Abstract
Boil dry conditions are detected in utensils heated on a glass-ceramic cooking appliance having at least one heating unit disposed under a glass-ceramic plate by monitoring the level of power supplied to the heating unit. A power level detector is electrically connected to the heating unit and generates a signal representative of the power level. A controller for controlling the heating unit so as to prevent the glass-ceramic plate from exceeding a maximum temperature is arranged to receive the power signal. The controller provides a boil dry indication in response to a decrease in the power signal. Alternatively, the controller can monitor the level of power being supplied to the heating unit by monitoring a signal generated to control the level of power, thereby eliminating the power level detector.
