Description

Wind eddies formula suction oil gas machine

Technical field:

The present invention relates to a kind of kitchen guarding's appliance field, particularly a kind of kitchen smoke exhaust ventilator.

Background technology:

Well-known traditional smoke exhaust ventilator brand is numerous, but can be divided into two kinds of types substantially, a kind of be called European, another kind is called dark bell-type, the former is European really, and the latter only profile is different, and both internal structures are basic identical, motor places the impeller middle part mostly to be the double suction mouth, place impeller distolateral for the single suction mouth, on establish flue and discharge, divide into oil cleaner screen, auxiliary is formed an integral body, particularly: especially European its motor of all brands now, blower fan 100% all places the machine low level, approximately apart from 700 millimeters in cigarette source kitchen range top face, and most spiral case suction inlet is in static pressure set, is the operating space down, unified pattern on above-mentioned layout has come true, even general layout is constant for many years.

Tradition lampblack absorber great advantage: simple in structure, handsome in appearance.Have several families brand to make progress slightly in the recent period, but because of its basic structure still, so difficulty is seen remarkable effect, more do not reach the actual effect of being propagated in they " specification " or the advertisement certainly.

Though yet nowadays European product has almost occupied the whole markets of China, facts have proved but use for many years, perhaps it can adapt to western countries, but raising in China owing to Chinese cuisines tradition and living standards of the people, stir-fry in the culinary art, quick-fried, frying oil cigarette amount do not know to exceed west family what doubly, tradition European China can also be permanent adaptation? not! It has three big critical defects.

One, clean absorption rate is low.The lampblack absorber position is justifiable in top, cigarette source, but problem is oil smoke, here also should comprise the pernicious gas in oil gas and the combustion process, as carbon monoxide etc., they are not as desirable, leave the pot edge and head direct for suction inlet, and the part oil smoke can flow and elegant with gesture with air in personnel activity's interference and the kitchen, particularly from suction inlet flue gas far away, even you add high-powerly to this, increase suction, that also is idle work mostly, because of the major part that is siphoned away by you is nearby a room air, be not to be oil gas entirely, and the actual multiple harmful substances that contains of these elegant oil gas, as methacrylaldehyde, polycyclic aromatic hydrocarbon etc., not only pollute indoor environment, and woman's respiratory health is boiled by grievous injury family! Much boil the woman when opening the oil cauldron cooking and have what is worse, for grease proofing has channeling to parlor, bedroom, lose no time to close backstairs, would rather sacrifice health and get cleaning in return, how distressed this be one act!

Its two, noise grows louder and stronger.Because the close chip impeller of little radian is again static pressure set, the easiest grease that gathers of blade, thus progressively make impeller lose dynamic balancing, the time is grown the reduction of not only suction power slightly, and noise also grows louder and stronger, and makes you unpick and wash, and this when having unpicked and washed?

Its three, the worry of oil cleaner screen.Name say " oil cleaner screen " it how " filter " oily? to " filter " that yes that Kong Yuexiao is close more good more, but little close after, increased the suction drag of blower fan, and very fast aperture has just been blocked by greasy dirt, can that be filtered if the hole is big? moreover the non-particulate thing of oil smoke, so, is the main function of " oil cleaner screen " a draw-off tray, otherwise where past suction inlet place oil droplet down is? bring the endless worry of unpicking and washing for the user thus.

Summary of the invention:

Purpose of the present invention: be devoted to improve clean absorption rate.Be to provide a kind of and can effectively overcome above-mentioned defective, become the domestic contamination important place and be environment protection health.

Technical scheme of the present invention: realize with two kinds of methods that in order to reach the goal that is: wind eddies formula suction oil gas machine is inhaled apart from adjustable type suction oil gas machine, be called for short: adjustable type suction oil gas machine, two machine upper part power sections and electric principle are general.

