Dishwasher and its filter system, slag discharge device

Abstract

The invention provides a dishwasher, its filtration system, and a slag discharge device, wherein the slag discharge device includes a water cup, a spray arm seat and a washing pump, the water cup has a chamber for accommodating the spray arm seat, and the spray arm seat is fixed in the cavity The chamber is divided into a water supply chamber and a filter chamber. The water supply chamber is provided with a cup water inlet connected with the discharge port of the washing pump. The bottom of the filter chamber is provided with a slag discharge port. The slag discharge device also includes The slag collection port is set adjacent to the slag discharge port and located above the slag discharge port. The slag collection port is connected to the water supply chamber and the filter chamber; the washing pump is in the working state, and the washing water discharged by the washing pump is above the slag discharge port through the slag discharge port. Form a water wall and impact the side wall of the filter chamber to reflect back to the filter chamber; the washing pump is in a non-working state, and the residue collected in the filter chamber is discharged through the slag discharge port. The present invention not only omits the non-return sheet, but also improves the slag discharge capacity compared with the slag discharge device of the dishwasher with the non-return sheet without affecting the filtering ability.

Description

technical field [0001] The invention belongs to the technical field of dishwashers, and more specifically relates to a dishwasher, a filtering system and a slag discharge device thereof. Background technique [0002] The traditional dishwasher circulation filter system includes a slag collection port, a slag collection channel, a slag collection chamber, a filter screen, a slag discharge port, and a slag discharge channel, and some of the slag discharge channels include non-return pieces, and some do not Return sheet; for the circulating filter system with non-return sheet in the slag discharge channel, when the dishwasher is filtering, the non-return sheet will close the slag discharge port or slag discharge channel to prevent the washing water or filtered The residue is discharged through the slag discharge port and the slag discharge channel; when the dishwasher is discharging slag, the movement of the non-return piece switches the slag discharge port or the slag discharg...

AI Technical Summary

Problems solved by technology

This kind of slagging structure in the prior art, because the non-return effect of the non-return sheet itself is poor, and the switch is not flexible, it also has an obstructive effect on the residue; and for the circulating filtration system without the slag discharge channel, the The disadvantage is that when the circulating filtration system collects slag, the residue in the slag collecting chamber will be directly discharged through the slag discharge channel, and the filtering capacity of the circulating filtering system will be weakened. Therefore, how to improve the slagging capacity without affecting the filtering capacity become an urgent problem
