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. Also, 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 forms near the fire pans G and H and blows out the flame. This shortens the extinguishing time.

However, this had the following problems.

In other words, at the time of the fall, the vaporized gas in the chamber E gathers at the bottom of the chamber E, and the flame that remained in the wick storage space without being extinguished by the explosion extinguishing propagates, continuing to burn slowly, that is, the extinguishing time increases. I had a long problem.

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.

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 at the upper part of the guide tube 3, and this opening 5 is closed by the wick 4 when the wick 4 is raised as shown by the broken line and is being burned, and when extinguished, the opening 5 is closed by the solid line as shown in the solid line. As shown, the lamp wick 4 is lowered below the opening 5 between the guide tubes 2 and 3, so that it 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, 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 to be performed, the lamp wick 4 is raised as shown by the broken line so as to enter the lower part between the inner and outer flame tubes 10 and 11, and is then 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 mix in the chamber 6 and explode instantly, and this blast blows out the flame near the fire pans 13 and 14, instantly extinguishing the fire. That's what I do.

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 due to the draft effect flows into chamber 6 as shown by arrow A.
The vaporized gas from the wick 4 flows in as shown by arrow B due to its weight.
This mixes.

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 only burn between the plates 7a and 7b, and the extinguishing time will not be extended. Note that this is the same even if there are no holes 8, but it is more advantageous to have holes 8 in terms of burning the mixed gas between the plates 7a and 7b as quickly as possible.

As described above, according to the present invention, the fire extinguishing time does not become long in the event of a fall, resulting in high safety.
