Turbine oil smoke absorbing fan

Abstract

The invention discloses a turbine oil smoke absorbing fan composed of a main shell with an oil smoke absorbing air inlet, a power air drafting device connected with the main shell, and an air outlet. The power air drafting device is a turbine fan blade driven by a motor, a turbine shell connected with a main shell framework is arranged outside the turbine fan blade, and the turbine shell is a cylindrical structure. The air outlet is arranged at the side of the turbine shell and communicated with the inner cavity of the turbine shell integrally. The main shell is composed of a ventilating duct connected with the turbine shell, and an oil smoke absorbing cavity connected with the ventilating duct and extended forwards. A grid-type net is arranged at the air inlet at the front end of the oil smoke absorbing cavity. The invention adopts a technique that combines the turbine structure of a range hood with a main structure of an exhaust fan, not only has the advantage that the range hood highly effectively separates the oil smoke, but also inherits the advantages that the exhaust fan has a simple structure and small volume. The turbine oil smoke absorbing fan can not only separate the oil smoke for two times and greatly decrease the pollution levels of fan and air, but also greatly decrease cost.

Description

Technical field [0001] The invention relates to the technical field of range hoods, and more specifically to a turbo-type range hood fan. Background technique [0002] China is a country that pays attention to food. In food processing, frying, frying, cooking, and frying account for a large proportion. Therefore, the oil fume in Chinese kitchens is very large, which is not only harmful to the human body, but also easy to make the kitchen environment. It is greasy and not easy to clean. For this reason, people have used many methods to improve the kitchen environment. At first, people installed exhaust fans in the kitchen to exhaust harmful gases such as cooking fume out of the room, but the disadvantages of exhaust fans are obvious. After a period of time, not only the entire exhaust fan is stained with oil, but also on the wall. It is full of oil stains. In view of this, the Ministry of Commerce of China introduced the first range hood at the Munich Trade Fair in Germany. It mai...

Problems solved by technology

However, this range hood only has a partition-like oil fume separation device, which can only isolate part of the oil droplets in the flue gas. Therefore, after a long time of use, the fan blades and air outlet of the fan will still be covered with oil droplets. , not only ugly, but also affect the life of the range hood
