Describe with regard to embodiments of the invention with reference to the accompanying drawings.
(the 1st embodiment)
As shown in Fig. 1 (a) and (b), burner body 1 is by internal perisporium 3 and periphery wall 4 mixing chamber 2 of looping integrally, at the central portion substantially of this burner body 1, forms auxiliary air with peristome 5 in the part of being surrounded by internal perisporium 3.
Flame hole formed body 6, the sheet metal material with austenitic stainless steel such as SUS304, SUS316, SUS321 or hear resistances such as ferritic stainless steel such as SUS430, SUS436, excellent corrosion resistance is configured as truncated cone shape substantially.
6 mounting or dismounting of this flame hole formed body are matched with burner body 1 freely, in the center upper portion of flame hole formed body 6 upper opening portion 7 are set, and constitute the big down inclined plane 8 that tilts of to the bottom from the top of flame hole formed body 6 littlely.On inclined plane 8, along above-below direction radially decentralized configuration pass a plurality of narrow slits 9 on inclined plane 8 and constitute flame mouth part 10, constitute the combustion front that makes from the pre-mixed gas burning of burner body 1.Moreover combustion front is provided with obliquely to the auxiliary air of the soup juice shutter body of hereinafter addressing 12 foreign side with passage portion 11.In addition, flame mouth part 10 is not limited to narrow slit 9, also can be the aggregate of a plurality of flammule mouths.
Soup juice shutter body 12 usefulness brass etc. forge the factorial lumber material and form, be to prevent that soup juice from dropping to the flame mouth part 10 of flame hole formed body 6, constitute the auxiliary air passage portion 11 that is connected with peristome 5 with the auxiliary air of burner body 1 on central tubular ground, be placed to the top of the flame mouth part 10 that is positioned at flame hole formed body 6 at least, and then, the external diameter of the peripheral part of soup juice shutter body 12 is equated with the external diameter of the bottom of the flame mouth part 10 of flame hole formed body 6 or strengthen about 1～2mm, when seeing from above, become the formation that comprises flame mouth part 10, side is provided with groove 16 as the mechanism of dripping below peripheral part.Moreover, though soup juice shutter body 12 forges the factorial lumber material with brass etc., also can be same with flame hole formed body 6, except the material of hear resistance, excellent corrosion resistance, use ceramic formation body, aluminium etc.
Here, flame hole formed body 6 and soup juice shutter body 12, by means of be located on the soup juice shutter body 12 kick 13 and therewith a kick 13 be located at mating holes 14 on the flame hole formed body 6 accordingly and determine both cooperation positions, finally the upper opening portion 7 of flame hole formed body 6 is cooperated with passage portion 11 with auxiliary air, the top of flame hole formed body 6 is closely contacted with soup juice shutter body 12 via retainer ring 15.The flame hole formed body 6 of this moment and the mated condition of soup juice shutter body 12 become loose state.
At this moment, burner body 1 concerns with the position of soup juice shutter body 12, auxiliary air internal perisporium 3 air-tight fit of passage portion 11 and burner body 1 that become the tubular of soup juice shutter body 12, on the other hand, the bottom of flame hole formed body 6 is via periphery wall 4 air-tight fit of soup juice guide 17 with burner body 1.As previously mentioned, because the mated condition of flame hole formed body 6 and soup juice shutter body 12 is loose, thus the resistance of both air-tight fit when the burner body 1 reduced, because can successfully cooperate, so can prevent the leakage of fuel gas.
Moreover, integrated though flame hole formed body 6 and soup juice guide 17 are crimped cooperation, also can make both mounting or dismounting freely.And then the outer peripheral face 20 of soup juice guide 17 is made the size of the whole mixing chamber 2 that covers burner body 1, and being tilted to down slowly, and peripheral end spreads all over and is bent downwardly allly entirely.In addition, between the outer peripheral face 20 of burner body 1 and soup juice guide 17, form the space, limit space with the outer peripheral face 20 of soup juice guide 17 by means of the jut 21 of burner body 1.
And then, as shown in Fig. 1 (b), flame mouth part 10 is made, on the inclined plane 8 of flame hole formed body 6, along the above-below direction narrow slit of the two or more length of decentralized configuration radially, constitute a short narrow slit 23 and shorter narrow slit 24 and be configured between the adjacent long narrow slit group 22, short narrow slit 23 and shorter narrow slit 24 are located at the top of flame mouth part 10.In addition, the shape of the upper and lower side of each narrow slit is made semicircle.
In the above-described configuration, as shown in Fig. 1 (a), pre-mixed gas spreads equably in mixing chamber 2 and from flame mouth part 10 ejections, forms flame 25 by means of certain ignition mechanism.At this moment, though the flame 25 that forms in flame mouth part 10 places produces along the tapering on inclined plane 8 with being tilted to, at this moment, the 1st secondary air streams 26 is diffused into the flame 25 from the peripheral part of flame hole formed body 6.On the other hand, the 2nd secondary air streams 27 is via being diffused in the flame 25 with the upper surface of passage portion 11 along soup juice shutter body 15 with the auxiliary air that peristome 5 is connected with the auxiliary air of burner body 1.Thereby flame 25 becomes by the 1st secondary air streams 26 and the 2nd secondary air streams 27 and clips, and is promoted burning and becomes thermal-flame near flame mouth part 10, can realize low CO burning and short flameization.
