During the rotation process, the inner wall of the filter sleeve 32 is scraped by the scraper 33 constrained on the filter plate 12, and the residue on the side wall of the filter sleeve 32 is cleaned again. At the same time, the damping member 5 generates damping on the door body 2, so that the door body 2 is slowly closed;

[0046] When the washing program is run again, the scraped filter cover 32 maintains a high water return efficiency.

[0047] The present embodiment utilizes the hinge 4 and the damping member 5 on the side of the door body 2 to form a structure that can scrape and clean the inner wall of the filter sleeve 32 of the slag collecting basket 3 when the door is opened and closed. During the door opening process, the filter sleeve 32 is driven to rotate as the damping member 5 moves, thereby achieving a primary scraping and cleaning of the side wall of the filter sleeve 32. During the door closing process, the filter sleeve 32 is driven to rotate in the opposite direction as the damping member 5 returns to its original position, thereby achieving a secondary scraping and cleaning of the side wall of the filter sleeve 32. The double reverse scraping can effectively clean the slag collecting basket 3, thereby maintaining a high return water efficiency and avoiding clogging. In addition, the rotating structure of the filter sleeve 32 of the present invention is simple and reasonable, and is easy to produce and manufacture.
