Oil filter of range hood

Abstract

The invention discloses an oil filter of a range hood. The oil filter comprises at least two oil fume channels which are arranged side by side. The oil filter is characterized in that a main body of each oil fume channel is a cylindrical oil filter pipe; openings in two ends of the oil filter pipe are used as air outlets; a partial opening formed in the side wall of the middle of each oil filter pipe is used as an air inlet the periphery of which extends downwards so as to form an air hood. One integrally formed oil filter pipe alone forms an oil fume channel, so that the high requirement of a part on the production accuracy, due to installation needs and the like, is avoided, the production difficulty is lowered and the cost is saved; as each oil fume channel is formed by one single oil filter pipe, the seal performance of each oil fume channel is guaranteed, the leakage of the fume is avoided and the formation of cyclone after oil fume enters is guaranteed, and thus the effect of oil fume separation is guaranteed, the undesired pressure loss is avoided and the power consumption of a fan is lowered.

Description

technical field [0001] The invention relates to a range hood, in particular to an oil filter for the range hood. Background technique [0002] Along with the improvement of living standard, the raising of the requirement of quality of life, range hood is used widely in each family as the important electric appliance that sucks the lampblack that produces when cooking in the family kitchen. The main problem at present is that when the range hood is working, the oil fume passing through the air duct tends to accumulate a large amount of oil in the air duct. Due to the high viscosity of the formed oil, it is difficult to discharge from the air outlet of the air duct, causing oil pollution to the pipeline. The corrosion of the range hood reduces the service life of the range hood and increases the use and maintenance costs of the range hood, while the other part is directly discharged. The range hood contains a large number of carcinogens and substances with particles larger tha...

AI Technical Summary

Problems solved by technology

The oil fume passage of this patent is square, and there are the same problems as the above. The components (front panel, rear panel, medial partition and air deflector) together constitute the oil fume passage. Due to the limitation of the production process, it is easy to cause oil fume leakage at the connection of each component, especially the fastening of the air deflector and the front plate. The tight fit between the wind deflector and the front plate to avoid the formation of gaps requires very high production accuracy, and it is also difficult to position the front plate and the wind deflector to ensure a proper buckle during installation, which increases the difficulty of mold opening and installation, resulting in a decrease in production costs improve
