電源回路１７は、後述する給電コイル２３の電磁誘導作用によって受電コイル１４に例えば１００Ｖの電圧が発生すると、その電圧から操作／表示部１６及び制御回路１８の制御電圧を生成すると共に、蓋ヒータ１２及び胴ヒータ１３に１００Ｖの電圧を供給可能にする。制御回路１８には、白米、玄米など米の種類、各米に設定された炊き上がりの状態(硬めや柔らかめ）や、お粥や炊き込みなどに応じて加熱コイル２２、胴ヒータ１３及び蓋ヒータ１２を制御する運転モードが設定されている。この制御回路１８は、操作／表示部１６により炊飯メニューが選択されたときに、その炊飯メニューに応じた運転モードを選択して実行する。また、制御回路１８は、運転モードに基づいて加熱コイル２２の制御情報(電力制御)を生成し、制御情報を第１の通信回路１９から電波で送信し、後述する第２の通信回路２５に受信させる。   When a voltage of, for example, 100 V is generated in the power receiving coil 14 due to an electromagnetic induction effect of a power feeding coil 23 described later, the power supply circuit 17 generates a control voltage for the operation / display unit 16 and the control circuit 18 from the voltage, and the lid heater 12 In addition, a voltage of 100 V can be supplied to the body heater 13.

Receive.

誘導加熱調理器２１は、例えば外観が高さの低い直方体状に形成され、上部内面に配設された加熱コイル２２（誘導加熱手段）と、同一面に加熱コイル２２の中心軸を中心として加熱コイル２２の外周に配設された給電コイル２３と、電源回路２４と、調理器１の第１の通信回路１９に対向配置された第２の通信回路２５とを備えている。加熱コイル２２は、調理器１の底部に設けられた耐熱板４に対向するように配置され、給電コイル２３は、調理器１の底部に配設された受電コイル１４と磁気的に結合されるように配置されている。   The induction heating cooker 21 is formed in, for example, a rectangular parallelepiped shape whose appearance is low, and is heated around the central axis of the heating coil 22 on the same surface as the heating coil 22 (induction heating means) disposed on the upper inner surface. A power supply coil 23 disposed on the outer periphery of the coil 22, a power supply circuit 24, and a second communication circuit 25 disposed to face the first communication circuit 19 of the cooking device 1 are provided. The heating coil 22 is disposed so as to face the heat-resistant plate 4 provided at the bottom of the cooking device 1, and the power feeding coil 23 is magnetically coupled to the power receiving coil 14 disposed at the bottom of the cooking device 1. Are arranged as follows.

電源回路２４は、交流２００Ｖの電源と接続され、誘導加熱調理器２１に設けられた電源スイッチがオンされたときに給電コイル２３に２００Ｖの電圧を印加する電源部、加熱コイル２２に高周波電流を供給するための直流電源部及びインバータ部などを有している。第２の通信回路２５は、第１の通信回路１９からの電波が受信されると、制御回路１８によって生成された制御情報を受信電波から抽出し、そして、抽出した制御情報を電源回路２４のインバータ部に出力して駆動させる。   The power supply circuit 24 is connected to an AC 200V power supply, and when a power switch provided in the induction heating cooker 21 is turned on, a power supply unit that applies a voltage of 200V to the feeding coil 23 and a high frequency current to the heating coil 22. It has a DC power supply unit and an inverter unit for supply. When the radio wave from the first communication circuit 19 is received, the second communication circuit 25 extracts the control information generated by the control circuit 18 from the received radio wave, and extracts the extracted control information from the power supply circuit 24. Output to the inverter unit to drive.

