Fume filer of range hood

Abstract

The invention relates to a fume filer of a range hood, which comprises an inner mesh enclosure (1) and an outer mesh enclosure (2), wherein installation plane surfaces (11, 21) are arranged at the bottoms of both the inner mesh enclosure and the outer mesh enclosure; the outer mesh enclosure and the inner mesh enclosure are mutually independent; and the two installation plane surfaces are connected together through a connecting structure. The invention is characterized in that the connecting structure comprises a connecting piece (4) and a positioning sleeve cover (5); the connecting piece isprovided with a columnar part (41) which extends upward; a blocking part (42) which horizontally extends outward is arranged on the lower part of the columnar part; the columnar part moves upward andpenetrates through the installation plane surface of the inner mesh enclosure to be fixed with the positioning sleeve cover; installation holes (22) matched with the blocking part in shape and size are arranged on the installation plane surface of the outer mesh enclosure; and the blocking part penetrates downward out of the installation hole, and after the blocking part is rotated for an angle horizontally, the lower end surface of the installation plane surface of the outer mesh enclosure is placed on the upper end surface of the blocking part. When in disassembly, after the connecting piece is rotated to align the blocking part on the connecting piece with the installation hole, the outer mesh enclosure can be detached easily relative to the inner mesh enclosure.

Description

technical field [0001] The invention relates to an oil fume filtering device of a range hood. Background technique [0002] Range hoods all have air inlets. In order to solve the technical problem of oil leakage dripping onto the cooking surface, the designer has provided a wind cover (or net cover) on the air inlet that can filter oil fume, and a wind cover at the lower end of the wind cover. There is an oil cup to cover the oil leakage. Most of the existing range hoods have a single-layer structure. If the mesh of the fan cover is too large, although it can ensure good suction, the oil fume filtering effect is not good and the oil will accumulate. It will drip directly from the mesh to the cooktop, and if the mesh is too small, good suction cannot be guaranteed. [0003] In order to solve the above-mentioned technical problems, a Chinese utility model patent "A Wind Hood Structure of Range Hood" with the patent number ZL200720108960.5 (the announcement number is CN2010376...

AI Technical Summary

Problems solved by technology

As we all know, the oil fume of the double-layer hood structure generally accumulates on the inner surface of the outer hood and the outer surface of the inner hood, and the inner surface of the inner hood is generally not easy to accumulate oil fume, so the hood generally only needs to clean the entire outer hood and the inner hood. The outer surface of the cover is enough, so the process of cleaning the wind cover of the aforementioned patent is relatively complicated
