In recent years, a cooking device capable of communicating with an external terminal such as a smartphone has been developed. In such a heating cooker, when the power switch of the heating cooker is turned on, power is supplied from the power source of the heating cooker to the control unit, thereby enabling communication with the external terminal.

In addition, some of the current cookers have an ignition/extinguishing switch of the cooker that also serves as a power switch. In this configuration, when the ignition/extinguishing switch is turned on (that is, when the power switch is turned on), the stove burner of the heating cooker is ignited and power is supplied from the power source of the heating cooker to the control unit.

Here, in a heating cooker having both of the above two configurations (that is, a heating cooker that can communicate with an external terminal and whose ignition/extinguishing switch also serves as a power switch), the external terminal In order to communicate with the heating cooker, the ignition/extinguishing switch (ie, power switch) must be turned on. When the ignition/extinguishing switch is turned on, power is supplied from the power supply of the heating cooker to the control unit, thereby allowing the heating cooker to communicate with the external terminal. However, in such a heating cooker, turning on the ignition/extinguishing switch not only makes the heating cooker ready for communication with an external terminal, but also ignites the stove burner of the heating cooker. Although the purpose is to communicate with an external terminal and not to ignite the stove burner, turning on the ignition/extinguishing switch also ignites the stove burner. This can cause problems. For example, when the stove burner is ignited even though the user does not plan to start cooking, heating is started without permission, resulting in a problem that the food is not delicious.

This specification provides a technique that can prevent the start of heating when the purpose of the cooker is to communicate with an external terminal and not to heat an object to be heated.

The heating cooker disclosed in this specification includes a heating unit capable of heating an object to be heated, a communication unit capable of communicating with an external terminal, and a heating unit that receives a first operation for starting heating in the heating unit. an operation unit, a communication operation unit that receives a second operation for enabling communication in the communication unit, a heating control unit that controls the operation of the heating unit, and a communication control unit that controls the operation of the communication unit a power supply for supplying power to the heating control unit and the communication control unit; and the heating control unit and the communication control unit are connected in series to the power supply, and the first operation received by the heating operation unit. and a heating switch that is connected to the power source in series with the communication control unit, is connected to the power source in parallel with the heating control unit, and is received by the communication operation unit. A communication switch that is turned on in conjunction with the operation of 2 may be provided. In this heating cooker, when the heating operation unit receives the first operation, the heating unit starts heating, the heating switch is turned on, and power is supplied from the power source to the heating control unit. Then, the heating control unit becomes capable of controlling the operation of the heating unit, and power is supplied from the power source to the communication control unit, so that the communication control unit becomes capable of controlling the operation of the communication unit. may Further, when the communication operation unit receives the second operation while the heating switch is turned off, the communication is performed while the heating unit does not start heating and power is not supplied from the power source to the heating control unit. A switch may be turned on, power may be supplied from the power source to the communication control unit, and the communication control unit may be in a state of being able to control the operation of the communication unit.

According to this configuration, when the heating operation unit receives the first operation for starting heating in the heating unit, the heating unit starts heating. Further, when the heating operation unit receives the first operation, the heating switch is turned on in conjunction with it, power is supplied to the heating control unit, and the heating control unit can control the operation of the heating unit. become. Therefore, for example, the heating control unit can control the heating amount and heating time of the heating unit based on the automatic cooking program and recipe information, and automatic cooking can be executed. Further, when the heating switch is turned on, the power of the power supply is also supplied to the communication control section, and the communication control section becomes in a state of being able to control the operation of the communication section. Therefore, the cooking device can communicate with the external terminal, and for example, can receive recipe information for automatic cooking from the external terminal.

Further, according to the above configuration, when the communication operation unit accepts the second operation for enabling communication in the communication unit while the heating switch is turned off, the communication switch is turned on in conjunction therewith. Then, the power of the power source is supplied to the communication control unit, and the communication control unit becomes ready to control the operation of the communication unit. Therefore, the cooking device can communicate with the external terminal, and for example, can receive recipe information for automatic cooking from the external terminal. On the other hand, even if the communication switch is turned on, since the heating switch is in the off state, power from the power supply is not supplied to the heating control unit. Also, the heating unit does not start heating.

