[0070] A spray assembly 2, comprising a spray column and a spray head 24, wherein the extension direction of the spray column is parallel to the axial direction of the first filter frame 11; a plurality of spray columns are provided, and the plurality of spray columns are arranged on the first filter frame 11 at intervals along the circumference of the first filter frame 11; a spray cavity is formed inside each spray column, and a water inlet and a plurality of water outlets are formed on the side wall of each spray column; the water inlet is connected to the corresponding spray cavity and is used to transport water to the spray cavity; the plurality of water outlets are arranged at intervals along the extension direction of the spray column, and a spray head 24 is arranged at each water outlet; the spray head 24 is connected to the corresponding spray cavity and is used to spray the water in the spray cavity onto the first filter screen 13;

[0071] External water can enter the spray chamber through the water inlet, and then be sprayed toward the first filter screen 13 through the multiple water outlets and the corresponding spray heads 24 to clean the first filter screen 13.

[0072] The arrangement positions of the first filter screen 13 and the spray column are related to the spray water coverage of the spray head 24, which in turn affects the thoroughness of cleaning the filter screen, which is further explained below; the first filter screen 13 is arranged on the radial inner side of the first filter screen frame 11, and the spray column is arranged on the radial outer side of the first filter screen frame 11;

[0073] Along the radial direction of the first filter frame 11, the spray column includes a column radial inner wall 233, and the column radial inner wall 233 is arranged on the first filter frame 11; along the circumferential clockwise direction of the first filter frame 11, the spray column includes a column circumferential first wall 231 and a column circumferential second wall 232 that are arranged opposite to each other, and the column circumferential first wall 231 and / or the column circumferential second wall 232 are formed with a water outlet;

[0074] The first filter screen 13 forms a first filter screen segment between two adjacent spray columns; the spray head 24 forms a spray port, and the spray port faces the adjacent first filter screen segment; the water sprayed from the spray port can flow to the first filter screen segment, thereby cleaning the first filter screen segment;

[0075] Preferably, the cross section of the spray column is rectangular.

[0076] The spray direction of the spray head 24 is directly related to the spray effect, which is further described below; the angle between the center plane of the spray column and the spray direction of the corresponding spray head 24 is θ, and θ satisfies: 45°≤θ≤75°; preferably, θ=60°

[0077] The center plane of the spray column is a plane passing through the center line of the spray column and the axis of the first filter frame 11 , and the center line of the spray column and the axis of the first filter frame 11 are parallel.

[0078] In view of the problem that the cleaning effect is poor and the cleaning is not thorough when only the spray assembly 2 is used to clean the filter screen, the present embodiment proposes that the filter device further includes a brush assembly 3; the brush assembly 3 includes a brush holder 31, and the brush holder 31 is rotatably arranged on the radial inner side of the first filter holder 11;

[0079] A first brush 33 is provided on the side of the brush holder 31 close to the first filter 13. The extension direction of the first brush 33 is parallel to the axial direction of the first filter holder 11. The first brush 33 contacts the first filter 13 for cleaning the first filter 13. The first brush 33 can clean the first filter 13 when it rotates with the brush holder 31.

[0080] Furthermore, the filter frame also includes a second filter frame 12; the second filter frame 12 is a planar structure, and the second filter frame 12 is arranged at one axial end of the first filter frame 11; the filter screen also includes a second filter screen 14, and the second filter screen 14 is covered on the second filter frame 12; the second filter frame 12 supports the second filter screen 14, increases the filtering area of ​​the filter screen and the collection area of ​​hair debris, thereby preventing hair debris from entering the air duct downstream of the filter device;

[0081] A second brush 34 is provided on the side of the brush holder 31 close to the second filter screen 14. The extension direction of the second brush 34 is parallel to the radial direction of the first filter screen holder 11. The second brush 34 contacts the second filter screen 14 and is used to clean the second filter screen 14. The second brush 34 can clean the second filter screen 14 when it rotates with the brush holder 31.

