Technical Field

[0001] This application belongs to the field of household appliance technology, and in particular relates to a drying system, clothing processing equipment and method for clothing processing equipment. Background Technology

[0002] With the improvement of living standards, heat pump dryers are becoming increasingly popular among consumers. Heat pump dryers are based on heat pump technology, which evaporates the moisture in washed clothes instantly to dry them. Heat pump dryers have certain advantages in energy saving, but they are lacking in drying speed, especially when the ambient temperature is relatively low or high. Summary of the Invention

[0003] The purpose of this application is to provide a drying system, clothing processing equipment and method for clothing processing equipment, so as to solve the technical problem of insufficient drying speed of heat pump dryers in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] This application provides a drying system for a garment processing device, comprising:

[0006] A heat pump system includes a compressor, a condenser, a throttling element, and an evaporator connected in sequence.

[0007] The dehumidification system includes a dehumidification disc and a disc dehumidification device. The dehumidification disc has an adsorption zone and a regeneration zone. The dehumidification disc is located between the evaporator and the condenser. The airflow passing through the evaporator can flow to the condenser through the adsorption zone. The disc dehumidification device can generate hot air and blow it to the regeneration zone.

[0008] In some implementations, the rotary dehumidifier includes a heater, a first fan, and a cooler. Driven by the first fan, the air heated by the heater flows to the regeneration zone, and the airflow in the regeneration zone is dehumidified by the cooler before flowing to the heater.

[0009] In some implementations, the cooler is a water-cooled heat exchanger, and water pipes are installed inside the cooler.

[0010] In some implementations, the rotary dehumidifier includes a water inlet pipe; one end of the water inlet pipe is connected to the water inlet of the cooler, and the other end of the water inlet pipe is used to connect to a water valve outside the garment processing equipment;

[0011] Alternatively, one end of the water inlet pipe is connected to the water inlet of the cooler, and the other end of the water inlet pipe is connected to the water collector located below the evaporator, and a water pump is installed on the water inlet pipe.

[0012] Alternatively, the water inlet pipe includes a first water inlet pipe section, a second water inlet pipe section, and a third water inlet pipe section. One end of the first water inlet pipe section, the second water inlet pipe section, and the third water inlet pipe section are connected through a water inlet valve body. The other end of the first water inlet pipe section is connected to the water inlet of the cooler. The other end of the second water inlet pipe section is connected to the water collector. A water pump is installed on the second water inlet pipe section. The other end of the third water inlet pipe section is used to connect to a water valve outside the clothing processing equipment.

[0013] In some implementations, the rotary dehumidifier includes an outlet pipe, which consists of a main pipe section and branch pipe sections. A sewage pump is installed on the main pipe section, and one end of the main pipe section is connected to the outlet of the cooler.

[0014] The other end of the main pipe is connected to a branch pipe section, which is used to draw water to the outside of the garment processing equipment or to draw water to the water box on the garment processing equipment.

[0015] Alternatively, a water outlet valve body is provided at the other end of the main pipe section, and two branch pipe sections are connected to the water outlet valve body. The two branch pipe sections are used to draw water to the outside of the clothing processing equipment and to draw water to the water box on the clothing processing equipment, respectively.

[0016] Alternatively, the other end of the main pipe is equipped with a water outlet valve body, which is connected to two or more branch pipe sections. One branch pipe section is used to draw water to the water collector below the evaporator, while the other branch pipe sections are used to draw water to the outside of the clothing processing equipment or to draw water to the water box on the clothing processing equipment.

[0017] A garment processing device includes a drying system as provided in any of the above technical solutions.

[0018] In some implementations, the garment processing equipment also includes a control device, to which the heat pump system and the moisture absorption and dehumidification system are connected. The control device can control the heat pump system to work alone, control the moisture absorption and dehumidification system to work alone, and control the heat pump system and the moisture absorption and dehumidification system to work simultaneously.

[0019] In some implementations, the garment processing equipment also includes a drum temperature detection sensor connected to a control device. The drum temperature detection sensor is used to detect the temperature inside the drum of the garment processing equipment, and the control device controls the working state of the moisture absorption and dehumidification system based on the signal detected by the drum temperature detection sensor.

[0020] In some implementations, the garment processing equipment also includes an ambient temperature sensor connected to a control device. The ambient temperature sensor is used to detect the ambient temperature, and the control device controls the operating status of the moisture absorption and dehumidification system based on the signal detected by the ambient temperature sensor.

[0021] In some implementations, the garment processing equipment also includes a timing device connected to a control device. The timing device is used to time the working time of the heat pump system, and the control device controls the working status of the moisture absorption and dehumidification system based on the signal fed back by the timing device.

[0022] A method for drying clothes using a drying system provided by any of the above technical solutions includes the following:

[0023] Determine whether the conditions for simultaneous operation of the heat pump system and the moisture absorption and dehumidification system are met;

[0024] If so, then control the heat pump system and the dehumidification system to work simultaneously;

[0025] If not, the dehumidification system will stop working.

[0026] In some implementations, when the heat pump system is in operation: it is determined whether the temperature of the drum in the clothing processing equipment is higher than the preset temperature. If so, the moisture absorption and dehumidification system is controlled to stop working; otherwise, the moisture absorption and dehumidification system is controlled to work.

[0027] In some implementations, when the heat pump system is in operation: it is determined whether the running time of the heat pump system since startup is less than t1. If it is less than t1, the dehumidification system is controlled to work. If it is not less than t1, the dehumidification system is controlled to stop working.

[0028] Determine if the time remaining before the end of operation of the heat pump system is less than t2. If it is less than t2, control the dehumidification system to work. If it is not less than t2, control the dehumidification system to stop working.

