安全性等を向上できる。As described above, in the present embodiment, between the top plate 4 and the induction coil 6 is made of a material having heat resistance and a line of magnetic force is permeable, and is at least larger in diameter than the induction coil 6. By providing the induction coil protection plate 13 formed in the above, for example, pots and the like are dropped on the top plate 4,
Even if the top plate 4 is damaged due to this impact while the induction coil 6 is energized, the induction coil 6 is not exposed.
Therefore, the induction coil 6 will not be accidentally touched by a hand or the like. Further, the fragments of the top plate 4 do not reach the induction coil 6 by being blocked by the induction coil protection plate 13, and the conductor wire of the induction coil 6 is cut, the insulating layer is peeled off, or the insulating layer is cracked. There is nothing to do. Therefore, it is possible to prevent the cutting of the conductive wire, the peeling or cracking of the insulating layer, and the like, so that it is possible to prevent the occurrence of short circuit, electric shock, and electric leakage. Further, when a pot containing water or the like is dropped on the top plate 4, there is a risk that water or the like will enter through cracks in the top plate 4, but the induction coil 6 is wet by the induction coil protection plate 13. This can prevent the occurrence of short circuit, electric shock, and electric leakage. Furthermore, the fragments of the top plate 4 are not covered with the induction coil support base 7.
Since it does not reach the circuit board 35 arranged below the circuit board, damage to the circuit board 35 can be prevented. In particular, in the above-described embodiment, the through hole 5 in which the temperature sensor support 19 appears and disappears in the top plate 4.
Since the top plate 4 made of crystallized glass is slightly inferior in mechanical strength and impact resistance, since the induction coil protection plate 13 is provided as described above, the top plate 4 is not damaged. The safety etc. can be improved.

Further, in the embodiment, the induction coil protection plate 13 has a diameter larger than that of the induction coil support base 7, but the induction coil protection plate 13 has a diameter larger than that of the top plate, and is entirely below the top plate. An induction coil protection plate is provided so as to prevent the induction coil from being exposed when the induction coil protection plate is damaged, and the outer edge of the induction coil protection plate and the top plate mounting hole 2A of the upper body are provided. It may be possible to prevent water or the like from entering the circuit board in the cooker body from the seam. Further, in the embodiment, the flange portion 21 abuts on the short tubular portion 15 of the induction coil protection plate 13 to prevent the temperature sensor support body 19 from being pulled out, but the flange portion penetrates the top plate or the induction coil support base. Various modifications are possible such that the temperature sensor support may be prevented from coming off by contacting the hole.
