A microwave oven is provided with a turntable for turning food and a radiation detection device for detecting radiation emitted from food without making contact with it so as to control its temperature. The radiation detecting device includes a radiation detector and a scanning reflecting mirror which linearly scans the turntable diametrically thereof and re-directs a beam of radiation through a chopper to the radiation detector. Because of the composition of the rotation of the turntable and the scanning movement of the reflecting mirror and of the chopper, a temperature at a very small spot on food may be detected so that regardless of the kind, shape and volume of food on the turntable, the temperature of food may be always detected with a higher degree of accuracy.

Microwave oven having radiation detector

A microwave oven, provided with a turning tray disposed in a cooking chamber in an oven case for uniform heating of the cooked object, wherein

Microwave oven

A temperature detecting unit extended, through a cable, from an inside wall of the microwave oven has a probe formed at end portion thereof for inserting the probe into an object such as food items to be heated for detecting the temperature of the object during the heating, so as to produce a signal indicative of the temperature of the object. The cable of the temperature detecting unit is formed by comparatively thin wires having sufficient flexibility and durability so as to facilitate the manipulation of the unit during inserting thereof into the object.
