【産業上の利用分野】この発明は枠体内の異常加熱を防
止する石油燃焼器の安全構造に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety structure for an oil combustor which prevents abnormal heating in a frame.

構成となっている。2. Description of the Related Art An oil combustor of a vertical core type is designed to allow air to flow into the lower part of a combustion section by allowing air to flow into the side wall of a frame to supply air necessary for combustion. A gap is formed, and combustion air is supplied to the combustion section from this gap.

て急速消火する構造を備えている。Further, an air chamber is provided adjacent to the outside of the wick accommodating cylinder, and an air circulation hole is opened in the air chamber so that the oil gas and the air circulation hole diffused into the air chamber during combustion of the oil combustor. A mixed gas is created by the inflowing air, and when the wick is lowered to a position lower than the vent, the mixed gas that diffuses into the air chamber immediately ignites due to the flame at the tip of the wick and explosively burns, generating It is equipped with a structure that blows out the flame at the tip of the wick by the combustion gas that has been burned to rapidly extinguish the flame.

【発明が解決しようとする課題】上記の急速消火構造は
地震等の非常時に自動消火装置を作動させる緊急消火装
置として有効であるが、燃焼中は燃焼部の熱で枠体の内
部空間や空気室が直接加熱されており、空気室が高温と
なって空気室内の混合ガスの蒸気圧が上昇するので、燃
焼中に空気流通孔が開口していると空気室内の混合ガス
が枠体の内部空間に流出することがある。The rapid fire extinguishing structure described above is effective as an emergency fire extinguisher for operating the automatic fire extinguisher in an emergency such as an earthquake. Since the chamber is directly heated and the temperature of the air chamber rises and the vapor pressure of the mixed gas in the air chamber rises, if the air circulation holes are opened during combustion, the mixed gas in the air chamber will become inside the frame. May flow into space.
【0005】この時、枠体の内部には燃焼部で発生する
上昇気流によって空気孔から燃焼部に向かう空気流が形
成されているので、空気流通孔から流出した混合ガスの
ほとんどは空気流と一緒に燃焼部に取り込まれていた。At this time, since an ascending air current generated in the combustion section forms an air flow from the air holes toward the combustion section inside the frame, most of the mixed gas flowing out from the air flow holes is the air flow. It was taken into the combustion section together.
【0006】そして、石油燃焼器の上方から風が吹き付

熱され、空気室内の混合ガスの蒸気圧が上昇して空気流
通孔から流出する混合ガス量が多くなり、下向きの火炎
によって空気流通孔付近の混合ガスが引火して空気流通
孔7に炎が付着する恐れがあった。When the wind blows from above the oil combustor and the flame in the combustion section is directed downward, the flame may blow out from the gap in the lower part of the combustion section along the wick containing cylinder. The inner space of the frame and the air chamber are further heated by this, the vapor pressure of the mixed gas in the air chamber rises and the amount of the mixed gas flowing out from the air circulation hole increases, and the downward flame causes the mixed gas in the vicinity of the air circulation hole. Might ignite and a flame might adhere to the air circulation hole 7.
【0007】また、誤ってガソリンを使用して燃焼する
と、ガソリンの蒸気が空気流通孔から流出した時には、
引火点の低いガソリンは燃焼部の熱によって枠体の内部
空間で引火して重大な火災事故を引き起こす恐れがあっ
た。When gasoline is erroneously used for combustion, when gasoline vapor flows out from the air flow holes,
Gasoline with a low flash point could ignite in the internal space of the frame due to the heat of the combustion part, causing a serious fire accident.

た時にはカバーによって火炎が直接空気流通孔に届かな
いようになっており、空気流通孔から流出する混合ガス
への引火を防止する構成となっている。As a countermeasure for this, there is a method in which a cylindrical cover is attached around the air circulation hole and the tip of the cover is extended to the vicinity of the side wall of the frame, and the mixed gas flowing out from the air circulation hole is inside the cover. Through the air holes of the frame body to the outside of the frame body. Further, when the air is blown to the combustor, the flame prevents the flame from directly reaching the air circulation hole, so that the mixed gas flowing out from the air circulation hole is prevented from catching fire.

燃焼部の熱で直接加熱される為に空気流通孔から流出す

った時には空気流通孔から流出する混合ガス量が多くな
る。However, in the above structure, since the air chamber and the cover are directly heated by the heat of the combustion portion, the amount of the mixed gas flowing out from the air circulation hole cannot be suppressed, and when the temperature of the air chamber becomes high, the air is blown. The amount of mixed gas flowing out from the flow holes increases.

えることが課題となっている。When the amount of the mixed gas flowing out from the air flow hole becomes large, a part of the mixed gas flowing out from the opening of the cover is taken into the internal space of the frame by the air flow from the air hole 1a toward the combustion section. However, it is not preferable for safety, and it is a problem to suppress the temperature rise of the internal space of the frame and the air chamber.

Since the flame blown out from the gap between and does not reach the lower space A by being blocked by the heat shield plate 13, the lower space A and the air chamber 6 are not further heated, and the mixed gas in the air chamber 6 flows through the air. It is possible to suppress the outflow from the hole 7 to the lower space A,
There is no fear of catching fire near the air circulation hole 7.

By partitioning the inside of the frame 1 into the lower space A and the upper space B by the heat, the heat of the combustion section 12 is blocked by the heat shield plate 13, and the air in the lower space A of the frame 1 becomes the heat of the combustion section 12. Is not directly heated in the lower space A and the air chamber 6
Since the temperature rise is suppressed, the amount of mixed gas flowing out from the air circulation hole 7 can be suppressed.

まれることはなくなった。Since the air flow toward the combustion section 12 and the air flow toward the air chamber 6 are formed independently, the heat shield plate 1
The lower space A partitioned by 3 is not affected by the ascending airflow of the combustion section 12, and the lower space A has the air holes 1a.
Since air flows in and out by communicating with the outside air at
Even if the mixed gas flows out from the above, the mixed gas is diffused into the air outside the lower space A and the frame body 1 and thinned, so that the mixed gas is not taken into the combustion section 12.

Since the heat of the heat shield plate 13 is dissipated into the lower space A and the core housing cylinder 4 and the air chamber 6 are not strongly heated, the lower space A can be burned while being kept at a low temperature. It was
