Background technique

With the improvement of living standards, dishwashers have gradually entered ordinary Chinese families; in Western countries, the penetration rate of household dishwashers has reached 60%-70%, while the existing penetration rate in China is less than 10%, so Has a very broad market prospects.

General dishwashers are equipped with a cleaning tank and a cleaning water pump connected to the cleaning tank. However, as the residual grease and other stains in the tableware will condense and solidify on the surface of the tableware to form hard crystals after the temperature is lowered, it is often difficult to completely remove the above stains only by circulating the water pump.

Therefore, there has been a dishwasher that rinses after heating the cleaning water. Although the dishwasher can soften the hard crystals by heating the cleaning water, it takes a long time to heat the cleaning water, thereby reducing the time required for the dishwasher. cleaning efficiency.

In addition, the bowl baskets of general dishwashers for carrying dishes are all fixed. There are also multiple nozzles facing the bowl baskets in the dishwasher. Clean the dishes in the bowl basket to achieve the purpose of cleaning. However, in this form of flushing, because the angle between the flushing water flow and the tableware is fixed, there will always be areas where the flushing water flow cannot be directly sprayed, which will affect the cleaning effect.
