Description

本発明は、木質ペレットを燃焼するとともに、その燃焼火炎を目視可能にガラス窓を形成した木質ペレットストーブの窓付き燃焼室に関するものである。   The present invention relates to a combustion chamber with a window of a wood pellet stove in which wood pellets are burned and a glass window is formed so that the combustion flame can be visually observed.

木質ペレットストーブは、木片を破砕圧縮により成形した非化石燃料である木質ペレットを燃料とし、利用性に乏しい間伐材、製材端材等をバイオマス資源として有効利用するものである。その内部構成は、燃料の木質ペレットを貯留するタンクと木質ペレットを燃焼する燃焼室とに分けられる。燃焼室は、タンクから木質ペレットを供給するペレット供給部と、受けたペレットを燃焼させる燃焼ポットによる燃焼部と、その熱により室内空気を加熱する熱交換部と、この熱交換部まで燃焼気を案内する断熱周壁等から構成され、下部には灰を受ける灰受部等を備える。   A wood pellet stove uses wood pellets, which are non-fossil fuels formed by crushing and compressing wood pieces, as fuel, and effectively uses thinned lumber, sawn timber and the like as biomass resources. The internal structure is divided into a tank for storing wood pellets of fuel and a combustion chamber for burning wood pellets. The combustion chamber includes a pellet supply unit that supplies wood pellets from a tank, a combustion unit using a combustion pot that burns the received pellets, a heat exchange unit that heats indoor air using the heat, and combustion air to the heat exchange unit. It is composed of a heat insulating peripheral wall that guides, and is provided with an ash receiving part for receiving ash at the lower part.

上記燃焼室の断熱周壁には、正面側に開口を形成して内部透視可能なガラス窓を形成することにより、木質ペレットの燃焼火炎を目視可能として木質ペレットストーブ独特の落ち着いた雰囲気を確保することができる。   On the heat insulating peripheral wall of the combustion chamber, an opening is formed on the front side and a glass window that can be seen through is formed, so that the combustion flame of the wood pellet can be seen and a unique atmosphere unique to the wood pellet stove is secured. Can do.

しかし、従来の木質ペレットストーブの燃焼室は、木質ペレットの燃焼に伴う煤がガラスの内面に付着するので、利用者は煩わしい清掃を逃れられず、その手間を省いた場合には、ガラス窓の上部側から次第に煤が付着し、煤汚れによる外観性低下のみならず、燃焼火炎の目視が困難となるので、木質ペレットストーブの特性が半減する事態を甘受せざるを得なかった。   However, in the combustion chamber of a conventional wood pellet stove, soot accompanying the combustion of wood pellets adheres to the inner surface of the glass, so that the user cannot escape troublesome cleaning, and if the labor is saved, the glass window Soot gradually adhered from the upper side, and not only the appearance deteriorated due to the soot stain but also the visual observation of the combustion flame became difficult, so the situation that the characteristics of the wood pellet stove halved had to be accepted.

解決しようとする問題点は、ガラス窓の煤汚れを小さく抑えることができる木質ペレットストーブの窓付き燃焼室を提供することにある。   The problem to be solved is to provide a combustion chamber with a window of a wood pellet stove that can suppress the fouling of glass windows to a small extent.

請求項１に係る発明は、木質ペレットを燃焼する燃焼ポットと、その燃焼気を受けて室内空気に熱を伝達する熱交換部と、この熱交換部まで上記燃焼ポットの燃焼気を案内する断熱周壁とからなり、この断熱周壁に機体正面から内部透視可能なガラス窓を形成した木質ペレットストーブの窓付き燃焼室において、上記ガラス窓の上辺部には、熱交換部までの間でガラス面から内方に後退した位置に下垂板を下垂形成したことを特徴とする。   The invention according to claim 1 is a combustion pot that burns wood pellets, a heat exchange part that receives the combustion air and transfers heat to indoor air, and heat insulation that guides the combustion air in the combustion pot to the heat exchange part. In the combustion chamber with a window of a wood pellet stove, which is formed of a peripheral wall and has a glass window that can be seen through from the front of the machine body on the heat insulating peripheral wall. A drooping plate is formed at a position retracted inward.

