Description
Technical Field
The invention belongs to the technical field of washing, and particularly provides a pulsator washing machine with a self-cleaning device.
Background
In order to facilitate the life of people and effectively improve the life quality of people, more and more types of washing equipment are continuously emerged on the market to help people wash clothes. In recent years, with the increasing number of washing equipment, people have made higher and higher demands on the comprehensive performance of the washing equipment. Taking the cleaning performance of the washing machine as an example, in order to guarantee the washing effect of the existing washing machine to the maximum extent, users often require the washing machine to have a self-cleaning function, so as to effectively guarantee the cleaning degree of the washing machine, and thus effectively avoid the problem that the washing effect of the washing machine is not good due to the fact that the interior of the washing machine is not clean. In order to make the washing machine have a self-cleaning function, the existing washing machine is usually provided with a self-cleaning device between an inner barrel and an outer barrel so as to clean two parts, namely the outer wall of the inner barrel and the inner wall of the outer barrel, which need to be cleaned most; however, for the pulsator washing machine, cleaning is also needed between the bottom of the pulsator and the bottom of the inner tub, and the existing washing machine does not provide any cleaning scheme for the problem.
Further, even if the scheme of cleaning the inner and outer barrels is applied to the cleaning impeller, the existing cleaning scheme still has many problems. The existing part of washing machines realize self-cleaning by arranging a cleaning brush on one of the outer wall of an inner barrel and the inner wall of an outer barrel, but the cleaning mode can only realize self-cleaning on one of the outer wall of the inner barrel and the inner wall of the outer barrel, but cannot realize comprehensive cleaning of the outer wall of the inner barrel and the inner wall of the outer barrel, and the cleaning scheme is applied to the cleaning of the bottom of a wave wheel and the inner wall of the inner barrel, and cannot realize comprehensive cleaning of the two parts simultaneously; meanwhile, in some existing washing machines, self-cleaning is achieved by arranging a plurality of cleaning balls between the outer wall of an inner barrel and the inner wall of the outer barrel, the cleaning mode seems to be capable of achieving comprehensive self-cleaning, however, when the inner barrel rotates, the cleaning balls are always gathered to the upper portion of the washing machine under the action of buoyancy, so that the cleaning mode cannot achieve comprehensive self-cleaning at all, when the inner barrel does not rotate, the cleaning balls can be gathered near a driving shaft of the washing machine, dirt is easily gathered near the driving shaft, and the cleaning scheme is applied to cleaning the bottom of a wave wheel and the inner wall of the inner barrel, and similarly, the comprehensive self-cleaning effect cannot be achieved well. Therefore, the self-cleaning scheme of the existing washing machine can not only not clean the bottom of the impeller, but also is difficult to realize the comprehensive self-cleaning effect.
Accordingly, there is a need in the art for a new pulsator washing machine having a self-cleaning apparatus to solve the above problems.

Further, it should be noted that, although the centrifugal assembly 22 described in the present preferred embodiment is composed of the rotating member 221, the fixed member 222, the moving member 223, and the elastic member 224; however, it is obvious that the centrifugal assembly 22 may also comprise only the rotation member 221, in which case the end of the rotation member 221 remote from the centrifugal member 2211 may be directly connected to the cleaning member 20.

When the driving shaft 15 is rotated at a high speed, the centrifugal member 2211 can be rotated to the left and downward by the centrifugal force, so that the moving member 223 is pulled to press the elastic member 224 to be deformed and moved upward, and the moving member 223 pulls the connecting chain 225 upward to pull the chain body 201 taut, thereby bringing the cleaning member 20 out of contact with the bottom of the inner tub 13. It can be understood by those skilled in the art that the length of each component and the weight of the centrifugal component 2211 can be set by those skilled in the art according to the actual use requirement, so that the centrifugal component 2211 can rotate only when the driving shaft 15 reaches the preset rotation speed.
So far, the technical solutions of the present invention have been described with reference to the accompanying drawings, but it is obvious to those skilled in the art that the scope of the present invention is not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
