Description

Technical Field

[0001] The present application belongs to the technical field of electrical equipment, and specifically relates to a drying device and a clothing processing device. Background Art

[0002] In the related art, there is room for improvement in the drying efficiency of clothing processing appliances such as clothes dryers or integrated dryers. Summary of the Invention

[0003] The present application provides a drying device and a clothes processing device, aiming to improve the drying efficiency of the clothes processing device to at least a certain extent.

[0004] In the first aspect of the present application, a drying device is provided, comprising a dehumidification module, a heat pump module, a heating component and a cooler, wherein the dehumidification module has a dehumidification zone and a desorption zone separated by a partition, and the heat pump module comprises an evaporator and a condenser, wherein, along the air flow direction, the evaporator, the dehumidification zone of the dehumidification module and the condenser are connected in sequence, and the desorption zone of the dehumidification module, the cooler and the heating component are cyclically connected in sequence; it also comprises a compressor and a throttling component, the compressor having an output part and an input part, the output part of the compressor, the condenser and the throttling component are connected in sequence, and the throttling component can be controllably connected to at least one of the cooler and the evaporator, and the cooler and the evaporator are both connected to the input part of the compressor, so that the drying device performs at least one of heat pump dehumidification and dehumidification module dehumidification.

[0005] When the drying device provided by the present application is applied to a clothing processing device, the humid air flow drawn out from the air outlet of the cylinder of the device passes through the evaporator to precipitate a part of the moisture, and then is adsorbed onto the moisture absorption and dehumidification module. The dehumidification area of ​​the moisture absorption and dehumidification module can further precipitate the moisture in the humid air flow to form a low-temperature dry air flow. The low-temperature dry air flow then exchanges heat with the condenser to generate a high-temperature dry air flow to dry the clothes. Since the moisture is adsorbed by the dehumidification area of ​​the moisture absorption and dehumidification module, the moisture content of the dry air flow can be reduced, which can effectively improve the drying efficiency of the clothing processing device and reduce the drying time. The moisture precipitated by the dehumidification module is stored in the desorption area of ​​the moisture absorption and dehumidification module, and is precipitated under the action of the heating component to generate a humid air flow. The humid air flow passes through the cooler to precipitate condensed water to form a medium-temperature and high-humidity air flow. The medium-temperature and high-humidity air flow is heated by the heating component to be a high-temperature dry air flow. The high-temperature dry air flow enters the desorption area of ​​the moisture absorption and dehumidification module, takes away the moisture stored in the desorption area of ​​the moisture absorption and dehumidification module, and forms a humid air flow again. The humid air flow enters the cooler again to precipitate condensed water to generate medium-temperature and high-humidity gas again. This cycle is repeated, thereby improving the drying efficiency of the clothing processing equipment.

[0006] In addition, since the throttling component can be controllably connected to at least one of the cooler and the evaporator, with such a setting, the working states of the evaporator and the cooler can be controlled by controlling the connection between the throttling component and the cooler and the evaporator, so that the clothing processing equipment can execute different dehumidification modes, that is, execute at least one of heat pump dehumidification and moisture absorption dehumidification module dehumidification to adapt to different stages of the clothing processing program of the clothing processing equipment to ensure drying efficiency.

[0007] In some embodiments, a first valve body and a second valve body are further included, wherein the first valve body is disposed between the throttling component and the evaporator, and the second valve body is disposed between the throttling component and the cooler.

[0008] In some embodiments, the first valve body is connected between the throttling component and the second valve body.

[0009] In some embodiments, the first valve body and the second valve body are both one-way valves.

[0010] In some embodiments, the heating assembly includes a first air inducing member and a heating member.

[0011] In some embodiments, along the air flow direction, the cooler, the first air inducing member, the heating member, and the desorption zone of the moisture absorption and dehumidification module are connected in sequence.

[0012] In some embodiments, along the air flow direction, the cooler, the heating element, the first air inducing element, and the desorption area of ​​the moisture absorption and dehumidification module are connected in sequence.

[0013] In the second aspect of the present application, the present application also provides a clothing processing device, which includes: a drum, provided with an air outlet and an air inlet; the above-mentioned drying device, respectively connected to the air outlet and air inlet of the drum.