[0029] In some implementations, when the heat pump system is in operation: it determines whether the ambient temperature is lower than a first preset temperature value; if so, it controls the dehumidification system to operate.

[0030] In some implementations, when the heat pump system is in operation: if the ambient temperature is higher than a second preset temperature value, then the heat pump system is controlled to stop working and the dehumidification system is controlled to work; otherwise, the heat pump system is controlled to continue working.

[0031] In some implementations, it is determined whether the conditions for the dehumidification system to operate independently are met; if they are met, the dehumidification system is controlled to operate independently.

[0032] The beneficial effects of this application are as follows: When the heat pump system and the dehumidification system are working simultaneously, the drying system provided in this embodiment can not only dehumidify the air passing through the drum through the evaporator, but also perform secondary dehumidification of the air passing through the drum through the adsorption zone of the dehumidification disc. This reduces the moisture in the air flowing towards the condenser, making it easier for the air to be heated by the condenser and then enter the drum to remove more moisture from the clothes, thereby improving the drying speed of the clothing processing equipment in low-temperature environments. In addition, when the ambient temperature is relatively high, only the dehumidification system can be controlled to work, and dehumidification can be performed by the dehumidification system, avoiding the shutdown of the heat pump system under high-temperature conditions, which would affect the drying speed of the clothing processing equipment.

Specifically, the use of words such as "in one embodiment," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner.

[0049] Please see Figure 1 This is a diagram of an existing heat pump dryer system. The heat pump system operates as follows: High-temperature, high-pressure gaseous refrigerant releases heat in condenser 2, becoming high-pressure, medium-temperature liquid refrigerant. It then passes through throttling element 3 to cool and depressurize into low-temperature, low-pressure gas-liquid two-phase refrigerant. Entering condenser 2, it absorbs heat and vaporizes into medium-temperature, low-pressure gaseous refrigerant, which is then compressed by compressor 1 into high-temperature, high-pressure gaseous refrigerant. The airflow direction within the dryer is as follows: After passing through condenser 2, the air is heated to high-temperature dry air. It then passes through impeller 14 into drum 15, carrying away moisture from the clothes. After passing through evaporator 4, the air is cooled, condenses into water, and flows back to condenser 2 for reheating, circulating continuously. The liquid water condensed on the surface of evaporator 4 falls into water collector 12 below evaporator 4.

[0050] When the ambient temperature is low, the evaporation temperature of the heat pump system decreases (evaporation temperature refers to the boiling point of the refrigerant in the evaporator). This decrease in evaporation temperature leads to a drop in the suction pressure of compressor 1, resulting in a decrease in the heating capacity of the heat pump system. This, in turn, affects the removal of moisture from clothes by the circulating airflow through the drum 15. Therefore, the drying speed of the dryer is slow in low-temperature environments. When the ambient temperature is high, the compressor 1 of the heat pump system operates under heavy load and may shut down, resulting in a slow drying speed.

[0051] To address the above issues, this embodiment provides a drying system for a clothing processing device. The clothing processing device can be a dryer and includes a heat pump system and a moisture absorption and dehumidification system.

[0052] Please see Figure 2 The heat pump system includes a compressor 1, a condenser 2, a throttling element 3, and an evaporator 4 connected in sequence. The heat pump system works as follows: the high-temperature and high-pressure gaseous refrigerant releases heat through the condenser 2 and becomes a high-pressure and medium-temperature liquid refrigerant. It is then cooled and depressurized by the throttling element 3 to become a low-temperature and low-pressure gas-liquid two-phase refrigerant. After absorbing heat in the evaporator 4, it enters the compressor 1 and is compressed into a high-temperature and high-pressure gaseous refrigerant.

[0053] The moisture absorption and dehumidification system includes a dehumidification disc 5 and a disc dehumidification device. Please refer to [link / reference]. Figure 2The diagram shows the dehumidification turntable 5, which is located between the evaporator 4 and the condenser 2. The dehumidification turntable 5 is used to dehumidify the air passing through it.

[0054] Specifically, the dehumidifying disc 5 has an adsorption zone and a regeneration zone. When humid air passes through the adsorption zone of the dehumidifying disc 5, the moisture-absorbing material on the disc adsorbs the moisture. The regeneration zone is exposed to hot air, meaning that hot air generated by the dehumidifying device blows onto the regeneration zone, causing the moisture on the moisture-absorbing material to evaporate. The process of the dehumidifying disc 5 adsorbing moisture is called adsorption, and the process of moisture evaporation is called regeneration. After regeneration, the regeneration zone of the dehumidifying disc 5 rotates to form an adsorption zone, allowing it to continuously adsorb moisture from the air passing through. Furthermore, when the regeneration zone of the dehumidifying disc 5 rotates to form an adsorption zone, the adsorption zone receives heat from the dehumidifying device, thus heating the air passing through it.

[0055] Regarding the moisture-absorbing material of the dehumidifying turntable 5, preferably, the moisture-absorbing material on the dehumidifying turntable 5 is a molecular sieve.

[0056] In this embodiment, the adsorption zone of the dehumidification disc 5 is located between the evaporator 4 and the condenser 2. The airflow passing through the evaporator 4 can flow to the condenser 2 through the adsorption zone. That is, after the air is dehumidified by the evaporator 4, it can be dehumidified again through the adsorption zone of the dehumidification disc 5.

