It has a function to perform operation control related to thermal power adjustment), a function to control display of operation panels 13 and 16, and the like. The operation control (combustion operation control) of each of the stove burner 5 and the grill burner 8 is, more specifically, an on-off valve and a thermal power provided in a fuel supply path (not shown) corresponding to each of the stove burner 5 and the grill burner 8. It is done through the operation control of the control valve and the ignition device (not shown).

In addition, the control device 20 is provided with a storage unit 20a that stores and holds information on the object to be cooked and cooking progress information, which will be described later. Supplementally, the control device 20 may be configured to be able to communicate with a communication terminal such as a smartphone, a tablet terminal, or a feature phone. In this case, it is possible to perform the same operation on the communication terminal as the operation that can be performed on the operation panels 13 and 16.

Next, the operation when the automatic cooking using any of the stove burners 5 is executed by the heating cooker 2 will be described. In this case, the control device 20 executes the process shown in the flowchart of FIG.

In STEP 1, the control device 20 repeats the determination process of whether or not the start operation of the automatic cooking operation has been performed until the determination result becomes affirmative. Here, when the user intends to cause the heating cooker 2 to execute an automatic cooking operation using any of the stove burners 5, a predetermined operation (menu selection operation, cooking) for starting the automatic cooking operation is performed. (Condition setting operation, etc.) is executed on the stove operation panel 13, or is executed on a communication terminal (not shown) capable of communicating with the control device 20. Correspondingly, the judgment result of STEP1 becomes affirmative.

When the determination result of STEP1 becomes affirmative, the control device 20 then, in STEP2, has the ignition operation of the stove burner 5 (hereinafter sometimes referred to as the first target stove burner 5) used in the automatic cooking operation been performed? The determination process for determining whether or not (in other words, whether or not the combustion operation of the first target stove burner 5 has started) is repeated until the determination result becomes affirmative. The first target stove burner 5 corresponds to the first target heating unit in the present invention.

Here, when the user presses the operation button 11 corresponding to the first target stove burner 5, the control device 20 supplies ignition control processing (fuel is supplied to the first target stove burner 5 while operating the ignition device). Control processing) is executed, thereby igniting the first target stove burner 5. Correspondingly, the judgment result of STEP2 becomes affirmative.

When the determination result of STEP 2 becomes affirmative, the control device 20 then sets the cooked object placed on the trivet 6 at the location of the first target stove burner 5 based on the image captured by the camera 31 in STEP 3. Acquires the food to be cooked information as the feature information of. More specifically, the control device 20 acquires a captured image from the camera 31, and identifies an image of the object to be cooked above the first target stove burner 5 from the captured image. Then, the control device 20 acquires, for example, external shape information indicating the outer shape and size of the cooking container of the cooking object as the cooking object information from the image of the cooking object.

The information to be cooked may include information indicating the shape and size of the handle of the cooking container or the handle of the lid of the cooking container. Further, when the image captured by the camera 31 is a color image, the color information of the cooking container and its lid may be included in the cooking object information. Further, the food to be cooked information may be, for example, a contour image of the outer shape of the food to be cooked.

Next, in STEP 4, the control device 20 determines whether or not the storage unit 20a already has the information to be cooked stored in the storage unit 20a. Here, immediately after the start of the automatic cooking operation, the food to be cooked information is not yet stored in the storage unit 20a, and the determination result of STEP 4 becomes negative. In this case, the control device 20 then stores the food to be cooked information acquired in STEP 3 in the storage unit 20a in STEP 5, and also performs a substantial automatic cooking operation (of the thermal power of the first target stove burner 5). (Operation that automatically controls the change over time in a manner corresponding to the menu of automatic cooking) is started.

Next, in STEP 8, the control device 20 performs a predetermined operation (operation on the stove operation panel 13 or operation on a communication terminal capable of communicating with the control device 20) for forcibly ending the automatic cooking operation currently being executed. ) Was done by the user.

