図３を参照し、燃料供給装置５２について説明する。ガスコンロ１は、右バーナ４、グリルバーナ（上火バーナ３２、下火バーナ３３）、左バーナ５、奥バーナ６の夫々にガスを供給する４つの燃料供給装置５１〜５４を備える。そのうち、右バーナ４、左バーナ５、奥バーナ６にガスを供給する燃料供給装置５１、５３、５４は、操作つまみ１１、１３、１４の押し込み操作と回動操作に応じ、コンロバーナの点火と消火、及びコンロバーナに供給するガス量を調節する。グリルバーナにガスを供給する燃料供給装置５２は、燃料供給装置５１、５３、５４と同様に操作つまみ１２の押し込み操作に応じてグリルバーナの点火と消火を行うが、ガス量の調節は行わない。なお、ガス量の調節は、別体に設けたガバナ装置１００が行う。ガバナ装置１００は、操作つまみ１２の回転位置によって、ガバナ装置１００に設けた電磁弁１７１，１７２を夫々個別に駆動し、上火バーナ３２と下火バーナ３３の強火及び弱火の組合せを切り替えることができる。燃料供給装置５１、５２は、筐体２内でグリル庫３１の右側面３１Ａと、筐体２の右壁部２１内面との間に形成される隙間領域Ｇ１に配置される。燃料供給装置５１、５２は、筐体２内でグリル庫３１の左側面３１Ｂと、筐体２の左壁部２２内面との間に形成される隙間領域Ｇ２に配置される。以下では、グリルバーナにガスを供給する燃料供給装置５２について説明を行い、右バーナ４、左バーナ５、奥バーナ６にガスを供給する燃料供給装置５１、５３、５４については説明を省略する。 The fuel supply device 52 will be described with reference to FIG. The gas stove 1 includes four fuel supply devices 51 to 54 that supply gas to each of the right burner 4, the grill burner (upper fire burner 32, lower fire burner 33), the left burner 5, and the back burner 6. Among them, the fuel supply devices 51, 53, and 54 that supply gas to the right burner 4, the left burner 5, and the back burner 6 ignite the stove burner in response to the pushing operation and the rotating operation of the operation knobs 11, 13, and 14. Extinguish the fire and adjust the amount of gas supplied to the stove burner. Like the fuel supply devices 51, 53, and 54, the fuel supply device 52 that supplies gas to the grill burner ignites and extinguishes the grill burner according to the pushing operation of the operation knob 12, but does not adjust the amount of gas. The amount of gas is adjusted by the governor device 100 provided separately. The governor device 100 individually drives the solenoid valves 171 and 172 provided in the governor device 100 according to the rotation position of the operation knob 12, and can switch the combination of high heat and low heat of the upper heat burner 32 and the lower heat burner 33. it can. The fuel supply devices 51 and 52 are arranged in the gap region G1 formed in the housing 2 between the right side surface 31A of the grill storage 31 and the inner surface of the right wall portion 21 of the housing 2. The fuel supply devices 51 and 52 are arranged in the gap region G2 formed in the housing 2 between the left side surface 31B of the grill storage 31 and the inner surface of the left wall portion 22 of the housing 2.

燃料供給装置５２は、操作つまみ１２の押し込み操作に応じ、グリルバーナの点火と消火を行う。燃料供給装置５２は、操作つまみ１２の操作に応じて動作する合成樹脂製で円筒状の前側本体５２Ａと、内部のガス流路にメイン弁６１及び安全弁６２を備える金属製で円筒状の後側本体５２Ｂとを備える。前側本体５２Ａの内部には、操作つまみ１２の押し込み操作によって前後に移動するスライダ６３が設けられる。スライダ６３は、メイン弁６１を開閉させる。安全弁６２は、後側本体５２Ｂのガス流路を閉じる閉状態に弾性付勢された電磁操作式の弁である。後側本体５２Ｂの下部には、ガス供給管６６が接続される接続部６４が設けられ、この接続部６４を介し、ガス供給管６６から後側本体５２Ｂのガス流路に向けてガスが導入される。後側本体５２Ｂの上部には、ガス流路を流れたガスが流出する流出口６５が設けられる。なお、メイン弁６１及び安全弁６２は周知のものであるので、これらの詳細な動作の説明を省略する。 The fuel supply device 52 ignites and extinguishes the grill burner in response to the pushing operation of the operation knob 12. The fuel supply device 52 is made of synthetic resin and has a cylindrical front main body 52A that operates in response to the operation of the operation knob 12, and a metal cylindrical rear side having a main valve 61 and a safety valve 62 in the internal gas flow path. It has a main body 52B. Inside the front main body 52A, a slider 63 that moves back and forth by pushing the operation knob 12 is provided. The slider 63 opens and closes the main valve 61. The safety valve 62 is an electromagnetically operated valve that is elastically urged to close the gas flow path of the rear main body 52B. A connecting portion 64 to which the gas supply pipe 66 is connected is provided in the lower part of the rear main body 52B, and gas is introduced from the gas supply pipe 66 toward the gas flow path of the rear main body 52B via the connecting portion 64. Will be done. An outflow port 65 through which the gas flowing through the gas flow path flows out is provided on the upper portion of the rear main body 52B. Since the main valve 61 and the safety valve 62 are well known, detailed description of their operation will be omitted.

