Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0063] After a period of use, the filter of a washing machine with a drying function needs to be cleaned of lint. Existing technology requires removing the filter first and then cleaning the lint, which is a cumbersome and incomplete process. It is time-consuming and laborious, and the filter cannot maintain its optimal filtration effect. The air resistance is high, the drying efficiency is low and the drying time is long, resulting in a poor user experience.

The cleaning is more thorough and comprehensive, and the cleaning speed is fast.

[0066] Example 1

[0067] <Filtering device>

[0068] like Figures 1 to 4 As shown, this embodiment provides a filtration device for clothing processing equipment, particularly for clothing processing equipment with drying functions, such as washer-dryer combos or dryers; the filtration device includes:

[0069] The filter assembly 1 includes a filter frame and a filter screen. The filter frame includes a first filter frame 11, which is cylindrical. The filter screen includes a first filter screen 13, which covers the first filter frame 11. The first filter frame 11 supports the first filter screen 13.

[0070] The spray assembly 2 includes spray columns and spray heads 24. The extension direction of the spray columns is parallel to the axial direction of the first filter screen frame 11. Multiple spray columns are provided and are spaced apart on the first filter screen frame 11 circumferentially. Each spray column has a spray chamber inside and a water inlet and multiple water outlets are formed on the side wall of each spray column. The water inlet is connected to the corresponding spray chamber and is used to supply water to the spray chamber. Multiple water outlets are spaced apart along the extension direction of the spray columns, and a spray head 24 is provided at each water outlet. The spray head 24 is connected to the corresponding spray chamber and is used to spray the water in the spray chamber onto the first filter screen 13.

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

[0072] The placement of the first filter screen 13 and the spray column affects the coverage area of ​​the spray water from the spray head 24, which in turn affects the thoroughness of cleaning the filter screen. This will be further explained below. The first filter screen 13 is located on the radial inner side of the first filter screen frame 11, and the spray column is located on the radial outer side of the first filter screen frame 11.

[0073] Along the radial direction of the first filter screen frame 11, the spray column includes a radial inner wall 233, which is disposed on the first filter screen frame 11; along the clockwise direction of the circumference of the first filter screen frame 11, the spray column includes a circumferential first wall 231 and a circumferential second wall 232 disposed opposite to each other, and the circumferential first wall 231 and / or the circumferential second wall 232 form 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 nozzle, which faces the adjacent first filter screen segment; the water sprayed from the spray nozzle 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 spraying effect, which will be further explained below; the angle between the center plane of the spray column and the corresponding spray direction of the spray head 24 is θ, where θ satisfies: 45°≤θ≤75°; preferably, θ=60°

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

[0078] To address the issues of poor cleaning effect and incomplete cleaning when using only the spray assembly 2 to clean the filter screen, this embodiment proposes that the filter device also includes a brush assembly 3; the brush assembly 3 includes a brush holder 31, which is rotatably disposed on the radial inner side of the first filter screen frame 11.

[0079] The brush holder 31 has a first brush 33 on the side near the first filter screen 13. The extension direction of the first brush 33 is parallel to the axis of the first filter screen holder 11. The first brush 33 contacts the first filter screen 13 and is used to clean the first filter screen 13. The first brush 33 can clean the first filter screen 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 has a planar structure and is disposed at one axial end of the first filter frame 11; the filter screen also includes a second filter screen 14, which covers the second filter frame 12; the second filter frame 12 supports the second filter screen 14, increasing the filtration area and lint collection area of ​​the filter screen, thereby preventing lint from entering the downstream air duct of the filter device;

[0081] The brush holder 31 has a second brush 34 on the side near 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 located on the radial inner side of the first filter screen 11. The structure of the brush holder 31 affects the air flow area. The specific structure of the brush holder 31 will be further explained below. The brush holder 31 is flat and can rotate when subjected to the force of water sprayed onto the first filter screen 13.

[0083] Along the radial direction of the first filter screen frame 11, the brush frame 31 includes a radial inner wall 311 and a radial outer wall 312 disposed opposite to each other; the radial inner wall 311 is provided with a rotating shaft 32, which is rotatably disposed within the first filter screen frame 11 and is coaxial with the first filter screen frame 11; the radial outer wall 312 is disposed on the side close to 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 an axial wall 313, which is disposed on the side near the second filter screen 14 and is provided with a second brush 34.

[0085] Preferably, the brush holder 31 has a rectangular structure; the length direction of the brush holder 31 is parallel to the axial direction of the first filter screen holder 11, and the width direction of the brush holder 31 is parallel to the radial direction of the first filter screen holder 11; the length of the brush holder 31 is the same as the axial length of the first filter screen holder 11, and the width of the brush holder 31 is the same as the radius of the first filter screen holder 11.

