図３〜図５を参照し、ガバナ装置１００について説明する。ガバナ装置１００は、筐体２内の隙間領域Ｇ１に配置される。ガバナ装置１００は燃料供給装置５２に連結し、燃料供給装置５２から供給されるガス圧を調整することにより、安定したガス圧で、ガスをグリルバーナへ供給するための装置である。本実施形態のガバナ装置１００は燃料供給装置５２の上側に配置され、後側本体５２Ｂの流出口６５から流出するガスを内部に導入し、導入したガスを調圧してグリルバーナに供給する。 The governor device 100 will be described with reference to FIGS. 3 to 5. The governor device 100 is arranged in the gap region G1 in the housing 2. The governor device 100 is a device for supplying gas to the grill burner at a stable gas pressure by connecting to the fuel supply device 52 and adjusting the gas pressure supplied from the fuel supply device 52. The governor device 100 of the present embodiment is arranged above the fuel supply device 52, introduces the gas flowing out from the outlet 65 of the rear main body 52B into the inside, adjusts the pressure of the introduced gas, and supplies the introduced gas to the grill burner.

ガバナ装置１００は、ガスガバナ１１０とガス分配装置１２０を一体に設けた装置である。ガスガバナ１１０は、燃料供給装置５２から供給されるガスの供給圧を調圧する。ガス分配装置１２０は、ガスガバナ１１０が調圧したガスの流量を電磁弁１７１，１７２によって切り替え、上火バーナ３２及び下火バーナ３３の夫々に分配して供給する。 The governor device 100 is a device in which a gas governor 110 and a gas distribution device 120 are integrally provided. The gas governor 110 regulates the supply pressure of the gas supplied from the fuel supply device 52. The gas distribution device 120 switches the flow rate of the gas regulated by the gas governor 110 by the solenoid valves 171 and 172, and distributes and supplies the gas to the upper heat burner 32 and the lower heat burner 33, respectively.

ガスガバナ１１０は公知であるので詳細な説明は省略するが、内部に調圧バネ１１１、弁体１１２、ダイヤフラム１１３、圧力室１１４等を備える。弁体１１２は、調圧バネ１１１の付勢により、弁を開く向きに押圧される。ダイヤフラム１１３は、弁体１１２の軸部に連結する。燃料供給装置５２の流出口６５から供給されるガスは、流出口６５に接続する流入口１１５から圧力室１１４内に流入する。ダイヤフラム１１３は、圧力室１１４内のガス圧が高くなるに従い、バネ圧に抗して弁を閉じる向きに弁体１１２を動かす。ガスガバナ１１０は、流入口１１５のガス圧が変化しても、流出口１１６からガス分配装置１２０へ送出するガス圧が略一定となるように、圧力室１１４内のガス圧を調圧する。 Since the gas governor 110 is known, detailed description thereof will be omitted, but a pressure regulating spring 111, a valve body 112, a diaphragm 113, a pressure chamber 114, and the like are provided therein. The valve body 112 is pressed in the direction of opening the valve by the urging of the pressure adjusting spring 111. The diaphragm 113 is connected to the shaft portion of the valve body 112. The gas supplied from the outflow port 65 of the fuel supply device 52 flows into the pressure chamber 114 from the inflow port 115 connected to the outflow port 65. The diaphragm 113 moves the valve body 112 in the direction of closing the valve against the spring pressure as the gas pressure in the pressure chamber 114 increases. The gas governor 110 regulates the gas pressure in the pressure chamber 114 so that the gas pressure sent from the outflow port 116 to the gas distribution device 120 becomes substantially constant even if the gas pressure at the inflow port 115 changes.

前述したように、上火ガス管３５の上流端部３５Ａと下火ガス管３６の上流端部３６Ａは、夫々、ガス分配装置１２０の基体１３０の右面１３４に開口する上火供給口１５３と下火供給口１５４に挿入される。基体１３０において、上火供給口１５３は下火供給口１５４の上方に設けられており、上火供給口１５３と下火供給口１５４は、共に右方へ向けて開口する。上流端部３５Ａ，３６Ａは、上火供給口１５３、下火供給口１５４の夫々に対して左方へ向けて挿入される。 As described above, the upstream end portion 35A of the upper fire gas pipe 35 and the upstream end portion 36A of the lower fire gas pipe 36 are the upper fire supply port 153 and the lower portion that open to the right side 134 of the base 130 of the gas distribution device 120, respectively. It is inserted into the fire supply port 154. In the base 130, the upper fire supply port 153 is provided above the lower fire supply port 154, and both the upper fire supply port 153 and the lower fire supply port 154 open to the right. The upstream end portions 35A and 36A are inserted toward the left with respect to the upper fire supply port 153 and the lower fire supply port 154, respectively.

