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.

[0066] In existing washing machines, to improve washing performance, a spray method is used to spray and wash the clothes in the washing drum, causing substances adhering to the surface of the clothes to detach. There are two sources of water for spray washing: the first is to spray external water onto the clothes through the spray head, and the second is to recycle the water in the washing drum. The first method requires a large amount of water, which is wasteful of water resources. The second method involves the generation of lint during the washing process, which can clog the spray device, resulting in reduced spray flow and poorer spray effect. In addition, the filter self-cleaning mechanism can only drain water, which is a single function and cannot meet the spray requirements.

[0067] This invention creatively provides a filter self-cleaning mechanism for clothing processing equipment; a processing chamber is formed inside the housing, and a water inlet, a first water outlet and a second water outlet are formed on the side wall of the housing; the filter is arranged around the second water outlet; the impeller and the cleaning component are rotatably arranged in the processing chamber, and the cleaning component and the impeller can rotate simultaneously.

[0068] When the impeller rotates, water from outside the treatment chamber can enter the treatment chamber through the inlet, and water inside the treatment chamber can be discharged directly through the first outlet, thus promptly draining the water from the washing drum; or it can be filtered through the filter screen first and then discharged through the second outlet, allowing for the recycling of water in the washing drum and spray washing, ensuring spray flow and spray effect; the cleaning component can clean the lint on the filter screen as the impeller rotates; thus realizing the functions of drainage, spray washing, and lint cleaning.

[0069] Example 1

[0070] like Figures 1 to 6c As shown, this embodiment provides a filter self-cleaning mechanism for use in clothing processing equipment; the filter self-cleaning mechanism includes:

[0071] The shell 1 has a processing chamber inside it, and the side wall of the shell 1 has an inlet 131, a first outlet and a second outlet 122 that are all connected to the processing chamber.

[0072] The filter assembly 2 is disposed in the processing chamber for filtering at least a portion of the water entering the processing chamber through the inlet 131, for example, filtering out lint from the water; the filter assembly 2 includes a filter 21 disposed at the second outlet 122; the water filtered by the filter 21 is discharged from the second outlet 122.

[0073] Impeller 51, which is rotatably disposed in the treatment chamber, is used to provide power for water to flow from inlet 131 to first outlet and / or second outlet 122;

[0074] The cleaning component 3 is rotatably disposed in the processing chamber for cleaning the filter screen 21; the cleaning component 3 is connected to the impeller 51 in a driving connection; when the impeller 51 rotates, the cleaning component 3 can rotate with the impeller 51.

[0075] When the impeller 51 rotates, water outside the treatment chamber can enter the treatment chamber through the inlet 131. Water inside the treatment chamber can be discharged directly through the first outlet, or filtered through the filter screen 21 and then discharged through the second outlet 122. When the cleaning component 3 rotates with the impeller 51, it can clean the lint on the filter screen 21 in time, ensuring the water flow rate of the filter screen 21.

[0076] Furthermore, from the inlet 131 towards the inside of the treatment chamber, the flow area of ​​the inlet 131 gradually decreases, which is used to increase the pressure of the water entering the treatment chamber through the inlet 131; after the water enters the treatment chamber through the inlet 131, it rotates (vortexes), which is conducive to the water in the treatment chamber being discharged through the first outlet or the second outlet 122; in addition, increasing the speed of the impeller 51 is beneficial to improving the cleaning effect of the cleaning component 3;

[0077] The blades of the impeller 51 are oblique blades; specifically, the inlet 131 is located on one radial side of the impeller 51, the first outlet is located on the other radial side of the impeller 51, and the second outlet 122 is located at one axial end of the impeller 51; along the axis of the impeller 51 toward the second outlet 122, the blades of the impeller 51 are inclined relative to the axis of the impeller 51; so that the impeller 51 can both provide power for water to flow from the inlet 131 to the first outlet and provide power for water to flow from the inlet 131 to the second outlet 122.

