Description
The present invention relates to coal gas air-cone, it is such as utilizing cook utensil to carry out boiled foods.The invention still further relates to a kind of gas range with coal gas air-cone.
Common gas burner majority in culinary art gas range has the single circle flowing out opening with coal gas, and these coal gas flows out opening and forms gas burner ring.In order to realize uniform Temperature Distribution on the bottom of a pan for king-sized pot, have developed some gas burners, it forms the flame ring arranged with one heart each other.But show, with regard to the corresponding multiple burner with multiple concentric flame circle, its efficiency is often less than single burner, namely only has the burner of a flame ring at work.The efficiency of single burner is usually between 55%-60%, and the efficiency of traditional dual flame burner only reaches 50%-52%.In order to determine the efficiency of coal gas cooking equipment, have employed standard EN 30.Inefficient reason does not obtain thoroughly understanding thoroughly, because efficiency depends on the very complicated relation of the heat trnasfer on combustion process, fluid dynamic or air force and the heating power in waste gas, pot bracing frame, pot and pot between thing.
Although efficiency is usually lower, in order to realize the temperature homogeneity of large-area improvement on the one hand, realizes the larger ratio between maximum and minimum power on the other hand, still using multiple burner.Therefore the object of the invention is to, a kind of coal gas air-cone with the improvement of multiple flame ring is provided.
Adopt a kind of coal gas air-cone with the feature of claim 1, this object can be realized.
Accordingly, be provided with a kind of coal gas air-cone, it is at least with around the inner ring of datum mark and outer shroud.The coal gas that the circumferential sectors of these rings is provided with the rate of outflow of the setting for corresponding circumferential sectors flows out opening.These circumferential sectors belong to the angular regions around datum mark at this.The rate of outflow of the adjacent circumferential section of respective rings is different.
In addition, the rate of outflow belonging to each circumferential sectors of same angular regions of these rings can be adjusted to different.
Be provided with inner ring and outer shroud thus to corresponding coal gas air-cone, its coal gas designed with the rate of outflow for setting be arranged on corresponding circumference flows out opening.Here, rate of outflow system is relative to the corresponding total coal gas discharge rate such as also flowing out opening realization by multiple coal gas in circumferential sectors.
The coal gas rate of outflow records according to the volume flow in the unit interval, such as, rise number to record by coal gas per hour.So the rate of outflow is directly corresponding to the combustion power particularly depending on coal gas used.Such as, the natural gas of 100 liters per hour is roughly equivalent to the combustion power of 1050 watts.
Usually, with regard to traditional multiple air-cone, the coal gas of inner ring or internal flame circle flows out opening through suitably design, high as far as possible under making the intended size situation of the combustion power in interior zone in combustion physics, such as with regard to the burner of 6kW, in interior zone, preferably have 1kW, such as, only have 500W.But the research of applicant shows, in any case advantageously, the combustion power in interior zone keeps below degree possible in combustion physics, that is such as preferably 500W in the above-mentioned case, instead of 1000W.
According to the research and analysis of applicant, the waste gas of the combustion process in internal flame ring can disturb the flame of external flame ring.Can think, the waste gas of internal flame ring forms separation layer between cook utensil and external flame circle, and this finally causes efficiency lower.In addition, the waste gas streams of internal combustion process also can disturb external flame.
In proposed coal gas air-cone, by flowing out the design of opening to coal gas, produce larger flame and less flame, or generation have the combustion power higher relative to corresponding circumferential sectors and each circumferential sectors of lower combustion power, thus produces different waste gas streams.
On the one hand, circumference along inner ring and outer shroud produces the different rates of outflow, and then produce the flame of different size, on the other hand, such as outwards produce flame section from internal reference point, these flame sections are observed less than external flame from inside, thus have lower power, realize thus improving the heat trnasfer from waste gas to cook utensil on the whole, and improve the burning of coal gas.Especially, by the different rates of outflow, and then by different flame size, achieve the interference reduced outside flame rings.In addition, the waste gas improving internal flame ring flows out, and then the isolation between reducing bottom external flame and corresponding cook utensil.
