As shown in FIG. 5, the information terminal 80 includes a control circuit 81, a display section 82, an operation section 83, and a communication section 84. The information terminal 80 is configured as a portable information processing terminal such as a smartphone or a tablet terminal, and can operate using a secondary battery (not shown) as a power source. Although the information terminal 80 configured as a smartphone is illustrated in FIGS. 1 and 5, a configuration other than a smartphone may be used as long as it is a portable terminal having an information processing function.

The control circuit 81 is configured as a known information processing device such as a microcomputer, and includes a known arithmetic device such as a CPU and other peripheral circuits, and is capable of performing various controls and calculations. The display section 82 is, for example, a display section that forms part of a known touch panel display device, and is configured as a known image display device such as a liquid crystal display or an organic electroluminescent display. The operation unit 83 is configured, for example, as a known touch panel disposed to cover the front of the display unit 82, and has a transparent configuration that covers the display unit 82 so that the image on the display unit 82 can be viewed from the outside. . Note that the example shown here is just an example, and the display unit 82 may have any configuration as long as it can display an image in a state that the user can visually recognize. The operation unit 83 may have any configuration as long as it allows information to be input by user operation, and may include an input interface (buttons, etc.) other than a touch panel.

The communication unit 84 is a device that can perform wireless communication with an external device using one or more communication methods, such as the first wireless communication method (e.g., WiFi (registered trademark), LTE (Long Term Evolution), and the fourth wireless communication method). The communication device is capable of performing wireless communication using a communication method according to a known wireless communication standard such as a generation mobile communication system or a fifth generation mobile communication system. The communication unit 84 has a function of being able to access the wide area communication network 91 directly or indirectly via another device by wireless communication using the first wireless communication method, for example, and has the function of accessing the wide area communication network 91 directly or indirectly via another device, and 1 communication unit 74 . Specifically, the control circuit 81 and the communication unit 84 can cooperate to transmit and receive information to and from the relay terminal 70. Further, when the stove body 1A and the relay terminal 70 are paired, the control circuit 81 and the communication section 84 cooperate to transmit and receive information to and from the stove body 1A.

Next, communication control by the cooking system 100 will be explained.
In the cooking system 100, the gas stove 1 performs wireless communication with an information terminal 80 via a relay terminal 70. An application program (cooking application) related to the control of the cooking system 100 is installed on the relay terminal 70 and the information terminal 80, and with the application started on each terminal, the gas stove 1 is connected to the information terminal via the relay terminal 70. Communicate with 80. The application program installed in the information terminal 80 is a program that can execute control as shown in FIG. The application program installed in relay terminal 70 is a program that can execute control as shown in FIG. Further, the gas stove 1 stores a program that can execute control as shown in FIG.

FIG. 6 illustrates the flow of control performed in the cooking system 100. FIG. 6 illustrates a case where the user performs a fire extinguishing operation (an operation instructing the gas stove 1 to extinguish the fire) using the information terminal 80. In this example, the user operates the operation unit 83 of the information terminal 80 to input information instructing to extinguish all gas burners of the gas stove 1 (each stove section 4A, 4B, 4C, and grill 3) (extinguishing operation). It is carried out. When such a fire extinguishing operation (input of information instructing fire extinguishing) is performed, the information terminal 80 transmits a command (extinguishing operation command) corresponding to the fire extinguishing operation to the server 90. This extinguishing operation command is a command to extinguish all gas burners. Further, after starting the transmission of the fire extinguishing operation command, the information terminal 80 displays on the display unit 82 a dialog display indicating that the fire extinguishing operation command is being transmitted. When the server 90 receives the fire extinguishing operation command, the server 90 transmits a fire extinguishing request notification corresponding to the fire extinguishing operation command to the relay terminal 70 and causes the relay terminal 70 to perform a push notification. This fire extinguishing request notification is for notifying the fire extinguishing operation command (command for extinguishing all gas burners), and is information that notifies the relay terminal 70 that there is a fire extinguishing operation command from the information terminal 80. Upon receiving the fire extinguishing request notification, the relay terminal 70 transmits a fire extinguishing request command to the gas stove 1 . The fire extinguishing request command is a command corresponding to a fire extinguishing request notification from the server 90 (that is, a command corresponding to a fire extinguishing operation command from the information terminal 80), and is a command that corresponds to a fire extinguishing operation command from the information terminal 80 that transmitted the command (all This is information that gives a command to the gas stove 1 to extinguish the gas burner.

