Description

【０００１】
【発明の属する技術分野】
本発明は、電磁誘導加熱を利用した加熱調理器に係り、さらに詳しくは、１台の加熱調理器で炊飯と煮物等の他の調理を同時に行うことのできる加熱調理器に関するものである。
【０００２】
【従来の技術】
従来の誘導加熱調理器に、電磁誘導加熱装置と炊飯器本体とを分離可能とし、炊飯器の加熱装置として使用する場合は、電磁誘導加熱装置の上に炊飯器本体を位置させ、その突起に炊飯器本体に設けた嵌合凹部を嵌合して載置し、誘導加熱コイルに通電して炊飯器本体を加熱することにより炊飯し、煮物等の他の加熱装置として利用する場合は、電磁誘導加熱装置から炊飯器本体を取外して電気的接続を遮断し、電磁誘導加熱装置の上に別の調理を目的とする鍋等を載置して調理を行うようにしたものがある（例えば、特許文献１参照）。
【０００３】
また、加熱調理器のプレートの前部側下部に独立した２つの加熱コイルからなる誘導加熱部を設けると共に、後部側下面にヒータ加熱部を設け、プレート上に複数の調理鍋等を載置して電磁誘導加熱又はヒータ加熱により調理するようにしたものがある（例えば、特許文献２参照）。

【特許文献２】
特開平６−３３８３８４号公報（第４頁−第５頁、図４−図５）
【０００５】
【発明が解決しようとする課題】
特許文献１に記載の炊飯器は、炊飯器本体を電磁誘導加熱装置に載置する際に、その嵌合凹部を突起に嵌合するようにしているが、嵌合凹部が炊飯器本体の底面に設けられているためわかりにくく、位置決めが面倒である。また、電磁誘導加熱装置には誘導加熱コイルが１つしか設けられていないため、炊飯と他の調理を同時に行うことができない。さらに、炊飯以外の他の食材の調理を行う場合は、その都度電磁誘導加熱装置から炊飯用鍋を取外すと共に電気的接続を取外し、他の食材が入れられた汎用の鍋等を電磁誘導加熱装置上に載置しなければならないので、きわめて面倒であった。
【０００６】
また、特許文献２に記載の加熱調理器は、食材が入れられた複数の調理鍋等を同時にプレート上に載置して調理を行うことができるが、誘導加熱部には保温付きの炊飯モード回路が設けられていないので、この加熱調理器で自動的に炊飯を行うことができない。このため、別に設けた炊飯器により炊飯及び保温を行わなければならなかった。
【０００７】
本発明は、上記の課題を解決するためになされたもので、１台の加熱調理器に複数の加熱部を有し、少なくともその１つに調理物が沸騰後自動的に所定温度に保温される保温モード回路を設けることにより、炊飯と煮物その他の調理を同時に行うことができ、かつ保温性を向上することのできる加熱調理器を提供することを目的としたものである。
【０００８】
【課題を解決するための手段】
本発明に係る加熱調理器は、天面にトッププレートを有し、内部に複数の加熱部、該加熱部の出力等をそれぞれ制御する制御部等が設けられ、外部に前記制御部を個別に制御する複数のメニュースイッチ等を有する操作部が設けられて、流し台等に載置又は組込まれる加熱調理器において、前記制御部の少なくとも１つに、調理物の沸騰後に保温に移行する保温モード回路を設け、前記操作部に前記保温モード回路を制御するスイッチを設けると共に、前記複数のメニュースイッチを同時に操作しうるようにしたものである。
【０００９】
【発明の実施の形態】
［実施の形態１］
図１は加熱調理器を流し台に組込んで調理器等を載置した状態を示す本発明の実施の形態１に係る加熱調理器の斜視図、図２は図１の加熱調理器の斜視図、図３は図１の調理器部分の断面図、図４は図１の調理鍋部分の断面図である。
【００１０】
流し台７０に組込まれた加熱調理器１の本体ケース２の上面には、例えば板ガラスの如き非磁性材からなるトッププレート３が支持枠４により周囲が支持されて取付けられており、トッププレート３の上面には、後述の調理器３０（以下の説明では炊飯器という）を載置するリング状の載置部５ａ及び磁性材からなり通常の調理を行う鍋やフライパンなど６０ａ，６０ｂ（以下の説明では調理鍋という）を載置するリング状の載置部５ｂ，５ｃが印刷されている。そして、各載置部５ａ〜５ｃの近傍には、後述の加熱部２０ａ，２０ｂ，２０ｃの火力を表示し、また、必要に応じて炊飯や調理のスタート時刻や残り時間を表示する予約タイマーの表示部６ａ，６ｂ，６ｃが設けられている。
【００１１】
