Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, specifically relating to a drying device and a clothing processing device. Background Technology

[0002] In related technologies, there is room for improvement in the drying efficiency of clothing processing equipment such as dryers or dryer-dryer combos. Summary of the Invention

[0003] This application provides a drying apparatus and a garment processing device, which aims to improve the drying efficiency of the garment processing device to at least a certain extent.

[0004] In a first aspect of this application, a drying apparatus is provided, comprising a moisture absorption and dehumidification module, a heat pump module, a heating component, and a cooler. The moisture absorption and dehumidification module has a dehumidification zone and a desorption zone. The heat pump module includes an evaporator and a condenser. The evaporator, the dehumidification zone of the moisture absorption and dehumidification module, and the condenser are sequentially connected along the airflow direction. The desorption zone of the moisture absorption and dehumidification module, the cooler, and the heating component are sequentially and cyclically connected.

[0005] When the drying device provided in this application is applied to clothing processing equipment, the humid airflow drawn from the air outlet of the equipment's cylinder undergoes partial moisture removal via the evaporator and is then adsorbed onto the dehumidification module's disc. As the disc rotates into the dehumidification zone, it further removes moisture from the humid airflow, forming a low-temperature dry airflow. This low-temperature dry airflow then passes through a condenser for heat exchange, generating a high-temperature dry airflow to dry the clothes. Because the moisture has been adsorbed in the dehumidification zone of the dehumidification module, the moisture content of the dry airflow is reduced, effectively improving the drying efficiency of the clothing processing equipment and reducing drying time. The moisture extracted by the desiccant module is stored in the desorption zone of the desiccant module and then released under the action of the heating element to generate a humid airflow. The humid airflow passes through the cooler to condense water, forming a medium-temperature, high-humidity airflow. The medium-temperature, high-humidity airflow is heated by the heating element to become a high-temperature, dry airflow. The high-temperature, dry airflow enters the desorption zone of the desiccant module, carrying away the moisture stored in the desorption zone and forming a humid airflow again. The humid airflow then enters the cooler again to condense water, generating medium-temperature, high-humidity gas again. This cycle continues to improve the drying efficiency of the clothing processing equipment.

[0047] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] In recent years, as people's pursuit of a better quality of life has increased, clothes drying equipment such as dryers and washer-dryer combos have gradually gained popularity among consumers in various regions due to their unique functionality. Currently, drying modes are mainly divided into condenser, exhaust, and heat pump types. Compared with the other two methods, heat pump drying reduces damage to clothes, improves their fluffiness, and recovers the latent and sensible heat of the airflow, resulting in lower energy consumption and making it widely popular.

[0049] Figure 1 and Figure 2 A schematic diagram of the garment processing device according to an embodiment of this application is shown. (In conjunction with...) Figure 1 and Figure 2 This is a clothing handling device for a dryer or washer-dryer combo, comprising a housing 1, a door 2, a drum 3, and a drying unit 4. The housing 1 has a loading port 101 on its front side, allowing the user to insert or remove clothing from the drum 3. The door 2 is rotatably connected to the front side of the housing 1 to open and close the loading port 101. The drum 3 is rotatably installed inside the housing 1 to hold clothing.

[0050] Such as 1 and Figure 2As shown, in one embodiment of this application, an air inlet 102 with an air inlet channel is arranged below the dispensing port 101, an air outlet channel 103 is arranged below the cylinder 3, and an air inlet channel 104 is provided on the back of the cylinder 3. The cylinder 3, the air outlet channel 103, and the air inlet channel 104 are connected in sequence to form an air duct for airflow circulation. A drying device 4 is installed inside the air outlet channel 103. The humid air discharged from the cylinder 3 enters the air outlet channel 103 from the air inlet 102 and is dried by the drying device 4 to form a clean, dry airflow. The air inlet channel 104 introduces the dry airflow into the cylinder 3 to dry the clothes inside the cylinder 3.

[0051] It is important to note that Figure 1 and Figure 2 This example illustrates the layout of a drying device 4, air outlet 103, air inlet 102, and air inlet 104 in a garment processing device for ease of understanding, and does not limit the position or relative relationship of these devices / components. For example, in another embodiment of this application, the drying device 4 is arranged above the drum 3, or the drying device 4 is arranged both above and below the drum 3 to process the humid airflow from the drum 3 into dry airflow. Accordingly, the air outlet 103 or air inlet 14 can be arranged above, below, or behind the drum 3. Due to the vast number of examples, they are not all listed here.

