The communication unit 13 is a communication interface that communicates with other devices.

For example, the communication unit 13 receives the detection information from the motion sensor 300. The detection information is information indicating the detection result of the motion sensor 300. The motion sensor 300 is, for example, a sensor that detects whether or not there is a user in the kitchen, such as an infrared sensor and a pressure sensor built in the kitchen mat. Although the motion sensor 300 is provided outside the terminal 100 as an example in FIG. 1, the motion sensor 300 may be provided inside the terminal 100.

In the present embodiment, the communication unit 13 receives either the first detection information indicating that the user is not in the kitchen or the second detection information indicating that the user is in the kitchen.

Further, for example, the communication unit 13 transmits the thermal power control information (details will be described later) generated by the control unit 14 to the cooking device 200.

The control unit 14 is a control device such as a processor.

For example, the control unit 14 reads the predetermined cooking process image information from the storage unit 12, and controls the output unit 11 so as to output the cooking process image based on the cooking process image information. By this control, the output unit 11 displays a predetermined cooking process image on the screen.

Further, for example, when the control unit 14 controls the output unit 11 so as to output a predetermined cooking process image, the control unit 14 obtains cooking condition information of the cooking process (that is, the cooking process being executed) shown in the cooking process image. Read from the storage unit 12.

Further, for example, the control unit 14 starts measuring the time when the first detection information is received by the communication unit 13.

Further, for example, when the first detection information is received by the communication unit 13, the control unit 14 determines whether or not the cooking process being executed is the heating process based on the cooking condition information read from the storage unit 12. Judgment (hereinafter referred to as the first judgment). For example, when the information indicating the cooking method included in the cooking condition information is any one of "simmering", "steaming", "stir-frying", "baking", and "fried", the control unit 14 is executing the cooking process. Is a heating process.

Further, for example, when the control unit 14 determines in the first determination that the cooking process being executed is the heating process, the communication unit 13 receives the second detection information within a certain time from the reception of the first detection information. It is determined whether or not the determination has been made (hereinafter referred to as a second determination). The fixed time here is, for example, 3 seconds.

Further, for example, when the control unit 14 determines in the second determination that the second detection information has not been received within a certain period of time, the control unit 14 generates the thermal power control information. For example, the control unit 14 reads out the control method information of FIG. 3 from the storage unit 12, and in the control method information, the control method associated with the heating method (boil, steam, fry, bake, fry) being executed. To identify. Then, the control unit 14 generates thermal power control information instructing the execution of the specified control method. Then, the control unit 14 controls the communication unit 13 so as to transmit the thermal power control information to the cooking device 200. As a result, the thermal power control information is transmitted to the cooking device 200.

Next, the configuration of the cooking device 200 will be described.

The cooking device 200 is, for example, an IH (Induction Heating) cooker or a microwave oven. The cooking device 200 includes an input unit 20, a functional unit 21, a storage unit 22, a communication unit 23, and a control unit 24.

The input unit 20 is an input device such as a button or a touch panel that accepts a user's operation.

For example, the input unit 20 accepts an operation instructing the function unit 21, which will be described later, to exert its function. For example, the input unit 20 accepts a temperature setting operation in the heating function of the functional unit 21.

The functional unit 21 is a device that changes the state of an object (for example, a cooking utensil such as a pan or a frying pan, or an ingredient), and is, for example, a heating device such as a heater.

For example, the functional unit 21 heats the cooking utensil by being controlled by the control unit 24 described later.

The storage unit 22 is a storage device such as a memory or a hard disk.

For example, the storage unit 22 stores the thermal power control information received by the communication unit 23, which will be described later.

The communication unit 23 is a communication interface that communicates with other devices.

For example, the communication unit 23 receives the thermal power control information transmitted from the terminal 100.

The control unit 24 is a control device such as a processor.

For example, when the thermal power control information is received by the communication unit 23, the control unit 24 stores the thermal power control information in the storage unit 22. Then, the control unit 24 reads the thermal power control information from the storage unit 22 at a predetermined timing, and controls the functional unit 21 based on the thermal power control information. For example, the control unit 24 causes the function unit 21 to execute the control method (any of the control methods shown in FIG. 3) shown in the thermal power control information.

