なものとなる。 Normally, combustion starts as described above, but when the on/off switch 3 is on, the following happens. That is, when the on/off switch 3 is turned on, the central control circuit 4 detects this and operates the vaporizer heat-retaining means 5, and the heater control circuit 8 is activated based on a signal from the vaporizer heat-retaining means 5. At this time, the heater control circuit 8 operates to appropriately turn on and off electricity to the electric heater 9, or to continuously supply a predetermined small amount of electric power, so that the temperature of the vaporizer 7 is lower than a predetermined temperature. The temperature will be maintained at a low temperature. Then, when the operation switch 2 is turned on during the heat retention, the vaporizer heat retention means 7 is stopped, and ignition and combustion occur in the order described above. The heating time is significantly shortened and combustion occurs quickly, making the heater easier to use.
