Abstract
The utility model relates to a cooking fume extractor for suction of cooking fumes of household stoves. The utility model is composed of a centrifugal fan 1, a nozzle 2, an ejector 3, a cooking fume hood 4, an air curtain 5 and a fume exhaust pipe 6, and is characterized in that the centrifugal fan 1 is arranged on the top side part of the cooking fume hood 4; an air outlet of the centrifugal fan is connected with the angle pipe shaped nozzle 2 which is upward inserted in the ejector 3; the lower side part of the nozzle 2 is provided with a smaller air outlet connected with a wind inlet of the air curtain 5. The utility model can directly exhaust the cooking fumes out of a room through the ejector 3 and the fume exhaust pipe 6 by utilizing the high-velocity airflow of the centrifugal fan to form negative pressure in the cooking fume hood 4, and the cooking fumes do not pass through the centrifugal fan.
Description
The utility model relates to a kind of smoke exhaust ventilator that aspirates family's range fume.
In technique known, the smoke exhaust ventilator that family's cooking stove is used, oil smoke all will discharge through blower fan inside, therefore, stick to the grease of impeller and lampblack absorber inner chamber, are difficult to cleaning.
The purpose of this utility model provides not cleaning fan of sucking oil fume of a kind of injecting type, and this machine utilizes principle of negative pressure, and oil smoke is without blower fan, but the jet that utilizes blower fan to produce is directly discharged oil smoke outdoor from oil smoke cover.
Realize that the scheme that the purpose of this utility model is taked is: this machine is made up of centrifugal blower, nozzle, oil smoke cover, ejector, smoke exhaust pipe and air curtain.Centrifugal blower is fixed on the top of oil smoke cover, and nozzle is equipped with at its place, gas outlet, and the Taper Pipe that its inner chamber is a convergent is located in the gas outlet of nozzle, be directed upwardly, and insertion is contained in the ejector that is positioned at the oil smoke cover top.The lower end of ejector is a Taper Pipe, and upper end straight tube and smoke exhaust pipe join, and smoke exhaust pipe passes to outdoor.After starting blower fan, air enters centrifugal blower, boost the back by the nozzle ejection that is contained in its place, gas outlet, accelerate at the nozzle exit velocity, pressure descends, form negative pressure, thereby make the gas pressure in the oil smoke cover be lower than atmospheric pressure, oil smoke is risen by oil smoke cover under the atmospheric pressure effect, and enters ejector with the gas by the nozzle ejection, in ejector, two kinds of different air-flows carry out power conversion and mixing, make oil smoke have certain kinetic energy at last, travel forward, discharge outdoor by smoke exhaust pipe with air.
In order to prevent that oil smoke from overflowing outside the cover from the oil smoke cover door, on the top of oil smoke cover door air curtain is housed, the air source of air curtain is from centrifugal blower.
The smoke exhaust ventilator that adopts such scheme to make, oil smoke is only through oil smoke cover and ejector, without centrifugal blower, the oil smoke cover inner chamber is simply smooth in addition, and the surface cannot not be coated with stickingly the light wood material, and it is convenient especially to clean, and be easy to clean out, reduced the worries of people's cleaning fan of sucking oil fume grease.
Utilize accompanying drawing to further describe embodiment of the present utility model below.
Fig. 1 is a structural representation of the present utility model:
Be contained in the top side portion of oil smoke cover 4 with reference to figure 1. centrifugal blowers 1, nozzle 2 is equipped with in its gas outlet, nozzle 2 is an elbow-shaped, its gas outlet inner chamber is the Taper Pipe of a convergent, the Taper Pipe mouth up, and insert in the Taper Pipe of ejector 3 bottoms, the following side of nozzle 2 also is provided with a less gas outlet, is connected with the air inlet of air curtain.Ejector 3 is positioned at the top of oil smoke cover 4, adopts the lower end Taper Pipe, the structure of upper end straight tube, and the straight tube on top is connected with smoke exhaust pipe 6.After starting centrifugal blower 1, the air of no oil smoke is inhaled into centrifugal blower 1, and the most of gas in back that boosts is by nozzle 2 ejections, and in the exit velocity increasing of nozzle 2, pressure descends, and forms negative pressure.Make the gas pressure in the oil smoke cover 4 be lower than atmospheric pressure from face, oil smoke is under the atmospheric pressure effect, enter ejector 3 through oil smoke cover 4 risings with the gas that nozzle 2 sprays, in ejector 3, constantly carry out power conversion, make oil smoke have certain kinetic energy and travel forward, after smoke exhaust pipe 6 discharges are outdoor.Simultaneously, the air that comes out from nozzle downside gas outlet enters air curtain 5, oil smoke cover 4 the door on form air curtain, with the resistance when oil smoke excessive from the doorway of oil smoke cover 4.
