Description

本発明はガスコンロに関する。 The present invention relates to gas stoves.

ガスコンロの上部には複数のコンロバーナが配置され、各コンロバーナへのガスの供給と遮断を行う燃料供給装置は、ガスコンロの筐体内の前部に配置される。また、ガスコンロにはグリルバーナを備えたグリル庫が設けられ、燃料供給装置からグリルバーナへガスを供給するガス管にはガバナ装置が取り付けられる。ガバナ装置は、調圧ネジ付きの蓋体と固定部との間にダイヤフラムを挟み、固定ネジで固定するガバナを備える（例えば特許文献１参照）。ダイヤフラムは、燃料供給装置から供給されるガスの圧力に応じて変形し、ダイヤフラムに連結する弁体を移動することで、ガバナを通過するガスの流量を調節する。これにより、ガバナ装置は圧力が安定したガスをグリルバーナに供給する。 A plurality of stove burners are arranged above the gas stove, and a fuel supply device for supplying and shutting off gas to each stove burner is arranged in the front part of the housing of the gas stove. Further, the gas stove is provided with a grill storage having a grill burner, and a governor device is attached to a gas pipe that supplies gas from the fuel supply device to the grill burner. A governor device includes a governor that sandwiches a diaphragm between a lid with a pressure adjusting screw and a fixing portion and fixes the diaphragm with a fixing screw (see, for example, Patent Document 1). The diaphragm deforms according to the pressure of the gas supplied from the fuel supply device, and moves a valve body connected to the diaphragm to adjust the flow rate of gas passing through the governor. As a result, the governor device supplies gas with a stable pressure to the grill burner.

調圧部１２０は、ガスガバナ１３０と延伸部１５０を備える。ガスの調圧は、ガスガバナ１３０によって行われる。ガスガバナ１３０は、蓋体１３２、弁座部１４０、ダイヤフラム１３３、弁体１３６、弁座１３７、調圧バネ１３４、調整ネジ１３５を備える。蓋体１３２は、ダイカストにより成型された金属製の部品である。蓋体１３２は、左右に長い略六角形状の板状で角部がＲ面取りされた基部１３１の中央部分が斜め上方へ向けて円形の台状に突出し、更にその中央部分が斜め上方へ向けて略釣鐘状に突出した形状を呈する。 The pressure regulating section 120 includes a gas governor 130 and an extension section 150 . Gas pressure regulation is performed by the gas governor 130 . The gas governor 130 includes a lid body 132 , a valve seat portion 140 , a diaphragm 133 , a valve body 136 , a valve seat 137 , a pressure regulating spring 134 and an adjusting screw 135 . The lid body 132 is a metal component molded by die casting. The cover body 132 has a substantially hexagonal plate shape elongated in the left and right direction. The central portion of a base portion 131 with R-chamfered corners protrudes obliquely upward in the shape of a circular pedestal. It has a shape protruding in a substantially bell shape.

弁座部１４０は、延伸部１５０と一体にダイカストにより成型された金属製の部品である。弁座部１４０は蓋体１３２の基部１３１を受け、燃料供給装置５２及び延伸部１５０を介して分配部１１０に連結する。弁座部１４０には、基部１３１との合わせ面を形成する受部１４１の中央部分が斜め下方へ向けて円形に凹む形状の凹部１４２が形成される。燃料供給装置５２から供給されるガスがガスガバナ１３０内に流入する流入口１４３は、凹部１４２の中央部分に開口し、凹部１４２の斜め下方へ向けて延びる。燃料供給装置５２の流出口６５に連結し、燃料供給装置５２から供給されるガスをガスガバナ１３０に導入する導入口１４４は、弁座部１４０の底部に開口する。導入口１４４は上下方向に延び、凹部１４２の斜め下方において流入口１４３と接続する。 The valve seat portion 140 is a metal component integrally formed with the extending portion 150 by die casting. The valve seat portion 140 receives the base portion 131 of the lid body 132 and is connected to the distribution portion 110 via the fuel supply device 52 and the extension portion 150 . The valve seat portion 140 is formed with a recess 142 in which the central portion of the receiving portion 141 forming a mating surface with the base portion 131 is recessed obliquely downward in a circular shape. An inflow port 143 through which gas supplied from the fuel supply device 52 flows into the gas governor 130 opens in the central portion of the recess 142 and extends obliquely downward from the recess 142 . An introduction port 144 , which is connected to the outflow port 65 of the fuel supply device 52 and introduces the gas supplied from the fuel supply device 52 into the gas governor 130 , opens at the bottom of the valve seat portion 140 . The inlet 144 extends vertically and connects with the inlet 143 obliquely below the recess 142 .

