Laundry treatment apparatus

Abstract

A laundry treatment apparatus including a rotatable drum in which laundry is stored, at least three balancers mounted to the drum so as to be spaced apart from one another by the same angle around a rotation center of the drum. Liquid is introduced into and discharged from the balancers via a feeder supplying the liquid and a flow path structure mounted to the drum to guide liquid supplied from the feeder to the balancer located in a direction for removal of unbalance of the drum.

Description

technical field [0001] The present disclosure relates to a laundry treating device. Background technique [0002] A conventional laundry treating apparatus includes a cabinet that defines the appearance of the device, a tub installed in the cabinet, a drum rotatably installed in the tub so that laundry is washed in the drum, and a motor. The motor includes a rotation shaft penetrating the tub and coupled with the drum to rotate the drum. [0003] Since the location of laundry stored in the drum may cause unintentional rotation of the drum, the drum may not be able to maintain dynamic balance. [0004] Dynamic equilibrium refers to a state of a rotating body in which the centrifugal force or the moment of the centrifugal force becomes zero with respect to the axis of rotation of the rotating body. In the case of a rigid body, dynamic equilibrium is maintained by a constant mass distribution about the axis of rotation. [0005] Therefore, for a laundry treatment device, dyn...

Problems solved by technology

[0011] Although the above-mentioned unbalance control method is usable in a stable state where the vibration of the drum falls within a given range, a large difference in the transient state (that is, in the transient vibration state) cannot be expected until the vibration of the drum reaches a stable state. influences

[0012] In addition, it is difficult for conventional balancing units to actively eliminate imbalances as soon as they occur
