BURNER
First Claim
1. A burner comprising a burner head having burner ports, an intake pipe through which a mixture of gas and air is configured to be supplied to the burner head so as to be released through the burner ports, a core wire provided adjacent to the burner ports, and an electric discharge generator arranged to generate electric discharge from the core wire, thereby igniting the mixture,wherein the burner further comprises an electric wire extending through the intake pipe and connecting the core wire to said means electric discharge generator, said burner head being formed with a through hole through which the core wire extends from inside to outside the burner head, and wherein an insulator is disposed between the core wire and the burner head to keep the core wire insulated from the burner head.

Abstract
The object is to prevent damage to and overheating of an electric wire for electric discharge/ignition of a burner, thereby increasing its life, without increase in cost.
The burner includes a housing 1, an intake pipe 3 and a burner head 4. Gas in the housing 1 is supplied to the burner head 4 through the intake pipe 3. An electric wire 8 extends through the intake pipe 3 which connects a piezoelectric element 7 to a core wire 10 from which electric discharge is generated near burner ports 9 of the burner head 4 by the piezoelectric element 7. Since the wire 8 is not exposed to outside the intake pipe 3, the wire 8 is never caught and damaged by an external object. Since air-gas mixture which is kept at around the room temperature is flowing through the intake pipe 3, the wire 8 is less likely overheat during use of the burner. Thus, it is not necessary to provide the wire 8 with a shield plate for protecting the wire 8. This simplifies the manufacturing steps and thus reduces the manufacturing cost.
