Abstract

PURPOSE:To reduce an offensive smell generating at the time of usual extinguishment of a burner fire by a method wherein the downward stroke of a wick at the time of usual extinguishment of the fire is made shorter than that at the time of emergency extinguishment of the fire. CONSTITUTION:A first stop member 13 for stopping at a predetermined position an adjusting shaft 9 connected to the wick 1, a fire extinguishing button 6 for releasing the engagement of the stop member with the shaft 9 and a second stop member 14 for stopping the adjusting shaft 9 released from the first stop member 13 while the shaft takes a rotary return motion, are provided. Further, the downward stroke of the wick 1 at the time of usual extinguishment of fire by the fire extinguishing button 16 is made shorter than that at the time of the emergency fire extinguishment. When the button 16 is pushed down at the time of usual fire extinguishment, the first stop member 13 is raised to rotate a fire extinguishing gear 10 until the gear 10 engages the second stop member 14. Thus, in the case of the usual fire extinguishment, since the tip of the wick is kept slightly lower than a fire grate (e), there is a plenty of air above the wick 1 and the temperature of a wick guide inner cylinder 2 located near the fire grate (e) is high so that the time of vaporization of the oil from the wick 1 is prolonged and the fire extinguishing time becomes longer.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the reduction of odor during normal extinguishing of oil combustors. Conventional methods for extinguishing lights by lowering the wick include a method that instantly extinguishes the light using a vibrating fire extinguishing device, and a method that extinguishes the light by rotating the wick up and down adjustment knob. The above method is easier and more convenient to extinguish a fire, but it is better to extinguish it quickly (10
(within seconds), so the odor is strong. This is because the temperature in the wick housing is high, so the kerosene vaporizes from the fallen wick and decomposes in the hot combustion tube, causing odors such as acetaldehyde. The present invention addresses this issue. 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 portions on the inside and outside, the core guide tube 2 is connected to the lower tank 4, and the core outer tube 3 is connected to the upper tank 6 via the tank packing 6.
It is fixed at 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 claws, and a wick upper and lower metal fitting 8 having a rack portion is welded to this metal fitting 7, passing through the lamp wick 1.

An adjustment shaft 9 having a pinion part is fixed to the front part 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 ordinary claw part a of the fire extinguishing gear 100 is the lever 13 used as the first locking body of the vibration fire extinguishing system.
The pawl b, which is abutted against and locked by the lever 14, which has become one step higher, comes into contact with and is locked by the lever 14 used as the second locking body.This point will be described in detail later.

A shaft 17 of a fire extinguishing button 16 is passed through the vibration extinguishing body 16 of the vibration fire extinguishing system, and the right side of the lever 13° 14 is pivotally supported by this shaft 17, and a torsion spring 18 is inserted into this shaft 17. The lever 13 is urged toward the fire extinguishing gear 19 side. Also, the left side of the extinguishing button 16 is the bottle 19. It extends downward to accommodate the bin 2o. This bottle 19. Bin 2C
It is for pushing down and lifting up the lever 13.

A weight part 21 is movably attached to the right 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, the knob 11 is turned clockwise and set 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, the bottle 2o is lifted up using the shaft 17 that presses the fire extinguishing button 16 as a fulcrum, so the lever 13 is lifted and the claw a of the fire extinguishing gear 1o is disengaged to extinguish the fire. Due to the bias of the spring 12, the adjustment shaft 9 is rotated to the left, and the raised claw part is moved to the lever 1.
4 and stops. This state is normally extinguished. In addition, when extinguishing, the tip of the wick 1 is sunk shallower (10 to 16 N) than the fire pan e of the wick outer cylinder 3 and the wick guide tube 2, so there is air in the upper part, and since it is close to the fire pan e, the wick outer cylinder 3. Core guide tube 2
Since the temperature of the lamp is also high (approximately 100"C), the vaporization from the wick 1 is prolonged, and the extinguishing time becomes longer (90 to 200 seconds). When the fire is extinguished, it is in a state where the flame is spinning in the fire pan e. Therefore, there is not enough heat to warm the combustion tube, the core and outer tubes, and the core guide tube 2, so air flows into the combustion tube through the draft through the core guide tube 2, and it is rapidly cooled (1 minute and 30 seconds TMAX section 700
'C to 400"C or less), and when the fire is extinguished, the temperature that decomposes the kerosene vaporized from the wick 1 (5oO to 700"C)
The odor during extinguishing is greatly reduced.

5 and 6 show an emergency fire extinguishing situation. When the weight part 21 of the vibration fire extinguishing device falls down due to vibration, the left end of the lever 14 is lifted by the collar f of the weight part 21, and the lever 14 above it is lifted up.
is also lifted, so both the claws a and b of the fire extinguishing gear 10 come off.
The tip of the wick 1 descends to the extinguishing stroke (20 to 241!11 below the fire pan e), and due to the effect of the small hole q on the top of the wick guide tube 2 of the conventional technology, air suddenly flows into the accommodating section 8, and the wick guide tube The fire is extinguished instantaneously (within 10 seconds) due to a drop in the temperature of the 2° wick outer cylinder 3, dilution of vaporized kerosene from the wick 1, etc.

This is the same as conventional instantaneous extinguishing, as the temperature of the combustion tube is high.
After extinguishing the kerosene, vaporized gas from the wick 1 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 claws a and b provided on the fire extinguishing gear 10
Although it is configured so that it can be locked in two stages by changing the size of the lever, for example, by providing separate fire extinguishing gears corresponding to each of the levers 13 and 14, it is possible to lock in two stages. Any configuration may be used as long as two-stage locking is possible.

As can be seen from one or more embodiments, 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. be.
