Abstract

A drum-type washing machine including at least one lifter for supplying wash water from the outside of a drum to the inside of the drum, and a controller for controlling water supply operations and washing operations based on the angle of rotation of the drum sensed by an angle sensing device. The controller positions the lifter under a water supply pipe so that the wash water is directly supplied from the outside of the drum to the inside of the drum through the lifter. Thus, laundry loaded in the drum is uniformly and rapidly wetted with the wash water. The controller also causes the laundry carried by the lifter to fall from the top position of the drum to maximize dropping power in a wash mode.
