Abstract

PURPOSE:To enable to extinguish fire in a short period of time at the time of emergency extinguishment by reducing a nasty smell at the time of normal fire extinction, by a method wherein a descending position of a wick at the time of extinguishment is set up at more than at least two stages and a protruded part is provided upward at least on a part of a fuel evaporating part of a wick. CONSTITUTION:Normal evaporation and combustion of fuel are done by exposing a fuel evaporating part 12 within a combustion chamber 5 up to an A position by a wick 10 contained risably and fallably within a wick containing cylinder space 11 to be formed between an internal and external wick containing cylinders 6, 7 and the fuel evaporating part 12 is made to descend to either a B position or a C position at the time of extinguishment. A protrusion 13 is provided by protruding upward by (a) in dimension, a height of the tip of the protrusion 13 is set up so that the wick 10 is not exposed within the combustion chamber when the wick 10 is descended down to the upper descending position B. A ventilating hole 14 provided on a circumferential wall of the external wick containing cylinder 7 is set up at a position becoming lower than the upper descending position B and upper than the lower descending position C. The diameter of air holes 15 provided close to the protrusion 13 among air holes 4 provided close to the fuel evaporating part is made larger than the other one.

Always extinguish fires on the same occasion □9. This tendency was strong in what was being done in Japan. In order to solve this problem, the lower dimension 1'If of the moon center of emergency fire extinguishing 11, 1 is made to be smaller than the lower dimension of normal fire extinguishing IRi. 181 What about Tuesday? 1"!l There is a method to suppress the odor by reducing the fire time as much as possible, and to extinguish the fire as quickly as possible in an emergency fire extinguishment, but with this method alone, the extinguishing time varies considerably and is not necessarily satisfactory. However, there is a method to provide a ventilation hole in the wick storage cylinder that collects the wick, and to provide a mechanism that closes this ventilation hole during normal extinguishing and opens it during emergency extinguishing, but the mechanism is complicated and requires processing and processing. There was a cost issue.

In FIGS. 1 and 2, 1d is an inner flame tube, 2 is an outer flame tube, and 3 is an outer flame tube.The three components are arranged in order in a substantially concentric manner. The broken inner flame tube 1 and outer flame tube 2 have a large number of air holes 4, and air is introduced into the combustion chamber 5 formed at t and i-l, where combustion is performed. 6 and 7 are inner core housing cylinders, respectively;
The upper ends of the outer core housing tube form an inner flame tray 8 and an outer flame tray 9, respectively, and the inner flame tube 1 and the outer flame tube 2 are placed on the inner flame tray 8 and the outer flame tray 9, respectively. There is. The lamp wick is vertically movably stored in the wick housing space 11 formed between the inner and outer core housing tubes 6°7. The fuel vaporizing section 12 is exposed in the combustion chamber 5 at the A position to vaporize and burn the fuel R1, and when extinguishing the fire, it is moved to either the 8th position or the C position. In addition, a part of the fuel vaporization section is provided with a protruding part 13 having a dimension of a length above, and its tip is set at a height such that it will not be exposed inside the combustion chamber when the lamp wick 1o is lowered to the lowering position B. It is set. A through hole is provided on the 7th circumference 9 of the 14-piece outer core storage cylinder.
'/'ii'' - lower than iB, 11 on the F side, 1 - lower position C' is set to one of the positions. 15 Protruding portion 13 of the hole 4 provided near the solvent vaporization section
This air hole 15 is provided nearby and has a larger diameter than other parts. In the following explanation, ii? Extinguish the fire, and use the lower descending position as an emergency fire extinguisher.

、燃料ガスも多く発生する。''-In the structure, when the lamp is normally extinguished, the descending dimension of the wick 10 is small, so the temperature of the inner and outer wick housing tubes 6, 7 and the fuel vaporization section 12 remains high for quite a long time even after the extinguishing operation, and the fuel gas also occurs frequently.

ノ由りである。However, since a part of the fuel vaporization part 12 is provided with an upwardly protruding part 13, a small flame remains in this part for a long time.
Since the generated fuel gas can be combusted by this flame, the irritating odor caused by unburned gas is greatly reduced. FIG. 3 shows a liquid fuel combustion system according to an embodiment of the present invention @(
a) and conventional example (normal fire extinguishing and emergency fire extinguishing have the same mechanism)
The odor measurement in (b) was carried out using a five-stage sensory test method, and the average value is shown. Further, the conditions at that time are as shown in the table below.

ので臭気如かなり低減される。Margin below In conventional examples, the extinguishing time is short, and the temperature near the wick is steep; τ does not decrease, so fuel and gas are generated, which increases the odor. However, in this embodiment, a flame is formed in the protrusion provided in the -fuel gamma 1 vaporizing section 12 and the generated fuel gas is combusted, so that the odor is considerably reduced.

１０によって閉塞されており、何ら作用しない。By making at least one of the air holes 15 in the inner and outer flame tubes near the protrusion 13 larger than the other, more air can enter the vicinity of the protrusion 13. It is said that a stable flame is formed in this area. In addition, the protruding part 13 tip (d)
It is set at a height that prevents the inside of the fire from being exposed, making it possible to completely extinguish the fire. In other words, if the tip of the protrusion 13 is not exposed to the combustion chamber 5, the flame that forms after the extinguishing operation is not directly formed on the protrusion 13, but is vaporized from the protrusion 13. Fuel or air hole 15
The combustion chamber 50 is combusted at the lower end of the combustion chamber 50 by being supplied with air. Therefore, after the extinguishing operation, the temperature near the inner and outer core housing cylinders 6.7 and the protruding portion 13 decreases, and the vaporization of the burner X-1 ceases, completing the seven fires. (7 pieces, protrusion 13
If i, t*: protrudes into the combustion chamber 5, the protrusion 13
Air is supplied directly to the flame, forming a flame here. Therefore, the degree of 7y1' of the protruding portion 13 is difficult to lower, and there is a risk that the fire will not be extinguished even if the fire extinguishing operation is performed. Therefore, it is necessary to set the protrusion 13 at a height that does not expose it to the combustion chamber 5 during normal fire extinguishing. Unfortunately, when the fire is normally extinguished, the tip of the wick 10 is located on one side of the ventilation hole 12, so it is blocked by the wick 10 and has no effect.

Since the temperature of the fuel vaporization section 12 is maintained at a relatively low temperature, the temperature drops rapidly to 11 degrees Celsius, and the vaporization of the burnt block 1 quickly stops, so that extinguishing can be quickly completed. Furthermore, by providing a ventilation hole 14f as shown in FIG.
Since air is pumped into the core housing cylinder space 11, the temperature near the cylindrical part 12 is quickly lowered ((,
It is possible to quickly burn out the 1 gas that is generated (9), and to quickly extinguish the fire by relaxing the 5 gas, as the 1 gas that has not completely burnt out will be lost. .

By cutting out the parts, the following effects can be obtained.
