[0055] The clothes dryer is a kind of household appliance for drying clothes, which puts wet clothes into the drum, and drives away the moisture in the clothes through the rotation of the drum and the flowing hot air to realize the drying of clothes. Generally, the clothes dryer includes a heat pump system, which includes a compressor 3, a condenser 4, a throttling element 5 and an evaporator 6 connected in sequence, and the working principle of the heat pump system is that the high-temperature and high-pressure gaseous refrigerant becomes high-pressure and medium-temperature liquid refrigerant after releasing heat through the condenser 4, at this time, it is reduced in temperature and pressure through the throttling part to become low-temperature and low-pressure gas-liquid two-phase refrigerant, and it is vaporized into medium-temperature and low-pressure gaseous refrigerant after absorbing heat in the evaporator 6, and it is compressed into high-temperature and high-pressure gaseous refrigerant through the compressor 3.

[0056] The flow direction of the circulating air in the clothes dryer is as follows: the circulating air is heated into high-temperature dry air after passing through the condenser 4, then enters the cylinder 11 through the impeller 12 to take away the water on the clothes, and flows to the condenser 4 again after being cooled and condensed into water by the evaporator 6. The liquid water condensed on the surface of the evaporator 6 falls into the water accumulation box 1 below the evaporator 6.

[0057] The water drainage mode of the water accumulation box 1 is arranged according to the internal structure of the clothes dryer. At present, the water drainage mode of the water accumulation box 1 is difficult to drain the water in the box completely, which causes the water accumulation box 1 to have accumulated water all year round. Since the water accumulation box 1 is installed inside the machine box, it is difficult to disassemble and clean the water accumulation box 1. Over a long period of time, bacteria and odors are likely to breed in the water accumulation box 1, which causes trouble and inconvenience to the user.

[0058] Therefore, the embodiment provides a water accumulation box self-sterilization structure for removing the accumulated water in the water accumulation box 1. Specifically, the water accumulation box self-sterilization structure comprises a heating device and a control device, and the heating device and the control device are connected.

[0059] The heating device is connected with the water accumulation box 1, and a water containing cavity is formed in the water accumulation box 1. The heating device can generate heat when working, and the generated heat can be used to evaporate the accumulated water in the water accumulation box 1, so that the water accumulation box 1 remains dry, reduces the breeding of bacteria and the generation of odors, and thus realizes self-sterilization.

[0060] The heating device is connected with the control device, and the control device is used to control the working state of the heating device. In the embodiment, the priority of the working of the water drainage pump connected with the water accumulation box 1 is higher than that of the working of the heating device, that is, the clothes treatment equipment first judges whether the water drainage pump needs to work, and then judges whether the heating device needs to work after determining that the water drainage pump needs to work and the water drainage pump has completed the work.

[0061] Regarding the water drainage pump, the water drainage pump is connected with the water accumulation box 1, for example, the water pump can be arranged in the water containing cavity of the water accumulation box 1, and the water drainage pump is used to pump out the water in the water accumulation box 1. In the related art, the water drainage mode of the water accumulation box 1 causes the water in the water accumulation box 1 to be difficult to drain completely, that is, there may still be accumulated water in the water accumulation box 1 after the water drainage pump has completed the work. Therefore, in the embodiment, the heating device is connected with the water accumulation box 1 to evaporate the residual accumulated water in the water accumulation box 1.

[0062] The priority of the operation of the water drainage pump connected to the water storage box 1 is higher than the priority of the operation of the heating device. Specifically, for example, the laundry treatment apparatus first determines whether the water in the water storage box 1 reaches a preset water amount, and if so, controls the water drainage pump to operate to drain the water in the water storage box 1, and if not, controls the water drainage pump not to operate. After the laundry treatment apparatus determines whether the water drainage pump needs to operate, and if so, after the operation of the water drainage pump is completed, the control device determines whether the heating device needs to operate. If so, the heating device is activated, and if not, the heating device is not activated. That is, the water in the water storage box 1 is mainly drained by the water drainage pump, and the heating device is mainly used to evaporate the residual water in the water storage box 1 that is not drained by the water drainage pump.

