[0035] 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. In general, the assemblies of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in a variety of different configurations. Therefore, the detailed description of the embodiments of the present application provided in the drawings hereinafter does not limit the scope of the claimed application, but merely illustrates selected embodiments of the present application. 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.

[0036] 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.

[0037] The present application provides a filter cleaning device for cleaning filters in a clothing treatment facility. The clothing treatment facility is used for washing, rinsing, ironing, drying, and other processes for clothing. Examples of clothing treatment facilities include, but are not limited to, washing machines, dryers, and washer-dryers. FIG. 1 shows a clothing treatment facility 1000 including a clothing storage device 1100 (which may be configured to include an inner drum and an outer drum) for storing 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 guide 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 vertically or front-to-back, but are not limited thereto.

[0038] 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.

[0039] In one embodiment of the present application, the drying device 2000 includes a moisture absorption / desorption turntable and a driving unit for driving the rotation of the moisture absorption / desorption turntable, and a moisture absorbent for absorbing moisture is installed on the moisture absorption / desorption turntable. The moisture absorbent may be zeolite, alkali metal aluminosilicate, lithium chloride, silica gel, modified silica gel, activated alumina, etc.

[0040] 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 moisture-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 and passing through the saturated turntable. The moisture adsorbed in the turntable evaporates, 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 it passes through the heater, causing damage to the moisture absorption and desorption turntable.

[0041] Therefore, in one embodiment of the present application, a filter 601 for filtering out impurities such as lint can be installed in the moist air passage of the clothing storage device 1100. For example, as shown in FIG. 2, the filter 601 can be installed in the exhaust pipe 1300 connecting the clothing storage device 1100 and the drying device 2000. For example, to increase the filtering area of ​​the filter 601, the filter 601 can be installed at an angle in the exhaust pipe 1300. If the filter 601 is not cleaned for a long period of time during operation of the clothing treatment equipment, impurities such as lint adhering to the filter 601 will obstruct the flow of gas in the exhaust pipe 1300, affecting the drying efficiency of the clothing treatment device.

[0042] In order to solve the above problems, one embodiment of the present application provides a filter cleaning device for cleaning impurities adhering to a filter, wherein the filter cleaning device may be a spray device, and impurities adhering to the filter are removed by a cleaning liquid sprayed from the spray device.

[0043] As shown in FIG. 3 , in one embodiment of the present application, the filter cleaning device 6200 may include a driving mechanism and a spray mechanism. The driving mechanism includes a driving motor 6101 and a transmission unit (e.g., a gearbox 6102 shown in FIG. 3 ). The spray mechanism includes a spray head 6103 and a water supply pipe 6105. The spray head 6103 may include one or more spray holes spaced apart. For example, the spray head 6103 may have a structure similar to that of a shower head. The spray holes may be arranged vertically in rows or horizontally in columns. The spray holes may be arranged in one or more rows, or in one or more columns. The spray holes may be arranged regularly, for example, at equal intervals, irregularly, or randomly distributed according to a specific rule. As shown in FIG. 5 , the shortest distance between two adjacent spray holes 6104 is d3. FIG. 3 shows a filter cleaning device 6200 including a drive motor 6101, a gearbox 6102, a spray head 6103, a water supply pipe 6105, and a filter bracket 604 (a filter 601 that performs filtering is installed in the filter bracket 604).

[0044] 4 shows a filter cleaning device 6200 for cleaning the filter 601 installed on the outer wall of the clothing storage apparatus 1100, including at least the above-mentioned drive motor 6101, gear box 6102, spray head 6103 and filter bracket 604. Referring to FIG. 4, the drive motor 6101 and the gear box 6102 cooperate to enable the spray mechanism to move in a first direction (the length direction of the spray mechanism), so that the cleaning fluid (the spray fluid may be water or water with a cleaning agent added) covers both the upper and lower ends of the filter 601 in the first direction. The spray mechanism can rotate about a rotation axis so that the spray fluid covers both the left and right ends of the filter 601 in a second direction.

[0045] In one embodiment, the specific structure of the spray head 6103 is as shown in Figure 5. Figure 5(a) is a front view of the spray head 6103, showing the front side of the spray head 6103, i.e., the side facing the filter 601 (facing the filter 601). Figure 5(b) is a side view of the spray head 6103. Since the movement distance of the spray mechanism in the first direction is equal to or greater than the shortest distance d3 between two adjacent spray holes 6104, the spray fluid can be directly sprayed to every position on the filter 601, and leakage at any position on the filter 601 is avoided, thereby ensuring that the filter cleaning device 6200 can thoroughly clean the entire filter 601.

[0046] 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.

[0047] The spray mechanism can move along its length so that the spray fluid covers the filter 601 in a first direction, where the length of the spray mechanism is the first direction. The spray mechanism rotates at a first angle around the first direction (the rotation axis of the spray mechanism is parallel to the first direction) to increase the area of ​​the filter 601 covered by the spray fluid. In one embodiment, as shown in FIG. 5(c), the first angle α is 5° to 45°. In FIG. 5(c), the direction facing the page is the first direction. 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 ensures that the spray fluid covers more than 80% of the area of ​​the filter 601.

