Description

【0001】
【発明の属する技術分野】
本発明は、ガスコンロ等のガス調理器具に設けたガスバーナへの燃料ガスの供給を制御するガス制御装置に関する。
【0002】
【従来の技術】
この種のガス制御装置では、ガスバーナを点火する際、ガスバーナの火力を所定火力にするため、ガスバーナの点火、消火を行う点消火ボタンと、ガスバーナへの燃料ガス供給量を調節する火力調節ダイヤルとをそれぞれ設け、点消火ボタンの前後方向の移動で火力調節ダイヤルが所定位置まで回転されるようにしたものが知られている(特許文献1)。
【0003】
この場合、点消火ボタンは、円筒形状に形成され、例えばガスコンロ前面の操作パネルに前後方向に移動自在に設けられる。点消火ボタンの前後方向の異なる3つの位置には、ガスバーナに連なるガス通路を開放保持する開弁位置と、ガスバーナの点火手段を作動させる点火位置と、ガス通路を閉鎖する閉弁位置とが設けられている。また、点消火ボタンの周囲には、点消火ボタンの開弁位置でガスバーナへの燃料ガス供給量の調節を可能とする回転自在なリング状の火力調節ダイヤルが操作パネルから前方側に突出させて設けられている。
【0004】
そして、閉弁位置から点消火ボタンを押込み操作すると、点消火ボタンが点火位置に移動し、ガス通路を開放すると共にガスバーナの点火手段を作動させる。ガスバーナが着火したことを確認して点消火ボタンの押込みを解除すると、点消火ボタンは突出して開弁位置に移動する。開弁位置では、火力調節ダイヤルによってガスバーナの火力調節が可能になる。ガスバーナの燃焼を停止する場合、開弁位置に在る点消火ボタンを押込み操作して閉弁位置まで移動させると、ガス通路が閉鎖されてガスバーナが消火される。
【0005】
【特許文献1】
特許2742356号公報(例えば、特許請求の範囲の記載)
【0006】
【発明が解決しようとする課題】
しかしながら、上記のものでは、ガスバーナの使用時、点消火ボタンがガスコンロ前面の操作パネルから大きく突出しているので、特に点消火ボタンに、例えば調理時に生じた煮こぼれやガスコンロに一体に設けたグリルからの油煙等による汚れやごみが付着し易く、場合によっては煮汁が点消火ボタンを伝ってガスコンロ内に侵入して電装基板やスイッチなどの悪影響を及ぼす可能性があった。
【0007】
また、付着したごみをそのままにすると、点消火ボタンによる消火操作の際、点消火ボタンによってごみがガスコンロ内に持ち込まれて、上記と同様、電装基板やスイッチなどの悪影響を及ぼしたり、火力調節ダイヤルの円滑な回転運動をを阻害したりする。
【0008】
そこで、本発明は、上記点に鑑み、ガス調理器具の使用中に点消火ボタンに煮こぼれ、ごみや汚れが付着し難く、その上、煮汁やごみがガスコンロ内に持ち込まれて電装基板やスイッチなどの悪影響を及ぼしたり、火力調節ダイヤルの円滑な回転移動を阻害したりすることが防止できるガス制御装置を提供することを課題とする。
【0009】
【課題を解決するための手段】
上記課題を解決するために、本発明のガス制御装置は、ガスバーナに通じるガス通路を開放保持する開弁位置、ガスバーナの点火手段を作動させる点火位置及びガス通路を閉鎖する閉弁位置の間で前後方向に移動自在な点消火ボタンを備え、この点消火ボタンの周囲に、ガスバーナへの燃料ガス供給量の調節を可能とする回転自在なリング状の火力調節ダイヤルを設けたガス制御装置において、前記閉弁位置から点火位置に点消火ボタンを移動させた場合、前記火力調節ダイヤルが点消火ボタンの前後方向の移動と共に移動するように構成し、前記閉弁位置から点火位置への点消火ボタンの移動に伴ってガスバーナへの燃料ガス供給量を所定量に設定する位置まで火力調節ダイヤルを強制的に回転させる強制回転手段を設けたことを特徴とする。
【0010】
この場合、前記点消火ボタン及び火力調節ダイヤルは、ガス調理器具の操作パネルから突出して設けられ、点消火ボタンの押込み操作で閉弁位置から点火位置を経て開弁位置に移動し、この開弁位置で前記点消火ボタン及び火力調節ダイヤルは、閉弁位置より後方側に押込まれた位置で操作パネルから突出するようにすればよい。
【0011】
この発明によれば、閉弁位置では、点消火ボタンの外周面が火力調節ダイヤルで隠され、閉弁位置から点消火ボタンを押込み操作すると、火力調節ダイヤルも一緒に後方側に移動する。点消火ボタンが点火位置に到達すると、ガス通路が開放されてガスバーナに燃料ガスが流れ、点火手段が作動する。点火手段による点火操作が終了して点消火ボタンの押込みを解除すると、点消火ボタンは、ガス通路を開放状態に保持する開弁位置に到達する。
【0012】
開弁位置で点消火ボタン及び火力調節ダイヤルが閉弁位置より後方側に押込まれているようにする場合も、開弁位置において点消火ボタンの外周面が火力調節ダイヤルでカバーされている。このため、例えば調理時に煮こぼれが生じても火力調節ダイヤルや点火消火ボタンに煮汁や汚れが付着し難くなると共に、点消火ボタンを伝って煮汁がガス調理器具内に侵入するのが防止される。
【0013】
そして、火力調節ダイヤルを火力調節範囲内で回転させると、ガスバーナに供給される燃料ガスのガス流量が増減されて火力が調節できる。ガスバーナを消火するために、点消火ボタンを操作して開弁位置から閉弁位置に移動させると、点消火ボタン及び火力調節ダイヤルがガス調理器具の前面パネルから突出した位置に戻ると共にガス通路が閉鎖されてガスバーナへの燃料ガスの供給が停止される。
【0014】
この場合、前記点消火ボタン及び火力調節ダイヤルの前方側の端面を略面一としておけば、火力調節ダイヤルに煮汁がかかっても、その周囲を伝って煮汁が下方に落下するだけで、点消火ボタンに煮汁がかからず有利である。
【0015】
また、前記点消火ボタンの外周面と火力調節ダイヤルの内周面との間に、その全周にわたって空間を設けておけば、点消火ボタンと火力調節ダイヤルとの間にごみが固着することで、点消火ボタンの押込み操作による火力調節ダイヤルの円滑な強制回転移動が阻害されることが防止される。
【0016】
ところで、誤った点火操作として、火力調節ダイヤルを把持して押込み操作が行われることが考えられる。この場合、点消火ボタンが前後方向に移動したのでは強制回転手段が破損される可能性がある。このため、前記点消火ボタンの閉弁位置で、火力調節ダイヤルを点消火ボタンの外周面を露出する方向に単独で移動可能としておけば、誤って火力調節ダイヤルを把持して押込み操作しても点消火ボタンが移動しないので強制回転手段を破損することが防止される。また、点消火ボタンの外周面にごみが付着した場合、閉弁位置で火力調節レバーを移動させれば、点消火ボタンの外周面を清掃できる。
【0017】
尚、前記火力調節ダイヤルを透明な部材で形成し、火力調節ダイヤルの内側に光を反射する反射層を設けると共に、この火力調節ダイヤルに向かって光を照射する光源を設け、点消火ボタンの開弁位置で、光源から光を照射して火力調節ダイヤルが光るようにすれば、ガス調理器具の作動状況を視覚で確認できてよい。
【0018】
