【発明の属する技術分野】
本発明は、石油燃焼機におけるカートリッジタンクの着脱構成に関するものである。
【０００２】
【従来の技術】
従来の構成を燃焼暖房機のタンクを用いて、図１０、図１１、図１２により説明する。図に示すように、タンク本体１の適所に燃料を供給する給油口２を設け、この給油口２に弁機構３を有する給油キャップ４を取り付け、給油口２の端面２ａを給油キャップ４に設けたシール面３ｃでシールすることにより、前記弁機構３を介して給油口２の開放状態と閉塞状態を保つように構成としている。そして、機器５のタンク収納部６にセットするときは、給油口２を下向きにして油受け皿７に載置することで、油受け皿７内に設けた弁押上ピン８により弁体３ｂが押し上げられ、弁機構３が強制的に開放されてタンク本体１内の燃料が油受け皿７に供給され、油受け皿７内の油面が弁機構３の吐出口９に達するとタンク本体１からの燃料の供給が停止する。そして、油受け皿７内の燃料が消費され油面が低下すると、再度タンク本体１からの燃料の供給が開始される。この繰り返しによりタンク本体１から油受け皿７への燃料の供給が行われる。
【０００３】
次に、タンク本体１の燃料が消費され補給が必要となった場合は、機器５からタンク本体１を取り出すことで、弁押上ピン８が弁機構３から離れ、弁機構３は内蔵バネ３ａにより弁体３ｂを吐出口９に密着させることで閉塞状態となりタンク本体１からの燃料の流出を防止する。この状態でタンク本体１を反転させ、給油キャップ４を上向きにして給油キャップ４をゆるめ、給油口２から取り外す。そして、給油口２から燃料を補給したのち、給油キャップ４を給油口２に取り付け、再度機器５に逆転装着することで、油受け皿７への供給が開始されるものである。
【０００４】
この機器５へのタンクの装着はつまり、機器のタンク収納部６にタンクを装着するときは、タンクを機器上部まで持ち上げ、タンク収納部６の上方から装着するようになっている。そして、タンクの持ち運び時は取っ手１０を持って運ぶようになっている（例えば、特許文献１参照）。

【発明が解決しようとする課題】
しかしながら従来の構成においては、給油したあとの燃料が満量となったタンク１を機器に装着するときは、タンク１の重量は大変重くなっていて、使用者の給油の際のもっとも大きな負荷となっている。
【０００７】
特に近年、タンク１は給油回数を減らして給油の手間を省くため、どんどん大容量化されてきており、例えば９リットルのタンク１であれば、タンク１自身の重量が約２ｋｇ、９リットルの燃料が約７．２ｋｇとなり合わせて約９．６ｋｇとなり、さらに燃料をタンク１に給油口すれすれまで入れたとすると、燃料は８ｋｇを超え、燃料とタンク１を合わせた重量が１０ｋｇを超えてしまい、該機器５のタンク１を除いた重量と同等あるいはそれ以上となり、また、タンク１の容量は９．５リットルと９リットルを超えるものもでてきている。また、機器５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、さらに高さの高いものもあり、機器５のタンク収納部６にタンク１を機器５より上部へ持ち上げて装着する作業が大変となっている。
【０００８】
この機器５へのタンク１の装着は、姿勢的にもタンク１を機器５のタンク収納部６の上方へ、体から離して持ち上げなければならなく、負担が大きく、特に上背の低い方や力の弱い人、例えばお年寄りや女性等では困難であった。特に、タンク１に燃料を満量まで入れると、タンク１を機器５上部まで持ち上げられない、あるいは負担が大きいので、燃料をタンク１の途中までしか入れて使わない使用者もあり、それに加え、暖房機は冬場に用いるものであるから、無理な姿勢で重いものを持つと腰痛を引き起こすなど、タンク１の大容量化にともなう課題を生じていた。
【０００９】
本発明は上記問題点に鑑みてなしたもので、機器５へのタンク１の装着を機器５上部まで持ち上げなくても装着できるようにして、使用者の使い勝手の向上を図ることを目的としたものである。
【００１０】
【課題を解決するための手段】
本発明は上記課題を解決するため、機器本体と、燃料を一時的に保有する油受け皿と、油受け皿に着脱自在に設け該油受け皿に燃料を供給する略直方体のタンクと、前記タンクの長手方向の１端面の適所に設けた給油口と、前記タンクを収納するタンク収納部とを備え、前記タンク収納部は上面と側面または背面または前面の何れか２面以上に開放部を有する構成とし、油受け皿にタンクを装着するとき、略水平方向から装着できるようにするとともに、前記タンクは上面に第１取っ手を配設し、前記開放部に対応するタンク側面に第２取っ手を配設した構成としている。
【００１１】
上記発明によれば、タンク収納部に上面と側面または背面または前面の何れか２面以上に開放部を有する構成としてあるので、油受け皿にタンクを装着するとき、タンクを略水平方向から装着できるようになり、タンクを持ち上げずに容易に着脱可能となり、使い勝手が向上する。
【００１２】
また、タンクに燃料を満量入れても持ち上げずに装着することができ、さらに、使用者は無理な姿勢で重量物のタンクを持ち上げなくてもよくなり、腰痛等の心配もなくなる。
【００１３】
また、タンク収納部に油受け皿上部近傍から開閉するトビラを設けると、タンクを持ち上げるとき使用者はタンク上方から持つため、機器本体の上面側と側面側あるいは背面側にトビラを追加しないと使い勝手が悪くなるので、機器本体の上面に開放部を追加すると扉が２つ以上となり、タンクの着脱がツーアクションとなり使い勝手が悪くなるとともに構成が複雑になる。しかしながら、機器本体のタンク収納部の開放部は、機器本体の上面と側面あるいは背面あるいは前面の何れか２面以上を有する構成としてあるので、ワンアクションで油受け皿にタンクを着脱することができるようになり、使い勝手が増すようになり、トビラを設けてないのでタンクの着脱にトビラがじゃまになることもなく使い勝手がさらに増すようになる。
【００１４】
さらに、タンク収納部に油受け皿上部近傍から開閉する開放部を配設してあるので、油やほりなどで汚れた油受け皿の上面を容易に掃除することができ、また、シーズン終わりなどに燃料の油受け皿からの抜き取りも容易になる。
【００１５】
そしてまた、タンクの上面に第１取っ手を配設するともにタンクの上記開放部に面する開放面側のタンク側面に第２取っ手を配設してあるので、持ち運び時には第２取っ手を持って運べるようになり、タンクの重心を使用者の身体の中心に近づけて片手で持てるようになる。つまり、使用者の身体の中心とタンクの重心が近いので使用者はタンクを軽く持てるようになり、また、タンクが長くてもそれを横にして持てるので、床との距離が大きく取れ、タンクを持ち上げて持つ可能性もなくなる。
【００１６】
また、タンクに給油する際のタンクを置く場合に、あるいは機器にタンクをセットする際の、タンクの反転動作を、第２取っ手を持ってできるようになり、反転動作が容易にできるようになり、使い勝手が向上する。
【００１７】
【発明の実施の形態】
