Specifically, the use of the words "in one embodiment," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner.
[0034] Heat pump dryers are lacking in drying speed, especially when the ambient temperature is low or high.
[0035] Please refer to Figure 1, which shows 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. This liquid refrigerant then passes through throttling element 3, where it is cooled and depressurized into low-temperature, low-pressure two-phase gas-liquid refrigerant. It then enters evaporator 4, absorbs heat, and vaporizes into medium-temperature, low-pressure gaseous refrigerant. Finally, it is compressed by compressor 1 into high-temperature, high-pressure gaseous refrigerant. The airflow 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 10 into drum 11, carrying away moisture from the clothes. After being cooled and condensed in evaporator 4, the air flows back to condenser 2 for reheating, and the cycle repeats continuously. The liquid water condensed on the surface of evaporator 4 falls into a water collector below evaporator 4.
[0036] 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 within the evaporator. A 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 11. Therefore, in low-temperature environments, the dryer's drying speed is slow. Conversely, when the ambient temperature is high, the heat pump system compressor 1 experiences a heavy workload and may shut down, further slowing down the drying process.
[0037] To address the above issues, this embodiment provides a drying system for a garment processing device. The garment processing device can be a dryer or a washer-dryer combo. The garment processing device includes a heat pump system and a moisture absorption and dehumidification system.
[0038] Please refer to 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, medium-temperature liquid refrigerant. It is then cooled and depressurized by the throttling element 3 to become a low-temperature, 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.
[0039] The dehumidification system includes a dehumidification disc 5 and a disc dehumidification device. Please refer to Figure 2, which shows the dehumidification disc 5. The dehumidification disc 5 is located on the air inlet side of the evaporator 4, that is, the airflow passing through the dehumidification disc 5 can flow from the evaporator 4 to the condenser 2. The dehumidification disc 5 is used to dehumidify the air passing through it.
[0040] Regarding the dehumidifying disc 5, specifically, it 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; that is, hot air generated by the disc dehumidifier is blown towards 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 disc dehumidifier, thus heating the air passing through it.
[0041] Regarding the dehumidification turntable 5, it can be a honeycomb or corrugated turntable carrying a desiccant, capable of adsorbing and desorbing absorbed water vapor to achieve repeated desorption and regeneration. In other embodiments, the dehumidification turntable 5 includes an inorganic / organic fiber carrier (such as ceramics, glass fibers, MOFs, COFs, cordierite, etc.), coated with a desiccant such as a molecular sieve. The desiccant is evenly distributed between and on the surface of the fiber carrier to achieve adsorption of moisture in the airflow. In some embodiments, the desiccant can be zeolite, modified / synthetic zeolite, molecular sieves (including but not limited to single-crystal or mixed-crystal molecular sieves such as A-type molecular sieves, X / Y-type molecular sieves, ZSM molecular sieves, Beta molecular sieves, etc.), polymeric desiccant, alkali metal aluminosilicates (13X molecular sieves), lithium chloride, silica gel, modified silica gel, activated alumina, and other materials with hygroscopic properties.
[0042] When the drying system provided in this embodiment is applied to a clothing processing device and the heat pump system and the dehumidification system work simultaneously, please refer to Figure 2. The flow direction of the circulating air in the clothing processing device is as follows: After passing through the condenser 2, the circulating air is heated into high-temperature dry air. Then, it enters the cylinder 11 through the impeller 10 to remove moisture from the clothes. After passing through the filter screen 12, the air flows to the adsorption area of the dehumidification disc 5. After being dehumidified by the adsorption area of the dehumidification disc 5, it flows to the evaporator 4. After being cooled and condensed into water by the evaporator 4, it flows back to the condenser 2 to be heated, and the cycle repeats.
[0043] When the ambient temperature is low, the heat pump system and the dehumidification system of the drying system can be controlled to work simultaneously to improve the drying speed of the clothing processing equipment. When the ambient temperature is high, the dehumidification turntable 5 can effectively share the load of the heat pump system, which helps to prevent the heat pump system from shutting down under high temperature conditions. In addition, when the ambient temperature is high, only the dehumidification system can be controlled to work, and the dehumidification system can be used to perform dehumidification, avoiding the heat pump system from shutting down under high temperature conditions, which would affect the drying speed of the clothing processing equipment.
