Abstract
The utility model relates to a fume exhausting fan for household kitchens, being composed of a fume exhausting device and a gas cover generating device. When the fume exhausting fan works, the gas cover generating device generates a gas cover to cover fume generated during cooking, limits fume diffusion and centralizes fume to the fume exhausting port so that fume is sucked and discharged within strong suction range. The fume exhausting fan uses one motor and small volume to achieve or exceed the fume exhausting effect of using two motors and big volume and solves the problems of big volume, large power consumption, high cost, etc. existing in fume exhausting fans which use forms of two motors, big volume of a fume exhausting hood, big air exhausting rate, etc. for increasing fume exhausting effect.
Description
The utility model relates to smoke exhaust ventilator, particularly is applied to the smoke exhaust ventilator of family kitchen.
In prior art, family kitchen mainly is made up of exhaust fume collecting hood and blower fan that sheet metal is made with smoke exhaust ventilator.Air-vent is arranged at exhaust fume collecting hood top, and the impeller of blower fan is on air-vent, and blower fan can suck the oil smoke under the exhaust fume collecting hood, discharges outdoor through a segment pipe.For conveniently cooking operation and best performance smoke pumping effect, smoke exhaust ventilator generally is installed on about 80 centimetres high positions, cooking stove top, but in cooking process, when oil smoke arrives this height, understand some from the side to around diffuse into indoor, so this smoke exhaust ventilator is not thorough to the eliminating of oil smoke, in order to improve the lampblack-pumped effect of smoke exhaust ventilator, some smoke exhaust ventilator is equipped with two blower fans, but cost height, take electricity during use, nor can solve the oil smoke interior problem of inlet chamber from the side well.The exhaust fume collecting hood made from sheet metal in addition, volume and weight is all very big, and the surface also need apply, the production cost height.
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and a kind of made of plastic, the work of proposition can produce gas hood, the family kitchen smoke exhaust ventilator that smoke pumping is effective.
The utility model adopts following technical scheme: with driven by motor two covering devices, one is fume exhaust device, and one is the gas hood generator.Two covering devices rotate simultaneously during work, and the gas hood generator blows downwards by annular gas hood mouth, make generation garden platform shape gas hood cover to cooking stove, form shrouding oil smoke.Fume exhaust device can suck the oil smoke in the gas hood and discharge outdoor.
For appearing such scheme suddenly, as fume exhaust device, make fans entrance more slightly larger with a common centrifugal blower than impeller, the mouth smoke pumping impeller of packing into from then on, with jump ring and fixed by nut on motor shaft.The smoke pumping impeller is above fans entrance, and the gas hood impeller is to be evenly equipped with some radial blades on week in the outer garden that the smoke pumping impeller stretches out the garden tube of fans entrance to form.Being provided with ramp structure at the root of blade is that sealing gland is closed device.At the gas hood impeller outer gas hood generator inside and outside shell is arranged, fume exhaust device one side has annular air scoop leaning on into, at opposite side annular oblique air outlet is arranged.During installation, fume exhaust device is last, the gas hood generator be installed in down cooking stove above.During work, the smoke pumping wheel rotation of driven by motor fume exhaust device, the gas hood impeller of gas hood generator also rotates simultaneously.The gas hood generator can blow out a garden platform shape airhood downwards by its annular oblique air outlet.Fume exhaust device can be the oil smoke in the gas hood by sucking in the garden tube of impeller and discharging outdoor.Simultaneously, being arranged on sealing gland on the blade of gas hood impeller closes device and in the mode of gas pressure the garden week gap of oil smoke passage and impeller is sealed.Prevent that the oil smoke in the fume exhaust device from revealing in the gas hood generator.The impeller of smoke exhaust ventilator and shell form with plastic injection-moulded.
The utility model possesses following advantage:
1, economize on electricity, can meet or exceed the effect of two motors, economize on electricity nearly 50 percent with a motor.
2, volume is little in light weight: littler more than 40 percent than present smoke exhaust ventilator volume, weight ratio bi-motor smoke exhaust ventilator light near half.
3, because of adopting overall plastic structure can give the outward appearance of smoke exhaust ventilator novelty; Non-corroding depainting factor; Be convenient to decompose and clean.
4, adopt airhood to form, strengthened the smoke pumping effect the shrouding of oil smoke.
5, owing to adopting injection molding technology production, so the technology simple procedures is few; Few life-span of number of molds is long; Production cost is inefficient high.
Accompanying drawing is a gas cover type smoke exhaust ventilator structural representation, with regard to accompanying drawing the design is described further below:
Among the figure ［ 1 ］ be that motor, ［ 2 ］ oil smoke passage, ［ 3 ］ smoke pumping impeller, ［ 4 ］ gas hood impeller, ［ 5 ］ gas hood generator shell, ［ 6 ］ gas hood generation inner casing, ［ 7 ］ sealing gland close that device, ［ 8 ］ loam cake, ［ 9 ］ motor shroud, ［ 10 ］ sealing gland are remained silent, ［ 11 ］ air inlet, ［ 12 ］ air chamber, ［ 13 ］ gas hood mouth.
Motor ［ 1 ］ is the center that is fixed by bolts to loam cake ［ 8 ］, and loam cake ［ 8 ］ is screwed on oil smoke passage (2).Motor shroud ［ 9 ］ is leaned on the elasticity of self to be installed on and is covered motor ［ 1 ］ on the loam cake ［ 8 ］.Gas hood generator shell ［ 5 ］ is screwed below oil smoke passage ［ 2 ］, and annular air scoop ［ 11 ］ is arranged above it.Gas hood impeller ［ 4 ］ is coaxial conjuncted structure with smoke pumping impeller ［ 3 ］, be installed in jump ring and nut on the axle of motor ［ 1 ］, gas hood generator inner casing ［ 6 ］ adopts latching structure to be positioned the inner surface of gas hood generator shell ［ 5 ］, form the garden week gap that certain distance is arranged equably, this gap is gas hood mouth ［ 13 ］.It is to establish an inclined-plane to realize on the blade of gas hood impeller ［ 4 ］ that sealing gland is closed device ［ 7 ］.
During smoke exhaust ventilator work, motor ［ 1 ］ rotates, and when driving smoke pumping impeller ［ 3 ］ generation smoke pumping effect, gas hood impeller ［ 4 ］ is rotation in the air chamber ［ 12 ］ that gas hood generator shell ［ 5 ］ and gas hood generator inner casing ［ 6 ］ are constituted.Under the centrifugal action of the blade of gas hood impeller ［ 4 ］, the air in the air chamber ［ 12 ］ is discharged by gas hood mouth ［ 13 ］, be formed with the taper gas hood of certain flow rate.Gas hood impeller ［ 4 ］ is in the process of outside emptying gas hood, near the negative pressuren zone that formed of air inlet ［ 11 ］ in the air chamber ［ 12 ］, under the attraction of negative pressure, air is discharged under the blade action of centrifugal force again after air inlet ［ 11 ］ enters air chamber ［ 12 ］, and going round and beginning again so just forms airhood continuously.Gas hood impeller ［ 4 ］ rotation time, be arranged on sealing gland on the blade close device ［ 7 ］ just produce upwards have certain pressure (this pressure is greater than the interior pressure of oil smoke passage ［ 2 ］) the sealing air-flow to sealing gland remain silent ［ 10 ］ seal
