PURPOSE: To contrive to make the amount of the combustion and air-fuel ratio constant by a method wherein an evaporator, accommodating a sucking body and an heating body and communicating with a fan and a combustion unit, fuel liquid temperature and air temperature in the evaporator, and the control unit of the amount of conducted electric current of the heating body are provided in the title device.
CONSTITUTION: Almost all of the amount of heat generated by the conduction of a heating body 5 becomes sensible heat and latent heat evaporating the oil of a sucking body 6 and contributes to evaporate the oil. In this case, the oil temperature may move up and down by the fluctuation of atmospheric temperature, the effect of heat of combustion, oil supplying operation or the like. The detecting unit 9 of oil temperature is provided in order to correct above factor and the amount of conducted electric current of the heating body 5 is reduced in accordance with the increase of the oil temperature to make the amount of combustion constant. The detecting unit 10 of atmospheric temperature is provided on the way of an air path and the air-fuel ratio is controlled so as to make it constant by changing the amount of conducted electric current in accordance with the fluctuation of the atmospheric temperature.
