The embodiments disclosed herein are not necessarily limited to the contents of this document.

[0032] The use of "adapted to" or "configured to" herein is intended to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.

[0033] As used herein, "about," "substantially," or "approximately" includes the stated value and an average value that is within an acceptable range of deviation from the particular value as determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0034] As used herein, "parallel", "perpendicular", and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within an acceptable deviation range, wherein the acceptable deviation range is as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the specific quantity (i.e., the limitations of the measurement system).

[0035] In the related art, clothing processing equipment, such as a washer-dryer, generally includes a housing, a drum, and a drying duct. The drum is located inside the housing. The drum includes an inner cavity. The drying duct is formed in the gap between the housing and the drum. The inner cavity is connected to the drying duct. In this way, air circulation can be achieved, and a dry hot air flow is introduced into the drum, and then the hot air flow carrying water vapor is guided out of the drum, so that the clothing processing equipment can achieve the function of drying clothes. The clothing processing equipment is generally also provided with a fan assembly, which is located in the drying duct and is used to compress and transport gas to form an air flow, thereby achieving air circulation.

[0036] However, due to the size of the cabinet of the clothes processing device, it is difficult to arrange the drying duct reasonably, resulting in increased wind resistance of the fan assembly and reduced air volume, thereby reducing the drying efficiency of the clothes processing device.

[0037] In response to the above technical problems, some embodiments of the present disclosure provide a clothing processing device 1. As shown in Figures 1 to 7, the clothing processing device 1 includes: a housing 10, a drum 20 and a drying device 30. The housing 10 includes a accommodating cavity 100. The drum 20 is rotatably disposed in the accommodating cavity 100, and a side surface of the housing 10 close to the drum 20 is spaced apart from the drum 20 to form an installation space; the drum 20 includes an inner cavity 200. The drying device 30 is located in the installation space, and the drying device 30 includes: a shell 31, an evaporator 32, a condenser 33 and a fan assembly 34.

[0038] A side wall of the housing 31, located near the drum 20, extends generally along the circumference of the drum 20. The housing 31 includes a first air duct 310 (e.g., a drying air duct) and a base 311. The first air duct 310 has a first air duct inlet 310A and a first air duct outlet 310B. The base 311 is located on the side of the housing 31 near the drum 20. The base 311 includes a horizontal portion 3110 and an inclined portion 3111 connected to each other. The horizontal portion 3110 and the inclined portion 3111 are arranged sequentially along the direction of airflow within the first air duct 310. The cross-sectional area of ​​the first air duct 310 increases from the first air duct inlet 310A to the first air duct outlet 310B (referring to the left-right direction in FIG. 5 ). The evaporator 32 is disposed in the first air duct 310, corresponding to the horizontal portion 3110. The condenser 33 is disposed in the first air duct 310, corresponding to the inclined portion 3111.

[0039] The fan assembly 34 has an air inlet 34A and an air outlet 34B; the air inlet 34A is connected to the first air duct outlet 310B; and the air outlet 34B is connected to the inner cavity 200 .

[0040] The clothes drying principle of the clothes treating apparatus 1 will be described below.

[0041] In some embodiments, the drying device 30 is configured as follows: air is heated by the condenser 33 to generate dry hot air; the dry hot air is then input into the inner cavity 200 of the drum 20 through the fan assembly 34, where it exchanges heat with the damp clothes in the drum 20, evaporating the moisture in the clothes and generating humid hot air; the humid hot air then enters the first air duct 310 through the first air duct inlet 310A, flows sequentially through the evaporator 32 and the condenser 33, and then returns to the inner cavity 200 of the drum 20. This achieves air circulation and drying of the clothes in the inner cavity 200 of the drum 20.

[0042] In some embodiments, a side wall of the housing 31 adjacent to the drum 20 extends substantially along the circumference of the drum 20, such that the main body of the drying device 30 is located within the circumferential installation space of the drum 20, fully utilizing the circumferential installation space of the drum 20 of the laundry processing apparatus 1. For example, as shown in Figures 1, 4, and 5, the main body of the drying device 30 is located in the upper region of the drum 20.

[0043] In some embodiments, the base 311 is located on a side of the housing 31 near the drum 20. The base 311 includes a horizontal portion 3110 and an inclined portion 3111 connected to each other. The cross-sectional area of ​​the first air duct 310 increases from the first air duct inlet 310A to the first air duct outlet 310B. Thus, compared to a case where the cross-sectional area of ​​the first air duct 310 remains unchanged from the first air duct inlet 310A to the first air duct outlet 310B, the cross-sectional area of ​​the air duct between the condenser 33 and the fan assembly 34 is increased, and the cross-sectional area of ​​the air duct before the airflow enters the air inlet 34A of the fan assembly 34 is increased. This reduces the flow rate of the airflow at the air inlet 34A of the fan assembly 34, reduces the wind resistance of the fan assembly 34, increases the air volume, improves the operating efficiency of the fan assembly 34, and thereby improves the drying efficiency of the laundry processing device 1.