請求項２に係る発明は、請求項１の構成において、前記ガラス窓の下辺部には、その外方から給気を受けるための窓下通気部を開口形成したことを特徴とする。   The invention according to claim 2 is characterized in that, in the configuration of claim 1, an opening is formed in the lower side portion of the glass window for receiving air supply from the outside.

請求項３に係る発明は、請求項１の構成において、前記ガラス窓は、断熱周壁に形成した開口部の下辺部の少なくとも一部を残して外方に立ち上がる窓枠部と、この窓枠部と密接するガラス嵌め殺し構成の蓋部材とからなることを特徴とする。   According to a third aspect of the present invention, in the configuration of the first aspect, the glass window includes a window frame portion that rises outward leaving at least a part of a lower side portion of the opening formed in the heat insulating peripheral wall, and the window frame portion. And a lid member having a glass-fitting structure that is in close contact with the glass.

請求項１に係る発明は、燃焼室の下垂板がガラス面から内方に後退した位置で下垂することから、ガラス面に沿う上昇流は下垂板の下端を通って熱交換部に向かい、一方、熱交換部からガラス面に向かう燃焼気は下垂板に沿って下降し、次いで上記上昇流と合流するようにしてガラス面に触れることなく熱交換部に向かう。したがって、熱交換部の燃焼気はガラス面に触れることなく熱交換部に到ることから、ガラス窓上部の煤汚れを小さく抑えることができる。   In the invention according to claim 1, since the bottom plate of the combustion chamber hangs down at a position retracted inward from the glass surface, the upward flow along the glass surface goes to the heat exchange section through the lower end of the bottom plate, The combustion gas from the heat exchanging portion toward the glass surface descends along the hanging plate, and then flows into the heat exchanging portion without touching the glass surface so as to merge with the upward flow. Therefore, the combustion air in the heat exchange part reaches the heat exchange part without touching the glass surface, so that soot contamination on the upper part of the glass window can be kept small.

請求項２に係る発明は、所定の窓下通気部を開口形成したことにより、ストーブ外周の空気が窓下通気部から進入し、ガラス窓の内面に沿って上昇する。したがって、燃焼気はガラス面に触れることなく熱交換部まで上昇した後に排出されてガラス窓下部の煤汚れを防止することができる。   According to the second aspect of the present invention, when the predetermined under-window ventilation portion is formed as an opening, air on the outer periphery of the stove enters from the under-window ventilation portion and rises along the inner surface of the glass window. Therefore, the combustion gas is discharged after rising up to the heat exchanging part without touching the glass surface, and soot contamination at the lower part of the glass window can be prevented.

請求項３に係る発明は、一部を欠いた窓枠部にガラス嵌め殺し構成の蓋部材を密接して構成したことから、ストーブ外周の空気は開口部の下辺部から断熱周壁内に進入し、ガラス窓の内面に沿って上昇する。したがって、燃焼気はガラス面に触れることなく上昇して熱交換部に到ることから、ガラス窓下部の煤汚れを防止することができる。また、断熱周壁の開口部は、ガラス嵌め殺し構成の蓋部材を窓枠部から分離することによってメンテナンス口として機能する。   In the invention according to claim 3, since the cover member having a glass-fitting structure is in close contact with the window frame portion lacking a part, air on the outer periphery of the stove enters the heat insulating peripheral wall from the lower side of the opening. Rise along the inner surface of the glass window. Therefore, the combustion gas rises without touching the glass surface and reaches the heat exchange part, so that soot contamination at the lower part of the glass window can be prevented. Moreover, the opening part of a heat insulation surrounding wall functions as a maintenance opening | mouth by isolate | separating the cover member of a glass fitting structure from a window frame part.

