WASHING MACHINE
Document Type and Number:
Japanese Patent JP2021137177
Kind Code:
A
Abstract:
To enable a position where an unbalance state of a rotary tub occurs to be determined, when the unbalance state occurs.SOLUTION: A washing machine according to the embodiment comprises: a water tub elastically supported in a body by an elastic support mechanism; a rotary tub arranged rotatably in the water tub; a drive mechanism including a motor for rotating the rotary tub; a control device controlling a washing operation; an acceleration sensor provided at the water tub, and detecting acceleration caused by the oscillation of the water tub regarding a plurality of axial directions; and an unbalance detection unit detecting an unbalance state of the rotary tub from the detection value of the acceleration sensor. The unbalance detection unit acquires a displacement amount in each axial direction of the water tub from the detection value of the acceleration sensor, and determines an unbalance position of the rotary tub based on the ratio between the acquired displacement amounts.SELECTED DRAWING: Figure 1
