Abstract
A drum type washing machine includes a cabinet, a fixed drum set in the cabinet to contain wash water therein, a rotary drum rotatably set inside the fixed drum, a pump which forcibly pumps out the wash water contained in the fixed drum, and a water circulation device which feeds the wash water pumped by the pump into the rotary drum in a washing operation. The water circulation device includes a storing unit and a spraying unit. The storing unit defines a space which temporarily holds the wash water pumped by the pump, and is provided between rear panels of the fixed drum and the rotary drum. The storing unit guides the wash water to the rear panel of the rotary drum. The spraying unit is provided at the rear panel of the rotary drum, and sprays the wash water contained in the storing unit into the rotary drum.
