以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
（実施の形態１）
図１、図２は本発明の実施の形態１における誘導加熱調理器を示すものである。
(Embodiment 1)
1 and 2 show an induction heating cooker according to Embodiment 1 of the present invention.
図１、２に示すように、調理物を入れる容器１０のハンドル部１１にはＩＣタグ１２を内蔵している。ＩＣタグ１２には本実施の形態では容器１０の加熱上限電力情報（例えば２ｋＷ）が予め記憶されている。容器１０を加熱する誘導加熱調理器２０は、容器１０を誘導加熱する加熱コイル２１と、加熱コイル２１に高周波電流を印加する高周波電流発生手段２２と、容器１０を置く天板２３と、天板２３の下面に加熱コイル２１の外周の外側に加熱コイル２１の中心と中心がほぼ一致するようにループ状（本実施の形態では３回）に印刷したアンテナ２４と、アンテナ２４を介してＩＣタグ１２と通信を行うリーダ２５と、リーダ２５から得た信号により高周波発生手段２２を制御する制御手段２６とで構成している。なお、２７は金属でできた誘導加熱調理器の筐体である。なお、図２に示されている２４−１はアンテナ２４とリーダ２５を接続するためのリード線取付け用電極部で
ある。
As shown in FIGS. 1 and 2, an IC tag 12 is built in the handle portion 11 of the container 10 into which the food is put. In the present embodiment, heating upper limit power information (for example, 2 kW) of the container 10 is stored in the IC tag 12 in advance. The induction heating cooker 20 that heats the container 10 includes a heating coil 21 that induction-heats the container 10, high-frequency current generating means 22 that applies a high-frequency current to the heating coil 21, a top plate 23 on which the container 10 is placed, and a top plate An antenna 24 printed in a loop shape (three times in the present embodiment) so that the center of the heating coil 21 substantially coincides with the center of the outer periphery of the heating coil 21 on the lower surface of the heating coil 21, and an IC tag via the antenna 24 12 and a control unit 26 for controlling the high frequency generation unit 22 by a signal obtained from the reader 25. Reference numeral 27 denotes a casing of an induction heating cooker made of metal. Note that 24-1 shown in FIG. 2 is a lead wire attaching electrode portion for connecting the antenna 24 and the reader 25.
なお、本発明の実施の形態では、アンテナ２４は銀ペーストをスクリーン印刷することで構成している。 In the embodiment of the present invention, the antenna 24 is configured by screen-printing silver paste.
以上のように構成された誘導加熱調理装置について、以下その動作、作用を説明する。 About the induction heating cooking apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
まず、容器１０を天板２３に載せ、調理を開始する。高周波電流発生手段２２は加熱コイル２１に高周波電流を印加し、加熱コイル２１から放射された交番磁束により容器１０の底面に渦電流が発生し、容器１０の底面は加熱される。一方、リーダ２５によりアンテナ２４は高周波（ここでは１３．５６ＭＨｚ）を発信し、この高周波をＩＣタグ１２が受信し、ＩＣタグ１２はその高周波を整流、平滑して電源として利用する。ここで、２ｋＷを超える電力を印加しようとしても、ＩＣタグに保存された加熱上限電力情報（２ｋＷ）をアンテナ２４を介してリーダ２５が受信し、その信号が制御手段２６に入力されるため、制御手段２６が高周波電流発生手段２２を制御し、２ｋＷを超える電力が印加されることはない。 First, the container 10 is placed on the top plate 23 and cooking is started. The high frequency current generating means 22 applies a high frequency current to the heating coil 21, an eddy current is generated on the bottom surface of the container 10 by the alternating magnetic flux radiated from the heating coil 21, and the bottom surface of the container 10 is heated. On the other hand, the antenna 24 transmits a high frequency (here 13.56 MHz) by the reader 25, and the IC tag 12 receives this high frequency, and the IC tag 12 rectifies and smoothes the high frequency and uses it as a power source. Here, even if the power exceeding 2 kW is to be applied, the reader 25 receives the heating upper limit power information (2 kW) stored in the IC tag via the antenna 24 and the signal is input to the control means 26. The control means 26 controls the high-frequency current generating means 22 so that no electric power exceeding 2 kW is applied.
以上のように、本実施の形態によれば、アンテナ２４が加熱コイル２１の外周に設置されているために、容器１０のハンドル部１１が円周上のどの位置にあっても通信でき、使い勝手が良い。 As described above, according to the present embodiment, since the antenna 24 is installed on the outer periphery of the heating coil 21, communication is possible regardless of the position of the handle portion 11 of the container 10 on the circumference. Is good.
（参考の形態１）
次に、図３は、本発明の参考の形態１における誘導加熱調理器を示すものである。
(Reference form 1 )
Next, FIG. 3 shows an induction heating cooker in Reference Embodiment 1 of the present invention.