次に、前記のように構成された加熱調理装置の動作を説明する。
誘導加熱調理器２１に調理器１を載置した後に、誘導加熱調理器２１の電源スイッチをオンすると、誘導加熱調理器２１の電源回路２４は、電源部を動作させて２００Ｖの電圧を給電コイル２３に印加し電流を流す。この時、電磁誘導作用により調理器１の受電コイル１４に１００Ｖの電圧が生成され、電源回路１７に印加される。この電源回路１７は、１００Ｖの電圧が印加されると、操作／表示部１６及び制御回路１８の制御電圧を生成してそれぞれに供給し、操作／表示部１６及び制御回路１８を動作可能にする。 Next, the operation of the cooking device configured as described above will be described.
After the cooking device 1 is placed on the induction heating cooker 21, when the power switch of the induction heating cooker 21 is turned on, the power supply circuit 24 of the induction heating cooker 21 operates the power supply unit to supply a voltage of 200V to the feeding coil. The current is applied to 23. At this time, a voltage of 100 V is generated in the power receiving coil 14 of the cooking device 1 by electromagnetic induction and is applied to the power supply circuit 17. When a voltage of 100 V is applied, the power supply circuit 17 generates and supplies control voltages for the operation / display unit 16 and the control circuit 18 to enable the operation / display unit 16 and the control circuit 18 to operate. .

この状態において、例えば、操作／表示部１６により白米を選択して炊飯開始のスイッチをオンすると、制御回路１８は、その炊飯メニューに応じた運転モードを選択して、その運転モードにおける予熱工程に入る。先ず、加熱コイル２２に連続通電させる制御情報を第１の通信回路１９に出力する。第１の通信回路１９は、入力された制御情報を電波によって誘導加熱調理器２１の第２の通信回路２５に送信する。第２の通信回路２５は、電波が受信されると受信電波から制御情報を抽出し、抽出した制御情報を電源回路２４のインバータ部に出力して駆動させる。これにより、加熱コイル２２に２００Ｖの電圧が印加され高周波電流が流れる。つまり、調理器１側の制御回路１８により設定された所定電力が加熱コイル２２から連続的に出力されるようにする。   In this state, for example, when white rice is selected by the operation / display unit 16 and the rice cooking start switch is turned on, the control circuit 18 selects an operation mode corresponding to the rice cooking menu and performs the preheating process in the operation mode. enter. First, control information for continuously energizing the heating coil 22 is output to the first communication circuit 19. The first communication circuit 19 transmits the input control information to the second communication circuit 25 of the induction heating cooker 21 by radio waves. When the radio wave is received, the second communication circuit 25 extracts control information from the received radio wave, and outputs the extracted control information to the inverter unit of the power supply circuit 24 for driving. Thereby, a voltage of 200 V is applied to the heating coil 22 and a high frequency current flows. That is, the predetermined power set by the control circuit 18 on the cooking device 1 side is continuously output from the heating coil 22.

調理器１の制御回路１８は、予熱工程開始からの経過時間が所定時間に達したかどうか、容器温度センサ６の検出温度が予熱温度に達したか否かを判定しており、容器温度センサ６の検出温度が予熱温度に達したときに加熱コイル２２に間欠通電させる制御情報を第１の通信回路１９から第２の通信回路２５に送信する。第２の通信回路２５は、受信電波から制御情報を抽出して電源回路の２４のインバータ部に出力し加熱コイル２２の通電を間欠的に行わせ、容器温度センサ６の検出温度が予熱温度を保持するようにする。一方、調理器１の制御回路１８は、前述したように予熱工程開始からの経過時間が所定時間に達したかどうかを判定しており、経過時間が所定時間に達したとき炊飯工程に移行する。   The control circuit 18 of the cooking device 1 determines whether the elapsed time from the start of the preheating process has reached a predetermined time, whether the temperature detected by the container temperature sensor 6 has reached the preheating temperature, and the container temperature sensor. When the detected temperature 6 reaches the preheating temperature, control information for intermittently energizing the heating coil 22 is transmitted from the first communication circuit 19 to the second communication circuit 25. The second communication circuit 25 extracts control information from the received radio wave and outputs it to the inverter section 24 of the power supply circuit to intermittently energize the heating coil 22, and the temperature detected by the container temperature sensor 6 sets the preheating temperature. Try to keep. On the other hand, the control circuit 18 of the cooking device 1 determines whether or not the elapsed time from the start of the preheating process has reached a predetermined time as described above, and shifts to the rice cooking process when the elapsed time reaches the predetermined time. .

