Description

[Detailed description of the invention] The present invention relates to liquid fuel combustors.

A conventional example is shown in FIG.

In this conventional lamp, cylindrical guide tubes A and B are provided, and a cylindrical lamp wick C is provided between the guide tubes A and B so as to be vertically movable.

The guide tube is also provided with an opening D that is closed by the wick C when the wick C rises as shown by the broken line to perform combustion, and is opened when the wick C descends as shown by the solid line to extinguish the fire. A ring-shaped chamber E is provided outside the opening D, and this chamber E is provided with holes F around the entire circumference through which air flows during extinguishing.

In the above configuration, in order to carry out combustion, the lamp wick C is raised as shown by the broken line, and combustion is carried out in a combustion tube (not shown) placed on the fire pans G and H. When extinguishing a fire, lower the wick C between the guide tubes A and B as shown by the solid line to extinguish the fire.

When extinguishing this fire, the vaporized gas from the wick C and the air from the hole F mix in the room E and explode instantly, and this blast blows out the flames formed near the fire pans G and H. This shortens the extinguishing time.

However, this had the following problems.

In other words, when a person falls down, the vaporized gas in room E gathers on the lower side of chamber E, and the flame that remains without being completely extinguished by explosive extinguishing spreads and burns slowly, which means that the time it takes to extinguish the gas becomes longer. It was hot.

Therefore, the present invention attempts to solve the above-mentioned conventional problems by dividing the room into a plurality of parts in the circumferential direction and providing a porous member between the plate and the opening.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In Figures 1 to 3, 1 is a fuel tank;
A cylindrical guide tube 2 is inserted through the center of this tank 1.
has been erected.

Further, cylindrical guide tubes 3 are provided on the outer periphery of the guide tube 2 at predetermined intervals, and a cylindrical lamp wick 4 is provided between these guide tubes 2 and 3 so as to be vertically movable.

Further, a ring-shaped opening 5 is provided in the upper part of the guide tube 3, and this opening 5 is closed by the lamp wick 4 when the lamp wick 4 is raised as shown by the broken line.
When extinguishing a fire, the wick 4 is connected to the guide tube 2, as shown by the solid line.
3, it is lowered below the opening 5 and is opened.

Further, a ring-shaped chamber 6 is provided on the outside of the opening 5 on the opposite side of the lamp wick 4, and within this chamber 6 is a second
As shown in the figure, a plurality of plates 7 are provided so as to divide the inside of this chamber 6 into a plurality of parts in the circumferential direction. Further, a ring-shaped porous member 15 made of wire mesh is provided between the plate 7 and the opening 5 at a predetermined distance from the opening 5. Further, each divided chamber 6 is provided with a hole 8 through which air flows.

Note that 9 indicates an inner flame tube 10, an outer flame tube 11, and an outer flame tube 12.
It is a combustion cylinder made of

In the above configuration, when combustion is performed, the wick 4
The flame is raised to enter the lower part between the inner and outer flame cylinders 10 and 11 as shown by the broken line, and is ignited to cause combustion.

To extinguish the fire, the lamp wick 4 is lowered from the opening 5 between the guide tubes 2 and 3 as shown by the solid line, thereby extinguishing the fire.

In this case, the vaporized gas from the wick 4 and the air flowing in from the hole 8 are mixed in the chamber 6 and explode instantly, and this explosion blows out the flame in the vicinity of the fire pans 13 and 14, making it possible to extinguish the fire instantly. I have to.

Now, even when the lamp falls due to an earthquake or the like, the wick 4 is lowered before it falls as shown in Figure 2, and the fire is extinguished.

Figure 3 shows the state after the fall, and shows the hole 8 at the bottom of the fall.
From a, air flows into the chamber 6 as shown by arrow A due to the draft effect, and vaporized gas from the lamp wick 4 flows in as shown by arrow B due to its weight, and these are mixed.

In this case, since the chamber 6 is divided into a plurality of parts by the plate 7, the mixed gas does not circulate inside the chamber 6.
Therefore, even if a flame remains for some reason and ignites, it will burn between 7a and 7b, and the extinguishing time will not be extended. Also, since there is a porous member 15 between the opening 5 and the plate 15, the chamber 6 outside the porous member 15 for the ember
Inward ignition is prevented by the porous member 15, and this also does not increase the extinguishing time. Note that this is the same even if there is no hole 8, but the plate body 7
The presence of holes 8 is advantageous in that the mixed gas between a and 7b is combusted as quickly as possible. As described above, the present invention is safe.
