During the work of this kind lampblack absorber, blower fan is directly given from the outside suck air of lampblack absorber and is processed into high velocity air, by the high speed ventilation duct high velocity air is sent to air blown producer then, spray in oil smoke case air inlet by the nozzle on the air blown producer again, in course of injection, be that oil smoke case air inlet place forms low-voltage space, impel the oil smoke in room and other pernicious gases to gather and, discharge through the special-purpose exhaust outlet of oil smoke case then by pressure-vaccum oil-feed smoke box to oil smoke case air inlet place.During lampblack absorber work, if load onto the filtration, purification layer in the oil smoke case, the air-flow in the suction oil-feed smoke box will all obtain filtering and then be discharged from again; If lay down the filtration, purification layer in the oil smoke case, the air-flow that then enters the oil smoke case will directly discharge through exhaust outlet.
Plant the lampblack absorber that technical scheme is made thus, because blower fan is contained in the oil smoke case outside, the two does not directly communicate, and the oil smoke air-flow that enters the oil smoke case can not enter blower fan, so the technical program can fundamentally solve the contaminated difficult problem of blower fan.
In order to make the utility model can form different duties, produce different functions, to handle oil smoke and other pernicious gases effectively and prevent that blower fan is contaminated, the utility model can also be taked more following technical measures:
Be provided with air outlet on the oil smoke case tank wall between oil smoke case and the blower fan, oil smoke case air outlet herein leads to air inlet, and blower fan can be through the gas of the direct inspiration oil smoke of air inlet case air outlet discharge.Special-purpose exhaust ports at the oil smoke case is provided with valve, and the outer blast pipe of special-purpose exhaust outlet and oil smoke case is communicated with.Be provided with fan wind inleting tube at the air inlet place relative, be provided with circulating current inlet, outside air opening and Two purpose valve in the fan wind inleting tube with oil smoke case air outlet.The circulating current inlet directly communicates with the oil smoke case, and outside air opening can be directly from the outside suck air of lampblack absorber.When Two purpose valve pulls open, can allow the interior air-flow of oil smoke case enter blower fan, stop that simultaneously extraneous air-flow enters blower fan; When closing up, Two purpose valve can stop that the air-flow in the oil smoke case enters blower fan, but can make extraneous air-flow enter blower fan simultaneously.In order further to prevent the fume pollution blower fan, be provided with the filtration, purification layer at the oil smoke case air outlet place of leading to air inlet.
Because adopt more above-mentioned technical measures, the utility model can form following three kinds of duties:
1, the periodic duty state, close the valve of the special-purpose exhaust outlet of the utility model oil smoke case, pull open the Two purpose valve in the fan wind inleting tube, energising makes lampblack absorber work, the high velocity air that is quickened by the blower fan running this moment enters air blown producer through the high speed ventilation duct and blows into the oil smoke case, make oil smoke case air inlet place produce negative pressure, attract a large amount of oil smoke air-flows to enter the oil smoke case, and make the oil smoke air-flow that enters the oil smoke case quicken to flow, this moment is because oil smoke air velocity height, penetration capacity is strong, so can pass the filtration, purification layer in the oil smoke case very smoothly, filter oil smoke and other pernicious gas simultaneously, filter after oil smoke and other pernicious gas slow down, enter blower fan again and be processed to high velocity air, advertise and drive the oil smoke air-flow and enter the oil smoke case through air blown producer again, filter oil smoke and other pernicious gases, enter blower fan again and quicken, spray through air blown producer again ... so once and again go on, form the periodic duty state.Filtration, purification oil smoke and other pernicious gases effectively in the periodic duty state, can make blower fan avoid polluting again, simultaneously owing to be filtration, purification oil smoke in circulation canal, there is not oil smoke need discharge lampblack absorber, so whole lampblack absorber need not to be provided with blast pipe, can avoid polluting indoor and outdoor surroundings, this kind duty suits to use under the condition of various rooms, also might as well even use in the study, parlor in the bedroom.
