Filtering system for dishwasher

Abstract

The invention discloses a filtering system for a dishwasher, comprising an inner bag of a dishwasher, a water cup, a first channel connected with the water cup of the dishwasher and a drainage pump arranged on the first channel. A self-cleaning filtering residue removing device also comprises a filtering cavity; a filtering net is arranged in the filtering cavity; the filtering cavity is divided into a first cavity body and a second cavity body by the filtering net; the first cavity body is connected with the other end of the first channel; the second cavity body is connected with the inner bag of the dishwasher by the second channel; the first cavity body is also connected with a drainage pipe and the drainage pipe is provided with a drainage valve. The drainage pump is used for making washing water forcibly participate an individual filtering circulation system, thereby performing the cleaning and filtering function on the washing water; and simultaneously, food residues are collected and discharged, thereby enhancing the washing efficiency of the dishwasher, reducing the washing water and saving the washing time. The provided filtering residue removing device also has the function for automatically cleaning the filtering net.

Description

technical field [0001] The invention relates to an internal circulation filter structure of a dishwasher, in particular to a filter system for filtering water and collecting slag of the dishwasher. Background technique [0002] For current dishwashers, the circulating filter device is as attached figure 1 As shown, it includes a dishwasher liner 1, a water inlet pipe 2, a water cup 3 at the bottom of the dishwasher liner, a flat filter 4 and a cylindrical filter 5 in the water cup 3, and a washing pump 6 connected to the water cup 3. Planar filter 4 and cylindrical filter 5 have the functions of filtering washing water and collecting residues. The washing pump 6 pumps the filtered circulating water into the upper and lower spray arms 7, 8 and then enters the dishwasher liner 1 to participate in circulating washing. Waste water is discharged by drainage pump 9 after washing. Since the drainage pump only participates in the drainage work, the drainage pump has not been full...

AI Technical Summary

Problems solved by technology

Since the drainage pump only participates in the drainage work, the drainage pump has not been fully utilized; the washing system and the circulating filtration system share a washing pump, and the circulating water can only enter the circulating washing through the washing pump, so the recycling efficiency of the circulating water is low. And its filtering water and collecting residue mainly rely on the one-time purification of flat filter and cylindrical filter, so the effect of filtering water and collecting residue is not very ideal, and it needs enough washing cycles to achieve better filtering effect , so water consumption, time consumption, energy consumption

[0003] In addition, the filter system of the dishwasher usually does not have the function of self-cleaning, and usually needs to disassemble the filter screen and other components for cleaning, so it is time-consuming and laborious.

If it is not cleaned for a long time, it will also reduce the cleaning efficiency of the dishwasher and cause secondary pollution to the tableware.
