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、排気ガスを給気路入口部側に案内する排気ガイドを備え、この排気ガイドは、前記給排気筒トップの排気筒の内壁近くで平行に備えられ中央を排気ガスが流通可能な水平筒部と、該水平筒部の後端から徐々に傾斜して排気ガスを前記水平筒部まで誘導し中央を排気ガスが流通可能な誘導部とで構成されると共に、前記水平筒部の開口端面と前記給気路入口部の開口端面とが略同一面上に位置するように前記排気筒内に配設され、前記給排気筒トップの排気筒内の前記給気路入口部付近では、前記給排気筒トップの排気筒内を流通して来た前記排気ガスの一部は、前記排気ガイドの前記誘導部外周から前記水平筒部外周に案内されて、前記給気路入口部と対向する前記給排気筒トップの排気筒の内壁に沿って流通し、残りの排気ガスは前記排気ガイドを構成する前記誘導部内および前記水平筒部内を流通するようにしたものである。 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, exhaust gas is introduced into the supply passage inlet side in the exhaust tube facing the supply passage inlet portion between the outer supply cylinder and the inner exhaust tube on the top of the supply / exhaust tube. with a guide to exhaust guide, the exhaust guide is parallel with the inner wall near the supply chimney top chimney A horizontal cylinder part that is capable of circulating exhaust gas in the center, and a guide part that is gradually inclined from the rear end of the horizontal cylinder part to guide the exhaust gas to the horizontal cylinder part and in which the exhaust gas can flow in the center. The exhaust tube at the top of the supply / exhaust tube is configured and disposed in the exhaust tube so that the opening end surface of the horizontal tube portion and the opening end surface of the air supply passage inlet portion are located on substantially the same plane. A portion of the exhaust gas that has circulated in the exhaust pipe at the top of the air supply / exhaust cylinder is guided from the outer periphery of the guide section to the outer periphery of the horizontal cylinder section. Then, it flows along the inner wall of the exhaust pipe at the top of the air supply / exhaust cylinder facing the inlet of the air supply passage, and the remaining exhaust gas flows through the guide section and the horizontal cylinder section constituting the exhaust guide. It is what I did .

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１７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 air supply passage inlet 17, and between the inner exhaust cylinder 7 and the outer supply cylinder 9 of the air supply / exhaust cylinder body 4 in the air 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１７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の一部は、排気ガイド２０の誘導部２２に案内されて、給気路入口部１７と対向する外側排気筒１４の内壁に沿って流通するように水平筒部２１で抑制され、このように排気ガスが外側排気筒１４の内壁に沿って流通することで該内壁が加熱され、給気路入口部１７に雪や氷が付着している場合は、確実に雪や氷を溶解することが出来るものであり、給気路入口部１７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。   In addition, in the vicinity of the air supply path inlet 17 in the outer exhaust cylinder 14 of the upper and lower exhaust cylinder top 5, a part of the exhaust gas flowing through the exhaust path 6 in the outer exhaust cylinder 14 is part of the guide part of the exhaust guide 20. 22, and is suppressed by the horizontal cylinder portion 21 so as to circulate along the inner wall of the outer exhaust cylinder 14 facing the air supply passage inlet section 17, and thus the exhaust gas extends along the inner wall of the outer exhaust cylinder 14. When the inner wall is heated and the snow and ice are attached to the air supply passage inlet 17, the snow and ice can be dissolved reliably. It is possible to always use it without anxiety due to shortage of air supply due to being blocked, and to use the heat of exhaust gas exhausted outdoors with a very simple configuration. Therefore, it is realized at a very low cost.

更に排気ガイド２０の中央を残りの排気ガスが流通して排気口１６に向かうものであり、又外側排気筒１４内の給気路入口部１７付近を通過した排気ガスもスムーズに排気口１６に向かうので、排気ガイド２０が排気の邪魔になることもないものである。   Further, the remaining exhaust gas flows through the center of the exhaust guide 20 toward the exhaust port 16, and the exhaust gas that has passed in the vicinity of the supply passage inlet 17 in the outer exhaust cylinder 14 smoothly enters the exhaust port 16. The exhaust guide 20 does not get in the way of exhaust.
