Abstract
A cooking apparatus determining a temperature of food to be cooked by detecting the changes in the intensity of the infrared rays from the food. The cooking apparatus includes an infrared ray detecting circuit having a detecting element which detects infrared rays from the food. When the actual temperature change in the vicinity of the detecting element is more than a predetermined value, the detecting element is prevented from receiving the infrared rays from the food. The detecting element detects the actual temperature, and the infrared ray detecting circuit outputs the corresponding detection value. The detection value from the infrared ray detecting circuit is stored in a control circuit. The output of the infrared ray detecting circuit is corrected by the stored detection value when the detecting element is exposed to the infrared rays from the food in order to carry out a precise temperature detection for the food.