[0044] In addition, the horizontal portion 3110 and the inclined portion 3111 are arranged in sequence along the flow direction of the airflow in the first air duct 310; thus, the side of the shell 31 of the drying device 30 close to the drum 20 can match the circumferential shape of the drum 20, making full use of the circumferential installation space of the drum 20, increasing the usable space of the first air duct 310, and thus creating conditions for the cross-sectional area of ​​the first air duct 310 to increase along the flow direction of the airflow.

[0045] In some embodiments, the clothing processing apparatus 1 includes but is not limited to a drum washer-dryer and a clothes dryer with a drum.

[0046] In some embodiments, as shown in FIG7 , a housing 10 serves as the outer shell of the laundry processing apparatus 1. The housing 10 is a generally rectangular hollow structure. The interior space of the housing 10 can provide installation space for the drum 20 and the drying device 30.

[0047] In some embodiments, the laundry processing apparatus 1 further includes a door. The housing 10 further includes a laundry inlet. The door is configured to open or close the laundry inlet. For example, the door is hinged to a side of the housing 10 near the laundry inlet. Thus, the door can rotate to open and close the door, thereby opening and closing the laundry inlet.

[0048] In some embodiments, as shown in Figures 7 and 8, the drum 20 has a drum opening 201. The drum opening 201 is directly opposite the clothing loading port. Thus, after the door is opened, clothes can be sequentially placed into the inner cavity 200 through the clothing loading port and the drum opening, and then washed and dried by the clothes processing apparatus 1.

[0049] In some embodiments, the drum 20 is rotatably disposed in the accommodating cavity 100. Thus, during the drying process, the drum 20 can drive the clothes in the inner cavity to rotate, so that the clothes are fully exposed to the air flow, thereby improving the drying efficiency and uniformity of the clothes processing device 1.

[0050] In some embodiments, as shown in Figures 8 and 9, the drum 20 includes an outer drum 202 and an inner drum 203. The outer drum 202 is fixedly mounted inside the housing 10. The inner drum 203 is rotatably disposed within the inner cavity of the outer drum 202. The inner cavity of the inner drum 203 serves as the inner cavity 200 of the drum 20. The inner cavity 200 is configured as a washing chamber for holding laundry to be washed or dried. Thus, the inner drum 203 can drive the laundry to rotate relative to the outer drum 202, thereby cleaning or drying the laundry in the inner cavity 200.

[0051] In some embodiments, the outer tub 202 is configured to contain washing liquid, that is, the inner space of the outer tub 202 is used to hold washing liquid. For example, the washing liquid is a mixture of water, detergent, softener, etc.

[0052] In some embodiments, as shown in Figures 8 and 9, the outer cylinder 202 and the inner cylinder 203 are coaxially arranged. The outer cylinder 202 and the inner cylinder 203 each have an opening, and the openings of the outer cylinder 202 and the inner cylinder 203 are combined to form the cylinder opening 201 of the drum 20.

[0053] In some embodiments, the laundry processing apparatus 1 further comprises a driving device. The driving device is located outside the drum 20. An output end of the driving device is in transmission connection with the drum 20. Thus, the driving device can drive the drum 20 to rotate.

[0054] In some embodiments, the output end of the driving device extends into the interior of the outer cylinder 202 and is in transmission connection with the inner cylinder 203. Thus, the driving device can drive the inner cylinder to rotate relative to the outer cylinder.

[0055] In some embodiments, as shown in Figures 7 to 9 , the drum 20 has a second air inlet 20A and an air outlet 20B on opposite sides thereof. Thus, air can enter the inner cavity 200 of the drum 20 through the second air inlet 20A, interacting with the clothes in the inner cavity 200; the air can remove moisture from the clothes, generating humid and hot air; and the humid and hot air can be discharged out of the drum 20 through the air outlet 20B.

[0056] For example, as shown in FIG7 to FIG9, the second air inlet 20A is located at the front end of the drum 20, and the exhaust port 20B is located at the rear end of the drum 20; the second air inlet 20A and the exhaust port 20B are respectively connected to the inner cavity 200 of the drum 20.

[0057] In some embodiments, the second air inlet 20A may be located at the rear end of the drum 20 , and the air outlet 20B may be located at the front end of the drum 20 .

[0058] In some embodiments, the clothing loading port is connected to the inner cavity 200 and the air outlet 34B respectively. The exhaust port 20B is arranged opposite to the clothing loading port; the exhaust port 20B is connected to the inner cavity 200 and the first air duct inlet 310A respectively.

[0059] For example, as shown in FIG1 , the laundry loading port and the air outlet 34B are located at the front end of the drum 20 , and the air outlet 20B is located at the rear end of the drum 20 .

