Document Type and Number:
WIPO Patent Application WO/2021/139518
Kind Code:
A1
Abstract:
Disclosed are a laundry lifting device for a washing machine, and a drum washing machine. A laundry lifting device (32) for a washing machine comprises: a lifting housing (3201) internally provided with an open cavity; a lifting base body (3208) covering an open end of the lifting housing (3201) to form an accommodating chamber; a water inflow filtering part, which is arranged on the lifting housing (3201) and/or the lifting base body (3208) and in communication with the accommodating chamber so as to filter inflowing water in the accommodating chamber; and a centrifugal drainage assembly, which is provided in the accommodating chamber, wherein the initial state of the centrifugal drainage assembly is a closed state, and the centrifugal drainage assembly can be opened for drainage under the action of centrifugal force. The accommodating chamber where the centrifugal drainage assembly is located becomes an area independent of the interior of an inner cylinder (17), the area maintains communication with the inner cylinder (17) by means of the water inflow filtering part and can effectively filter lint, such that the centrifugal drainage assembly is located in an environment without lint or with very little lint, thereby fundamentally avoiding the possibility of lint attachment, and effectively ensuring the operation reliability of the centrifugal drainage assembly.
