Abstract: Disclosed herein is a drum type washing machine capable of obtaining a high-water saving effect. The drum type washing machine comprises at least one processor configured to control a drive device configured to rotate a drum, a water supplier configured to supply water to a tub, and a sprinkler configured to spray water stored in the tub toward laundry accommodated in the drum. The drum comprises a lifter and a plurality of rear through-holes. The at least one processor is configured to perform a water spray process while rotating the drum in a state in which an amount of wash water absorbable by the laundry is maintained in the tub, in a washing cycle. In the water spray process, a waiting process, in which driving a circulation pump 91 is stopped, is intermittently and repeatedly performed.

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.
