Abstract

PURPOSE:To make a short fire distinguishing time uniform and improve a safety in case of fall of a burner by a method wherein a flame plate on which an inner flame cylinder in a wick guide column is composed of a flame plate movable in a vertical direction. CONSTITUTION:The fire plate 14 which can be moved vertically is moved along a moving guide due to the operation in which a chimney pressing it is removed and fallen simultaneously with a fall of a burner, and the flame plate 14 and the wick guide column 7 make a clearance. Due to this arrangement, the flame is kept at the extremity end of the flame plate 14 under air flowing from this clearance. Even when the flame is held at a part of the wick 1, the air for keeping flame is not supplied to the extremity end of the flame plate 14 at the upper part of the wick 1 having no flame and then the combustion at the wick 1 is eliminated. With this arrangement, flame is scarcely formed at the wick outer cylinder 6 containing fuel and the wick 1, so that a supplying of heat required for evaporating the fuel is rapidly decreased and evaporation volume of fuel is also rapidly decreased to enable the fire distinguishing time to be stabled.

Low combustion noise, simple configuration and easy operation;
It can be easily moved. Ignition, combustion amount adjustment, and extinguishing are controlled by moving the wick up and down to control fuel evaporation. When igniting, the wick is raised to face the combustion chamber, and the high-temperature flammable part is brought close to the wick to begin combustion. To control the amount of combustion, move the wick up and down to change the evaporation area of the fuel and increase or decrease the amount of combustion. To extinguish the fire, move the lamp wick downward using a rack and pinion, reduce the amount of fuel evaporation due to the drop in temperature of the lamp wick, and stop combustion due to flame lifting and misfire. For safety reasons, if a wick burner vibrates or falls over, the wick is instantly lowered by a spring or other force to extinguish the fire. This configuration is possible because by lowering the wick, the distance between the hot part and the wick increases, and due to cooling, the amount of fuel evaporation from the tip of the wick is drastically reduced, and because the flame is held in the wick just before extinguishing, the flame is held close to the wick. By reducing the amount of oxygen in the fuel, it will cause a misfire. However, just before a misfire, the cylindrical wick held its flame in some parts, so air flowed down from the part of the wick where there was no flame, making it uneven and took a long time to extinguish the flame. For this reason, there have been proposed means for providing several holes in the core guide tube or outer core tube, and means for providing a slit-like gap at the portion where the inner tube and the core guide tube contact. The means of providing several holes in the wick guide tube or the wick outer tube allows the holes V to hold the flame when extinguishing, prevents the flame from being held in a part of the wick, and speeds up the evaporation of the wick to shorten the extinguishing time. However, when the lamp falls over, there is a risk that the fuel will flow out of the hole and cause a fire.While the lamp is burning, the hole is closed with a wick, but due to the deformation of the wick, air randomly flows in, causing a change in combustion; However, it causes a change in calorific value, flames, and odor 2>. In addition, the method of providing a slit-shaped gap at the part where the inner flame tube and the wick guide tube come into contact prevents the flame from being held in the wick by holding the flame in the slit-shaped gap when extinguishing the lamp, thereby speeding up the extinguishing time. However, the amount of air flowing in from the gap during combustion made the flame holding at the bottom of the inner flame tube unstable, causing fluctuations in the amount of combustion and the generation of odors.

である。Structure of the Invention The present invention comprises a fire pan plate that allows the fire pan on which the inner flame tube of the wick guide cylinder is placed to be moved up and down, so that when the burner falls over, the inner flame tube and the outer flame tube fly out from the fire pan. The movable fire pan plate forms a slit-shaped gap with the upper part of the core guide cylinder. By holding the flame in the slit-like gap between the slits, it prevents the flame from reaching the wick and extinguishes the fire quickly.

It is mounted so that it can move up and down in the gap formed by the outer cylinder 6 and the core guide cylinder 7 (the operating mechanism is not shown). A cylindrical porous tube 8 having a larger porosity than the outer flame tube 4 is provided on the upper part of the outer flame tube 4, and the inner flame tube 3 and the porous tube 8 form an upper part of the flame combustion chamber 5. It constitutes a secondary combustion chamber 9.

