Abstract

The invention discloses a novel oil screen. An outer oil screen is positioned outside an inner oil screen; the inner oil screen and the outer oil screen are provided with first ventilation holes and second ventilation holes respectively; a side wall of each first ventilation hole is provided with a first turned edge which forms a set included angle with the first ventilation hole; the inner periphery of each second ventilation hole is provided with a second turned edge which faces the inner oil screen and has a closed ring shape; the first ventilation holes and the first turned edges corresponding to the first ventilation holes completely cover just above the second ventilation holes and the second turned edges corresponding to the second ventilation holes; and the lower end of each first turned edge is just positioned between two adjacent second turned edges corresponding to the outer oil screen. Through the novel oil screen, air flow has a smooth flow line during flowing, and the loss of air quantity is small; the air flow hardly forms eddy current when passing through the inner oil screen and the outer oil screen, so the noise is low; the oil smoke is mainly processed by a surface filtration method, so the gas can contact larger areas of the inner oil screen and the outer oil screen during movement to achieve a good oil smoke filtering effect; and since both the inner oil screen and the outer oil screen are at a certain angle with the horizontal plane, oil drops can smoothly flow into an oil collection cup.

Description

Novel oily net
Technical field
The present invention relates to a kind of used for range hood oil net, particularly a kind of novel oily net.
Background technology
Existing oil screen of smoke exhaust ventilator generally all is one deck structure, all can have following some deficiency basically:
1) oily net Oil Guide poor performance, the meeting leakage of oil;
2) after range hood was loaded onto the oil net, noise can obviously increase;
3) oily net is bad to the filtering oil smoke effect;
4) after range hood was loaded onto the oil net, wind loss was very big.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of novel oily net, this novel oily net Oil Guide performance is strong, and effective to filtering oil smoke, noise is low.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of novel oily net, oily net and outer oily net in comprising, to use direction to be benchmark, outer oily net is positioned at the oil net outside (away from range hood inside one side), in, outer oil is respectively equipped with first on the net, two air vents, first air vent, one sidewall is provided with this first air vent and is first flange of setting angle, the second air vent inner rim is provided with second flange that is closed circular towards interior oily net direction, first air vent and the first corresponding flange thereof be covered in just fully second air vent and corresponding second flange thereof directly over, the first flange low side just outside between corresponding adjacent two second flange of oil net, during use, oil smoke along second air vent of outer oil net by the suction band of range hood and is made progress away, in it is gone to during the first air vent place of oil net, run into below first flange, form little oil droplet owing to meet condensation, oil was netted between adjacent two second flange outside its first flange along interior oily net first air vent was slipped to downwards, little oil droplet just can glide along the passage between adjacent two second flange of outer oil net and flow in the catchment cup this moment, because first flange of interior oil net just in time covers second air vent of outer oil net, oily net in the little oil droplet that oil smoke forms can not pass, make oil smoke can not pollute range hood inside, filtering oil smoke is effective, again because in, outer oil is netted corresponding mutually and turnup structure is all arranged, air-flow linearly flows in flow process, it flows and smooth and easyly can not stopped, the little eddy current that also do not form of wind loss, its noise is just very low like this.
As a further improvement on the present invention, oily outward net one side of first flange (turning over downwards) on described first air vent, one sidewall.
As a further improvement on the present invention, outer dorsad oily net one side (upwards turning over) of first flange on described first air vent, one sidewall.
As a further improvement on the present invention, described inside and outside oily net is the truncation rectangular pyramid shape of mating mutually, and described first and second air vent all is positioned on the sloped sidewall of truncation rectangular pyramid.
As a further improvement on the present invention, described inside and outside oily net is the plate shaped of coupling mutually.
As a further improvement on the present invention, concave arc surface connects under passing through between second flange that is parallel to each other of adjacent two second air vents of described outer oil net, and convenient little oil droplet flows downward.
As a further improvement on the present invention, any one in first flange of first air vent of interior oil net, linear pattern curved and linear and the arc-shaped transition syndeton along the cross section of its incline direction.
As a further improvement on the present invention, first and second air vent of described inside and outside oil net all is strip, and first flange is positioned at the long limit of first air vent one side.
As a further improvement on the present invention, the gap between inside and outside oil net is 0 to 20mm; First and second air vent width of inside and outside oil net is 2~30mm.
As a further improvement on the present invention, after inside and outside oily net was fixed on the range hood, first and second plane, air vent place was horizontal by setting angle, and convenient little oil droplet flows downward.
Useful technique effect of the present invention is: the present invention cooperates by inside and outside oil net, and the turnup structure of online first and second air vent of inside and outside oil makes that the streamline of air-flow in flow process is smooth and easy, is not stopped that almost its wind loss is very little; Air-flow is in passing inside and outside oily network process simultaneously, form eddy current hardly, make its noise very low, oil smoke of the present invention mainly is the mode by surface filtration, gas is in motion process, can run into the inside and outside oily net of larger area, make filtering oil smoke effective, in vertical direction, first flange of interior oily net air vent just in time covers outer oily net air vent, oily net in the oil dripping that oil smoke forms can not pass because inside and outside oil net is all angled with horizontal plane, makes oil droplet to flow in the catchment cup smoothly again.
