Abstract
A method of operating a cooktop appliance includes inputting a temperature measurement and a set temperature into a closed-loop control algorithm. When the output of the closed-loop control algorithm is less than a power level threshold, a first control valve to a gas burner of the cooktop appliance is closed.
Claims18
A method of operating a cooktop appliance, the cooktop appliance comprising a gas burner, the method comprising:
- receiving a user-determined set temperature from a user interface of the cooktop appliance;
- activating the gas burner;
- receiving a precision mode initiation signal from the user interface;
- receiving a temperature measurement from a temperature sensor configured to measure a temperature at a utensil heated by the gas burner;
- inputting the user-determined set temperature and the temperature measurement into a closed-loop control algorithm, whereby the closed-loop control algorithm produces an output based on the user-determined set temperature and the temperature measurement;
- comparing the output of the closed-loop control algorithm to a threshold power level;
- closing a first control valve to the gas burner when the output of the closed-loop control algorithm is less than the threshold power level;
- and
- starting a burner OFF time count after closing the first control valve and opening the first control valve when the burner OFF time count is greater than a minimum OFF time and the output of the closed-loop control algorithm is greater than the threshold power level.