[0052] In related technologies, the drying device of a heat pump-type clothes drying system includes an evaporator, a condenser, and an induced draft fan arranged along the airflow direction. The evaporator and condenser constitute a heat pump module. Under the action of the induced draft fan, the humid air inside the drum flows towards the evaporator. After being cooled and dehydrated by the evaporator, it is heated by the condenser to form a dry airflow. This dry airflow flows into the drum to dry the clothes inside. However, in related technologies, clothes drying equipment suffers from a long drying time, indicating room for improvement in drying efficiency.

[0053] The reason is that during the operation of the clothing processing equipment, the humid airflow inside the drum still contains a lot of moisture after being cooled and dehydrated by the evaporator. After this moisture-containing airflow is heated by the condenser, the generated high-temperature airflow still contains too much moisture. This high-temperature airflow with too much moisture is guided into the drum to dry the clothes, affecting the drying efficiency of the clothes inside the drum, and thus causing the drying time to be longer.

[0054] In view of the above-mentioned technical problems, this application provides a drying device and a clothing processing equipment, which aims to improve the drying efficiency of the clothing processing equipment to at least a certain extent.

[0055] The design concept of this application is as follows: by adding a moisture-absorbing and dehumidifying module before guiding the high-temperature airflow into the drum, on the one hand, the moisture-absorbing and dehumidifying module can absorb moisture in the medium and low temperature airflow, reduce the moisture in the high-temperature airflow guided into the drum, improve the dryness of the high-temperature airflow, and thus improve the drying efficiency of the clothes in the drum and reduce the drying time; on the other hand, the moisture-absorbing and dehumidifying module can also release the absorbed moisture under the action of the heating component to generate a humid airflow, which can be reused to improve the drying efficiency of the clothes processing equipment.

[0056] Specific technical solutions will now be described in detail with reference to the accompanying drawings, which are not necessarily drawn to scale. Similar or identical reference numerals may be used to designate the same or similar parts in different figures. The use of similar or identical reference numerals in different figures does not mean that all figures including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this application in a generalized, illustrative, and not restrictive manner.

[0057] Based on the above design concept, in the first aspect of this application, this application provides a moisture absorption and dehumidification module, which is part of a drying device. Figure 3 A schematic diagram of the structure of a moisture absorption and dehumidification module according to one or more embodiments of this application is shown. Figure 4 It shows Figure 3 A structural diagram from another perspective. Combined with... Figure 3 as well as Figure 4 The moisture absorption and dehumidification module includes a regeneration housing 411 and a disc 412. Figure 5 It shows Figure 3 A schematic diagram of the structure of the regenerated shell 411 in the middle. Figure 6 It shows Figure 5 Another perspective of the results diagram, combined with Figure 5 as well as Figure 6 The regeneration shell 411 is provided with a receiving cavity 4111, which is provided with a dehumidification zone 4112 and a desorption zone 4113 at intervals. The wheel 412 is rotatably disposed in the receiving cavity 4111. When the wheel 412 rotates to the dehumidification zone 4112, the wheel 412 adsorbs moisture in the humid airflow. When the wheel 412 rotates to the desorption zone 4113, the moisture adsorbed by the wheel 412 is released under the action of the heating component 44.

[0058] When the moisture absorption and dehumidification module provided in this application is applied to a drying equipment, the humid airflow drawn from the air outlet of the drying equipment cylinder 3 is partially dehydrated by the evaporator 5 and then adsorbed onto the dehumidification module's disc 412. When the disc 412 rotates to the dehumidification zone 4112, the disc 412 further dehydrates the moisture in the humid airflow, forming a low-temperature dry airflow. The low-temperature dry airflow then undergoes heat exchange in the condenser 6 to generate a high-temperature dry airflow for drying clothes. Because the moisture has been adsorbed by the dehumidification zone 4112 of the disc 412, the moisture content of the dry airflow can be reduced, effectively improving the drying efficiency of the clothing processing equipment and reducing the drying time. When the disc 412 rotates to the desorption zone 4113, the moisture adsorbed by the disc 412 is dehydrated under the action of the heating component 44 to generate a humid airflow. The humid airflow is again adsorbed by the evaporator 5 and the disc 412, and heated by the condenser 6 to generate a high-temperature dry airflow for reuse, thereby improving the drying efficiency of the clothing processing equipment. The specific details of the moisture absorption and dehumidification module are now described in further detail with reference to the accompanying drawings.

