Abstract
A locking mechanism of an inner tub comprises a locking rod and a driving unit for moving the locking rod in an axial direction. A lower end of the locking rod is connected with a link of a crank-link structure, and an idle stroke is arranged between the link and a crank and/or between the link and the locking rod. A locking hole is formed in the bottom of the inner tub. When the locking rod sticks out but not into the locking hole, the locking rod sticks 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 locking rod to move downwards to reset and to re-enter the next working circle.