[0057] When the drying system provided in this embodiment is applied to a clothing processing device and the heat pump system and the moisture absorption and dehumidification system operate simultaneously, please refer to [link to relevant documentation]. Figure 2 The airflow direction within the garment processing equipment is as follows: After passing through the condenser 2, the circulating air is heated into high-temperature dry air. It then enters the drum 15 through the impeller 14, carrying away moisture from the clothes. After passing through the filter 17, the air flows to the evaporator 4. After being cooled and condensed into water in the evaporator 4, the air flows to the adsorption zone of the dehumidification disc 5. After being dehumidified in the adsorption zone of the dehumidification disc 5, it flows back to the condenser 2 for heating, and the cycle repeats continuously. When the ambient temperature is relatively low, the heat pump system and the dehumidification system of the drying system can be controlled to work simultaneously to increase the drying speed of the garment processing equipment.

[0058] When the ambient temperature is high, only the moisture absorption and dehumidification system can be controlled to operate, and dehumidification can be carried out by the moisture absorption and dehumidification system to avoid the heat pump system from shutting down under high temperature conditions, which would affect the drying speed of the clothing processing equipment.

[0059] Regarding the filter screen 17 installed at the front end of the airflow of the evaporator 4, the airflow entering the cylinder 15 carries away the moisture on the clothes and also carries away the lint on the clothes. The filter screen 17 has the function of filtering the lint in the air to prevent a large amount of lint from adhering to the surface of the evaporator 4 and affecting the heat exchange between the evaporator 4 and the air.

[0060] The drying system provided in this embodiment can not only dehumidify the air passing through the drum 15 through the evaporator 4, but also perform secondary dehumidification of the air passing through the drum 15 through the adsorption zone of the dehumidification turntable 5. This reduces the moisture in the air flowing towards the condenser 2, making it easier for the air to carry away more moisture from the clothes after being heated by the condenser 2 and entering the drum 15. This improves the drying speed of the clothing processing equipment in low-temperature environments. When the ambient temperature is relatively high, only the moisture absorption and dehumidification system can be controlled to operate, and dehumidification can be performed by the moisture absorption and dehumidification system. This avoids the heat pump system from shutting down under high-temperature conditions, which would affect the drying speed of the clothing processing equipment.

[0061] For details regarding the specific structure of the rotary dehumidifier, please refer to one embodiment. Figure 2 The rotary dehumidifier includes a heater 6, a first fan 7, and a cooler 8. The heater 6 is used to heat the air passing through it, the cooler 8 is used to dehumidify the air passing through it, and the first fan 7 is used to drive the airflow to circulate between the heater 6, the cooler 8, and the regeneration zone of the dehumidification rotary disc 5.

[0062] The first fan 7 can be located between the heater 6 and the cooler 8, or the first fan 7 can also be located between the cooler 8 and the regeneration zone of the dehumidification disc 5. Please refer to [link / reference]. Figure 2 This illustrates that the first fan 7 can be located between the heater 6 and the cooler 8. When the first fan 7 is working, the flow direction of the circulating air is as follows: the medium-temperature, low-humidity gas after passing through the cooler 8 flows to the heater 6 through the first fan 7. The heater 6 heats the air passing through it into high-temperature dry air, which then enters the regeneration zone of the dehumidification disc 5, carrying away the moisture in the regeneration zone. The air then flows to the cooler 8 to condense into liquid water, becoming medium-temperature, low-humidity gas that continues to circulate. The liquid water condensed on the surface of the cooler 8 falls into the water collector 12.

[0063] Preferably, the heater 6 is an electric heating element.

[0064] The rotary dehumidifier provided in this embodiment includes a heater 6, a first fan 7, and a cooler 8, which enables the rotary dehumidifier to not only provide dry hot air to the regeneration zone of the dehumidification rotary disc 5, but also has a simple structure.

[0065] In an example of a rotary dehumidification device including a heater 6, a first fan 7, and a cooler 8, in one embodiment, the cooler 8 is a water-cooled heat exchanger and has water pipes installed inside it.

[0066] The cooler 8 has an inlet and an outlet, both of which are connected to a water pipe inside the cooler 8. Water can enter the water pipe through the inlet and exit through the outlet. The water flowing inside the cooler 8 can exchange heat with the air passing over its surface. The water in the cooler 8 absorbs heat from the air, causing the air to cool down and condense into condensate, thus enabling the cooler 8 to dehumidify the air passing through the regeneration zone of the dehumidification disc 5.

[0067] The cooler 8 provided in this embodiment uses a water-cooled heat exchanger, which is low in cost and can reduce the cost of clothing processing equipment.

[0068] Regarding the water source for the cooler 8, in one embodiment, the rotary dehumidifier includes a water inlet pipe 9, one end of which is connected to the water inlet of the cooler 8; the other end of the water inlet pipe 9 is connected to a water valve outside the garment processing equipment. That is, in this embodiment, the water source for the cooler 8 originates from outside the garment processing equipment.

[0069] In this embodiment, an inlet valve body 18 is provided on the water inlet pipe 9. The water inlet valve body 18 is connected to the control device of the drying system, and the control device can control the opening and closing of the water inlet valve body 18. Specifically, for a clothing processing device equipped with the drying system provided in this embodiment, the water inlet pipe 9 is connected to a water valve. When using the clothing processing device, the water valve is manually opened. When the dehumidification system needs to work, the control device controls the water inlet valve body 18 to open, so that the tap water flowing out of the water valve can flow to the cooler 8 through the water inlet pipe 9. When the dehumidification system does not need to work, the control device controls the water inlet valve body 18 to close.

[0070] In this embodiment, the water source for the cooler 8 is tap water. Since tap water has a low temperature, the cooler 8 can effectively dehumidify the air passing through it.

