Clothes lifting device for washing machine and roller washing machine

Abstract

The invention provides a clothes lifting device for a washing machine and the roller washing machine. The clothes lifting device for the washing machine comprises a body which is internally provided with a containing cavity, a water inlet formed in the body and communicating with the containing cavity, and a centrifugal drainage assembly arranged in the containing cavity, wherein the initial state of the centrifugal drainage assembly is a closed state, and the centrifugal drainage assembly can be opened for drainage under the action of centrifugal force; the centrifugal drainage assembly comprises a sealing plunger capable of doing reciprocating motion and an elastic piece used for elastic resetting of the sealing plunger; the body is provided with a plunger base used for installing the sealing plunger; the sealing plunger is arranged in the plunger base in a reciprocating motion mode; and the sealing plunger and the plunger base are each provided with a limiting structure used for abutting against and limiting the elastic piece. According to the centrifugal drainage assembly, the limiting structures are arranged on the sealing plunger and the plunger base in a matched mode through the elastic piece, so that the sealing plunger can be elastically abutted, and the sealing plunger is kept in a normally-closed state.

Description

technical field [0001] The invention relates to the technical field of laundry equipment, in particular to a laundry lifting device for a washing machine and a drum washing machine. Background technique [0002] As the most widely used household appliance in people's daily life, washing machine helps people to get rid of the troubles of laundry and brings great convenience to people. But the washing machine also has certain disadvantages, such as long time-consuming, large water consumption, etc. With the development of society, water resources, as an important natural resource, become more and more important, and people's water-saving awareness is also increasing. Therefore, how to realize the water-saving function of the washing machine is particularly important. [0003] In order to solve the water-saving problem of the washing machine, some patents have also been proposed now, such as the patent number 201410215346.3, which is named as a Chinese invention patent of a dr...

AI Technical Summary

Problems solved by technology

[0004] The above invention provides a drum washing machine with a non-porous inner cylinder. The water intake method of the drum washing machine disclosed in this patent is through the door seal. Setting the water inlet pipe will easily affect the sealing effect of the door seal, and it is not easy to realize; in addition, the drainage of this patent is mainly realized through the cylindrical structure combined with the high-speed drive of the driving device. The cylindrical structure is complicated, and the drainage effect and the sealing effect of the inner cylinder cannot be guaranteed. , there will be many problems in practical application

[0005] In addition, how to solve the drainage of the drum washing machine during the washing process and the drainage problem during the dehydration process is a major problem faced by the non-porous inner cylinder. The existing application number is CN201710320239.0, which is called a Chinese drum washing machine The application for a patent for invention discloses in the description that "it includes an outer cylinder, the front end of which is fixed on the inner wall of the machine body, the inner cylinder is rotatably arranged in the outer cylinder, and a centrifugal valve is arranged on the side wall of the inner cylinder; when washing , the centrifugal valve is closed, the inner cylinder contains water, and there is no water between the inner cylinder and the outer cylinder. When dehydrating, the centrifugal valve is opened, and the washing water is discharged from the centrifugal valve to the space between the inner cylinder and the outer cylinder and then discharged from the outer cylinder." The patent proposes the use of centrifugal valves for centrifugal drainage to solve the drainage problem of non-porous drum washing machines. However, since lint will inevitably be generated during the washing process, preventing lint from entering the centrifugal valve with the water flow is to ensure the normal operation of the centrifugal valve. In particular, the centrifugal valve needs to be kept closed during the washing and rinsing stages of the drum washing machine, and its structure generally contains a spring. Once the lint is entangled on the spring, it is not only difficult to remove, but also seriously affects the normal work of the spring, causing The centrifugal valve is not closed properly, so that the water-saving and self-cleaning effect of the non-porous inner cylinder cannot be realized
