The present application provides a filter cleaning device, which is configured to clean a processing device equipped with a filter. The processing device equipped with a filter can be any one of household or office processing devices such as a clothing processing device, an air conditioner, a purifier, a range hood, an air filter, a dehumidifier, and a dust collector.

In one embodiment of the present application, a clothing processing device is provided, which is configured to wash, rinse, iron, dry, and the like clothing, and the clothing processing device includes a filter and a filter cleaning device involved in any of the following embodiments. The clothing processing device includes but is not limited to clothing processing devices such as washing machines, drying machines, and washing and drying machines in one. FIG. 1 illustrates a clothing processing device 1000, which includes a clothing storage device 1100 (which may be configured to include an inner drum and/or an outer drum) configured to accommodate clothing to be processed, a drying device 2000, and an air outlet duct 1300. The air outlet duct 1300 connects the clothing storage device 1100 and the drying device 2000. The air outlet duct 1300 is configured to guide the 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 can be arranged vertically or frontally, and this application does not impose any restrictions thereon.

In one embodiment of the present application, the humid air in the clothing receiving device 1100 enters the drying device 2000 after passing through the air outlet duct 1300, and the humid air enters the clothing receiving device 1100 again after being dried in the drying device 2000, so as to form a circulating airflow between the clothing receiving device 1100 and the drying device 2000.

In one embodiment of the present application, the drying device 2000 includes a moisture absorption unit and a moisture discharge unit. The moisture absorption unit is configured to absorb moisture in the airflow led out from the clothing receiving device 1100. The moisture discharge unit is configured to discharge the moisture absorbed by the moisture absorption unit to restore the dehumidification capacity of the moisture absorption unit. The filter 601 is arranged between the air outlet of the clothing receiving device 1100 and the air inlet of the drying device 2000 to filter the airflow. In one embodiment, the filter cleaning device 6200 is arranged on the non-filtering surface of the filter 601 and is configured to clean the filter 601.

In one embodiment of the present application, the drying device 2000 includes: a moisture absorption and dehumidification turntable. The moisture absorption and dehumidification turntable is rotatable. The housing is configured to accommodate the moisture absorption and dehumidification turntable. The internal space of the housing is divided into at least a moisture absorption space and a dehumidification space. The moisture absorption and dehumidification turntable rotating to the moisture absorption space serves as a moisture absorption unit. The moisture absorption and dehumidification turntable rotating to the dehumidification space serves as a dehumidification unit.

In one embodiment of the present application, the drying device 2000 may include a moisture absorption and dehumidification rotating disk and a driving part for driving the moisture absorption and dehumidification rotating disk to rotate, and a moisture absorbent configured to absorb water is provided on the moisture absorption and dehumidification rotating disk. The moisture absorbent may be zeolite, alkaline metal silicate, lithium chloride, silica gel, modified silica gel, activated alumina, etc. In one embodiment, the moisture absorbent may also be a molecular sieve (including but not limited to zeolite molecular sieve, A/X/Y type molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.), a polymer moisture absorbent, and other materials with moisture absorption properties. Among them, high molecular weight moisture absorbent, also known as polymer adsorbent, has a lower regeneration temperature than traditional silica gel, activated carbon and molecular sieve adsorbents.

In one embodiment, the moisture absorption and dehumidification rotary disc can be made of porous materials such as zeolite, molecular sieve, Metal Organic Framework (MOF) material, Covalent Organic Frameworks (COFs), nanocarbon, silicon dioxide, etc.

In one embodiment, the moisture absorption and dehumidification rotary disc may also be formed by filling with granular solid or particles made of at least one porous material mentioned above.

In one embodiment, the moisture absorption and dehumidification rotary disc can be a honeycomb-shaped or corrugated rotary disc carrying a desiccant, which can adsorb and desorb/detach the absorbed water vapor to achieve repeated desorption and regeneration.

In one embodiment, the moisture absorption and dehumidification rotating disk includes an inorganic/organic fiber carrier (such as ceramic, glass fiber, MOFs, COFs, cordierite, etc.), and the fiber carrier is coated with a moisture absorbent such as a molecular sieve, and the molecular sieve is evenly distributed between the fiber carriers and on the surface of the fiber carrier to achieve the adsorption of airflow moisture. The molecular sieve may include single crystal molecular sieves or mixed crystal molecular sieves such as A-type molecular sieves, X/Y-type molecular sieves, ZSM molecular sieves, and Beta molecular sieves.

