≪暖房装置の作用≫
次に、各図を参照して本発明の実施形態に係る暖房装置100の作用を説明する。
≪Action of heating device≫
Next, the operation of the heating device 100 according to the embodiment of the present invention will be described with reference to each figure.

図1に示す操作部11において運転スイッチがオン操作されると、図3に示すバーナ部2は予熱を開始し、燃油供給部6、空気供給部7(図1参照)が駆動させられて、バーナ部2で燃油が燃焼させられる。 When the operation switch is turned on in the operation unit 11 shown in FIG. 1, the burner unit 2 shown in FIG. 3 starts preheating, and the fuel supply unit 6 and the air supply unit 7 (see FIG. 1) are driven. Fuel is burned in the burner section 2.

バーナ部2で発生した炎や燃焼ガスは、外筒3内で完全燃焼しながら上昇し、背面部321に沿って上方向に流れる。外筒3を通った燃焼ガスは、熱交換器4に流入し、熱交換器4を通過した後、排気管43を経て排気ガスとして屋外に排気される。この際、外筒3は、バーナ部2で発生した炎や燃焼ガスによって加熱され、外筒3の前面部311から前方に向けて輻射熱が放出される。 The flame or combustion gas generated in the burner portion 2 rises while being completely burned in the outer cylinder 3, and flows upward along the back surface portion 321. The combustion gas that has passed through the outer cylinder 3 flows into the heat exchanger 4, passes through the heat exchanger 4, and then is exhausted to the outside as exhaust gas through the exhaust pipe 43. At this time, the outer cylinder 3 is heated by the flame or combustion gas generated in the burner portion 2, and radiant heat is released from the front portion 311 of the outer cylinder 3 toward the front.

そして、対流用ファン5の駆動が開始されると、対流用ファン5によって室内の空気が本体ケース1内に取り込まれる。図3に示すように、対流用ファン5によって取り込まれて、前側に送り出された上側の空気(矢印b)は、加熱された外筒3や熱交換器4と熱交換して加熱され、温風となって縦長吹出部13(図1及び図2参照)から室内に吹き出される。 Then, when the driving of the convection fan 5 is started, the air in the room is taken into the main body case 1 by the convection fan 5. As shown in FIG. 3, the upper air (arrow b) taken in by the convection fan 5 and sent out to the front side exchanges heat with the heated outer cylinder 3 and the heat exchanger 4 to be heated and heated. It becomes a wind and is blown into the room from the vertically long blowing portion 13 (see FIGS. 1 and 2).

また、対流用ファン5によって取り込まれて、対流用ファン5の前側に送り出された下側の空気(矢印c)は、後仕切板172の上側垂直部172aに当たって案内されて、上側垂直部172aに沿って下方向(矢印d,k方向)に流れる。さらに空気は、傾斜部172bに当たり、その空気の一部が傾斜部172bに当たった抵抗で傾斜部172bを上ってスリット172d内に入り込んだ後、突出片172eにガイドされて、空間S1をドーム部32の背面部321に沿って上方向(矢印g方向)に流れる。 Further, the lower air (arrow c) taken in by the convection fan 5 and sent out to the front side of the convection fan 5 hits the upper vertical portion 172a of the rear partition plate 172 and is guided to the upper vertical portion 172a. It flows downward (arrows d and k) along the line. Further, the air hits the inclined portion 172b, and a part of the air goes up the inclined portion 172b due to the resistance hitting the inclined portion 172b and enters the slit 172d, and then is guided by the projecting piece 172e to dome the space S1. It flows upward (in the direction of arrow g) along the back surface portion 321 of the portion 32.

これにより、後仕切板172の前側の空間S1が温度上昇するのを抑制することができる。このため、外筒3の背面部321の輻射熱によって、対流用ファン5の手前側にある後仕切板172が加熱されるのを抑制することができる。 As a result, it is possible to suppress the temperature rise of the space S1 on the front side of the rear partition plate 172. Therefore, it is possible to prevent the rear partition plate 172 on the front side of the convection fan 5 from being heated by the radiant heat of the back surface portion 321 of the outer cylinder 3.

また、前記傾斜部172bに当たった空気は、傾斜部172bに案内されて下側(矢印e,k方向)に流れ、下側垂直部172cと、本体ケース1の後側内壁1aとの間の通気路1bを通って、バーナ部2の下方(矢印f方向)に流れた後、下側吹出部(図示省略)から本体ケース1外へ流れる。
また、対流用ファン5からの空気の一部は、図10矢印hで示すように、外筒3の背面部321と後仕切板172との間を通り、外筒3の底部324と接続部材8の下仕切板82との間を通った後、本体ケース1外へ流れる。
このようにして、室内の暖房が行われる。
Further, the air that hits the inclined portion 172b is guided by the inclined portion 172b and flows downward (in the directions of arrows e and k), and is between the lower vertical portion 172c and the rear inner wall 1a of the main body case 1. After flowing downward (in the direction of arrow f) of the burner portion 2 through the ventilation passage 1b, it flows out of the main body case 1 from the lower outlet portion (not shown).
Further, as shown by the arrow h in FIG. 10, a part of the air from the convection fan 5 passes between the back surface portion 321 of the outer cylinder 3 and the rear partition plate 172, and the bottom portion 324 of the outer cylinder 3 and the connecting member. After passing between the partition plate 82 of 8, it flows out of the main body case 1.
In this way, the room is heated.

