Abstract

PURPOSE:To reduce nonburnt gas occurring at the time of fire extinguishing drastically and to prevent a foul odor from occurring. CONSTITUTION:At the time of fire extinguishing, wick installation metal fittings 2 are descended also according as a wick 1 descends. Fuel 3 in a cylinder 18 is compressed by an expansion part 17 of the wick installation metal fittings 2 and spouted out to the tip of the wick 1 through a gap 16. Evaporation of fuel resulting from remaining heat is inhibited as the tip of the wick 1 or inner walls of wick inner cylinders 5 and 4 are cooled suddenly by sensible heat of the spouted fuel. Thus, necessary time from fire extinguishing action to complete fire extinction becomes short and stabilized, generation of nonburnt gas after the fire extinction becomes very little, and air pollution and generation of a foul odor can be reduced.

行っている。BACKGROUND OF THE INVENTION Conventionally, wick nozzles used in kerosene stoves and the like generate low noise, are simple in construction, and easy to operate. On the other hand, the odor caused by unburned gas emitted during fire extinguishing was very strong. Particularly in the living room of a typical home, the odor generated when extinguishing a fire is discharged directly into the room, so countermeasures against the odor generated during extinguishing are either by taking the combustor outside to extinguish the fire, or by sufficiently ventilating the room.

を低減させる。However, moving equipment during combustion is extremely dangerous, and indoor ventilation reduces the heating effect because warm air is replaced with outside air.

灯芯バーナの消火時の臭気の発生は、失火後、燃料が気
化し、高温部分で熱分解されたガスによるものである。The odor generated when a wick burner is extinguished is due to the gas that vaporizes after a misfire and is thermally decomposed in the high-temperature part.

生した。The wick burner lowers the wick that was exposed in the combustion chamber when the fire is extinguished between the inner flame tube and the wick guide tube, causing a lift misfire in a lack of oxygen. However, even after the misfire, the fuel continued to vaporize until the temperature of the wick and the inner and outer tubes cooled down, producing unburned gas and odor.

火に至る時間が、バラツキ不安定であった。At the end of the misfire, only a portion of the wick is combusted, and the flame reaches a flame-holding state in which the wick rotates.As the temperature of the wick decreases, the amount of combustion decreases, and the time from extinguishing action to misfire varies. It was unstable.

一実施例を図面を用いて説明する。The present invention cools the tip of the wick by forcibly supplying fuel to the tip of the wick at the same time as the wick is lowered when extinguishing.
The amount of evaporation of fuel after extinguishing is extremely small, the amount of evaporation of fuel is small, the extinguishing time is uniform and short, and the combustion state during extinguishing can be improved. An embodiment of the present invention will be described below with reference to the drawings.

る。The lamp wick 1 is attached to the window mounting bracket 2, and its lower part is submerged in the fuel 3, so that it can move up and down in the gap 6 formed by the inner cylinder 4 and the inner cylinder 5 (the operating mechanism is not shown). It is attached. A space for a primary combustion chamber 9 is formed above the gap 6 by an inner flame tube 7 and an outer flame tube 8, and a secondary combustion chamber 11 is provided above the secondary combustion chamber 9, which is surrounded by 1o during combustion. It is.

いる。Numerous holes 1 are provided at the top of the core guide tube as inflow paths for combustion air.
2. A large number of holes 13 are provided in the inner flame cylinder 7 and the outer flame direction 8, and the outer cylinder 14
A gap 16 is formed between the outer flame tube 8 and the outer flame tube 8. The window mounting bracket 2 is configured to slide on the inner cylinder 4 through a gap 16, and -1... The window mounting bracket 2 has an enlarged portion 17 at its lower part, and the enlarged portion 17 A shilling 18 is attached to the outer periphery of the tank 19 so as to be closed at the bottom of the tank 19.

がおこなわれる。When the ignition heater (not shown) is energized, ignition occurs at the upper end of the lamp wick 1, which is sufficiently soaked with fuel, and combustion begins. The high-temperature gas generated by combustion generates an upward airflow due to a thermal draft from the secondary combustion chamber 9 into the secondary combustion chamber 11, and the hole 12. Air flows in through the holes 13. Therefore, flame-holding combustion occurs in each of the holes 13, and the fuel is evaporated from the wick 1 by the radiation of the combustion heat and the air flow flowing in from the holes 12.

して二次火炎が形成される。A mixed gas of fuel and air is sucked from the primary combustion chamber 9 into the secondary combustion chamber 11 while being mixed with the air flowing in through the gap 16 . Then, a secondary flame is formed using the tips of the outer tube 14 and the inner flame tube 7 as flame ports.

この状態で火炎は安定化し、良好な燃焼かえられる。In this state, the flame becomes stable and good combustion is achieved.

ため火炎は酸欠失火する。Next, the operation when extinguishing a fire will be explained. Extinguishing the fire is performed by lowering the wick 1 using an operating mechanism (not shown). Since the lamp wick 1 is lowered and positioned below the gap 6 formed by the inner #J4 and the wick guide tube 6, the lamp wick 1 is not heated and the evaporation of fuel is drastically reduced. Therefore, flame-holding combustion in the hole 13 becomes a lift flame, resulting in candle combustion at the tip of the wick 1. However, since there is no air supply port in the gap 6, the flame misfires due to lack of oxygen.

しない。However, as the wick 1 descends, the wick mounting bracket 2 also descends. When the wick fitting 2 is lowered, the fuel 3 in the sill 18 is compressed by the enlarged portion 17 of the wick 11X ft fitting 2, and is ejected from the gap 16 to the tip of the wick. The sensible heat of this ejected fuel rises to the tip of the lamp wick 1 or the wick guide tube 6. Since the inner wall of the inner chamber 4 is rapidly cooled, vaporization of the fuel due to residual heat is suppressed. Therefore, the time from extinguishing operation to misfire is short and stable, and the generation of unburned gas after misfire is extremely small, causing no air pollution or odor.

め、安全性の高いものとなる。As described above, according to the present invention, when extinguishing a fire, the amount of unburned gas generated after a misfire can be extremely reduced, and the temperature of each part can be rapidly cooled, so that odor can be prevented when extinguishing a fire. In addition, this eliminates the need for ventilation when extinguishing fires, resulting in energy savings.Furthermore, the fire extinguishing time can be reduced to an average of -K9gM, resulting in high safety.