2, half periodic duty state, during lampblack absorber work, open the special-purpose exhaust outlet valve of oil smoke case, making the air-flow part of the oil smoke case of flowing through enter blast pipe through exhaust outlet discharges, a part enters blower fan and is processed into high velocity air and delivers to air blown producer again and spray to drive the oil smoke air-flow and enter the oil smoke case, and an oil smoke air-flow part that enters the oil smoke case discharges through exhaust outlet, and a part enters blower fan and is accelerated, spray through air blown producer, circulation is gone down again.This kind duty produces two kinds of functions of handling oil smoke: full filtration, purification function and direct degassing function, at this moment, if the filtration, purification layer is set in the oil smoke case, the air-flow that then enters the oil smoke case will all obtain filtering, this air that is filtered stream part discharges through exhaust outlet then, and a part enters the blower fan circulation; If take away the filtration, purification layer in the oil smoke case, and leading to the oil smoke case air outlet place installation filtration, purification layer of air inlet, then enter the oil smoke air-flow of oil smoke case without filtration this moment, a part directly is excluded through exhaust outlet, and a part falls through the filtration, purification metafiltration at oil smoke case air outlet place that oil smoke is laggard goes into blower fan and quicken and recycle.
3, acyclic duty, during lampblack absorber work, open the special-purpose exhaust outlet valve on the oil smoke case, close up the Two purpose valve in the fan wind inleting tube, lay down or load onto the filtration, purification layer in the oil smoke case, blower fan inspiration outside air and be processed into high velocity air was sent air blown producer again to and was sprayed and drive the oil smoke air-flow and enter the oil smoke case and directly discharge through exhaust outlet this moment.The oil smoke steam of the excessive overrich of this kind duty suitable treatment.
No matter which kind of duty if load onto the filtration, purification layer at the oil smoke case air outlet place that is communicated with blower fan, can guarantee effectively that blower fan is not contaminated.
Distinguishing feature of the present utility model is to adopt air blast to handle the operation principle of oil smoke.The as easy as rolling off a log oil smoke air-flow that makes of air blast obtains at a high speed, produce stronger penetration power, if adopt circulating or half circulating duty, the oil smoke air-flow that then enters oil smoke case air inlet will both be subjected to the effect of advertising of air blown producer, be subjected to the swabbing action of blower fan again, like this, the speed of oil smoke air-flow can be higher, and penetration power can be bigger.Just because of this, could in the oil smoke case, add multilayer filtering oil smoke purifying layer, filter oil smoke more effectively.
The more important thing is that the utility model is to utilize air blast to produce the effect suction oil smoke of negative pressure, if vertically separate suitable distance between air blown producer and the oil smoke case air inlet, in the work, no matter be direct current air intake or rotation air intake, can make beyond the oil smoke case air inlet, air blown producer forms wide low-voltage space around up and down, is sucked into the oil smoke case again so can impel on a large scale a large amount of oil smoke to crowd into low-voltage space; Hang in the pot for cooking rice both sides and used by accumbency, its air blown producer can directly laterally all blow into the oil smoke case to the oil smoke dregs of fat that pot for cooking rice is emerged again.
Fairly obvious, the utility model adopts air blast to handle the operation principle of oil smoke, to the processing of oil smoke and pernicious gas, and than general smoke exhaust ventilator, no matter on the amount of being, or on the matter, all can be much better.
Purification range hood, owing to be provided with the filtering oil smoke purifying layer, owing to have acyclic, circulation and half periodic duty state characteristic, so, can handle oil smoke effectively during cooking, filtration, purification room air at any time after the cooking.And, no matter be in the cooking or after the cooking, as long as in the oil smoke case filtering oil smoke purifying layer is housed, can guarantee not pollute PE.
Because blower fan of the present utility model is installed in the oil smoke case outside, under the acyclic state, the gas by blower fan, high speed ventilation duct, air blown producer all is again pure air, can prevent that blower fan is contaminated, and oil smoke is handled in air blast, and the filtration, purification ability is strong, the efficient height; And be provided with the filtration, purification layer with the oil smoke case air outlet place of leading to blower fan in the oil smoke case, contaminated these filtration, purification layers are easy to replace cleaning again, this shows that purification range hood both can guarantee that the purified treatment oil smoke was effective, can avoid body inside and outside contaminated again.
