Every time the motor 71 rotates, the water pump 101 sucks the oil dirt connected to the oil cup 54 and sprays it from the spray head 106 to the impeller of the host machine 1 to treat the oil dirt cleaned by the cleaning device.

When the work of the cooker hood is completed, the switch 8 is turned off, the motor 71 is turned on, and the coil plate 4 is rotated to return the coil plate 4 to the initial position. In the machine chamber 6, while the coil plate 4 is rotating, the cleaning device will clean the other section of the coil plate 4, the work is completed, and the host 1 and the motor 71 stop running.

When the main unit 1 needs to be disassembled, washed, repaired and replaced, the range hood can be easily removed and loosened by loosening the bracket screws, unlike the range hoods on the market, which require complete unit replacement and complete unit warranty.

When the host 1 runs for a month or two and needs to clean the host 1, open the dark room 102, and add a suitable cleaning liquid to the cleaning liquid bottle 105. When the motor 71 rotates, the water pump 101 will rotate, and the water pump 101 will pass through the water inlet pipe 103. The connector 104 sucks the cleaning liquid from the cleaning liquid bottle 105 and sprays it from the outlet pipe of the water pump 101 to the impeller of the host 1 through the nozzle 106, so that every time the motor 71 is turned on, a small amount of cleaning liquid will be atomized in the nozzle 106 Then, the impeller is sprayed toward the host 1, and the host 1 can be cleaned.