[0063] The laundry treatment apparatus includes a general controller that controls the operation state of the drying system, the operation state of the water drainage pump, and the like. The control device provided in the present embodiment can be integrated in the general controller, in which case the general controller controls the control state of the heating device. Of course, the control device provided in the present embodiment and the general controller are two different control devices that can be connected through a terminal.

[0064] For the determination of whether the water drainage pump needs to operate by the laundry treatment apparatus described above, in a specific example, a water amount detection device is provided in the water storage box 1, and the water amount detection device is used to detect whether the water amount in the water storage box 1 reaches a preset height value. If the water amount detection device detects that the water amount in the water storage box 1 reaches the preset height value, the general controller controls the water drainage pump to operate, and if the water amount detection device detects that the water amount in the water storage box 1 does not reach the preset height value, the general controller controls the water drainage pump not to operate.

[0065] For the determination of whether the heating device needs to operate by the control device mentioned above, the following scenarios are included.

[0066] For example, in one scenario, the control device controls the operation of the heating device according to the number of times the clothes treatment apparatus dries clothes, specifically, after the clothes treatment apparatus finishes drying clothes each time, instead of powering off immediately, the control device controls the heating device to work (of course, before the control device controls the heating device to work, the general controller has already completed the judgment of whether the drain pump needs to work, and during the drying process of the clothes treatment apparatus, the judgment of whether the drain pump needs to work is performed in real time, if the general controller judges that the drain pump needs to work, the control device controls the heating device to work after the drain pump has completed the work), so as to evaporate the moisture in the water accumulation box 1, when it is judged that the evaporation of the water accumulation in the water accumulation box 1 is completed, the control device controls the heating device to stop working, at this time, the clothes treatment apparatus issues an indication that the clothes drying is completed and powers off. Alternatively, the control device can accumulate the number of times the clothes treatment apparatus dries clothes, and the control device is provided with a preset parameter N, when the number of times the clothes treatment apparatus dries clothes is equal to N, after the Nth time of drying clothes is completed, instead of powering off immediately, the control device controls the heating device to work (of course, before the control device controls the heating device to work, the general controller has already completed the judgment of whether the drain pump needs to work, if the general controller judges that the drain pump needs to work, the control device controls the heating device to work after the drain pump has completed the work), so as to evaporate the moisture in the water accumulation box 1, when it is judged that the evaporation of the water accumulation in the water accumulation box 1 is completed, the control device controls the heating device to stop working. After the heating device works once each time, the number of times the clothes treatment apparatus dries clothes will be accumulated again.

[0067] When it is judged that the evaporation of the water accumulation in the water accumulation box 1 is completed, the control device controls the heating device to stop working, in one specific example, when the control device controls the heating device to work for T time, it is judged that the evaporation of the water accumulation in the water accumulation box 1 is completed; or in another specific example, when it is detected that there is no water accumulation in the water accumulation box 1, it is judged that the evaporation of the water accumulation in the water accumulation box 1 is completed.

[0068] In another scenario, the control device controls the operation of the heating device according to whether there is water in the water accumulation box 1. Specifically, the water accumulation box 1 is provided with a water accumulation detection device, which is connected to the control device and used to detect the water in the water accumulation box 1. It should be noted that the water amount detection device mentioned above is different from the water accumulation detection device. The water amount detection device is used to detect whether the water amount in the water accumulation box 1 reaches a preset height value, specifically, the water amount detection device is used to detect whether the water in the water accumulation box 1 is about to be full, while the water accumulation detection device is used to detect whether there is water in the water accumulation box 1. Therefore, the water accumulation detection device is different from the water amount detection device mentioned above. After the clothes treatment equipment finishes drying clothes each time, and after the control device judges whether the water pump needs to work and the water pump finishes working if it is judged that the water pump needs to work, the control device controls the operation of the heating device according to the signal transmitted by the water accumulation detection device, that is, when the water accumulation detection device detects that there is water in the water accumulation box 1, the control device controls the heating device to work, and when the water accumulation detection device detects that there is no water in the water accumulation box 1, the control device controls the heating device not to work.