この場合、前記反射層を、前記火力調節ダイヤルと点消火ボタンとの間に設けた反射部材の外表面に形成すれば、例えば火力調節ダイヤルの外周面に、ガスバーナの火力を指標する指標部を反射部材の一部を突出させて形成でき、この指標部のみが光らない構成を容易に実現できる。
【0019】
また、前記火力調節ダイヤルの前方側の縁部を、面取り部としておけば、火力調節ダイヤルに光源から光りを照射したとき、この面取り部がリング状に光ってよい。
【0020】
【発明の実施の形態】
図1を参照して、1は、本発明のガス制御装置であり、このガス制御装置1は、ガス調理器具として例えばキッチンに設けた厨房家具に設置されるビルトイン式のガスコンロ2に組込まれる。ガスコンロ2は箱状のコンロ器体21を有し、コンロ器体21には、その上面を覆う天板22に設けた3個の開口を臨むように3個のガスバーナ23が設けられている。コンロ器体21の前面の両端には、操作パネルである前面パネル24が設けられている。また、コンロ器体21には、両前面パネル24の間に位置して、セラミックプレート式バーナ(図示せず)を設けたグリル25が設けられている。そして、本発明のガス制御装置1によって3個のガスバーナ23及びセラミックスプレート式バーナへの燃料ガスの供給が制御される。
【0021】
図2を参照して、ガス制御装置1は、上下に重ねて連結した2個の部分11a、11bから構成されるバルブケーシングを有する。下側に位置するバルブケーシングの第1部分11aには、バルブケーシングの長手方向に沿って延びる第1内部通路12aが設けられ、第1内部通路12aに連通するガス流入部13が開設されている。ガス流入部13の下流側に位置して第1内部通路12aには電磁安全弁3が設けられている。電磁安全弁3はマグネットケース31を有し、このマグネットケース31には、例えばコンロ器体21に設けた制御ユニット(図示せず)からの信号に基づいて励磁される電磁石とこれに吸着される吸着片とが収容されている。
【0022】
吸着片にはマグネットケース31から第1内部通路12aの下流側に向かって突出した第1弁体32が連結されている。電磁安全弁3の閉弁状態では、第1弁体32は、該第1弁体32とマグネットケース31との間に縮設したばね33の付勢力によって、シール材34aを介して第1内部通路12aに設けた弁座部材34の弁座に着座している。電磁安全弁3の開弁操作は、シール材41を介して第1内部通路12aに挿設され、第1内部通路12aの長手方向に沿って前後方向に移動自在な操作ロッド4により行われる。操作ロッド4には第2弁体42が設けられ、第2弁体42は第1内部通路12aに設けた弁座43と共に元弁を構成する。元弁の閉弁状態では、第2弁体42は、第2弁体42と弁座部材34との間に縮設したばね44により弁座43に着座している。
【0023】
操作ロッド4の前後方向の移動は、前面パネル24に設けられる点消火ボタン5の押込み操作によって行われる。点消火ボタン5は円筒形状に形成され、その第1内部通路12a側の端面には、点消火ボタン5の移動に伴って操作ロッド4を押圧する押圧ロッド51が連結されている。押圧ロッド51の下側には、案内部51aが連結され、この案内部51aの一端は、第1部分11aの下側に設けたハートカム機構52に連結されている。
【0024】
図2乃至図4に示すように、点消火ボタン5は、後述の火力調節ダイヤルと共に前面パネル24から突出し、第1内部通路12aを閉鎖する閉弁位置(図2参照)から点火操作を行うために、コンロ器体21内側に向かう方向である後方側(図2では右側)に点消火ボタン5を押込み操作すると、押圧ロッド51を介して操作ロッド4が後方側に押込まれて元弁を開弁させた後、弁体32を吸着片側に押しきると共に点火手段である放電ユニット(図示せず)が作動する点火位置まで移動する(図3参照)。点火位置から点消火ボタン5の押込みを解除すると、ハートカム機構52で案内されて、コンロ器体21外側に向かう方向である前方側(図3では左側)に移動して元弁を開弁保持して第1内部通路12aを開放した状態の開弁位置に到達する(図4参照)。消火操作を行うために開弁位置から点消火ボタン5をさらに押込み操作すると、ハートカム機構52がリセットされて消火位置に戻される(図1及び図2に示す状態)。
【0025】
元弁の上流側に位置して第1部分11aにはガス流出口14が設けられ、該ガス流出口14は、第2部分11bに設けた略L字形の第2内部通路12bの一端と一致し、第1及び第2の各内部通路12a、12bがガス通路を構成する。第2部分11bの外周面には、所定の間隔を置いて4個の第1、第2、第3及び第4の各連通路15a、15b、15c、15dが相互に隔絶して設けられている。各連通路15a、15b、15c、15dを介して、第2部分11bの上部に連結したガス流出部16と第2内部通路12bとが連通している。そして、ガス流出部16から流出した燃料ガスは、各ガスバーナ23及びセラミックプレート式バーナの各混合管に燃料ガスを噴射するガスノズル(図示せず)へと供給される。この場合、ガスノズルへの燃料ガスのガス供給量を調節するため、第2内部通路12bには流量調節弁6が設けられている。
【0026】
図2及び図5を参照して、流量調節弁6は、第2内部通路12bに回転自在に挿設した円筒形状の回転体61を有する。回転体61の外周面には、4本の円周方向の第1、第2、第3及び第4の各長溝62a、62b、62c、62dが、第1、第2、第3及び第4の各連通路15a、15b、15c、15dにそれぞれ対応させて形成されている。この場合、各長溝62a、62b、62c、62dの幅寸法は、各連通路15a、15b、15c、15dの孔径にそれぞれ一致させかつ円周方向にずらして形成している。この場合、各連通路15a、15b、15c、15dを通過してガス流出部16へと流れる燃料ガスのガス流量を所定量に調節する4個のオリフィス孔63a、63b、63c、63dを形成したオリフィス部材63を、各連通路15a、15b、15c、15dに一致させて第2部分11bの上面に装着している。そして、回転体61を回転させて各長溝62a、62b、62c、62dを各連通路15a、15b、15c、15dと適宜一致させてガス流出部16へと流れる燃料ガスのガス流量が調節される。回転体61の回転角の調節は、点消火ボタン5の周囲に設けたリング状の火力調節ダイヤル7により行われる。
【0027】
ところで、点消火ボタン5と火力調節ダイヤル7とはコンロ器体21の前面パネル24に設けられるが、開弁位置で点消火ボタン5が火力調節ダイヤル7から突出したのでは、例えば調理時に生じた煮こぼれやグリル25からの油煙等で汚れやごみが付着し易くなる。また、調理時に煮こぼれが生じた場合、その煮汁が点消火ボタン5にかかり、この点消火ボタン5を伝ってガスコンロ2内に侵入して電装基板やスイッチなどの悪影響を及ぼす可能性がある。
【0028】
