Description

【０００１】
【産業上の利用分野】
この発明は、芯上下式石油ストーブの放電式点火装置に関するものである。
【０００２】
【従来の技術】
従来よりこの種のものに於いては、例えば図８に示すように、スライド摘み１０１を押し下げることにより芯上げを行い、スライド摘み１０１を芯上げが完了する位置から更に押し下げることにより、点火用電池（図示せず）を電源とした放電電極（図示せず）による点火を行うものであった。
【０００３】
つまり消火時の位置にあるスライド摘み１０１を押し下げることにより、摘みレバー１０２が回動し、該摘みレバー１０２の先端部分と連結されている芯上下レバー１０３が回動して芯上下軸１０４を回動させ、それにより芯（図示せず）が上昇する。
【０００４】
又摘みレバー１０２と同軸に軸支されている回転板１０５の係止部１０６と摘みレバー１０２とが当接し、回転板１０５を元の位置に戻そうとする戻しバネ１０７に蓄力しながら回転板１０５を回動させる。
【０００５】
そして芯が上昇して最大燃焼位置に達するまで摘みレバー１０２を回動させた時、回転板１０５が耐震自動消火装置１０８のロック部１０９と係合して、戻しバネ１０７が蓄力した状態で回転板１０５を係止し、摘みレバー１０２もその位置で静止する。
【０００６】
その位置からスライド摘み１０１を更に押し下げると、摘みレバー１０２が係止部１０６と当接した状態で回動し、ロック部１０９と係合している回転板１０５を更に回動させながら、芯上下レバー１０３も回動させて、芯を最大燃焼位置から点火位置まで上昇させると共に、回転板１０５の当接部１１０が点火スイッチ１１１と当接し、それにより点火スイッチ１１１がオン状態となって放電点火装置（図示せず）が放電を行い、その放電火花により芯に着火させる。
【０００７】
着火後、スライド摘み１０１から手を離すと、戻しバネ１０７により回転板１０５が再度ロック部１０９と係合する位置まで逆方向に回動し、それにより回転板１０５の当接部１１０が点火スイッチ１１１から離れて、該点火スイッチ１１１がオフ状態となって放電点火装置が放電を停止すると共に、係止部１０６により摘みレバー１０２が逆方向に回動し、それにより芯上下レバー１０３が逆方向に回動して芯を点火位置から最大燃焼位置まで下降させる。
【０００８】
そしてその状態から火力調節するためにスライド摘み１０１を持ち上げると、摘みレバー１０２が逆方向に回動し、それにより芯上下レバー１０３が逆方向に回動して、スライド摘み１０１を持ち上げるのに対応して芯を最大燃焼位置から下降させて火力を小さくするものであった。
【０００９】
【発明が解決しようとする課題】
ところでこの従来のものでは、芯の上下動作と点火動作とがスライド摘みの上下操作により行われるため、火力を調節するためにスライド摘みを押し下げた時、勢い余って点火動作位置まで押し下げてしまったり、子供がいたずらして押し下げてしまった場合、着火しているにもかかわらず点火動作を行って点火用の電池の寿命を短くしてしまう欠点があった。
【００１０】
又消火状態で石油ストーブの周りに人がいない時や、シーズンオフに燃油を抜かずに点火用電池がセットされたままで石油ストーブをしまっている場合などに、物が落下して当たったり等何らかの原因でスライド摘みが押し下げられたりすると点火してしまう場合があった。
【００１１】
【問題点を解決するための手段】
本発明はこの点に着目し上記欠点を解決するため、特にその構成を、請求項１では、本体枠に設けた操作部に一端が突出し、芯を上下動させる芯上下機構と連結して芯の上下操作を行う摘みレバーと、該摘みレバーの突出した一端に取り付けるスライド摘みと、放電電極による芯への点火動作を行う点火スイッチとを備え、前記スライド摘みを操作することにより芯の上下操作を行い、前記点火スイッチを操作することにより点火動作を行う石油ストーブの放電式点火装置において、前記点火スイッチはスライド摘みと一体に形成されると共に、芯が点火位置に達するまでスライド摘みを操作した時、点火スイッチを操作すると点火動作を行うと共に、芯が点火位置に達しいないところまでスライド摘みを操作した時、点火スイッチを操作しても点火動作を行わない誤点火防止手段を点火スイッチに設けたものである。
【００１２】
