Abstract

PURPOSE:To eliminate offensive smell upon extinguishing fire and permit to extinguish the fire instantaneously by a method wherein a wick section shutter, blockading the tip section of the wick and a combustion chamber after descending the wick upon extinguishing the fire, and a discharging path shutter, blockading a combustion exhaust gas discharging path also upon extinguishing the fire, are provided in the instrument. CONSTITUTION:The wick 1 is descended by a wick ascending and descending mechanism and the tip section thereof is pulled into a guide fitment 3 for sliding of the wick. Subsequently, the wick section shutter 4 and the discharging path shutter 14 are operated into blockading conditions thereof to extinguish perfectly the fire instantaneously. According to this operation, the supply of fuel for the combustion chamber is intercepted perfectly and the fire is extinguished perfectly immediately after finishing fire extinguishing operation, therefore, it is very safe in case of emergency.

Description

【発明の詳細な説明】 産業上の利用分野 本発明は暖房、調理等に利用される液体燃料燃焼器にか
かるものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a liquid fuel combustor used for heating, cooking, etc.

暖房、へ等に用いられる液体燃料燃焼器としては、石油
ストーブ、石油コンロ等が広く実用に用いられている。Oil stoves, oil stoves, and the like are widely used as liquid fuel burners for heating, heating, etc.

しかし、これらの液体燃料燃焼器は消火した時に強い臭
気を発生する欠点があシ、勇足すべき快適性を備えたも
のとは言い難い。However, these liquid fuel combustors have the disadvantage of emitting a strong odor when extinguished, and cannot be said to be extremely comfortable.

また、いまひとつの欠点は芯を下げて消火操作を行なっ
ても燃焼室下端部に小火炎による残り火が暫時存続し、
その後に始めて完全消火に至る欠点があり、安全上満足
し得るものでばなかった。Another drawback is that even if you lower the wick and extinguish the fire, embers caused by small flames will remain at the bottom of the combustion chamber for a while.
There was a drawback that the fire was completely extinguished only after that, and it was not satisfactory in terms of safety.

点を生じる結果となシ、消火時臭気と瞬間消火の両方を
同時に実現し得るものはなかった。On the one hand, the residual flame after wicking has the effect of reducing odor by burning the odor-causing substances during ignition. Therefore, by instantaneously extinguishing the wick after wicking, On the other hand, this resulted in the disadvantage of increasing the odor during extinguishing, and there was no one that could simultaneously achieve both the odor during extinguishing and instant extinguishing.

である。As shown in FIG. 1, during combustion, the phantom wick shutter 4 and the discharge passage shutter 14 are opened, and the wick 1 is raised by a wick up-and-down mechanism (not shown) so that the tip end is in the combustion chamber.
It protrudes from the lower end of the. Subsequently, the tip of the moon core 1 is ignited by an igniter (not shown), and the air chambers 6, 7 are ignited.
．． 8, combustion air enters the combustion chamber 5 through the small holes in the front plate 9 and rear plate 1o of the combustion chamber as shown by the arrows, thereby starting combustion. Furthermore, the combustion exhaust gas flows from the exhaust passage 13 into the combustion chamber outer cylinder 1.
1 is discharged outside. The glass window 12 is provided to transmit and supply the radiant heat generated by the red heat of the combustion front plate 9 to the outside.

First, the lamp wick 1 is lowered by a wick up/down mechanism (not shown), and the tip end is drawn into the wick sliding guide fitting 3. Then, the wick shutter 4 and the discharge passage shutter 14 are operated to close the lamp, and the lamp is completely extinguished instantly.

て安全である。Effects of the Invention As described above, the cause of the residual flame after extinguishing, which is a drawback of the conventional example, is that the fuel supply to the combustion chamber does not completely stop at the same time as the breath is lowered, and the fuel supply drops by -g, albeit by a small amount. be. However, in the present invention, after the lamp wick is lowered, the space communicating between the tip of the lamp wick and the combustion chamber is closed with a shutter, and the combustion exhaust gas exhaust path is also closed with the shutter, so that the fuel supply to the combustion chamber is completely prevented. The system is shut off and completely extinguished instantly after the extinguishing operation is completed, making it extremely safe even in an emergency.

構成である。In addition, the cause of the odor during extinguishing, which is a conventional drawback, is that the extremely small amount of fuel supplied to the combustion chamber after extinguishing the fire is not combusted, but odorous substances such as aldehydes (VC) deteriorate under the city temperature of the combustion chamber and are supplied to the outside. It depends. However, in the present invention, the supply of odor-causing substances to the location with odor-causing conditions is completely stopped by the effects of the above-mentioned two shutters, so that the shortcomings of one of the conventional methods are improved. This is a practical solution that makes it possible to completely eliminate both defects at the same time, as it was difficult to eliminate both defects at the same time because the disadvantages of the other would worsen if The value is extremely large.0In addition, even just one of the lamp wick shutter and the exhaust passage shutter has a considerable effect, but by having both shutters, an extremely small amount of fuel can be supplied to the combustion chamber through a small gap. -1- This is an effective configuration that completely eliminates even the slightest odor generated by the process.

The structure can be omitted, and the above-mentioned effect of fully opening at the time of extinguishing a fire can be implemented without any loss.
