Abstract
The utility model relates to a fume and smoke filter in a plane structure formed by front and back plates with spacing with each other. The fume and smoke inlet on the front plate and the air outlet on the back plate are all the bar-shaped holes with section in ladder, and the fume and smoke inlet and the air outlet are in crossed arrangement. The fume and smoke filter forms a plurality of channels making air flowing sudden turning, which is beneficial for the separating of fume and smoke to reach high-efficient fume and smoke separating effect. The utility model is of easy manufacturing and low cost, which is applicable for different exhaust hood.
Description
Technical field
The utility model relates to a kind of filter, particularly relates to a kind of cooking fume filter.
Background technology
Culinary art is indispensable vitals with cooking fume filter in the smoke exhaust ventilator, because its effect is the oil smoke in the separation of air, promptly separates tiny oil droplets, therefore directly influences the result of use of smoke exhaust ventilator.In the prior art, the structure of cooking fume filter is, cuts many mouthfuls on aluminium foil, by hand it pulled into irregular hole then, adds on the two sides of aluminium foil that again the aluminium net forms.Its objective is that formation is streamed, vortex, when making this filter of air process of the oil smoke of carrying under one's arms, heat is absorbed by aluminium foil, and oil smoke is that tiny oil droplets becomes liquid, separates from air, reaches the purpose of separating oil smoke.But owing to can only adopt and make by hand, hole big or small irregular and inhomogeneous caused the service behaviour instability, and quality can not guarantee, cost height, also inconvenience cleaning.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and cost is low, but the mechanization one-shot forming, and the cooking fume filter of good separating effect.
The utility model cooking fume filter is to realize like this, it is a slab construction, form by forward and backward two, certain intervals is arranged therebetween, oil smoke import on the anter and the air outlet slit on the rear panel all are that cross section is trapezoidal bar hole, adopt the punching press one-shot forming, and oil smoke import and air outlet slit are staggered.This structure has constituted the passage that makes air flow and turn back suddenly, forms air and streams and vortex, and flow air is when flowing to variation suddenly, because the effect of inertia force, the oil smoke of being carried under one's arms in the air (tiny oil droplets) is pulled out away from.Simultaneously,, through sharp keen edge the time, produce the vortex that flows around air flowing because oil smoke import and air outlet slit edge are sharp keen, the same because effect of inertia force, tiny oil droplets is pulled out away from, and finishes filtering oil smoke.
The operation principle of the utility model cooking fume filter is, be installed in the air inlet place of smoke exhaust ventilator during use, because the effect of motor, wind wheel and spiral case in the smoke exhaust ventilator, the air of the oil smoke of carrying under one's arms is sucked from air inlet, enter, produce and stream and vortex by the oil smoke import, making oil smoke is that tiny oil droplets is pulled out away from out from air, flow in the oil sump tank in the smoke exhaust ventilator, the air of removing behind the oil smoke flows out from air outlet slit, reaches and filters the oil smoke purpose.
The advantage of the utility model cooking fume filter is simple in structure, the mechanization one-shot forming, and cost is low, stable performance, the oil smoke good separating effect, the separative efficiency height is applicable to various smoke exhaust ventilators.
