[0101] Example 2

[0102] On the basis of Example 1, this example further proposes:

[0103] like Figure 7 As shown, this embodiment provides a clothes processing device, including an outer cylinder 71, an inner cylinder 72, a pipe joint 73, a drain pipe 74, a spray assembly and any one of the above filter self-cleaning mechanisms; the outer cylinder 71 is formed with an outer cylinder water outlet, and the outer cylinder water outlet and the water inlet 131 are connected through the pipe joint 73; the first water outlet is connected with the drain pipe 74, and the drain pipe 74 is used to directly discharge the water in the processing chamber; the pipe joint 73 is made of soft rubber; specifically, the outer cylinder 71, the pipe joint 73, the housing 1, the first drain cover 61 and the drain pipe 74 form a drainage flow path, and the water in the outer cylinder 71 can be discharged through the drainage flow path;

[0104] The inner drum 72 is rotatably disposed in the outer drum 71, and the inner drum 72 is used to place clothes; the spray assembly includes a spray head and a spray pipe 75, and the spray head is disposed in the inner drum 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 21 into the inner drum 72;

[0105] The drain pipe 74 is connected in series with the drain valve 62, and the spray pipe 75 is connected in series with the spray valve 64; by controlling the drain valve 62 and the spray valve 64, the water in the outer drum 71 can be directly discharged through the treatment chamber and the drain pipe 74, or sprayed into the inner drum 72 through the treatment chamber, the filter 21, the spray pipe 75 and the spray head; specifically, the outer drum 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 drum 71 can be sprayed onto the clothes in the inner drum 72 through the spray flow path.

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

[0107] When the impeller 51 rotates, the water in the outer cylinder 71 can enter the processing chamber through the water inlet 131, and the water in the processing chamber can be directly discharged from the first water outlet and the drain pipe 74, so that the water in the outer cylinder 71 can be discharged in time; or the water in the processing chamber is first filtered by the filter 21 and then sprayed out from the second water outlet 122, the spray pipe 75 and the spray head, so that the water in the outer cylinder 71 can be recycled and used for spraying and washing clothes, thereby ensuring the spray flow rate and spray effect, improving the clothing washing ratio, and avoiding the waste of water resources; from the water inlet 131 to the inner side of the processing chamber, the flow area of ​​the water inlet 131 gradually decreases, and as the impeller 51 rotates, the water in the processing chamber rotates to increase the water pressure, so as to achieve a better circulation spraying effect;

[0108] When the cleaning member 3 rotates with the impeller 51, the hair on the filter screen 21 is automatically cleaned, the cleaning is timely and thorough, the flow rate of the spray water is increased, the spray effect is guaranteed, and the filter screen is prevented from being blocked.

[0109] This embodiment also 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 washing program, and when the clothes processing device runs the washing program, the control method includes:

[0110] Determine whether the clothing treatment equipment needs to run spray washing;

[0111] When the clothing treatment device needs to perform spray washing, the drain valve 62 is controlled to be closed and the spray valve 64 is controlled to be opened, and the impeller 51 is controlled to rotate; the water in the outer cylinder 71 can enter the treatment chamber through the water inlet 131, and the water in the treatment chamber is first filtered by the filter 21 and then sprayed to the clothes in the inner cylinder through the second water outlet 122, the spray pipe 75 and the spray head, so as to spray wash the clothes; the water flow path is the outer cylinder 71→the pipe joint 73→the treatment chamber→the filter 21→the second water outlet 122→the second cover joint 634→the spray pipe 75→the spray head→the clothes in the inner cylinder 72; when the cleaning member 3 rotates with the impeller 51, the hair scraps on the filter 21 can be cleaned;

[0112] When the clothes treatment device does not need to run spray washing, the drain valve 62 is controlled to be opened and the spray valve 64 is closed, and the impeller 51 is controlled to rotate; the impeller 51 can act as a drainage pump, and the water in the outer cylinder 71 can enter the treatment chamber through the water inlet 131. The impeller 51 causes the water to rotate rapidly. Due to the effect of centrifugal force, the water in the treatment chamber is directly discharged from the first water outlet and the drain pipe 74, and the hair scraps shed from the filter 21 are discharged with the water; the water flow path is the outer cylinder 71 → the pipe joint 73 → the treatment chamber → the first water outlet Mouth → first cover joint 613 → drain pipe 74; during the washing process of the clothing processing device, hair debris will be generated. In order to prevent the hair debris from clogging the spray device, when the clothing processing device does not need to run the spray washing, the outer drum 71 is drained; because the impeller 51 is driven by the driving motor 52, it will quickly drive the cleaning member 3 coaxially connected to the impeller 51 to rotate, and the cleaning member 3 will quickly scrape the hair debris on the filter screen 21, so that the hair debris on the surface of the filter screen 21 falls off and is discharged from the outer drum 71 along with the water, so as to achieve a self-cleaning effect.

[0113] Further preferred options include:

[0114] The impeller 51 is an inclined impeller, which can rotate automatically under the impact of water flow at the water inlet 131. The drive motor 52 and the rotating shaft 34 are provided with a clutch mechanism, which can be used to control the connection and disconnection of the drive motor 52 and the rotating shaft 34; when the filter 21 is seriously dirty and blocked, in order to avoid overloading the drive motor 52, the clutch mechanism can be controlled to disconnect the drive motor 52 and the rotating shaft 34, so that the impeller 51 can rotate completely under the action of the water flow, forming a negative pressure effect on the water inlet 131, thereby facilitating the rapid inflow and discharge of the stored sewage.

[0115] It is further preferred that the drain valve 62 can be controlled to switch according to preset rules. For example, when the filter 21 is seriously dirty and blocked, the drain valve 62 can be controlled to switch on and off intermittently with a certain opening and stopping rhythm to achieve a stirring effect on the water in the processing chamber, so that more dirt can be discharged with the oscillation of the water flow.

[0116] The exemplary embodiments of the present disclosure are specifically shown and described above. It should be understood that the present disclosure is not limited to the detailed structures, configurations or implementations described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent configurations included in the spirit and scope of the appended claims.