[0047] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0048] In recent years, as people's pursuit of a better quality of life continues to grow, clothes dryers, washer-dryers, and other clothing processing appliances have gradually gained popularity among consumers across various regions due to their unique functionality. Currently, clothes drying methods are mainly divided into condensing, exhaust, and heat pump drying modes. Compared with the other two drying methods, heat pump drying mode reduces damage to clothes, improves the fluffiness of clothes, and recovers the latent and sensible heat of the airflow, resulting in lower energy consumption and a popular choice.

[0049] Figure 1 and Figure 2 The figure shows a schematic structural diagram of a clothes processing device according to an embodiment of the present application. Figure 1 and Figure 2The clothing processing device, which can be a clothes dryer or a washer-dryer, includes a housing 1, a door 2, a drum 3, and a drying device 4. The housing 1 has a loading port 101 on the front side, which allows a user to put clothes into or take clothes out of 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 mounted inside the housing 1 to accommodate clothes.

[0050] As 1 and Figure 2 As shown, in one embodiment of the present application, an air inlet 102 of an air inlet channel is disposed below the inlet port 101, an air outlet 103 is disposed below the drum 3, and an air inlet 104 is disposed on the back of the drum 3. The drum 3, the air outlet 103, and the air inlet 104 are sequentially connected to form an air duct for air circulation. The air outlet 103 houses a drying device 4. After the humid air discharged from the drum 3 enters the air outlet 103 from the air inlet 102, it is dried by the drying device 4 to form a clean, dry airflow. The air inlet 104 introduces the dry airflow into the drum 3 to dry the clothes inside.

[0051] It should be noted that Figure 1 and Figure 2 The layout of a drying device 4, an air outlet duct 103, an air inlet 102, and an air inlet duct 104 in a clothing processing device is provided for the convenience of the reader, and does not limit the positions and relative relationships of these devices / components. For example, another embodiment of the present application is to configure a drying device 4 above the drum 3, or to provide a drying device 4 above and below the drum 3 to process the wet air flow out of the drum 3 into a dry air flow. Accordingly, the air outlet duct 103 or the air inlet duct 14 can be provided above, below, or behind the drum 3. The number of examples is too large to list here, and they are not listed one by one.

[0052] In related art, the drying device of heat pump drying equipment includes an evaporator, a condenser, and an induced draft fan arranged along the airflow direction. The evaporator and condenser form a heat pump module. The induced draft fan drives the moist air in the drum toward the evaporator. After being cooled and dehydrated by the evaporator, it is heated by the condenser to form a dry airflow, which flows into the drum to dry the clothes inside. In related art, the drying process of clothing processing equipment suffers from a long drying time, leaving room for improvement in the drying efficiency of these equipment.

[0053] The reason is that during the operation of the clothing processing equipment, the humid air in the drum still contains a lot of water after being cooled and dehydrated by the evaporator. After these water-containing air flows are heated by the condenser, there is still too much water in the generated high-temperature air flow. The high-temperature air flow containing too much water is guided into the drum to dry the clothes, affecting the drying efficiency of the clothes in the drum, and then causing the drying time to be prolonged.

[0054] Based on the above technical problems, the present application provides a drying device and a clothing processing equipment, aiming to improve the drying efficiency of the clothing processing equipment to at least a certain extent.

[0055] The design idea of ​​this application is: by adding a moisture absorption and dehumidification module before guiding the high-temperature airflow into the drum, on the one hand, the moisture absorption and dehumidification module can absorb moisture in medium and low temperature airflows, reduce the moisture in the high-temperature airflow guided into the drum, and improve the dryness of the high-temperature airflow, thereby improving the drying efficiency of the clothes in the drum and reducing the drying time; on the other hand, the moisture absorption and dehumidification module can also precipitate the adsorbed moisture under the action of the heating component to generate a humid airflow, which is reused to improve the drying efficiency of the clothing processing equipment.

[0056] The 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 imply that all figures including similar or identical reference numerals constitute a single or identical embodiment. The accompanying drawings generally illustrate various embodiments discussed in this application by way of example and not limitation.

