Title:
WASHING MACHINE AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/164529
Kind Code:
A1
Abstract:
The present invention relates to a washing machine including an actively movable balancer, and a control method thereof. The washing machine according to an embodiment of the present includes: a tub; a drum; a plurality of balancing units that move along a front or rear circumference of the drum in order to reduce the unbalance generated by the gathering of fabric to one side during the rotation of the drum; a vibration detecting sensor for detecting the vibration amount of the tub; and a control unit that moves the plurality of balancing units according to the vibration amount of the tub as measured by the vibration detecting sensor. The control unit may control a drum motor to move the plurality of balancing units in the same rotation direction so that the drum rotates at a constant rotation speed and the vibration amount of the tub as measured by the vibration detecting sensor is minimized, and then move the plurality of balancing units in different directions from each other so that the vibration amount of the tub as measured by the vibration detecting sensor is minimized, and thereby reduce unbalance.
