JP-A-2015-72802 Japanese Unexamined Patent Publication No. 2012-22905

However, in the heating cooker of Patent Document 1, in order to change the heating output of cooking data, an application of an external terminal must be operated before the automatic cooking operation, and heating is performed during the automatic cooking operation. There is a problem that the output cannot be changed.

Further, in the heating cooker of Patent Document 2, if the user operates the heating power setting means during the execution of the automatic cooking operation, the automatic cooking operation is stopped and the user manually continues cooking. Therefore, if the user changes the heating output excessively, the intended cooking cannot be performed, and the quality of the cooked product tends to vary. Furthermore, once the automatic cooking operation is stopped, even if the user manually adjusts the heating output appropriately to complete a good-quality cooked product, and then tries to reproduce the same thing, the automatic cooking operation is performed. It is difficult to reproduce because the user's previous memory is the only source for the user to manually change the heating output as well after the discontinuation.

INDUSTRIAL APPLICABILITY The present invention has been made in view of the above-mentioned conventional circumstances, and provides a cooking cooker capable of suppressing variations in the quality of cooked foods while enabling changes in the heating output during execution of an automatic cooking operation. Is an issue to be solved.

The heating cooker of the present invention has a heating means for heating an object to be heated and a heating means.
A control means for controlling the heating output of the heating means and
The input means for receiving the input operation for changing the heating output is provided.
The control means is a cooking device capable of performing an automatic cooking operation that controls at least the heating output based on a preset cooking sequence.
In the cooking sequence, an execution value of the heating output and a change range determined by at least one of the upper limit value and the lower limit value of the heating output are defined.
The control means is configured to change the heating output within the change range when the input means receives the input operation during the execution of the automatic cooking operation.

In the cooking apparatus of the present invention, when the user changes the heating output during the execution of the automatic cooking operation, the change is determined by at least one of the upper limit value and the lower limit value of the heating output by performing an input operation to the input means. The heating output can be changed within the range, and there is no need to stop the automatic cooking operation.

Further, in this cooking device, the change of the heating output during the execution of the automatic cooking operation is restricted within the change range, so that it is possible to prevent the user from excessively changing the heating output, so that the intended cooking can be performed. Easy to do.

Furthermore, once the user changes the heating output during the automatic cooking operation to complete a good-quality cooked product, and then tries to reproduce the same, the user not only remembers the last time. , It is easy to reproduce because it can be relied on to suppress excessive changes by limiting the range of changes.

Therefore, in the cooking device of the present invention, it is possible to change the heating output during the execution of the automatic cooking operation, and it is possible to suppress the variation in the quality of the cooked product.

It is desirable that the cooking sequence has a plurality of cooking steps, each of which has a defined execution value and a range of change.

In this case, the cooking sequence can suitably set a plurality of cooking steps including initial heating, high temperature cooking, low temperature cooking, finishing, and the like, depending on the menu. Here, when the execution value of the heating output in the cooking step is large, if the heating output is changed so as to be excessively increased from the execution value, it tends to cause overheating such as charring. Further, when the execution value of the heating output in the cooking step is small, if the heating output is changed so as to be excessively reduced from the execution value, it tends to cause insufficient heating such as burning. In this respect, the above configuration makes it possible to finely change the heating output according to the cooking purpose of each cooking step. As a result, overheating and underheating can be suppressed, and variations in the quality of cooked products can be further suppressed.

It is desirable that the cooking cooker of the present invention further includes a notification means for performing notification. Then, when an input operation for changing the heating output beyond the change range is performed on the input means, the control means may control the notification means to notify that the change range is out of the range. desirable.

In this case, it can be easily recognized that the user has performed an input operation that exceeds the change range. As a result, the user can reduce the degree of change and redo the input operation, which improves convenience.

It is desirable that the cooker of the present invention further comprises a storage means for storing a cooking sequence. Then, at the end of the automatic cooking operation, the control means determines whether or not there is a change history in which the heating output is changed in the executed cooking sequence, and if it is determined that there is a change history, the cooking corresponding to the change history is performed. It is desirable to receive a selection input as to whether or not to store the sequence in the storage means.