[0060] In some embodiments, as shown in Figures 4 and 5, the evaporator 32 and the condenser 33 are arranged in the first air duct 310 corresponding to the horizontal portion 3110 and the inclined portion 3111, respectively. The horizontal portion 3110 and the inclined portion 3111 are arranged in sequence along the flow direction of the airflow in the first air duct 310. Thus, the evaporator 32 and the condenser 33 are arranged in sequence along the flow direction of the airflow in the first air duct 310. In the first air duct 310, the hot and humid air flow passes through the evaporator 32 to cool down and condense to remove moisture from the hot and humid air flow, thereby obtaining a dry air flow; the dry air flow is heated by the condenser 33 to obtain a dry hot air flow. The dry hot air flow can be used to dry the clothes in the drum 20.

[0061] In some embodiments, as shown in Figures 4 and 5 , the surface of condenser 33 corresponding to inclined portion 3111 is an inclined surface 33C, which matches inclined portion 3111. Thus, on the one hand, inclined surface 33C and inclined portion 3111 are inclined in the same direction, facilitating assembly of condenser 33; on the other hand, the heat exchange area of ​​condenser 33 is increased, improving the heat exchange capacity of condenser 33 and thereby enhancing the drying efficiency of laundry processing apparatus 1.

[0062] In some embodiments, the evaporator 32 and the condenser 33 are arranged side by side, thereby making full use of the space in the first air duct 310 and facilitating reduction in the volume of the laundry processing apparatus 1 .

[0063] In some embodiments, the airflow from the first air duct 310 to the air inlet 34A of the fan assembly 34 flows in substantially the same direction. For example, referring to FIG5 , the airflow from the first air duct outlet 310B, the air inlet 34A, and the airflow within the first air duct 310 all flow toward the same side (the right side) of the drum 20. This reduces resistance losses before the fan assembly 34, reduces energy loss during airflow within the duct, increases the air volume of the fan assembly 34, improves the operating efficiency of the fan assembly 34, and thereby enhances the drying efficiency of the laundry processing apparatus 1. It also helps extend the service life of the fan assembly 34.

[0064] In some embodiments, the fan assembly 34 is located at the first air duct outlet 310B. For example, the first air duct outlet 310B is directly connected to the air inlet 34A. As a result, the airflow through the first air duct 310 can be directly output to the air inlet 34A of the fan assembly 34 without changing the flow direction of the airflow, thereby reducing air volume loss.

[0065] In some embodiments, as shown in Figures 1 and 3 to 5, the fan assembly 34 includes a fan 340 and a fan housing 341. The fan 340 is used to provide wind force so that the airflow flowing through the first air duct 310 can enter the inner cavity 200 of the drum 20 through the fan 340. The fan housing 341 is formed with an air inlet 34A and an air outlet 34B. The fan housing 341 is configured to install the fan 340. The fan housing 341 can be in the shape of a volute to adjust the flow direction of the airflow flowing out of the air outlet 34B. Referring to Figure 1, the fan housing 341 in the shape of a volute can guide the airflow from the upper right side of the drum 20 to the upper front end of the drum 20.

[0066] In some embodiments, as shown in FIG. 8 and FIG. 9 , the fan assembly 34 and the housing 31 are arranged along the circumference of the drum 20 , and the fan 340 faces the central axis of the drum 20 .

[0067] For example, the housing 31 and the fan assembly 34 are located above the drum 20. For example, referring to Figure 5, the fan assembly 34 is located on the right side of the housing 31. In some embodiments, the fan assembly 34 may also be located on the left side of the housing 31, which is not limited in this disclosure.

[0068] In some embodiments, the condenser 33 includes a condenser body and condenser fins; the condenser fins are located on the surface of the condenser body; and the end of the condenser fin facing the drum 20 is inclined toward the drum 20 to form an inclined surface 33C.

[0069] In some embodiments, as shown in Figures 2 and 5, the housing 31 further includes a stopper assembly 312; the stopper assembly 312 is located between the condenser 33 and the inclined portion 3111 to fix the position of the condenser 33 relative to the inclined portion 3111. This prevents the condenser 33 from sliding or falling out relative to the housing 31, thereby improving the installation stability and reliability of the condenser 33.

[0070] In some embodiments, as shown in FIG6 , the retaining assembly 312 includes a retaining rib 3120 and a retaining groove 3121. The retaining rib 3120 is located on one of the condenser 33 and the inclined portion 3111. The retaining groove 3121 is located on the other of the condenser 33 and the inclined portion 3111. The retaining groove 3121 matches the retaining rib 3120 so that the retaining rib 3120 engages with the retaining groove 3121. The retaining assembly 312 includes one or more sets of retaining ribs 3120 and retaining grooves 3121.

[0071] For example, Figures 2 and 5 show an example in which the limiting rib 3120 is located on the inclined portion 3111, the limiting groove 3121 is located on the condenser 33, and the limiting assembly 312 includes multiple groups of limiting ribs 3120 and limiting grooves 3121. Of course, the present disclosure is not limited to this.

