The fully automatic washing machine controls the water inlet, the drainage and the on/off of the motor through the water level switch and the electromagnetic water inlet valve: thus achieving automatic control. The electromagnetic inlet valve acts as a source of water. When the electromagnetic coil is de-energized, the moving iron core is tightly placed on the rubber diaphragm under the action of gravity and spring force, and the central hole of the diaphragm is blocked, so that the valve is closed and the water flow is blocked. When the electromagnetic coil is energized, the moving iron core moves up under the action of the magnetic force, leaves the diaphragm, and the central hole of the diaphragm opens, so that the water above the diaphragm flows into the washing tub through the central small hole. Since the flow capacity of the central small hole is greater than the flow capacity of the small holes on both sides of the diaphragm, the pressure above the diaphragm is rapidly reduced, the diaphragm will move up under the action of the pressure difference, the closed door is opened, and the water flow is conducted.
