Description

この発明は、薪などを燃料として炉体内で燃焼させる煙突を装備した薪ストーブに関する。 The present invention relates to a wood stove equipped with a chimney that burns firewood or the like in the furnace as fuel.

従来、薪を燃焼させる薪ストーブとしては、例えば、下記の特許文献１（特許公開２０００−４６３３４）が知られている。この薪ストーブＳは、図８に示すように、薪が入れられる燃焼室２を構成する本体１と、この本体１に設けられ薪が投入される投入口３と、本体に設けられ燃焼室２に連通する煙突４とを備えている。このような、薪ストーブＳにおいては、排気ガスに未燃焼ガスを多量に含むことを防止するために、燃焼室２の上側であって煙突４の手前に連通口５を介して連通する二次燃焼室６を設け、この二次燃焼室６内に未燃焼ガスの燃焼を促進する白金触媒７を備えている。これにより、燃焼室２へ、薪を投入し、火をつけて燃焼させると、燃焼室２に燃焼によって発生した未燃焼ガスを含んだ排気ガスは、暖まっているので、連通口５を通り二次燃焼室６へ至り、白金触媒７によって未燃焼ガスの燃焼が促進させられる。このため、排気ガスに含まれる未燃焼ガスが低減されている。 Conventionally, as a soot stove which burns soot, the following patent documents 1 (patent publication 2000-46334) are known, for example. As shown in FIG. 8, the soot stove S includes a main body 1 that constitutes a combustion chamber 2 in which soot is placed, an inlet 3 that is provided in the main body 1 and into which soot is placed, and a combustion chamber 2 that is provided in the main body. And a chimney 4 communicating with the. In such a wood stove S, in order to prevent a large amount of unburned gas from being included in the exhaust gas, a secondary connected to the upper side of the combustion chamber 2 and before the chimney 4 via the communication port 5 is used. A combustion chamber 6 is provided, and a platinum catalyst 7 for promoting combustion of unburned gas is provided in the secondary combustion chamber 6. As a result, when soot is introduced into the combustion chamber 2 and ignited and combusted, the exhaust gas containing unburned gas generated by combustion in the combustion chamber 2 is warmed. Coming to the next combustion chamber 6, combustion of unburned gas is promoted by the platinum catalyst 7. For this reason, the unburned gas contained in exhaust gas is reduced.

また白金触媒を使わない薪ストーブとしては、下記の特許文献２（特許公開２００４−７７０６０）が知られている。
この薪ストーブは、図９に示すように、本体１０の燃焼室１１内に薪が載置される平面状の載置部１３を設け、本体１０に、載置部１３の上側中央に向けて斜め上方から外気を供給可能な流出口４１を有した傾斜空気供給管４０を、流出口４１が載置部１３の中心線に対して対称に配置されるように複数設け、更に、載置部１３の上側中央に向けて、水平に外気を供給可能な流出口５１を有した水平空気供給管５０を、流出口５１が載置部１３の中心線に対して対称に配置されるように複数設けた。 Moreover, the following patent document 2 (patent publication 2004-77060) is known as a wood stove which does not use a platinum catalyst.
As shown in FIG. 9, the soot stove is provided with a planar placement portion 13 on which the soot is placed in the combustion chamber 11 of the main body 10, and the main body 10 is directed toward the upper center of the placement portion 13. A plurality of inclined air supply pipes 40 having outlets 41 capable of supplying outside air from obliquely above are provided so that the outlets 41 are arranged symmetrically with respect to the center line of the mounting part 13, and further, the mounting part A plurality of horizontal air supply pipes 50 having outlets 51 capable of supplying outside air horizontally are arranged so that the outlets 51 are arranged symmetrically with respect to the center line of the mounting portion 13 toward the upper center of the unit 13. Provided.

これにより、触媒を使用しなくても簡単な構造で、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、未燃焼ガスの発生を低減し、製造コストの軽減を図るとしている。
特許公開２０００−４６３３４公報特許公開２００４−７７０６０公報 As a result, an uncombusted gas is burned with high efficiency by supplying sufficient air with a simple structure without using a catalyst, thereby reducing the generation of unburned gas and reducing the manufacturing cost.
Patent Publication 2000-46334 Patent Publication No. 2004-77060

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。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。
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。 However, in such a conventional wood stove, the unburned gas is secondary-combusted to clean the exhaust gas. However, the structure is complicated because the secondary combustion chamber is provided in the upper part and the catalyst is provided in this. In addition, there is a problem that the parts cost is high and the manufacturing cost is high. In addition, in the method using the inclined air supply pipe, the condition for air suction is critical.
The present invention has been made in view of the above-described problems. By using an unburned gas in a secondary combustion chamber and keeping it at a high temperature without using a catalyst, sufficient air is supplied from the outside to the secondary combustion chamber. The purpose is to provide a wood-burning stove that can be used even in urban areas by efficiently burning unburned gas, obtaining a high-efficiency heating effect, and at the same time reducing exhaust black smoke.