図には、載置部５ａ〜５ｃを３個設けた場合を示したが２個以上であればよく、その配置も図示のものに限定するものではない。また、炊飯器３０の載置部５ａをトッププレート３の後部側（奥側）に設けた場合を示したが、これに限定するものではなく、トッププレート３の前部側（手前側）に設けてもよい。しかし、調味料を入れたり、調理物をかき混ぜたりする通常の調理鍋６０ａ，６０ｂの載置部５ｂ，５ｃは、手前側に設けた方が使い勝手がよく、便利である。
【００１２】
７はハンドル７ａを有し、本体ケース２の前面側の一方の側に設けた引出し式のロースタである。８はロースタ７に隣接して設けられた主操作部で、電源を開閉するメインスイッチ９、各加熱部２０ａ〜２０ｃやロースタ７等へ通電するための炊飯スイッチ１０ａ、煮物スイッチ１０ｂ、調理スイッチ１０ｃ、１０ｄ、ロータスイッチ１０ｅ等のメニュースイッチ群１０及び表示部１１等が設けられている。
また、支持枠４の前面側には、各載置部５ａ〜５ｃに対応して、例えば火力（大、中、小等）の選択スイッチや予約タイマースイッチ等を有する補助操作部１２が設けられている。なお、これら主操作部８及び補助操作部１２の各スイッチ等の配置は一例を示すもので、適宜変更することができる。１３ａ，１３ｂは支持枠４の後面側に設けられた吸気口である。なお、吸気口１３ａ，１３ｂの一方を排気口にしてもよい。
【００１３】
１４は吸気口１３ａ，１３ｂの間（炊飯器３０の載置部５ａの近傍）に設けられて炊飯器３０を位置決めするガイド部で、所定の間隔で立設された一対のガイド壁１５ａ，１５ｂと、ガイド壁１５ａ，１５ｂの間に設けられた開口部１６とからなっている。なお、図にはガイド部１４のガイド壁１５ａ，１５ｂの前端部がトッププレート３上に突出した場合を示してあるが、支持枠４上のみに設けてもよく、その位置も図示の位置に限定するものではなく、炊飯器３０の載置部の近傍であればよい。
【００１４】
トッププレート３に設けた炊飯器３０及び調理鍋６０ａ，６０ｂの載置部５ａ〜５ｃの下には、トッププレート３の下面側において、コイル台２１に渦巻状に巻かれた誘導加熱コイル２２が設置された炊飯器３０の加熱部２０ａ、調理鍋６０ａ，６０ｂの加熱部２０ａ，２０ｂがそれぞれ設けられており、各加熱部２０ａ〜２０ｃの中心部には、トッププレート３の下面に当接して、その上に載置された炊飯器３０の内鍋３４や調理鍋６０ａ，６０ｂの温度を検出する温度センサ２３が設けられている。なお、炊飯器３０の加熱部２０ａ以外の加熱部２０ｂ，２０ｃは、その全部又は一部を誘導加熱コイル２２に代えてヒータを設けてもよい。
【００１５】
２５ａは炊飯器３０の加熱部２０ａの制御回路やタイマー回路２６（図８参照）等が設けられた制御部、２５ｂ，２５ｃは調理鍋６０ａ，６０ｂの加熱部２０ｂ，２０ｃの制御回路路やタイマー回路２６等が設けられた制御部で、炊飯用の制御部２５ａには、米又はその他の調理物を沸騰させたのち所定の温度状態に保つ保温モード回路である保温付き炊飯モード回路及び必要に応じて保温付き煮物モード回路が設けられている。なお、図には各加熱部２０ａ〜２０ｃごとにそれぞれ制御部２５ａ〜２５ｃを設けた場合を示したが、１枚のプリント基板に、炊飯用、煮物用及び調理用の各制御回路等をそれぞれ設けた１台の制御部で構成してもよい。２８は加熱部２０ａ〜２０ｃ、制御部２５ａ〜２５ｃ等を冷却する冷却用の送風機で、吸気口１３ａ，１３ｂから外気を吸引し、本体ケース２の外壁に設けた排気口（図示せず）から排出する。
【００１６】
調理器である炊飯器３０は、図３、図５に示すように、非磁性材からなり、上下が開口したほぼ筒状の内壁３２及び空間部を介して内壁３２の外周を囲繞する外壁３３とからなる調理容器３１と、磁性材からなり、上端部外周にフランジ３４ａを有する有底筒状の内鍋３４とを有し、内鍋３４は調理容器３１内に挿脱自在に収納されてそのフランジ３４ａが調理容器３１の上端部３２ａに係止し、その底面３４ｂは調理容器３１の下端部から露出してトッププレート３との間にすき間ｇを形成する。
【００１７】