図2及び図6を参照して、本実施の形態では、点消火ボタン5の外周面が火力調節ダイヤル7及び前面パネル24内に隠れるように、点消火ボタン5と火力調節ダイヤル7との前方側の端面を略面一とすると共に、前記点消火ボタン5の外周面と火力調節ダイヤル7の内周面との間にその全周にわたって空間Sを設けた。そして、閉弁位置では、点消火ボタン5と火力調節ダイヤル7とが一体となって前面パネル24から前方側に突出し、押込み操作で開弁位置に点消火ボタン5を移動させると、それに伴って火力調節ダイヤル7が後方側に移動するようにした。この場合、火力調節ダイヤル7は、調理者が火力調節ダイヤル7を操作してガスバーナ23の火力を調節できる長さだけ、前面パネル24から突出している。
【0029】
これにより、点消火ボタン5及び火力調節ダイヤル7は、閉弁位置より後方側に押込まれていると共に、点消火ボタン5の外周面が常時火力調節ダイヤル7で隠れているため、調理時に煮こぼれが生じても火力調節ダイヤル7に煮汁がかかり難くなり、火力調節ダイヤル7に煮汁がかかっても、その周囲を伝って煮汁が下方に落下するだけで、点消火ボタン5の外周面に煮汁が侵入しない。このため、点消火ボタン5を伝って煮汁がガスコンロ2内に侵入することが防止される。また、空間Sを設けたので、点消火ボタン5と火力調節ダイヤル7との間にごみが固着することで、点消火ボタン5の押込み操作による火力調節ダイヤル7の円滑な強制回転移動が阻害されることが防止される。
【0030】
火力調節ダイヤル7は、点消火ボタン5の前後方向の移動と共に移動する回転自在なつまみ部材71と、回転体61を回転させるダイヤル部材72を備えている。ダイヤル部材72の第1内部通路11a側の端部は所定ピッチで歯切りされ、歯切した部分72aが第2部分11bから突出した回転体61の一端部に嵌合した歯車Gと噛合っている。これにより、ダイヤル部材72の回転操作に同期して回転体61が回転される。また、ダイヤル部材72の他端部には、半径方向外側に延出させた凹部72bが相互に対向して2箇所設けられている。
【0031】
点消火ボタン5の外周面を隠すつまみ部材71は透明な樹脂性であり、その第1内部通路11a側の端部には、第1内部通路11a側に延びる突出片71aが相互に対向して2箇所設けられている。そして、各突出片71aが各凹部72b内を摺動自在に係合させてつまみ部材71とダイヤル部材72とが組付けられる。また、つまみ部材71の内側には、このつまみ部材71の内形にほぼ一致した反射部材73が装着されている。反射部材73の外表面には、アルミニウムをコーティングすることで反射層が形成されている。反射部材73にはまた、点消火ボタン5の外周面に形成した段部5aと、つまみ部材71の内周面に形成した段部71bとに同時に当接するつば部73aが形成され、このつば部73aとダイヤル部72との間に縮設したばね74によって反射部材73が前方側に付勢されている。
【0032】
これにより、つまみ部材71がばね74の付勢力で点消火ボタン5に押当てられ、点消火ボタン5を押込み操作すると、それに伴ってつまみ部材71が後方側に移動し、開弁位置では、つまみ部材71を回転させると、突出片71aと係合した凹部72bを介してダイヤル部材72が回転される。他方で、前記点消火ボタン5の閉弁位置では、火力調節ダイヤル7が点消火ボタン5の外周面を露出する方向に単独で移動可能となる。この場合、閉弁位置でつまみ部材71を移動させれば、点消火ボタン5の外周面が露出し、そこに付着したごみを清掃できる。また、火力調節ダイヤル7を把持して押込み操作しても点消火ボタン5が移動しないため、後述の強制回転手段が破損されることはない。さらに、反射部材73を設けたことで、点消火ボタン5の外周面にごみや汚れが付着してもこの反射部材73で隠されてよい。
【0033】
図7を参照して、前面パネル24の内側には、透明なつまみ部材71の上方から反射部材73に向かって光を照射するLED等の光源Eが設けられ、点消火ボタン5の開弁位置で、光源から光を照射してつまみ部材71が光るようにしている。これにより、ガスコンロ2の作動状況を視覚で確認できる。この場合、前記火力調節ダイヤル7の前方側の縁部を面取り部Cとし、ダイヤル部材71に光源Eから光を照射したとき、この面取り部Cでリング状に光るようにしている。また、反射部材73の表面には、長手方向に延びる凸部73bが形成され(図6参照)、この凸部73bが、つまみ部71に設けた長手方向の収納部71cに収納され、前面パネル24に表示されたガスバーナの火力位置と凸部73bとの一致により、ガスバーナ23の火力を指標する指標部を構成する。また、この指標部は光源Eからの光が照射されても光ることがないため、光っている周囲に対して浮き出る効果があり、調理者は火力位置と指標部との一致を認識し易い。
【0034】
図8乃至図12を参照して、ダイヤル部材72の後方側の内周面にはカム溝72cが形成され、このダイヤル部材72内を前後方向に移動する押圧ロッド51の外周面には、カム溝72cと対偶をなす2個の突起片51bが設けられ(図6参照)、カム溝72cと突起片51bが強制回転手段を構成する。この場合、カム溝72cの壁面の高さは、点消火ボタン5の押込み操作につれて一方から他方に向かって低くなるように形成されている。そして、ガスバーナ23の点火のため、閉弁位置から点消火ボタン5を押込み操作して開弁位置に到達すると、突起片51bがカム溝72cと係合し、この突起片51bが原動節となって従動節であるカム溝72cが形成されたダイヤル部材72を回転させ、点消火ボタン5が点火位置に到達したときに、着火を確実にする流量の燃料ガスがガスバーナ23に供給される位置まで回転される。本実施の形態では、強制回転手段51b、カム溝72cにより、火力調節ダイヤル7は、点消火ボタン5の押込み操作で中火位置まで強制的に回転される。
【0035】
この場合、点消火ボタン5の押込み操作を利用して火力調節ダイヤル7を回転させるので、例えば押圧ロッド51と第1部分11aとの間に縮設したばね17の付勢力を大きくする必要がなく、ガス制御装置1の構造を簡素化できる。また、電磁安全弁3を開弁するために点消火ボタン5の移動距離が長く設定される開弁位置と点火位置との間を、火力調節ダイヤル7の強制的な回転に流用しているため、必要な移動距離が短い閉弁位置と開弁位置との間の点消火ボタン5の移動距離に、火力調節ダイヤル7の強制的な回転のための距離を付加したものより、点消火ボタン5の前後方向の移動距離を短くできるため、操作感がよく、使い勝手がよい。
【0036】
点火位置では、放電ユニットを作動させてガスバーナ23が点火される。その後、点消火ボタン5の押込みを解除すると、ハートカム機構52に案内されてばね17の付勢力によって少し戻り、点消火ボタン5は開弁位置に到達する。開弁位置では、突起片51bとカム溝72cとの係合が解除され、ダイヤル部材72が、時計方向または反時計方向に回転自在となる。この場合、火力調節ダイヤル7を、時計方向に回転させるとガス流量が絞られ、反時計方向に回転させるとガス流量が増加するように回転体61が回転される。これにより、開弁位置での火力調節ダイヤル7の操作性は損なわず、調理者の回転操作感に悪影響を与えることはない。また、点消火ボタン5の押込みを解除したときの点消火ボタン5の戻りで突起片51bとカム溝72cとの係合が解除されるため、開弁位置で強制回転手段51bが火力調節ダイヤル7のカム溝72cに干渉しないようにする機構を別途設ける必要もないため、部品点数を増やす必要もない。