In one embodiment of the present application, the moisture absorption and dehumidification rotary disc is divided into a moisture absorption zone and a regeneration zone by a sealing system, and the moisture absorption and dehumidification rotary disc rotates slowly under the drive of the driving unit. When the humid air in the clothing storage device 1100 passes through the moisture absorption zone of the moisture absorption and dehumidification rotary disc, a part of the moisture therein is absorbed by the moisture absorption medium in the rotary disc, and the dry air that has absorbed the moisture enters the clothing storage device 1100 to dry the clothes therein. At the same time, the rotary disc gradually becomes saturated due to the absorption of a certain amount of moisture. In the regeneration area of the dehumidification disc, another air stream can first pass through the heater, become high-temperature air and pass through the saturated disc after dehumidification, so that the adsorbed water in the disc evaporates, thereby restoring the dehumidification capacity of the disc. Normally, the humid air from the clothing storage device 1100 will carry some impurities such as lint shed by the clothes. If these impurities such as lint are not filtered, the humid air will carry these impurities into the drying device 2000 and attach to the moisture absorption and exhaust turntable, thereby causing the moisture absorption and exhaust turntable to be blocked, or the lint attached to the moisture absorption and exhaust turntable will be ignited when passing through the heater, causing damage to the moisture absorption and exhaust turntable.

Therefore, in one embodiment of the present application, as shown in FIG. 1 and FIG. 2 , a filter 601 can be arranged on the wet air flow path of the clothing receiving device 1100 to filter impurities such as lint. For example, the filter 601 can be arranged in the air outlet duct 1300 connecting the clothing receiving device 1100 and the drying device 2000. For example, to increase the filtering area of the filter 601, the filter 601 can be inclinedly arranged in the air outlet duct 1300. During the operation of the clothing processing device, if the filter 601 is not cleaned for a long time, the impurities such as lint attached thereto will block the air flow in the air outlet duct 1300, affecting the drying efficiency of the clothing processing device.

In order to remove the impurities such as lint in the filter 601, an embodiment of the present application provides a filter cleaning device 6200, which is configured to clean the impurities attached to the filter 601. The filter cleaning device 6200 can be a spray device, and the cleaning liquid sprayed by the spray device can remove the impurities attached to the filter.

In one embodiment, the clothing storage device 1100 includes an inner drum and an outer drum. The inner drum is configured to store clothing, and the outer drum is arranged on the outer side of the inner drum and is spaced a certain distance apart. The diameter of the outer drum is larger than the diameter of the inner drum, and a water hole is provided on the side wall of the inner drum, and the outer drum is configured to store washing water. The air outlet of the clothing storage device 1100 is arranged on the rear wall of the outer drum. The length of the air outlet duct 1300 (L1 shown in FIG. 1) is more than half of the diameter of the outer drum (D1 shown in FIG. 1). In this embodiment, the air outlet duct 1300 is longer, which can appropriately increase the area of the filter 601 and can increase the installation space of the filter cleaning device 6200.

As shown in FIG3 , in some embodiments of the present application, the filter cleaning device 6200 may include a driving mechanism 6210 and a spraying mechanism 6220. The driving mechanism 6210 is configured to provide a driving force to drive the spraying mechanism 6220 to move. The spraying mechanism 6220 is connected to the water supply port of the treatment device (the water supply port of the treatment device is not shown in the figure) and is configured to spray the cleaning fluid to the filter 601.

The spray mechanism 6220 includes a water supply assembly 6230 and a spray assembly 6240. The water supply assembly 6230 is connected to the water supply port of the treatment device through a water inlet 6231. The water supply assembly 6230 may include a guide structure configured to guide the cleaning fluid. The spray assembly 6240 is connected to the guide structure, and the spray assembly 6240 has a plurality of spray ports 6241 arranged at intervals. The guide structure can guide the flow path of the cleaning fluid to the spray assembly 6240.

In this embodiment, the filter 601 can be disposed between the air outlet of the clothes receiving device 1100 and the air inlet of the drying device 2000 to filter the air flow. The filter cleaning device 6200 can be disposed on the non-filtering side of the filter 601 and is configured to clean the filter 601. The driving mechanism 6210 is used in conjunction with the spray mechanism 6220 to easily realize the function of cleaning the filter 601.