調理容器３１の内壁３２の下部外周には、補助加熱体である誘導加熱コイルからなる底側面加熱体３５が積層して設けられており、また、上部には補助加熱体であるヒータからなる上側面加熱体３６が設けられている。なお、内鍋３４の温度を検出するために、その底面３４ｂに対応してトッププレート３の下面に当接する温度センサ２３を設けた場合を示したが、図３に破線で示すように、内鍋３４の側壁に当接する温度センサ２３ａをバネ等２３ｂにより出没自在に付勢させて調理容器３１に設けてもよく、これにより内鍋３４の温度を直接検知することができるので、より確実に内鍋３４の温度を検出することができる。
【００１８】
３７は調理容器３１の下部において、内壁３２と外壁３３との間に設けられた非磁性材からなるほぼ筒状のスカート部材で、炊飯器３０をトッププレート３上に載置したときに、その先端部がトッププレート３に当接するように形成し、調理容器３１の下端部から露出した内鍋３４の底面３４ｂがトッププレート３４に確実に当接すると共に、このすき間ｇを遮蔽して内鍋３４を外気から遮断するようにしたものである。
【００１９】
このスカート部材３７は、例えば図６（ａ）に示すように、シリコンゴムの如き軟質材からなり、上部が調理容器３１に固定されて常時はその先端部が内鍋３４の底面３４ｂより下方に位置している。炊飯器３０をトッププレート３上に載置すると、最初にスカート部材３７の先端部がトッププレート３に当接し、炊飯器３０の荷重により弾性変形するが、調理容器３１の下端部とトッププレート３との間にすき間ｇを形成した状態で調理容器３１を保持する。このとき、内鍋３４の底面３４ｂはトッププレート３に当接し、スカート部材３７は内鍋３４の外周を遮蔽する。
これにより、内鍋３４の底面３４ｂをトッププレート３に確実に当接させて効率よく発熱させることができると共に、外部からの空気や塵埃の侵入を防止し、また熱が外部に逃げるのを防止することができる。
【００２０】
また、図６（ｂ）のスカート部材３７は、非磁性金属からなり、調理容器３１の下部に上下動可能に設けたもので、常時は自重により垂下してその先端部が内鍋３４の底面３４ｂよりｇ_１だけ下方に位置している（図７（ｂ）参照）。炊飯器３０をトッププレート３上に載置すると、最初にスカート部材３７の先端部がトッププレート３に当接するが、炊飯器３０の荷重により上方に移動し、その自重により先端部が常にトッププレート３に当接する。このとき、内鍋３４の底面３４ｂはトッププレート３に当接し、その外周はスカート部材３７により遮蔽され、また、スカート部材３７の上部は補助加熱体である底側面加熱体３５の外周に位置する。なお、内鍋３４の底面３４ｂがトッププレート３に載置された状態で、スカート部材３７の先端部もトッププレート３に当接するが、このとき、スカート部材３７がストッパー３７ａに当接することにより、内鍋３４を調理容器３１より取り除いたときの調理容器３１の脚として使用できる。
図６（ｂ）のスカート部材３７は、図６（ａ）のスカート部材３７の機能、効果に加えて、誘導加熱コイルからなり底側面加熱体３５より発生する磁気を遮蔽し、外部への磁束漏れを防止することができる。
【００２１】
再び図３、図５において、３８は調理容器３１の上部開口部を開閉する蓋体で、とっ手４０を有する上蓋３９、上蓋３９に取付けられた下蓋４１、下蓋４１に着脱可能に装着された内蓋４２からなり、蓋体３８の中心部には内鍋３４内に連通する蒸気抜き弁４３が設けられている。４４は下蓋４１に設けた蓋ヒータである。そして、この蓋体３８は、一端に設けたヒンジ４５により調理容器３１に開閉自在に装着されており、閉じたときはラッチ４６によりロックされる。なお、この蓋体３８は、ヒンジ４５を設けることなく、調理容器３１に着脱自在に装着するようにしてもよい。
【００２２】
図７は炊飯器３０の他の例を示すもので、調理容器３１の外壁３３の背面側（加熱調理器１のガイド部１４側）に、ガイド部１４に嵌合する嵌合部４７を突設したものである。
この嵌合部４７は、その幅がガイド部１４のガイド壁１５ａ，１５ｂの内側間隔とほぼ等しく、先端部が下方に突出して係合部４８が設けられて側面ほぼ逆Ｌ字状に形成されている。このガイド部１４は、ガイド壁１５ａ，１５ｂが上方に突出して形成されるため使用者に見え易く、かつわかり易い位置に設けられているため、ガイド壁１５ａ，１５ｂの間に嵌合部４７を嵌入して係合部４８を開口部１６に係合させることにより、炊飯器３０はトッププレート３の載置部５ａ上に確実に位置するので、位置ずれ等により加熱効率が低下することがなく、また、炊飯器３０に外力が加えられても移動することもない。