【0037】
火力調節ダイヤル7の回転範囲を制限するため、ダイヤル部材72のカム溝72cを形成した箇所に、相互に対向する2個の凸部72dが形成されている。火力調節ダイヤル7を回転させ、この凸部72dに各突起片51bが当接するまで反時計方向に回転させると、第2、第3及び第4の各長溝62b、62c、62dが第2、第3及び第4の各連通路15b、15c、15dにそれぞれ一致してガス流出部16へのガス量が最大となるように回転体61を配置している。他方で、この凸部72dに各突起片51bが当接するまで時計方向に回転させると、第1長溝62aが第1連通路15aとのみ一致し、ガス流出部16へのガス量が最小となるようにしている。これにより、開弁位置では、火力調節ダイヤル7が、ガス流出部16へのガス流量を最小にしてガスバーナ23の火力を小とする小火力と、ガス流量を最大にしてガスバーナ23の火力を強とする強火力との間の火力調節範囲内でのみ回転自在となる。これにより、火力調節ダイヤル7の回転範囲を制限するためのストッパ等を別個に設ける必要はなく、部品点数が減少して低コストにできる。
【0038】
図13に示すように、点消火ボタン5の閉弁位置では、突起片51bが、ダイヤル部材72のカム溝72cを形成した箇所より前方側に位置している。この場合、閉弁位置で火力調節ダイヤル7を火力調節範囲を超えて反時計方向に回転できるようにし、この位置では、突起片51bが凸部72dと対向する。これにより、点消火ボタン5を押込み操作しても、突起片51bが凸部72bの前面パネル24手前側の面に当接して閉弁位置から点火位置に点消火ボタン5が移動できないロック位置が形成され、チャイルドロックされる。この場合、ダイヤル部材72の外周面に突出部Eを設け(図8参照)、この突出部Eが第1部分11aに設けたストッパ(図示せず)に当接すると、ロック位置に到達する。
【0039】
図6及び図14を参照して、ダイヤル部材72の前方側の内周面には、同一円周方向上で所定の間隔を置いて第1、第2及び第3の各凹部72e、72f、72gが形成されている。点消火ボタン5の後方側の端部には、半径方向の孔5bが形成され、この孔5bには、円筒形状のクリック部材Cがダイヤル部材72の内周面に向かってばねC1で付勢させた状態で収納されている。そして、開弁位置で、火力調節ダイヤル7を回転させて所定の位置に到達すると、凹部72e、72f、72gにクリック部材52が嵌合してクリックを発生する。
【0040】
次に、本発明のガス制御装置1の作動を説明する。図2に示す閉弁位置から点消火ボタン5の押込み操作すると、押圧ロッド51を介して操作ロッド4を後方側に押圧して元弁を開弁させ、図3に示す開弁位置に到達すると突起片51bとカム溝72cとが係合し、弁体32を吸着片側に押しきる点火位置に到達する前に、火力調節ダイヤル7が中火位置まで回転される。この場合、回転体61は歯車Gを介して回転され、この位置では、第1、第2及び第3の各長溝62a、62b、62cが第1、第2及び第3の各連通路15a、15b、15cにそれぞれ一致し、ガスバーナ23の火力を中とするガス流量の燃料ガスがガス流出部16へ流れる(図5参照)。また、クリック部材Cは第2の凹部72fに嵌合している(図14参照)。
【0041】
点火位置に到達すると、放電ユニットによってガスバーナ23の点火操作が行われる。そして、ガスバーナ23の近傍に設けた火炎検出素子(図示せず)がガスバーナ23の火炎を検出すると、制御ユニットからの信号で電磁弁3が励磁されて開弁保持される。ガスバーナ23が着火したことを確認して点消火ボタン5の押込みを解除すると、点消火ボタン5は、ハートカム機構52に案内されて図3に示す開弁位置に到達する。
【0042】
ガスバーナ23の火力を強めるため、中火位置から反時計方向に回転させ、クリック部材Cは第3の凹部72gに嵌合すると、凸部72dに各突起片51bが当接する。この場合、第2、第3及び第4の各長溝62b、62c、62dが第2、第3及び第4の各連通路15b、15c、15dにそれぞれ一致し、ガスバーナ23の火力を強とするガス流量の燃料ガスがガス流出部16へ流れる(図15参照)。
【0043】
他方で、中火からガスバーナ23の火力を絞るため、火力調節ダイヤル7を時計方向に回転させ、クリック部材Cは第1の凹部72eに嵌合すると、第1及び第2の各長溝62a、62bが第1及び第2の各連通路15a、15bにそれぞれ一致し、ガスバーナ23の火力を弱とするガス流量の燃料ガスがガス流出部16へ流れる(図16参照)。次いで、凸部72dに各突起片51bが当接するまで火力調節ダイヤル7を時計方向に回転させると、第1長溝62aが第1連通路15aとのみ一致し、ガスバーナ23の火力を小とする最小ガス流量の燃料ガスがガス流出部16へ流れる(図17参照)。
【0044】
ガスバーナ23を消火する場合、開弁位置から後方側に点消火ボタン5を押込み操作すると、ハートカム機構52がリセットされ、点消火ボタン5は、ばね17の付勢力を受けて図2に示す閉弁位置まで後退する。この場合、押圧ロッド51の押圧が解除された操作ロッド4は、ばね34の付勢力を受けて前方側に移動し、元弁を閉弁する。元弁が閉弁されるとガスバーナ23への燃料ガスの供給が停止されて消火される。火炎検出素子によって火炎が消えたことを制御ユニットが認識すると電磁安全弁3が閉弁される。
【0045】
尚、本実施の形態では、反射部材73に反射層を形成したが、これに限定されるものではなく、例えばダイヤル部材72の内側に反射層を形成してもよい。また、本実施の形態では、中火位置で点火する場合について説明したが、これに限定されるものではなく、例えば強火位置で点火操作ができるようにカム溝を形成してもよい。さらに、本実施の形態では、ガスコンロ2の前面パネル24に点消火ボタン5及び力調節ダイヤル7を設けた場合について説明したが、オーブン、グリル等の他のガス調理器具に点消火ボタン及び火力調節ダイヤルを有する本発明のガス制御装置を使用してもよく、例えば、コンロ器体を覆う天板に操作パネルを設けたガスコンロに、点消火ボタン及び火力調節ダイヤルを有する本発明のガス制御装置を適用してもよい。
【0046】
【発明の効果】
以上説明したように本発明のガス制御装置は、ガス調理器具の使用中に点消火ボタンに煮こぼれ、ごみや汚れが付着し難く、その上、煮汁やごみがガスコンロ内に持ち込まれて電装基板やスイッチなどの悪影響を及ぼしたり、火力調節ダイヤルの円滑な回転移動 を阻害したりすることが防止できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gas control device that controls supply of fuel gas to a gas burner provided in a gas cooking appliance such as a gas stove.
