Elastic suspending portions (3) allowing accommodation tub (2) to be suspended from the upper side of cabinet (5) allow accommodation tub (2) to be suspended from symmetrical positions with respect to a rotation axis of drum (1). Vibration detecting unit (11) detecting a vibration of accommodation tub (2) detects a vibration of accommodation tub (2) in the front/rear direction. Rotation speed control unit (13) changes a rotation speed of motor (6) in accordance with the magnitude of the frequency component calculated by frequency component calculating unit (12) with respect to the vibration in the front/rear direction. Accordingly, the fabric state may be highly precisely detected, and the rotation speed of drum (1) may be controlled. As a result, the cleaning performance of the washing machine may be improved. |
