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.

Abstract: A washing machine includes an outer barrel and an inner barrel rotatably arranged in the outer barrel. During the washing/rinsing process, the inner barrel contains water, and there is no water between the inner barrel and the outer barrel. A drainage hole is arranged on the bottom of the inner barrel. A drain-sealing device and a driving device are arranged on a bottom of the inner barrel. The drain-sealing device comprises a sealing part cooperating with the drainage hole to control the opening/closing of the drainage hole, and a connecting part connected with the driving device. During washing/rinsing, the sealing part of the drain-sealing device keeps the drainage hole closed. During draining/dehydrating, the drain-sealing device opens the drainage hole under the action of the driving device. The drain-sealing device and the driving device are installed on the inner barrel, and rotate with the the inner barrel during dehydrating.

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.

Abstract: 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.

Abstract: A locking mechanism for an inner tub comprises a locking rod capable of reciprocating along an axial direction, and a driving unit for driving the locking rod to move; and the locking mechanism further comprises a position switch with a triggering structure arranged on the locking rod. A locking hole is formed in the bottom of the inner tub of the washing machine; after the locking rod sticks into the locking hole and is locked in place, the triggering structure triggers the position switch, and the position switch sends out a locked-in-place signal; and after the locking rod retracts from the locking hole and is subjected to retracting resetting, the triggering structure triggers the position switch, an unlocked-in-place signal is sent out, and thus, a master control board of the washing machine can control the washing machine to perform a procedure of the next step.

Abstract: The present disclosure relates to a locking mechanism of an inner tub and a washing machine. The locking mechanism comprises a locking rod capable of reciprocating along an axial direction, a slideway for the movement of the locking rod and a driving unit for driving the locking rod to move, the driving unit comprises a link, a crank and a rotating motor; wherein, a bearing is mounted between the locking rod and the slideway. The bearing which mounted between the locking rod and the slideway, is to reduce the friction between the locking rod and the slideway, and to prevent the locking rod from moving unsmooth that caused by got stuck from the slideway. When the crank rotates to 90° or 270°, and the friction between the locking rod and the slideway is maximum, the locking rod is ensured to move smooth.

Abstract: A washing machine comprises at least two sets of washing devices and a display control panel, wherein the display control panel includes at least two different independent display interfaces, with one display interface corresponding to one set of washing device. The display control panel of the washing machine can display at least two colors, with one display interface corresponding to one color. After the washing machine is initialized, one set of the washing device or the combination of the at least two sets of washing devices are arbitrarily selected, and the display interfaces corresponding to different control processes of the selected washing device display different brightness. Through arranging at least two colors on the display screen of the washing machine, different control processes of the washing machine can be realized through the switching between different colors and different brightness, thereby satisfying the individual requirements of more users.
