PROBLEM TO BE SOLVED: To provide a drum type washing machine which allows control for suppressing vibration by decreasing a rise degree of a rotational speed of a drum to be selected by a user's manual operation.SOLUTION: A drum type washing machine of the embodiment includes: an outer case; a water tub supported inside the outer case by a vibration-proof device; a drum disposed inside the water tub; a liquid-sealed type rotation balancer provided in the drum; a motor for rotating the drum; control means for controlling the motor; and an operation part operated by a manual operation. In the case where the operation part is operated by a manual operation, the control means performs angular acceleration decreasing control of the drum for decreasing angular acceleration in a rotational speed region in vertical vicinity including a rotational speed region where the water tub generates resonance.SELECTED DRAWING: Figure 4 |