又本発明の請求項２に係る石油ストーブの放電式点火装置では、本体枠に設けた操作部に一端が突出し、芯を上下動させる芯上下機構と連結して芯の上下操作を行う摘みレバーと、該摘みレバーの突出した一端に取り付けるスライド摘みと、放電電極による芯への点火動作を行う点火スイッチとを備え、前記スライド摘みを操作することにより芯の上下操作と点火操作とを行う石油ストーブの放電式点火装置において、前記スライド摘みをスライドさせることにより芯の上下操作を行い、スライド摘みが押し込まれた時点火スイッチが点火動作を行うと共に、芯が点火位置に達していないときはスライド摘みが押し込まれても点火スイッチを常にオフ状態とする誤点火防止手段を設け、前記スライド摘みは、芯の上下操作時に摘む摘み部と、点火操作時に押し込む点火部とからなり、点火操作時に押し込まれた点火部が当接してオン状態となる点火スイッチを摘みレバーの一端部分に取り付け、前記点火部には、点火部が押し込まれないように点火部背面に防止片を設けると共に、芯が点火位置に達している状態では点火部が押し込めるように防止片に対向する操作部部分に点火用溝を設け、該点火用溝と防止片とにより誤点火防止手段を構成したものである。
【００１３】
又本発明の請求項３に係る石油ストーブの放電式点火装置では、本体枠に設けた操作部に一端が突出し、芯を上下動させる芯上下機構と連結して芯の上下操作を行う摘みレバーと、該摘みレバーの突出した一端に取り付けるスライド摘みと、放電電極による芯への点火動作を行う点火スイッチとを備え、前記スライド摘みを操作することにより芯の上下操作と点火操作とを行う石油ストーブの放電式点火装置において、前記スライド摘みをスライドさせることにより芯の上下操作を行い、スライド摘みが押し込まれた時点火スイッチが点火動作を行うと共に、芯が点火位置に達していないときはスライド摘みが押し込まれても点火スイッチを常にオフ状態とする誤点火防止手段を設け、前記スライド摘みは、芯の上下操作時に摘む摘み部と、点火操作時に押し込む点火部からなり、前記点火スイッチは、芯が点火位置に達するようにスライド摘みをスライドさせた状態で押し込まれる点火部に当接してオン状態となる第１スイッチと、芯が点火位置に達するようにスライド摘みをスライドさせた時摘みレバーと当接してオン状態となる第２スイッチとからなり、前記誤点火防止手段は第１スイッチと第２スイッチとが両方オン状態となったときのみ点火スイッチに点火動作を行わせるものである。
【００１４】
【作用】
上記の構成により、スライド摘み２０の上下操作では芯の上下動作のみを行い、スライド摘み２０を押し下げて芯が点火位置に達した状態でスライド摘み２０の点火部２４を押し込む操作により点火動作を行うので、スライド摘み２０の上下操作中に誤って点火動作を行うことを防止でき、それにより点火用電池の寿命が短くなるのを防止でき、また、物が落下して当たったり等何らかの原因でスライド摘み２０が下まで押し下げられても、更に押し込まれなければ点火動作しないので極めて安全である。
【００１５】
又芯が点火位置に位置していない状態、つまりスライド摘み２０が下まで押し下げられていない状態でスライド摘み２０の点火部２４を押し込んでも、点火スイッチ１４はオフ状態のままで点火動作は行わないので、子供等のいたずらによる点火動作を防止できるものである。
【００１６】
【実施例】
次に、この発明に係る石油ストーブの放電式点火装置を図面に示された一実施例で説明する。
１は前面上部を開放し内方には燃油タンク（図示せず）や燃焼部（図示せず）を収納した本体枠で、前面下部を取り外し自在な前面板２により構成している。
前記前面板２の中央やや右よりの開口部３にはパネル状に形成されたプラスチックの操作部４が嵌合されている。
【００１７】
５は本体枠１の前面上部開放部分に備えられた燃焼筒で、その周りを熱が反射する反射板６で囲んでいる。
【００１８】
７は操作部４に設けられた凹部で、該凹部７内の正面部分には断面円弧状の円弧部８が形成され、更に該円弧部８の中央部分には上下方向に長孔上のスライド孔９が形成されているものである。
【００１９】
更に前記スライド孔９を中心にして円弧部８下方の左右には、点火用溝１０、１１が形成されているものである。
【００２０】
１２は摘みレバーで、その一端が突出部１３として本体枠１内から操作部４の凹部７のスライド孔９を貫通して凹部７内に突出し、他端が本体枠１内に収納された燃焼部の芯上下機構（図示せず）と連結しており、摘みレバー１２が回動することにより芯（図示せず）が上下に動作するものである。
【００２１】
１４は摘みレバー１２の突出部１３のやや他端よりに設けた点火スイッチで、信号線１５、１６により点火回路（図示せず）と接続されているスイッチ端子１７、１８と、該両スイッチ端子１７、１８と接触することにより点火スイッチ１４をオン状態とする断面Ｌ字状のスイッチ片１９が設けられている。
【００２２】
２０は断面Ｌ字状のスライド摘みで、芯を上下動させるために摘みレバー１２をスライドさせる時、例えば上下動させる時に摘む摘み部２１と、背面に誤点火を防止するための防止片２２、２３を設け点火動作する際に指により押し込まれる点火部２４とからなり、操作部４の凹部７内に突出する摘みレバー１２の突出部１３先端に取り付けられるものである。
