Abstract (en)
A washing machine (1) which determines an unbalanced state of laundry (3) using an unbalance value and a variation of the unbalance value according to time so as to reduce the generation of vibration and noise, and a method for detecting the unbalanced state of the laundry (3) therein. The washing machine (1) includes a rotary tub (2) containing laundry (3), a washing motor (45) for rotating the rotary tub (2), a motor speed detecting unit (46) detecting the speed of the washing motor (45) and outputting a motor speed signal, and a controller (42) calculating an unbalance value of the laundry (3) and a variation of the unbalance value using the motor speed signal, determining the unbalanced state of the laundry (3) in the rotary tub (2) using the unbalance value and the variation of the unbalance value, and controlling the washing motor (45) according to determination results.