[0057] Based on the above design ideas, in the first aspect of the present application, the present application provides a moisture absorption and dehumidification module, which is part of a drying device. Figure 3 shows a schematic structural diagram of a moisture absorption and dehumidification module in one or more embodiments of the present application, Figure 4 Shown Figure 3 Another structural diagram of the perspective. Figure 3 as well as Figure 4 The moisture absorption and dehumidification module includes a regeneration shell 411 and a wheel 412. Figure 5 Shown Figure 3 The structural diagram of the regeneration shell 411, Figure 6 Shown Figure 5 Schematic diagram of the results from another perspective, combined with Figure 5 as well as Figure 6The regeneration shell 411 is provided with a accommodating chamber 4111, and the accommodating chamber 4111 is provided with a dehumidification zone 4112 and a desorption zone 4113 at intervals. The wheel 412 is rotatably provided in the accommodating chamber 4111, wherein when the wheel 412 rotates to the dehumidification zone 4112, the wheel 412 absorbs moisture in the humid air flow; when the wheel 412 rotates to the desorption zone 4113, the moisture adsorbed by the wheel 412 is precipitated under the action of the heating component 44.

[0058] When the moisture absorption and dehumidification module provided in the present application is applied to a drying device, the humid air flow drawn out from the air outlet of the cylinder 3 of the drying device passes through the evaporator 5 to precipitate a part of the moisture, and is then adsorbed onto the wheel 412 of the humid air flow. When the wheel 412 rotates to the dehumidification zone 4112, the wheel 412 further precipitates moisture in the humid air flow to form a low-temperature dry air flow. The low-temperature dry air flow then exchanges heat through the condenser 6 to generate a high-temperature dry air flow to dry clothes. Since the moisture has been adsorbed by the dehumidification zone 4112 of the wheel 412, the moisture in the dry air flow can be reduced, which can effectively improve the drying efficiency of the clothing processing equipment and reduce the drying time; when the wheel 412 rotates to the desorption zone 4113, the moisture adsorbed by the wheel 412 is precipitated under the action of the heating component 44 to generate a humid air flow. The humid air flow is again adsorbed by the evaporator 5 and the wheel 412 and heated by the condenser 6 to generate a high-temperature dry air flow for reuse, thereby improving the drying efficiency of the clothing processing equipment. The specific details of the moisture absorption and dehumidification module are now further described with reference to the accompanying drawings.

[0059] Combine Figure 5 as well as Figure 6 According to one embodiment of the present application, the moisture absorption and dehumidification module also includes a partition 4114, the two ends of the partition 4114 are respectively connected to the inner wall of the accommodating chamber 4111, and the middle part of the partition 4114 extends toward the middle part of the accommodating chamber 4111. The partition 4114 divides the accommodating chamber 4111 into the above-mentioned dehumidification zone 4112 and desorption zone 4113.

[0060] Combine Figure 5 as well as Figure 6According to one embodiment of the present application, the partition 4114 is also roughly U-shaped, and the inner wall of the partition 4114 and the inner wall of the accommodating chamber 4111 are configured to form a desorption zone 4113, and the outer wall of the partition 4114 and the inner wall of the accommodating chamber 4111 are configured to form a dehumidification zone 4112, that is, the accommodating chamber 4111 is divided into the above-mentioned dehumidification zone 4112 and desorption zone 4113 by the partition 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 air flow passage, and the desorption zone 4113 is used as the auxiliary air flow passage. The volume of the desorption zone 4113 is approximately one-third of the volume of the dehumidification zone 4112, so as to ensure the air flow of the main air flow passage, and then ensure the air flow of the clothes in the drying cylinder 3, thereby ensuring the drying effect of the clothes in the cylinder 3.

[0061] Combine Figure 3 The moisture absorption and dehumidification module further includes a driving member 42 connected to the wheel disc 412 to drive the wheel disc 412 to rotate within the accommodating chamber 4111. Specifically, under the action of the driving member 42, the wheel disc 412 and the supporting member 414 rotate synchronously within the accommodating chamber 4111. When the wheel disc 412 rotates to the dehumidification zone 4112, it absorbs moisture from the humid air flow. When the wheel disc 412 rotates to the desorption zone 4113, the moisture absorbed by the wheel disc 412 is precipitated by the heating assembly 44.

