Method and device for improving efficiency of residue removal and residual discharge of dish washing machine

Abstract

The invention relates to a method for improving the efficiency of residue removal and residual discharge of a dish washing machine. The method comprises the steps that 1) water and residues enter intoa third channel of a drainage chamber, the third channel is formed in the portion close to the side wall of a cavity of the drainage chamber, and the flow direction of the water in the channel is longitudinally downward; 2) multiple rotatable stirring sheets are arranged in the drainage chamber, the other side edges of the stirring sheets extend to the lower portion of the third channel, and therotation trajectories of the outer side edges horizontally sweep through the portion below the third channel; the stirring sheets rotate, the water and residues are stirred to the side wall of the cavity of the drainage chamber, the suction force is generated on the water in the third channel at the same time, and accordingly the speed of the water and residues passing through a residue removal mechanism is increased; 3) the opening portion of a water outlet of the drainage chamber faces the rotating center of the stirring sheets; when the outer side edges of the stirring sheets are close to the water outlet, the water and residues are stirred into the water outlet and discharged from a drainage channel. The stirring sheets stir the water and residues, and the speed of the residues entering the water outlet is increased; meanwhile, the stirring sheets and the cavity achieve a pumping function, and the suction force can be generated on fluid in the residue 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
