【発明の属する技術分野】
本発明はカートリッジ式の燃料供給タンクを着脱自在に備えた石油燃焼暖房機等の石油燃焼機に関するものである。
【０００２】
【従来の技術】
従来の石油燃焼暖房機等の石油燃焼機について、図６〜図９を用いて説明する。図６に示すように、長方形状の燃焼機器本体１は、前面下部のルーバ２の部分より、石油を燃焼させて空気を温めた温風を吹出して部屋を暖房するものである。そして、燃焼機器本体１は、石油を供給するカートリッジ式の持ち運び可能な燃料供給タンク３を燃焼機器本体１の上方より燃焼機器本体１の左隅上面に開口４ａしたタンク収納部４に着脱自在に設置している。
【０００３】
すなわち、燃料供給タンク３は、石油を補給する時には開閉扉５を開き、取っ手６を持ってタンク収納部４より、燃料供給タンク３の長さ以上に持ち上げて取りだし、また石油を補給した燃料供給タンク３をタンク収納部４に設置する時には、取っ手６を持って持ち運んできた燃料供給タンク３を、燃焼機器本体１の高さ以上に持ち上げ、かつタンク収納部４の真上に横移動させて開口４ａに合わせながらタンク収納部４内に下ろして設置するものである。
【０００４】
このように取り扱う燃料供給タンク３は、使い勝手上から使用中における燃料補給の回数を少なくして手間を省くことと、燃焼機器本体１における設置スペースを小さくするために図９に示すように縦長の直方体に形成され、上面に取っ手６を、下面中央に石油を供給する給油口７を設け、この給油口７に弁機構８を有する給油キャップ９を取り付け、給油口７の端面７ａを給油キャップ９に設けたシール面８ｃでシールすることにより、弁機構８を介して給油口７の開放状態と閉塞状態を保つような構成としている。
【０００５】
そして、燃料供給タンク３は、燃焼機器本体１のタンク収納部４に設置する時は、図７に示すように給油口７を下向きにして燃焼機器本体１内の下部に設けてある油受け容器１０の受け部１０ａに嵌合することで、燃料供給タンク３の全体の重量を受けて受け部１０ａ内に設けた固定の弁押し上げピン１１により弁体８ｂが内蔵バネ８ａおよび石油の圧力に抗して押し上げられ、弁機構８の吐出口１２が強制的に開放され油受け容器１０に石油が供給され、油受け容器１０内の油面が弁機構８の吐出口１２に達すると燃料供給タンク３からの石油の供給が停止する。
【０００６】
従って、油受け容器１０内の燃料が消費され油面が低下する毎に、燃料供給タンク３からの燃料の供給が開始される。この繰り返しにより燃料供給タンク３から油受け容器１０への燃料の供給が自動的に行われる。
【０００７】
次に、燃料供給タンク３の燃料が消費され補給が必要となった場合は、燃焼機器本体１のタンク収納部４から燃料供給タンク３を取り出すことで、弁押し上げピン１１が弁機構８から離れ、弁機構８は内蔵バネ８ａにより弁体８ｂを吐出口１２に密着させることで閉塞状態となり、燃料供給タンク３からの燃料の流出を防止する。この状態で燃料供給タンク３を反転させ、給油キャップ９を上向きにして給油キャップ９を緩め、給油口７から取り外す。そして、給油口７から石油を補給したのち再び、給油キャップ９を螺合させて給油口７に取り付け、燃焼機器本体１に逆転装着することで、油受け容器１０への供給が開始されるものである。
【０００８】
つまり、従来の燃料供給タンク３の着脱操作は、燃料供給タンク３を燃焼機器本体１の上方まで持ち上げ、タンク収納部４の上方から着脱するようになっていた。
【０００９】
上記したように従来の構成においては、燃料供給タンク３を燃焼機器本体１のタンク収納部４に着脱する際、空の場合は負担が少ないが、燃料を補給して満量となった燃料供給タンク３を燃焼機器本体１のタンク収納部４に装着する時は、重量が増大しているため、燃焼機器本体１の上方まで持ち上げ、かつタンク収納部４の真上に横移動させて開口４ａに合わせながらタンク収納部４内に下ろして設置する必要があり、使用者の最も大きな負担となっている。
【００１０】
特に近年、燃料供給タンク３は使い勝手上から給油回数を減らして給油の手間を省くため、どんどん大容量化の傾向にあり、９リットルを超えるものまで出てきている。例えば、９リットルの燃料供給タンクであれば、燃料供給タンク自身の重量と燃料の重量を合わせると１０ｋｇを超えるような重量となる。