When the gas stove 1 receives a command from the relay terminal 70, it performs an operation according to the received command.As mentioned above, the gas stove 1 receives the extinguishing request command (extinguishing all gas burners) from the relay terminal When a command to instruct the fire extinguisher is received, an operation (extinguishing operation) to extinguish all gas burners is performed in accordance with the received extinguishing request command.

When the gas stove 1 receives a command from the relay terminal 70 and starts an operation (extinguishing operation) according to the command, it informs the relay terminal 70 that the operation according to the received command is being executed. Sends a response command. For example, when the gas stove 1 starts the operation according to the extinguishing request command (extinguishing all gas burners) in response to receiving the extinguishing request command from the relay terminal 70, the gas stove 1 starts the operation according to the extinguishing request command (extinguishing all gas burners). A command indicating that the operation of extinguishing the gas burner (extinguishing the gas burner) is being executed (extinguishing execution command) is transmitted to the relay terminal 70.

When the relay terminal 70 receives the above-mentioned response command, it transmits to the server 90 a notification that the execution corresponding to the response command is in progress. For example, when the relay terminal 70 receives the above-mentioned fire extinguishing command as a response command, the relay terminal 70 notifies the server 90 that the fire is being extinguished (information indicating that the fire is being extinguished (stove operation)) corresponding to the fire extinguishing command. Send result notification)).

When the server 90 receives the above-mentioned "notification of execution" from the relay terminal 70, it transmits information corresponding to the "notification of execution" to the information terminal 80 and sends a push notification to the effect that the execution is in progress. Let it happen. For example, when the server 90 receives a notification that the fire is being extinguished from the relay terminal 70 (information indicating that the fire is being extinguished (stove operation result notification)), information corresponding to the notification that the fire is being extinguished is sent to the information terminal 80. (notification that fire extinguishing is in progress) to send a push notification that fire extinguishing is in progress (extinguishing operation in progress).

After displaying the above-mentioned dialog, the information terminal 80 displays a screen (specifically, Display a screen corresponding to "information corresponding to the notification being executed"). For example, when the information terminal 80 receives a fire extinguishing notification from the server 90 (information corresponding to the fire extinguishing notification from the relay terminal 70) after displaying the above dialog, the information terminal 80 responds to the fire extinguishing notification in response to the fire extinguishing notification. A screen displaying the status of the gas stove 1 is displayed on the display unit 82 (for example, a "extinguishing operation in progress" screen corresponding to the notification that fire extinguishing is in progress as shown in FIG. 6) is displayed. In the example of FIG. 6, the screen displaying the status of the gas stove 1 displays, for example, an image representing the image of the gas stove 1, as well as symbols and characters representing the status corresponding to each stove part 4A, 4B, 4C, and grill 3. Ru. In FIG. 6, when each stove section 4A, 4B, 4C and grill 3 are in the process of extinguishing the fire, "?" is displayed corresponding to each stove section 4A, 4B, 4C and grill 3. The "?" mark is a mark indicating that the part (stove part or grill) marked with "?" is in the process of extinguishing the fire. Note that if the information terminal 80 does not receive the fire extinguishing completion command described below even after a predetermined period of time (for example, 10 seconds) has passed since transmitting the fire extinguishing operation command described above, the information terminal 80 displays a message to that effect (for example, a timeout). The display unit 82 causes the display unit 82 to display a message indicating that The above-mentioned display indicating that the predetermined time has elapsed (for example, the display indicating that the time has expired) is displayed in the form of an additional display (for example, an additional display such as a speech bubble) added to the "extinguishing operation in progress" screen shown in Figure 6. The timeout may be displayed, or the screen may be temporarily switched to display that the timeout has occurred.

