The invention provides a drum extrusion type washing machine improved based on a conventional washing machine, and through change of the washing mode, the washing capability is obviously improved, theabrasion rate is reduced, and the energy consumption is reduced. The drum extrusion type washing machine comprises a housing, a damping device, a water-containing tub, a dehydration tub, an extrusiondevice, an electric control device, a water supply and drainage device, and a driving device. Four corners of the housing are connected to the water-containing tub through the damping device, the dehydration tub is arranged in the water-containing tub, an inner wall of the dehydration tub is provided with two movable extrusion plates, the extrusion plates are rectangular meshed plates bent in a certain radian, the extrusion plates are folded during washing, the extrusion plates isolate the dehydration tub into two independent spaces, clothes can rotate in the water with the dehydration tub and extruded during rotation, the clothes roll over and absorb water when rotation is stopped, and extrusion washing of the clothes can be realized in a circulated and repeated manner. During drying, the two extrusion plates are attached to the inner wall of the dehydration tub under the effect of a centrifugal force due to the special shape of the extrusion plates, and centrifugal dehydration and drying of the clothes are not influenced.
