また、請求項２に記載の発明は、縦長筒型ストーブ本体の燃焼室の下方にロストルと底面に灰受け皿と前面に開閉戸とを設け、上面前方の開口部に開閉蓋を設け、上面後方に煙突を接合し、下面に脚を配設して成る薪焚きストーブにおいて、
前記燃焼室の左右側壁を貫通して設けたオーブンは、上面後方には換気レバーで開閉される排煙口を開口し、後部縦壁には給気口を開口し、両端の挿入口には給気路を開口した開閉蓋を被蓋し、燃焼室の後壁外面に遮熱チェンバを形成し、遮熱チェンバに配設した空気取り入れ口を燃焼室後壁の上部に開口した二次空気口に連通するとともに該後壁下方に開口した二次空気入口に連通し、前記後壁とオーブンの下面間を仕切る遮蔽板に連通口を開口し、該連通口をダンパーで開閉自在に閉塞し、ストーブ本体の上面後方に立設した調理釜の下方を仕切り金網を介して燃焼室に連通し、前記煙突が調理釜を介して立設され、該煙突口にダンパーを配設して成る。
さらに、請求項３に記載の発明は、請求項１又は２のストーブにおいて、ストーブの後壁とオーブン下面間の遮蔽板に設けた連通口を開閉し、燃焼火焔により排煙道の煤を燃焼させようとするものである。
【０００５】
【発明の実施の形態】
オーブンは内部が左右に貫通するものから仕切り壁を有するものがあり、煙突の遮熱構造では、目鏡に対する遮熱筒の接合がシール材を介してビス止めするものや溶接がある。
【０００６】
【実施例】
本発明の実施例を説明すると、図１、２、３に示す薪焚き調理ストーブＡは、ストーブ本体１の平面輪郭形状を図３（ｃ）に示すように、後方を丸形に前方を角形にした縦長筒型の胴体とし、その上下に該胴体の輪郭より大きいか同大の天板２と床板３が接合され、胴体の内部に調理燃焼室（以下、燃焼室とする。）４が形成されている。燃焼室４は下方には図３（ｂ）に示すように、長さ350ｍｍ、幅280ｍｍ、高さ30ｍｍで多数の灰抜き穴を貫設した波形のロストル５を配設し、底面には灰受け皿６を設け、上方の天板２には図３（ａ）に示すように、前方の開口部７に開閉蓋８を被蓋し、後方に立設した煙突口９に煙突１０を接合し、床板３の下面に脚１１を接合する。さらに、燃焼室４の上方には図３（ｂ）に示すように、胴体の左右の側壁１２を貫通して断面口型のオーブン１３を横設する。オーブン１３は上面後方には左右にスライドする換気レバー１４の蓋板１５で開閉される２個の排煙口１６を開口するとともに、胴体の側壁１２から突出した部分の縦壁１７に給気口１８を開口し、左右の挿入口には図１に示すように、僅かの隙間（給気路）を開けた開閉蓋１９を被蓋する。燃焼室４の後壁に対応する胴体の外面には図３（ａ）に示すように、遮熱チェンバ２０を形成する。遮熱チェンバ２０は下部に図２に示すように設けた空気取り入れ口２１を、燃焼室４の後壁の中部に図３（ｂ）に示すように開口した二次空気口２２に連通するとともに、後壁の下方に図３（ａ）に示すように開口した二次空気入口２３に連通させている。さらに、図３（ｂ）に示すように、後壁の内面からオーブン１３の下面に渡って仕切り状に接合した遮蔽板２４に連通口２５を開口し、連通口２５をダンパー２６で開閉自在に閉塞している。煙突口９にダンパー２７を配設し、ストーブ本体１の前面の焚き口２８には図１に示すように、片開きの開閉戸２９を設けて成っている。開閉戸２９には雲母製や耐熱ガラス製の透かし窓３０を設け、図３（ａ）に示すように、燃焼室４のロストル５の前面側に衝立板３１を立設して衝立板３１と透かし窓３０の内面間にエアーカーテンができる通気路３２を形成させている。このため初期燃焼時や不完全燃焼があっても煤が透かし窓３０内面に付着しない。
【０００７】
このようにして成る薪焚き調理ストーブＡは、図２に示すように、煙突口９に煙突１０が接合され、煙突１０の水平管３３が断熱構造Ｃ（後述する）を介して建屋の壁体３４に支持されて家庭用の暖房と各種材料の蒸焼き調理に使用される。
すなわち、燃料は木材であれば材種を問わないが現在は間伐材の有効利用がある。燃焼熱はストーブ本体１の側方から前方にかけて放熱され、後方の輻射熱は遮熱チェンバ２０の遮断によって建屋の壁体３４への加熱が防止される。そして、ガス・灯油・電気を用いないで暖房状態のままでオーブン１３により蒸焼き調理ができる。その際、オーブン１３は両挿入口の開閉蓋１９は閉じた状態で前記隙間の給気路と給気口１８の給気により、換気レバー１４を操作したときの排煙口１６からの排煙も換気も十分となる。
