Abstract
A drum type washing machine capable of realizing weight reduction and improvement in washing performance at low cost is provided. A drum type washing machine is disclosed. A pulsator is installed rotatably at a bottom of the drum rotatably accommodated in a tub. A motor configured to rotate forward and backward rotationally drives the drum and the pulsator. A control device executes a washing mode in which the motor is driven at a low rotation and a spinning mode in which the motor is driven at a high rotation. The pulsator and the drum have different velocity ratios. A second drive transmission element of the pulsator includes a clutch. Based on executing the washing mode, the drum is rotationally driven while the pulsator is rotationally driven or is allowed to idle. Based on executing the spinning mode, the drum is rotationally driven while the pulsator is allowed to idle.