When the gas stove 1 receives a command from the relay terminal 70, it performs an operation according to the received command, and when this operation is completed, it transmits a command according to the completion of the operation to the relay terminal 70. For example, after transmitting the above-mentioned fire extinguishing execution command, the gas stove 1 transmits a fire extinguishing completion command corresponding to the completion of the fire extinguishing operation to the relay terminal 70 when the fire extinguishing operation (extinguishing operation) is completed.

When the relay terminal 70 receives a command corresponding to the completion of the operation from the gas stove 1, it transmits information to the server 90 that the operation is completed (operation result notification). For example, when the relay terminal 70 receives a fire extinguishing completion command from the gas stove 1, it transmits information to the server 90 indicating that the fire extinguishing has been completed (stove operation result notification).

When the server 90 receives information indicating that the operation has been completed (operation result notification) from the relay terminal 70, the server 90 transmits information indicating that the operation has been completed to the information terminal 80, and causes the information terminal 80 to perform a push notification. For example, when the server 90 receives information from the relay terminal 70 that the fire extinguishing has been completed, the server 90 transmits the information that the fire extinguishing has been completed to the information terminal 80 and causes the information terminal 80 to issue a push notification.

When the information terminal 80 receives information indicating that the operation has been completed from the server 90, the information terminal 80 changes the screen display (display of the status of the gas stove 1) on the display unit 82 to a screen display that corresponds to the information that the operation has been completed. Update. For example, when the information terminal 80 receives information from the server 90 that the fire extinguishment has been completed, the information terminal 80 changes the screen display (display of the status of the gas stove 1) on the display unit 82 according to the information that the fire extinguishment has been completed. Update the screen display. In this case, as shown in FIG. 6, for example, the display section 82 displays information corresponding to each stove section 4A, 4B, 4C, and grill 3 when the fire has been completely extinguished in each stove section 4A, 4B, 4C, and grill 3. The word "off" is displayed.

Next, the control performed by each device of the gas stove 1, the relay terminal 70, and the information terminal 80 will be explained in detail.
First, the control performed by the information terminal 80 will be explained. The process shown in FIG. 7 is a process executed by the control circuit 81 in the information terminal 80. The control circuit 81 detects that an operation for remotely controlling the gas stove 1 (an operation for transmitting a command to the gas stove 1) is performed on the operation unit 83 while the above-mentioned cooking application is activated. (Step S11), the process of FIG. 7 is started. In addition, in the process of FIG. 7, the second control is started by the control circuit 10 and the control circuit 71 of the gas stove 1, and the first wireless communication method or the second wireless communication method is further performed between the information terminal 80 and the relay terminal 70. It is assumed that wireless communication is possible. In subsequent step S12, the control circuit 81 relays an operation command (for example, a command to extinguish any one of the stove parts 4A, 4B, 4C, and the grill 3) via the communication unit 84 via the server 90. It is transmitted to the terminal 70. Then, in step S13, the control circuit 81 causes the display unit 82 to display that the operation command is being transmitted.

In subsequent step S<b>14 , the control circuit 81 determines whether or not a notification that the operation related to the operation command is being executed on the gas stove 1 has been received from the relay terminal 70 via the server 90 . If the control circuit 81 determines that it has received a notification that the operation related to the operation command is being executed on the gas stove 1, the process proceeds to Yes and performs step S16. On the other hand, if the control circuit 81 determines that it has not received the notification that the operation related to the operation command is being executed on the gas stove 1, the process proceeds to No, and in step S15, the control circuit 81 updates the operation command performed in step S12. It is determined whether a predetermined time (for example, 10 seconds) has elapsed since the time of transmission (whether or not it is a timeout). If the control circuit 81 determines that the timeout has occurred, the process proceeds to Yes and performs step S16. On the other hand, if the control circuit 81 determines that the timeout has not occurred, the process proceeds to No and performs step S14 again.

