Washing machine

Abstract

The invention relates to a washing machine. The washing machine comprises a tank, a spraying arm and a water pump, wherein the water pump at least comprises an impeller capable of pumping water in a washing cavity to the spraying arm, the impeller comprises a central shaft and a plurality of blades distributed on the outer surface of the central shaft at intervals, the blades extend axially on thecentral shaft and at least lower parts of the blades are gradually smoothly bent along the rotation direction of the impeller, the blades comprise first blades and second blades, and the widths, in the circumferential direction of the central shaft, of the first blades are greater than the widths, in the circumferential direction of the central shaft, of the second blades. For the washing machineprovided by the invention, the impeller of the open water pump with a novel structure is adopted, so that a water flow thrown to the spraying arm can form a turbulent flow, while the structures, on the central shaft, of the first blades and the second blades of the impeller are asymmetric, so that the speed in drawing the water flow by the impeller is not uniform, thus the water flow forms the pulse effect, the pulse type water flow can further generate the stirring effect for the water flow in the spraying arm, therefore, the turbulence intensity of the water flow is strengthened, and further, the washing effect is improved.

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine capable of forming turbulent and pulsed water flows to improve the cleaning effect. Background technique [0002] Along with improving day by day of people's living standard, dishwasher more and more enters family as a kind of kitchen appliance product. Dishwashers currently on the market are generally divided into three types: table type, cabinet type, and tank type. Among them, the table type dishwasher is an integral independent structure, which is generally placed on the table for use; , but needs to be embedded in the kitchen cabinet for use; the sink dishwasher is combined with the sink and is generally installed in the kitchen cabinet for use. [0003] The above-mentioned various forms of dishwashers generally use a water pump to lift water and spray it to the dishes in the cleaning space so as to achieve the cleaning effect. For example, the Chinese patent "Microco...

AI Technical Summary

Problems solved by technology

This structure requires the use of two water pumps, which weakens the advantages of the product in terms of production costs, and because the water flow submerges the spray arm when cleaning fruits and vegetables, the turbulent flow intensity of the water flow will be affected, thereby affecting the cleaning effect
