[0031] Next, exemplary embodiments of the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are used so that this disclosure will be thorough and complete, and will fully convey the concept of these exemplary embodiments to those skilled in the art.

[0032] FIG. 1 is a structural schematic diagram of a laundry treatment device provided by a first embodiment of the present application. As shown in FIG. 1, the laundry treatment device provided by the first embodiment of the present application includes a drum A, a drying module B, and an air inlet passage 102. One end of the air inlet passage 102 communicates with the drum A, and the other end communicates with the drying module B. The drum A is provided with an air outlet 60, and the air inlet passage 102 is docked with the air outlet 60. A filter mesh 103 is obliquely provided within the air inlet passage 102. Within the drum A, moisture-containing air flows through the air inlet passage 102 and into the drying module B. The inner cylinder of the drum A is driven by a drum drive motor to rotate around the drum axis, and the drying module B dries the wet clothes in the drum after washing is completed.

[0033] The drum A may be composed of an inner cylinder and an outer cylinder, or may be an integral structure. In one embodiment, the air outlet 60 is provided in the outer cylinder, the inner cylinder is rotatably mounted within the outer cylinder, the inner cylinder is provided with a water / air permeable hole, and the outer cylinder is made of a material that is impermeable to water and air. The drum is provided with an air outlet 60, which may be provided in the inner cylinder, the outer cylinder, or both the inner and outer cylinders may have air outlets 60. In one embodiment, the inner cylinder air outlet 60 is a water / air permeable hole provided inside, and the outer cylinder air outlet 60 is a through hole provided in the outer cylinder, which is docked with an air inlet passage.

[0034] The clothing treatment device provided in the embodiments of the present application is provided with a filter mesh 103 in the air inlet passage 102 connecting the drum A and the drying module B, which can filter lint generated from the clothing in the drum A and prevent the lint from entering the drying module B, thereby improving the stability and safety of drying. The clothing treatment device can be a dryer, a clothing treatment device, or a split washing machine or dryer.

[0035] Specifically, the air inlet passage 102 includes a vertical passage 1021 communicating with the drying module B and an arcuate passage 1022 communicating with the drum A. The curvature of the arcuate passage 1022 is equal to or less than the curvature of the side surface of the drum A.

[0036] The filter mesh 103 covers the first cross section of the air inlet passage 102, and the first cross section and the axis of the vertical passage 1021 of the air inlet passage 102 form a first predetermined included angle. The first predetermined included angle is greater than or equal to 20 degrees and less than or equal to 90 degrees. For example, the first included angle may be 30, 35, or 40 degrees.

[0037] In the clothing treatment device provided by this embodiment, the filter mesh 103 is arranged to extend at an angle within the air inlet passage 102. This allows the area of ​​the filter mesh 103 to be increased so that if it is small and becomes clogged, it will not affect the gas passage efficiency. On the other hand, even if there are areas that are not sufficiently cleaned during the self-cleaning process, it will not have a significant impact on the gas passage efficiency. Furthermore, the filter mesh 103 and the flow direction of the first circulating airflow in the air inlet passage 102 form a certain angle, for example an angle of 20 degrees or more, which effectively filters out lint and allows lint embedded in the holes of the filter mesh 103 to be removed by rinsing.

[0038] 2 is a structural schematic diagram of the air inlet passage of a clothing treatment device provided by a second embodiment of the present application. As shown in FIG. 2, a self-cleaning assembly is further provided at one end of the air inlet passage 102 of the clothing treatment device provided by this embodiment, which communicates with the drying module B, and the self-cleaning assembly automatically cleans lint adhering to the filter mesh 103. In this embodiment, the self-cleaning assembly is used to spray water onto the filter mesh 103. The self-cleaning assembly includes an air inlet passage water pipe 107 (see FIG. 6), a first nozzle 104, and a second nozzle 105. The air inlet passage water pipe 107 is used to supply water to the first nozzle 104 and the second nozzle 105, which are respectively provided on both sides of the filter mesh 103, and the first nozzle 104 and the second nozzle are used to spray water onto both sides of the filter mesh 103.

[0039] The clothing treatment device provided by the embodiment of the present application sprays water onto the filter mesh 103 from both sides through the first nozzle 104 and the second nozzle provided on both sides of the filter mesh 103, thereby improving the cleaning efficiency of the filter mesh 103 and preventing clogging with lint.

[0040] Of course, the self-cleaning assembly may include only the first nozzle 104 or the second nozzle 105, and during the self-cleaning process, the first nozzle 104 or the second nozzle 105 is activated to rinse the filtering surface or the filtered surface of the filter mesh 103 to remove lint adhering thereon, thereby completing the self-cleaning of the filter mesh.

