本発明は液体燃料を毛細管現象によって吸上げ、気化室

関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called suction vaporization type combustion device that sucks up liquid fuel by capillary action and vaporizes and burns the liquid fuel from the surface of the vaporization part of the lamp wick exposed in the vaporization chamber. It is something.

積した場合等は点火困難となる。An example of this kind of combustion device is the porta-pull kerosene stove.As shown in Figure 1, the ignition device used in this type of combustion device uses a coil-shaped ignition heater 1 to become red-hot using the energy of a dry battery or the like, and ignites it. The heater 1 is brought close to a part of the vaporizing part 2 of the lamp wick and ignited. In this case, the ignition heater 1 is installed parallel to the side surface of the vaporization section 2. For ignition to occur, the temperature must be sufficiently high and the mixture ratio of vaporized fuel and air must be within the flammable range. That is, if the ignition heater 1 is brought too close to the vaporization section 2, the amount of fuel vaporized increases and the ratio with air exceeds the flammable range, resulting in only white smoke being generated and no ignition. Moreover, if the ignition heater 1 is too far from the vaporization section 2, the temperature will be too low and ignition will not occur. Therefore, the area where ignition is possible is limited to a certain range, but with conventional
As shown in the figure, since the side surface of the vaporization section 2 and the ignition heater 1 are set parallel, only a constant state can be obtained for the entire area of the width a of the ignition heater 1, and therefore the area where ignition can be ignited is very narrow. Subtle adjustments were required to set the position. Furthermore, in the wick type combustion device, the protrusion height of the vaporizing part 1 is not always ignited under constant conditions, and
If a tar-like substance accumulates at the tip of the vaporizer 1 after long-term use, it becomes difficult to ignite.
本発明は以上の様な従来の欠点を除去するもので、点火
ヒータによる点火可能範囲を広くとり常に容易に灯芯の
気化部に点火可能とすることを目的とする。The present invention is intended to eliminate the above-mentioned drawbacks of the conventional lamps, and aims to widen the ignition range of the ignition heater so that the vaporized portion of the wick can always be easily ignited.

易に点火が可能となる。In order to achieve this objective, the present invention has an ignition heater that is inclined horizontally and vertically (up and down) on the side of the vaporizing part of the lamp wick, and with this configuration, the ignition possible area can be set at any position of the ignition heater. Therefore, it is possible to always easily ignite a wide range of movable areas of the ignition heater.

。At the upper part of the core guide cylinder 3 and the core outer cylinder 4, there is an inner fire plate 5, respectively.
.. It forms an outer fire plate 6. 7 is a cylindrical inner flame tube, 8 is a cylindrical outer flame tube, and each has an inner flame pan 5. A large number of small holes 9 placed on the outer flame pan 6 are provided to introduce air into the combustion chamber 10 formed between the inner flame tube 7 and the outer flame tube 8. Reference numeral 11 denotes a cylindrical lamp wick that is attached vertically freely between the wick guide tube 3 and the core outer tube 4, and the portion exposed in the combustion chamber 1o above the wick 11 is a vaporizing section 12. Reference numeral 13 denotes a coil-shaped ignition heater for igniting the vaporizing portion 12, and the surface of the ignition heater 13 is treated with platinum to facilitate ignition. Reference numeral 14 denotes an ignition window through which the ignition heater 13 is introduced into the combustion chamber 1o during ignition. FIG. 4 shows the positional relationship between the vaporizer 12 and the ignition heater 13, with FIG. 4A being a plan view and FIG. 4A being a front view. As shown in FIGS. 4a and 4b, the ignition heater 13 has an inclination angle a with respect to the side surface of the vaporizing portion 1 and 2, and an inclination angle β with respect to the vertical direction. Therefore, the distance from the side surface of the vaporizer 12 is a difference between one end A and the other end B of the ignition heater 13, and there is a difference b in the vertical direction. Therefore, for example, the distance between the ignition heater 13 and the side surface of the vaporization section 12 is t.
If the optimum ignition state can be obtained when
However, by setting the distance difference a as in this embodiment, as long as the position of the ignition heater 13 is set within the range of xth-' from the side surface of the vaporizer 12, one end A of the ignition heater 3 Optimum conditions for ignition can be obtained at any position between and the other end B. Further, in a wick-type combustion device, although the exposed height of the vaporizing portion 12 at the time of ignition is set, the ignition is not always at the set position. Therefore, in this embodiment, a distance difference is provided in the vertical direction as well, and the optimum ignition condition can be obtained at any position between one end A and the other end B of the ignition heater B even with the difference in the vertical distance. .

ことができる。As described above, according to the present invention, since the ignition heater is inclined with respect to the horizontal and vertical directions of the side surface of the vaporizing part of the lamp wick, it is possible to obtain the optimum ignition condition at any position of the ignition heater. This eliminates the need to make fine adjustments to the ignition position settings due to the narrowing of the optimal ignition range, which was the case in the past, and allows the ignition position to be set over a wide range, making it easy to ignite at all times. You can make it happen.
