Description

この発明は、屋外給排気式の石油燃焼器具やガス燃焼器具に用いる給排気装置に関するものである。   The present invention relates to an air supply / exhaust device used for an outdoor air supply / exhaust type oil combustion appliance or gas combustion appliance.

従来より、この種の給排気装置に於いては、内側の排気筒と外側の給気筒との間の給気路入口部が、突出構造の為に雪や氷が堆積し易く、堆積すると給気路入口部で閉塞されて燃焼部への給気不足となり、異常燃焼となるので、室外側のフランジに発熱体を取り付けて、該フランジ及び仕切板に付着した雪や氷は発熱体に通電し、排気筒内を通り排気トップに先端部を位置させた駆動桿を手動で操作することで、除去するようにしたものであった。   Conventionally, in this type of air supply / exhaust device, the air supply passage inlet between the inner exhaust cylinder and the outer supply cylinder has a protruding structure, and snow and ice are likely to accumulate. Since the air supply is blocked at the inlet of the air passage, the combustion section becomes insufficient and abnormal combustion occurs. Therefore, a heating element is attached to the flange on the outdoor side, and snow and ice attached to the flange and partition plate are energized to the heating element. However, the drive rod with its tip positioned on the exhaust top passing through the exhaust cylinder is manually operated to be removed.

ところでこの従来のものでは、発熱体への通電が必要であり、何時通電を開始するのかが問題であり、外気温が低い時や吹雪等の天候によって通電を開始した場合、通電時間が長くなったり、切り忘れ等も考えられ、電力が無駄に消費されて不経済であったり、又人為的な操作で手間がかかったり、センサを付けて自動的にしても制御が複雑となったり、高価になる等の課題を有するものであった。   By the way, in this conventional thing, it is necessary to energize the heating element, and when energization is started is a problem. When the energization is started when the outside air temperature is low or due to weather such as snowstorm, the energization time becomes longer. Or power is wasted and it is uneconomical. Also, it takes time and effort due to manual operation. It had the problem of becoming.

この発明はこの点に着目し上記課題を解決する為に、燃焼後の排気及び燃焼用の空気の給気を、壁の貫通穴を貫通する給排気筒本体と給排気筒トップを備えた給排気装置を介して屋外より行うようにし、前記給排気筒本体と前記給排気筒トップはそれぞれ前記給排気筒本体の給気筒と排気筒、前記給排気筒トップの給気筒と排気筒を有し、前記給排気筒本体の給気筒と前記給排気筒トップの給気筒、前記給排気筒本体の排気筒と前記給排気筒トップの排気筒がそれぞれ嵌合してなる二重筒構造の給排気装置に於いて、前記給排気筒トップの外方の給気筒と内方の排気筒との間の給気路入口部に対向する排気筒内には、内壁から中央部に向かって突出し且つ排気ガスの流れに沿って配置された複数の伝熱フィンを設けたものである。   In order to solve the above-mentioned problems by focusing on this point, the present invention supplies the exhaust gas after combustion and the air supply for combustion with a supply / exhaust cylinder main body that penetrates through a through-hole in the wall and an intake / exhaust cylinder top. The air supply / exhaust cylinder main body and the air supply / exhaust cylinder top have a supply cylinder and an exhaust cylinder of the supply / exhaust cylinder main body, and a supply cylinder and an exhaust cylinder of the supply / exhaust cylinder top, respectively. , Supply / exhaust of a double cylinder structure in which the supply cylinder of the supply / exhaust cylinder body and the supply cylinder of the supply / exhaust cylinder top, and the exhaust cylinder of the supply / exhaust cylinder body and the exhaust cylinder of the supply / exhaust cylinder top are respectively fitted In the apparatus, an exhaust pipe projecting from an inner wall toward a central portion and exhausted in an exhaust pipe opposed to an inlet passage between an outer supply cylinder and an inner exhaust pipe on the top of the supply / exhaust cylinder. A plurality of heat transfer fins arranged along the gas flow are provided.