[0071] Regarding the water source for the cooler 8, in another embodiment, the rotary dehumidifier includes a water inlet pipe 9, one end of which is connected to the water inlet of the cooler 8, and the other end of which is connected to a water collector 12 located below the evaporator 4, and a water pump 10 is installed on the water inlet pipe 9.

[0072] When the water pump 10 starts, the water in the water collector 12 can flow to the cooler 8 through the water inlet pipe 9. That is, in this embodiment, the water in the cooler 8 comes from inside the clothing processing equipment. The condensate from the water collector 12 flows into the cooler 8 and exchanges heat with the air passing over the surface of the cooler 8.

[0073] During the operation of the garment processing equipment, condensate water falling from the evaporator 4 and cooler 8 continuously falls into the water collector 12. In one example, a low water level detection sensor and a high water level detection sensor can be installed in the water collector 12. Along the height direction of the water collector 12, the height of the high water level detection sensor is greater than that of the low water level detection sensor. The low water level detection sensor, the high water level detection sensor, and the water pump 10 are all connected to the control device of the drying system. The start of the water pump 10 depends on the water level in the water collector 12. Specifically, when the high water level detection sensor detects a water level, it indicates that there is a lot of water in the water collector 12, and the control device can control the water pump 10 to start. At the same time, it also controls the heater 6 and the first fan 7 to work, so that the dehumidification system can perform secondary dehumidification of the air in the drum 15. When the low water level detection sensor does not detect a water level, it indicates that there is a little water in the water collector 12. At this time, the control device controls the water pump 10, the heater 6, and the first fan 7 not to start.

[0074] During the operation of the clothing processing equipment, condensate water falling from the evaporator 4 and cooler 8 continuously falls into the water collector 12. In another example, the rotation speed of the water pump 10 can be controlled so that, in scenarios requiring dehumidification using a moisture absorption and dehumidification system, the water pump 10 can remain operational to perform secondary dehumidification of the air in the drum 15 through the moisture absorption and dehumidification system. Specifically, for clothing processing equipment equipped with the drying system provided in this embodiment, a low water level detection sensor and a high water level detection sensor can be installed in the water collector 12. Along the height direction of the water collector 12, the height of the high water level detection sensor is greater than the height of the low water level detection sensor. In scenarios requiring dehumidification using a moisture absorption and dehumidification system, when the high water level detection sensor detects a water level, it indicates that there is a large amount of water in the water collector 12. The rotation speed of the water pump 10 can be increased so that the amount of water pumped out of the water collector 12 per unit time is greater than the amount of water falling from the evaporator 4 and cooler 8 into the water collector 12 per unit time. The water level in the collector 12 is controlled to decrease. When the high water level sensor does not detect the water level but the low water level sensor detects the water level, the speed of the water pump 10 can be reduced so that the amount of water pumped out of the collector 12 by the water pump 10 per unit time is equal to the amount of water falling from the evaporator 4 and the cooler 8 into the collector 12 per unit time. When the low water level sensor does not detect the water level, it means that the water level in the collector 12 is low. The speed of the water pump 10 can be further reduced so that the amount of water pumped out of the collector 12 by the water pump 10 per unit time is less than the amount of water falling from the evaporator 4 and the cooler 8 into the collector 12 per unit time.

[0075] In this embodiment, the condensate from the water collector 12 flows into the cooler 8 and exchanges heat with the air passing over the surface of the cooler 8, thus avoiding the need to connect to an external water valve, which would restrict the placement of the clothing processing equipment indoors.

[0076] Regarding the water inlet source of cooler 8, in one embodiment, please refer to... Figure 3 The rotary dehumidifier includes a water inlet pipe 9, which comprises a first water inlet pipe section 901, a second water inlet pipe section 902, and a third water inlet pipe section 903. One end of each of these sections is connected via a water inlet valve body 18. The other end of the first water inlet pipe section 901 is connected to the water inlet of the cooler 8, and the other end of the second water inlet pipe section 902 is connected to a water collector 12. A water pump 10 is mounted on the second water inlet pipe section 902. The other end of the third water inlet pipe section 903 is connected to a water valve outside the clothing processing equipment. In this embodiment, the water supply to the cooler 8 can originate not only from outside the clothing processing equipment but also from the condensate collected by the water collector 12.

[0077] In scenarios where dehumidification using a moisture absorption and dehumidification system is required, the condensate in the water collector 12 can be used first. When the condensate in the water collector 12 is insufficient, external water from the clothing processing equipment is controlled to enter the cooler 8. Specifically, for clothing processing equipment equipped with the drying system provided in this embodiment, the third water inlet pipe section 903 is connected to a water valve. A low water level detection sensor and a high water level detection sensor can be installed in the water collector 12. Along the height direction of the water collector 12, the height of the high water level detection sensor is greater than the height of the low water level detection sensor. In scenarios where dehumidification using a moisture absorption and dehumidification system is required, when the high water level detection sensor detects a water level, it indicates that there is a large amount of water in the water collector 12. The control device controls the water inlet valve body 18 to connect the first water inlet pipe section 901 and the second water inlet pipe section 902. The first water inlet pipe section 901 and the third water inlet pipe section 902 are connected. When water pipe section 903 is blocked, the water pump 10 is started. At the same time, the heater 6 and the first fan 7 are also started, so that the dehumidification system can perform secondary dehumidification of the air in the cylinder 15. When the low water level detection sensor does not detect the water level, it means that the water in the water collector 12 is low. At this time, the control device controls the water pump 10 not to start. The control device controls the water inlet valve body 18 to block the first water inlet pipe section 901 and the second water inlet pipe section 902. The first water inlet pipe section 901 and the third water inlet pipe section 903 are connected, so that the water flowing out of the water valve can flow to the cooler 8 through the first water inlet pipe section 901 and the third water inlet pipe section 903.