筐体２内で、ガバナ装置１００は燃料供給装置５２の上に組み付けられる。筐体２内において、上火スロート部３７の開口部は、上火供給口１５３の後方、且つ略同じ高さ位置にある。故に、上火ガス管３５の中間部分は略前後方向に延び、上流端部３５Ａ及び下流端部３５Ｂが中間部分に対して夫々左方に屈曲する。上火ガス管３５は、上方から見て略コの字形状を呈する。 In the housing 2, the governor device 100 is assembled on the fuel supply device 52. In the housing 2, the opening of the upper fire throat portion 37 is located behind the upper fire supply port 153 and at substantially the same height position. Therefore, the intermediate portion of the upper fire gas pipe 35 extends substantially in the front-rear direction, and the upstream end portion 35A and the downstream end portion 35B bend to the left with respect to the intermediate portion, respectively. The upper fire gas pipe 35 has a substantially U-shape when viewed from above.

筐体２内において、下火スロート部３８の開口部は、下火供給口１５４の後方、且つ高さ位置が下火供給口１５４よりも下方にある。故に、下火ガス管３６の中間部分は前後方向に延びる部分と上下方向に延びる部分とが屈曲により接続され、上流端部３６Ａ及び下流端部３６Ｂが中間部分に対して夫々左方に屈曲する。下火ガス管３６は、上方から見て略コの字形状を呈する。 In the housing 2, the opening of the lower fire throat portion 38 is behind the lower fire supply port 154 and the height position is lower than the lower fire supply port 154. Therefore, in the intermediate portion of the lower heat gas pipe 36, the portion extending in the front-rear direction and the portion extending in the vertical direction are connected by bending, and the upstream end portion 36A and the downstream end portion 36B are respectively bent to the left with respect to the intermediate portion. .. The lower fire gas pipe 36 has a substantially U-shape when viewed from above.

上火ガス管３５及び下火ガス管３６の組み付けは、下火ガス管３６が上火ガス管３５よりも先に行われる。図６に示すように、下火ガス管３６は、上流端部３６Ａ及び下流端部３６Ｂが中間部分から屈曲する方向を左方に向けて、ガバナ装置１００の右上方に配置される。下火ガス管３６は隙間領域Ｇ１内に下ろされ、ガバナ装置１００の右方に配置される。上流端部３６Ａの軸は下火供給口１５４の軸に揃えられ、下流端部３６Ｂの軸は下火スロート部３８の開口部分の中央に配置される。下火ガス管３６は、管全体が左方へ移動される。上流端部３６Ａは、下火供給口１５４に挿入され、下流端部３６Ｂの噴射口は、下火スロート部３８の開口部分に対峙して配置される。 Assembling the upper heat gas pipe 35 and the lower heat gas pipe 36 is performed before the lower heat gas pipe 36 is assembled. As shown in FIG. 6, the lower fire gas pipe 36 is arranged on the upper right side of the governor device 100 with the upstream end portion 36A and the downstream end portion 36B bent from the intermediate portion to the left. The lower fire gas pipe 36 is lowered into the gap region G1 and is arranged on the right side of the governor device 100. The shaft of the upstream end portion 36A is aligned with the shaft of the lower fire supply port 154, and the shaft of the downstream end portion 36B is arranged at the center of the opening portion of the lower fire throat portion 38. The entire lower fire gas pipe 36 is moved to the left. The upstream end portion 36A is inserted into the lower fire supply port 154, and the injection port of the downstream end portion 36B is arranged so as to face the opening portion of the lower fire throat portion 38.

