This remaining time is the time from the present time to the scheduled end time of the automatic cooking operation, and is continuously displayed from the start of the automatic cooking operation to the end of the automatic cooking operation. The scheduled end time of the automatic operation is determined by the control unit 60, for example, based on the cooking menu set by the grill operation unit 5. In addition, the scheduled end time is determined for each automatic cooking operation.

The control unit 60 executes the process of step S2 following the process of step S1 shown in FIG. 7. In step S2, the control unit 60 determines whether or not the end condition of the automatic cooking operation is satisfied. The end condition of the automatic cooking operation of the present embodiment is that the time during which the automatic cooking operation is executed exceeds a predetermined time, that is, the remaining time of the automatic cooking operation is exhausted. The time when the automatic cooking operation is executed does not include the time when the door opening operation is executed and the time when the return operation is executed. Further, the end condition of this automatic cooking operation is determined for each automatic cooking operation based on the cooking menu set by the grill operation unit 5. Further, the end condition of the automatic cooking operation is not limited to the time when the automatic cooking operation is executed exceeds a predetermined time. For example, the end condition of the automatic cooking operation may be that the execution time of the automatic cooking operation is at least a predetermined time and the temperature of the cooking container 4 detected by the temperature detection unit 27 is at least a predetermined temperature. .. Further, the end condition of the automatic cooking operation may be that the temperature of the cooking container 4 detected by the temperature detection unit 27 has reached a predetermined temperature or more a plurality of times.

When the end condition of the automatic cooking operation is satisfied in step S2, the control unit 60 ends the automatic cooking operation with the upper burner 30 and the lower burner 31 in the fire extinguishing state in step S3. When the end condition of the automatic cooking operation is not satisfied in step S2, the control unit 60 executes the process of step S4.

In step S4, the control unit 60 detects the open / closed state of the door 14 by the open / close detection unit 61, and determines whether or not the door 14 is in the open state. When it is detected in step S4 that the door 14 is not in the open state (that is, in the closed state), the control unit 60 waits for a certain period of time in step S5 and then executes the process of step S2.

When it is detected in step S4 that the door 14 is in the open state, the control unit 60 suspends the automatic cooking operation in step S6 and starts the door opening operation. At the start of this door opening operation, the control unit 60 controls the heating amount changing unit 33 to put the upper burner 30 in a fire extinguishing state and set the thermal power of the lower burner 31 to "weak". In the door opening operation of the present embodiment, the control unit 60 does not change the heating amount of the heating unit 3. That is, the control unit 60 maintains the fire extinguishing state of the upper burner 30 and keeps the thermal power of the lower burner 31 "weak" during the door opening operation. In the door opening operation of the present embodiment, the upper burner 30 is in the fire extinguishing state, but the upper burner 30 may be in the ignition state. Further, in the door opening operation of the present embodiment, the upper burner 30 is in the fire extinguishing state and the lower burner 31 is in the ignition state, but both the upper burner 30 and the lower burner 31 may be in the fire extinguishing state.

During the door opening operation, the control unit 60 does not count the execution time of the automatic cooking operation. Further, during the door opening operation, the control unit 60 informs the user that the door opening operation is in progress, that is, that the automatic cooking operation is temporarily stopped and the door 14 is open. Notify. The notification by the notification unit 62 is performed by changing the display by the display unit 53 to a display different from that during the automatic cooking operation and by sounding by the sounding unit 63.

The display unit 53 notifies that the door is being opened, for example, by displaying the remaining time of the automatic cooking operation as a blinking display. In this case, the control unit 60 displays, for example, the remaining time at the time of pausing the automatic cooking operation as the remaining time of the automatic cooking operation by the display unit 53. Further, the sounding unit 63 notifies that the door is being opened by, for example, issuing an alarm sound at predetermined time intervals. Note that the notification that the door is being opened by the notification unit 62 is not limited to the embodiment of the present embodiment as long as the user can recognize that the door is being opened.

Further, the control unit 60 detects the temperature T of the cooking container 4 by the temperature detection unit 27 in the process of step S6 for starting the door opening operation, and stores this temperature T as the door opening temperature TO in a memory or the like. .. That is, the door opening temperature TO is the temperature of the cooking container 4 at the start of the door opening operation.

The control unit 60 executes the process of step S7 following step S6. In step S7, the control unit 60 detects the open / closed state of the door 14 by the open / close detection unit 61, and determines whether or not the door 14 is in the closed state. When it is detected in step S7 that the door 14 is not in the closed state (that is, it is in the open state), the control unit 60 waits for a certain period of time in step S8 and then executes the process of step S7.