[0069] In another scenario, the control device controls the operation of the heating device according to whether there is water in the water accumulation box 1. Specifically, the water accumulation box 1 is provided with a water accumulation detection device, which is connected to the control device and used to detect the water in the water accumulation box 1. It should be noted that the water amount detection device mentioned above is different from the water accumulation detection device. The water amount detection device is used to detect whether the water amount in the water accumulation box 1 reaches a preset height value, specifically, the water amount detection device is used to detect whether the water in the water accumulation box 1 is about to be full, while the water accumulation detection device is used to detect whether there is water in the water accumulation box 1. Therefore, the water accumulation detection device is different from the water amount detection device mentioned above. After the clothes treatment equipment finishes drying clothes each time, and after the control device judges whether the water pump needs to work and the water pump finishes working if it is judged that the water pump needs to work, the control device controls the operation of the heating device according to the signal transmitted by the water accumulation detection device, that is, when the water accumulation detection device detects that there is water in the water accumulation box 1, the control device controls the heating device to work, and when the water accumulation detection device detects that there is no water in the water accumulation box 1, the control device controls the heating device not to work.

[0070] The water accumulation box self-sterilization structure provided in the embodiment is connected to the control device, and the control device can control the working state of the heating device. The heating device is connected to the water accumulation box 1, and the heating device can generate heat when working. The generated heat can be used to evaporate the water in the water accumulation box 1, so that the water accumulation box 1 remains in a dry state, and the growth of bacteria and the generation of odor are reduced.

[0071] As to the position of the heating device on the water-accumulating box 1, in one embodiment, the heating device comprises an electric heating part 2, which is embedded in the wall plate of the water-accumulating box 1.

[0072] That is, in the present embodiment, a mounting groove can be provided on the inner side surface of the wall plate of the water-accumulating box 1, through which the electric heating part 2 is embedded in the water-accumulating box 1; or a mounting groove can be provided on the outer side surface of the wall plate of the water-accumulating box 1, through which the electric heating part 2 is embedded in the water-accumulating box 1; or a mounting cavity is formed in the wall plate of the water-accumulating box 1, when the electric heating part 2 is embedded in the wall plate of the water-accumulating box 1 through the mounting cavity, the electric heating part 2 cannot be seen from the inner side surface and the outer side surface of the water-accumulating box 1, of course, the electric wire connected with the electric heating part 2 needs to pass out of the outer side surface of the water-accumulating box 1.

[0073] In the present embodiment, the electric heating part 2 is embedded in the wall plate of the water-accumulating box 1, which not only can heat and evaporate the water accumulated in the water-accumulating box 1 when the heating device works, but also can fix the electric heating part 2 on the water-accumulating box 1 without other fixing members.

[0074] As to the position of the heating device on the water-accumulating box 1, in another embodiment, the heating device comprises an electric heating part 2, which is arranged on the inner side surface of the water-accumulating box 1.

[0075] That is, in the present embodiment, the electric heating part 2 can be fixed on the inner side surface of the water-accumulating box 1 through a fixing member, so that the water accumulated in the water-accumulating box 1 can be heated and evaporated when the heating device works.

[0076] In the present embodiment, the electric heating part 2 is arranged on the inner side surface of the water-accumulating box 1, which is beneficial to the direct contact between the water accumulated in the water-accumulating box 1 and the electric heating part 2, and is beneficial to the improvement of the evaporation efficiency of the water.