[0062] Combine Figure 3 as well as Figure 4 According to one embodiment of the present application, the moisture absorption and dehumidification module further includes an air hood 43, which is connected to the desorption zone 4113. The air hood 43 can lead the warm humid air flow to a suitable position to reuse this part of the warm humid air flow to improve the drying efficiency.

[0063] Figure 7 Shown Figure 2 Schematic diagram of the structure of the heating component 44. Figure 7 According to one embodiment of the present application, the heating component 44 is connected to the upstream of the desorption zone 4113. When the wheel 412 rotates to the desorption zone 4113, the moisture adsorbed by the wheel 412 is precipitated under the action of the heating component 44. The heating component 44 includes a heating shell 441, a heating element 442, and a first air induction member 443. The heating shell 441 is connected to the air inlet of the desorption zone 4113. The heating element 442 and the first air induction member 443 are arranged in the heating shell 441. The first air induction member 443 draws in external air and generates high-temperature air after being heated by the heating element 442. When the wheel 412 rotates to the dehumidification zone 4112, the high-temperature air precipitates the moisture adsorbed by the wheel 412 to form a humid air flow with temperature, which is drawn out from the return air outlet of the dehumidification zone 4112.

[0064] Combine Figure 7 In one embodiment, first air inducing member 443 and heating member 442 are positioned adjacent to desorption zone 4113. First air inducing member 443 may be a fan, the fan housing extending to the air inlet of desorption zone 4113. Heating member 442 may be a disk structure positioned within heating housing 441 between the fan's impeller and the air inlet. In another embodiment, heating member 442 and first air inducing member 443 are positioned adjacent to the air inlet, which is not a limitation of this application.

[0065] Based on the same design concept, in the second aspect of the present application, the present application also provides a drying device 4. Figure 8 Schematic diagram of air flow of a clothes treating apparatus in one or more embodiments of the present application is shown. Figure 8 In one embodiment, the drying device 4 includes a heat pump module, a cooler 7, the above-mentioned 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 air flow direction, the evaporator 5, the dehumidification zone 4112 of the moisture absorption and dehumidification module 41 and the condenser 6 are connected in sequence, and the desorption zone 4113 of the moisture absorption and dehumidification module 41, the cooler 7 and the heating component 44 are cyclically connected in sequence.

[0066] When the drying device 4 provided in the present application is applied to a clothing processing device, the humid air flow drawn out from the air outlet of the drum 3 of the device passes through the evaporator 5 to precipitate a portion of the moisture, and then is adsorbed onto the wheel 412 of the moisture absorption and dehumidification module 41. When the wheel 412 rotates to the dehumidification area 4112, the wheel 412 further precipitates moisture in the humid air flow to form a low-temperature dry air flow. The low-temperature dry air flow then exchanges heat with the condenser 6 to generate a high-temperature dry air flow. The high-temperature dry air flow is introduced into the drum 3 to dry the clothes. Since the moisture passes through the dehumidification area 4112 of the moisture absorption and dehumidification module 41, the moisture content of the dry air flow can be reduced, which can effectively improve the drying efficiency of the clothing processing device. Reduce drying time; the moisture adsorbed by the moisture absorption and dehumidification module 41 is stored in the desorption area 4113 of the moisture absorption and dehumidification module 41, and is precipitated under the action of the heating component 44 to generate a moist air flow, and the moist air flow passes through the cooler 7 to precipitate condensed water to form a medium-temperature and high-humidity air flow, and the medium-temperature and high-humidity air flow is heated by the heating component 44 to be a high-temperature dry air flow, and the high-temperature dry air flow enters the desorption area 4113 of the moisture absorption and dehumidification module 41, takes away the moisture stored in the desorption area 4113 of the moisture absorption and dehumidification module 41, and forms a moist air flow again, and the moist air flow enters the cooler 7 again to precipitate condensed water to generate a medium-temperature and high-humidity gas again, and so on. The cycle then improves the drying efficiency of the clothing processing equipment.

