The utility model discloses the theory of operation:

(one) a washing preparation stage. After the gas hood type dish washer is electrified, the hood cover 2 is pulled down after the operation display screen 17 presses a start key, and the magnetic control switch 13 feeds back a signal for detecting that the hood cover 2 is pulled down to the controller 22. The water level probe 11 detects that the washing tank 5 is lack of water and feeds information back to the controller 22, and the controller 22 controls the water inlet electromagnetic valve 9 to be opened to supply water to the gas water heater 4. After the gas water heater 4 heats the water to 60 ℃, hot water is sprayed out through the rinsing and disinfecting spray pipes b of the upper swing arm spray device 8 and the lower swing arm spray device 7 to be supplied to the washing tank 5 until the water level probe 11 in the washing tank 5 detects that water exists, and the gas water heater 4 heats the water in the tank to 80 ℃ for rinsing, disinfecting and spraying. When the condition that the water level probe 11 in the washing cylinder 5 detects that water exists, the temperature probe 12 detects that the temperature is 60 ℃, the temperature of the water in the gas water heater 4 is 80 ℃, and the operation display screen 17 displays and reminds. At this time, the tableware to be washed is put into the washing tank 5, the uncovering handle 16 is pulled down, the cover 2 is pulled down and extends into the washing tank 5, and the controller 22 automatically controls the high-pressure water pump 3 to operate, so as to start the main washing process.

(II) a main washing stage. Water in the washing cylinder 5 is pressurized by the high-pressure water pump 3 and then sprayed out through the main washing spray pipes a of the upper swing arm spray device 8 and the lower swing arm spray device 7, the main washing spray pipes a rotate at a high speed, water flow is sprayed out in a rotating mode, 360 degrees of dead angles are avoided, and tableware is washed, so that stains on the surface of the tableware are washed completely. Water flows into the washing cylinder 5 through the slag plate 6, so that a water path is formed for washing and recycling. The residue plate 6 filters the residue washed by the tableware. And (4) after the main washing process is finished, entering a high-temperature rinsing and disinfecting process.

And (III) a high-temperature rinsing disinfection stage. High-temperature hot water at 80 ℃ in the gas water heater 4 is sprayed out through the rinsing and disinfecting spray pipes b of the upper swing arm spray device 8 and the lower swing arm spray device 7 to wash and disinfect tableware at 360 degrees at high temperature. The oil stain washed by the tableware is not mutually melted with water, the oil floats on the water because the density of the oil is lower than that of the water, and the oil stain in the washing tank 5 can be discharged from the sewage discharge overflow pipe 10 by the water for rinsing and disinfection. When the disinfection is finished, the operation display screen 17 displays and prompts, and the whole tableware cleaning process is finished. The lid 2 can be opened by pulling the lid-removing handle 16 upward, and the washed dishes can be taken out.

The gas hood type dish washer of the utility model has reasonable structural design, small volume, easy manufacture and high automation degree; the heating is fast, the water consumption is less, the energy is saved, the environment is protected, and the cleaned tableware can meet the requirements of the disinfection and sanitation standard of tableware (drinking).