The control circuit 81 causes the display section 82 to switch the display in step S16. Specifically, the control circuit 81 causes the display unit 82 to transition to a screen (see FIG. 6) that displays the status of the gas stove 1, as described above. For example, as shown in FIG. 6, when each of the stoves 4A, 4B, 4C and the grill 3 are in the process of extinguishing the fire, the display section 82 displays " ?” is displayed.

In subsequent step S17, the control circuit 81 determines whether a notification regarding completion of extinguishing the fire has been received from the relay terminal 70 via the server 90. When the control circuit 81 determines that the notification regarding the completion of extinguishing the fire has been received from the relay terminal 70, the process proceeds to Yes and performs step S17. On the other hand, if the control circuit 81 determines that the notification regarding the completion of extinguishing has not been received from the relay terminal 70, the process proceeds to No, and repeats step S17 until it determines that the notification regarding the completion of extinguishing has been received from the relay terminal 70. . In step S18, the control circuit 81 causes the display unit 82 to update the display of the state of the gas stove 1. For example, as shown in FIG. 6, when each of the stove sections 4A, 4B, 4C, and the grill 3 have been completely extinguished, the display section 82 displays "extinguishing" corresponding to each of the stove sections 4A, 4B, 4C, and the grill 3. ' will be displayed. When step S18 is performed, the control circuit 81 ends the process of FIG. 7.

Next, control performed by relay terminal 70 will be explained. The process shown in FIG. 8 is a process executed by the control circuit 71 in the relay terminal 70. The control circuit 71 starts the process shown in FIG. 8 by starting the cooking application described above. It is assumed that the process in FIG. 8 is performed in a state where the second control is started by the control circuit 10 and the control circuit 71 of the gas stove 1.

In step S21, the control circuit 71 receives an instruction from the information terminal 80 via the server 90 to the gas stove 1 (an operation command, for example, a command to extinguish any one of the stove sections 4A, 4B, 4C, and the grill 3). Determine whether or not has been input. When an instruction (command) is input to the second communication section (input section) 75, the control circuit 71 causes the second communication section 75 to wirelessly transmit the instruction to the gas stove 1 using the second wireless communication method. Control. When the control circuit 71 determines that an instruction for the gas stove 1 has been input from the information terminal 80, it performs step S22. On the other hand, if the control circuit 71 determines that no instruction to the gas stove 1 has been input from the information terminal 80, it repeatedly performs step S21 until it determines that an instruction has been input. In step S22, the control circuit 71 sends commands to the gas stove 1 (for example, each stove section 4A, 4B, 4C, grill A fire extinguishing command requesting extinguishing of one of the following items is sent.

In the subsequent step S23, the control circuit 71 receives an execution command (for example, a command indicating that one of the stove sections 4A, 4B, 4C, and the grill 3 is being extinguished) from the gas stove 1. Decide whether or not. When the control circuit 71 determines that the command being executed has been received, it performs step S24. On the other hand, if the control circuit 71 determines that it has not received the command in progress, it repeatedly performs step S23 until it determines that it has received the command in progress.

When the information on the status of the gas stove 1 is wirelessly transmitted from the gas stove 1, the control circuit 71 displays a display according to the information on the status of the gas stove 1 (a display indicating that a command is being executed, which will be described later, or a message indicating that the command has been completed). display) on the display section 72. For example, in step S24, the control circuit 71 causes the display unit 72 to display (in accordance with the status information) that the gas stove 1 is executing a command (for example, a fire extinguishing request command). The display in step S24 may be a display of text information indicating that the gas stove 1 is executing a command (for example, a fire extinguishing request command), a pictorial display to that effect, or a display using a combination of these. It may be. In the subsequent step S25, the control circuit 71 transmits information to the information terminal 80 via the server 90 that the fire extinguishing is in progress.