[0078] The structure of the filter screen 21 is directly related to the filtration area of ​​the filter screen 21. In this embodiment, the filter screen 21 is cylindrical, which can increase the water flow rate of the filter screen 21 and the filtration area of ​​the filter screen 21, and can effectively isolate the hair in the water; one end of the cleaning component 3 is coaxially connected to the impeller 51, and the other end of the cleaning component 3 is set on the outside of the filter screen 21 or extends into the inside of the filter screen 21.

[0079] Driven by the impeller 51, the cleaning component 3 rotates and cleans the filter screen 21; specifically, the cleaning component 3 scrapes the lint off the surface of the filter screen 21 when it rotates.

[0080] When the water in the treatment chamber is to be discharged through the second outlet 122, it must first be filtered by the filter screen 21. The structure of the filter screen 21 determines whether this part of the water can be filtered well. The structure of the filter screen 21 is further explained below. The filter screen 21 includes a first filter part 211, which is arranged in a cylindrical shape. The water in the treatment chamber can be filtered by the first filter part 211 before being discharged through the second outlet 122. The cleaning component 3 includes a first cleaning part 31, the extension direction of which is parallel to the axial direction of the first filter part 211. The first cleaning part 31 is in contact with the first filter part 211. When the first cleaning part 31 rotates, it can clean the first filter part 211. Specifically, the first filter part 211 and the impeller 51 are coaxially arranged.

[0081] The filter screen 21 includes a second filter section 212, which is circular. Water in the treatment chamber can be filtered by the second filter section 212 before being discharged from the second outlet 122. The cleaning component 3 includes a second cleaning section 32, the extension direction of which is parallel to the radial direction of the second filter section 212. The second cleaning section 32 is in contact with the second filter section 212. When the second cleaning section 32 rotates, it can clean the second filter section 212.

[0082] Whether the lint on the filter screen 21 can be cleaned in a timely and thorough manner depends on the structure of the cleaning component 3. The structure of the cleaning component 3 will be further explained below. Multiple first cleaning parts 31 are provided, which surround the outside of the first filter part 211 and are spaced apart along the circumference of the first filter part 211. The structure formed by the multiple first cleaning parts 31 is coaxially arranged with the first filter part 211, and each first cleaning part 31 is interference-fitted with the first filter part 211. When the multiple first cleaning parts 31 rotate with the impeller 51, they can scrape the lint on the first filter part 211 to achieve a self-cleaning effect.

[0083] Multiple second cleaning sections 32 are provided, which surround the second filter section 212 on the side near the impeller 51 and are spaced apart circumferentially along the second filter section 212. The structure formed by the multiple second cleaning sections 32 is coaxially arranged with the second filter section 212, and each second cleaning section 32 is interference-fitted with the second filter section 212. When the multiple second cleaning sections 32 rotate with the impeller 51, they can scrape the lint on the second filter section 212 to achieve a self-cleaning effect.

[0084] Furthermore, the first filter section 211 and the second filter section 212 are integrally formed; the cleaning component 3 also includes a cleaning frame 33, which is annular and is disposed between the impeller 51 and the filter screen 21; a first cleaning section 31 is provided at one end of the cleaning frame 33 near the filter screen 21, and a second cleaning section 32 is provided on the inner side of the cleaning frame 33; the radial inner ends of a plurality of second cleaning sections 32 are connected together.

[0085] The following further describes the structure required for the impeller 51 and the cleaning component 3 to rotate. An impeller shaft hole 511 is formed on the radial inner side of the impeller 51. The cleaning component 3 also includes a rotating shaft 34, which passes through the impeller shaft hole 511 and is connected to the impeller 51 in a driving connection. One end of the rotating shaft 34 is connected to the radial inner end of the second cleaning part 32.

[0086] The housing 1 also has a housing shaft hole, which communicates with the processing chamber; the filter self-cleaning mechanism also includes a drive motor 52, which is located outside the housing 1; the output shaft of the drive motor 52 passes through the housing shaft hole into the processing chamber and is driven and connected to the other end of the rotating shaft 34.

