DETAILED DESCRIPTION OF THE INVENTION

[0054] The following provides a clear and complete description of the technical solutions in the embodiments of the present application in accordance with the drawings in the embodiments of the present application. However, it should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments.

Based on the embodiments of the present application, a person skilled in the art can derive all other embodiments (including new embodiments formed by combining features included in different embodiments) without any creative effort, all of which fall within the scope of the claimed application.

[0055] It should be noted that similar symbols and letters represent similar items in the following drawings, so that once an item is defined in one drawing, it does not need to be further defined or interpreted in subsequent drawings. At the same time, in the description of this application, terms such as "first," "second," etc. are used only to distinguish the description, and should not be understood to indicate or imply relative importance.

[0056] As shown in Figures 1 to 7, an embodiment of the present application provides a garment treatment facility including a frame 100, a drum, and a drying device 2000. The drum can be installed within the frame 100, and can include an inner drum 200 and an outer drum 300. To minimize the overall size of the garment treatment facility, the drying device 2000 can be attached to the top of the drum, the drying device 2000 can be horizontally disposed, the outer drum 300 can be fixedly or oscillatably installed on the frame 100, the inner drum 200 can be rotatably installed within the outer drum 300, and the drive shaft of the inner drum 200 can be installed in the center of the bottom wall of the inner drum 200. The drum air inlet is located at the front or rear of the frame 100, and the drum air outlet is located at the rear or front of the frame 100, and the drum air inlet and drum air outlet are respectively connected to the space between the outer drum 300 and the inner drum 200 of the drum. The wet airflow in the drum can be converted into dry airflow through the drum exhaust port by the drying device 2000 after desorbing moisture, and the dry airflow passes through the drum intake port and enters the drum, where it fully contacts the clothes and improves drying efficiency, and so on. In one embodiment of the present application, the outer drum is provided with an exhaust port, and a filter mesh element is provided adjacent to the exhaust port, and the filter mesh element is used to capture lint in the airflow that has passed through the exhaust port. For example, the outer drum 300 may be provided with an exhaust port 310 on its bottom wall, and a filter 601 is provided in the exhaust port 310, and the filter 601 is used to capture lint in the airflow that has passed through the exhaust port 310. The airflow that has passed through the exhaust port 310 may be wet airflow from the drum that flows to the drying device 2000 through the exhaust port 310, and the inner drum 200 is rotatably mounted within the outer drum 300. In some embodiments, at least one cleaning element is provided on the side of the inner drum facing the filter mesh element, and the cleaning element rotates together with the inner drum to intermittently contact the filter mesh element and clean lint adhering to the filter mesh element.Specifically, at least one cleaning element 12 is provided on the bottom wall of the inner drum 200, protruding from the bottom wall of the inner drum 200. The cleaning element 12 intermittently contacts the filter 601 as the inner drum 200 rotates, thereby cleaning the lint from the filter 601. In another embodiment of the present application, the exhaust port 310 can be provided on the side wall of the outer drum 300, the filter 601 is provided in the exhaust port 310, and correspondingly, at least one cleaning element 12 is provided on the side wall of the inner drum 200, thereby intermittently contacting the filter 601 as the inner drum 200 rotates, thereby cleaning the lint from the filter 601. In this embodiment, the cleaning element 12 is preferably provided as a fluff strip or a scraper, and the scraper can be made of a flexible material. The inner drum 200 and the outer drum 300 may be installed approximately parallel to each other, and a certain gap may be provided between the bottom wall and the side wall of the inner drum 200 and the outer drum 300, and the cleaning element 12 may slightly protrude from the bottom wall or the side wall of the inner drum 200, and may be installed on the outer periphery of the inner drum 200 close to the bottom wall. In the rotation process, the cleaning element 12 cleans the filter 601 once every time it rotates to the exhaust port 310, and intermittently sweeps the surface of the filter 601 during the continuous circumferential rotation process of the inner drum 200, thereby The lint adhering to the filter 601 is removed by the cleaning element 12. In this way, the lint in the wet airflow flowing into the dryer 2000 through the exhaust port 310 is filtered and collected by the filter 601, preventing a large amount of lint from accumulating in the dryer 2000. Since the lint adhering to the filter 601 can be removed by the cleaning element 12, the flow rate of the wet airflow is not reduced due to clogging of the filter 601 by the lint in the wet airflow, and the drying efficiency and drying effect on the clothes can be improved, and the dryer 2000 can be protected and its service life can be extended.

[0057] In some embodiments, the cleaning element can be installed on the bottom wall or side wall of the inner drum, and correspondingly, the filter mesh element is provided near the exhaust port on the bottom wall or side wall of the outer drum. In an exemplary embodiment, the cleaning element 12 includes a lint strip or scraper, with multiple brush bristles fixed to the lint strip. The scraper can be made of a flexible material to facilitate cleaning of lint stuck to the filter 601. The cleaning element 12 can further include a mounting base plate, to which the lint strip or scraper is connected and fixed, and the mounting base plate can be removably fixed to the bottom wall or side wall of the inner drum 200 by bolts or the like. Correspondingly, the exhaust port is provided on the bottom wall or side wall of the outer drum, and the filter 601 may include a filter mesh and a framework, with the filter mesh covering one side of the framework and the other side of the framework being connected and fixed to the bottom wall or side wall of the outer drum. By covering the exhaust port with the filter mesh, the lint in the airflow flowing through the exhaust port 310 can be effectively captured. Since the filter mesh is located close to the bottom wall or side wall of the inner drum 200, during the rotation process, the cleaning element 12 cleans the filter 601 once each time it rotates to the exhaust port 310, and during the continuous circumferential rotation process of the inner drum 200, it intermittently sweeps the surface of the filter 601, thereby cleaning the lint adhering to the filter 601.

