Abstract
A gas oven comprises at least a first burner element disposed within an oven cavity of the gas oven. A first control valve is disposed within a gas line connected to the burner element and to a gas source. The control valve controls gas flow to the burner element. A first temperature sensor is positioned so as to detect temperature about the burner element. A controller is electrically coupled to the temperature sensor and to the control valve wherein the controller ensures successful ignition of the burner element by monitoring the temperature signals generated from the temperature sensor to determine if the temperature signals increase a rate that is greater than a predetermined.

A gas oven comprising:
- at least one burner element disposed within an oven cavity of said gas oven;
- at least one control valve disposed within a gas line, said gas line connected to said burner element and to a gas source, wherein said control valve controls gas flow to said burner element;
- at least one temperature sensor positioned so as to detect temperature about said first burner element;
- and
- an ignitor disposed adjacent said at least one burner element;
- a controller electrically coupled to said ignitor, said at least one temperature sensor and to said at least one control valve wherein said controller ensures successful ignition of said at least one burner element by monitoring the temperature signals generated from said at least one temperature sensor to detect if said temperature signals increase at a rate that is greater than a predetermined ignition rate;
- wherein if consecutively monitored temperature signals generated by said temperature sensor do not increase at a rate that is greater than a predetermined ignition rate, said controller generates a control signal to close said respective control valve;
- and wherein said controller generates a control signal to maintain said at least one control valve in a closed position during a purge stage so as to purge said oven cavity of unburned fuel therein.
A gas oven comprising:
- a first burner element and a second burner element disposed within an oven cavity of said gas oven;
- a first control valve disposed within a first gas line, said first gas line connected to said first burner element and to a gas source, wherein said first control valve controls gas flow through said first burner element;
- a second control valve disposed within a second gas line, said gas line connected to said second burner element and to said gas source, wherein said second control valve controls gas through said second burner element;
- a first temperature sensor and a second temperature sensor positioned so as to detect temperature about said first and second burner elements, respectively;
- and
- a controller electrically coupled to said first and second control valves, and to said first and second temperature sensors wherein said controller ensures successful ignition of said first and second burner elements respectively by monitoring the temperature signals generated from said first and second temperature sensors respectively to detect if the temperature signals increase at a rate that is greater than a predetermined ignition rate;
- wherein if consecutively monitored temperature signals generated by said temperature sensor do not increase at a rate that is greater than a predetermined ignition rate, said controller generates a control signal to close said respective control valve;
- and wherein said controller generates a control signal to maintain said at least one control valve in a closed position during a purge stage so as to purge said oven cavity of unburned fuel therein.
