Range Hoods Appliances

In daily life, the smooth exhaust of kitchen cooking fume extraction fans in household use directly affects the normal operation of the kitchen, and the reasonable design of kitchen cooking fume extraction fans is a prerequisite for the subsequent installation of cooking fume purification devices. Commonly used kitchen cooking fume extraction fans include axial fans, fan boxes, and centrifugal fans.

The cooking fume extraction fans are usually installed on the upper part of the stove, connected to the power supply of the cooking fume extraction fan, driving the motor, making the fan wheel rotate at high speed, A negative pressure zone is formed within a certain space above the stove, and the indoor oil smoke gas is sucked into the interior of the range hood. The oil smoke gas is filtered through an oil screen for the first oil smoke separation, and then enters the air duct of the range hood. The oil smoke gas is separated for the second time by the rotation of the impeller. The oil smoke in the fan is subjected to centrifugal force, and the oil mist condenses into oil droplets, which are collected through the oil path to the oil cup, The purified flue gas is finally discharged along a fixed path.
