Abstract

PURPOSE: To simplify the structure without requiring battery for temperature detector by receiving microwave delivered from a magnetron with an antenna of heat-sensitive needle and connecting a wave detecting means and a constant voltage generating means in series to the antenna.
CONSTITUTION: A temperature detector 5 is inserted into the food F placed in an oven 1, and microwaves are radiated from a magnetron 4. These microwaves are received by an antenna 7, causing a constant voltage V4 to be delivered from a power generating circuit 11. This power becomes the driving power for a heat- sensitive element 15, transducer 16 and transmitter 17. This transmitter 17 outputs this power in the form of a carrier wave P3. A receiver 8 receives this carrier wave P3, and it is sent to a control circuit 9 as an electric signal P4 to indicate temperature information. When the detected temperature of the food F of heat-sensitive element 15 meant by this electric signal P4 coincides with the predetermined temperature, the control circuit 9 applies a stop signal P5 to the magnetron 4 to stop its driving