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.

ガス分配装置１２０は、基体１３０に、電磁弁１７１，１７２、ニードル弁１６１，１６２等を組み付けて形成される。基体１３０は、溶融した金属（例えばアルミニウム又はアルミニウム合金）を上下方向に分割される金型に圧入して成型した、いわゆるダイカストである。基体１３０の内部には、ガスが流れる複数の流路が形成されている。なお、図５において、基体１３０内を流通するガスの流れを太線（実線又は点線）で示し、ガスが流れる向きを矢印で示す。 The gas distribution device 120 is formed by assembling solenoid valves 171 and 172, needle valves 161, 162 and the like on the base 130. The substrate 130 is a so-called die cast formed by press-fitting a molten metal (for example, aluminum or an aluminum alloy) into a mold divided in the vertical direction. A plurality of flow paths through which gas flows are formed inside the substrate 130. In FIG. 5, the flow of gas flowing through the substrate 130 is indicated by a thick line (solid line or dotted line), and the direction of gas flow is indicated by an arrow.

主流路１４１は基体１３０の略中心部を前後方向に延びる。主流路１４１の前端部は、基体１３０の前方を向く前面１３１に開口する。基体１３０の前面１３１は、固定部１３７に形成される。固定部１３７は左右方向に長い板状を呈し、左右両端部に、ガスガバナ１１０とガス分配装置１２０とを締結する固定ネジ１１７のネジ穴が設けられる。主流路１４１の前端部は、ガスガバナ１１０の流出口１１６から送出されるガスをガス分配装置１２０内に導入する導入口１５１として機能する。導入口１５１は前面１３１において前方に突出し、且つその周囲が前面１３１において環状に凹部形成されている。ガスガバナ１１０とガス分配装置１２０の固定時、導入口１５１にはＯリング１１８が配設され、接続部分におけるガス漏れが防止される。 The main flow path 141 extends substantially in the center of the substrate 130 in the front-rear direction. The front end portion of the main flow path 141 opens to the front surface 131 facing the front of the substrate 130. The front surface 131 of the substrate 130 is formed on the fixing portion 137. The fixing portion 137 has a long plate shape in the left-right direction, and screw holes for fixing screws 117 for fastening the gas governor 110 and the gas distribution device 120 are provided at both left and right ends. The front end portion of the main flow path 141 functions as an introduction port 151 for introducing the gas sent from the outlet 116 of the gas governor 110 into the gas distribution device 120. The introduction port 151 projects forward on the front surface 131, and the periphery thereof is formed in an annular recess on the front surface 131. When the gas governor 110 and the gas distribution device 120 are fixed, an O-ring 118 is provided at the introduction port 151 to prevent gas leakage at the connection portion.

基体１３０の後部には、上下方向に延びる溝状の分配室１４２が設けられる。分配室１４２は、基体１３０の後方を向く後面１３２において上下方向に延びる長円形状に開口し、前方へ向けて凹む凹部状に形成される。分配室１４２内には電磁弁１７１，１７２の弁体１７３，１７４（後述）が配置される。主流路１４１の後端部は、分配室１４２の底部略中央に開口する。 At the rear of the substrate 130, a groove-shaped distribution chamber 142 extending in the vertical direction is provided. The distribution chamber 142 is formed in a concave shape that opens in an oval shape extending in the vertical direction on the rear surface 132 facing the rear of the substrate 130 and is recessed toward the front. Valve bodies 173 and 174 (described later) of solenoid valves 171 and 172 are arranged in the distribution chamber 142. The rear end of the main flow path 141 opens substantially in the center of the bottom of the distribution chamber 142.

