It has long been known to mix with air and burn it on the surface of a catalyst to use it as a heat source. In this catalytic combustion, it is necessary that the temperature of the catalyst rises above the temperature at which the fuel can undergo an oxidation reaction on the surface of the catalyst, and the following ignition methods have been conventionally used.

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, a mixed gas of fuel gas and air is supplied uniformly to the entire catalyst using a diffuser plate, etc.
The amount of fuel supplied to the catalyst part that is in contact with the ignition heater is small, so the amount of heat generated in that part is also small, and even if fuel gas is flowed, it is difficult to ignite because the temperature rise in that part is small. It had the following drawback. Particularly in cordless combustors, 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

る。 That is, in the present invention, at the time of ignition (that is, when the catalyst is at a low temperature), a mixed gas of fuel gas and air is supplied in a concentrated manner to the catalyst part in contact with the ignition heater to obtain reliable ignition, and after ignition, A thermally responsive element is used to uniformly supply fuel gas to the catalyst.

In the figure, 1 is a combustion tube/case, and a catalyst 2 is provided inside thereof. Ignition heater 3 is catalyst 2
The ignition switch 4 is installed in close contact with the ignition switch 4, and is connected so that current flows and heats up when the ignition switch 4 is operated. 5 is a nozzle for injecting a mixed gas of fuel gas and air, and 6 is a diffusion plate for uniformly supplying the mixed gas to the entire catalyst 2. Reference numeral 7 designates a pair of movable blades for supplying a gas flow to the ignition heater 3 in a concentrated manner, and is normally biased via a spring 8 in a direction parallel to the combustion cylinder 1. This movable blade 7 is a thermally responsive element (bimetal in this figure) located at a position where the mixed gas is intensively supplied to the catalyst part 2' in contact with the ignition heater 3 as shown in Fig. 1 when the catalyst 2 is at a low temperature.
It is set by 9.

なる。 In the above configuration, when the button 10 of the ignition switch 4 is operated to the ignition position, a current flows through the ignition heater 3 and the catalyst portion 2' that 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. At this time, since the temperature of the catalyst 2 is low, the movable blades 7 are set in the state shown in FIG. Since a larger amount of fuel gas than the above is partially supplied, the calorific value per unit volume of the catalyst 2 increases, and the temperature of the catalyst part 2' in contact with the ignition heater 3 quickly rises, making ignition easy and , becomes certain.

着火特性を得る事が出来る。 When ignition is completed and the temperature of the catalyst 2 rises, the thermally responsive element 9 deforms in the direction A and becomes parallel to the combustion tube 1 as shown in FIG. 2 and is combusted throughout. The amount of displacement of this thermally responsive element 9 varies depending on the temperature of the catalyst 2. In other words, if the room temperature fluctuates, or if the catalyst temperature is still high after the fire has been extinguished, move the movable blade 7 to a position commensurate with the temperature.
is displaced. Therefore, since settings can be made so that an optimum mixed gas flow can be supplied to the catalyst 2, stable ignition characteristics can always be obtained.
なお、熱応動素子９は着火ヒータ３の熱を直接
感知しない位置に設置する事が必要である。 Note that it is necessary to install the thermally responsive element 9 in a position where it does not directly sense the heat of the ignition heater 3.
このように、本発明によれば、着火が確実であ