[0002]
[Prior art]
In this type of gas control device, when igniting a gas burner, a point fire extinguishing button for igniting and extinguishing the gas burner in order to bring the heat of the gas burner to a predetermined thermal power, and a fire power adjusting dial for adjusting the amount of fuel gas supplied to the gas burner There is a known configuration in which the heating power adjustment dial is rotated to a predetermined position by moving the point fire button in the front-rear direction (Patent Document 1).
[0003]
In this case, the point fire extinguishing button is formed in a cylindrical shape, and is provided, for example, on the operation panel on the front surface of the gas stove so as to be movable in the front-rear direction. At three different positions in the front-rear direction of the point fire extinguishing button, there are provided a valve opening position for opening and holding a gas passage connected to the gas burner, an ignition position for activating ignition means of the gas burner, and a valve closing position for closing the gas passage. Have been.

[0005]

Japanese Patent No. 2742356 (for example, Claims)
[0006]
[Problems to be solved by the invention]
However, in the above, when the gas burner is used, the fire extinguishing button protrudes greatly from the operation panel on the front surface of the gas stove. In this case, dirt and dust due to oil smoke and the like easily adhere, and in some cases, the broth may enter the gas stove via the fire extinguishing button and adversely affect the electric board and the switch.
[0007]
Also, if the attached dust is left as it is, when the fire extinguishing operation is performed by the point fire extinguishing button, the dirt is brought into the gas stove by the point extinguishing button, similarly to the above, having an adverse effect on the electrical equipment board and the switch, etc. Or hinder the smooth rotation of the robot.
[0008]
In view of the above, the present invention has been made in consideration of the above points, so that during use of a gas cooker, the fire extinguishing button is spilled, and dirt and dirt are hardly adhered. It is an object of the present invention to provide a gas control device that can prevent adverse effects such as the above, and prevent smooth rotation of a heat power adjustment dial.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, the gas control device according to the present invention includes a valve opening position for opening and holding a gas passage leading to a gas burner, an ignition position for operating ignition means of the gas burner, and a valve closing position for closing the gas passage. A gas control device comprising a point fire extinguishing button movable in the front-rear direction, and a rotatable ring-shaped heating power adjustment dial provided around the point fire extinguishing button and capable of adjusting a fuel gas supply amount to a gas burner. When the point fire extinguishing button is moved from the valve closing position to the ignition position, the heating power adjustment dial is configured to move together with the forward and backward movement of the point extinguishing button, and the point fire extinguishing button is moved from the valve closing position to the ignition position. Characterized in that forced rotation means for forcibly rotating the heating power adjustment dial to a position where the fuel gas supply amount to the gas burner is set to a predetermined amount with the movement of the gas burner is provided. .
[0010]
In this case, the point fire extinguishing button and the heating power adjustment dial are provided so as to protrude from the operation panel of the gas cooking appliance, and move from the valve closing position to the valve opening position through the ignition position by the pushing operation of the point fire extinguishing button. In this position, the point fire extinguishing button and the heating power adjustment dial may protrude from the operation panel at a position pushed backward from the valve closing position.
[0011]
According to the present invention, at the valve closing position, the outer peripheral surface of the point fire extinguishing button is hidden by the heating power adjustment dial, and when the point fire extinguishing button is pressed from the valve closing position, the heating power adjusting dial also moves rearward together. When the point fire extinguishing button reaches the ignition position, the gas passage is opened, fuel gas flows into the gas burner, and the ignition means operates. When the ignition operation by the ignition means is completed and the pushing of the fire extinguishing button is released, the fire extinguishing button reaches the valve opening position for keeping the gas passage open.
[0012]
Also in the case where the point fire extinguishing button and the heating power adjustment dial are pushed backward from the valve closing position at the valve opening position, the outer peripheral surface of the point fire extinguishing button is covered with the heating power adjustment dial at the valve opening position. For this reason, for example, even if boiling occurs during cooking, it becomes difficult for the broth or dirt to adhere to the heating power adjustment dial or the ignition fire extinguishing button, and the broth is prevented from entering the gas cooking utensil via the point fire extinguishing button. .
[0013]
Then, when the heating power adjustment dial is rotated within the heating power adjustment range, the flow rate of the fuel gas supplied to the gas burner is increased or decreased, so that the heating power can be adjusted. When the fire extinguishing button is operated to move the valve from the open position to the closed position in order to extinguish the gas burner, the fire extinguishing button and the heating power adjustment dial return to a position protruding from the front panel of the gas cooking appliance, and the gas passage is opened. It is closed and the supply of fuel gas to the gas burner is stopped.
[0014]
In this case, if the front end surfaces of the fire extinguishing button and the heating power adjustment dial are substantially flush with each other, even if the broth is applied to the heating power adjustment dial, the broth simply falls down along the surroundings, thereby causing the fire extinguishing. It is advantageous because no broth is applied to the buttons.
[0015]
In addition, if a space is provided over the entire circumference between the outer peripheral surface of the point fire extinguishing button and the inner peripheral surface of the fire power adjusting dial, dust is fixed between the point fire extinguishing button and the fire power adjusting dial. Further, it is possible to prevent the smooth forced rotation of the heating power adjustment dial due to the pressing operation of the point fire button.
[0016]
By the way, it is conceivable that, as an erroneous ignition operation, a pushing operation is performed while holding the heating power adjustment dial. In this case, the forcible rotation means may be damaged if the point fire button is moved in the front-rear direction. Therefore, if the fire extinguishing button can be moved independently in the valve extinguishing position of the point fire extinguishing button in the direction in which the outer peripheral surface of the point extinguishing button is exposed, even if the fire adjusting dial is erroneously grasped and pushed in, Since the fire extinguishing button does not move, it is possible to prevent the forced rotation means from being damaged. Further, when dust adheres to the outer peripheral surface of the point fire extinguishing button, the outer peripheral surface of the point extinguishing button can be cleaned by moving the heating power control lever at the valve closing position.
[0017]
The heating power adjustment dial is formed of a transparent member, a reflection layer for reflecting light is provided inside the heating power adjustment dial, and a light source for irradiating light toward the heating power adjustment dial is provided. By irradiating light from the light source at the valve position to make the heating power adjustment dial glow, the operating state of the gas cooking appliance may be visually confirmed.
[0018]
In this case, if the reflection layer is formed on the outer surface of the reflection member provided between the fire power adjustment dial and the point fire extinguishing button, for example, on the outer peripheral surface of the heat power adjustment dial, an index portion for indicating the heat power of the gas burner is provided. A part of the reflecting member can be formed so as to protrude, and a configuration in which only the index portion does not emit light can be easily realized.