And then, angle of inclination by means of inclined plane 8, the ejection angle of flame 25 is changed, because can take into account the homogeneity that adds heat distribution in the culinary art, with prevent that soup juice is to the intrusion in the flame mouth part 10, so in the present invention, though the scope (preferably 18 °～20 °) of the angle initialization that makes progress on inclined plane 8 at 15 °～30 °, as extreme occasion also can consider flame mouth part 10 on the general planar to directly over the formation of opening.
In addition, not only because soup juice shutter body 12 sees it is the formation that comprises flame mouth part 10 from above, directly drop to flame mouth part 10 so can prevent soup juice etc., and because between the bottom and flame hole formed body 6 upper ends of soup juice shutter body 12, flame 25 is easy to generate stagnation facing to the bottom of soup juice shutter body 12, the fuel gas that blows away easily can obtain the flame retentivity, so even also can form stable flame.
And then, because side is provided with groove 16 as the mechanism of dripping below the peripheral part of soup juice shutter body 12, thus flow to the soup juice of the peripheral part of soup juice shutter body 12 be prevented from groove 16 places near flame mouth part 10 around going into.The effect of this water is even replace groove 16 also can obtain same effect with the bar shaped projection.
In addition, the sheet metal material of austenitic stainless steels such as flame hole formed body 6 usefulness SUS304, SUS316, SUS321 or hear resistances such as ferritic stainless steel such as SUS430, SUS436, excellent corrosion resistance constitutes, the minimum widith pressure processing of narrow slit 9 can be become 0.8～1.2 times scope of thickness of slab whereby, the shape of narrow slit 9 not only in addition can also the enlarged rounded hole, the selection free degree of flame hole shape such as dihedral hole.For example, in the present embodiment, the thickness of slab of flame hole formed body 6 is 0.6mm, and the minimum widith of narrow slit 9 is taken as the scope of 0.59～0.65mm.Thereby, in the occasion of the fast fuel of burning velocity as hydrogen and AIR MIXTURES, though the thickness of slab of attenuate flame hole formed body 6, also can be the minimum widith optimization that prevents the narrow slit 9 that back-fire is used.
And then, even low quantity combusted also because constitute flame hole formed body 6 with corrosion resistant plate, so the commitment after igniting just can make the temperature rising of flame mouth part 10, so that flame stable lighted is also very fast, can prevent the phenomenon of stopping working.Thereby, because in wide region, flame is concentrated obliquely upward, can prevent thermal transpiration whereby from the large-scale combustion amount to low quantity combusted, transmit burner with very wide firepower variable range so can realize having high efficiency heat.
In addition, because flame mouth part 10 is made along the above-below direction decentralized configuration formation of passing a plurality of narrow slits 9 on inclined plane 8 radially, so the flame in each narrow slit 9 places ejection becomes the film shape, and then because of lower side at flame mouth part 10, widen with the interval of adjacent narrow slit 9, so further promote of bottom the diffusion to flame 25 of the 1st secondary air streams 26, can realize low CO burning and short flameization from flame mouth part 10.
In addition, even propagate just in case soup juice is invaded in the flame mouth part 10 and along the inner face of flame mouth part 10, reach near the auxiliary section of burner body 1 and flame hole formed body 6, also propagate and positively flow in the burner body 1 along downward inclination 18 as interior week of the nappe 19 of soup juice guide 17, because can stop of the intrusion of soup juice to the auxiliary section, so burner body 1 and flame hole formed body 6 are not fixed together by soup juice, do not have obstacle in both mounting or dismounting.
And then, as shown in Fig. 1 (b), flame mouth part 10 is made along the inclined plane narrow slit of the two or more length that 8 above-below direction is provided with radially, the short narrow slit 23 of configuration, shorter narrow slit 24 between adjacent long narrow slit group 22, constitute whereby, when the large-scale combustion amount, short narrow slit 23, shorter narrow slit 24 are suppressed at the flame interference each other that long narrow slit group 22 places form, can realize short flameization to 25 whole the cutting apart of flame that form in flame mouth part 10 places, even and then under low quantity combusted, also can easily carry out the whole fire of leaping up of flame mouth part 10.At this moment, as long as short narrow slit 23, shorter narrow slit 24 are located between each long narrow slit group 22, where be located at can, particularly, by being arranged on the upper side of flame mouth part 10, the fire of leaping up can carry out more reliably.
In addition, make semicircle by upper and lower side shape, because can when the fuel pre-mixed gas passes each flame mouth part 10, prevent the turbulization in the both ends each narrow slit 9, so not only can suppress raising of flame, and can when processing flame mouth part 10, prolong the life-span of metal pattern.
As above explanation, by above-mentioned formation, can provide the direction that can make flame 25 promote upwards, simultaneously from around auxiliary air diffusion and improve combustion rate, guarantee the very wide strong and weak amplitude of accommodation, shorten the length of flame, can also suppress the burner that the cooking pot of accumulating of soup juice is used.