[0087] When the drive motor 52 is running, the rotating shaft 34 rotates, which drives the impeller 51 and the cleaning component 3 to rotate synchronously; thus achieving automatic cleaning of the filter screen and solving the problems of difficulty, time and labor costs, and negative impact on user experience when cleaning the filter screen manually.

[0088] The specific structure of the processing chamber is further described below. The processing chamber includes an inlet channel 13, a main discharge chamber 111, and a secondary discharge chamber 121. The inlet channel 13 and the main discharge chamber 111 are connected inside the housing 1, and the main discharge chamber 111 and the secondary discharge chamber 121 are connected inside the housing 1. An inlet 131 is formed at the end of the inlet channel 13 away from the main discharge chamber 111, and the flow area of ​​the inlet channel 13 gradually decreases from the inlet 131 towards the inside of the processing chamber. The first outlet is connected to the main discharge chamber 111, and the second outlet 122 is connected to the secondary discharge chamber 121.

[0089] Impeller 51 is disposed in main discharge chamber 111, and filter screen 21 and cleaning component 3 are disposed in secondary discharge chamber 121;

[0090] Specifically, the shell 1 includes an integrally formed main drainage shell 11 and a secondary drainage shell 12. The main drainage shell 11 is cylindrical, and its axis is arranged in the horizontal direction. The main drainage shell 11 forms a main discharge cavity 1111. One axial end of the main discharge cavity 1111 is closed, and the other axial end of the main discharge cavity 1111 forms a first outlet. The inlet channel 13 is cylindrical, and its axis is arranged in the horizontal direction. The axis of the inlet channel 13 is perpendicular to the axis of the main drainage shell 11. The secondary drainage shell 12 is cylindrical, and its axis is arranged in the vertical direction. The axis of the secondary drainage shell 12 is perpendicular to the axis of the main drainage shell 11. The secondary drainage shell 12 forms a secondary discharge cavity 1211.

[0091] When the filter screen 21 is installed in the discharge sub-cavity 121, it requires a certain support structure. The following describes the support structure required for the filter screen 21. The filter screen assembly 2 also includes a filter screen frame 22. The filter screen frame 22 includes a first support 221 and a second support 222. The first support 221 is fixedly installed in the discharge main cavity 111. The second support 222 is installed on the first support 221 and extends into the discharge sub-cavity 121. The first support 221 and the second support 222 are arranged to form an installation space, and the first support 221 forms a support shaft hole 223.

[0092] Both the impeller 51 and the cleaning component 3 are rotatably mounted in the installation space, and the rotating shaft 34 passes through the bracket shaft hole 223 and the housing shaft hole and is driven and connected to the output shaft of the drive motor 52; the filter screen 21 is supported on the filter screen frame 22 and is located in the installation space.

[0093] Water in the treatment chamber can only be discharged from the second outlet 122 after passing through the filter screen 21. The following is a further explanation of the required structure. The filter screen self-cleaning mechanism also includes a water passage shell 4. The water passage shell 4 is disposed in the discharge sub-chamber 121 and is connected to the end of the second support 222 away from the first support 221.

[0094] The interior of the water-passing shell 4 forms a water-passing cavity 411. At the end of the water-passing shell 4 near the filter screen 21, a water-passing cavity inlet 421 is formed, which connects the discharge sub-cavity 121 and the water-passing cavity 411. At the end of the water-passing shell 4 near the second outlet 122, a water-passing cavity outlet 412 is formed, which connects the water-passing cavity outlet 412 and the second outlet 122.

[0095] Water entering the secondary discharge chamber 121 from the main discharge chamber 111 is first filtered by the filter screen 21, then enters the water chamber 411 through the water chamber inlet 421, and is discharged through the water chamber outlet 412 and the second outlet 122.