[0078] In this embodiment, it is possible not only to utilize the condensate collected by the water collector 12, but also to ensure the normal operation of the dehumidification system.

[0079] Regarding the drainage of the cooler 8, in one embodiment, the rotary dehumidifier includes a water outlet pipe 11, which includes a main pipe section 1101 and a branch pipe section 1102. A sewage pump 20 is installed on the main pipe section 1101. One end of the main pipe section 1101 is connected to the water outlet of the cooler 8.

Alternatively, a branch pipe section 1102 can be connected to the water tank 13 to allow water to be drawn into the water tank 13 via the outlet pipe 11. When the water tank 13 is full, the user can remove the water tank 13, empty the water, and then reinsert it into the garment processing equipment.

[0082] Regarding the drainage of the cooler 8, in another embodiment, the rotary dehumidifier includes a water outlet pipe 11, which comprises a main pipe section 1101 and branch pipe sections 1102. A sewage pump 20 is installed on the main pipe section 1101. One end of the main pipe section 1101 is connected to the water outlet of the cooler 8, and the other end of the main pipe section 1101 is provided with a water outlet valve body 19. Two branch pipe sections 1102 are connected to the water outlet valve body 19, which are used to draw water to the outside of the clothing processing equipment and to draw water to the water box 13 on the clothing processing equipment, respectively. By controlling the water outlet valve body 19, water can be drawn to the outside of the clothing processing equipment or to the water box 13 on the clothing processing equipment when the sewage pump 20 is started.

[0083] In this embodiment, two drainage methods for the cooler 8 are provided so that the user can choose the appropriate drainage method for the cooler 8 according to the user's needs.

[0084] Regarding the drainage of the cooler 8, in another embodiment, the rotary dehumidifier includes a water outlet pipe 11, which includes a main pipe section 1101 and branch pipe sections 1102. A sewage pump 20 is installed on the main pipe section 1101. One end of the main pipe section 1101 is connected to the water outlet of the cooler 8, and the other end of the main pipe section 1101 is provided with a water outlet valve body 19. Two or more branch pipe sections 1102 are connected to the water outlet valve body 19. One branch pipe section 1102 is used to draw water to the water collector 12 below the evaporator 4, and the other branch pipe sections 1102 are used to draw water to the outside of the clothing processing equipment or to draw water to the water box 13 on the clothing processing equipment.

[0085] For example, two branch pipe sections 1102 are connected to the outlet valve body 19. One branch pipe section 1102 is used to draw water to the water collector 12 below the evaporator 4, and the other branch pipe section 1102 is used to draw water to the outside of the laundry processing equipment. Alternatively, two branch pipe sections 1102 are connected to the outlet valve body 19. One branch pipe section 1102 is used to draw water to the water collector 12 below the evaporator 4, and the other branch pipe section 1102 is used to draw water to the water box 13 on the laundry processing equipment. Or, please see Figure 5 The outlet valve body 19 is connected to three branch pipe sections 1102. One branch pipe section 1102 is used to draw water to the water collector 12 below the evaporator 4. Of the other two branch pipe sections 1102, one branch pipe section 1102 is used to draw water to the outside of the clothing processing equipment, and the other branch pipe section 1102 is used to draw water to the water box 13 on the clothing processing equipment.

[0086] Taking the outlet valve body 19 as an example, with two branch pipe sections 1102 connected on it, one branch pipe section 1102 being used to draw water to the water collector 12 below the evaporator 4 and the other branch pipe section 1102 being used to draw water to the outside of the clothing processing equipment, when one end of the inlet pipe 9 is connected to the water inlet of the cooler 8 and the other end of the inlet pipe 9 is connected to the water collector 12 located below the evaporator 4, and a water pump 10 is installed on the inlet pipe 9, if the water volume in the water collector 12 is insufficient, the outlet valve body 19 can be controlled to discharge the water in the cooler 8 to the water collector 12; when the water volume in the water collector 12 is sufficient, the outlet valve body 19 can be controlled to discharge the water in the cooler 8 to the outside of the clothing processing equipment. Specifically, a low water level detection sensor and a high water level detection sensor can be installed inside the water collector 12. Along the height direction of the water collector 12, the height of the high water level detection sensor is greater than the height of the low water level detection sensor. In scenarios where a dehumidification system is required, when the high water level detection sensor detects a water level, it indicates that there is a large amount of water in the water collector 12. The control device can then control the water pump 10 to start, and simultaneously control the heater 6 and the first fan 7 to operate, as well as control the outlet valve 19, so that the water in the cooler 8 is discharged outside the clothing processing equipment. When the low water level detection sensor does not detect a water level, it indicates that there is a small amount of water in the water collector 12. In this case, the outlet valve 19 is controlled to discharge the water in the cooler 8 into the water collector 12.

[0087] In this embodiment, one of the branch pipe sections 1102 is set to draw water to the water collector 12 below the evaporator 4, so as to ensure the normal operation of the moisture absorption and dehumidification system.

[0088] This embodiment provides a garment processing device, including the drying system of the garment processing device provided in any of the above embodiments. The drying system includes a heat pump system and a moisture absorption and dehumidification system. The heat pump system includes a compressor 1, a condenser 2, a throttling element 3, and an evaporator 4 connected in sequence. The moisture absorption and dehumidification system includes a dehumidification turntable 5 and a turntable dehumidification device. The dehumidification turntable 5 has an adsorption zone and a regeneration zone. The dehumidification turntable 5 is disposed between the evaporator 4 and the condenser 2. The airflow passing through the evaporator 4 can flow to the condenser 2 through the adsorption zone. The turntable dehumidification device can generate hot air and blow it to the regeneration zone.