[0082] The brush holder 31 is arranged on the radial inner side of the first filter holder 11. The structure of the brush holder 31 affects the air flow area. The specific structure of the brush holder 31 is further described below. The brush holder 31 is in a flat plate shape. The brush holder 31 can rotate when it is subjected to the force of water sprayed toward the first filter 13.

[0083] Along the radial direction of the first filter screen frame 11, the brush frame 31 includes a frame radial inner wall 311 and a frame radial outer wall 312 which are arranged opposite to each other; the frame radial inner wall 311 is provided with a rotating shaft 32, the rotating shaft 32 is rotatably arranged in the first filter screen frame 11 and the rotating shaft 32 and the first filter screen frame 11 are arranged coaxially; the frame radial outer wall 312 is arranged close to one side of the first filter screen 13 and is provided with a first brush 33;

[0084] Along the axial direction of the first filter screen frame 11 , the brush frame 31 includes a frame axial wall 313 . The frame axial wall 313 is disposed on a side close to the second filter screen 14 and a second brush 34 is disposed on the frame axial wall 313 .

[0085] Preferably, the brush rack 31 is a rectangular structure; the length direction of the brush rack 31 is parallel to the axial direction of the first filter rack 11, and the width direction of the brush rack 31 is parallel to the radial direction of the first filter rack 11; the length of the brush rack 31 is consistent with the axial length of the first filter rack 11, and the width of the brush rack 31 is consistent with the radius of the first filter rack 11.

[0086] In view of the problem that the brush holder 31 has a poor effect of cleaning the filter when it rotates in a single direction on the radial inner side of the first filter holder 11, the present embodiment proposes that the spray column includes a first spray column 21 and a second spray column 22, and the column circumferential second wall 232 of the first spray column 21 is formed with a first water outlet 215, and the column circumferential first wall 231 of the second spray column 22 is formed with a second water outlet 225;

[0087] External water enters the spray chamber of the first spray column 21 from the water inlet of the first spray column 21, and then is sprayed out through the first water outlet 215 of the first spray column 21 and the corresponding spray head 24; when the spray head 24 at the first water outlet 215 of the first spray column 21 sprays water to the first filter screen 13, the water is sprayed from the outside of the first filter screen frame 11 to the inside of the first filter screen frame 11 and acts on the brush frame 31, and a clockwise torque is applied to the brush frame 31, so that the brush frame 31 can rotate clockwise;

[0088] External water enters the spray chamber of the second spray column 22 from the water inlet of the second spray column 22, and then is sprayed out through the second water outlet 225 of the second spray column 22 and the corresponding spray head 24; when the spray head 24 at the second water outlet 225 of the second spray column 22 sprays water to the first filter screen 13, the water is sprayed from the outside of the first filter screen frame 11 to the inside of the first filter screen frame 11 and acts on the brush frame 31, and a counterclockwise torque is applied to the brush frame 31, so that the brush frame 31 can rotate counterclockwise;

[0089] The water sprayed by the spray head 24 can not only clean the filter, but also drive the brush holder 31 to rotate, which can meet the needs of spraying and flushing in different directions, ensuring better cleaning effect; when the brush holder 31 rotates, the brush can clean the corresponding filter, realizing double cleaning of the filter by water flushing and brushing, accelerating the cleaning speed and doubling the cleaning force, avoiding hair debris from entering the air duct to cause air duct blockage and breeding bacteria, ensuring smooth and continuous flow of drying airflow, and improving drying efficiency; thorough and comprehensive cleaning improves user experience, and solves the problems of hair debris accumulation caused by no filter in the air duct, or hair debris residue and unclean cleaning caused by unsatisfactory hair debris cleaning effect on the filter.

