Abstract
A cooktop appliance includes an electric heating element positioned at a cooktop surface and a controller operably connected to the electric heating element. The controller is configured for generating a temperature setting and operating the electric heating element at a first power level. The controller is also configured for monitoring a temperature with a temperature sensor and inputting the monitored temperature into a closed control loop. The controller is further configured for operating the electric heating element at a second power level based at least in part on an output of the closed control loop.
Claims20
A cooktop appliance, comprising:
- an electric heating element positioned at a cooktop surface of the cooktop appliance;
- and
- a controller operably connected to the electric heating element, the controller configured for:
- generating a temperature setting;
- initiating a first cycle, the first cycle comprising applying a first voltage across the electric heating element and monitoring a temperature with a temperature sensor until the monitored temperature reaches a threshold temperature, the threshold temperature less than or equal to the temperature setting;
- and
- performing a second cycle when the monitored temperature reaches the threshold temperature, the second cycle comprising monitoring the temperature with the temperature sensor, calculating a difference between the monitored temperature and the temperature setting, applying a second voltage across the electric heating element over a first period of time, the second voltage less than the first voltage, and deactivating the electric heating element for a second period of time, wherein a duration of the first period of time is based on the calculated difference between the monitored temperature and the temperature setting.