The configuration of the thermal power control system according to the present embodiment has been described above.

Next, the operation of the thermal power control system according to the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing an example of the operation of the thermal power control system according to the present embodiment. In the following, as an example, a case where the user executes the second cooking step shown in FIG. 2 will be described.

First, the control unit 14 of the terminal 100 reads the cooking process image information corresponding to the second cooking process from the storage unit 12, and controls the output unit 11 so as to output the cooking process image based on the cooking process image information. (Step S11). By this control, the output unit 11 displays a cooking process image showing a specific example of the second cooking process on the screen. The user sees this screen display and executes the second cooking step in the cooking apparatus 200. As a result, the cooking apparatus 200 is heated over high heat.

Further, in step S11, the control unit 14 reads the cooking condition information of the second cooking step from the storage unit 12. For example, in the recipe information of FIG. 2, information indicating each of the cooking method "stir-fry", the required time "2 minutes", and the heating power "high heat" is read out as cooking condition information.

Here, when the motion sensor 300 detects that the user has left the kitchen and is not in the user kitchen, the communication unit 13 receives the first detection information from the motion sensor 300 (step S12).

Next, when the first detection information is received by the communication unit 13, the control unit 14 starts measuring the time and makes a first determination based on the cooking condition information read from the storage unit 12. That is, the control unit 14 determines whether or not the cooking process being executed is a heating process (step S13).

When it is determined in the first determination that the cooking step being executed is not a heating step (step S13: NO), the flow ends. On the other hand, when it is determined in the first determination that the cooking step being executed is the heating step (step S13: YES), the flow proceeds to step S14. Here, since the information indicating the cooking method included in the cooking condition information is "stir-fry", the control unit 14 determines that the second cooking step being executed is the heating step (step S13: YES). Therefore, the flow proceeds to step S14.

Next, the control unit 14 makes a second determination. That is, the control unit 14 determines whether or not the second detection information has been received by the communication unit 13 within a certain time (for example, 5 seconds) from the reception of the first detection information (step S14).

When the second detection information is received within a certain time in the second determination (step S14: YES), the flow ends. On the other hand, if the second detection information is not received within a certain time in the second determination (step S14: NO), the flow proceeds to step S15. Here, as an example, it is assumed that the motion sensor 300 cannot detect that the user is in the user kitchen because the user does not return to the kitchen within a certain period of time, and the communication unit 13 does not receive the second detection information (step S14). : NO). Therefore, the flow proceeds to step S15.

Next, the control unit 14 generates thermal power control information (step S15). For example, the control unit 14 reads out the control method information of FIG. 3 from the storage unit 12, and in the control method information, the control method “low heat” associated with the heating method “stir-fry” being executed is set, and after a certain period of time has elapsed. Identify "off". The fixed time here is, for example, 7 seconds. Next, the control unit 14 generates thermal power control information instructing the execution of the specified control method. Then, the control unit 14 controls the communication unit 13 so as to transmit the thermal power control information to the cooking device 200.

Next, the communication unit 13 transmits the thermal power control information to the cooking device 200 (step S16).

Next, the communication unit 23 of the cooking device 200 receives the thermal power control information from the terminal 100 (step S17).

Next, the control unit 24 stores the thermal power control information in the storage unit 22, reads the thermal power control information from the storage unit 22 at a predetermined timing, and controls the thermal power of the functional unit 21 based on the thermal power control information. (Step S18). For example, the control unit 14 changes the thermal power of the functional unit 21 from high heat to low heat, and turns off the fire after a certain period of time (for example, 7 seconds) has elapsed from the change.

As described above, according to the present embodiment, when the user leaves the kitchen, the heating power can be adjusted according to the heating method being executed.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. Hereinafter, a modified example of the embodiment of the present invention will be described.

<Modification example 1>
For example, the fixed time used in the second determination may be, for example, the required time defined as the cooking condition in the recipe information of FIG. A specific example of this will be described below.

