a second condenser in accordance with the present disclosure, and FIG. 5 is a view illustrating dryer air passing through the evaporator and condenser according to the related art.
    Furthermore, FIGS. 6 and 7 are views illustrating a second capacitor in accordance with another embodiment of the present disclosure.
    With reference to FIGS. 1-3, the present disclosure may include a box 100 forming the exterior of the clothes dryer, and a drum 110 rotatably provided within the box. The drum is rotatably supported by a support (not shown) on the front and back sides of the drum and can be driven by a 10 motor.
    An inlet duct 170 provided in the casing for drawing outside air and supplying the air to an inner portion of the drum is provided in the vertical direction of the drum on the rear side of the drum. The inlet flow path through which the air drawn into the drum flows is formed by the inlet duct. In accordance with the present disclosure, air drawn through the inlet duct can be drawn in from outside the box separately from the drying duct 190.
    On the other hand, a heater 180 to heat the aspirated air to make it high-temperature air needed to dry the garment for washing can be provided inside the inlet duct 170. The heater 180 receives electrical energy to heat the air to be supplied. sufficiently and quickly to the drum, and additionally provides heating such that the refrigerant cycle is stably managed in a normal state. By these means, energy efficiency of a heat pump type garment washing machine can be improved and heat pump overload can be avoided.
    According to the preceding structure, the heat needed for drying can be sufficiently supplied in a short period of time, thus having a drying time-reducing effect. In other words, additional heating can be provided in a short period of time since the heating cannot be sufficiently supplied in a short period of time using only air in the circulation flow path with the drying duct.
    Air carried into the drum can be supplied through a circulation flow path formed in drying duct 190 separately from the air through the inlet flow path. The drying duct 190 is provided in the box to circulate air discharged from the drum when supplying it thereto.
    The air taken into the drum dries the garment for washing and is then taken to a front surface duct (not shown) located to a lower rear side of the drum and supplied to the drum again through the drying duct by means of a filter. fluff (not shown) or discharged to the outside of the box through an exhaust duct which will be described later.
    A blower fan 120 for sucking inside the drum to forcibly blow it out of the dryer can be provided in the circulation flow path of the drying duct.
    Here, an evaporator 130 and a condenser 140 are sequentially provided in a flow path formed by the drying duct. Evaporator 130 and condenser 140 as a heat exchanger type, according to the present disclosure, form a heat pump refrigerant cycle, thereby achieving heat exchange with air (Ad) in the circulation flow path by refrigerant flowing in. his.
    The air taken into the drum is heated by heater 180 in the inflow path or condenser 140 in the circulation stream to make it dry high temperature air at about 150-250°C when being taken into the drum . High temperature air is brought into contact with an object to be dried to evaporate moisture from the object to be dried. Evaporated moisture is to be contained in medium temperature air and exhausted out of the drum. At this point, in order to circulate the moist, medium temperature air and reuse it, the moisture must be removed. Since the moisture content in the air is affected by temperature, moisture can be removed by cooling the air. Consequently, the air in the circulation flow path is cooled by heat exchange with the evaporator 130.
    In order to supply the air cooled by the evaporator 130 back to the drum, it must be heated by high temperature air, and the heating of the air is carried out by the condenser 140.
    A refrigerant cycle exchanges heat with the environment using the phase change of refrigerant flowing through the inside of the refrigerant. Briefly described, the refrigerant is transformed into a low-temperature, low-pressure gas by absorbing heat from the environment in the evaporator, compressed into a high-temperature, high-pressure gas in the compressor, transformed into a high-temperature, high-pressure liquid by dissipating heat to the environment in the condenser, transformed into a liquid of low temperature and low pressure by dropping its pressure in the expansion apparatus, and is taken to the evaporator again. Due to the refrigerant circulation, heat is absorbed from the environment in the evaporator and heat is supplied to the environment in the condenser. The refrigerant cycle can also be referred to as a heat pump.
