In the above structure, at the start of combustion, the air supplied from the blower is heated by the electric heater in the air heating chamber to become warm air and is supplied to the vaporization chamber. On the other hand, the fuel is supplied to the fuel nozzle by the fuel pump and jetted in a mist state from the tip of the fuel nozzle facing the vaporization chamber into the vaporization chamber, diffused into the warm air and vaporized by the heat. The vaporized gas mixes with warm air and starts burning in the burner. During the combustion, the air supplied from the blower is heated by the combustion heat when passing through the heat exchanger provided above the burner, becomes warm air, and is supplied to the vaporization chamber to vaporize the fuel. Therefore, at the time of combustion, most of the heat source for heating the air into warm air is supplied by the combustion heat, so that the power can be reduced. Further, in the process of vaporizing the fuel in the vaporization chamber, the fuel is diffused by the hot air and vaporized, so that tar is not generated on the inner wall surface of the vaporization chamber.

The operation of the above configuration will be described. That is, when the blower 8 is operated and the electric heater 15 is energized, the air passing through the heat exchanger 17 and the air heating chamber 14 is heated to become warm air, and the vaporization chamber 11 passes through the air chamber 12.
Is supplied to. When the warm air temperature reaches a predetermined temperature, this is detected by the temperature detector 26 provided in the air conduit 16, and the fuel pump 20 operates. The fuel in the fuel tank 21 is atomized by the fuel pump 20 from the ejection port of the fuel nozzle 19 and ejected into the vaporization chamber 11. On the other hand, the warm air generates a swirling flow along the inner wall of the vaporization chamber 11 because the air port 13 serving as a passage has the cut-and-raised pieces 13a in the process of being supplied from the air chamber 12 into the vaporization chamber 11. Fuel nozzle 1
The mist-like fuel ejected from 9 is heated by the swirling flow of the warm air, becomes vaporized gas, mixes with the warm air, and passes through the supply pipe 22 and is ejected from the flame opening provided at the upper part of the burner 23 to the igniter Ignition (not shown) initiates combustion. When the combustion is started, the air supplied from the blower 18 is heated by the heat of combustion in the heat exchanger 17 provided above the burner 23 to become warm air and is supplied to the vaporization chamber 11 via the air heating chamber 14. To be done. At this time, when the temperature of the warm air supplied to the vaporization chamber 11 exceeds a certain temperature, the temperature detector 26 detects the temperature and reduces the power supplied to the heater 15 so that the temperature of the hot air is controlled to be constant. It