上流路１４３は基体１３０内で主流路１４１の上方に形成され、左右方向に延びる。上流路１４３の右端部は、基体１３０の右方を向く右面１３４に開口し、開口部分が上火供給口１５３として機能する。上火供給口１５３は右面１３４において円形の凹部状に形成され、底部中央に、上流路１４３の主部分に連通する穴部が開口する。上火供給口１５３には、グリルバーナのうちの上火バーナ３２にガスを輸送する上火ガス管３５の上流端部３５Ａが挿入される。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（後述）は、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、基体１３０から抜け止めされる。上流路１４３の左端部は、基体１３０の左方を向く左面１３３に開口する。上流路１４３の左端部は、分配室１４２から上流路１４３に流入するガスの流量を調整するニードル弁１６１が組み付けられる上火調整部１５５として機能する。上火調整部１５５の内径は、ニードル弁１６１の外径に合わせ、上流路１４３の主部分よりも大きい。 The upper flow path 143 is formed in the substrate 130 above the main flow path 141 and extends in the left-right direction. The right end portion of the upper flow path 143 opens to the right surface 134 facing the right side of the base 130, and the opening portion functions as the upper fire supply port 153. The upper fire supply port 153 is formed in a circular concave shape on the right surface 134, and a hole communicating with the main portion of the upper flow path 143 is opened in the center of the bottom portion. An upstream end portion 35A of the upper fire gas pipe 35 for transporting gas to the upper fire burner 32 of the grill burners is inserted into the upper fire supply port 153. At the upstream end 35A of the upper fire gas pipe 35 and the upstream end 36A (described later) of the lower fire gas pipe 36, a holding metal fitting 139 for preventing disconnection is fitted to the right side 134 of the base 130, and the base is fixed with a fixing screw 140. By being fixed to 130, it is prevented from coming off from the substrate 130. The left end of the upper flow path 143 opens to the left surface 133 facing the left side of the substrate 130. The left end of the upper flow path 143 functions as an upper fire adjusting portion 155 to which the needle valve 161 for adjusting the flow rate of the gas flowing from the distribution chamber 142 into the upper flow path 143 is assembled. The inner diameter of the upper fire adjusting portion 155 matches the outer diameter of the needle valve 161 and is larger than the main portion of the upper flow path 143.

上火開閉路１４５は基体１３０内で前後方向に延び、分配室１４２と上流路１４３の主部分とを接続する。上火開閉路１４５の後端部は、分配室１４２の底部において、主流路１４１の開口よりも上方の位置に開口する。分配室１４２内の上火開閉路１４５の開口は、電磁弁１７１の弁体１７３によって開閉される。上火バイパス路１４７は基体１３０内で前後方向に延び、分配室１４２と上火調整部１５５とを接続する。上火バイパス路１４７の後端部は、分配室１４２の底部において、上火開閉路１４５の開口よりも左方の位置に開口する。分配室１４２内の上火バイパス路１４７の開口は、常時開いた状態である。 The upper fire switching path 145 extends in the front-rear direction in the substrate 130 and connects the distribution chamber 142 and the main portion of the upper flow path 143. The rear end of the upper fire switching path 145 opens at the bottom of the distribution chamber 142 at a position above the opening of the main flow path 141. The opening of the upper fire switching path 145 in the distribution chamber 142 is opened and closed by the valve body 173 of the solenoid valve 171. The upper fire bypass path 147 extends in the front-rear direction in the base 130 and connects the distribution chamber 142 and the upper fire adjustment unit 155. The rear end of the upper fire bypass path 147 opens at the bottom of the distribution chamber 142 at a position to the left of the opening of the upper fire switching path 145. The opening of the upper fire bypass path 147 in the distribution chamber 142 is always open.

上火調整部１５５には、基体１３０の左面１３３側よりニードル弁１６１が挿入される。ニードル弁１６１は左右方向に長く、側面の横穴と右面の縦穴が内部で連通する。ニードル弁１６１の横穴は上火バイパス路１４７の前端部の開口に向き合って配置され、縦穴は上流路１４３内に開口する。分配室１４２から上火バイパス路１４７を通り上火調整部１５５内に流れるガスは、横穴と縦穴を通り、上流路１４３に流通する。ニードル弁１６１は、上火バイパス路１４７から上流路１４３に流通するガスを遮断しないが、小径に形成された縦穴によってガスの流量を制限する。ニードル弁１６１は、基体１３０の左面１３３に締結される押えネジ１６３によって上火調整部１５５内に保持される。また、ニードル弁１６１には２つのＯリングが設けられており、上火調整部１５５においてニードル弁１６１を介さないガスの流通が防止される。 The needle valve 161 is inserted into the top heat adjusting portion 155 from the left side 133 side of the base 130. The needle valve 161 is long in the left-right direction, and the horizontal hole on the side surface and the vertical hole on the right side communicate internally. The horizontal hole of the needle valve 161 is arranged so as to face the opening at the front end of the upper fire bypass path 147, and the vertical hole opens in the upper flow path 143. The gas flowing from the distribution chamber 142 through the upper heat bypass path 147 and into the upper fire adjusting unit 155 passes through the horizontal hole and the vertical hole and flows to the upper flow path 143. The needle valve 161 does not block the gas flowing from the upper fire bypass path 147 to the upper flow path 143, but limits the gas flow rate by a vertical hole formed in a small diameter. The needle valve 161 is held in the top heat adjusting portion 155 by a pressing screw 163 fastened to the left surface 133 of the base 130. Further, the needle valve 161 is provided with two O-rings, and the upper fire adjusting unit 155 prevents the flow of gas without passing through the needle valve 161.