本発明の請求項１の石油燃焼暖房機は、機器本体と、燃料を一時的に保有する油受け皿と、油受け皿に着脱自在に設け該油受け皿に燃料を供給する略直方体のタンクと、前記タンクの長手方向の１端面の適所に設けた給油口と、前記タンクを収納するタンク収納部とを備え、前記タンク収納部は上面と側面または背面または前面の何れか２面以上に開放部を有する構成とし、油受け皿にタンクを装着するとき、略水平方向から装着できるようにするとともに、前記タンクは上面に第１取っ手を配設し、前記開放部に対応するタンク側面に第２取っ手を配設した構成としている。
【００１８】
そして、タンク収納部に上面と側面または背面または前面の何れか２面以上に開放部を有する構成としてあるので、油受け皿にタンクを装着するとき、タンクを略水平方向から装着できるようになり、タンクを持ち上げずに容易に着脱可能となり、使い勝手が向上する。
【００１９】
また、請求項２の石油燃焼暖房機は、第２取っ手は、タンクの長手方向のほぼ中間に位置させ、持ち手方向がタンクの長手方向と並行になるように配設してある。
【００２０】
そして、第２取っ手を持って持ち運びする際に、タンクの傾きが規制できるようになり、タンクが大きく傾いて、第２取っ手とタンクで手が挟まれたり、また、タンクの下端が床に近くなって持ちにくくなるなどの心配が無くなる。
【００２１】
また、請求項３の石油燃焼暖房機は、第１取っ手と第２取っ手の持ち手方向が直交するように配設した構成としてある。
【００２２】
そして、第１取っ手と第２取っ手の持ち手方向が直交するように配設してあるので、タンクを置く場合や機器にタンクをセットする際のタンクの反転動作時に、持ち手方向が直交して手を返しやすくなり、反転動作が容易にできるようになる。
【００２３】
また、請求項４の石油燃焼暖房機は、第２取っ手を上面に位置させたときにタンク内の上空間を長手方向と直交するように仕切る仕切板を第２取っ手の下部に１枚あるいはタンク内の適所に複数枚配設した構成としてある。
【００２４】
そして、第２取っ手を上面に位置させたときにタンク内の上空間を長手方向と直交するように仕切る仕切板を第２取っ手の下部に１枚あるいはタンク内の適所に複数枚配設してあるので、持ち運び時のタンク内上部の空間部が仕切板で仕切られ、空間部の移動が規制されるようになる。
【００２５】
つまり、タンク内に液体燃料と空気層を有すると、持ち運び時に、タンクの僅かな傾きでタンク内上部の空間部が移動してしまい、タンク内の液体燃料の重心が動くことによって持ちにくくなるが、タンク内上部の空間部が仕切板で仕切られ、空間部の移動が規制されて、重心部の移動が少なくなり、空間部の移動による持ちにくさが軽減される。これは、仕切る空間の数が多ければ多いほど良く、また、仕切る仕切板の高さは、空間が多く仕切板で仕切られない液体燃料の重心移動があっても、空間が増える分タンクが軽くなって、持ちにくさにあまり支障できないレベルであれば良い。
【００２６】
また、請求項５の石油燃焼暖房機は、仕切板は給油口を下に向け機器にセットしたときにタンク内の燃料が下方に流れるように傾斜させる構成としてある。
【００２７】
そして、仕切板は給油口を下にしたときにタンク内の燃料が下方に流れるように傾斜させてあるので、機器に僅かに傾けてタンクをセットした状態で液体燃料がスムーズに下方に流れ、タンクの液体燃料を使い切ることができるようになる。
【００２８】
また、請求項６の石油燃焼暖房機は、第２取っ手の中心はタンクの重心より給油口側へ近づけて位置させる構成としてある。
【００２９】
そして、上記第２取っ手はタンクの重心より給油口側に近づけて位置させてあるので、持ち運び時にタンクの重心は、第１取っ手に近づいた状態となり、給油口側が反対の第１取っ手側より上になりやすくなり、上記の空間部の移動が規制されて、重心部の移動が少なくなり、簡単な構成で空間部の移動による持ちにくさの軽減の効果が得られる。
【００３０】
また、給油口側が反対の第１取っ手側より上になるので、持ち運び時に給油口を傷つけにくくなるとともに、給油口部より液体燃料が僅かに漏れた場合においても、そのまま床等に落ちて汚すこともなくなる。
【００３１】
また、請求項７の石油燃焼暖房機は、第２取っ手の持ち手部は、給油口が上に傾くように、タンクと傾斜させる構成としてある。
【００３２】
そして、上記第２取っ手の持ち手部は、給油口が上に傾くように、タンクと傾斜させてあるので、請求項６と同様の給油口側が反対の第１取っ手側より上にする効果が得られるとともに、請求項６と組み合わすことで確実性が増す。
【００３３】
また、請求項８の石油燃焼暖房機は、タンクの油量を確認する油量窓は上記開放部に配設した構成としてある。
【００３４】
そして、タンクの油量を確認する油量窓は上記開放部に配設してあるので、タンクの油量が外から見て一目でわかるようになり、使用者が給油時を判断しやすくなり、使い勝手が増すようになる。
【００３５】
また、請求項９の石油燃焼暖房機は、上記第２取っ手はタンクの油量を確認する油量窓のある面に配設した構成としてある。
【００３６】
そして、上記第２取っ手はタンクの油量を確認する油量窓のある面に配設してあるので、タンクに給油する際のタンクを置く場合に、必ずタンクの油量窓の方向が使用者側となり、油量確認をしながら給油することが自然と出来、使い勝手が増すとともに、液体燃料を給油後のタンクの持ち運び時には、重量が重く曲がり角の周囲の壁などと接触して給油口を傷つけやすいが、給油口側が使用者の前方向となり、使用者が注意しやすくなり、給油口を自然と傷つけにくくなる。
【００３７】
また、請求項１０の石油燃焼暖房機は、油受け皿にタンクを装着したときに、タンク収納部の開放部と異なる壁部の適所に磁石を配設した構成としてある。
【００３８】
そして、タンク収納部の開放部と異なる壁部の適所に磁石を配設してあるので、油受け皿にタンクを装着したときに、タンクが機器本体のタンク収納部の開放部と異なる方向に磁力で保持されるようになり、簡単な構成で、タンクが振動など何らかの理由で開放部側に倒れる心配がなくなり、不用意に開放部が開いてタンクがタンク収納部から離脱する心配もなくなり安全性が増すようになるとともに、固定手段を離脱する必要がなくタンクの着脱も容易となる。
【００３９】
また、請求項１１の石油燃焼暖房機は、油受け皿にタンクを装着したときに、タンクが機器本体のタンク収納部の開放部と異なる方向に傾いて保持されるように傾斜保持手段を配設した構成としてある。
【００４０】
そして、請求項１０の効果を他の方法で実現するもので、傾斜保持手段を配設した構成としてあるので、油受け皿にタンクを装着したときに、タンクが機器本体のタンク収納部の開放部と異なる方向に傾いて保持されるようになり、タンクが振動など何らかの理由で開放部側に倒れる心配がなくなり、不用意に開放部が開いてタンクがタンク収納部から離脱する心配もなくなり安全性が増すようになるとともに、タンクの着脱時に固定手段を離脱する必要がなくタンクの着脱も容易となる。
【００４１】
【実施例】
以下本発明の一実施例について、石油燃焼暖房機のタンクを用いて説明する。
【００４２】
（実施例１）
