なお、16は蓋体で、フックレバー17により開閉される。In FIG. 1 and FIG. 2, inside the cooker main body 1, a protective frame bottom portion 3, a protective frame side surface portion 4 and an upper frame 5 which constitute a storage portion for the pan 2 are arranged. The protective frame bottom 3 is made of a non-metallic material. The pot 2 is formed of, for example, a clad steel plate having an outer surface made of a magnetic material and an inner surface made of aluminum. The pot 2 is supported by bringing the upper end flange portion 6 into contact with the upper frame 5. Induction coil 7
On the outer surface of the bottom 3 of the protective frame, the inner close-wound portion 7a and the outer close-wound portion 7b.
They are divided into two parts, and are held between them and the protective frame cover 8. The ferrite 9 is attached to the outer surface of the protective frame cover 8 to enhance the inductive coupling and to prevent the outside from being magnetized. On the side surface 4 of the protective frame, for example, a heater 10 having insulation covering is attached. Further, in the center of the bottom 3 of the protective frame, there is provided a heat sensitive portion 11 having a built-in thermistor, for example, and this heat sensitive portion 11 is biased by a sensor spring 12 and comes into contact with the bottom portion of the pot 2 to cook the pot. The bottom temperature of 2 is detected. And this heat sensitive part 11
The temperature information detected by is transmitted to the electric circuit 13 to control the induction coil 7 and the heater 10. A heat sensitive plate 14 made of a material having good heat conductivity, such as aluminum, is provided on the bottom 3 of the protective frame, located between the inner close-wound portion 7a and the outer close-wound portion 7b of the induction coil 7. Further, the heat sensitive plate 14 is provided with a temperature fuse 15, which is a heat sensitive operating body that interrupts the electric circuit 13 when the temperature rises abnormally.
Reference numeral 16 is a lid, which is opened and closed by a hook lever 17.

ものである。FIG. 3 shows another embodiment of the present invention. In this embodiment, since the lower surface of the thermal fuse 15 is covered with the pressing plate 18, the heat received by the thermal fuse 15 from the heat sensitive plate 14 is downward. It is possible to reduce the amount of heat radiated by the pressing plate 18, and thus the sensitivity of the thermal fuse 15 can be improved. In addition, the temperature fuse 15 is attached to the heat sensitive plate by the pressing plate 18.
Since the heat-sensitive plate 14 is attached to the protective frame bottom portion 3 by the pressing plate 18 while being pressed against the pressure-sensitive plate 14, the structure thereof is extremely simplified and the attaching work can be easily performed.
