At present, household dish washing machines all use a water spray cleaning mode, however, on one hand, the common Chinese tableware is difficult to clean due to the problem of the water spray angle of the water spray type dish washing machines, on the other hand, the cleaning effect is always bad and satisfactory due to the fact that the contact time of cleaning liquid and the tableware is short after the cleaning liquid is sprayed, meanwhile, the special dish washing powder used by the household dish washing machines is very expensive, and the use cost is high. In view of this, the water spray type dishwasher has not been popularized in the domestic countries.

Commercial dishwashers use a water immersion method for dish washing, but cannot be used in households. On one hand, the water immersion type dish washing machine adopts ultrasonic waves, but has the problems of noise and the possibility of potential harm to human bodies; on one hand, when the dish-washing machine uses water liquid to wash the soaking type tableware, because a large amount of oil stains are attached to the surface of the tableware, especially in a Chinese cooking mode, the oil stains of the tableware are more serious, so that the large amount of oil stains enter the water to be washed along with the tableware and float on the water surface, and the generated water surface oil film can secondarily pollute the tableware; on the other hand, when the dish washer uses the water liquid to wash the soaking type tableware, because a large amount of food residue is attached to the surface of the tableware, the food residue enters the water to be washed along with the tableware and floats in the water, and the washing effect is poor.

3) the dish rack is linearly reciprocated or rotated to form a vortex to drive the tiny air bubbles to be uniformly distributed in the washing liquid, and the vortex enables the washing liquid containing the tiny air bubbles to wash the tableware;

4) discharging the washing liquid;

and repeating the steps 1-4 to carry out circulating washing until the tableware is cleaned completely to finish the washing process.

As a further improvement of the technical scheme, the interior of the dish rack is divided into a plurality of placing spaces, and part of the placing spaces are set to be adjustable in size, so that tableware can be randomly placed into the dish rack with the plurality of placing spaces.

As a further improvement of the technical scheme, the floating oil floating on the surface of the cleaning solution in the washing process is removed by using a floating oil escaping device.

As a further improvement of the above technical solution, a continuous filtration device is used to filter the washing liquid containing floating residues during the washing process.

As a further improvement of the above solution, the washing liquid is heated to 70 ℃ using a heating device.

As a further improvement of the above technical solution, a detergent is added to the washing liquid.

As a further improvement of the technical scheme, the number of times of the cyclic washing is at least three.

As a further improvement of the technical scheme, when the bowl frame moves linearly and reciprocally, the speed is 20-100 times/min.

As another improvement of the technical scheme, when the bowl frame rotates, the speed of the bowl frame is 20-100 revolutions per minute.