【００１１】
また、燃焼機器本体１も設置の省スペース化の観点から、そのフォルムも横長のものより縦長のものが増えてきており、タンク収納部４に燃料供給タンク３を燃焼機器本体１より上方へ持ち上げて装着する作業が益々困難となっている。
【００１２】
また、燃料供給タンク３の装着作業は、設置者の姿勢的にも燃料供給タンク３をタンク収納部４の上方真上へ、体から離して持ち上げなければならなく負担が大きい。特に、上背の低い人や力の弱い人、例えばお年寄りや女性等は負担が極めて大きくなり、給油の度毎に燃料供給タンク３の着脱作業が煩わしいものであった。
【００１３】
さらに、燃料供給タンク３の容量が大型化する中にあって、燃料供給タンク３に燃料を満量まで入れると、燃料供給タンク３を燃焼機器本体１の上方まで持ち上げられない、あるいは負担が大きくなり過ぎる等の理由で、燃料を燃料供給タンク３の途中まで入れて使うという使用者もあり、その結果、給油作業を頻繁に行わなければならないことになり、タンク容量を大型化し給油回数の手間を省くという製造者の意図に反した使用方法が行われている。
【００１４】
さらに、タンク収納部４に収納されて油受け容器１０の受け口１０ａに給油口７を嵌合している燃料供給タンク３は、図７に示すようにタンク収納部４内に自立している状態なので、何らかの理由で燃焼機器本体１に衝撃や振動が加わると自立が不安定になる恐れがあった。
【００１５】
【発明が解決しようとする課題】
上記従来の技術の問題点に鑑み、本発明が解決しようとする課題は、燃料補給時における燃料供給タンクの燃焼機器本体への着脱作業の負担を軽減し、かつ燃料供給タンクの収納を確実にして使い勝手と安全性の向上を図った石油燃焼機を提供することを目的とするものである。
【００１６】
【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は、油受け容器の上部に位置して燃焼機器本体内に設けたタンク収納部を、前記燃焼機器本体の横方向から燃料供給タンクを着脱できるように側面を開放し、かつタンク収納部に油受け容器に装着した前記燃料供給タンクを保持するタンク保持手段を設けた石油燃焼機としている。
【００１７】
上記手段によれば、従来の技術のように燃料供給タンクを燃焼機器本体の上方まで持ち上げずに使用者は着脱が容易に行うことができ、特に燃料が満量で重量物となる燃料供給タンクを、使用者が無理な姿勢で持ち上げなくてもよくなり、着脱作業の負担が大幅に軽減でき、大幅に使い勝手を向上できる。
【００１８】
また、油受け容器の上部およびタンク収納部内も燃焼機器本体の横方向から容易に掃除することができるとともに、タンク収納部に燃料供給タンクが保持され、開閉扉を開けた際、不意に倒れてくるのを防止できる。
【００１９】
【発明の実施の形態】
上記した本発明の目的は、各請求項に記載した構成を実施の形態とすることにより達成できるので、以下には各請求項に記載の構成にその構成による作用効果を併記し併せて請求項記載の構成のうち説明を必要とする特定用語については詳細な説明を加えて実施の形態とする。
【００２０】
請求項１記載に係る発明は、燃焼機器本体と、前記燃焼機器本体に設け、燃料を一時的に貯留する油受け容器と、前記油受け容器に着脱自在に設け、燃料を前記油受け容器に供給する持ち運び可能な燃料供給タンクと、前記油受け容器の上部に位置して前記燃焼機器本体内に設け、前記燃料供給タンクを収納するタンク収納部およびタンク収納部を開閉する開閉扉とを備え、前記タンク収納部は前記燃焼機器本体の横方向から前記燃料供給タンクを着脱できるように少なくとも側面を開放し、かつ前記油受け容器に装着した前記燃料供給タンクを保持するタンク保持手段を、前記開閉扉で覆われる面以外のタンク収納部の面に設けた石油燃焼機である。
【００２１】
上記実施の形態によれば、タンク収納部には燃料供給タンクを燃焼機器本体の横方向から着脱できるようになり、従来の技術のように燃料供給タンクを燃焼機器本体の上方まで持ち上げずに使用者は着脱を容易に行うことができ、使い勝手を向上できる。
【００２２】