[0086] In response to the problem that the brush holder 31 has poor cleaning effect on the filter screen when it rotates in a single direction on the radial inner side of the first filter screen holder 11, this embodiment proposes that the spray column includes a first spray column 21 and a second spray column 22. The first spray column 21 has a first water outlet 215 formed on the second wall 232 of its circumference, and the second spray column 22 has a second water outlet 225 formed on the first wall 231 of its circumference.

[0087] External water enters the spray chamber of the first spray column 21 through the inlet, and is then sprayed out through the first outlet 215 and the corresponding spray head 24 of the first spray column 21. When the spray head 24 at the first outlet 215 of the first spray column 21 sprays water onto 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 applies a clockwise torque 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 through the inlet of the second spray column 22, and is then sprayed out through the second outlet 225 of the second spray column 22 and the corresponding spray head 24. When the spray head 24 at the second outlet 225 of the second spray column 22 sprays water onto 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 exerts a counterclockwise torque on the brush frame 31, so that the brush frame 31 can rotate counterclockwise.

[0089] The water sprayed from the spray head 24 can both clean the filter screen and drive the brush holder 31 to rotate, satisfying spray rinsing from different directions and ensuring better cleaning results. When the brush holder 31 rotates, the brushes can clean the corresponding filter screen, achieving dual cleaning of the filter screen through water rinsing and brush washing. The cleaning speed is faster and the cleaning power is doubled, preventing lint from entering the air duct and causing air duct blockage and bacterial growth. This ensures smooth and continuous airflow during drying, improving drying efficiency. The thorough and comprehensive cleaning enhances the user experience and solves problems such as lint accumulation caused by the absence of a filter screen in the air duct, or lint residue and incomplete cleaning caused by unsatisfactory lint cleaning effect on the filter screen.

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

[0091] Both 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, by controlling the opening of the first spray valve and the closing of the second spray valve, external water enters the spray chamber of the first spray column 21 through the inlet and is sprayed out through the first outlet 215 and the corresponding spray head 24. Then, the water is sprayed from the outside of the first filter screen frame 11 to the inside of the first filter screen frame 11. When the water acts on the first filter screen 13, it can clean the first filter screen 13. When the water acts on the brush frame 31, it applies a clockwise torque to the brush frame 31, so that the brush frame 31 can rotate clockwise. Thus, the first brush 33 can clean the first filter screen 13, and the second brush 34 can clean the second filter screen 14.

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

[0094] This allows for thorough cleaning of the filter screen, preventing lint from being impacted by water flowing from the same direction and creating blind spots that cause lint to stagnate. By cleaning the filter screen using the above steps, the entire filtration system can be thoroughly cleaned.

[0095] To address the issue of discontinuous rotation of the brush holder 31 when the water sprayed from the spray head 24 acts on it, this embodiment proposes that multiple first spray columns 21 and multiple second spray columns 22 are provided; preferably, four first spray columns 21 and four second spray columns 22 are provided; the four first spray columns 21 are respectively first spray column A 211, first spray column B 212, first spray column C 213 and first spray column D 214, first spray column A 211 and first spray column B 212 are arranged adjacent to each other, first spray column C 213 and first spray column D 214 are arranged adjacent to each other, and first spray column A 211 and first spray column C 213 are arranged in one diameter direction of the first filter screen frame 11, and first spray column B 212 and first spray column D 214 are arranged in another diameter direction of the first filter screen frame 11; the spraying direction of the spray head 24 at the first water outlet 215 of the four first spray columns 21 is approximately clockwise.

[0096] The four second spray columns 22 are designated as second spray column A 221, second spray column B 222, second spray column C 223, and second spray column D 224. Second spray column A 221 and second spray column B 222 are arranged adjacent to each other, and second spray column C 223 and second spray column D 224 are arranged adjacent to each other. Second spray column A 221 and second spray column C 223 are arranged along one diameter of the first filter screen frame 11, and second spray column B 222 and second spray column D 224 are arranged along the other diameter of the first filter screen frame 11. The spray direction of the spray heads 24 at the second outlets 225 of the four second spray columns 22 is approximately counterclockwise.