For example, in step S11 of FIG. 4, the control unit 14 indicates that the cooking method (heating method) information included in the cooking condition information of the cooking process being executed read from the storage unit 12 is "boiled" or "steamed". In this case, the fixed time used in the second determination is set as the required time included in the cooking condition information. For example, when the cooking condition information of the third cooking step is read out, the required time "15 minutes" is used in the second determination.

As described above, according to this modification, in the case of a heating method in which heating is performed for a relatively long time, for example, "simmering" or "steaming", a predetermined control method (predetermined control method) for a predetermined required time. For example, it is possible to prevent the "low heat" control method shown in FIG. 3) from being performed so that cooking is not interrupted.

<Modification 2>
For example, when a predetermined heating step is executed and cooking is performed with a heating power different from the predetermined heating power in the cooking apparatus 200, the cooking equipment 200 may be controlled to change the heating power. A specific example of this will be described below.

For example, when a predetermined heating process is started by the user (for example, after displaying the cooking process image in step S11 of FIG. 4), the control unit 24 of the cooking equipment 200 is in a state of thermal power in the functional unit 21 (for example, high heat). , Medium heat, or low heat) is generated and transmitted to the terminal 100. When the communication unit 13 receives the thermal power status information, the control unit 14 has the thermal power indicated by the thermal power status information and the predetermined thermal power indicated by the thermal power information included in the cooking condition information read from the storage unit 12. Determine if they match. As a result of this determination, when the two thermal powers do not match, the control unit 14 generates thermal power control information instructing the change to the predetermined thermal power. Then, this thermal power control information is transmitted from the terminal 100 to the cooking device 200. When the communication unit 23 receives the thermal power control information, the control unit 24 of the cooking device 200 controls the thermal power of the functional unit 21 based on the thermal power control information. As a result, the thermal power in the functional unit 21 is changed to a predetermined thermal power.

As described above, according to this modification, even if the user mistakenly sets the heating power in the cooking apparatus 200, for example, the heating power can be changed to an appropriate heating power regardless of the user's operation.

<Modification example 3>
For example, when a user who has left the kitchen returns to the kitchen after transmitting the thermal power control information to the cooking device 200, the control to return to the original thermal power may be performed. A specific example of this will be described below.

For example, after the first detection information is received (step S12 in FIG. 4) and the thermal power control information is transmitted to the cooking device 200 (step S16 in FIG. 4), the second detection information is received by the communication unit 13. Suppose it was done. In this case, the control unit 14 generates the thermal power control information instructing to return to the predetermined thermal power indicated by the thermal power information included in the cooking condition information read from the storage unit 12. Then, this thermal power control information is transmitted from the terminal 100 to the cooking device 200. When the communication unit 23 receives the thermal power control information, the control unit 24 of the cooking device 200 controls the thermal power of the functional unit 21 based on the thermal power control information. As a result, the thermal power in the functional unit 21 is changed to a predetermined thermal power.

As described above, according to this modification, when the user returns to the kitchen, the heating power can be changed to an appropriate level regardless of the user's operation.

<Modification example 4>
For example, when a user who has left the kitchen returns to the kitchen after transmitting the heat control information to the cooking device 200, the control of the cooking utensil such as a pot is controlled to reduce the heat or stop the fire. It is possible that the temperature has dropped. In such a case, the heating power may be controlled to increase until the temperature returns to the temperature at which the user left the kitchen. A specific example of this will be described below.

For example, when the first detection information is received (step S12 in FIG. 4), the communication unit 13 of the terminal 100 receives the request information requesting the transmission of the temperature information indicating the temperature of the cooking utensil together with the thermal power control information. Send to 200.

Next, when the control unit 24 of the cooking equipment 200 receives the thermal power control information and the request information by the communication unit 23, the control unit 24 acquires the temperature information (hereinafter referred to as the first temperature information) detected by the temperature sensor (not shown). , The functional unit 21 is controlled based on the thermal power control information (for example, the information instructing the change from medium heat to low heat). Then, the communication unit 23 transmits the first temperature information to the terminal 100.