[0059] Combination Figure 5 as well as Figure 6 According to one embodiment of this application, the moisture absorption and dehumidification module further includes a separator 4114, with both ends of the separator 4114 connected to the inner wall of the receiving cavity 4111, and the middle part of the separator 4114 extending toward the middle part of the receiving cavity 4111, dividing the receiving cavity 4111 into the aforementioned dehumidification zone 4112 and desorption zone 4113.

[0060] Combination Figure 5 as well as Figure 6 According to one embodiment of this application, the separator 4114 is also generally U-shaped. The inner wall of the separator 4114 and the inner wall of the receiving cavity 4111 are configured to form a desorption zone 4113, and the outer wall of the separator 4114 and the inner wall of the receiving cavity 4111 are configured to form a dehumidification zone 4112. That is, the receiving cavity 4111 is divided into the aforementioned dehumidification zone 4112 and desorption zone 4113 by the separator 4114. The volume of the desorption zone 4113 is smaller, and the volume of the dehumidification zone 4112 is larger. The dehumidification zone 4112 is used as the main airflow passage, and the desorption zone 4113 is used as an auxiliary airflow passage. The volume of the desorption zone 4113 is about one-third of the volume of the dehumidification zone 4112 to ensure the airflow of the main airflow passage, thereby ensuring the airflow of the clothes in the drying drum 3 and ensuring the drying effect of the clothes in the drum 3.

[0061] Combination Figure 3The dehumidification module also includes a drive component 42, which is connected to the wheel 412 to drive the wheel 412 to rotate within the receiving cavity 4111. Under the action of the drive component 42, the wheel 412 and the support component 414 rotate synchronously within the receiving cavity 4111. When the wheel 412 rotates to the dehumidification zone 4112, it adsorbs moisture from the humid airflow; when it rotates to the desorption zone 4113, the moisture adsorbed by the wheel 412 is released under the action of the heating component 44.

[0062] Combination Figure 3 as well as Figure 4 According to one embodiment of this application, the moisture absorption and dehumidification module further includes an air hood 43 connected to the desorption zone 4113. The air hood 43 can draw out the warm humid airflow to a suitable location to reuse the portion of the warm humid airflow and improve drying efficiency.

[0063] Figure 7 It shows Figure 2 A schematic diagram of the heating component 44 is shown. (Combined with...) Figure 7 According to one embodiment of this application, the heating component 44 is connected upstream of the desorption zone 4113. When the wheel 412 rotates to the desorption zone 4113, the moisture adsorbed by the wheel 412 is released under the action of the heating component 44. The heating component 44 includes a heating housing 441, a heating element 442, and a first air duct 443. The heating housing 441 is connected to the air duct of the desorption zone 4113. The heating element 442 and the first air duct 443 are disposed inside the heating housing 441. The first air duct 443 draws in outside air, which is heated by the heating element 442 to generate high-temperature air. When the wheel 412 rotates to the dehumidification zone 4112, the high-temperature air releases the water adsorbed by the wheel 412 to form a humid airflow with temperature. This humid airflow is drawn out from the return air duct of the dehumidification zone 4112.

[0064] Combination Figure 7 In one embodiment, the first air-guiding element 443 and the heating element 442 are sequentially positioned close to the desorption zone 4113. The first air-guiding element 443 can be a fan, with the fan housing extending to the air inlet of the desorption zone 4113. The heating element 442 can be a disc structure, placed within a heating housing 441 between the fan impeller and the air inlet. In another embodiment, the heating element 442 and the first air-guiding element 443 are positioned exceptionally close to the air inlet; this application does not impose any restrictions on this.

[0065] Based on the same design concept, in a second aspect of this application, a drying device 4 is also provided. Figure 8 A schematic diagram of airflow in a garment handling device according to one or more embodiments of this application is shown. (In conjunction with...) Figure 8In one embodiment, the drying device 4 includes a heat pump module, a cooler 7, the aforementioned moisture absorption and dehumidification module 41, and a heating component 44. The heat pump module includes an evaporator 5 and a condenser 6. Along the airflow direction, the evaporator 5, the dehumidification zone 4112 of the moisture absorption and dehumidification module 41, and the condenser 6 are connected in sequence. The desorption zone 4113 of the moisture absorption and dehumidification module 41, the cooler 7, and the heating component 44 are connected in a cyclical manner.