下流路１４４は基体１３０内で主流路１４１の下方に形成され、左右方向に延びる。下流路１４４の右端部は、基体１３０の右面１３４に開口し、開口部分が下火供給口１５４として機能する。下火供給口１５４は、上火供給口１５３の下方に設けられる。下火供給口１５４は右面１３４において円形の凹部状に形成され、底部中央に、下火供給口１５４の主部分に連通する穴部が開口する。下火供給口１５４には、グリルバーナのうちの下火バーナ３３にガスを輸送する下火ガス管３６の上流端部３６Ａが挿入される。下流路１４４の左端部は、基体１３０の左面１３３に開口する。下流路１４４の左端部は、分配室１４２から下流路１４４に流入するガスの流量を調整するニードル弁１６２が組み付けられる下火調整部１５６として機能する。下火調整部１５６の内径は、ニードル弁１６２の外径に合わせ、下流路１４４の主部分よりも大きい。 The lower flow path 144 is formed in the substrate 130 below the main flow path 141 and extends in the left-right direction. The right end portion of the lower flow path 144 opens to the right surface 134 of the base 130, and the opening portion functions as the lower fire supply port 154. The lower fire supply port 154 is provided below the upper fire supply port 153. The lower fire supply port 154 is formed in a circular concave shape on the right surface 134, and a hole communicating with the main portion of the lower fire supply port 154 opens in the center of the bottom portion. An upstream end portion 36A of the lower heat gas pipe 36 for transporting gas to the lower heat burner 33 of the grill burners is inserted into the lower heat supply port 154. The left end of the lower flow path 144 opens to the left surface 133 of the substrate 130. The left end of the lower flow path 144 functions as a lower heat adjusting portion 156 to which a needle valve 162 for adjusting the flow rate of the gas flowing from the distribution chamber 142 into the lower flow path 144 is assembled. The inner diameter of the lower heat adjusting portion 156 matches the outer diameter of the needle valve 162 and is larger than the main portion of the lower flow path 144.

このように、上流路１４３と下流路１４４は、基体１３０内において主流路１４１に直交し、且つ主流路１４１を挟んで上側と下側に形成される。上流路１４３と下流路１４４は、夫々、上火ガス管３５と下火ガス管３６が接続される上火供給口１５３と下火供給口１５４を有する。上火供給口１５３と下火供給口１５４は、基体１３０の右面１３４において上下方向に並んで配置される。上火ガス管３５と下火ガス管３６の夫々を基体１３０に接続する上で、右面１３４には相互干渉を避けるための接続しろが必要となる。上流路１４３と下流路１４４の間に主流路１４１を配置する構成にしたことで、基体１３０は、上流路１４３と下流路１４４との間に設けられた間隙を、上火供給口１５３と下火供給口１５４の周囲に設ける接続しろに利用することができる。 As described above, the upper flow path 143 and the lower flow path 144 are formed in the substrate 130 at right angles to the main flow path 141 and on the upper side and the lower side with the main flow path 141 interposed therebetween. The upper flow path 143 and the lower flow path 144 each have an upper fire supply port 153 and a lower fire supply port 154 to which the upper fire gas pipe 35 and the lower fire gas pipe 36 are connected. The upper fire supply port 153 and the lower fire supply port 154 are arranged side by side in the vertical direction on the right side 134 of the base 130. In connecting each of the upper heat gas pipe 35 and the lower heat gas pipe 36 to the substrate 130, a connection margin is required on the right side 134 to avoid mutual interference. By arranging the main flow path 141 between the upper flow path 143 and the lower flow path 144, the substrate 130 fills the gap provided between the upper flow path 143 and the lower flow path 144 with the upper fire supply port 153 and lower. It can be used as a connection margin provided around the fire supply port 154.

