  By the way, when the wireless communication function between the gas stove 1 and the portable terminal 5 is used, the portable terminal 5 to be used needs to be registered in the gas stove 1 in advance. The procedure will be described in detail. First, on the portable terminal 5 side, a remote operation application program (hereinafter referred to as “stove operation AP” for setting operation conditions such as display of the operating state of the gas stove 1 and recipe data for automatic cooking is provided. "). Thereby, the operation display panel 61 of the portable terminal 5 is used for setting a cooking mode setting button serving as a pseudo operation key for selecting and setting a plurality of cooking modes such as boiling water, boiled food, deep-fried food, and rice cooking, and a heating target temperature. Temperature setting button to be a simulated operation key, thermal power setting button to be a simulated operation key for setting thermal power, timer setting button to be a simulated operation key to set heating time, setting of heating target temperature, thermal power, and heating time An adjustment button that becomes a pseudo operation key for adjusting the temperature, a connection button that becomes a pseudo operation key for enabling communication with the gas stove 1, and a pseudo operation key for changing the setting of the portable terminal 5 A setting operation screen on which setting change buttons and the like are arranged is displayed, and the automatic cooking operation condition selection setting and the communication setting with the gas stove 1 are enabled.

  Then, after the setting change button displayed on the operation display panel 61 is pressed and the communication setting mode is selected, the terminal information transmission button displayed on the operation display panel 61 is pressed. Sent to.

  On the other hand, on the gas stove 1 side, the operation for selecting the terminal registration mode with the setting input switch 46 (for example, the operation of selecting the “terminal registration mode” with the addition / subtraction switch after pressing the setting change switch with the stove power supply turned on) )I do. Thereby, the search for terminal information by the wireless communication unit 42 is started. That is, monitoring of whether or not terminal information is transmitted from the mobile terminal 5 is started. 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 has been registered successfully is wirelessly communicated. It transmits to the portable terminal 5 from the part 42, and complete | finishes registration operation | movement.

  As described above, 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 necessary for the transmission is automatically transmitted from the mobile terminal 5 and the terminal connection operation (pairing) is performed, so that communication with the mobile terminal 5 is possible. On the other hand, if the terminal information is not normally received by the wireless communication unit 42 even after a certain time has elapsed since the search for the terminal information is started, the registration operation is stopped as a time error.

  When the mobile terminal 5 is ready to communicate with the gas stove 1, when operating conditions selected and set by the cooking mode button, timer setting button, etc. are transmitted to the gas stove 1, the operation is performed after setting the operating conditions. 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 supply is turned on will be described according to the flowchart shown in FIG.

  When the stove power supply is turned on by the power switch 43, the power required for the operation of the entire gas stove 1 is supplied from a dry battery (not shown) to the stove control circuit 15. That is, the stove power supply is turned on (ST1 to ST2). Although not shown, when the stove power supply 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. That is, the display units 41 and 47 are set to a standard display form.

  If the stove power source is turned on, a search is performed as to whether or not connection information is transmitted from the pre-registered mobile terminal 5 for a predetermined time (for example, 5 seconds) (ST3). At this time, when 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 step ST3), the search is stopped and the burners 21 and 31 Whether the ignition operation, the heating power adjustment operation, the setting input switch 46 setting operation (hereinafter collectively referred to as “stove operation”) has not been performed for a first predetermined time S1 (for example, 120 seconds) or more, and the power switch At 43, monitoring of whether or not the stove power supply is turned off is started (ST4 to ST6).

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

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

  When the registered mobile terminal 5 is manually connected to the gas stove 1 by wireless, connection information necessary for communication with the gas stove 1 is transmitted from the mobile terminal 5 by pressing the connection button. And if the connection information received by the gas stove 1 side is recognized as the thing of the portable terminal 5 registered previously, communication connection with the portable terminal 5 will be permitted.