Next, the control unit 14 of the terminal 100 stores the first temperature information received by the communication unit 13 in the storage unit 12. After that, when the second detection information is received by the communication unit 13, the communication unit 13 transmits the request information to the cooking device 200 again. Upon receiving this request information, the cooking apparatus 200 transmits the temperature information (hereinafter referred to as the second temperature information) to the terminal 100 in the same manner as described above.

Next, the control unit 14 of the terminal 100 stores the second temperature information received by the communication unit 13 in the storage unit 12. Then, the control unit 14 reads the first temperature information and the second temperature information from the storage unit 12 at a predetermined timing, and the difference between the temperature of the second temperature information and the temperature of the first temperature information is equal to or more than a predetermined threshold value. Determine if it exists.

As a result of the above determination, when the difference between the temperature of the second temperature information and the temperature of the first temperature information is equal to or greater than a predetermined threshold value, the control unit 14 generates thermal power control information. For example, the control unit 14 changes to a heating power (high heat) stronger than the predetermined heating power (for example, medium heat) indicated by the heating power information included in the cooking condition information read from the storage unit 12, and then the first first. When the temperature of the temperature information is reached, the thermal power control information instructing to change to the predetermined thermal power (for example, medium heat) indicated by the thermal power information is generated. Then, this thermal power control information is transmitted from the terminal 100 to the cooking device 200.

When the communication unit 23 receives the thermal power control information, the control unit 24 of the cooking device 200 controls the thermal power of the functional unit 21 based on the thermal power control information. As a result, the thermal power in the functional unit 21 is changed from low heat to high heat, and then changed to medium heat when the temperature of the first temperature information is detected by the temperature sensor.

As described above, according to this modification, when the difference between the temperature of the cooking utensil when the user leaves the kitchen and the temperature of the cooking utensil when the user returns to the kitchen is equal to or more than a predetermined threshold value, It is possible to return to the temperature of the cooking utensil when the user leaves the kitchen in a short time, and the user can proceed with cooking smoothly.

<Modification 5>
For example, when a predetermined control method is performed based on the thermal power control information, the terminal 100 may output information indicating the content of the control method (hereinafter, referred to as notification information). A specific example of this will be described below.

For example, when a control method for changing from medium heat to low heat is performed based on thermal power control information, the control unit 14 of the terminal 100 uses at least one of an image and a sound indicating that the heat has been changed from medium heat to low heat as notification information. The output unit 11 is controlled so as to output. The output of this notification information may be performed only when, for example, the thermal power control information is transmitted to the cooking device 200, or from the time when the thermal power control information is transmitted to the cooking device 200 to the time when the second detection information is received. May be done during.

In the above description, the terminal 100 outputs the notification information, but the cooking device 200 may output the notification information. In this case, the control unit 24 of the cooking device 200 controls the output unit (not shown) of the cooking device 200 so as to output the notification information received from the terminal 100.

Thus, according to this modification, it is possible to recognize that the change in thermal power has been made when the user leaves the kitchen or returns to the kitchen.

<Modification 6>
In the above embodiment, the case where the terminal 100 specifies the heating method being executed by the cooking device 200 based on the recipe information (for example, see FIG. 2) corresponding to the cooking process image being output has been described. The method is not limited to this. For example, when the cooking apparatus 200 has a plurality of heating modes (modes that operate according to the type of heating method, for example, a mode for "simmering", a mode for performing "steaming", etc.) When the heating method is started in the cooking apparatus 200, information indicating the heating mode may be received from the cooking apparatus 200, and the heating method being executed in the cooking apparatus 200 may be specified based on the heating mode indicated by the information.

<Modification 7>
In the above embodiment, the motion sensor 300 is used as a means for detecting whether or not there is a user in the kitchen (hereinafter, user detection means), but the present invention is not limited to this. Hereinafter, other examples of the user detection means will be described.

For example, a camera capable of photographing the entire kitchen and an image processing device that performs image analysis on the image captured by the camera and recognizes whether or not the user is in the kitchen may be used. In this case, both the camera and the image processing device may be provided outside the terminal 100 or inside the terminal 100. Alternatively, the camera may be provided outside the terminal 100 and the image processing device may be provided inside the terminal 100. When the image processing device is provided outside the terminal 100, the image processing device shall have a function of transmitting information indicating the result of image recognition (an example of detection information) to the terminal 100.

