ところが、このような従来の薪ストーブでは、未燃焼ガスを二次燃焼させて、排気ガスをクリーンにしているが、上方に二次燃焼室を設けこれに触媒を備えているので、構造が複雑で部品コストも高く、製造コストが高くなっているという問題がある。 However, in such a conventional wood-burning stove, and the unburned gas is secondary combustion, although the exhaust gas clean, is provided with the A catalytic provided secondary combustion chamber upwardly, complicated structure in parts cost is also high, there is a problem that the production cost is high. また、傾斜空気供給管による方法は、空気の吸い込みに対する条件が臨界的である。 Moreover, the method according to the inclined air supply pipe, conditions for suction of air is critical.
この発明は上記の問題点に鑑みてなされたもので、触媒を使用することなく、二次燃焼室に未燃焼ガスを滞留させて高温に保ち、そこに外部から充分な空気を供給することによって未燃焼ガスを効率的に燃焼させ、高効率の暖房効果を得ると同時に排気の黒煙を低減させ、市街地でも使えるような薪ストーブを提供することを目的とする。 The present invention has been made in view of the above problems, without the use of catalysts, allowed to stay unburned gases in the secondary combustion chamber maintained at a high temperature, there by providing sufficient air from the outside unburnt gas effectively burned, to reduce the black smoke of the exhaust and simultaneously obtain a heating effect of high efficiency, and to provide a wood stove as can also be used in urban areas.

このような目的を達成するため、この発明の薪ストーブは、薪が入れられる燃焼室を構成する本体と、上記本体に設けられ薪が投入される薪投入口と、上記本体に設けられ燃焼室に連通する二次燃焼筒とさらにこの二次燃焼筒に連通する煙突とを備えた薪ストーブにおいて、上記燃焼室内に薪が載置される載置部を設け、載置部は薪投入口の空気量調整弁から流入する空気を取り込む水平空気供給管を備え、水平空気供給管は薪投入口の反対方向の両側面に複数個の空気孔を備え、さらに、載置部の薪投入口とは反対側の燃焼室の上側に二次燃焼筒を設け、二次燃焼筒は横方向から外気空気量を調整して供給できる複数個の空気量調整管を有し、空気量調整管の取り付け位置より下部の二次燃焼筒には連結板が、空気量調整管の取り付け位置 To achieve the above object, a wood stove of the present invention includes a main body constituting the combustion chamber of wood is placed, a firewood inlet of firewood provided on the main body is turned on, the combustion chamber provided in the body in the wood stove with a chimney communicating with the secondary combustion tube and further the secondary combustion tube communicating the mounting portion provided firewood to the combustion chamber is mounted, placing portion of firewood inlet It comprises a horizontal air supply pipe to take the air flowing from the air amount adjusting valve, and the horizontal air supply pipe is provided with a plurality of air holes on both sides in the opposite direction of the wood inlet, addition, firewood inlet mounting portion is provided secondary combustion cylinder to the upper opposite side of the combustion chamber, the secondary combustion cylinder has a plurality of the air control pipe can be supplied from a lateral direction to adjust the fresh air amount of air, the mounting of the air control pipe connecting plate at the bottom of the secondary combustion cylinder than the position is, the mounting position of the air control pipe り上部の二次燃焼筒には対流抑止板を備え、二つの板の間に二次燃焼室を構成し、さらに対流抑止板の上方の空間である排気室の壁にはこの二次燃焼室の排気ガスを煙突に効率的に引き出す渦流形成翼が構成される。 Ri comprises a convection suppression plate in the secondary combustion cylinder at the top, constitute the secondary combustion chamber into two plates, the wall of the exhaust chamber is further space above the convection suppressing plate exhaust of the secondary combustion chamber swirl vanes to draw efficiently the gas chimney is formed.

