PURPOSE: To provide an electromagnetic induction heating jar rice boiler in which the erroneous judgment of presence of an inner pan by the temperature rise of an equipment body is never caused with an inexpensive structure. CONSTITUTION: The outputs of an inner pan detecting circuit 6 for detecting the presence of an inner pot 5 and a temperature sensor 9 for detecting the equipment internal temperature are inputted to a microcomputer 8, the microcomputer 8 changes the threshold of judgment level for the presence or absence of the inner pot 5 to the input from the inner pot detecting circuit 6 according to the output value (temperature) of the temperature sensor 9, and the temperature sensor 9 for detecting the equipment internal temperature is used also as a temperature sensor used for the control of rice boiling. |