[0077] As to the position of the heating device on the water-accumulating box 1, in another embodiment, the heating device comprises an electric heating part 2, which is arranged on the outer side surface of the water-accumulating box 1.

[0078] That is, in the present embodiment, the electric heating part 2 can be fixed on the outer side surface of the water-accumulating box 1 through a fixing member. When the heating device works, the heat of the heating device is transmitted to the water accumulated in the water-accumulating box 1 through the wall plate of the water-accumulating box 1, so that the water accumulated in the water-accumulating box 1 can be heated and evaporated when the heating device works.

[0079] As to the electric heating part 2, in one embodiment, please refer to Figure 1 , the electric heating part 2 is an electric heating wire, which is distributed on the inner bottom surface of the water-accumulating box 1.

[0080] In the present embodiment, the electric heating wire is distributed on the inner bottom surface of the water-accumulating box 1, so that the water accumulated in the water-accumulating box 1 can directly contact with the electric heating part 2, which is beneficial to the improvement of the evaporation efficiency of the water.

[0081] As to the heating device, the above mentioned that the heating device comprises the electric heating part 2, as to the structure of the heating device, in another embodiment, the heating device comprises the drying system of the clothes processing equipment, the air duct connected with the drying system of the clothes processing equipment, and the driving fan located on the air duct, the driving fan is used to guide the high temperature air generated by the drying system to the water accumulation box 1 through the air duct.

[0082] In this embodiment, by guiding the high temperature air to the water accumulation box 1, the heat of the high temperature air can be transmitted to the water accumulation in the water accumulation box 1 through the wall plate of the water accumulation box 1, and then the water accumulation in the water accumulation box 1 is evaporated.

[0083] As to the drying system of the clothes processing equipment, in one example, the drying system of the clothes processing equipment is a heat pump system, the heat pump system comprises a compressor 3, a condenser 4, a throttling element 5 and an evaporator 6 connected in sequence; in another example, the drying system of the clothes processing equipment is a dehumidification system, the dehumidification system comprises a dehumidification rotating disc 7 and a rotating disc dehumidification device, the rotating disc dehumidification device can generate hot air to blow to the regeneration area; or, in another example, the drying system of the clothes processing equipment comprises both the heat pump system and the dehumidification system.

[0084] When the drying system is the heat pump system, the evaporator 6 and the condenser 4 of the heat pump system are arranged on the air duct, when it is needed to guide the high temperature air to the water accumulation box 1 through the drying system, the drying system and the driving fan are started, the circulating air flow is circulated to flow in the evaporator 6, the condenser 4 and the water accumulation box 1, so as to evaporate the water accumulation in the water accumulation box 1.

[0085] When the drying system is the dehumidification system, the air duct is connected with the rotating disc dehumidification device, when it is needed to guide the high temperature air to the water accumulation box 1 through the drying system, the drying system and the driving fan are started, the high temperature hot air generated by the rotating disc dehumidification device is guided to the water accumulation box 1, so as to evaporate the water accumulation in the water accumulation box 1.

[0086] When the drying system of the clothes processing equipment comprises both the heat pump system and the dehumidification system, the heat pump system can be used to provide the high temperature hot air to the water accumulation box 1, or the dehumidification system can be used to provide the high temperature hot air to the water accumulation box 1.

[0087] In this embodiment, by using the drying system to work to guide the high temperature air to the water accumulation box 1, it is convenient to evaporate the water accumulation in the water accumulation box 1.

[0088] In one scenario mentioned above, the water accumulation box self-degerming structure comprises a water accumulation detection device, the water accumulation detection device is arranged on the water accumulation box 1, the water accumulation detection device is connected with the control device, and the water accumulation detection device is used to detect the water accumulation in the water accumulation box 1, please refer to Figure 2The water accumulation detection device and the heating device are connected to the control device. In one embodiment, the water accumulation detection device comprises a detection circuit and two electrode sheets, the two electrode sheets are connected to the detection circuit, the detection circuit is electrically connected to the control device, and the two electrode sheets are arranged on the inner bottom surface of the water accumulation box 1.

