Abstract
A drum type washing machine includes a cabinet which defines an outer appearance of the washing machine, a water tub set inside the cabinet to contain wash water therein, a rotary tub having spin drying perforations and rotatably set in the water tub, and a water turbine which is mounted at an open front of the rotary tub and rotates along with the rotary tub to spray the wash water contained in the water tub into the rotary tub. The water turbine includes an external member having an annular shape, and an internal member having an annular shape corresponding to the external member. The internal member is arranged apart from the external member by a predetermined interval. A vane unit is set between the external and the internal members, and raises the wash water contained in the water tub and sprays the wash water into the rotary tub.