[0090] The spray heads 24 at the first water outlet 215 and the second water outlet 225 are controlled to spray water, so that the brush holder 31 can rotate clockwise or counterclockwise, which is further described below; a first spray valve is provided at the water inlet of the first spray column 21, and external water can enter the corresponding spray chamber through the first spray valve; a second spray valve is provided at the water inlet of the second spray column 22, and external water can enter the corresponding spray chamber through the second spray valve; preferably, both the first spray valve and the second spray valve are solenoid valves;

[0091] The first spray valve and the second spray valve can be controlled to open or close; by controlling the opening and closing of the first spray valve and the second spray valve, the brush holder 31 can be rotated clockwise or counterclockwise;

[0092] Specifically, the first spray valve is controlled to be opened and the second spray valve is controlled to be closed, and external water enters the spray chamber of the first spray column 21 from the water inlet of the first spray column 21, and is sprayed out through the first water outlet 215 and the corresponding spray head 24, and then the water is sprayed from the outside of the first filter frame 11 to the inside of the first filter frame 11. When the water acts on the first filter 13, the first filter 13 can be cleaned; when the water acts on the brush frame 31, a clockwise torque is applied to the brush frame 31, so that the brush frame 31 can rotate clockwise, and then the first brush 33 can clean the first filter 13, and the second brush 34 can clean the second filter 14;

[0093] The second spray valve is controlled to be opened and the first spray valve is controlled to be closed, and external water enters the spray chamber of the second spray column 22 from the water inlet of the second spray column 22, and is sprayed out through the second water outlet 225 and the corresponding spray head 24, and then the water is sprayed from the outside of the first filter frame 11 to the inside of the first filter frame 11. When the water acts on the first filter 13, the first filter 13 can be cleaned; when the water acts on the brush frame 31, a counterclockwise torque is applied to the brush frame 31, so that the brush frame 31 can rotate counterclockwise, and then the first brush 33 can clean the first filter 13, and the second brush 34 can clean the second filter 14;

[0094] In this way, the filter can be cleaned in all directions, avoiding the situation where hair debris is impacted by water flow from a single direction when flushing, resulting in blind spots and causing hair debris to stagnate in place; by cleaning the filter through the above steps, the filter device can be fully cleaned.

[0095] In view of the problem that the brush holder 31 rotates discontinuously when the water sprayed by the spray head 24 acts on the brush holder 31, the present embodiment proposes that the first spray column 21 and the second spray column 22 are each provided with a plurality; preferably, the first spray column 21 and the second spray column 22 are each provided with four; the four first spray columns 21 are respectively a first spray A column 211, a first spray B column 212, a first spray C column 213 and a first spray D column 214, the first spray A column 211 and the first spray B column 212 are arranged adjacent to each other, the first spray C column 213 and the first spray D column 214 are arranged adjacent to each other, and the first spray A column 211 and the first spray C column 213 are in one diameter direction of the first filter holder 11, and the first spray B column 212 and the first spray D column 214 are in another diameter direction of the first filter holder 11; the spraying direction of the spray head 24 at the first water outlet 215 of the four first spray columns 21 is substantially clockwise;

[0106] The filter device is arranged at the air outlet of the outer cylinder, and one end of the first filter frame 11 on which the second filter frame 12 is arranged is arranged close to the drying fan 44, and the chip discharge port of the first filter frame 11 is arranged close to the inner part of the outer cylinder 42. Specifically, the chip discharge port of the first filter frame 11 extends between the outer cylinder 42 and the inner cylinder 43; the filter device can block the hair debris in the drying airflow at the air outlet of the outer cylinder and prevent it from entering the drying fan 44 and the drying air duct; the first filter 13 and the second filter 14 are combined to increase the filtering area of ​​the filter, and more hair debris can be collected during the drying process; the chip discharge port is used to discharge the hair debris shed by the first filter 13 and the second filter 14 to between the outer cylinder 42 and the inner cylinder 43, so that the hair debris can be discharged through the drain pipe of the outer cylinder 42;

[0107] Specifically, the axial length of the first filter 13 along the first filter 13 frame is the maximum distance between the inner cylinder wall and the air inlet of the drying fan 44, so as to ensure the maximum utilization area in the limited space; when the outer cylinder 42 drains water, the hair debris is discharged through the drain pipe with the water.