図１は本発明の実施例のタンクの機器への着脱状態を示す斜視図、図２はタンクの構成図、図３は給油キャップの要部断面図、図４はタンクの機器への設置状態を示す要部断面図、図５は持ち運び時の形態を示す図、図６はカートリッジ式給油タンクの給油時の形態を示す図である。
【００４３】
図において、１１は燃料を蓄えておく略直方体のタンク、１２はタンク１１の燃料の量を確認するための油量窓、１３はタンク１１の長手方向の１端面の適所に設けたタンク１１へ燃料の補給と流出を行う給油口、１３ａはこの給油口１３の外周部にもうけたネジ部、１４は給油口１３に着脱自在に設けた給油キャップで、給油キャップ１４の内面に設けたネジ部１４ａと給油口１３のネジ部１３ａとが噛み合うようになっている。
【００４４】
１５は給油キャップ１４内に一体化して設け複数個の貫通孔１５ａを有する弁筒で、内部に弁機構１６を設けている。弁機構１６は給油キャップ１４と弁筒１５間に内装してあり、弁体１７と弁座１８およびバネ１９で構成し、給油キャップ１４の吐出口２０の開閉を行う。２１は石油燃焼器のバーナへ燃料を供給するために一時蓄えておくための油受け皿、２２は油受け皿２１の上部開口に取り付けた受け口であり、該受け口２２には弁押し上げピン２３が突起して形成してある。
【００４５】
２４は給油口１３の反対側のタンク１１の長手方向の１端面の適所に設けた第１取っ手で、この第１取っ手２４と給油口１３のほぼ中間に位置し、油量窓１２のあるタンク１１側面の適所にタンク１１の長手方向と並行になるように第２取っ手２５を配設してあり、第１取っ手２４と第２取っ手２５の持ち手方向が直交するようにしてある。
【００４６】
２６は、第２取っ手２５を上面に位置させたときにタンク１１内の上空間を長手方向と直交するように仕切る仕切板で、第２取っ手２５の下部にタンク１１内の適所に複数枚配設するとともに、上記仕切板２６は給油口１３を下に向け該機器にセットしたときにタンク１１内の燃料が下方に流れるように傾斜させてある。
【００４７】
そして、油受け皿２１は機器本体の下部に配設してあり、通常は着脱自在に設けたタンク１１を載置して、該油受け皿２１に燃料を供給するようにしてあり、機器本体の油受け皿２１上部にはタンク１１を収納するタンク収納部２７が配設してあり、このタンク収納部２７には油受け皿２１にタンク１１を装着するときにタンク１１を略水平方向に装着出来るようタンク収納部２７に油受け皿２１上部近傍から開放部２８を配設してある。
【００４８】
この開放部２８は、機器本体の上面と側面と背面の３面を開放する構成とするとともに、油受け皿２１にタンク１１を装着したときに、機器本体の上面すなわちタンク１１の上面に第１取っ手を配設するともにタンク１１の上記開放部２８に面する機器本体の側面に位置する開放面側のタンク１１側面に第２取っ手を配設し、かつ、タンク１１の油量を確認する油量窓１２を設けてある。
【００４９】
上記構成において、その動作を説明すると、まず、タンク１１を給油キャップ１４を下向きにして油受け皿２１の受け口２２に装着すると、弁押し上げピン２３が弁体１７をバネ１９に抗して押し上げ、弁座１８による給油キャップ１４の吐出口２０の閉塞状態が解除される。これにより、タンク１１の燃料は受け口２２を介して油受け皿２１内に供給され、給油キャップ１４の吐出口２０の油面高さまで蓄えられる。そして、バーナで消費され油受け皿２１内の油面が低下すると、吐出口２０よりタンク１１内に空気が入り、この空気の置換作用でタンク１１の燃料は油受け皿２１内に供給される。この繰り返しにより油受け皿２１内の油面は一定油面を保持する。そして、タンク１１内の燃料が給油キャップ１４の端部つまり吐出口２０まで減少してくると、弁筒１５の外周部に設けた複数の貫通孔１５ａより燃料の供給は継続され、タンク１１内の燃料はほとんど使いきることになる。
【００５０】
次に、タンク１１の燃料が空になると、タンク１１を受け口２２から取り外す。このとき、弁機構１６は弁押し上げピン２３で弁体１７を押し上げていた動作が解除されるため、弁体１７はバネ１９により元の状態に戻り、弁座１８を介して吐出口２０を閉塞状態に保つ。そして、タンク１１を給油場所まで運び、給油キャップ１４を取り外してサイフォンポンプなどで給油を行う。
【００５１】
ここで、タンク収納部２７に油受け皿上部近傍から開放部２８を配設するとともに、上記開放部２８は、機器本体の上面と側面と背面の３面を有するようにあるので、油受け皿にタンク１１を装着するときにタンク１１を略水平方向に装着出来るようになり、タンク１１を持ち上げずに使用者は着脱が容易にすることができ、使い勝手が増すようになる。
【００５２】
また、タンク１１に燃料を満量入れても持ち上げずに装着することができ、さらに、使用者は無理な姿勢で重量物のタンク１１を持ち上げなくてもよくなり、腰痛等の心配もなくなる。
【００５３】
さらに、タンク収納部２７に油受け皿２１上部近傍から開閉するトビラを設けると、タンク１１を持ち上げるとき使用者はタンク１１上方から持つため、機器本体の上面側と側面側あるいは背面側にトビラを追加しないと使い勝手が悪くなるので、機器本体の上面に開放部２８を追加すると扉が２つ以上となり、タンク１１の着脱がツーアクションとなり使い勝手が悪くなるとともに構成が複雑になる。しかしながら、機器本体のタンク収納部２７の開放部２８は、機器本体の上面と側面と背面の３面を有する構成としてあるので、ワンアクションで油受け皿２１にタンク１１を着脱することができるようになり、使い勝手が増すようになり、トビラを設けてないのでタンク１１の着脱にトビラがじゃまになることもなく使い勝手がさらに増すようになる。
【００５４】
さらに、タンク収納部２７に油受け皿２１上部近傍から開閉する開放部２８を配設してあるので、油やほりなどで汚れた油受け皿２１の上面を容易に掃除することができ、また、シーズン終わりなどに燃料の油受け皿２１からの抜き取りも容易になる。
【００５５】
そしてまた、タンク１１の上面に第１取っ手を配設するともにタンク１１の上記開放部２８に面する開放面側のタンク１１側面に第２取っ手２５を配設してあるので、持ち運び時には第２取っ手２５を持って運べるようになり、タンク１１の重心を使用者の身体の中心に近づけて片手で持てるようになる。つまり、使用者の身体の中心とタンク１１の重心が近いので使用者はタンク１１を軽く持てる様なり、また、タンク１１が長くてもそれを横にして持てるので、床との距離が大きく取れ、タンク１１を持ち上げて持つ可能性もなくなる。
【００５６】
さらに、タンク１１に給油する際のタンク１１を置く場合に、あるいは機器にタンク１１をセットする際の、タンク１１の反転動作を、第２取っ手２５を持って出来るようになり、反転動作が容易に出来るようになり、使い勝手が増す。
【００５７】
そして、第２取っ手２５は、タンク１１の長手方向のほぼ中間に位置させ、かつ、持ち手方向がタンク１１の長手方向と並行になるように配設してあるので、第２取っ手２５を持って持ち運びする際に、タンク１１の傾きが規制出来るようになり、タンク１１が大きく傾いて、第２取っ手２５とタンク１１で手が挟まれたり、また、タンク１１の下端が床に近くなって持ちにくくなるなどの心配が無くなる。