[0072] In some embodiments, the retaining assembly 312 includes a plurality of retaining ribs 3120 and a plurality of retaining grooves 3121. A portion of the retaining ribs 3120 is located on the condenser 33, while another portion is located on the inclined portion 3111. A portion of the retaining grooves 3121 is located on the condenser 33, while another portion is located on the inclined portion 3111. Thus, the condenser 33 and the inclined portion 3111 are both provided with retaining ribs 3120 and retaining grooves 3121, which can also improve the installation stability and reliability of the condenser 33.

[0073] In some embodiments, the position limiting assembly 312 includes a position limiting block located at an end of the inclined portion 3111 away from the horizontal portion 3110 (e.g., the right end of the horizontal portion in FIG. 5 ). The position limiting block abuts against the inclined portion 3111 and the condenser 33 to secure the position of the condenser 33 relative to the inclined portion 3111.

[0074] In some embodiments, as shown in Figures 1, 2, and 5, the housing 31 further includes a cover 313. The cover 313 is detachably mounted on a side of the base 311 away from the drum 20 to define a first air duct 310 between the base 311 and the cover 313. For example, the cover 313 and the base 311 may be connected by screws or a snap-fit ​​structure.

[0075] In some embodiments, the side surface of the housing 31 facing away from the drum 20 (e.g., the upper surface) is horizontal; the side surface of the housing 31 facing toward the drum 20 (e.g., the lower surface) matches the shape of the drum 20, and the housing 31 is spaced apart from the drum 20. The evaporator 32, condenser 33, and fan assembly 34 are secured by the housing 31 so that the sides of the evaporator 32, condenser 33, and fan assembly 34 facing away from the drum 20 are substantially on the same horizontal plane. This improves the flatness of the side of the drying device 30 facing away from the drum 20, helps reduce the height of the laundry processing apparatus 1, and saves space in the laundry processing apparatus 1.

[0076] In some embodiments, as shown in FIG4 and FIG5 , the cover 313 is a flat plate, and the horizontal portion 3110 corresponding to the evaporator 32 is parallel to the cover 313 .

[0077] In some embodiments, as shown in FIG. 4 and FIG. 5 , the inclined portion 3111 corresponding to the condenser 33 includes but is not limited to a straight plate, an arc-shaped plate or a bent plate that matches the circumferential shape of the drum 20 , and the like.

[0078] In some embodiments, as shown in Figures 2 and 5, the first air duct 310 includes a connected air duct body 3100 and a first guide air duct 3101; the first guide air duct 3101 is located at one end of the air duct body 3100 close to the air inlet 34A to guide the air flow passing through the condenser 33 into the air inlet 34A.

[0079] For example, as shown in Figures 2 and 5 , because condenser 33 is positioned relative to inclined portion 3111, the cross-sectional area of ​​first air duct 310 increases from first air duct inlet 310A to first air duct outlet 310B, and first guide air duct 3101 is located at the end of air duct body 3100 near air inlet 34A. This reduces wind resistance and increases the air volume of fan assembly 34, thereby improving the drying efficiency of clothes processing apparatus 1.

[0080] In some embodiments, as shown in Figures 4 and 5, the clothing processing apparatus 1 further includes a filter assembly 40 (e.g., a filter); the filter assembly 40 is located in the first air duct 310, and the filter assembly 40, evaporator 32, condenser 33, and fan assembly 34 are arranged sequentially along the flow direction of the airflow within the first air duct 310. Thus, after the filter assembly 40 removes impurities such as lint and fine particles from the airflow, the airflow is condensed and dehumidified by the evaporator 32, heated by the condenser 33, and then returned to the inner cavity 200, forming an air circulation system. The filter assembly 40 filters the airflow flowing through the first air duct 310, improving the cleanliness of the airflow. This prevents impurities in the airflow from contaminating the clothes during the drying process, thereby improving the cleanliness of the clothes after being treated by the clothing processing apparatus 1. The filter assembly 40 also prevents impurities such as lint and fine particles from the clothes from reaching the surface of the evaporator 32 with the airflow, which could reduce the operating efficiency of the evaporator 32, thereby improving the drying efficiency of the clothing processing apparatus 1.

[0081] In some embodiments, as shown in FIG5 , the drying device 30 further includes a bellows 35 . One end of the bellows 35 is connected to the exhaust port 20B, and the other end is connected to the first air duct inlet 310A. Thus, air can flow from the inner cavity 200 of the drum 20 through the bellows 35 into the first air duct 310 . The bellows 35 can also act as a shock absorber.

