A method and device for improving the slag removal and slag discharge efficiency of a dishwasher

Abstract

The invention relates to a method for improving the slag removal and slag discharge efficiency of a dishwasher: 1) The water body and waste residue enter the third passage of the drainage chamber, and are arranged at a position adjacent to the side wall of the drainage chamber cavity, and the flow direction of the water body in the passage is 2) Several rotatable paddles are arranged in the drainage chamber, the outer edge of the paddle extends below the third channel, and the rotation track of the outer edge sweeps across the bottom of the third channel; the paddle Rotate to move the water body and waste residue to the side wall of the cavity of the drainage chamber, and generate suction to the water body in the third channel at the same time, so as to improve the speed of the water body and waste residue passing through the slag removal mechanism; 3) The water outlet mouth of the drainage chamber faces Rotation center of the paddle; when the outer edge of the paddle is close to the water outlet, the water body and waste residue will be dialed into the water outlet and discharged from the drain. The paddle moves the water body and waste residue to increase the speed of waste residue entering the water outlet; at the same time, the paddle and the cavity form a pumping function, which can generate suction force for the fluid in the slag removal mechanism.

Description

technical field [0001] The invention relates to kitchen and bathroom equipment, in particular to a method and device for improving the slag removal and slag discharge efficiency of a dishwasher. Background technique [0002] For dishwashers, the waste residue is usually filtered and sent to the residue removal mechanism, which is pulverized and then discharged by the residue removal mechanism, such as the method shown in the disclosed technology called "Food Waste Disposer" (Patent No. Among them, the waste slag discharged by the slag removal mechanism is discharged with the flow of waste water, it is difficult to have a high discharge efficiency, the discharge effect is not ideal, and the waste slag is difficult to empty, which affects the cleanliness of the whole machine; for this reason, the inventor An improved technology is proposed, a drainage pump is arranged outside the drainage chamber (or drainage cavity), and the waste water and waste residue in the drainage chamb...

Problems solved by technology

[0002] For dishwashers, the waste residue is usually filtered and sent to the residue removal mechanism, which is pulverized and then discharged by the residue removal mechanism, such as the method shown in the disclosed technology called "Food Waste Disposer" (Patent No. Among them, the waste slag discharged by the slag removal mechanism is discharged with the flow of waste water, it is difficult to have a high discharge efficiency, the discharge effect is not ideal, and the waste slag is difficult to empty, which affects the cleanliness of the whole machine; for this reason, the inventor An improved technology is proposed, a drainage pump is arranged outside the drainage chamber (or drainage cavity), and the waste water and waste residue in the drainage chamber are sucked with the pumping capacity of the drainage pump, for example, it is called "dishwasher" (notification number CN 101902948B) In the scheme shown, a discharge pump is installed on the slag discharge pipeline, but this method of pumping waste slag has some defects: the residue will enter the drainage pump with the water flow, which will easily cause the drainage pump to be blocked and even the impeller of the drainage pump to be damaged. The situation of being worn and interrupted occurs; for this reason, some inventors have proposed a further improvement technology, such as the disclosed technology called "Dishwasher Multiple Slag Filtration System" (CN 105342536A), which is to improve the slag removal mechanism The waste residue is treated to a smaller volume to realize the above-mentioned defects of the drainage pump being vulnerable; however, the existing technologies including the above-mentioned improved technology only prolong the life of the drainage pump to a limited extent, and still cannot fundamentally solve the problem that the pump is damaged by waste residue defects, and there are problems such as large volume of the whole machine, high manufacturing cost and low efficiency of slag discharge
