Title:
WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/179268
Kind Code:
A1
Abstract:
A washing machine, comprising: a drum (200) for holding laundry; a drum support (300), which is arranged in the washing machine in such a way that same can rotate around a shaft, and which is used for placing the drum (200); and a centrifugal lock member (1), which is mounted on the drum (200) and is configured to radially extend out to be inserted into the drum support (300) under the action of a centrifugal force when the rotation speed of the drum (200) exceeds a set value. By means of such configurations, when the rotation speed of the drum (200) of the washing machine is relatively high, the centrifugal locking member (1) automatically extends out, so that the drum (200) and the drum support (300) are relatively locked in an axial direction when the washing machine executes a program such as water removal at a relatively high rotation speed. Moreover, the centrifugal locking member (1) is correspondingly controlled by using the centrifugal force generated by the rotation speed of the drum, which not only saves costs, but also improves control precision.