[0082] In some embodiments, a laundry processing device is provided, as shown in Figures 7 to 20 . This device differs from the aforementioned laundry processing devices in that the first air duct 310 includes a connected air duct body 3100 and a second air guide duct 3103 (see Figures 12 and 13 ). The second air guide duct 3103 is located at one end of the air duct body 3100 near the first air duct inlet 310A. The inner cavity 200 is connected to the second air guide duct 3103. The base 311 includes a connected first mounting cavity 3112 and a second mounting cavity 3113. The first and second mounting cavities 3112 and 3113 are located within the air duct body 3100 and arranged sequentially in the direction of airflow within the first air duct 310. The evaporator 32 is disposed in the first mounting cavity 3112, and the condenser 33 is disposed in the second mounting cavity 3113. The second air guide duct 3103, the filter assembly 40, and the evaporator 32 are arranged sequentially in the direction of airflow within the first air duct 310. Thus, airflow passing through the inner cavity 200 is guided into the filter assembly 40 via the second air guide duct 3103, filtered by the filter assembly 40, enters the first mounting cavity 3112, undergoes contact condensation on the evaporator 32, then enters the second mounting cavity 3113, is heated by the condenser 33, and then returns to the inner cavity 200, forming an airflow cycle. This helps improve the flow efficiency of the airflow, thereby enhancing the drying efficiency of the drying device 30.

[0083] It should be noted that the first installation cavity 3112 may correspond to the horizontal portion 3110 , and the second installation cavity 3113 may correspond to the inclined portion 3111 .

[0084] In some embodiments, as shown in Figures 8 to 16 , the base 311 is located above the top of the drum 20. The evaporator 32 and the condenser 33 are respectively disposed in a first installation cavity 3112 and a second installation cavity 3113 of the base. This fully utilizes the installation space in the upper area of ​​the housing 10, which helps reduce the size of the laundry processing apparatus 1.

[0085] In some embodiments, as shown in FIG. 11 to FIG. 16 , the first installation cavity 3112 has a first air inlet 3112A; the first air inlet 3112A and the condenser 33 are respectively located on opposite sides of the first installation cavity 3112; and the filter assembly 40 is located at the first air inlet 3112A.

[0086] As shown in Figures 17 to 19, the filter assembly 40 includes a filter screen 400 and a filter box 401. The filter screen 400 matches the first air inlet 3112A, so that the airflow flowing through the second guide air duct 3103 is filtered by the filter screen 400 and then enters the first installation cavity 3112 through the first air inlet 3112A. The filter box 401 matches the filter screen 400, and the filter screen 400 is located in the filter box 401. This facilitates the use of the filter box 401 to secure the filter screen 400 to the first air inlet 3112A. The second guide air duct 3103, the filter box 401, and the evaporator 32 are arranged in sequence along the flow direction of the airflow in the first air duct 310.

[0087] In some embodiments, as shown in FIG. 8 to FIG. 13 , the filter assembly 40 is mounted on a base 311 .

[0088] In some embodiments, the first air inlet 3112A, the filter box 401 and the filter screen 400 are in the shape of an elongated strip. The length directions of the first air inlet 3112A, the filter box 401 and the filter screen 400 are consistent.

[0089] In some embodiments, as shown in Figures 17 to 19, the filter box 401 has a first opening 401A and a second opening 401B; the first opening 401A and the second opening 401B are opposite and connected; the first opening 401A is connected to the second air guide duct 3103; the second opening 401B is connected to the first air inlet 3112A; the filter net 400 is located at at least one of the first opening 401A or the second opening 401B.

[0090] For example, the first opening 401A is opposite to and communicates with the second air guide duct 3103 ; the second opening 401B is opposite to and communicates with the first air inlet 3112A.

[0091] In some embodiments, the filter assembly 40 includes: a plurality of filter screens 400 , and the plurality of filter screens 400 are arranged side by side inside the filter box 401 .

[0092] 8 to 13 , the filter cartridge 401 is detachably connected to the housing 31, and one end of the filter cartridge 401 is located outside the housing 31. For example, the filter cartridge 401 is retractably connected to the housing 31.

[0093] In some embodiments, as shown in FIG7 , the filter cartridge 401 is retractably connected to the housing 31 along its length, with one end of the filter cartridge 401 located outside the housing 10. Thus, the filter cartridge 401 is retractably connected to the base 311 along its length. Through the end of the filter cartridge 401 exposed to the housing 10, the filter cartridge 401 can be withdrawn from the base 311 along its length to facilitate cleaning or replacement of the filter cartridge 401 or the filter screen 400. After replacing the filter cartridge 401 or the filter screen 400, the filter cartridge 401 can be reinserted into the base 311 through the end of the filter cartridge 401 exposed to the housing 10.

[0094] In some embodiments, the exposed end of the filter box 401 can also be covered inside the box body 10 by a cover plate. After opening the cover plate, the filter box 401 can be fully or partially pulled out of the box body 10.

[0095] In some embodiments, the cross-sectional area of ​​the second air guiding duct 3103 increases along the flow direction of the airflow in the second air guiding duct 3103 , thereby allowing the airflow to diffuse in the second air guiding duct 3103 .

[0096] In some embodiments, the inlet end of the second air guide duct 3103 is elongated and matches the first air inlet 3112A. The inlet end of the second air guide duct 3103 is opposite and connected to the first air inlet 3112A. The first air inlet 3112A is opposite the evaporator 32. As a result, the second air guide duct 3103 can increase the heat exchange area between the moist hot air flow and the evaporator 32, thereby improving the condensation efficiency of the evaporator 32 and, in turn, the drying efficiency of the clothing processing device 1.

