Why does the hood have fan blades?

A range hood is an essential appliance in the home kitchen. Its main function is to purify the air in the kitchen by removing smoke, steam and oil vapors. The reason why the range hood can effectively remove kitchen fumes and odors is mainly due to the fan blades in its internal structure.

The fan blade is one of the key elements inside the kitchen hood. Its function is to guide the exhaust gas to exhaust various odors and oil vapors in the home kitchen. When the smoke enters the hood through the filter and the oil cup above the hood, the rotating force of the motor fan rotates the blades at the same time, and the smoke and other waste gases are exhausted towards the outside from the inside. of the hood.

Fan blades are usually made of aluminum and plastic. These two materials have a strongresistance to corrosion and high temperatures. When designing fan blades, symmetrical blade structures are generally used, which can effectively improve the air extraction capacity, reduce noise and increase the stability of fan operation.

In addition to the symmetrical blade structure, there is another similar design called airfoil blades. The advantage of aerodynamic blades is that they have good aerodynamic properties, which can improve the air extraction capacity and increase the life of the fan.

In addition, some kitchen hoods use a direct-drive motor structure to directly attach the fan blades to the motor shaft, thereby reducing the vibration and noise of the transmission device and improving performance. work efficiency.

In short, the kitchen hood fan blades are a key elementto eliminate cooking fumes and odors. By designing a reasonable blade structure and using high-quality materials and direct drive motors, the air extraction capacity can be significantly improved and the stability and service life of the fan can be guaranteed.
