Oil screen device of European style range hood

Abstract

The invention discloses an oil screen device of an European style range hood, which comprises an outer oil screen part and an inner oil screen part, wherein the inner oil screen part is arranged on the inner side of the outer oil screen part; an oil screen body is formed by the inner oil screen part and the outer oil screen part integrally, and comprises a main air inlet surface and two side air inlet surfaces connected with the two sides of the main air inlet surface respectively; the main air inlet surface is arranged obliquely; an included angle formed between the main air inlet surface and a horizontal plane is 5-85 degrees; air inlets in the inner oil screen part of the main air inlet surface are positioned above air inlets in the outer oil screen part of the main air inlet surface; air deflectors are obliquely arranged on one side of each air inlet in the inner oil screen part of the main air inlet surface; and an included angle formed between each air deflector and a plane of the inner oil screen part of the main air inlet surface is 20-50 degrees. The oil screen device of the European style range hood is smooth in air intake; a suction force of the range hood is not affected; the phenomena that much oil fume runs away and is not sucked are avoided; and the volume of an oil cup can be increased, thereby reducing the oil dumping times and the cleaning times of the oil cup.

Description

technical field [0001] The invention relates to a range hood, in particular to a European-style oil net device for a range hood. Background technique [0002] Domestic research results show that cooking fume, as a unique pollution source in my country, has an increasingly significant impact on the quality of the urban air environment. Especially in recent years, with the development of China's urbanization and the adjustment of industrial results, the catering industry has developed rapidly. The use of cooking oil is increasing day by day. Cooking fume is an important source of urban aerosols. Some experts have suggested that the high content of organic matter in China's PM2.5 may be related to the particularity of Chinese traditional food culture. The toxicity of kitchen fume mainly includes: genotoxicity to the substrate, immunotoxicity, lung toxicity and potential carcinogenicity. Cooking oil fume pollution and its harmful effects on human health are indoor environmental...

AI Technical Summary

Problems solved by technology

The inner net and the outer net are respectively provided with a plurality of parallel air inlets vertically arranged, and the air inlets of the inner net and the outer net are longitudinally spaced and arranged in a misplaced manner. This kind of oil net device will have the defect that the air intake is not smooth, thus Reduce the suction force, resulting in ...
