<P>PROBLEM TO BE SOLVED: To indicate an on-off state of a power switch in an easy-to-understand manner calling attention to a high temperature. <P>SOLUTION: When a power switch 6 for providing or cutting off a power supply to heating coils 2 is in an on state and at least one of a plurality of temperature detection parts 3 respectively detecting temperatures of a top plate 1 around directly above the heating coils 2 and arranged in vicinity of respective heating coils 2 which are halted to heat detects a high temperature of the top plate 1, a ring-shaped light-emitting display part 4 surrounding an outer periphery of the heating coil 2 corresponding to the temperature detection part 3 that detects the high temperature transitions to a first display state. When the power switch 6 is in an off state and at least one of the plurality of temperature detection parts 3 detects a high temperature of the top plate 1, the light-emitting display part 4 surrounding an outer periphery of the heating coil 2 corresponding to the temperature detection part 3 that detects the high temperature transitions to a second display state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