これにより、薪を燃やすときは、投入口から薪を本体の燃焼室に投入し、載置部に載置する。 Thus, when burning wood, wood was placed in the combustion chamber of the body from the inlet, it is placed on the placing portion. この状態で薪に点火すると、薪が燃焼していき、これによって生じる未燃焼ガスが載置部の上方へ上昇していくが、水平空気供給管の空気孔が薪投入口の反対側に設けられているので、従来のストーブと違い薪は奥の方から燃えてゆき、二次燃焼室の真下の温度が最高になるように作用する。 When ignited firewood in this state, firewood continue to burn, whereby it rises above the unburned gas mounting part occurs, the air holes of the horizontal air supply pipe is provided on the opposite side of the wood inlet because are, firewood Unlike traditional stove Yuki burning from the direction of the back, acting as the temperature beneath the secondary combustion chamber becomes maximum.

燃焼室で生じた未燃焼ガスは連通板を通して二次燃焼室に抜けようとするが、連通板の開口面積は全面開口しているのではないので大半は燃焼室側に押し戻されて燃焼させられ高温ガスとなる一方、連結板を通過した未燃焼ガスは連結板に対称形に配置された上方と下方に交互に折り曲げられた開口部により渦巻き状に上昇する。 Although unburned gas generated in the combustion chamber would attempt to escape to the secondary combustion chamber through the communication plate, mostly it is burned is pushed back to the combustion chamber side because the opening area of ​​the communication board is not're fully opened while the hot gases, unburned gas that has passed through the coupling plate rises in a spiral shape by opening bent alternately upwardly and downwardly disposed symmetrically to the connecting plate.

連結板を通過した未燃焼ガスは、そのまま煙突に通過するのではなく、連結板の開口面積より小さい開口面積を持つ対流抑止板によって滞留状態になり、下部の燃焼室の熱によりさらに高温状態になる。 Unburned gas that has passed through the connecting plate is not directly pass to the chimney becomes staying state by convection suppressing plate having a smaller opening area than the opening area of ​​the connecting plate, the more high temperature by the heat of the lower portion of the combustion chamber Become.

連結板と対流抑止板の中間の側面に対称に配置された空気供給管からは外気が供給され、充分な空気が渦巻き状にくまなく供給されるので高温の未燃焼ガスが高効率で二次燃焼させられ、煙突からの未燃焼ガスの排気が低減させられる。 From the air supply tubes arranged symmetrically in the middle of the side surface of the connecting plate and the convection suppressing plate outside air is supplied, so sufficient air is supplied throughout the spiral secondary hot unburned gases with high efficiency is burned, exhaust unburned gas from the stack is reduced.

対流抑止板を通過した排気は、二次燃焼室の上部空間である排気室の内壁に備えられたブレード状フィン、渦流形成翼により煙突効果を強化し、連結板と対流抑止板によって抑えられた煙突からの空気の引きを補償する効果を持つ。 Exhaust gas that has passed through the convection suppressing plate, blade-like fins provided on the inner wall of the exhaust chamber is a space above the secondary combustion chamber, to strengthen the chimney effect by swirl vanes, it was suppressed by the connecting plate and the convection suppressing plate It has the effect of compensating the pulling of air from the chimney.

以下、添付図面に基づいて、この発明の実施の形態に係る薪ストーブについて詳細に説明する。 Hereinafter, with reference to the accompanying drawings, wood stove according to an embodiment of the present invention will be described in detail.
図1から図7には、この発明の第一の実施の形態に係る薪ストーブを示している。 In FIGS. 1 to 7 show a wood stove according to the first embodiment of the present invention.

この薪ストーブは、薪が入れられる燃焼室11、19を構成する本体10を備えている。 The wood stove is provided with a body 10 constituting the combustion chamber 11, 19 firewood is placed. 本体10は、直方形ないし円筒形で、中空になっている。 Body 10 is a rectangular shape or cylindrical, and is hollow. また、底部に足12を備えている。 Also it includes a foot 12 at the bottom. また、本体10の上面後側には、燃焼室11に連通する二次燃焼筒20とさらにそれに連結する煙突24が備えられている。 On the upper surface rear of the main body 10, a chimney 24 is provided further connected thereto a secondary combustion tube 20 which communicates with the combustion chamber 11. さらに、燃焼室11内の下側には薪が載置される平面状の載置部が設けられている。 Further, the planar mounting unit firewood is placed is provided on the lower side of the combustion chamber 11. さらにまた、燃焼室11の載置部の中央には筒状の水平空気供給管17が設けられている。 Furthermore, the center of the mounting portion of the combustion chamber 11 is a cylindrical horizontal air supply pipe 17 is provided. この水平空気供給管17は、載置部の後側部分で両側面に複数個の空気孔18を持つ。 The horizontal air supply pipe 17 has a plurality of air holes 18 on both sides in the rear portion of the mounting portion.

