<p>A scorch detection unit (6) which detects scorched food on the bottom of a pot (1) carries out a scorch detection operation for detecting scorched food on the bottom of the pot (1) using a first output voltage when an infrared sensor (5) detects that the rate of increase in an output voltage, which is output corresponding to the temperature of the base of the pot (1), is at least a predetermined rate of increase during an operation time from the initialisation of cooking and before the expiration of a predetermined threshold time (T). If the scorch detection unit (6) detects that the rate of increase does not reach the predetermined rate of increase, and if a second output voltage which is set lower than the first output voltage is reached, scorched food is detected on the bottom of the pot (1). Thus, the scorch detection unit (6) can use a scorch detection function in an automatic response to the viscosity of the food to be cooked.</p> |