また、弁座部１４０には、流入口１４３と導入口１４４との接続部分から斜め下方へ向けて突出する突出部１４５が形成される。突出部１４５は、流入口１４３が延びる斜め方向に対して直交し、斜め下方を向く平面部１４６を有する。 Further, the valve seat portion 140 is formed with a protruding portion 145 that protrudes obliquely downward from the connecting portion between the inflow port 143 and the introduction port 144 . The protruding portion 145 has a flat portion 146 that is perpendicular to the oblique direction in which the inlet 143 extends and faces obliquely downward.

ガスガバナ１３０で調圧したガスを排出する排出口１４７は、流入口１４３よりも上側において凹部１４２内に開口し、凹部１４２の斜め下方へ向けて延びる。排出口１４７は流入口１４３に並行して延び、延伸部１５０のガス流路１５３に接続する。延伸部１５０は弁座部１４０から後方へ延び、後端部に、調圧部１２０を分配部１１０に固定する固定部１５１が形成される。ガス流路１５３は延伸部１５０内を前後方向に延び、固定部１５１の後面において開口する。固定部１５１は左右方向に長い板状を呈し、左右両端部に、固定ネジ１５２が挿通される挿通穴を有する。延伸部１５０が設けられることによって、ガスガバナ１３０は、筐体２内で、分配部１１０の配置位置に対してより前方の位置に配置される。 A discharge port 147 for discharging the gas pressure-regulated by the gas governor 130 opens into the recess 142 above the inlet 143 and extends obliquely downward from the recess 142 . The outlet 147 extends parallel to the inlet 143 and connects to the gas flow path 153 of the extension 150 . The extending portion 150 extends rearward from the valve seat portion 140 and has a fixing portion 151 formed at its rear end for fixing the pressure regulating portion 120 to the distributing portion 110 . The gas flow path 153 extends in the longitudinal direction inside the extended portion 150 and opens at the rear surface of the fixed portion 151 . The fixing portion 151 has a plate shape elongated in the left-right direction, and has insertion holes through which fixing screws 152 are inserted at both left and right ends. By providing the extended portion 150 , the gas governor 130 is arranged at a position forward of the distributing portion 110 in the housing 2 .

ダイヤフラム１３３は可撓性を有する円形の膜体である。ダイヤフラム１３３は、その周縁部が、蓋体１３２の基部１３１と弁座部１４０の受部１４１との間に挟み込まれた状態で、基部１３１と受部１４１とが固定ネジ１３８によって締結されることで、ガスガバナ１３０の内部に固定される。ダイヤフラム１３３は、蓋体１３２の内部に設けられた調圧バネ１３４によって、弁座部１４０に向けて付勢される。調圧バネ１３４の付勢力は、調整ネジ１３５の締め付け度合によって調整される。調圧バネ１３４の付勢力の調整は、主にガスコンロ１の設置時に行われる。 The diaphragm 133 is a flexible circular membrane. The base 131 and the receiving portion 141 of the valve seat portion 140 are fastened together with a fixing screw 138 while the peripheral portion of the diaphragm 133 is sandwiched between the base portion 131 of the lid 132 and the receiving portion 141 of the valve seat portion 140 . , and is fixed inside the gas governor 130 . The diaphragm 133 is biased toward the valve seat portion 140 by a pressure regulating spring 134 provided inside the lid 132 . The biasing force of the pressure adjusting spring 134 is adjusted by the tightening degree of the adjusting screw 135 . Adjustment of the biasing force of the pressure adjusting spring 134 is mainly performed when the gas stove 1 is installed.

弁体１３６は流入口１４３を開閉する弁であり、流入口１４３が延びる斜め方向に延びる軸部と、軸部の下端部に形成される半球状の弁部を有する。軸部の上部は、ダイヤフラム１３３の中央部に連結する。弁部は、流入口１４３の内部に配置される。弁座１３７は金属製で円環状を呈し、流入口１４３内に圧入される。弁体１３６の弁部は、流入口１４３内で弁座１３７の下方に配置され、軸部は弁座１３７の環内を挿通される。弁座１３７は、弁体１３６の弁部を流入口１４３内で受け、弁部との間にガスが流通する間隙を形成する。すなわち弁座１３７と弁部が接触するとガスは流通せず、弁座１３７と弁部の間隙が広がるにつれ、ガスの流量が多くなる。弁座部１４０の凹部１４２は、ダイヤフラム１３３によって蓋体１３２の内部と隔離される。凹部１４２とダイヤフラム１３３によって仕切られる部分には、ガス流路１５３から流入して排出口１４７から排出されるガスが流通する圧力室１４９が形成される。蓋体１３２とダイヤフラム１３３によって形成され、圧力室１４９に対しダイヤフラム１３３によって仕切られる部分には、ダイヤフラム１３３に調圧バネ１３４の付勢力が付与される背圧室１３９が形成される。 The valve element 136 is a valve that opens and closes the inflow port 143, and has a shaft extending obliquely to the inflow port 143 and a hemispherical valve formed at the lower end of the shaft. The upper portion of the shaft portion is connected to the central portion of the diaphragm 133 . The valve portion is arranged inside the inlet 143 . The valve seat 137 is made of metal, has an annular shape, and is press-fitted into the inlet 143 . The valve portion of the valve body 136 is arranged below the valve seat 137 within the inlet 143 , and the shaft portion is inserted through the ring of the valve seat 137 . The valve seat 137 receives the valve portion of the valve body 136 within the inflow port 143 and forms a gap through which gas flows between the valve seat 137 and the valve portion. That is, when the valve seat 137 and the valve portion come into contact with each other, the gas does not flow. The recessed portion 142 of the valve seat portion 140 is isolated from the inside of the lid 132 by the diaphragm 133 . A portion partitioned by the recess 142 and the diaphragm 133 forms a pressure chamber 149 through which gas flows from the gas flow path 153 and is discharged from the discharge port 147 . A back pressure chamber 139 is formed in a portion defined by the lid 132 and the diaphragm 133 and partitioned by the diaphragm 133 with respect to the pressure chamber 149 .