In this case, the user may select whether or not to store the cooking sequence corresponding to the change history in the storage means only when there is a change history of the heating output. Therefore, the complexity of the user's judgment can be suppressed, and the convenience is improved. In addition, once the user changes the heating output during the automatic cooking operation to complete a good-quality cooked product, and then tries to reproduce the same, the user relies on the previous memory. It can be easily reproduced by using the stored cooking sequence.

When the cooking sequence corresponding to the change history is stored in the storage means, it is desirable that the control means separately stores the change history before and after the occurrence.

In this case, when the cooking sequence corresponding to the change history is stored in the storage means, the change in the heating output made by the user in the middle of the cooking sequence can be preferably reflected. As a result, when the cooking sequence corresponding to the change history is read from the storage means and executed again, it is possible to further suppress the variation in the quality of the cooked product.

According to the cooking device of the present invention, it is possible to change the heating output during the execution of the automatic cooking operation, and it is possible to suppress the variation in the quality of the cooked product.

<Operation unit>
The operation unit 30 has a power switch 33 for switching the power of the cooking cooker 1 on and off. The power switch 33 is arranged in the upper right portion of the region located to the right of the grill door 17M on the front panel 8P.

Further, the operation unit 30 has three operation dials 31 for operating ignition, fire extinguishing, and heating output adjustment for each of the left and right gas burners 11 and the heating chamber 17. The operation dial 31 is an example of the "input means" of the present invention.

The two operation dials 31 for the left and right gas burners 11 are arranged in an area located to the right of the grill door 17M on the front panel 8P. One operation dial 31 for the heating chamber 17 is arranged in an area located to the left of the grill door 17M in the front panel 8P.

When the user performs an ignition operation by pushing an arbitrary operation dial 31, the information is transmitted from the operation unit 30 to the control means 20. Then, the control means 20 controls the combustion unit 10 to ignite the gas burner 11 or the heating chamber 17 corresponding to the operation dial 31.

When the user stops pushing the operation dial 31 after performing the ignition operation, the operation dial 31 protrudes forward from the front panel 8P.

When the operation dial 31 is rotated clockwise at a rotation angle corresponding to the increase amount of the heating output desired by the user while the operation dial 31 is projected, the information is transmitted from the operation unit 30 to the control means. It is transmitted to 20. Then, the control means 20 controls the combustion unit 10 to increase the heating output of the gas burner 11 or the heating chamber 17 corresponding to the operation dial 31.

Is transmitted to the control means 20. Then, the control means 20 controls the combustion unit 10 to reduce the heating output of the gas burner 11 or the heating chamber 17 corresponding to the operation dial 31.

Then, when the user performs a fire extinguishing operation of pushing the operation dial 31 in a protruding state to the original position, the information is transmitted from the operation unit 30 to the control means 20. Then, the control means 20 controls the combustion unit 10 to extinguish the gas burner 11 or the heating chamber 17 corresponding to the operation dial 31.

The heating output increasing operation and the heating output decreasing operation for the operation dial 31 are examples of the "input operation for changing the heating output" of the present invention. In this embodiment, as will be described later, when the heating output increasing operation or the heating output decreasing operation is performed during the execution of the automatic cooking operation, the control means 20 conditionally changes the heating output.

Further, the operation unit 30 has operation buttons 32A, 32B, 32C for performing various settings and selection inputs. The operation unit 30 is arranged in the lower right portion of the region located to the right of the grill door 17M on the front panel 8P.

For example, when executing an automatic cooking operation for a menu desired by the user, the operation buttons 32A to 32C are operated to select one desired from a plurality of menus and instruct the execution of the automatic cooking operation. Further, as will be described later, the operation buttons 32A to 32C receive a selection input as to whether or not to store the cooking sequence corresponding to the change history in the storage means 21 at the end of the automatic cooking operation.

<Notification means>
As shown in FIGS. 1 and 2, the notification means 40 has a display unit 41 and a sounding unit 42. The display unit 41 and the sounding unit 42 are arranged side by side with the operation buttons 32A to 32C in the lower right portion of the region located to the right of the grill door 17M on the front panel 8P.

The display unit 41 notifies the user of the operating state of the gas burner 11 and the heating chamber 17, the error state, various setting information, and the like by displaying character messages and the like. The sounding unit 42 notifies the user of the operating state of the gas burner 11 and the heating chamber 17, the error state, various setting information, etc. by voice message, buzzer sound, melody sound, or the like.