[0058] Furthermore, to improve cleaning efficiency, one embodiment further includes the following design:

[0059] The filtering and / or cleaning elements 12 can reciprocate along a direction toward or away from each other.

[0060] In some embodiments, the cleaning element 12 is configured to move away from or close to the bottom wall of the inner drum 200, and the moving direction is parallel to the rotation axis of the inner drum 200 so as to realize selective contact between the filter 601 and the cleaning element 12. When the laundry treatment equipment starts a washing or rinsing process, there is no need to extract the wet airflow in the drum to flow to the drying device 2000, so the cleaning element 12 moves in a direction close to the bottom wall of the inner drum 200, creating a gap between the cleaning element 12 and the surface of the filter 601. Thus, during the continuous circumferential rotation process of the inner drum 200, the cleaning element 12 does not come into contact with the surface of the filter 601, and there is no need to clean the filter 601. When the clothing treatment equipment starts the dehydration or drying process, it extracts the wet airflow in the drum and flows into the drying device 2000, and the lint in the wet airflow flowing into the drying device 2000 through the exhaust port 310 is filtered and captured by the filter 601, so that the cleaning element 12 moves away from the bottom wall of the inner drum 200, bringing the cleaning element 12 into contact with the surface of the filter 601, and thus, during the continuous circumferential rotation process of the inner drum 200, the cleaning element 12 intermittently sweeps the surface of the filter 601, thereby cleaning the lint stuck to the filter 601.

[0061] In some embodiments, the filter 601 is configured to move away from or close to the bottom wall of the inner drum 200, and the moving direction is parallel to the rotation axis of the inner drum 200 so that the filter 601 can selectively contact the cleaning element 12. When the laundry treatment equipment starts a washing or rinsing process, since there is no need to extract the wet airflow in the drum to flow to the drying device 2000, the filter 601 moves in a direction away from the bottom wall of the inner drum 200, creating a gap between the cleaning element 12 and the surface of the filter 601. Thus, during the continuous circumferential rotation process of the inner drum 200, the cleaning element 12 does not contact the surface of the filter 601, and there is no need to clean the filter 601. When the laundry treatment equipment starts the dehydration or drying process, the wet airflow in the drum is extracted and flows into the drying device 2000, and the lint in the wet airflow flowing into the drying device 2000 through the exhaust port 310 is filtered and collected by the filter 601, so that the cleaning element 12 moves in a direction approaching the bottom wall of the inner drum 200, bringing the cleaning element 12 into contact with the surface of the filter 601, and thus, during the continuous circumferential rotation process of the inner drum 200, the cleaning element 12 intermittently sweeps the surface of the filter 601, thereby cleaning the lint adhering to the filter 601.

[0062] In some embodiments, an exhaust pipe 1300 is provided at the exhaust port 310 of the outer drum 300, and the exhaust pipe 1300 is located on the side of the outer drum 300 that is away from the inner drum 200, and the exhaust pipe 1300 is connected to the drying device 2000 so that the wet airflow after being filtered by the filter 601 flows into the drying device 2000.

[0063] In some embodiments, the filter 601 includes a filter mesh and a fixed frame, the filter mesh is attached to the fixed frame, and the exhaust port of the outer drum is formed as a columnar hole, which the fixed frame can slide into. The filter mesh is fixably connected to one end of the fixed frame, which matches the exhaust port 310. The fixed frame can slide along the wall of the columnar hole to allow the filter 601 to move back and forth toward or away from the inner drum, and the depth of the columnar hole must meet the movement stroke of the filter 601. The fixed frame can provide good support for the filter mesh, and the exhaust port 310 is located on the bottom wall of the outer drum 300. The cross-sectional shape of the exhaust port 310 can be rectangular, circular, waist-shaped, or the like, but is not limited thereto. In the embodiment of the present application, the cross-sectional shape of the exhaust port 310 is preferably a waist-shaped hole, so that the filter 601 can be prevented from rotating during the moving process, and the waist-shaped hole design is conducive to the position estimation and movement of the filter 601, and the outer contour of the fixed frame matches the shape of the exhaust port 310.

[0064] In some embodiments, the fixed frame includes a frame, a bracket, and a probe rod, the bracket is positioned within the frame, and the ends of the bracket are connected and fixed to the frame, and the probe rod is connected to the bracket, for example, connected to the center of the bracket, and extends from the side of the bracket away from the filter mesh. The bracket can be configured in a "cross" shape, and the four ends of the bracket's periphery are respectively connected and fixed to the frame to provide good support for the filter mesh and the frame, and the probe rod is fixed to the center of the bracket, and the frame can be slid along the bottom wall of the outer drum 300 of the exhaust port 310 by pushing or pulling the probe rod, thereby improving the moving stability of the filter 601.