If the determination result of STEP 8 is negative, the control device 20 performs a fire extinguishing operation of the first target stove burner 5 (pressing operation of the operation button 11 corresponding to the first target stove burner 5) in STEP 9. Whether or not it is determined is determined based on the operation signal of the operation button 11. Then, when the determination result of STEP 9 is negative, the control device 20 further performs an operation in STEP 10 in which the place where the object to be cooked is placed for the automatic cooking operation heats the object to be cooked. It is determined based on the detection signal of the object to be cooked detection sensor 22 whether or not the location on the first target stove burner 5 that has been changed has been changed to the location on another stove burner 5.

In this STEP 10, more specifically, in the control device 20, the food to be cooked is removed from the place on the first target stove burner 5, and the food to be cooked is newly placed on the place on the other stove burner 5. It is determined based on the detection signal of the object to be cooked detection sensor 22 whether or not the event of "burning" has occurred.

Here, the stove burner 5 used for the automatic cooking operation is changed from the first target stove burner 5 currently in use to a stove burner 5 that makes cooking work easier, or a stove with a larger maximum heating power. Automatic cooking due to a user's request such as changing to a burner 5, changing to a stove burner 5 with a smaller maximum heating power, or using the first target stove burner 5 in use for another cooking. In the middle of operation, the user may change (transfer) the place where the object to be cooked is placed on the first target stove burner 5 currently in use to a place on another stove burner 5.

Then, when performing this transfer, in many cases, the user performs a fire extinguishing operation on the first target stove burner 5, and then places a place to place the food to be cooked on another stove burner 5. Transfer. However, after transferring the place where the food to be cooked is placed, the fire extinguishing operation of the first target stove burner 5 used in the automatic cooking operation is performed, or the place where the food to be cooked is placed is changed. In some cases, another object to be cooked is placed on the first target stove burner 5 while the combustion operation of the first target stove burner 5 used in the automatic cooking operation is continued. possible.

Therefore, when the place where the object to be cooked is placed is changed by the automatic cooking operation, the judgment result of STEP 9 or STEP 10 becomes affirmative. In the present embodiment, the event that the determination result of STEP 9 or 10 becomes affirmative corresponds to the event that can occur due to the change of the place where the object to be cooked is placed.

Supplementally, the user is in the middle of the automatic cooking operation due to insufficient preparation of cooking ingredients and seasonings, or a sudden occurrence of a request such as a telephone call or a visitor. 1 In order to temporarily suspend the combustion operation of the target stove burner 5, the first target stove burner 5 may be extinguished. In such a case, the determination result of STEP 9 becomes affirmative even if the object to be cooked is not transferred.

If the judgment results of both STEPs 9 and 10 are negative, the combustion operation of the first target stove burner 5 is continuing, and the place where the object to be cooked is placed has not been relocated. Is. In this case, the control device 20 continues the automatic cooking operation in STEP 12, and further determines in STEP 13 whether or not the cooking by the automatic cooking operation is completed. Then, when the determination result of STEP 13 is negative, the control device 20 repeats the process from STEP 8.

Further, when the cooking by the automatic cooking operation is completed and the determination result of STEP 13 becomes affirmative, or when the user performs an operation to end the automatic cooking operation, the determination result of STEP 8 becomes affirmative. In this case, the control device 20 then erases the cooking object information and the cooking progress information stored in the storage unit 20a in STEP 17, and ends the automatic cooking operation. The cooking progress information is information stored in the storage unit 20a in STEP 11 described below.

When the determination result of any of STEPs 9 and 10 becomes affirmative, the cooking progress information is stored in the storage unit 20a in STEP11. The cooking progress information is information indicating to what step the automatic cooking operation has progressed when the determination result of STEP 9 or 10 becomes affirmative (information indicating the progress status of the automatic cooking operation). For example, the cooking progress information is information such as how many minutes the stew process has been executed in the entire process of the automatic cooking operation. Further, in the present embodiment, the cooking progress information includes the temperature detected by the temperature sensor 21 (the temperature sensor 21 at the location of the first target stove burner 5) when the determination result of STEP 9 or 10 becomes affirmative. (Temperature of cooking container) Contains temperature information to indicate.

