Abstract

The invention relates to the technical field of dishwashers, in particular to a drainage system of a dishwasher. The drainage system of the dishwasher comprises a water cup, the water cup is providedwith a drainage port, the drainage port is connected with a drainage channel, the drainage channel is connected with a centrifugal impeller drainage pump, and a drainage pipe is arranged behind the drainage channel; a forced discharge port is formed nearby the lowest portion of an inner cavity formed by communicating the water cup with a drainage pump shell and connected with a forced discharge pipe, and the forced discharge pipe is further provided with a volumetric forced discharge pump and a residual water backflow prevention device such as a valve structure. The drainage system can completely drain residual water in the dishwasher and keep the dishwasher clean and hygienic.

Description

technical field [0001] The invention relates to the field of dishwasher technology, in particular to the drainage system of the dishwasher. Background technique [0002] With the continuous improvement of people's living standards, household dishwashers have gradually entered many families to replace the tedious labor of manually cleaning tableware. Among them, according to different door opening forms, household dishwashers can be roughly divided into pull-down door dishwashers, drawer dishwashers, and sink dishwashers. [0003] The water flow system of most dishwashers is roughly the same: there is a water cup at the bottom of the washing chamber, and there are several stages of filtration systems in front of the water cup; there is a water suction port in the lower part of the side wall of the water cup, which is connected to the circulating water pump. It is sent to each spray arm to form a spray cleaning of the tableware; there is a drain port at the lowest position of...
