Washing machine and balancer

Abstract

The invention provides a washing machine and a balancer. The washing machine includes an annular ball balancer in a washing tub about a vertical axis. The ball balancer includes a plurality of balls, a viscous fluid, a balancer case having an annular ring space defined therein, the ring space being partitioned into a bottom surface, top surface, inner circumferential surface, and outer circumferential surface, and a plurality of division plates to partition the ring space into a plurality of arc-shaped divided spaces. The viscous fluid and at least one of the balls are received in each divided space. Each divided space is provided at a portion thereof corresponding to the bottom surface with an inclined surface downwardly inclined from one end of each division plate to a deepest part in a circumferential direction. The deepest part of each divided space is located at a position where weight balance of the balls is achieved in a stop state.

Description

technical field

[0001] Embodiments of the present disclosure relate to a vertical fully automatic washing machine that continuously performs washing, rinsing, and spin-drying processes. Background technique

[0002] In such a fully automatic washing machine (hereinafter, simply referred to as a washing machine), a water tub is suspended in a housing, and a washing tub rotating around a vertical axis is installed in the water tub. Clothes are introduced into the washing tub, and a series of processes from washing to spinning are performed sequentially under automatic control. During spinning, the tub spins at high speed.

[0003] If the laundry gathers on one side of the washing tub during spinning, the washing tub and water tub vibrate a lot. As a result, the durability of the washing machine is reduced, and noise is generated from the washing machine. For this reason, a ring balancer is usually installed in the washing tub to dampen the vibration.
