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 low or high. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings. The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0038] In the description of this application, it should be understood that the terms "length", "width", "thickness", "top", "bottom", "inner", "outer", "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application.

[0039] To facilitate a clear description of the technical solutions of this application, the terms "first" and "second" are used to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that the terms "first" and "second" do not necessarily imply that they are different.

[0040] In this application, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0042] It should be noted that, in this application, the words "in one embodiment," "exemplarily," and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "in one embodiment," "exemplarily," or "for example" should not be construed as being more preferred or advantageous than other embodiments or designs. 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.

[0043] 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, where it is cooled and depressurized into low-temperature, low-pressure gas-liquid two-phase refrigerant. This refrigerant enters evaporator 4, absorbs heat, and vaporizes into medium-temperature, low-pressure gaseous refrigerant. Compressor 1 then compresses it 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.

[0044] 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. 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 air through the drum 11. Therefore, the drying speed of the dryer is slow in low-temperature environments. Conversely, when the ambient temperature is high, the compressor 1 of the heat pump system operates under heavy load and may shut down, causing a slow drying speed.

[0045] 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.

[0046] 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.

[0047] The moisture absorption and dehumidification system includes a dehumidification disc 5 and a disc dehumidification device. Please refer to [link / reference]. Figure 2 The diagram illustrates the dehumidification turntable 5, which is located on the air inlet side of the evaporator 4. This means that the airflow passing through the dehumidification turntable 5 can flow from the evaporator 4 to the condenser 2. The dehumidification turntable 5 is used to dehumidify the air passing through it.

[0048] 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.

[0049] 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. The desiccant can be, for example, 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.

[0050] 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 of the circulating air in the clothing processing equipment is as follows: after passing through the condenser 2, the circulating air is heated into high-temperature dry air, and then enters the cylinder 11 through the impeller 10 to remove the 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.

[0051] 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.

[0052] 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.

[0053] Regarding the filter screen 12 installed at the front end of the airflow of the evaporator 4, the airflow entering the cylinder 11 carries away the moisture on the clothes and also carries away the lint on the clothes. The filter screen 12 has the function of filtering the 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.

[0054] 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.

[0055] Please see Figure 3 and Figure 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 in the regeneration zone is dehumidified by the cooler 8 and then flows to the heater 6.

[0056] 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 3 and Figure 4 This illustrates that the first fan 7 can be positioned 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 18.

[0057] Preferably, heater 6 is an electric heating tube, an electric heating wire, or a thermistor heater.

[0058] 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.

[0059] In an example of a rotary dehumidifier including a heater 6, a first fan 7, and a cooler 8, please refer to [link to example]. Figure 3 Cooler 8 is a water-cooled heat exchanger, and water pipes are installed inside cooler 8; in another embodiment, please refer to Figure 4 The rotary dehumidifier also includes a second fan 9. The cooler 8 has a first heat exchange duct 801 and a second heat exchange duct 802. Driven by the first fan 7, the air passing through the regeneration zone flows to the first fan 7 through the first heat exchange duct 801. The second fan 9 is used to drive the air outside the clothing processing equipment to flow to the second heat exchange duct 802 for dehumidifying the air passing through the regeneration zone.

[0060] For an example of a rotary dehumidifier with a second fan 9, please refer to [link / reference]. Figure 5The cooler 8 has a first heat exchange duct 801 and a second heat exchange duct 802. The first heat exchange duct 801 and the second heat exchange duct 802 are not connected. The air passing through the regeneration zone flows through the first heat exchange duct 801 to the first fan 7. 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 realize the condensation and dehumidification of the air passing through the regeneration zone of the dehumidification turntable 5.

[0061] For a specific example of the structure of cooler 8, please refer to [link / reference]. Figure 5 The connecting direction of the first heat exchange duct 801 is along Figure 5 The direction of X, along Figure 5 Multiple first heat exchange ducts 801 are spaced apart along the Y-axis; the connecting direction of the second heat exchange duct 802 is along... Figure 5 In the direction of Z, along Figure 5 Multiple second heat exchange ducts 802 are spaced apart along the Y-axis, and the first heat exchange duct 801 is not connected to the second heat exchange duct 802. 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, and 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.

[0062] In this embodiment, when the second fan 9 is working, the second fan 9 can drive the air outside the clothing processing equipment to flow to 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 clothing processing equipment. For example, in a specific 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.

