Abstract

본 발명은 무소음 고압방전 점화장치에 관한 것으로 특히, 스타트 스위치(1)의 구동으로 인해 고압트랜스(4)에서 고전압이 방전되어 점화플러그(6)에서 불꽃이 발생되면 공급되는 연료가 점화되는 구성의 연소기기 점화 장치에 있어서, 상기 스타트 스위치(1)가 "온"되면 소정프로그램에 의해 가청주파수 이상의 주파수를 갖는 소정의 출력신호를 발생시키는 마이컴(3)과; 상기 마이컴(3)에서 출력되는 구동신호의 주기에 맞추어 온/오프되어 고압트랜스(4)의 2차측에서 이 주기에 대응되는 주파수를 갖는 고전압이 출력되도록 하는 에미터 접지형 트랜지스터(5)를 개재하여 주므로써, 방전소음을 완전 차단시킬 수 있을 뿐만 아니라 회로구성이 간단하여 제품의 생산원가를 대폭 절감시킬 수 있는 것이다.The present invention relates to a noiseless high-pressure discharge ignition device, in particular, a high voltage is discharged in the high-voltage transformer (4) due to the drive of the start switch (1) of the configuration that the fuel supplied when the spark is generated in the spark plug (6) is ignited A combustion device ignition device comprising: a microcomputer (3) for generating a predetermined output signal having a frequency higher than or equal to an audible frequency by a predetermined program when the start switch (1) is turned "on"; Interposed between the emitter ground type transistor 5 to turn on / off in accordance with the period of the drive signal output from the microcomputer 3 so that a high voltage having a frequency corresponding to this period is output from the secondary side of the high voltage transformer 4. By not only completely discharging the discharge noise, but also the circuit configuration is simple, which can greatly reduce the production cost of the product.
