| description | PROBLEM TO BE SOLVED: To securely stop power supply from an AC power source to a heater and to an induction heating coil when a temperature fuse is broken in a configuration not to distribute a heater current to the temperature fuse within a lid.SOLUTION: The induction heating rice cooker includes: a relay 61 for connecting or disconnecting a current pathway to the AC power source, an inverter circuit 32 and the heater 66; the temperature fuse 60 for detecting a value corresponding to the temperature of the heater and disconnected when the detected value exceeds a prescribed value; a first DC power source circuit to which the power is supplied from the AC power source via the temperature fuse to convert the power to DC power source; and a second DC power source circuit 64 to which the power source voltage is supplied from the first DC power source circuit to change the voltage to a voltage value lower than the output voltage of the first DC power source circuit 59. The first DC power source circuit is configured to output the voltage of at least about two times of the threshold voltage of a gate terminal of a semiconductor switching element. A control part is supplied with the power source voltage from the second DC power source circuit, and a drive circuit, the relay and a triac drive circuit are supplied with the electric power from the first DC power source circuit. |