分配部１１０は、調圧部１２０の後部に設けられる。分配部１１０のガス流路１１１の前端部は、調圧部１２０の内部を前後方向に延びるガス流路１５３の後端部に接続する。分配部１１０の前端部には、分配部１１０を調圧部１２０に固定する固定部１１３が形成される。ガス流路１１１は固定部１１３の前面において開口する。固定部１１３は固定部１５１と同様の左右方向に長い板状を呈し、左右両端部に、固定ネジ１５２のネジ穴が設けられる。固定部１１３と固定部１５１とは、固定ネジ１５２の締結によって互いに固定される。ガス流路１５３とガス流路１１１の接続部にはＯリング１５５が配設され、接続部におけるガス漏れが防止される。 Distributing section 110 is provided behind pressure adjusting section 120 . A front end portion of the gas channel 111 of the distribution portion 110 is connected to a rear end portion of a gas channel 153 extending in the front-rear direction inside the pressure adjusting portion 120 . A fixing portion 113 for fixing the distribution portion 110 to the pressure regulating portion 120 is formed at the front end portion of the distribution portion 110 . The gas flow path 111 opens at the front surface of the fixed portion 113 . The fixing portion 113 has a plate-like shape elongated in the left-right direction like the fixing portion 151 , and screw holes for fixing screws 152 are provided at both left and right ends thereof. The fixing part 113 and the fixing part 151 are fixed to each other by fastening the fixing screws 152 . An O-ring 155 is provided at the connection between the gas flow path 153 and the gas flow path 111 to prevent gas leakage at the connection.

ガス流路１１１の後端部は、分配部１１０の後部に設けられる分配室１１２に接続する。ガス流路１１１の上下においてガス流路１１１とは独立に形成される上側流路１１４と下側流路１１５は、図示しないが、夫々、分配室１１２に連通する。上側流路１１４は、上火バーナ３２にガスを供給する上火ガス管３５に接続する。下側流路１１５は、下火バーナ３３にガスを供給する下火ガス管３６に接続する。このように、上火バーナ３２及び下火バーナ３３に安定したガス圧でガスが供給されるので、グリルバーナの燃焼状態が安定する。なお、詳細な説明は省略するが、分配部１１０の後部には、上側流路１１４及び下側流路１１５に連通する分配室１１２内の流路を夫々独立に開閉することで、グリルバーナの火力を弱火力と強火力とに切替えるための電磁弁１１６及び電磁弁１１７が設けられる。電磁弁１１６，１１７は、操作つまみ１２の回転位置によって電磁弁１１６，１１７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。 A rear end portion of the gas channel 111 is connected to a distribution chamber 112 provided at the rear portion of the distribution section 110 . An upper channel 114 and a lower channel 115 , which are formed independently of the gas channel 111 above and below the gas channel 111 , respectively communicate with the distribution chamber 112 , although not shown. The upper flow path 114 connects to a top fire gas pipe 35 that supplies gas to the top fire burner 32 . The lower flow path 115 connects to an underfire gas pipe 36 that supplies gas to the underfire burner 33 . In this way, since the gas is supplied to the top flame burner 32 and the bottom flame burner 33 at a stable gas pressure, the combustion state of the grill burner is stabilized. Although the detailed description is omitted, in the rear part of the distribution section 110, by independently opening and closing the flow paths in the distribution chamber 112 communicating with the upper flow path 114 and the lower flow path 115, respectively, the thermal power of the grill burner can be obtained. A solenoid valve 116 and a solenoid valve 117 are provided for switching between low heat power and high heat power. The electromagnetic valves 116 and 117 can be individually driven according to the rotational position of the operation knob 12 to switch between high and low flames of the top burner 32 and the bottom flame burner 33 .