また特に、燃料が満量で重量物となる燃料供給タンクを、使用者は無理な姿勢で燃焼機器本体の上方まで持ち上げなくてもよくなり、着脱作業の負担が大幅に軽減される。さらに、タンク収納部内はもちろん、油受け容器の上部も燃焼機器本体の横方向から臨めるので、タンク収納部および油受け容器の上部を容易に掃除することができるとともに、シーズン終了後の機器収納作業時において、油受け容器から残った燃料を抜き取る際も、従来の技術における燃焼機器本体の上面に臨むタンク収納部の開口からホースなどを差し込んでする必要ががなく、油漏れ等の心配もなく、燃焼機器本体の横方向から簡単に行うことができる。
【００２３】
さらに、油受け容器に燃料供給タンクを装着した時に、燃料供給タンクはタンク収納部の開閉扉で覆われる面以外の面に設けたタンク保持手段により保持されているので、例えば開閉方向を横方向に回動させる開閉扉の構成にしても燃料供給タンクが開閉扉側に倒れる心配がなくなり、不用意に開閉扉が開いて燃料供給タンクがタンク収納部から離脱するのを防止できる、安全で給油作業が簡単なタンク着脱構成を実現することができる。
【００２４】
請求項２記載に係る発明は、請求項１記載の石油燃焼機にあって、タンク保持手段を、磁石で形成したものである。
【００２５】
上記実施の形態によれば、タンク収納部に収納した燃料供給タンクは開閉扉で覆われるタンク収納部の面以外の面に設けたタンク保持手段である磁石により吸着され、振動や衝撃等が燃焼機器本体に加わっても燃料供給タンクが開閉扉側に倒れる心配がなくなり、不用意に開閉扉が開いて燃料供給タンクがタンク収納部から離脱するのを防止できる。
【００２６】
請求項３記載に係る発明は、請求項１または請求項２記載の石油燃焼機にあって、油受け容器に装着した燃料供給タンクを保持するタンク保持手段は、タンク収納部を開閉する開閉扉側と異なる側へ傾かせて燃料供給タンクを保持する構成としたものである。
【００２７】
上記実施の形態によれば、タンク収納部に収納して油受け容器に装着した燃料供給タンクは、タンク保持手段によりタンク収納部の開閉扉側と異なる側に傾いて保持され、振動や衝撃等が燃焼機器本体に加わっても燃料供給タンクが開閉扉側に倒れてくる心配が確実になくなり、不用意に開閉扉が開いて燃料供給タンクがタンク収納部から離脱するのを防止できる。
【００２８】
【実施例】
以下本発明の石油燃焼機である石油燃焼暖房機の一実施例について、図面を用いて説明する。
【００２９】
（実施例１）
図１は本発明の実施例１における石油燃焼暖房機の燃料供給タンク部分の着脱構成を示す斜視図で、図２は同燃料供給タンクの設置状態を示す要部半裁の断面図で、図３は同燃料供給タンクの正面図で、図４は同燃料供給タンクの給油キャップの断面図である。
【００３０】
図において、長方形状の燃焼機器本体２１は、前面下部のルーバ２２の部分より、燃料である石油を燃焼させて空気を温めた温風を吹出して部屋を暖房するものである。そして、燃焼機器本体２１は、石油を供給するカートリッジ式の持ち運び可能な燃料供給タンク２３を燃焼機器本体２１の右隅部分の横方向（水平方向を含む）より、燃焼機器本体２１の下部に設けた燃料を一時的に貯留する油受け容器２４の上部に位置したタンク収納部２５に矢印で示すように出し入れ自在に、かつ油受け容器２４に着脱自在に設置している。
【００３１】
すなわち、タンク収納部２５は燃焼機器本体２１内の右隅部分に縦方向に設け、燃焼機器本体２１の上面と右側面および背面の３面に臨む開放した開口を有し、この３面の開口を同時に開閉できる開閉扉２６を燃焼機器本体２１の背面板にヒンジ（図示せず）を介して横方向へ矢印で示すように回動自在に設けている。また、タンク収納部２５は油受け容器２４に装着した燃料供給タンク２３の上面と開閉扉２６の上面との間に所定の間隙ｈを設けて、燃焼機器本体２１が何らかの原因で転倒した時に、燃料供給タンク２３が油受け容器２４から間隙ｈの分だけ移動（ずれる）することで、燃料供給タンク２３の弁機構（後述する）が作動して閉塞できるように構成している。
【００３２】
