Description

Defoaming structure of drum washing machine

Technical Field

The utility model belongs to the technical field of drum washing machines, and particularly relates to a defoaming structure of a drum washing machine.

Background

The existing washing mode is mainly characterized in that detergents such as laundry detergent, washing powder and soap are combined with water to generate foam when clothes are washed, and oil stains are taken away to achieve a washing effect. In the consumer recognition, more foam and cleaner washing are needed, so that the consumer can put in excessive detergent when using the washing machine, and a large amount of air bubbles are generated between the inner drum and the outer drum when the drum washing machine works.

Excessive foaming causes the following problems:

1. excessive foam can cause the pressure in the drum to rise, the rotating friction force of the inner drum is increased, the motor is overloaded, the motor is blocked and overheated for a long time, and the temperature rise performance of a washing machine product is influenced.

2. Excessive foam can cause a barrel internal pressure to rise, and because of the main water inlet mode of the drum washing machine flows in by gravity, the excessive pressure in the barrel can lead to the reduction of the water inlet efficiency by natural gravity, and water can not enter under extreme conditions, even the foam flows backward, and overflows from a water inlet box.

3. Excessive foam influences the washing of clothing, and when the urceolus was full of the foam, the washing efficiency was fully reduced to the contact of clothing and water, and the clothing has reduced the dynamics of beating because of the buffering of foam when beating simultaneously to influence the washing performance, influence and prolong the washing time even.

4. Excessive foam influences drainage performance, and after the foam is produced, the foam can be attached to clothes and a barrel, and the foam can not be discharged along with water during drainage, still can become foam water after standing or spraying defoaming, causes the phenomenon that foam still exists on discharged water and the clothes after rinsing for many times, lets the consumer think that the washing ability of machine itself has the problem.

Excessive foam residue can cause allergy to partial people, and the residue in the washing machine is mainly glass bowl and door seal ring, so that bacteria and even peculiar smell are easy to breed after long-term storage.