[0097] Along the circumference of the first filter frame 11, in a clockwise direction, the four first spray columns 21 and the four second spray columns 22 are arranged in the following order:

[0098] First spray column A 211, first spray column B 212, second spray column A 221, second spray column B 222, first spray column C 213, first spray column D 214, second spray column C 223, and second spray column D 224;

[0099] The system controls the opening of the first spray valves corresponding to the four first spray columns 21 and the closing of the second spray valves corresponding to the four second spray columns 22. Water enters the corresponding spray chambers through the inlets of the four first spray columns 21 and is sprayed out through the corresponding first outlets 215 and spray heads 24. The water sprayed from the spray heads 24 corresponding to the four first spray columns 21 is sprayed from the outside of the first filter screen frame 11 to the inside of the first filter screen frame 11. When the water acts on the first filter screen 13, it can clean the first filter screen 13. When the water acts on the brush frame 31, it applies a clockwise torque to the brush frame 31, causing the brush frame 31 to rotate clockwise. As a result, the first brush 33 can clean the first filter screen 13, and the second brush 34 can clean the second filter screen 14.

[0100] The system controls the opening of the second spray valves corresponding to the four second spray columns 22 and the closing of the first spray valves corresponding to the four first spray columns 21. Water enters the corresponding spray chambers through the inlets of the four second spray columns 22 and is sprayed out through the corresponding second outlets 225 and spray heads 24. The water sprayed from the spray heads 24 corresponding to the four second spray columns 22 is sprayed from the outside of the first filter screen frame 11 to the inside of the first filter screen frame 11. When the water acts on the first filter screen 13, it can clean the first filter screen 13. When the water acts on the brush frame 31, it applies a counterclockwise torque to the brush frame 31, so that the brush frame 31 can rotate counterclockwise. Thus, the first brush 33 can clean the first filter screen 13, and the second brush 34 can clean the second filter screen 14.

[0101] This ensures that water can fully cover the filter screen and can drive the brush holder 31 to rotate clockwise and counterclockwise, improving the cleaning effect.

[0102] It should be noted that the number of the first spray column 21 and the second spray column 22 is not limited, as long as the water sprayed through the first water outlet 215 and the corresponding spray head 24 can drive the brush frame 31 to rotate clockwise, and the water sprayed through the second water outlet 225 and the corresponding spray head 24 can drive the brush frame 31 to rotate counterclockwise.

[0103] In addition, a lint discharge port is formed at the other axial end of the first filter screen frame 11 for discharging the lint that falls off the first filter screen 13 and the second filter screen 14; the lint that falls off the first filter screen 13 and the second filter screen 14 can be discharged through the lint discharge port.

[0104] <Clothing Processing Equipment and Control Methods>

[0105] like Figure 5 As shown, this embodiment also proposes a garment processing device, which includes a housing 41, an outer cylinder 42, an inner cylinder 43, a drying fan 44, a drying duct, and a filtration device as described above. The outer cylinder 42 is disposed inside the housing 41 and includes an outer cylinder wall and an outer cylinder opening. The outer cylinder wall forms an outer cylinder air outlet, and the outer cylinder opening is provided with an outer cylinder air inlet. The inner cylinder 43 is rotatably disposed inside the outer cylinder 42. The inner cylinder 43, outer cylinder 42, outer cylinder air outlet, drying fan 44, drying duct, and outer cylinder air inlet are sequentially connected to form a drying circuit, in which drying airflow can circulate. The drying fan 44 is used to provide power for the circulating flow of the drying airflow.

[0106] The filter device is located at the air outlet of the outer cylinder, and the end of the first filter frame 11 with the second filter frame 12 is located near the drying fan 44. The lint discharge port of the first filter frame 11 is located near the inside of the outer cylinder 42. Specifically, the lint 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 lint in the drying airflow at the air outlet of the outer cylinder, preventing it from entering the drying fan 44 and the drying air duct. The combination of the first filter screen 13 and the second filter screen 14 increases the filtration area of ​​the filter screen, which can collect more lint during the drying process. The lint discharge port is used to discharge the lint that falls off the first filter screen 13 and the second filter screen 14 to the space between the outer cylinder 42 and the inner cylinder 43, so that the lint can be discharged through the drain pipe of the outer cylinder 42.

[0107] Specifically, the axial length of the first filter screen 13 along the first filter screen 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 a limited space; when the outer cylinder 42 drains water, the lint is discharged through the drain pipe with the water flow.

[0108] During the cooling and temperature reduction stage of the drying program in the garment processing equipment, water is sprayed from the first water outlet 215 and the corresponding spray head 24, or from the second water outlet 225 and the corresponding spray head 24, to rinse the filter screen. At the same time, the water causes the brush holder 31 to rotate, which allows the brush to scrub the filter screen, removing lint and improving the cleaning effect. Under the influence of gravity, the lint is discharged from the filter device through the lint discharge port, achieving the purpose of thoroughly cleaning lint.