[0097] In some embodiments, as shown in Figures 11 to 20, the laundry processing apparatus 1 further includes a cleaning assembly 50; the cleaning assembly 50 includes a cleaning line 500; the cleaning line 500 has a cleaning port 500B; the cleaning port 500B is disposed opposite the evaporator 32 so that cleaning liquid flowing through the cleaning line 500 can be sprayed onto the surface of the evaporator 32 through the cleaning port 500B to clean the surface of the evaporator 32. The first mounting cavity 3112 includes a condensation groove 31120, which is located at the bottom of the evaporator 32; the condensation groove 31120 has a drain port 31120B; the drain port 31120B extends through the housing 31 to drain liquid flowing through the condensation groove 31120.

[0098] Thus, on the one hand, the cleaning liquid in the cleaning pipeline 500 can be sprayed onto the surface of the evaporator 32 through the cleaning port 500B, and impurities such as lint on the surface of the evaporator 32 flow into the condensation tank 31120 along with the cleaning liquid, and are discharged to the outside of the base 311 through the drain port 31120B of the condensation tank 31120. On the other hand, when the air flow passes through the first air inlet 3112A and is condensed by the evaporator 32, the moisture carried in the air flow can condense on the surface of the evaporator 32 to obtain condensed water. The condensed water can drip into the condensation tank 31120 below the evaporator 32 under the action of gravity. The condensed water can also be collected by the condensation tank 31120. The condensed water can also be discharged to the outside of the base 311 through the drain port 31120B of the condensation tank 31120.

[0099] In some embodiments, as shown in FIG. 12 , FIG. 16 , and FIG. 20 , the cleaning line 500 is disposed along the length direction of the first air inlet 3112A, and the cleaning line 500 is located above the first air inlet 3112A.

[0100] In some embodiments, a preset gap is provided between the evaporator 32 and the condensation groove 31120. For example, as shown in Figures 13 to 16 , the housing 31 further includes a rib 314; the rib 314 is located at the bottom of the condensation groove 31120; the rib 314 is configured to support the evaporator 32 so that a preset gap is provided between the evaporator 32 and the condensation groove 31120.

[0101] In some embodiments, the housing 31 includes a plurality of ribs 314, which are spaced apart with gaps between adjacent ribs 314. Thus, when condensed water on the surface of the evaporator 32 drips onto the condensation groove 31120, the condensed water can flow along the gaps toward the drain port 31120B.

[0102] For example, the rib 314 is in the shape of an elongated strip, and the length direction of the rib 314 is consistent with the length direction of the condensation groove 31120 .

[0103] In some embodiments, the length direction of the cleaning pipeline 500 is parallel to the length direction of the evaporator 32; the cleaning pipeline 500 has a plurality of cleaning ports 500B; the plurality of cleaning ports 500B are arranged opposite to the evaporator 32, and the plurality of cleaning ports 500B are arranged at intervals.

[0104] For example, the plurality of cleaning ports 500B are oriented toward different areas of the evaporator 32 , thereby increasing the cleaning area of ​​the evaporator 32 , improving the cleaning efficiency, and contributing to improving the condensation efficiency of the evaporator 32 .

[0105] In some embodiments, as shown in Figures 13 to 15, the condensation groove 31120 includes a guide surface 31120C; the guide surface 31120C is located at the bottom of the condensation groove 31120 and is close to the drain port 31120B. The guide surface 31120C is configured to be inclined toward the drain port 31120B, and the drain port 31120B is located at the lowest point of the condensation groove 31120, so as to guide the liquid flowing through the condensation groove 31120 into the drain port 31120B through the guide surface 31120C.

[0106] In some embodiments, as shown in Figures 8 and 12, the cleaning assembly 50 further includes a drain pipe 503. The drum 20 includes a drain port 204. One end of the drain pipe 503 communicates with the drain port 31120B, and the other end of the drain pipe 503 communicates with the drain port 204. Thus, liquid from the condensation tank 31120 can be discharged from the laundry processing apparatus 1 through the drain port 31120B, the drain pipe 503, and the drain port 204, without the need for an additional water pump.

[0107] In some embodiments, one end of the drain pipe 503 may be connected to the drain port 31120B, and the other end of the drain pipe 503 may be directly connected to the outside of the box body 10 .

[0108] In some embodiments, as shown in Figures 9 to 12, the cleaning assembly 50 further includes: a water inlet pipe 501 and a water inlet valve 502. The water inlet pipe 501 connects the water inlet valve 502 and the cleaning pipeline 500. The water inlet valve 502 is connected to an external water source, and the water inlet valve 502 can control the connection or disconnection of the cleaning port 500B of the cleaning pipeline 500. Therefore, when the water inlet valve 502 is opened, the external water source can supply water to the cleaning pipeline 500 through the water inlet pipe 501; so that the cleaning liquid flowing through the cleaning pipeline 500 can be sprayed onto the surface of the evaporator 32 through the cleaning port 500B to clean the evaporator 32. When the water inlet valve 502 is closed, the water inlet pipe 501 stops supplying water to the cleaning pipeline 500.

