WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/001181
Kind Code:
A1
Abstract:
A washing machine capable of increasing the dehydration rate by rotating a dehydration tub at a high speed during dehydration. The washing machine comprises: a dehydration tub, a pulsator being provided at the bottom of the dehydration tub; three or more baffles provided at equal intervals in a circumferential direction on an inner circumferential surface of the dehydration tub; a water injection device capable of independently injecting and adjusting water into each baffle; an acceleration detection unit for detecting the vibration of the dehydration tub; a dehydration tub position detection device for sending pulse signals corresponding to the rotation of the dehydration tub; an eccentric detection unit for detecting the eccentric amount and the eccentric position in the dehydration tub; a water injection control unit for controlling the water injection device to inject water into the baffles corresponding to the eccentric position when the eccentric amount in the dehydration process reaches a specified eccentric amount threshold for water injection; a maximum rotation speed determination unit for determining the maximum rotation speed in the dehydration process on the basis of the water injection state into the three or more baffles; and a motor control unit for controlling a motor for rotationally driving the dehydration tub in the dehydration process.