[0096] Specifically, the water passage shell 4 includes a main water passage shell 41 and a bottom water passage shell 42. The main water passage shell 41 is cylindrical and forms a water passage cavity 411. One axial end of the main water passage shell 41 forms a water passage cavity outlet 412. The bottom water passage shell 42 is disposed at the other axial end of the main water passage shell 41 and forms a water passage cavity inlet 421. The bottom water passage shell 42 is connected to the second support 222.

[0097] To ensure that water in the treatment chamber is discharged from only one of the two outlets, the following further explains the self-cleaning mechanism of the filter screen, which also includes a first drain cover 61 and a second drain cover 63. The first drain cover 61 is located at the first outlet and has a first cover outlet 614. The first cover outlet 614 is connected to the first outlet, and a first valve is provided at the first cover outlet 614.

The axis of the first cover joint 613 is parallel to and spaced apart from the axis of the drainage main shell 11.

[0098] The second drain cover 63 is disposed at the second outlet 122. The second drain cover 63 forms a second cover outlet 636, which communicates with the second outlet 122. A second valve is disposed at the second cover outlet 636. The second valve can be controlled to open or close the second cover outlet 636. Specifically, the second drain cover 63 includes a second end cover 631, a second cylinder 632, a third cylinder 633, and a second cover connector 634. The second cylinder 632 is disposed on one side of the second end cover 631, and one axial end of the second cylinder 632 is connected to the second end cover 631.

[0100] When the first cover outlet 614 is closed and the second cover outlet 636 is open, the water in the treatment chamber can be filtered through the filter screen 21 and then discharged through the second outlet 122 and the second cover outlet 636.

[0101] Example 2

[0102] Based on Example 1, this example further proposes:

[0103] like Figure 7 As shown, this embodiment proposes a garment processing device, including an outer cylinder 71, an inner cylinder 72, a pipe connector 73, a drain pipe 74, a spray assembly, and a filter self-cleaning mechanism as described in any of the above. The outer cylinder 71 has an outer cylinder water outlet, and the outer cylinder water outlet and the water inlet 131 are connected through the pipe connector 73. The first water outlet is connected to the drain pipe 74, and the drain pipe 74 is used to directly discharge the water in the processing chamber. The pipe connector 73 is made of soft rubber. Specifically, the outer cylinder 71, the pipe connector 73, the shell 1, the first drain cover 61, and the drain pipe 74 form a drainage path, and the water in the outer cylinder 71 can be discharged through the drainage path.

[0104] The inner cylinder 72 is rotatably disposed inside the outer cylinder 71, and the inner cylinder 72 is used to hold clothes; the spray assembly includes a spray head and a spray pipe 75, and the spray head is disposed inside the inner cylinder 72; the spray head and the second water outlet 122 are connected through the spray pipe 75, and the spray head is used to spray water filtered by the filter screen 21 into the inner cylinder 72.

[0105] A drain pipe 74 is connected in series with a drain valve 62, and a spray pipe 75 is connected in series with a spray valve 64. By controlling the drain valve 62 and the spray valve 64, the water in the outer cylinder 71 can be directly discharged through the treatment chamber and the drain pipe 74, or sprayed into the inner cylinder 72 through the treatment chamber, the filter screen 21, the spray pipe 75 and the spray head. Specifically, the outer cylinder 71, the pipe joint 73, the shell 1, the second drain cover 63, the spray pipe 75 and the spray head form a spray flow path, and the water in the outer cylinder 71 can be sprayed into the clothes in the inner cylinder 72 through the spray flow path.

[0106] In summary, the filter self-cleaning mechanism can realize the functions of drainage, spray washing and cleaning filter 21. It can replace the drain pump required for drainage and the high-pressure pump required for spray washing in clothing processing equipment. It has a compact structure, simplifies the structure of clothing processing equipment, and solves the problem of many parts and difficult layout in clothing processing equipment.

