Abstract

PURPOSE:To enhance certainty of ignition by operating an igniter before vaporized gas for starting combustion is generated. CONSTITUTION:Before a fuel supply unit having a solenoid pump 2 and a solenoid 4 is controlled to generate vaporized gas, igniter 5 is operated, and a warm air fan 6 is started to be operated after a short time. Whether a combustion flame is detected or not is decided through a flame detector 7, and when the presence of flame is decided, the igniter 5 is stopped while the operations of an evaporator heater 3, a warm air fan 6 and the unit are continued, and an operation for heating is transferred. Thus, certainty of ignition is enhanced, and generation of white smoke due to failure of the ignition can be suppressed.

However, in the case of this conventional example, at the same time as the ignition command (completion of ignition preparation), the solenoid 4 is operated to open the vaporized gas ejection port of the carburetor and start the operation of the electromagnetic pump 2. Therefore, the concentration of the vaporized gas to be ejected is low at the beginning and then gradually increases, so that it may not be instantly ignited, and ignition may be performed while emitting white smoke in the room. In addition, in the case where it is determined that there is no flame due to an erroneous ignition, white smoke continues to be emitted indoors while the electromagnetic pump 2 is operating.
