    image 1 STEAM GENERATION SYSTEM, STEAM IRONING DEVICE AND PROCEDURE TO OPERATE A STEAM GENERATION SYSTEM
    DESCRIPTION
    5 Field of the invention
    The invention refers to a steam generation system comprising a steam generator, made as a high pressure steam generator, a storage tank, and a pump for transporting water from the storage tank to the steam generator. Also, the invention refers to an ironing device to
    10 steam with a steam generation system of the aforementioned type, as well as a method for operating a steam generation system.
    Background of the invention
    In a steam generation system of the aforementioned type, steam is generated in the steam generator, which is provided for later use, for example, in a steam ironing device. To transport water from the storage tank to the steam generator, where the water evaporates, the pump is connected to the storage tank, on the one hand and, on the other hand, with the steam generator, for example, a steam boiler . In general, the pump is designed to operate in such a way that it is operated and, for this, a voltage is supplied, at least when it is constant that
    20 there is a need to supply water to the steam generator.
    During the operation of a steam generation system of the aforementioned type, noises are generated that can basically come from two sources, on the one hand, from the pump and, on the other hand, from the steam itself generated in the steam generator, which causes audible noise both during the steam generation process and when leaving an opening
    25 output, for example, when crossing channels laid on an ironing sole of a steam iron. The noise produced may be perceived by the user as annoying, so it is desirable that the noise emission that occurs during the operation of the steam generation system be reduced.
    In the international patent application WO 2013/068870 A1, it is proposed that in a
    A steam generator plate is provided with a flow stabilizing element in a channel through which steam flows, in order to minimize the production of noise when the channel passes through the steam and the resistance to flow in the channel. However, after extended use over time, lime deposits and leaks may appear. In addition, it has been shown that the effect of noise attenuation may diminish over time. On the other hand, the noise emission that occurs when the steam comes out is perceived by many users as less annoying, since said noise emission is directly subject to the control exercised by the user, that is, to the activation of a steam button during operation of the steam ironing device, thereby activating the steam outlet. It may even be desirable for the user to be notified through an acoustic signal that a steam jet has been effectively emitted. Thus, in the utility model DE 20 2011 106 502 U1, it is proposed that a sound generator that generates a sound in the case be provided at a mouth of a steam jet channel of a steam ironing device of a stream of steam flowing next to him.
    image2
    By means of the measures described above, no considerable influence is exerted on the noise emission caused directly by the pump, which is often perceived by the user as much more annoying, since it is not directly controlled by it.
    From the international patent application WO 2013/011473 A2, a domestic appliance is known which can be, for example, a steam iron or a coffee machine, in which a pump is connected to a water tank and with a water heater to transport water from the water tank to the water heater. During the operation of the pump, vibrations are transmitted to the housing and these, in turn, are transferred to the environment as sound or noise. To minimize the production of sounds caused by vibrations, the pump is provided with two leaf springs mounted on opposite sides of the pump, so that the pump can move in the direction opposite to the movement of a drive element. However, additional components are necessary for this, which results in a more complex structure and higher costs. Likewise, in this way only the sound conducted through the solid body of the pump, which comes out of the pump, can be minimized, while the sound power level remains largely unchanged.
    Technical problem
    The present invention solves the technical problem of providing an improved steam generation system, an improved steam ironing device and an improved method for operating a steam generation system. A steam generation system of the aforementioned type is provided, a steam ironing device with a steam generation system of the aforementioned type and a method for operating a steam generation system in which the greatest possible extent is avoided. mentioned disadvantages. With the invention, the attenuation of noise emission that occurs during operation is facilitated, without having to assume a decrease in reliability, an increase in costs or / or a limitation of the capacity of steam generation or , which is the same, of the available ironing power.

    Solution according to the invention
    The reference symbols have no restrictive effect on any of the claims, but should only improve their readability.
    The exposed technical problem is solved by a steam generation system with the characteristics of claim 1, by a steam ironing device with the characteristics of claim 9, and by a method with the characteristics of claim 11.