[0044] In addition, the relatively low energy efficiency of the heat pump system when it is first started results in low drying efficiency of the dryer. In this embodiment, by setting the dehumidification turntable 5 on the air inlet side of the evaporator 4, the humid air discharged from the cylinder 11 is first dehumidified by the dehumidification turntable 5, which can effectively share the load of the heat pump system and improve the drying speed of the clothing processing equipment.
[0045] Regarding the filter screen 12 located upstream of the airflow in the evaporator 4, as the airflow enters the cylinder 11, it carries away the moisture from the clothes and also carries away the lint from the clothes. The filter screen 12 has the function of filtering lint in the air to prevent a large amount of lint from adsorbing on the surface of the evaporator 4 and affecting the heat exchange between the evaporator 4 and the air.
[0046] The drying system provided in this embodiment dehumidifies the humid air discharged from the drum 11 by passing it through the dehumidification turntable 5, which can effectively share the load of the heat pump system. At the same time, the heat pump system and the moisture absorption and dehumidification system work simultaneously, which can improve the drying speed of the clothing processing equipment.
[0047] Please refer to Figures 3 and 4. In one embodiment, the rotary dehumidifier includes a heater 6, a first fan 7, and a cooler 8. Driven by the first fan 7, the air heated by the heater 6 flows to the regeneration zone, and the airflow passing through the regeneration zone is dehumidified by the cooler 8 before flowing back to the heater 6.
[0048] 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 Figures 3 and 4, which show that the first fan 7 can be located between the heater 6 and the cooler 8. In this case, when the first fan 7 is working, the flow direction of the circulating air is as follows: the medium-temperature and 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, and then enters the regeneration zone of the dehumidification disc 5, which carries away the moisture in the regeneration zone. The air then flows to the cooler 8 and condenses into liquid water, becoming medium-temperature and low-humidity gas that continues to circulate. The liquid water condensed on the surface of the cooler 8 falls into the water collector 18.
[0049] In some embodiments, heater 6 is an electric heating tube, an electric heating wire, or a thermistor heater.
[0050] 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.
[0051] In an example of a rotary dehumidifier including a heater 6, a first fan 7, and a cooler 8, in one embodiment (see Figure 3), the cooler 8 is a water-cooled heat exchanger with a water flow pipe inside. In another embodiment (see Figure 4), the rotary dehumidifier also includes a second fan 9. A first heat exchange duct 801 and a second heat exchange duct 802 are formed inside the cooler 8. Driven by the first fan 7, air passing through the regeneration zone flows through the first heat exchange duct 801 to the first fan 7. The second fan 9 drives air outside the garment processing equipment to flow to the second heat exchange duct 802 for dehumidifying the air passing through the regeneration zone.
[0052] In the example of the rotary dehumidifier with the second fan 9, please refer to Figure 5. A first heat exchange duct 801 and a second heat exchange duct 802 are formed inside the cooler 8. The first heat exchange duct 801 and the second heat exchange duct 802 are not connected. The air passing through the regeneration zone flows to the first fan 7 through the first heat exchange duct 801. The second fan 9 drives the air outside the clothing processing equipment to flow to the second heat exchange duct 802. The air flowing in the second heat exchange duct 802 exchanges heat with the air flowing in the first heat exchange duct 801. That is, the air flowing in the second heat exchange duct 802 absorbs the heat of the air flowing in the first heat exchange duct 801, so as to achieve condensation and dehumidification of the air passing through the regeneration zone of the dehumidification rotary disc 5.
[0053] Regarding the specific structure of the cooler 8, in one example, please refer to Figure 5. The first heat exchange duct 801 is connected along the X direction in Figure 5, and multiple first heat exchange ducts 801 are spaced apart along the Y-axis in Figure 5. The second heat exchange duct 802 is connected along the Z direction in Figure 5, and multiple second heat exchange ducts 802 are spaced apart along the Y-axis in Figure 5. The first heat exchange ducts 801 and the second heat exchange ducts 802 are not connected. The cooler 8 is made of heat transfer material. Driven by the first fan 7, the air passing through the regeneration zone is diverted through each of the first heat exchange ducts 801. Under the action of the second fan 9, the air outside the clothing processing equipment is diverted through each of the second heat exchange ducts 802.
[0054] In this embodiment, when the second fan 9 is working, it drives the air outside the clothing processing equipment to flow into the second heat exchange duct 802. After passing through the second heat exchange duct 802, the air is discharged outside the clothing processing equipment through the space inside the equipment. In one example, the rotary dehumidifier includes an air inlet duct and an air outlet duct. The air inlet duct is connected to the air inlet side of the second heat exchange duct 802 of the cooler 8, and the air outlet duct is connected to the air outlet side of the second heat exchange duct 802 of the cooler 8. The second fan 9 is located on the air inlet duct or the air outlet duct. Driven by the second fan 9, the air outside the clothing processing equipment is driven to flow through the air inlet duct to the second heat exchange duct 802 of the cooler 8, and then discharged outside the clothing processing equipment through the air outlet duct.