以上のようにこの発明によれば、給排気装置内を流れて屋外に排出される高温の排気ガスを利用して、給気路入口部に堆積する雪や氷を溶かすようにしたものであり、即ち、排気筒内の給気路入口部と対向する部分に排気ガスの流れと平行となるように複数の伝熱フィンを設けたことで、排気ガスの熱を伝熱フィンで受熱しこの熱を給気路入口部と対向する排気筒に伝熱して該排気筒が加熱され、この部分に堆積する雪や氷を溶かすものであり、又燃焼停止中に堆積した雪や氷も排気ガスを集中させることで、燃焼開始からの短時間で瞬時に溶かすことが出来、常に良好な給排気が行え異常燃焼の心配がないものであり、しかも本来排気される排気ガスを利用した極めて簡単で安価な構成で実現させたものである。   As described above, according to the present invention, the high-temperature exhaust gas that flows through the air supply / exhaust device and is discharged outdoors is used to melt snow and ice accumulated at the inlet of the air supply passage. That is, by providing a plurality of heat transfer fins in a portion facing the inlet of the air supply passage in the exhaust pipe so as to be parallel to the flow of the exhaust gas, the heat of the exhaust gas is received by the heat transfer fins. Heat is transferred to the exhaust pipe facing the inlet of the air supply passage to heat the exhaust pipe and melt the snow and ice that accumulate in this part. By concentrating the gas, it can be melted instantly in a short time after the start of combustion, it can always supply and exhaust properly, and there is no fear of abnormal combustion, and it is extremely easy to use exhaust gas that is originally exhausted. This is realized with an inexpensive configuration.

次にこの一実施形態の作動について説明する。
先ず燃焼器具を運転開始すれば、屋外からの空気が給気路入口部１８を流通し給排気装置１に於ける給排気筒本体４の内側排気筒７と外側給気筒９の間と給排気筒トップ５の外側排気筒１４と内側給気筒１５の間の空間の給気路８とを通過して屋内の燃焼器具に燃焼用空気が供給され、燃焼器具からの排気ガスが給排気装置１における給排気筒本体４の内側排気筒７から給排気筒トップ５の外側排気筒１４を流通し、給排気筒トップ５の屋外側先端部における排気口１６から屋外へ排気されるものである。 Next, the operation of this embodiment will be described.
First, when the operation of the combustion appliance is started, air from the outside flows through the supply passage inlet 18 and the supply / exhaust between the inner exhaust cylinder 7 and the outer supply cylinder 9 of the supply / exhaust cylinder main body 4 in the supply / exhaust device 1. Combustion air is supplied to the indoor combustion appliance through the air supply path 8 in the space between the outer exhaust cylinder 14 of the cylinder top 5 and the inner supply cylinder 15, and the exhaust gas from the combustion appliance is supplied to the supply / exhaust device 1. The exhaust pipe 14 is circulated from the inner exhaust cylinder 7 of the supply / exhaust cylinder main body 4 to the outer exhaust cylinder 14 of the supply / exhaust cylinder top 5, and is exhausted to the outside from the exhaust port 16 at the outdoor end portion of the supply / exhaust cylinder top 5.

又給排気筒トップ５の外側排気筒１４内の給気路入口部１８付近では、外側排気筒１４内の排気路６を流通して来た排気ガスは、伝熱フィン２１間を流通することで、該伝熱フィン２１がこの排気ガスの熱を受熱し、この熱を外側排気筒１４に伝熱することにより、給気路入口部１８付近に堆積する雪や氷を確実に溶解することが出来るものであり、給気路入口部１８が閉塞されることで給気不足となって異常燃焼することもなく、常に安心して使用出来るものであり、しかも、屋外に排気される排気ガスの熱を極めて簡単な構成で利用するようにしたことで、極めて安価に実現したものである。   Further, in the vicinity of the air supply path inlet 18 in the outer exhaust cylinder 14 of the outer exhaust cylinder top 5, the exhaust gas that has circulated through the exhaust path 6 in the outer exhaust cylinder 14 circulates between the heat transfer fins 21. Thus, the heat transfer fins 21 receive the heat of the exhaust gas, and transfer the heat to the outer exhaust cylinder 14, so that the snow and ice accumulated in the vicinity of the air supply path inlet 18 can be surely melted. The air supply passage inlet 18 is closed so that the air supply becomes insufficient and abnormal combustion does not occur, and it can always be used with peace of mind. By using heat with a very simple configuration, it is realized at a very low cost.
