より燃焼し、消火が長くかかることがあつた。 In other words, the extinguishing operation of a wick-type liquid fuel combustion device involves lowering a wick with its tip located in the combustion chamber between the inner and outer flame tubes, which has porous holes, between the inner tube and the wick guide tube, thereby reducing the heat transfer to the wick. This drastically reduces the supply and eliminates the air supply, causing a lack of oxygen and a misfire. Even after the wick was lowered, air remained between the inner tube above the wick and the wick guide tube, and the flame did not go out until this air disappeared. In particular, when a flame is about to misfire, it becomes partially flame-holding only in a part of the wick, and an upward air current due to thermal draft occurs directly above the flame, while air flows downward above the wick where there is no flame. The flame did not go out for a long time. Therefore, methods of providing a damper that shuts off the combustion chamber and the wick at the same time as the wick descends, and methods of providing a hole in the upper part of the inner cylinder or the outer wick cylinder have been considered. When the air was shut off by the damper, the fuel gas that evaporated afterwards was not combusted, resulting in a large amount of odor. In addition, by providing holes all around the upper part of the inner cylinder, when the wick is lowered, flame-holding combustion is carried out in the hole, and the above-mentioned flame is held in a part of the wick, which prevents air from flowing down. The generated fuel was combusted by this flame-holding combustion, thereby preventing the generation of odor and unburned gas. However, since the gap between the inner cylinder and the core guide cylinder and the outside communicate with each other through a hole,
Combustion continues until the combustion gas concentration falls below a certain level and the flame holding in the hole lifts and misfires. Therefore, when using a wick with a reduced fuel evaporation capacity or a wick that is exposed to the combustion chamber at a large height, it retains a large amount of heat during combustion, so the amount of fuel that evaporates after falling during extinguishing is large. The fire was not extinguished for a long time. In addition, when a lamp falls over, the fuel that flows out of the wick is combusted by the air that enters through the hole, and it sometimes takes a long time to extinguish the fire.

生が少なく、臭気の発生が著しく少ない。 Next, the operation will be explained. The lamp wick 1 is raised to expose its tip to the primary combustion chamber 9. The fuel 2 passes through the wick 1 and is sucked up to its tip by capillary action. 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 primary combustion chamber 9 into the secondary combustion chamber 11, and the primary combustion chamber 9
Air flows into the holes 12 and 13. Therefore, flame-holding combustion occurs in each of the holes 13, and the radiant heat from the combustion and the air flow flowing in from the holes 12 cause the lamp wick to
The fuel evaporates from the A mixed gas of fuel and air flowing from the primary combustion chamber 9 to the secondary combustion chamber 11 and air flowing from the combustion tube 10 flow into the combustion tube 10, form a flame front in the combustion tube 10, and the combustion tube is heated by combustion heat.
0 is red hot. Then, heat radiation due to the red heat of the combustion tube 10 is radiated to the outside through the transmission tube 15. In this state, the flame becomes stable and good combustion continues.
Next, the operation at the time of extinguishing the fire will be described with reference to FIG. 2, which is a partially enlarged view of FIG. 1. Extinguishing the fire is performed by lowering the wick 1 using an operating mechanism (not shown). As the wick 1 is lowered, it is located below the gap 6 formed by the inner tube 4 and the wick guide tube, so the wick 1
is no longer heated, and fuel evaporation is drastically reduced. Therefore, the stomatal combustion in the hole 13 causes a lift misfire, and the flame moves to the hole 16 provided in the inner cylinder 4, where stomatal combustion is performed by the air in the gap 6 and the space 18 and the evaporated fuel from the lamp wick. If there is no hole 16, as the wick 1 descends, flame-holding combustion occurs in a candle-like manner at the tip of the wick 1, and the heat from this combustion causes continued evaporation of the fuel, and when the amount of combustion becomes small, the flame is spread only to a portion of the wick 1. Due to the upward flow caused by thermal drift in the flame part, air descends above the wick 1 where there is no flame, supplying oxygen to the flame, and it takes a long time for it to misfire. However, according to the present invention, the extinguishing hole 16 communicates the gap 6 with the space 18, and allows the combustion gas evaporated from the wick 1 to flow into the space 18 from the lower hole 16, and after mixing with the air in the space 18. It is ejected from the upper hole 16. For this reason, stomatal combustion occurs in the holes 16 provided in the inner cylinder 4, which further promotes a reduction in the amount of fuel evaporation without creating a flame in the wick 1. Since a uniform combustion heat draft is generated all around the 6, no air convection occurs. Therefore, new air is not supplied and the gap and space 1
Only the air amount of 8 is involved in combustion and misfire occurs. Therefore, the amount of fuel evaporated after the wick 1 is lowered is small, and the amount of air involved in combustion is limited to a minimum, resulting in a short extinguishing time. In addition, by blocking the air involved in stomatal combustion from the outside using the partition tube 17, the amount of air can be limited, preventing stomatal combustion from occurring for more than a certain period of time, and extending the extinguishing time due to the phenomenon where flame remains in some areas. does not occur. On the other hand, if the holes 16 are in communication with the outside, such as during a fall or a headwind, the flame may not be extinguished due to fuel leakage or air flow.
By blocking the fire with the partition tube 10, there is no leakage of fuel or air from the hole 16, and the fire can be extinguished quickly. In addition, by providing a plurality of holes 16 above and below, during flame-holding combustion in the holes 16, the lower hole 16
The inflow of combustion gases (CO 2 , H 2 O, O 2 ) stably causes air to flow out from the upper hole 16 for a certain period of time, stabilizing combustion and improving the stability and uniformity of extinguishing time. Further, since the fuel gas evaporated from the lamp wick 1 is burned to the flammable limit, less unburned gas is generated after extinguishing the lamp, resulting in significantly less odor.

く安全性を高めるものとなる。 As described above, according to the present invention, the closed space communicates with the movable space of the lamp wick through the plurality of holes provided above and below, so that when extinguishing a fire, the fuel gas flowing in from the hole at the bottom mixes with the air in the space. Since the fuel is ejected from the hole at the top, flame-holding combustion occurs for a certain period of time, reducing fuel evaporation extremely quickly.The amount of supplied air leading to a misfire can be set to the minimum, so the extinguishing time from extinguishing action to misfire is stabilized. It can be made shorter. In addition, this reduces the amount of unburned gas generated when extinguishing a fire, reducing the odor during extinguishing, making it more comfortable, and since the wick passage does not communicate with the outside, fuel will not leak out even if it falls over. This improves safety.
