Abstract

The utility model relates to a gas proof curtain oil fume exhausting machine, in particular to an integral structure combined for cooperating with two air flowing types. The front end of a smoke collecting cover of the oil fume exhausting machine is provided with an equiblast fan, an air filtering screen arranged above the equiblast fan and more than two fences arranged below the equiblast fan. Wind blew out by the equiblast fan can form two tracks gas proof curtains by right of the fences, wherein, one track of gas proof curtain is arranged at the front end and blows basipetally so as to interdict the oil fume waving from the bottom to the top to wave away outwards; the other track of gas proof curtain blows from the top to the inclined backside, and the formed air flow can induce the oil fume to enter a smoke collecting chamber of the oil fume exhausting machine, and then the oil fume is exhausted outdoors through a fan, so the working personnel in a kitchen can be prevented from breathing the oil fume, and the kitchen cleaning is also ensured.

Description

Air curtain type range hood

Technical field

The utility model relates to a kind of air curtain type range hood, be meant two kinds of structures that the air type of flow is combined into one of a kind of cooperation especially, mainly suck aerodynamic ventilation unit and a tool is sent aerodynamic ventilation unit in conjunction with forming a ventilation equipment device person by a tool.

Background technology

The cooking method of Chinese dishes is always liked steaming, boils, fries fried, therefore can produce a large amount of oil smoke, steam, and fill the air indoor for fear of oil smoke, therefore, smoke exhaust nearly all can be installed in the kitchen by each family, be illustrated in figure 2 as the organigram of general smoke exhaust, general smoke exhaust is to adopt the induction type venting principleand oil smoke to be drained into outdoor, utilize the mode of a large amount of exhausting (gas), by exhaust fume collecting hood 50 oil smoke is concentrated in the cover, utilize ventilating fan 51 that the oil smoke in the exhaust fume collecting hood 50 is sucked bellows 52 again, drain into outdoor by smoke evacuation air outlet 53.

Yet existing smoke exhaust but has following disappearance:

1. obstruct the view for avoiding, the setting of general smoke exhaust all is installed in the height above eyes, and the oil smoke of Yin Gaowen generation can suck cooker earlier through remarkable face before reaching exhaust fume collecting hood 50 thus, influences the health of respiratory apparatus.

2. because exhaust fume collecting hood 50 is too high, also have a segment distance to bowl, make oil smoke easily, promptly fly away out, not only endanger kitchen staff's respiratory apparatus, also make kitchen tools that oil smoke attaches, wall and be difficult to clean also not arriving before the exhaust fume collecting hood 50.

Summary of the invention

Because the various shortcoming of existing smoke exhaust, utility model designer of the present utility model promptly studies intensively, and hopes to reach and reduces oil smoke smoke exhaust elegant and that sucked by human body everywhere.

In order to achieve the above object, major technique of the present utility model is to provide a kind of air curtain type range hood, it comprises a casing, a ventilating fan, described casing comprises that bellows, are located at the exhaust fume collecting hood that the fume collecting chamber of bellows front side, is extended by bellows and fume collecting chamber top forward, described ventilating fan is located on the perisporium of bellows front side, and bellows front side perisporium is corresponding at the ventilating fan place, is provided with a upper end suction inlet, it is characterized in that:

The front side perisporium of fume collecting chamber is provided with a lower end suction inlet that is positioned at suction inlet below, upper end;

Be provided with a blowing fan at the exhaust fume collecting hood front end in addition, the blowing fan below is provided with plural fence.

Implement after the above-mentioned technological means, the obtainable concrete benefit of the utility model is:

Because the utility model is provided with the lower end suction inlet below the suction inlet of upper end, and on exhaust fume collecting hood, be provided with blowing fan and fence, being positioned at the wind that the fence of front end can blow out blowing fan down guides, and the fence of the described side of close fume collecting chamber is that the wind guiding is blowed to the lower end suction inlet, therefore, when oil smoke is up waftd when rising by the below, the wind that blowing fan produced can produce two road gas curtains via fence, wherein one gas curtain can be blocked oil smoke and up fly away, another road gas curtain is then brought into play inducing action, oil smoke via being attracted by the gas curtain that flows, is entered in the fume collecting chamber via the lower end suction inlet, discharge outdoor via ventilating fan again.

So the utility model can reach really and prevent that the kitchen staff from sucking oil smoke, and the purpose that keeps kitchen cleaning.

The specific embodiment

For making your juror further understanding and understanding be arranged to the architectural feature and the function of the described air curtain type range hood of this case, now lift a possible embodiments and cooperate shown in Figure 1 being described in detail as follows, in the middle of the following again explanation, so-called " front side " is meant the side towards the stove fire of culinary art:

It is to comprise that the utility model provides the air curtain type induced-draft fan:

One casing 1, described casing 1 comprises that bellows 10, are located at the exhaust fume collecting hood 15 that the fume collecting chamber 13 in bellows 10 the place aheads, is extended by bellows 10 and fume collecting chamber 13 tops forward, described bellows 10 top perisporiums are provided with a smoke evacuation air outlet 11, and fume collecting chamber's 13 front side perisporiums are provided with a upper end suction inlet 130, and a lower end suction inlet 131 that is positioned at suction inlet 130 belows, upper end, be provided with a draw-off tray 133 in fume collecting chamber 13 bottoms in addition;

One ventilating fan 20 is mounted on the front side perisporium of bellows 10, and is correspondingly positioned at upper end suction inlet 130, and ventilating fan 20 has a suction inlet 21 towards cooking position, and an oil-collecting net 25 is installed on suction inlet 21;

One blowing fan 40, be provided in a side of exhaust fume collecting hood 15 front ends top, be provided with a guiding type air outlet 150 that is positioned at below the blowing fan 40 on the exhaust fume collecting hood 15, the two groups of fence 151 that can adjust the air-out angle are set on described guiding type air outlet 150, one group of angle of sending gas curtain with convenient adjustment blowing fan 40, with really will be by the correct introducing lower end suction inlet 131 of the oil smoke that rises in the below, via ventilating fan 20 oil smoke is drawn in the bellows 10 again, discharged by smoke evacuation air outlet 11, the oil smoke that relies on upper end suction inlet 130 will remain in the exhaust fume collecting hood 15 is in addition discharged again; And one group of fence 151 can form the air of blowing fan 40 submitting portions one air-curtain type gas curtain and stops the oil smoke that flies away that partly rises to release.

Above blowing fan 40, be provided with an air inlet in addition, and extraneous air sucks, be preferably an airstrainer 41 is set on air inlet, can guarantee that the air of a clean no oil smoke sent by blowing fan 40, with formation one gas curtain from top to bottom between staff's oil smoke district, can prevent really that the staff from sucking oil smoke.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present utility model.