[0048] In one embodiment, the spray mechanism further includes a switch for opening or closing one or more of the multiple 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 multiple discontinuous structures. As shown in FIG. 5 , the spray mechanism includes a first stopper 6106. The first stopper 6106 is installed on a face of the spray head 6103 away from the water supply pipe 6105 and is used to block one or more of the multiple 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. During actual use of the clothing treatment device, the relative positions of the spray mechanism and the filter 601 can be in a first position, i.e., the spray mechanism and the filter 601 can be installed parallel to each other and spaced apart in a first direction, and the specific parallel distance can be adjusted according to the exhaust pipe 1300. Still referring to FIG. 5(b), the first stopper 6106 can first block some of the lower spray holes 6104, so that the spray water pressure of the upper spray holes 6104 can be relatively large to achieve the maximum cleaning effect on the upper filter 601. Also, during the cleaning process of the upper filter 601, some lint and impurities at the bottom 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 cleaned, the first stopper 6106 slowly moves downward to expose more spray holes 6104 and further wash away lint and impurities in the middle and bottom 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 that can spray fluid (spray water volume), the speed of the spray fluid at the spray holes 6104 (spray water velocity), and the pressure of the spray fluid at the spray holes 6104 (spray water pressure) can be controlled.

[0049] In this embodiment, the amount of water sprayed by the spray mechanism, the speed of the water sprayed, the pressure of the water sprayed, and the angle of the water sprayed can all be adjusted, thereby improving the cleaning effect of the filter 601 by the spray mechanism.

[0050] In one embodiment, the filter 601 includes opposing filtering and non-filtering surfaces, with the filtering surface being the surface of the filter 601 that the airflow first contacts. The non-filtering surface is the surface through which the airflow exits the filter mesh 601. A spray mechanism is installed on the non-filtering surface side and facing the filter 601 to remove lint and impurities filtered by the filter mesh 601 from the non-filtering surface side.

[0051] In one embodiment, the spray mechanism 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 and the filter 601 are not in complete contact. 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 filter 601 can be installed so that one end of the filter 601 closest to the clothing storage device (i.e., the lower end of the spray mechanism) contacts the spray mechanism.

[0052] In one embodiment, the distance between the spray mechanism and the filter 601 is in the range of 0.4 cm to 1 cm. For example, the distance between the spray mechanism 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 and the filter 601 provided in this embodiment is reasonably designed according to parameters such as the spray distance of the spray mechanism and the spatial layout of the clothing treatment equipment.

[0053] In one embodiment, as shown in FIG. 6, (a) of FIG. 6 shows the front of the spray head 6103, i.e., the side 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. 6, 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°.

[0054] In this embodiment, the spray mechanism includes a plurality of spray holes 6104 for spraying water. The spray holes 6104 may be arranged in rows, one above the other, or in columns, one above the other. The displacement of the spray mechanism in the first direction is equal to or greater than the minimum distance between two spray holes 6104. The angle of rotation of the spray mechanism about the rotation axis (first angle α and / or second angle β) allows 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 reaches at least 80% of the area of ​​the filter 601. In one embodiment, the spray fluid of the spray mechanism reaches at least 90% of the length of the filter 601, or the spray fluid of the spray mechanism reaches at least 90% of the width of the filter 601.

[0055] 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 along its own length direction, and the drive motor 6101 drives the gear box 6102 to realize rotation of the spray mechanism along a direction perpendicular to its own length.

[0056] In one embodiment, as shown in FIG. 7, the exhaust pipe 1300 includes a first end 1301 adjacent to the clothing storage device and a second end 1302 adjacent to the drying device 2000, and the filter 601 is installed across the first end 1301 and the second end 1302 of the exhaust pipe 1300, for example, in one of two ways as shown in FIG. 7(a) or FIG. 7(b).

[0057] In this embodiment, when the exhaust pipeline 1300 has a cylindrical structure, the filter 601 has an elliptical mesh structure with second 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.

[0058] In one embodiment, the spray mechanism is installed across the first end 1301 and the second end 1302 of the exhaust line 1300 to make spray cleaning of the filter 601 easier.

[0059] In one embodiment of the present application, there is provided a method for controlling a garment treatment facility, wherein the garment treatment facility may be a garment treatment facility 1000 as shown in FIG. 1. The garment treatment facility includes the filter cleaning device described above and further includes a water supply assembly.

[0063] The control module controls the drive mechanism to rotate the spray mechanism back and forth about the axis of rotation of the spray mechanism to spray the cleaning fluid onto the filter.

[0064] In this embodiment, the filter cleaning device can independently reciprocate along a first direction, independently rotate around the rotation axis of the spray mechanism, or simultaneously reciprocate along the first direction and rotate around the rotation axis of the spray mechanism to spray onto the filter and remove clothing debris, paper scraps, cotton scraps, lint, or other impurities generated in the clothing treatment device. The control module can also adjust the amount, speed, pressure, and angle of the spray mechanism's water spray, thereby improving the cleaning effect of the spray mechanism on the filter 601.

The drying device 2000 includes a housing, a moisture absorption and desorption turntable, a moisture absorption and desorption turntable drive, a circulation fan, a regeneration fan, a regeneration heating module, a condensation module, a filter cleaning device, a memory, and a processor.