[0089] The clothing processing equipment provided in this embodiment can not only dehumidify the air passing through the drum 15 through the evaporator 4, but also perform secondary dehumidification of the air passing through the drum 15 through the adsorption zone of the dehumidification turntable 5. This reduces the moisture in the air flowing towards the condenser 2, making it easier for the air to be heated by the condenser 2 before entering the drum 15 and carrying away more moisture from the clothes, thus improving the drying speed of the clothing processing equipment. In addition, when the regeneration zone of the dehumidification turntable 5 is regenerated and forms an adsorption zone by rotating the dehumidification turntable 5, the adsorption zone has the heat provided by the turntable dehumidification device, which can heat the air passing through it, thereby increasing the air temperature and thus improving the drying speed of the clothing processing equipment to a certain extent.

[0090] In one embodiment, the garment processing device includes a water tank 13 and a water collector 12 disposed below the evaporator 4 of the drying system, wherein the water capacity of the water tank 13 is greater than the water capacity of the water collector 12.

[0091] In this embodiment, when one end of the water inlet pipe 9 is connected to the water inlet of the cooler 8, and the other end of the water inlet pipe 9 is connected to the water collector 12 located below the evaporator 4, and a water pump 10 is installed on the water inlet pipe 9, please refer to [link to relevant documentation]. Figure 6 The inlet valve body 18 can be positioned between the water pump 10 and the cooler 8. Simultaneously, the inlet valve body 18 is connected to a water box connecting pipe 21 and a drain pipe 16. The water box connecting pipe 21 is connected to the water box 13, and the drain pipe 16 is used to discharge water from the water collector 12 outside the clothing processing equipment. When the water pump 10 starts, the inlet valve body 18 can be controlled to pump water from the water collector 12 to the cooler 8, to the water box 13, or to the drain pipe. For example, when only the heat pump system of the drying system needs to operate and the dehumidification system does not need to operate, the water from the water collector 12 can be pumped to the water box 13 or to the drain pipe.

[0092] In this embodiment, when the water outlet pipe 11 has a branch pipe section 1102 for directing water from the cooler 8 to the outside of the clothing processing equipment, the branch pipe section 1102 is connected to the drain pipe 16 and forms a drain outlet for connecting to the floor drain.

[0093] In this embodiment, the water inlet pipe 9 includes a first water inlet pipe section 901, a second water inlet pipe section 902, and a third water inlet pipe section 903. One end of each of these sections is connected via a water inlet valve body 18. The other end of the first water inlet pipe section 901 is connected to the water inlet of the cooler 8, and the other end of the second water inlet pipe section 902 is connected to the water collector 12. A water pump 10 is installed on the second water inlet pipe section 902. The other end of the third water inlet pipe section 903 is used to connect to a water valve outside the clothing processing equipment. For an example, please refer to [link to example description]. Figure 7 A control valve 22 can be installed on the second water inlet pipe section 902. The control valve 22 is located between the water inlet valve body 18 and the water pump 10. A water box connecting pipe 21 and a drain pipe 16 are connected to the control valve 22. The water box connecting pipe 21 is connected to the water box 13. The drain pipe 16 is used to discharge the water in the water collector 12 out of the clothing processing equipment.

[0094] In one embodiment, the garment processing equipment further includes a control device, and the heat pump system and the moisture absorption and dehumidification system are both connected to the control device. The control device can control the heat pump system to work alone, control the moisture absorption and dehumidification system to work alone, and control the heat pump system and the moisture absorption and dehumidification system to work simultaneously.

[0095] The clothing processing equipment provided in this embodiment has three operating modes: a single heat pump system dehumidification mode, a single moisture absorption and dehumidification system dehumidification mode, and a simultaneous heat pump and dehumidification wheel dehumidification mode. The single heat pump system dehumidification mode means only the heat pump system operates; the single moisture absorption and dehumidification system dehumidification mode means only the moisture absorption and dehumidification system operates; and the simultaneous heat pump and dehumidification wheel dehumidification mode means both the heat pump system and the moisture absorption and dehumidification system are operating simultaneously.

[0096] Specifically, when using the single moisture absorption and dehumidification system in dehumidification mode, when humid air passes through the adsorption zone of the dehumidification disc 5, the adsorption zone can adsorb the moisture in the air, achieving the dehumidification effect. In addition, as mentioned above, when the regeneration zone of the dehumidification disc 5 is regenerated and forms an adsorption zone by rotating the dehumidification disc 5, the adsorption zone has the heat provided by the disc dehumidification device, which allows the adsorption zone to heat the air passing through it. Therefore, when using the single moisture absorption and dehumidification system in dehumidification mode, it can also achieve the effect of drying clothes inside the drum 15.

[0097] When the clothing processing equipment dries wet clothes, it can operate in one working mode during the drying process. For example, it can operate in a single heat pump system dehumidification mode or in a heat pump and rotor dehumidification mode that works simultaneously. Alternatively, during the drying process, it can operate in a single heat pump system dehumidification mode or a heat pump and rotor dehumidification mode at different time periods.

[0098] For example, when the ambient temperature is low, in order to improve the drying efficiency of the clothing processing equipment, the clothing processing equipment can be controlled to operate in a dehumidification mode where the heat pump and the dehumidifier work simultaneously; when the ambient temperature is high, in order to avoid the heat pump system compressor 1 from shutting down due to heavy workload, the clothing processing equipment can be controlled to operate in a single heat pump system dehumidification mode.