  When communication with the portable terminal 5 is possible, the automatic power-off operation described in 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), 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 portable terminal 5 has been used may be made based on 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 step ST9), the process returns to the step ST3 (if the state is set to the power saving display mode described later, it is saved). After canceling the setting of the power display mode, it is confirmed whether or not the communication connection with the portable terminal 5 is maintained (ST10, ST3). At this time, the stove operation AP is terminated on the mobile terminal 5 side, the communication with the mobile terminal 5 is interrupted due to poor communication, the power of the mobile terminal 5 is turned off, etc. If the communication connection is canceled (No in step ST3), 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 portable terminal 5 is used within the second predetermined time S2 (Yes in step ST8), the display form of the display units 41 and 47 is changed to the power saving display mode with low power consumption. (Here, all lights are turned off) (ST11). In the power saving display mode, the illuminance may be reduced or the display information may be reduced. Further, 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 is turned off, illuminance reduction, Display information may be restricted.

  If the stove operation is performed after the display form of the display units 41 and 47 is set to the power saving display mode in step ST11, the setting of the power saving display mode is canceled and the display units 41 and 47 are set as standard. To the display form (here, all lights up), and the process returns to the step ST3 (ST12, ST10, ST3). At this time, if the communication connection with the portable terminal 5 is released (No in step ST3), the automatic power-off function is enabled again.

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

  According to the gas stove 1, it is determined that communication with the portable terminal 5 is not performed and the possibility that the burners 21 and 31 are used is low when the stove power source is turned on. In this case (here, when the communication with the portable terminal 5 is not performed and the stove operation is not performed for the first predetermined time S1 or more), the stove power supply is automatically turned off. Power consumption can be suppressed. Therefore, the battery life can be extended accordingly.

  On the other hand, when communication is performed with the portable terminal 5 in a state where the stove power source is turned on, the automatic power source is used regardless of whether or not the burners 21 and 31 are likely to be used. Since the off operation is not performed, the stove power supply is not automatically turned off during the operation condition setting operation or the like on the mobile terminal 5. Therefore, usability is also greatly improved.

  Moreover, according to the gas stove 1, after the stove power is turned on, while the portable terminal 5 is being used, that is, while communication is being performed with the portable terminal 5, the display unit 41, 47 is switched to a display mode with low power consumption, so that 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, when communication with the portable 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 operation is automatically performed. Although what was comprised so that a stove power supply might be turned off was provided, it is provided with the person detection sensor which detects the presence or absence of the person of the front 13 side of the gas stove 1, and communication is not performed between the portable terminals 5 In this case, if the person is not present on the front surface 13 side of the stove 1 for a third predetermined time S3 (for example, 180 seconds) or longer, the stove power supply may be automatically turned off. In this case, when communication with the portable terminal 5 is not performed, if there is no user in front of the gas stove 1, the stove power supply is automatically turned off, so power consumption is appropriately suppressed. can do. Further, since there is no inconvenience that the stove power supply is automatically turned off despite the presence of the user in front of the gas stove 1 for the purpose of using the burners 21 and 31, the usability is further improved.

  Alternatively, a ventilation state determination unit that determines an operation state of the ventilation device installed above the gas stove 1 is provided, and if communication is not performed with the portable terminal 5, if the ventilation device is stopped, automatic The stove power supply may be configured to be turned off. In this case, when communication with the portable terminal 5 is not performed, the stove power supply is automatically turned off when the ventilator is stopped. it can. In addition, when the burners 21 and 31 are extinguished and cooking is temporarily interrupted, there is no inconvenience that the stove power supply is automatically turned off, so the usability is further improved.

  Moreover, in the said embodiment, when communication is performed between the portable terminals 5, the burners 21 and 31 can be used regardless of whether or not the burners 21 and 31 are likely to be used. Although it has been described that it is configured not to perform sex determination (steps ST4 to ST5), when communication with the mobile terminal 5 is performed, an operation condition setting operation is performed on the mobile terminal 5 It is assumed that the burner 21 or 31 is likely to be used because there is a case where the burner 21 or 31 is willing to perform automatic cooking, and the automatic power-off operation is not performed. Good.