[0065] In some embodiments, a drive mechanism is installed on the outer drum and separated from the inner drum, and the drive mechanism is used to drive the movement of the filter mesh element. For example, the laundry processing equipment further includes a drive structure 13 connected to the filter 601 or the cleaning element 12 through transmission, and the drive structure 13 is used to drive the movement of the filter 601 or the cleaning element 12. In an exemplary embodiment, the drive structure 13 is used to drive the filter 601 to move away from or toward the bottom wall of the inner drum 200, and the direction of movement is parallel to the rotation axis of the inner drum 200 to enable the filter 601 to selectively contact the cleaning element 12. The drive structure 13 is installed on the outer drum 300, and is located on the side of the outer drum 300 away from the inner drum 200. In some embodiments, the drive structure 13 includes an electric drive device, and the active end of the electric drive device is connected to a probe rod to slide the filter 601 back and forth along the columnar hole. In an exemplary embodiment, the drive structure 13 may further include a lead screw assembly, which may include a nut and a threaded rod fitted with the nut. The electric drive device may be a servo motor or an electric drive cylinder, with the output shaft of the servo motor connected to the threaded rod via a coupling and the nut connected to the probe rod. When the servo motor is energized, it drives the rotation of the threaded rod, and the nut moves along the threaded rod, driving the movement of the probe rod and thereby driving the sliding of the probe rod along the wall of the cylindrical hole of the filter 601. When the servo motor is de-energized, the movement of the filter 601 stops. Because the transmission using the nut and the threaded rod has a self-locking function, the filter 601 can be fixed in position relative to the bottom wall of the inner drum 200, allowing the cleaning element 12 to come into contact with the surface of the filter 601. Thus, during the continuous circumferential rotation of the inner drum 200, the cleaning element 12 intermittently sweeps the surface of the filter 601, thereby removing lint adhering to the filter 601.In addition, the driving structure 13 may further include a pair of gears, the driving gear being attached to the output shaft of the servo motor and the driven gear being attached to the threaded rod, and the design of the gear pairs allows the axis of the output shaft of the servo motor to be perpendicular to the moving direction of the filter 601, thereby making the installation space of the driving structure 13 more compact. To protect the driving structure 13 from the influence of wet airflow, a protective cover may be provided on the outside of the driving structure 13, and for ease of installation and maintenance, the protective cover may extend outside the exhaust pipe 1300, and the servo motor etc. may be provided outside the exhaust pipe 1300, with the protective cover and the exhaust pipe 1300 designed to be well sealed.

[0066] During the rotation process of the inner drum 200, the cleaning element 12 cleans the filter mesh once each time it rotates near the exhaust port 310. However, the drawback is that the cleaning element 12 intermittently contacts the filter mesh during the washing, spin-drying, and drying processes. In practice, it is only necessary to clean the filter mesh during both the spin-drying and drying processes, or it is useful to clean the filter mesh only during the drying process. Therefore, the applicant of the present application has also made the following design to address this problem.

[0067] In some embodiments, the garment treatment equipment further includes a detection sensor installed in the exhaust pipe 1300 for detecting the pressure of the wet airflow after filtering by the filter 601, and a processor connected to the drive structure 13 and the detection sensor, respectively. The detection sensor transmits the detected pressure of the wet airflow to the processor, and the processor receives and processes the pressure of the wet airflow transmitted from the detection sensor. If the pressure of the wet airflow is lower than a set threshold, the processor transmits a control signal to the drive structure 13 to drive the filter 601 along the post-shaped holes in a direction approaching the inner drum 200. If the pressure of the wet airflow is higher than the set threshold, the processor transmits a control signal to the drive structure 13 to drive the filter 601 along the post-shaped holes in a direction away from the inner drum 200. To detect the wet airflow condition in the exhaust pipe 1300, a detection sensor is installed in the exhaust pipe 1300 of the outer drum 300 to determine whether there is too much lint adhering to the surface of the filter 601. When the pressure of the wet airflow drops to a certain threshold, it can be determined that there is too much lint adhering to the surface of the filter 601, and the wet airflow is blocked from entering the exhaust pipe 1300. In this case, the driving structure 13 drives the filter 601 to move a certain distance toward the inner drum 200 and stop, and the fluff strip cleans it. When the pressure of the wet airflow increases to a certain threshold, it can be determined that there is not too much lint adhering to the surface of the filter 601, and the wet airflow can smoothly enter the exhaust pipe 1300. In this case, the driving structure 13 drives the filter 601 to move in the direction away from the inner drum 200, and this process is repeated.

[0068] In some embodiments, the laundry treatment equipment further includes a processor connected to the drive structure 13. When a washing or rinsing process starts, the processor sends a control signal to the drive structure 13 to drive the filter 601 to move along the columnar holes in a direction away from the inner drum 200. When a spin-drying or drying process starts, the processor sends a control signal to the drive structure 13 to drive the filter 601 to move along the columnar holes in a direction approaching the inner drum 200. During the washing or rinsing process of laundry, the drive structure 13 drives the filter 601 to move away from the inner drum 200 and fix, and in this case, the fluff strip does not contact the surface of the filter 601. When a spin-drying or drying process starts, the drive structure 13 drives the filter 601 to move toward the inner drum 200 and fix, and in this case, the fluff strip intermittently contacts the filter mesh as the inner drum 200 rotates, thereby cleaning the filter mesh.

[0069] The present application provides a filter cleaning device arranged to clean a treatment equipment in which a filter is arranged, which may be any one of home or office treatment equipment such as a clothes treatment equipment, an air conditioner, a purifier, a range hood, an air filter, a dehumidifier, and a dust collector.

[0070] In one embodiment of the present application, a clothing treatment facility is provided that is configured to wash, rinse, iron, dry, and otherwise process clothing. The clothing treatment facility includes a filter and a filter cleaning device according to any one of the following embodiments. The clothing treatment facility may include, but is not limited to, a washing machine, a dryer, a washer-dryer, and other clothing treatment facilities. FIG. 1 shows a clothing treatment facility 1000 that includes a clothing storage device 1100 (which may be configured to include an inner drum and / or an outer drum) configured to store clothing to be treated, a drying device 2000, and an exhaust pipe 1300. The exhaust pipe 1300 connects the clothing storage device 1100 and the drying device 2000. The exhaust pipe 1300 is configured to direct airflow from the clothing storage device 1100 to the drying device 2000. The relative positions of the clothing storage device 1100 and the drying device 2000 may be arranged vertically or front-to-back, but are not limited thereto.

[0071] In one embodiment of the present application, the wet airflow in the clothing storage device 1100 passes through the exhaust pipe 1300 and then enters the drying device 2000, and after being dried by the drying device 2000, the wet airflow re-enters the clothing storage device 1100, thereby forming a circulating airflow between the clothing storage device 1100 and the drying device 2000.

