Abstract
A temperature setpoint is reestablished and maintained in a gas oven using multiple gas burners. In some instances, the multiple gas burners may be cycled using predetermined activation durations for each gas burner when reestablishing the temperature setpoint, and in some instances, the gas burners may be cycled over multiple iterations in order to reestablish the temperature setpoint. Furthermore, in some instances, each gas burner may include a spark igniter that may be used to minimize the amount of time required to ignite the gas burner when reestablishing the temperature setpoint.
Claims20
A cooking appliance, comprising:
- a housing including an oven cavity;
- a plurality of gas burners configured to generate heat within the oven cavity;
- a plurality of gas valves, each gas valve in fluid communication with a respective gas burner among the plurality of gas burners;
- a plurality of igniters, each igniter positioned proximate to a respective gas burner among the plurality of gas burners and configured to ignite gas supplied to the respective gas burner;
- and
- a controller coupled to the plurality of dedicated gas valves and the plurality of igniters, the controller configured to control the plurality of gas valves and the plurality of igniters to maintain a temperature setpoint during a cooking cycle, the controller further configured to reestablish the temperature setpoint during the cooking cycle by controlling the plurality of gas valves and the plurality of igniters to activate each of first and second gas burners among the plurality of gas burners over multiple iterations, and to deactivate the first gas burner between first and second activations of the first gas burner over the multiple iterations.

- a housing including an oven cavity;
- a plurality of gas burners configured to generate heat within the oven cavity;
- a plurality of gas valves, each gas valve in fluid communication with a respective gas burner among the plurality of gas burners;
- a plurality of igniters, each igniter positioned proximate to a respective gas burner among the plurality of gas burners and configured to ignite gas supplied to the respective gas burner;
- and
- a controller coupled to the plurality of dedicated gas valves and the plurality of igniters, the controller configured to control the plurality of gas valves and the plurality of igniters to maintain a temperature setpoint during a cooking cycle, the controller further configured to reestablish the temperature setpoint during the cooking cycle by controlling the plurality of gas valves and the plurality of igniters to activate each of first and second gas burners among the plurality of gas burners for respective first and second predetermined activation durations.