本発明の実施の形態について、以下に図面に基づいて詳細に説明する。
図１は、木質ペレットストーブの内部構成を示す全体透視側面図である。木質ペレットストーブ１は、燃焼部２を中心にその後部に木質ペレットＰの貯留部３と供給部４、下部に灰受部５を備えて木質ペレットＰを燃焼する本体部を構成し、その背面側から戸外に延びる二重管による吸排部６を接続して構成される。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an overall perspective side view showing an internal configuration of a wood pellet stove. The wood pellet stove 1 comprises a main body for burning the wood pellets P with a storage part 3 and a supply part 4 for the wood pellets P at the rear part and a ash receiving part 5 at the lower part with the combustion part 2 as the center. It is configured by connecting a suction / exhaust portion 6 with a double pipe extending from the side to the outside.

燃焼部２は、正面図およびそのＡ―Ａ線断面図を図２、図３にそれぞれ示すように、灰受部５の上部を囲むように断熱周壁１１を巡らせて燃焼室を形成し、その正面に開閉可能な蓋部材１２を有する開口１３を長方形等に形成する。燃焼室内部には、灰受部５に面する底部中央に木質ペレットを燃焼する燃焼ポット１４、その上方に供給部４から木質ペレットを案内するシュータ４ｇ、頂部に熱交換部１５を配置する。燃焼部２の背面側には、熱交換部１５から燃焼気を吸引して強制給排する吸引排気用送風機１６、室内空気を熱交換部１５に送って強制循環する循環送風機１７、燃焼ポット１４の灰掻具１８を前後駆動する駆動部１８ｄ等を配置する。   As shown in FIGS. 2 and 3, respectively, the combustion unit 2 forms a combustion chamber around the heat insulating peripheral wall 11 so as to surround the upper portion of the ash receiving unit 5, as shown in FIGS. An opening 13 having a lid member 12 that can be opened and closed on the front is formed in a rectangular shape or the like. Inside the combustion chamber, a combustion pot 14 for burning wood pellets at the center of the bottom facing the ash receiving part 5, a shooter 4 g for guiding the wood pellets from the supply part 4 above, and a heat exchange part 15 at the top. On the back side of the combustion unit 2, a suction exhaust fan 16 that sucks combustion air from the heat exchange unit 15 and forcibly supplies and discharges, a circulation fan 17 that sends indoor air to the heat exchange unit 15 and forcibly circulates, and a combustion pot 14. A drive unit 18d for driving the ash scraper 18 back and forth is disposed.

燃焼室正面部を詳細に説明すると、蓋部材１２は、開口１３の形状と対応するように耐熱ガラス１２ｗを嵌め殺し固定して内部透視可能なガラス窓を構成し、燃焼部２の前面に開閉可能に軸支する。開口１３の周縁には、その下辺部１３ｂを除き、外方に立ち上がる窓枠部１３ｆを形成する。この窓枠部１３ｆと対応して、蓋部材１２の内面に耐熱パッキン１２ｓを取付ける。この耐熱パッキン１２ｓは、開口１３の上辺１３ｔと両側辺１３ｓ、１３ｓの３辺が蓋部材１２と密接可能に構成して空気流通をシールし、下辺１３ｂは窓下通気部１２ｇとして開放する。また、開口１３の上辺１３ｔの内側部には、下垂板１３ｐを設ける。この下垂板１３ｐは、閉鎖位置にある蓋部材１２から熱交換部１５側に後退した位置で内部透視に支障のない範囲に下垂して配置する   The front part of the combustion chamber will be described in detail. The lid member 12 forms a glass window that can be seen through by fitting and fixing the heat-resistant glass 12w so as to correspond to the shape of the opening 13, and opens and closes the front of the combustion part 2 Support it as possible. A window frame portion 13f that rises outward is formed on the periphery of the opening 13 except for the lower side portion 13b. Corresponding to the window frame portion 13f, the heat-resistant packing 12s is attached to the inner surface of the lid member 12. The heat-resistant packing 12 s is configured such that the upper side 13 t of the opening 13 and the side sides 13 s and 13 s can be in close contact with the lid member 12 to seal the air flow, and the lower side 13 b is opened as a lower window ventilation portion 12 g. A hanging plate 13p is provided on the inner side of the upper side 13t of the opening 13. The drooping plate 13p is arranged to hang down in a range that does not hinder internal fluoroscopy at a position retracted from the lid member 12 in the closed position to the heat exchanging portion 15 side.