    A steam generation system according to the invention comprises a steam generator for supplying pressurized steam, a storage tank, and a pump for transporting water from the storage tank to the steam generator. The steam generator is a high pressure steam generator in accordance with IEC 60355, that is, it is a steam generator that is configured for steam generation in a steam boiler with a pressure of more than 50 kPa. The steam generator is preferably made as a steam boiler or pressure vessel with at least one heating element that serves to heat and evaporate the water supplied to the steam boiler
    or pressure tank. Likewise, a steam valve can be provided, through which the transmission of the steam generated to a steam outlet can be controlled, which can be arranged, for example, in an ironing sole of a steam iron. During operation of the steam generation system, the pump transports water from the storage tank to the steam generator, where it evaporates, the pump being operated in such a way that the desired amount of water is available in the steam generator, which is heated by the heating element, so that an amount of steam is supplied at a desired pressure and can be conducted, for example, to a steam outlet. Preferably, the pump is operable with a corresponding regulation, for example, by switching it on or off, depending on the need, controlled by a steam generation system control device. The pump can be made as a piston or membrane pump.
    image4
    A steam generating system according to the invention is configured to generate steam for the operation of a domestic appliance, for example, a steam ironing device, and can be comprised of the domestic appliance, that is, the steam ironing device .
    5 According to the invention, the pumping capacity of the pump is adjustable. Specifically, the amount of water transported by the pump per unit of time is adjustable by adjusting the pumping capacity. By adjusting the pump's pumping capacity, influence can be made on the noise emission caused by the pump, for example, by reducing the pumping capacity the acoustic power level can be reduced so much
    10 of the pump as the body sound caused by the movement of the piston of a piston pump, as well as the corresponding vibrations.
    According to the invention, it has been recognized that, on the one hand, noise emission can be reduced by decreasing the pumping capacity and that, on the other hand, a reduced pumping capacity is sufficient in many cases to achieve a result. desired, for example, a desired ironing result. In the case that a greater pumping capacity of the pump is necessary and, with it, a more intense steam generation, for example to remove very marked wrinkles of an ironing article with the iron, it is possible to adjust a pumping capacity of the correspondingly higher pump. If such steam generation capacity is not needed, that is, power of
    20 ironing, higher, can be worked with a reduced pumping capacity and with a correspondingly reduced steam generation and, therefore, with a lower noise emission.
    Since the pump is adjustable in a lower pumping capacity if it is sufficient to achieve a desired result, for example, a desired ironing result, and when it can be adjusted to a higher pumping capacity if it is necessary to obtain the desired result, a reduction in the emission of noise caused by the pump can be achieved together. However, a high steam generation capacity or, what is the same, ironing power, if necessary, is available. In this way, noise emission can be reduced in a surprisingly simple way, without
    30 that a decrease in steam generation capacity, or the ironing power, maximum available or the durability or reliability of the steam generation system, or an increase in costs, must be assumed.
    image5
    Preferred embodiment of the invention
    Subject of the dependent claims are advantageous embodiments and refinements, which can be used separately or in combination with each other.
    According to a preferred embodiment of the invention, the pumping capacity is
    5 adjustable by adjusting the voltage with which the pump is operated. By changing the voltage with which the pump is powered, the electric power of the pump can be influenced at the same time. In the event that the pump is turned on or off by a control device when the need for water is verified, the electric power of the pump consumed in the on state is modified, depending on the
    10 pressure conditions in the steam generator. Thus, a particularly simple, safe and economical realization is possible.
    Advantageously, the pumping capacity is adjustable in two or more degrees, in particular, at least one mode of operation of the pump with a maximum, not reduced, pumping capacity and at least one mode of operation with 15 units is available. reduced pumping capacity with respect to the first. The reduced pumping capacity is preferably determined in such a way that with it a sufficient steam supply can be achieved in many cases, for example, a sufficient ironing result for many types of fabrics when the steam generating system is used in a device steam ironing, so that the maximum pumping capacity is only necessary in a few cases. In general, noise reduction can be achieved with any pumping capacity that amounts to less than 100% of the non-reduced pumping capacity. Preferably, the reduced pumping capacity amounts to approximately 50-80% and, preferably, 65%, of the non-reduced pumping capacity or, which is the same, a reduced voltage with which the bomb
    25 amounts to approximately 70-90% and, preferably, 80%, of a non-reduced voltage. In this way, a reduction in the noise emission of the pump can be achieved very easily.
    Alternatively, the pumping capacity can be adjustable by more than two degrees or, also, continuously between a maximum value not reduced and a value reduced to a maximum that preferably amounts to <50% and, more preferably, to 45%, of the non-reduced value, or, the voltage with which the pump is operated can be adjustable by more than two degrees or continuously between a non-reduced voltage and a voltage reduced to the maximum that preferably amounts to <70% and, more preferably, 67% of the unreduced tension. The value reduced to the maximum of the pumping capacity or
    image6
    of the voltage can also have the value zero. In this way, the ironing power is adaptable particularly precisely to the specific requirements and in many cases of application an effective noise reduction can be achieved. If the voltage is set to 0, then the pump capacity is then set to 0, that is, no water is pumped to the water heater, which means that steam is not being supplied, that is, that in the device steam ironing is only possible without ironing.
