Abstract
A method for operating a cooktop appliance is provided. The method includes determining a temperature of a cooking utensil positioned on a heating element of the cooktop appliance, as well as determining a temperature of a food in the utensil positioned on the heating element of the cooktop appliance. The method also includes calculating a temperature differential between the temperatures of the food in the cooking utensil and of the cooking utensil itself. Subsequently, the method includes controlling a heating temperature of the heating element to reduce the temperature differential when the temperature differential is greater than a predetermined threshold to, e.g., reduce a risk of burning a portion of the food in the utensil.
Claims19
A method for operating a cooktop appliance, comprising:
- determining a temperature of a cooking utensil positioned on a heating element of the cooktop appliance with a cookware temperature sensor, wherein the cookware temperature sensor is attached to the cooking utensil, integrated into the cooking utensil, or contacting the cooking utensil;
- determining a temperature of a food in the cooking utensil positioned on the heating element of the cooktop appliance with a food temperature sensor;
- calculating a temperature differential between the temperature of the cooking utensil and the temperature of the food in the cooking utensil;
- and
- controlling a heating temperature of the heating element to reduce the temperature differential when the temperature differential is greater than a predetermined threshold.
A cooktop appliance comprising:
- a heating element positioned on a cooktop surface of the cooktop appliance;
- and
- a controller operably connected to the heating element, the controller configured to
- receive a signal from a cookware temperature sensor indicative of a temperature of a cooking utensil positioned on the heating element, wherein the cookware temperature sensor is attached to the cooking utensil, integrated into the cooking utensil, or contacting the cooking utensil when the cooking utensil is positioned on the cooktop surface;
- receive a signal from a food temperature sensor indicative of a temperature of a food positioned in the cooking utensil positioned on the heating element;
- calculate a temperature differential between the temperature of the cooking utensil and the temperature of the food in the cooking utensil;
- and
- control a heating temperature of the heating element to reduce the calculated temperature differential when the calculated temperature differential is greater than a predetermined threshold.