[0107] When the impeller 51 rotates, the water in the outer cylinder 71 can enter the treatment chamber through the inlet 131. The water in the treatment chamber can be directly discharged through the first outlet and the drain pipe 74, which can discharge the water in the outer cylinder 71 in a timely manner; or the water in the treatment chamber can be filtered through the filter screen 21 and then sprayed out through the second outlet 122, the spray pipe 75 and the spray head. The water in the outer cylinder 71 can be recycled and used for spraying and washing clothes, ensuring the spray flow rate and spray effect, improving the washing ratio of clothes and avoiding the waste of water resources. From the inlet 131 to the inside of the treatment chamber, the flow area of ​​the inlet 131 gradually decreases, and as the impeller 51 rotates, the water in the treatment chamber rotates, which increases the water pressure and achieves a better circulating spray effect.

[0108] As the cleaning component 3 rotates with the impeller 51, it automatically cleans the lint on the filter screen 21, ensuring timely and thorough cleaning, increasing the flow rate of the spray water, guaranteeing the spraying effect, and preventing filter screen clogging.

[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 has a washing program, and when the garment processing device runs the washing program, the control method includes:

[0110] Determine whether the garment processing equipment needs to operate the spray washing function;

[0111] When the garment processing equipment needs to operate the spray washing, the drain valve 62 is closed and the spray valve 64 is opened, and the impeller 51 is rotated. Water in the outer drum 71 can enter the processing chamber through the inlet 131. The water in the processing chamber is first filtered by the filter screen 21 and then sprayed onto the clothes in the inner drum through the second outlet 122, the spray pipe 75 and the spray head to spray and wash the clothes. The water flow path is: outer drum 71 → pipe joint 73 → processing chamber → filter screen 21 → second outlet 122 → second cover joint 634 → spray pipe 75 → spray head → clothes in the inner drum 72. When the cleaning component 3 rotates with the impeller 51, it can clean the lint on the filter screen 21.

[0112] When the garment processing equipment does not require spray washing, the drain valve 62 is opened and the spray valve 64 is closed, controlling the impeller 51 to rotate. The impeller 51 can act as a drain pump, allowing water in the outer drum 71 to enter the processing chamber through the inlet 131. The impeller 51 causes the water to rotate rapidly, and due to centrifugal force, the water in the processing chamber is directly discharged through the first outlet and drain pipe 74, and lint detached from the filter screen 21 is also discharged with the water. The water flow path is: outer drum 71 → pipe joint 73 → processing chamber → first outlet. Outlet → First cover connector 613 → Drain pipe 74; During the washing process, the garment processing equipment will generate lint. In order to avoid lint clogging the spray device, the outer drum 71 drains water when the garment processing equipment does not need to run the spray washing; because the impeller 51 will quickly drive the cleaning component 3 coaxially connected to the impeller 51 to rotate under the drive motor 52, the cleaning component 3 quickly scrapes the lint on the filter screen 21, causing the lint on the surface of the filter screen 21 to fall off and be discharged from the outer drum 71 with the water, thus achieving a self-cleaning effect.

[0113] Further optimization is possible:

[0114] Impeller 51 is an inclined impeller. Under the impact of water flow at inlet 131, impeller 51 can rotate on its own. Drive motor 52 and shaft 34 are equipped with a clutch mechanism, which can be used to control the connection and disconnection of drive motor 52 and shaft 34. When filter screen 21 is severely clogged, in order to avoid overloading drive motor 52, the clutch mechanism can be controlled to disconnect drive motor 52 and shaft 34, so that impeller 51 rotates completely under the action of water flow, forming a negative pressure on inlet 131, thereby facilitating the rapid inflow and discharge of sewage.

[0115] Furthermore, the drain valve 62 can be controlled to open and close according to preset rules. For example, when the filter screen 21 is severely clogged and the drainage is poor, the drain valve 62 can be controlled to open and close intermittently at a certain rhythm to create an agitation effect on the water in the treatment chamber, so that more dirt can be shaken away with the water flow.