Furthermore, as shown in FIG. 3 and FIG. 4 , in one embodiment, the spray mechanism 6220 includes a water supply assembly 6230 and a spray assembly 6240. As shown in FIG. 10 , the diversion structure is a water supply connector 6107 (which can be set as a water supply hose). The water supply assembly 6230 also includes a water supply pipe 6105. The water supply connector 6107 is connected to the water inlet 6231, and the water supply pipe 6105 is connected to the water supply connector 6107. The spray assembly 6240 includes a spray head 6103, and a plurality of spray ports 6241 arranged at intervals are spray holes 6104, and the spray holes 6104 are arranged on the same surface of the spray head 6103. The water supply pipe 6105 and the spray hole 6104 are arranged on two opposite surfaces of the spray head 6103.

As shown in FIG3 , the drive mechanism 6210 includes a drive motor 6101 and a transmission part, such as a gear box 6102 shown in FIG3 . 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 arranged at intervals. For example, the spray head 6103 may be similar to the structure of a shower. The spray holes 6104 may be arranged up and down in rows, or the spray holes 6104 may be arranged left and right 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, the spray holes may be arranged at equal intervals, or may be arranged irregularly, or may be randomly distributed according to a certain rule. The shortest distance between two adjacent spray holes 6104 is d3. FIG3 shows a filter cleaning device 6200, including a drive motor 6101, a gear box 6102, a spray head 6103, a water supply pipe 6105 and a filter bracket 604 (a filter 601 for filtering is arranged in the filter bracket 604). FIG5 shows a filter assembly arranged on the outer wall of the clothing storage device 1100 (the filter assembly includes a filter 601, and since FIG5 is a partial cross-sectional view of the filter assembly, the filter 601 is not directly shown in FIG5) and a filter cleaning device 6200 configured to clean the filter 601. The driving motor 6101 and the gear box 6102 cooperate to enable the spray mechanism 6220 to move in a first direction (the length direction of the spray mechanism 6220) so that the cleaning fluid (the spray fluid, which can be water or water with a detergent added) covers the upper and lower ends of the filter 601 in the first direction. The spray mechanism 6220 can rotate around the rotating shaft so that the spray fluid covers the left and right ends of the filter 601 in the second direction.

In one embodiment, the specific structure of the shower head 6103 is shown in FIG6 . FIG6 (a) is a front view of the shower head 6103. The front of the shower head 6103: the surface of the shower head 6103 facing the filter 601 (directly facing the filter 601), and FIG6 (b) is a side view of the shower head 6103. The moving distance of the spray mechanism 6220 in the first direction is greater than or equal to the shortest distance d3 between two adjacent spray holes 6104, so that the filter 601 can be directly sprayed by the spray fluid in the first direction, so as to ensure that the filter cleaning device 6200 can perform a more comprehensive cleaning on the filter 601.

In one embodiment, the spray head 6103 can rotate 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, so that the spray hole 6104 rotates at a preset speed to remove the lint and impurities attached to the filter 601.

The spray mechanism 6220 can move along the length direction of the spray mechanism 6220 so that the spray fluid covers the filter 601 in a first direction, and the length direction of the spray mechanism 6220 is the first direction. The spray mechanism 6220 rotates a first angle with the first direction as an axis (the rotation axis of the spray mechanism 6220 is parallel to the first direction) to expand the area of the filter 601 covered by the spray fluid.

In one embodiment, as shown in (c) of FIG6 , the first angle α is 5° to 45°. In (c) of FIG6 , the direction from inside to outside and perpendicular to the paper surface 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 the different widths of the filter 601. In this embodiment, the movement of the spraying mechanism 6220 is used to achieve the goal of the spraying fluid covering more than 80% of the area of the filter 601.

In one embodiment, the spray mechanism 6220 further includes a switch configured to open or close one or more of the plurality of spray holes. The switch can control the opening or closing of the spray hole. The switch can be provided as an integrally formed structure or as a plurality of discontinuous structures. As shown in FIG6 , the spray mechanism 6220 includes a first blocking block 6106. The first blocking block 6106 is provided on a side of the spray head 6103 away from the water supply pipe 6105 and is configured to block one or more of the plurality of spray holes 6104. The spray head 6103 has a cavity therein, and the first blocking block 6106 is provided in the cavity, and the first blocking block 6106 can move up and down. The first blocking block 6106 can move up and down along the first direction. In the actual application process of the filter cleaning device 6200 in the clothes processing equipment, the relative position of the spray mechanism 6220 and the filter 601 can be set to the first position, that is, the spray mechanism 6220 and the filter 601 are arranged in parallel and spaced in the first direction, and the specific parallel spacing distance can be adjusted according to the difference of the air outlet duct 1300. Continuing to refer to (b) of FIG6 , the first baffle 6106 can first block some of the spray holes 6104 below, which can, on the one hand, make the spray water pressure of the upper spray holes 6104 larger, so as to achieve the maximum cleaning effect on the upper filter 601; on the other hand, during the cleaning process of the upper filter 601, some of the fluff and impurities at the bottom of the filter 601 may also be taken away by the filtered water. After the fluff and impurities at the top of the filter 601 are cleaned, the first baffle 6106 slowly moves downward to expose more spray holes 6104, and further rinse the fluff and impurities at the middle and bottom of the filter 601. Finally, the filter 601 can be cleaned with different water pressures. Specifically, the number of spray holes 6104 that can spray fluid (spraying water volume), the speed of the spraying fluid in the spray holes 6104 (spraying water speed), and the pressure of the spraying fluid in the spray holes 6104 (spraying water pressure) can be controlled by setting a faucet/water valve.