<Automatic cooking operation>
When the user operates the operation buttons 32A to 32C to select a desired one from a plurality of menus and instruct the execution of the automatic cooking operation, the control means 20 indicates the automatic cooking operation shown in FIGS. 3 and 4. The program is executed, and an automatic cooking operation for controlling the heating output, the required time, etc. is executed based on a preset cooking sequence.

In this embodiment, a case where the automatic cooking operation is executed using the gas burner 11 will be described. Since the same applies to the case where the automatic cooking operation is executed using the heating chamber 17, the description thereof will be omitted.

The cooking sequence has a plurality of cooking steps consisting of initial heating, high temperature cooking, low temperature cooking, finishing, etc., depending on the menu. Then, in each cooking step, an execution value of the heating output and a change range determined by at least one of the upper limit value and the lower limit value of the heating output are defined.

In this embodiment, a case where the automatic cooking operation of the selected menu is executed based on the cooking sequence shown in FIG. 5 will be described. The cooking sequence shown in FIG. 5 is simplified by setting the number of cooking steps to three for the sake of simplification of the explanation.

In the first (i = 1) cooking step of the cooking sequence shown in FIG. 5, the execution value E1 (= 5) of the heating output, the upper limit value U1 (= 7) and the lower limit value L1 (= 3) of the heating output are set. The change range C1 determined by is defined.

In the second (i = 2) cooking step of the cooking sequence shown in FIG. 5, the execution value E2 (= 10) of the heating output, the upper limit value U2 (= 11) of the heating output, and the lower limit value L2 (= 7. The change range C2 determined by 5) is defined.

In the third (i = 3) cooking step of the cooking sequence shown in FIG. 5, the execution value E3 (= 3) of the heating output, the upper limit value U3 (= 4) and the lower limit value L3 (= 2) of the heating output are set. The change range C3 determined by is specified.

When the control means 20 starts the automatic cooking operation program shown in FIGS. 3 and 4, the control means 20 first acquires information on the selected cooking sequence from the storage means 21 in step S101 shown in FIG.

In this embodiment, the control means 20 has the time required for the three cooking steps, the execution values E1, E2, E3 of each cooking step, and the change ranges C1, C2, C3 (upper limit value U1) for the cooking sequence shown in FIG. , U2, U3, lower limit values L1, L2, L3) and the like are acquired.

Next, the control means 20 shifts to step S102 and sets i = 1 for the counter variable i in the cooking step.

Next, the control means 20 proceeds to step S103, controls the combustion unit 10, ignites the gas burner 11, and starts the cooking sequence shown in FIG.

Next, the control means 20 proceeds to step S104, and acquires information such as a required time, an execution value E1, and a change range C1 (upper limit value U1, lower limit value L1) for the i (= 1) th cooking step.

Next, the control means 20 proceeds to step S105, and controls the combustion unit 10 so that the heating output of the gas burner 11 becomes the execution value E1.

Next, the control means 20 proceeds to step S106, and starts timing the required time for the i (= 1) th cooking step.

Next, the control means 20 proceeds to step S111, and determines whether or not the heating output increasing operation and the heating output decreasing operation for the operation dial 31 have been performed. If "No" in step S111, the process proceeds to step S112. On the other hand, in the case of "Yes" in step S111, the process proceeds to step S113.

After shifting from step S111 to step S112, the control means 20 determines whether or not the required time has elapsed. If "No" in step S112, the process returns to step S111. On the other hand, in the case of "Yes" in step S112, the process proceeds to step S116.

When shifting from step S111 to step S113, the control means 20 determines whether or not the heating output increasing operation or the heating output decreasing operation exceeds the change range.

If "No" in step S113, the process proceeds to step S114. Then, the control means 20 changes the heating output within the change range according to the heating output increasing operation or the heating output decreasing operation, and then returns to step S111.

For example, when the heating output increasing operation for increasing the heating output by "1" from the execution value E1 (= 5) is performed at the timing T1 shown in FIG. 5 while the first cooking step is being executed, the heating output increasing operation is performed. The upper limit value U1 (= 7) of the change range C1 is not exceeded. Therefore, the control means 20 changes the heating output from the execution value E1 (= 5) to “6” as shown by the alternate long and short dash line in FIG.

