Abstract
A gas cooktop may include: a gas burner; a sensor configured to sense temperature of a cooking container heated by the gas burner; a valve configured to control flow rate of gas from a gas source to the gas burner; and a control system including circuitry. The control system may start operation of the gas burner; receive sensor signals from the sensor indicating the temperature of the cooking container; and based on received sensor signals representing the sensed temperature of the cooking container and a cooking profile indicating one or more durations and one or more temperatures, control the valve to change the gas flow rate to the gas burner.
Claims20
A gas cooktop comprising:
- a gas burner;
- a sensor configured to sense temperature of a cooking container heated by the gas burner;
- a valve configured to control flow rate of gas from a gas source to the gas burner;
- and
- a control system including circuitry, the control system configured to:
- start operation of the gas burner;
- receive sensor signals from the sensor indicating the temperature of the cooking container;
- and
- based on received sensor signals representing the sensed temperature of the cooking container and a cooking profile indicating one or more durations and one or more temperatures, control the valve to change the gas flow rate to the gas burner,
- wherein the cooking profile identifies a first and a second temperature, a first duration for the first temperature, and a second duration for the second temperature.
A gas cooktop, comprising:
- a plurality of gas burners;
- a grate disposed above an upper portion of the plurality of gas burners;
- a plurality of temperature sensors, each temperature sensor disposed above a corresponding gas burner and configured to abut a bottom surface of a cooking container when the cooking container is placed on the grate above the corresponding gas burner;
- a plurality of proportional solenoid valves, each valve configured to control flow rate of gas from a gas source to the corresponding gas burner;
- and
- a control system including one or more processors, the control system configured to:
- receive user input specifying a cooking profile and assigning the cooking profile to a selected gas burner of the plurality of gas burners, the cooking profile including a first temperature, a first duration for the first temperature, a second temperature, and a second duration for the second temperature;
- while operation of the selected gas burner during the first duration and the second duration, receive, from the temperature sensor associated with the selected burner, sensor signals indicating a surface temperature of the cooking container heated by the selected gas burner;
- during the first duration, control the valve to increase the flow rate when the surface temperature of the cooking container is below the first temperature and decrease the flow rate when the surface temperature of the cooking container is above the first temperature;
- and
- during the second duration, control the valve to increase the flow rate when the surface temperature of the cooking container is below the second temperature and decrease the flow rate when the surface temperature of the cooking container is above the second temperature.
