Abstract

The utility model relates to an air curtain type cooking fume exhauster which comprises an electric machine 8, a wind casing 14 and fans 3, wherein, a through shaft 7 of the electric machine 8 is provided with a positive fan 3 and a reverse fan 6 which rotates in the same direction rotation, but can are reversely arranged; an air curtain channel 15 is formed between a wind guide ring 1 and a wind collecting hood 5. The formed air curtain can cause the sucking and exhausting effect to be increased and kitchens to be prevented from being soiled. The cooperation of a support rod 10 and a support frame 9 can freely regulate corresponding positions and angles of the cooking fume exhauster.

Description

Air curtain type fume exhaustor

The utility model relates to a kind of smoke exhaust ventilator, belongs to cooking apparatus.

Existing smoke exhaust ventilator is divided into two kinds of straight-line and side-types.Because its structure limits, the suction effect that is produced is also not very good, and sharply the oil smoke that spreads exceeds the negative pressure suction district, also has oil fume outer-runaway, phenomenon such as dirty, and why Here it is is equipped with the reason place that the kitchen of smoke exhaust ventilator also can be dirty.A kind of smoke exhaust ventilator that has air curtain is arranged, and is to have elongated slot on three frames of smoke exhaust ventilator, and the negative pressure that is produced by fan rotation produces air curtain and near the air the elongated slot is sucked.But the air curtain that this structure produced is very not obvious, and effect is also relatively poor, can not really play the effect of air curtain.

The purpose of this utility model is exactly for overcoming the deficiency described in the background technology, and a kind of air curtain than strong wind, air curtain type fume exhaustor that suction effect is good of producing is provided.

To achieve these goals, the utility model proposes the corresponding techniques solution:

This air curtain type fume exhaustor comprises motor, the crust of weathering and fan, and it mainly is to be respectively equipped with forward fan and reverse fan at the axis two ends of motor, and air-ducting ring and wind gathering cover lower edge constitute an air curtain passage.The spiral shell shelly crust of weathering is positioned at wind gathering cover, and its exhaust outlet exceeds the wind gathering cover outer wall.Air-ducting ring is fixed by the screw and the crust of weathering.Be connected with support after the fixing pole of motor passes wind gathering cover.On the oil guide groove of air-ducting ring inner circle, be provided with the Oil Guide web plate.

Accompanying drawing is a structural representation of the present utility model.

As shown in drawings, the utlity model has a wind gathering cover 5, motor 8 is positioned at wind gathering cover 5.Upper and lower end at the axis 7 of motor 8 does not have reverse fan 6 and forward fan 3 respectively, and the direction of rotation of these two fans is identical, but the angle of fan installs on the contrary, i.e. forward fan 3 forward air drafts, and oppositely fan 6 oppositely aspirates.The crust of weathering 14 of similar snail shell also is positioned at wind gathering cover 5, but forms an air channel with the inwall of wind gathering cover 5, and its exhaust outlet 13 exposes outside the wind gathering cover 14.A uncovered trumpet-shaped air-ducting ring 1 is connected with the crust of weathering 14 by screw 2, and constitutes an air curtain passage 15 with the bottom of wind gathering cover 14.Stretch out outside the wind gathering cover 5 with the pole 10 that motor 8 is fixed, and be connected and fixed with support 9.Also be provided with a curved surface Oil Guide web plate 11 that has a mesh at oil guide groove 16 places of air-ducting ring 1 bottom, catchment cup 12 is plugged on the bottom of smoke exhaust ventilator.

This smoke exhaust ventilator is when work, and motor 8 drives forward fan 3 by axis 7 and reverse fan 6 rotates in the same way.At this moment, the negative pressure that forward fan 3 produces is pumped in the oil smoke that rises in the crust of weathering 14 by Oil Guide web plate 11, and discharges by exhaust outlet 13; And oppositely fan 6 is pumped to the air in the external world in the wind gathering cover 5, and by discharging by the air curtain passage 15 that forms between the crust of weathering 14 and air-ducting ring 1 and the wind gathering cover 5, so can form air curtain in the periphery of gas kitchen ranges and cooker, and around oil smoke, produce certain air pressure, with the restriction oil fume outer-runaway.Because forward and reverse fan 3,6 is worked simultaneously, so the air pressure that air curtain forms around oil smoke and the draught head at smoke pumping place are bigger, part air on the air curtain also can reflux to the crust of weathering 14 places, oil smoke has been played guide functions, thereby improved the efficient of fume exhaust.The air curtain of ejection can dispel the gas that rises, and the air at smoke exhaust ventilator top is played ringing, also just protective effect has been played at the top, kitchen.Flowing of air also can be played thermolysis to motor 8 in the wind gathering cover 5, also can prolong the service life of motor 8.Simultaneously, wind gathering cover 5 has played buffering to the air of suction again, makes the more even of air curtain distribution.Because air-ducting ring 1 and the crust of weathering 14 are to be regulated fixingly by screw 2, so it can move forward and backward in certain scope, so just can make the part air-flow of air curtain adjusted, thereby make the controlled and utilization of air-flow of the air curtain reflected back that sprays to wall.The Oil Guide web plate 11 of curved surface both can make oil smoke pass through smoothly, residual oil droplet can be flowed into catchment cup 12 along oil guide groove 16 again.This smoke exhaust ventilator can be connected by the pole 10 that links to each other with motor 8 on the support 9 with wall mounted, and tightens with nut after can tune to suitable angle and position, also can adjust its angle and position at any time.

The utility model design concept is relatively unique, adopt the structure of forward and reverse fan and air curtain passage, in fume exhaust, can produce air curtain again, both can improve the suction effect, can avoid dirty kitchen again, its corresponding position and angle of regulated at will as required, the kitchen range room that is fit to very much vast family and enterprises and institutions, unit is installed and used.
