In the circulation system of this invention, when the residue reach the first filtration unit, enter into blade position, and they are smashed by the blade. Part of the bigger residue will stay in the first storage unit, and directly be discharged of the dish-washing machine when the wash liquid discharging unit acts; some smaller residue will enter into main watercourse through filtration net of water inlet. Additionally, second water outlet is provided on the main watercourse, mixture of residue and water enter into the close area formed by filtration grid and filtration grid cover, then the residue flows into the second storage unit of wash liquid discharging unit through the residue collecting mouth, and will be evacuated when discharging water.
Description
Technical field
The present invention relates to a kind of wash mill of tableware, relate in particular to a kind of Dishwasher water passage circulation system.
Background technology
The tradition dish-washing machine generally includes a filter, and this device is used for filtering the cleaning solution of making dirty in washing process; A cleaning solution EGR (as washing pump) that is used for the cleaning solution after being filtered by filter is supplied to spray arm, and one be used for the cleaning solution tapping equipment (as emptying pump) of a part of cleaning solution outside filter is discharged into system.In washing process, washing pump extracts recirculated water to spray arm, and tableware is washed.For decontamination cycle water, at the water inlet of described washing pump screen pack is set, the residue filtering that particle in the recirculated water is bigger, and discharge dish-washing machine by emptying pump.
Yet in the water passage circulation system of traditional dish-washing machine, therefore less food particle can not, make residue participate in the reciprocation cycle of current by the effective filtering of filter of water inlet, causes the pollution once more to tableware.
Summary of the invention
The problem to be solved in the present invention provides a kind of water passage circulation system of dish-washing machine, can not make recirculated water keep clean to solve prior art, and clean the low defective of rate.
In order to address the above problem, the invention provides a kind of Dishwasher water passage circulation system, comprising:
The washing chamber by being arranged on the spray arm spray washing liquid in the described washing chamber, is placed on the residue on the object in the described washing chamber with cleaning;