[0109] This embodiment also proposes a control method for a garment processing device, wherein the garment processing device is as described above; the garment processing device is equipped with a drying program, which includes a cooling stage; specifically, when the garment processing device starts operating the cooling stage, the control method includes:

[0110] The first and second spray valves of the control filter are opened alternately.

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

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

[0113] During the cooling and temperature reduction stage, the clothing processing equipment cools and reduces the temperature of the clothing inside the inner drum 43.

[0114] Furthermore, controlling the alternating opening and closing of the first spray valve and the second spray valve includes:

[0115] Determine the duration of the cooling and temperature reduction phase;

[0116] The first preset duration and the second preset duration are determined based on the duration of the cooling and temperature reduction phase.

[0117] First, control the first spray valve to open and the second spray valve to close, both for a first preset duration; then control the second spray valve to open and the first spray valve to close, both for a second preset duration; or,

[0118] The first spray valve and the second spray valve are controlled to open alternately, and the cumulative time for the first spray valve to be open is a first preset time, and the cumulative time for the second spray valve to be open is a second preset time.

[0119] The duration of the cooling and heat-reducing stage can be determined based on the weight of the clothes inside the inner drum 43; the sum of the first preset duration and the second preset duration is less than or equal to the duration of the cooling and heat-reducing stage, so that the filter screen can be cleaned before the drying is finished.

[0120] Specifically, when the filter is cleaned, spraying begins in one direction. The water sprayed from the spray head 24 simultaneously washes the filter and the lint holder. While washing the filter, the water flow also drives the brush holder 31, causing it to rotate. This cleaning process, combining brush cleaning with water, cleans the entire filter. After one cycle of spraying in one direction, spraying in the other direction begins. One cycle is defined as half the duration of the cooling phase. Similarly, while washing the filter, the brush holder 31 rotates in the opposite direction to completely remove any remaining lint from the previous step, and then the filter is rinsed clean with water.

[0121] Example 2

[0122] Unlike Embodiment 1, the spray chamber has two spray chambers, namely the first spray chamber and the second spray chamber; the water inlet has two water inlets, namely the first water inlet and the second water inlet; the spray column also includes a radial outer wall of the column that is disposed opposite to the radial inner wall 233 of the column.

[0123] The second circumferential wall 232 of the spray column has a first outlet 215, and the interior of the spray column has a first spray chamber corresponding to the first outlet 215. The outer radial wall of the column has a first inlet corresponding to the first spray chamber. Both the first inlet and the first outlet 215 are connected to the first spray chamber.

[0124] A second outlet 225 is formed on the first wall 231 of the spray column in the circumferential direction. A second spray chamber is formed inside the spray column at a position corresponding to the second outlet 225. A second inlet is formed on the outer wall of the column in the radial direction at a position corresponding to the second spray chamber. Both the second inlet and the second outlet 225 are connected to the second spray chamber.

[0125] A first spray valve is provided at the first water inlet, and a second spray valve is provided at the second water inlet; both the first and second spray valves can be controlled to open or close; by controlling the opening and closing of the first and second spray valves, the brush holder 31 can be rotated clockwise or counterclockwise.

[0126] Specifically, the first spray valve is opened and the second spray valve is closed. External water enters the first spray chamber through the first inlet and is then sprayed through the first outlet 215 and the corresponding spray head 24 onto the adjacent first filter screen 13 and brush holder 31. When the water acts on the first filter screen 13, it can clean the first filter screen 13. When the water acts on the brush holder 31, it applies a clockwise torque to the brush, causing the brush holder 31 to rotate clockwise. The first brush 33 can clean the first filter screen 13, and the second brush 34 can clean the second filter screen 14.

[0127] The second spray valve is opened and the first spray valve is closed. External water enters the second spray chamber through the second inlet and is then sprayed through the second outlet 225 and the corresponding spray head 24 onto the adjacent first filter screen 13 and brush holder 31. When the water acts on the first filter screen 13, it can clean the first filter screen 13. When the water acts on the brush holder 31, it applies a counterclockwise torque to the brush, causing the brush holder 31 to rotate counterclockwise. The first brush 33 can clean the first filter screen 13, and the second brush 34 can clean the second filter screen 14.

[0128] When the spray head 24 at the first outlet 215 sprays water onto the first filter screen 13, the brush holder 31 can rotate clockwise; when the spray head 24 at the second outlet 225 sprays water onto the first filter screen 13, the brush holder 31 can rotate counterclockwise.

