Detailed ways

The drainage effect of the related drainage device is poor, and some small-sized foreign matter can easily enter the floor drain through the filter and the drainage pipe of the drainage device, causing blockage of the drainage pipe and the floor drain. In addition, the washing water may contain dirt or dust in addition to coins or crumbs, and after the washing water is discharged, debris, mud, dust, and the like in the washing water may accumulate in the filter. Since the filter of the washing machine drain device is cleaned every once in a while, foreign matter accumulates in the filter for a long time, which will generate odor and breed bacteria; and the water inlet of the drain device is connected with the outer tube, and bacteria and odor are easily accessible. In the outer cylinder, secondary pollution is caused, which affects the washing effect and the health of the user.

The present embodiment provides a schematic diagram of a filter for a washing machine, FIG. 1 is a schematic structural view of a filter of the drain device of the present embodiment, FIG. 2 is a schematic structural view of a filter core provided by the present embodiment, and FIG. 3 is a schematic view of the present embodiment.