[0067] It should be noted that the evaporator 5, the dehumidification zone 4112 of the dehumidification module 41 and the condenser 6 can be arranged in the same air duct; the desorption zone 4113 of the 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 a preset direction. In addition, the desorption zone 4113 of the dehumidification module 41, the cooler 7 and the heating component 44 are connected in a cycle in sequence, which means that the desorption zone 4113 of the 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 cycle.

[0068] Combine Figure 8 The drying device also includes a compressor 8 and a throttling component 9. Along the refrigerant flow direction, the compressor 8, condenser 6, throttling component 9, evaporator 5, and cooler 7 are connected in a circular manner. In specific implementation, the high-temperature and high-pressure gaseous refrigerant releases heat through the condenser 6 and becomes a high-pressure, medium-temperature liquid refrigerant. The high-pressure, medium-temperature liquid refrigerant is cooled and reduced in pressure by the throttling component 9 to become a low-temperature, low-pressure gas-liquid two-phase refrigerant. The low-temperature, 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, high-pressure gaseous refrigerant, and the cycle repeats.

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

[0070] Figure 9 A schematic diagram of air flow in a clothes processing apparatus according to another embodiment is shown. Figure 9 , Figure 9 The laundry treatment device shown and Figure 8 The main difference between the clothing processing devices shown is the order in which the refrigerant enters the evaporator 5 and condenser 6 after passing through the throttling component 9. For other reasons, please refer to the relevant description of the clothing processing devices mentioned above. Specifically, along the direction of refrigerant flow, the compressor 8, condenser 6, throttling component 9, cooler 7 and evaporator 5 are connected in a circular manner. After the high-temperature and high-pressure gaseous refrigerant releases heat through the condenser 6, it becomes a high-pressure, medium-temperature liquid refrigerant. The high-pressure, medium-temperature liquid refrigerant is cooled and reduced in pressure by the throttling component 9 to become a low-temperature, low-pressure gas-liquid two-phase refrigerant. The low-temperature, low-pressure gas-liquid two-phase refrigerant enters the cooler 7 to absorb heat and then enters the evaporator 5 to continue absorbing heat. Finally, it is compressed by the compressor 8 to become a high-temperature, high-pressure gaseous refrigerant, and the cycle repeats.

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

[0072] Figure 8 In the clothes processing apparatus shown, the refrigerant is mainly used for dehumidification in the evaporator 5; Figure 9 In the clothes processing device shown, the refrigerant is mainly used for dehumidification of the cooler 7, which can be adaptively selected according to the specific temperature requirements of the barrel 3, and this application does not limit this. In addition, according to an embodiment of the present application, Figure 8 and Figure 9 In the clothes 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 through a drainage pump or stored in a water box, and this application does not impose any restrictions on this.

[0073] Figure 10 The air flow diagram of the clothes processing device in the third embodiment of the present application is shown. Figure 10 , Figure 10 The main difference between the laundry processing device shown here and the laundry processing device described above is that the refrigerant can be controlled to enter at least one of the evaporator 5 and condenser 6 of the heat pump module after passing through the throttling component 9, so that the laundry processing device can have different dehumidification modes, that is, perform at least one of heat pump dehumidification and moisture absorption dehumidification module dehumidification. For other details, please refer to the relevant description of the laundry processing device described above. Specifically, the compressor 8 has an output and an input. The output of the compressor 8, the condenser 6, and the throttling component 9 are connected in sequence. The throttling component 9 can be controllably connected to at least one of the cooler 7 and the evaporator 5. The cooler 7 and the evaporator 5 are both connected to the input of the compressor 8. The output portion of compressor 8 outputs a high-temperature, high-pressure gaseous refrigerant. After passing through condenser 6 and releasing heat, the high-temperature, high-pressure gaseous refrigerant becomes a high-pressure, medium-temperature liquid refrigerant. The high-pressure, medium-temperature liquid refrigerant is then cooled and reduced in pressure by throttling component 9 to become a low-temperature, low-pressure, gas-liquid two-phase refrigerant. The low-temperature, low-pressure gas-liquid two-phase refrigerant then enters at least one of evaporator 5 and cooler 7 to absorb heat before entering compressor 8 to be compressed into a high-temperature, high-pressure gaseous refrigerant, and the cycle repeats. For information on how the refrigerant can be controlled to enter at least one of evaporator 5 and condenser 6 after passing through throttling component 9, enabling the laundry processing apparatus to have different dehumidification modes, please refer to the relevant description of the control method below.

