形成於較其他子火嘴焰孔84a較低處。 如此’由於將子火嘴焰孔84a設置於第2母火嘴焰孔83c 下方之較低位置，因此，即使是像中式菜鍋底面朝下方凸 出之曲面形狀之調理容器P時，子火嘴焰孔84a與調理容器p 之底面之間的距離也不會太短。因此，在子火嘴火焰Fc朝 上方升起且窄到某種程度之狀態下，會到達調理容器P之底 面中央部’且調理容器P之底面中央部由子火嘴火焰Fc加 200923276 熱。又，可抑制往子火嘴火焰以外方擴展，同時第2母火嘴 焰孔83c存在於比子火嘴焰孔84a高之位置，因此第2母火嘴 火焰Fb會因為子火嘴火焰Fc而不會由上方被壓到而可升 起，亚且調理容器P之底面之徑方向中間部由第2母火嘴火 feFb加熱。進而，藉第丨母火嘴火焰以加熱調理容器p之底 面外周部。藉此，調理容器P之熱分布可及時提升。 又’第2母火嘴火焰被子火嘴火焰由上方下壓時，第2 母火嘴火焰會沿著母火嘴頭部83之上面而成為壓散之火焰 形狀，母火嘴頭部83因第2母火嘴火焰而變成炙熱的高溫， 耐久性惡化。另一方面，本實施形態中，第2母火嘴火焰Fb 不會如上述被子火嘴火焰Fc由上方下壓而可升起，因此， 可抑制第2母火嘴火焰孙造成母火嘴頭部83之過熱，防止耐 久性的惡化。 另，也考慮將基底部81形成中空圓盤狀，並且將子火 嘴頭部84—體形成於其上面中央部。可是，在這當中，二 -欠空氣由子火嘴焰孔84a噴出之混合氣之燃燒部份的供給 會各易不足，又’子火嘴頭部84會變得相當高溫，耐久性 惡化。 因此，本實施形態中，基底部81係如上述般形成平面 20 i,灿 々狀，並且子火嘴頭部84係在由基底部81分離之狀態下設 置於基底部81之内周空間之上方。進而，由上方覆蓋基底 81之内周空間之環狀簷部84b係在與基底部81之上面之 1產生上下方向之間隙之狀態下設置於子火嘴頭部84之下 端部外周。 11 200923276 據此如第2圖之則領所示，空氣會由基底部81之内周 空間經由基底部81之上面輿詹部柳之間的間隙流動。而 且’該空氣成為二次空氣供給至由子火嘴焰孔咖喷出之混 合氣之燃燒部份。因此，可防止子火嘴焰孔84a之二次空氣 5不足造成之燃燒不良。進而，藉由在基底部81之上面與詹 部84a之間的間隙流動之空氣冷卻層部柳。因此，詹部桃 作為冷卻用之放熱扇的機能，並且可抑制子火嘴頭部料之 溫度上升。因此，可防止子火嘴頭部84之過熱造成之耐久 性惡化。 10 又，當火架5上之調理容器P產生湯汁時，湯汁會落下 於母火嘴頭部83與子火嘴頭部84之間的空間，但由於基底 部81之内周空間被簷部84b覆蓋，因此湯汁不會通過基底部 81之空間洛下於爐具本體内。而且，湯汁會經由基底部81 與母火嘴頭部83之間的各支柱部82間的空隙，由基底部81 15 排出到湯汁盛接4。 又’由於湯汁容易排出，因此基底部81上面係形成朝 徑方向外方向下方傾斜之凸面。又，簷部84b形成有插通熱 電偶10之孔84c。 以上’係參照圖式說明本發明之實施形態，但本發明 20不受限於此。例如，上述實施形態中，子火嘴焰孔84a之上 端係位於第2母火嘴焰孔83c下端之下方，但若子火嘴頭部 84之徑或輸入小時’亦可使子火嘴焰孔84a之上端位於與第 2母火嘴焰孔83c下端。

INSTRUCTIONS: [Technical Leadership of the Invention] Field of the Invention The present invention relates to a mother and child burner for a stove having a head of a female burner and a head of a burner. Conventionally, such a mother-and-child burner has been known as described in Patent Document 1. The mother and child burners are provided with a burner body, and the burner body has a base portion that is connected to the first mixing tube in an empty disk shape, and is provided with a space in the circumferential direction and is vertically disposed on the base portion. a plurality of hollow pillar portions; and a hollow annular female burner head supported by the pillar portion on the upper side of the base portion and supplied with the mixed gas from the first mixing tube via the internal space of the base portion and the internal space of the pillar portion . Further, a female burner flame hole is provided on the outer circumference of the female burner head and a cylindrical burner head is disposed in a space surrounded by the burner head, and the sub-nozzle head is connected to the second mixing tube and The base portion is integrally formed, and a sub-nozzle flame hole is provided on the outer periphery of the sub-mouth of the sub-mouth. In such a burner, the soup can be placed in the base portion and dropped into the inside of the head of the parent burner, and the soup can be prevented from falling into the body of the stove. Also, there is a soil bottom. In the case of a crucible, unlike the case where the burner body is formed into a ring shape, the burner portion cannot be supplied with secondary air to the combustion portion of the mixture which is ejected from the nozzle hole of the nozzle. In the above-mentioned burner, since the secondary air is supplied to the fire through the gap between the pillar portions between the base portion and the head portion of the female burner, the secondary air is not insufficient. Caused by poor combustion. Wherein, in the above-mentioned conventional fire nozzle, the outer peripheral portion of the bottom surface of the conditioning container placed on the top plate of the stove 5 200923276 can be produced by the combustion of the mixed gas sprayed from the flame hole of the mother burner. The mother burner is heated by the flame, and the central portion of the bottom surface of the conditioning container is heated by the burner flame hole generated by the combustion of the combined gas discharged from the nozzle of the sub-nozzle, so that the conditioning of the container 5 can be improved to some extent. Heat distribution. However, since the female fire hole and the burner flame are separated in the radial direction, the intermediate portion of the bottom surface of the conditioning container is insufficiently heated. In this case, it is considered that the second female burner flame is provided on the inner circumferential surface of the female burner, and the second female flame is generated by the combustion of the mixture discharged from the orifice. The bottom portion of the bottom surface is heated in the middle direction, and the heat distribution of the conditioning container can be raised in time. However, it is known that the following problems occur when the second female burner flame hole is set. That is, the sub-fire nozzle head is not only heated by the sub-fire nozzle but also heated by the second female burner flame hole. The ministry will become very hot and deteriorate the financial future. Further, the second air that has flowed in through the air 15 between the pillar portions between the base