Background
The range hood has become one of the indispensable kitchen household electrical appliances in modern families. The range hood works by utilizing the fluid dynamics principle, sucks and exhausts oil smoke through a centrifugal fan arranged in the range hood, and filters partial grease particles by using a filter screen. The centrifugal fan comprises a volute, an impeller arranged in the volute and a motor driving the impeller to rotate. When the impeller rotates, negative pressure suction is generated in the center of the fan, oil smoke below the range hood is sucked into the fan, accelerated by the fan and then collected and guided by the volute to be discharged out of a room.
The following problems generally exist when the range hood is used for cooking in a kitchen at present: 1. the noise is large when the device is used; 2. the purification efficiency of the oil fume particles is low, and the oil fume can not be internally discharged; 3. when the door and the window are sealed, negative pressure occurs indoors, so that the smoking effect and the indoor air quality are influenced; 4. the kitchen temperature is high in summer and the air temperature is low in winter. The above problems affect the comprehensive experience of the user during cooking. For the problem of large noise, sound absorption cotton is usually arranged in the range hood or an active noise reduction method is adopted to reduce noise.
