As described above, when the automatic cooking is interrupted by the operation of turning off the main power by the power switch 41, the operation of turning on the main power again by the power switch 41 is performed so that the operation of returning the automatic cooking can be easily performed. Then, the display of the information display section 41 is switched to a state in which the remaining time 76 until the automatic cooking is canceled is displayed on the display window 71 of the corresponding stove burner 21 (ST31 to ST32, display E in FIG. 7).

  Further, when the re-ignition operation of the stove burner 21 is performed within the return limit time (Yes in step ST33), the corresponding stove burner 21 is ignited as in the step ST5. Further, instead of the remaining time 76 until the automatic cooking is canceled, the required time 74 until the cooking is completed is displayed on the information display unit 41, and the automatic cooking is restarted based on the operation information at the time of interruption (ST33 to ST35; Display B in FIG. 7).

  If the main power is turned off by the power switch 43 within the above-mentioned return time limit (Yes in step ST36), all the displays on the information display section 41 are turned off, and the operation ends (ST36, ST25). .

  As described above, according to the heating cooker 1, even if the fire extinguishing operation or the main power off operation is performed unintentionally during the automatic cooking and the automatic cooking is interrupted, the automatic cooking return operation is performed within the return time limit. If the ignition operation is performed while the main power is turned on and the corresponding burners 21 and 31 are ignited, the automatic cooking can be resumed from the state at the time of interruption, so that the heating power and the burning time of the burners 21 and 31 can be reduced. No need to manually reset. Therefore, the usability is good. Further, since it is not necessary for the user to determine the remaining heating amount and the heating time of the object to be heated, the finished state of the cooking hardly varies.

  Further, when the automatic cooking is interrupted because the fire extinguishing operation or the main power OFF operation is performed unintentionally during the automatic cooking, the automatic cooking such as the caution message indicating the fact and the setting cooking mode of the corresponding burners 21 and 31 are performed. Along with the interruption information, the return limit time until the automatic cooking is canceled is displayed or notified by voice, so that the user can resume the automatic cooking from the time of the interruption, and by which time the burner 21, It is possible to clearly recognize whether it is necessary to return the automatic cooking of No. 31. Therefore, the usability is further improved.

  In the above embodiment, the control operation of the stove burner 21 when the automatic cooking is interrupted has been described. However, the same control operation of the grill burner 31 when the automatic cooking is interrupted is performed.

  In the above embodiment, the automatic cooking return function is released by turning off the release switch 48 provided on the setting operation panel 40 for releasing the automatic cooking return function and switching the setting. However, the configuration may be such that the automatic cooking return function is released by a specific operation of the setting input switch 46, such as long pressing of the setting input switch 46 or simultaneous pressing of a plurality of settings.

  Further, in the above-described embodiment, a burner using a combustion exhaust gas of gas as a heat source is used as a heating unit for heating an object to be heated. However, instead of the above-described burner, radiant heat or conduction from an electric heating unit is used. An electric heater for heating an object to be heated by heat may be used, or an electromagnetic induction heater for heating an object to be heated by electromagnetic induction may be used. Further, a combination of a burner, an electric heater and an electromagnetic induction heater may be used.
