Abstract
A drum type washing machine includes a water tub; a cylindrical rotary drum rotatably installed in the water tub such that a central axis of rotation of the rotary drum is horizontal or slanted; a water outlet provided on a bottom portion of the water tub; a motor for rotating the rotary drum; a water supplying unit for supplying wash water into the water tub; a water draining unit for draining the wash water from the water tub; and a controller for controlling the motor, the water supplying unit and the water draining unit to thereby perform a washing, a rinsing and a water-extracting process. A guiding member with a guiding surface is installed on an inner bottom portion of the water tub to facilitate collection of the wash water and guide the collected wash water toward the water outlet during the water-extracting process.
