Notifying by notification means together with interruption information, and restarting automatic cooking based on the operation information at the time of interruption, when automatic cooking return operation is performed between the interruption time of automatic cooking reaches the return limit time; It is a heating cooker configured to stop the notification at the same time.

In this case, even if automatic cooking is interrupted due to an unintentional heating-off operation or an operation to turn off the main power during automatic cooking, the automatic cooking return operation is performed within the recovery time limit and the heating means is turned on automatically. Since it has an automatic cooking return function that resumes cooking from the state at which it was interrupted, there is no need to manually set the output heat amount or turn-on time of the heating means again, and there is no need for the user to determine the remaining amount of heating or heating time. .

Preferably, the heating cooker includes a notification means for notifying the operation information of the appliance body or the heating condition set by the setting input means, and a heating off operation or a main power off operation is performed during automatic cooking execution. In this case, the return limit time during which automatic cooking can be resumed is notified by the notification means together with automatic cooking stop information indicating that the heating means has been turned off during automatic cooking execution, and the interruption time of automatic cooking is set to the return limit time. It is set as the structure which stops the said notification when the automatic cooking return operation is made|formed during the time of arrival.

In addition, in this case, when automatic cooking is interrupted due to an unintentional turning off operation of heating or an operation of turning off the main power during automatic cooking, automatic cooking is performed together with automatic cooking stop information indicating that the heating means is turned off. By notifying the resumable time limit for resuming automatic cooking, it is possible to make it clear to the user that automatic cooking can be resumed from the time of interruption, or when it is necessary to perform automatic cooking return processing.

Also, preferably, in the heating cooker, when a predetermined release operation is performed, the automatic cooking return function for resuming automatic cooking based on operation information at the time of interruption is canceled.

In this case, if the automatic cooking return function is canceled, even if the heating off operation or the main power off operation is executed during automatic cooking, the automatic cooking interruption information or the return time limit is not notified. It is possible to solve the inconvenience of being notified of automatic cooking interruption information or recovery time limit despite the operation of turning off the heating or the operation of turning off the main power.

As described above, according to the present invention, even if the heating means is unintentionally turned off during automatic cooking, if it is within the return limit time, it is not necessary to set the output heat amount or the on time of the heating means again. . In addition, since there is no need for the user to determine the remaining heating amount or heating time, it is difficult to cause a difference in the finished state of cooking.

On the other hand, if the main power is turned on by the power switch 43 within the recovery time limit (Yes in step ST31), instead of the warning message 75, the remaining time 76, and the recovery procedure 77 , a display window 71 for displaying the heating conditions for each burner 21 and 31 is displayed again on the information display unit 41 . In addition, the set cooking mode 72, 73 is displayed on the display window 71 for the corresponding stove burner 21, and the remaining time until automatic cooking is canceled (return limit time) 76 is displayed. . As described above, when the automatic cooking is interrupted by the operation of turning off the main power by the power switch 41, the main power is turned on again by the power switch 41 so that the automatic cooking can be easily restored. In step, the display of the information display unit 41 is switched to a state in which the display window 71 of the corresponding stove burner 21 displays the remaining time 76 until automatic cooking is canceled (ST31 to ST32, Fig. Mark of 7 E).

Also, when the re-ignition operation of the furnace burner 21 is performed within the recovery time limit (Yes in step ST33), the corresponding furnace burner 21 is ignited similarly to step ST5. In addition, instead of the remaining time 76 until the automatic cooking is canceled, the required time 74 until the end of cooking is displayed on the information display unit 41, and the automatic cooking is resumed based on the operation information at the time of interruption. (ST33 to ST35, display B in Fig. 7).

If the operation of turning off the main power is performed by the power switch 43 within the recovery time limit (Yes in step ST36), all displays on the information display unit 41 are turned off, and the operation is terminated (ST36, ST25). ).

As such, according to the heating cooker (1), even when automatic cooking is interrupted due to an unintentional fire extinguishing operation or an operation to turn off the main power during automatic cooking, the main power is turned on as an automatic cooking return operation within the return time limit. If the ignition operation is performed in this state and the corresponding burners 21 and 31 are ignited, automatic cooking can be resumed from the state at the time of interruption. No need to set So, writing is good. In addition, since there is no need for the user to determine the remaining heating amount or heating time of the object to be heated, it is difficult to cause a difference in the finished state of cooking.

And, when automatic cooking is stopped due to an unintentional fire extinguishing operation or an operation to turn off the main power during automatic cooking, a warning message indicating the fact or automatic cooking interruption such as the setting cooking mode of the corresponding burners 21 and 31 In addition to information, the return time limit until automatic cooking is canceled is notified by display or voice, so that the user can resume automatic cooking from the time of interruption, or automatic cooking of any burners 21 and 31 until a certain point. You can clearly recognize the need for a return. Therefore, the convenience of use is further improved.

Incidentally, in the above embodiment, although the control operation at the time of interruption of automatic cooking in the furnace burner 21 has been described, the same control operation at the time of interruption of automatic cooking is performed in the grill burner 31 as well.

In addition, in the above embodiment, it has been described that the automatic cooking return function is canceled by turning off the release switch 48 installed on the setting operation panel 40 in order to cancel and switch the setting of the automatic cooking return function. It may be configured such that the automatic cooking return function is canceled by a specific operation of the setting input switch 46, such as a long press of the setting input switch 46 or a plurality of simultaneous presses.

Further, in the above embodiment, as the heating means for heating the object to be heated, it has been described that a burner using the combustion exhaust gas of the gas as a heat source is used. An electric heater for heating water may be used, or an electromagnetic induction heater for heating an object to be heated by electromagnetic induction may be used. Moreover, a burner, an electrothermal heater, and an electromagnetic induction heater may be combined and used.