また、支持板177および点火プラグ22の温度上昇は、前述した支持板177と後仕切板172とが接触していることによる伝熱と、外筒3の背面部321と後仕切板172との間を流れる空気と、傾斜部172bに案内されて下側(矢印e,k方向)に流れる空気によって効果的に温度上昇を抑制することができる。 Further, the temperature rise of the support plate 177 and the spark plug 22 is caused by heat transfer due to the contact between the support plate 177 and the rear partition plate 172 described above, and the heat transfer between the back surface portion 321 of the outer cylinder 3 and the rear partition plate 172. The temperature rise can be effectively suppressed by the air flowing between them and the air guided by the inclined portion 172b and flowing downward (directions of arrows e and k).

以上のように、本発明の実施形態に係る暖房装置100は、燃焼を行うバーナ部2と、バーナ部2の上方に配置された外筒3と、外筒3の側部に設けた冷却用の空気が通る空間S1と、空間S1内であり外筒3の側部に設け、外筒3からの放熱を遮熱する後仕切板172と、空間S1内に空気を送風して外筒3と後仕切板172とを冷却する対流用ファン5と、外筒3の側壁部に設けた第1の穴329と、後仕切板172に設けた第2の穴172hと、第1の穴329と第2の穴172hとを貫通して先端部がバーナ部2に臨み、ロッド221の一部及び碍子部222の一部が空間S1内に配設された点火プラグ22と、を備え、空間S1内に第1の穴329を覆うようにして外筒3に密着させた支持板177を設け、支持板177に点火プラグ22を取り付けるとともに、支持板177は、第2の穴172hを塞ぐようにして後仕切板172に接触させて取り付けるようにした。 As described above, in the heating device 100 according to the embodiment of the present invention, the burner portion 2 for combustion, the outer cylinder 3 arranged above the burner portion 2, and the cooling device provided on the side portion of the outer cylinder 3 are provided.

The spark plug 22 is provided with a tip portion facing the burner portion 2 through the second hole 172h and a spark plug 22 in which a part of the rod 221 and a part of the porcelain portion 222 are arranged in the space S1. A support plate 177 is provided in S1 so as to cover the first hole 329 and is in close contact with the outer cylinder 3, a spark plug 22 is attached to the support plate 177, and the support plate 177 closes the second hole 172h. Then, it was attached in contact with the post-partition plate 172.

かかる構成によれば、暖房装置100は、支持板177と後仕切板172とを接触させたことにより、支持板177と点火プラグ22の熱を効率よく伝熱させることができ、さらに、対流用ファンから送られる空気で冷却を行うことにより、前記バーナの燃焼に全く影響を与えることなく前記点火プラグおよび前記支持板を冷却させることができ、よって、点火プラグ22の温度上昇を抑制して部品耐久性を向上させることができる。 According to such a configuration, the heating device 100 can efficiently transfer the heat of the support plate 177 and the spark plug 22 by bringing the support plate 177 into contact with the rear partition plate 172, and further, for convection. By cooling with the air sent from the fan, the spark plug and the support plate can be cooled without affecting the combustion of the burner at all, thereby suppressing the temperature rise of the spark plug 22 and the component. Durability can be improved.

また、図10に示すように、支持板177は、第1の穴329より大きく、支持板設置孔172h(第2の穴)より小さい閉塞面部177aと、閉塞面部177aの周囲から立ち上がった立上壁部177bと、立上壁部177bから外周へ延びたフランジ部177cと、を備え、フランジ部177cの外筒側の面は、後仕切板172と接触している。 Further, as shown in FIG. 10, the support plate 177 has a closed surface portion 177a larger than the first hole 329 and smaller than the support plate installation hole 172h (second hole), and a rising surface portion 177a rising from the periphery of the closed surface portion 177a. A wall portion 177b and a flange portion 177c extending from the rising wall portion 177b to the outer periphery are provided, and the surface of the flange portion 177c on the outer cylinder side is in contact with the rear partition plate 172.

かかる構成によれば、暖房装置100は、後仕切板172の背面側から後仕切板172の第2の穴172hを貫通させて、支持板177を外筒3に取り付けできる。これにより、支持板177を外筒3へ取り付けると同時に、支持板177を後仕切板172に接触させ、支持板177と後仕切板172との伝熱経路を形成でき、組み立て工数の削減を図ることができる。
また、前記伝熱経路部を別部品とした場合に比べ、部品点数が削減できコストダウンが図れるほか、メンテナンス時の組み立ての際に前記伝熱経路部を取り付け忘れる心配がなく、作業性の向上を図ることができる。
また、立上壁部177bは支持板177と後仕切板172との伝熱経路となるため、対流用ファン5から送られる一部の空気が通過することによって冷却を行うことができ、点火プラグ22および支持板177を冷却させることができる。
According to such a configuration, the heating device 100 can attach the support plate 177 to the outer cylinder 3 by penetrating the second hole 172h of the rear partition plate 172 from the back surface side of the rear partition plate 172. As a result, at the same time as attaching the support plate 177 to the outer cylinder 3, the support plate 177 can be brought into contact with the rear partition plate 172 to form a heat transfer path between the support plate 177 and the rear partition plate 172, and the number of assembly steps can be reduced. be able to.
