Abstract:
A stove with a spark ignition system comprising:a stove body having a control panel; a gas burner mounted on said stove body; a gas valve mounted in said stove body and having an inlet coupled to a gas supply and an outlet coupled to said gas burner, said gas valve having a rotatable operating shaft extending from a rear side of said control panel to a front side thereof through a corresponding opening formed in said control panel; a knob having an upper side adapted for manual rotation thereof and a bottom side coupled to said operating shaft for rotating said operating shaft in correspondence with manual rotation of said knob, said knob having a magnet mounted adjacent a peripheral portion of said bottom side thereof; a magnetically operated switch mounted to said rear side of said control panel in proximity of said operating shaft, said magnetically operated switch having a pair of normally open contacts being closed responsive to said magnet being rotated to a predetermined angular extent by rotation of said knob, said knob rotation operating said gas valve to supply gas to said gas burner; a jump spark power source coupled to said contacts of said magnetically operated switch for generating a sparking voltage responsive to said closure of said contacts; and, a spark generator mounted adjacent said gas burner and electrically coupled to said jump spark power source by a lead wire for output of said sparking voltage to ignite the gas from the gas burner.