    In accordance with the present disclosure, the refrigerant cycle may include compressor 150 and expansion apparatus 160 along with evaporator 130 and condenser 140.
    The air flow path in heat exchange with the refrigerant cycle is illustrated in FIGS. 2 and 3. In other words, an arrow passing through the evaporator and condenser and a line connecting between the evaporator and condenser does not indicate the refrigerant flow path, but does indicate the air flow path in FIGS. 2 and 3, and the air is sequentially brought into contact with the evaporator and the like to effect heat exchange.
    For the configuration in more detail, as illustrated in FIG. 3, it is seen that evaporator 130 and condenser 140 are sequentially disposed, respectively, in the circulation flow path (a large circulation line formed along a bold arrow in FIG. 3) formed by drying duct 190.
    As illustrated in FIG. 3, the air (Ad) in the circulation flow path exchanges heat with the heat pump during the refrigerant cycle, specifically the air (Ad) in the circulation flow path dissipates heat in heat exchange with the evaporator, and absorbs heat in exchange for heat with the condenser. As a result, the air in the circulation flow path absorbs heat dissipated by itself again.
    In general, the evaporator and condenser are mainly responsible for the heat exchange during the refrigerant cycle, and the air from which heat is taken in the evaporator liquefies the moisture contained in it to exhaust it as condensation water, and dry air is heated by the compressor and condenser to be changed into high temperature dry air.
    In this way, the air changed into high temperature air in heat exchange with the refrigerant cycle through the circulation flow path is taken into the drum along with the air in the inlet flow path to participate in the drying process.
    Here, part of the air taken into the drum and used in the drying process is exhausted to the outside of the dryer, and part of it is reused, and supplied to the reused air by absorbing only part of the heat wasted using the refrigerant cycle. However, embodiments of the present invention may also be employed in a non-air exhaust circulation type dryer or an exhaust air type dryer, in which all the air is exhausted to the outside of the dryer.
    In the heat pump type clothes dryer, waste heat is typically collected using the refrigerant cycle, and the present disclosure provides a means of optimization not to cause an overload during the refrigerant cycle. In other words, in the case of a refrigerant cycle, the refrigerant heat exchange must be carried out by the phase change at the ideal operating temperature and pressure, and for this purpose, a heat exchanger such as an evaporator and a condenser, a compressor, an expansion apparatus and the like are used. Consequently, in order to collect more heat, the size of the heat exchanger or compressor is inevitably increased. However, in the case of a typical clothes dryer, it has a spatial restriction and therefore the heat exchanger, compressor or the like is limited in its size.
    Accordingly, in accordance with the present disclosure, heater 180 for heating the drawn in air to make it high temperature air necessary for drying laundry garments is provided within the inlet duct to continuously replenish the drawn in air with heat.
    In accordance with the present disclosure, heat can be replenished through heater 180 to sufficiently provide the heat needed for drying, thereby reducing drying time. Furthermore, in the case of a refrigerant cycle, the refrigerant heat exchange must be carried out by a phase change at the optimum operating temperature and pressure and, for that purpose, sufficient heating must be provided. Otherwise this can cause a problem such as a refrigerant being supplied to the compressor in a liquid phase or the like and therefore the cycle cannot be stably operated, thus reducing cycle reliability. Consequently, as disclosed herein, the air taken into the drum can be further replenished with heating by heater 180, and it is preferable that the refrigerant cycle can be stably operated in a normal state.
    Additionally, an additional blower fan 120 can be provided in the inlet flow path to provide more airflow. In addition, the additional blower fan provides more airflow and thus the heater 180 is not overheated in the inflow path. The configuration provided with the additional blow fan 120 is illustrated in FIGS. 2 to 4.
    On the other hand, the present disclosure can be configured such that part of the air is exhausted out of the box upstream of the evaporator in the circulation flow path. Consequently, as illustrated in FIG. 1, the present disclosure may additionally include an exhaust duct 15 branched from the evaporator upstream 130 into drying duct 190, and the exhaust duct is configured to exhaust some of the air out of the box upstream of the evaporator in the track. of circulation flow. The exhaust duct forms an exhaust flow path to discharge hot air exiting the drum to exhaust some of the air to the outside of the box.