次に、ガバナ装置１００の動作を説明する。ダイヤフラム１３３に連結する弁体１３６は、ダイヤフラム１３３と共に調圧バネ１３４によって下方に付勢されている。燃料供給装置５２からガスが供給されていないとき、調圧バネ１３４の付勢力は、流入口１４３内で弁部と弁座１３７との間をガスが流通可能な間隙が形成されるように、調整ネジ１３５によって調整されている。燃料供給装置５２からガスが供給される場合、ガスは、流入口１４３内で弁部と弁座１３７との間を通って圧力室１４９に流入し、圧力室１４９内をガスで満たす。圧力室１４９内のガスは、排出口１４７から分配部１１０へ排出されるが、圧力室１４９に流入するガス量が排出されるガス量より多くなると、圧力室１４９のガス圧が高くなる。圧力室１４９のガス圧が高くなると、ガスがダイヤフラム１３３を押圧し、ダイヤフラム１３３は調圧バネ１３４の付勢力に抗して蓋体１３２の方向へ変位する。 Next, the operation of the governor device 100 will be described. A valve body 136 connected to the diaphragm 133 is urged downward together with the diaphragm 133 by a pressure regulating spring 134 . When gas is not supplied from the fuel supply device 52, the biasing force of the pressure regulating spring 134 is such that a gap is formed between the valve portion and the valve seat 137 in the inflow port 143 so that gas can flow. It is adjusted by adjusting screw 135 . When gas is supplied from the fuel supply device 52 , the gas passes between the valve portion and the valve seat 137 in the inflow port 143 and flows into the pressure chamber 149 to fill the pressure chamber 149 with gas. The gas in the pressure chamber 149 is discharged from the discharge port 147 to the distribution section 110. When the amount of gas flowing into the pressure chamber 149 exceeds the amount of gas discharged, the gas pressure in the pressure chamber 149 increases. When the gas pressure in the pressure chamber 149 increases, the gas presses the diaphragm 133 and the diaphragm 133 is displaced toward the lid 132 against the biasing force of the pressure adjusting spring 134 .

ダイヤフラム１３３が変位すると弁体１３６も蓋体１３２の方向へ移動するので、弁部と弁座１３７との間隙が小さくなる。弁部と弁座１３７との間隙が小さくなると、圧力室１４９に流入するガス量が減るので、圧力室１４９のガス圧が低くなる。蓋体１３２の方向へ変位していたダイヤフラム１３３は、調圧バネ１３４に付勢され、弁座部１４０の方向へ戻る。ダイヤフラム１３３と共に弁体１３６も弁座部１４０の方向へ移動するので、弁部と弁座１３７との間隙が大きくなる。これにより、圧力室１４９に流入するガス量が増えるので、圧力室１４９のガス圧が高くなり、上記同様に、弁部と弁座１３７との間隙が小さくなる。このように、圧力室１４９内のガス圧に応じてダイヤフラム１３３が変位し、ダイヤフラム１３３に連結する弁体１３６の弁部と弁座１３７との間隙が変化するので、圧力室１４９内に流入するガス量が調整され、分配部１１０に供給されるガスの流量が安定する。 When the diaphragm 133 is displaced, the valve body 136 also moves toward the lid body 132, so that the gap between the valve part and the valve seat 137 becomes smaller. As the gap between the valve portion and the valve seat 137 becomes smaller, the amount of gas flowing into the pressure chamber 149 decreases, so the gas pressure in the pressure chamber 149 decreases. Diaphragm 133 displaced toward lid 132 is urged by pressure regulating spring 134 to return toward valve seat portion 140 . Since the valve element 136 moves toward the valve seat portion 140 together with the diaphragm 133, the gap between the valve portion and the valve seat 137 increases. As a result, the amount of gas flowing into the pressure chamber 149 increases, so the gas pressure in the pressure chamber 149 increases, and the gap between the valve portion and the valve seat 137 becomes smaller as described above. In this manner, the diaphragm 133 is displaced according to the gas pressure in the pressure chamber 149, and the gap between the valve portion of the valve element 136 connected to the diaphragm 133 and the valve seat 137 changes, so gas flows into the pressure chamber 149. The amount of gas is adjusted, and the flow rate of the gas supplied to the distribution section 110 is stabilized.

次に、ガバナ装置１００の特徴部について説明する。ガスガバナ１３０の圧力室１４９を流通するガス圧の調整は、ガスコンロ１の製造時に行われるが、出荷後にもメンテナンス等で行われる場合がある。また、メンテナンスにおいてダイヤフラム１３３の交換等が行われる場合、蓋体１３２が弁座部１４０から取り外される場合もある。 Next, features of the governor device 100 will be described. The adjustment of the gas pressure flowing through the pressure chamber 149 of the gas governor 130 is performed when the gas stove 1 is manufactured, but it may be performed for maintenance or the like even after shipment. Further, when the diaphragm 133 is replaced in maintenance, the lid body 132 may be removed from the valve seat portion 140 in some cases.