Next, the control device 20 is ignited by the stove burner 5 on which the food to be cooked is placed (the stove burner 5 on which the food to be cooked is detected by the food to be cooked detection sensor 22) in STEP2. The process of determining whether or not the operation has been performed is executed in the same manner as in the case of the determination process of STEP 2 immediately after the start of the automatic cooking operation.

Here, when the determination result of STEP 9 or 10 becomes affirmative, the cooking of the object to be cooked by the automatic cooking operation has not been completed yet, so that the user can then complete the cooking of the object to be cooked. , The stove burner 5 at the place where the object to be cooked is placed is ignited. At this time, the judgment result of STEP2 becomes affirmative. Hereinafter, the newly ignited stove burner 5 after the determination result of STEP 9 or 10 becomes affirmative will be referred to as a second target stove burner 5. The second target stove burner 5 corresponds to the second target heating unit in the present invention.

In the present embodiment, in the situation where the determination result of STEP 9 is affirmative, as described above, when the object to be cooked is not transferred (the combustion operation of the first target stove burner 5 is temporarily performed). If you stop it). Therefore, the second target stove burner 5 is not always different from the first target stove burner 5, and may be the same.

When the determination result of STEP 2 becomes affirmative by igniting the second target stove burner 5, the control device 20 then sets the cooked food information (the cooked food on the second target stove burner 5) in STEP 3. The process of acquiring the food to be cooked information) is executed in the same manner as the process of STEP 3 immediately after the start of the automatic cooking operation, and further, the determination process of STEP 4 described above is executed.

In this case, in STEP 5 immediately after the start of the automatic cooking operation, the object to be cooked information is already stored in the storage unit 20a, so that the determination result in STEP 4 becomes positive. In this case, the control device 20 then determines in STEP 6 whether or not the cooked food information newly acquired in STEP 3 matches the cooked food information stored in the storage unit 20a. In other words, this determination process is a process of determining whether or not the object to be cooked heated on the first target stove burner 5 and the object to be cooked heated on the second target stove burner 5 are the same. Is.

If the determination result of STEP 6 becomes affirmative, the object to be cooked by the automatic cooking operation using the first target stove burner 5 immediately before STEP 9 or 10 changes to the second target stove burner 5. It can be considered to be the same as the cooked object that was used and started cooking. In this case, the control device 20 then sets the remaining automatic cooking operation (STEP 9 or 10) in STEP 7 based on the cooking progress information stored in the storage unit 20a (cooking progress information stored in STEP 11). The automatic cooking operation that should be executed after the time when the judgment result becomes affirmative) is restarted in the second target stove burner 5.

In this case, the control device 20 reflects the temperature indicated by the temperature information in the cooking progress information (the detected temperature when the determination result of STEP 9 or 10 becomes affirmative), and the second target stove The change in the combustion amount (calorific value) of the burner 5 is controlled. Specifically, the control device 20 raises the temperature detected by the temperature sensor 21 at the location of the second target stove burner 5 to the temperature indicated by the temperature information in the cooking progress information. After the combustion operation of the above is performed, the remaining automatic cooking operation is executed by the second target stove burner 5. After that, the control device 20 re-executes the process from STEP 8 described above.

On the other hand, after the start of the automatic cooking operation, before the judgment result of STEP 9 or 10 becomes affirmative, due to a change in the amount of cooking utensils put into the cooking container of the object to be cooked, etc., STEP 9 or 10 After the judgment result becomes affirmative, or when changing the placement location of the cooking container of the object to be cooked, the user decides the cooking container to put the cooking ingredients in the original cooking container (judgment of STEP 9 or 10). The cooking container of the object to be cooked just before the result becomes positive) may be changed to another cooking container. In such a case, the determination result of STEP 6 becomes negative. Further, even if the cooking container of the object to be cooked immediately before the determination result of STEP 9 or 10 becomes affirmative and the cooking container of the object to be cooked which has started heating by the second target stove burner 5 are the same, the cooking is performed. The judgment result of STEP 6 may be negative due to the displacement of the lid of the container or the like.

