そして、図２，３は、テーブルこんろにおける両面焼きのガスグリルにグリル用バーナ１を用いた例を示すもので、グリル庫１０内では、グリル用バーナ１，１を焼網１１の下部で互いに対向するように、且つノズル部５ａがグリル庫１０の手前側（図３の下側）となるように左右対称に配置される。１２，１２は、グリル用バーナ１の下部へ一体に取り付けられ、ノズル部５ａ〜５ｆの開口際に保炎用炎孔１３を位置させる保炎用バーナ、１４，１４は、焼網１１の上部左右に取り付けられる上バーナで、焼網１１の下方には受皿１５が備えられ、グリル庫１０の最奥の仕切板１６には、排気孔１７が形成されている。尚、ノズル部５ｆは、グリル庫１０の奥側に位置して、図示しないガイド板で炎を上向きに形成させて上バーナ１４へ火移りさせるためのもので、加熱調理には寄与しない。
【０００９】
以上の如く構成されたガスグリルにおいては、テーブルこんろ前面に設けられた図示しない点火ボタンを押し操作すると、ガス流路を開閉する電磁弁が開弁され、各グリル用バーナ１のノズルパイプ７から各ノズル部５ａ〜５ｆへガスが供給される。このとき、各ノズル部５ａ〜５ｆにおいては、狭いノズル孔ｄ１〜ｄ６をガスが高速で通過する際のインジェクション効果により、空気孔６，６から夫々一次空気を吸引し、燃料ガスとして噴出される。一方、点火操作により保炎用バーナ１２，１２へも燃料ガスが供給されて点火装置の作動によって点火するため、各ノズル部５ａ〜５ｆから噴出される燃料ガスに順に引火し、各ノズル部５ａ〜５ｆの開口から炎を生じさせる。この炎は、ガスの供給圧力を利用した速い噴出速度により前方へ長く形成される。
【００１０】
そして、各ノズル部５ａ〜５ｅにおいては、焼網１１下部におけるグリル庫１０内の温度分布が均一になるように、ノズル孔ｄ１〜ｄ５の径を変えて、図３に示すようにノズル部５ごとに形成される炎Ｆ，Ｆ・・の長さを調節しているため、調理物１８，１８の裏面に焼きムラが生じることが少なく、見栄えの良い調理が可能となる。
又、ここでは、グリル用バーナ１におけるノズル部５ａ〜５ｅの間隔を手前側が密、奥側が疎となるように形成しているから、手前側の密のノズル部５ａ，５ｂ等によって加熱された熱気がグリル庫１０後方の排気孔１７へ流れることでグリル庫１０内の温度分布をより均一化でき、調理物１８，１８裏面の焼きムラを効果的に抑えることができる。よって、後方排気タイプのガスグリルにおいて好適に使用できる。
更に、グリル用バーナ１におけるノズル部５ｆを最奥に配置して、上バーナ１４への火移り用としたことで、一本のグリル用バーナ１で調理物の加熱調理と火移りとが行える合理的な構成となる。
【００１１】
尚、ノズル孔の径は、ガス種、ノズル部の数や大きさ、グリル庫の大きさ等の条件によって適宜変更できる。上記表１では２種類の径を採用しているが、ノズル部ごとに全く異なるように変えても良い。又、グリル用バーナを左右に配置する場合、必ずしもノズル孔も左右対称とする必要はなく、温度分布の均一化が図れれば、ノズル孔の径は勿論、ノズル部の位置も左右で千鳥状に変えたりして差し支えない。
又、グリル用バーナは、上記形態のようにプレス成形によるものに限らず、パイプ部とノズル部とを夫々単独で形成し、パイプ部にノズル部を螺合させる等して両者を一体化する構造でも本発明は適用可能である。この場合、ノズル孔はノズル部内のガス通路に形成すれば良い。
【００１２】
更に、グリル用バーナは、グリル庫内の左右に配置した例で説明しているが、ノズル孔の設定若しくはノズル部の間隔の設定によっては、グリル庫内の片側にのみ設けることができる。
一方、上記形態では、ノズル孔の径を変える発明と、ノズル部の間隔を変える発明とを同時に適用した例で説明したが、ノズル部の間隔の設定のみで温度分布の均一化を図ることは勿論可能である。但し、上記のように両発明を適用することで温度分布の均一化はより促進されて焼きムラは一層少なくなり、調理性能に優れた好ましい形態となる。又、火移り用のノズル部も、１つに限らず、他のバーナとの関係によっては複数あっても差し支えない。
【００１３】
【発明の効果】
請求項１に記載の発明によれば、ノズル部の間隔を、ガスグリル内への設置状態で手前側が狭く、奥側が広くなるように設定したことで、後方排気タイプのガスグリル内を均等に加熱でき、調理物の焼きムラを効果的に抑えることができる。
請求項２に記載の発明によれば、請求項１の効果に加えて、ガスグリル内への設置状態で温度分布が均一になるように、ノズル孔の径をノズル部ごとに設定して炎の長さを調節したことで、ガスグリル内を均等に加熱でき、調理物の焼きムラを効果的に抑えることができる。
請求項３に記載の発明によれば、請求項１又は２の効果に加えて、ガスグリル内の加熱用のノズル部に加えて、ガスグリルへの設置状態で他のバーナへ火移り可能な火移り用のノズル部を適宜位置に設けたことで、一本のグリル用バーナで調理物の加熱調理とグリル庫内の他のバーナへの火移りとが共に可能な合理的な構成となる。
