PURPOSE: A full-automatic washing machine is provided to prevent the washing machine from lengthening and the eccentricity of a washing tub, to increase power output of a motor by directly connecting an outer rotor-type motor to the lower side of a clutch, and to improve washing efficiency by performing an agitation mode for rotating only a pulsator and rotating reverse the pulsator and the washing tub. CONSTITUTION: A full-automatic washing machine is composed of an outer tub mounted in an out case forming the external shape; a washing tub rotatably installed in the outer tub; a pulsator rotatably arranged in the inner lower side of the washing tub; a dewatering shaft(100) for rotating the washing tub; a washing shaft(200) combined with the pulsator; a clutch housing for covering the dewatering shaft; a stator assembly(400) for generating rotational magnetic field; a rotor assembly(500) for inducing electric currents and generating rotary power; a clutch assembly(600) having a sliding coupler(650) for controlling power transmission with sliding along the dewatering and washing shafts and a control unit for controlling movements of the sliding coupler; a protrusion(652) formed on the upside of the sliding coupler and selectively connected to a combining hole(660b) arranged at a stopper(660) of the clutch assembly; a drain valve for controlling water in the outer tub; a gear motor used for controlling a drive unit and a drain unit, connecting and operating the drain valve and a brake lever, and operating the brake lever to first and second gear ranges; and a brake assembly(700) having a brake pad(780) and the brake lever for braking the rotation of the dewatering shaft. The full-automatic washing machine performs a washing process by combining an agitation mode and a washing tub-rotation mode. |