【００２３】
そして摘みレバー１２の突出部１３先端にスライド摘み２０を取り付けた時、点火部２４の背面にある防止片２２、２３間に両スイッチ端子１７、１８と接触しない状態でスイッチ片１９が位置するようになっている。
【００２４】
２５は操作部４に設けた消火ボタンで、押し込むことにより燃焼部の耐震自動消火装置（図示せず）を作動させて瞬時に芯を消火位置まで下降させることにより消火を行うものである。
【００２５】
次にこの実施例の作動について説明する。
まず消火状態から点火操作するときは、図３のように、消火時には摘みレバー１２が戻しバネ（図示せず）により引っ張られて、スライド摘み２０がスライド孔９の上方に位置しているので、そのスライド摘み２０の摘み部２１を指で押し下げてスライドさせることにより、摘みレバー１２が回動して芯が上昇する。
【００２６】
この時、誤ってスライド摘み２０の点火部２４を押し込もうとしても、点火部２４の背面にある防止片２２、２３が、凹部７の円弧部８に当接して押し込まれず、スイッチ片１９がスイッチ端子１７、１８と接触することはなく、点火スイッチ１４はオフ状態のままで点火動作は行われない。
【００２７】
そして図４のように、芯が上昇して点火位置に達するまでスライド摘み２０を押し下げると、芯を点火位置に保持する保持機構（図示せず）により芯が点火位置に保持されると共に、摘みレバー１２もその位置に静止する。
【００２８】
この時、点火部２４背面の防止片２２、２３は、円弧部８の点火用溝１０、１１のところに位置しており、ここでスライド摘み２０の点火部２４を押し込むと、点火部２４は防止片２２、２３が点火用溝１０、１１の溝部分に当接するまで後方に傾斜する。
【００２９】
それにより、点火スイッチ１４のスイッチ片１９が点火部２４背面に押されてスイッチ端子１７、１８と当接し、点火スイッチ１４がオン状態となって放電電極（図示せず）による点火動作が行われ、その放電火花により芯が着火する。
【００３０】
そして、着火後、点火部２４から指を離すと、押し込まれて後方に傾斜していた点火部２４は、点火部２４自身の弾性により元の角度まで復帰し、それにより点火部２４の背面に押されていたスイッチ片１９も、スイッチ片１９自身の弾性により元の角度まで復帰してスイッチ端子１７、１８と離れ、点火スイッチ１４はオフ状態となって点火動作が終了する。
【００３１】
そして、その状態からスライド摘み２０を押し上げることにより芯が点火位置から下降し、石油ストーブの火力を最大の状態から任意の火力に調整できるものである。
【００３２】
このように、スライド摘み２０の上下操作は芯の上下動作、スライド摘み２０の点火部２４の押し込み操作は点火動作というように、スライド摘み２０を操作するのであっても芯の上下動作と点火動作とは異なる操作なので、芯の上下動作中、つまりスライド摘み２０の上下操作中に誤って点火動作を行ってしまうことがなく、芯の上下操作中の誤操作による点火動作での点火用電池の消耗を防止でき、また、物が落下して当たったり等何らかの原因でスライド摘み２０が下まで押し下げられても、更に押し込まれなければ点火動作しないので極めて安全である。
【００３３】
更にスライド摘み２０を押し下げて芯が点火位置まで上昇したとき、点火部２４が押し込めるようになっている、つまり点火動作ができるようになっているので、芯が点火位置にない状態では点火動作できず、防止片２２、２３と点火用溝１０、１１とにより誤点火防止手段を構成して、子供などのいたずらによる点火用電池の消耗を防止できるものである。
【００３４】
次にこの発明に係るその他の実施例について説明する。
前記本実施例と異なる点は、図５、図６、図７に示すように、摘みレバー１２に係合片２６を設け、スライド摘み２０を下まで押し下げて、芯が点火位置まで上昇した時の点火部２４背面のやや端の部分に対向するように、スイッチ片２７を円弧部８下方のスライド孔９の横の部分に突出させた第１スイッチ２８と、スライド摘み２０を下まで押し下げて芯が点火位置まで上昇した時、スイッチ片２９が係合片２６により押圧されてオン状態となる第２スイッチ３０とにより点火スイッチ１４を構成し、又スライド摘み２０の点火部２４背面には、防止片２２、２３がなく、円弧部８には点火用溝１０、１１が形成されていない点である。
【００３５】
次にその他の実施例の作動について説明する。
まず消火状態から点火操作するときは、図５及び図６のように、消火時には摘みレバー１２が戻しバネ（図示せず）により引っ張られて、スライド摘み２０がスライド孔９の上方に位置しているので、そのスライド摘み２０の摘み部２１を指で押し下げてスライドさせることにより、摘みレバー１２が回動して芯が上昇する。
【００３６】