Coal gas flows out opening such as can suitably be arranged, makes on corresponding circumference, have the circumferential sectors with the high rate of outflow and the low rate of outflow alternately.So the circumference along such as inner ring and outer shroud produces large flame section and flammule section.
In addition, coal gas flows out opening can be arranged or design through suitable, making with regard to the circumferential sectors with regard to belonging to same angular regions, alternately having the high rate of outflow and the low rate of outflow in each circumferential sectors adjacent diametrically.Thus can consider, no matter on tangential along corresponding flame ring, still diametrically, light from the such as concentric benchmark of inside, all produce putting in order of large flame and flammule all the time.
According to a kind of Variant Design of coal gas air-cone, each coal gas flows out opening and only points to same direction from datum mark diametrically.So flame all only outwards burns along radius.So the flame of inside sensing is not arranged.
In a kind of embodiment of coal gas air-cone, be equipped with disk as interior, and outer shroud and this disk are arranged with one heart.But also can consider other geometry, such as oval or polygon ground arranges that each ring and/or coal gas flow out opening.Here may relate separately to the requirement of such as cook utensil, or relate to the mounting condition of coal gas air-cone.
Booster flame (Halteflamme) can be equipped with to flow out opening for coal gas air-cone or flame for subsequent use (St ü tzflamme) flows out opening.Even if in order to still obtain stable flame in the king-sized situation of gas flow flowing through outflow opening, can flow out between opening at two coal gas and some less booster flame opening or flame openings for subsequent use are set.Further improve the combustion characteristics of coal gas thus.
In order to regulate the corresponding rate of outflow, can arrange to have such as to flow out opening for the coal gas of the first cross section of large flame or the high rate of outflow and have and such as flowing out opening for the coal gas of second (less) cross section of flammule or the low rate of outflow.
According to another Variant Design of coal gas air-cone, flow to the Gas Flow flowing out opening to regulate through suitable, the rate of outflow making each circumferential sectors of inner ring circumferentially line alternately corresponding to the first combustion power and the second combustion power, and the rate of outflow of each circumferential sectors of outer shroud circumferentially line alternately corresponding to another first combustion power and another second combustion power.With regard to inner ring, such as alternately had the circumferential sectors of high (first) and low (second) combustion power, wherein high combustion power and low combustion power are for inner ring toward each other.Similarly, the circumference along outer shroud is provided with the circumferential sectors alternately with high (first) and low (second) combustion power.At this it is possible that the circumferential sectors compared to the adjacent circumferential section of outer shroud with low combustion power of outer shroud, compared to the circumferential sectors belonging to same angular regions of inner ring, there is higher combustion power.Equally, the adjacent circumferential section of the adjacent angular regions in inner ring has lower combustion power.Relevant explanation is such as high or low for these rings.
So according to another Variant Design, also the combustion power of each circumferential sectors belonging to same angular regions is suitably designed, make first (high) combustion power of corresponding internal circumference section adjacent with the exterior periphery section with another second (low) combustion power respectively diametrically.So the adjacent circumferential sectors of inner ring has second (high) combustion power, the exterior periphery section all belonging to same angular regions has another first (high) combustion power.High or low combustion power is also the circumferential sectors for respective rings.
According to a kind of decision design of coal gas air-cone, each angular regions at least sandwiches 30 °.According to a kind of alternative design, these angular regions all formed objects.The angle intervals that two coal gas of preferred circumference flow out between opening is at least adjusted to 6 °.In order to regulate the corresponding rate of outflow of each circumferential sectors on same circumference, the coal gas that the adjacent circumferential section on same circumference can have varying number flows out opening.
One according to coal gas air-cone is improved, and is provided with other outer shroud of at least one band circumferential sectors and coal gas outflow opening.Thus this outer shroud such as also can be made up of three or four flame rings, to heat king-sized pot face.