[0129] Example 3

[0130] Unlike Embodiment 1, this embodiment proposes that the spray column includes a first spray column 21 and a second spray column 22. The first spray column 21 has a first outlet 215 formed on the second wall 232 of its circumference, and the second spray column 22 has a second outlet 225 formed on the first wall 231 of its circumference.

[0131] When the spray head 24 at the first outlet 215 of the first spray column 21 sprays water onto 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 applies a clockwise torque to the brush frame 31, so that the brush frame 31 can rotate clockwise.

[0132] When the spray head 24 at the second outlet 225 of the second spray column 22 sprays water onto 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 applies a counterclockwise torque to the brush frame 31, so that the brush frame 31 can rotate counterclockwise.

[0133] Specifically, there are two of each of the first spray column 21 and the second spray column 22. The two first spray columns 21 are in one diameter direction of the first filter frame 11, and the two second spray columns 22 are in the other diameter direction of the first filter frame 11.

[0134] Furthermore, the spray column also includes a third spray column, and there are four third spray columns, with one third spray column arranged between an adjacent first spray column 21 and a second spray column 22;

[0135] The third spray column has a first outlet 215 formed on the second wall 232 of its circumference. Inside the third spray column, a spray chamber is formed at a position corresponding to the first outlet 215, and the spray chamber is connected to the first outlet 215. The third spray column also has a second outlet 225 formed on the first wall 231 of its circumference. Inside the third spray column, another spray chamber is formed at a position corresponding to the second outlet 225, and the spray chamber is connected to the second outlet 225.

[0136] The third spray column also includes a radial outer wall that is disposed opposite to the radial inner wall 233 of the column. The radial outer wall of the third spray column forms two water inlets. One water inlet is connected to a spray chamber, and the other water inlet is connected to another spray chamber. External water can enter the corresponding spray chamber through the two water inlets respectively, and the water in the spray chamber can be sprayed out through the corresponding water outlet and spray head 24.

[0137] When the spray head 24 at the first outlet 215 of the third spray column sprays water onto the first filter screen 13, the brush holder 31 can rotate clockwise; when the spray head 24 at the second outlet 225 of the second spray column 22 sprays water onto the first filter screen 13, the brush holder 31 can rotate counterclockwise.

[0138] A first spray valve is provided at the inlet of the first spray column 21 and at the inlet of the third spray column corresponding to the first outlet 215. A second spray valve is provided at the inlet of the second spray column 22 and at the inlet of the third spray column corresponding to the second outlet 225.

[0139] Both 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.

[0140] Specifically, when the first spray valve is opened and the second spray valve is closed, external water enters the spray chamber of the first spray column 21 through the inlet and is sprayed out through the first outlet 215 and the corresponding spray head 24 of the first spray column 21. Alternatively, external water enters the corresponding spray chamber through one inlet of the third spray column and is sprayed out through the first outlet 215 and the corresponding spray head 24 of the third spray column. Water is sprayed from the outside of the first filter screen frame 11 to the inside of the first filter screen frame 11. When the water acts on the first filter screen 13, it can clean the first filter screen 13. When the water acts on the brush frame 31, it applies a clockwise torque to the brush frame 31, allowing the brush frame 31 to rotate clockwise. Thus, the first brush 33 can clean the first filter screen 13, and the second brush 34 can clean the second filter screen 14.

[0141] When the second spray valve is opened and the first spray valve is closed, external water enters the spray chamber of the second spray column 22 through the inlet and is sprayed out through the second outlet 225 and the corresponding spray head 24. Alternatively, external water enters the corresponding spray chamber through another inlet of the third spray column and is sprayed out through the second outlet 225 and the corresponding spray head 24. Water is sprayed from the outside of the first filter screen frame 11 to the inside of the first filter screen frame 11. When the water acts on the first filter screen 13, it can clean the first filter screen 13. When the water acts on the brush frame 31, it applies a counterclockwise torque to the brush frame 31, causing the brush frame 31 to rotate counterclockwise. Thus, the first brush 33 can clean the first filter screen 13, and the second brush 34 can clean the second filter screen 14.

[0142] It should be noted that the first spray column A 211, the first spray column B 212, the first spray column C 213, and the first spray column D 214 are named to distinguish the first spray columns 21 at different locations, and are not intended to limit the structure and function of the first spray columns 21; similarly, the second spray column A 221, the second spray column B 222, the second spray column C 223, and the second spray column D 224 are named to distinguish the second spray columns 22 at different locations, and are not intended to limit the structure and function of the second spray columns 22.

It should be understood that this disclosure is not limited to the detailed structures, arrangements, or implementations described herein; rather, this disclosure is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
