Current dish washers are classified into a spray type and an ultrasonic type according to washing principles.
Jet dish washer: in the dish washing process of the dish washing machine, the mechanical washing of the surface of the tableware is carried out by the high-temperature high-pressure water jet, the saponification and decomposition of the greasy dirt and residues on the surface of the tableware are carried out by the detergent, the soaking and swelling of the food residues are carried out by the hot water, the greasy dirt, the residues and the food residues on the surface of the tableware are rapidly decomposed and fall off, and the surface of the tableware is clean and bright. Under the dual functions of scouring of the high-temperature and high-pressure water column and powerful decontamination of the detergent, harmful germs are effectively eluted, and the dual effects of cleaning and degerming are achieved.
Ultrasonic dish-washing machine: the ultrasonic dish washing machine utilizes the principle of ultrasonic cleaning: when ultrasonic waves pass through the liquid medium, the liquid medium is pressed to vibrate at a very high frequency, so that liquid molecules generate shock waves with alternating positive and negative polarities. When the sound intensity reaches a certain value, micro cavitation bubbles grow rapidly in the liquid and are closed instantly and strongly, and strong micro explosion and shock waves are generated to destroy the dirt on the surface of the cleaned object and fall off from the cleaned surface. Although the action of each cavitation bubble is not great, hundreds of millions of cavitation bubbles act every second, so that the cleaning effect is good. Since the ultrasonic waves can penetrate the solid matter to vibrate the entire liquid medium and generate cavitation bubbles.
The two dishwashers have the defects of low dish washing speed and insufficient cleanness.

the preparation is that the tableware is placed on the dish washing rack and is fixedly placed in the washing cylinder 3, the cover door 31 is closed, and the power is switched on.
First, flush forward.
And closing the second water inlet 92, opening the first water inlet 91, starting the motor 10 to drive the axial flow pump 9 to operate, conducting the first water inlet 91, pumping an external water source into the washing cylinder 3 through the axial flow pump 9, and simultaneously opening the washing liquid storage 12 to add the washing liquid into the water.
The temperature of the externally introduced water should be about 60 ℃, so that oil stains can be better removed.
Due to the adoption of the axial flow pump 9, a high-kinetic energy rotating water flow can be formed, and the water is pressurized, rotated and pushed in clockwise or anticlockwise under the stirring action of the spiral blade, so that the tableware placed on the dish washing rack is spirally washed.
According to the vortex principle, the cylindrical washing cylinder 3 is easy to form a rotating water flow, and simultaneously, the spiral high-speed washing of the water flow is kept under the guidance of the spiral flow deflector 32.
And secondly, reversely flushing.