【００５８】
また、第１取っ手２４と第２取っ手２５の持ち手方向が直交するように配設してあるので、第１取っ手２４と第２取っ手２５を両方持つタンク１１に給油する際のタンク１１を置く場合に、あるいは機器にタンク１１をセットする際の、タンク１１の反転動作時に、持ち手方向が直交して手を返しやすくなり、反転動作が容易に出来るようになる。
【００５９】
さらに、第２取っ手２５を上面に位置させたときにタンク１１内の上空間を長手方向と直交するように仕切る仕切板２６を第２取っ手２５の下部に１枚あるいはタンク１１内の適所に複数枚配設してあるので、持ち運び時のタンク１１内上部の空間部が仕切板２６で仕切られ、空間部の移動が規制されるようになる。
【００６０】
つまり、タンク１１内に液体燃料と空気層を有すると、持ち運び時に、タンク１１の僅かな傾きでタンク１１内上部の空間部が移動してしまい、タンク１１内の液体燃料の重心が動くことによって持ちにくくなるが、タンク１１内上部の空間部が仕切板２６で仕切られ、空間部の移動が規制されるので、図５の（ａ）、（ｂ）、（ｃ）にシメすように、重心部の移動が少なくなり、空間部の移動による持ちにくさが軽減される。これは、仕切る空間の数が多ければ多いほど良く、また、仕切る仕切板２６の高さは、空間が多く仕切板２６で仕切られない液体燃料の重心移動があっても、空間が増える分タンク１１が軽くなって、持ちにくさにあまり支障できないレベルであれば良い。
【００６１】
そしてまた、仕切板２６は給油口を下にしたときにタンク１１内の燃料が下方に流れるように傾斜させてあるので、機器に僅かに傾けてタンク１１をセットした状態で液体燃料がスムーズに下方に流れ、タンク１１の液体燃料を使い切ることが出来るようになる。
【００６２】
さらに、タンク１１の油量を確認する油量窓は上記開放部２８に配設してあるので、タンク１１の油量が外から見て一目でわかるようになり、使用者が給油時を判断しやすくなり、使い勝手が増すようになる。
【００６３】
そして、上記第２取っ手２５はタンク１１の油量を確認する油量窓のある面に配設してあるので、タンク１１に給油する際のタンク１１を置く場合に、必ずタンク１１の油量窓の方向が使用者側となり、油量確認をしながら給油することが自然と出来、使い勝手が増すとともに、液体燃料を給油後のタンク１１の持ち運び時には、重量が重く曲がり角の周囲の壁などと接触して給油口を傷つけやすいが、給油口側が使用者の前方向となり、使用者が注意しやすくなり、給油口を自然と傷つけにくくなる。
【００６４】
（実施例２）
図７は本発明の実施例２のタンクの構成図である。実施例１で述べた部分と同じ部分は同一番号を付記して説明を省略し、異なる部分のみを説明する。
【００６５】
図７において、上記第２取っ手３３の中心はタンク３１の重心より給油口３４側へ近づけて位置させかつ、第２取っ手３３の持ち手部は、給油口３４が上に傾くように、タンク３１と傾斜させた構成としてある。
【００６６】
上記構成において、上記第２取っ手３３の中心はタンク３１の重心より給油口３４側へ近づけて位置させかつ、第２取っ手３３の持ち手部は、給油口３４が上に傾くように、タンク３１と傾斜させてあるので、持ち運び時にタンク３１の重心は、第１取っ手３２に近づいた状態となり、給油口３４側が反対の第１取っ手３２側より上になりやすくなり、上記の空間部の移動が規制されて、重心部の移動が少なくなり、簡単な構成で実施例１の空間部の移動による持ちにくさが軽減の効果が得られる。
【００６７】
また、給油口３４側が反対の第１取っ手３２側より上になるので、持ち運び時に給油口３４を傷つけにくくなるとともに、給油口３４部より液体燃料が僅かに漏れた場合においても、そのまま床等に落ちて汚すこともなくなる。
【００６８】
さらに、実施例１に示すような仕切板２６が必要となくなるので構成も簡単となり、安価に使い勝手を増すことが出来るようになる。
【００６９】
（実施例３）
図８は本発明の実施例３の機器への設置状態を示す要部断面図である。実施例１で述べた部分と同じ部分は同一番号を付記して説明を省略し、異なる部分のみを説明する。
【００７０】
図８において、タンク収納部４１の開放部４２と異なる壁には、油受け皿４３にタンク４４を装着したときに、タンク４４を機器本体のタンク収納部４１の開放部４２と異なる壁に保持されるように固定手段の磁石４５を配設してある。
【００７１】
上記構成において、タンク収納部４１の開放部４５と異なる壁部の適所に磁石を配設してあるので、油受け皿４３にタンク４４を装着したときに、タンク４４が機器本体のタンク収納部４１の開放部４２と異なる方向に磁力で保持されるようになり、簡単な構成で、タンク４４が振動など何らかの理由で開放部４２側に倒れる心配がなくなり、不用意に開放部４２が開いてタンク４４がタンク収納部４１から離脱する心配もなくなり安全性が増すようになるとともに、固定手段を離脱する必要がなくタンク４４の着脱も容易となる。
【００７２】
（実施例４）
図９は本発明の実施例４の機器への設置状態を示す要部断面図である。実施例１で述べた部分と同じ部分は同一番号を付記して説明を省略し、異なる部分のみを説明する。
【００７３】
図９において、油受け皿５１にタンク５２を装着したときに、タンク５２が機器本体のタンク収納部５３の開放部５４と異なる方向に傾いて保持されるように開放部５４側の油受け皿５１の上面に突起部５１ａを配設した構成としてある。
【００７４】
上記した構成において、実施例３の効果を他の方法で実現するもので、傾斜保持手段である開放部５４側の油受け皿５１の上面に突起部５１ａを配設した構成としてあるので、油受け皿５１にタンク５２を装着したときに、タンク５２が機器本体のタンク収納部５３の開放部５４と異なる方向に傾いて保持されるようになり、タンク５２が振動など何らかの理由で開放部５４側に倒れる心配がなくなり、不用意に開放部５４が開いてタンク５２がタンク収納部５３から離脱する心配もなくなり安全性が増すようになるとともに、タンク５２の着脱時に固定手段を離脱する必要がなくタンク５２の着脱も容易となる。
【００７５】
なお上記実施例は、第１取っ手２４と第２取っ手２５の持ち手方向を直交させる構成と、タンク１１内の上空間を長手方向と直交するように仕切る仕切板２６を配設する構成と、仕切板２６を傾斜させた構成と、第２取っ手２５はタンク１１の油量を確認する油量窓１２のある面に配設する構成を同時に説明したが、これは個別にしてもよく、第２取っ手３３の中心をタンク３１の重心より第１取っ手３２より遠ざけて位置させた構成と、第２取っ手を傾斜させた構成を同時に説明したが、これは個別にしてもよく、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。
【００７６】
【発明の効果】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a configuration for attaching and detaching a cartridge tank in an oil-fired machine.