従って、燃料供給タンク２３は、石油を補給する時には開閉扉２６を燃焼機器本体２１の背面側へ回動して開き、上面に設けた取っ手２７を持ってタンク収納部２５より、間隙ｈだけ持ち上げて弁機構が閉じてから横方向へ取りだし、また石油を補給した燃料供給タンク２３をタンク収納部２５に設置する時には、取っ手２７を持って持ち運んできた燃料供給タンク２３を、開いているタンク収納部２５の横方向から持ち運んでタンク収納部２５の真上に横移動させて少なくとも間隙ｈだけタンク収納部２５内に下ろして油受け容器２４上に設置するものである。
【００３３】
このように取り扱う燃料供給タンク２３は、使い勝手上から使用中における燃料補給の回数を少なくして手間を省くことと、燃焼機器本体２１における設置スペースを小さくするために図３に示すように縦長の略直方体に形成され、上面に取っ手２７を、下面中央に石油を供給する給油口２８を設けている。２８ａは給油口２８の外周部に設けたネジ部で、２９は燃料供給タンク２３の燃料の量を確認する油量窓である。
【００３４】
３０は給油口２８のネジ部２８ａに着脱自在に螺合した給油キャップで、給油キャップ３０の内面に設けたネジ部３０ａと給油口２８のネジ部２８ａとが噛み合うようになっている。３１は給油キャップ３０内に一体化して設けた複数個の貫通孔３１ａを有する弁筒で、内部に弁機構３２を設けている。弁機構３２は給油キャップ３０と弁筒３１間に内装してあり、弁体３４と弁座３５およびバネ３６で構成し、給油キャップ３０の吐出口３３の開閉を行う。
【００３５】
３７は油受け容器２４の上面に取りつけた筒状の受け口で、燃料供給タンク２３の給油キャップ３０が嵌合し、かつ弁機構３２を開閉する弁押し上げピン３８が底部中央に突起してある。３９は油受け容器２４の受け口３７に給油キャップ３０を嵌合してタンク収納部２５内に自立した燃料供給タンク２３を保持するタンク保持手段で、開閉扉２６で覆われる面以外のタンク収納部２５の面に設けた永久磁石等の磁石で形成し、開閉扉２６側と反対側における燃料供給タンク２３の外面を吸着して自立状態に保持するものである。
【００３６】
上記実施例において、その動作を説明すると、まず給油キャップ３０を下向きにして燃料供給タンク２３を油受け容器２４の受け口３７に装着すると、弁押し上げピン３８が弁体３４をバネ３６に抗して押し上げ、弁座３５による給油キャップ３０の吐出口３３の閉塞状態が解除される。これにより、燃料供給タンク２３の燃料は受け口３７を介して油受け容器２４内に供給され、給油キャップ３０の吐出口３３の油面高さまで蓄えられる。
【００３７】
そして、燃焼機器本体２１のバーナ（図示せず）で消費され油受け容器２４内の油面が低下すると、吐出口３３より燃料供給タンク２３内に空気が入り、この空気の置換作用で燃料供給タンク２３の燃料は油受け容器２４内に供給される。この繰り返しにより油受け容器２４内の油面は一定油面を保持する。燃料供給タンク２３内の燃料が給油キャップ３０の端部、つまり吐出口３３まで減少してくると、弁筒３１の外周部に設けた複数の貫通孔３１ａより燃料の供給は継続され、燃料供給タンク２３内の燃料はほとんど使いきることになる。
【００３８】
次に、燃料供給タンク２３の燃料が空になると、開閉扉２６を開きタンク収納部２５から燃料供給タンク２３を取りだし給油キャップ３０を受け口３７から取り外す。この時、弁機構３２は弁押し上げピン３８で弁体３４を押し上げていた動作が解除されるため、弁体３４はバネ３６により元の状態に戻り、弁座３５を介して吐出口３３を閉塞状態に保つ。そして、取り出した燃料供給タンク２３を給油場所まで運び、給油キャップ３０を給油口２８から取り外してサイフォンポンプなどで給油口２８より給油を行う。
【００３９】
すなわち、タンク収納部２５には油受け容器２４上部近傍から横方向へ開閉する開閉扉２６を配設してあるので、開閉扉２６を横方向に回動させると、燃焼機器本体２１の上面、右側面、背面であるタンク収納部２５の３面が開放状態となり、取っ手２７を持って空の燃料供給タンク２３を少し持ち上げ（少なくとも間隙ｈ以上）て油受け容器２４の受け口３７から嵌合を外して横方向へ移動させタンク収納部２５より取り出すことができる。
【００４０】