As described above, according to the above configuration, even if the communication operation unit accepts the second operation for enabling communication between the heating cooker and the external terminal, the heating unit does not start heating. Therefore, when the purpose of the heating cooker is to communicate with the external terminal and not to heat the object to be heated, the heating can be prevented from starting.

The heating control section may include a first storage section. The communication control section may include a second storage section. When the communication control unit receives information from the external terminal via the communication unit while the heating switch is in the off state and the communication switch is in the on state, the communication control unit converts the received information to the You may store in a 2nd memory|storage part. The heating control section may acquire the information stored in the second storage section and store the information in the first storage section when the heating switch is turned on.

According to the above configuration, the information received by the communication control unit from the external terminal is temporarily stored in the second storage unit when power is not supplied from the power source to the heating control unit (when the heating unit does not start heating). can be kept After that, when the heating switch is turned on and power is supplied to the heating control unit, the information received from the external terminal can be moved from the second storage unit to the first storage unit. Therefore, information can be reliably acquired from the external terminal.

The power source may be a dry battery. When the power source for supplying power to the heating control unit and the communication control unit of the heating cooker is a dry battery, it is desirable not to consume extra power because the power of the dry battery is limited. When the purpose of the heating cooker is to communicate with an external terminal and not to heat the object to be heated, power from the dry battery is not supplied to the heating control unit, thereby suppressing excessive power consumption. can. This technology is effective when the power source is dry batteries.

(Communication control side processing; Fig. 5)
Next, the communication control side processing executed in the cooking-by-heating system 1 will be described. The communication control-side processing shown in FIG. 5 is started when communication button 30 of heating cooker 10 receives an ON operation (when the user of heating cooker 10 performs an ON operation of communication button 30).

When the communication button 30 receives the ON operation, the communication switch 92 is turned ON (S10). When the communication switch 92 is turned on while the heating switch 90 is turned off, power supply to the communication control unit 82 is started. The power of the dry battery 34 is supplied to the communication control section 82 (see FIGS. 2 and 4). This enables the communication control unit 82 to control the operation of the BTI/F 86 . When the heating switch 90 is already turned on, the power of the dry battery 34 is already supplied to the communication control section 82 .

When the heating switch 90 is turned off, the electric power of the dry battery 34 is not supplied to the heating control section 72 (see FIGS. 2 and 4). When the heating switch 90 is off, the stove heating amount operation unit 61a does not receive the ignition operation. Therefore, heating is not started by the stove burner 12a.

In S12 following S10, the communication control unit 82 sets a timer for measuring the timing at which the communication switch 92 is turned off. The predetermined time set by the timer is, for example, 3 minutes.

In subsequent S14, the communication control unit 82 determines whether recipe information has been received from the external terminal 100 via the BTI/F86. If the recipe information has been received, the communication control unit 82 determines YES and proceeds to S16. Otherwise, the communication control unit 82 determines NO and proceeds to S22.

In subsequent S16, the communication control unit 82 determines whether or not the heating switch 90 is on. If the heating switch 90 is on, the communication control unit 82 determines YES and proceeds to S20. Otherwise, the communication control unit 82 determines NO and proceeds to S18.

In S20 after YES in S16, the communication control unit 82 stores the recipe information received in S14 in the first memory 74 provided in the heating control board 70 (see FIG. 2). That is, the communication control unit 82 stores the received recipe information in the first memory 74 when the power of the dry battery 34 is supplied to the heating control unit 72 . On the other hand, in S18 after NO in S16, the communication control unit 82 stores the recipe information received in S14 in the second memory 84 provided in the communication control board 80 (see FIG. 2). That is, the communication control unit 82 sends the received recipe information to the second Store in memory 84 .

In subsequent S22, the communication control unit 82 determines whether or not the predetermined time (for example, 3 minutes) set by the timer in S12 has elapsed. If the predetermined time has passed, the communication control unit 82 determines YES and proceeds to S24. Otherwise, the communication control unit 82 determines NO and returns to S14. The communication control unit 82 keeps the communication switch 92 ON until a predetermined time has passed.

In subsequent S24, the communication control unit 82 turns off the communication switch 92 . When the communication switch 92 is turned off, power from the dry battery 34 is no longer supplied to the communication control section 82 . From the above, the communication control side processing ends.