[0041] FIG. 3 is a structural schematic diagram of an air inlet passage of a clothing treatment device provided by a third embodiment of the present application. FIG. 4 is a structural schematic diagram of an air inlet passage of a clothing treatment device provided by a fourth embodiment of the present application. In the third and fourth embodiments, an air inlet passage 102 is provided to condense the moisture-containing airflow flowing through it. As shown in FIGS. 3 and 4, an air inlet passage water pipe 107 (FIG. 6) is provided at one end of the air inlet passage 102 communicating with the drying module B. The air inlet passage water pipe 107 communicates with the water inlet of the condensed water flow path and supplies water to the condensed water flow path. The air inlet passage water pipe 107 optionally supplies water to the condensed water flow path through a condensation nozzle 109. A self-cleaning assembly is further provided at one end of the air inlet passage 102 communicating with the drying module B. The self-cleaning assembly includes a self-cleaning nozzle 108. The air inlet passage water pipe 107 communicates with the self-cleaning nozzle 108 and supplies water to the self-cleaning nozzle 108, which is used to spray water onto the filter mesh 103. The self-cleaning nozzle 108 has multiple spray angles, specifically, multiple spray holes, each with a different spray angle. A filter mesh 103 is provided within the air inlet passage 102. Multiple filter holes are provided on the surface of the filter mesh 103. The diameters of the filter holes may be uniform, gradually increase or decrease in the direction away from the self-cleaning nozzle 108, or irregularly distributed, for example, gradually increasing or decreasing between the filter holes from the middle to both sides of the filter mesh. The spray area of ​​the self-cleaning nozzle 108 covers the filter mesh 103, or the water outlet end of the self-cleaning nozzle 108 is flat and extends across the entire width of the filter mesh. The water flowing out from the water outlet end flows across the entire width of the filter mesh from top to bottom, carrying away lint adhering to the filter mesh.

[0042] In one embodiment, the water outlet end of the self-cleaning nozzle 108 may be located on the actual filtering surface of the filter mesh 103 to remove lint from the entire filtering surface, and the condensation nozzle 109 may be located near the tube wall of the air inlet passage 102 or on the outer wall of the tube wall of the air inlet passage 102.

[0043] 5 is a structural schematic diagram of the air inlet passage of a laundry treatment device provided in a fifth embodiment of the present application. As shown in FIG. 5, the air inlet passage 102 provided in the fifth embodiment of the present application is provided at one end communicating with the drying module B with an air inlet passage water pipe 107, which communicates with the water inlet of the condensed water flow path to supply water to the condensed water flow path, and the air inlet passage water pipe 107 optionally supplies water to the condensed water flow path through a condensation nozzle 109. The air inlet passage 102 is further provided at one end communicating with the drying module B with a self-cleaning assembly, which includes a self-cleaning nozzle 108, which communicates with the air inlet passage water pipe 107 to supply water to the self-cleaning nozzle 108, which is used to spray water onto the filter mesh 103. Of course, the self-cleaning nozzle 108 and the condensation nozzle 109 may be connected to each other via two separate water inlet pipes, with the first water inlet pipe used to supply water to the self-cleaning nozzle 108 and the second water inlet pipe used to supply water to the condensation nozzle 109. The activation timings of the self-cleaning nozzle 108 and the condensation nozzle 109 are not completely synchronized; that is, the self-cleaning nozzle 108 may be activated only at a specific time or when the filter mesh 103 needs to be cleaned, while the condensation nozzle 109 may be activated throughout the entire drying process or for a specific period of time. Therefore, when water is supplied to the condensation nozzle 109 and the self-cleaning nozzle 108 from the air inlet passage water pipe 107, switches such as electromagnetic switches may be provided on each of the two nozzles to control the activation timing. When water is supplied to the condensation nozzle 109 and the self-cleaning nozzle 108 from separate water inlet pipes, the first water inlet pipe and the second water inlet pipe may be provided with switches to control opening and closing.

[0044] In one embodiment, a condensation casing 106 is sleeved on the outer wall of the air inlet passage 102, forming a condensation flow path between the inner wall of the condensation casing 106 and the outer wall of the air inlet passage 102. The water outlet of the condensation flow path may be connected to the water outlet of the drum A or to the external environment. As the condensation flows through the condensation flow path, it cools the steam-containing airflow that has flowed through the air inlet passage 102 to a certain extent, and some of the water vapor that flows through the air inlet passage 102 is condensed into liquid water, which is discharged from the air inlet passage 102 in the direction opposite to the airflow. This reduces the moisture content in the airflow and effectively improves the water removal efficiency of the drying module.

[0045] In the clothing treatment device provided by this embodiment, the condensation casing 106 is sleeved onto the outer wall of the air inlet passage 102, thereby forming a condensed water flow path between the inner wall of the condensation casing 106 and the outer wall of the air inlet passage 102, and spraying water onto the outer wall of the air inlet passage 102 achieves condensation dehumidification while preventing condensed water from scattering.

