Washing machine

Abstract

The invention relates to a washing machine. The washing machine comprises a tank, a spraying arm and a power assembly, wherein the spraying arm is arranged in the tank, and the power assembly is connected below the spraying arm. The washing machine further comprises an air pump and an air guide pipe, wherein the air pump is arranged at the outer side of the tank, the air inlet end of the air guidepipe is connected with the air pump, the output end of the air guide pipe extends into the spraying arm, an air collecting cavity connected with the output end of the air guide pipe is arranged in the spraying arm, and air guide channels extending towards the direction of water outlet holes of the spraying arm are formed in the air collecting cavity. For the washing machine, the guide channels can guide the added air, so that the added air is rapidly sprayed out from the water outlet holes after generating a cavitation effect with a water flow and generating air bubbles in the water flow, then the cracking failure of the air bubbles caused by the excessively long conveying flow of the water flow is avoided, when the water flow mixed with the air bubbles is sprayed to bowls and dishes, theair bubbles in the water flow crack after contacting the bowls and dishes and generate a relatively large impact force, so that the stubborn dirt on the bowls and dishes or vegetables and fruits is scattered, and then a very good washing effect is achieved.

Description

technical field [0001] The invention relates to a washing machine. 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 "Microcomputer Light-controlled Automatic Dishwasher" with the application number CN97236119.7 and the Chinese patent "A Dishwa...

Problems solved by technology

However, in this type of structure, the instantaneous air explosion between the ultrasonic waves and the high-pressure bubbles needs to be maintained in the water. When the water flow is lifted by the water pump and sprayed out in a circular manner, the high-pressure bubbles are difficult to reach the surface of the dish and rupture, which is not suitable for water flow. jet dishwasher

In addition, this type of structure is only suitable for large-scale dishwashers, and it is difficult to apply to household dishwashers.
