<P>PROBLEM TO BE SOLVED: To provide a heating cooking device that is properly interlocked with a ventilator. <P>SOLUTION: When a ventilation signal is output to the ventilator, the fact to start the output is stored in a nonvolatile memory 156b, and after completion of the output, the fact is stored in the nonvolatile memory 156b. At restarting, the nonvolatile memory 156b is referenced, and if outputting of the ventilation signal is not yet completed, electric power supplied from a power supply battery 152 is discharged. Since the voltage of the power supply battery 152 drops and an operation voltage drops thereafter, the fact is displayed on a display device 154c, and a user is encouraged to replace the power supply battery 152. As a result, such a state as the ventilator is properly interlocked can be maintained without newly adding a circuit for monitoring a voltage drop that accompanies outputting of the ventilation signal, nor adding a device for reporting the occurrence of the voltage drop. <P>COPYRIGHT: (C)2012,JPO&INPIT |