portion and the mother burner head is consumed by the combustion of the mixture discharged from the second mother burner flame hole, and the secondary air is consumed. It becomes impossible to supply the combustion portion of the mixed gas which is ejected from the nozzle hole of the sub-fire mouth, and the combustion is poor. [Patent Document 1] Japanese Patent Laid-Open Publication No. 5 25] No. 53 (Fig. 6) 20 [Faun " Ming Content] The subject of the invention is solved by the present invention, and the object thereof is to provide a The heat distribution of the conditioning container of the object to be heated is promptly raised, and the mother and child burners of the stove for preventing overheating or poor burning of the head of the burner are prevented. 200923276 A solution to the problem is to solve the above problems. The present invention includes a burner body, and the burner body has a hollow base portion connected to the first mixing tube, and has a circumferential direction and is erected on the base portion. And a plurality of hollow pillar portions; and the pillar portions are supported by the upper portion of the base portion, and the hollow annular female burner head portion from the air is supplied through the inner space of the base portion and the inner space of the pillar portion. Further, a first female burner flame hole is provided on the outer circumference of the female burner head, and a cylindrical burner head connected to the second mixing tube is disposed in a space surrounded by the female burner head, and is + 10 minutes outside the mouth of the burner, there is a sub-fire mouth flame hole, and in the inner circumference of the head of the mother burner, there is a second female burner flame hole. The base portion is shaped like a wire in a plan view. The mouth portion is disposed above the inner circumferential space of the base portion in a state of being separated by the base portion, and the annular crotch portion covering the inner circumferential space of the base portion from the upper portion is disposed on the outer periphery of the lower end portion of the sub-fire mouth portion, and Create an up and down direction between the top and the base 5 gaps. According to the present invention, the outer peripheral portion of the bottom surface of the conditioning container of the fire rack placed on the top plate of the stove can be heated by the first female burner flame hole generated by the combustion of the mixed gas sprayed from the flame of the first female burner. And the central portion of the abutting surface of the conditioning container is heated by a burner fire 20 generated by the combustion of the mixture of the nozzles of the burner, and the intermediate portion of the bottom surface of the conditioning container can be passed through the second female burner. The second female burner flame generated by the combustion of the mixture of the flame holes is heated. Therefore, the heat distribution of the conditioning vessel can be increased in time. Further, in the present invention, the air is caused to flow from the inner peripheral space of the base portion via the gap between the upper surface of the base portion and the crotch portion. Moreover, the air system is supplied as a portion of the air to the combustion portion of the mixture sterilized by the sub-fire nozzle. Γ=止::: The burning of the secondary air of the flame hole is not good. Furthermore, the gap between the upper part of the base part and the Zhan part flows. Therefore, the layer portion serves as a cooling fan for cooling, and the temperature of the head of the nozzle is suppressed from rising. Therefore, the deterioration of the durability caused by the overrun of the burner head can be prevented. Further, since the inner peripheral space (four) of the base portion is covered, the soup does not fall from the space of the base portion in the hearth body. I: Embodiments; J. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 10 Referring to Fig. 2, 1 is a top plate covering the upper surface of a cooker body (not shown). The top plate 1 has an opening for opening the burner 2 facing the mother-and-burner nozzle 6 of the embodiment of the present invention which is disposed on the main body, and is provided thereon. The τ member plate m is formed of a metal thick plate or a glass plate, and a gasket 3 is attached to the periphery of the opening 2 for the burner. Further, on the gasket 3, an annular soup container 4 which protrudes outward in the opening 2 15 for the burner, and a flame frame 5 are placed. Referring to Fig. 1, the mother and child burner 6 has a mixing tube unit 7 and a burner body 8. The mixing tube unit 7 has a first mixing tube unit 71 and a second mixing tube 72. The downstream end of the first mixing tube 71 is formed with a distribution chamber portion 73 having an inner and outer double cylinder structure rising toward the inner peripheral space of the soup