図２、図４に示すように、筐体２内において、ガバナ装置１００の分配部１１０は、燃料供給装置５２の後方側に配置される。第一梁部材４１は、燃料供給装置５２の後側本体５２Ｂの上方に位置する。よって分配部１１０は、右バーナ４の下方に配置され、右バーナ４の前側底部を支持する第一梁部材４１の後方且つ下方に配置される。調圧部１２０に延伸部１５０を設けたことによって、ガスガバナ１３０は、筐体２内において分配部１１０のすぐ前の位置よりも前方に配置され、燃料供給装置５２の後側本体５２Ｂの上側に配置される。ガスガバナ１３０が配置される位置は、第一梁部材４１の直下よりもやや前側の位置である。右バーナ４は、第一梁部材４１よりも後側に位置するので、ガスガバナ１３０は、ガスコンロ１の天板３を外した場合に、筐体２の前方斜め上方へ向けて開口部２５を介して露出することができる。 As shown in FIGS. 2 and 4 , the distributor 110 of the governor device 100 is arranged behind the fuel supply device 52 in the housing 2 . The first beam member 41 is positioned above the rear body 52B of the fuel supply device 52 . Therefore, the distribution section 110 is arranged below the right burner 4 and behind and below the first beam member 41 that supports the front bottom portion of the right burner 4 . By providing the extended portion 150 in the pressure regulating portion 120, the gas governor 130 is arranged in the housing 2 more forward than the position immediately in front of the distributing portion 110 and above the rear main body 52B of the fuel supply device 52. placed. The position where the gas governor 130 is arranged is a position slightly forward from directly below the first beam member 41 . Since the right burner 4 is located on the rear side of the first beam member 41, the gas governor 130 extends forward and obliquely upward of the housing 2 through the opening 25 when the top plate 3 of the gas stove 1 is removed. can be exposed.

図２、図４～図６に示すように、に示すように、ガスガバナ１３０の弁座部１４０は、蓋体１３２の基部１３１に対する受部１４１の合わせ面が、垂直方向の上方に対して前方斜め上方に傾斜する傾斜方向Ａを向く。より具体的には、受部１４１の縁部（合わせ面の外縁）を仮に傾斜方向Ａに上方へ延ばした柱状の仮想柱Ｑを想定すると、仮想柱Ｑは、筐体２の開口部２５において、第一梁部材４１と筐体２の前壁部２３との間隙Ｄ内に位置する。なお、仮想柱Ｑの柱軸は、傾斜方向Ａに沿う。蓋体１３２の基部１３１と弁座部１４０の受部１４１とを締結する固定ネジ１３８は、受部１４１の合わせ面に対して直交する向きに締結される。よって、固定ネジ１３８の固定方向に沿って仮に上方へ延びる仮想線Ｔは、仮想柱Ｑの柱軸と同じ傾斜方向Ａに沿い、且つ合わせ面内に位置するので、筐体２の開口部２５においては仮想柱Ｑ内を通り、よって間隙Ｄ内に位置する。 As shown in FIGS. 2 and 4 to 6, the valve seat portion 140 of the gas governor 130 is such that the mating surface of the receiving portion 141 with the base portion 131 of the lid body 132 faces forward in the vertical direction. It faces the inclination direction A which inclines diagonally upwards. More specifically, assuming a columnar virtual column Q in which the edge of the receiving portion 141 (the outer edge of the mating surface) extends upward in the inclination direction A, the virtual column Q is formed at the opening 25 of the housing 2. , within the gap D between the first beam member 41 and the front wall portion 23 of the housing 2 . Note that the column axis of the virtual column Q extends along the tilt direction A. As shown in FIG. A fixing screw 138 for fastening the base portion 131 of the lid 132 and the receiving portion 141 of the valve seat portion 140 is fastened in a direction perpendicular to the mating surface of the receiving portion 141 . Therefore, the imaginary line T that tentatively extends upward along the fixing direction of the fixing screw 138 is along the same inclination direction A as the column axis of the imaginary column Q and is positioned within the mating plane. , passes through the virtual column Q and is therefore located in the gap D.

