Further, the display control unit has a function of setting the display units 41 and 47 to a display mode with low power consumption when communication is being performed with the specific mobile terminal 5.

As the mobile terminal 5, an information communication terminal having an operation display panel 61 having an operation function and a display function and a wireless communication unit 62 capable of wirelessly connecting to an external communication network, a so-called smartphone, is preferably used. The 62 further has a function of wirelessly transmitting and receiving data to and from the gas controller 1. The wireless communication unit 62 of the mobile terminal 5 may be configured to wirelessly connect to an external communication network via an antenna of a communication base station installed outdoors, or may be installed indoors or the like. It may be configured to wirelessly connect to an external communication network via a repeater, or it may be configured to switch to one of the communication modes and wirelessly connect to an external communication network. You may. Further, as the mobile terminal 5, a wireless communication terminal such as a so-called tablet PC, a television receiver having a network communication function, a remote controller, or the like can also be used.

It has a circuit configuration such as a communication control unit that controls the communication operation of the wireless communication unit 62, and an information storage unit that stores information and application programs received by the wireless communication unit 62.

By the way, when using the wireless communication function between the gas stove 1 and the mobile terminal 5, it is necessary to register the mobile terminal 5 to be used in the gas stove 1 in advance. To elaborate on the procedure, first, an application program for remote operation for setting operating conditions such as display of the operating state of the gas stove 1 and recipe data for automatic cooking on the mobile terminal 5 side (hereinafter, "conro operation AP"). ") Is started. As a result, on the operation display panel 61 of the mobile terminal 5, a cooking mode setting button serving as a pseudo operation key for selecting and setting a plurality of cooking modes such as boiling water, simmered food, fried food, and rice cooking, and a heating target temperature for setting. Temperature setting button as a pseudo operation key, thermal power setting button as a pseudo operation key for setting the heating power, timer setting button as a pseudo operation key for setting the heating time, setting of the heating target temperature, heating power, and heating time It is an adjustment button that is a pseudo operation key for adjusting, a connection button that is a pseudo operation key for making communication with the gas stove 1, and a pseudo operation key for changing the setting of the mobile terminal 5. The setting operation screen on which the setting change button and the like are arranged is displayed, and the selection setting of the operating conditions for automatic cooking and the communication setting with the gas stove 1 are possible.

Then, by pressing the setting change button displayed on the operation display panel 61 to select the communication setting mode and then pressing the terminal information transmission button displayed on the operation display panel 61, the terminal information required for registration can be obtained from the gas stove 1. Will be sent to.

On the other hand, on the gas stove 1 side, when the stove power is on, a terminal registration mode selection operation is performed with the setting input switch 46 (for example, after pressing the setting change switch, an operation of selecting the "terminal registration mode" with the adjustment switch. )I do. As a result, the wireless communication unit 42 starts searching for terminal information. That is, the monitoring of whether or not the terminal information is transmitted from the mobile terminal 5 is started. Then, when the terminal information is normally received by the wireless communication unit 42, the terminal information is stored in a specific block of a memory (not shown), and information indicating that the terminal information is normally registered is transmitted by wireless communication. It is transmitted from the unit 42 to the mobile terminal 5, and the registration operation is completed.

In this way, when the terminal information of the mobile terminal 5 to be used is normally registered in the gas stove 1, communication with the gas stove 1 is performed every time the stove operation AP is activated in the mobile terminal 5 with the stove power on. The connection information required for the stove is automatically transmitted from the mobile terminal 5, a terminal connection operation (pairing) is performed, and communication with the mobile terminal 5 becomes possible. On the other hand, if the terminal information is not normally received by the wireless communication unit 42 even after a certain period of time has passed since the search for the terminal information is started, the registration operation is stopped as a time error.

When the operating condition selected and set by the cooking mode button, the timer setting button, or the like is transmitted to the gas stove 1 after the mobile terminal 5 becomes communicable with the gas stove 1, the operation is performed after the operating condition is set. By pressing the operating condition transmission button displayed on the display panel 61, the setting data is transmitted to the gas stove 1.

Next, the control operation of the gas stove 1 when the stove power is turned on will be described with reference to the flowchart shown in FIG.

