Embodiment Construction

[0032] Next, forms for carrying out the present invention will be described. figure 1 The configuration of the discharge ignition device for a burner according to the first embodiment of the present invention is shown. The discharge ignition device 1 for a burner shown in this figure has a high voltage generator 2 and a spark plug 3 . Such a discharge ignition device 1 for a burner is used for various burners such as a gas burner such as a gas stove or a water heater, and a kerosene burner such as a kerosene fan heater.

[0033] The high voltage generator 2 has an external case 11 made of an insulating material such as resin. An ignition transformer 12 and a circuit unit 15 in which electronic components 13 such as diodes and resistors are mounted on a printed circuit board 14 are housed in the external case 11 . The ignition transformer (step-up transformer) 12 has a bobbin 16 around which a secondary coil is wound on the outer peripheral side. A magnetic core 17 such as a...

Abstract

A high-voltage generator 2 has the ignition transformer 12 for stepping up an electric power source voltage to a prescribed high voltage. An electric power source terminal 22 connected to a primary coil of the transformer 12 and a grounding terminal 23 connected to a secondary coil are arranged on the same plane 21 of an outer casing 11. The power source terminal 22 and the grounding terminal 23 are installed, for example, as a three-terminal type connector 24 in the outer casing 11. An output terminal 26 connected to the secondary coil of the transformer 12 is connected electrically to a discharge terminal 31 of the ingition transformer 12. The discharge ignitor 1 is constituted of the high-voltage generator 2 and an ignition plug 3.

Description

technical field [0001] The invention relates to a discharge ignition device used in various burning appliances such as gas burning appliances or kerosene burning appliances. Background technique [0002] In various combustion appliances such as gas furnaces and water heaters, a discharge igniter is used as an ignition source. As a discharge ignition device for a burner, a combination of a high-voltage generator having an ignition transformer for raising a power supply voltage to a predetermined high voltage and a spark plug provided near a gas burner or the like is generally used. In such a discharge ignition device, a spark is generated from a discharge electrode of a spark plug by a secondary side voltage boosted by an ignition transformer, thereby igniting a gas burner or the like. [0003] As an ignition transformer of a high-voltage generator, for example, a transformer having a structure in which a magnetic core around which a primary coil is wound is inserted through...
