[0034] Working principle: When cleaning the evaporator, the motor 9 is turned on, and the motor 9 drives the drum 11 to rotate. The rotation of the drum 11 drives the rotating column 12 to rotate along the center point of the drum 11, thereby moving the rotating column 2 14 through the connecting shaft 13, thereby driving the pressing plate 15 to move up and down, so that positive and negative pressures are formed in the pressurized barrel 17, and the cleaning liquid at the bottom of the double-layer box 8 is sucked into the cleaning pipe 7. A part of the cleaning liquid enters the pressurized barrel 17 through the water pipe 16, thereby pressurizing the entire cleaning liquid, so that the cleaning liquid passes through the cleaning pipe 7 is sprayed out to clean the inside of the evaporator. After cleaning, water is introduced through the water inlet pipe 2 to discharge the internal cleaning liquid through the water outlet pipe 4. When cleaning the scale in the liquid inlet pipe 19, the handle 24 is turned to drive the shaft 22 to rotate, thereby driving the ball valve 25 to rotate to the corresponding position, and water is introduced into the liquid inlet pipe 19.