[0055] In some embodiments, an air intake duct and an exhaust duct are formed within the garment processing equipment. The air intake duct inlet is formed on the housing of the garment processing equipment, and the exhaust duct outlet is formed on the housing of the garment processing equipment. Typically, the housing of the garment processing equipment includes a front side panel, a rear side panel, a left side panel, a right side panel, a top panel, and a bottom panel. The top panel and the bottom panel are vertically opposed to each other along the height direction of the garment processing equipment, the front side panel and the rear side panel are vertically opposed to each other along the front-rear direction of the garment processing equipment, and the left side panel and the right side panel are vertically opposed to each other along the left-right direction of the garment processing equipment. In some embodiments, the air intake duct inlet is formed on the bottom panel, and the exhaust duct outlet is formed on the rear side panel.
[0056] In one embodiment, a first damper and a second damper are provided on the housing of the main body of the device. The first damper is used to open or close the air inlet of the air intake duct, and the second damper is used to open or close the air outlet of the exhaust duct. Both the first damper and the second damper are connected to the control device of the clothing processing equipment. When the moisture absorption and dehumidification system is in operation, the first damper and the second damper are controlled to open; when the moisture absorption and dehumidification system is not in operation, the first damper and the second damper are controlled to close.
[0057] In this embodiment, by utilizing the airflow outside the clothing processing equipment to the second heat exchange duct 802 of the cooler 8 to exchange heat and dehumidify with the air passing through the regeneration zone, the cost of dehumidifying the regeneration zone can be reduced by using the air outside the clothing processing equipment as the heat exchange medium.
[0058] In an example where the rotary dehumidifier includes a heater 6, a first fan 7, and a cooler 8, and the cooler 8 is a water-cooled heat exchanger, in some embodiments, a water flow pipe is provided inside the cooler 8.
[0059] 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.
[0060] 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.
[0061] Regarding the water source for the cooler 8, in one embodiment, the rotary dehumidifier includes a water inlet pipe 15, one end of which is connected to the water inlet of the cooler 8; the other end of the water inlet pipe 15 is connected to a water inlet solenoid valve on the garment processing equipment (the water inlet solenoid valve is connected to an external faucet). That is, in this embodiment, the water inlet for the cooler 8 originates from outside the garment processing equipment.
[0062] In this embodiment, an inlet valve body 16 is provided on the water inlet pipe 15. The inlet valve body 16 is connected to the control device of the drying system, and the control device can control the opening and closing of the inlet valve body 16. In some embodiments, for a clothing processing device equipped with the drying system provided in this embodiment, when the dehumidification system needs to work, the control device controls the inlet valve body 16 to open, so that the tap water flowing out of the inlet solenoid valve can flow through the inlet pipe 15 to the cooler 8; when the dehumidification system does not need to work, the control device controls the inlet valve body 16 to close. In this embodiment, by using tap water as the water source for the cooler 8, the low temperature of the tap water allows the cooler 8 to effectively dehumidify the air passing through it.
[0063] Regarding the water source for the cooler 8, in another embodiment, the rotary dehumidifier includes a water inlet pipe 15, 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 18 located below the evaporator 4, and a water pump 17 is provided on the water inlet pipe 15.
[0064] When the water pump 17 is started, the water in the water collector 18 can flow to the cooler 8 through the water inlet pipe 15. That is, in this embodiment, the water in the cooler 8 comes from the inside of the clothing processing equipment. The condensate in the water collector 18 flows into the cooler 8 and exchanges heat with the air passing over the surface of the cooler 8.
[0065] During the operation of the garment processing equipment, condensate dripping from the evaporator 4 and cooler 8 continuously falls into the water collector 18. In one example, a low water level detection sensor and a high water level detection sensor can be installed in the water collector 18. Along the height direction of the water collector 18, 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 17 are all connected to the control device of the drying system. The start of the water pump 17 depends on the water level in the water collector 18. In some embodiments, when the high water level detection sensor detects a water level, it indicates that there is a lot of water in the water collector 18, and the control device can control the water pump 17 to start. At the same time, it also controls the heater 6 and the first fan 7 to work, so that the dehumidification system dehumidifies the air in the cylinder 11. 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 18. At this time, the control device controls the water pump 17, the heater 6, and the first fan 7 not to start.