On the other hand, in the case of "Yes" in step S113, the process proceeds to step S115. Then, the control means 20 notifies that the heating output increasing operation or the heating output decreasing operation is out of the change range, and then returns to step S111.

For example, if the heating output increasing operation or the heating output decreasing operation exceeds the change range C1 (upper limit value U1, lower limit value L1) while the first cooking step is being executed, “Yes” is set in step S113, and step S115. Move to. Then, the control means 20 controls the notification means 40 to display a character message or an error code indicating that the heating output increasing operation or the heating output decreasing operation is out of the change range on the display unit 41, or the notification means 40 may display a character message or an error code. A voice message or a warning sound to that effect is emitted from the sounding unit 42. As a result, the user can reduce the degree of change and redo the heating output increasing operation or the heating output decreasing operation.

If the process goes back from step S112 to step S116, it means that the i-th cooking step is completed. The control means 20 determines in step S116 whether or not there is a next cooking step.

If there is a next cooking step, the result is "No" in step S116, and the process proceeds to step S117. In the cooking sequence shown in FIG. 5, when the first and second cooking steps are completed, the result is "No" in step S116. Then, the control means 20 adds "1" to the counter variable i in step S117, and then returns to step S104 to execute the next cooking step.

On the other hand, if there is no next cooking step, it becomes "Yes" in step S116 and the process proceeds to step S118. In the cooking sequence shown in FIG. 5, when the third cooking step is completed, the result is “Yes” in step S116. Then, the control means 20 controls the combustion unit 10 in step S118 to extinguish the gas burner 11, ends the cooking sequence shown in FIG. 5, and then proceeds to step S121 shown in FIG.

Although the description is simplified, the control means 20 changes the range C2 (upper limit value U2, lower limit value L2) by steps S111, S113, and S114 during the execution of the second cooking step of the cooking sequence shown in FIG. The heating output of the gas burner 11 is changed within the change range C2 according to the operation of increasing the heating output or the operation of decreasing the heating output. Further, the control means 20 increases the heating output without exceeding the change range C3 (upper limit value U3, lower limit value L3) by steps S111, S113, and S114 during the execution of the third cooking step of the cooking sequence shown in FIG. The heating output of the gas burner 11 is changed within the change range C3 according to the operation or the operation of reducing the heating output.

When shifting from step S118 shown in FIG. 3 to step S121 shown in FIG. 4, the control means 20 determines whether or not there is a change history of the heating output in the executed cooking sequence. If "No" in step S121, the automatic cooking operation program is terminated. On the other hand, in the case of "Yes" in step S121, the process proceeds to step S122. In this embodiment, since the change history is generated at the timing T1 during the execution of the first cooking step of the cooking sequence shown in FIG. 5, the result is “Yes” in step S121.

When the process proceeds from step S121 to step S122, the control means 20 controls the notification means 40 to execute notification for the user to select whether or not to store the cooking sequence corresponding to the change history in the storage means 21. Specifically, a character message for letting the user make the selection is displayed on the display unit 41, or a voice message to that effect is pronounced from the sounding unit 42.

Next, the control means 20 proceeds to step S123 and determines whether or not the storage of the cooking sequence corresponding to the change history is selected. When the user operates the operation buttons 32A to 32C to input without selecting the storage of the cooking sequence corresponding to the change history, the result is "No" in step S123, and the automatic cooking operation program is terminated. On the other hand, when the user operates the operation buttons 32A to 32C to perform selection input for storing the cooking sequence corresponding to the change history in the storage means 21, the result is “Yes” in step S123, and the process proceeds to step S124.

When the process proceeds to step S124, the control means 20 divides the cooking sequence corresponding to the change history into before and after the change history and stores it in the storage means 21.

As a specific example, in the cooking sequence shown in FIG. 5, the change history is generated at the timing T1 during the execution of the first cooking step. As shown in FIG. 7, the cooking sequence corresponding to this change history is divided into before the timing T1 where the change history occurs and after the timing T1, and the number of cooking steps is increased to four and then stored. It is stored in the means 21.