下火開閉路１４６は基体１３０内で前後方向に延び、分配室１４２と下流路１４４の主部分とを接続する。下火開閉路１４６の後端部は、分配室１４２の底部において、主流路１４１の開口よりも下方の位置に開口する。分配室１４２内の下火開閉路１４６の開口は、電磁弁１７２の弁体１７４によって開閉される。下火バイパス路１４８は基体１３０内で前後方向に延び、分配室１４２と下火調整部１５６とを接続する。下火バイパス路１４８の後端部は、分配室１４２の底部において、下火開閉路１４６の開口よりも左方の位置に開口する。分配室１４２内の下火バイパス路１４８の開口は、常時開いた状態である。 The lower fire switching path 146 extends in the front-rear direction in the base 130 and connects the distribution chamber 142 and the main portion of the lower flow path 144. The rear end of the lower fire switching path 146 opens at the bottom of the distribution chamber 142 at a position below the opening of the main flow path 141. The opening of the lower fire switching path 146 in the distribution chamber 142 is opened and closed by the valve body 174 of the solenoid valve 172. The lower heat bypass path 148 extends in the front-rear direction in the base 130 and connects the distribution chamber 142 and the lower heat adjustment unit 156. The rear end of the lower fire bypass path 148 opens at the bottom of the distribution chamber 142 at a position to the left of the opening of the lower fire switching path 146. The opening of the lower fire bypass path 148 in the distribution chamber 142 is always open.

下火調整部１５６には、基体１３０の左面１３３側よりニードル弁１６２が挿入される。ニードル弁１６２は左右方向に長く、側面の横穴と右面の縦穴が内部で連通する。ニードル弁１６２の横穴は下火バイパス路１４８の前端部の開口に向き合って配置され、縦穴は下流路１４４内に開口する。分配室１４２から下火バイパス路１４８を通り下火調整部１５６内に流れるガスは、横穴と縦穴を通り、下流路１４４に流通する。ニードル弁１６２は、下火バイパス路１４８から下流路１４４に流通するガスを遮断しないが、小径に形成された縦穴によってガスの流量を制限する。ニードル弁１６２は、基体１３０の左面１３３に締結される押えネジ１６４によって下火調整部１５６内に保持される。また、ニードル弁１６２には２つのＯリングが設けられており、下火調整部１５６においてニードル弁１６２を介さないガスの流通が防止される。 The needle valve 162 is inserted into the lower heat adjusting portion 156 from the left side 133 side of the base 130. The needle valve 162 is long in the left-right direction, and the horizontal hole on the side surface and the vertical hole on the right side communicate internally. The horizontal hole of the needle valve 162 is arranged so as to face the opening at the front end of the lower fire bypass path 148, and the vertical hole opens in the lower flow path 144. The gas flowing from the distribution chamber 142 through the lower heat bypass path 148 and into the lower heat adjustment unit 156 passes through the horizontal hole and the vertical hole and flows to the lower flow path 144. The needle valve 162 does not shut off the gas flowing from the lower heat bypass path 148 to the lower flow path 144, but limits the gas flow rate by a vertical hole formed in a small diameter. The needle valve 162 is held in the lower heat adjusting portion 156 by a pressing screw 164 fastened to the left surface 133 of the base 130. Further, the needle valve 162 is provided with two O-rings, and the lower heat adjusting unit 156 prevents the flow of gas without passing through the needle valve 162.

The upper end of the detection path 149 opens at the upper surface 135 facing upward of the substrate 130, and the periphery of the opening portion protrudes upward in a tubular shape. The upper end of the detection path 149 is used during manufacturing and maintenance of the gas stove 1 and functions as a detection port 157 to which a detector (not shown) for detecting gas pressure can be attached, and is usually sealed with a gasket (not shown). It is sealed with a set screw 138. In addition, each flow path does not open on the lower surface 136 facing downward of the substrate 130.