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よ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。 In order to achieve such an object, a soot stove of the present invention comprises a main body constituting a combustion chamber into which soot is placed, a soot inlet provided in the main body and into which soot is introduced, and a combustion chamber provided in the main body. A soot stove comprising a secondary combustion cylinder communicating with the chimney and a chimney communicating with the secondary combustion cylinder is provided with a placement part on which soot is placed in the combustion chamber, A horizontal air supply pipe for taking in air flowing in from the air amount adjusting valve is provided, the horizontal air supply pipe has a plurality of air holes on both side surfaces in the opposite direction to the soot inlet, and further, Is provided with a secondary combustion cylinder on the upper side of the opposite combustion chamber, the secondary combustion cylinder has a plurality of air quantity adjustment pipes that can be supplied by adjusting the amount of outside air from the lateral direction, and mounting of the air quantity adjustment pipes The connecting plate is attached to the secondary combustion cylinder below The upper secondary combustion cylinder is provided with a convection suppression plate, a secondary combustion chamber is formed between the two plates, and the exhaust chamber wall above the convection suppression plate is disposed on the exhaust chamber. A vortex forming blade that efficiently draws gas into the chimney is constructed.

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。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。 Thereby, when burning soot, soot is thrown into the combustion chamber of a main body from an insertion port, and it mounts in a mounting part. When the soot is ignited in this state, the soot is combusted and the unburned gas generated thereby rises above the mounting part, but the air hole of the horizontal air supply pipe is provided on the opposite side of the soot inlet. Therefore, unlike conventional stoves, soot burns from the back and acts to maximize the temperature directly below the secondary combustion chamber.

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。 The unburned gas generated in the combustion chamber tries to escape to the secondary combustion chamber through the communication plate, but since the opening area of the communication plate is not fully open, most of it is pushed back to the combustion chamber and burned. On the other hand, the unburned gas that has passed through the connecting plate rises spirally through openings that are alternately bent upward and downward, which are arranged symmetrically on 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。 The unburned gas that has passed through the connecting plate does not pass through the chimney as it is, but is retained by the convection suppression plate having an opening area smaller than the opening area of the connecting plate, and is further heated by the heat of the lower 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。 Outside air is supplied from the air supply pipe arranged symmetrically on the intermediate side surface between the connecting plate and the convection suppression plate, and sufficient air is supplied in a spiral shape, so that high-temperature unburned gas is highly efficient and secondary. Combusted and exhaust of unburned gas from the chimney 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 suppression plate has been enhanced by the chimney effect by blade-like fins and vortex formation blades provided on the inner wall of the exhaust chamber, which is the upper space of the secondary combustion chamber, and is suppressed by the connecting plate and convection suppression plate. Compensates for air pull 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。
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。 Hereinafter, based on an accompanying drawing, a wood stove concerning an embodiment of this invention is explained in detail.
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。本体１０は、直方形ないし円筒形で、中空になっている。また、底部に足１２を備えている。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。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。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。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 soot stove includes a main body 10 that constitutes combustion chambers 11 and 19 in which soot is placed. The main body 10 has a rectangular shape or a cylindrical shape and is hollow. Also, the foot 12 is provided at the bottom. Further, a secondary combustion cylinder 20 communicating with the combustion chamber 11 and a chimney 24 connected to the secondary combustion cylinder 20 are provided on the rear side of the upper surface of the main body 10. Further, a planar placement portion on which the soot is placed is provided on the lower side in the combustion chamber 11. Furthermore, a cylindrical horizontal air supply pipe 17 is provided at the center of the mounting portion of the combustion chamber 11. The horizontal air supply pipe 17 has a plurality of air holes 18 on both side surfaces at 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。投入口１５は開閉可能な扉１３を備えている。扉１３の端部は投入口の開口部にヒンジ結合されている。扉１３の中央は、空気量調整弁１４が備えられている。 In addition, the main body 10 is provided with an insertion port 15 into which a bag is inserted. The insertion port 15 includes a door 13 that can be opened and closed. The end of the door 13 is hinged to the opening of the inlet. An air amount adjustment valve 14 is provided in the center of the door 13.

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。 The secondary combustion cylinder 20 mounted on the rear side of the upper surface of the main body 10 has a cylindrical shape, the top of the head has a dome shape, and a 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。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。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。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。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。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。 A disc-shaped communication plate 21 is provided horizontally in the vicinity of the connecting portion between the main body combustion chamber 11 and the secondary combustion cylinder 20. As shown in FIG. 4, the structure of the communication plate 21 has a plurality of concentric notch portions 29 in two rows, and a communication tube 30 in the central portion. As shown in FIG. 5, the notch 29 is paired with a section that is bent obliquely upward and a part that is bent obliquely downward, and the unburned gas from the combustion chambers 11, 19 is secondary to the vertical. A spiral airflow is created by suppressing communication with the combustion chamber 26. It is desirable that a plurality of (three in FIG. 4) notch portions are arranged symmetrically on a concentric circle. Further, it is desirable that the positions of the outermost row and the second row of cutout portions are arranged so as to face the second row of cutout portions at the closed portion of the outermost row. The side surface of the communication cylinder 30 also has a notch 29 in the horizontal direction, and unburned gas flowing from an opening provided at the center of the communication plate is taken into the combustion chamber 26 in a spiral shape.

