Abstract
The invention discloses an oil screen device of a range hood, which takes the side far away from the interior of the range hood as the outer side. The oil screen device of the range hood comprises a layer of outer layer filter plate and at least one layer of inner layer filter plate, wherein the inner layer filter plate and the outer layer filter plate are both provided with a perforating vent, the vents on two adjacent layers of filter plates are arranged in a mutual staggering way, a flanging is arranged at the periphery of each vent, the flanging at the periphery of the vent on the outer layer filter plate faces to the interior of the range hood, and the flangings at the periphery of the vents on at least one layer of inner layer filter plate are arranged in the mutual staggering way facing the interior and the exterior of the range hood. The invention combines the advantages of smooth air inlet, little noise, good oil fume filter effect, and the like. When oil fume passes through the surface of the inner layer filter plate and the surface of the outer layer filter plate, grease in the oil fume can be rapidly separated out with good oil fume separation efficiency; and the vents of the inner layer filter plate and the outer layer filter plate are arranged in the mutual staggering way, therefore, oil droplets dripping from the interior of an air duct can be completely received to promote both the performance and the oil dripping resistance of the range hood.
Description
Technical field
The present invention relates to a kind of range hood, particularly a kind of oil screen of smoke exhaust ventilator device.
Background technology
At present, on the market existing oil screen of smoke exhaust ventilator device divide substantially have following several:
First kind is that oil guidance column or oil guide groove add fine and close screen pack type, this kind device is because of adopting fine and close screen pack, in the range hood use, cause mesh to stop up easily, fine and close screen pack is to the Oil Guide poor effect, under the big inadequately situation in oil net angle of inclination, cause greasy dirt directly to drop onto the kitchen range top easily along oily net outer surface;
Second kind is individual layer circle or Long Circle through-hole structure, this kind structure filtering oil smoke weak effect, and do not catch inside, air channel fully, during air channel internal droplets drippage, may pass air vent and directly drop onto the kitchen range top;
The third is double-deck tile type structure, and cranky as double-deck button type oil net air flue, the air intake resistance is very big during airflow passes oil net, and air-flow very has some setbacks, and produces a lot of eddy current, and noise is very big, and air quantity also can't promote;
The 4th kind is bilayer " U " shape structure in the same way, though this structure air intake is smooth and easy, and this structure oil smoke inferior separating effect, oil smoke directly is inhaled in the blower fan, influences blower fan service life.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of oil screen of smoke exhaust ventilator device, this oil screen of smoke exhaust ventilator device can effectively filter oil smoke, have both the smooth and easy advantage of air intake again, can reduce noise, improve air quantity, double-deck simultaneously dislocation can be caught the oil droplet in the air channel again fully.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of oil screen of smoke exhaust ventilator device, with the side away from range hood inside is the outside, comprise one deck outer filter plate and one deck internal layer filter at least, in, be equipped with the air vent that runs through on the outer filter plate, air vent on the adjacent two layers filter is mutual dislocation and arranges, the air vent periphery is provided with flange, the flange of air vent periphery is towards range hood inside on the outer filter plate, at least the flange direction of air vent periphery is towards range hood is inside and outside and is staggered on one deck internal layer filter, it is smooth and easy that this kind structure has both air intake, noise is little, the advantage of oil smoke good separating effect, double-deck misconstruction can be caught the oil droplet of the inner drippage in air channel fully.
As step improvement of the present invention, the flange direction of air vent periphery is towards inside and outside staggered being spaced of range hood on the described internal layer of one deck at least filter.
As step improvement of the present invention, described internal layer filter is one deck.
Improving as a step of the present invention, is benchmark with the installation direction, and being shaped as of described outer filter plate and internal layer filter is truncated cone-shaped, a kind of in circular arc and the flat board.
As step improvement of the present invention, be benchmark with the installation direction, described outer filter plate and internal layer filter bottom are respectively equipped with outer, interior oil leaking hole.
As step improvement of the present invention, be provided with the air intake gap between described internal layer filter and outer filter plate.
Improve as a step of the present invention, air vent be at least a in circle, strip and the polygon on the described inside and outside layer filter.
As step improvement of the present invention, the flange and the entity coupling part of air vent periphery are provided with fillet on the described inside and outside layer filter, and the entity part of inside and outside like this layer filter is rendered as arc structure, and the oil smoke air intake is smooth and easy.
As step improvement of the present invention, be provided with the air intake gap between each internal layer filter.
Improve as a step of the present invention, described inside and outside filter is a kind of in metal and the plastic material.
The invention has the beneficial effects as follows: in of the present invention, the entity part of outer filter plate is rendered as arc structure, again at least on the described internal layer filter of one deck the flange direction of air vent periphery towards the inside and outside arrangement of range hood, to have both air intake smooth and easy for lampblack absorber like this, advantages such as the little and filtering oil smoke of noise is effective, in the oil smoke warp, during outer filter plate surface, grease can be separated fast in the oil smoke, the oil smoke good separating effect, in, the air vent of outer filter plate is staggered, can catch the oil droplet of the inner drippage in air channel fully, lampblack absorber performance and antidrip oiliness are all had lifting.
