PROBLEM TO BE SOLVED: To avoid prolonging of dewatering time by suppressing vibration of a drum to be small without increasing transmission of the vibration to a floor even when an uneven distribution degree of laundry is large.SOLUTION: A drum type washing machine includes: an outer case; a water tub disposed in the outer case while being supported in a vibration-proof manner by a vibration-proof device; a drum disposed inside the water tub; a liquid-sealed type rotary balancer provided in the drum; a motor for rotating the drum; and control means for controlling the motor. With the control means, an angular acceleration of the drum is decreased in a rotational speed region including a rotational speed region K in which the water tub generates resonance and including a region L vertically near the region K.SELECTED DRAWING: Figure 1 |
