Filtration system of dish-washing machine

Abstract

The invention relates to a filtration system of a dish-washing machine. The filtration system comprises a plane filter, a cylindrical surface filter, a circulating filter, a water glass, a washing motor arranged at the outer side of the water glass and a drainage pump, wherein the plane filter and the circulating filter are respectively fixed on the upper end of the water glass; the cylindrical surface filter is fixed on the plane filter; the water glass is internally provided with a slag disintegrating cavity and a circling filtration pump cavity; the slag disintegrating cavity is communicated with an opening at the lower end of the cylindrical surface filter and a drainage pump cavity of the drainage pump; the slag disintegrating cavity is also internally provided with a slag disintegrating blade which is arranged on an output shaft of the washing motor and disintegrates food slag; the circling filtration pump cavity is communicated with the slag disintegrating cavity; a filtering net is arranged on a water inlet of the circling filtration pump cavity; the circling filtration pump cavity is internally provided with a circulating filtration pump arranged on the output shaft of the washing motor; the circling filtration pump cavity is communicated with a circulating filtration cavity of the circulating filter; and the circulating filtration cavity is communicated with the drainage pump cavity provided with the drainage pump. The filtration system can guarantee food slag not to be adhered to the filtering net, greatly promotes filtering effect and the self-cleaning capability of the whole filtering system, reduces energy and water consumption of the dish-washing machine, and increases the clearing rate of the dish washing machine.

Description

technical field [0001] The invention relates to a filter system of a dishwasher, which belongs to the modification technology of the filter system of the dishwasher. Background technique [0002] There are two types of filter systems used in existing dishwashers: one filter system has two or three layers of filters, the washing water enters the water cup through the flat filter screen and the cylindrical filter screen, the flat filter screen is for coarse filtration, and the column filter screen The surface filter is relatively fine, and the mesh of the filter is reduced layer by layer, and the food residues of different sizes are filtered layer by layer to achieve the filtering effect. This filter system needs the holes of the filter screen to be small enough to achieve better filtering effect. However, due to the huge suction force of the washing pump, the small hole of the filter screen, and the insufficient water passing area, the filtered food residues of large and sma...

Problems solved by technology

But because most of the fine food residues that are broken up will enter the washing cycle, this food residue will clog the nozzle of the spray arm, and at the same time, it will recontaminate the tabl
