PURPOSE: A full automatic washing machine is provided to simplify the structure of a clutch and to secure strong rotational force required for washing and high rotative velocity required for dehydrating. CONSTITUTION: A full automatic washing machine with an outer rotor-type BLDC(Brushless Direct Current) motor includes an outer tub installed in an outer case constituting the external form of the washing machine; a washing tub rotatably installed inside the outer 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(300) covering the dehydrating shaft; a stator assembly(400) producing a rotative magnetic field; a rotor assembly(500) forming a magnetic path and comprising a rotor frame, magnets, and a washing shaft-combining part; a clutch assembly(600) including a sliding coupler(650) controlling power transmission and a control unit to control 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 to control 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 and then rotating the rotor assembly to rotate only the washing blades. The full automatic washing machine executes washing by combining a mutual reverse rotation mode 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 and the brake assembly is released from the dehydrating shaft by completely releasing the brake pad from a drum(160) and operating the water discharge valve. |
