Description

An outer barrel structure with a filter cleaning mechanism

Technical field:

The utility model relates to the field of accessories for washing machines, in particular to an outer tub structure with a filtering and cleaning mechanism.

Background technique:

In existing washing machines, the inner wall structure of the outer tub is mostly smooth. During operation, it exchanges with the water flow brought by the rotation of the inner tub. During continuous cleaning, the dirt will also enter the space between the outer tub and the inner tub along with the water flow. Because there is no filter device on the inner wall of the outer barrel in the existing structure, the dirt will re-enter the inner barrel with the water flow. In this reciprocating operation, the dirt cannot be filtered in time, thus affecting the cleanliness and efficiency of cleaning, and the dirt Frequent exchanges between the inner barrel and the outer barrel are easy to stick to the clothes, especially the floating hair of some clothes fibers, which cannot meet the requirements of clean cleaning, so it needs to be improved.

Utility model content:

The purpose of the utility model is to make up for the defects of the prior art, to provide an outer barrel structure with a filter cleaning mechanism, which increases the filtering performance, ensures the cleaning efficiency and cleanliness, and at the same time adds a corresponding cleaning device, which can automatically clean The filter plate should be cleaned at the right time.

The utility model is achieved through the following technical solutions:

An outer barrel structure with a filtering and cleaning mechanism, comprising an outer barrel barrel, characterized in that: the inner wall of the outer barrel barrel is distributed with filter screen plates arranged along the axial direction and at intervals, and the filter screen plates are The rear side is provided with an elastic top plate matched with it, and the upper end of the filter cavity formed between the screen plate and the elastic top plate is provided with a cleaning pipe axially arranged and extending into the filter cavity, the cleaning pipe is close to the outer barrel The inner wall of the barrel is distributed with spray heads facing the screen plate, the upper end of the cleaning pipe is connected by an annular header, the annular header is located between the outer barrel and the inner barrel, and the water inlet pipe on the annular header passes through the branch pipe It is connected to the water inlet pipeline of the washing machine, and the branch pipeline is provided with a control valve and a booster pump.

The inner wall of the outer barrel is distributed with convex ribs arranged at intervals along the axial direction, one side of the convex ribs is distributed with a filter screen plate correspondingly arranged on one side, and one side of the screen plate is provided with a screen plate. The flanging is folded outward, and the flanging is fixed and installed on the convex edge by screws, and the other side of the screen plate is provided with a hook folded inward.

One side of the elastic top plate is hinged on the fixing ear on the inner wall of the outer barrel, the other side of the elastic top plate is fastened with the hook, and the rear end surface of the elastic top plate is connected with a spring, and the spring is located on the filter screen. In the cavity between the plate and the elastic top plate, and the other end is inclined and fixed on the inner wall of the outer barrel.

The inner side of the elastic top plate is provided with a shaft sleeve that is cooperatively connected with the fixing ears, the shaft sleeves are matched with the fixing ears, and the middle part is installed through the rotating shaft.

The cleaning pipe extends into the upper half of the filter cavity, and the spray heads are distributed from top to bottom from dense to sparse.

Its working principle is: through the structural design of the filter screen distributed on the inner wall of the outer tub, the dirt brought by the water flow can be filtered and collected. Since the motor rotates forward and reverse when the washing machine is working, therefore, in the filter screen. An elastic top plate is set behind the plate to make it meet the purpose of filtering and collecting in one direction; after filtering, the filter plate also needs to be cleaned in time, and the cleaning process can be through the branch pipe on it during each washing and draining process. After being pressurized by the booster pump, it is sprayed from the nozzle. The nozzle can spray off the dirt on the filter screen, and then drain together with the drainage. During the process, the water in and out is controlled by the control valve. When there is water flowing from the front end, it turns over to the inner wall of the outer bucket due to the action of the water flow, and the water flow is continuously filtered through the screen plate. The hook cooperates with the limit, and the water flow cannot remove the dirt and insects on the filter screen, so that the dirt accumulates in the space between the filter screen plate and the elastic top plate to achieve the purpose of completely removing the dirt. The overall structure design of the present application is reasonable. The filter performance is increased, the cleaning efficiency and cleanliness are ensured, and the corresponding cleaning device is added, which can clean the filter screen at a suitable time by itself, reducing the process of replacement and disassembly, and meeting the use requirements.

The advantages of the present utility model are:

The utility model has a reasonable structure design, increases the filtering performance, ensures the cleaning efficiency and cleanliness, and at the same time adds a corresponding cleaning device, which can automatically clean the filter screen plate at a suitable time, reduces the process of replacement and disassembly, and satisfies the usage requirements.