In subsequent step S26, the control circuit 71 determines whether a completion command (for example, a command indicating that extinguishing of any one of the stove sections 4A, 4B, 4C, and the grill 3 has been completed) has been received from the gas stove 1. to decide. When the control circuit 71 determines that the completion command has been received, it performs step S27. On the other hand, if the control circuit 71 determines that the completion command has not been received, it repeatedly performs step S26 until it determines that the completion command has been received.

In step S27, the control circuit 71 causes the display unit 72 to display that the gas stove 1 has finished extinguishing (a display according to the status information). The display in step S27 may be a display of text information indicating that extinguishing of the gas stove 1 has been completed (for example, that all gas burners are extinguished), or may be a pictorial display to that effect. , or a combination of these may be used. In the following step S28, the control circuit 71 transmits information to the information terminal 80 via the server 90 that the fire extinguishment is complete. When step S28 is performed, the control circuit 71 ends the process of FIG. 8.

Next, the control performed by the gas stove 1 will be explained. The process shown in FIG. 9 is a process executed by the control circuit 10 in the gas stove 1. The control circuit 10 starts the process shown in FIG. 9 by starting the cooking application described above. It is assumed that the process in FIG. 9 is performed in a state where the second control is started by the control circuit 10 and the control circuit 71 of the gas stove 1.

In step S31, the control circuit 10 determines whether a command (for example, a fire extinguishing command requesting extinguishing of any one of the stove sections 4A, 4B, 4C, and the grill 3) has been transmitted from the relay terminal 70. When the control circuit 10 determines that the command has been transmitted from the relay terminal 70, it performs step S32. On the other hand, when the control circuit 10 determines that no command has been transmitted from the relay terminal 70, it repeatedly performs step S31. In step S32, control circuit 10 receives a command from relay terminal 70.

When an instruction (command) is wirelessly transmitted from the information terminal 80, the control circuit 10 causes the gas stove 1 to perform an operation according to the instruction. In step S33, the control circuit 10 executes the operation corresponding to the command received in step S32. The control circuit 10 stores in advance operations corresponding to commands. For example, the control circuit 10 stores an operation for extinguishing any one of the stove sections 4A, 4B, 4C, and the grill 3 in response to a fire extinguishing command. Specifically, the control circuit 10 stores an operation for extinguishing the stove section 4A in response to a fire extinguishing command including a command to extinguish the stove section 4A, and an operation for extinguishing the stove section 4A in response to an extinguishing command including a command to extinguish the stove section 4B. Correspondingly, an action for extinguishing the stove section 4B is stored, and an operation for extinguishing the stove section 4C is stored in response to a fire extinguishing command including a command to extinguish the grill section 4C, including a command for extinguishing the grill 3. An operation for extinguishing the grill 3 in response to a fire extinguishing command is stored. Therefore, for example, when the control circuit 10 receives a fire extinguishing command including a command to extinguish the stove section 4A, it extinguishes the stove section 4A.

The control circuit 10 controls the communication unit 11 to wirelessly transmit information on the state of the gas stove 1 (such as an executing command and a completed command to be described later) to the relay terminal 70 during the first control. In step S<b>34 , the control circuit 10 transmits an execution command (for example, a command indicating that one of the stove sections 4</b>A, 4</b>B, 4</b>C, and the grill 3 is being extinguished) to the relay terminal 70 . . In the following step S35, the control circuit 10 determines whether the completion condition for the operation corresponding to the command is satisfied. For example, if the electromotive force generated in any of the thermocouples installed in each of the stove sections 4A, 4B, 4C and the grill 3 falls below a predetermined threshold, the condition for extinguishing the fire at the stove or grill where the thermocouple is installed is has been established. When the control circuit 10 determines that the completion condition is satisfied, it performs step S36. On the other hand, if the control circuit 10 determines that the completion condition is not satisfied, it repeatedly performs step S35. In step S36, the control circuit 10 transmits a completion command to the relay terminal 70 (for example, a command indicating that the extinguishing of any one of the stove sections 4A, 4B, 4C, and the grill 3 has been completed). When step S36 is performed, the control circuit 10 ends the process of FIG.