この時、誤ってスライド摘み２０の点火部２４を押し込んでも、後方に傾斜した点火部２４の背面には第１スイッチ２８のスイッチ片２７が位置していないので、当然第１スイッチ２８はオフ状態のままであり、したがって点火動作は行われない。
【００３７】
そして図７のように、芯が上昇して点火位置に達するまでスライド摘み２０を押し下げると、芯を点火位置に保持する保持機構（図示せず）により芯が点火位置に保持されると共に、摘みレバー１２もその位置に静止する。
この時、第２スイッチ３０のスイッチ片２９は摘みレバー１２の係合片２６により押圧され、第２スイッチ３０はオン状態となるが、まだ点火動作は行われない。
【００３８】
そしてこの時、スライド摘み２０の点火部２４を押し込むと、点火部２４が後方に傾斜してその背面が第１スイッチ２８のスイッチ片２７に当接し、第１スイッチ２８もオン状態となって放電電極による点火動作が行われる。
【００３９】
つまり、第１スイッチ２８及び第２スイッチ３０の両方がオン状態になることによって、点火スイッチ１４がオン状態となって放電電極による点火動作が行われ、その放電火花により芯が着火するものである。
【００４０】
そして、着火後、点火部２４から指を離すと、押し込まれて後方に傾斜していた点火部２４は、点火部２４自身の弾性により第１スイッチ２８のスイッチ片２７から離れて元の角度まで復帰して第１スイッチ２８がオフ状態となり、それにより点火スイッチ１４はオフ状態となって点火動作が終了する。
【００４１】
そして、その状態からスライド摘み２０を押し上げることにより、係合片２６がスイッチ片２９から離れて第２スイッチ３０もオフ状態になると共に、芯が点火位置から下降し、石油ストーブの火力を最大の状態から任意の火力に調整できるものである。
【００４２】
このように、スライド摘み２０の上下操作は芯の上下動作、スライド摘み２０の点火部２４の押し込み操作は点火動作というように、スライド摘み２０をを操作するのであっても芯の上下動作と点火動作とは異なる操作なので、芯の上下動作中、つまりスライド摘み２０の上下操作中に誤って点火動作を行ってしまうことがなく、芯の上下操作中の誤操作による点火動作での点火用電池の消耗を防止でき、また、物が落下して当たったり等何らかの原因でスライド摘み２０が下まで押し下げられても、更に押し込まれなければ点火動作しないので極めて安全である。
【００４３】
更にスライド摘み２０が下まで押し下げ切られていない状態、つまり芯が点火位置まで達していない状態の時に、円弧部８から突出している第１スイッチ２８のスイッチ片２７を指などで押して第１スイッチ２８をオン状態にしても、スイッチ片２９が本体枠１内に位置していたずらできない第２スイッチ３０がオフ状態なので、点火スイッチ１４はオフ状態のままで点火動作をできず、第１スイッチ２８と第２スイッチ３０とにより誤点火防止手段を構成して、子供などのいたずらによる点火用電池の消耗を防止できるものである。
【００４４】
尚、本実施例ではスライド摘み２０を上下方向にスライドさせることにより芯の上下動作を行うがこれに限定されず、スライド摘み２０を左右方向にスライドさせることにより芯の上下動作を行うようにしてもよい。
【００４５】
また、摘みレバー１２の一端を操作部４の凹部７内に突出させ、その先端にスライド摘み２０を取り付けて、凹部７内にスライド摘み２０が位置するようにしたがこれに限定されず、本体枠１前面に摘みレバー１２の一端を突出させ、その先端にスライド摘み２０を取り付けて、スライド摘み２０を本体枠１前面に露出するように設けてもよい。
【００４６】
【発明の効果】
以上のようにこの発明によれば、芯の上下動作と点火動作とを一つのスライド摘みを操作することででき、しかも芯の上下動作はスライド摘みの上下操作により行い、点火動作はスライド摘みの押し込み操作により行うので、スライド摘みの上下操作により誤って点火動作を行うことがなく、芯の上下操作中の誤操作による点火動作での点火用電池の消耗を防止でき、また、物が落下して当たったり等何らかの原因でスライド摘みが下まで押し下げられても、更に押し込まれなければ点火動作しないので極めて安全である。
【００４７】
更に芯が点火位置まで達している状態、つまりそうなる位置までスライド摘みを押し下げた時に点火動作ができるようにしたので、芯が点火位置まで達していない状態、つまり点火動作を行う意思がない状態での点火動作は行わないので、子供などのいたずらによる点火用電池の消耗も防止できるものである。

[Industrial application fields]
The present invention relates to a discharge igniter for a vertical core type oil stove.