Adjusting device can also be provided with by coal supply gas air-cone, this adjusting device suitably control flow check flows out the Gas Flow of opening to coal gas, make the combustion power of the adjacent circumferential section of respective rings different, and the combustion power belonging to each circumferential sectors of same angular regions of these rings is different.
According to the particularly preferred design of the one of coal gas air-cone, be only provided with two concentric flame rings or circle, the coal gas that they have outwardly flows out opening, and has the section with the different rate of outflow alternately as described.Especially, two different rate of outflow levels are only provided with for each circumferential sectors and ring.In a word, total combustion power can be changed according to the duty of burner, and then change the Gas Flow flowing to coal gas air-cone.Previously about the explanation of the different rate of outflow, be in the given combustion power situation of total gas burner for the rate of outflow of each circumferential sectors toward each other.
Other possible embodiment of the present invention also comprises before this or below with regard to the not specifically mentioned combination of the feature described in embodiment, method step or aspect.Here, those skilled in the art also can add some independent aspects as improvement or supplementary for corresponding citation form of the present invention.The present invention particularly comprises the gas range or gas range that are equipped with coal gas air-cone as above.

9=30 °.By these angular regions, the outward flange of inner disc 2 and the outward flange of outer shroud 3 set circumferential sectors, put on Reference numeral 7,8,9 wherein to respectively three inner periphery sections, and put on Reference numeral 4,5,6 to three excircle sections.The circumferential sectors 7,8,9 of inner ring and rounded face 2 and the circumferential sectors not putting on Reference numeral define the circumference of circumference L1 or inner ring 2.Similarly, circumferential sectors 4,5,6 and other circumferential sectors not putting on Reference numeral define the circumference L2 of outer shroud 3.
Be provided with some coal gas along inner circle contour L1 and cylindrical contour L2 now and flow out opening 10,11, flow out opening when gas burner 1 works from these coal gas and jet out flames 110,111.In addition for convenience of explanation, angle section α will be investigated
7, α
8, α
9.Obtain circumferential sectors 7,8,9 at inner circle contour L1 thus, and circumference L2 obtains circumferential sectors 6,4 and 5 outside.For convenience of explanation, suppose that coal gas is flowed out opening 11 to be arranged for large flame 111 below, and coal gas outflow opening 10 is arranged for less flame 110.The combustion power of the corresponding rate of outflow and then determined flame size and local such as can by respective streams export 10,11 size or cross section regulate.Also can consider to control and regulate the actual Gas Flow flowing out opening for each coal gas outflow opening 10,11 or each group coal gas, as described below.
At angular regions α
7in, the coal gas that inner periphery section 7 has for flammule 110 flows out opening.At same angular regions α
7in, the coal gas that circumferential sectors 6 has for large flame 111 flows out opening 11.At adjacent angular regions α
8in, coal gas inner periphery section 8 is provided with for large flame 111 flows out opening.At same angular regions α
8in, the coal gas that circumferential sectors 4 is provided with for flammule 110 outside flows out opening 10.At the angular regions α for inner periphery section 9 and excircle section 5
9in, be also provided with for the outward opening of large flame 111 and the inner opening for flammule 110.Thus these circumferential sectors alternately arrange along corresponding circumference L1, L2, and the coal gas for large flame flows out opening 11 and thus has the high rate of outflow, and thus has the low rate of outflow for the coal gas outflow opening 10 of flammule 110.Thus adjacent circumferential sectors has the different coal gas rates of outflow all the time.The high rate of outflow and the low rate of outflow that opening makes the adjacent circumferential section belonging to same angular regions have respectively to replace equally can also be flowed out by arranging different coal gas.Such as at angular regions α
8in, the large flame 111 sprayed from inner periphery section 8 is surrounded by the flammule 110 of excircle section 4.By the circumferential sectors 6 and 5 that two angles are adjacent, each group flammule 110 is surrounded by large flame 111.Radially alternately arrange large flame and flammule from inside to outside by this circumferentially line L1, L2, obtain particularly advantageous combustion characteristics.
