Impeller structure for double-layer spraying system and cleaning machine applying impeller structure

Abstract

The invention relates to an impeller structure for a double-layer spraying system, which is characterized by comprising a first impeller and a second impeller, wherein the first impeller is provided with a shaft positioned in the center and first blades spirally wound on the peripheral wall of the shaft along the axial direction, the second impeller is sleeved on the periphery of the first impeller and can synchronously rotate along with the first impeller, and the second impeller is provided with second blades extending in the radial direction of the first impeller. According to the impeller structure capable of meeting the water flow and the water pressure of the double-layer spraying system, when the impeller structure is used, water flow on the lower layer is sucked upwards through the lower portion of the first impeller to keep the corresponding water flow, then the water flow is circumferentially dispersed through the second impeller, the high water pressure is ensured, and the lower layer has the high cleaning strength; and the upper layer draws water upwards through the upper portion of the first impeller, large water flow is kept, and then double-layer spraying is achieved. The cleaning machine with the impeller structure achieves double-layer spraying, cleaning dead corners can be eliminated, and the cleaning effect is improved.

Description

technical field [0001] The invention relates to an impeller structure used in a double-layer spray system and a cleaning machine with the structure. 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 water pumps to lift water and spray it to the dishes, fruits and vegetables in the cleaning space to achieve the cleaning effect. They use a single-layer spray system, and their impellers are ...