In addition, because the flame hole formed body constitutes with the metallic plate that stainless steel etc. has hear resistance, corrosion resistance, so, if form flame at the flame mouth part place then the temperature of flame mouth part is risen rapidly, so fixedly lighting of flame also can prevent to stop working rapidly phenomenon.And then constituting flame mouth part by pressure processing becomes possibility, and the range of choice of thickness of slab also enlarges, and compares with the forging processing or the casting processing of prior art, and the selection free degree that the shape of flame hole, size, flame hole are arranged also can enlarge.Particularly, two bodies can be divided into the metal pattern that constitutes flame mouth part,, the multi-sizeization of the flame hole of flame mouth part can be made again so can make the formation on inclined plane identical because constitute the metal pattern on the inclined plane of flame hole formed body.
In addition, because soup juice shutter body uses the material different with the flame hole formed body to constitute, so can for example wait and constitute the flame hole formed body with stainless steel, on the other hand soup juice shutter body is made hear resistance or the corrosion resistance material (for example brass etc.) lower than flame hole formed body, perhaps aluminum that Lian Jia corrosion resistance is high etc., various material of soup juice shutter body, flame hole formed body be combined into possibility.
In addition because soup juice shutter body is provided with the mechanisms of dripping such as groove, bar shaped projection below peripheral part, so can by means of the mechanism of dripping stop effectively soup juice below soup juice shutter body around going into.
In addition, because soup juice shutter body with the flame hole formed body between form the auxiliary auxiliary air path that is connected with passage portion with auxiliary air, so, as the 2nd secondary air streams in the ascending air inflow auxiliary air usefulness passage portion, flow into effectively near the flame mouth part via auxiliary auxiliary air path, so the diffusion of combustion air in flame becomes well, can promote burning and lack flameization.
In addition, because soup juice shutter body sealing auxiliary air is used the upper end of passage portion, so flow into auxiliary air with the 2nd secondary air streams in the passage portion as ascending air, all supply near the flame mouth part via auxiliary auxiliary air path, can further promote to burn and lack flameization.
In addition, because soup juice guide is constituted and is arranged on the interior week of the bottom of flame hole formed body by Zhou Duan nappe down in making, the forward nappe of stating covers auxiliary section between burner body and the flame hole formed body, so, even propagate just in case soup juice is invaded the interior inner face along flame mouth part of flame mouth part, reach near the auxiliary section of burner body and flame hole formed body, also can be along downward interior week the holding propagation and positively flow in the burner body of nappe, stop of the intrusion of soup juice to the auxiliary section, so burner body and flame hole formed body are not fixed together by soup juice, do not have obstacle in the mounting or dismounting of burner body and flame hole formed body.
In addition; because the flame maintaining body constitutes on the peripheral part of soup juice shutter body dip portion is set; cover near the top of flame mouth part; so can constitute one to flame maintaining body and soup juice shutter body; because can make the part of flame collides mutually with dip portion reliably; guarantee the flame retentivity so blowing away of flame can be suppressed; even when hanging down quantity combusted, also can prevent to stop working; simultaneously can guarantee the fire of leaping up rapidly, the result can realize the smooth combustion in the very wide quantity combusted variable range.
In addition, adopt cooking pot of the present invention, then because have: the kitchen range face that has the cooking pot peristome, what have the burner peristome and be arranged on aforementioned cooking pot peristome connects the soup ware, be arranged on aforementioned range that connects the top of soup ware, and be arranged on the burner described in the claim 7 or 8 of previous combustion device peristome; With the corresponding position of short narrow slit of previous combustion device on the corpus unguis of aforementioned range of configuration, so the short flameization by flame can make pot wait the distance of heating object and burner approaching, simultaneously because the corpus unguis of range be positioned at short narrow slit just above, so corpus unguis is not toasted by flame consumingly, can not only guarantee the high thermal efficiency but also guarantee that the cooking temp of homogeneous distributes.
As above explanation, adopt burner of the present invention, since be provided with on the flame hole formed body make combustion front towards above the flame mouth part of opening, in order to prevent soup juice from dropping to the flame mouth part of this flame hole formed body soup juice shutter body is set, so the ejection angle of flame becomes upwards, can suppress peripherad diffusion and realize concentrating of heat, simultaneously because catch the soup juice that flows down by soup juice shutter body, can prevent soup juice to the intrusion in the flame mouth part, pretend to cooking pot and can guarantee the high thermal efficiency with burner.
In addition, adopt cooking pot of the present invention, owing to connect the soup ware what the cooking pot peristome of kitchen range face was provided with the burner peristome, with the corresponding position, top of the short narrow slit of the burner that is located at the burner peristome on, configuration is located at the corpus unguis of range of the top that connects the soup ware, so the short flameization by flame can make pot wait the distance of heating object and burner approaching, simultaneously because the corpus unguis of range be positioned at short narrow slit just above, so corpus unguis is not toasted by flame consumingly, can not only guarantee the high thermal efficiency but also guarantee that the cooking temp of homogeneous distributes.
