Abstract: A compact washing machine capable of improving detergency or reducing a washing time is provided. A drum 30 may be rotatably installed in a tub 20 installed in the inside of a housing 10 in the state in which an opening 12 is toward an opening of the drum 30. A pulsator 40 having a protrusion 45 extending in a radial direction may be rotatably installed on a bottom of the drum 30. During washing operation, a controller 60 may control a driving device 50 to rotate the pulsator 40 and the drum 30 in opposite directions.

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.