[0072] In one embodiment of the present application, the drying device 2000 includes a moisture absorption unit and a moisture desorption unit. The moisture absorption unit is configured to absorb moisture in the airflow guided from the clothing storage device 1100. The moisture desorption unit is configured to expel the absorbed moisture from the moisture absorption unit to restore the dehumidifying capacity of the moisture absorption unit. A filter 601 is disposed between the air outlet of the clothing storage device 1100 and the air inlet of the drying device 2000 to filter the airflow. In one embodiment, a filter cleaning device 6200 is disposed on the non-filtering side of the filter 601 and configured to clean the filter 601.

[0073] In one embodiment of the present application, the drying device 2000 includes a moisture absorption and desorption turntable. The moisture absorption and desorption turntable is rotatable. A housing is arranged to accommodate the moisture absorption and desorption turntable. The interior space of the housing is divided into at least a moisture absorption space and a moisture desorption space. The moisture absorption and desorption turntable that rotates in the moisture absorption space functions as a moisture absorption unit. The moisture absorption and desorption turntable that rotates in the moisture desorption space functions as a moisture desorption unit.

[0074] In one embodiment of the present application, the drying device 2000 includes a moisture absorption / desorption turntable and a drive unit for driving the rotation of the moisture absorption / desorption turntable. The moisture absorption / desorption turntable is provided with a moisture absorbent arranged to absorb moisture. The moisture absorbent may be zeolite, alkali metal aluminosilicate, lithium chloride, silica gel, modified silica gel, activated alumina, or the like. In one embodiment, the moisture absorbent may also be a material with moisture absorption properties, such as a molecular sieve (including, but not limited to, zeolite molecular sieves, A / X / Y molecular sieves, ZSM molecular sieves, and Beta molecular sieves), a polymeric moisture absorbent, or the like. Here, polymeric moisture absorbents, also known as polymer adsorbents, have a lower regeneration temperature than conventional silica gel, activated carbon, and molecular sieve adsorbents.

[0075] In one embodiment, the moisture absorbing / desorbing turntable can be made of porous materials such as zeolites, molecular sieves, metal organic framework (MOF) materials, covalent organic frameworks (COFs), nanocarbons, and silicon dioxide.

[0076] In one embodiment, the moisture absorbing and releasing turntable can be formed by packing a granular solid or particles made from at least one of the porous materials described above.

[0077] In one embodiment, the moisture absorbing / desorbing turntable may be a honeycomb or wave-shaped turntable carrying a moisture absorbent, which adsorbs / desorbs absorbed water vapor, thereby achieving repeated desorption, adsorption, and regeneration.

[0078] In one embodiment, the moisture absorption / desorption turntable includes an inorganic / organic fiber support (ceramic, glass fiber, MOFs, COFs, cordierite, etc.), coated with a moisture absorbent such as a molecular sieve. The molecular sieve is uniformly distributed between and on the surface of the fiber support to absorb moisture in the airflow. The molecular sieve may be a single crystal molecular sieve or a mixed crystal molecular sieve, such as an A-type molecular sieve, an X / Y-type molecular sieve, a ZSM molecular sieve, or a Beta molecular sieve.

[0079] In one embodiment of the present application, the moisture absorption / desorption turntable is divided into a moisture absorption area and a regeneration area by a sealing system and slowly rotates by the drive. When the moist airflow in the clothing storage device 1100 passes through the moisture absorption area of ​​the moisture absorption / desorption turntable, some of the moisture is adsorbed by the moisture absorption medium in the turntable, and the absorbed dry air enters the clothing storage device 1100 and dries the clothes therein. At the same time, the turntable also absorbs a certain amount of moisture and gradually becomes saturated. In the regeneration area of ​​the moisture absorption / dehumidification turntable, air from another path first passes through a heater, becoming hot air, which then passes through the saturated turntable that has absorbed moisture, evaporating the moisture adsorbed in the turntable and restoring the turntable's dehumidifying capacity. Normally, the moist air from the clothing storage device 1100 carries some impurities such as lint that has fallen off the clothes. If these impurities such as lint are not filtered, the moist air will carry these impurities to the drying device 2000, where they will adhere to the moisture absorption and desorption turntable, causing it to clog, or the lint that has adhered to the moisture absorption and desorption turntable will be ignited when passing through the heater, causing damage to the moisture absorption and desorption turntable.

[0080] 1 and 8, a filter 601 may be installed in the flow path of moist air in the clothing storage device 1100 to filter out impurities such as lint. For example, the filter 601 may be installed in the exhaust pipe 1300 connecting the clothing storage device 1100 and the drying device 2000. For example, the filter 601 may be installed at an angle in the exhaust pipe 1300 to increase the filtering area of ​​the filter 601. If the filter 601 is not cleaned for a long period of time during the operation of the clothing treatment equipment, impurities such as lint adhering to the filter 601 may obstruct the flow of gas in the exhaust pipe 1300, affecting the drying efficiency of the clothing treatment device.

[0081] In order to remove impurities such as lint from the filter 601, one embodiment of the present application provides a filter cleaning device 6200 configured to clean the impurities adhering to the filter 601. Here, the filter cleaning device 6200 may be a spray device, and the impurities adhering to the filter are removed by spraying cleaning liquid from the spray device.

[0082] In one embodiment, the garment storage device 1100 includes an inner drum and an outer drum. The inner drum is arranged to store garments, and the outer drum is installed outside the inner drum and spaced a predetermined distance from the inner drum. The outer drum has a larger diameter than the inner drum and has water vents on its side wall, and the outer drum is arranged to store wash water. The garment storage device 1100 has an exhaust port installed on the rear wall of the outer drum. The length of the exhaust pipe 1300 (L1 shown in FIG. 1) is greater than half the diameter of the outer drum (D1 shown in FIG. 1). In this embodiment, the relatively long exhaust pipe 1300 can appropriately increase the area of ​​the filter 601 and expand the installation space of the filter cleaning device 6200.