    According to the preceding configuration, waste heat is absorbed from part of the moist, medium temperature air leaving the drum only within a range that can be processed by the refrigerant cycle, and the rest of the air is exhausted. Consequently, it may be possible to reduce energy waste as well as not cause an overload during the refrigerant cycle. Furthermore, it may be possible to reduce energy consumption as well as increase reliability for the operation of the refrigerant cycle.
    Hereinafter, a heat pump type clothes dryer for maximizing a condensation effect using a second condenser in accordance with the present disclosure to improve dehumidification capability will be described with reference to FIGS. 4th to 7.
    Referring to FIG. 4, a clothes dryer in accordance with the present disclosure may include an evaporator 130, a condenser 140, a compressor 150 and an expansion apparatus 160 such as a heat pump type dryer. It has already been sufficiently described above and therefore its description will be omitted below.
    In accordance with the present disclosure, condenser 140 may include a first condenser piece 140 configured to liquefy a high temperature, high pressure refrigerant circulated from the compressor; and a second condenser or a second condensing unit 141 configured to condense the refrigerant from the first condenser again to extra-cool the refrigerant during the refrigerant cycle, thereby improving the dehumidification capacity in the evaporator.
    Typically, refrigerant passes through compressor 150 to follow the path of condenser 140, expansion apparatus 160 and evaporator 130, and in accordance with the present disclosure, a separate second condensing unit 141 may be included therein when the refrigerant has passed through. of compressor 150 is condensed in condenser 140, thus improving the condensing effect.
    As described above, the extra-cooling level can be further increased through the condenser 140 and the second condensing unit 141 in the condenser to improve the dehumidification capacity in the evaporator, thereby increasing the efficiency of the heat pump.
    Furthermore, the second condensing unit 141 may additionally include a cooling fan 146 to improve the extra-cooling performance of a second condenser 143 in addition to the second condenser 143 separately provided herein. The cooling fan 146 can draw outside air at an ambient temperature to cool the second condenser 143.
    Here, for the heat pump dryer refrigerant cycle, refrigerant flowing into the tube from the condenser outlet passes through the second condenser before directly through the expansion apparatus (or expansion valve) to improve the dehumidification capacity in the evaporator to remove moisture from the dry flow path. Consequently, it has a structure in which refrigerant in the second condenser 143 is additionally extra-cooled and taken into the evaporator in a state of low refrigerant dryness through the expansion apparatus (e.g. expansion valve), thereby improving the capacity of dehumidification.
    However, according to the above embodiment, a separate cooling fan as well as the second condenser and connecting tube must be additionally provided to increase the refrigerant extra-cooling, thus causing an increase in the raw material cost of the product.
    Accordingly, in accordance with another embodiment of the present disclosure, as illustrated in FIG. 6, the second condenser 148 is formed below a condensing water line to a lower portion of the drying duct as a refrigerant line extending from the first condenser and integrally formed therein. In addition, the second condenser is cooled using condensed water, which is condensed water in the evaporator.
    In FIG. 5, a conventional heat pump structure comprising an evaporator 130 and a condenser 140 in a drying duct is shown. Evaporator 130 and condenser 140 are arranged at the same height and above the condensing water line (WL) of the drying duct, until condensing water (W) is collected. The refrigerant lines or refrigerant pipes (PE) and (Pc) of the evaporator 130 and the condenser 140 are connected together via the compressor 150.
    Referring to FIG. 6, in accordance with an embodiment of the present disclosure, the first condenser refrigerant tube 140 and the second condenser refrigerant tube are intrusively formed on the same heat dissipation fins.