    Preferably, the steam generator comprises a water level sensor, the pump being operable as a result of its signal. The water level sensor is preferably arranged in a steam boiler of the steam generator. It may be provided that the pump is put into operation by a control device if it is found that water is needed when determining the water level sensor that in the steam generator there is a quantity of water that is below a quantity of theoretical water. Upon reaching the theoretical value of the amount of water, the pump can be switched off again by the control device. By means of this mode of operation of the pump and in a regulation circuit of this type, the availability in the steam generator of a corresponding amount of water with a theoretical value of the amount of water and, with this, a safe supply of steam.
    According to a preferred embodiment of the invention, the steam pressure in the steam generator is adjustable, which is the steam pressure generated by the steam generator. In particular, a theoretical vapor pressure can be adjustable in a regulation circuit in which a heating element of the steam generator is operated in a regulated manner by a control device as a result of a signal from a pressure sensor that captures the steam pressure prevailing in the steam generator. By reducing the vapor pressure, a reduction in the amount of steam that is supplied to a steam outlet per unit of time can be achieved. Such a reduced steam stream may be sufficient in many cases, for example, to iron. Preferably, the theoretical pressure of the reduced vapor amounts to> 35% and, more preferably, 50%, of a theoretical pressure of the non-reduced steam. Therefore, by a lower vapor pressure, that percentage of the noise emission that is caused by the steam when exiting a steam outlet and / or crossing steam ducts or steam channels can be reduced, for example, a maze of an ironing sole of a steam iron.
    Preferably, the pump's pumping capacity is adjustable corresponding to the steam pressure set in the steam generator. The pumping capacity can be reduced by a control device of the generation system of
    5
    10
    fifteen
    twenty
    25
    30
    35


    steam corresponding to a reduced vapor pressure. Alternatively or additionally, the steam pressure can be adjusted in the steam generator corresponding to the adjusted pumping capacity, in particular, with a reduced pumping capacity, the steam generating system control device can adjust also a correspondingly reduced vapor pressure. In a regulation circuit in which the heating element is activated as a result of the signal from a pressure sensor, a theoretical steam pressure can be adapted for this to the adjusted pumping capacity. Thus, by way of example, a theoretical reduced vapor pressure, adapted to a reduced pumping capacity, can be adjusted by the control device as a consequence of a predefined characteristic field. Correspondingly, a reduced pumping capacity can be adaptable to a theoretical reduced vapor pressure as a result of a predefined characteristic field. In this way, optimized operation can be achieved with a reduced noise emission to the greatest extent possible and with the greatest possible steam generation capacity and, therefore, for example with the greatest possible ironing power, also with a capacity of reduced pumping. Preferably, the theoretical steam pressure is adaptable to the reduced pumping capacity such that, or else, the pumping capacity is adaptable to the theoretical pressure of the reduced steam such that the reduced pumping capacity does not lead to a considerably longer ignition time of the pump, in particular so that the amount of water corresponding to the amount of removable steam with the theoretical pressure of the reduced steam can be transported by the pump with the reduced pumping capacity against the pressure of the steam prevailing in the steam generator, without the pump having to remain on for longer or more frequently. Particularly advantageously, the steam pressure can be reduced with a reduced pumping capacity such that, when the steam leaves a steam outlet or, for example, when passing through a labyrinth of an ironing sole, the emission of Noise is reduced to a non-annoying level, although clearly audible, so that the steam output is acoustically controllable by the user.
    Preferably, an additional acoustic damping of the pump is provided by a silent embodiment of the pump and / or a damped housing of the pump, where the silent embodiment is designed for the different adjustable pumping capacities, or the dampened housing is optimized for the mode of operation of the pump with a reduced pumping capacity with respect to a maximum pumping capacity. Thus, a cushioned pump housing that minimizes


    The transmission of vibrations to a housing, for example, of a steam station, can be adapted to the frequency of mechanical oscillations produced by the pump in the operating mode with reduced pumping capacity. In this way, a greater reduction in noise emission can be achieved.
    Preferably, the steam pressure of the steam generator and / or the pumping capacity are manually adjustable by the user and, particularly preferably, to adjust the steam pressure, or the pumping capacity, an element of User-manageable control. Depending on the desired result, or on the requested steam supply, for example, on the basis of the desired ironing result, that is, on the requested ironing power, the user can therefore manually adjust the steam pressure, that is , the pumping capacity. In this way, it is created for the user, for example, the possibility of choosing between an operation of the steam generation system with reduced steam generation capacity, for example, of a steam ironing device with a reduced ironing power and a reduced noise emission, on the one hand and, on the other hand, an operation with a steam generating capacity, or, ironing power, maximum that can be linked to a greater noise emission. The user will generally perceive as less annoyance the greater noise emission, linked to a greater pumping capacity chosen in this way, since it has been chosen intentionally and linked to a greater power.
