Abstract
An infrared radiation detector is provided for receiving an infrared radiation emitted from a material being cooked placed in a cooking chamber in a microwave oven. The microwave oven is provided with a keyboard, a digital display and a microcomputer, such that when a temperature operation mode is set by entry from the keyboard the set temperature data is stored in a memory. In the temperature operation mode, the temperature of the material being cooked is detected in terms of a voltage associated with the output from the infrared radiation detector and a magnetron of the microwave oven is energized until the above described detected voltage becomes equal to the set temperature data and the magnetron is deenergized when both coincide with each other. In the temperature operation mode the temperature of the material being cooked is displayed by the digital display.