[0002]
[Prior art]
A conventional configuration will be described with reference to FIGS. 10, 11, and 12 using a tank of a combustion heater. As shown in the figure, a fuel supply port 2 for supplying fuel is provided at an appropriate position in a tank body 1, a fuel supply cap 4 having a valve mechanism 3 is attached to the fuel supply port 2, and an end face 2a of the fuel supply port 2 is provided in the fuel supply cap 4. The oil supply port 2 is kept open and closed via the valve mechanism 3 by sealing with the sealing surface 3c. Then, when the device 3 is set in the tank storage section 6, the valve body 3 b is pushed up by the valve push-up pin 8 provided in the oil receiving tray 7 by placing the oil filler port 2 downward and placing the oil receiving tray 7 on the oil receiving tray 7. When the valve mechanism 3 is forcibly opened and the fuel in the tank body 1 is supplied to the oil receiving tray 7 and the oil level in the oil receiving tray 7 reaches the discharge port 9 of the valve mechanism 3, the fuel from the tank body 1 is discharged. Supply stops. Then, when the fuel in the oil receiving tray 7 is consumed and the oil level decreases, the supply of the fuel from the tank body 1 is started again. By this repetition, the supply of fuel from the tank body 1 to the oil receiving tray 7 is performed.
[0003]
Next, when the fuel in the tank body 1 is consumed and replenishment is required, the tank body 1 is taken out of the device 5, the valve push-up pin 8 is separated from the valve mechanism 3, and the valve mechanism 3 is moved by the built-in spring 3a. The valve body 3b is brought into a closed state by bringing the valve body 3b into close contact with the discharge port 9, thereby preventing the fuel from flowing out of the tank body 1. In this state, the tank body 1 is turned over, the oil supply cap 4 is turned upward, the oil supply cap 4 is loosened, and the oil supply cap 2 is removed. After the fuel is supplied from the fuel filler 2, the fuel filler cap 4 is attached to the fuel filler 2, and the device 5 is reversely mounted again, so that the supply to the oil receiving tray 7 is started.
[0004]
When the tank is mounted on the device 5, that is, when the tank is mounted on the tank storage portion 6 of the device, the tank is lifted up to the upper portion of the device and mounted from above the tank storage portion 6. When the tank is carried, the handle 10 is held and carried (for example, see Patent Document 1).

[0006]
[Problems to be solved by the invention]
However, in the conventional configuration, when the tank 1 that is full of fuel after refueling is mounted on the equipment, the weight of the tank 1 is very heavy, and the largest load and the maximum load when the user refuels. Has become.
[0007]
In particular, in recent years, the capacity of the tank 1 has been steadily increased in order to reduce the number of times of refueling and to save time for refueling. For example, if the tank 1 is 9 liters, the weight of the tank 1 itself is about 2 kg and the fuel of 9 liters is used. Is about 7.2 kg, which is about 9.6 kg. If the fuel is put into the tank 1 just below the filler opening, the fuel exceeds 8 kg, and the total weight of the fuel and the tank 1 exceeds 10 kg. The weight of the equipment 5 is equal to or greater than the weight of the tank 1 excluding the tank 1, and the capacity of the tank 1 is 9.5 liters or more than 9 liters. In addition, from the viewpoint of saving space for installation, the form of the device 5 has been increased in a vertically long form than in a horizontally long form, and some of the forms have a higher height. The task of lifting to the top and mounting it is difficult.
[0008]
In order to mount the tank 1 on the device 5, the tank 1 must be lifted above the tank storage portion 6 of the device 5 away from the body, and the burden is large. It was difficult for weak people, such as the elderly and women. In particular, if the tank 1 is filled with the fuel to its full capacity, the tank 1 cannot be lifted to the upper part of the equipment 5 or the burden is large. Since the heater is used in the winter, there is a problem associated with increasing the capacity of the tank 1, such as causing back pain when holding a heavy object in an unreasonable posture.
[0009]
The present invention has been made in view of the above problems, and has as its object to improve the usability of a user by allowing the tank 1 to be mounted on the device 5 without lifting it up to the upper portion of the device 5. Things.
[0010]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides an apparatus main body, an oil pan for temporarily holding fuel, a substantially rectangular parallelepiped tank which is detachably mounted on the oil pan and supplies fuel to the oil pan, and a longitudinal section of the tank. A fuel supply port provided at an appropriate position on one end face in the direction, and a tank storage portion for storing the tank, wherein the tank storage portion has an open portion on any two or more of the upper surface and the side surface or the rear surface or the front surface. When mounting the tank on the oil pan, the tank can be mounted from a substantially horizontal direction, and the tank has a first handle disposed on the upper surface and a second handle disposed on the side of the tank corresponding to the opening. It has a configuration.
[0011]
According to the above invention, since the tank storage portion has an opening on any two or more of the upper surface and the side surface or the rear surface or the front surface, when the tank is mounted on the oil receiving tray, the tank can be mounted from a substantially horizontal direction. As a result, the tank can be easily attached and detached without lifting, and the usability is improved.
[0012]
Further, even if the tank is filled with fuel, the fuel tank can be mounted without lifting, and the user does not have to lift the heavy tank in an unreasonable posture, so that there is no worry about lower back pain or the like.
[0013]
In addition, if a tobira that opens and closes from the upper part of the oil pan is provided in the tank storage part, the user holds it from above the tank when lifting the tank, so it is easy to use unless the tobira is added to the top and side surfaces or the back side of the equipment body. If the opening is added to the upper surface of the apparatus main body, the number of doors becomes two or more, and the attachment and detachment of the tank becomes a two-action operation, which deteriorates usability and complicates the configuration. However, since the open portion of the tank storage portion of the device main body is configured to have any two or more of the upper surface and the side surface, the rear surface, or the front surface of the device main body, the tank can be attached to and detached from the oil pan with one action. , The usability is increased, and since the tobira is not provided, the usability is further increased without disturbing the attachment and detachment of the tank.
[0014]
In addition, an opening that opens and closes near the top of the oil pan is provided in the tank storage area, so that the top of the oil pan that is contaminated with oil or dust can be easily cleaned. Can be easily extracted from the oil pan.