[0083] 9, in some embodiments of the present application, a filter cleaning device 6200 may include a drive mechanism 6210 and a spray mechanism 6220. The drive mechanism 6210 is arranged to provide a drive force for moving the drive spray mechanism 6220. The spray mechanism 6220 is connected to a water inlet of a treatment facility (water inlet of the treatment facility not shown) and is arranged to spray cleaning fluid onto the filter 601 or onto a predetermined area of ​​said filter.

[0084] The spray mechanism 6220 includes a water supply assembly 6230 and a spray assembly 6240. The water supply assembly 6230 is connected to a water supply inlet of the treatment facility by a water inlet 6231. The water supply assembly 6230 may include a flow guide structure arranged to guide the clean fluid. The spray assembly 6240 is connected to the flow guide structure, and the spray assembly 6240 has a plurality of spray ports 6241 spaced apart. The flow guide structure may guide the clean fluid to the spray assembly 6240.

[0085] In this embodiment, the filter 601 can be installed between the air outlet of the clothing storage device 1100 and the air inlet of the drying device 2000 to filter the airflow. The filter cleaning device 6200 can be installed on the non-filtering side of the filter 601 and arranged to clean the filter 601. To easily realize the function of cleaning the filter mesh 601, the driving mechanism 6210 is used in combination with the spray mechanism 6220.

[0086] 9 and 10, in one embodiment, the spray mechanism 6220 includes a water supply assembly 6230 and a spray assembly 6240. Here, the flow-guiding structure shown in FIG. 10 is a water supply connection member 6107 (which can be installed on a water supply hose). The water supply assembly 6230 further includes a water supply pipe 6105. The water supply connection member 6107 is connected to a water inlet 6231, and the water supply pipe 6105 is connected to the water supply connection member 6107. The spray assembly 6240 includes a spray head 6103, and a plurality of spray orifices 6241 spaced apart are spray holes 6104, which are installed on the same surface of the spray head 6103. The water supply pipe 6105 and the spray holes 6104 are installed on two separate surfaces of the spray head 6103.

[0087] As shown in FIG. 9 , the drive mechanism 6210 includes a drive motor 6101 and a transmission unit, such as a gearbox 6102 shown in FIG. 9 . The spray mechanism 6220 includes a spray head 6103 and a water supply pipe 6105. The spray head 6103 may include one or more spray holes 6104 spaced apart. For example, the spray head 6103 may have a structure similar to that of a shower head. The spray holes 6104 may be arranged vertically in rows, or horizontally in columns. The spray holes 6104 may be arranged in one or more rows, or in one or more columns. The spray holes 6104 may be arranged regularly, for example, at equal intervals, irregularly, or randomly distributed according to a certain rule. The shortest distance between two adjacent spray holes 6104 is d3. FIG. 9 shows a filter cleaning device 6200, which includes a drive motor 6101, a gearbox 6102, a spray head 6103, a water supply pipe 6105, and a filter bracket 604 (a filter 601 is installed in the filter bracket 604 to perform filtering). FIG. 11 shows a filter assembly (the filter assembly includes a filter 601, and since FIG. 11 is a partial cross-sectional view of the filter assembly, the filter 601 is not directly shown) installed on the outer wall of the clothing storage device 1100, and a filter cleaning device 6200 arranged to clean the filter 601. A drive mechanism drives the movement of the spray mechanism in multiple directions. For example, the drive mechanism drives the movement of the spray mechanism in a first direction or a second direction, where the first direction and the second direction are perpendicular to each other. For example, by combining the drive motor 6101 and the gearbox 6102, the spray mechanism 6220 can move along a first direction (the length direction of the spray mechanism 6220), so that the cleaning fluid (the spray fluid can be water or water added with a cleaning agent) covers both the upper and lower ends of the filter 601 in the first direction. The spray mechanism 6220 can rotate around the rotation axis, so that the spray fluid covers both the left and right ends of the filter 601 in the second direction.

[0088] In one embodiment, Fig. 12 shows a specific structure of the spray head 6103. Fig. 12(a) is a front view of the spray head 6103, showing the front surface of the spray head 6103, i.e., the surface of the spray head 6103 facing the filter 601 (facing the filter 601). Fig. 12(b) is a side view of the spray head 6103. The movement distance of the spray mechanism 6220 in the first direction (i.e., the arrangement direction of the multiple spray holes) is equal to or greater than the minimum distance d3 between two adjacent spray holes 6104, so that the filter 601 is directly sprayed by the spray fluid in the first direction, thereby ensuring that the filter cleaning device 6200 can clean the filter 601 relatively thoroughly.

[0089] In one embodiment, the spray head 6103 is rotatable, so that the sprayed fluid covers the filter 601 in the second direction. In this embodiment, the rotation of the spray head 6103 can be driven by the drive motor 6101 and the gear box 6102, causing the spray holes 6104 to rotate at a preset speed to remove lint and impurities adhering to the filter 601.

[0090] The spray mechanism 6220 can move along a length of the spray mechanism 6220 such that the spray fluid covers the filter 601 in a first direction, the length of the spray mechanism 6220 being the first direction. The spray mechanism 6220 rotates a first angle about the first direction as an axis (the rotation axis of the spray mechanism 6220 is parallel to the first direction) to increase the area over which the spray fluid covers the filter 601.

[0091] In one embodiment, as shown in FIG. 12(c), the first angle α is 5° to 45°. In FIG. 12(c), the first direction is the direction from the inside to the outside, perpendicular to the paper surface and pointing inward. Specifically, the first angle α can be set to 5°, 12°, 16°, 19°, 24°, 28°, 31°, 37°, 42°, 45°, or other angles. The rotation angle of the first angle α can be selected according to different widths of the filter 601. In this embodiment, the movement of the spray mechanism 6220 ensures that the spray fluid covers more than 80% of the area of ​​the filter 601.

