Abstract

The utility model relates to a kitchen cooker, particularly a swirling air-guiding burner, comprising a burner core 2 with an eccentric air-guiding hole 1, a burner shell with an air inlet 3 sheathed out of the burner core 2, a hollow chamber 5 penetrating the burner shell 4 and the burner core 2 and an oil pipe 7 with oil holes 6. The utility model is characterized in that the eccentric angle theta of the eccentric air-guiding hole 1 is reduced gradually from the lower end to the upper end of the burner core, and a dip angle alpha is gradually changed into an elevation angle beta via observing from the air inlet of the eccentric air-guiding hole 1; the hole diameter of the eccentric air-guiding hole 1 is regularly changed from large to small and to large; the air inlet 3 of the burner shell 4 is a tangential air inlet, or an inversed cup body 9 is suspended in the burner core 2. The swirling air-guiding burner has oil saving, energy saving and convenience for adjusting the burning degree of flame.

Description

A kind of helical wind-guiding burner

The utility model relates to a kind of kitchen kitchen range, particularly relates to a kind of helical wind-guiding burner.

At present, utilize air blast make burner that the oil plant vaporization combustion adopts mostly by the hollow stove stamen that is drilled with the eccentric air-guiding hole of 20-30 level garden week and be placed in its in addition air inlet furnace shell and run through that stove is bright to be formed with oil pipe stove stamen cornice fuel tap.The burner burning fire seedling one of this kind structure come out of the stove stamen be easy to around disperse, upwards and to around the weak effect that conducts heat few, therefore often fuel consumption is bigger for this burner; Secondly, the hole that stove stamen garden week bores is the eccentric air-guiding hole of level, and the direction that combustion air flow direction and flame combustion flow is not the same, thus can only adopt the bigger middle drum pressure blower fan of electrical power, otherwise easily produce the flourishing of incomplete combustion, environment is polluted; Moreover, this kind burner fuel-flow control narrow range, as long as the kind of burning little fire is once strengthening the oil mass over-emitting black exhaust, and the kind of burning big fire is just flame-out as long as fuel tap turns down, and is can not both burners of taking into account.

The purpose of this utility model is to provide a kind of fuel-economizing, energy-conservation helical wind-guiding burner.

Another purpose of the utility model is to provide a kind of large and small fire to regulate and changes helical wind-guiding burner easily.

The utility model is achieved in that a kind of helical wind-guiding burner, it comprises stove stamen with eccentric air-guiding hole, is placed in the outer furnace shell of bringing the air port into of stove stamen, and the oil pipe that runs through the cavity band oil flow hole of furnace shell and stove stamen formation is formed, it is characterized in that: the eccentric air-guiding hole of a. stove stamen garden on week, its eccentric angle θ reduces gradually to the upper end from stove stamen lower end, and described eccentric air-guiding hole, observes from this hole air inlet, to the upper end, become elevation angle β gradually from stove stamen lower end by angle of depression α; B. the eccentric air-guiding hole on the week of stove stamen garden, its aperture Φ be to the upper end greatly from stove stamen lower end → and little → big rule changes; C. air port that furnace shell is brought into is a tangent air inlet.

Aforementioned its eccentric angle of eccentric air-guiding hole θ: 15 ° 〉=θ 〉=0 °; Angle of depression α: 5 ° 〉=α 〉=0 ° or elevation angle β: 0 °≤β≤60 °.

Aforementioned eccentric air-guiding hole, its aperture Φ: 1mm≤Φ≤3mm.

In order to make this burner result of use better, large and small fire is easy to adjust, the back-off cup that can in the stove stamen of above-mentioned burner, suspend, and this back-off cup is supported by described oil pipe, and the top is drilled with fire jetting hole.

The burner of this structure because the particular design of eccentric air-guiding hole, when meeting fuel combustion swirl flame flow to rule, so fuel combustion is abundant, reaches the purpose of smokeless combustion, not only solves the fuel-economizing problem, has also reduced environmental pollution simultaneously; And air blast air-supply flows to and swirl flame flows to the consistent windage that has also reduced air-supply, and the also reduction greatly of requirement to the air blast of cooking stove outfit reaches energy-conservation requirement.

The back-off cup of a top band fire jetting hole of suspending in the stove stamen of above-mentioned burner forms the double combustion chamber, just can carry out large and small fire easily regulates, when the little fire burns of needs, flame only forms in the small combustion chamber in the back-off cup, form the back from the ejection of top fire jetting hole, produce the little column of flame that rotation is bright; When the big fire burns of needs, as long as suitably regulate oil inlet quantity and intake, allow the interior oil flow part of small combustion chamber arrive the cavity one large-scale combustion Indoor Combustion of stove stamen and the formation of back-off cup, the tubular rotation column of flame that the burning of large-scale combustion chamber produces and the column of flame of small combustion chamber ejection are joined and are sprayed to the bottom of heating container jointly, and this is to the purpose of quickening heat exchange.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1: the structural representation of the utility model embodiment 1.

The A-A cutaway view of Fig. 2: Fig. 1.

The B-B cutaway view of Fig. 3: Fig. 1.

Fig. 4: the structural representation of another embodiment of the utility model.

With reference to Fig. 1-3, a kind of helical wind-guiding burner, it comprises the stove stamen 2 with eccentric air-guiding hole 1, is placed in the furnace shell of bringing air port 3 into 4 outside the stove stamen 2, and oil pipe 7 compositions that run through the cavity band oil flow hole 6 of furnace shell and stove stamen formation, it is characterized in that: the eccentric air-guiding hole 1 of stove stamen 2 gardens on week, to the upper end, its eccentric angle θ reduces gradually from stove stamen lower end, and observes from this hole air inlet 8, to the upper end, it becomes elevation angle β gradually by angle of depression α from stove stamen 2 lower ends; The eccentric air-guiding hole 1 of stove stamen 2 gardens on week, its aperture Φ are to the upper end greatly from stove stamen 2 lower ends → little → big rule variation; Air port that furnace shell 4 is brought into 3 is tangent air inlet.

Above-mentioned eccentric air-guiding hole 1 its eccentric angle θ: 15 ° 〉=θ 〉=0 °; Angle of depression α: 5 ° 〉=α 〉=0 ° or elevation angle β: 0 °≤β≤60 °.

Above-mentioned eccentric air-guiding hole 1 aperture Φ: 1mm≤Φ≤3mm, total 150-200 is good.

With reference to Fig. 4, easy to adjust for large and small fire, the back-off cup 9 that can suspend in stove stamen 2 is supported by described oil pipe 7, and the top is drilled with 10 fire jetting holes 10, and its aperture is that 3～5mm is good.