Therefore create the inner periphery section 8 with large-scale combustion power, they are surrounded by the inner periphery section 7,9 with little combustion power.Correspondingly there is the excircle section 5,6 with large-scale combustion power, they adjoin with the adjacent excircle section 4 with little combustion power respectively.Little combustion power or large-scale combustion power be with reference to ring circumferential sectors comparatively speaking.
Such as, the combustion power in full of outer shroud 3 is 5kW, is distributed in 48 coal gas altogether and flows out opening 10,11.By the size of opening 10,11, the difference of the combustion power of outer shroud 3 circumferentially section 4,5,6 flows out VELOCITY DISTRIBUTION.Meanwhile, when inner ring is fully burnt, the combustion power of 700W can be had to be distributed in 18 coal gas and to flow out opening 10,11.When turning i.e. flame down and being minimum, the proportionate relationship of whole combustion power and outer combustion power can be such as the combustion power of outer combustion power to 300W of 1300W.Usually, coal gas flows out the rate of outflow of opening 10,11 or combustion power can regulate between the minimum of a value of 1:4-1:5 and maximum.
Fig. 2 is the schematic stereogram of coal gas air-cone 1.There is illustrated inner ring 2 and outer shroud 3.Coal gas flows out opening and is made up of the otch on inner ring 12 and outer ring 13, and inner ring or outer shroud 2,3 rest on described inner ring and outer ring.As seen from Figure 2, coal gas air-cone constructs symmetrically about central axial line A.As shown in top view 1, inner ring has the circumferential sectors that band first coal gas flows out opening 11, and the coal gas that their rate of outflow is greater than in therebetween circumferential sectors flows out opening 10.Correspondingly, outer ring 13 is also provided with some flow out opening 11 and little coal gas outflow opening 10 circumferential sectors with large coal gas.Air-cone 1 or enclose 12,13 accordingly and can be enclosed within sleeve pipe 14, coal gas to be combusted arrives coal gas via this sleeve pipe and flows out opening 10,11.Visible, the corresponding large rate of outflow or the little rate of outflow can be realized by the cross-sectional area in corresponding coal gas outflow opening or hole 10,11.
It is the schematic sectional elevation of coal gas air-cone 1 shown in Fig. 3.As seen from Figure 3, the inner ring 2 and the outer shroud 3 that originate in the axis of symmetry or medial axis A such as can be formed by about the rotational symmetric profile of axis A.Inner ring 12 and outer ring 13 are all positioned on sleeve pipe 14.According to orientation shown in Fig. 3, coal gas G to be combusted from left to right top flow to opening 10,11.Coal gas flows out opening 10,11 through suitably design in sectional elevation 3, and make in investigated circumferential sectors, internal flame 110 is less than external flame 111.The waste gas E1 produced by combustion process from internal flame ring 110, along the bottom surface of cook utensil 15 such as pot radially to outflow.At pot edge or outside outside flame ring 111, combustion product is mixed in waste gas E2.
Make internal flame 110 have less combustion power, will only have a small amount of waste gas E1 from inside to outside to flow, and seldom participate in the combustion process of outside large flame 111.In addition, the less burnt gas E1 of share is less than common many flame burner for the degree of isolation of cook utensil 15, and common many flame burner often make internal flame circle with higher, circumferentially equally distributed power work.With regard to the in figure 3 unshowned circumferential sectors adjacent with Fig. 3, corresponding internal flame is greater than external flame.That is, outside flammule is less by the degree of combustion product interference, thus can heat be delivered on cook utensil with improving.Alternation ground or alternately setting have the section of large flame and flammule or have the section of the high rate of outflow and the low rate of outflow, this provide and reliably and efficiently spray combustion design.
It is the schematic detail drawing of the coal gas outflow opening such as on combustion ring or outer fire ring shown in Fig. 4.Use booster flame can improve burning in the extra high situation of the rate of outflow.For this reason as shown in Figure 4, be provided with conventional coal gas and flow out opening 11, and be provided with the coal gas for the formation of booster flame or flame for subsequent use little especially between which and flow out opening 16.Flame for subsequent use prevents flame from peeling off from coal gas opening and preventing flameout.
