ABSTRACT:
A drum type washing machine includes a drum mounted in a water-receiving tub so as to be rotated about its transverse axis in a wash step, a brushless motor for rotating the drum, and a control device for controlling the motor. The rotational speed of the drum is controlled in the wash step so as to be varied in each period of its rotation in a range at least including a speed at which clothes accommodated in the drum are caused to fall down from the inner peripheral wall surface of the drum against centrifugal force.
