PURPOSE:To sensibly detect the abnormal temperature rising of a pot by a temperature fuse by forming a heat sensitive board, which is provided between the inside fine coiling part and outside fine coiling part of an induction coil, with the material of satisfactory heat conductivity to have elasticity and bringing into contact one part of the heat sensitive board with the bottom part of the pot when the pot is housed. CONSTITUTION:A protecting frame bottom part 3, a protecting frame side surface part 4 and an upper frame 5, which constitute the housing part of a pot 2, are arranged in the internal part of a cooker main body 1 and a heat sensing part 11, for which a thermister, etc., is built in, is arranged in the center of the protecting frame bottom part 3. Temperature information to be sensed by the heat sensing part 11 are transmitted to an electric circuit 13 and the control of an induction coil 7 and a heater 10 is executed. However, a heat sensitive board 14 to be formed by the material of the satisfactory heat conductivity to have the elasticity is provided in the protecting frame bottom part 3 between an inside fine coiling part 7a and an outside fine coiling part 7b of the induction coil 7 and one part of the heat sensitive board forcibly is brought into contact with elastic force to the bottom part of the pot 2 when the pot 2 is housed. Then, a temperature fuse 15 is fitted to the heat sensitive board 14. Accordingly, when the temperature of the pot abnormally rises up, the highest temperature of the pot bottom part can be transmitted to the temperature fuse and the electric circuit can be safely interrupted. |