次に、上火ガス管３５は、上流端部３５Ａ及び下流端部３５Ｂが中間部分から屈曲する方向を左方に向けて、ガバナ装置１００の右上方に配置される。上火ガス管３５は隙間領域Ｇ１内に下ろされ、ガバナ装置１００の右方に配置される。上流端部３５Ａの軸は下火供給口１５４の軸に揃えられ、下流端部３５Ｂの軸は上火スロート部３７の開口部分の中央に配置される。上火ガス管３５は、管全体が左方へ移動される。上流端部３５Ａは、上火供給口１５３に挿入され、下流端部３５Ｂの噴射口は、上火スロート部３７の開口部分に対峙して配置される。 Next, the upper fire gas pipe 35 is arranged on the upper right side of the governor device 100 so that the upstream end portion 35A and the downstream end portion 35B bend from the intermediate portion to the left. The upper fire gas pipe 35 is lowered into the gap region G1 and is arranged on the right side of the governor device 100. The shaft of the upstream end portion 35A is aligned with the shaft of the lower fire supply port 154, and the shaft of the downstream end portion 35B is arranged at the center of the opening portion of the upper fire throat portion 37. The entire upper fire gas pipe 35 is moved to the left. The upstream end portion 35A is inserted into the upper fire supply port 153, and the injection port of the downstream end portion 35B is arranged so as to face the opening portion of the upper fire throat portion 37.

図４に示すように、基体１３０の右面１３４に抜け防止のための保持金具１３９が嵌められ、固定ネジ１４０で基体１３０に固定されることによって、上火ガス管３５の上流端部３５Ａと、下火ガス管３６の上流端部３６Ａは、基体１３０から抜け止めされる。また、図２に示すように、下流端部３５Ｂ及び下流端部３６Ｂは、上火スロート部３７及び下火スロート部３８の左側に設けられた固定部（図示略）に、夫々組み付けられる。 As shown in FIG. 4, a holding metal fitting 139 for preventing disconnection is fitted to the right side 134 of the base 130, and is fixed to the base 130 with a fixing screw 140 to form an upstream end portion 35A of the upper fire gas pipe 35 and The upstream end portion 36A of the lower heat gas pipe 36 is prevented from coming off from the base 130. Further, as shown in FIG. 2, the downstream end portion 35B and the downstream end portion 36B are respectively assembled to the fixed portions (not shown) provided on the left side of the upper fire throat portion 37 and the lower fire throat portion 38.

以上説明したように、ガバナ装置１００とグリル庫３１との間に上火ガス管３５を配設する場合に、上火ガス管３５の上流端部３５Ａを上火供給口１５３に接続する方向と、下流端部３５Ｂを上火スロート部３７に接続する方向は共に同じ方向であり、左右方向の左側を向く方向である。故に筐体２内に上火ガス管３５を組み付けるとき、上火ガス管３５の上流端部３５Ａを上火供給口１５３に向け、下流端部３５Ｂを上火スロート部３７に向けた状態で、上火ガス管３５の全体を左右方向の左側に移動させればよいので、上火ガス管３５の位置決めが容易であり、筐体２内で上火ガス管３５を容易に配設することができる。また、上火ガス管３５の接続作業において、上火ガス管３５の上流端部３５Ａを上火供給口１５３に差し込む作業と、下流端部３５Ｂを上火スロート部３７の開口部分に対峙する位置に配置する作業とを、上火ガス管３５に曲げや捻り等の負荷をかけずに行うことができる。そして、上火ガス管３５は、例えば、上流端部３５Ａと下流端部３５Ｂを、両端部を繋ぐ中間部分に対して同一方向に折り曲げ、コの字状に形成すればよいので、製造が容易である。 As described above, when the upper heat gas pipe 35 is arranged between the governor device 100 and the grill storage 31, the direction in which the upstream end portion 35A of the upper heat gas pipe 35 is connected to the upper heat supply port 153 is defined. , The direction of connecting the downstream end portion 35B to the upper fire throat portion 37 is the same direction, and is the direction facing the left side in the left-right direction. Therefore, when assembling the upper fire gas pipe 35 in the housing 2, the upstream end 35A of the upper fire gas pipe 35 is directed to the upper fire supply port 153, and the downstream end 35B is directed to the upper fire throat 37. Since the entire upper fire gas pipe 35 may be moved to the left in the left-right direction, the upper fire gas pipe 35 can be easily positioned, and the upper fire gas pipe 35 can be easily arranged in the housing 2. it can. Further, in the connection work of the upper fire gas pipe 35, the work of inserting the upstream end portion 35A of the upper fire gas pipe 35 into the upper fire supply port 153 and the position where the downstream end portion 35B faces the opening portion of the upper fire throat portion 37. It is possible to carry out the work of arranging the upper heat gas pipe 35 without applying a load such as bending or twisting to the upper heat gas pipe 35. The upper fire gas pipe 35 can be easily manufactured because, for example, the upstream end portion 35A and the downstream end portion 35B may be bent in the same direction with respect to the intermediate portion connecting both ends to form a U shape. Is.