[0019]
In addition, if the front edge of the heating power adjustment dial is formed as a chamfered portion, when the heating power adjustment dial is irradiated with light from a light source, the chamfered portion may shine in a ring shape.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Referring to FIG. 1, reference numeral 1 denotes a gas control device of the present invention. The gas control device 1 is incorporated as a gas cooking appliance into a built-in gas stove 2 installed in kitchen furniture provided in a kitchen, for example. The gas stove 2 has a box-shaped stove body 21, and the stove body 21 is provided with three gas burners 23 so as to face three openings provided in a top plate 22 that covers the upper surface thereof. At both ends of the front surface of the stove body 21, front panels 24, which are operation panels, are provided. Further, the stove body 21 is provided with a grill 25 provided with a ceramic plate type burner (not shown), located between both front panels 24. Then, the supply of the fuel gas to the three gas burners 23 and the ceramic plate type burner is controlled by the gas control device 1 of the present invention.
[0021]
With reference to FIG. 2, the gas control device 1 has a valve casing composed of two parts 11a and 11b which are connected one above the other. The first portion 11a of the valve casing located on the lower side is provided with a first internal passage 12a extending along the longitudinal direction of the valve casing, and a gas inflow portion 13 communicating with the first internal passage 12a is opened. . An electromagnetic safety valve 3 is provided in the first internal passage 12a located downstream of the gas inflow section 13. The electromagnetic safety valve 3 has a magnet case 31. The magnet case 31 has, for example, an electromagnet which is excited based on a signal from a control unit (not shown) provided in the stove 21 and an attraction which is attracted to the electromagnet. A piece is housed.
[0022]
A first valve body 32 protruding from the magnet case 31 toward the downstream side of the first internal passage 12a is connected to the suction piece. When the electromagnetic safety valve 3 is in the closed state, the first valve body 32 causes the first internal passage through the seal member 34 a by the urging force of the spring 33 contracted between the first valve body 32 and the magnet case 31. It is seated on a valve seat of a valve seat member 34 provided in 12a. The valve opening operation of the electromagnetic safety valve 3 is performed by the operation rod 4 which is inserted into the first internal passage 12a via the seal member 41 and is movable in the front-rear direction along the longitudinal direction of the first internal passage 12a. The operation rod 4 is provided with a second valve body 42, and the second valve body 42 constitutes a main valve together with a valve seat 43 provided in the first internal passage 12a. In the closed state of the main valve, the second valve body 42 is seated on the valve seat 43 by a spring 44 contracted between the second valve body 42 and the valve seat member 34.
[0023]
The movement of the operation rod 4 in the front-rear direction is performed by pressing a point fire button 5 provided on the front panel 24. The fire extinguishing button 5 is formed in a cylindrical shape, and a pressing rod 51 that presses the operating rod 4 with the movement of the fire extinguishing button 5 is connected to the end face on the first internal passage 12a side. A guide portion 51a is connected to a lower side of the pressing rod 51, and one end of the guide portion 51a is connected to a heart cam mechanism 52 provided below the first portion 11a.
[0024]
As shown in FIGS. 2 to 4, the point fire extinguishing button 5 protrudes from the front panel 24 together with a heat power adjusting dial, which will be described later, to perform an ignition operation from a valve closing position (see FIG. 2) that closes the first internal passage 12a. Then, when the point fire extinguishing button 5 is pushed to the rear side (the right side in FIG. 2) which is the direction toward the inside of the stove body 21, the operating rod 4 is pushed rearward via the pressing rod 51 to open the main valve. After the valve is opened, the valve body 32 is pushed all the way to the attraction side, and moves to an ignition position where a discharge unit (not shown) as an ignition means operates (see FIG. 3). When the depression of the point fire button 5 is released from the ignition position, it is guided by the heart cam mechanism 52 and moves forward (to the left in FIG. 3), which is the direction toward the outside of the stove body 21, to hold the main valve open. As a result, the valve reaches the valve opening position where the first internal passage 12a is opened (see FIG. 4). When the point fire button 5 is further pushed in from the valve opening position to perform the fire extinguishing operation, the heart cam mechanism 52 is reset and returned to the fire extinguishing position (the state shown in FIGS. 1 and 2).
[0025]
A gas outlet 14 is provided in the first portion 11a located upstream of the main valve, and the gas outlet 14 is connected to one end of a substantially L-shaped second internal passage 12b provided in the second portion 11b. Accordingly, the first and second internal passages 12a and 12b constitute a gas passage. Four first, second, third, and fourth communication paths 15a, 15b, 15c, and 15d are provided at predetermined intervals on the outer peripheral surface of the second portion 11b so as to be isolated from each other. I have. The gas outlet 16 connected to the upper part of the second portion 11b and the second internal passage 12b communicate with each other via the communication passages 15a, 15b, 15c, and 15d. The fuel gas flowing out of the gas outlet 16 is supplied to a gas nozzle (not shown) for injecting the fuel gas into each gas burner 23 and each mixing pipe of the ceramic plate type burner. In this case, a flow control valve 6 is provided in the second internal passage 12b in order to control the gas supply amount of the fuel gas to the gas nozzle.
[0026]
Referring to FIGS. 2 and 5, the flow control valve 6 has a cylindrical rotating body 61 rotatably inserted into the second internal passage 12b. Four first, second, third, and fourth circumferential grooves 62a, 62b, 62c, 62d in the circumferential direction are formed on the outer peripheral surface of the rotating body 61, respectively, in the first, second, third, and fourth directions. Are formed corresponding to the communication paths 15a, 15b, 15c, and 15d, respectively. In this case, the width dimension of each of the long grooves 62a, 62b, 62c, and 62d is formed to be equal to the hole diameter of each of the communication passages 15a, 15b, 15c, and 15d, and to be shifted in the circumferential direction. In this case, four orifice holes 63a, 63b, 63c, 63d for adjusting the gas flow rate of the fuel gas flowing to the gas outlet 16 through the communication passages 15a, 15b, 15c, 15d to a predetermined amount were formed. The orifice member 63 is mounted on the upper surface of the second portion 11b so as to correspond to the communication paths 15a, 15b, 15c, and 15d. Then, by rotating the rotating body 61, the long grooves 62 a, 62 b, 62 c, and 62 d are appropriately matched with the communication paths 15 a, 15 b, 15 c, and 15 d, and the gas flow rate of the fuel gas flowing to the gas outlet 16 is adjusted. . The rotation angle of the rotating body 61 is adjusted by a ring-shaped heating power adjustment dial 7 provided around the point fire extinguishing button 5.
[0027]
By the way, the fire extinguishing button 5 and the heating power adjustment dial 7 are provided on the front panel 24 of the stove 21. If the fire extinguishing button 5 protrudes from the heating power adjustment dial 7 at the valve opening position, for example, it occurs during cooking. Dirt and garbage are more likely to adhere due to boiling over, oil smoke from the grill 25, and the like. In addition, when boiling occurs during cooking, the broth is applied to the fire extinguisher button 5 and may enter the gas stove 2 via the fire extinguishing button 5 to adversely affect the electrical board and the switch.