電磁弁１７１、１７２は固定金具１７５に一体に保持される。固定金具１７５は平板状を呈し、背面側に固定する電磁弁１７１，１７２の弁体１７３，１７４を、２つの貫通穴を介して夫々前面に露出する。貫通穴はＯリング（図示略）等により封止される。固定金具１７５は基体１３０の後面１３２に対向して配置され、弁体１７３，１７４を分配室１４２内に配置した状態で、４本の固定ネジ１７７により基体１３０に固定される。基体１３０の後面１３２には、長円形を呈する円環状のパッキン１７６を配置するための配置部１５２が形成されている。配置部１５２は、後面１３２において、分配室１４２の開口部分の周囲を一周する長円形の溝状に形成される。分配室１４２の内面は、基体１３０を後方から見たときに、後面１３２の上端及び下端に近い位置に延びて形成される。故に配置部１５２の上側の円弧部分である上端部１５２Ａ及び下側の円弧部分である下端部１５２Ｂは、基体１３０の上面１３５及び下面１３６の夫々よりも、上方及び下方に突出する。言い換えると、基体１３０の上面１３５は、配置部１５２の上側の上端部１５２Ａよりも下方に位置し、基体１３０の下面１３６は、配置部１５２の下側の下端部１５２Ｂよりも上方に位置する。固定金具１７５は、配置部１５２に配置したパッキン１７６を基体１３０の後面１３２との間に挟むことで、分配室１４２の開口部分を密閉状態に蓋する。電磁弁１７１、１７２の弁体１７３，１７４は夫々、分配室１４２内で上火開閉路１４５、下火開閉路１４６の開口の後方に配置される。電磁弁１７１、１７２が駆動すると、弁体１７３，１７４は夫々、上火開閉路１４５、下火開閉路１４６の開口を閉鎖し、ガスの流路を夫々、上火バイパス路１４７、下火バイパス路１４８を介した流路に制限する。 The solenoid valves 171 and 172 are integrally held by the fixing bracket 175. The fixing bracket 175 has a flat plate shape, and the valve bodies 173 and 174 of the solenoid valves 171 and 172 fixed to the back surface side are exposed to the front surface through the two through holes, respectively. The through hole is sealed with an O-ring (not shown) or the like. The fixing bracket 175 is arranged so as to face the rear surface 132 of the base 130, and is fixed to the base 130 by four fixing screws 177 in a state where the valve bodies 173 and 174 are arranged in the distribution chamber 142. An arrangement portion 152 for arranging an annular packing 176 having an oval shape is formed on the rear surface 132 of the base 130. The arrangement portion 152 is formed on the rear surface 132 in the shape of an oval groove that goes around the opening portion of the distribution chamber 142. The inner surface of the distribution chamber 142 is formed so as to extend to positions close to the upper and lower ends of the rear surface 132 when the substrate 130 is viewed from the rear. Therefore, the upper end portion 152A, which is the upper arc portion of the arrangement portion 152, and the lower end portion 152B, which is the lower arc portion, project upward and downward from the upper surface 135 and the lower surface 136 of the base 130, respectively. In other words, the upper surface 135 of the base 130 is located below the upper upper end 152A of the placement portion 152, and the lower surface 136 of the base 130 is located above the lower end 152B below the placement portion 152. The fixing bracket 175 covers the opening portion of the distribution chamber 142 in a sealed state by sandwiching the packing 176 arranged in the arrangement portion 152 between the packing 176 and the rear surface 132 of the base 130. The valve bodies 173 and 174 of the solenoid valves 171 and 172 are arranged in the distribution chamber 142 behind the openings of the upper fire switching path 145 and the lower fire switching path 146, respectively. When the solenoid valves 171 and 172 are driven, the valve bodies 173 and 174 close the openings of the upper fire switching path 145 and the lower fire switching path 146, respectively, and pass the gas flow path through the upper fire bypass path 147 and the lower fire bypass, respectively. It is limited to the flow path via the road 148.

前述したように、本実施形態のガス分配装置１２０の基体１３０は、金型により成型されるダイカストである。主流路１４１は基体１３０の前面１３１にて開口し、導入口１５１を形成する。分配室１４２は基体１３０の後面１３２にて上下方向に延びて開口し、主流路１４１と接続する。この構成により、主流路１４１と分配室１４２は、基体１３０の前面１３１から後面１３２にかけて前後方向に貫通する直線的な流路として形成することができる。また、上流路１４３は、基体１３０の左面１３３に開口して上火調整部１５５を形成すると共に、基体１３０の右面１３４においても開口して上火供給口１５３を形成する。同様に、下流路１４４は、基体１３０の左面１３３に開口して下火調整部１５６を形成すると共に、基体１３０の右面１３４においても開口して下火供給口１５４を形成する。この構成により、上流路１４３と下流路１４４は、基体１３０の左面１３３から右面１３４にかけて左右方向に貫通する直線的な流路として形成することができる。主流路１４１、分配室１４２、上流路１４３、下流路１４４が上記のように基体１３０を前後方向及び左右方向に貫通して形成される関係にあるからこそ、基体１３０は、前面１３１、後面１３２、左面１３３、右面１３４の夫々に対し、ガスガバナ１１０との接続口、電磁弁１７１，１７２の配置部、ニードル弁１６１，１６２の配置部、上火ガス管３５、下火ガス管３６との接続口などの機能部分を効率よく配置でき、小型化を図ることができる。更に、上火開閉路１４５及び下火開閉路１４６と、上火バイパス路１４７及び下火バイパス路１４８は夫々、分配室１４２から前後方向に延び、上流路１４３及び下流路１４４に連結する構成である。故に基体１３０は、金型による成型において、各流路や機能部分をピンや中子等を用いて容易に形成することができ、更に型抜きも容易に行うことができる。 As described above, the base 130 of the gas distribution device 120 of the present embodiment is a die cast molded by a mold. The main flow path 141 opens at the front surface 131 of the substrate 130 to form the introduction port 151. The distribution chamber 142 extends in the vertical direction at the rear surface 132 of the substrate 130 and opens to connect with the main flow path 141. With this configuration, the main flow path 141 and the distribution chamber 142 can be formed as a linear flow path penetrating in the front-rear direction from the front surface 131 to the rear surface 132 of the substrate 130. Further, the upper flow path 143 opens to the left surface 133 of the base 130 to form the upper fire adjusting portion 155, and also opens to the right surface 134 of the base 130 to form the upper fire supply port 153. Similarly, the lower flow path 144 opens to the left surface 133 of the base 130 to form the lower fire adjusting portion 156, and also opens to the right side 134 of the base 130 to form the lower fire supply port 154. With this configuration, the upper flow path 143 and the lower flow path 144 can be formed as a linear flow path penetrating in the left-right direction from the left surface 133 to the right surface 134 of the substrate 130. The base 130 has a front surface 131 and a rear surface 132 because the main flow path 141, the distribution chamber 142, the upper flow path 143, and the lower flow path 144 are formed so as to penetrate the base 130 in the front-rear direction and the left-right direction as described above. , The connection port with the gas governor 110, the arrangement part of the solenoid valves 171 and 172, the arrangement part of the needle valves 161 and 162, the connection with the upper heat gas pipe 35 and the lower heat gas pipe 36 with respect to each of the left side 133 and the right side 134. Functional parts such as the mouth can be arranged efficiently, and miniaturization can be achieved. Further, the upper fire switching path 145 and the lower fire switching path 146, and the upper fire bypass path 147 and the lower fire bypass path 148 each extend in the front-rear direction from the distribution chamber 142 and are connected to the upper flow path 143 and the lower flow path 144. is there. Therefore, in the molding with a mold, each flow path and functional portion of the substrate 130 can be easily formed by using a pin, a core, or the like, and further, die cutting can be easily performed.

