Abstract: The present invention relates to a washing machine which includes a cylindrical part having a cylindrical shape and at least one balancer installed in the cylindrical part. The balancer includes a first balancer housing provided with a race in an annular shape with an open top and a second balancer housing to be coupled with the first balancer housing to cover the open top of the race. The balancer is installed in the cylindrical part in such a way that a coupling portion of the first balancer housing and the second balancer housing corresponding to an inner circumferential surface of the cylindrical part is covered by the cylindrical part, thereby reinforcing a strength of the balancer by the cylindrical part.

Abstract: A washing machine having a ball balancer to reduce vibration generated during dehydrating process and a vibration controlling method thereof are disclosed. In a washing machine having a ball balancer, a dehydrating process starts while residual water having a preset water level remains in the tub without draining water completely when entering the dehydrating process, and the quantity of residual water is set differently according to eccentricity so that excessive vibrations of a tub may be reduced using the weight of the residual water while passing through a resonant point. Speed of a motor is maintained at a preset speed lower than the resonant point for a preset time to release balls in the ball balancer so that excessive vibrations of the tub generated by concentrated balls and unbalanced laundry may be surely reduced. After passing through the resonant point, the residual water is drained to reduce drain noise and to prevent delay of dehydrating time.

Abstract: A washing apparatus including an AC motor configured to generate a rotating force, a clutch unit configured to selectively transmit the rotating force to a rotating tub and a pulsator, a speed detector configured to detect a rotating speed of at least one of the AC motor and the clutch unit, and a controller configured to repeat power supply and power cut-off to the AC motor according to the rotating speed. The washing apparatus can control the power supply and power cut-off to the AC motor based on the rotating speed.

Abstract: 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.