[0109] In some embodiments, as shown in Figures 11 and 12 , the drying device 30 further includes a filter dryer 36 and a flow restrictor 37. The condenser 33, filter dryer 36, flow restrictor 37, and evaporator 32 are sequentially connected. A drain port 31120B is located at one end of the condensation tank 31120. The filter dryer 36 and flow restrictor 37 are located within the first mounting cavity 3112, above the guide surface 31120C and the drain port 31120B. Consequently, the filter dryer 36 and flow restrictor 37 are located between the outlet of the condenser 33 and the inlet of the evaporator 32, thereby improving the space utilization efficiency of the first mounting cavity 3112.

[0110] For example, the outlet of condenser 33 is connected to one end of filter drier 36 via a pipeline. The other end of filter drier 36 is connected to one end of throttle 37. The other end of throttle 37 is connected to the inlet of evaporator 32. Thus, the refrigerant in condenser 33 is dried and filtered by filter drier 36, throttled and depressurized by throttle 37, and then enters evaporator 32 to evaporate and absorb heat, thereby achieving condensation and dehumidification of the airflow by evaporator 32.

[0111] In some embodiments, the condenser 33 and the evaporator 32 are arranged side by side. The outlet of the evaporator 32 is arranged close to the inlet of the condenser 33. As a result, the drying filter 36 and the throttle 37 can be compactly arranged between the outlet of the evaporator 32 and the inlet of the condenser 33.

[0112] In some embodiments, as shown in Figures 7 to 9, the drying device 30 further includes a compressor 38, a first connecting pipe 39A, and a second connecting pipe 39B. The compressor 38 and the housing 31 are arranged along the circumference of the drum 20. The ends of the first connecting pipe 39A respectively connect the outlet of the compressor 38 and the condenser 33. The ends of the second connecting pipe 39B respectively connect the evaporator 32 and the inlet of the compressor 38. Thus, the outlet 38B of the compressor 38 is connected to the inlet of the condenser 33, the outlet of the condenser 33 is connected to the inlet of the evaporator 32, and the outlet of the evaporator 32 is connected to the inlet 38A of the compressor 38. This creates a circulation channel for the flow of refrigerant between the compressor 38, the condenser 33, and the evaporator 32. After being compressed by the compressor 38, the refrigerant enters the condenser 33, where it heats the airflow. The refrigerant in the condenser 33 then enters the evaporator 32, where it absorbs heat from the airflow, thereby condensing and cooling the airflow.

[0113] In some embodiments, the compressor 38 is located in the bottom area of ​​the housing 10. A first connecting pipe 39A and a second connecting pipe 39B are arranged side by side and extend upward from the bottom area of ​​the housing 10 to the top area of ​​the housing 10, respectively. The first connecting pipe 39A and the second connecting pipe 39B are arranged on the outer periphery of the drum 20 and are spaced apart from the drum 20. The bottom ends of the first connecting pipe 39A and the second connecting pipe 39B are respectively connected to the compressor 38, and the top ends of the first connecting pipe 39A and the second connecting pipe 39B respectively extend into the housing 31.

[0114] In some embodiments, the first connecting tube 39A and the second connecting tube 39B are parallel.

[0115] In some embodiments, at least one of the first connecting tube 39A or the second connecting tube 39B is a copper tube. Copper tubes are ductile, allowing the first connecting tube 39A or the second connecting tube 39B to be bent, thereby facilitating installation of the first connecting tube 39A or the second connecting tube 39B.

[0116] In some embodiments, the inlet of the evaporator 32 is located near the outlet of the condenser 33. The top ends of the first connecting pipe 39A and the second connecting pipe 39B can be connected to the inlet of the evaporator 32 and the outlet of the condenser 33, respectively. This simplifies the piping layout and facilitates the arrangement and installation of the first connecting pipe 39A and the second connecting pipe 39B.

[0117] In some embodiments, as shown in Figures 13 to 16 , the housing 31 further includes a spacer rib 316 disposed on the base 311 between the first mounting cavity 3112 and the second mounting cavity 3113, thereby creating a predetermined gap between the evaporator 32 and the condenser 33. This prevents direct contact between the evaporator 32 and the condenser 33, thereby improving the operating efficiency of the evaporator 32 and the condenser 33 and enhancing the drying efficiency of the clothing processing apparatus.

[0118] In some embodiments, as shown in Figures 8 to 11, the isolation ribs 316 extend toward the cover 313 to prevent liquid flowing through the first installation cavity 3112 from entering the second installation cavity 3113. This prevents condensed water or cleaning liquid in the condensation tank 31120 from entering the area where the condenser is located, thereby improving the operating efficiency of the condenser and the drying efficiency of the clothes processing device.