調理器１の制御回路１８は、炊飯工程に入ると、予熱工程時より電力が高くなるように電流を上げ、調理容器３の温度が異常上昇しないように間欠通電させる制御情報を第１の通信回路１９から第２の通信回路２５に送信する。第２の通信回路２５は、その制御情報を電源回路２４のインバータ部に出力して、加熱コイル２２の通電を間欠的に行わせる。この時、制御回路１８は、電源回路１７を動作させ１００Ｖの電圧を胴ヒータ１３と蓋ヒータ１２に印加し電流を流す。胴ヒータ１３で調理容器３の側面を加熱することにより被加熱物である米を均一にふっくらと炊き上げることができる。また、蓋ヒータ１２で内蓋８を加熱することにより内蓋８に付着する結露をなくすことができ、調理容器３内の温度を高温に保つことができる。   When entering the rice cooking process, the control circuit 18 of the cooking device 1 increases the current so that the power is higher than that during the preheating process, and the control information for intermittently energizing the cooking container 3 so that the temperature of the cooking container 3 does not rise abnormally is the first communication. The signal is transmitted from the circuit 19 to the second communication circuit 25. The second communication circuit 25 outputs the control information to the inverter unit of the power supply circuit 24 so that the heating coil 22 is energized intermittently. At this time, the control circuit 18 operates the power supply circuit 17 to apply a voltage of 100 V to the trunk heater 13 and the lid heater 12 to flow current. By heating the side surface of the cooking vessel 3 with the body heater 13, the rice that is the object to be heated can be cooked uniformly and plumply. Moreover, the condensation which adheres to the inner lid 8 can be eliminated by heating the inner lid 8 with the lid heater 12, and the temperature in the cooking vessel 3 can be kept high.

その後、制御回路１８は、調理容器３２内の被加熱物が沸騰温度に達したかどうかを蓋温度センサ７の検出温度から判定し、蓋温度センサ７の検出温度が沸騰温度に達したときは、高温沸騰加熱工程に移行して、調理容器３の被加熱物が沸騰維持可能な所定温度以上になるように連続通電させる制御情報を第１の通信回路１９から第２の通信回路２５に送信し、時間の計測を開始する。第２の通信回路２５は、その制御情報を電源回路２４のインバータ部に出力して、加熱コイル２２の通電を連続的に行わせる。一方、制御回路１８は、前述の計測時間が高温沸騰時間を経過したかどうかを判定し、計測時間が高温沸騰時間を経過していないときは、前述した連続通電を継続させる。   Thereafter, the control circuit 18 determines whether or not the object to be heated in the cooking container 32 has reached the boiling temperature from the temperature detected by the lid temperature sensor 7, and when the temperature detected by the lid temperature sensor 7 has reached the boiling temperature. Then, the process proceeds to the high-temperature boiling heating process, and the control information for continuously energizing the heated object in the cooking container 3 so as to reach a predetermined temperature or higher at which boiling can be maintained is transmitted from the first communication circuit 19 to the second communication circuit 25. And start measuring time. The second communication circuit 25 outputs the control information to the inverter unit of the power supply circuit 24 so that the heating coil 22 is energized continuously. On the other hand, the control circuit 18 determines whether or not the above-described measurement time has passed the high-temperature boiling time, and when the measurement time has not passed the high-temperature boiling time, continues the above-described continuous energization.