[0063] Specifically, the air intake duct and 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 panel, a rear panel, a left panel, a right panel, a top panel, and a bottom panel. The top and bottom panels are arranged vertically opposite each other along the height of the garment processing equipment, the front and rear panels are arranged vertically opposite each other along the front-rear direction of the garment processing equipment, and the left and right panels are arranged horizontally opposite each other along the left-right direction of the garment processing equipment. Preferably, the air intake duct inlet is formed on the bottom panel, and the exhaust duct outlet is formed on the rear panel.

[0064] 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 garment processing equipment. When the rotary dehumidification system is in operation, the first damper and the second damper are controlled to open; when the rotary dehumidification system is not in operation, the first damper and the second damper are controlled to close.

[0065] 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.

[0066] 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, specifically, a water flow pipe is provided inside the cooler 8.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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. Specifically, for the clothing processing equipment 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.

[0071] 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.

[0072] 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.

[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 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 the height 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. 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 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 drum 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.

[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 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. 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 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 by the water pump 17 per unit time is greater than the amount of water falling from the evaporator 4 and cooler 8 into the water collector 18 per unit time. The water level in the collector 18 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 17 can be reduced so that the amount of water pumped out of the collector 18 by the water pump 17 per unit time is equal to the amount of water falling from the evaporator 4 and the cooler 8 into the collector 18 per unit time. When the low water level sensor does not detect the water level, it indicates that the water level in the collector 18 is low. The speed of the water pump 17 can be further reduced so that the amount of water pumped out of the collector 18 by the water pump 17 per unit time is less than the amount of water falling from the evaporator 4 and the cooler 8 into the collector 18 per unit time.

[0075] 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.

[0076] Regarding the water inlet source of 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, and the other end of the second water inlet pipe section 1502 is connected to a water collector 18. A water pump 17 is mounted 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 inlet 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.

[0077] In scenarios where dehumidification using a moisture absorption and 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 garment processing equipment is controlled to enter the cooler 8. Specifically, for garment 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 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 18. The control device controls the water inlet valve body 16 to connect the first water inlet pipe section 1501 and the second water inlet pipe section 1502, while the first water inlet pipe section 1501 and the third water inlet section 1503 are blocked. The system then controls the water pump 17 to start, and simultaneously controls the heater 6 and the first fan 7 to operate, 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 indicates that the water volume in the water collector 18 is low. At this time, the control device controls the water pump 17 not to start, and controls the inlet valve body 16 to block 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 are connected, so that the water flowing out of the inlet solenoid valve can flow to the cooler 8 through the first inlet pipe section 1501 and the third inlet pipe section 1503.

[0078] In this embodiment, it is possible not only to utilize the condensate collected by the water collector 18, 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 19, which includes a main pipe section 1901 and a branch pipe section 1902. A sewage pump 20 is installed on the main pipe section 1901. One end of the main pipe section 1901 is connected to the water outlet of the cooler 8. The other end of the main pipe section 1901 is connected to a branch pipe section 1902, which is used to draw water to the outside of the clothing processing equipment or to draw water to the water box 21 on the clothing processing equipment.

[0080] 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. When the water box 21 is full, the user can pull out the water box 21, empty the water in the water box 21, and then insert it back into the garment processing equipment.

[0081] Regarding the drainage of the cooler 8, in another embodiment, the rotary dehumidifier includes a water outlet pipe 19, which comprises a main pipe section 1901 and branch pipe sections 1902. A sewage pump 20 is installed on the main pipe section 1901. One end of the main pipe section 1901 is connected to the water outlet of the cooler 8, and the other end of the main pipe section 1901 is provided with a water outlet valve body 22. Two branch pipe sections 1902 are connected to the water outlet valve body 22, which are used to draw water to the outside of the clothing processing equipment and to draw water to the water box 21 on the clothing processing equipment, respectively. By controlling the water outlet valve body 22, water can be drawn to the outside of the clothing processing equipment or to the water box 21 on the clothing processing equipment when the sewage pump 20 is started. 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.

[0082] Regarding the drainage of the cooler 8, in another embodiment, the rotary dehumidifier includes a water outlet pipe 19, which includes a main pipe section 1901 and branch pipe sections 1902. A sewage pump 20 is installed on the main pipe section 1901. One end of the main pipe section 1901 is connected to the water outlet of the cooler 8, and the other end of the main pipe section 1901 is provided with a water outlet valve body 22. Two or more branch pipe sections 1902 are connected to the water outlet valve body 22. One branch pipe section 1902 is used to draw water to the water collector 18 below the evaporator 4, and the other branch pipe sections 1902 are used to draw water to the outside of the clothing processing equipment or to draw water to the water box 21 on the clothing processing equipment.

