Abstract

본 발명은 가스보일러에 관한 것으로서, 더욱 구체적으로는 가스보일러의 버너에 공급되는 연료를 점화시키기 위하여 고전압에 의한 방전을 수행하는 아그나이터의 외부방전 및 고장감지방법에 관한 것이다. 전체 행정을 제어하기 위한 마이컴(19)와, 상기 마이컴(19)의 제어신호에 따라서 고압방전을 발생하는 이그나이터(7)와, 버너에서의 착화상태를 감지하기 위한 불꽃 감지부(9)와, 배기팬(15)과, 이그나이터(7)의 방전상태를 확인하기 의한 적외선센서(21)를 포함하는 가스보일러에 있어서, 보일러 작동명령이 입력된 후에 마이컴(19)으로부터 제어신호가 출력되어 버너에서의 착화에 필요한 고전압방전이 이그나이터(7)에서 수행되면, 버너에 케이스(25) 표면에 설치된 적오선 센서(21)를 사용하여 이그나이터(7) 첨두부(7a)에서의 방전을 감지하여, 방전이 감지되면 연소행정을 수행하고, 방전이 감지되지 않으면 표기부(23)를 사용하여 외부에 불량을 표시하는 것을 특지응로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas boiler, and more particularly, to an external discharge and failure detection method of an agniter which discharges by a high voltage to ignite a fuel supplied to a burner of a gas boiler. A microcomputer 19 for controlling the entire stroke, an igniter 7 for generating a high voltage discharge according to the control signal of the microcomputer 19, a flame detector 9 for detecting the ignition state of the burner, In the gas boiler including the exhaust fan 15 and the infrared sensor 21 for checking the discharge state of the igniter 7, a control signal is output from the microcomputer 19 after the boiler operation command is input and the burner When the high voltage discharge required for the ignition of the igniter 7 is performed in the igniter 7, the discharge is sensed by detecting the discharge at the tip 7a of the igniter 7 by using the erode sensor 21 installed on the case 25 at the burner. If this is detected, the combustion stroke is performed, and if the discharge is not detected, the display unit 23 is used to display a defect on the outside.

Claims

A microcomputer 19 for controlling the entire stroke, an igniter 7 for generating a high voltage discharge according to the control signal of the microcomputer 19, a flame detector 9 for detecting the ignition state of the burner, In the gas boiler including the infrared sensor 21 for confirming the discharge state of the igniter 7, the high voltage discharge which requires the ignition in the burner by outputting a control signal from the microcomputer 19 after the borer operation command is input. When performed in the igniter 7, the burner detects discharge at the tip 7a of the igniter 7 by using an infrared sensor 21 installed on the surface of the case 25 in the burner, and performs a combustion stroke when the discharge is detected. And, if the discharge is not detected, the external discharge and failure detection method of the igniter, characterized in that by using the display unit 23 to display a defect.

The method of claim 1, wherein the reference value indicating the discharge degree is set, and when the intensity is less than the reference value, the reference value is recognized as an external discharge, and when the reference value is higher than the reference value, the discharge is recognized as a normal discharge.
