Abstract
Disclosed is an air-flow air-cushion type oil fume exhausting fan, pertaining to the class of the oil fume exhausting machine, which is composed of a machine body, a motor, blades and a back cover board; wherein, the motor and the blades inside the machine body are reversely installed, i.e., the motor is arranged in the front of the blades; an inner-expansion air exhausting passage which is combined by an air exhausting passage ring, a honeycomb-shaped air-cushion ring and a panel, an axial airflow air-cushion sleeve composed by a ring-shaped gap between the air exhausting passage ring and the honeycomb-shaped air-cushion ring, and a vertical airflow air-cushion sleeve composed by the honeycomb-shaped air-cushion ring are arranged inside the machine body. When the utility model is used, the airflow brought in by the rotation of the blades is attracted by negative pressure to flow stably and orderly, and then is exhausted compulsively by the blades. The turbulent airflow is quickly exhausted out inside the enclosure of the axial airflow air-cushion sleeve and the vertical airflow air-cushion sleeve. The oil fume will not contact with the inner wall of the air exhausting passage in the course of exhausting, so the problem that the oil fouling is easily accumulated in the oil fume exhausting fan is solved at root.
Description
Technical field
The utility model relates to the kitchen vapo(u)r exhaust fan, especially relates to a kind of air flow and air cushion type vapo(u)r exhaust fan with air-flow air cushion dynamic structural system.
Background technology
Modal in the market vapo(u)r exhaust fan has venetian blind type, axle movable blade type, blade turnable, and air exhaust passage has cylinder barrel shaped, 90 ° of bendings of rectangle.The patent No. is 99235464.1 ventilating fans of announcing, on commercially available ventilating fan basis, some improvement have been done, be about to back cover by the square circle that changes into, lobe numbers changes 3 or 4 into by 6, with shutter by the front that alters course, back, but it does not still tackle the problem at its root, and takes a broad view of commercially available ventilating fan, has some total problems in various degree.One, in anti-mosquitos and flies, mouse inlet chamber, and wind blows into indoor, door closure is placed in panel before, diminish the attractive in appearance of kitchen space, and out of control easily; Its two, be the arrival end that fan blade generally is placed in air exhaust passage, the oil smoke mist of blade forced discharge is in turbulent condition, the long air exhaust passage wall of strong collision contact causes the accumulation of greasy dirt grease repeatedly; Its three, be that the bracing frame of fixing motor is thick, increased resistance, aggravation turbulent flow; Its four, be that blade is when high speed rotating, because of the friction with the oil smoke mist adheres to greasy dirt, under action of centrifugal force, get rid of to the air exhaust passage wall, cause the overlapping accumulation of greasy dirt grease, above-mentioned reason is exactly that existing vapo(u)r exhaust fan produces the very crux of building up the greasy dirt grease.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of generation that can limit the greasy dirt grease from the source, avoid the pollution of vapo(u)r exhaust fan, improves the air flow and air cushion type vapo(u)r exhaust fan of kitchen environment.
The implementation of the utility model purpose is that the air flow and air cushion type vapo(u)r exhaust fan includes body 19, motor 10, blade 9, back shroud 6.Motor, blade are inverted, and the motor that is positioned at air exhaust passage circle 2 air flow inlet ends is fixed on the thin slice shape bracing frame 11, are positioned on the rear end that blade on the motor drive shaft is in the air exhaust passage circle.Be provided with the internal expanding air exhaust passage 12 that is combined into by air exhaust passage circle 2, honeycomb cushion circle 3 and panel 1 in the body; The axial flow air cushion that is made of the annular gap 13 between air exhaust passage circle 2 and the honeycomb cushion circle overlaps 16; And the longitudinal air flow air cushion 18 that constitutes by the honeycomb hole 17 of honeycomb cushion circle.Back shroud 6 is by last connecting rod 5, and band groove connecting rod 4, angle of oscillation enlarge mechanism 8 and be connected with body 19, and angle of oscillation enlarges the mechanism termination and connects control stick 7.
The utility model is inverted blade 9, motor 10 in body 19, and be provided with internal expanding air exhaust passage 12, vertically, 16,18 3 devices of axial flow air cushion cover, they have constituted air-flow air cushion dynamic structural system, the gas that can strict restriction be discharged is by the intention operation of the utility model design.
Before blade, air-flow is subjected to the attraction of negative pressure, with steady orderly Laminar Flow, since be subjected to again terminal shaft to the restriction of longitudinal air flow air cushion covering device 18,16, produce an entad lift angle between laminar air flow and the air exhaust passage wall, add internal expanding air exhaust passage structure, be discharged contacting of flow shedding and air exhaust passage wall, eliminate the root that produces the greasy dirt grease thereby make.
After blade: inverted blade 9 is positioned at the rear end of air exhaust passage; Thin slice shape bracing frame 11 resistances of fixing motor 10 are very little, are placed in before the blade, and the turbulent airflow of blade forced discharge does not run into any resistance, but overlapped 18,16 encirclement and hightail fan by axial and longitudinal air flow air cushion; Therefore the utility model has fundamentally been eliminated existing vapo(u)r exhaust fan and has been produced the root of building up the greasy dirt grease.The utility model and existing vapo(u)r exhaust fan are just got rid of accumulation greasy dirt grease and are compared, and significantly effectively, have reached the purpose in environmental protection kitchen.
Back shroud is by last connecting rod 5, and band groove connecting rod 4, angle of oscillation enlarge mechanism 8 and be connected with body, and angle of oscillation enlarges the mechanism termination and connects control stick 7.Pull down control stick 7, angle of oscillation enlarges mechanism and drives band groove connecting rod 4, goes up connecting rod 5, and back shroud 6 is opened; Otherwise, on push away control stick, the back shroud closure.The angle of oscillation that band groove connecting rod 4, angle of oscillation enlarge mechanism 8 is respectively 107 °, 58 °.Angle of oscillation enlarges the flexible stroke that control stick 7 can shorten in mechanism, makes rapid operation, durable, does not also take kitchen space.
Motor places the arrival end of air exhaust passage circle.Motor is fixed on the thin slice shape bracing frame 11, and thin slice shape bracing frame is fixed on the boss 14 of air exhaust passage circle 2 with screw 15.Thin slice shape bracing frame 11 thick 0.8-1.2mm, wide 10-20mm.Blade places the rear end of air exhaust passage circle, and the floor projection 1/3-1/4 of blade 9 is positioned at the rear end of air exhaust passage circle 2, and 2/3-3/4 drops in the honeycomb cushion circle 3.
Air-flow air cushion dynamic structural system ruuning situation of the present utility model is seen Fig. 5, and A is the air-flow that is discharged among the figure.B is axial and longitudinal air flow air cushion covering device dynamic structure.C is the centripetal force that produces when being subjected to the steady orderly laminar gas flow of vacuum suction.