When the power switch 43 turns on the power of the stove, a dry battery (not shown) can supply the power required for the operation of the entire gas stove 1 to the stove control circuit 15. That is, the stove power is turned on (ST1 to ST2). Although not shown, when the stove power is turned on, the display unit 41 displays the operating state and setting information of the gas stove 1, and the display unit 47 displays the set heating time and heating temperature. Display it. That is, the display units 41 and 47 are set to the standard display form.

Further, when the stove power is turned on, a search for whether or not connection information is transmitted from the mobile terminal 5 registered in advance is performed for a certain period of time (for example, 5 seconds) (ST3). At this time, if the stove operation AP is not activated on the mobile terminal 5 side and the connection information is not transmitted from the mobile terminal 5 (No in the step of ST3), the search is stopped and the burners 21 and 31 are used. Whether or not the ignition operation, the thermal power adjustment operation, and the setting operation of the setting input switch 46 (hereinafter, collectively referred to as "stove operation") have been performed for the first predetermined time S1 (for example, 120 seconds) or more, and the power switch. At 43, monitoring is started to see if the stove power off operation has been performed (ST4 to ST6).

As a result, if the stove operation is not performed for the first predetermined time S1 or more (Yes in the step of ST5), the stove power is automatically turned off and the operation is terminated (ST7). Also, when the user manually turns off the stove power supply (Yes in the step of ST6), the stove power supply is turned off and the operation ends (ST7).

On the other hand, when the stove power is turned on, the stove operation AP is activated on the mobile terminal 5 side, and if the wireless communication unit 42 receives the connection information transmitted from the mobile terminal 5, the connection is made. The information is collated with the registered information stored in the memory (not shown). As a result, if the connection information is recognized as that of the pre-registered mobile terminal 5, the communication connection with the mobile terminal 5 is permitted and the terminal connection operation is terminated (Yes in the step of ST3).

When the registered mobile terminal 5 is manually wirelessly connected to the gas stove 1, the connection information necessary for communication with the gas stove 1 is transmitted from the mobile terminal 5 by pressing the connection button. Then, if the connection information received on the gas stove 1 side is recognized as that of the mobile terminal 5 registered in advance, the communication connection with the mobile terminal 5 is permitted.

When the communication with the mobile terminal 5 becomes possible, the automatic power-off operation described in the steps ST4 to ST6 is not executed, that is, the automatic power-off function is disabled and the second predetermined time S2 (for example, , 90 seconds) or more, the monitoring of whether or not the mobile terminal 5 has been used (here, whether or not the setting operation screen is displayed) is started (ST8 to ST9). The determination as to whether or not the mobile terminal 5 has not been used may be made by determining whether or not any button arranged on the setting operation screen has been pressed.

If it is determined that the mobile terminal 5 has not been used for the second predetermined time S2 or more (Yes in the step of ST9), the process returns to the step of ST3 (if it is set to the power saving display mode described later, it is saved). (Cancel the power display mode setting), and confirm whether or not the communication connection with the mobile terminal 5 is maintained (ST10, ST3). At this time, the mobile terminal 5 and the mobile terminal 5 have finished the stove operation AP, the communication with the mobile terminal 5 is cut off due to poor communication, the power of the mobile terminal 5 is turned off, and so on. If the communication connection is disconnected (No in the step of ST3), the steps after ST4 are performed again. That is, the automatic power off function is enabled.

On the other hand, when it is determined that the mobile terminal 5 is being used within the second predetermined time S2 (Yes in the step of ST8), the display modes of the display units 41 and 47 are set to the power saving display mode with low power consumption. (Here, all lights are turned off) (ST11). As the power saving display mode, the illuminance may be reduced or the display information may be reduced. When a backlight type liquid crystal display panel is used for the display units 41 and 47, only the backlight may be turned off, or only one of the display units 41 and 47 may be turned off to reduce the illuminance. The display information may be restricted.

If the stove is operated after the display mode of the display units 41 and 47 is set to the power saving display mode in the step of ST11, the power saving display mode setting is canceled and the display units 41 and 47 are standardized. (Here, all lights are turned on), and the process returns to the step of ST3 (ST12, ST10, ST3). At this time, if the communication connection with the mobile terminal 5 is canceled (No in the step of ST3), the automatic power off function is enabled again.