[0089] In this embodiment, when there is water accumulation on the inner bottom surface of the water accumulation box 1, the two electrode sheets can conduct electricity through the water accumulation, and the detection circuit can send a detection signal to the control device. When there is no water accumulation on the inner bottom surface of the water accumulation box 1, a circuit is formed between the two electrode sheets, and the detection circuit cannot send a detection signal to the control device. At this time, the control device determines that there is no water accumulation in the water accumulation box 1.

[0090] In this embodiment, by providing a water accumulation detection device comprising a detection circuit and two electrode sheets, the presence or absence of water accumulation in the water accumulation box 1 can be accurately detected.

[0091] A laundry treatment apparatus comprises a water accumulation box 1 and a water accumulation box self-sterilization structure as described in any of the above embodiments. The water accumulation box self-sterilization structure comprises a heating device and a control device, and the heating device and the control device are connected. The heating device is connected to the water accumulation box 1, and the heating device can generate heat when it is working. The generated heat can be used to evaporate the water accumulation in the water accumulation box 1, so as to keep the water accumulation box 1 in a dry state and reduce the growth of bacteria and the generation of odor.

[0093] The heat pump system comprises a compressor 3, a condenser 4, a throttling element 5 and an evaporator 6 connected in sequence. When the drying system only comprises a heat pump system, the water accumulation box 1 is arranged below the evaporator 6 of the heat pump system, and the liquid water condensed on the surface of the evaporator 6 can fall into the water accumulation box 1.

[0094] The dehumidification system comprises a dehumidification turntable 7 and a turntable dehumidification device, and the dehumidification turntable 7 has an adsorption area and a regeneration area. The turntable dehumidification device can generate hot air to blow to the regeneration area.

[0095] In some embodiments, the dehumidification turntable 7 can be a honeycomb or corrugated turntable carrying a hygroscopic agent, capable of adsorbing and desorbing the absorbed water vapor to realize repeated desorption regeneration. In other embodiments, the dehumidification turntable 7 includes inorganic / organic fiber carriers (such as ceramic, glass fiber, MOFs, COFs, cordierite, etc.), and the fiber carriers are coated with a hygroscopic agent such as molecular sieve, which is uniformly distributed between the fiber carriers and the surface of the fiber carriers to realize adsorption of the moisture in the air flow. The hygroscopic agent can be, for example, zeolite, modified / synthetic zeolite, molecular sieve (including but not limited to single-crystal molecular sieve or mixed-crystal molecular sieve such as A-type molecular sieve, X / Y-type molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.), polymer hygroscopic agent, alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, and other materials with hygroscopic properties.

[0096] See Figure 3 In the example of Figure 3 , the turntable dehumidification device includes a heater 8, a first fan 9, and a cooler 10. Under the drive of the first fan 9, the air heated by the heater 8 can flow to the regeneration area, and the air flow passing through the regeneration area is dehumidified by the cooler 10 and then flows to the heater 8. When the drying system only includes a hygroscopic dehumidification system, the water accumulation box 1 is arranged below the cooler 10, and the liquid water condensed on the surface of the cooler 10 can fall into the water accumulation box 1.

[0097] Regarding Figure 3 the cooler 10 in the example, the cooler 10 can be a water-cooled heat exchanger. At this time, the cooler 10 is formed with a water inlet and a water outlet, both of which are in communication with a water flow pipeline in the cooler 10. Water can enter the water flow pipeline through the water inlet and be discharged through the water outlet. The water flowing in the cooler 10 can exchange heat with the air passing through the surface of the cooler 10. The water in the cooler 10 absorbs the heat in the air, causing the air to cool and condense water, thereby realizing dehumidification of the air passing through the regeneration area of the dehumidification turntable 7 by the cooler 10. Alternatively, the cooler 10 is formed with a first heat exchange air duct and a second heat exchange air duct, the first heat exchange air duct and the second heat exchange air duct are not in communication, the air passing through the regeneration area flows to the first fan 9 through the first heat exchange air duct, and another fan drives the air outside the clothes treatment apparatus to flow to the second heat exchange air duct. The flowing air in the second heat exchange air duct exchanges heat with the flowing air in the first heat exchange air duct, i.e., the flowing air in the second heat exchange air duct absorbs the heat of the flowing air in the first heat exchange air duct, to realize condensation dehumidification of the air passing through the regeneration area of the dehumidification turntable 7.

