Abstract:
1. A device for avoiding an overshoot of a temperature inside a cookware on a cooktop by limiting a bottom temperature of the cookware, the device comprising: a temperature sensing clement measuring a surface temperature adjacent a bottom of the cookware on the cooktop; and a control device in combination with each of the temperature sensing element and the cooktop, the control device having a control algorithm modifying a power level of the cooktop as a function of both a sensed temperature adjacent the bottom of the cookware and a rate of change of the sensed temperature by reducing the power level at a lower temperature when the rate of change of the sensed temperature is greater than or equal to a threshold value than when the rate of change of the sensed temperature is less than the threshold value, and the control algorithm controlling the power level as a function of the sensed temperature, the rate of change of the sensed temperature, and a change in a slope of a temperature/time curve and increasing the power level when the slope of the temperature/time curve is negative.