[0099] In this embodiment, the clothing processing device can automatically determine the operating mode; or / and, three operation keys can be set on the clothing processing device, which correspond to the high-efficiency dehumidification operation key, the medium-efficiency dehumidification operation key, and the low-efficiency dehumidification operation key, respectively. When the user presses the high-efficiency dehumidification operation key, the clothing processing device operates in the dehumidification mode where the heat pump and the dehumidifier work simultaneously; when the user presses the medium-efficiency dehumidification operation key, the clothing processing device operates in the dehumidification mode of a single heat pump system; when the user presses the low-efficiency dehumidification operation key, the clothing processing device operates in the dehumidification mode of a single moisture absorption and dehumidification system.

[0100] In this embodiment, the clothing processing equipment is configured to include three working modes, so that the clothing processing equipment can operate in different working modes according to different conditions.

[0101] In one embodiment, the garment processing equipment further includes a drum temperature detection sensor connected to a control device. The drum temperature detection sensor is used to detect the temperature inside the drum 15 of the garment processing equipment, and the control device controls the working state of the moisture absorption and dehumidification system based on the signal detected by the drum temperature detection sensor.

[0102] Specifically, when the clothing processing equipment dries the clothes in the drum 15, the drum temperature detection sensor detects the temperature in the drum 15 in real time and transmits the detected temperature signal to the control device. When the control device determines that the temperature of the drum 15 is lower than the preset value, for example, the preset value is 65℃, it controls the heat pump system and the moisture absorption and dehumidification system to work simultaneously; when the control device determines that the temperature of the drum 15 is not lower than the preset value, it controls only the heat pump system to work.

[0103] In this embodiment, the working state of the moisture absorption and dehumidification system is determined based on the temperature inside the cylinder 15, which achieves both rapid drying of clothes and energy saving.

[0104] In one embodiment, the garment processing equipment further includes an ambient temperature sensor connected to a control device. The ambient temperature sensor is used to detect the ambient temperature, and the control device controls the operating status of the moisture absorption and dehumidification system and the heat pump system based on the signal detected by the ambient temperature sensor.

[0105] Specifically, when the clothing processing equipment dries the clothes in the drum 15, the ambient temperature detection sensor detects the temperature of the environment in which the clothing processing equipment is located in real time and transmits the detected temperature signal to the control device. When the control device determines that the ambient temperature is lower than the first preset ambient temperature value, it controls the heat pump system and the moisture absorption and dehumidification system to work simultaneously; when the control device determines that the ambient temperature is not lower than the first preset ambient temperature value, it controls only the heat pump system to work.

[0106] As mentioned earlier, the drying speed of a clothes dryer is low when the ambient temperature is relatively low. In this embodiment, when a low ambient temperature is detected, the heat pump system and the moisture absorption and dehumidification system can be controlled to work simultaneously to increase the drying speed of the clothes processing equipment.

[0107] Specifically, when the clothing processing equipment dries the clothes in the drum 15, the ambient temperature detection sensor detects the temperature of the environment in which the clothing processing equipment is located in real time and transmits the detected temperature signal to the control device. When the control device determines that the ambient temperature is higher than the second preset ambient temperature value, it controls the dehumidification system to work.

[0108] When the ambient temperature is high, the heat pump system compressor 1 will be under heavy load and may shut down. Therefore, if the ambient temperature is higher than a second preset temperature value, the heat pump system can be controlled to stop working, and the dehumidification system can be controlled to work to perform dehumidification. In this embodiment, when the ambient temperature is high, only the dehumidification system can be controlled to work to perform dehumidification, thus avoiding the heat pump system shutting down at high temperatures.

[0109] In one embodiment, the garment processing equipment further includes a timing device connected to a control device. The timing device is used to time the working time of the heat pump system, and the control device controls the working state of the moisture absorption and dehumidification system based on the signal fed back by the timing device.

[0110] For example, in one scenario, when the heat pump system is in operation, a timing device tracks the system's operating time. The control device determines whether the system's operating time since startup is less than t1 based on the signal transmitted by the timing device. If it is less than t1, the control device activates the dehumidification system; otherwise, it stops the system. In another scenario, when the heat pump system is in operation, the control device determines whether the remaining operating time is less than t2 based on the signal transmitted by the timing device. If it is less than t2, the control device activates the dehumidification system; otherwise, it stops the system.

[0111] In existing technologies, when using a heat pump dryer to dry clothes, the energy efficiency of the heat pump system is relatively low when it first starts up, resulting in low drying efficiency. In this embodiment, during the time t1 that the heat pump system starts up and operates, the heat pump system and the moisture absorption and dehumidification system are controlled to work simultaneously, which helps to improve the drying efficiency of the dryer.

[0112] In existing technologies, when using a heat pump dryer to dry clothes, the moisture on the clothes decreases in the final stage of drying. As more air enters the drum 15 and carries away the remaining moisture, the evaporator 4 absorbs less heat from the air, which in turn affects the energy efficiency of the heat pump system. In this embodiment, when the heat pump system is still t2 away from ending its operation, the heat pump system and the dehumidification system are controlled to work simultaneously, which helps to improve the drying efficiency of the dryer.

[0113] In this embodiment, the working state of the dehumidification system is controlled according to the working time of the heat pump system, so as to control the operation of the dehumidification system when the energy efficiency of the heat pump system is low, which helps to improve the drying efficiency of the dryer.

[0114] A method for drying clothes using the drying system provided in any of the above embodiments includes the following:

[0115] Determine whether the conditions for simultaneous operation of the heat pump system and the moisture absorption and dehumidification system are met;

[0116] If so, then control the heat pump system and the dehumidification system to work simultaneously;

[0117] If not, the dehumidification system will stop working.