[0083] For example, two branch pipe sections 1902 are connected to the outlet valve body 22. One branch pipe section 1902 is used to draw water to the water collector 18 below the evaporator 4, and the other branch pipe section 1902 is used to draw water to the outside of the laundry handling equipment. Alternatively, two branch pipe sections 1902 are connected to the outlet valve body 22. One branch pipe section 1902 is used to draw water to the water collector 18 below the evaporator 4, and the other branch pipe section 1902 is used to draw water to the water box 21 on the laundry handling equipment. Or, please see Figure 7 Three branch pipe sections 1902 are connected to the water outlet valve body 22. One branch pipe section 1902 is used to draw water to the water collector 18 below the evaporator 4. Of the other two branch pipe sections 1902, one branch pipe section 1902 is used to draw water to the outside of the clothing processing equipment, and the other branch pipe section 1902 is used to draw water to the water box 21 on the clothing processing equipment.

[0084] When one end of the water inlet pipe 15 is connected to the water inlet of the cooler 8, and the other end of the water inlet pipe 15 is connected to the water collector 18 located below the evaporator 4, and a water pump 17 is installed on the water inlet pipe 15, please refer to Figure 8In one embodiment, the inlet valve body 16 can be disposed between the water pump 17 and the cooler 8. The inlet valve body 16 is connected to a water box connecting pipe 23 and a drain pipe 24. The water box connecting pipe 23 is connected to the water box 21, and the drain pipe 24 is used to discharge water from the water collector 18 outside the clothing processing equipment. When the water pump 17 is started, the inlet valve body 16 can be controlled to pump water from the water collector 18 to the cooler 8, to the water box 21, or to the drain pipe.

[0085] In an example where 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, with one end of each section connected via a water inlet valve body 16, the other end of the first water inlet pipe section 1501 connected to the water inlet of the cooler 8, the other end of the second water inlet pipe section 1502 connected to the water collector 18, a water pump 17 mounted on the second water inlet pipe section 1502, and the other end of the third water inlet pipe section 1503 connected to a water valve outside the garment processing equipment, please refer to [reference needed]. 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 out of the clothing processing equipment.

[0086] Please see 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.

[0087] 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.

[0088] Regarding the airflow duct, in one embodiment, please refer to Figure 10 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.

[0089] 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.

[0090] Please see Figure 10 This diagram illustrates that both the heater 6 and the first fan 7 are located on the first air intake duct 13, with the first fan 7 positioned at the front end of the airflow direction of the heater 6. Driven by the first fan 7, air from outside the garment processing equipment flows through the first air intake duct 13 and the heater 6 within the first air intake duct 13 towards the regeneration zone. Air passing through the regeneration zone is then discharged from the garment processing equipment through the first exhaust duct 14.

[0091] Specifically, a first air intake duct 13 and a first exhaust duct 14 are formed within the garment processing equipment. The air inlet of the first air intake duct 13 is formed on the housing of the garment processing equipment, and the air outlet of the first exhaust duct 14 is formed on the housing of the garment processing equipment. Preferably, 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.

[0092] In this embodiment, the position of the first fan 7 can be reasonably set according to the internal layout of the clothing processing equipment.

[0093] 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.

[0094] Please see Figure 10 The diagram 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 rotary dehumidification system is in operation, the air inlet damper 26 and the air outlet damper 27 are opened, i.e., 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 rotary dehumidification system is not in operation, the air inlet damper 26 and the air outlet damper 27 are closed, i.e., 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.

[0095] Preferably, 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.

[0096] 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 rotary dehumidification system is not working.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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 through the rotation of 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 dry the clothes inside the drum.

[0102] 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 single heat pump and dehumidification mode where the heat pump and dehumidifier work simultaneously. Alternatively, during the drying process, it can operate in a single heat pump system dehumidification mode, a heat pump and dehumidifier working simultaneously dehumidification mode, or a single moisture absorption and dehumidification system dehumidification mode at different time periods.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] Specifically, when the clothes drying 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 the third preset temperature value, for example, the third preset temperature 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 is not lower than the third preset temperature value, it controls only the heat pump system to work.

[0108] 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.

[0109] 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.

[0110] Specifically, 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.

[0111] 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.

[0112] Specifically, 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 moisture absorption and dehumidification system to work.

[0113] 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.

[0114] 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.

[0115] For example, in one scenario, 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 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 (t2 can be 2-5 minutes), the control device activates the dehumidification system; otherwise, it stops operating.

[0116] 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.

[0117] In existing 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 its 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.

[0118] 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.

[0119] 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.