    A steam ironing device according to the invention comprises a steam generation system for generating steam for the operation of the steam ironing device, configured as described above. A steam ironing device according to the invention may comprise a steam iron and a steam station separated with the steam generation system. However, the steam ironing device can also be made, by way of example, as a steam iron in which the steam generation system is integrated and which therefore has an integrated steam generator and a tank Integrated storage and pump. In addition, a steam ironing device according to the invention can be made, by way of example, as a steam ironing press.
    Preferably, the steam ironing device comprises a steam iron and a steam station, which supplies steam to the steam iron, where the steam station comprises the configured steam generation system as described previously or be done as such. Therefore, the steam generator, the storage tank, and the pump are associated with the steam station, and the steam generated


    The steam generator can be supplied to the steam iron through a steam duct. With an embodiment of the steam ironing device of this type, a particularly good ironing result can be easily achieved while handling the steam ironing device is very convenient.
    5 According to a method according to the invention for operating a steam generation system, in particular, for operating a steam ironing device with a steam generation system, where the steam generation system comprises a steam generator made as a generator high pressure steam, a storage tank, and a pump to transport water from the storage tank to the steam generator,
    10 in a first mode of operation, the pumping capacity of the pump is set to a first value and, in a second mode of operation, it is set to a second value that is lower with respect to the first value. In this way, a reduction of the noise emission caused by the pump can be achieved together, without reducing the steam generation capacity or, what is the same, the maximum ironing power
    15 available to the user and without having to assume disadvantages related to durability, reliability or costs. The steam generation system, or the steam ironing device, is carried out as described above.

    Detailed description of an embodiment example
    A steam ironing device 10 according to the invention comprises a steam generating system made as a steam station 11 and a steam iron 20. The steam iron 20 is connected to the steam station 11 through a steam duct made as a flexible steam pipe 21 and through a power line 22. The steam station 11 comprises a high pressure steam generator, made as a steam boiler 14, for the generation of steam under pressure, which has an element of electric heating 15 for heating the steam boiler 14. Through the heating element 15, water located in the steam boiler 14 can be heated, so that steam can be generated with a certain pressure, where the pressure and temperature are correspond to each other in the interior space of the steam boiler 14. To regulate the steam pressure, a steam pressure sensor is not provided in the steam boiler 14 presented, which can be a temperature sensor disposed in the upper area of the steam boiler 14 that captures the temperature of the generated steam, from which the prevailing pressure in the steam boiler 14 can be determined. The boiler of steam 14 is connected to the steam hose 21 through a steam valve 13 made as an electrovalve, so that, by opening and closing the steam valve 13, a part of the pressurized steam can be driven from the steam boiler 14 to the steam iron 20 through the steam hose 21. The steam station 11 also has a filling system with a storage tank 16 for filling the steam boiler 14 and with a pump 17, through the which can be pumped to the steam boiler 14 the water located in the storage tank 16. In this way, it can be ensured that at all times there is enough water in the steam boiler 14 to generate steam. For this purpose, a water level sensor not shown is provided in the steam boiler 14, which can be made, for example, as a temperature sensor, arranged in the area of a water line corresponding to the theoretical level. of water, from whose signal it can be determined whether the water level is above or below the sensor location. In addition, the steam station 11 comprises a control device 12, which is connected to the pump 17 and the steam valve 13, as well as the heating element 15 and the pressure and water level sensor.
    The steam iron 20 has a control element in the form of a key 30, which is connected to the control device 12 so that, by pressing the button 30, the steam valve 13 can be opened. In this way, the user you can manually control the steam supply of the steam boiler 14 to a steam chamber, arranged inside the steam iron 20, and from it to the steam outlets provided in the ironing sole of


    the steam iron 20. Additionally, the steam iron 20 has another control element made as a rotating wheel 35, with which the temperature of the ironing sole can be controlled by controlling a heating device of the ironing sole.
    The rotating wheel 35 can move, for example, a mechanically functioning thermostat, usually installed next to the soleplate of the iron. Also called "mechanical plates" such plates. However, the rotating wheel 35 can also interact, for example, with an electric temperature sensor (for example, NTC) to regulate the temperature of the ironing sole. Such plates are also called "electronic irons."
