本考案は密閉型温風暖房機に関し、特に、熱交換器の構
造の改良に関する。[Detailed Description of the Invention] The present invention relates to a closed hot air heater, and particularly to an improvement in the structure of a heat exchanger.
上記密閉型温風暖房機は、室内空気をを熱交換器の燃焼
ガス通路外壁に接触させて熱交換即ち加熱することによ
り暖房を行うようになっている。The closed hot air heater described above performs heating by bringing indoor air into contact with the outer wall of a combustion gas passage of a heat exchanger to exchange heat, that is, heat the room air.
このような暖房機においては、第１図に示す如く熱交換
用送風機８により熱交換器４に向けて熱交換用の空気が
吹出されるわけであるが、ファンケーシング８Ａのファ
ン８Ｂに遠い部分から吹出される空気の方がファン８Ｂ
に近い部分から吹出される空気より流速が速く、又風量
も多い。In such a heater, air for heat exchange is blown toward the heat exchanger 4 by the blower 8 for heat exchange, as shown in FIG. The air blown out from the fan 8B
The flow velocity is faster and the air volume is larger than that of the air blown from the area closer to the air.
このため、従来のように、熱交換器がパイプを多数個配

て室内に吹出される温風温度が不均一になり快適な暖房
空間を得ることが出来ない欠点があった。For this reason, conventional heat exchangers have a structure in which a large number of pipes are arranged or steel plates are assembled in a lattice pattern, and the heat exchange performance is uniform in all parts. The temperature of the air heated after passing through the fan casing 8A is higher at part A in the figure and lower at part B, corresponding to the hot air blowing position of the fan casing 8A. This has the disadvantage that the temperature of the hot air blown into the room becomes uneven, making it impossible to obtain a comfortable heated space.
そこで、本考案は以上のような従来の実情に鑑み、熱交

である。Therefore, in view of the above-mentioned conventional circumstances, the present invention has a structure in which a heat exchanger is provided with radiation fins on the outer wall of the combustion gas flow passage pipe, and the flow rate and volume of the heat exchange air blown onto the outer wall of the pipe are adjusted. A closed hot air heater that aims to equalize the temperature of the air blown into the room by setting the size and position of the radiation fins and the shape of the main body according to the situation, as well as setting the position of the heat receiving fins installed on the inner wall of the pipe. It provides:
以下、本考案の一実施例を第１図及び第２図に基づいて