また、燃料を補給して満量にした燃料供給タンク２３を油受け容器２４に装着する時は、取っ手２７を持って持ち運んできた燃料供給タンク２３を、開いているタンク収納部２５の横方向から持ち運んでタンク収納部２５の真上に横移動させて少なくとも間隙ｈだけタンク収納部２５内に下ろして油受け容器２４の受け口３７に給油キャップ３０を嵌合して設置し、最後に開閉扉２６を横方向に回動してタンク収納部２５をカバーする。そして、タンク収納部２５に収納された燃料供給タンク２３はタンク保持手段３９に吸着されて自立状態に保持される。
【００４１】
従って、従来のように取っ手２７を持って持ち運んできた燃料供給タンク２３を、燃焼機器本体２１の上方まで持ち上げて装着する必要がなく、燃料が満量状態で重い燃料供給タンクでも、使用者は容易にタンク収納部２５に着脱操作を行うことができ、使い勝手を向上できる。
【００４２】
さらに、タンク収納部２５に油受け容器２４の上部近傍から開閉する開閉扉２６は、タンク収納部２５の右側面と背面を開放するため、油受け容器２４が間近にあって斜め上方に臨むことができ、油やほこりなどで汚れた油受け容器２４の上面を容易に掃除することができ、また、シーズン終了後の燃焼機器本体２１の収納作業における油受け容器２４から残った燃料の抜き取り作業も、開放したタンク収納部２５の右側面と背面から受け口３７を通じて容易に行うことができる。
【００４３】
さらに、油受け容器２４に燃料供給タンク２３を装着した時に、燃料供給タンク２３の上面と燃焼機器本体２１のタンク収納部２５の開口上面である開閉扉２６の上面との間に、所定の間隙ｈを有する構成としてあるので、燃焼機器本体２１が何らかの原因で転倒したときに、油受け容器２４から燃料供給タンク２３が間隙ｈの分だけ移動し、弁押し上げピン３８よりずれ弁機構３２が閉塞されるため、燃料供給タンク２３内の燃料が流出し続けることがなく、安全性を向上できる。
【００４４】
さらに、タンク収納部２５には開閉扉２６側と異なる側のタンク収納部２５の面にタンク保持手段２９を設け、このタンク保持手段２９の吸着作用により油受け容器２４の受け口３７に装着して自立した燃料供給タンク２３を保持しているので、振動や衝撃等が燃焼機器本体２１に加わっても燃料供給タンク２３が開閉扉２６側に倒れてくる心配がなくなり、開閉扉２６の開閉方向が矢印で示す横方向に回動するように構成してあって不用意に開閉扉２６が開いても燃料供給タンク２３がタンク収納部２６から離脱することなく、安全性が確保される。
【００４５】
（実施例２）
図５は本発明の実施例２における石油燃焼暖房機の燃料供給タンク部分の着脱構成を示す斜視図である。本実施例は、実施例１の発明で述べた部分と同じ構成並びに作用効果を奏するところには同一符号を付して詳細な説明を省略し、異なるところを中心に説明する。
【００４６】
図５において、油受け容器２４に燃料供給タンク２３を装着した時に、燃料供給タンク２３が燃焼機器本体２１のタンク収納部２５の開閉扉２６側と異なる側の面に傾いて保持されるように開閉扉２６側に位置する油受け容器２４の上面に突起部４０を配設してある。従って、油受け容器２４の筒状の受け口４１も、前記突起部４０により油受け容器２４に装着した燃料供給タンク２３が燃焼機器本体２１のタンク収納部２５の開閉扉２６側と異なる側の面に傾いて保持されるように、油受け容器２４の上面に傾いて取付けてある。
【００４７】
上記実施例は、実施例１のタンク保持手段３９の構成を、他の構成で実現したものである。すなわち、油受け容器２４の受け口４１に給油キャップ３０を嵌合して燃料供給タンク２３を装着した時に、開閉扉２６側に位置する油受け容器２４の上面の突起部４０に燃料供給タンク２３の給油口２８の右底が乗り上げ、かつ傾いている受け口４１に給油キャップ３０が嵌合して図５に示すように燃料供給タンク２３は、タンク収納部２５の開閉扉２６側と異なる側に傾いて一部がタンク収納部２５の面に当たり保持される。
【００４８】
従って、開閉扉２６の開閉方向を横方向にしても、何らかの理由で振動や衝撃が燃焼機器本体２１に加わっても燃料供給タンク２３が開閉扉２６側に倒れる心配がなくなり、不用意に開閉扉２６が開いて燃料供給タンク２３がタンク収納部２５から離脱することもなく、安全性を確保できる。
【００４９】
なお、上記実施例１ではタンク保持手段３９として磁石を使用したが、これは他の実施例２のような構成でもよく、また、燃料供給タンクの固定手段と傾斜手段を組み合わせてもよく、本発明の目的・効果を達成するものであれば、実施例の構成に限られることなく、どのように構成してもよいものである。