[0119] In some embodiments, the first mounting cavity 3112, the second mounting cavity 3113, and the second air duct 3103 are respectively formed by recessing a surface of the base 311 (e.g., the upper surface) near the cover 313 toward a direction (e.g., downward) away from the cover 313. When the cover 313 is placed on the base 311, the cover 313 can simultaneously close the top openings of the first mounting cavity 3112, the second mounting cavity 3113, and the second air duct 3103.

[0120] In some embodiments, as shown in FIG15 , the housing 31 includes a first pipe joint 315 . The first pipe joint 315 is protruded from the outer wall of the base 311 and is opposite to and communicates with the air inlet of the fan 340 .

[0121] In some embodiments, the first pipe joint 315 is arranged upwardly and tilted, such that the outer end of the first pipe joint faces upward and toward a side away from the central axis of the drum 20. Therefore, when the air inlet of the fan 340 is connected to the first pipe joint, the fan 340 can be tilted toward the central axis of the drum 20. The fan 340 is located on one side of the top area of ​​the drum 20, fully utilizing the space above the drum 20 while maintaining a predetermined gap between the fan 340 and the inner wall of the housing 10 and the outer wall of the drum 20.

[0122] In some embodiments, as shown in FIG. 9 , the drying device 30 further includes a return air duct 39C (such as a bellows, etc.); the return air duct 39C connects the inner cavity 200 with the second air guide duct 3103 .

[0123] In some embodiments, the return air duct 39C is made of a shock-absorbing material to prevent vibrations generated by the drum 20 from being transmitted to the base 311. The return air duct 39C is made of a heat-insulating material to prevent the temperature around the return air duct 39C from being too high, thereby extending the service life of electrical components around the return air duct 39C.

[0124] In some embodiments, as shown in Figures 11 to 16 , the end of the second air guide duct 3103 away from the first air inlet 3112A has a second pipe joint 317. One end of the return air duct 39C is detachably connected to the second pipe joint, and the other end of the return air duct 39C is detachably connected to the exhaust port 20B. Thus, the second air guide duct 3103 is connected to the return air duct 39C, allowing air flowing through the inner cavity of the drum 20 to flow sequentially through the return air duct 39C, the second air guide duct 3103, and into the air duct body 3100.

[0125] In some embodiments, the hot and humid air flowing through the inner cavity 200 of the drum 20 can sequentially enter the first installation cavity 3112 through the exhaust port 20B of the drum 20, the return air duct 39C, and the first air inlet 3112A of the first installation cavity 3112, and then come into contact with the evaporator 32. The evaporator 32 condenses and dehumidifies the hot and humid airflow, thereby removing moisture from the airflow and lowering the temperature of the airflow to form dry and cold air. The dry and cold air then enters the second installation cavity 3113, comes into contact with the condenser 33, and is heated by the condenser 33 to form dry and hot air. The dry and cold air then passes through the first air duct outlet 310B and the fan assembly 34, and then enters the inner cavity 200 of the drum 20 through the second air inlet of the drum 20 to dry the clothes. The hot and humid air generated by the clothes in the inner cavity 200 of the drum 20 during the drying process enters the return air duct 39C from the exhaust port 20B of the drum 20, and this cycle is repeated until the program stops or the clothes in the inner cavity 200 of the drum 20 are dried, finally realizing the drying function of the clothes.

[0126] In some embodiments, as shown in Figures 7 and 8, the laundry processing device further includes a detergent dispensing assembly 60, which is fixedly connected to the housing 31. For example, the detergent dispensing assembly 60 is located on the bottom surface of the base 311, and the detergent dispensing assembly 60 is located on a side of the base 311 near the first mounting cavity 3112.

[0127] In some embodiments, the detergent dispensing assembly 60 is detachably connected to the base 311. Alternatively, the detergent dispensing assembly 60 and the base 311 are integrally formed.

[0128] In some embodiments, the base 311 is located above the top of the drum 20, the first installation cavity 3112 and the second installation cavity 3113 are located directly above the top of the drum 20, and the detergent dispensing assembly 60 is located on one side of the top of the drum 20. The detergent dispensing assembly 60 and the fan assembly 34 are located on opposite sides of the top of the drum 20. This fully utilizes the installation space in the top area of ​​the housing 10, which helps reduce the size of the laundry processing device.

[0129] In some embodiments, the filter assembly 40 is located between the detergent dispensing assembly 60 and the first installation cavity 3112. Therefore, compared to placing the filter assembly 40 above the detergent dispensing assembly 60, the distance between the filter assembly 40 and the evaporator 32 is shorter, and the airflow direction changes less, thereby shortening the airflow path from the drum 20 to the evaporator 32 and reducing wind resistance. Furthermore, the installation space in the top area of ​​the housing 10 is fully utilized, which helps reduce the volume of the laundry processing apparatus 1.

[0130] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that a person skilled in the art can conceive within the technical scope disclosed in the present disclosure should be included within the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.

[0131] Those skilled in the art will understand that the scope of the present invention is not limited to the above specific embodiments, and that certain elements of the embodiments may be modified and replaced without departing from the spirit of the present application.