また、制御回路１８は、計測時間が高温沸騰時間を経過したことを検知すると、調理容器３の被加熱物が沸騰維持可能な温度まで下げる連続通電の制御情報を第１の通信回路１９から第２の通信回路２５に送信する。第２の通信回路２５は、その制御情報を電源回路２４のインバータ部に出力して、加熱コイル２２の通電を連続的に行わせる。また、制御回路１８は、沸騰維持制御中に米の吸水糊化と蒸発により炊飯水がなくなるドライアップ温度に達したかどうかを蓋温度センサ７の検出温度から判定し、ドライアップ温度に達していないときは、前述した沸騰維持制御を行い、ドライアップ温度を検出したときは、蒸らし工程に入って電流を下げた間欠通電の制御情報を第１の通信回路１９から第２の通信回路２５に送信して、加熱コイル２２に制御情報に基づく間欠通電を行わせる。この時、制御回路１８は、蒸らし工程の時間が経過したかどうかを判定し、蒸らし工程の時間が経過したときに加熱コイル２２への通電を停止させる情報を第１の通信回路１９から第２の通信回路２５に送信して、要理容器３の誘導加熱を終了させる。また、電源回路の動作を停止して胴ヒータ１３と蓋ヒータ１２への通電を停止する。   Further, when the control circuit 18 detects that the high temperature boiling time has passed, the control circuit 18 sends the control information for continuous energization from the first communication circuit 19 to lower the temperature of the heated object in the cooking container 3 to a temperature at which boiling can be maintained. 2 to the communication circuit 25. The second communication circuit 25 outputs the control information to the inverter unit of the power supply circuit 24 so that the heating coil 22 is energized continuously. Further, the control circuit 18 determines whether or not the dry-up temperature at which the rice cooking water disappears due to the water absorption gelatinization and evaporation of the rice during the boiling maintenance control is determined from the detection temperature of the lid temperature sensor 7, and has reached the dry-up temperature. If not, the boiling maintenance control described above is performed, and when the dry-up temperature is detected, control information for intermittent energization that has entered the steaming process and reduced the current is transferred from the first communication circuit 19 to the second communication circuit 25. The heating coil 22 is intermittently energized based on the control information. At this time, the control circuit 18 determines whether or not the time of the steaming process has elapsed, and when the time of the steaming process has elapsed, information for stopping the energization of the heating coil 22 from the first communication circuit 19 to the second. To the communication circuit 25, and the induction heating of the basic container 3 is terminated. Further, the operation of the power supply circuit is stopped, and the energization to the trunk heater 13 and the lid heater 12 is stopped.

以上のように実施の形態１によれば、調理器１には加熱コイル及び加熱コイルに通電する電源回路が備えられていないので、調理器を軽量化でき、そのため、持ち運びが容易になっている。また、調理器１は２００Ｖを電源とする誘導加熱調理器２１によって加熱されるようにしているので、強い火力で調理することができる。   As described above, according to the first embodiment, since the cooking device 1 is not provided with the heating coil and the power supply circuit for energizing the heating coil, the cooking device can be reduced in weight, and thus is easy to carry. . Moreover, since the cooking appliance 1 is made to heat with the induction heating cooking appliance 21 which uses 200V as a power supply, it can cook with strong firepower.

また、調理器１に設けられた胴ヒータ１３と蓋ヒータ１２の電源を、誘導加熱調理器２１に搭載された給電コイル２３に磁気的に結合された受電コイル１４に生成される電圧とし、誘導加熱調理器２１に設けられた加熱コイル２２で調理器１内の調理容器３を誘導加熱するようにしたので、調理器１を誘導加熱調理器２１に載せるだけで簡単に調理を開始することが可能になり、調理器１の構成が従来の炊飯器と比べシンプルとなり、また、電源コードが不要であるため、水回りで使用したとしても電源コードを這って水が侵入することが無くなり、このため、水によるショートを起こすということが無く、発火する危険性を防止することができる。   Further, the power of the body heater 13 and the lid heater 12 provided in the cooking device 1 is set to a voltage generated in the power receiving coil 14 magnetically coupled to the power feeding coil 23 mounted on the induction heating cooking device 21, and induction is performed. Since the cooking container 3 in the cooking device 1 is induction-heated by the heating coil 22 provided in the heating cooking device 21, cooking can be started simply by placing the cooking device 1 on the induction heating cooking device 21. It becomes possible, and the configuration of the cooker 1 is simpler than that of the conventional rice cooker, and since no power cord is required, even if it is used around water, there is no intrusion of water through the power cord. Therefore, there is no short circuit caused by water, and the risk of fire can be prevented.

調理器１に操作／表示部１６を設けて運転モード選択できるようにしているので、誘導加熱調理器２１の操作／表示部をシンプルにすることができる。   Since the operation / display unit 16 is provided in the cooking device 1 so that the operation mode can be selected, the operation / display unit of the induction heating cooker 21 can be simplified.

また、第１の通信回路１９から第２の通信回路２５に制御情報を送信する際、電波を用いて制御情報を送るようにしたので、水や具材のこぼれによる回路の故障を防止することができる。   In addition, when transmitting control information from the first communication circuit 19 to the second communication circuit 25, the control information is transmitted using radio waves, so that failure of the circuit due to spillage of water or ingredients can be prevented. Can do.