[0066] When the drying device 4 provided in this application is applied to clothing processing equipment, the humid airflow drawn from the air outlet of the equipment's drum 3 passes through the evaporator 5, where a portion of the moisture is extracted. The extracted moisture is then adsorbed onto the disc 412 of the dehumidification module 41. As the disc 412 rotates to the dehumidification zone 4112, it further extracts moisture from the humid airflow, forming a low-temperature dry airflow. This low-temperature dry airflow then undergoes heat exchange in the condenser 6, generating a high-temperature dry airflow. This high-temperature dry airflow is introduced into the drum 3 to dry the clothing. Because the moisture has been adsorbed by the dehumidification zone 4112 of the dehumidification module 41, the moisture content of the dry airflow is reduced, effectively improving the drying efficiency of the clothing processing equipment. Reduce drying time; the moisture adsorbed by the moisture absorption and dehumidification module 41 is stored in the desorption zone 4113 of the moisture absorption and dehumidification module 41, and is released under the action of the heating component 44 to generate a humid airflow. The humid airflow passes through the cooler 7 to condense water, forming a medium-temperature high-humidity airflow. The medium-temperature high-humidity airflow is heated by the heating component 44 to become a high-temperature dry airflow. The high-temperature dry airflow enters the desorption zone 4113 of the moisture absorption and dehumidification module 41, takes away the moisture stored in the desorption zone 4113 of the moisture absorption and dehumidification module 41, and forms a humid airflow again. The humid airflow enters the cooler 7 again to condense water, and generates medium-temperature high-humidity gas again. This cycle continues, thereby improving the drying efficiency of the clothing processing equipment.

[0067] It should be noted that the evaporator 5, the dehumidification zone 4112 of the moisture absorption and dehumidification module 41, and the condenser 6 can be arranged in the same air duct; the desorption zone 4113 of the moisture absorption and dehumidification module 41, the cooler 7, and the heating component 44 can be arranged in another air duct to ensure that the airflow flows in the preset direction. In addition, the sequential and cyclic connection of the desorption zone 4113, the cooler 7, and the heating component 44 of the moisture absorption and dehumidification module 41 means that the desorption zone 4113 of the moisture absorption and dehumidification module 41 is connected to the cooler 7 and the heating component 44 respectively, and the cooler 7 is connected to the heating component 44 to form an airflow circulation.

[0068] Combination Figure 8The drying device also includes a compressor 8 and a throttling device 9. Along the refrigerant flow direction, the compressor 8, condenser 6, throttling device 9, evaporator 5, and cooler 7 are sequentially connected in a cycle. In specific implementation, the high-temperature and high-pressure gaseous refrigerant releases heat after passing through the condenser 6 and becomes a high-pressure and medium-temperature liquid refrigerant. The high-pressure and medium-temperature liquid refrigerant is cooled and depressurized by the throttling device 9 into a low-temperature and low-pressure gas-liquid two-phase refrigerant. The low-temperature and low-pressure gas-liquid two-phase refrigerant enters the evaporator 5 to absorb heat and then enters the cooler 7 to continue absorbing heat. Finally, it is compressed by the compressor 8 into a high-temperature and high-pressure gaseous refrigerant, and the cycle repeats.

[0069] It should be noted that the sequential connection of compressor 8, condenser 6, throttling device 9, evaporator 5 and cooler 7 along the refrigerant flow direction means that the output part of compressor 8, condenser 6, throttling device 9, evaporator 5 and cooler 7 are connected in sequence along the refrigerant flow direction, and cooler 7 is connected to the input part of compressor 8 to form a refrigerant circuit.

[0070] Figure 9 A schematic diagram of airflow in a garment handling device according to another embodiment is shown, in conjunction with Figure 9 , Figure 9 The garment processing equipment shown Figure 8 The main difference in the garment processing equipment shown lies in the order in which the refrigerant enters the evaporator 5 and condenser 6 after passing through the throttling device 9. Other details can be found in the description of the garment processing equipment above. Specifically, along the refrigerant flow direction, the compressor 8, condenser 6, throttling device 9, cooler 7, and evaporator 5 are connected in a sequential cycle. The high-temperature, high-pressure gaseous refrigerant releases heat after passing through the condenser 6, becoming a high-pressure, medium-temperature liquid refrigerant. This high-pressure, medium-temperature liquid refrigerant is cooled and depressurized by the throttling device 9, becoming a low-temperature, low-pressure gas-liquid two-phase refrigerant. This low-temperature, low-pressure gas-liquid two-phase refrigerant enters the cooler 7 to absorb heat, then enters the evaporator 5 to continue absorbing heat. Finally, it is compressed by the compressor 8 into a high-temperature, high-pressure gaseous refrigerant, and the cycle repeats continuously.