[0046] Of course, a condenser may be provided inside or outside the air inlet passage 102 to pre-dehumidify the moisture-containing airflow flowing from the drum A to the drying module B, or a condenser may be provided between the air inlet passage 102 and the air inlet segment of the circulation fan 101, thereby reducing the moisture content in the airflow entering the drying module B and improving the dehumidification efficiency of the drying module B.

[0047] 6 is a structural schematic diagram of a self-cleaning nozzle of a clothing treatment device provided by a sixth embodiment of the present application. As shown in FIG. 6, the self-cleaning nozzle 108 provided by the sixth embodiment of the present application includes a converter 1081 and an extension 1082. The converter 1081 communicates with the water outlet of the air inlet passage water pipe 107, and the extension 1082 extends toward the filter mesh 103. The converter 1081 is used to smooth the transition between the air inlet passage water pipe 107 and the extension 1082, allowing water to smoothly flow from the outlet of the air inlet passage water pipe 107 to the extension 1082, which has a certain span. The converter 1081 is sleeved onto the outer wall of the air inlet passage water pipe 107 or docked at the water outlet end of the air inlet passage water pipe 107 to form a strong connection. The extension 1082 has a duckbill shape, and the width of the extension 1082 gradually increases in a direction away from the self-cleaning nozzle 108, with the water outlet end of the extension 1082 having substantially the same width as the filter mesh. The thickness of the extension 1082 gradually decreases in a direction away from the self-cleaning nozzle 108. The extension 1082 and the filter mesh 103 form an angle, which may be greater than 0 degrees and less than or equal to 45 degrees, so that water ejected from the water outlet end of the extension 1082 is sprayed over the entire surface of the filter mesh or flows evenly over the entire surface of the filter mesh.

[0048] The extension 1082 of the self-cleaning nozzle 108 provided in the fourth embodiment of the present application is flat, allowing water to cover the entire width of the filter mesh 103, increasing the spray area of ​​the self-cleaning nozzle 108, and the inclination angle of the extension 1082 and the filter mesh 103 can further improve the cleaning efficiency.

[0049] 7 is a structural schematic diagram of the converting unit of the clothing treatment device according to the seventh embodiment of the present application. As shown in FIG. 7, the converting unit 1081 according to the seventh embodiment of the present application is a hose, The self-cleaning nozzle 108 further includes an angle adjustment member 1083, which is used to adjust the bending angle of the conversion part 1081. The angle adjustment member 1083 is sleeved on the outer wall of the conversion part 1081 and rotatably connected to the air inlet passage water pipe 107. The angle adjustment member 1083 may be a rotating sleeve, or may be a sliding connection member.

[0050] The conversion part 1081 provided in the sixth embodiment of the present application is used to adjust the spray direction of the extension part 1082 by rotating. During the cleaning process of the filter mesh 103, by rotating the cleaning filter mesh 103, it is possible to ensure that the cleaning area covers the entire filter mesh 103 compared to when the conversion part 1081 is fixedly installed, while avoiding water clogging the entire filter mesh 103 at the same time during cleaning and affecting the flow of the first circulating airflow.

[0051] 8 is a structural schematic diagram of a clothing treatment device provided by an eighth embodiment of the present application. As shown in FIG. 8, the clothing treatment device provided by the eighth embodiment of the present application includes a housing E, a drum A, a drying module B, an air inlet passage 102, and a filter box 50. One end of the air inlet passage 102 communicates with the drum A, and the other end communicates with the drying module B. A first opening 70 is provided on the surface of the housing E, and a second opening 80 is provided in the air inlet passage 102. The first opening 70 and the second opening 80 are fitted together, and the filter box 50 is inserted into the air inlet passage 102 through the first opening 70 and the second opening 80.

[0052] The drum door of drum A is provided at the front end of housing E, and the first opening 70 is provided at the front end of housing E. At least a portion of air inlet passage 102 is sealed to the front end of housing E, and the second opening 80 is provided in the sealed area between air inlet passage 102 and housing E. Alternatively, air inlet passage 102 is not sealed to housing E, with a certain gap between them, and first opening 70 is still provided at the front end of housing E, and second opening 80 is provided at a position corresponding to first opening 70 of air inlet passage 102.

[0053] In some embodiments, the filter box 50 has openings on the top and bottom, and a filter mesh 103 is provided within the filter box 50 .

[0054] In some embodiments, the top surface of the filter box 50 is open and the bottom surface of the filter box 50 is provided with a filter mesh 103 .

[0055] In some embodiments, the filter box 50 is provided with a filter mesh 103 on the top and bottom surfaces.

