【考案の詳細な説明】
この考案は芯を急速に降下する時、空気流入部
から芯挿通孔間隙に空気を供給したり、可燃ガス
室のガスに引火して爆風を発生させたり、不燃ガ
ス室に石油ガスと拡散させたりして、自動消火せ
しめる石油燃焼器が、転倒時消火不能となつたり
再着火を起したりしないようにする考案である。[Detailed explanation of the device] This device supplies air from the air inlet to the core insertion hole gap when the core is rapidly descending, ignites the gas in the combustible gas chamber to generate a blast, and This is a device that prevents petroleum combustors, which automatically extinguish the fire by spreading petroleum gas into the room, from becoming unable to extinguish the fire or from re-igniting when it falls over.
従来このような目的として芯外筒の外方に貯油

しながら一般に連通孔は転倒方向の規制のないも
のでは全周スリツト、また前後左右の転倒方向の

する必要があり、また貯油室は連通孔と芯降下し
たあとの芯挿通間隙を介して外気とも連してお
り、転倒時の自動消火性能が非常に悪くなるもの
であつた。 Conventionally, for this purpose, an oil storage chamber was configured on the outside of the core outer cylinder, and the oil contained in the core that leaked outward through the core insertion gap of the core outer cylinder when it fell was collected from the communication hole into the oil storage chamber. A leading configuration is known. With this configuration, oil does not flow out into the combustion section which maintains a high temperature, so there is no fear of re-ignition. However, in general, the communication hole needs to be made up of slits all around the circumference for machines that do not have restrictions on the direction of falling, and slits in about 4 locations for machines that have restrictions on the direction of fall, front, back, left, and right, and the oil storage chamber must be made up of the communication hole and the center drop. It was also connected to the outside air through the gap between the cores and the automatic extinguishing performance in the event of a fall was extremely poor.
この考案は上記の欠点を改善するもので、芯外

5が作動するものであつてもよい。 This invention improves the above-mentioned drawbacks by providing an oil storage chamber 2 on the outside of the core outer cylinder 1, and guiding the oil that flows down the core outer cylinder 1 when it falls down from the communication hole 3 to the oil storage chamber 2. In an oil combustor that automatically extinguishes fire by rapidly lowering the wick 4, the communication hole 3 is provided with a gravity-operated opening/closing plate 5, which closes the communication hole 3 located above when the oil combustor falls. This relates to fire extinguishing equipment. In the figure, 6 is an air hole through which air flows into the lead insertion gap when the lead is lowered, 7 is a return spring that acts on the lead up/down mechanism 8 to quickly lower the lead 4, and 9 is a lead up/down knob. The shape of the opening/closing plate 5 can be arbitrarily selected, and there is no regulation on the direction of falling, and the slit-like communication hole 3 is open all around.
In the case of a type having a core outer cylinder 1, the ring may be constructed with a ring having a larger diameter than the core outer cylinder 1, and the ring may move to the communication hole 3 when falling and close the communication hole 3 located above when falling. Further, in the case where the direction of falling is restricted, the opening/closing plate 5 corresponding to the communication hole 3 located above may be operated as shown in FIG.
以上の如き構成であるから転倒の開始をおもり
などで検出すれば芯4は自動的に降下し、例えば
空気孔6から空気を吸引して火勢を弱め数秒で消
火が完了する。 With the above configuration, if the start of the fall is detected using a weight or the like, the wick 4 will automatically descend, and, for example, air will be sucked in from the air hole 6 to weaken the flame and complete the extinguishment in a few seconds.
ところで芯4から気化した油は空気より重い気
体となるから、芯4に含まれた油と共に最下部の
連通孔3から貯油室2に流入する。また燃焼熱で
あたためられた燃焼ガスや消火間近の炎は芯挿通
間隙を上方へ移動動し、やがて燃焼ガスは上方と
なつて芯挿通間隙から外部へ流出する。このよう
な燃焼ガスの流れは対流を起して芯挿通間隙の下
部において燃焼部に触れて高温度で酸素を含んだ
空気を流入することとなり、該空気は連通孔3か
ら貯油室2内に入り貯油室2内にも対流を起す。
この結果消火装置作動直後に貯油室2内に流入し
た気化ガスは拡散して高温度の空気と共に上方に
位置する連通孔3から芯挿通間隙へ供給し、転倒
後数秒で消火するはずの炎の勢いを強め、更に対
流も強まる結果消火不能になるものであつた。 By the way, since the oil vaporized from the wick 4 becomes a gas heavier than air, it flows into the oil storage chamber 2 through the lowermost communicating hole 3 together with the oil contained in the wick 4. Furthermore, the combustion gas heated by the combustion heat and the flame that is about to be extinguished move upward through the wick insertion gap, and eventually the combustion gas flows upward through the wick insertion gap to the outside. This flow of combustion gas causes convection, touches the combustion part at the lower part of the core insertion gap, and causes high-temperature, oxygen-containing air to flow in, and the air flows into the oil storage chamber 2 through the communication hole 3. Convection also occurs within the oil storage chamber 2.
As a result, the vaporized gas that flowed into the oil storage chamber 2 immediately after the fire extinguishing system was activated diffuses and is supplied together with high-temperature air to the wick insertion gap from the communication hole 3 located above, causing the flame to be extinguished within a few seconds after the fire extinguisher falls. The force of the fire increased, and as a result of the stronger convection, it became impossible to extinguish the fire.
この考案では転倒時上方に位置する連通孔3を
開閉板5によつて閉じたから、高温度の空気が芯
挿通間隙から貯油室2内に流入して対流を起して
も、上方に位置する連通孔3から芯挿通間隙へ可
燃ガスが供給されることはなく貯油室2上方に貯
えられるだけとなつた。この為芯挿通間隙に残つ
た炎は多量の空気と可燃ガスの供給を受けること
ができず、数秒で自然消火するようになつた。 In this design, since the communication hole 3 located above is closed by the opening/closing plate 5 in the event of a fall, even if high temperature air flows into the oil storage chamber 2 from the core insertion gap and causes convection, the communication hole 3 located above is closed. The combustible gas is not supplied from the communication hole 3 to the core insertion gap and is only stored above the oil storage chamber 2. For this reason, the flame remaining in the wick insertion gap could not receive a large amount of air and combustible gas, and began to extinguish itself in a few seconds.
以上のようにこの考案では転倒時芯下げ消火直
後の燃焼部へ油が流出し再着火を起すトラブル防
止の為の貯油室と連通孔との構成が、逆に芯下げ
消火性能の劣化をもたらしていたのを、簡単な重
力による開閉板構造を追加することによつて克服
したもので、開閉板開閉の為に特別な操作を不用
とし、自然に行なわれるから取扱性能が複雑とな
らず、製造上のコストアツプもごくわずかですむ
ようになつた。 As described above, in this design, the structure of the oil storage chamber and the communication hole is designed to prevent oil from flowing into the combustion section immediately after the wick is lowered and extinguished, causing re-ignition in the event of a fall, but this conversely leads to a deterioration of the wick extinguishing performance. This was overcome by adding a simple gravity-operated opening/closing plate structure, which eliminates the need for special operations to open and close the opening/closing plate, and since it is done naturally, handling performance is not complicated. The increase in manufacturing costs has also become negligible.