量の増減と、灯芯１の露出面積の増減により変化する。Fuel 2 passes through the lamp wick 1 and is sucked up to its tip by capillary action. When the lamp wick 1 sufficiently soaked with fuel is lifted up, exposed to the primary combustion chamber, and ignited, an ignition eye is created at the tip of the lamp wick 1 and combustion begins. When the high-temperature gas from combustion passes through the primary combustion chamber 5 and the secondary combustion chamber 9, a thermal draft is generated and the air necessary for combustion flows through the holes A17 of the inner flame tube 3, the outer flame tube 4, and the holes of the porous tube 8. It flows in from B18. Evaporation of the fuel changes depending on an increase or decrease in the amount of air flowing in from the hole A17 of the inner flame tube 3 or outer flame tube 4, and an increase or decrease in the exposed area of the lamp wick 1.

火炎は孔Ａ１７において気孔燃焼しこの気孔燃焼は灯芯
１に燃料の蒸発熱を供給する。The flame performs stomatal combustion in the hole A17, and this stomatal combustion supplies the lamp wick 1 with the heat of vaporization of the fuel.

燃料はガスとなり１間隙より外部へ流出する。When the burner falls sideways, the chimney including the inner flame tube 3 and the outer flame tube 4 fly away from the core outer tube 6 and the core guide tube 7. Therefore, the core outer cylinder 6 and the core guide cylinder 7 are exposed to the atmosphere. When the lamp wick 1 falls down, it is lowered by the force of a spring (the vibration sensor (spring not shown)) and is located at the lower part of the gap between the wick guide tube 7 and the outer core tube 6. However, since the upper parts of the wick guide tube 7, the wick outer tube 6, and the tip of the wick 1 were at high temperatures, the heat caused the fuel that adhered to the upper part of the wick guide tube 7, the wick outer tube 6, and the fuel impregnated in the tip of the wick 1 to become gas. Then, it flows out from the first gap.

Since the chimney that was holding it down separates and falls over, it moves along the moving guide, creating a gap between the fire pan plate 14 and the core guide tube 7.

くなりかつ均一化する。Therefore, the air flowing in from this gap causes the fire pan plate 14 to
Even when the flame is held at the tip of the wick 1 and the flame is held at a part of the wick 1,
Since flame-holding combustion occurs at the tip of the fire pan plate 14 above the lamp wick 1 where there is no flame, air flows down and is not supplied, resulting in a misfire in the combustion in the lamp wick 1. The same applies to the case of the outer core cylinder 6. For this reason, after the fall, almost no flame is formed in the wick outer tube 6 and the lamp wick 1 that contain the fuel, so the supply of heat necessary for evaporating the fuel is drastically reduced, the amount of fuel evaporated is rapidly reduced, and the fuel concentration becomes lighter. The time until the lift misfires is shortened, and the extinguishing time is stable because the flame is always maintained at the tip of the fire pan plate 14 in the same state. In addition, since the inflow path for air into the secondary combustion chamber 5 is only the hole A17 that normally performs pore combustion of the inner flame tube 3 and outer flame tube 4 during combustion, flame stability is stable and changes in combustion amount and odor are prevented. There is no risk of backfire to the outside, and no standing flames occur. Moreover, if the fire pan plate 14 is pushed up with an elastic body 16 spring, rubber, etc. that is smaller than the weight of the combustion tube including the inner flame tube 3, outer flame tube 4, etc., it will fall and the combustion nodes will fly away from the fire pan plate 14 and at the same time. Since the gap between the fire pan plate 14 and the upper part of the wick guide tube can be provided constant, the extinguishing time can be further shortened and made uniform.

This improves safety by uniformly shortening the extinguishing time, and prevents the risk of flames, odor generation, and backfire phenomena without causing any change in the amount of combustion. In addition, at the top of the core guide tube, the heat resistance increases due to the contact between the core guide tube and the inner flame tube through the fire plate, and the temperature of the core guide tube decreases.
Changes in the amount of combustion caused by tar adhering to the lamp wick and inconveniences caused by vertical movement of the wick can be reduced.