[0092] In one embodiment, the spray mechanism 6220 further includes a switch arranged to open or close one or more of the plurality of spray holes. The switch can control the opening or closing of the spray holes. The switch may be installed in an integrally molded structure or in a plurality of discontinuous structures. As shown in FIG. 12 , the spray mechanism 6220 includes a first stopper 6106. The first stopper 6106 is installed on a surface of the spray head 6103 away from the water supply pipe 6105 and is arranged to block one or more of the plurality of spray holes 6104. The spray head 6103 has a hollow chamber, and the first stopper 6106 is installed in the hollow chamber, and the first stopper 6106 can move up and down. The first stopper 6106 can move up and down along a first direction. When the filter cleaning device 6200 is actually used in a clothing treatment facility, the relative positions of the spray mechanism 6220 and the filter 601 can be set to a first position, i.e., the spray mechanism 6220 and the filter 601 are installed parallel and spaced apart in a first direction, and the specific parallel distance can be adjusted according to the difference in the exhaust pipe 1300. Still referring to FIG. 12(b), the first stopper 6106 can first block some of the lower spray holes 6104. On the one hand, by increasing the spray water pressure of the upper spray holes 6104, the maximum cleaning effect can be achieved on the upper filter 601. On the other hand, during the cleaning process of the upper filter 601, some lint and impurities on the lower part of the filter 601 may also be carried away by the filtered water. After the lint and impurities above the filter 601 have been thoroughly washed away, the first stopper 6106 slowly moves downward to expose more spray holes 6104, further washing away the lint and impurities in the middle and lower parts of the filter 601. Finally, the filter 601 can be cleaned with different water pressures. Specifically, by installing a faucet / water valve, the number of spray holes 6104 through which fluid can be sprayed (water volume), the speed of the spray fluid at the spray holes 6104 (water velocity), and the pressure of the spray fluid at the spray holes 6104 (water pressure) can be controlled.

[0093] In this embodiment, the spray amount, speed, pressure and angle of the spray mechanism 6220 can all be adjusted to improve the cleaning effect of the spray mechanism 6220 on the filter 601 .

[0094] In one embodiment, the spray mechanism 6220 is located in a first plane formed by the first direction and the second direction, and the angle between the first plane and the plane on which the filter 601 is located is less than 90°. For example, the first plane is parallel to the plane on which the filter 601 is located, and in this case, the spray mechanism 6220 does not make complete contact with the filter 601. When the angle between the first plane and the plane on which the filter 601 is located is less than 90° and greater than 0°, the end of the filter 601 closest to the clothing storage device (i.e., the lower end of the spray mechanism 6220) can be installed to make contact with the spray mechanism 6220.

[0095] In one embodiment, the distance between the spray mechanism 6220 and the filter 601 is within a range of 0.4 cm to 1 cm. For example, the distance between the spray mechanism 6220 and the filter 601 can be set to 0.4 cm, 0.54 cm, 0.65 cm, 0.84 cm, 0.93 cm, 1 cm, or other values. The distance between the spray mechanism 6220 and the filter 601 provided in this embodiment is reasonably designed in combination with parameters such as the spray distance of the spray mechanism 6220 and the spatial layout of the clothing treatment equipment.

[0096] In one embodiment, as shown in FIG. 13, (a) of FIG. 13 shows the front surface of the spray head 6103, i.e., the surface of the spray head 6103 facing the filter 601. The spray head 6103 may have multiple rows or columns of spray holes 6104. The spray holes 6104 may be arranged vertically in rows, or horizontally in columns. In the first direction, the shortest distance between two adjacent spray holes 6104 is d3. In the second direction, the shortest distance between two adjacent spray holes 6104 is d4. The values ​​of d3 and d4 may be in the same range. In (b) of FIG. 13, the direction facing the paper is the first direction. The rotation angle of the spray holes 6104 around the rotation axis is a second angle β. Assuming the width of the filter 601 is determined, the range of the second angle β can be smaller than the first angle α. For example, the second angle β can be set to 3° to 40°.

[0097] In this embodiment, the spray mechanism 6220 includes a plurality of spray holes 6104 arranged to spray a water stream. The spray holes 6104 may be arranged in rows of spray holes 6104 arranged above and below each other, or in columns of spray holes 6104 arranged left and right. The displacement of the spray mechanism 6220 in the first direction is equal to or greater than the minimum distance between two spray holes 6104. The swing angle (first angle α and / or second angle β) of the spray mechanism 6220 about the rotation axis can allow the spray fluid to reach the edges of the length and / or width of the filter 601. In one embodiment, the spray fluid of the spray mechanism 6220 reaches at least 80% of the area of ​​the filter 601. In one embodiment, the spray fluid of the spray mechanism 6220 reaches at least 90% of the length of the filter 601, or the spray fluid of the spray mechanism 6220 reaches at least 90% of the width of the filter 601.

[0098] In one embodiment, the clothing treatment equipment further includes a drive motor 6101 and a gear box 6102, and the drive motor 6101 drives the gear box 6102 to realize movement of the spray mechanism 6220 along its own length direction, and the drive motor 6101 drives the gear box 6102 to realize rotation of the spray mechanism 6220 along a direction perpendicular to its own length.

[0099] 14 shows an exhaust line 1300 including a first end 1301 proximate the clothing storage device and a second end 1302 proximate the drying device 2000. A filter 601 is positioned across the first end 1301 and the second end 1302 of the exhaust line 1300.

[0100] In this embodiment, when the exhaust pipeline 1300 has a cylindrical structure, the filter 601 has a mesh structure with elliptical holes. The filter 601 spans the first end 1301 and the second end 1302 of the exhaust pipeline 1300. Specifically, the filter 601 has a contact surface with the pipe wall of the first end 1301, and the filter 601 also has a contact surface with the pipe wall of the second end 1302. In this embodiment, the installation method of the filter 601 can sufficiently filter the airflow in the exhaust pipeline 1300.