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。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。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。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。 Further, a disc-shaped convection suppression plate 25 is provided in the horizontal direction at the intermediate portion of the secondary combustion cylinder 20. The structure of the convection suppression plate 25 is substantially the same as that of the communication plate 21, but is small so that the opening area of the notch is smaller than that of the communication plate 21. By comprising in this way, the unburned gas from the combustion chamber 11 is taken in the secondary combustion chamber 26 in the shape of a spiral, becomes confined, and becomes a residence state. Since the central portion of the convection suppression plate 25 is a portion where combustion is reliably performed, a plurality of simple openings may be provided in order to promote pulling to the 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。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 space sandwiched between the communication plate 21 and the convection suppression plate 25 forms a secondary combustion chamber 26. A plurality of (two in FIG. 2) air that takes in outside air into the outer wall of the intermediate portion of the secondary combustion chamber 26. The quantity adjusting pipes 22 are arranged horizontally symmetrically. An air amount adjusting valve 23 is provided at each of the outside air inlets of the air amount adjusting pipe 22 so that the inflow of the outside air can be suitably adjusted.

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。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。 The unburned gas exhausted in the secondary combustion chamber 26 passes through the opening of the convection suppression plate 25 and enters the exhaust chamber 28 connected to the chimney 24. Blade-shaped fins and swirl forming blades 27 are attached to the inner wall of the exhaust chamber 28 at an inclination, and the exhaust is sucked up in a spiral shape to promote the pulling of the 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。投入口１５から載置部へ薪を載置し点火する。薪は、空気量調整弁１４で供給される外気で燃焼を始める。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。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。 The flow of air when using the wood stove of the present invention will be described with reference to FIG. A soot is placed on the placement portion from the insertion port 15 and ignited. The soot starts to burn with the outside air supplied by the air amount adjustment valve 14. In this case, air mainly flows along the upper surfaces of the combustion chambers 11 and 19, but external air is supplied horizontally from the air holes 18 of the horizontal air supply pipe 17 toward the tip of the mounting portion. Therefore, the primary combustion is promoted at the tip portion of the soot, and the temperature immediately below the secondary combustion cylinder 20 becomes the highest. Unlike conventional stoves, it does not burn near the inlet 15, but burns from the back, so it burns at a higher temperature and the generation of unburned gas 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。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。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。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。 The gas containing unburned gas that has not been burned tries to rise to the secondary combustion cylinder 20 above the mounting portion. However, since the communication plate 21 has a closed portion, it is pushed back and recombusted. High efficiency is achieved. On the other hand, the unburned gas that has passed through the communication plate 21 and the communication tube 30 at the center of the communication plate has a spiral shape because the notch 29 that is the opening of the communication plate 21 and the communication tube has a special shape. It is guided to the secondary combustion chamber 26. Since the secondary combustion chamber 26 is covered with a convection restraining plate 25 at the top, a temporary residence state is created in this space and is overheated by the heat of the combustion chamber 11. Since an appropriate amount of outside air is fed into the unburned gas from the air adjustment pipe 22 and is evenly supplied as a vortex, the unburned gas is burned with high efficiency, and exhaust of the unburned gas from the chimney 24 is reduced. Be made.

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。 Further, in this case, the exhaust gas that has passed from the secondary combustion chamber 26 through the notch 29 that is the opening of the convection suppression plate 25 is caused by blade-shaped fins and eddy current forming blades 27 provided on the inner wall of the exhaust chamber 28. The chimney effect of trying to suck up into the chimney 24 as a vortex can be enhanced, and backflow can be prevented.

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 wood stove of the present invention, the outside air taken in through the air amount adjusting valve provided in the door of the wood inlet is used to supply horizontal air having an air hole at the tip of the wood mounting portion. Combusting from the tip of the soot by the pipe, leading the unburned gas to the secondary combustion chamber provided above it, and supplying the outside air horizontally from the side of the secondary combustion chamber to burn the unburned gas with high efficiency Therefore, exhaust of unburned gas from the chimney and black smoke can be reduced, making it difficult 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。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。
In addition, since the secondary combustion cylinder has a closed portion of the communication plate, the unburned gas is pushed back to the combustion chamber side and burned. In this respect, the unburned gas can be burned with high efficiency. The exhaust of unburned gas from the chimney can be reduced. Further, since the air hole of the horizontal air supply pipe is arranged at the tip of the mounting portion, the soot burns from the tip and the temperature at the back of the stove, that is, the temperature immediately below the secondary combustion cylinder, is increased. Efficiency is increased.

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 Furthermore, with a simple structure in which a secondary combustion chamber is provided in the secondary combustion cylinder without using a catalyst as in the past, unburned gas can be burned with high efficiency by supplying sufficient air, Therefore, the manufacturing cost can be reduced.