以上説明したように、ガス分配装置１２０の基体１３０は、異なる方向を向く各面に、ガスガバナ１１０に接続する導入口１５１、上火ガス管３５及び下火ガス管３６が接続する上火供給口１５３及び下火供給口１５４、ニードル弁１６１，１６２が取り付けられる上火調整部１５５及び下火調整部１５６、ガスを分配する分配室１４２が夫々設けられる。ガバナ装置１００に必要な構成要素をガス分配装置１２０に集約しつつも夫々を基体１３０の各面に配置したことで、ガス分配装置１２０の小型化を図ることができる。 As described above, the base 130 of the gas distribution device 120 has an introduction port 151 connected to the gas governor 110, an upper fire gas pipe 35 and a lower fire gas pipe 36 connected to each surface facing different directions. 153, a lower heat supply port 154, an upper heat adjusting unit 155 and a lower heat adjusting unit 156 to which needle valves 161, 162 are attached, and a distribution chamber 142 for distributing gas are provided, respectively. By consolidating the components required for the governor device 100 into the gas distributor 120 and arranging each of them on each surface of the substrate 130, the gas distributor 120 can be miniaturized.

基体１３０を直方体形状にすることで、より小さく形成することができる。そして、各流路が直交し、更に主流路１４１と上流路１４３及び下流路１４４は貫通するので、基体１３０を金型で成型する場合に各流路を形成するためのピンや中子等を抜きやすくでき、成型しやすい。 By forming the substrate 130 into a rectangular parallelepiped shape, it can be made smaller. Then, since each flow path is orthogonal to each other and further penetrates the main flow path 141, the upper flow path 143, and the lower flow path 144, pins, cores, and the like for forming each flow path are provided when the substrate 130 is molded with a mold. Easy to pull out and easy to mold.

上流路１４３及び下流路１４４の上火供給口１５３及び下火供給口１５４の周囲には、上火ガス管３５及び下火ガス管３６を夫々接続する上での相互干渉を避けるための接続しろが必要となる。よって、上流路１４３及び下流路１４４を隣り合わせて配置する場合、接続しろのための間隙を離して配置することになる。そこで、上流路１４３及び下流路１４４の間に主流路１４１を配置する構成にすれば、接続しろのための間隙が主流路１４１の配置にも使用できるので、基体１３０の小型化を図ることができる。 Connect around the upper fire supply port 153 and the lower fire supply port 154 of the upper flow path 143 and the lower flow path 144 to avoid mutual interference when connecting the upper fire gas pipe 35 and the lower fire gas pipe 36, respectively. Is required. Therefore, when the upper flow path 143 and the lower flow path 144 are arranged side by side, they are arranged with a gap for connection margin. Therefore, if the main flow path 141 is arranged between the upper flow path 143 and the lower flow path 144, the gap for the connection margin can be used for the arrangement of the main flow path 141, so that the size of the substrate 130 can be reduced. it can.

