In order to improve the effective oil smoke absorption area of range hoods and discharge as much oil smoke as possible, most range hoods adopt two air inlets. The usual structure is that two air inlets are respectively arranged on the left and right sides of a volute arranged in a range hood, a motor and a shell covering the motor are arranged in the volute, and the motor is connected with two impellers arranged on the left and right sides of the volute through a rotating shaft arranged on the motor.
When in use, the motor drives the left and right impellers to rotate, so that the sucked oil fume gas is separated again, and the purified smoke is discharged along the exhaust port arranged in the arc diameter changing direction of the volute. Because the above-mentioned motor needs to drive two impellers to rotate, it will generate a lot of heat in the working process, and if it cannot be discharged in time, it will affect the service life of the motor.

Precautions:
1, pay attention to the direction of the exhaust pipe of the range hood to avoid turning too much, the slope of turning should be small, the air outlet should be unobstructed, the smoking effect is good and the noise is low.
2. The power supply of the range hood must have a special socket. It depends on whether the electricity is in the unit, and it should be operated according to the specific situation to ensure the stability of the electricity rate.
3. Before ignition, turn on the range hood to ensure the indoor air is clean. When using the range hood, keep indoor circulation.
4. Pay attention to cleaning the range hood frequently, and often remove the filter screen for cleaning. Too much dust will increase power consumption.
