PURPOSE: A full automatic washing machine is provided to simplify the structure of a clutch and to obtain strong rotational force necessary for washing and high rotative velocity necessary for dehydrating. CONSTITUTION: A full automatic washing machine with an outer rotor-type induction motor comprises an outer tub installed inside an outer case constituting the exterior of the washing machine; a washing tub combined with a dehydrating tub; washing blades rotatably installed at the inner bottom of the washing tub; a dehydrating shaft(100) rotating the washing tub; a washing shaft(200) combined with the washing blades; a clutch housing covering the dehydrating shaft; a stator assembly(400) producing a rotative magnetic field; a rotor assembly(500) inducing a current and producing rotational force; a clutch assembly(600) including a sliding coupler(650) controlling power transmission and a control unit controlling movement of the sliding coupler; a water discharge valve controlling the washing water in the outer tub; a gear motor for drive device control and water discharge device control interlocking and operating the water discharge valve and a brake lever, and controlling the action of the brake lever in a first stage state and a second stage state; and a brake assembly(700) comprising the brake lever and a brake pad(780). In the full automatic washing machine, an agitating mode executes washing by restricting the dehydrating shaft by the brake pad and then rotating the rotor assembly surrounding the stator assembly and rotating just the washing blades. A combining mode executes washing or rinsing by combining permeating/pressing modes of executing washing by rotating the washing blades and the washing tub at the same speed and in the same direction in a state where the water discharge valve is not operated after releasing the brake pad from the dehydrating shaft. In a dehydrating stroke, the dehydrating shaft and the washing shaft are integrally rotated by completely releasing the brake pad from a drum(160) and operating the water discharge valve. |
