Abstract
An igniter for a burner in a cooking system. The igniter comprises a spark unit including two electrodes that define a spark gap, a spark module electrically connected to the electrodes to apply a high-voltage pulse across the electrodes to generate a spark in the spark gap, and a remote sending unit that sends an ignite signal to the spark module to generate a spark in the spark gap to light the burner. A local ignite signal can be initiated from the spark module. The spark module and the remote sending unit can be clamped to a gas hose supplying gas to the burner. The spark unit can be attached to a variety of burners by attachments to position the spark gap in the burner's gas flow. A single-electrode igniter is also described.
Claims31
An igniter comprising:
- a spark module;
- a spark unit including at least one electrode having a distal end, wherein the at least one electrode is electrically connected to the spark module;
- a sending unit remote from the spark module and having an actuator, that when actuated, causes the sending unit to send an ignite signal to the spark module to send a high-voltage pulse to the at least one electrode to generate a spark at the distal end.
An igniter comprising:
- a spark unit including at least one electrode having a distal end;
- a spark module including:
- a high-voltage pulse generator connected to the at least one electrode;
- a fastener suitable for attaching the spark module to a gas hose;
- a sending unit including an actuator that, when actuated, causes the sending unit to send an ignite signal to the high-voltage pulse generator to send a high-voltage pulse to the at least one electrode to generate a spark at the distal end.
A spark unit comprising:
- a first ceramic insulator and a second ceramic insulator, each having a first end and a second end;
- a first electrode extending from the second end of the first ceramic insulator to a distal end;
- a second electrode extending from the second end of the second ceramic insulator to a distal end;
- a bridge extending from the first ceramic insulator to the second ceramic insulator between the first and second ends to fix the spacing between the first and second ceramic insulators;
- wherein the bridge has a top that angles downward and outward to allow fluids to drain off;
- wherein the distal ends of the first and second electrodes converge toward each other to form a spark gap between the distal ends.
A cooking system comprising:
- a burner having a gas outlet;
- a gas hose carrying gas to the burner;
- an igniter including:
- a spark unit attached to the burner and including at least one electrode having a distal end at the gas outlet of the burner;
- a spark module including:
- a high-voltage pulse generator electrically connected to the at least one electrode and sending a high-voltage pulse to the at least one electrode to generate a spark that ignites the gas flowing through the outlet;
- a fastener attaching the spark module to the gas hose.
