Description

Drainage filtering device of laundry equipment

Technical Field

The invention relates to a drainage filtering device of laundry equipment.

Background

Washing machines are cleaning appliances that wash laundry using mechanical action of electricity generation, and are classified into two categories, a household category and a collection category, according to their rated washing capacities.

The domestic washing machine is mainly composed of box body, washing dewatering drum (some washing and dewatering drums are separated), transmission and control system, and heating device. Washing machines are generally exclusively intended to use water as the main washing liquid, as opposed to the use of a specially prepared cleaning solution, and dry cleaning, which is usually carried out by a person skilled in the art.

The household washing machine has two drainage modes, one mode is natural drainage through gravity, and the drainage mode cannot effectively drain water in a cabin of the washing machine. Secondly, a pumping mode is adopted, and residual water in the washing machine can be effectively pumped out.

The drainage of the above two modes can discharge water into the sewer pipe, however, the clothes contain quite a lot of filament matters, such as fibers of clothes, hairs of human bodies and the like, the filament matters can be agglomerated in the water inlet sewer pipe, the sewer pipe is blocked after the agglomeration, and the cleaning is very inconvenient.

Therefore, we have designed a drainage filtering device of laundry equipment, which can be installed at the outside of a washing machine, for connecting between a drainage pipe and a sewer pipe of the washing machine, and can realize drainage filtering.
