Abstract
A drainage control mechanism comprises a valve plug capable of being stretchable and retractable, wherein the valve plug moves upwards to close the drainage port of an inner tub, and moves downwards to open the drainage port. A lower end of the valve plug is connected with a link of a crank-link structure, an idle stroke is arranged between the link and a crank, and/or between the link and the valve plug. When the valve plug sticks out but not into the drainage port, the valve plug will stick to the bottom of the inner tub, the driving motor drives the crank or the link to move in the idle stroke. When the driving motor drives to move over the highest point, the driving motor further drives the valve plug to move downwards to reset and to re-enter the next working circle.