上記構成の燃焼室正面部は、下垂板１３ｐが耐熱ガラス１２ｗから熱交換部１５側に離間した位置で下垂することから、耐熱ガラス１２ｗの内面に沿う上昇流は下垂板１３ｐの下端を通って熱交換部１５に向かう。一方、熱交換部１５からガラス面に向かう燃焼気Ｑは下垂板１３ｐに当たって下降し、次いで上記上昇流と合流してガラス面に触れることなく熱交換部１５に向かう。したがって、熱交換部１５の燃焼気はガラス面に触れることなく熱交換の後に排出されてガラス窓上部の煤汚れを防止することができる。   The front part of the combustion chamber having the above configuration hangs down at a position where the hanging plate 13p is spaced from the heat-resistant glass 12w toward the heat exchanging unit 15 side, so that the upward flow along the inner surface of the heat-resistant glass 12w passes through the lower end of the hanging plate 13p. Head to the heat exchange section 15. On the other hand, the combustion air Q from the heat exchanging section 15 toward the glass surface falls on the hanging plate 13p, and then merges with the upward flow toward the heat exchanging section 15 without touching the glass surface. Therefore, the combustion air of the heat exchange part 15 is discharged | emitted after heat exchange, without touching a glass surface, and the soot stain | pollution | contamination of a glass window upper part can be prevented.

その一方で、開口１３の周縁に形成した窓枠部１３ｆは、下辺部１３ｂの少なくとも一部が後退欠損して窓下通気部１２ｇとして開放されることから、この開口１３の下辺部１３ｂからストーブ外周の空気が進入し、ガラス窓の内面に沿う上昇流Ｒが形成される。したがって、蓋部材１２の方向に向かう燃焼気Ｓは、窓下通気部１２ｇからの上昇流Ｒに阻まれてガラス面に触れることなく熱交換部１５まで上昇した後に排出されるので、ガラス窓下部の煤汚れを防止することができる。また、燃焼室の開口１３は、ガラス嵌め殺し型の蓋部材１２を開いて窓枠部１３ｆを開放することによってメンテナンス口として機能する。   On the other hand, since the window frame portion 13f formed at the periphery of the opening 13 is opened as a window lower ventilation portion 12g because at least a part of the lower side portion 13b is retracted and lost, the stove is removed from the lower side portion 13b of the opening 13. Outer air enters, and an upward flow R along the inner surface of the glass window is formed. Accordingly, the combustion air S toward the lid member 12 is discharged after being lifted up to the heat exchanging portion 15 without being touched by the upward flow R from the lower window ventilation portion 12g and touching the glass surface. It is possible to prevent the wrinkles from becoming dirty. The opening 13 of the combustion chamber functions as a maintenance port by opening the glass-fitting type lid member 12 and opening the window frame portion 13f.

次に、燃焼装置について詳細に説明すると、燃焼ポット１４は、図４の平面図（ａ）、正面断面図（ｂ）、側面断面図（ｃ）に示すように、円筒状の周壁２２によって丸型に形成する。周壁２２には、その側方から給気を受けるための多数の側部通気孔２２ｈ…を略全周に形成する。燃焼ポット１４の下端開口内には、木質ペレットを受ける火格子２１を備え、周壁２２の外周には、取付け用のフランジ１４ｆを固定する。燃焼ポット１４の上端開口内には、干渉部材２３を横断架設する。   Next, the combustion device will be described in detail. The combustion pot 14 is rounded by a cylindrical peripheral wall 22 as shown in a plan view (a), a front sectional view (b), and a side sectional view (c) in FIG. Form into a mold. The peripheral wall 22 is formed with a large number of side ventilation holes 22h for receiving air supply from the side thereof on substantially the entire circumference. A fire grate 21 for receiving wood pellets is provided in the lower end opening of the combustion pot 14, and a mounting flange 14 f is fixed to the outer periphery of the peripheral wall 22. In the upper end opening of the combustion pot 14, an interference member 23 is installed in a transverse manner.

