(1) The installation height of the range hood must be appropriate, which can not only ensure non-contact but also ensure the smoke exhaust effect.

(2) In order to avoid excessive noise or vibration, oil dripping and oil leakage. For the range hood, the oil fume pipeline of the range hood should be cleaned regularly to avoid excessive oil sticking to the inner surface of the motor, turbine and range hood.

(3) When using the range hood, keep the air in the kitchen circulating, prevent the air in the kitchen from forming negative pressure, and ensure the suction of the range hood.

(4) Consumers had better not disassemble the range hood for cleaning without authorization, because once the motor is not installed, the smoking effect cannot be guaranteed and the noise will increase; It's best to let the manufacturer's professionals clean it.

2, the method of cleaning the range hood:

(1) Steam flushing method of pressure cooker Boils the cold water in the pressure cooker. When the steam is continuously discharged, take a lower pressure valve, then turn on the range hood and aim the steam plug at the rotating blades. As the high-temperature steam continuously rushes into the blades and other parts, oily sewage will flow into the waste oil cup along the pipeline. Until there is no oil in the oil cup, the range hood has been cleaned and the pressure cooker can cease fire.

(2) Detergent vinegar soaking method Remove the impeller of the range hood, soak it in a pot of warm water, and mix 3 ~ 5 drops of detergent and 50 ml of vinegar in the warm water. Soak 10 ~ 20 minutes, then scrub with a clean rag, and use this solution to clean the shell and other parts. This method has no damage to human skin and no corrosion to equipment, and the surface still maintains its original luster. When restoring the installation, pay attention to keep the original angle of the oil circuit (pipe).

(3) Soap surface coating method: Soap is made into liquid paste, and then coated on the surfaces of impellers and other devices. After the range hood is used for a period of time, remove the impeller and other devices and wipe off the oil with a rag. This method is suitable for new and cleaned range hoods.
