WASHING MACHINE AND CONTROL METHOD THEREOF

摘要

A washing machine which improves performance of balancers, and a control method thereof. The washing machine includes a drum accommodating laundry and rotated by rotary force transmitted from a drive source, balancer housings mounted on the drum, each of the balancer housings including a disc-shaped channel formed therein, balancing modules movably disposed in the channels of the balancer housings, vibration sensors to sense unbalance applied to the drum during rotation of the drum, position sensors to sense the positions of the balancing modules, and a controller controlling movement of the balancing modules to positions to compensate for the unbalance sensed by the vibration sensors.

1. A control method of a washing machine, which includes a drum, balancer housings mounted on the drum, and balancing modules movably disposed in the balancer housings, comprising:
rotating the drum; detecting a vibration value of a tub of the washing machine, when the RPM of the drum has reached a first RPM; detecting a position of unbalance applied to the drum and positions of the balancing modules within the balancer housings, when the detected vibration value of the tub is more than a predetermined reference value; determining positions of the balancing modules to compensate for the unbalance applied to the drum; and controlling the balancing modules to move to the determined positions.
