Description

Screen pack and range hood
Technical field
The present invention relates to kitchen utensils field, more specifically, relate to a kind of screen pack and the range hood comprising this screen pack.
Background technology
The screen pack of range hood is installed on the air inlet of range hood, it is one of core component of range hood, its technical development simply filters cigarette and Oil Guide from initial employing single layer filter net, develop into and adopt now double-layer staggered screen pack to carry out the filter cigarette of enhancement, secondly, existing cold plate also can replace screen pack to realize the function of filter cigarette and Oil Guide.
The main function adopting following two schemes to realize filtering cigarette and Oil Guide in prior art, one adopts cold plate structure, and it is arranged on the air inlet of range hood, plays condensation oil smoke and cold oil is imported the effect of lubricating cup; Another kind is the screen pack adopting double-H groove weld web frame, when making oil smoke by this double-H groove weld net, is separated oil smoke by the collision between oil smoke and the sheet metal component of range hood.But, adopt the mode of cold plate structure, effectively can not guide air-flow, make the air-flow of the air inlet of range hood confusion, wind speed little, and easily cause internal body to produce sinuous flow and noise; Adopt the mode of double-H groove weld web frame, make the complex structure of screen pack, clean difficulty.
Summary of the invention
The present invention is intended at least to solve one of technical problem existed in prior art.
For this reason, the object of one aspect of the present invention is, provides one effectively can separate rectification to air-flow, and then can reduce the screen pack of noise in body.