Further, for example, a tag that is carried by the user and stores the user's identification information and a reader that acquires the identification information from the tag by short-range wireless communication may be used. As such a technique, for example, there is RFID (Radio Frequency IDentifier). The reader may be provided outside the terminal 100, or may be provided inside the terminal 100. When the reader is provided outside the terminal 100, the reader shall have a function of transmitting the identification information acquired from the tag to the terminal 100.

Then, the control unit 14 of the terminal 100 allows the user to use the identification information while the communication unit 13 receives the identification information from the external reader or the reader built in the terminal 100 acquires the identification information. Determined to be in the kitchen. Then, the control unit 14 performs the same processing operation as when receiving the second detection information described in the above embodiment.

On the other hand, in the control unit 14, the user leaves the kitchen while the communication unit 13 does not receive the identification information from the external reader or the reader built in the terminal 100 does not acquire the identification information. Judged as Then, the control unit 14 performs the same processing operation as when receiving the first detection information described in the above embodiment.

In the above, indoor positioning technology may be used. For example, whether or not the user is in the kitchen based on the information indicating the user's position measured based on the identification information acquired from the tag and the information indicating the predetermined kitchen position (which may be an area). May be determined. This determination may be made by, for example, the reader or the control unit 14 of the terminal 100.

Further, for example, a cooking utensil containing a human body communication module in which user identification information is stored and a transmission device capable of short-range wireless communication between the terminal 100 may be used. In this case, when the user touches the cooking utensil, the identification information is transmitted from the human body communication module to the transmitting device. Then, the transmitting device transmits the identification information received from the human body communication module to the terminal 100.

Then, the control unit 14 of the terminal 100 determines that the user is in the kitchen when the identification information from the transmission device is received by the communication unit 13. Then, the control unit 14 performs the same processing operation as when receiving the second detection information described in the above embodiment.

On the other hand, when the communication unit 13 no longer receives the identification information from the transmission device, the control unit 14 determines that the user has left the kitchen. Then, the control unit 14 performs the same processing operation as when receiving the first detection information described in the above embodiment.

Also, for example, a microphone that inputs the sound generated during cooking (for example, the sound of using a kitchen knife, the sound of flowing water, etc.) or the user's voice, and sound recognition or voice recognition for the sound input to the microphone. A sound recognition device or a voice recognition device may be used to recognize whether or not the user is in the kitchen. In this case, both the camera and the voice processing device may be provided outside the terminal 100 or inside the terminal 100. Alternatively, the microphone may be provided outside the terminal 100, and the voice processing device may be provided inside the terminal 100. When the voice processing device is provided outside the terminal 100, the voice processing device shall have a function of transmitting information indicating the result of voice recognition (an example of detection information) to the terminal 100.

The other examples of the user detection means have been described above. By appropriately combining the above-mentioned user detection means and the motion sensor 300, more accurate detection may be realized.

<Modification 8>
The control unit 14 of the terminal 100 may determine whether or not the person who has returned to the kitchen is the same as the person who has left the kitchen. In this case, the combination of the camera and the image processing device or the combination of the tag and the reader described in the above-described modification 7 can be used. In the former case, the analysis result of the image taken when the user leaves the kitchen (for example, face recognition) and the analysis result of the image taken when the user returns to the kitchen are the same. In addition, both (the person who left the kitchen and the person who returned to the kitchen) are determined to be the same person. In the latter case, if the identification information acquired when the user leaves the kitchen and the identification information acquired when the user returns to the kitchen are the same, both are determined to be the same person. To.