The execution value E1A and the change range C1A (upper limit value U1A, lower limit value L1A) of the first cooking step of the cooking sequence shown in FIG. 7 are the execution value E1 and the change range of the first cooking step of the cooking sequence shown in FIG. It is the same as C1 (upper limit value U1, lower limit value L1).

The execution value E2A of the second cooking step of the cooking sequence shown in FIG. 7 is the heating output changed at the timing T1 of the cooking sequence shown in FIG. On the other hand, the change range C2A (upper limit value U2A, lower limit value L2A) of the second cooking step of the cooking sequence shown in FIG. 7 is the change range C1 (upper limit value U1) of the first cooking step of the cooking sequence shown in FIG. , The lower limit value L1).

The sum of the time required for the first cooking step and the time required for the second cooking step in the cooking sequence shown in FIG. 7 is the same as the time required for the first cooking step in the cooking sequence shown in FIG.

The time required for the third cooking step of the cooking sequence shown in FIG. 7, the execution value E3A and the change range C3A (upper limit value U3A, lower limit value L3A) are the time required for the second cooking step of the cooking sequence shown in FIG. It is the same as the execution value E2 and the change range C2 (upper limit value U2, lower limit value L2).

The time required for the fourth cooking step of the cooking sequence shown in FIG. 7, the execution value E4A and the change range C4A (upper limit value U4A, lower limit value L4A) are the time required for the third cooking step of the cooking sequence shown in FIG. It is the same as the execution value E3 and the change range C3 (upper limit value U3, lower limit value L3).

Then, when the control means 20 finishes step S124, the control means 20 ends the automatic cooking operation program.

<Action effect>
The operation and effect of the cooking device 1 of the embodiment will be described by exemplifying a case where the user executes an automatic cooking operation based on the cooking sequence shown in FIG. Even if the cooking sequence is different from the cooking sequence shown in FIG. 5, as long as the cooking sequence defines the execution value of the heating output and the change range determined by at least one of the upper limit value and the lower limit value of the heating output. The effects are similar.

In the cooking device 1 of the embodiment, when the user changes the heating output during the execution of the automatic cooking operation based on the cooking sequence shown in FIG. 5, the operation dial 31 is operated to increase the heating output or decrease the heating output. conduct.

Here, if the first cooking step is being executed, the heating output can be changed within the change range C1 determined by the upper limit value U1 and the lower limit value L1 of the heating output in steps S111, S113, and S114 shown in FIG. be. Similarly, while the second cooking step is being executed, the heating output can be changed within the change range C2 (upper limit value U2, lower limit value L2). While the third cooking step is being executed, the heating output can be changed within the change range C3 (upper limit value U3, lower limit value L3). As a result, in this cooking cooker 1, it is not necessary to stop the automatic cooking operation in order to change the heating output.

Further, in the cooking cooker 1, the change of the heating output during the execution of the automatic cooking operation is limited to the change range C1 in the first cooking step, and is limited to the change range C2 in the second cooking step. The second cooking step is restricted to the change range C3. This makes it possible to prevent the user from excessively changing the heating output in each cooking step. As a result, in this cooking cooker 1, it is easy to perform the intended cooking by the automatic cooking operation.

Furthermore, once the user changes the heating output during the automatic cooking operation to complete a good-quality cooked product, and then tries to reproduce the same, the user not only remembers the last time. , It is easy to reproduce because it can be relied on to suppress excessive changes due to the restrictions of the change ranges C1, C2, and C3.

Therefore, in the cooking device 1 of the embodiment, it is possible to change the heating output during the execution of the automatic cooking operation, and it is possible to suppress variations in the quality of the cooked product.

Further, in the cooking device 1, since the cooking sequence has a plurality of cooking steps, a plurality of cooking steps including initial heating, high temperature cooking, low temperature cooking, finishing, etc. can be suitably set according to the menu. .. Then, as in the execution values E1, E2, E3 and the change range C1, C2, C3 of the cooking sequence shown in FIG. 5, the execution value and the change range are defined for each cooking step. Here, since the execution value E2 (= 10) of the heating output in the second cooking step of the cooking sequence shown in FIG. 5 is large, if the heating output is changed so as to be excessively increased from the execution value E2, it is burnt or the like. It is easy to cause overheating. Further, since the execution value E3 (= 3) of the heating output in the third cooking step is small, if the heating output is changed so as to be excessively reduced from the execution value E3, it is likely to cause insufficient heating such as burning. .. In this respect, with the above configuration, the heating output can be finely changed according to the cooking purpose of each cooking step. As a result, in this cooking device 1, it is possible to suppress overheating and insufficient heating, and it is possible to further suppress variations in the quality of the cooked product.