container 4. The second mixing tube 72 is integrated with the first mixing tube 71 in the bottom surface of the front side (the left side of the second drawing) of the distribution chamber portion 203. The burner body 8 has a planar annular hollow base portion 81 having an outer diameter larger than the inner diameter of the soup container 4; and a plurality of hollow pillar portions 82 spaced apart from each other on the base portion 81 in the circumferential direction; The hollow annular valve head portion 83 supported on the upper side of the base portion 81 via the pillar portions 82 and the cylindrical burner tip portion 84 disposed in the space surrounded by the mouth portion 83 of the parent flame 200923276 are provided. The flow-reducing person σ8ι connected to the distribution portion 73 is disposed below the base portion 8丨, and suspends the cutter tube 73e from the inner cylinder portion 73a of the distribution chamber portion 73 and the seal cylinder 481b 81c of the outer cylinder portion 73b. It is located on the inner peripheral side and the outer peripheral side of the inflow port 81a. Further, the mixture gas (the mixture of the _(four) and the lapse line) from the first stage tube 7! is supplied from the inlet 81a to the mother burner head 83 via the internal space of the base portion 81 and the internal space of each of the pillar portions 82. The interior space. The female burner head portion 83 has a bottom portion 81 formed by the base portion 81 and the pillar portion 82, and an upper half portion (7) formed by a burner cover 83a detachably placed in the lower half portion. Most of them are suspended below the burner cover 83a and are located at the outer and inner peripheral portions, respectively. Further, the outer periphery of the female burner head 83 is provided on the outer circumference of the burner cover. The first female burner flame hole 83b formed by the gap between the teeth of the crucible, and the second parent flame formed by the gap between the teeth of the outer periphery of the burner nozzle Mouth flame hole 83c. Further, the mixture gas supplied to the (five) of the mother flame is composed of the first mother fire hole 83b and the second mother flame hole 83c. Also formed around the burner cover 83a is attached to the burner. The ignition switch 9 of the 6 is opposite to the trunk portion 83d. Moreover, by the igniting discharge between the ignition switch 9 and the singer, the squirting gas from the first female burner flame hole 83d is ignited and then borrowed from the first female burner. The combustion of the mixture of the flame holes 83b generates the first female burner fire-breathing Fa. In the upper surface i of the burner, a groove-shaped flame hole extending from the outer circumference toward the inner side in the radial direction is formed. The fire is fired by the first female fire; tia Fa ignites the fire from the second female burner mouth 83 by means of a flame hole, and the mixture is sprayed out from the second parent burner flame hole 8乂200923276. The combustion of the gas generates the second mother burner flame pb. Further, the secondary air is supplied from the outside of the burner body 8 to the combustion portion of the mixture discharged from the second mother burner nozzle hole 83b, and The air is supplied from the outside of the burner body 8 via the gap between the pillar portions 58 between the base portion 81 and the female burner head 83. The combustion portion of the mixed gas ejected from the second female burner flame hole 83c. The mouth/sub-nozzle head portion 84 is fitted and connected to the second mixing tube 72 in which the gap is inserted in the inner peripheral space of the base portion 81. The lower end portion of the sub-nozzle hole 8 is disposed outside the sub-nozzle head 84. The mixture of the second mixture f is supplied to the internal space of the sub-nozzle head 84 1〇 by the sub-fire nozzle flame hole 84a After the mouth is ignited, the 母 is ignited by the flame of the second female burner flame Fb, and the combustion of the mixture is generated by the combustion of the mixture from the mouth of the nozzle of the burner, and then the flame is generated near the head of the burner. The thermocouple 10 for flame detection arranged in one place is heated by a sub-fire nozzle flame, and the electromagnetic safety valve (not shown) in which the first and second mixing tubes 71 and 72 are installed in the gas supply path 5 is borrowed. The electric power of the thermocouple 10 is kept open. The upper burner flame hole 84a is disposed at an upper end thereof below the lower end of the second female burner bore 83c. Further, it is formed with the burner flame hole 84a of the thermocouple 10. It is lower than the other sub-fire nozzle holes 84a. Thus, the sub-fire nozzle flame hole 84a is disposed under the second female burner flame hole 83c. The lower position, therefore, even if the shape of the container P is curved