[0101] In one embodiment, the spray mechanism 6220 is installed across the first end 1301 and the second end 1302 of the exhaust line 1300, making it easier to spray and clean the filter 601.

[0102] 15 , in one embodiment, the water supply assembly 6230 includes a water inlet 6231 and a water absorber 6232. The water supply assembly 6230 is connected to a water inlet of the treatment facility via the water inlet 6231. The water absorber 6232 is connected to the water inlet 6231 and is positioned to provide clean fluid to the spray assembly 6240. The water absorber 6232 may include a water intake connect, which may be located opposite the water inlet 6231 or may be located offset from the water inlet 6231.

[0103] 16 and 17, the spray assembly 6240 includes a spray pipe 6242 connected to the water absorber 6232, and the spray pipe 6242 has a plurality of spray ports 6241 spaced apart from one another and arranged to spray clean fluid from the spray ports 6241. The shape of the spray pipe 6242 is not limited and may be cylindrical, polyhedral (e.g., tetrahedron, hexahedron, octahedron, etc.), or other shapes. The length of the spray pipe 6242 is also not limited and may be determined based on the installation position of the filter 601 and the actual installation space on the treatment equipment.

[0104] In this embodiment, specific structural forms and connection methods of the water supply assembly 6230 and the spray assembly 6240 are provided, and the simple and effective structure reduces the volume of the filter cleaning device 6200, saves space, and makes it easy to install near the filter 601.

[0105] In one embodiment, the flow guide structure is a water distributor 6243. The water distributor 6243 is connected to the water suction pipe 6232, and the water distributor 6243 is arranged to guide the clean fluid to the spray pipe 6242. In this embodiment, the installation of the water distributor 6243 is such that, on the one hand, the water distributor 6243 is connected to the water suction pipe 6232 and is arranged to guide the path of the clean fluid, and on the other hand, the water distributor 6243 is connected to the spray pipe 6242 and is arranged to control the flow rate and / or flow velocity of the clean fluid entering the spray pipe 6242.

[0106] As shown in FIG. 16 , in one embodiment, the water distributor 6243 includes a first water distribution plate 6243-1 (which can be installed on a fixed plate or a static plate). The first water distribution plate 6243-1 can have first through-holes 6243-11, through which the clean fluid flows. In this embodiment, the first through-holes 6243-11 are provided in the first water distribution plate 6243-1, which facilitates control of the flow rate and / or flow velocity of the clean fluid entering the spray tube 6242. Specifically, the area of ​​the first through-holes 6243-11 occupies 10% to 90% of the area of ​​the first water distribution plate 6243-1. For example, the area of ​​the first through-holes 6243-11 can be set to half the area of ​​the first water distribution plate 6243-1. Alternatively, the area of ​​the first through-holes 6243-11 can be set to one-third of the area of ​​the first water distribution plate 6243-1.

[0107] 17, in one embodiment, the water distributor 6243 further includes a second water distribution plate (movable plate) 6243-2 (which can be installed on a movable plate). The second water distribution plate 6243-2 is movable relative to the first water distribution plate 6243-1. The second water distribution plate 6243-2 has at least a first water distribution hole 6243-21 and a second water distribution hole 6243-22. The clean fluid in the first through-hole 6243-11 flows through the first water distribution hole 6243-21 or the second water distribution hole 6243-22 to the spray pipe 6242.

[0108] In this embodiment, the water distributor 6243 includes two water distribution plates, one dynamic and one static, and the second water distribution plate 6243-2 is movable relative to the first water distribution plate 6243-1, allowing the clean fluid to enter the spray pipe 6242 through the first through-holes 6243-11 and the first water distribution holes 6243-21, or allowing the clean fluid to enter the spray pipe 6242 through the first through-holes 6243-11 and the second water distribution holes 6243-22. In this embodiment, the water distributor 6243 can be configured to appropriately adjust the flow rate and / or volume of the clean fluid after it enters the spray pipe 6242. For example, the volume of the clean fluid entering the spray pipe 6242 can be reduced. Alternatively, the flow rate of the clean fluid after it enters the spray pipe 6242 can be increased.

[0109] In one embodiment, when the second water distribution plate 6243-2 (movable plate) moves relative to the first water distribution plate 6243-1 (fixed plate), it has at least a first position and a second position. The first position is a position where the first water distribution holes 6243-21 and the first through-holes 6243-11 have overlapping projected areas in a first direction. The second position is a position where the second water distribution holes 6243-22 and the first through-holes 6243-11 have overlapping projected areas in a first direction, and the first direction is the direction in which the length of the spray tubes 6242 extends.

[0113] In one embodiment, the water distributor 6243 only includes a first water distribution plate 6243-1 having a first through-hole 6243-11. The clean fluid flows out from the first through-hole 6243-11 and then flows into the spray pipe 6242. The spray pipe 6242 has a partition member 6242-1. When the spray pipe 6242 rotates, the clean fluid flows out from the spray port 6241 on the pipe wall of the spray pipe 6242 to spray onto the filter 601.

[0114] In one embodiment, the bottom end of the spray tube 6242 is closed, which better facilitates accumulation of cleaning fluid in the spray tube 6242 and facilitates achieving a more thorough cleaning of the filter 601 .

[0115] In one embodiment, the first water distribution hole 6243-21 is located upstream of the first spray branch 6242-2, and the cross-sectional area of ​​the first water distribution hole 6243-21 is equal to or less than the cross-sectional area of ​​the first spray branch 6242-2. The second water distribution hole 6243-22 is located upstream of the second spray branch 6242-3, and the cross-sectional area of ​​the second water distribution hole 6243-22 is equal to or less than the cross-sectional area of ​​the second spray branch 6242-3.

