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.

Drainage control mechanism of inner tub and washing machine

A control method of a water-saving washing machine and washing machine, of which a locking hole and a drainage port are formed in a bottom of an inner tub, and a locking mechanism and a drainage control mechanism are arranged at the bottom of an outer tub, comprising: Step I: carrying out a washing/rinsing procedure, a master control board controlling the locking mechanism to couple with the locking hole to lock the inner tub, and the drainage control mechanism blocking off the drainage port, supplying water to the inner tub, starting washing; Step II: carrying out a drainage procedure, the master control board controlling the drainage control mechanism to open the drainage port, water in the inner tub being drained; Step III: carrying out a dewatering procedure, the master control board controlling the locking mechanism to release the inner tub to drive the inner barrel to rotate for dehydration.

Control method of a water-saving washing machine and washing machine

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.

Locking mechanism for inner tub and washing machine

A control method for automatically positioning an inner tub. When the inner tub rotates to a certain position, a positioning pin at the bottom of an outer tub is released to press against the bottom of the inner tub, the inner tub continues to rotate, and when a positioning hole at the bottom of the inner tub is aligned with the positioning pin, the positioning pin stretches into the positioning hole, and thus the inner tub is locked. After the positioning pin is released, the inner tub continues to rotate under the effect of inertia, or the inner tub continues to rotate under the drive of a motor, when the inner tub rotates to the position where the positioning hole is aligned with the positioning pin, the positioning pin stretches into the positioning hole to achieve automatic positioning and locking of the inner tub.