If the stove power is turned off after the display mode of the display units 41 and 47 is set to the power saving display mode in the step of ST11 and before the stove is operated, the stove power is turned on. Turn it off and end the operation (ST13, ST7).

According to the gas stove 1, it is determined that there is no communication with the mobile terminal 5 in the state where the stove power is turned on, and the possibility that the burners 21 and 31 are used is low. In this case (here, when communication with the mobile terminal 5 is not performed and the stove is not operated for the first predetermined time S1 or more), the stove power is automatically turned off, which is useless. Power consumption can be suppressed. Therefore, the battery life can be extended accordingly.

On the other hand, when the stove power is turned on and communication is being performed with the mobile terminal 5, the automatic power supply is performed regardless of whether the burners 21 and 31 are unlikely to be used. Since the off operation is not performed, the stove power supply is not automatically turned off during the operation of setting the operating conditions on the mobile terminal 5. Therefore, the usability is also significantly improved.

Moreover, according to the gas stove 1, the display unit 41, while the mobile terminal 5 is being used, that is, while communication with the mobile terminal 5 is being performed after the stove power is turned on. Since the 47 is switched to the display mode with low power consumption, the power consumption of the entire appliance can be suppressed even in the state where the automatic power off operation is not performed as described above. Therefore, the battery life can be extended accordingly.

In the above embodiment, when communication with the mobile terminal 5 is not performed, if the stove is not operated for the first predetermined time S1 or more with the stove power turned on, the stove is automatically operated. Although the stove power is configured to be turned off, it is equipped with a human detection sensor that detects the presence or absence of a person on the front 13 side of the gas stove 1, and communication with the mobile terminal 5 is not performed. In this case, if no person is present on the front surface 13 side of the stove 1 for a third predetermined time S3 (for example, 180 seconds) or more, the stove power may be automatically turned off. In this case, when communication is not performed with the mobile terminal 5, if there is no user in front of the gas stove 1, the stove power is automatically turned off, so that the power consumption is appropriately suppressed. can do. Further, even though there is a user in front of the gas stove 1 for the purpose of using the burners 21 and 31, there is no inconvenience that the stove power is automatically turned off, so that the usability is further improved.

Alternatively, it is provided with a ventilation state determination unit for determining the operating state of the ventilation device installed above the gas stove 1, and is automatically provided if the ventilation device is stopped when communication with the mobile terminal 5 is not performed. It may be configured so that the stove power is turned off. In this case, when communication with the mobile terminal 5 is not performed, the stove power is automatically turned off when the ventilation device is stopped, so that the power consumption can be appropriately suppressed. it can. Further, when the burners 21 and 31 are extinguished and cooking is temporarily interrupted, there is no inconvenience that the stove power is automatically turned off, so that the usability is further improved.

Further, in the above embodiment, when communication is performed with the mobile terminal 5, the burners 21 and 31 can be used regardless of whether or not the burners 21 and 31 are unlikely to be used. Although the configuration is described so as not to perform the sex determination (steps of ST4 to ST5), when communication is being performed with the mobile terminal 5, the operation condition setting operation is performed on the mobile terminal 5. Since it is assumed that the burners 21 and 31 are likely to be used because it is assumed that the burners are in the middle or there is an intention to perform automatic cooking, even if the burners 21 and 31 are configured not to perform the automatic power off operation. Good.

Specifically, as shown in the flowchart of FIG. 4, when the stove power is turned on by the power switch 43, the stove power is turned on as in the steps ST1 to ST2 of the above embodiment. (ST21 to ST22). Although not shown, when the stove power is turned on, the display units 41 and 47 are set to the standard display mode as in the above embodiment.

Further, when the stove power is turned on, whether or not the stove operation has been performed, whether or not the connection information has been transmitted from the pre-registered mobile terminal 5, and whether or not the communication with the mobile terminal 5 has already been performed. It is possible to start monitoring whether or not the mobile terminal 5 is being used (for example, whether or not the setting operation screen is displayed) (ST23).

After that, when the stove operation is performed (Yes in the step of ST23, Yes in the step of ST24), the display units 41 and 47 are maintained in the above standard display mode (even in the state of being set to the power saving display mode). (For example, the power saving display mode setting is canceled), and the power switch 43 monitors whether or not the stove power is turned off. Then, when the stove power off operation is performed, the stove power is turned off and the operation is terminated (ST24 to ST27).