また、本体10には薪が投入される投入口15が設けられている。 Also, inlet 15 which firewood is turned is provided on the main body 10. 投入口15は開閉可能な扉13を備えている。 Inlet 15 is provided with an openable door 13. 扉13の端部は投入口の開口部にヒンジ結合されている。 End of the door 13 is hinged to the opening of the inlet. 扉13の中央は、空気量調整弁14が備えられている。 Middle door 13, the air amount adjusting valve 14 is provided.

本体10の上面後側に搭載される二次燃焼筒20は円筒状であり、その頭頂部はドーム状であり、その頭部に煙突24が接続される。 Secondary combustion tube 20 which is mounted on the upper surface rear body 10 is cylindrical, the top portion is dome-shaped chimney 24 is connected to the head.

本体燃焼室11と二次燃焼筒20の接続部分近傍には水平に円盤状の連通板21が設けられる。 Body combustion chamber 11 and the secondary combustion cylinder communication plate 21 disk-shaped horizontally the connecting portion near the 20 are provided. 連通板21の構造は、図4のように、同心円状の二列の複数個の切り欠き部29を持ち、また中央部分には連通筒30を備える。 Structure of communication plate 21, as shown in FIG. 4 has a plurality of notches 29 of the concentric two rows, also in the central portion comprises a communicating tube 30. 切り欠き部29は、図5のように切片が斜め上方に折り曲げられたものと斜め下方に折り曲げられたもので対をなしており、燃焼室11、19からの未燃焼ガスが垂直に二次燃焼室26に連通するのを抑えて渦巻き状の気流をつくる。 Notches 29, two sections are paired with those bent obliquely downward that bent obliquely upward, vertically unburned gases from the combustion chamber 11, 19 as shown in FIG. 5 primary creating a spiral air flow is suppressed from being communicated with the combustion chamber 26. 複数個(図4では3個)の切り欠き部は同心円上に対称に配置されるのが望ましい。 Notch in the plurality (in FIG. 4, three) is desirably are arranged symmetrically on a concentric circle. また、最外周の列と2列目の切り欠き部の位置は、最外周の列の閉鎖部に2列目の切り欠き部に向き合うように配置することが望ましい。 The position of the outermost row and second column of the notch portion is preferably arranged so as to face the cutout portion of the second column to the closure of the outermost rows. 連通筒30の側面も水平方向に切り欠き部29を持ち、連通板の中心部に設けられた開口部から流入する未燃焼ガスを燃焼室26に渦巻き状に取り込む。 Side of the communication tube 30 also has a cutout portion 29 in the horizontal direction, taking spirally combustion chamber 26 unburned gas flowing from the opening provided in the center portion of the communication plate.

また、二次燃焼筒20の中間部には水平方向に円盤状の対流抑止板25が設けられる。 Also, disk-shaped convection suppressing plate 25 is provided horizontally in the middle part of the secondary combustion tube 20. 対流抑止板25の構造はほぼ連通板21と等しいが、切り欠き部の開口面積が連通板21のそれより小さくなるように小さめになっている。 Although equal convection suppressing plate 25 of the structure substantially communication plate 21, the opening area of ​​the notch is in small to be less than that of the communication plate 21. このように構成することによって燃焼室11からの未燃焼ガスは渦巻き状に二次燃焼室26に取り込まれ、閉じ込められて滞留状態になる。 Unburned gases from the combustion chamber 11 by the above configuration is incorporated in a spiral shape in the secondary combustion chamber 26, it becomes trapped by staying state. 対流抑止板25の中心部分は燃焼が確実に行われる部分なので煙突への引きを促進するため単純な開口を複数個設けてもよい。 The central portion of the convection suppressing plate 25 may be provided a plurality of simple openings to facilitate the pulling of the so part combustion is ensured chimney.