As described above, the gas stove 1 uses the relay terminal 70 and the WiFi (registered trademark) communication method (first wireless communication method), which has lower power consumption than the Bluetooth (registered trademark) communication method (second wireless communication method). wireless communication is performed to exchange information (steps S32, S34, S36). Therefore, it is not necessary to provide the gas stove 1 with a communication function using the WiFi (registered trademark) communication method, and the power consumption of the gas stove 1 can be reduced. In addition, there is no need to connect the gas stove 1 to a wired LAN, and there is no need to provide a LAN cable connector on the gas stove 1 for connection to a router installed indoors, simplifying the configuration of the gas stove 1. Can be done.

The effect of this configuration will be illustrated.
The cooking system 100 described above uses wireless communication between the stove body 1A and the relay terminal 70 using a second wireless communication method (a communication method different from the first communication method for the relay terminal 70 to access the wide area communication network 91). Wireless communication can be performed with the information terminal 80 via the relay terminal 70 while performing wireless communication. Therefore, the stove body 1A can now perform wireless communication with the information terminal 80 without performing wireless communication using the first communication method between the stove body 1A and the relay terminal 70. It is possible to enjoy the advantages of performing wireless communication by adopting the second wireless communication method without adopting the communication method. In particular, the registration unit 13 is configured to maintain registration of identification information of terminals that are permitted to communicate even when the stove body 1A is powered off. It is possible to reduce power consumption without communicating with the relay terminal 70, and when the stove body 1A is powered on, communication with the relay terminal 70 is immediately started in response to the identification information given from the relay terminal 70. can be established.

In the cooking system 100 described above, the first wireless communication method is the WiFi (registered trademark) communication method, and the second wireless communication method is the Bluetooth (registered trademark) communication method.
This cooking system 100 employs the WiFi (registered trademark) communication method as the first wireless communication method for the relay terminal 70 to access the wide area communication network 91, and the second wireless communication method for the stove body 1A to communicate with the relay terminal 70. Since the Bluetooth (registered trademark) communication method is adopted as the wireless communication method, power consumption can be further suppressed in wireless communication between the stove body 1A and the relay terminal 70, and in particular, the power consumption of the stove body 1A can be reduced. This is a configuration that has great advantages in suppressing the

In the cooking system 100 described above, the control circuit 10 and the control circuit 71 cooperate to perform the second control so as to wirelessly transmit information about the gas stove 1 to the information terminal 80.
In this cooking system 100, in accordance with the second control, the information terminal 80 can acquire information about the stove body 1A that is wirelessly transmitted from the stove body 1A. Therefore, while the stove body 1A enjoys the benefits of the second wireless communication method, the information terminal 80 can acquire information about the stove body 1A at a position away from the stove body 1A.

In the cooking system 100 described above, the relay terminal 70 has an input section (for example, the second communication section 75) into which instructions for the gas stove 1 are input. The control circuit 71 controls the second communication unit 75 to wirelessly transmit the instruction to the gas stove 1 using the second wireless communication method when an instruction is input to the input unit. The control circuit 10 causes the gas stove 1 to perform an operation according to the instruction when the instruction is wirelessly transmitted from the relay terminal 70.
If the cooking system 100 is configured in this way, the user can give instructions to the stove body 1A via the relay terminal 70 by inputting instructions to the stove body 1A into the input section of the relay terminal 70. , the stove body 1A can operate according to the instructions. Therefore, the cooking system 100 described above is a system in which the stove body 1A can operate in response to remote instructions from the relay terminal 70 while enjoying the benefits of the second wireless communication method.

