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

Embodiment Construction

[0036] Such as figure 1 As shown, the washing machine in the present invention includes an inner tub 100 and an outer tub 200. The inner tub body 101 has no leaking holes communicating with the outer tub. The bottom of the inner tub 102 is provided with a drainage port 105, and the top of the inner tub body 101 is provided with a circle of drainage holes 106. When washing, the drain port 105 is closed, the water level is lower than the height of the drain hole 106, there is only water in the inner tub 100, and there is no water between the inner tub 100 and the outer tub 200. After washing, the drain port 105 is opened, and most of the water comes from the drain When dehydrating, the inner bucket 100 rotates, and the water released from the clothes rises along the wall of the bucket under the action of centrifugal force, and is discharged from the inner bucket through the drainage hole 106 on the upper part of the inner bucket to between the inner and outer buckets, and then pa...

Abstract

The invention relates to a locking mechanism of an inner tub and a washing machine. The locking mechanism includes a locking lever capable of reciprocating axial movement, a slideway for the locking lever to move, and a drive unit for driving the locking lever to move. The driving unit includes a connecting rod, a crank and a rotating motor, and is characterized in that a bearing is arranged between the locking rod and the slideway. A bearing is arranged between the locking rod and the slideway to reduce the frictional force between the locking rod and the slideway, so as to avoid the blockage of the locking rod caused by the slideway. Ensure that the crank rotates to 90° or 270°, and when the friction force between the locking lever and the slideway is the largest, the locking lever moves smoothly.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a locking mechanism for an inner tub and a washing machine. Background technique [0002] In the existing pulsator type washing machine, there is a permeable hole in the inner barrel, and the inner and outer barrels are connected. 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 dust and bacteria brought in by the clothes are very likely to stay between the s...
