[0041] 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.

[0042] 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.

[0043] 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 2 The 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 11 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 11. The drum 3 is rotatably mounted inside the housing 1 to accommodate clothes.

[0044] As 1 and Figure 2 As shown, in one embodiment of the present application, an air inlet 12 of an air inlet channel is disposed below the inlet port 11, an air outlet 13 is disposed below the drum 3, and an air inlet 14 is disposed on the back of the drum 3. The drum 3, the air outlet 13, and the air inlet 14 are sequentially connected to form an air duct for air circulation. A drying device 4 is disposed within the air outlet 13. The humid air discharged from the drum 3 enters the air outlet 13 from the air inlet 12 and is dried by the drying device 4 to form a clean, dry airflow. The air inlet 14 introduces the dry airflow into the drum 3 to dry the clothes inside.

[0045] It should be noted that Figure 1 and Figure 2 The layout of a drying device 4, an air outlet duct 13 and its air inlet 12, and an air inlet duct 14 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 airflow flowing out of the drum 3 into a dry airflow. Accordingly, the air outlet duct 13 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, so they are not listed one by one.

[0046] In related art, the drying device of heat pump drying mode clothing processing equipment includes a heat pump module and an induced draft fan. The heat pump module includes an evaporator and a condenser arranged along the airflow direction. Under the action of the induced draft fan, the moist air in the drum flows to 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 has a technical problem of long drying time, resulting in room for improvement in the drying efficiency of clothing processing equipment.

[0047] 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.

[0048] 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.

[0049] 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 the moisture in the high-temperature airflow, 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.

[0050] The specific technical solutions will be described in detail with reference to the drawings that are not necessarily drawn to scale. Similar or same reference numerals can be used to designate similar or same parts in different drawings. The use of similar or same reference numerals in different drawings does not mean that all drawings including the similar or same reference numerals constitute a single or same embodiment. The drawings generally illustrate various embodiments discussed in the present application in an exemplary and non-limiting manner.

[0051] Based on the above design idea, in a first aspect of the present application, the present application provides a moisture adsorption and removal module, which is part of a drying device. Figure 3 A structural schematic diagram of a moisture adsorption and removal module in one or more embodiments of the present application is shown, Figure 4 A structural schematic diagram of another view of Figure 3 is shown. In combination with Figure 3 and Figure 4 , the moisture adsorption and removal module includes a regeneration housing 411 and a wheel disc 412. Figure 5 A structural schematic diagram of the regeneration housing 411 in Figure 3 is shown, Figure 6 A structural schematic diagram of another view of Figure 5 is shown, in combination with Figure 5 and Figure 6 , the regeneration housing 411 is provided with a containing cavity 4111, the containing cavity 4111 is provided with a moisture removal zone 4112 and a desorption zone 4113 at intervals, and the wheel disc 412 is rotatably arranged in the containing cavity 4111. When the wheel disc 412 rotates to the moisture removal zone 4112, the wheel disc 412 adsorbs the moisture in the moisture flow. When the wheel disc 412 rotates to the desorption zone 4113, the moisture adsorbed by the wheel disc 412 is separated out under the action of the heating assembly 44.

[0052] When the moisture adsorption and removal module provided by the present application is applied to a drying device, the moisture flow introduced from the air outlet of the cylinder 3 of the drying device is separated out by the evaporator 5, and then adsorbed onto the wheel disc 412 of the moisture adsorption and removal module. When the wheel disc 412 rotates to the moisture removal zone 4112, the wheel disc 412 further separates out the moisture in the moisture flow, forming a low-temperature dry gas flow. The low-temperature dry gas flow is heated by the condenser 6, and then generates a high-temperature dry gas flow to dry the clothes. Since the moisture is adsorbed by the wheel disc 412 in the moisture removal zone 4112, the moisture in the dry gas flow is reduced, and the drying efficiency of the clothes treatment device is effectively improved, and the drying time is reduced. When the wheel disc 412 rotates to the desorption zone 4113, the moisture adsorbed by the wheel disc 412 is separated out under the action of the heating assembly 44, to generate a moisture flow. The moisture flow is again adsorbed by the evaporator 5 and the wheel disc 412, and heated by the condenser 6, to generate a high-temperature dry gas flow for reuse, thereby improving the drying efficiency of the clothes treatment device. The specific details of the moisture adsorption and removal module are further described by means of the drawings.

[0053] 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.

[0054] Combine Figure 5 as well as Figure 6 According 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.

[0055] 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.

[0056] 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.