Wind eddies formula suction oil gas machine: be the formation of simulating nature phenomenon cyclone under the limited conditions and characteristic Design, we are with its key factor for example now: the cyclone pressure energy of wind speed under 140 kilometers specified conditions per hour produces the suction volume power that pulls up big tree, the wind speed of its per minute is about 2335m, 2335m/60, then per second is about 39m/s, even we compare with the wind speed of conventional fan now: π x 0.25x2000=1570,1570/60 per second is about 26m/s, 0.25 is draught fan impeller diameter m in the formula, 2000r/min is the medium rotating speed of motor, but real electrical machinery also speedup wind eddies generator high negative pressure favorable factor is then not far from one another with natural spout wind speed in addition.

Wind eddies formula suction oil gas organizational security has stayed traditional European moulding and cover operating space down, with remarkable different 2 points that mainly contain of traditional machine: 1, power section be motor and blower fan by traditional machine low level dislocation in a machine high position, suction inlet is the total head direction by static pressure, blade is the rare chip of big radian, still can use reluctantly but put under condition conventional impellers in high-order total head.2, do not establish oil cleaner screen, load onto emphasis critical component of the present invention---wind eddies generator sub-assembly, establish the conveyor screw blade in this device, profile is the fluting tubulose, it has single steering characteristic, under the about 30m negative-pressure air-flow of per second high speed rotation mode, the pipe inner space is main the suction, meanwhile near the flue gas outside the body, flue gas rotates rising synchronously in will inevitably participating in managing under the negative pressure single effect, and flue gas will inevitably participate in one in the same way synchronously with above-mentioned flue gas in the core pipe this moment,---this is to pay to inhale, certainly mainly inhale outer being weaker than certainly in main the suction, thereby but their inevitable inside and outside in the same way interlocks reach the effect that pulls of similar cyclone under the subenvironment---improved clean absorption rate.In this, have partial fume and do not catch up with main flow, then can outside main suction pipe, be detained slightly for a moment in the negative pressure cabin, to enter centrifugal blower if any a little also harmless for helping suction this moment.

Flue gas rotates a few at a high speed in the body of wind eddies generator after, not only produced above-mentioned effect, more because de-oiling has been finished in the interior wall friction cooling of flue gas fluxion circle contact tube simultaneously under centrifugal action, cigarette gently rise to be discharged with gesture, and oil is heavy to be got rid of on inside pipe wall and flow into lubricating cup, thereby has replaced the repertoire that traditional what is called " filter " oil is netted in the de-oiling mode, moreover tube cavity all scribbles the polytetrafluoroethylene (PTFE) adherent layer, oil at a high speed can't glue wall, in this, realized not having oil cleaner screen exempt from unpick and wash.

This wind eddies generator profile is a tubulose, can easily operate it according to user's needs and just locate, and certainly the low more nearly suction effect in location is good more, but low excessively diminish attractive in appearance.

Be not difficult in sum to find that the wind eddies formula has following major advantage:

1. because tornado effect among a small circle, clean absorption rate is high, more environmental protection, and also structure is still simpler;

2. eliminate tradition so-called " oil cleaner screen ", adopt the de-oiling technique effect better, realized thus not having oil cleaner screen exempt from unpick and wash;

3. the not long-pending grease blade of the high set of blower fan total head moves on the motor-field with not increasing noise for a long time, and is healthy, keeps European moulding and original operating space that people like.

Adjustable type suction oil gas machine:

Adjustable type suction oil gas machine is to be lower than the European 20 ° of wall set of leaning forward, can in 70 ° of scopes, closely inhale even the lid suction regulated at will location with all suction inlets of big planar rings, make tradition be in the negative pressure circle and can't be elegant nearby away from the flue gas of suction inlet, the oil gas of going into the chamber is through rotation at a high speed, under centrifugal action, carried out de-oiling, to replace tradition " filter " oil, oil will be gone into oil groove, cigarette through on put blower fan and discharge.

Adjustable type suction oil gas machine has following major advantage in sum:

1. owing to can closely inhaling even covering suction, clean absorption rate is high, and environment protecting is good;

2. there are not the drawback of " oil cleaner screen " and the worry of frequent clean;

3. owing to there is not cover, the space occupy-place has been saved in the ring week suction inlet wall set on big plane, does not have the sorrow that former cover frame is met and discussed, and daily cleaning work is particularly convenient.
