Drum washing machine

Abstract

The invention provides a drum washing machine which comprises an inner drum, wherein the inner drum is a non-porous inner drum, and contains washing water during clothes washing. The drum washing machine also comprises an air pressure balancing mechanism used for communicating the inner drum with external environment so as to balance the air pressure in the inner drum. The invention provides the drum washing machine which has the non-porous inner drum and is of a front opening structure. The structure is simple. Washing / rinsing water does not need to be filled between the inner drum and an outer drum, so that the washing water consumption of the washing machine is greatly reduced. The drum washing machine has the advantages that during water inlet, air in a sealed cabin of the inner drum is pressed, and can overflow through the air pressure balancing mechanism to ensure the air pressure balance. When the water failure suddenly occurs, external air can fast enter the sealed cabin of theinner drum, the suck-back condition is damaged, the air pressure balance is ensured, and the washing water is prevented from being sucked into a tap water pipe network.

Description

technical field [0001] The invention relates to the technical field of laundry equipment, in particular to 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 drum washing machine. There is a door seal between t...

AI Technical Summary

Problems solved by technology

Because clothes must be soaked in a certain amount of washing water, if you want to achieve the effect of soaking, you need to store a certain amount of water in the non-porous inner cylinder, which will increase the burden on the motor and cause problems such as power consumption.

In addition, the water intake method of the drum washing machine disclosed in this patent is through the door seal. Since the main function of the door seal is to realize the sealing of the drum mouth of the outer cylinder of the washing machine, setting the water inlet conduit on the door seal will easily affect the sealing effect of the door seal, and it is not easy Realized, and this patent cannot realize the detection of the water level in the inner cylinder

[0005] In addition, the present invention mainly solves the problem of how to ensure the unbalanced air pressure in the airtight compartment of the non-porous inner drum washing machine. Specifically, the sudden solenoid valve cut off water, especially the tap water pipe network, forms a negative pressure and drains the washing water in the airtight cabin. Backwashing to the pipe network; or there is gas inside and it is difficult to enter water