[0015]
Further, since the first handle is provided on the upper surface of the tank and the second handle is provided on the side of the tank on the open side facing the open portion of the tank, the second handle can be carried when carrying. As a result, the center of gravity of the tank can be brought closer to the center of the user's body and held with one hand. In other words, since the center of the body of the user and the center of gravity of the tank are close, the user can hold the tank lightly.Also, even if the tank is long, it can be held sideways, so the distance to the floor can be increased, The possibility of lifting and holding is also eliminated.
[0016]
In addition, when the tank is placed for refueling the tank or when the tank is set in the equipment, the tank can be turned over with the second handle, so that the turning operation can be easily performed. , The usability is improved.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
The oil-fired heating machine according to claim 1 of the present invention includes an apparatus main body, an oil pan temporarily holding fuel, a substantially rectangular parallelepiped tank detachably provided on the oil pan, and supplying fuel to the oil pan. An oil supply port provided at an appropriate position on one end face in the longitudinal direction of the tank, and a tank storage portion for storing the tank, wherein the tank storage portion has an open portion on any two or more of the upper surface and the side surface or the rear surface or the front surface. When mounting the tank on the oil pan, the tank can be mounted from a substantially horizontal direction, the tank has a first handle disposed on the upper surface, and a second handle is disposed on a tank side surface corresponding to the opening. It is configured to be installed.
[0018]
And since it has a structure which has an open part in any two or more of the upper surface and the side surface or the back surface or the front surface in the tank storage part, when the tank is mounted on the oil receiving tray, the tank can be mounted from a substantially horizontal direction, The tank can be easily attached and detached without lifting, improving usability.
[0019]
In the oil-fired heater according to the second aspect, the second handle is located substantially at the center of the longitudinal direction of the tank, and the handle is arranged so as to be parallel to the longitudinal direction of the tank.
[0020]
And when carrying the second handle, the inclination of the tank can be regulated, and the tank is greatly inclined, the hand is pinched between the second handle and the tank, and the lower end of the tank is close to the floor. There is no need to worry about it becoming difficult to hold.
[0021]
Further, the oil-fired heating machine according to claim 3 has a configuration in which the first handle and the second handle are arranged so that the handle directions are orthogonal to each other.
[0022]
Since the handle direction of the first handle and the handle of the second handle are arranged orthogonally, when the tank is placed or when the tank is turned over when the tank is set in the device, the handle directions are orthogonal. The hand can be easily turned back, and the reversing operation can be easily performed.
[0023]
In the oil-fired heater according to claim 4, one or more partition plates or tanks are provided below the second handle to partition the upper space in the tank when the second handle is located on the upper surface so as to be orthogonal to the longitudinal direction. It has a configuration in which a plurality of sheets are arranged at appropriate places in the inside.
[0024]
Then, one or a plurality of partition plates are provided at the lower portion of the second handle to partition the upper space in the tank so as to be orthogonal to the longitudinal direction when the second handle is positioned on the upper surface. Because of this, the upper space in the tank when being carried is partitioned by a partition plate, and the movement of the space is regulated.
[0025]
In other words, if a liquid fuel and an air layer are provided in the tank, the space above the tank moves due to a slight inclination of the tank when being carried, and it becomes difficult to hold the liquid fuel in the tank by moving the center of gravity of the liquid fuel. The space in the upper part of the tank is partitioned by a partition plate, and the movement of the space is restricted, so that the movement of the center of gravity is reduced, and the difficulty in holding the space due to the movement of the space is reduced. This is better if the number of spaces to be partitioned is large, and the height of the partition is small even if there is a shift in the center of gravity of the liquid fuel, which is too large to be partitioned by the partition, and the tank becomes lighter as the space increases. It is good if it is a level that does not hinder the difficulty of holding.
[0026]
Further, the oil-fired heating machine according to claim 5 is configured such that the partition plate is inclined so that the fuel in the tank flows downward when the filler plate is set to the device with the filler port facing downward.
[0027]
And since the partition plate is inclined so that the fuel in the tank flows downward when the filler port is down, the liquid fuel flows smoothly downward with the tank set slightly inclined to the equipment, The liquid fuel in the tank can be used up.
[0028]
Further, the oil-fired heater of claim 6 is configured such that the center of the second handle is located closer to the refueling port side than the center of gravity of the tank.
[0029]
Since the second handle is positioned closer to the filler port than the center of gravity of the tank, the center of gravity of the tank is closer to the first handle when carrying, and the filler port side is higher than the opposite first handle side. The movement of the space is restricted, the movement of the center of gravity is reduced, and the effect of reducing the difficulty of holding by the movement of the space can be obtained with a simple configuration.
[0030]
In addition, since the fuel filler side is higher than the opposite first handle side, it is difficult to damage the fuel filler port when carrying, and even if the liquid fuel leaks slightly from the fuel filler part, it falls on the floor or the like as it is and becomes dirty. Is also gone.
[0031]
Further, the oil-fired heating machine according to claim 7 is configured such that the handle portion of the second handle is inclined with the tank so that the fuel filler port is inclined upward.
[0032]
Since the handle portion of the second handle is inclined with respect to the tank so that the filler port is inclined upward, the same effect as in claim 6 can be obtained in which the filler port side is higher than the opposite first handle side. In addition to being obtained, certainty is increased by combining with claim 6.
[0033]
Further, the oil-fired heating machine according to claim 8 is configured such that an oil amount window for checking the oil amount in the tank is disposed in the opening.
[0034]
And, since the oil amount window for checking the oil amount of the tank is located at the above-mentioned open part, the oil amount of the tank can be seen at a glance from the outside, so that the user can easily determine when to refuel. , Increasing usability.
[0035]
The oil-fired heating machine according to claim 9 is configured such that the second handle is disposed on a surface having an oil amount window for checking the oil amount in the tank.
[0036]
Since the second handle is provided on the surface with the oil amount window for checking the oil amount of the tank, the direction of the oil amount window of the tank must be used when placing the tank when refueling the tank. It is natural for the user to be able to refuel while checking the oil level, which increases the usability, and when the liquid fuel is refueled, when carrying the tank, the heavy fuel tank comes into contact with the wall around the corner and turns the refueling port. Although it is easy to be damaged, the filler port side is in front of the user, which makes it easier for the user to pay attention, and the filler port is not easily damaged naturally.
[0037]
The oil-fired heater according to claim 10 is configured such that when the tank is mounted on the oil pan, a magnet is disposed at an appropriate position on a wall different from the open portion of the tank storage portion.
[0038]
Since magnets are arranged at appropriate places on the wall different from the open part of the tank storage part, when the tank is mounted on the oil pan, the tank will be magnetized in a different direction from the open part of the tank storage part of the equipment body. With a simple configuration, there is no need to worry about the tank falling to the open side for any reason, such as vibration, and there is no worry about the open section being opened and the tank being detached from the tank storage section. As a result, it is not necessary to detach the fixing means, and the tank can be easily attached and detached.