下火ガス管３６を配設する場合についても同様である。すなわち、下火ガス管３６の上流端部３６Ａを下火供給口１５４に接続する方向と、下流端部３６Ｂを下火スロート部３８に接続する方向は共に同じ方向であり、左右方向の左側を向く方向である。故に筐体２内に下火ガス管３６を組み付けるとき、下火ガス管３６の上流端部３６Ａを下火供給口１５４に向け、下流端部３６Ｂを下火スロート部３８に向けた状態で、下火ガス管３６の全体を左右方向の左側に移動させればよいので、下火ガス管３６の位置決めが容易であり、筐体２内で下火ガス管３６を容易に配設することができる。また、下火ガス管３６の接続作業において、下火ガス管３６の上流端部３６Ａを下火供給口１５４に差し込む作業と、下流端部３６Ｂを下火スロート部３８の開口部分に対峙する位置に配置する作業とを、下火ガス管３６に曲げや捻り等の負荷をかけずに行うことができる。そして、下火ガス管３６は、例えば、上流端部３６Ａと下流端部３６Ｂを、両端部を繋ぐ中間部分に対して同一方向に折り曲げ、コの字状に形成すればよいので、製造が容易である。 The same applies to the case where the lower heat gas pipe 36 is arranged. That is, the direction in which the upstream end 36A of the lower fire gas pipe 36 is connected to the lower fire supply port 154 and the direction in which the downstream end 36B is connected to the lower fire throat 38 are both in the same direction, and the left side in the left-right direction is The direction to face. Therefore, when assembling the lower heat gas pipe 36 in the housing 2, the upstream end 36A of the lower heat gas pipe 36 is directed to the lower fire supply port 154, and the downstream end 36B is directed to the lower fire throat 38. Since the entire lower heat gas pipe 36 may be moved to the left side in the left-right direction, the lower heat gas pipe 36 can be easily positioned, and the lower heat gas pipe 36 can be easily arranged in the housing 2. it can. Further, in the connection work of the lower fire gas pipe 36, the work of inserting the upstream end portion 36A of the lower fire gas pipe 36 into the lower fire supply port 154 and the position where the downstream end portion 36B faces the opening portion of the lower fire throat portion 38. The work of arranging the lower heat gas pipe 36 can be performed without applying a load such as bending or twisting to the lower heat gas pipe 36. The lower fire gas pipe 36 can be easily manufactured because, for example, the upstream end portion 36A and the downstream end portion 36B may be bent in the same direction with respect to the intermediate portion connecting both ends to form a U shape. Is.

また、上火ガス管３５と下火ガス管３６を筐体２内で共に同じ方向（左右方向の左側）に移動させることでガバナ装置１００及びグリル庫３１に接続できるので、筐体２内で上火ガス管３５と下火ガス管３６を容易に配設することができる。 Further, since the upper heat gas pipe 35 and the lower heat gas pipe 36 can be connected to the governor device 100 and the grill storage 31 by moving both in the housing 2 in the same direction (left side in the left-right direction), the upper heat gas pipe 35 and the lower heat gas pipe 36 can be connected in the housing 2. The upper heat gas pipe 35 and the lower heat gas pipe 36 can be easily arranged.

更に、上火ガス管３５と下火ガス管３６の組み付け時の移動方向を左右方向に限定できるので、筐体２内で他の部品に干渉しにくく、筐体２内で上火ガス管３５と下火ガス管３６を容易に配設することができる。 Further, since the moving direction when the upper heat gas pipe 35 and the lower heat gas pipe 36 are assembled can be limited to the left and right directions, it is less likely to interfere with other parts in the housing 2, and the upper heat gas pipe 35 in the housing 2 And the lower heat gas pipe 36 can be easily arranged.

下火供給口１５４、下火スロート部３８は、夫々、上火供給口１５３、上火スロート部３７の下方にある。故に、上火ガス管３５と下火ガス管３６は、夫々がガバナ装置１００とグリル庫３１に接続した状態で、互いに交差しない。よってガスコンロ１の製造時には、下火ガス管３６を配設してから上火ガス管３５を配設すればよく、筐体２内で上火ガス管３５と下火ガス管３６を容易に配設することができる。 The lower fire supply port 154 and the lower fire throat portion 38 are located below the upper fire supply port 153 and the upper fire throat portion 37, respectively. Therefore, the upper heat gas pipe 35 and the lower heat gas pipe 36 do not intersect with each other in a state where they are connected to the governor device 100 and the grill storage 31, respectively. Therefore, at the time of manufacturing the gas stove 1, the lower heat gas pipe 36 may be arranged and then the upper heat gas pipe 35 may be arranged, and the upper heat gas pipe 35 and the lower heat gas pipe 36 may be easily arranged in the housing 2. Can be set up.

