<p>PURPOSE:To obtain a combustion apparatus reduced in electromagnetic noise by mounting a high voltage generator performing discharge, a high voltage generator generating high voltage and a high voltage generator control apparatus. CONSTITUTION:When an operating switch is closed, a relay contact 13 is closed to supply a current to a preheater 9. When preheating is completed, a relay contact 14 is closed to supply a current to an electromagnetic pump 4 and a motor 5 and air necessary for combustion is sent under pressure. Next, a relay contact 19 is closed to rotate a hot air blowing motor and a relay contact 16 is closed to supply a current to the first high voltage generator and spark discharge is performed to form a flame. When the flame is formed, a sensor means 10 detects said flame to output a detection signal to a microcomputer 1. The microcomputer 1 inputs said signal to open a relay contact 10 and the discharge of a spark is stopped. By this method, electromagnetic noise is reduced.</p> |