[0039]
In the oil-fired heating machine according to the eleventh aspect, when the tank is mounted on the oil pan, the tilt holding means is disposed so that the tank is tilted and held in a direction different from the opening of the tank storage portion of the device body. There is a configuration.
[0040]
The effect of claim 10 is realized by another method. Since the tilt holding means is provided, when the tank is mounted on the oil pan, the tank is opened at the tank storage portion of the device body. The tank is tilted and held in a different direction from the above, so there is no need to worry about the tank falling to the open side for any reason such as vibration, and there is no worry about the open section being opened carelessly and the tank detaching from the tank storage section. And the fixing means does not have to be detached when the tank is attached or detached, and the tank can be easily attached or detached.

[0044]
Reference numeral 15 denotes a valve cylinder provided integrally with the fuel supply cap 14 and having a plurality of through holes 15a, and a valve mechanism 16 is provided therein. The valve mechanism 16 is provided between the fuel cap 14 and the valve cylinder 15, and includes a valve body 17, a valve seat 18, and a spring 19, and opens and closes the discharge port 20 of the fuel cap 14. Reference numeral 21 denotes an oil pan for temporarily storing fuel for supplying fuel to the burner of the oil combustor. Reference numeral 22 denotes a socket attached to an upper opening of the oil pan 21, and a valve push-up pin 23 projects from the socket 22. It is formed.
[0045]
Reference numeral 24 denotes a first handle provided at an appropriate position on one longitudinal end face of the tank 11 on the opposite side of the oil filler 13, and a tank having an oil amount window 12 located substantially in the middle between the first handle 24 and the oil filler 13. A second handle 25 is arranged at an appropriate position on the side surface of the tank 11 so as to be parallel to the longitudinal direction of the tank 11, and the handle directions of the first handle 24 and the second handle 25 are orthogonal to each other.
[0046]
Reference numeral 26 denotes a partition plate which partitions the upper space in the tank 11 so as to be orthogonal to the longitudinal direction when the second handle 25 is positioned on the upper surface. In addition, the partition plate 26 is inclined so that the fuel in the tank 11 flows downward when the fuel supply port 13 is set downward and the apparatus is set in the apparatus.
[0047]
The oil pan 21 is disposed at the lower portion of the main body of the apparatus. The tank 11 which is usually detachably provided is mounted thereon to supply fuel to the oil pan 21. A tank storage portion 27 for storing the tank 11 is disposed above the receiving tray 21. The tank storage portion 27 is provided so that the tank 11 can be mounted substantially horizontally when the tank 11 is mounted on the oil receiving tray 21. An opening portion 28 is provided in the storage portion 27 from near the upper portion of the oil receiving tray 21.
[0048]
The opening 28 is configured to open the upper surface, the side surface, and the rear surface of the device main body, and when the tank 11 is mounted on the oil receiving tray 21, the first handle is provided on the upper surface of the device main body, that is, the upper surface of the tank 11. And the second handle is disposed on the side of the tank 11 on the open side located on the side of the equipment body facing the open portion 28 of the tank 11, and the amount of oil for confirming the amount of oil in the tank 11 A window 12 is provided.
[0049]
In the above configuration, the operation will be described. First, when the tank 11 is attached to the receiving port 22 of the oil receiving tray 21 with the oil supply cap 14 facing downward, the valve push-up pin 23 pushes up the valve element 17 against the spring 19, The closed state of the discharge port 20 of the refueling cap 14 by the seat 18 is released. As a result, the fuel in the tank 11 is supplied into the oil receiving tray 21 through the receiving port 22 and is stored up to the oil level of the discharge port 20 of the refueling cap 14. Then, when the oil level in the oil pan 21 is reduced by consumption by the burner, air enters the tank 11 through the discharge port 20, and the fuel in the tank 11 is supplied into the oil pan 21 by the air replacement action. By repeating this, the oil level in the oil receiving tray 21 is kept constant. When the fuel in the tank 11 decreases to the end of the refueling cap 14, that is, to the discharge port 20, the supply of the fuel is continued from the plurality of through holes 15 a provided in the outer periphery of the valve cylinder 15, Will run out of fuel.
[0050]
Next, when the fuel in the tank 11 becomes empty, the tank 11 is removed from the receiving port 22. At this time, since the operation of the valve mechanism 16 pushing up the valve element 17 by the valve push-up pin 23 is released, the valve element 17 returns to the original state by the spring 19 and closes the discharge port 20 via the valve seat 18. Keep in condition. Then, the tank 11 is carried to a refueling place, the refueling cap 14 is removed, and refueling is performed by a siphon pump or the like.
[0051]
Here, an open portion 28 is provided in the tank storage portion 27 from the vicinity of the upper portion of the oil pan, and since the open portion 28 has three surfaces, that is, the upper surface, the side surface, and the rear surface of the device main body, the tank is provided in the oil pan. When the tank 11 is mounted, the tank 11 can be mounted in a substantially horizontal direction, so that the user can easily attach and detach the tank 11 without lifting the tank 11, thereby increasing the usability.
[0052]
In addition, even if the tank 11 is full of fuel, the tank 11 can be mounted without lifting, and the user does not need to lift the heavy tank 11 in an unreasonable posture, and there is no worry about back pain or the like.
[0053]
Further, if a tobira that opens and closes from the vicinity of the upper portion of the oil receiving tray 21 is provided in the tank storage portion 27, the user holds the tank 11 from above when the tank 11 is lifted. If the opening 28 is added to the upper surface of the device main body, the number of doors becomes two or more, and the attachment / detachment of the tank 11 becomes two-action, so that the usability is deteriorated and the configuration becomes complicated. However, since the open portion 28 of the tank storage portion 27 of the device main body is configured to have three surfaces of the top surface, the side surface, and the back surface of the device main body, the tank 11 can be attached to and detached from the oil pan 21 in one action. As a result, the convenience is increased, and since the tobira is not provided, the usability is further increased without disturbing the attachment and detachment of the tank 11.
[0054]
Further, since an opening 28 that opens and closes from the vicinity of the upper portion of the oil receiving tray 21 is provided in the tank storage portion 27, the upper surface of the oil receiving tray 21 that is dirty with oil or dust can be easily cleaned, and the season At the end, the fuel can be easily extracted from the oil pan 21.
[0055]
Further, since the first handle is provided on the upper surface of the tank 11 and the second handle 25 is provided on the side surface of the tank 11 on the open surface side facing the open portion 28 of the tank 11, the second handle 25 is provided when the portable device is carried. The user can carry the handle 25 and bring the center of gravity of the tank 11 closer to the center of the body of the user, and can hold the tank 11 with one hand. In other words, since the center of the body of the user and the center of gravity of the tank 11 are close to each other, the user can hold the tank 11 lightly, and even if the tank 11 is long, it can be held sideways, so that the distance from the floor can be increased. Thus, there is no possibility of holding the tank 11 by lifting it.
[0056]
Furthermore, when the tank 11 is placed when refueling the tank 11 or when the tank 11 is set in the apparatus, the reversing operation of the tank 11 can be performed by holding the second handle 25, which facilitates the reversing operation. And the usability increases.
