Abstract
The invention only has three parts in the same axis: a ring conical hollow throat type cooking fume removing channel, a stove fire plate and a centrifugal fan. In order to raise efficiency of removing cooking fume, the cooking fume suction inlet and the channel is a frying pan encircling ring conical narrow gap and the gap next to the suction inlet is more narrow, so as to form a hollow throat. There is a circle of radial guide parting slips mounted in the ring conical hollow throat to make gas flow more smoothly. Because of the throat effect, the sucked cooking fume can be sucked in easily even if the suction inlet is not higher than the frying pan.
Description
Technical field
The present invention relates to a kind of gas kitchen ranges that has oil smoke suction function, particularly relate to a kind of trunnion principle of utilizing and make burning and oil suction cigarette efficient all reach the highest comprehensive kitchen range.
Background technology
The range hood of existing all styles of, its major defect be take up space, noise is big, power consumption is high, efficient is low." the forced-ventilated oil smoke kitchen range (ZL-02234971.5) that remove of deep-well side draught ", though mist extractor efficient height, noise is also little, makes cooking operation very inconvenient owing to " deeply " reaches " side ", moreover complex structure, the processing cost height.
Summary of the invention
The objective of the invention is to solve many shortcomings of existing range hood, a kind of ring conical hollow throat type oil suction cigarette gas-cooker is provided.
For achieving the above object, ring conical hollow throat type oil suction cigarette gas-cooker of the present invention is characterized in that it mainly is made up of three critical pieces on same axis, that is: ring conical hollow throat type oil suction cigarette channel, ashpan, centrifugal fan.The oil suction cigarette channel that ring wraps in the round-bottomed frying pan periphery is all narrow slots of ring, and in the slit near air inlet narrower (throat), promptly forms the trunnion shape.The inwall lower surface of ring conical hollow throat type passage is inserted the centrifugal fan suction inlet and is left annular gap with the blower fan suction inlet, lower surface and base plate are close (not influencing the blower fan rotation), and the tail end of the outer wall of ring conical hollow throat type oil suction cigarette channel closely is connected with the suction inlet of centrifugal fan.Ashpan is placed on the top of the lower surface of ring conical hollow throat type oil suction cigarette channel inwall, leave the gap that air flows on every side, leave as air chamber with a certain distance from the lower surface, air chamber communicates with atmosphere by breather pipe, and isolates with ring conical hollow throat type oil suction cigarette channel.One circle equidistant radial is housed in the whole ring conical hollow throat type oil suction cigarette channel arranges 16～32 partition, and down be in the stage casing gradually towards the bending of blower fan direction of rotation.The effect of partition, the one, work the strong effect of supporting, the 2nd, lead straight air-flow, overcome turbulent flow and reduce circulating resistance, improve flow velocity.The suction inlet plane of ring conical hollow throat type oil suction cigarette channel and the angle on round-bottomed frying pan plane are 15 °, and the outer of most significant end exceeds 15 ~ 20 millimeters on kitchen range top plane, in case the residue thing on the table top enters the oil suction cigarette channel, do not influence cooking operation simultaneously again.
After adopting technique scheme, because it is short that oil smoke sucks distance, the throat of suction inlet is near by the oil suction cigarette, (15-20 centimetre) formed vacuum in the certain altitude scope of round-bottomed frying pan top, and owing to the fluid mechanics principle of trunnion, oil smoke quickens to flow in trunnion again, the static pressure step-down, the round-bottomed frying pan top is an atmospheric pressure, forms pressure differential, and the place that pressure is big flows in the pressure circlet awl wikipedia type passage; The flame of ashpan is because of being subjected to sucking action in this process, and air inflow significantly improves, and firepower is more violent, and then has saved combustion gas and cooking time.Ring conical hollow throat type oil suction cigarette gas-cooker of the present invention has compact conformation, simple, low, the energy-conservation characteristics that do not take the operating space again of cost.Again because of blower fan below kitchen range top face, so noise is extremely low.Twin furnace dish gas-cooker is an oil suction cigarette system independently separately, but a shared blower fan.This structure is the tapering suit, and is just detachable without instrument, promptly guarantees the convenient again cleaning of sealing.

The specific embodiment
Be described further below in conjunction with accompanying drawing, conical hollow-throat typed gas burner with cooker hood of the present invention by ring conical hollow throat type oil suction cigarette channel 1, ashpan 2, air chamber 3, centrifugal fan 4, breather pipe 5, partition 6, hold lubricating cup 7 and form, 1～4 on same axis from top to bottom, the lower end of ring conical hollow throat type oil suction cigarette channel 1 is inserted the suction inlet of centrifugal fan 4 and is left annular gap with the blower fan suction inlet, lower surface and blower fan 4 bases leave gap (not influencing the blower fan rotation), and the tail end of the outer wall of ring conical hollow throat type oil suction cigarette channel 1 closely is connected with centrifugal fan 4 suction inlets.The inside and outside wall funnel of ring conical hollow throat type oil suction cigarette channel 1 because of separately tapering varies in size, forms the tapered trunnion of ring behind the suit.Ashpan 2 is placed on the top of the lower surface of ring conical hollow throat type oil suction cigarette channel 1 inwall, leave the gap that air flows on every side, leave as air chamber 3 with a certain distance from the lower surface, air chamber 3 communicates with atmosphere by breather pipe 5, and isolates with ring conical hollow throat type oil suction cigarette channel 1.Be equipped with and hold lubricating cup 7 at the place, outer, shell bottom surface of centrifugal fan.When starting centrifugal fan 4, encircling the flow velocity of the throat (the narrowest place) of tapered wikipedia type oil suction cigarette channel 1 accelerates, and it is near again from the oil smoke district, oil smoke has little time upwards to fly away and just is inhaled into 1 li of ring conical hollow throat type oil suction cigarette channel hastily, elaioleucite in the oil smoke is owing to be used to the power effect and got rid of and into hold lubricating cup 7, and all the other then are discharged from outdoor.