【００５０】
また、上記各実施例ではタンク収納部２５を燃焼機器本体２１の上面と右側面および背面の３面において開口させたが、燃焼機器本体２１の上面を除く一つの側面、または燃焼機器本体２１の上面と左右いずれかの側面または背面または前面のいずれか２面が開口してあれば、本実施例と同様の作用効果を期待できるものであり、またタンク収納部２５の形成する位置も燃焼機器本体２１の左右いずれの角部分、その他の場所であっても良い。
【００５１】
さらにタンク収納部２５が前記した２面の開口である場合、開閉扉２６も開放した２面、または開放した一つの側面をカバーする横方向の回動とするものである。
【００５２】
【発明の効果】
以上のように本発明によれば、燃焼機器本体の上方まで持ち上げずに燃料供給タンクを油受け容器に燃焼機器本体の横方向から着脱でき、使い勝手を向上させることができるとともに、燃料供給タンクを安定してタンク収納部に保持できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an oil-fired machine such as an oil-fired heater provided with a cartridge-type fuel supply tank detachably.
[0002]
[Prior art]
A conventional oil-fired machine such as an oil-fired heater will be described with reference to FIGS. As shown in FIG. 6, the combustion equipment main body 1 in a rectangular shape heats a room by blowing hot air heated from air by burning oil from a louver 2 at a lower front portion. The main body 1 of the combustion equipment is configured such that a portable fuel supply tank 3 of a cartridge type for supplying petroleum is detachably installed in a tank storage part 4 having an opening 4a on the upper left corner of the main body 1 of the combustion equipment from above the main body 1 of the combustion equipment. are doing.
[0003]
That is, the fuel supply tank 3 is opened by opening and closing the door 5 when replenishing oil, holding the handle 6, lifting the fuel supply tank 3 from the tank storage unit 4 to the length of the fuel supply tank 3, and taking out the fuel supply tank. When the tank 3 is installed in the tank housing 4, the fuel supply tank 3 carried with the handle 6 is lifted above the height of the combustion device main body 1 and moved laterally right above the tank housing 4. It is set down in the tank housing 4 while being aligned with the opening 4a.