like the bottom surface of the Chinese cooking pot, the distance between the burner hole 84a and the bottom surface of the conditioning container p is not too short. When the sub-flame flame Fc rises upward and is narrow to a certain extent, it reaches the central portion of the bottom surface of the conditioning container P and the central portion of the bottom surface of the conditioning container P is heated by the sub-flame flame Fc plus 200923276. It is possible to suppress expansion beyond the flame of the sub-nozzle, and the second female burner flame hole 83c is present at a position higher than the burner flame hole 84a, so the second female burner flame Fb is not due to the sub-flame flame Fc. The upper portion in the radial direction of the bottom surface of the conditioning container P is heated by the second female burner fire feFb. Further, the outer peripheral portion of the bottom surface of the container p is heated by the second mother burner flame. Thereby, the heat distribution of the conditioning container P can be increased in time. In addition, when the 'second female fire flame quilt flame is pressed from above, the second female fire flame will become a flame shape of the pressure along the upper surface of the female burner head 83, and the female burner head 83 is The second female burner flame becomes a hot high temperature, and the durability is deteriorated. On the other hand, in the present embodiment, the second female burner flame Fb is not raised by the upper sub-nozzle flame Fc from above, so that the second female burner flame can be prevented from causing the female burner. The overheating of the portion 83 prevents deterioration of durability. Further, it is also considered that the base portion 81 is formed into a hollow disk shape, and the sub-fired head portion 84 is formed in a central portion of the upper surface thereof. However, in this case, the supply of the combustion portion of the mixture of the second-under air which is ejected from the nozzle hole 84a is likely to be insufficient, and the sub-nozzle head 84 becomes relatively high in temperature and the durability is deteriorated. Therefore, in the present embodiment, the base portion 81 is formed into a flat surface 20 i as described above, and the sub-nozzle head portion 84 is provided in the inner peripheral space of the base portion 81 in a state of being separated by the base portion 81. Above. Further, the annular flange portion 84b covering the inner circumferential space of the base 81 is provided on the outer periphery of the lower end portion of the sub-nozzle head portion 84 in a state in which the upper surface of the base portion 81 is vertically spaced. 11 200923276 Accordingly, as shown in Fig. 2, the air flows from the inner circumferential space of the base portion 81 through the gap between the upper surface of the base portion 81 and the tantalum. Moreover, the air is supplied to the combustion portion of the mixed gas which is ejected from the nozzle of the burner. Therefore, it is possible to prevent the combustion of the secondary air 5 of the sub-burner flame hole 84a from being insufficient. Further, the layer portion is cooled by the air flowing in the gap between the upper surface of the base portion 81 and the portion 84a. Therefore, Zhan Butao is the function of the heat release fan for cooling, and can suppress the temperature rise of the sub-nozzle head material. Therefore, the durability caused by the overheating of the sub-nozzle head 84 can be prevented from deteriorating. Further, when the conditioning container P on the fire frame 5 produces the broth, the broth falls into the space between the female burner head 83 and the sub-fire mouth head 84, but since the inner peripheral space of the base portion 81 is The crotch portion 84b is covered, so that the soup does not pass through the space of the base portion 81 and is lowered into the hearth body. Further, the broth is discharged from the base portion 81 15 to the soup receiving portion 4 via the gap between the base portions 81 between the base portion 81 and the female burner head portion 83. Further, since the soup is easily discharged, the upper surface of the base portion 81 is formed to have a convex surface which is inclined downward in the outer direction in the radial direction. Further, the flange portion 84b is formed with a hole 84c through which the thermocouple 10 is inserted. The embodiments of the present invention have been described above with reference to the drawings, but the present invention 20 is not limited thereto. For example, in the above embodiment, the upper end of the sub-fire nozzle flame hole 84a is located below the lower end of the second female burner flame hole 83c, but if the diameter or input of the sub-nozzle head 84 is small, the sub-fire nozzle flame hole can also be used. The upper end of the 84a is located at the lower end of the second female burner flame hole 83c.
