火炎を形成する等の課題を有していた。Problems to be Solved by the Invention According to such conventional means, the amount of vaporization is reduced compared to the amount of air supplied when the exposed height of the lamp wick 1 is lowered to reduce the amount of vaporization and combustion. If the amount of combustion in the lower part of the combustion chamber 8 increases and the amount of vaporization is larger than the amount of air, the lower part of the combustion chamber will be in a state of air shortage, and the amount of combustion in the middle and upper part of the combustion chamber 8 will increase. ) Heat the wick 1, the inner fire pan 4, and the outer fire pan 5. Therefore, the amount of heat given to the lamp wick 1 increases and the vaporization area decreases, but the amount of vaporization does not decrease much, and in order to further reduce the amount of vaporization, the exposed height of the lamp wick 1 must be made lower than the fire pan part 4.5. Required, fire pan part 4.5
As the temperature rises further, tar is formed between the parts. wick 1
It takes a long time to extinguish the fire even if you descend and try to extinguish it. When the exposed height of the wick is increased to increase the combustion volume from a state of small combustion volume, the amount of vaporization temporarily becomes excessive, resulting in problems such as the formation of an excessively large flame at the exit of the combustion tube.

減する。Function In the above configuration, the vaporized fuel gas at the bottom of the combustion chamber diffuses and mixes with the air supplied from the air holes of the inner and outer flame tubes, rises inside the combustion chamber while burning, and is impregnated into the lamp wick by the combustion heat. The fuel is heated and then evaporated by air flowing near the evaporation surface of the wick. Since the air flowing upward inside the wick guide tube flows along the inner wall surface of the wick guide tube by the rectifier, the inner fire pan and the wick guide tube in contact with the lamp wick are cooled.
Since the conductive heat from the wick guide tube, which is one of the heat sources for heating the wick, is reduced, vaporization from the non-exposed portion of the wick is suppressed. Therefore, if the exposed height of the wick is high, the exposed part of the wick will be heated and vaporized by the combustion flame and radiant heat from the inner and outer flame tubes near the wick, or if the exposed height is low, the exposed part of the wick will be heated and vaporized by the radiant heat from the combustion flame and the inner and outer flame tubes near the wick. The heat-receiving area of the lamp is reduced, and since there is little vaporization from the non-exposed portion of the lamp wick, the phenomenon that the amount of vaporization is difficult to reduce even if the exposed height of the lamp wick is lowered is significantly reduced.

。In the above configuration, when the lamp wick 1 is ignited, the fuel vaporizes and starts combustion. The fuel is combustion heat and the small hole 11 near the wick 1.
The vaporization continues due to the air flow supplied by the thermal draft generated in the combustion chamber 8, and the air necessary for combustion passes through the inside of the wick guide tube 2 and enters the air hole 11 of the inner flame tube 6.
Then, the air is supplied into the combustion chamber s from the lower part of the combustion tube through the air hole 11 of the outer flame tube 7, diffuses and mixes with the vaporized fuel gas, and rises in the combustion chamber 8 while being combusted. In the vicinity of the red-hot part 16 of the outer flame cylinder 7, high-temperature combustion gas containing unburned components rises close to the inner surface of the red-hot part 16 and heats the red-hot part 16 to red-hot. The radiant heat generated from this red-hot surface is used for heating.