On the other hand, when the stove power is turned on, the stove operation AP is activated on the mobile terminal 5 side registered in advance, and the wireless communication unit 42 receives the connection information transmitted from the mobile terminal 5. If this is the case (Yes in the step of ST23), the communication connection with the mobile terminal 5 is permitted, and the terminal connection operation is terminated. Then, the stove operation is not performed, the communication with the mobile terminal 5 is possible, and the mobile terminal 5 is in use (the setting operation screen is displayed, or the setting operation screen is arranged). If the button is pressed within a predetermined time, etc.), the display form of the display units 41 and 47 is set to the power saving display mode with low power consumption (for example, all lights are turned off), and in this state. Monitors whether the stove power is turned off. Then, when the stove power supply is turned off, the stove power supply is turned off and the operation is terminated (ST28 to ST29, ST26 to ST27).

That is, after the stove power is turned on, the stove is operated, the connection information is transmitted from the mobile terminal 5, or when the mobile terminal 5 is used, the mobile terminal 5 is used. Steps from ST23 to ST26 until the power is turned off manually, assuming that the burners 21 and 31 are likely to be used, such as when the operating conditions are being set or when there is an intention to perform automatic cooking. Is repeated, and the automatic power off operation is not performed.

Although not shown, if the setting operation is completed on the mobile terminal 5 while monitoring whether the stove power is turned off and the setting operation is not performed for a certain period of time, or the setting operation screen is displayed. If the mobile terminal 5 is no longer in use, such as when it is turned off (No in the step of ST28), the setting of the power saving display mode is canceled because there is a possibility that the stove operation will be performed next. After returning the display units 41 and 47 to the standard display mode, it is monitored whether or not the stove power is turned off (ST26).

During the period from when the stove power is turned on until the fourth predetermined time S4 (for example, 120 seconds) elapses, the stove is not operated, the connection information is not transmitted from the mobile terminal 5, and the connection information is not transmitted. If the mobile terminal 5 is not used (No in the step of ST23, Yes in the step of ST30), the stove power is automatically turned off and the operation is terminated (ST27). Also, when the user manually turns off the stove power supply (Yes in the step of ST6), the stove power supply is turned off and the operation ends (ST27).

In this case, as in the above embodiment, there is a possibility that the burners 21 and 31 are used without communication with the mobile terminal 5 in the state where the stove power is turned on. If it is determined to be low (here, when communication with the mobile terminal 5 is not performed for the fourth predetermined time S4 or more, and the stove is not operated), the stove power is automatically turned off. Therefore, wasteful power consumption can be suppressed. Therefore, the battery life can be extended accordingly.

On the other hand, after the stove power is turned on, the stove is operated, the connection information is transmitted from the mobile terminal 5, or when the mobile terminal 5 is used, the mobile terminal 5 is used. If there is a high possibility that the burners 21 and 31 will be used, such as when the operation conditions are being set or when there is an intention to perform automatic cooking, the steps from ST24 to ST26 are executed and the automatic power off operation is performed. Since this is not done, the stove power supply is not automatically turned off during the operation of setting the operating conditions on the mobile terminal 5. Therefore, the usability is also significantly improved.

Moreover, in this case, as in the above embodiment, after the stove power is turned on, the display units 41 and 47 are changed to a display form with low power consumption while communication with the mobile terminal 5 is being performed. Since the switching is possible, the power consumption of the entire appliance can be suppressed even when the automatic power-off operation is not performed as described above. Therefore, the battery life can be extended accordingly.

In the above embodiment, a burner using the combustion exhaust gas of gas as a heat source has been described as a heating means for heating the object to be heated, but instead of the burner, radiant heat or conduction heat from the electric heating unit is used. An electric heater that heats the object to be heated may be used, an electromagnetic induction heater that heats the object to be heated by electromagnetic induction may be used, a burner, an electric heater, or an electromagnetic wave. Induction heaters may be used in combination.

As described above, the present invention is particularly useful for cooking cookers powered by batteries such as dry batteries and storage batteries, but can also be applied to cooking cookers powered by external power. Further, the present invention can be applied to a gas stove in which a heating means is provided only on the upper part of the main body, and can be applied to a grill device in which the heating means is provided only inside the main body.
