PURPOSE:To prevent the deterioration of a ceramic heater by a method wherein a combustion air blower is separately provided on the lower side of a ventilating cylinder so that the generation of a fire hazard is prevented and the burner produces a high temperature flame. CONSTITUTION:Oil supplied by an oil supply device 23 scatters by dropping down on a conical section and when the scattering oil reaches the inner surface of a heating cup 19, it is flung away due to a centrifugal force. In this case, air blown out by the blower 29 passes through an inclined opening 27 an elastic ventilating pipe throughholes 16 an opening 18 at the top end of the burner a gap 21 so that the oil is gasified and mixed completely with air in a gasification chamber 35 so as to be injected into a combustion chamber 36 located outside a combustion plate 33. Therefore, if the ceramic heater 34 is energized, the mixed gas is ignited and burned. Accordingly, the outer surface of the heating cup 19 is heated red and the oil in th gap 21 is gasified actively to produce a blue flame. Further, as cool dry air is blown toward the ceramic heater 34 through a ventilating port 39 to cool the heater, the heater is prevented from deteriorating in a short time. |
