Abstract
Provided is a drum washing machine. The drum washing machine, which is provided with a rotating body on the rear a drum, is able to smoothly switch between a first form in which the drum and the rotating body rotate independently and a second form in which the drum and the rotating body rotate integrally. When switching from a biaxial driving form to a uniaxial driving form and vice versa, a control part rotates a rotor clockwise and anticlockwise in a manner of taking a reverse actionand a reverse actionduring the operation of a torque motor, i.e., during an action of moving a clutch body by virtue of a moving mechanism. The reverse actionincludes an action of stopping the rotor rotating clockwise direction, and the reverse actionincludes an action of stopping the rotor rotating anticlockwise.