In this embodiment, the spraying water volume, spraying water speed, spraying water pressure, and spraying angle of the spraying mechanism 6220 can be adjusted, thereby enhancing the cleaning effect of the spraying mechanism 6220 on the filter 601.

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 where the filter 601 is located is less than 90°. For example, the first plane is parallel to the plane where the filter 601 is located, and the spray mechanism 6220 is completely not in contact with the filter 601. When the angle between the first plane and the plane where the filter 601 is located is less than 90° and greater than 0°, the end of the filter 601 close to the clothing receiving device (i.e., the lower end of the spray mechanism 6220) can be arranged to contact the spray mechanism 6220.

In one embodiment, the distance between the spray mechanism 6220 and the filter 601 is in the 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 a rational design based on parameters such as the spray distance of the spray mechanism 6220 and the spatial layout of the clothing treatment device.

In one embodiment, as shown in FIG7 , FIG7 (a) illustrates the front side of the spray head 6103, that is, the side of the spray head 6103 facing the filter 601. Multiple rows/columns of spray holes 6104 may be provided on the spray head 6103. The spray holes 6104 may be arranged up and down in rows, or the spray holes 6104 may be arranged left and right 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 value ranges of d3 and d4 may be the same. In FIG7 (b), the direction facing the paper is the first direction. The rotation angle of the spray hole 6104 around the rotation axis is the second angle β. Under the premise that 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°.

In this embodiment, the spray mechanism 6220 includes a plurality of spray holes 6104 configured to spray water. The spray holes 6104 can be arranged as spray holes 6104 arranged up and down in rows, or can be arranged as spray holes 6104 arranged left and right in columns. The displacement of the spray mechanism 6220 in the first direction is greater than or equal to the minimum distance between two spray holes 6104. The angle (first angle α and/or second angle β) of the spray mechanism 6220 swinging around the rotation axis can make the spray fluid reach the edge 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 spraying fluid of the spraying mechanism 6220 reaches at least 90% of the length of the filter 601, or the spraying fluid of the spraying mechanism 6220 reaches at least 90% of the width of the filter 601.

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

In one embodiment, FIG. 8 illustrates that the air outlet duct 1300 includes a first end 1301 close to the clothing receiving device and a second end 1302 close to the drying device 2000 , and the filter 601 is arranged to span the first end 1301 and the second end 1302 of the air outlet duct 1300 .

In this embodiment, if the air outlet duct 1300 is a cylindrical structure, the filter 601 is a mesh structure with elliptical small holes. The filter 601 spans the first end 1301 and the second end 1302 of the air outlet duct 1300. Specifically, the filter 601 has a contact surface with the tube wall of the first end 1301, and the filter 601 also has a contact surface with the tube wall of the second end 1302. In this embodiment, the arrangement of the filter 601 can fully filter the airflow in the air outlet duct 1300.

In one embodiment, the spray mechanism 6220 is arranged across the first end 1301 and the second end 1302 of the air outlet duct 1300, so as to more conveniently realize the spray cleaning of the filter 601.

As shown in FIG9 , in one embodiment, the water supply assembly 6230 includes a water inlet 6231 and a water inlet 6232.

The water inlet 6232 is connected to the water inlet 6231 and is configured to provide a cleaning fluid to the spray assembly 6240. The water inlet 6232 may include a water inlet connector, which may be arranged in a position opposite to the water inlet 6231 or may be arranged in a misaligned position with the water inlet 6231.

As shown in FIG. 10 and FIG. 11 , the spray assembly 6240 includes a spray pipe 6242, which is connected to the water inlet 6232. The spray pipe 6242 has a plurality of spray ports 6241 arranged at intervals, and is configured to spray the cleaning fluid from the spray ports 6241. The shape of the spray pipe 6242 is not limited, and can be set to a cylindrical shape, a polyhedron (such as a tetrahedron, a hexahedron, an octahedron, etc.) or other shapes. The length of the spray pipe 6242 is also not limited, and can be specifically determined according to the installation position of the filter 601 and the actual installation space on the processing equipment.