[0002]
[Prior art]
Conventionally, in this type of battery, as shown in FIG. 8, for example, the slide knob 101 is pushed down to raise the center, and the slide knob 101 is further pushed down from the position where the centering is completed. Ignition was performed by a discharge electrode (not shown) using a power source (not shown) as a power source.
[0003]
That is, by depressing the slide knob 101 at the fire extinguishing position, the knob lever 102 rotates, and the core up / down lever 103 connected to the tip of the knob lever 102 rotates to rotate the core vertical axis 104. Causing the lead (not shown) to rise.
[0004]
Further, the latching portion 106 of the rotary plate 105 that is pivotally supported coaxially with the knob lever 102 is in contact with the knob lever 102 and rotates while accumulating in the return spring 107 that attempts to return the rotary plate 105 to its original position. The plate 105 is rotated.
[0005]
When the knob lever 102 is rotated until the lead rises and reaches the maximum combustion position, the rotating plate 105 is engaged with the lock portion 109 of the earthquake-proof automatic fire extinguishing device 108 and the return spring 107 is accumulated. The rotary plate 105 is locked, and the knob lever 102 is also stopped at that position.
[0006]
When the slide knob 101 is further pushed down from that position, the knob lever 102 rotates in a state of being in contact with the locking portion 106, and the rotary plate 105 engaged with the lock portion 109 is further rotated while moving the core up and down. The lever 103 is also rotated to raise the lead from the maximum combustion position to the ignition position, and the contact portion 110 of the rotating plate 105 contacts the ignition switch 111, whereby the ignition switch 111 is turned on and discharge ignition. A device (not shown) discharges and ignites the core by the discharge spark.
[0007]
After the ignition, when the hand is released from the slide knob 101, the return spring 107 rotates the rotating plate 105 in the opposite direction to the position where the rotating plate 105 is engaged with the lock portion 109 again, whereby the contact portion 110 of the rotating plate 105 is turned on by the ignition switch. In this state, the ignition switch 111 is turned off and the discharge ignition device stops discharging, and the latch lever 102 is rotated in the reverse direction by the locking portion 106, whereby the core up / down lever 103 is moved in the reverse direction. And the wick is lowered from the ignition position to the maximum combustion position.
[0008]
When the slide knob 101 is lifted to adjust the heating power from that state, the knob lever 102 is rotated in the reverse direction, whereby the core up / down lever 103 is rotated in the reverse direction to cope with the lifting of the slide knob 101. The core is lowered from the maximum combustion position to reduce the thermal power.
[0009]
[Problems to be solved by the invention]
By the way, in this conventional type, the up / down movement of the lead and the ignition operation are performed by the up / down operation of the slide knob. When the child has mischievously pushed it down, there is a drawback in that the ignition operation is performed despite the ignition and the life of the ignition battery is shortened.
[0010]
Also, when there are no people around the oil stove in the fire extinguisher, or when the oil stove is set off with the ignition battery set without draining the fuel off the season, etc. When the slide knob was pushed down for some reason, it could ignite.
[0011]
[Means for solving problems]
The present invention pays attention to this point and solves the above-described drawbacks. In particular, in the present invention, in claim 1, one end protrudes from the operation portion provided on the main body frame and is connected to a core up-and-down mechanism that moves the core up and down. A pick lever that performs an up / down operation, a slide pick attached to one end of the pick lever that protrudes, and an ignition switch that performs an ignition operation on the lead by the discharge electrode. In the discharge type ignition device of the oil stove that performs the ignition operation by operating the ignition switch , the ignition switch is formed integrally with the slide knob, and the slide knob is operated until the lead reaches the ignition position. When the ignition switch is operated, the ignition operation is performed, and when the slide knob is operated until the lead does not reach the ignition position, the ignition switch is operated. Is also intended to ignition preventing means erroneously not performed an ignition operation is provided in the ignition switch.