らに灯芯１の近傍の小孔１１より供給される空気によっ
て灯芯１の気化面近傍の燃料ガス分圧を低下させること
により所定の気化量を得ることができる。In order to obtain a large amount of combustion, the exposed height of the lamp wick 1 into the combustion chamber 8 is increased, and the lamp wick 1 receives radiant heat from the flame in the combustion chamber 8, the heated inner flame tube 6, the lower part of the outer flame tube 7, The lamp wick 1 is heated by conductive heat from the wick guide tube 2 and the wick outer tube 3, which are in contact with the sides thereof, and the fuel impregnated inside is also heated. Furthermore, a predetermined amount of vaporization can be obtained by lowering the partial pressure of the fuel gas near the vaporizing surface of the lamp wick 1 using air supplied from the small hole 11 near the lamp wick 1.
燃焼量を少なくするために灯芯１の露出高さを低くする
と内炎筒６、外炎筒７の小孔から供給される空気が灯芯
の表面に触れなくなり、気化量が低減する。In order to reduce the amount of combustion, if the exposed height of the wick 1 is lowered, the air supplied from the small holes of the inner flame tube 6 and the outer flame tube 7 will not come into contact with the surface of the wick, and the amount of vaporization will be reduced.
この種の燃焼方式の特徴として灯芯の露出高さを低くし
て気化量を調節すると一時的に気化量が大幅に低下する
がしばらくすると露出高さを低くした直後に比べ増加す
る現象がある。これは供給される空気量に対して気化量
か減少するために燃焼室下部での燃焼量が増加し灯芯お
よび灯芯近傍への熱量の供給が増えることによって灯芯
からの気化量が増加することが主な原因である。A characteristic of this type of combustion method is that when the exposed height of the wick is lowered to adjust the amount of vaporization, the amount of vaporized temporarily decreases significantly, but after a while, it increases compared to immediately after lowering the exposed height. This is because the amount of vaporization decreases relative to the amount of air supplied, so the amount of combustion at the bottom of the combustion chamber increases, and the amount of heat supplied to the wick and the vicinity of the wick increases, causing an increase in the amount of vaporization from the wick. This is the main cause.
また灯芯の露出高さを低くすると灯芯の温度が上昇する
ことにより小燃焼量の状態から露出高さを高くして燃焼
量を増やすと一時的に気化量が過大となり燃焼室内で燃
焼が完了しないために燃焼筒の出口に過大の火炎を形成
する現象ある。これは灯芯の露出高さの低い小燃焼量時
において灯芯および灯芯近傍の温度が高く、燃焼量を増
加するために露出高さを高くすると一時的に温度の高い
状態で灯芯の気化面積が増加するために気化量が過大に
なるためであり温度が低下すると通常の気化量の復帰す
る。Also, if the exposed height of the wick is lowered, the temperature of the wick will rise, so if you raise the exposed height to increase the combustion amount from a small combustion amount state, the amount of vaporization will temporarily become excessive and combustion will not be completed in the combustion chamber. Therefore, there is a phenomenon in which an excessive flame is formed at the exit of the combustion tube. This is because the temperature of the wick and the vicinity of the wick is high when the exposed height of the wick is low and the amount of combustion is small, and when the exposed height is increased to increase the amount of combustion, the vaporization area of the wick increases in a temporarily high temperature state. This is because the amount of vaporization becomes excessive because of this, and when the temperature decreases, the amount of vaporization returns to the normal amount.
本発明の構成によれば燃焼室８の下部での燃焼量が増加
しても芯案内筒２の内部に設けた整流具２１により空気
が芯案内筒２の内壁面に沿って流れるために内火皿４お
よび芯案内筒２の上部が冷却され芯案内筒２から灯芯１
への伝導熱が少ない。According to the structure of the present invention, even if the amount of combustion in the lower part of the combustion chamber 8 increases, the flow straightener 21 provided inside the core guide tube 2 allows the air to flow along the inner wall surface of the core guide tube 2. The upper parts of the fire pan 4 and the wick guide tube 2 are cooled, and the lamp wick 1 is removed from the wick guide tube 2.
There is little conduction heat to.
したがって燃料は灯芯１の露出面からは気化するが火皿
面より下の非露出からの気化量が少なくなる。Therefore, fuel is vaporized from the exposed surface of the lamp wick 1, but the amount of fuel vaporized from the non-exposed portion below the fire pan surface is reduced.
従来、灯芯１の露出高さを低くした場合には燃焼位置の

案内筒２が熱伝導によって加熱され、さらに芯案内筒２
に接した灯芯１が加熱されるために、非露出部である灯
芯１の側面からの気化量が多く火皿２．３より上の露出
高さを低くしても総気化量が低下し難いと言う問題があ
ったが本発明の構成によって非露出部からの気化量が低
減したために総気化量が低下し易くなった。その結果の
一例を図に示すが第４図は灯芯の露出高さに対する燃焼
量の変化を、第５図は灯芯の露出高さに対する内火皿の
温度の変化を示す。Conventionally, when the exposed height of the lamp wick 1 is lowered, the temperature of the inner fire pan 4 increases due to the lowering of the combustion position, and the wick guide tube 2 located below is heated by heat conduction.
Since the wick 1 in contact with the wick 1 is heated, there is a large amount of evaporation from the side of the wick 1, which is the non-exposed part, and even if the exposure height above the fire pan 2.3 is lowered, the total amount of evaporation is difficult to reduce. However, since the structure of the present invention reduces the amount of vaporization from the non-exposed portion, the total amount of vaporization tends to decrease. An example of the results is shown in the figures. FIG. 4 shows the change in combustion amount with respect to the exposed height of the wick, and FIG. 5 shows the change in the temperature of the inner fire pan with respect to the exposed height of the wick.
したがって燃焼量を少なくするために必要以上に灯芯の
露出高さを低くすることがなく、灯芯や火皿部へのター
ルの生成が少なく、また間部の温度上昇が少ないために
灯芯を降下して消火する時にも短時間に消火する。Therefore, in order to reduce the amount of combustion, the exposed height of the wick is not lowered more than necessary, there is less tar generated on the wick and the fire pan, and the temperature rise in the area is small, so the wick can be lowered. Even when extinguishing a fire, it extinguishes it in a short time.
また小燃焼量時に灯芯１および火ｆ［ｌＩ４．５の温度
上昇が少ないために露出高さを高くした時も気化量が過
大になる程度も大幅に低減できる。Furthermore, since the temperature rise of the lamp wick 1 and the flame f[lI4.5 is small when the combustion amount is small, the extent to which the amount of vaporization becomes excessive can be significantly reduced even when the exposure height is increased.