【０００８】
次に、図４、５、６、７、８に示す薪焚き調理ストーブＢにつき説明する。なお、前記薪焚き調理ストーブＡと同様の部分には同一の符号を付して説明する。ストーブ本体１の平面輪郭形状を図８に示すように、逆壷形にした縦長筒型の胴体とし、その上下に該胴体の輪郭より大きい相似形の天板２と床板３が接合され、胴体の内部に燃焼室４が形成され、燃焼室４の下方には図７に示すように、ロストル５を配設し、その下方に灰受け皿６を設け、上方の天板２には前方の２個所の開口部７にそれぞれ開閉蓋８を被蓋し、後方には燃焼室４に連通して調理釜３５（後述）を立設し、床板３に脚１１を接合する。さらに、燃焼室４の上方には胴体の左右の側壁１２を貫通して断面口型のオーブン１３を横設する。オーブン１３は上面後方には左右にスライドする換気レバー１４の蓋板１５で開閉される２個の排煙口１６を開口するとともに、胴体の側壁１２から突出した部分の縦壁１７には所要数の給気口１８を開口し、左右の挿入口には僅かの隙間（給気路）を開けた開閉蓋１９を被蓋する。燃焼室４の後壁に対応する胴体の外面には遮熱チェンバ２０を形成する。遮熱チェンバ２０に設けた空気取り入れ口２１を燃焼室４の上部に開口した二次空気口２２に連通するとともに、後壁の下方に開口した二次空気入口２３に連通させている。さらに、後壁の内面からオーブン１３の下面に渡って仕切り状に接合した遮蔽板２４に連通口２５を開口し、連通口２５をダンパー２６で開閉自在に閉塞し、ストーブ本体１の焚き口２８には図４に示すように、観音開きの開閉戸２９を設けて成っている。開閉戸２９には透かし窓３０を設け、燃焼室４のロストル５の前面側に衝立板３１が立設して通気路３２が形成される。
調理釜３５は図４に示すように、平面視楕円状の筒体で上部が絞られ、その前面の開口部に観音開きの開閉戸３６が蝶着され、その下方は図６に示すように、燃焼室４の上部に着脱自在に載置された仕切り金網３７を介して燃焼室４に連通し、その頂部には金網３８を接合するとともに、立設した煙突口９にはダンパー２７を配設して煙突１０を接合して成っている。
【０００９】
薪焚き調理ストーブＢは、図５に示すように、煙突１０の水平管３３が後述の断熱構造Ｃを介して建屋の壁体３４に支持されて家庭用の暖房と蒸焼き調理に使用され、調理釜３５では木炭を燃料として焼肉や焼鳥、焼魚などの焼き物が調理できる。この焼き物調理で魚肉から出る油は燃料の上に滴下するが、下方の燃焼室４の熱によって瞬時に燃焼するので燃料の火力が弱まったり料理が油臭くなることがない。このほか、桜材などを燃料として肉や魚などを内部に吊下し、開閉戸３６を閉じて燻すと薫製品が得られる。
【００１０】
断熱構造Ｃについて説明すると、ストーブ本体１の煙突口９、又は調理釜３５の煙突口９に接続する煙突１０は、図９、１０に示すように、水平管３３に所要の放熱空間３９を形成して遮熱筒４０が外嵌され、放熱空間３９を屋内と屋外に仕切る遮蔽板４１で気密状に塞ぎ、遮熱筒４０に気密にビス止めされた外形角形の目鏡４２を、遮熱筒４０の外周に十分な放熱空間を形成した角形の貫通口４３の周縁にビス止めして水平管３３が壁体３４に断熱状態で支持される。屋外の垂直管４４は支持体４５やステー４６によって支持される。
【００１１】
このようにして成る断熱構造Ｃによれば、水平管３３から放熱される輻射熱は遮熱筒４０の放熱空間３９によって遮熱され、遮熱筒４０と壁体３４の貫通口４３との間にも放熱空間４７が形成されるから、煤燃焼時の高温も十分に遮熱される。
【００１２】
ストーブ排煙路に付着する煤を燃焼して消失させるには、燃焼室４の後壁とオーブン１３の下面を仕切る遮蔽板２４に設けられた連通口２５をダンパー２６で開き燃焼室４後方に薪を立て掛けて燃焼させると、火煙は燃焼室内を迂回しないで煙突等に直接上昇してその火勢と熱で煤が燃焼し消失する。
【００１３】
【発明の効果】
請求項１に記載の発明によれば、調理燃焼室での薪燃焼による暖房とオーブンによる蒸焼き調理ができ、さらに、遮熱チェンバによって建屋の壁体側への輻射熱を遮熱し二次空気を予熱して燃焼室に供給するから燃焼効率を向上させることができる。
請求項２に記載の発明によれば、前記請求項１に記載の発明における効果のほか、調理燃焼室に連通する調理釜によって焼き物や薫製品を作ることができる。
請求項３に記載の発明によれば、ストーブ排煙路の煤を人手をかけることなく燃焼し消失させることができる。