When it is detected in step S7 that the door 14 is in the closed state, the control unit 60 ends the door opening operation and starts the return operation in step S9. The control unit 60 controls the heating amount changing unit 33 at the start of this return operation, and makes the thermal power of the lower burner 31 “strong” while maintaining the fire extinguishing state of the upper burner 30. In the return operation of the present embodiment, the control unit 60 does not change the heating amount of the heating unit 3. That is, the control unit 60 maintains the fire extinguishing state of the upper burner 30 and keeps the thermal power of the lower burner 31 "strong" during the return operation.

During the return operation, the control unit 60 notifies the user that the return operation is in progress by the notification unit 62. The notification by the notification unit 62 is performed by making the display by the display unit 53 different from the display during the automatic cooking operation and the door opening operation. The display unit 53 notifies that the return operation is in progress by displaying, for example, a character or a symbol indicating that the return operation is in progress. Note that the notification of the return operation by the notification unit 62 is not limited to the embodiment of the present embodiment as long as the user can recognize that the return operation is in progress.

The control unit 60 executes the process of step S10 following step S9. In step S10, the control unit 60 detects the temperature T of the cooking container 4 by the temperature detection unit 27, and determines whether or not this temperature T is equal to or higher than the temperature TO at the time of opening the door. If the temperature T detected by the temperature detection unit 27 in step S10 is not equal to or higher than the door opening temperature TO (if it is less than the door opening temperature TO), the control unit 60 waits for a certain period of time in step S11 and then steps. The process of S10 is executed.

If the temperature T detected by the temperature detection unit 27 in step S10 is equal to or higher than the door opening temperature TO, the control unit 60 ends the return operation in step S12 and restarts the automatic cooking operation.

When the automatic cooking operation is restarted, the control unit 60 restarts the counting of the execution time of the automatic cooking operation. The control of the automatic cooking operation after the restart is the same as the control of the automatic cooking operation before the restart. That is, when the temperature T detected by the temperature detection unit 27 is less than the predetermined temperature TA, the control unit 60 becomes “strong” in each of the upper burner 30 and the lower burner 31, and when the temperature is equal to or higher than the predetermined temperature TA, the control unit 60 becomes “strong”. The heating amount changing unit 33 is controlled so that the thermal power of the upper burner 30 becomes “strong” and the thermal power of the lower burner 31 becomes “weak”.

The control unit 60 executes the process of step S2 following the process of step S12. That is, in the present embodiment, the door opening operation and the returning operation are executed even when the door 14 is opened during the restarted automatic cooking operation.

As described above, by executing the return operation after the door opening operation, the temperature of the cooking container 4 at the time of resuming the automatic cooking operation is changed to the temperature of the cooking container 4 at the time when the automatic cooking operation is temporarily stopped (that is, opening). The temperature at the door can be set to TO). Therefore, even though the door 14 is opened during the automatic cooking operation, it is difficult for the cooking object to be burnt or the like, and cooking by the automatic cooking operation can be appropriately performed. Further, in the return operation of the present embodiment, of the upper burner 30 and the lower burner 31, only the lower burner 31 is set to the ignition state, and the upper burner 30 is set to the fire extinguishing state. Therefore, for example, when the automatic cooking operation is performed with the cooking object arranged in the cooking container 4 exposed upward, the cooking object may be burned by the flame of the upper burner 30 during the return operation. It disappears. Therefore, when the return operation is executed, it is suppressed that the object to be cooked is unnecessarily burned by the flame of the upper burner 30, and it becomes possible to cook with a good finish.

Although the heating amount of the heating unit 3 in the return operation of the present embodiment is constant, it may be changed based on the detection result of the temperature detection unit 27 or the like. For example, the control unit 60 sets the heating amount of the heating unit 3 as the first heating amount until the temperature T detected by the temperature detecting unit 27 reaches an intermediate temperature lower than the door opening temperature TO during the return operation. From the time when the temperature T reaches the intermediate temperature to the time when the door opens temperature TO, the heating amount of the heating unit 3 may be set to the second heating amount smaller than the first heating amount. For example, the first heating amount is the heating amount of the heating unit 3 when the upper burner 30 is in the fire extinguishing state and the heating power of the lower burner 31 is set to "strong", and the second heating amount is the heating amount of the upper burner 30. It is the heating amount of the heating unit 3 when the fire is extinguished and the thermal power of the lower burner 31 is set to "weak". By changing the heating amount of the heating unit 3 during the return operation in this way, it is possible to prevent the cooking container 4 from being heated more than necessary in the return operation, and after the return operation is completed (after the automatic cooking operation is restarted). In addition, it is possible to prevent the temperature of the cooking container 4 from rising beyond the temperature TO when the door is opened.