分配室１４２は上下方向に延びるが、配置部１５２は、分配室１４２の開口部分の周囲に設けたので、分配室１４２よりも上下方向に大きい。そして、配置部１５２の上端部１５２Ａは、上面１３５よりも上側に突出して設けられ、配置部１５２の下端部１５２Ｂは、下面１３６よりも下側に突出して設けられる。言い換えると、上面１３５と下面１３６は、上下方向において、配置部１５２の上端部１５２Ａと下端部１５２Ｂよりも、夫々分配室１４２側に位置する。すなわち上面１３５は上流路１４３に対し、より近い位置に位置することができ、下面１３６は下流路１４４に対し、より近い位置に位置することができる。よって、基体１３０の構成材料の使用量を減らすことができるので、ガス分配装置１２０の小型化を図ることができる。 The distribution chamber 142 extends in the vertical direction, but since the arrangement portion 152 is provided around the opening portion of the distribution chamber 142, it is larger in the vertical direction than the distribution chamber 142. The upper end portion 152A of the arrangement portion 152 is provided so as to project upward from the upper surface 135, and the lower end portion 152B of the arrangement portion 152 is provided so as to project below the lower surface 136. In other words, the upper surface 135 and the lower surface 136 are located closer to the distribution chamber 142 than the upper end 152A and the lower end 152B of the arrangement portion 152 in the vertical direction, respectively. That is, the upper surface 135 can be located closer to the upper flow path 143, and the lower surface 136 can be located closer to the lower flow path 144. Therefore, since the amount of the constituent material used for the substrate 130 can be reduced, the gas distribution device 120 can be downsized.

ガス分配装置１２０の基体１３０には、更に、上面１３５に、検出器を取付可能な検出口１５７が設けられる。ガバナ装置１００に必要な構成要素をガス分配装置１２０に集約しつつも夫々を基体１３０の各面に配置したことで、ガス分配装置１２０の小型化を図ることができる。 The base 130 of the gas distributor 120 is further provided with a detection port 157 on the upper surface 135 to which a detector can be attached. By consolidating the components required for the governor device 100 into the gas distributor 120 and arranging each of them on each surface of the substrate 130, the gas distributor 120 can be miniaturized.

ガス分配装置１２０の小型化を図ることにより、ガスコンロ１は、筐体２内における配置レイアウトの自由度を確保することができる。 By downsizing the gas distribution device 120, the gas stove 1 can secure the degree of freedom in the arrangement layout in the housing 2.

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。主流路１４１は、上下方向において、上流路１４３と下流路１４４の間に設けたが、上流路１４３よりも上側あるいは下流路１４４よりも下側に設けてもよい。 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. The main flow path 141 is provided between the upper flow path 143 and the lower flow path 144 in the vertical direction, but may be provided above the upper flow path 143 or below the lower flow path 144.

検出口１５７は、必ずしも上面１３５に設けなくてもよい。例えば図６に示す基体２３０のように、検出口２５７を基体２３０の後面１３２に設けてもよい。検出路２４９は基体２３０内で前後方向に延び、前端部が上流路１４３の主部分に接続する。検出路２４９の後端部は、基体１３０の後面１３２に開口し、開口部分の周囲が後方へ向けて筒状に突出する検出口２５７として機能してもよい。このような構成としても、ガバナ装置１００に必要な構成要素をガス分配装置１２０に集約しつつも夫々を基体２３０の各面に配置することで、ガス分配装置１２０の小型化を図ることができる。また、上下方向に沿う流路がなく、基体２３０を金型で成型する場合に各流路を形成するためのピンや中子等の向きを前後方向及び左右方向に限定できるので、ピンや中子等をより抜きやすく、成型しやすい。 The detection port 157 does not necessarily have to be provided on the upper surface 135. For example, as in the substrate 230 shown in FIG. 6, the detection port 257 may be provided on the rear surface 132 of the substrate 230. The detection path 249 extends in the front-rear direction in the substrate 230, and the front end portion connects to the main portion of the upper flow path 143. The rear end portion of the detection path 249 may function as a detection port 257 that opens to the rear surface 132 of the substrate 130 and the periphery of the opening portion projects rearward in a tubular shape. Even with such a configuration, the gas distributor 120 can be downsized by arranging the components required for the governor device 100 on each surface of the substrate 230 while consolidating them on the gas distributor 120. .. Further, since there is no flow path along the vertical direction and the directions of the pins and cores for forming each flow path can be limited to the front-rear direction and the left-right direction when the substrate 230 is molded with a mold, the pins and the middle It is easier to pull out children, etc., and it is easier to mold.