[0057] Figure 7 Shown Figure 2 Schematic diagram of the structure of the heating component 44. Figure 7According 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.

[0058] 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.

[0059] 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 FIG1 shows an airflow diagram of the drying device 4 in one or more embodiments of the present application. Figure 8The drying device 4 includes a heat pump module, the aforementioned moisture absorption and dehumidification module, and a heating assembly. The heat pump module includes an evaporator 5 and a condenser 6. In one embodiment, the evaporator 5, the dehumidification zone 4112 of the moisture absorption and dehumidification module, and the condenser 6 are sequentially connected, while the heating assembly, the desorption zone 4113 of the moisture absorption and dehumidification module, and the evaporator 5 are sequentially connected. 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 portion 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 is adsorbed by the dehumidification zone 4112 of the wheel 412, the moisture content of 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 to dry clothes, thereby avoiding energy waste in the air flow, improving the utilization rate of the energy in the air flow, and improving the drying efficiency of the clothing processing equipment.

[0060] Combine Figure 8 In one embodiment, the evaporator 5 is provided with an independent first evaporation channel 51 and a second evaporation channel 52. The first evaporation channel 51 is a main airflow channel connected to the condenser 6, and the second evaporation channel 52 is an auxiliary airflow channel connected to the desorption zone 4113 of the moisture absorption and dehumidification module 41. That is, the two independent evaporation channels of the evaporator 5 are used to respectively realize water separation of two airflows. Among them, the first evaporation channel 51 of the evaporator 5 realizes water separation of the main airflow released from the air outlet portion of the cylinder 3, and the second evaporation channel 52 of the evaporator 5 realizes water separation of the auxiliary airflow released from the desorption zone 4113 of the moisture absorption and dehumidification module 41. Such a configuration can prevent airflow turbulence in the evaporator 5 through the two independent evaporation channels of the evaporator 5, allowing the airflow to flow in a predetermined direction, and thus achieving higher water separation efficiency.

[0061] Figure 9 Shows another airflow schematic diagram of the drying device 4, combined with Figure 9In another embodiment, the evaporator 5, the condenser 6 and the dehumidification zone 4112 of the moisture absorption and dehumidification module 41 are connected in sequence, that is, the dehumidification zone 4112 of the moisture absorption and dehumidification module 41 is arranged downstream of the condenser 6, the heating component 44, the desorption zone 4113 of the moisture absorption and dehumidification module 41 and the evaporator 5 are connected in sequence. When the moisture absorption and dehumidification module provided by the present application is applied to the drying equipment, the humid air flow drawn out from the air outlet of the cylinder 3 of the drying equipment passes through the evaporator 5 to precipitate a part of the water, forming a low-temperature air flow. After the low-temperature air flow exchanges heat with the condenser 6, a high-temperature air flow is generated. The high-temperature air flow is adsorbed on the wheel 412 of the moisture absorption and dehumidification module, and the wheel 412 rotates to the dehumidification zone 4112. When the wheel 412 rotates to the desorption zone, the moisture adsorbed by the wheel 412 is precipitated under the action of the heating component 44 to generate a wet air flow. The wet air flow is again absorbed by the evaporator 5, heated by the condenser 6 and adsorbed by the wheel 412 to generate a high-temperature dry air flow to dry the clothes, so as to avoid energy waste in the air flow, improve the energy utilization rate in the air flow and improve the drying efficiency of the clothes processing equipment.

[0062] Combine Figure 8 as well as Figure 9 According to one embodiment of the present application, the drying device 4 further includes a second air inducing member 7, which is disposed downstream of the condenser 6 in the airflow direction. In another embodiment, the second air inducing member 7 is disposed upstream of the evaporator 5. The second air inducing member 7 circulates air between the drying device 4 and the drum 3 of the laundry processing apparatus.

[0063] Combine Figure 8 as well as Figure 9 According to one embodiment of the present application, the drying device 4 also includes a compressor 8 and a throttling device 9. The compressor 8 and the throttling device 9 are connected in parallel between the evaporator 5 and the condenser 8 to realize the circulation flow of the refrigerant. This is the existing technology and will not be elaborated again.

[0064] The drying device 4 having the above-mentioned moisture absorption and dehumidification module can reduce the moisture content of the drying airflow, effectively improve the drying efficiency of the clothing processing equipment, and reduce the drying time; and avoid energy waste in the airflow, improve the utilization rate of the energy in the airflow, and improve the drying efficiency of the clothing processing equipment, and has good practicality.