また、調整ネジ１３５の調整方向は、調整ネジ１３５の軸方向である。調整ネジ１３５は、ダイヤフラム１３３に付与する調圧バネ１３４の付勢力を、弁体１３６の軸部の延びる方向に調整する。ダイヤフラム１３３が合わせ面に直交する方向に変位するように、弁体１３６の軸部は、傾斜方向Ａに沿って配置される。よって、調整ネジ１３５の調整方向に沿って仮に上方へ延びる仮想線Ｓは、傾斜方向Ａに沿う。そして、仮想線Ｓは、仮想線Ｔと同様に合わせ面内に位置するので、筐体２の開口部２５においては仮想柱Ｑ内を通り、よって間隙Ｄ内に位置する。 Also, the adjusting direction of the adjusting screw 135 is the axial direction of the adjusting screw 135 . The adjusting screw 135 adjusts the biasing force of the pressure adjusting spring 134 applied to the diaphragm 133 in the direction in which the shaft portion of the valve body 136 extends. The shaft portion of the valve body 136 is arranged along the inclination direction A so that the diaphragm 133 is displaced in the direction perpendicular to the mating surface. Therefore, the imaginary line S tentatively extending upward along the adjustment direction of the adjusting screw 135 is along the inclination direction A. As shown in FIG. Since the imaginary line S is positioned within the mating plane like the imaginary line T, it passes through the imaginary column Q at the opening 25 of the housing 2 and is therefore positioned within the gap D. FIG.

したがって、ガバナ装置１００を筐体２に組み付けるとき、あるいはガスガバナ１３０の調整を行う時、作業者は、開口部２５の間隙Ｄ内にドライバ等の調整道具を前方斜め上方から真っ直ぐ差し込んで、固定ネジ１３８の締結や調整ネジ１３５の調整を行うことができる。更に、メンテナンスにおいて蓋体１３２を弁座部１４０から取り外した場合、間隙Ｄを介して開口部２５から蓋体１３２を筐体２外に取り出すことができる。 Therefore, when assembling the governor device 100 to the housing 2 or adjusting the gas governor 130, an operator inserts an adjusting tool such as a screwdriver straight into the gap D from the front obliquely above the opening 25, and then tightens the fixing screw. 138 can be tightened and the adjustment screw 135 can be adjusted. Further, when the lid body 132 is removed from the valve seat portion 140 for maintenance, the lid body 132 can be taken out of the housing 2 through the opening 25 through the gap D.

また、弁座部１４０は、延伸部１５０の前端の位置よりも上方に形成される。これに対し、固定部１５１は、延伸部１５０の本体部分と上下方向において同じ高さ位置に設けられている。調圧部１２０を分配部１１０に固定する固定ネジ１５２は、固定部１５１において、延伸部１５０の左右方向の側方において締結される。固定ネジ１５２の固定方向は、調圧部１２０の固定部１５１と分配部１１０の固定部１１３の合わせ面に直交し、延伸部１５０内に形成されたガス流路１５３に沿う前後方向である。よって、固定ネジ１５２の固定方向に沿って仮に前方へ延びる仮想線Ｕは、延伸部１５０の左右方向の側方、且つ弁座部１４０よりも下方に位置する。故に、ガバナ装置１００の組み立て時、作業者はドライバ等の固定道具を調圧部１２０の前方から弁座部１４０の左右両側且つ下方を通る仮想線Ｕに沿って真っ直ぐ差し込んで、固定ネジ１５２の締結を行うことができる。 Also, the valve seat portion 140 is formed above the position of the front end of the extending portion 150 . On the other hand, the fixing portion 151 is provided at the same height position as the main portion of the extending portion 150 in the vertical direction. Fixing screws 152 for fixing pressure regulating portion 120 to distribution portion 110 are fastened at fixing portions 151 on lateral sides of extension portion 150 . The fixing screw 152 is fixed in the longitudinal direction along the gas flow path 153 formed in the extending portion 150 at right angles to the mating surfaces of the fixing portion 151 of the pressure adjusting portion 120 and the fixing portion 113 of the distribution portion 110 . Therefore, an imaginary line U tentatively extending forward along the fixing direction of the fixing screw 152 is positioned laterally of the extending portion 150 and below the valve seat portion 140 . Therefore, when assembling the governor device 100, an operator inserts a fixing tool such as a screwdriver straight from the front of the pressure regulating portion 120 along the imaginary line U that passes through both the left and right sides of the valve seat portion 140 and below, and tightens the fixing screw 152. A contract can be made.