[0004]
As shown in FIG. 9, the fuel supply tank 3 to be handled in this manner is vertically long as shown in FIG. It is formed in a rectangular parallelepiped, and a handle 6 is provided on the upper surface, an oil supply port 7 for supplying oil at the center of the lower surface, an oil supply cap 9 having a valve mechanism 8 is attached to the oil supply port 7, and an end face 7a of the oil supply port 7 is connected to the oil supply cap 9 Is sealed by a sealing surface 8c provided in the oil supply port 7 to maintain the open state and the closed state of the oil supply port 7 via the valve mechanism 8.
[0005]
When the fuel supply tank 3 is installed in the tank storage section 4 of the combustion equipment main body 1, an oil receiving container provided at a lower portion inside the combustion equipment main body 1 with the fuel supply port 7 facing downward as shown in FIG. 10, the valve body 8b receives the entire weight of the fuel supply tank 3 and the fixed valve push-up pin 11 provided in the receiving portion 10a causes the valve body 8b to withstand the pressure of the built-in spring 8a and the oil. When the oil outlet of the valve mechanism 8 is forcibly opened and oil is supplied to the oil receiving container 10 and the oil level in the oil receiving container 10 reaches the outlet 12 of the valve mechanism 8, the fuel supply tank is opened. The supply of oil from 3 stops.
[0006]
Therefore, the supply of fuel from the fuel supply tank 3 is started each time the fuel in the oil receiving container 10 is consumed and the oil level is lowered. By this repetition, the supply of fuel from the fuel supply tank 3 to the oil receiving container 10 is automatically performed.
[0007]
Next, when the fuel in the fuel supply tank 3 is consumed and the fuel needs to be replenished, the fuel supply tank 3 is taken out from the tank storage part 4 of the combustion equipment main body 1 so that the valve push-up pin 11 is separated from the valve mechanism 8. The valve mechanism 8 is closed by bringing the valve body 8b into close contact with the discharge port 12 by the built-in spring 8a, thereby preventing the fuel from flowing out of the fuel supply tank 3. In this state, the fuel supply tank 3 is inverted, the fuel supply cap 9 is turned upward, the fuel supply cap 9 is loosened, and the fuel supply tank 9 is removed from the fuel supply port 7. Then, after replenishing oil from the oil supply port 7, the oil supply cap 9 is screwed again, attached to the oil supply port 7, and mounted on the combustion equipment main body 1 in reverse, so that supply to the oil receiving container 10 is started. It is.
[0008]
In other words, in the conventional operation of attaching and detaching the fuel supply tank 3, the fuel supply tank 3 is lifted up to above the combustion device main body 1, and is attached and detached from above the tank storage section 4.
[0009]
As described above, in the conventional configuration, when the fuel supply tank 3 is attached to and detached from the tank storage section 4 of the combustion equipment main body 1, the load is small when empty, but the fuel supply tank becomes full by replenishing the fuel. When the tank 3 is mounted in the tank storage section 4 of the combustion equipment main body 1, since the weight is increased, the tank 3 is lifted to above the combustion equipment main body 1 and moved laterally right above the tank storage section 4 to open the opening 4 a. It is necessary to set down the tank inside the tank storage unit 4 while adjusting to the above, which is the biggest burden on the user.
[0010]
In particular, in recent years, the fuel supply tank 3 has been tending to increase in capacity, in order to reduce the number of times of refueling from the convenience of use and to save the trouble of refueling. For example, if the fuel supply tank is 9 liters, the weight of the fuel supply tank itself and the weight of the fuel together exceed 10 kg.
[0011]
Also, from the viewpoint of space saving of the installation of the combustion equipment main body 1, the form of the combustion equipment main body 1 is longer than the horizontal one, and the fuel supply tank 3 is lifted in the tank storage part 4 above the combustion equipment main body 1. It is becoming more and more difficult to attach and attach.
[0012]
In addition, the mounting work of the fuel supply tank 3 requires lifting the fuel supply tank 3 to a position directly above the tank housing part 4 and away from the body in terms of the posture of the installer. Particularly, a short person or a weak person, such as an elderly person or a woman, is extremely burdened, and the work of attaching and detaching the fuel supply tank 3 every time refueling is troublesome.
[0013]