When the determination result of STEP 6 becomes negative in this way, the control device 20 then displays on the display unit of the stove operation panel 13 whether or not to continue the automatic cooking operation in STEP 14. Inquire the user by voice guidance or the like. Further, in STEP 15, the control device 20 determines by the user a predetermined operation (operation on the stove operation panel 13 or operation on a communication terminal capable of communicating with the control device 20) for continuing the automatic cooking operation. Determine if it was done in time.

Then, when the determination result of STEP 15 becomes affirmative, the user wants to continue the automatic cooking operation. Therefore, the control device 20 newly stores the food to be cooked information in STEP 16 in the storage unit 20a. Then, the process from STEP 7 described above is executed. As a result, the remaining automatic cooking operation is restarted. In this case, since the cooking container may be different from the cooking container heated by the first target stove burner 5, the automatic cooking operation may be restarted regardless of the temperature information of the cooking progress information. ..

When the determination result of STEP 15 becomes negative, the control device 20 erases the cooking object information and the cooking progress information stored in the storage unit 20a in the above-mentioned STEP 17, and automatically cooks. End the operation.

In the present embodiment, the control process of the control device 20 related to the automatic cooking operation is executed as described above. Supplementally, in the embodiments described above, the treatments of STEP3 and 5 correspond to the first treatment in the present invention, the treatments of STEP9, 10 and 11 correspond to the second treatment in the present invention, and the treatment of STEP6 corresponds to the present invention. Corresponds to the third process in the above, and the process of STEP 7 corresponds to the fourth process in the present invention.

According to the present embodiment described above, in order to change the stove burner 5 to be used during the execution of the automatic cooking operation, the place where the object to be cooked is placed is changed from the place on the first target stove burner 5 to the second target. Even if it is moved to a place on the stove burner 5, the automatic cooking operation can be continued. In this case, it is a necessary condition that in STEP 6, it is determined that the object to be cooked on the second target stove burner 5 is the same as the object to be cooked on the first target stove burner 5. Since the automatic cooking operation is automatically continued, it is possible to prevent the automatic cooking operation from being continued for the object to be cooked different from the object to be cooked heated on the first target stove burner 5.

Further, since the determination process of STEP 6 is performed based on the cooking object information including the external shape information of the cooking object, the automatic cooking operation can be executed as described above by using various general-purpose cooking containers. .. Therefore, it is possible to provide a highly convenient cooking cooker 2.

Further, since the food to be cooked information as the characteristic information of the food to be cooked can be easily obtained from the captured image of one camera 31 installed above the cooking cooker 2, the cooking system 1 including the camera 31 can be easily obtained. It can be simple and inexpensive.

Further, in the present embodiment, the first target stove burner 5 is used not only when the place where the object to be cooked is placed is moved but also when the combustion operation of the first target stove burner 5 is temporarily stopped. If it is ignited again, the automatic cooking operation can be automatically continued. Further, even if the cooking container in which the food to be cooked is put is changed during the automatic cooking operation, the automatic cooking operation can be continued by the user performing a predetermined automatic cooking continuation operation. Therefore, the convenience of the cooking cooker 2 can be enhanced.

In the embodiment described above, the gas stove is illustrated as the heating cooker 2, but the heating cooker in the present invention may be, for example, an IH heater or a heating cooker having an electric heater as a heating unit. Further, in the above-described embodiment, in order to acquire the feature information of the object to be cooked, the image taken by the camera 31 (photographing device) is used, for example, a distance measuring sensor that measures the distance to various places on the outer surface of the cooking container. It is also possible to acquire the characteristic information of the object to be cooked by using the distance measurement data. Alternatively, the feature information of the object to be cooked may be acquired by using both the distance measuring sensor and the image captured by the camera. Further, a camera may be provided for each heating unit. Further, the camera is not limited to one capable of acquiring a visible light image, and may be one capable of acquiring an infrared image.

Further, in the above embodiment, when the determination result of STEP 6 is negative, the processes of STEP 14 and 15 are executed, but for example, the automatic cooking operation is performed through the process of STEP 17 without executing the processes of STEP 14 and 15. You may end it.