[0098] When the drying system comprises both the heat pump system and the desiccant system, the water collecting box 1 is arranged below the evaporator 6 of the heat pump system, and the liquid water condensed on the surface of the evaporator 6 can drop into the water collecting box 1. If the desiccant system also produces condensed water, the water collecting box 1 also collects the condensed water produced by the desiccant system. Please refer to Figure 3 , the carousel desiccant device comprises the heater 8, the first fan 9 and the cooler 10, and the desiccant system can produce condensed water on the surface of the cooler 10 when working. Please refer to Figure 4 , the carousel desiccant device comprises the heater 8, the first fan 9 and the flow channel, the heater 8 and the first fan 9 are arranged on the flow channel, and the air outside the clothes treatment equipment can flow to the regeneration area through the flow channel under the drive of the first fan 9, the air passing through the regeneration area can be discharged to the outside of the clothes treatment equipment through the airflow channel, and the heater 8 can heat the air flowing to the regeneration area. Since the air passing through the regeneration area is discharged to the outside of the clothes treatment equipment through the airflow channel, the desiccant system does not produce condensed water. Therefore, when the drying system comprises both the heat pump system and the desiccant system, and the desiccant system also produces condensed water, the water collecting box 1 also collects the condensed water produced by the desiccant system.

[0099] When the drying system comprises both the heat pump system and the desiccant system, in one embodiment, the desiccant carousel 7 is arranged between the evaporator 6 and the condenser 4, and the airflow passing through the evaporator 6 can flow to the condenser 4 through the adsorption area.

[0100] In this embodiment, the adsorption area of the desiccant carousel 7 is arranged between the evaporator 6 and the condenser 4, and the airflow passing through the evaporator 6 can flow to the condenser 4 through the adsorption area, that is, the air dehumidified by the evaporator 6 can be subjected to secondary dehumidification through the adsorption area of the desiccant carousel 7. When the drying system provided by this embodiment is applied to the clothes treatment equipment and the heat pump system and the desiccant system work simultaneously, please refer to Figure 3 , the flow direction of the circulating air in the clothes treatment equipment is as follows: the circulating air is heated to high-temperature dry air after passing through the condenser 4, then enters the drum 11 through the impeller 12 to take away the moisture on the clothes, flows to the evaporator 6 after passing through the filter screen 13, and flows to the adsorption area of the desiccant carousel 7 after being condensed by the evaporator 6, and then flows to the condenser 4 again after being dehumidified by the adsorption area of the desiccant carousel 7.

[0101] The working modes of the clothes treatment equipment provided by this embodiment include three modes, and the three working modes are a single heat pump system dehumidification mode, a single desiccant system dehumidification mode and a heat pump and desiccant system simultaneous working dehumidification mode. The single heat pump system dehumidification mode means that only the heat pump system works, the single desiccant system dehumidification mode means that only the desiccant system works, and the heat pump and desiccant system simultaneous working dehumidification mode means that the heat pump system and the desiccant system work simultaneously.