[0108] When the clothing processing equipment is running a cooling and temperature-lowering stage of a drying program, the filter screen is rinsed by controlling the first water outlet 215 and the corresponding spray head 24 to spray water, or the second water outlet 225 and the corresponding spray head 24 to spray water; at the same time, the water causes the brush holder 31 to rotate, and then the brush can scrub the filter screen, so that hair debris is separated from the filter screen, thereby improving the cleaning effect; under the influence of gravity, hair debris is discharged from the filter device through the chip discharge port, thereby achieving the purpose of thoroughly cleaning the thread debris.

[0109] This embodiment further provides a control method for a clothes processing device, wherein the clothes processing device is the clothes processing device described above; the clothes processing device is provided with a drying program, and the drying program includes a cooling and cooling stage; when the clothes processing device runs the cooling and cooling stage, specifically, when the clothes processing device starts to run the cooling and cooling stage, the control method includes:

[0110] Control the first spray valve and the second spray valve of the filter device to open alternately;

[0111] Specifically, when the first spray valve is controlled to be opened and the second spray valve is controlled to be closed, water enters the spray chamber of the first spray column 21 from the water inlet of the first spray column 21, and is sprayed out through the first water outlet 215 and the corresponding spray head 24, and then the water is sprayed from the outside of the first filter frame 11 to the inside of the first filter frame 11. When the water acts on the first filter 13, the first filter 13 can be cleaned; when the water acts on the brush frame 31, a clockwise torque is applied to the brush frame 31, so that the brush frame 31 can rotate clockwise, and then the first brush 33 can clean the first filter 13, and the second brush 34 can clean the second filter 14;

[0112] The second spray valve is controlled to be opened and the first spray valve is controlled to be closed, and external water enters the spray chamber of the second spray column 22 from the water inlet of the second spray column 22, and is sprayed out through the second water outlet 225 and the corresponding spray head 24, and then the water is sprayed from the outside of the first filter frame 11 to the inside of the first filter frame 11. When the water acts on the first filter 13, the first filter 13 can be cleaned; when the water acts on the brush frame 31, a counterclockwise torque is applied to the brush frame 31, so that the brush frame 31 can rotate counterclockwise, and then the first brush 33 can clean the first filter 13, and the second brush 34 can clean the second filter 14;

[0113] When the clothing processing device is in the cooling stage, the clothing in the inner drum 43 is cooled.

[0114] Further, controlling the first spray valve and the second spray valve to open and close alternately includes:

[0115] Determine the duration of the cool-down phase;

[0116] Determine a first preset duration and a second preset duration according to the duration of the cooling stage;

[0117] First, the first spray valve is controlled to open and the second spray valve is controlled to close, and the duration of each of the two spray valves is the first preset duration; then, the second spray valve is controlled to open and the first spray valve is controlled to close, and the duration of each of the two spray valves is the second preset duration; or,

[0118] Control the first spray valve and the second spray valve to open alternately, and the accumulated opening time of the first spray valve is the first preset time, and the accumulated opening time of the second spray valve is the second preset time;

[0119] Among them, the duration of the cooling stage can be determined according to the weight of the clothes in the inner drum 43; the sum of the first preset time and the second preset time is less than or equal to the duration of the cooling stage, and the filter can be cleaned before the drying is completed.

[0120] Specifically, when the filter is cleaned, spray in one direction first. At this time, the water sprayed by the spray head 24 flushes the filter and the lint rack at the same time. While flushing the filter, the impact force of the water flow also serves as the driving force of the brush rack 31. The brush rack 31 impacted by the water flow rotates, and the lint on the entire filter is cleaned by the brush and water at the same time. After a cycle of spraying in the same direction, spray and flush in the other direction. A cycle is defined as 1 / 2 of the duration of the cooling and cooling stage. Similarly, while flushing the filter, let the brush rack 31 rotate in the opposite direction to completely clean up the residual lint that may exist in the previous step, and then flush the filter with water.