[0056] In some embodiments, the filter box 50 extends into the second opening 80 to form a sealing arrangement with the air inlet passageway, and the portion of the filter box 50 that is within the air inlet passageway 102 is provided with a sloped filter mesh 103 .

[0057] With the above settings, after the filter box 50 is installed in place, the portion of the filter box 50 that extends into the second opening 80 and is located within the air inlet passage 102 forms part of the air inlet passage 102. By installing the filter mesh 103, floating particles and other debris in the airflow flowing out of the drum A are filtered by the filter mesh, and the filtered airflow enters the drying module B along the air inlet passage 102.

[0058] In some embodiments, the air inlet passage 102 is located at the front end of the drum A and the air outlet passage 203 is located at the rear end of the drum A.

[0059] In some embodiments, the air outlet passage 203 is located at the front end of the drum A and the air inlet passage 102 extends from the rear end of the drum A to the front end of the drum A.

[0060] The air outlet passage 203 is an airflow passage through which air flows out of the drying module B and enters the drum A. By locating the openings of the air inlet passage 102 and the air outlet passage 203 at the front and rear ends of the drum A, respectively, the airflow can be made to contact the clothes to be dried in the drum A sufficiently, thereby improving drying efficiency. Of course, for convenience of the overall structural design, the air inlet passage 102 and the air outlet passage 203 may both be located at one end of the drum A, or may be located a certain distance apart.

[0061] 9 is a structural schematic diagram of a drying module of a clothes treatment device provided by a ninth embodiment of the present application. As shown in FIG. 9, the ninth embodiment of the present application provides a drying module B of a clothes treatment device, which includes a circulation fan 101, a dehumidifying module 20, a regenerating fan 301, a condensing module 40, and an air outlet passage 203. The air outlet of the dehumidifying module 20 communicates with the drum A through the air outlet passage 203. A drum door is provided at the front end of the drum A, the drying module B is provided above the drum A, and the air inlet passage 102 is provided at the rear end of the drum A.

[0062] The air inlet of circulation fan 101 communicates with the air outlet of air inlet passage 102, and the air outlet of circulation fan 101 communicates with the air inlet of dehumidifying module 20. As circulation fan 101 rotates, a pressure difference is created between the air inlet and air outlet of circulation fan 101, causing gas in drum A to flow from air inlet passage 102 into circulation fan 101, then from the air outlet of circulation fan 101 into dehumidifying module 20, and finally from dehumidifying module 20 into drum A via air outlet passage 203, thereby forming a first circulating airflow between drum A and dehumidifying module 20.

[0063] The air outlet of regenerative fan 301 communicates with dehumidifying module 20, the air inlet of regenerative fan 301 communicates with the air outlet of condensing module 40, and the air inlet of condensing module 40 communicates with dehumidifying module 20. As regenerative fan 301 rotates, a pressure difference is created between the air inlet and air outlet of regenerative fan 301, causing the gas in dehumidifying module 20 to flow into condensing module 40, then into regenerative fan 301 from the air outlet of condensing module 40, and finally into dehumidifying module 20 from regenerative fan 301, forming a second circulating airflow through dehumidifying module 20 and condensing module 40, the direction of which is shown by the arrows in Figure 9.

[0064] The dehumidifying module 20 includes a dehumidifying member housing and a dehumidifying turntable 200. The dehumidifying turntable 200 is rotatably mounted within the dehumidifying member housing via a rotating shaft. The dehumidifying turntable 200 may have a porous structure covered with a dehumidifying material, which may be cotton, fiber, zeolite, lithium chloride, molecular sieve, etc. A motor is provided within the dehumidifying member housing to drive the turntable motor of the dehumidifying turntable 200. When a humid gas flow passes through the dehumidifying turntable 200, moisture is adsorbed by the dehumidifying turntable, reducing the humidity of the gas.

[0065] The dehumidifying member housing includes a water absorption area 201 and a water drainage area 202. The water absorption area 201 is located in the first circulating airflow passage, and the water drainage area 202 is located in the second circulating airflow passage. A regenerating member, such as a heater, is provided in the water drainage area 202. The portion of the dehumidifying turntable 200 that rotates toward the water absorption area 201 adsorbs moisture from the first circulating airflow, and the portion of the dehumidifying turntable 200 that rotates toward the water drainage area 202 desorbs the adsorbed moisture under the action of the heater, and the desorbed moisture flows into the condensation module 40 together with the second circulating airflow.

[0066] The condensation module 40 is used to cool the second circulating airflow, condense some of the moisture in the second circulating airflow into liquid, and discharge the condensed liquid through a water outlet. The water outlet of the condensation module 40 may be connected to the water outlet of the drum A or may be directly connected to the external environment.