[0102] Specifically, when the single desiccant system dehumidification mode is adopted, when the humid air passes through the adsorption area of the dehumidification rotating disc 7, the adsorption area can adsorb the water in the air to achieve the effect of dehumidification; in addition, as described above, when the regeneration area of the dehumidification rotating disc 7 is regenerated and forms an adsorption area by rotation of the dehumidification rotating disc 7, the adsorption area has the heat provided by the rotating disc dehumidification device at this time, so that the adsorption area can have a heating effect on the air passing through it. Therefore, when the single desiccant system dehumidification mode is adopted, the clothes in the drum 11 can also achieve the effect of drying.

[0103] When the clothes treatment apparatus performs drying of the wet clothes once, a working mode can be operated during the drying once, such as only operating the single heat pump system dehumidification mode or only operating the heat pump and molecular sieve simultaneous working dehumidification mode; or, during the drying of the clothes once, the single heat pump system dehumidification mode and the heat pump and molecular sieve simultaneous working dehumidification mode can be operated respectively at different time periods.

[0104] For example, when the ambient temperature is relatively low, in order to improve the efficiency of the clothes treatment apparatus in drying the clothes, the clothes treatment apparatus can be controlled to operate the heat pump and molecular sieve simultaneous working dehumidification mode; when the ambient temperature is relatively high, in order to avoid the situation that the heat pump system compressor 3 stops working due to large working load, the clothes treatment apparatus can be controlled to operate the single heat pump system dehumidification mode.

[0105] In an embodiment, the clothes treatment apparatus further comprises a drying count device connected to the general controller of the clothes treatment apparatus, and the drying count device is used to detect the number of times of drying the clothes by the clothes treatment apparatus. The drying count device transmits the detected signal to the general controller. Specifically, the control process of the clothes treatment apparatus includes the following contents:

[0106] The general controller determines whether the number of times of drying the clothes by the clothes treatment apparatus is equal to N according to the signal transmitted by the drying count device;

[0107] If yes, the general controller determines whether the clothes treatment apparatus has completed drying the clothes;

[0108] If yes, the general controller determines whether the drain pump connected to the water accumulation box 1 is in an inoperative state;

[0109] If yes, the heating device is controlled to work, and heat is generated by the working of the heating device to evaporate the accumulated water in the water accumulation box 1.

[0110] In the above control process, after the heating device works once, the number of times of drying the clothes by the clothes treatment apparatus is accumulated again.

[0111] In one embodiment, the garment processing equipment further includes a water pump operation count device, which is connected to the main controller of the garment processing equipment. The water pump operation count device is used to detect the number of times the water pump connected to the water collection box operates. The drying count device transmits the detected signal to the main controller. Specifically, the control flow of the garment processing equipment includes the following:

[0112] The main controller determines whether the clothes drying equipment has finished drying the clothes;

[0113] If so, the main controller determines whether the drainage pump connected to the water collection box 1 is not in operation;

[0114] If so, the main controller determines whether the number of times the drainage pump operates is greater than n based on the signal transmitted by the pump operation count device.

[0115] If so, the heating device is controlled to work, and heat is generated by the heating device to evaporate the water in the water collection box 1.

[0116] In the above control process, the number of times the drain pump works will be recalculated after each operation of the heating device.

[0117] For a method of removing water from the water collection box 1 using the clothing processing device provided in any of the above embodiments, please refer to [link to relevant documentation]. Figure 5 It includes the following:

[0118] Determine whether the clothing processing equipment meets the conditions for heating the water collection box 1;

[0119] If so, the heating device is controlled to work, and heat is generated by the heating device to evaporate the water in the water collection box 1.

[0120] The method for removing water from the water collection box 1 provided in this embodiment can control the heating device to work when it is determined whether the clothing processing equipment meets the conditions for heating the water collection box 1. When the heating device works, it can generate heat, which can be used to evaporate the water in the water collection box 1, thereby keeping the water collection box 1 dry and reducing the growth of bacteria and the generation of odors.

[0121] Regarding the method for removing water from water collection box 1, for example, in a specific case:

[0122] Determine whether the clothing processing equipment has finished drying the clothes;

[0123] If so, determine whether the drain pump connected to the water collection box 1 is not in operation;

[0124] If so, the heating device is controlled to work, and heat is generated by the heating device to evaporate the water in the water collection box 1.