[0012]
Further, in the discharge type ignition device for an oil stove according to claim 2 of the present invention, a knob lever that moves up and down the core by one end projecting from an operating portion provided on the main body frame and connected to a core vertical mechanism that moves the core up and down. And a slide knob attached to the protruding end of the knob, and an ignition switch for igniting the core by the discharge electrode, and operating the slide knob to perform the vertical operation and ignition operation of the core. In the discharge type ignition device of the stove, the wick is moved up and down by sliding the slide knob. When the slide knob is pushed in, the fire switch performs an ignition operation and slides when the wick does not reach the ignition position. even knob is pushed provided an ignition preventing means erroneous and always off the ignition switch, the slide knob, and the knob portion pinching during vertical operation of the core, An ignition switch that is pushed in at the time of a fire operation, and an ignition switch that comes into contact with the ignition part that is pushed in at the time of the ignition operation is attached to one end portion of a knob so that the ignition part is not pushed into the ignition part In the state where the prevention part is provided on the back of the ignition part, an ignition groove is provided in the operation part facing the prevention part so that the ignition part can be pushed in when the lead reaches the ignition position. This constitutes a false ignition prevention means.
[0013]
Further, in the discharge type ignition device for a petroleum stove according to the third aspect of the present invention, a knob lever that moves up and down the core by one end projecting from an operating portion provided on the main body frame and connected to a core vertical mechanism that moves the core up and down. And a slide knob attached to the protruding end of the knob, and an ignition switch for igniting the core by the discharge electrode, and operating the slide knob to perform the vertical operation and ignition operation of the core. In the discharge type ignition device of the stove, the wick is moved up and down by sliding the slide knob. When the slide knob is pushed in, the fire switch performs an ignition operation and slides when the wick does not reach the ignition position. even knob is pushed provided an ignition preventing means erroneous and always off the ignition switch, the slide knob, and the knob portion pinching during vertical operation of the core, The ignition switch is pushed in at the time of a fire operation. The ignition switch is in contact with the ignition part pushed in with the slide knob being slid so that the lead reaches the ignition position, and the lead is ignited. When the slide knob is slid so as to reach the position, it comprises a second switch that comes into contact with the knob lever and is turned on, and the erroneous ignition prevention means has both the first switch and the second switch turned on. Only when the ignition switch is ignited.
[0014]
[Action]
With the above configuration, the up / down operation of the slide knob 20 performs only the up / down movement of the core, and the ignition operation is performed by pushing down the slide knob 20 and pushing the ignition unit 24 of the slide knob 20 in a state where the core reaches the ignition position. Therefore, it is possible to prevent the ignition operation from being erroneously performed during the up / down operation of the slide knob 20, thereby preventing the life of the ignition battery from being shortened, and to slide the object due to something falling or hitting it. Even if the knob 20 is pushed down, the ignition operation is not performed unless the knob 20 is further pushed down, which is extremely safe.
[0015]
Further, even if the ignition part 24 of the slide knob 20 is pushed in the state where the lead is not positioned at the ignition position, that is, the slide knob 20 is not pushed down, the ignition switch 14 remains in the off state and the ignition operation is not performed. Therefore, it is possible to prevent an ignition operation caused by mischief of children or the like.
[0016]

Further, ignition grooves 10 and 11 are formed on the left and right sides of the arc portion 8 with the slide hole 9 as the center.
[0020]
Reference numeral 12 denotes a knob lever, one end of which is a protruding portion 13 which penetrates the slide hole 9 of the concave portion 7 of the operation portion 4 from the inside of the main body frame 1 and protrudes into the concave portion 7, and the other end is a combustion housed in the main body frame 1. It is connected to a core up / down mechanism (not shown), and the lead (not shown) moves up and down when the knob lever 12 rotates.
[0021]
14 is an ignition switch provided at the slightly other end of the protruding portion 13 of the knob lever 12, switch terminals 17 and 18 connected to an ignition circuit (not shown) by signal lines 15 and 16, and both switch terminals. A switch piece 19 having an L-shaped cross section is provided to bring the ignition switch 14 into an ON state by contact with 17 and 18.
[0022]
Reference numeral 20 denotes a slide knob having an L-shaped cross section. When the knob lever 12 is slid to move the core up and down, for example, a knob part 21 to be picked when the knob is moved up and down, and a prevention piece 22 to prevent mis-ignition on the back surface. 23 is provided with an ignition part 24 that is pushed by a finger when an ignition operation is performed, and is attached to the tip of the protrusion 13 of the knob 12 that protrudes into the recess 7 of the operation part 4.
[0023]
When the slide knob 20 is attached to the tip of the protrusion 13 of the knob 12, the switch piece 19 is positioned between the prevention pieces 22 and 23 on the back of the ignition part 24 without contacting the switch terminals 17 and 18. It has become.
