Abstract: A cooktop includes a power adjustment switch with power grades, a power detection apparatus, a control apparatus, and an adjustment apparatus. The power detection apparatus for detects a power grade to determine an operation period of the power grade and a power level corresponding to the power grade and outputting operation information including the operation period and the power level. The control apparatus calculates a first valid period based on the operation information, and determines whether the first valid period exceeds a first threshold period. When affirmative, the control apparatus outputs adjustment information for adjusting the power grade to reduce the power level. The adjustment apparatus adjusts the power grade based on the adjustment information to reduce the power level. The cooktop actively detects an operating status and adjusts a power grade, to avoid dry burning and potential safety risks.