[0125] That is, in the present example, after the laundry treating apparatus dries the laundry each time (i.e., after the laundry treating apparatus dries the laundry for the first time), the laundry treating apparatus does not immediately power off, but first controls the heating device to operate to evaporate the water in the water accumulation box 1 in a state in which the water pump is determined to be inoperative, and then controls the heating device to stop operating when it is determined that the water in the water accumulation box 1 has been evaporated. At this time, the laundry treating apparatus indicates that the drying of the laundry is complete and powers off.

[0126] As to determining whether the water in the water accumulation box 1 has been evaporated, the specific determination method is as follows in one example:

[0127] determining whether the heating device has operated for a time T;

[0128] if so, determining that the water in the water accumulation box 1 has been evaporated;

[0129] As to determining whether the water in the water accumulation box 1 has been evaporated, the specific determination method is as follows in another example:

[0130] detecting the water in the water accumulation box 1;

[0131] if the detection indicates that there is still water, determining that the water in the water accumulation box 1 has not been evaporated;

[0132] if no water is detected, determining that the water in the water accumulation box 1 has been evaporated.

[0133] The above describes one specific example of the method of removing water from the water accumulation box 1, and in another specific example:

[0134] determining whether the number of times the laundry treating apparatus dries the laundry at present is equal to N, N being greater than or equal to 2;

[0135] if so, determining whether the laundry treating apparatus at present has completed drying the laundry;

[0136] if so, determining whether the water pump connected to the water accumulation box 1 is inoperative;

[0137] if so, controlling the heating device to operate to evaporate the water in the water accumulation box 1 by generating heat through the operation of the heating device.

[0138] determining whether the number of times the laundry treating apparatus dries the laundry at present is equal to N, i.e., determining whether to perform N times of drying the laundry, including the operation of drying the laundry being performed at present by the laundry treating apparatus.

[0139] That is, in the present example, the water in the water accumulation box 1 is treated when the number of times the laundry treating apparatus dries the laundry is equal to N. When it is determined that the water in the water accumulation box 1 has been evaporated, the control device controls the heating device to stop operating. The number of times the laundry treating apparatus dries the laundry is re-counted each time the heating device operates once.

[0140] As to the method for removing the water in the water accumulation box 1, in another specific example:

[0141] determining whether the clothes treating apparatus has completed drying the clothes;

[0142] if yes, determining whether the drain pump connected to the water accumulation box 1 is in a non-working state;

[0143] if yes, determining whether the number of times the drain pump works is greater than n, wherein n is greater than or equal to 1;

[0144] if yes, controlling the heating device to work to generate heat to evaporate the water in the water accumulation box 1.

[0145] That is, in the present example, the working condition of the heating device is controlled according to the number of times the drain pump works. When the number of times the drain pump works is greater than n, the clothes treating apparatus does not immediately power off after the drying of the clothes is completed, but the control device controls the heating device to work to evaporate the water in the water accumulation box 1. After the heating device works each time, the number of times the drain pump works is accumulated again.

[0146] Please refer to Figure 6 , as to the method for removing the water in the water accumulation box 1, in another specific example:

[0147] determining whether the clothes treating apparatus has completed drying the clothes;

[0148] if yes, determining whether the drain pump connected to the water accumulation box 1 is in a non-working state:

[0149] if yes, detecting whether there is water in the water accumulation box 1;

[0150] if yes, controlling the heating device to work to generate heat to evaporate the water in the water accumulation box 1.

[0151] That is, in the present example, the working condition of the heating device is controlled according to whether there is water in the water accumulation box 1. Specifically, the water accumulation box 1 is provided with a water detection device, and the water detection device is connected to the control device. The water detection device is used to detect the water in the water accumulation box 1.

[0152] The above only describes preferred examples of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