[0057]
The second handle 25 is located substantially at the center of the longitudinal direction of the tank 11 and is disposed so that the handle direction is parallel to the longitudinal direction of the tank 11. When carrying, the inclination of the tank 11 can be regulated, the tank 11 is greatly inclined, and the hand is pinched between the second handle 25 and the tank 11, or the lower end of the tank 11 is close to the floor. There is no need to worry about it becoming difficult to hold.
[0058]
Also, since the handle direction of the first handle 24 and the second handle 25 is disposed orthogonally, the tank 11 for refueling the tank 11 having both the first handle 24 and the second handle 25 is placed. In such a case, or when the tank 11 is set in the device, at the time of the reversing operation of the tank 11, the holding direction is orthogonal and the hand is easily turned, so that the reversing operation can be easily performed.
[0059]
Further, one partition plate 26 for partitioning the upper space in the tank 11 so as to be orthogonal to the longitudinal direction when the second handle 25 is positioned on the upper surface, or a plurality of partition plates 26 at a proper position in the tank 11 is provided. Since the sheets are arranged, the upper space in the tank 11 when being carried is partitioned by the partition plate 26, and the movement of the space is regulated.
[0060]
In other words, when the liquid fuel and the air layer are provided in the tank 11, the space above the tank 11 moves due to a slight inclination of the tank 11 when being carried, and the center of gravity of the liquid fuel in the tank 11 moves. Although it is difficult to hold the space, the upper space in the tank 11 is partitioned by the partition plate 26, and the movement of the space is regulated. As shown in FIGS. 5 (a), 5 (b) and 5 (c), The movement of the center of gravity is reduced, and the difficulty of holding by the movement of the space is reduced. This is better as the number of spaces to be partitioned is larger, and the height of the partitioning plate 26 is set to a value corresponding to the increased space even if the center of gravity of the liquid fuel that is too large to be partitioned by the partitioning plate 26 moves. It suffices that the level 11 is light enough to make it hard to hold.
[0061]
Further, since the partition plate 26 is inclined so that the fuel in the tank 11 flows downward when the fuel filler is turned down, the liquid fuel can be smoothly supplied in a state where the tank 11 is set slightly inclined to the device. It flows downward, and the liquid fuel in the tank 11 can be used up.
[0062]
Further, since the oil amount window for checking the oil amount of the tank 11 is provided in the opening 28, the oil amount of the tank 11 can be seen at a glance from the outside, so that the user can judge when to refuel. It becomes easy to use and the usability increases.
[0063]
Since the second handle 25 is provided on the surface having the oil amount window for checking the oil amount of the tank 11, when the tank 11 is refilled, the oil amount of the tank 11 must be always set. The direction of the window is the user's side, and it is naturally possible to refuel while checking the amount of oil, which increases the usability, and when carrying the tank 11 after refueling the liquid fuel, the weight is heavy and the wall around the corner is turned. Although the filler hole is easily damaged by contact, the filler side is in front of the user, which makes it easier for the user to pay attention, and the filler hole is not easily damaged naturally.
[0064]
(Example 2)
FIG. 7 is a configuration diagram of the tank according to the second embodiment of the present invention. The same portions as those described in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Only different portions will be described.
[0065]
In FIG. 7, the center of the second handle 33 is positioned closer to the refueling port 34 side than the center of gravity of the tank 31, and the handle of the second handle 33 is positioned so that the refueling port 34 is inclined upward. It is configured to be inclined.
[0066]
In the above configuration, the center of the second handle 33 is positioned closer to the refueling port 34 side than the center of gravity of the tank 31, and the handle of the second handle 33 is positioned so that the refueling port 34 is inclined upward. When carrying the tank 31, the center of gravity of the tank 31 becomes closer to the first handle 32, and the refueling port 34 tends to be higher than the opposite first handle 32, so that the movement of the space described above is prevented. The movement of the center of gravity is reduced due to the restriction, and the effect of reducing the difficulty of holding by the movement of the space in the first embodiment can be obtained with a simple configuration.
[0067]
In addition, since the refueling port 34 side is higher than the opposite first handle 32 side, it is difficult to damage the refueling port 34 when carrying, and even when the liquid fuel slightly leaks from the refueling port 34 part, it is still on the floor or the like. It will not fall and become dirty.
[0068]
Further, since the partition plate 26 as shown in the first embodiment is not required, the configuration is simplified, and the usability can be increased at low cost.

FIG. 8 is a cross-sectional view of a main part showing a state of installation on an apparatus according to Embodiment 3 of the present invention. The same portions as those described in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Only different portions will be described.
[0070]
In FIG. 8, when the tank 44 is mounted on the oil receiving tray 43, the tank 44 is held on a wall different from the opening 42 of the tank housing 41 on the wall different from the opening 42 of the tank housing 41. The magnet 45 of the fixing means is disposed in such a manner.
[0071]
In the above configuration, since the magnet is disposed at an appropriate position on the wall different from the open portion 45 of the tank storage portion 41, when the tank 44 is mounted on the oil receiving tray 43, the tank 44 becomes the tank storage portion 41 of the device main body. Is held by magnetic force in a direction different from that of the open portion 42. With a simple configuration, there is no fear that the tank 44 falls down to the open portion 42 side for some reason such as vibration. There is no need to worry about the 44 being detached from the tank storage section 41, and the safety is increased. In addition, there is no need to detach the fixing means, and the tank 44 can be easily attached and detached.

FIG. 9 is a cross-sectional view of a main part showing an installation state of the apparatus according to the fourth embodiment of the present invention. The same portions as those described in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. Only different portions will be described.
[0073]
In FIG. 9, when the tank 52 is mounted on the oil receiving tray 51, the oil receiving tray 51 on the opening 54 side is held so that the tank 52 is tilted and held in a different direction from the opening 54 of the tank housing 53 of the device main body. The configuration is such that a projection 51a is provided on the upper surface.
[0074]
In the above-described configuration, the effect of the third embodiment is realized by another method. Since the protrusion 51a is provided on the upper surface of the oil pan 51 on the side of the open portion 54 which is the inclined holding means, the oil pan is provided. When the tank 52 is mounted on the tank 51, the tank 52 is tilted and held in a direction different from that of the open portion 54 of the tank storage portion 53 of the device main body. There is no need to worry about falling down, and there is no need to worry about the opening 52 being opened carelessly and the tank 52 detaching from the tank housing 53, thus increasing the safety. Attachment and detachment of 52 are also facilitated.
[0075]
In the above embodiment, a configuration in which the handle direction of the first handle 24 and the second handle 25 is orthogonal to each other, a configuration in which a partition plate 26 that partitions the upper space in the tank 11 so as to be orthogonal to the longitudinal direction, and The configuration in which the partition plate 26 is inclined and the configuration in which the second handle 25 is disposed on the surface of the oil amount window 12 for confirming the oil amount in the tank 11 have been described at the same time. The configuration in which the center of the second handle 33 is positioned farther from the center of gravity of the tank 31 than the first handle 32 and the configuration in which the second handle is inclined are described at the same time. The configuration is not limited to the configuration of the embodiment as long as the effect can be achieved.