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

  If the stove power source is turned on, whether the stove operation has been performed, whether the connection information has been transmitted from the mobile terminal 5 registered in advance, and communication with the mobile terminal 5 has already been performed. The monitoring of whether or not the portable terminal 5 is being used (for example, whether or not the setting operation screen is displayed) is started (ST23).

  Thereafter, when a stove operation is performed (Yes in ST23, Yes in ST24), the display units 41 and 47 are maintained in the above-described standard display mode (in a state set to the power saving display mode). For example, the setting of the power saving display mode is canceled), and the power switch 43 monitors whether or not the stove power supply is turned off. When the stove power supply is turned off, the stove power supply is turned off and the operation is terminated (ST24 to ST27).

  On the other hand, when the stove power source is turned on, the stove operation AP is activated on the pre-registered mobile terminal 5 side, and the wireless communication unit 42 receives the connection information transmitted from the mobile terminal 5. If so (Yes in step ST23), the communication connection with the portable terminal 5 is permitted, and the terminal connection operation is terminated. Then, the stove operation is not performed, and communication with the mobile terminal 5 is enabled, and the mobile terminal 5 is in use (a state in which the setting operation screen is displayed or any of the settings on the setting operation screen) If the button is pressed within a predetermined time), the display form of the display units 41 and 47 is set to a power saving display mode with low power consumption (for example, all off), and in this state Monitors whether the stove power supply has been turned off. 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 operation is performed, the connection information is transmitted from the mobile terminal 5, or the mobile terminal 5 is used when the mobile terminal 5 is used. ST23 to ST26 until the power is manually turned off, assuming that there is a high possibility that the burners 21 and 31 are used, for example, when the operation conditions are being set or when there is an intention to perform automatic cooking. Repeatedly, the automatic power off operation is not performed.

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

  Between the time when the stove power source is turned on and the fourth predetermined time S4 (for example, 120 seconds) has passed, no stove operation is performed, connection information is not transmitted from the portable terminal 5, and If the portable terminal 5 is not used (No in step ST23, Yes in step ST30), the stove power supply is automatically turned off and the operation is terminated (ST27). Also, when the user manually turns off the stove power (Yes in step ST6), the stove power is turned off and the operation ends (ST27).

  In this case, similarly to the above embodiment, there is a possibility that communication with the portable terminal 5 is not performed and the burners 21 and 31 are used in a state where the stove power source is turned on. If it is determined to be low (here, the communication with the portable terminal 5 is not performed for the fourth predetermined time S4 or more and the stove operation is not performed), the stove power supply is automatically turned off. Therefore, 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, the stove operation is performed, the connection information is transmitted from the portable terminal 5, or the portable terminal 5 is used when the portable terminal 5 is used. If it is highly likely that the burners 21 and 31 will be used, such as when operating conditions are being set or when there is an intention to perform automatic cooking, the steps ST24 to ST26 are executed, and the automatic power-off operation is performed. Since it is not performed, the stove power supply is not automatically turned off while the operation condition setting operation or the like is being performed on the mobile terminal 5. Therefore, usability is also greatly 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 mode with less power consumption during communication with the portable terminal 5. Since the switching is performed, the power consumption of the entire instrument 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, as the heating means for heating the object to be heated, a burner using gas combustion exhaust gas as a heat source has been described, but instead of the burner, by radiant heat or conduction heat from the electric heating section. An electric heater for heating an object to be heated may be used, an electromagnetic induction heater for heating an object to be heated by electromagnetic induction may be used, a burner, an electric heater, an electromagnetic An induction heater may be used in combination.

  As described above, the present invention is particularly useful for a cooking device that uses a battery such as a dry battery or a storage battery as a power source, but is also applicable to a cooking device that uses external power as a power source. The present invention can also be applied to a gas stove provided with heating means only at the upper part of the main body, and can also be applied to a grill device provided with heating means only inside the main body.