側部通気孔２２ｈ…は、旋回流を起こすために、フランジ１４ｆの高さより下位において火格子２１より上位の一定の高さ位置に、各中心軸線が円筒半径線に対して一方側に共通の角度で傾斜し、例えば、左方４５°に傾斜して周壁２２に貫通形成する。干渉部材２３は、木質ペレットが円形の燃焼ポット１４内に拡散堆積するように、木質ペレットの投入経路中でその一部と干渉する位置に配置し、火格子２１の上方に隙間を確保し、かつ、側部通気孔２２ｈ…による旋回流を妨げないように、切欠や貫通孔等の通風部２３ｃを形成して通風性よく形成する。   The side vent holes 22h... Have a common central axis on one side with respect to the cylindrical radial line at a certain height position below the height of the flange 14f and above the grate 21 in order to cause a swirling flow. It inclines at an angle, for example, inclines to the left 45 ° and penetrates the peripheral wall 22. The interference member 23 is arranged at a position where it interferes with a part of the wood pellet charging path so that the wood pellet diffuses and accumulates in the circular combustion pot 14, and a gap is secured above the grate 21, In addition, a ventilation portion 23c such as a notch or a through hole is formed with good ventilation so as not to disturb the swirling flow by the side ventilation holes 22h.

上記構成の燃焼ポット１４は、フランジ１４ｆを介して燃焼室の底部位置に取付けることにより、下方の灰受部５から強制給気を受けつつ、堆積収容した木質ペレットＰを燃焼することができる。この場合において、木質ペレットＰは、燃焼ポット１４に投入の際にその一部が干渉部材２３に干渉することにより、円形の燃焼ポット１４内に偏在堆積することなく、一様に拡散されて均一に効率よく燃焼することが可能となる。   The combustion pot 14 having the above configuration can be attached to the bottom position of the combustion chamber via the flange 14f to burn the wood pellets P stored and received while receiving forced air supply from the lower ash receiving portion 5. In this case, when the wood pellet P is put into the combustion pot 14, a part thereof interferes with the interference member 23, so that the wood pellet P is uniformly diffused without being unevenly deposited in the circular combustion pot 14. It is possible to burn efficiently.

また、燃焼ポット１４の側部通気孔２２ｈ…の軸線がポット中心を外れた一方側に傾斜することから、燃焼の過程で側部通気孔２２ｈ…から燃焼ポット１４の内側に空気が進入した際に、円形の燃焼ポット１４内で、通風性のよい干渉部材２３に妨げられることなく、複数の側部通気孔２２ｈ…が相互間の衝突なしに統合されて旋回力を生じ、その旋回力をうけて燃焼気が上昇する。したがって、旋回による強力な混合作用によって燃焼が促進されるとともに旋回火炎が得られるので、木質ペレットストーブについて、小型の燃焼ポットにより燃焼効率を向上し、かつ、力強い旋回火炎により木質ペレットストーブとしての外観性を向上することができる。   Also, since the axis of the side vent holes 22h of the combustion pot 14 is inclined to one side off the center of the pot, air enters the combustion pot 14 from the side vent holes 22h during the combustion process. Further, in the circular combustion pot 14, the plurality of side air holes 22 h are integrated without colliding with each other without being obstructed by the air-permeable interfering member 23, thereby generating a turning force. The combustion air rises. Therefore, combustion is promoted by swirling powerful mixing action and swirling flame is obtained. For wood pellet stove, combustion efficiency is improved by a small combustion pot, and appearance as wood pellet stove by strong swirling flame. Can be improved.

