Abstract

PURPOSE:To put out fire without causing back fire, exploding sound, uprising flame, etc., by a method in which a small chamber to be led through a slit is formed on the periphery of a wick-guide cylinder wall and the small chamber is kept in enclosed state. CONSTITUTION:When putting out fire by lowering a wick 11 down to between guide cylinders 12 and 13 manually or by a vibration fire extinguisher, unburned gas present in a wick vertical moving space 17 mostly flows through a slip 19 into a small chamber 18, where an air-deficient state results and fire is put out. By this, no exploding sound and no uprising flame occur. Also, since the edge of the slit 19 provided in the small chamber 18 has a bent piece 19a projecting toward the small chamber 18 side, the back flow and burning of unburned gas flowing into the small chamber 18 in the wick vertical moving space 17 can be prevented, also, since the portion other than the slit 19 of the small chamber 18 is in enclosed state, no back fire occurs even when petroleum in the wick is vaporized through the slit 19.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wick-type oil combustor, which prevents backfire due to the outflow of vaporized gas during combustion, and at the same time prevents the development of standing flames during extinguishing, thereby ensuring safety for each use. - Improved reliability.

Traditionally, wick-type oil combustors have a small hole in the guide tube wall of the wick to shorten the extinguishing time, but during combustion, the oil in the wick vaporizes and flows out from this small hole, causing the vaporized gas to catch fire. I was afraid that it would happen. As another method, as shown in Fig. 3, a small chamber C is formed on the outer periphery of the guide tube B of the lamp wick.
The small chamber C is communicated with the space X above and below the lamp wick via the wick D, and a small hole F is formed in the outer circumferential wall of the small chamber C. In this method, the gas a generated during extinguishing is mixed with the air from the small hole F, and the ignition C from the fire pan causes explosive combustion in the small chamber C, and the blast generated at this time is sent into the space Σ above and below the wick. It is designed to extinguish embers by blowing on them. However, even though this method produces less noise than the above-mentioned method, it also produces a loud explosion sound during the explosive combustion described above, as well as a large flame (standing flame) as shown by G, which can be dangerous for the user. The problem arose of giving people a sense of anxiety.

Therefore, the present invention solves the conventional problems and achieves the intended purpose by forming a small chamber communicating through a slit on the outer periphery of the core guide cylinder wall and keeping this small chamber in a sealed state.

One embodiment will be described below with reference to the drawings.

In Figures 1 and 2, 1 is a rectangular fuel tank;
This fuel tank 1 is erected on legs 3 on a rectangular plate body 2.

The inside of the fuel tank 1 is partitioned into two chambers 6.6 by the cylinder 4, and these two chambers 6, 6 are communicated with each other via the open lower portion of the cylinder 4.

Inside the chamber 6 is a cylindrical lamp wick 11 whose lower end is submerged in oil 8 and whose vaporizing part 9 is moved up and down by a knob.
is provided.

In addition, a cylindrical guide tube 12.1 is provided inside and outside the lamp wick 11.
3 is provided, and serves as a guide when the lamp wick 11 moves up and down.

The wick 11 has inner and outer flame tubes 15 and 16 that constitute the combustion section 14.
It is set up so that you can face the inside.

A large number of static holes are provided in the outer cylinders 16, 16.

Of the guide tubes 12 and 13, the outer and inner tubes 13 are constructed by fitting three tube-closing members 131L, 13b, and 130 into each other, and form a small chamber 18 in the shape of a sealed ring around the outer periphery of the wick vertical movement space 17. are doing. Also, this cylindrical member 131
L, 13b, 13C (7) Among them, 13a and 13b are opposed to each other with a gap in between, and a slit opening 19 is formed over the entire circumference to communicate the small chamber 18 with the wick vertical movement space 17 (this is in a discontinuous state). (also good), in addition -
[--The opening edge of the slit opening 19 is burred on the small chamber 18 side and protrudes toward the small chamber 18 side. It has a bent piece 191L.

In the above configuration, the combustion a#Fi lamp wick 11 is lowered manually or by a vibration extinguishing device into the guide tubes 12, 131fl to extinguish the fire. Part is slit opening 1
The air flows into the small chamber 18 through the air outlet 9, resulting in an air shortage and extinguishing the fire. In other words, there is no explosive combustion like in conventional ones, and there is no explosion sound or standing flame. In addition, unburned gas is about 4 times heavier than air, so when the appliance falls over, most of the unburned gas will remain in the small chamber 18 even if it is lower than the fire pan 20.21 side of the upper end of the guide tube 12.13 or the tip of the wick. There is no possibility that the water will flow in and flow out from the fire pan 20, 21 and continue to burn slowly.

Furthermore, since the opening edge of the slit opening 19 provided in the small chamber 18 has a bent piece 192L that protrudes toward the small chamber 18 side, the mistletoe that has flowed into the small chamber 18 flows back into the lamp vertical movement space 17. There is an advantage that there is less fear of the lamp wick burning, and that the wick side of the slit opening 19 is free of anything that can easily get caught, such as debris, so that the lamp wick 9 can move up and down smoothly.

The small chamber 18 is sealed except for the slit opening 19, so even if the oil in the wick vaporizes through the slit opening 19 during combustion, this vaporized gas will not leak outside. There is no fear of backfire.

The small chamber 18 may have any shape as long as it has a volume larger than the volume of unburned gas produced during extinguishing the fire. In addition, if the opening diij of the slit opening 19 that communicates this small chamber 18 and the space for vertical movement of the lamp wick is too small, it will be difficult for unburned gas to flow in, and if it is too large, it will hinder the vertical movement of the lamp wick. The guide cylinder 13 (S'J SO) opening 19 provided with the slit opening [] 19 was found in the desired location.
is provided in the inner inner cylinder 12, this inner inner cylinder 1
The diameter φ of 2) was preferably within the range of about 0.07 to 0.1.

As is clear from the description of the embodiments above, according to the present invention, it is possible to extinguish a fire without causing backfire, explosion noise, standing flames, etc. due to the outflow of vaporized gas, thereby improving safety and safety for users.
It has great effects, such as being highly reliable and offering particularly elegant safety in the event of a fall.