[0066] During the operation of the clothing processing equipment, condensate water falling from the evaporator 4 and cooler 8 continuously falls into the water collector 18. In another example, the rotation speed of the water pump 17 can be controlled so that, in scenarios requiring dehumidification using a moisture absorption and dehumidification system, the water pump 17 can remain operational to dehumidify the air in the drum 11 through the moisture absorption and dehumidification system. In some embodiments, 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 18. Along the height direction of the water collector 18, 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 18. The rotation speed of the water pump 17 can be increased so that the amount of water pumped out of the water collector 18 per unit time is greater than the amount of water falling from the evaporator 4 and cooler 8 into the water collector per unit time. The water volume in collector 18; when the high water level detection sensor does not detect the water level but the low water level detection sensor detects the water level, the speed of water pump 17 can be reduced so that the amount of water pump 17 draws from collector 18 per unit time is equal to the amount of water falling from evaporator 4 and cooler 8 into collector 18 per unit time; when the low water level detection sensor does not detect the water level, it indicates that the water volume in collector 18 is low, and the speed of water pump 17 can be further reduced so that the amount of water pump 17 draws from collector 18 per unit time is less than the amount of water falling from evaporator 4 and cooler 8 into collector 18 per unit time.
[0067] In this embodiment, the condensate from the water collector 18 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 indoor placement of the clothing processing equipment.
[0068] Regarding the water source for the cooler 8, in one embodiment, please refer to Figure 6. The rotary dehumidifier includes a water inlet pipe 15, which comprises a first water inlet pipe section 1501, a second water inlet pipe section 1502, and a third water inlet pipe section 1503. One end of each of these sections is connected via a water inlet valve body 16. The other end of the first water inlet pipe section 1501 is connected to the water inlet of the cooler 8. The other end of the second water inlet pipe section 1502 is connected to a water collector 18. A water pump 17 is installed on the second water inlet pipe section 1502. The other end of the third water inlet pipe section 1503 is connected to a water inlet solenoid valve on 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 18.
[0069] In scenarios where a dehumidification system is required, the condensate in the water collector 18 can be used first. When the condensate in the water collector 18 is insufficient, external water from the clothing processing device is then controlled to enter the cooler 8. In some embodiments, for clothing processing devices 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 18. Along the height direction of the water collector 18, 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 18. The control device controls the inlet valve body 16 to connect the first inlet pipe section 1501 and the second inlet pipe section 1502. The first inlet pipe section 1501 and the third inlet pipe section 1503 form a barrier. In the off state, the water pump 17 is started, and the heater 6 and the first fan 7 are also started to work, so that the dehumidification system dehumidifies the air in the cylinder 11. When the low water level detection sensor does not detect the water level, it means that the water in the water collector 18 is low. At this time, the control device controls the water pump 17 not to start, and the control device controls the water inlet valve body 16 to block the first water inlet pipe section 1501 and the second water inlet pipe section 1502. The first water inlet pipe section 1501 and the third water inlet pipe section 1503 are connected, so that the water flowing out of the water inlet solenoid valve can flow to the cooler 8 through the first water inlet pipe section 1501 and the third water inlet pipe section 1503.
[0070] In this embodiment, not only can the condensate collected by the water collector 18 be utilized, but the normal operation of the dehumidification system can also be ensured.

[0072] When branch pipe section 1902 is used to draw water to the outside of the garment processing equipment, one end of branch pipe section 1902 can be connected to a floor drain on the base plate. When the sewage pump 20 starts, the water in the cooler 8 is discharged through the outlet pipe 19 to the sewer, so that the water flowing out of the cooler 8 can be discharged from the garment processing equipment in a timely manner. When a water box 21 is installed on the garment processing equipment, branch pipe section 1902 can also be connected to the water box 21 to draw water to the water box 21 through the outlet pipe 19.

The water box connecting pipe 23 is connected to the water box 21, and the drain pipe 24 is used to discharge the water in the water collector 18 out of the clothing processing equipment. When the water pump 17 is started, the water inlet valve body 16 can be controlled to pump the water in the water collector 18 to the cooler 8, or to the water box 21, or to the drain pipe 24.
[0077] The water inlet pipe 15 includes a first water inlet pipe section 1501, a second water inlet pipe section 1502, and a third water inlet pipe section 1503.