[0116] In one embodiment, the cross-sectional area of ​​the first water distribution hole 6243-21 and / or the second water distribution hole 6243-22 accounts for 10% to 90% of the cross-sectional area of ​​the first through-hole 6243-11. For example, the cross-sectional area of ​​the first water distribution hole 6243-21 can be set to 60% of the cross-sectional area of ​​the first through-hole 6243-11, and the cross-sectional area of ​​the second water distribution hole 6243-22 can be set to 60% of the cross-sectional area of ​​the first through-hole 6243-11. The cross-sectional area of ​​the first water distribution hole 6243-21 can be set to 45% of the cross-sectional area of ​​the first through-hole 6243-11, and the cross-sectional area of ​​the second water distribution hole 6243-22 can be set to 45% of the cross-sectional area of ​​the first through-hole 6243-11.

In this embodiment, the spray ports 6241 can be arranged in a single row and / or a single column on the walls of the first spray branch 6242-2 and the second spray branch 6242-3, or the spray ports 6241 can be arranged in multiple rows and / or columns, which can be arranged in an orderly or staggered fashion.

[0118] In one embodiment, the connecting line from the spray port 6241 to the central axis of the rotary spray pipe 6242 is perpendicular to the extension plane on which the partition member 6242-1 is located. In this embodiment, when the spray pipe 6242 is cylindrical, the spray port 6241 is installed on the side wall where the first spray branch pipe 6242-2 is furthest from the partition member 6242-1.

[0119] In one embodiment, spray ports 6241 are spaced apart from one another on the wall of the first spray branch and the wall of the second spray branch in the first direction. The spray ports 6241 of the first spray branch are offset from the spray ports 6241 of the second spray branch. In this embodiment, the spray ports 6241 on the side wall of the first spray branch and the spray ports 6241 on the side wall of the second spray branch are not at the same horizontal height. The offset placement of the spray ports 6241 can provide a larger spray area.

[0120] In one embodiment, the spray pipe 6242 includes at least a first section spray pipe 6242-4 and a second section spray pipe 6242-5. The first section spray pipe 6242-4 and the second section spray pipe 6242-5 both have inclined tangent planes. The inclined tangent plane of the first section spray pipe 6242-4 is connected to the inclined tangent plane of the second section spray pipe 6242-5. The inclined tangent planes of the first section spray pipe 6242-4 and the second section spray pipe 6242-5 are adapted to the position of the spray orifice 6241.

[0121] In this embodiment, the inclined tangential plane of the first section spray pipe 6242-4 and the inclined tangential plane of the second section spray pipe 6242-5 are adapted to the position of the spray orifices 6241, which can be understood as avoiding the position of the spray orifices 6241 so that when the inclined tangential plane of the first section spray pipe 6242-4 is connected to the inclined tangential plane of the second section spray pipe 6242-5, all of the spray orifices 6241 installed on the pipe wall of each section spray pipe 6242 are complete and orderly. Furthermore, when the inclined tangential plane of the first section spray pipe 6242-4 is connected to the inclined tangential plane of the second section spray pipe 6242-5, the connection can be realized by adhesion, or the connection can be realized by the connecting part 6242-6 shown in FIG. 12 (for example, the connecting part 6242-6 can be installed on a clamp).

[0122] 19, in one embodiment, the spray port 6241 includes a first hole section 6241-1 and a second hole section 6241-2 along the thickness direction of the wall of the spray pipe 6242. The second hole section 6241-2 is located on the side of the first hole section 6241-1 away from the rotation axis of the spray pipe 6242, and the diameter of the first hole section 6241-1 is smaller than the diameter of the second hole section 6241-2. FIG. 13 shows five spray ports 6241, designated A, B, C, D, and E. Here, the three spray ports 6241, designated A, B, and C, indicate that the spray ports 6241 located on the side wall of the first spray branch pipe 6242-2 and the spray ports 6241 located on the side wall of the second spray branch pipe 6242-3 are not at the same horizontal height, i.e., the spray ports 6241 are offset. 13 shows an enlargement of two spray holes 6241, D and E. In the enlarged view, it can be seen that the diameter of the first hole section 6241-1 is smaller than the diameter of the second hole section 6241-2. Specifically, the diameter of the first hole section can be set to a range of 0.2 mm to 3 mm, and the diameter of the second hole section can be set to a range of 0.3 mm to 5 mm. In this embodiment, on the one hand, by making the diameter of the first hole section 6241-1 smaller, the clean fluid can have sufficient water pressure when passing through the first hole section 6241-1 and can then easily pass through the second hole section 6241-2 and be sprayed outward. On the other hand, by making the diameter of the second hole section 6241-2 larger, it is easy to form a larger spray area.

[0123] In one embodiment, the thickness of the spray tube 6242 is TH1, and the thickness of the first hole section 6241-1 is TH2, where TH1 > TH2 > 5 / 8TH1. Specifically, the thickness of the pipe wall of the spray tube 6242 can be set to a range of 0.3 mm to 5 mm (i.e., 0.3 mm ≦ TH1 ≦ 5 mm). For example, in one embodiment, the thickness of the rotary spray tube 6242 is 1.6 mm, and the thickness of the first hole section 6241-1 is 1.0 mm.

Furthermore, the drive motor 6101 can drive the spray tube 6242 to rotate 60° to 360° in a clockwise and / or counterclockwise direction along the rotation axis of the spray tube 6242. For example, the rotation angle of the spray tube 6242 can be 90°, 180°, 270°, or 360°. In one embodiment, the drive motor 6101 drives the rotary spray tube 6242 to rotate 360°. In another embodiment, the drive motor 6101 regulates the position of the rotary spray tube 6242 in accordance with a structure such as a connecting rod to control the reciprocating rotation of the rotary spray tube 6242 within a range of 180°.

[0126] In one embodiment, the drive mechanism 6210 includes an extendable drive motor 6101 arranged to move the spray tube 6242 up and down along the extension direction of the length of the spray tube 6242.
