The temperature control device 19 controls the supply of the mixed gas to the catalytic combustion portion 20. Control the combustion temperature. The electronic device 8 is configured to be heated via the heat transfer plate 11 by the heat generated in the catalytic combustion unit 20.

The catalyst 21 is carried on a corrugated carrier, and is disposed on the inner surface of a cylindrical case 22 made of a material having good heat conductivity such as aluminum or copper. An exhaust port 23 is provided on a side wall of the case 22. An electric insulator 24 made of ceramic or the like is provided on the inner surface of the case 22 on the downstream side of the catalyst 21, and a discharge electrode 25 which ignites the catalyst 21 by emitting a spark when the electric insulator 24 ignites.
Are provided to constitute the catalytic combustion unit 20.

The temperature control device 19 is configured as shown in FIG. 6. The temperature-sensitive ferrite (temperature-sensitive magnetic material) 26 has a Curie point (for example, 120 ° C.) at which the magnetic characteristics change rapidly.
C), is formed in a ring shape, and is fixed to the outer shell 27. The magnet 28 is provided to face the temperature-sensitive ferrite 26,
The temperature-sensitive ferrite 26 is sucked, the valve member 29 is held on the surface opposite to the temperature-sensitive ferrite 26, and the outer shell 2
A valve holder 31 having a predetermined gap 30 is fixed to the inner surface of the valve 7. The spring 32 urges the magnet 28 in a direction away from the temperature-sensitive ferrite 26.

The valve body 33 is provided with a valve port 34 facing the valve member 29 to form a valve, and has a nozzle 35 for ejecting vaporized fuel gas toward the catalyst 21 at a position opposite to the valve port 34. Provided. Here, the direction in which the fuel gas flows and the direction in which the valve closes are set to the same direction. The outer shell 27 is press-fitted and fixed to the inner surface of one end of the case 22. Numeral 36 denotes a fuel gas supply port. As shown in FIG. 3, a fuel tank 13 containing combustion gas and a gas flow control mechanism 15 are provided.
Connected through.

A hole for taking in air, that is, a so-called intake port 37 is provided between the catalyst 21 and the nozzle 35. At this time, the air inlet 37 faces the protective cover 17 and faces the outer surface of the storage case 7.

In the above configuration, first, the operation of the catalytic combustion heating device 10 will be described. When the fuel gas is supplied from the fuel tank 13 through the fuel gas supply port 36, the fuel gas passes through the central portion of the temperature-sensitive ferrite 26, passes through the gap 30 between the temperature-sensitive ferrite 26, the magnet 28, and the valve holder 31, It reaches port 34 and blows out from nozzle 35.
At this time, air is drawn in from the intake hole 37 by the flow rate of the fuel gas, and becomes a mixture of the fuel gas and the air, and is supplied to the catalyst 21.

Then, the ignition button 18 arranged outside the storage case 7 is operated to operate the continuous discharge ignition device (not shown), and the spark is continuously discharged from the discharge electrode 25, whereby the catalyst 21 is discharged. A flame is reliably generated on the discharge electrode 25 side. The shape of the catalyst 21 is a shape suitable for producing a flame. The generated flame heats the catalyst 21 and starts a catalytic reaction. When the catalyst 21 starts the catalytic reaction, only the exhaust gas comes to the flame, and the flame naturally disappears. The case 22 is heated by the catalytic reaction, and the heat transfer plate 11 is heated by the catalytic combustion heat.

The case 22 of the catalytic combustion section 20 is heated, and the outer shell 27 is heated by the heat, so that the temperature-sensitive ferrite 26 fixed to the outer shell 27 is heated. When the temperature reaches the Curie point determined by the composition, the magnet 28 cannot absorb the temperature-sensitive ferrite 26, is separated from the temperature-sensitive ferrite 26 by the spring 32, and the valve member 29 moves toward the valve body 33 to close the valve port 34. . As a result, the fuel gas is no longer supplied to the catalyst 21, and the temperature decreases.

The temperature-sensitive ferrite 26 has a very small hysteresis and returns to its original state with a temperature change of several degrees or less.
When the temperature-sensitive ferrite 26 returns, the magnet 28 again attracts the temperature-sensitive ferrite 26 and opens the valve port 34. During this time, the temperature of the catalyst 21 is sufficiently high because the time is short, and when the fuel gas is supplied, the catalytic reaction starts again. By repeating this operation, the temperature of the case 22 can be kept constant.

The control temperature at this time is the temperature-sensitive ferrite 2
6, the temperature controller 19 made of the temperature-sensitive ferrite 26 having the same composition can control the temperature at the same temperature, and does not require adjustment at the time of assembly. For this reason, mass production becomes very easy. Further, when the set temperature is to be changed, the temperature-sensitive ferrite 26 having a predetermined composition may be combined, which can be performed very easily.