[0028]
Referring to FIGS. 2 and 6, in the present embodiment, front side of point fire extinguishing button 5 and fire power adjusting dial 7 is arranged such that the outer peripheral surface of point fire extinguishing button 5 is hidden in fire power adjusting dial 7 and front panel 24. The end face on the side was made substantially flush, and a space S was provided over the entire circumference between the outer peripheral surface of the point fire extinguishing button 5 and the inner peripheral surface of the heating power adjustment dial 7. In the valve closing position, the point fire extinguishing button 5 and the heating power adjustment dial 7 integrally project from the front panel 24 to the front side, and when the point fire extinguishing button 5 is moved to the valve opening position by the pushing operation, the fire extinguishing button 5 is moved. The heating power adjustment dial 7 is moved rearward. In this case, the heating power adjustment dial 7 protrudes from the front panel 24 by such a length that the cook can operate the heating power adjustment dial 7 to adjust the heating power of the gas burner 23.
[0029]
As a result, the fire extinguishing button 5 and the heating power adjustment dial 7 are pushed backward from the valve closing position, and the outer peripheral surface of the fire extinguishing button 5 is always hidden by the heating power adjustment dial 7, so that the fire extinguishing during cooking is spilled. Even if boil occurs, it becomes difficult for the broth to be applied to the heating power adjustment dial 7. Do not invade. For this reason, it is possible to prevent the boiling juice from entering the gas stove 2 along the fire extinguishing button 5. In addition, since the space S is provided, dust is stuck between the fire extinguishing button 5 and the heating power adjustment dial 7, and the smooth forced rotation of the heating power adjustment dial 7 by the pushing operation of the fire extinguishing button 5 is impeded. Is prevented.
[0030]
The heating power adjustment dial 7 includes a rotatable knob member 71 that moves with the forward and backward movement of the point fire button 5 and a dial member 72 that rotates the rotating body 61. The end of the dial member 72 on the first internal passage 11a side is cut at a predetermined pitch, and the cut portion 72a meshes with the gear G fitted to one end of the rotating body 61 protruding from the second portion 11b. I have. Thereby, the rotating body 61 is rotated in synchronization with the rotating operation of the dial member 72. The other end of the dial member 72 is provided with two concave portions 72b extending outward in the radial direction so as to face each other.
[0031]
The knob member 71 for hiding the outer peripheral surface of the point fire button 5 is made of a transparent resin, and at the end on the first internal passage 11a side, projecting pieces 71a extending toward the first internal passage 11a face each other. Two places are provided. Then, each of the protruding pieces 71a is slidably engaged in each of the concave portions 72b, and the knob member 71 and the dial member 72 are assembled. In addition, a reflection member 73 substantially matching the inner shape of the knob member 71 is mounted inside the knob member 71. A reflective layer is formed on the outer surface of the reflective member 73 by coating with aluminum. The reflecting member 73 is also provided with a flange portion 73a that simultaneously contacts a step portion 5a formed on the outer peripheral surface of the point fire button 5 and a step portion 71b formed on the inner peripheral surface of the knob member 71. The reflecting member 73 is urged forward by a spring 74 compressed between the dial member 73a and the dial portion 72.
[0032]
As a result, the knob member 71 is pressed against the point fire extinguishing button 5 by the urging force of the spring 74, and when the point fire extinguishing button 5 is pressed, the knob member 71 moves rearward accordingly, and in the valve open position, the knob When the member 71 is rotated, the dial member 72 is rotated via the concave portion 72b engaged with the protruding piece 71a. On the other hand, in the closed position of the fire extinguishing button 5, the heating power adjustment dial 7 can move alone in a direction in which the outer peripheral surface of the fire extinguishing button 5 is exposed. In this case, if the knob member 71 is moved at the valve closing position, the outer peripheral surface of the fire extinguishing button 5 is exposed, and dust adhering thereto can be cleaned. In addition, even if the user presses the firepower adjustment dial 7 while holding it, the fire extinguishing button 5 does not move, so that the forced rotation means described later is not damaged. Further, by providing the reflecting member 73, even if dirt or dirt adheres to the outer peripheral surface of the point fire button 5, it may be hidden by the reflecting member 73.
[0033]
Referring to FIG. 7, a light source E such as an LED that irradiates light from above the transparent knob member 71 toward the reflecting member 73 is provided inside the front panel 24, and the valve opening position of the point fire extinguishing button 5 is provided. Thus, the light is emitted from the light source so that the knob member 71 shines. Thereby, the operating condition of the gas stove 2 can be visually confirmed. In this case, the front edge of the heating power adjusting dial 7 is a chamfered portion C, and when light is emitted from the light source E to the dial member 71, the chamfered portion C shines in a ring shape. A convex portion 73b extending in the longitudinal direction is formed on the surface of the reflecting member 73 (see FIG. 6). The convex portion 73b is accommodated in a longitudinal accommodating portion 71c provided on the knob 71, and the front panel The index of the thermal power of the gas burner 23 is constituted by the coincidence between the thermal power position of the gas burner indicated by 24 and the projection 73b. In addition, since the indicator does not emit light even when the light from the light source E is irradiated, the indicator has an effect of being raised with respect to the glowing environment, and the cook can easily recognize the coincidence between the heating position and the indicator.
[0034]
8 to 12, a cam groove 72c is formed in the inner peripheral surface on the rear side of the dial member 72, and the outer peripheral surface of the pressing rod 51 that moves in the dial member 72 in the front-rear direction is provided with a cam. Two projections 51b, which are paired with the groove 72c, are provided (see FIG. 6), and the cam groove 72c and the projection 51b constitute a forced rotation unit. In this case, the height of the wall surface of the cam groove 72c is formed so as to decrease from one side to the other as the point fire button 5 is pressed. When the gas extinguishing button 5 is pushed in from the valve closing position to reach the valve opening position in order to ignite the gas burner 23, the projection 51b engages with the cam groove 72c, and the projection 51b becomes the prime mover. By rotating the dial member 72 in which the cam groove 72c as a follower is formed, when the point fire extinguishing button 5 reaches the ignition position, the fuel gas is supplied to the gas burner 23 at a flow rate that ensures ignition. Rotated. In the present embodiment, the heating power adjustment dial 7 is forcibly rotated to the medium fire position by the pushing operation of the point fire extinguishing button 5 by the forced rotation means 51b and the cam groove 72c.
[0035]
In this case, since the heating power adjustment dial 7 is rotated using the pushing operation of the point fire extinguishing button 5, it is not necessary to increase the urging force of the spring 17 contracted between the pressing rod 51 and the first portion 11a, for example. The structure of the gas control device 1 can be simplified. In addition, since the distance between the valve opening position where the moving distance of the fire extinguishing button 5 is set to be long and the ignition position for opening the electromagnetic safety valve 3 is diverted to the forced rotation of the heating power adjustment dial 7, The required movement distance is shorter than the movement distance of the point extinguishing button 5 between the valve closing position and the valve opening position, and the distance for forcibly rotating the heating power adjustment dial 7 is added. Since the moving distance in the front-rear direction can be shortened, the operation feeling is good and the usability is good.