また、図６、図７に示すように、弁座部１４０の突出部１４５は、傾斜方向Ａの反対側へ向けて突出する。そして平面部１４６は、流入口１４３が延びる斜め方向に対して直交する。流入口１４３は、弁体１３６が変位する傾斜方向Ａに沿って延びる。弁体１３６の弁部を受ける弁座１３７は、製造時に傾斜方向Ａに沿って流入口１４３に圧入されることによって、弁座部１４０に組み付けられる。弁座１３７の圧入時、弁座部１４０は、弁座１３７の圧入方向すなわち傾斜方向Ａを上下方向にして、上方を向く水平面を有する圧入用の治具１８０にセットされる。このとき、突出部１４５の平面部１４６は、圧入用の治具１８０の水平面上に配置され、上下方向に対して直交するので、弁座部１４０を平面によって確実に支えることができる。故に弁座１３７は、弁座部１４０が安定して支えられ、且つ圧入方向を流入口１４３が延びる傾斜方向Ａに沿わせた状態で流入口１４３に圧入されるので、流入口１４３に確実に固定される。 6 and 7, the protruding portion 145 of the valve seat portion 140 protrudes toward the opposite side of the inclination direction A. As shown in FIGS. The plane portion 146 is orthogonal to the oblique direction in which the inlet 143 extends. The inflow port 143 extends along the inclination direction A in which the valve body 136 is displaced. A valve seat 137 that receives the valve portion of the valve body 136 is assembled to the valve seat portion 140 by being press-fitted into the inlet 143 along the inclination direction A during manufacturing. When the valve seat 137 is press-fitted, the valve seat portion 140 is set in a press-fitting jig 180 having a horizontal surface facing upward, with the press-fitting direction of the valve seat 137, that is, the inclination direction A being the vertical direction. At this time, the plane portion 146 of the projecting portion 145 is arranged on the horizontal plane of the jig 180 for press-fitting and is perpendicular to the vertical direction, so that the valve seat portion 140 can be reliably supported by the plane. Therefore, the valve seat 137 is press-fitted into the inflow port 143 in a state in which the valve seat portion 140 is stably supported and the press-in direction is aligned with the inclined direction A in which the inflow port 143 extends. Fixed.

また、ガスコンロ１の製造時、筐体２にガバナ装置１００を組み付ける前に、あらかじめガバナ装置１００を組み立てる場合、弁座部１４０に蓋体１３２を固定ネジ１３８で固定する作業が行われる。この場合においても、例えば弁座部１４０を治具１８０にセットすることで、固定ネジ１３８の固定方向を垂直方向にしてガバナ装置１００の組立作業を行うことができるので、蓋体１３２の固定をより確実に行うことができる。 Further, when the governor device 100 is assembled in advance before the governor device 100 is assembled to the housing 2 at the time of manufacturing the gas stove 1, an operation of fixing the lid body 132 to the valve seat portion 140 with the fixing screw 138 is performed. Even in this case, for example, by setting the valve seat portion 140 on the jig 180, the assembly work of the governor device 100 can be performed with the fixing screw 138 fixed in the vertical direction. can be done more reliably.

以上説明したように、ガバナ装置１００のガスガバナ１３０は、天板３を外した状態において、筐体２の開口部２５を介して上方へ向けて露出する。ガス圧の調整やガスガバナ１３０の修理を行う場合、天板３の他に他の部品を取り外す必要がないので、作業者は調整や修理の作業を容易に行うことができる。 As described above, the gas governor 130 of the governor device 100 is exposed upward through the opening 25 of the housing 2 when the top plate 3 is removed. When adjusting the gas pressure or repairing the gas governor 130, there is no need to remove other parts besides the top plate 3, so the operator can easily perform the adjustment and repair work.

ガス圧の調整やガスガバナ１３０の修理を行う場合、作業者は、ガスコンロ１の前側から作業を行う。ガスガバナ１３０は、蓋体１３２に対する弁座部１４０の合わせ面が、傾斜方向Ａの上方を向く。すなわち、弁座部１４０の合わせ面は、作業者が作業を行う時に、ガスガバナ１３０を見たり、工具を差し込んだりする方向を向く。よって作業者は、ガスガバナ１３０のガス圧の調整や修理の作業を容易に行うことができる。 When adjusting the gas pressure or repairing the gas governor 130 , the operator performs the work from the front side of the gas stove 1 . In the gas governor 130, the mating surface of the valve seat portion 140 with respect to the lid body 132 faces upward in the inclination direction A. As shown in FIG. That is, the mating surface of the valve seat portion 140 faces the direction in which the operator looks at the gas governor 130 or inserts a tool when performing work. Therefore, the operator can easily adjust the gas pressure of the gas governor 130 and perform repair work.

ガスコンロ１の筐体２内の上部にはコンロバーナが設けられる。右バーナ４を支持する第一梁部材４１は開口部２５に架設される。第一梁部材４１は右バーナ４の前側底部を支持するので、作業者は、第一梁部材４１と筐体２の前側縁部との間隙Ｄから、筐体２内に工具を差し込むことができる。ガスガバナ１３０のガス圧の調整は、調整ネジ１３５の操作によって行われる。作業者は、調整ネジ１３５の調整方向に沿って工具を真っすぐ開口部２５に差し込み、間隙Ｄを通すことができるので、ガス圧の調整を容易に行うことができる。また、蓋体１３２は、固定ネジ１３８を外すことによって弁座部１４０から取り外される。作業者は、固定ネジ１３８の固定方向に沿って工具を真っすぐ開口部２５に差し込み、間隙Ｄを通すことができるので、ガスガバナ１３０の修理を容易に行うことができる。 A stove burner is provided in the upper part of the housing 2 of the gas stove 1 . A first beam member 41 that supports the right burner 4 is installed across the opening 25 . Since the first beam member 41 supports the front bottom portion of the right burner 4, the operator can insert the tool into the housing 2 through the gap D between the first beam member 41 and the front edge of the housing 2. can. Adjustment of the gas pressure of the gas governor 130 is performed by operating the adjusting screw 135 . Since the operator can insert the tool straight into the opening 25 along the adjusting direction of the adjusting screw 135 and pass it through the gap D, the gas pressure can be easily adjusted. Also, the lid 132 is removed from the valve seat portion 140 by removing the fixing screw 138 . The operator can insert the tool straight into the opening 25 along the fixing direction of the fixing screw 138 and pass it through the gap D, so that the gas governor 130 can be easily repaired.

