AI Technical Summary

Technical Problem

The lack of water passage holes on the inner drum sidewall of existing pulsator washing machines makes it difficult to exchange liquid between the inner and outer drums, hindering the realization of functions such as water heating and drying inside the drum, and the drainage structure is also complex.

Method used

A water-air channel is designed to form a reusable channel for liquid circulation, drainage, hot air delivery, and pressure transmission through the cooperation of the bottom connection port of the inner cylinder, the sealing structure, and the water box, so as to achieve stable connection between the inner cylinder and the external functional modules.

Benefits of technology

Without increasing structural complexity, a multi-functional pulsator washing machine with a water-passing hole-free inner drum sidewall structure has been achieved, improving washing performance, water-saving performance, and simplifying the drainage and hot air drying processes.

Abstract

This invention relates to a pulsator washing machine with a water-air channel, comprising an outer drum, an inner drum disposed within the outer drum, a water tank, a sealing structure, and a blower. The bottom of the inner drum has a first connecting port. The sealing structure is disposed between the bottom of the outer drum and the bottom of the inner drum, forming a sealing fit with both the outer and inner drums. The sealing structure also has a second connecting port corresponding to the position of the first connecting port. The water tank is disposed outside the inner drum and includes a reusable port, which communicates with the inner drum via the first and second connecting ports. The first, second, and reusable ports together constitute the water-air channel, which is configured to perform at least two functions—liquid circulation, drainage, hot air delivery, and pressure transmission—under different operating conditions of the washing machine. Embodiments of this invention facilitate a compact overall layout and cost optimization.