In this embodiment, a specific structural form and connection method of the water supply assembly 6230 and the spray assembly 6240 are provided. The simple and effective structure can reduce the volume of the filter cleaning device 6200, save space, and facilitate installation near the filter 601.

In one embodiment, the line connecting the spray port 6241 to the central axis of the rotating spray pipe 6242 is perpendicular to the extension plane where the partition 6242-1 is located. In this embodiment, if the spray pipe 6242 is cylindrical, the spray port 6241 is arranged on the side wall farthest from the first spray branch pipe 6242-2 and the partition 6242-1.

In one embodiment, in the first direction, the pipe wall of the first spray branch pipe and the pipe wall of the second spray branch pipe are respectively provided with spray ports at intervals. The spray ports 6241 of the first spray branch pipe and the spray ports 6241 of the second spray branch pipe are arranged in a staggered manner. In this embodiment, the spray ports 6241 located on the side wall of the first spray branch pipe and the spray ports 6241 located on the side wall of the second spray branch pipe are not at the same level. The staggered arrangement of the spray ports 6241 can provide a larger spraying area.

In one embodiment, the spray pipe 6242 includes at least a first spray pipe 6242-4 and a second spray pipe 6242-5. The first spray pipe 6242-4 and the second spray pipe 6242-5 both have a bevel.

The bevel of the first spray pipe 6242-4 and the bevel of the second spray pipe 6242-5 are adapted to the position of the spray port 6241.

In this embodiment, the first section of the spray pipe 6242-4 and the second section of the spray pipe 6242-5 are in accordance with the positions of the spray port 6241, which can be understood as: when the first section of the spray pipe 6242-4 and the second section of the spray pipe 6242-5 are connected, the spray port 6241 is avoided, so that the spray ports 6241 provided on the pipe wall of each section of the spray pipe 6242 are complete and orderly. Furthermore, when the first section of the spray pipe 6242-4 and the second section of the spray pipe 6242-5 are connected, the connection can be achieved by bonding, or by a connecting portion 6242-6 as shown in FIG. 12 (for example, the connecting portion 6242-6 can be provided as a clamp).

FIG13 illustrates five spray ports 6241, namely, A, B, C, D and E. Among them, the three spray ports 6241, namely, A, B and C, illustrate 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 level, that is, the spray ports 6241 are misplaced. FIG13 enlarges the two spray ports 6241, namely, the diameter of the first hole segment 6241-1 is smaller than the diameter of the second hole segment 6241-2. Specifically, the diameter range of the first hole segment can be set to 0.2 mm to 3 mm; the diameter range of the second hole segment can be set to 0.3 mm to 5 mm. In this embodiment, on the one hand, the first hole segment 6241-1 has a smaller diameter so that the cleaning fluid has sufficient water pressure when passing through the first hole segment 6241-1, and then sprays outward through the second hole segment 6241-2; on the other hand, the second hole segment 6241-2 has a larger diameter so that a larger spraying area can be formed.

In one embodiment, the thickness of the spray pipe 6242 is TH1, the thickness of the first hole section 6241-1 is TH2, and TH1>TH2>5/8TH1. Specifically, the thickness of the wall of the spray pipe 6242 can be set to 0.3mm to 5mm (i.e. 0.3mm≤TH1≤5mm).

In this embodiment, the side of the spray assembly 6240 facing the filter 601 is a plane. The spray assembly 6240 (spray head 6103 or spray pipe 6242) can also be a curved surface, such as a spherical spray head 6103 or a cylindrical spray pipe 6242. In this embodiment, the side of the spray assembly 6240 facing the filter 601 is a curved surface.

In the embodiment shown in FIGS. 3 to 13 , the spraying mechanism 6220 sprays the cleaning fluid onto the filter 601 to a spraying area greater than or equal to 80% of the filtering area of the filter 601 .

In one embodiment, as shown in FIG. 3 and FIG. 7 , the filter 601 is provided with a limiter 602 configured to limit the movement of the spray mechanism 6220 (the spray head 6103 and/or the spray pipe 6242 ) within a preset range.

In this embodiment, the preset range is the numerical range that deviates from the original position during up and down movement or circumferential rotation, so as to prevent the spray mechanism 6220 (spray head 6103 and/or spray pipe 6242) from being misplaced/deviated.