蓋体１３２を弁座部１４０から取り外す時、作業者は、蓋体１３２を傾斜方向Ａに取り出せば、他の部品に引っ掛かることなく、開口部２５において間隙Ｄを通して筐体２から取り外すことができる。故に作業者は、ガスガバナ１３０の修理を容易に行うことができる。 When removing the lid 132 from the valve seat portion 140, the operator can remove the lid 132 from the housing 2 through the gap D at the opening 25 by taking it out in the inclination direction A without being caught by other parts. . Therefore, the operator can easily repair the gas governor 130 .

調圧部１２０と分配部１１０は、固定ネジ１５２を用いて互いに固定する。ガスガバナ１３０は弁座部１４０の合わせ面が上方に対して傾斜するが、固定ネジ１５２を固定する工具の使用において、工具に干渉しない。よってガスコンロ１の製造過程において、作業者はガバナ装置１００の組み立てを容易に行うことができる。 The pressure adjusting section 120 and the distributing section 110 are fixed to each other using a fixing screw 152 . The mating surface of the valve seat portion 140 of the gas governor 130 is inclined upward, but when a tool for fixing the fixing screw 152 is used, it does not interfere with the tool. Therefore, in the manufacturing process of the gas stove 1, an operator can easily assemble the governor device 100. FIG.

ガスコンロ１の製造過程において、弁座部１４０には、弁体１３６を受ける弁座１３７が圧入される。弁座部１４０は合わせ面が上方に対して斜めを向くので、弁座１３７の圧入方向も斜めになる。弁座部１４０に設けた突出部１４５は、平面部１４６が圧入方向に直交するので、圧入用の治具１８０に平面部１４６を水平に支持させることによって、圧入方向を上下方向にすることができる。よってガスコンロ１の製造過程において、作業者は弁座部１４０に弁座１３７を容易に圧入することができる。 During the manufacturing process of the gas stove 1 , a valve seat 137 that receives the valve body 136 is press-fitted into the valve seat portion 140 . Since the mating surface of the valve seat portion 140 is slanted upward, the press-fit direction of the valve seat 137 is also slanted. Since the flat portion 146 of the projecting portion 145 provided on the valve seat portion 140 is perpendicular to the press-fitting direction, the press-fitting direction can be made vertical by horizontally supporting the flat portion 146 on the jig 180 for press-fitting. can. Therefore, in the manufacturing process of the gas stove 1 , the operator can easily press-fit the valve seat 137 into the valve seat portion 140 .

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。弁座部１４０の合わせ面が向く傾斜方向Ａの傾斜角度は適宜設定可能である。仮想柱Ｑは、間隙Ｄ内に完全に位置する必要はなく、一部は間隙Ｄからはみ出していてもよい。弁座部１４０に蓋体１３２を固定する固定ネジ１３８の固定方向に沿う仮想線Ｔと、調整ネジ１３５の調整方向に沿う仮想線Ｓは、間隙Ｄ内に位置すれば、必ずしも傾斜方向Ａに沿っていなくてもよい。また、調圧部１２０と分配部１１０を固定する固定ネジ１５２の固定方向は、固定時に工具がガスガバナ１３０の下方を通り、ガスガバナ１３０に干渉しなければ、必ずしも前後方向に沿わなくてもよい。 The present invention is not limited to the above embodiments, and various modifications are possible. The inclination angle of the inclination direction A in which the mating surface of the valve seat portion 140 faces can be set appropriately. The virtual pillar Q does not need to be positioned completely within the gap D, and may partially protrude from the gap D. A virtual line T along the fixing direction of the fixing screw 138 that fixes the lid 132 to the valve seat portion 140 and a virtual line S along the adjusting direction of the adjusting screw 135 are necessarily aligned in the tilt direction A if positioned within the gap D. It doesn't have to be along. The fixing screw 152 for fixing the pressure regulating part 120 and the distributing part 110 does not necessarily have to be fixed in the longitudinal direction unless the tool passes under the gas governor 130 and does not interfere with the gas governor 130 when fixing.
