A bionic filter used in a range hood

Abstract

The invention relates to a bionic filter screen applied to a range hood. The bionic filter screen is arranged at a smoke cage hood at the lower end of a main engine of the range hood, and positioned at an air inlet at the upper end of an oil cup; a draught fan system provided with an air outlet is mounted in the main engine; the bionic filter screen is served as a big-end-up or big-end-down conical, rectangular conical or tetragonal conical metal thin shell; oil guide stems, oil trap stems and meshes are arranged on the bionic filter screen; the meshes take the shapes of parallelograms and are distributed with the oil guide stems with included angles; a plurality of the meshes are orderly and parallelly arranged at the upper and lower positions of the oil guide stems as well as symmetrically arranged at the left and right positions of the oil guide stems; the oil guide stems and the meshes are assembled as units and orderly distributed around the conical body of the bionic filter screen completely or partially; and the oil guide stems are parallel to the height h of the conical body of the bionic filter screen. The bionic filter screen provided by the invention is excellent in oil smoke trap, oil guide, resistance to oil dropping, resistance to oil hanging, and processing economy.

Description

technical field [0001] The invention belongs to the technical field of range hoods, and in particular relates to a bionic filter screen used for range hoods. Background technique [0002] Domestic research results show that as a unique type of pollution source in my country, cooking fume has an increasingly significant impact on the quality of the urban air environment. The toxicity of cooking fume is well known. At present, most range hoods use kitchen exhaust gas directly to the outside Practice; In order to improve the indoor and outdoor environment, the range hood's ability to absorb oil fume and separate oil fume is particularly important. The filter screen of the range hood is an important part of the range hood to capture and filter oil fume. The rationality of its design directly affects the effects of smoking, filtering, oil guiding, anti-gripping, anti-blocking, and economical efficiency. [0003] At present, the bionic filter screen of range hood is divided into m...

AI Technical Summary

Problems solved by technology

[0003] At present, the bionic filter screen of range hood is divided into mesh shape: square, rectangular, long waist hole, diamond hole, etc. The above meshes are excellent in capturing oil fume, guiding oil, preventing dripping oil, preventing oil hanging and processing economy. There are different degrees of defects, it is difficult to fully summarize
