Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the reduction of odor during normal extinguishing of oil combustors. Conventional methods of extinguishing lights by lowering the wick include a method of instantly extinguishing the light using a vibrating fire extinguisher, and a method of extinguishing the light by rotating the wick up/down adjustment knob. The above method is easier and more convenient to extinguish, but it extinguishes quickly (within 10 seconds) and has a strong odor. This is because the temperature in the wick storage area is high, so the kerosene vaporizes from the fallen wick and decomposes in the still hot combustion tube, causing odors such as acetaldehyde. The present invention makes the wick lowering stroke during normal extinguishing using the fire extinguishing button shorter than the wick lowering stroke during emergency extinguishing when vibration is detected, thereby significantly reducing extinguishing odor during normal extinguishing. An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. 1 is a cylindrical lamp wick. Also, of the core guide tube 2 and the core outer tube 3 that form core housing parts inside and outside, the core guide tube 2 is fixed to the lower tank 4 and the core outer tube 3 is fixed to the upper tank 6 via the tank packing 5. There is. The upper tank 6 and the lower tank 4 are welded together. A cylindrical wick fixing metal fitting 7 is fixed to the inside of the lamp wick 1 with glue and nails, and a wick upper and lower metal fitting 8 having a rack part is welded to this metal fitting 7, passing through the lamp wick 1. An adjustment shaft 9 having a pinion portion is fixed to the front portion of the upper tank 6 so as to come into contact with this. In addition, a fire extinguishing gear 10 is inserted and fixed in the middle of the adjustment shaft 9, with claws being machined around the periphery so that only a portion of the gear is raised higher. Furthermore, a knob 11 is inserted into the tip of the adjustment shaft 9.

Reference numeral 12 denotes a coiled fire extinguishing spring, the lower end of which is fixed to the upper and lower wick fittings 8, and the upper end of which abuts against the flat surface of the wick outer tube 3 to constantly urge the lamp wick 1 downward. The normal claw portion a of the fire extinguishing gear 10 is brought into contact with and locked to the lever 13 used as the first locking body of the vibration fire extinguishing device,
The raised claw b comes into contact with and is locked to the lever 14 used as the second locking member, and this point will be discussed in detail later. A shaft 17 of a fire extinguishing button 16 is passed through the vibration extinguishing body 15 of the vibration fire extinguishing system, and the right side of the levers 13 and 14 is pivotally supported by this shaft 17, and a torsion spring 18 is inserted into this shaft 17.
is biased toward the fire extinguishing gear 10 side. Further, the left side of the fire extinguishing button 16 extends downward to provide pins 19 and 20. These pins 19 and 20 are used to push down or lift up the lever 13. A weight part 21 is movably attached to the left part of the lever 14 through a hole c, and serves as a vibration sensing part.

Next, to explain the operation and function, when igniting, turn the knob 11 clockwise and set it by a little less than one turn as shown in Figures 1 and 2. In this state, the ignition heater (not shown) is used to turn the lamp wick 1 on. ignite. Then, combustion starts with the air from the small hole d of the outer core tube 3, and normal combustion occurs in the combustion tube (not shown) installed above the core outer tube 3 and the core guide tube 2. Normally, when extinguishing a fire, as shown in Figures 3 and 4, when the fire extinguishing button 16 is pressed, the pin 20 lifts up using the shaft 17 as a fulcrum, the lever 13 is lifted, and the claw a of the fire extinguishing gear 10 is released, extinguishing the fire. Due to the bias of the spring 12, the adjustment shaft 9 rotates to the left, and the raised claw portion b comes into contact with the lever 14 and stops. This state is normally extinguished. In addition, when extinguishing the fire, the tip of the wick 1 is sunk shallower (10 to 15 mm) than the fire pan e of the wick outer cylinder 3 and wick guide tube 2, so there is air in the upper part, and since it is close to the fire pan e, the tip of the wick is Since the temperatures of the tube 3 and the wick guide tube 2 are also high (approximately 100 degrees Celsius), vaporization from the wick 1 takes longer, resulting in a longer extinguishing time (90 to 200 seconds). When extinguishing a fire, the flame is spinning around in the fire pan e, so there is not enough heat to warm the combustion tube, wick outer tube 3, and wick guide tube 2, so the combustion tube is drafted through the wick guide tube 2. Air flows in and is rapidly cooled (1 minute
700℃ to 400℃ at maximum in 30 seconds), and the temperature at which the kerosene vaporized from wick 1 decomposes when the fire is extinguished (500℃)
~700°C) or less, which greatly reduces bromination during fire extinguishing.

Fig. 5 and Fig. 6 show the case of emergency fire extinguishing, and when the weight part 21 of the vibration fire extinguishing system falls down due to vibration, the weight part 2
The left end of the lever 14 is lifted by the collar f of the gear 1, and the lever 13 above it is also lifted, so the fire extinguishing gear 1
Both claws a and b of 0 are disengaged, and the tip of wick 1 descends to the extinguishing stroke (20 to 24 mm below fire pan e).
Due to the effect of the small hole g in the upper part of the core guide tube 2 of the conventional technology, air suddenly flows into the core housing part, and the core guide tube 2,
The fire is extinguished instantaneously (within 10 seconds) due to a drop in the temperature of the wick outer cylinder 3, dilution of vaporized kerosene from the wick 1, etc.
This is the same as in conventional instantaneous extinguishing, and since the temperature of the combustion tube is high, the vaporized gas of kerosene from the wick 1 after extinguishing is decomposed and a pungent odor is generated. However, this odor will not be a problem in case of an emergency such as an earthquake.

In the above embodiment, the fire extinguishing gear 10 is configured so that it can be locked in two stages by changing the sizes of the claws a and b. A fire extinguishing gear may be provided to enable two-stage locking, and any configuration may be used as long as two-stage locking is possible.

As can be seen from the above examples, in the present invention, the height of the lamp wick during normal extinguishing is made higher than that during vibration extinguishing to extend the extinguishing time, thereby greatly reducing the extinguishing odor during normal extinguishing. .