右面１３４の開口部分が上火供給口１５３として機能する上流路１４３と、右面１３４の開口部分が下火供給口１５４として機能する下流路１４４は、共に、基体１３０を左右方向に貫通する。基体１３０を金型で成型するとき、上流路１４３と下流路１４４を形成する中子によって上火供給口１５３と下火供給口１５４を形成すれば、夫々の開口方向を、左右方向の右側へ向けて精確に形成することができる。また、ガスガバナ１１０を主流路１４１が延びる前後方向に沿って配置できるので、上火ガス管３５と下火ガス管３６の配置における相互の干渉を避けることができる。更に、主流路１４１と上流路１４３及び下流路１４４は直交し、且つ主流路１４１を挟んで上流路１４３の反対側に下流路１４４を配置するので、基体１３０内で各流路の配置間隔を狭めても、構成要素の組み付けにおける相互の干渉を避けることができ、基体１３０の小型化を図ることができる。 The upper flow path 143 in which the opening portion of the right surface 134 functions as the upper fire supply port 153 and the lower flow path 144 in which the opening portion of the right surface 134 functions as the lower fire supply port 154 both penetrate the base 130 in the left-right direction. When the base 130 is molded with a mold, if the upper fire supply port 153 and the lower fire supply port 154 are formed by the core forming the upper flow path 143 and the lower flow path 144, the opening directions of each are changed to the right side in the left-right direction. It can be formed accurately toward the target. Further, since the gas governor 110 can be arranged along the front-rear direction in which the main flow path 141 extends, mutual interference in the arrangement of the upper heat gas pipe 35 and the lower heat gas pipe 36 can be avoided. Further, since the main flow path 141, the upper flow path 143, and the lower flow path 144 are orthogonal to each other, and the lower flow path 144 is arranged on the opposite side of the upper flow path 143 with the main flow path 141 in between, the arrangement interval of each flow path is set in the base 130. Even if it is narrowed, mutual interference in assembling the components can be avoided, and the size of the base 130 can be reduced.

なお、本発明は上記実施形態に限定されるものではなく、種々の変更が可能である。上流路１４３が延びる方向と下流路１４４が延びる方向とは、必ずしも同じ方向でなくてもよい。また、上流路１４３が延びる方向は、必ずしも左右方向でなくてもよく、同様に、下流路１４４が延びる方向は、必ずしも左右方向でなくてもよい。なお、上記いずれの場合においても、上流路１４３の延びる方向に沿って上火供給口１５３が形成され、上火ガス管３５の上流端部３５Ａが上流路１４３の延びる方向に沿って上火供給口１５３に挿入され、且つ下流端部３５Ｂが、上流路１４３の延びる方向に沿って上火スロート部３７に接続される構成であればよい。同様に、上記いずれの場合においても、下流路１４４の延びる方向に沿って下火供給口１５４が形成され、下火ガス管３６の上流端部３６Ａが下流路１４４の延びる方向に沿って下火供給口１５４に挿入され、且つ下流端部３６Ｂが、下流路１４４の延びる方向に沿って下火スロート部３８に接続される構成であればよい。 The present invention is not limited to the above embodiment, and various modifications can be made. The direction in which the upper flow path 143 extends and the direction in which the lower flow path 144 extends do not necessarily have to be the same direction. Further, the direction in which the upper flow path 143 extends does not necessarily have to be the left-right direction, and similarly, the direction in which the lower flow path 144 extends does not necessarily have to be the left-right direction. In any of the above cases, the upper fire supply port 153 is formed along the extending direction of the upper flow path 143, and the upstream end 35A of the upper heat gas pipe 35 supplies the upper fire along the extending direction of the upper flow path 143. The configuration may be such that it is inserted into the mouth 153 and the downstream end portion 35B is connected to the upper fire throat portion 37 along the extending direction of the upper flow path 143. Similarly, in any of the above cases, the lower heat supply port 154 is formed along the extending direction of the lower flow path 144, and the upstream end portion 36A of the lower heat gas pipe 36 is lowered along the extending direction of the lower flow path 144. The configuration may be such that it is inserted into the supply port 154 and the downstream end portion 36B is connected to the lower fire throat portion 38 along the extending direction of the lower flow path 144.