[0024]
Reference numeral 25 denotes a fire extinguishing button provided on the operation unit 4 to operate the seismic automatic fire extinguishing device (not shown) of the combustion unit by pushing it in and to extinguish the fire by instantaneously lowering the core to the fire extinguishing position.
[0025]
Next, the operation of this embodiment will be described.
First, when the ignition operation is performed from the fire extinguishing state, as shown in FIG. 3, since the knob 12 is pulled by a return spring (not shown) and the slide knob 20 is positioned above the slide hole 9 as shown in FIG. By pushing down and sliding the knob portion 21 of the slide knob 20 with the finger, the knob lever 12 rotates and the lead rises.
[0026]
At this time, even if the ignition part 24 of the slide knob 20 is accidentally pushed in, the prevention pieces 22 and 23 on the back surface of the ignition part 24 are not pushed in contact with the arc part 8 of the recess 7 and the switch piece 19 is not pushed. There is no contact with the switch terminals 17 and 18, and the ignition switch 14 remains off and no ignition operation is performed.
[0027]
Then, as shown in FIG. 4, when the slide knob 20 is pushed down until the lead rises to the ignition position, the lead is held at the ignition position by a holding mechanism (not shown) that holds the lead in the ignition position. The lever 12 also stops at that position.
[0028]
At this time, the prevention pieces 22 and 23 on the back surface of the ignition part 24 are located at the ignition grooves 10 and 11 of the arc part 8. When the ignition part 24 of the slide knob 20 is pushed in here, the ignition part 24 is The prevention pieces 22 and 23 are inclined rearward until they come into contact with the groove portions of the ignition grooves 10 and 11.
[0029]
As a result, the switch piece 19 of the ignition switch 14 is pushed to the back of the ignition unit 24 and comes into contact with the switch terminals 17 and 18, the ignition switch 14 is turned on, and an ignition operation is performed by a discharge electrode (not shown). The core is ignited by the discharge spark.
[0030]
Then, after ignition, when the finger is released from the ignition unit 24, the ignition unit 24 that has been pushed and inclined backward is restored to the original angle by the elasticity of the ignition unit 24 itself, and thereby the back of the ignition unit 24 The pressed switch piece 19 also returns to its original angle by the elasticity of the switch piece 19 itself and is separated from the switch terminals 17 and 18, and the ignition switch 14 is turned off and the ignition operation is finished.
[0031]
Then, by pushing up the slide knob 20 from this state, the lead is lowered from the ignition position, and the heating power of the oil stove can be adjusted from the maximum state to an arbitrary heating power.
[0032]
Thus, even if the slide knob 20 is operated, the vertical operation of the slide knob 20 is an up / down operation of the lead, and the pushing operation of the ignition unit 24 of the slide knob 20 is an ignition operation. Therefore, the ignition battery is not accidentally ignited during the up / down movement of the lead, that is, during the up / down operation of the slide knob 20, and the ignition battery is consumed by the ignition operation due to the wrong operation during the up / down operation of the lead. In addition, even if the slide knob 20 is pushed down for some reason, such as when an object falls and hits it, the ignition operation is not performed unless the slide knob 20 is further pushed down, which is extremely safe.
[0033]
Further, when the slide knob 20 is pushed down and the lead rises to the ignition position, the ignition unit 24 can be pushed in, that is, the ignition operation can be performed. Therefore, the ignition operation can be performed when the lead is not in the ignition position. First, the prevention pieces 22 and 23 and the ignition grooves 10 and 11 constitute an erroneous ignition prevention means, which can prevent the ignition battery from being consumed due to mischief by a child or the like.
[0034]
Next, another embodiment according to the present invention will be described.
The difference from the present embodiment is that, as shown in FIGS. 5, 6, and 7, when an engagement piece 26 is provided on the knob lever 12 and the slide knob 20 is pushed down to raise the lead to the ignition position. The first switch 28 in which the switch piece 27 protrudes to the side portion of the slide hole 9 below the arc portion 8 and the slide knob 20 are pushed down so as to face the slightly end portion on the back side of the ignition portion 24 When the lead is raised to the ignition position, the switch piece 29 is pressed by the engagement piece 26 to be turned on to constitute the ignition switch 14, and on the back of the ignition part 24 of the slide knob 20, The prevention pieces 22 and 23 are not provided, and the ignition grooves 10 and 11 are not formed in the arc portion 8.
[0035]
Next, the operation of other embodiments will be described.
First, when the ignition operation is performed from the fire extinguishing state, as shown in FIGS. 5 and 6, the knob lever 12 is pulled by a return spring (not shown) during the fire extinguishing, and the slide knob 20 is positioned above the slide hole 9. Therefore, when the knob 21 of the slide knob 20 is pushed down and slid, the knob lever 12 rotates and the lead rises.