[0118] As mentioned above, the heat pump system includes a compressor 1, a condenser 2, a throttling element 3, and an evaporator 4 connected in sequence; the dehumidification system includes a dehumidification disc 5 and a disc dehumidification device. The dehumidification disc 5 has an adsorption zone and a regeneration zone. The dehumidification disc 5 is located between the evaporator 4 and the condenser 2. The airflow passing through the evaporator 4 can flow to the condenser 2 through the adsorption zone, and the disc dehumidification device can generate hot air to blow onto the regeneration zone. Since the heat pump system has a better drying effect on clothes than the dehumidification system, the heat pump system can be mainly used when drying clothes. However, under certain conditions, such as when the energy efficiency of the heat pump system is relatively low, the heat pump system and the dehumidification system can be controlled to work simultaneously to improve the drying efficiency of the clothes processing equipment.

[0119] In one embodiment, when the heat pump system is in operation: it is determined whether the temperature of the drum in the clothing processing equipment is higher than the preset temperature. If so, the moisture absorption and dehumidification system is controlled to stop working; otherwise, the moisture absorption and dehumidification system is controlled to work.

[0120] Specifically, when the clothing processing equipment dries the clothes in the drum 15, the drum temperature detection sensor detects the temperature in the drum 15 in real time and transmits the detected temperature signal to the control device. When the control device determines that the temperature of the drum 15 is lower than the preset value, for example, the preset value is 65℃, it controls the heat pump system and the moisture absorption and dehumidification system to work simultaneously. When the control device determines that the temperature of the drum 15 is not lower than the preset value, it controls only the heat pump system to work and controls the moisture absorption and dehumidification system to stop working.

[0121] In this embodiment, the working state of the moisture absorption and dehumidification system is determined based on the temperature inside the cylinder 15, which achieves both rapid drying of clothes and energy saving.

[0122] In one embodiment, when the heat pump system is in operation: it is determined whether the running time of the heat pump system from startup is less than t1. If it is less than t1, the dehumidification system is controlled to work. If it is not less than t1, the dehumidification system is controlled to stop working. It is also determined whether the time remaining until the end of operation of the heat pump system is less than t2. If it is less than t2, the dehumidification system is controlled to work. If it is not less than t2, the dehumidification system is controlled to stop working.

[0123] In existing technologies, when using a heat pump dryer to dry clothes, the energy efficiency of the heat pump system is relatively low when it first starts up, resulting in low drying efficiency. In this embodiment, during the time t1 that the heat pump system starts up and operates, the heat pump system and the moisture absorption and dehumidification system are controlled to work simultaneously, which helps to improve the drying efficiency of the dryer.

[0124] In existing technologies, when using a heat pump dryer to dry clothes, the moisture on the clothes decreases in the final stage of drying. As more air enters the drum 15 and carries away the remaining moisture, the evaporator 4 absorbs less heat from the air, which in turn affects the energy efficiency of the heat pump system. In this embodiment, when the heat pump system is still t2 away from ending its operation, the heat pump system and the dehumidification system are controlled to work simultaneously, which helps to improve the drying efficiency of the dryer.

[0125] In this embodiment, the working state of the dehumidification system is controlled according to the working time of the heat pump system, so as to control the operation of the dehumidification system when the energy efficiency of the heat pump system is low, which helps to improve the drying efficiency of the dryer.

[0126] In one embodiment, when the heat pump system is in operation: it is determined whether the ambient temperature is lower than a first preset temperature value; if so, the dehumidification system is controlled to operate; if not, the dehumidification system is controlled to stop operating.

[0127] Specifically, when the clothing processing equipment dries the clothes in the drum 15, the ambient temperature detection sensor detects the temperature of the environment in which the clothing processing equipment is located in real time and transmits the detected temperature signal to the control device. When the control device determines that the ambient temperature is lower than the first preset ambient temperature value, it controls the heat pump system and the moisture absorption and dehumidification system to work simultaneously; when the control device determines that the ambient temperature is not lower than the first preset ambient temperature value, it controls only the heat pump system to work.

[0128] In this embodiment, when a low ambient temperature is detected, the heat pump system and the moisture absorption and dehumidification system can be controlled to work simultaneously to improve the drying speed of the clothes processing equipment.

[0129] In one embodiment, when the heat pump system is in operation: if the ambient temperature is higher than a second preset temperature value, then the heat pump system is controlled to stop working and the dehumidification system is controlled to work; if not, the heat pump system is controlled to continue working.

[0130] When the ambient temperature is high, the heat pump system compressor 1 will be under heavy load and may shut down. Therefore, if the ambient temperature is higher than the second preset temperature value, the heat pump system can be controlled to stop working, and the dehumidification system can be controlled to work to dehumidify.

[0131] In this embodiment, when the ambient temperature is relatively high, only the moisture absorption and dehumidification system can be controlled to work, and dehumidification can be performed by the moisture absorption and dehumidification system to avoid the heat pump system from shutting down at high temperatures.

[0132] In one embodiment, it is determined whether the conditions for the dehumidification system to operate independently are met; if they are met, the dehumidification system is controlled to operate independently.

[0133] The method for drying clothes provided in this embodiment also includes using a separate moisture absorption and dehumidification system to dehumidify the clothes. That is, when the conditions for the dehumidification system to work alone are met, such as when the clothes processing equipment receives an instruction to only operate the moisture absorption and dehumidification system, it can control the moisture absorption and dehumidification system to work alone.

[0134] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