    A control element of the steam station 11 made as a rotary knob 34 is connected to the control device 12, through which the pumping capacity of the pump 17 can be adjusted. Here, the pumping capacity can be chosen from a maximum non-reduced pumping capacity, in a first mode of operation or normal mode of operation, and a reduced pumping capacity in a second mode of operation or reduced mode of operation. In the second mode of operation, the noise emission caused by the pump 17 is reduced, in particular, the amplitude and / or frequency of the vibrations emitted by the pump 17 to the housing of the pump are attenuated with respect to the first mode of operation. the steam station 11. Likewise, in the second mode of operation the emission of noise transmitted by the sound propagated by the air inside and outside the housing of the steam station 11 is also reduced.
    As a result of the reduced pumping capacity, in the second mode of operation a smaller amount of water is transported to the steam boiler 14 per unit of time. In both the first and the second mode of operation, the heating element 15 is turned off or on by the control device 12 depending on whether the steam pressure determined by the steam pressure sensor corresponds or not to a pressure corresponding steam theory. To this end, the control device 12 is configured to record the measured value of the vapor pressure captured by the steam pressure sensor and to correspondingly direct the heating element 15. Also, the control device 12 is configured in such a way that, if the second mode of operation is set on the rotary knob 34, the theoretical steam pressure is correspondingly reduced and the heating element 15 is correspondingly directed to the pressure sensor signal so that in the second mode of operation, a steam pressure corresponding to the theoretical pressure of the reduced steam is reached in the steam boiler 14. Here, the theoretical pressure of
    5

    steam is adapted to the reduced pumping capacity so that the pump can transport a sufficient amount of water to the steam boiler 14 against the pressure prevailing in the steam boiler 14. In addition, the pump 17 is directed by the control 12 corresponding to the signal of the water level sensor, so that in the steam boiler 14 a water level corresponding to a theoretical water level is reached, where the pump is operated in the second mode of operation With a reduced pumping capacity. In the second mode of operation, and as a consequence of the reduced steam pressure, when the steam valve 13 is opened, a smaller amount of steam or, which is the same, a reduced steam current is conducted, towards the steam iron 20 and towards the steam outlets, so that here the noise emission caused by the steam coming out of the steam outlets or when the steam passes through a maze of the ironing sole of the steam iron 20 is also reduced.
    An exemplary evolution of the process according to the invention is shown in Figure 2. The reference symbols indicated below refer to Figure 1.
    During operation of the steam ironing device 10, the control device 12 shows in the simple embodiment, shown in Figure 2, of the method according to the invention if the first normal operating mode has been set on the rotary knob 34 or the second mode of reduced operation, which is also called "silent" mode. If this is the case, then the voltage U, with which the pump 17 is fed, is set to a reduced value Ured, and a theoretical pressure of the psoll steam is set to a reduced value pred. In the opposite case, the maximum values U0 and p0, initially adjusted, for the theoretical tension and pressure, respectively, are maintained. According to a variant of the procedure not shown, it can be provided that the voltage U is adjusted with the rotary knob 34 directly, for example through a potentiometer, at the maximum value U0 or at the reduced value Ured, as the case may be, and that the theoretical pressure of the psoll vapor be adjusted by the control device 12 correspondingly to this value. According to another variant of the procedure, which is also not shown, it can be provided that the theoretical pressure of the psoll steam is adjusted with the rotary knob 34 directly, for example through a potentiometer, at the maximum value p0 or at the reduced value pred, as the case may be, and that the voltage U be adjusted by the control device 12 correspondingly to this value. The reduced voltage Ured amounts, for example, to 70-90% and, preferably, 80%, of the non-reduced voltage U0, and the theoretical pressure of the reduced vapor pred amounts to approximately> 35% and, preferably , at 50%, of the vapor pressure not reduced p0. The bomb 17
    image7
    it is directed by the control device 12 in such a way that the water level w reached in the steam boiler 14, which is measured by the water level sensor, corresponds to a theoretical water level wsoll, which in the example represented is default; for this, the pump 17 is operated with the voltage U adjusted in each case, which in the "silent" mode 5 has the reduced value Ured. The heating element 15 is directed by the control device 12 in such a way that the steam pressure p reached in the steam boiler 14, which is measured by the pressure sensor, reaches the theoretical psoll pressure adjusted in each case. If the theoretical pressure psoll has been reached, then the heating element 15 is turned off until the pressure p prevailing in the steam boiler 14 has
    10 descended again as a result of steam extraction.
    The features disclosed in the foregoing description, the claims, and the drawings may be of importance both separately and in any combination for the practice of the invention in its different embodiments.