[0036]
At this time, even if the ignition part 24 of the slide knob 20 is accidentally pushed in, the switch piece 27 of the first switch 28 is not positioned on the back of the ignition part 24 inclined rearward. Therefore, the ignition operation is not performed.
[0037]
Then, as shown in FIG. 7, when the slide knob 20 is depressed until the lead rises to the ignition position, the lead is held at the ignition position by a holding mechanism (not shown) that holds the lead at the ignition position. The lever 12 also stops at that position.
At this time, the switch piece 29 of the second switch 30 is pressed by the engagement piece 26 of the knob lever 12, and the second switch 30 is turned on, but the ignition operation is not yet performed.
[0038]
At this time, when the ignition part 24 of the slide knob 20 is pushed in, the ignition part 24 inclines rearward and the back surface comes into contact with the switch piece 27 of the first switch 28, and the first switch 28 is also turned on and discharged. Ignition operation by the electrode is performed.
[0039]
That is, when both the first switch 28 and the second switch 30 are turned on, the ignition switch 14 is turned on and the ignition operation is performed by the discharge electrode, and the core is ignited by the discharge spark. .
[0040]
When the finger is released from the ignition unit 24 after ignition, the ignition unit 24 that has been pushed and inclined backward is separated from the switch piece 27 of the first switch 28 to the original angle by the elasticity of the ignition unit 24 itself. The first switch 28 is turned off and the ignition switch 14 is turned off to complete the ignition operation.
[0041]
Then, by pushing up the slide knob 20 from this state, the engagement piece 26 is separated from the switch piece 29 and the second switch 30 is also turned off, and the lead is lowered from the ignition position, so that the heating power of the oil stove is maximized. It can be adjusted to any firepower from the state.
[0042]
Thus, even if the slide knob 20 is operated, the vertical operation of the slide knob 20 is an up / down operation of the core, and the pushing operation of the ignition unit 24 of the slide knob 20 is an ignition operation. Since the operation is different from the operation, the ignition operation is not erroneously performed during the vertical movement of the lead, that is, during the vertical operation of the slide knob 20, and the ignition battery in the ignition operation due to the erroneous operation during the vertical movement of the lead It is possible to prevent wear, and even if the slide knob 20 is pushed down for some reason, such as when an object falls and hits it, it is extremely safe because it will not ignite unless it is pushed further down.
[0043]
Further, when the slide knob 20 is not pushed down all the way down, that is, when the lead does not reach the ignition position, the switch piece 27 of the first switch 28 protruding from the arc portion 8 is pushed with a finger or the like, and the first switch Even if the switch 28 is turned on, the switch piece 29 is located in the main body frame 1 and the second switch 30 that cannot be misplaced is in the off state. Therefore, the ignition switch 14 remains in the off state and the ignition operation cannot be performed. And the second switch 30 constitute a mis-ignition prevention means to prevent the ignition battery from being consumed due to mischief of a child or the like.
[0044]
In this embodiment, the vertical movement of the core is performed by sliding the slide knob 20 in the vertical direction, but the present invention is not limited to this, and the vertical movement of the core is performed by sliding the slide knob 20 in the horizontal direction. Also good.
[0045]
Further, one end of the knob lever 12 is protruded into the recess 7 of the operation unit 4 and a slide knob 20 is attached to the tip thereof so that the slide knob 20 is positioned in the recess 7. However, the present invention is not limited to this. One end of the knob 12 may be protruded from the front surface of the frame 1 and a slide knob 20 may be attached to the tip of the knob 1 so that the slide knob 20 is exposed to the front surface of the main body frame 1.
[0046]
【The invention's effect】
As described above, according to the present invention, the vertical movement of the lead and the ignition operation can be performed by operating one slide knob, and the vertical movement of the lead is performed by the vertical operation of the slide knob, and the ignition operation is performed by the slide knob. Since the operation is performed by pushing in, there is no accidental ignition operation due to the up / down operation of the slide knob, and it is possible to prevent the ignition battery from being consumed due to an erroneous operation during the up / down operation of the lead. Even if the slide knob is pushed down for some reason such as hitting it, it is extremely safe because it will not ignite unless it is pushed further down.
[0047]
Furthermore, since the lead has reached the ignition position, that is, the ignition operation can be performed when the slide knob is pushed down to such a position, the lead has not reached the ignition position, that is, there is no intention to perform the ignition operation. Since the ignition operation is not performed, it is possible to prevent consumption of the ignition battery due to mischief by a child or the like.
