Automatic positioning inner barrel control method

Abstract

The invention relates to an automatic positioning inner barrel control method; the bottom of the inner barrel is provided with a positioning hole; the bottom of the outer barrel is provided with a positioning pin; the positioning pin is provided with a structure driving the positioning pin to telescope; when the inner barrel rotates to certain position, the positioning pin is released to press the bottom of the inner barrel; the inner barrel continuously rotate until the positioning hole aligns with the positioning pin, the positioning pin can extend into the positioning hole so as to lock the inner barrel. After the positioning pin is released, the inner barrel continuously rotate under inertia effect, or the inner barrel is driven by a motor to continuous rotate; when the inner barrel rotates and the positioning hole aims at the positioning pin, the positioning pin can extend into the positioning hole, thus automatically positioning and locking the inner barrel; a water outlet and a draining control structure can be ensured to be sealed, thus preventing water leakage.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a control method for automatically positioning an inner tub. Background technique [0002] In the existing pulsator washing machine, there are water permeable holes in the inner barrel, and the inner and outer barrels are connected. The inner barrel is a washing barrel, and the outer barrel is a water bucket. The water that participates in washing is only the part in the inner tub, which leads to greater waste of water resources. In addition, too much water between the inner and outer tubs will also reduce the concentration of detergent / washing powder in the washing liquid. At the same time, due to the frequent flow of water in and out between the inner barrel and the outer barrel, after continuous use, the area between the side walls of the inner barrel and the outer barrel has also become a space for dirt. The cellulose of clothes, the organic matter of the human body and the d...

Problems solved by technology

But long-term operation, because the sealing structure is worn for a long time, it is easy to cause wear and leakage. If the water quality is poor and the sand content is high, the service life will be greatly shortened, and it will not be able to perform its due function.

It is also not suitable for use in the state of large washing capacity, and the reliability is poor