(Heating control side processing; Fig. 6)
Next, a description will be given of the heating control-side processing executed in the above-described heating cooker system 1. FIG. The heating control side process shown in FIG. 6 is started when the stove heating amount operation unit 61a receives an ignition operation (when the user of the heating cooker 10 executes the ignition operation of the stove heating amount operation unit 61a).

When the stove heating amount operation unit 61a receives an ignition operation, the stove burner 12a is ignited. Thereby, the heating of the object to be heated is started by the stove burner 12a. Further, when the stove heating amount operation unit 61a receives an ignition operation, the heating switch 90 is turned on (S30). When the heating switch 90 is turned on, power supply to the heating control section 72 and the communication control section 82 is started. Power from the dry battery 34 is supplied to the heating control section 72 and the communication control section 82 (see FIGS. 2 and 4). As a result, the heating control unit 72 becomes capable of controlling the operation of the stove burner 12a. Also, the communication control unit 82 becomes ready to control the operation of the BTI/F 86 . Note that when the communication switch 92 is already turned on, the power of the dry cell 34 is already supplied to the communication control section 82 .

In S32 following S30, the heating control section 72 determines whether or not recipe information is stored in the second memory 84 provided on the communication control board 80. FIG. If the communication control unit 82 stores the recipe information in the second memory 84 in S18 (see FIG. 5), the recipe information is stored in the second memory 84 . If recipe information is stored in the second memory 84, the heating control unit 72 determines YES and proceeds to S34. Otherwise, the heating control unit 72 determines NO and proceeds to S36.

In subsequent S<b>34 , the heating control section 72 acquires the recipe information stored in the second memory 84 and stores it in the first memory 74 . The heating control section 72 moves recipe information from the second memory 84 to the first memory 74 . The heating control section 72 can perform automatic cooking based on recipe information stored in the first memory 74 . The heating control unit 72 deletes the recipe information from the second memory 84 after moving the recipe information to the first memory 74 . After that, when the stove heating amount operation unit 61a receives a fire extinguishing operation, the heating switch 90 is turned off (S36). Also, the stove burner 12a is extinguished. From the above, the heating control side processing ends.

The heating cooker system 1 and the heating cooker 10 according to the embodiment have been described above. According to the above configuration, when the purpose of the heating cooker 10 is to communicate with the external terminal 100 and not to heat the object to be heated (for example, a pot), heating is not started. can be done. Further, if such a configuration is used for the grill burner 12d, even if the communication button 30 receives an ON operation for enabling communication between the heating cooker 10 and the external terminal 100 while the heating switch 90 is in an OFF state, Also, since heating is not started by the grill burner 12d, unintentional heating by the user of the cooking device 10 can be prevented from starting. If the grill burner 12d starts heating in spite of the intention to enable communication between the heating cooker 10 and the external terminal 100, a problem arises such that, for example, delicious food cannot be prepared. According to the configuration of (1), since unintended heating is not started, such a problem can be suppressed.

Further, in the above-described heating cooker 10, when the heating switch 90 is in the off state and the communication switch 92 is in the on state, the communication control unit 82 receives the recipe information from the external terminal 100 via the BTI/F 86. If received, the received recipe information is stored in the second memory 84 . When the heating switch 90 is turned on, the heating control section 72 acquires the recipe information stored in the second memory 84 and stores it in the first memory 74 . According to this configuration, the recipe information received from the external terminal 100 by the communication control section 82 when the power of the dry battery 34 is not supplied to the heating control section 72 can be temporarily stored in the second memory 84 . After that, when the heating switch 90 is turned on and the power of the dry battery 34 is supplied to the heating control section 72, the recipe information received from the external terminal 100 can be moved from the second memory 84 to the first memory 74. . Therefore, recipe information can be reliably acquired from the external terminal 100 .

Moreover, since the above-described heating cooker 10 uses the dry battery 34 as a power source, it is desirable not to consume extra power. In the above-described heating cooker 10, when the purpose is to communicate with the external terminal 100 and not to heat the object to be heated, only the communication button 30 is turned on so that the heating control unit 72 It is possible to communicate with the external terminal 100 in a state where the power of the dry battery 34 is not supplied. Therefore, consumption of extra power can be suppressed. This is particularly effective when the dry battery 34 is used as the power source.