In the cooking system 100 described above, the relay terminal 70 has a display section 72. The control circuit 10 controls the communication unit 11 to wirelessly transmit information on the state of the gas stove 1 to the relay terminal 70 during the first control. The control circuit 71 causes the display unit 72 to display information according to the status information when the status information of the gas stove 1 is wirelessly transmitted from the gas stove 1 .
In this cooking system 100, the relay terminal 70 can acquire information on the state of the stove body 1A in response to the first control, and the relay terminal 70 can display information according to the state information. . Therefore, as long as the user is near the relay terminal 70, the user can check the status of the stove body 1A even if the user and the relay terminal 70 are a certain distance from the stove body 1A.

<Other embodiments>
The invention is not limited to the embodiments described above and illustrated in the drawings. For example, the features of the embodiments described above or below can be combined in any combination without contradicting each other. Furthermore, any feature of the embodiments described above or below may be omitted unless explicitly stated as essential. Furthermore, the embodiment described above may be modified as follows.

In the first embodiment, in the control performed by the relay terminal 70, in step S21, when an instruction (command) is input to the second communication section (input section) 75, the control circuit 71 transmits the instruction to the gas stove 1. In contrast, the second communication unit 75 was controlled to perform wireless transmission using the second wireless communication method. However, when an instruction (command) for the gas stove 1 is input to the relay terminal 70 by operating the operation unit 73, the control circuit 71 transmits the input instruction to the gas stove 1 using the second wireless communication method. The second communication unit 75 may be controlled to perform wireless transmission. In this case, the operation section 73 corresponds to an example of an "input section." In this case, for example, when a fire extinguishing instruction (command) instructing to extinguish the gas burner 51 is input to the relay terminal 70 by operating the operation unit 73, the control circuit 71 and the second communication unit 75 cooperate, Information instructing to extinguish the gas burner 51 is wirelessly transmitted to the gas stove 1 using the second wireless communication method. When the communication unit 11 receives the wirelessly transmitted “information instructing to extinguish the fire”, the control circuit 10 (stove side control unit) operates in accordance with the instruction (specifically, extinguishes the gas burner 51). make the stove itself perform the following actions.

In the first embodiment, an example was shown in which the information terminal 80 transmits a fire extinguishing request command to the gas stove 1 via the relay terminal 70 (step S12 in FIG. 7, step S22 in FIG. 8). However, the command sent from the information terminal 80 to the gas stove 1 may be other than a request to extinguish fire. For example, it may be a command requesting transmission of information indicating the status of the gas stove 1.

In the first embodiment, an example was shown in which commands are input by operating the operation unit 83 in the information terminal 80 (step S11 in FIG. 7). However, commands may be entered by other methods. For example, the information terminal 80 may be configured to detect voice, and a command may be input based on the detected voice.

In the first embodiment, the relay terminal 70 notifies the state of the gas stove 1 (completion of extinguishing, etc.) by displaying on the display unit 72 (steps S24 and S27 in FIG. 8). However, the relay terminal 70 may notify the state of the gas stove 1 by other methods. For example, the relay terminal 70 is configured to output audio, and may notify the status of the gas stove 1 (completion of extinguishing the fire, etc.) through audio output.

In the description of the first embodiment, an example was shown in which the stove main body 1A and the relay terminal 70 perform short-range wireless communication using the Bluetooth (registered trademark) communication method. However, if it is a short-range wireless communication method that consumes less power than the wireless communication method used by the relay terminal 70 to access the wide area communication network, a short-range wireless communication method other than the Bluetooth (registered trademark) communication method may be used. The second wireless communication method may be employed, and the stove main body 1A and the relay terminal 70 may perform wireless communication using this second wireless communication method.