請求項４に記載の発明によれば、両面焼きのガスグリルにおいて、下バーナを請求項１乃至３の何れかに記載のグリル用バーナとして、グリル庫内の前後方向に配置したことで、調理物に生じる焼きムラが少なくなり、見栄えの良い調理が可能となる。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory view of a grill burner (upper is a plane, lower is a front), and the grill burner 1 communicates with a tubular portion 4 extending over the entire length in the longitudinal direction and orthogonally to the tubular portion 4. The cylindrical nozzle portions 5a to 5f are formed by press forming and caulking and joining the upper plate 2 and the lower plate 3. Air holes 6 and 6 are formed above and below the nozzle portions 5a to 5f. ing. In addition, here, the interval W1 between the nozzle portions 5a and 5b and the nozzle portions 5b and 5c is made narrower than the interval W2 between the nozzle portions 5c and 5d and the nozzle portions 5d and 5e, and as it goes to the left side. The nozzle part is set to be dense.
On the other hand, a nozzle pipe 7 is inserted into the cylindrical part 4 as a pipe part whose front end is closed and whose base end is connected to the gas pipe. On the side surface of the nozzle pipe 7, small-diameter nozzle holes d <b> 1 to d <b> 6 that are located at the centers of the nozzle portions 5 a to 5 f in a state where the nozzle pipe 7 is housed are formed. The nozzle holes d1 to d6 are not all the same opening area, but by adjusting the length of the flame by setting the opening area independently (the larger the opening area, the longer the flame is formed), the inside of the grill For example, in the case of LP gas, the temperature distribution is set as shown in Table 1 below. However, since the nozzle hole d6 is used for fire transfer as described later, unlike the other nozzle holes d1 to d5 for cooking, the nozzle hole d6 may be appropriately set to a diameter suitable for fire transfer.
[0007]
[Table 1]

[0008]
FIGS. 2 and 3 show an example in which the grill burner 1 is used for a double-sided gas grill on a table stove. In the grill cabinet 10, the grill burners 1 and 1 are connected to each other below the grill 11. The nozzle parts 5a are arranged symmetrically so as to face each other and to be on the front side (lower side in FIG. 3) of the grill 10. 12 and 12 are integrally attached to the lower portion of the grill burner 1, and the flame-holding burner for positioning the flame-holding flame hole 13 when the nozzle portions 5 a to 5 f are opened. An upper burner attached to the left and right, a tray 15 is provided below the grill 11, and an exhaust hole 17 is formed in the innermost partition plate 16 of the grill cabinet 10. In addition, the nozzle part 5f is located in the back | inner side of the grill warehouse 10, and is for making a flame face upward with a guide plate which is not illustrated and transferring it to the upper burner 14, and does not contribute to cooking.