In an example where the other end of the third water inlet pipe section 1503 is connected to a water valve outside the clothing processing equipment, please refer to Figure 9. A control valve 25 can be installed on the second water inlet pipe section 1502. The control valve 25 is located between the water inlet valve body 16 and the water pump 17. A water box connecting pipe 23 and a drain pipe 24 are connected to the control valve 25. The water box connecting pipe 23 is connected to the water box 21. The drain pipe 24 is used to discharge the water in the water collector 18 to the outside of the clothing processing equipment.
[0078] Please refer to Figure 10. In one embodiment, the rotary dehumidifier includes a heater 6, a first fan 7, and a flow duct. The heater 6 and the first fan 7 are located on the flow duct. Driven by the first fan 7, air outside the clothing processing equipment can flow to the regeneration zone through the flow duct. Air passing through the regeneration zone can be discharged outside the clothing processing equipment through the flow duct. The heater 6 can heat the air flowing to the regeneration zone.
[0079] In this embodiment, when the first fan 7 is working, it drives the air outside the clothing processing equipment to flow to the regeneration zone through the airflow duct. The air passing through the regeneration zone can be discharged to the outside of the clothing processing equipment through the airflow duct. That is, in this embodiment, the air outside the clothing processing equipment is used and heated to flow to the regeneration zone of the dehumidification turntable 5. The air passing through the regeneration zone of the dehumidification turntable 5 carries away the moisture in the regeneration zone and then flows to drive the clothing processing equipment to the outside.
[0080] Regarding the airflow duct, in one embodiment, please refer to FIG10. The airflow duct includes a first air intake duct 13 and a first exhaust duct 14. The heater 6 is located in the first air intake duct 13, and the first fan 7 is located in the first air intake duct 13 or in the first exhaust duct 14.
[0081] In this embodiment, the first fan 7 can be located in the first air intake duct 13 or in the first exhaust duct 14. Alternatively, two first fans 7 can be provided, located in the first air intake duct 13 and the first exhaust duct 14 respectively.
[0082] Please refer to Figure 10, which shows that both the heater 6 and the first fan 7 are located on the first air intake duct 13, and the first fan 7 is located upstream of the airflow direction of the heater 6. Driven by the first fan 7, the air outside the garment processing equipment is driven through the first air intake duct 13 and the heater 6 in the first air intake duct 13 to the regeneration zone. The air passing through the regeneration zone is discharged outside the garment processing equipment through the first exhaust duct 14.
[0083] In some embodiments, a first air intake duct 13 and a first exhaust duct 14 are formed within the garment processing apparatus. The air inlet of the first air intake duct 13 is formed on the housing of the garment processing apparatus, and the air outlet of the first exhaust duct 14 is formed on the housing of the garment processing apparatus. In some embodiments, the air inlet of the first air intake duct 13 is formed on the bottom plate, and the air outlet of the first exhaust duct 14 is formed on the rear side plate.
[0084] In this embodiment, the position of the first fan 7 can be reasonably set according to the internal layout of the clothing processing equipment.
[0085] In one embodiment, an air inlet damper 26 and an air outlet damper 27 are provided on the housing of the main body of the device. The air inlet damper 26 is used to open or close the air inlet of the first air inlet duct 13, and the air outlet damper 27 is used to open or close the air outlet of the first exhaust duct 14.
[0086] Please refer to Figure 10, which illustrates the air inlet damper 26 and the air outlet damper 27. Both the air inlet damper 26 and the air outlet damper 27 are connected to the control device of the garment processing equipment. When the dehumidification system is in operation, the air inlet damper 26 and the air outlet damper 27 are opened, that is, the air inlet damper 26 is opened to the air inlet of the first air intake duct 13, and the air outlet damper 27 is opened to the air outlet of the first exhaust duct 14. When the dehumidification system is not in operation, the air inlet damper 26 and the air outlet damper 27 are closed, that is, the air inlet damper 26 is closed to the air inlet of the first air intake duct 13, and the air outlet damper 27 is closed to the air outlet of the first exhaust duct 14.
[0087] In some embodiments, a filter device is provided at the air inlet of the first air intake duct 13 to filter the air flowing into the first air intake duct 13.
[0088] In this embodiment, by setting an air inlet damper 26 and an air outlet damper 27, it is possible to prevent debris from entering the clothing processing equipment through the air inlet of the first air inlet duct 13 and the air outlet of the first exhaust duct 14 when the moisture absorption and dehumidification system is not working.
