Abstract
A sealing valve plug structure includes a valve plug column corresponding to the drain opening formed in the side wall of an inner drum, and a counterweight hinged to the upper end of the valve plug column. The sealing valve installation structure is installed on the side wall of the drum, and the reset spring is clamped between the sealing valve installation structure and the valve plug column. The counterweight is used to generate an action, under the action of centrifugal force, to open the drain opening, and the valve plug column is reset by the reset spring to make the valve plug block the drain opening, to thereby open and close the drain opening. A cleaning-free washing machine having an inner drum sealed by the sealing valve plug structure is also disclosed.
