本発明は着火スイツチに連動して、着火時のみ
着火ヒータ部に集中的に混合ガスを供給すること
により、着火を確実にするようにした触媒燃焼装

必要であり、着火方法として次のものが従来より
用いられていた。 Gas fuels that are gaseous at room temperature such as methane, ethane, propane, butane, naphtha, benzine, etc.
It has been known for a long time that a fuel that is liquid at room temperature, such as alcohol, is vaporized and burned on the surface of a catalyst to provide a heat source. This catalytic combustion requires that the temperature of the catalyst rise above the temperature at which an oxidation reaction can occur at the time of ignition, and the following ignition methods have been conventionally used.

多いため、加熱が不充分となり、着火はさらにし
にくくなる。 The present invention relates to an improvement of the above-mentioned ignition method. In conventional catalytic combustion devices, the mixed gas is supplied uniformly to the entire catalyst using a diffuser plate, etc., so there is less fuel supplied to the catalyst part that is in contact with the ignition heater, and therefore the amount of heat generated is small. However, it had the disadvantage of being difficult to ignite. In cordless catalytic combustion equipment, batteries are often used as the power source for the ignition heater, which results in insufficient heating and makes ignition even more difficult.
本発明は上記従来の欠点を解消したものであ

That is, in the present invention, the mixed gas is supplied in a concentrated manner to the catalyst portion in contact with the ignition heater in conjunction with the operation of the ignition switch only at the time of ignition.

７の連係ロツドである。 Examples thereof will be described below with reference to the accompanying drawings. In the figure, 1 is a combustion tube/case, and a catalyst 2 is provided inside thereof. Reference numeral 3 denotes an ignition heater, which is installed in close contact with the ignition part 2' of the catalyst 2, and is connected so that when the ignition switch 4 is operated, a current flows through it and heats it. 5 is a nozzle for injecting a mixed gas of fuel gas and air, and 6 is a diffusion plate provided so that the mixed gas is uniformly supplied to the entire catalyst 2. Reference numeral 7 designates a pair of movable blades for centrally supplying the mixed gas flow to the ignition heater 3, the tips of which face the catalyst 2, and are normally biased by a spring 8 in a direction parallel to the combustion cylinder 1. There is. The other end of the movable blade 7 is connected to an operating rod 10 of the ignition switch 4 by an operating rod 9. 11 is a button for operating the ignition switch 4; 12 and 13 are fulcrum shafts of the movable blades 7 and the operating rod 9; and 14 is a linking rod for the pair of movable blades 7.

燃焼する。 In the above configuration, when the button 11 of the ignition switch 4 is operated to the ignition position, a current flows through the ignition heater 3, and the ignition portion 2' of the catalyst 2, which is in close contact with the ignition heater 3, is heated. At the same time, a mixed gas of fuel gas and air is injected from the nozzle 5. Furthermore, at this time, the operating rod 10 moves in the A direction, and the tip of the movable blade 7 is displaced in the B direction via the operating rod 9. As a result, the distance between the tips of the pair of movable blades 7 is narrowed, and the mixed gas injected from the nozzle 5 is concentratedly supplied to the ignition section 2' of the catalyst 2 that has come into contact with the ignition heater 3. Therefore, a large amount of fuel is partially supplied to start combustion, and the amount of heat generated per unit area of the catalyst 2 increases, causing a temperature rise in the ignition part 2' of the catalyst 2 that has come into contact with the ignition heater 3. Since the ignition becomes quick, ignition becomes easy and reliable. When ignition is completed, the button 11 of the ignition switch 4 is set to the steady combustion position, and the pair of movable blades 7
It is displaced to a position parallel to the combustion tube 1, from which the mixed gas is uniformly supplied to the entire surface of the catalyst 2, and the entire surface is combusted.

事が出来る。 As described above, according to the present invention, the movable blade is displaced in conjunction with the operation of the ignition heater, and the mixed gas is intensively supplied to the ignition part of the catalyst that is in contact with the ignition heater only at the time of ignition, thereby ensuring ignition. It is possible to obtain a catalytic combustion device with good ignition performance.