[0071] It should be noted that the sequential connection of compressor 8, condenser 6, throttling device 9, cooler 7 and evaporator 5 along the refrigerant flow direction means that the output part of compressor 8, condenser 6, throttling device 9, cooler 7 and evaporator 5 are connected in sequence along the refrigerant flow direction, and evaporator 5 is connected to the input part of compressor 8 to form a refrigerant circuit.

[0072] Figure 8 In the clothing processing equipment shown, the refrigerant is mainly used for dehumidification in evaporator 5; Figure 9 In the clothing processing equipment shown, the refrigerant is mainly used for dehumidification of the cooler 7, and can be adaptively selected according to the specific temperature requirements of the drum 3; this application does not impose any limitations on this. Furthermore, according to one embodiment of this application, Figure 8 and Figure 9In the clothing processing device shown, the liquid water condensed on the surface of the evaporator 5 and the liquid water condensed on the surface of the cooler 7 can be directly discharged by a drain pump or stored in a water box. This application does not impose any restrictions on this.

[0073] Figure 10 A schematic diagram of the airflow of the garment processing device in the third embodiment of this application is shown, in conjunction with... Figure 10 , Figure 10 The main difference between the clothing processing device shown and the clothing processing device described above is that the refrigerant, after passing through the throttling component 9, can be controlled to enter at least one of the evaporator 5 and condenser 6 of the heat pump module, so that the clothing processing device can have different dehumidification modes, that is, perform at least one of heat pump dehumidification and moisture absorption dehumidification module dehumidification. For further details, please refer to the relevant description of the clothing processing device described above. Specifically, the compressor 8 has an output section and an input section. The output section of the compressor 8, the condenser 6, and the throttling component 9 are connected in sequence. The throttling component 9 can be controlled to be connected to at least one of the cooler 7 and the evaporator 5. Both the cooler 7 and the evaporator 5 are connected to the input section of the compressor 8. The compressor 8 outputs high-temperature, high-pressure gaseous refrigerant. This high-temperature, high-pressure gaseous refrigerant releases heat after passing through the condenser 6, becoming a high-pressure, medium-temperature liquid refrigerant. This high-pressure, medium-temperature liquid refrigerant then passes through the throttling device 9, where it is cooled and depressurized into a low-temperature, low-pressure gas-liquid two-phase refrigerant. This low-temperature, low-pressure gas-liquid two-phase refrigerant then enters at least one of the evaporator 5 and the cooler 7, absorbs heat, and then enters the compressor 8 to be compressed into a high-temperature, high-pressure gaseous refrigerant, repeating the cycle. The refrigerant, after passing through the throttling device 9, can be controlled to enter at least one of the evaporator 5 and the condenser 6, allowing the garment processing equipment to have different dehumidification modes. Refer to the relevant description of the control method below.

[0074] Combination Figure 10 According to one embodiment of this application, the drying device further includes a first valve body 12 and a second valve body 13. The first valve body 12 is disposed between the throttling component 9 and the evaporator 5 to control the on / off state between the throttling component 9 and the evaporator 5. The second valve body 13 is disposed between the throttling component 9 and the cooler 7 to control the on / off state between the throttling component 9 and the cooler 7. Both the first valve body 12 and the second valve body 13 can be one-way valves to prevent refrigerant backflow.

[0075] Combination Figure 10 In one embodiment, one end of the first valve body 12 is connected between the throttling component 9 and the second valve body 13, and the other end of the first valve body 12 is connected to the evaporator 5. This arrangement can save some of the refrigerant pipeline. In another embodiment, the first valve body 12 and the second valve body 13 can also both be connected to the throttling component 9 through corresponding refrigerant pipelines. This application does not limit this.

[0076] Combination Figure 8 , Figure 9 as well as Figure 10 In a third aspect of this application, this application also provides a garment processing device, which includes a drum 3, the drum 3 being provided with an air outlet and an air inlet, and the aforementioned drying device 4 being connected to the air outlet and the air inlet of the drum 3 respectively.

[0077] The garment processing equipment provided in this application can be a dryer or a washer-dryer combo, which can reduce the moisture in the drying airflow introduced into the drum 3, effectively improve the drying efficiency of the garment processing equipment, reduce drying time, and has good practicality.

