Description

Washing machine

Technical Field

The invention belongs to the field of household appliances, and particularly relates to a washing machine.

Background

As shown in fig. 1, the structure of the conventional washing machine generally includes two parts, i.e., an inner tub 1 'and an outer tub 2', wherein the inner tub 1 'and the outer tub 2' are communicated, the inner tub 1 'is provided with a dehydration opening for dehydration, and the outer tub 2' is closed as a water tub. Therefore, when the washing machine works, the area between the inner barrel 1 'and the outer barrel 2' is full of water, and in the long-time use and operation process of the washing machine, the area between the inner barrel 1 'and the outer barrel 2' can be covered fully by dirt and thread scraps in water, bacteria and peculiar smell can be generated in the use of the washing machine for a long time, and the washing effect and the user experience are greatly influenced.

In addition, the wave wheel 3 ' and the inner barrel bottom 4 ' of the existing full-automatic wave wheel washing machine are driven by different driving shafts, and the wave wheel 3 ' can rotate relative to the inner barrel bottom 4 ', so a gap exists between the wave wheel 3 ' and the inner barrel bottom 4 ', and the bottom of the wave wheel 3 ' generally has more reinforcing ribs, so that the problem of dirt storage and scale accumulation between the wave wheel 3 ' and the inner barrel bottom 4 ' is easy to occur along with the increase of the service time of the washing machine, and finally, the secondary pollution of the washed clothes is caused.

In order to solve the problem of secondary pollution caused by the fact that water is filled between an inner barrel and an outer barrel to wash clothes, the prior manufacturers research and develop a novel washing machine, the inner barrel can be sealed, and no water exists between the inner barrel and the outer barrel so as to avoid the problem of pollution. The known solution is to design the inner barrel as a non-porous inner barrel, so as to isolate the inner barrel from the outer barrel, the inner barrel serves as a water containing barrel, and in order to realize the drainage of the inner barrel, the centrifugal force generated by the rotation of the inner barrel driven by relatively high rotation speed is utilized to make the water in the inner barrel throw out from the dewatering opening at the upper end of the inner barrel, or the water is supported on the drainage opening at the bottom of the inner barrel through an external sealing structure, so as to realize the sealing of the inner barrel. Although the inner barrel without holes can solve the problem of dirt between the inner barrel and the outer barrel, the problem of dirt between the impeller and the bottom of the inner barrel cannot be solved.

Therefore, the invention mainly aims to solve the problem of dirt accumulation between the impeller and the barrel bottom of the inner barrel of the full-automatic impeller washing machine, and further, the invention realizes the comprehensive self-cleaning of the washing machine by combining the self-cleaning scheme of the inner barrel without holes, thereby avoiding the dead corners of dirt accumulation. However, in the washing machine with such a structure, the motor directly drives the whole inner barrel component and the washings in the inner barrel to run together with the water during washing, so that the acceleration is fast, and the momentum of the lifted inner barrel component and the washings and water in the inner barrel is large. According to the law of acting force and reacting force, the reacting amount formed by the outer barrel part is also larger. The existing damping device can not solve the problem that the outer barrel part moves obviously in the washing machine box body to impact the box body, thereby causing abnormal noise.

In view of the above, the present invention is particularly proposed.
