The water inlet 11 and the circulating water outlet 12 may be provided on the side walls of the housing 1, respectively, and the water inlet 11 is disposed opposite to the circulating water outlet 12. For example, referring to fig. 2 and 3, the water inlet 11 may be provided on the left side wall of the housing 1, the circulating water outlet 12 may be provided on the right side wall of the housing 1, and the water inlet 11 may be disposed opposite to the circulating water outlet 12. Thus, the washing circulating water in the inner tub is facilitated to flow from the water inlet 11 to the circulating water outlet 12 and to flow to the inner tub through the circulating water outlet 12, so as to wash the laundry in the inner tub or the washing machine 1000 itself.

Alternatively, the water inlet 11 may be formed in the form of a section of water inlet pipe, thereby facilitating the communication of the water inlet 11 with the inner cylinder, and having a simple structure and convenient installation.

The drain port 13 may be provided at one axial end (e.g., the rear end in fig. 4) of the housing 1. Thereby, the washing water in the inner tub is conveniently discharged from the drain port 13 to the outside of the washing machine 1000.

As shown in fig. 4, the filter device 2 includes a filter body 21, an arc-shaped filter member 22 is provided on the filter body 21, the arc-shaped filter member 22 extends from the water inlet 11 toward the water outlet 13, and the arc-shaped filter member 22 is located between the water inlet 11 and the circulating water outlet 12 in the water flow direction. Specifically, referring to fig. 4 to 6, the arc-shaped filter 22 may be formed as an arc-shaped surface that is arc-shaped transitionally from the front end of the filter body 21 toward the rear end of the filter body 21 and protrudes toward the circulating water outlet 12, the water inlet 11 and the circulating water outlet 12 may be located at both sides of the arc-shaped filter 22, respectively, and the water inlet 11 and the water outlet 13 may be located at the same side of the arc-shaped filter 22. For example, referring to fig. 3, the water inlet 11 and the water outlet 13 may be disposed at the left side of the arc-shaped filter 22, and the circulating water outlet 12 may be disposed at the right side of the arc-shaped filter 22.

Specifically, the drain pump assembly 4 includes a drain pump 41 and a drain motor 42, an inlet of the drain pump 41 communicates with the drain port 13, and an outlet of the drain pump 41 may be connected with a drain pipe of the washing machine 1000. The drain motor 42 is connected to the drain pump 41 to drive the drain pump 41 to drain the washed waste water to the outside of the machine body 1001.

For example, in the washing machine 1000, the water inlet 11 of the drain assembly 100 communicates with the drum during washing of laundry, and the inside of the drain assembly 100 is filled with water and does not flow in the case that neither the circulation pump 31 nor the drain pump 41 is operated. When the door window 1002 and other parts of the washing machine 1000 need to be cleaned, the circulating pump 31 starts to work under the drive of the circulating motor 32, washing circulating water in the inner cylinder flows into the drainage assembly 100 from the water inlet 11 under the action of pressure, enters the circulating water outlet 12 after being filtered by the arc-shaped filter 22 on the filter device 2, and then flows back to the inner cylinder under the action of the circulating pump 31. Accordingly, impurities such as filth in the washing circulating water can be filtered out through the arc-shaped filter 22 and remain on the surface of the arc-shaped filter 22, so that filth in the washing water can be effectively filtered, and the washing effect of the washing machine 1000 can be improved.

Thus, the self-cleaning function of the drain assembly 100 can be achieved by the washing wastewater carrying away the flock collected on the surface of the arc-shaped filter 22.

Specifically, one end (e.g., the front end in fig. 3) of the arc-shaped filter 22 extends to be connected to the water inlet 11. Therefore, the washing circulating water in the inner barrel can be guaranteed to flow back to the inner barrel after being filtered by the arc-shaped filter piece 22, so that burrs and the like in the washing circulating water are gathered on the surface of the arc-shaped filter piece 22, the burrs are prevented from remaining in a gap between the water inlet 11 and the arc-shaped filter piece 22, the burrs can be prevented from blocking a filtering channel between the water inlet 11 and the circulating water outlet 12, the burrs can be guaranteed to be discharged out of the washing machine 1000 along with the washing wastewater, and the filtering effect and the self-cleaning capability of the drainage assembly 100 are improved.

According to the drainage assembly 100 for the washing machine 1000 of the embodiment of the invention, by arranging the arc-shaped filter piece 22 on the filter device 2 and enabling one end of the arc-shaped filter piece 22 to extend to be connected with the water inlet 11, washing circulating water in the inner cylinder can be guaranteed to flow back to the inner cylinder after being filtered by the arc-shaped filter piece 22, and filings and the like in the washing circulating water are collected on the surface of the arc-shaped filter piece 22, so that filings are prevented from being remained in a gap between the water inlet 11 and the arc-shaped filter piece 22, a filtering channel between the water inlet 11 and the circulating water outlet 12 can be prevented from being blocked by the filings, and filings can be guaranteed to be discharged outside the washing machine 1000 along with washing wastewater, and the filtering effect and self-cleaning capability of the drainage assembly 100 are improved.

According to some embodiments of the present invention, the arcuate filter 22 is an arcuate filter screen. Wherein, the mesh number of the arc-shaped filter screen is 30-50 meshes, for example, 35 meshes, 40 meshes, 45 meshes, 50 meshes and the like can be adopted. Therefore, when the washing circulating water passes through the arc-shaped filter screen, substances such as filth and the like in the washing circulating water can be filtered cleanly, and the arc-shaped filter screen can be prevented from being blocked by the substances such as filth and the like, so that the washing circulating water can smoothly flow through the arc-shaped filter screen to enter the circulating water outlet 12, the requirement of no filth of the washing circulating water can be met, the cleaning of the circulating water is ensured, the influence on the performance of the circulating pump assembly 3 is avoided, and the normal work of the circulating pump 31 is ensured.