Then, for example, when the control unit 14 makes the above determination within a certain period of time (for example, between steps S12 and S14 in FIG. 4) from the time when the first detection information is received, the control unit 14 operates as follows. For example, when it is determined that both are the same person, the control unit 14 does not execute the generation of the thermal power control information indicating the control method for reducing the thermal power (for example, step S15 in FIG. 4). That is, in this case, the thermal power when the user leaves the kitchen is maintained. This is because if the person who returned to the kitchen is the user himself / herself, even if the firepower is maintained, the risk is considered to be small. On the other hand, for example, when it is determined that they are not the same person, the control unit 14 executes generation of thermal power control information (for example, step S15 in FIG. 4) indicating a control method for reducing the thermal power. That is, in this case, the firepower when the user leaves the kitchen will be reduced.

Further, for example, when the control unit 14 makes the above determination after generating the thermal power control information indicating the control method for reducing the thermal power (for example, step S15 in FIG. 4), the control unit 14 operates as follows. For example, when it is determined that both are the same person, the generation of the thermal power control information indicating the control method for returning the thermal power (for example, the control method described in the modified examples 3 and 4) is executed. That is, in this case, the thermal power reduced by the control method for reducing the thermal power returns to the predetermined thermal power. This is because if the person who returned to the kitchen is the user himself / herself, even if the firepower is returned, the risk is considered to be small. On the other hand, for example, when it is determined that they are not the same person, the control unit 14 stops generating thermal power control information indicating a control method for returning the thermal power (for example, the control method described in the modified examples 3 and 4). To do. That is, in this case, the execution of the control method for reducing the thermal power is maintained.

As described above, according to the present modification, even if a person other than the user enters the kitchen, the control for reducing the thermal power described in the embodiment is not executed, or the thermal power described in the modifications 3 and 4 is not executed. The control to undo is not executed.

In the above explanation, it is determined whether or not the person who returned to the kitchen is the same as the person who left the kitchen, but whether or not the person who entered the kitchen is a pre-registered cook. You may judge. The cook here is a person other than the user who has left the kitchen, and is a person who takes over cooking (for example, a couple). The determination here can also be realized by using a combination of a camera and an image processing device or a combination of a tag and a reader, as in the above description.

For example, when the control unit 14 makes the above determination within a certain period of time (for example, between steps S12 and S14 in FIG. 4) from the time when the first detection information is received, the control unit 14 operates as follows. For example, when it is determined that the person who has entered the kitchen is a pre-registered cook, the control unit 14 generates thermal power control information indicating a control method for reducing the thermal power (for example, step S15 in FIG. 4). Do not execute. On the other hand, for example, when it is determined that the person who has entered the kitchen is not a pre-registered cook, the control unit 14 generates thermal power control information indicating a control method for reducing the thermal power (for example, the step of FIG. 4). S15) is executed.

Further, for example, when the control unit 14 makes the above determination after generating the thermal power control information indicating the control method for reducing the thermal power (for example, step S15 in FIG. 4), the control unit 14 operates as follows. For example, when it is determined that the person who has entered the kitchen is a pre-registered cook, the thermal power control information indicating the control method for returning the thermal power (for example, the control method described in the modified examples 3 and 4) Perform generation. In this case, the thermal power may be restored after outputting a voice or an image indicating that the thermal power is to be restored. Alternatively, for safety, the heating power may be restored when a voice or an image indicating "Do you want to take over the cooking?" Is output and an operation to approve the taking over is accepted by the cook. On the other hand, for example, when it is determined that the person who has entered the kitchen is not a pre-registered cook, the control unit 14 returns the heating power to the original control method (for example, the control method described in the modifications 3 and 4). ) Is stopped.

Further, in the above description, it is determined whether or not the person who returned to the kitchen is the same as the person who left the kitchen, but it may be determined whether or not the person who entered the kitchen is a child. .. For example, the control unit 14 estimates the height of a person who has entered the kitchen based on the detection result by the infrared sensor or the analysis result of the image by the image processing device, and when the estimated height is equal to or less than the threshold value, the person Is determined to be a child.

Then, for example, within a certain period of time from the time when the first detection information is received (for example, between steps S12 to S14 in FIG. 4), or generation of thermal power control information indicating a control method for reducing the thermal power (for example, in FIG. 4). In any of the steps after step S15), when it is determined that the person who has entered the kitchen is a child, the control unit 14 outputs an alarm sound and controls to stop all heating.
