Abstract

The invention discloses a filtering device for a range hood. The filtering device comprises a first-layer screen plate, a second-layer screen plate and a third-layer screen plate which are sequentially arranged from bottom to top in a spaced manner, wherein the first-layer screen plate comprises a plurality of first bulges, which are arranged left and right in a spaced manner, and a plurality of first recesses, which are arranged left and right in a spaced manner, and a first mesh is formed in each first bulge; the second-layer screen plate comprises a plurality of second bulges, which are arranged left and right in a spaced manner, and a plurality of second recesses, which are arranged left and right in a spaced manner, a second mesh is formed in each second bulge, and a third mesh is formed in each second recess; the third-layer screen plate comprises a plurality of third bulges, which are arranged left and right in a spaced manner, and a plurality of third recesses, which are arranged left and right in a spaced manner, and a fourth mesh is formed in each third recess; and positive projections of the first-layer screen plate, the second-layer screen plate and the third-layer screen plate on the same horizontal plane all have overlapped portions at joints and are gapless.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter device for a 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 ...
