Title:
CENTRIFUGAL DRAINAGE MECHANISM AND LAUNDRY LIFTING DEVICE FOR WASHING MACHINE, AND WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/257997
Kind Code:
A1
Abstract:
A centrifugal drainage mechanism (5) and a laundry lifting device for a washing machine, and a washing machine. The centrifugal drainage mechanism (5) comprises: a centrifugal component (51), which moves under the action of a centrifugal force; a valve plug component (52), which is used for sealing a drainage hole of a washing machine in a normal condition; and a lever structure (53), wherein the middle of the lever structure is rotatably supported and fixed, one end of the lever structure is connected and fixed to the centrifugal component (51), and the other end of the lever structure abuts against the valve plug component (52) and is in contact fit with the valve plug component (52). The centrifugal component (51) presses an end, which matches the valve plug component (52), of the lever structure (53) to rotate to a direction away from the valve plug component (52) under the action of the centrifugal force, and then the valve plug component (52) moves to open the drainage hole. The lever structure (53) of the centrifugal drainage mechanism (5) is only in contact fit with the valve plug component (52), thereby effectively solving the problems whereby the valve plug component (52) is subjected to a cornering force of a tensile force of a lever (53) because an existing lever structure (53) is hinged and connected to a valve plug (52) by means of a shaft and a shaft hole, and thus, the position of the valve plug (52) does not preferably correspond to that of the drainage hole, the valve plug (52) fails, and a sealing effect of an inner cylinder (1) is affected.