れている。In Fig. 1, 1 is the main body casing, 2 is a combustion air blower disposed inside the main body casing 1, 3 is a combustion chamber, 4 is a heat exchanger, 4A is a combustion gas outlet, and 5 is a fuel supply. Six fuel cocks and seven fuel governors are interposed in the passage.
８は熱交換用送風機、８Ａはそのケーシング、８Ｂはフ
ァンである。8 is a heat exchange blower, 8A is its casing, and 8B is a fan.
９は熱交換用送風機８からの送風が燃焼用送風機２等の
制御部に洩れないようにするための空気ガイドである。Reference numeral 9 denotes an air guide for preventing the air blown from the heat exchange blower 8 from leaking to the control section of the combustion blower 2 and the like.
かかる構成において、燃焼用空気送風機２を始動すると
、燃焼用空気は燃焼室３に導入される。In such a configuration, when the combustion air blower 2 is started, combustion air is introduced into the combustion chamber 3.
燃料は燃料コツクロ及び燃料ガバナ７を経て燃焼室３に
供給され、燃焼用空気との混合気となって燃焼する。The fuel is supplied to the combustion chamber 3 via a fuel tank and a fuel governor 7, and is combusted as a mixture with combustion air.
燃焼ガスは熱交換器４で放熱し、排出口４Ａを介して屋
外に放出される。The combustion gas radiates heat in the heat exchanger 4 and is discharged outdoors through the exhaust port 4A.
一方、熱交換用送風機８のファン８Ｂを回転駆動すると
熱交換器４に送風がなされる。On the other hand, when the fan 8B of the heat exchange blower 8 is driven to rotate, air is blown to the heat exchanger 4.
送られた風は熱交換器４外壁に接触し、受熱して温風と
なり暖房空間に吹出される。The sent air comes into contact with the outer wall of the heat exchanger 4, receives heat, becomes warm air, and is blown out into the heating space.
以上の密閉温風暖房機において、本考案は熱交換器４を
第２図に示す如く構成する。In the above sealed hot air heater, the heat exchanger 4 of the present invention is configured as shown in FIG.
図において、１０は熱交換器を構成する燃焼ガス流通路
パイプで両端部側が大径に、中央部側が小径に猛威され
ている。In the figure, reference numeral 10 denotes a combustion gas flow passage pipe constituting a heat exchanger, which has a large diameter at both ends and a small diameter at the center.
１２は夫々燃焼ガス流通路パイプ１０の上記両側壁部の
縦方向に複数個列設された放熱フィンである。Reference numeral 12 designates a plurality of heat radiation fins arranged in a row in the vertical direction on both side walls of the combustion gas flow passage pipe 10, respectively.
このフィン１２は第１図にも示すように燃焼ガス流通路
パイプ１０の燃焼ガス入口側においてその列設間隔がま
ばらになるように配設すると共にその長さを短くして放
熱面積が小さくなるようにする一方、燃焼ガスの排出口
４Ａ側においてその列設間隔を密にすると共にその長さ
を長く猛威して放熱面積が大きくなるようにする。As shown in FIG. 1, the fins 12 are arranged so that the spacing between them is sparse on the combustion gas inlet side of the combustion gas flow passage pipe 10, and the length thereof is shortened to reduce the heat dissipation area. On the other hand, on the side of the combustion gas discharge port 4A, the distance between the rows is narrowed and the length thereof is increased to increase the heat dissipation area.
１３は燃焼ガス流通路パイプ１０内壁の燃焼ガス排出口
４Ａ側に設けられたフィンである。Reference numeral 13 denotes a fin provided on the inner wall of the combustion gas flow passage pipe 10 on the side of the combustion gas outlet 4A.
そして、かかる熱交換器４はアルミダイカストで猛威し
、この場合フィン１２．１３を一体形成したパイプ１０
の２分割体を貼り合わせて構成する。The heat exchanger 4 is made of aluminum die-casting, and in this case, a pipe 10 with integrally formed fins 12 and 13 is used.
It is constructed by pasting together the two parts.
以上のような熱交換器４を使用すれば、送風機８のファ
ンケーシング８Ａのファン８Ｂに近い側から吹出される
速度が遅く、その風量の少い燃焼用空気はこれが通過す
る熱交換器４の燃焼ガス入口側に短いフィン１２Ａがま
ばらに配設されている為熱交換器４からの受熱が緩和さ
れ熱交換後室内に吹出される空気温度が従来に比べ低い
ものになる。If the heat exchanger 4 as described above is used, the combustion air blown out from the side of the fan casing 8A of the blower 8 near the fan 8B is slow, and the combustion air with a small amount of air is blown out from the heat exchanger 4 through which it passes. Since the short fins 12A are sparsely arranged on the combustion gas inlet side, the heat received from the heat exchanger 4 is relaxed, and the temperature of the air blown into the room after heat exchange is lower than before.
これに対し、ファンケーシング８Ａのファン８Ｂに遠い
側から吹出される速度が速く、その風量の多い燃焼用空
気はこれが通過するパイプ１０の燃焼ガス排出口４Ａ側
に長いフィン１２Ｂが密に配設され、しかも本実施例で
は燃焼ガス流通路パイプ１０内壁の燃焼ガス排出口４Ａ
側に燃焼ガスからの受熱を向上するフィン１３を備えて
いる為熱交換器４からの受熱が促進され熱交換後室内に
吹出される空気温度が従来に比べ高いものになる。On the other hand, long fins 12B are densely arranged on the combustion gas exhaust port 4A side of the pipe 10 through which the combustion air blown out from the far side by the fan 8B of the fan casing 8A is fast and has a large volume. Moreover, in this embodiment, the combustion gas outlet 4A on the inner wall of the combustion gas flow passage pipe 10
Since the side is provided with fins 13 that improve heat reception from the combustion gas, heat reception from the heat exchanger 4 is promoted, and the temperature of the air blown into the room after heat exchange is higher than that of the conventional case.
更に、パイプ１０中間部を小径に猛威したから該中間部
を熱交換用空気が素通りして受熱が緩和され、従来最も
高い温度で室内に吹出されていた空気温度を低くするこ
とが出来る。Furthermore, since the middle part of the pipe 10 is made small in diameter, the heat exchange air passes through the middle part, reducing heat reception, and the temperature of the air, which conventionally was blown into the room at the highest temperature, can be lowered.
以上のようにして、熱交換用送風機８のファンケーシン
グ８Ａ位置によって吹出される熱交換用空気に流速・風
量のムラがあっても、熱交換後室内に吹出される空気温
度を均一なものにすることが出来る。As described above, even if the heat exchange air blown out by the fan casing 8A position of the heat exchange blower 8 has uneven flow velocity and air volume, the temperature of the air blown into the room after heat exchange can be made uniform. You can.
