Background

With the development of economy, the living standard of people is gradually improved; the washing machine is also a household appliance necessary for families; at present, an inner barrel support and a rotating shaft used by a pollution-free pulsator washing machine are two independent parts which are mutually matched and arranged in the washing machine.

As shown in fig. 5 and 6, 1 ' is an inner barrel base, 2 ' is an inner barrel support, 3 ' is a fastening screw, 5 ' is a rotating shaft, and a support sealing ring 4 ' is arranged between the inner barrel support 2 ' and the rotating shaft 5 ' to prevent water from flowing out of the inner barrel support 2 ' and the rotating shaft 5 ' to cause water leakage. The above expression has the following disadvantages:

1. the installation efficiency is low, and the operation is inconvenient.

2. And a sealing element is required to be added between the rotating shaft and the support, so that the sealing performance of the sealing ring is reduced after the sealing ring is used for a long time, and the sealing ring is easy to age and lose efficacy.

3. The inner barrel support is fastened on the inner barrel base through fastening screws, the coaxiality consistency is low, the eccentric vibration of the washing machine is easy to cause, and the reliability is low.

Chinese patent document No. CN110331557A discloses an outer cylinder bottom of a washing machine in 2019, 6 and 14, and specifically discloses that the outer cylinder bottom of the washing machine comprises an outer cylinder bottom body and a shaft sleeve embedded in the outer cylinder bottom body; the shaft sleeve comprises a bearing installation chamber capable of being assembled with a bearing and at least one supporting body; the support body is arranged on the outer wall of the bearing installation chamber; the outer wall of the bearing installation chamber is provided with a support body. However, the support body and the bearing in the outer barrel bottom of the washing machine are easy to deform and crack after long-term use, potential safety hazards exist, once the support body and the bearing are damaged, the inner barrel support and the rotating shaft need to be integrally replaced, and therefore the washing machine is high in maintenance cost and short in service life.

Therefore, further improvements are desired.
