In addition, the set cooking modes 72 and 73 are displayed on the corresponding display window 71 for the burner 21, and the remaining time (return limit time) 76 until automatic cooking is canceled is displayed. As described above, when automatic cooking is interrupted by turning off the main power supply by the power switch 41, the main power supply is turned on again by the power switch 41 so that the automatic cooking can be restored easily. Then, the display of the information display unit 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 burner 21 (ST31 to ST32, display E in FIG. 7).

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

  When the main power supply is turned off by the power switch 43 within the above-mentioned return time limit (Yes in step ST36), the entire display on the information display unit 41 is turned off and the operation is ended (ST36, ST25). .

  Thus, according to the heating cooker 1, even if the fire extinguishing operation or the main power-off operation is performed unintentionally during 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 with the main power turned on and the corresponding burners 21 and 31 are ignited, automatic cooking can be resumed from the state at the time of interruption, so the heating power and combustion time of the burners 21 and 31 can be reduced. There is no need to manually set it again. Therefore, it is easy to use. In addition, since it is not necessary for the user to determine the remaining heating amount or heating time of the object to be heated, variations in the finished cooking state are unlikely to occur.

  Furthermore, if automatic fire extinguishing operation or main power-off operation is performed unintentionally during automatic cooking, and automatic cooking is interrupted, automatic cooking such as a warning message to that effect and the setting cooking mode of the corresponding burners 21 and 31 is performed. Along with the interruption information, the time limit for returning until automatic cooking is canceled is displayed or voiced, so that the user can restart automatic cooking from the interruption time, and which burner 21, It is possible to clearly recognize whether it is necessary to return the 31 automatic cooking. Therefore, usability is even better.

  In the above embodiment, the control operation at the time when automatic cooking is interrupted in the stove burner 21 has been described, but the same control operation at the time when automatic cooking is interrupted is also performed in the grill burner 31.

  Moreover, in the said embodiment, it was comprised so that an automatic cooking return function might be cancelled | released by the OFF operation of the cancellation | release switch 48 provided in the setting operation panel 40 in order to switch cancellation | release and setting of an automatic cooking return function. However, the automatic cooking return function may be canceled by a specific operation of the setting input switch 46 such as long pressing of the setting input switch 46 or multiple simultaneous pressings of the setting input switch 46.

  Further, in the above embodiment, a description has been given of a case where a burner using gas combustion exhaust gas as a heat source is used as a heating means for heating an object to be heated. An electric heater that heats the object to be heated by heat may be used, or an electromagnetic induction heater that heats the object to be heated by electromagnetic induction may be used. A burner, an electric heater, or an electromagnetic induction heater may be used in combination.
