Abstract

The utility model relates to a smoke exhaust ventilator which can prevent the oil smoke from dispersing outwards. It is an improvement of the oil fume extractor. A flat upper suction chamber is arranged on the top of the air chamber of the oil fume exhauster, a motor with bidirectional shaft extension is adopted, and fan blades are respectively arranged on the shaft extension. The wind shield is made into a sandwich form, the wind force in the wind shield blows back the scattered oil smoke which is exhausted by the oil smoke exhauster, the wind shield not only prevents the oil smoke from scattering, but also separates the trouble of hot gas and oil smoke for cooking operators, and the blown wind enables the operators to obtain a comfortable environment.

Description

Cooker hood for preventing from oil fume out

The utility model is a kind of smoke exhaust that prevents that oil smoke from loosing outward, and he is the improvement of existing smoke exhaust.

After the general smoke exhaust that uses adds smoke barrier, can satisfy in normal the use and get rid of the oil smoke needs, but when when cooking moment or oily soup etc. are excessive, producing a large amount of oil smoke, often can not all oil smoke be discharged outdoor, and cause oil smoke to loose outward, and directly attack the operator it is felt hurt, after the diffusing time of oil smoke is permanent, easily cause shortcomings such as indoor appliances, wall, generation grease outward.

The purpose of this utility model is to provide a kind of smoke exhaust that prevents that oil smoke from loosing outward, and it increases one deck air-supply layer on the air compartment of original smoke exhaust body interior, send the oil smoke that looses back to suction/exhaust opening of lampblack exhauster outward with wind-force.Near effectively discharge in the smoke evacuation scope, diffusing and created a comfortable environment except that avoid oil smoke to the operator.

The utility model is realized in the following way, it in range fan shell, on the air compartment top, add system one deck be pancake outside air compartment, to be with twin shaft to stretch the motor setting and be loaded on interior air compartment smoke exhaust smoking port upper end, and shaft extension passes top layer to stretch into exogenous wind indoor on the motor, on upper and lower shaft extension, be respectively charged into fan blade, outer air compartment extends to form the air channel forward along range fan shell, connecting a form to the front side is the angle adjustable of semi-cylindrical bayonet socket pattern and the smoke barrier that has interlayer, and this smoke barrier also can be made into fixedly pattern.Make thin and flat burner mouth that inwardly shrink at the oral area of smoke barrier.

The advantage of this utility model is:

1, cooking, frying, boiling, overflowing when producing a large amount of oil smoke when cooking stove, can will be not do not inhaled by smoke exhaust by the wind that blows out in the active catch aerofoil and go the outer oil smoke that looses to blow to get back to discharge in the smoke exhaust smoking port effective coverage outdoor, it has improved the smoke exhaust smoke exhaust efficiency effectively.

2, the clean air that blows out in the deep bead can make operator and oil smoke hot gas separate and provide one to have wind not have oil smoke, nice and cool, comfortable operating environment for the operator.

Description of drawings

Accompanying drawing 1 is a kind of lampblack exhauster structure and operation principle schematic diagram that prevents that oil smoke from loosing outward

Accompanying drawing 2 is outer air compartment and strap clamp layer sideboard schematic diagram

In conjunction with the accompanying drawings the utility model is described further below by embodiment.

Install one deck on range fan shell top additional and be the thin flat outer wind sucting chamber 5 identical with shell 1 profile, erect the motor 2 that a band of installation twin shaft is stretched in interior wind sucting chamber 6 exhaust openings upper end, and with shaft extension on it pass in air compartment 6 upper walls, stand in the outer air compartment 5,4 fan blade 4 are installed thereon, the fan blade 3 of on 6 times shaft extensions of wind sucting chamber, packing into, back top is shaped on flue 12, be shaped on annular groove around the oil extraction mouth, the aqueous grease of deposition can be flowed in the long-pending oil box 13 by annular groove, on the fan blade top of outer air compartment 5, be shaped on the ventilation circular hole 11 of a plurality of marshallings, air compartment extends to form air channel 8 along range fan shell 1,8 front end is made the semi-cylindrical shape bayonet socket 9 of a projection in the air channel, and the protruding bayonet socket that matches with bayonet socket 9 is also made in deep bead 7 upper ends of strap clamp layer, and it also forms with bayonet socket 9 and to be rotatably assorted.Thin inside closing in form is made at 10 places, air port, deep bead lower end.

Claims

1, a kind ofly prevents smoke exhaust that oil smoke looses outward it is the improvement of smoke exhaust, it is made up of shell, interior wind sucting chamber, flabellum, exhaust opening, long-pending oil box etc., it is characterized in that, on interior wind sucting chamber 6, add the outer wind sucting chamber 5 that one deck is flat, reversing motor 2 is erect and is loaded in the interior wind sucting chamber 5, be respectively charged into fan blade 4 and 3 up and down on the shaft extension, outer wind sucting chamber extends to form air channel 8 along shell front side, protruding semi-cylindrical bayonet socket 9 is made in the end, strap clamp layer deep bead 7 snaps in the bayonet socket 9, and its air port, lower end 10 is flat thin closing in form.

2, by the described a kind of smoke exhaust that prevents that oil smoke from loosing outward of claim 1, it is characterized in that the movable smoke barrier 7 of strap clamp layer also can be made into fixedly smoke barrier form.
