Abstract

The utility model discloses a novel oil net, wherein an outer oil net is positioned at the outer side of an inner oil net; the inner oil net and the outer oil net are respectively provided with a first vent hole and a second vent hole; one side wall of the first vent hole is provided with a first turnup which has a center inclined angle relative to the first vent hole; the second vent hole is internally and peripherally provided with a sealing and annular second turnup which is faced to the direction of the inner oil net; the first vent hole and the first turnup corresponding thereto are properly and completely covered right above the second vent hole and the second turnup corresponding thereto; and the lower end of the first turnup is properly positioned between the two adjoining turnups corresponding to the outer oil net. The novel oil net leads the streamline of air flow to be smooth during flowing, has small air quantity lose, hardly forms into vortex when the air flow penetrates through the inner oil net and the outer oil net, has low noise, leads the oil smoke to have good filtration effect since the oil smoke is filtered by means of surface filtration and the gas can meet the inner oil net and the outer oil net with larger area during moving, and leads the oil drops to be capable of smoothly flowing into an oil-collecting cup since the inner oil net and the outer oil net have a certain angle relative to the horizontal plane.

Description

Novel oily net

Technical field

The utility model 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 utility model provides a kind of novel oily net, and this novel oily net Oil Guide performance is strong, and effective to filtering oil smoke, noise is low.

The utility model 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 further improvement of the utility model, oily outward net one side of first flange (turning over downwards) on described first air vent, one sidewall.

As further improvement of the utility model, outer dorsad oily net one side (upwards turning over) of first flange on described first air vent, one sidewall.

As further improvement of the utility model, 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 further improvement of the utility model, described inside and outside oily net is the plate shaped of coupling mutually.

As further improvement of the utility model, 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 further improvement of the utility model, first flange of first air vent of interior oil net is curved along the cross section of its incline direction, in linear pattern and linear and the arc-shaped transition syndeton any one.

As further improvement of the utility model, 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 further improvement of the utility model, 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 further improvement of the utility model, 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 utility model is: the utility model cooperates by inside and outside oil net, and the turnup structure of first and second air vent that inside and outside oil is online makes that the streamline of air-flow in flow process is smooth and easy, do 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 utility model 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.