[0078] Combination Figure 8 , Figure 9 as well as Figure 10 According to one embodiment of this application, the garment processing device further includes a second air duct 10, which is disposed downstream of the condenser 6 along the airflow direction. In another embodiment, the second air duct 10 may also be disposed upstream of the evaporator 5, so that the airflow is circulated between the drying device 44 and the drum 33 of the garment processing device under the action of the second air duct 10.

[0079] Combination Figure 8 , Figure 9 as well as Figure 10 According to one embodiment of this application, the garment processing device further includes a filter element 11, which is disposed between the air outlet of the drum 3 and the evaporator 5 to filter lint in the airflow drawn from the drum, so as to prevent lint from being introduced into the drying device 4 and affecting the operation of the drying device 4.

[0080] The garment processing equipment provided in this application can be a dryer or a washer-dryer combo. It can reduce the moisture in the drying airflow introduced into the drum 3, effectively improving the drying efficiency of the garment processing equipment, reducing drying time, and thus having excellent practicality. As for the corresponding structure of the garment processing equipment, please refer to the above description; it will not be repeated here.

[0081] Figure 8 as well as Figure 9 The garment processing equipment shown in this application can shorten the drying time by 10% to 15% compared to conventional garment processing equipment that only has an evaporator 5 and a condenser 6 when the drum 3 is at a normal ambient temperature (20-25°C); when the drum 3 is at a low ambient temperature (below 10°C), the garment processing equipment shown in this application can shorten the drying time by 20% to 30% compared to conventional garment processing equipment that only has a heat pump dehumidification module with an evaporator 5 and a condenser 6.

[0082] In a fourth aspect, this application also provides a control method for the clothing processing device shown in Embodiment 3. Figure 11 A flowchart illustrating the control method of the garment processing equipment of this application is shown, in conjunction with... Figure 11 The control method includes:

[0083] S1: Obtain the real-time temperature inside the cylinder and compare the real-time temperature with the set temperature. The real-time temperature inside the cylinder can be obtained by a temperature sensor installed inside the cylinder.

[0084] S2: When the real-time temperature is lower than the set temperature, the control throttling component 9 is connected to the cooler 7 and the evaporator 5, that is, the control first valve body 12 and the second valve body 13 are opened. The clothing processing equipment performs heat pump dehumidification and moisture absorption and dehumidification module 41 dehumidification. The heat pump system composed of evaporator 5 and condenser 6 and the moisture absorption and dehumidification module 41 work at the same time, which can efficiently increase the temperature inside the drum, avoid the temperature preheating time in the initial stage, shorten the drying time, and improve the drying efficiency.

[0085] S3: When the real-time temperature is greater than or equal to the set temperature, confirm the drying time of the clothing processing equipment;

[0086] S31: When the clothing processing equipment is in the early stage of drying, the throttling component 9 is connected to the evaporator 5 and the throttling component 9 is disconnected from the cooler 7. That is, the first valve body 12 is opened and the second valve body 13 is closed. The clothing processing equipment performs heat pump dehumidification. It can work through a heat pump system with stronger dehumidification capacity to ensure that the temperature inside the drum rises quickly to improve drying efficiency.

[0087] S32: When the clothing processing equipment is in the later stage of drying, the throttling component 9 is connected to the cooler 7 and the throttling component 9 is disconnected from the evaporator 5. The clothing processing equipment executes the dehumidification module 41 for dehumidification, that is, the first valve body 12 is closed and the second valve body 13 is opened. The clothing processing equipment executes the dehumidification module 41 for dehumidification. Since the air humidity is low, the dehumidification capacity of the heat pump system is weakened. Therefore, the dehumidification is carried out by the disc of the dehumidification module 41 to ensure the internal temperature of the drum and the drying efficiency.

[0088] The control method for the garment processing equipment provided in this application can control the opening and closing of the valve body to put the garment processing equipment into different dehumidification modes to adapt to different drum temperatures, ensure the internal temperature of the drum, and improve drying efficiency.

[0089] Figure 10The garment processing equipment shown in this application can shorten the drying time by 8% to 10% compared to conventional garment processing equipment that only has an evaporator 5 and a condenser 6 when the drum 3 is at a normal ambient temperature (20-25°C); when the drum 3 is at a low ambient temperature (below 10°C), the garment processing equipment shown in this application can shorten the drying time by 20% to 30% compared to conventional garment processing equipment that only has an evaporator 5 and a condenser 6.
