かることができる。According to the above-described structure of the present invention, a part of the container (2), at least the magnetic induction heating section, is made of magnetic ferrite whose Curie temperature has been selected.
By selecting and setting the temperature at a predetermined temperature, when the heating temperature reaches the predetermined Curie temperature, the container (2) loses its magnetism and no longer generates magnetic induction in the container (2), thereby stopping the heating. Therefore, since this Curie temperature becomes the upper limit temperature, it is possible to prevent overheating of the container (2) and, by extension, the electromagnetic cooker (1). Or,
If you select this Curie temperature according to the specific cooking purpose, for example, if you make a container for tempura, for warming sake, for half-boiled boiled eggs, etc., the temperature will automatically reach the optimum cooking temperature. The temperature can be controlled to simplify cooking.

, Ni-1n ferrite, and Mg-Zn ferrite, and the hard magnetic ferrite is CO-containing r-Fe203, B
A ferrite, Sr ferrite, etc. can be used. Here, soft magnetic ferrite has a high Curie point, so the mixing ratio of soft magnetic ferrite to hard magnetic ferrite, that is, Z
The Curie temperature can be adjusted and selected by selecting the amounts of n and Fe added. Then, the heating upper limit temperature is set by adjusting this Curie temperature. For example, if the Curie temperature is 260°C, when the heating state reaches 260°C, the container (2) loses its magnetism, causing induction heating, that is, generation of Joule heat due to the generation of eddy currents, and heating due to hysteresis loss. It disappears. For example, when configuring containers for different uses, by selecting a Curie temperature of 260°C, a tempura cooking container, a 90°C container for soft-boiled eggs, a 40°C container for sake sake, etc. are constructed.

Furthermore, in the above example, the entire container (2) is formed of a mixed ferrite of hard magnetic ferrite and soft magnetic ferrite selected to have a predetermined Curie temperature.
In 2), the mixed ferrite can also be formed by molding multicolored ferrite so that it is formed of non-magnetic ferrite that performs magnetic induction.