次に、温風送出装置について詳細に説明すると、熱交換部１５は、図３のＢ―Ｂ線断面図を示す図５のように、循環送風機１７から受けた室内空気を前上がりに傾斜して案内する流路３１を燃焼室頂部中央寄りに形成し、その下面を燃焼気の流路３２とを画成する波板による伝熱板３３として構成する。この伝熱板３３の波板は山谷を多条に並列して形成され、室内空気流路３１の横断面が波型状となる方向に配置し、その吐出部３１ｅを機体前面に開口する。伝熱板３３の左右両側部には、伝熱板３３を横断するように移動した燃焼気Ｂを吸引排気用送風機１６の方向に案内する左右の燃焼気排出路３２ｇ、３２ｇを形成する。   Next, the hot air delivery device will be described in detail. The heat exchanging unit 15 inclines the indoor air received from the circulating blower 17 upward as shown in FIG. 5 showing a cross-sectional view taken along the line BB of FIG. The flow path 31 to be guided is formed near the center of the top of the combustion chamber, and the lower surface thereof is configured as a heat transfer plate 33 by a corrugated plate that defines the flow path 32 for the combustion gas. The corrugated plate of the heat transfer plate 33 is formed in parallel with many valleys and valleys, and is arranged in a direction in which the cross section of the indoor air flow path 31 is corrugated, and the discharge part 31e is opened to the front of the machine body. On the left and right sides of the heat transfer plate 33, left and right combustion air discharge passages 32g and 32g for guiding the combustion air B that has moved across the heat transfer plate 33 in the direction of the suction / exhaust fan 16 are formed.

循環送風機１７は、熱交換部１５の室内空気流路３１の幅寸法と略等しい軸長の横流型送風機により構成し、略同一の幅寸法で燃焼室の背面部を立ち上がる背面部流路１７ｇを介して熱交換部１５と連通する。これら循環送風機１７、背面部流路１７ｇおよび熱交換部１５は、室内空気を循環加熱する温風送出装置を構成する。   The circulation blower 17 is constituted by a cross-flow type blower having an axial length substantially equal to the width dimension of the indoor air flow path 31 of the heat exchanging section 15, and has a back face flow path 17 g rising from the back face of the combustion chamber with substantially the same width dimension. And communicates with the heat exchange unit 15. The circulation blower 17, the back surface flow path 17g, and the heat exchange unit 15 constitute a hot air delivery device that circulates and heats indoor air.

上記構成の温風送出装置は、循環送風機１７から受けた室内空気を熱交換部１５に送り、吐出部３１ｅから温風を室内に送出する。この場合において、熱交換部１５の波型の伝熱板３３により、所要の流路断面積および伝熱面積を確保しつつ、流路抵抗を小さく抑えることができるので、循環送風機１７は横流ファン等による低速の送風機により所要の暖房能力と対応する流量を確保することができる。   The warm air sending device having the above configuration sends the indoor air received from the circulation blower 17 to the heat exchanging unit 15 and sends the warm air into the room from the discharge unit 31e. In this case, the corrugated heat transfer plate 33 of the heat exchanging unit 15 can keep the required flow path cross-sectional area and the heat transfer area while keeping the flow path resistance small. It is possible to secure a flow rate corresponding to a required heating capacity by a low-speed blower such as the one described above.

したがって、上記構成の木質ペレットストーブの温風送出装置は、暖房能力を損なうことなく、送風騒音を低減して木質ペレットの燃焼による落ち着いた雰囲気を確保することができる。また循環送風機１７から熱交換部１５に到る送風流路の断面形状を略一定に構成することによって送風ロスが最小限度に抑えられるので、送風動力を抑えた横流型送風機により木質ペレットストーブの小型化が可能となる。   Therefore, the warm air sending device of the wood pellet stove configured as described above can reduce the blowing noise and ensure a calm atmosphere due to the combustion of the wood pellets without impairing the heating capacity. Moreover, since the air loss is minimized by configuring the cross-sectional shape of the air flow path from the circulation fan 17 to the heat exchanging portion 15 to be substantially constant, the small size of the wood pellet stove is achieved by the cross-flow type fan that suppresses the air blowing power. Can be realized.