Further, in the cooking device 1, the control means 20 attempts to change the heating output beyond the change range C1 in the first cooking step in steps S111 and S113 shown in FIG. When it is determined that the reduction operation has been performed on the operation dial 31, the process proceeds to step S115, and the notification means 40 is controlled to notify the display unit 41 and the sounding unit 42 that the change range C1 is out of range. With this configuration, the user can easily recognize that the heating output increasing operation or the heating output decreasing operation exceeding the change range C1 has been performed. The same applies to the case where the heating output is to be changed beyond the change range C2 in the second cooking step and the case where the heating output is to be changed beyond the change range C3 in the third cooking step. As a result, the user can reduce the degree of change and redo the heating output increasing operation or the heating output decreasing operation, which improves convenience.

Further, in the cooking cooker 1, the control means 20 determines in step S121 shown in FIG. 4 whether or not there is a change history in which the heating output is changed in the executed cooking sequence at the end of the automatic cooking operation. .. Then, when the control means 20 determines that there is a change history, the control means 20 proceeds to steps S122 and 123, and notifies the user whether or not to store the cooking sequence corresponding to the change history in the storage means 21. Execute and receive selection input from the user. With this configuration, the user may select whether or not to store the cooking sequence corresponding to the change history in the storage means 21 only when there is a change history of the heating output. Therefore, the complexity of the user's judgment can be suppressed, and the convenience is improved. In addition, once the user changes the heating output during the automatic cooking operation to complete a good-quality cooked product, and then tries to reproduce the same, the user relies on the previous memory. It can be easily reproduced by using the stored cooking sequence.

Further, in the heating cooker 1, when the control means 20 stores the cooking sequence corresponding to the change history in the storage means 21 in step S124 shown in FIG. 4, the control means 20 is divided into before and after the change history is generated. And memorize it. Specifically, when a change history occurs at timing T1 in the cooking sequence shown in FIG. 5, as shown in FIG. 7, the cooking sequence corresponding to the change history is divided into before timing T1 and after timing T1. Then, after the number of cooking steps is increased to 4, it is stored in the storage means 21. With this configuration, when the cooking sequence corresponding to the change history is stored in the storage means 21, the change in the heating output made by the user in the middle of the cooking sequence can be suitably reflected. As a result, when the cooking sequence corresponding to the change history is read from the storage means 21 and executed again, the variation in the quality of the cooked product can be further suppressed.

Although the present invention has been described above with reference to the examples, it is needless to say that the present invention is not limited to the above-mentioned embodiments and can be appropriately modified and applied without departing from the spirit of the present invention.

In the embodiment, the storage means 21 built in the cooking device 1 stores a plurality of cooking sequences, but the present invention is not limited to this configuration. For example, the cooking cooker may use a cloud server or the like on the Internet as an external storage means, and a plurality of cooking sequences may be stored in the external storage means. Then, the control means may acquire the information of the selected cooking sequence from the external storage means when the automatic cooking operation is executed.

In the embodiment, the change range C1 of the cooking sequence is determined by the upper limit value U1 and the lower limit value L1 of the heating output, and the same applies to the change ranges C2 and C3, but the present invention is not limited to this configuration. For example, the change range of the cooking sequence may be determined only by the upper limit value of the heating output, or may be determined only by the lower limit value of the heating output.

In the embodiment, when the cooking sequence corresponding to the change history is stored in the storage means 21, the control means 20 separately stores the change history before and after the occurrence, but the present invention has this configuration. Not limited. For example, when the cooking sequence corresponding to the change history is stored in the storage means, the execution value of the heating output of the cooking step in which the change history has occurred is changed from the beginning of the cooking step to the value of the heating output after the change history. You may memorize it. Further, the control means 20 may be able to change the required time by receiving an operation input for changing the required time of an arbitrary cooking step during the automatic cooking operation. Then, when there is a history of changing the required time, the control means 20 may store the cooking sequence corresponding to the change history including the history in the storage means 21.
