Residue removing waterway structure and dish-washing machine

Abstract

The invention provides a residue removing waterway structure and a dish-washing machine; the residual removing waterway structure comprises a water flushing pipe, a pressure releasing pipe and a drainage pipe; the water inlet end of the water flushing pipe is connected with a water source; the water outlet end of the water flushing pipe is connected to the water inlet end of the pressure releasingpipe; the water outlet end of the pressure releasing pipe is used for being connected to the drainage pipe; the pressure releasing pipe is provided with a throat part used for generating negative pressure; the cross sectional area of the throat part is smaller than the cross sectional area of other parts of the pressure releasing pipe; the cross sectional area of the pressure releasing pipe fromthe throat part to the water outlet end of the pressure releasing pipe is increased; one end of the drainage pipe is connected to the throat part; and the other end of the drainage pipe is used for being connected with the drain opening of a water cup of the dish-washing machine. According to the residue removing waterway structure and the dish-washing machine provided by the invention, after normal drainage of the dish-washing machine is completed, residual water still exists in the water cup of the dish-washing machine, at the moment, water is flushed by the water source to the water flushing pipe, the water flow is discharged through the water flushing pipe and the pressure releasing pipe, negative pressure is formed in the throat part, and the water remaining in the water cup is suckedinto the pressure releasing pipe to be discharged.

Description

technical field [0001] The invention belongs to the technical field of kitchen appliances, and more specifically relates to a residual water channel structure and a dishwasher. Background technique [0002] The emergence of dishwashers has greatly reduced the work of washing dishes and reduced heavy manual labor. The current working principle of dishwashers on the market is: use water to wash tableware and kitchen utensils, combine the chemical action of detergent and the effect of high temperature to promote the removal of stains, and realize the cleaning of tableware. Therefore, the water flow system of the dishwasher is its core system. The water flow system of the dishwasher includes the washing cycle system, water inlet and drainage system. The drainage system usually uses a drainage pump to suck the water in the water cup, and at the same time squeeze the water in the pump cavity and discharge it to the drain pipe. Obviously, when the drain pump is started for a per...
