KR970028086A - Instantaneous ignition device for gas burner - Google Patents

Abstract

The present invention relates to an instantaneous ignition device for a gas combustor, and more particularly, to an instantaneous ignition device for a gas combustor in which the ease of use and safety are maximized by controlling a spark discharge by an ignition device and a thermocouple output for opening and closing a safety valve. The thermocouple which operates simultaneously with the start of ignition at the beginning of ignition and supplies the power voltage to the MPU so that the MPU can be opened regardless of the thermocouple (TC), and generates the thermoelectric power for driving the MPU. The opening and closing level of the MPU can be set to a high opening and closing level, and the opening and closing level is increased, so the gas shut off during abnormal extinguishing increases safety, and the MPU can be relatively high precision processing, which is easy to process and economical. To provide gas igniter ignition devices, switches and switches for gas switching and spark discharge from the power source A power supply for generating a delayed output for a certain time by the power switch to a normal ignition device composed of an ignition circuit operated by the power supply and connecting the power supply to the MPU during this delayed output time, and cutting off the power supply after this delay time ends. MPU is driven by the delay output is made of the switching means, characterized in that the MPU is driven by the thermocouple when the delay output is terminated.