[0036]
In the ignition position, the gas burner 23 is ignited by operating the discharge unit. After that, when the pushing of the point fire extinguishing button 5 is released, it is guided by the heart cam mechanism 52 and slightly returned by the urging force of the spring 17, and the point extinguishing button 5 reaches the valve opening position. At the valve opening position, the engagement between the projection piece 51b and the cam groove 72c is released, and the dial member 72 becomes rotatable clockwise or counterclockwise. In this case, when the heating power adjustment dial 7 is rotated clockwise, the gas flow rate is reduced, and when the heating power adjustment dial 7 is rotated counterclockwise, the rotating body 61 is rotated so that the gas flow rate increases. As a result, the operability of the heating power adjustment dial 7 at the valve opening position is not impaired, and the rotation operation feeling of the cook is not adversely affected. Further, since the engagement between the projection 51b and the cam groove 72c is released by the return of the point fire button 5 when the push of the point fire button 5 is released, the forced rotation means 51b is turned by the heating power adjusting dial 7 at the valve opening position. It is not necessary to separately provide a mechanism for preventing interference with the cam groove 72c, and it is not necessary to increase the number of parts.
[0037]
In order to limit the rotation range of the heating power adjustment dial 7, two convex portions 72d opposing each other are formed at a position where the cam groove 72c of the dial member 72 is formed. When the heating power adjusting dial 7 is rotated and rotated in the counterclockwise direction until each protruding piece 51b abuts on the convex portion 72d, the second, third and fourth long grooves 62b, 62c and 62d become the second and third long grooves. The rotating body 61 is arranged so that the amount of gas to the gas outlet 16 is maximized in accordance with the third and fourth communication paths 15b, 15c, 15d. On the other hand, if the projection 51d is rotated clockwise until the projections 51b abut against the projection 72d, the first long groove 62a coincides only with the first communication path 15a, and the amount of gas to the gas outlet 16 is minimized. Like that. Thus, in the valve opening position, the heating power adjustment dial 7 increases the heating power of the gas burner 23 by minimizing the gas flow to the gas outlet 16 to minimize the heating power of the gas burner 23 and the gas flow to the maximum. It is rotatable only within a heating power adjustment range between the above-mentioned high heating power. Accordingly, it is not necessary to separately provide a stopper or the like for limiting the rotation range of the heating power adjustment dial 7, and the number of parts can be reduced and the cost can be reduced.
[0038]
As shown in FIG. 13, at the valve closing position of the point fire extinguishing button 5, the protrusion 51 b is located on the front side of the position where the cam groove 72 c of the dial member 72 is formed. In this case, the heating power adjustment dial 7 can be rotated counterclockwise beyond the heating power adjustment range at the valve closing position, and at this position, the protruding piece 51b faces the projection 72d. As a result, even when the point fire extinguishing button 5 is pressed, the projecting piece 51b abuts on the front side of the front panel 24 of the projection 72b, and the lock position where the point fire extinguishing button 5 cannot move from the valve closing position to the ignition position is established. Formed and child locked. In this case, a protrusion E is provided on the outer peripheral surface of the dial member 72 (see FIG. 8), and when the protrusion E comes into contact with a stopper (not shown) provided on the first portion 11a, the lock position is reached.
[0039]
Referring to FIGS. 6 and 14, the first, second and third concave portions 72 e, 72 f, 72 a, and 72 b are provided on the inner peripheral surface on the front side of dial member 72 at predetermined intervals in the same circumferential direction. 72 g are formed. At the rear end of the point fire button 5, a radial hole 5b is formed. In this hole 5b, a cylindrical click member C is urged toward the inner peripheral surface of the dial member 72 by a spring C1. It is stored in a state where it is made to be. Then, when the heating power adjustment dial 7 is rotated to reach a predetermined position at the valve opening position, the click members 52 are fitted into the concave portions 72e, 72f, and 72g to generate a click.
[0040]
Next, the operation of the gas control device 1 of the present invention will be described. When the point fire extinguishing button 5 is pushed from the valve closing position shown in FIG. 2, the operating rod 4 is pushed rearward through the pushing rod 51 to open the main valve, and when the valve reaches the valve opening position shown in FIG. 3. Before the protrusion 51b and the cam groove 72c engage with each other and reach the ignition position where the valve body 32 is pushed to the suction side, the heating power adjustment dial 7 is rotated to the medium heat position. In this case, the rotating body 61 is rotated via the gear G. At this position, the first, second, and third long grooves 62a, 62b, 62c are in the first, second, and third communication paths 15a, 15b and 15c, respectively, and the fuel gas flows at the gas outflow portion 16 at a gas flow rate with the thermal power of the gas burner 23 as the middle (see FIG. 5). The click member C is fitted in the second recess 72f (see FIG. 14).
[0041]
When the ignition position is reached, the ignition operation of the gas burner 23 is performed by the discharge unit. When a flame detection element (not shown) provided near the gas burner 23 detects the flame of the gas burner 23, the signal from the control unit excites the electromagnetic valve 3 to hold the valve open. When it is confirmed that the gas burner 23 is ignited and the pressing of the fire extinguishing button 5 is released, the fire extinguishing button 5 is guided by the heart cam mechanism 52 to reach the valve opening position shown in FIG.
[0042]
When the click member C is fitted in the third concave portion 72g in order to increase the heating power of the gas burner 23 and is rotated counterclockwise from the medium heat position, the respective projection pieces 51b abut on the convex portion 72d. In this case, the second, third and fourth long grooves 62b, 62c and 62d respectively correspond to the second, third and fourth communication passages 15b, 15c and 15d, and the thermal power of the gas burner 23 is increased. The fuel gas having the gas flow rate flows to the gas outlet 16 (see FIG. 15).
[0043]
On the other hand, in order to reduce the heating power of the gas burner 23 from medium heat, the heating power adjustment dial 7 is rotated clockwise, and when the click member C is fitted into the first recess 72e, the first and second long grooves 62a, 62b Correspond to the first and second communication passages 15a and 15b, respectively, and the fuel gas having a gas flow rate that weakens the thermal power of the gas burner 23 flows to the gas outlet 16 (see FIG. 16). Next, when the heating power adjustment dial 7 is rotated clockwise until each of the projection pieces 51b abuts on the projection 72d, the first long groove 62a coincides only with the first communication passage 15a, and the heating power of the gas burner 23 is reduced. The fuel gas having the gas flow rate flows to the gas outlet 16 (see FIG. 17).
[0044]
When the gas burner 23 is extinguished, when the point fire extinguishing button 5 is pushed backward from the valve opening position, the heart cam mechanism 52 is reset, and the point extinguishing button 5 receives the urging force of the spring 17 to close the valve shown in FIG. Retreat to position. In this case, the operation rod 4 from which the pressing of the pressing rod 51 is released moves forward by receiving the urging force of the spring 34, and closes the main valve. When the main valve is closed, the supply of fuel gas to the gas burner 23 is stopped and the fire is extinguished. When the control unit recognizes that the flame has been extinguished by the flame detecting element, the electromagnetic safety valve 3 is closed.
[0045]
