Abstract
The utility model provides an oil fume exhaust fan. The fan is isolated from a fume flow, and originally using the fan to draft air to remove fume is changed into using the fan to blow to remove fume, so that the fan is not stuck and polluted by the oil fume any longer. The fan and the fume flow are separated in two different cavities, the fan absorbs air from the top of a fume collecting hood, the strong air flow is blown out from an air exhaust port to a fume exhaust port, negative pressure is generated in the hood, and the absorbed fume is blown outdoors along with an air flow to achieve the effect on removing fume. Besides, a range hood is very easy to clean.
Description
The utility model belongs to ventilation equipment, is specifically related to a kind of smoke exhaust.
Existing smoke exhaust miscellaneous all is that the motor drives fan runs up and produces upwards draft, discharges flue gas outdoor in fan sucks the oil extraction hood again.Fan directly contacts with the oil smoke air-flow in the process that oil smoke is discharged, and has greasy dirt on the fan fan page or leaf and adheres to.Though having the part greasy dirt to be rotated at a high speed by fan dishes out, concentrate a place to outwell through oil extraction hood inwall, can still there be oil to remain on fan page or leaf and the hood inwall, increases with the increase of service time, when greasy dirt amasss to the smoke discharging effect that to a certain degree will have influence on fan.And, very difficult in the cleaning of greasy dirt, also be difficult for cleaning up.
The purpose of this utility model provides a kind of: fan no longer directly contacts the smoke exhaust that fan is not adhered to by greasy dirt with flue gas stream.
This smoke exhaust comprises: exhaust fume collecting hood, motor, fan, the following of exhaust fume collecting hood opens wide, there is exhaust opening the behind of exhaust fume collecting hood, the front of this cover and both sides lower limb are distributed with the air curtain hole, and motor mounting is on exhaust fume collecting hood top, and fan is installed on the motor reel, it is characterized in that: exhaust fume collecting hood is made up of shell and inner casing, the cavity that forms is at interval arranged between the front of this cover and the inner casing of both sides and the shell, and fan has on the cavity with the corresponding position of exhaust opening exhaust outlet is arranged in this cavity.
The exhaust fume collecting hood lower limb of above-mentioned smoke exhaust is furnished with the air curtain hole, and it has the air curtain pipe to stretch out downwards, and the mouth of pipe is a rectangle or oblate.
The operation principle of this smoke exhaust is: the motor drives fan is blown into the exhaust fume collecting hood inner casing with air-flow from exhaust outlet, blows out from exhaust opening; Air-flow is taken away most of air formation negative pressure generation suction in the exhaust fume collecting hood, and suction is gone into exhaust fume collecting hood with the oil smoke aspiration and discharged the open air again with the air-flow that fan is blown into, and reaches the effect of mist extractor.
Said fans can produce the air-flow that scatters simultaneously blowing out air-flow to exhaust outlet, is assembled downwards by the ventilating layer between the inside and outside shell of exhaust fume collecting hood, discharges from the air curtain hole and forms air curtain.Air curtain can stop oil smoke and hot gas upwards to scatter, so that better realize smoke discharging effect.
Because this smoke exhaust fan is placed in the cavity between the inside and outside housing of exhaust fume collecting hood, no longer directly contact with oil smoke, oil can its surface of pickup, and the inner casing of exhaust fume collecting hood does not also just have the oil of being dished out by fan and does not adhere to.Fan has kept cleaning, and the cleaning of inner casing is also very convenient.
The motor of this smoke exhaust can be installed in the top or the positive top of smoke exhaust.
Now doing one in conjunction with the accompanying drawing of smoke exhaust embodiment understands:
Fig. 1 is the cut-away view of smoke exhaust embodiment one.
Fig. 2 is the horizontal cut-away view of the lower limb of smoke exhaust embodiment one.
Fig. 3 is the cut-away view of smoke exhaust embodiment two.
Smoke exhaust embodiment one comprises exhaust fume collecting hood, exhaust opening 3, motor 5, fan 7 compositions.The trumpet-shaped bottom of exhaust fume collecting hood is for opening wide, and there is exhaust opening 3 behind of exhaust fume collecting hood, and the front of this cover and both sides lower limb are distributed with air curtain hole 8.Exhaust fume collecting hood is made up of the crust of weathering 2, shell 1, shell 1 and inner casing 2 have between the front of this cover and both sides at interval and the ventilating layer 4 that forms, form cavity 6 between the front of this cover inner casing 2 and shell 1, fan 7 is installed with the axle of the motor of installing in the front upper of exhaust fume collecting hood 5 in cavity 6.Have on the cavity 6 with the corresponding position of exhaust opening and have exhaust outlet 10.Cavity 6 connects with ventilating layer 4, air curtain hole 8, and the air curtain pipe 9 that stretches out is downwards arranged on the air curtain hole 8, and the mouth of pipe be an oblateness, on the shell 1 of a side of fan 7 air inlet is arranged.
The method of work of present embodiment is as follows: motor 5 drive fans 7 high speeds are rotated, and produce the strength air-flow that blows out to exhaust outlet 10 and move and the discharge open air to exhaust opening 3 at a high speed, produce negative pressure in the exhaust fume collecting hood, with the oil smoke suction and the discharge open air of required discharge; Fan 7 to around the strength air-flow assembled downwards through ventilating layer 4, discharge downwards from air curtain pipe 9 again and form air curtains and stop flue gases to scatter.
Claims (2)
1, smoke exhaust, it comprises exhaust fume collecting hood, motor, fan, the bottom of exhaust fume collecting hood is for opening wide, there is exhaust opening the behind of exhaust fume collecting hood, the front of this cover and both sides lower limb are distributed with the air curtain mouth, and the top of exhaust fume collecting hood is equipped with motor, and fan is installed on the motor reel, it is characterized in that: exhaust fume collecting hood is made up of shell and inner casing, has between the front of this cover and the inner casing of both sides and the shell to form ventilating layer at interval; Form cavity between the top inner in front, shell, fan is installed in this chamber, has the correspondence position with exhaust opening that exhaust outlet is arranged on the cavity.
2, smoke exhaust as claimed in claim 1 is characterized in that: above-mentioned air curtain hole is to be inserted with the air curtain pipe that stretches out downwards, and the mouth of pipe is rectangle or oblateness.