[0074] Combine Figure 10According to one embodiment of the present 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 throttle component 9 and the evaporator 5 to control the flow between the throttle component 9 and the evaporator 5. The second valve body 13 is disposed between the throttle component 9 and the cooler 7 to control the flow between the throttle component 9 and the cooler 7. Both the first valve body 12 and the second valve body 13 may be one-way valves to prevent refrigerant backflow.

[0075] Combine Figure 10 In one embodiment, one end of the first valve body 12 is connected between the throttle 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 configuration can save some piping for transporting the refrigerant. In another embodiment, the first valve body 12 and the second valve body 13 can also be connected to the throttle component 9 through corresponding refrigerant pipelines, which is not limited in this application.

[0076] Combine Figure 8 、 Figure 9 as well as Figure 10 In the third aspect of the present application, the present application also provides a clothing processing device, which includes a drum 3, and the drum 3 is provided with an air outlet and an air inlet. The above-mentioned drying device 4 is respectively connected to the air outlet and the air inlet of the drum 3.

In another embodiment, the second air inducing member 10 may also be disposed upstream of the evaporator 5, so that the second air inducing member 10 circulates the air between the drying device 44 and the drum 33 of the laundry processing apparatus.

[0079] Combine Figure 8 、 Figure 9 as well as Figure 10 According to one embodiment of the present application, the clothing processing device also includes a filter 11, which is arranged between the air outlet of the drum 3 and the evaporator 5 to filter the hair debris in the air flow drawn out from the drum to prevent the hair debris from being introduced into the drying device 4 and affecting the operation of the drying device 4.

[0080] The clothing processing device provided in this application can be a clothes dryer or a washer-dryer, which can reduce the moisture content of the drying airflow introduced into the drum 3, effectively improving the drying efficiency of the clothing processing device, reducing the drying time, and improving the drying efficiency of the clothing processing device, thereby having excellent practicality. As for the corresponding structure of the clothing processing device, please refer to the corresponding description above, and this application will not repeat it again.

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

[0082] In a fourth aspect of the present application, the present application also provides a control method for the clothing processing device shown in Example 3. Figure 11 A flow chart showing a control method of a clothes processing device of the present application is shown. 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 throttling component 9 is controlled to be connected to the cooler 7 and the evaporator 5, that is, the first valve body 12 and the second valve body 13 are controlled to be open, and the clothes processing device performs dehumidification by the heat pump and the moisture absorption and dehumidification module 41. The heat pump system composed of the evaporator 5 and the condenser 6 and the moisture absorption and dehumidification module 41 work simultaneously, which can effectively increase the temperature in the drum, avoid the initial temperature preheating time, 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 clothes processing equipment;

[0086] S31: When the clothes processing apparatus is in the early stage of drying, the throttling component 9 is controlled to be connected to the evaporator 5, and the throttling component 9 is disconnected from the cooler 7, that is, the first valve body 12 is controlled to be open and the second valve body 13 is controlled to be closed. The clothes processing apparatus performs heat pump dehumidification. The heat pump system with stronger dehumidification capacity can work to ensure that the temperature inside the drum rises quickly, thereby improving the drying efficiency.

[0087] S32: When the clothing processing equipment is in the late stage of drying, the throttling component 9 and the cooler 7 are controlled to be connected, and the throttling component 9 and the evaporator 5 are disconnected. The clothing processing equipment executes the dehumidification module 41 for dehumidification, that is, the first valve body 12 is controlled to be 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 becomes weak. Therefore, dehumidification is performed through the wheel of the dehumidification module 41 to ensure the internal temperature of the cylinder and the drying efficiency.

[0088] The control method of the clothing processing device provided in the present application can place the clothing processing device in different dehumidification modes by controlling the on and off of the valve body to adapt to different drum temperatures, ensure the internal temperature of the drum, and improve the drying efficiency.

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