    Here, considering the arrangement of the first condenser and second condenser inserted into one or more heat dissipation fins, the refrigerant tube PCi of the first condenser is vertically arranged in a zigzag or sinuous pattern, and the end portion more The lower part of the condenser pipe thereof is disposed on or above the condensing water line WL, and the second condenser refrigerant pipe PC2 148 is horizontally disposed below the condensing water line. Horizontally or vertically arranged respectively refer to a plurality of subsequent mixed products of the condenser refrigerant tube being arranged in a vertical or horizontal plane with respect to the installed condenser.
    Vertical or horizontal can thus refer to the main flow direction of the refrigerant in the refrigerant tube.
    Consequently, it may not be necessary for the condenser 140 to be cooled with a separate cooling fan for cooling the condenser, and space utilization is improved, thereby promoting economic efficiency.
    According to the above embodiment, the second condenser 148 can be considered as a partial lower portion of the condenser 140 being submerged under condensing water (W), and the relevant lower portion of the condenser exhibits a structure to improve the extra-cooling efficiency of the condenser using condensed water. Consequently, a portion of the tail end on the outlet side of the tube exiting condenser 148 must be submerged under the condensing water to achieve extra-cooling without reducing condenser performance.
    Considering another actuation means of the present invention with reference to FIG. 7, the second condenser 148 is disposed below the condenser water line in a portion of the drying duct as an independent refrigerant line separate from the first condenser 140 to cool the second condenser using condenser water generated by the evaporator.
    As illustrated in FIG. 7, the first condenser heat-dissipating fin 140 and the at least one second condenser heat-dissipating fin 149 can be configured as independent heat-dissipating fins separate from each other, respectively.
    According to an embodiment in FIG. 7, the refrigerant circulation line (Pd) in the first condenser and the refrigerant circulation line (Pc2) in the second condenser can preferably be connected by a separate refrigerant circulation line that does not penetrate the heat dissipation fin.
    Consequently, with reference to FIG. 7, the refrigerant (Pd) circulated from the compressor (not shown in the figure) is completely circulated through the condenser 140, and then circulated again through the second condenser 149 via a separate refrigerant circulation path.
    Here, the refrigerant circulation (Pc2) of the second condenser 149 may be submerged under the condensing water surface (W), that is, below the condensing water line (WL) of the drying duct. In accordance with the present embodiment, an additional cooling fan according to the above embodiment can be provided to one or both parts in order to maximize cooling efficiency. However, a cooling function can already be promoted through the condensing water (W) produced by the evaporator 130 without having an additional cooling fan according to the present embodiment, thus avoiding an additional configuration as well as maximizing space utilization.
    Consequently, it is preferred that the refrigerant pipe PCi of the first condenser 140 is vertically disposed, for example in a zigzag pattern, and the lower end portion of the refrigerant pipe Pd is placed so as not to be contacted with water from condenser in the condensing water line (WL), and the refrigerant pipe PC2 of the second condenser is arranged horizontally below the condensing water line, for example, in a zigzag pattern to be submerged under condensing water.
    Accordingly, in accordance with the present embodiment, the second condenser itself has a separate independent condenser structure and the second condenser has a structure being submerged under the condensing water. Consequently, refrigerant that has passed through the condenser can be extra-cooled while being circulated through the second condenser submerged under condensing water, and as a result, a cooling fan that was necessary for the use of an extra-cooling period in the mode previous space is not needed, and the cost is reduced and additional space is not occupied, thus increasing spatial efficiency.
    The aforementioned embodiments are merely preferred embodiments of the present disclosure to enable persons ordinarily skilled in the art to which the present disclosure belongs (hereinafter, referred to as "those skilled in the art") to easily implement a heat pump type clothes dryer to improve extra-cooling performance using condensing water in accordance with the present disclosure, and the present disclosure is not limited to the above embodiments and the attached figures, and therefore the scope of rights of the present disclosure is not limited thereto. Consequently, it should be understood by those skilled in the art that various substitutions, modifications and changes can be made without deviating from the technical concept of the invention, and it should be clearly understood that portions which can be easily changed by those skilled in the art will fall within the scope of the rights of the invention.