連通板21と対流抑止板25で挟まれた空間は二次燃焼室26を形成するが、この二次燃焼室26の中間部分の外壁に外気を取り込む複数個(図2では2個)の空気量調整管22を水平に対称に配置して設ける。 It was sandwiched by communication plate 21 and the convection suppressing plate 25 space forms a secondary combustion chamber 26, air plurality taking outside air into the outer wall of the intermediate portion of the secondary combustion chamber 26 (two in FIG. 2) providing a quantity adjusting tube 22 arranged horizontally symmetrically. 空気量調整管22の外気の流入口には、それぞれ空気量調節弁23が設けられており、外気の流入を好適に調節できるようになっている。 The outside air inlet of the air amount adjusting pipe 22, has been respectively provided with air flow control valve 23, which is to be suitably adjusted external air inflow.

二次燃焼室26で燃焼した未燃焼ガスの排気は、対流抑止板25の開口部を抜けて煙突24に接続される排気室28に入る。 Exhaust unburned gas burned in the secondary combustion chamber 26, enters the exhaust chamber 28 connected to the chimney 24 exits the opening of the convection suppressing plate 25. 排気室28の内壁にはブレード状のフィン、渦流形成翼27が傾斜して取り付けられており、排気を渦巻き状に吸い上げて煙突24の引きを促進する。 Blade-like fins on the inner wall of the exhaust chamber 28, and the swirl vanes 27 are attached inclined, sucked up the exhaust spirally promote pulling chimney 24.

この発明の薪ストーブを用いるときの空気の流れに着目して図7により説明する。 Focusing on the flow of air when using wood-burning stove of the invention will be described with reference to FIG. 投入口15から載置部へ薪を載置し点火する。 Placing and igniting the wood from inlet 15 to mounting portion. 薪は、空気量調整弁14で供給される外気で燃焼を始める。 Firewood, start combustion in outside air supplied by the air control valve 14. この場合、空気は主に燃焼室11,19の上面に沿って流れるが、水平空気供給管17の空気孔18からは、載置部の先の部分に向けて、水平に外気が供給されるので、薪の先端部で一次燃焼が促進され、二次燃焼筒20直下の温度が最も高くなる。 In this case, the air flows mainly along the upper surface of the combustion chamber 11, 19, but from the air hole 18 of the horizontal air supply pipe 17, toward the previous part of the mounting portion, the outside air is supplied horizontally because, the primary combustion in the wood of the distal end portion is accelerated, the temperature just below the secondary combustion tube 20 is the highest. 従来ストーブのように投入口15付近で燃えず、奥のほうから燃えるのでより高温で燃焼し未燃焼ガスの発生が低減される。 Without burning inlet 15 near as conventional stoves, generation of unburned gas burns at a higher temperature because burning from towards the back is reduced.