[0009]
In the gas grill configured as described above, when an ignition button (not shown) provided on the front surface of the table stove is pressed, an electromagnetic valve for opening and closing the gas flow path is opened, and the nozzle pipe 7 of each grill burner 1 is opened. Gas is supplied to each nozzle part 5a-5f. At this time, in each nozzle part 5a-5f, primary air is each suck | inhaled from the air holes 6 and 6 by the injection effect at the time of gas passing through the narrow nozzle holes d1-d6 at high speed, and it ejects as fuel gas. . On the other hand, since the fuel gas is also supplied to the flame holding burners 12 and 12 by the ignition operation and ignited by the operation of the ignition device, the fuel gas ejected from the nozzle portions 5a to 5f is ignited in order, and each nozzle portion 5a. A flame is generated from the opening of ˜5f. This flame is formed long in the forward direction due to a high ejection speed utilizing the gas supply pressure.
[0010]
And in each nozzle part 5a-5e, the diameter of the nozzle holes d1-d5 is changed so that the temperature distribution in the grill warehouse 10 in the lower part of the grill 11 may become uniform, and as shown in FIG. Since the lengths of the flames F, F, formed each time are adjusted, uneven cooking is less likely to occur on the back surfaces of the cooked items 18, 18 and cooking with good appearance becomes possible.
Further, here, the interval between the nozzle portions 5a to 5e in the grill burner 1 is formed so that the front side is dense and the back side is sparse, so that it is heated by the dense nozzle portions 5a and 5b on the front side. Since the hot air flows to the exhaust hole 17 at the rear of the grill 10, the temperature distribution in the grill 10 can be made more uniform, and the uneven baking on the back surfaces of the food products 18 and 18 can be effectively suppressed. Therefore, it can be suitably used in a rear exhaust type gas grill.
Further, the nozzle portion 5f in the grill burner 1 is disposed at the innermost position for use in transferring the fire to the upper burner 14, so that cooking and cooking of the food can be performed with one grill burner 1. Reasonable composition.
[0011]
The diameter of the nozzle hole can be appropriately changed according to conditions such as the gas type, the number and size of the nozzle portions, and the size of the grill box. In Table 1 above, two types of diameters are employed, but the diameters may be completely different for each nozzle portion. In addition, when the grill burner is arranged on the left and right, the nozzle holes do not necessarily have to be symmetrical, and if the temperature distribution can be made uniform, the nozzle hole diameter and the nozzle position are staggered on both sides. You can change it.
Further, the grill burner is not limited to press-molding as in the above embodiment, and the pipe portion and the nozzle portion are formed independently, and the both are integrated by screwing the nozzle portion into the pipe portion. The present invention can also be applied to a structure. In this case, the nozzle hole may be formed in the gas passage in the nozzle portion.
[0012]
Furthermore, although the grill burner is described as an example in which the grill burner is arranged on the left and right in the grill cabinet, it can be provided only on one side in the grill cabinet depending on the setting of the nozzle holes or the interval of the nozzle portions.
On the other hand, in the above embodiment, the invention in which the invention for changing the diameter of the nozzle hole and the invention for changing the interval of the nozzle part are applied at the same time has been described, but it is possible to make the temperature distribution uniform only by setting the interval of the nozzle part. Of course it is possible. However, by applying both the inventions as described above, the uniformity of the temperature distribution is further promoted and baking unevenness is further reduced, which is a preferable form excellent in cooking performance. Further, the number of nozzles for transferring fire is not limited to one, and a plurality of nozzles may be used depending on the relationship with other burners.
[0013]
【The invention's effect】
According to the first aspect of the present invention, the interval between the nozzle portions is set so that the front side is narrow and the back side is wide when installed in the gas grill, so that the rear exhaust type gas grill can be heated evenly. , Uneven baking of cooked foods can be effectively suppressed.
According to the second aspect of the present invention, in addition to the effect of the first aspect, the diameter of the nozzle hole is set for each nozzle portion so that the temperature distribution is uniform in the installed state in the gas grill. By adjusting the length, the inside of the gas grill can be heated evenly, and uneven baking of the cooked product can be effectively suppressed.
According to the third aspect of the present invention, in addition to the effect of the first or second aspect, in addition to the heating nozzle portion in the gas grill, a fire transfer that can be transferred to another burner in the installed state in the gas grill. By providing the nozzle portion for use at an appropriate position, it is possible to achieve a rational configuration that enables both cooking of cooked food and transfer to other burners in the grill cabinet with a single grill burner.
According to the fourth aspect of the present invention, in the double-side grill gas grill, the lower burner is disposed as the grill burner according to any one of the first to third aspects in the front-rear direction in the grill cabinet, so that the cooked food is obtained. This reduces cooking unevenness and makes it possible to cook with good appearance.