本参考の形態においては、容器１０の底部に底部中央までの穴部１３を設け、穴部１３には、温度検知素子１４が容器１０の底部中央まで挿入されている。なお、本参考の形態では、温度検知素子１４は白金センサーで構成している。温度検知素子１４はＩＣタグ１２と接続され、ＩＣタグ１２は温度検知素子１４が検知した容器１０の底部温度情報をアンテナに送信する。他の構成は実施の形態１と同様である。 In the present reference, a hole 13 to the bottom center in the bottom of the container 10 is provided, the hole 13, the temperature sensing element 14 is inserted to the bottom center of the container 10. In the present reference embodiment, the temperature sensing element 14 is constituted by a platinum sensor. The temperature detection element 14 is connected to the IC tag 12, and the IC tag 12 transmits the bottom temperature information of the container 10 detected by the temperature detection element 14 to the antenna. Other configurations are the same as those in the first embodiment.
以上のように構成された誘導加熱調理装置について、以下その動作、作用を説明する。 About the induction heating cooking apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.
まず、容器１０を天板１３に載せ、誘導加熱調理器２０の設定温度を例えば１８０℃に設定して調理を開始する。高周波電流発生手段２２は加熱コイル２１に高周波電流を印加し、加熱コイル２１から放射された交番磁束により容器１０の底面に渦電流が発生し、容器１０の底面は加熱される。一方、リーダ２５によりアンテナ２４は高周波（ここでは１３．５６ＭＨｚ）を発信し、この高周波をＩＣタグ１２が受信し、ＩＣタグ１２はその高周波を整流、平滑して電源として利用する。なお、容器１０が加熱されると、容器１０の底面に取付けられた温度検知手段１４の温度が上昇する。その結果温度検知手段１４の抵抗値が変化し、その抵抗値の変化をＩＣタグ１４はアンテナ２４を介してリーダ２５に送信する。リーダはその信号を制御手段２６に送る。制御手段２６はその信号と設定温度（例えば、１８０℃）を比較して、高周波電流発生手段２２の加熱コイル２１への高周波出力を制御し、容器１０の温度を１８０℃に保つ。 First, the container 10 is placed on the top plate 13, and the set temperature of the induction heating cooker 20 is set to 180 ° C., for example, and cooking is started. The high frequency current generating means 22 applies a high frequency current to the heating coil 21, an eddy current is generated on the bottom surface of the container 10 by the alternating magnetic flux radiated from the heating coil 21, and the bottom surface of the container 10 is heated. On the other hand, the antenna 24 transmits a high frequency (here 13.56 MHz) by the reader 25, and the IC tag 12 receives this high frequency, and the IC tag 12 rectifies and smoothes the high frequency and uses it as a power source. When the container 10 is heated, the temperature of the temperature detecting means 14 attached to the bottom surface of the container 10 increases. As a result, the resistance value of the temperature detecting means 14 changes, and the IC tag 14 transmits the change of the resistance value to the reader 25 via the antenna 24. The reader sends the signal to the control means 26. The control means 26 compares the signal with a set temperature (for example, 180 ° C.), controls the high frequency output to the heating coil 21 of the high frequency current generating means 22, and keeps the temperature of the container 10 at 180 ° C.
以上のように、本参考の形態によれば、容器１０の底の温度を底部に取付けた温度検知素子１４で直接検知するとともに、その信号を誘導加熱調理器に送り、その情報に基づき誘導加熱にて容器１０の底を直接加熱制御するために、精度の良い、しかも応答性の良い温度制御ができる。 As described above, according to this reference embodiment, with directly detected by a temperature sensing element 14 attached to a temperature of the bottom of the vessel 10 to the bottom, it sends the signal to the induction heating cooker, the induction heating on the basis of the information Since the bottom of the container 10 is directly heated and controlled, temperature control with high accuracy and responsiveness can be performed.
ところで、本発明の実施の形態では、アンテナは、銀ペーストをスクリーン印刷して構
成したが、カーボンペーストをスクリーン印刷することで構成するなど、導電性のペーストであれば良い。
By the way, in the embodiment of the present invention, the antenna is configured by screen-printing silver paste. However, the antenna may be any conductive paste, such as configured by screen-printing carbon paste.
また、本発明の実施の形態では、アンテナを中心が加熱コイル２１の中心とほぼ一致し、加熱コイル２１の外形よりも大きい円形としたが、加熱コイル２１と筐体２７の間のスペースに任意の形状で印刷しても良い。 In the embodiment of the present invention, the antenna has a circular shape whose center is substantially coincident with the center of the heating coil 21 and larger than the outer shape of the heating coil 21. You may print in the shape of.
以上のように、本発明にかかる誘導加熱調理器は、通信エラーの防止をすることが可能となるので、ビルトイン型および据え置き型の誘導加熱調理器の用途に適用できる。 As described above, since the induction heating cooker according to the present invention can prevent communication errors, it can be applied to built-in type and stationary type induction heating cookers.