燃焼しきらなかった未燃焼ガスを含むガスは、載置部の上方にある二次燃焼筒20に上がろうとするが、連通板21に閉鎖部があるため押し戻されて再燃焼するので燃焼の高効率化が図られる。 Gas containing unburned gas not be fully burned, the mounting is when you throw its hat to a secondary combustion tube 20 above the portion, the combustion since the reburning pushed back because of the closure in the communication plate 21 high efficiency is achieved. 一方、連通板21と連通板の中央部の連通筒30を通過した未燃焼ガスは、連通板21と連通筒の開口部である切り欠き部29が特殊な形状をしているので渦巻き状に二次燃焼室26に導かれる。 On the other hand, unburned gas that has passed through the communicating tube 30 of the central portion of the communication plate 21 and the communication plate is spirally since notches 29, which is an opening of the communication plate 21 and the communication tube is a special shape It is led to the secondary combustion chamber 26. 二次燃焼室26は上部に対流抑止板25で蓋がされているので、この空間に一時的な滞留状態が作りだされ、燃焼室11の熱で過熱される。 Since the secondary combustion chamber 26 is a lid at the convection suppressing plate 25 to the upper, temporary staying state in this space is created, it is superheated by the heat of the combustion chamber 11. このような未燃焼ガスに空気調整管22から適量の外気が送り込まれ、渦流となってまんべんなく供給されるので未燃焼ガスが高効率で燃焼させられ、煙突24からの未燃焼ガスの排気が低減させられる。 Such an air adjusting tube 22 in the unburned gas proper amount of outside air is fed, since it is supplied evenly with a vortex is burned unburnt gases at high efficiency, reduce exhaust unburned gases from the stack 24 provoking.

また、この場合、二次燃焼室26から対流抑止板25の開口部である切り欠き部29を通過した排気ガスは、排気室28の内壁に設けられたブレード状のフィン、渦流形成翼27によって渦流となって煙突24に吸い上げようとする煙突効果を高め、逆流を防ぐことができる。 In this case, the exhaust gas passing through the cutout portion 29 is an opening of the convection suppressing plate 25 from the secondary combustion chamber 26, blade-like fins provided on the inner wall of the exhaust chamber 28, the swirl vanes 27 enhances the chimney effect to be Suiageyo chimney 24 becomes vortex, it is possible to prevent backflow.

以上説明したように、この発明の薪ストーブによれば、薪の投入口の扉に設けられた空気量調整弁を通して取り込んだ外気を、薪載置部の先端部に空気孔を持つ水平空気供給管によって薪の先端部分から燃焼させ、その上側に設けた二次燃焼室に未燃焼ガスを導き、二次燃焼室の側面から水平に外気を供給して未燃焼ガスを高効率で燃焼させることができ、煙突からの未燃焼ガスの排気、黒煙を低減することができ、環境を汚染しにくくすることができる。 As described above, according to the stove of the present invention, the outside air taken through the air control valve provided in the door of firewood inlet, horizontal air supply with an air hole at the tip portion of the Takigino portion it burned from the tip portion of the wood by a tube, guide the unburned gas in the secondary combustion chamber provided on its upper side, to burn the unburned gas is supplied outside air horizontally from the side surface of the secondary combustion chamber at a high efficiency can be, exhaust unburned gases from the stack, it is possible to reduce the black smoke can be hard to pollute the environment.

また、二次燃焼筒には連通板の閉鎖部があるので、未燃焼ガスが燃焼室側に押し戻されて燃焼させられるようになり、この点でも未燃焼ガスを高効率で燃焼させることができ、煙突からの未燃焼ガスの排気を低減することができる。 Further, since the secondary combustion tube is closed portion of the communication plate, now unburned gas is combusted is pushed back to the combustion chamber side, also can burn unburned gas at a high efficiency in this respect , it is possible to reduce the exhaust of unburned gases from the stack. さらに、水平空気供給管の空気孔が載置部の先端部に配置されているので、薪は先端部分から燃焼しストーブの奥の方、すなわち二次燃焼筒の直下の温度が高められるので燃焼効率が高められる。 Furthermore, since the air holes of the horizontal air supply pipe is disposed at the front end portion of the mounting portion, firewood the inner part of the stove to burn from the tip portion, i.e., the temperature just below the secondary combustion tube is enhanced combustion efficiency is enhanced.

さらに、従来のように触媒を使用しなくても二次燃焼筒に二次燃焼室を設けるだけの簡単な構造で、充分な空気の供給によって未燃焼ガスを高効率で燃焼させることができ、それだけ、製造コストを低減することができる Further, without using the conventional catalysts as a simple structure of merely providing a secondary combustion chamber to the secondary combustion cylinder, it is possible to burn the unburned gas with high efficiency by the supply of sufficient air, it just makes it possible to reduce the manufacturing cost