[0089] 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 located on the air inlet side of the evaporator 4. The airflow passing through the dehumidification turntable 5 can flow from the evaporator 4 to the condenser 2. The turntable dehumidification device can generate hot air and blow it towards the regeneration zone.
[0090] The clothing processing equipment provided in this embodiment first dehumidifies the humid air discharged from the drum 11 through the dehumidification turntable 5, which can effectively share the load of the heat pump system. At the same time, the heat pump system and the moisture absorption and dehumidification system work simultaneously, which can improve the drying speed of the clothing processing equipment.
[0091] 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.
[0092] 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 rotary table 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 rotary table dehumidification mode means both the heat pump system and the moisture absorption and dehumidification system are operating simultaneously.
[0093] In some embodiments, when a single moisture absorption and dehumidification system is used 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 to achieve the dehumidification effect. In addition, as mentioned above, when the regeneration zone of the dehumidification disc 5 is regenerated and the dehumidification disc 5 rotates to form an adsorption zone, the adsorption zone has the heat provided by the disc dehumidification device, so the adsorption zone can heat the air passing through it. Therefore, when a single moisture absorption and dehumidification system is used in dehumidification mode, it can also dry the clothes inside the drum.
[0094] When the clothing processing equipment dries a single batch of wet clothes, it can operate in one working mode during the drying process. In some embodiments, it may operate only in a single heat pump system dehumidification mode or only in a heat pump and turntable dehumidification mode that works simultaneously. Alternatively, during the drying process, it may operate in a single heat pump system dehumidification mode, a heat pump and turntable dehumidification mode, or a single moisture absorption and dehumidification system dehumidification mode at different time periods.
[0095] In some embodiments, when the ambient temperature is relatively 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 turntable work simultaneously; when the ambient temperature is relatively 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 dehumidification mode with a single moisture absorption and dehumidification system.
[0096] 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 turntable 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.
[0097] 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.
[0098] 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 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.
[0099] In some embodiments, when the clothing processing equipment dries the clothes in the drum, the drum temperature detection sensor detects the temperature in the drum in real time and transmits the detected temperature signal to the control device. When the control device determines that the temperature of the drum is lower than a third preset temperature value, in some embodiments, the third preset temperature value is 65°C, then the heat pump system and the moisture absorption and dehumidification system are controlled to work simultaneously; when the control device determines that the temperature of the drum is not lower than the third preset temperature value, then only the heat pump system is controlled to work.
[0100] In this embodiment, by setting the working state of the moisture absorption and dehumidification system to be determined based on the temperature inside the drum, it can achieve the effect of quickly drying clothes while saving energy.
[0101] 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.
[0102] In some embodiments, when the clothing processing equipment dries the clothes in the drum, 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 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 temperature value, it controls only the heat pump system to work.
[0103] 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.
[0104] In some embodiments, when the clothing processing equipment dries the clothes in the drum 11, 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 temperature value, it controls the dehumidification system to work.
[0105] When the ambient temperature is high, the heat pump system compressor 1 will be under heavy load and may shut down. Therefore, when the ambient temperature exceeds a second preset temperature value, the heat pump system can be controlled to stop working, and the dehumidification system can be controlled to operate for dehumidification. In this embodiment, when the ambient temperature is high, only the dehumidification system can be controlled to operate, thus avoiding the heat pump system shutting down at high temperatures.
[0106] 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.
[0107] In one example, when the heat pump system is in operation, a timing device tracks the operating time. The control device determines whether the operating time of the heat pump system since startup is less than t1 based on the signal transmitted by the timing device. If it is less than t1 (t1 can be 2-5 minutes), the control device activates the dehumidification system; otherwise, it stops operating. In another example, 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 (t2 can be 2-5 minutes), the control device activates the dehumidification system; otherwise, it stops operating.
[0108] In related 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.
[0109] In related technologies, when using a heat pump dryer to dry clothes, during the final stage of drying, the moisture on the clothes decreases, and the amount of moisture carried away by the air entering the drum decreases, resulting in less heat absorption by the evaporator 4, 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 operation, 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.
[0110] 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.
[0111] The beneficial effects of this disclosure are as follows: In the drying system provided in this embodiment, the humid air discharged from the drum is first dehumidified by the dehumidification turntable, which can effectively share the load of the heat pump system. At the same time, the heat pump system and the moisture absorption and dehumidification system work simultaneously, which can improve the drying speed of the clothing processing equipment.
[0112] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