【００２３】
次に、上記のように構成した加熱調理器の電気系統の一例について説明する。図８において、電源６５には、各加熱装置２０ａ〜２０ｃの誘導加熱コイル２２と、スイッチ素子２７ａ〜２７ｃからなる複数の直列回路が並列接続されて、メインスイッチ９を介して直列に接続されており、また、上記回路の入力側には、メニュースイッチ群１０、予約タイマー２６を有する制御部２５が接続され、予約タイマー２６はそれぞれスイッチ素子２７ａ〜２７ｃを制御する。
【００２４】
したがって、メインスイッチ９を投入してメニュースイッチ群１０の炊飯スイッチ１０ａをＯＮすれば、炊飯用の制御部２５ａ、スイッチ素子２７ａを介して加熱部２０ａの誘導加熱コイル２２に通電され、調理スイッチ１０ｂ又は１０ｃをＯＮすれば、調理用の制御部２５ｂ（２５ｃ）、スイッチ素子２７ｂ（２７ｃ）を介して加熱部２０ｂ（２０ｃ）の誘導加熱コイル２２に通電される。なお、必要に応じて予約タイマー２６を発動させれば、所定の時刻になったときはスイッチ素子２７ａ（又は２７ｂ，２７ｃ）をＯＮし、あるいは所定の時間経過したときは、スイッチ素子２７ａ（又は２７ｂ，２７ｃ）をＯＦＦする。
【００２５】
図９は電気系統の他の例を示すもので、本例においては、加熱調理器１のガイド部１４のガイド壁１５ａ，１５ｂの対向面の一方に、電源６５と加熱部２０ａの誘導加熱コイル２２の一端との間に接続された給電端子１７を設けると共に、他方の対向面に誘導加熱コイル２２の他端と電源６５との間に接続された給電端子１８を設け（図１３参照）、また、炊飯器３０の嵌合部４７の係合部４８の一方の側面に、補助加熱体３５，３６及び蓋ヒータ４４の一端に接続され、給電端子１７に接続される受電端子４９を設けると共に、他方の側面に、補助加熱体３５，３６及び蓋ヒータ４４の他端に接続され、給電端子１８に接続される受電端子５０を設けたものである（図１８参照）。
【００２６】
本例によれば、炊飯器３０をトッププレート３の載置部５ａ上に載置して嵌合部４７をガイド部１４に嵌入すると、係合部４８に設けた受電端子４９，５０が給電端子１７，１８に自動的に接続されて、補助加熱体３６，３７及び蓋ヒータ４４が電源６５に接続され、炊飯又は調理中、さらには保温中に補助加熱体３５，３６及び蓋ヒータ４４に通電される。なお、電源６５には商用電源をもちいてもよいが、高電圧の２００Ｖ電源を使用すれば、同時に複数の加熱部２０ａ〜２０ｃを使用する場合にも高出力が得られるので、調理時間を短縮することができる（以下の実施の形態においても同様である）。
【００２７】
次に、本実施の形態に係る加熱調理器の使用の一例について説明する。
前述のように、炊飯用の制御部２５ａには、保温モード回路である保温付き炊飯モード回路及び必要に応じて保温付き煮物モード回路が設けられている。保温付き炊飯モード回路による炊飯用制御パターンは、図１０に示すように、誘導加熱コイル２２に通電して米、水が入れられた炊飯器３０の内鍋３４を発熱させて加熱し、内鍋３４の温度が１００℃近傍に達したとき（これは温度センサ２３又は温度センサ２３ａで検出される）は、連続的又は断続的にその温度を維持し、時間Ｔを経過して炊飯が終了したときは、その温度を低下させてほぼ７３℃程度で保温する。
【００２８】
また、保温付き煮物モード回路は、図１１に示すように、誘導加熱コイル２２に通電して、煮物、水、調味料等が入れられた炊飯器３０の内鍋３４を発熱させて加熱し、内鍋３４の温度が１００℃近傍に達したときは、連続的又は断続的にその温度を維持し、時間ｔ（この時間ｔは、一般的にｔ＜Ｔである）経過したときは煮込み工程が終了し、以後例えば８０℃〜８５℃で保温（低温加熱）する。
【００２９】
炊飯器３０により米を炊飯する場合は、所要量の米と水が入れられた内鍋３４を調理容器３１内に収納して蓋体３８を閉じ、加熱調理器１のトッププレート３の炊飯器用の載置部５ａ上に載置する。このとき、調理容器３１はスカート部材３７によりその下端部がトッププレート３とすき間ｇを隔てて位置し、内鍋３４の底面３４ｂはトッププレート３に確実に当接する。また、調理容器３１に嵌合部４７を設けた場合は、炊飯器３０をトッププレート３上の所定の位置（載置部５ａ上）に載置するだけで、嵌合部４７がガイド部１４のガイド壁１５ａ，１５ｂの間に嵌入し、係合部４８が開口部１６に係合して容易かつ確実に位置決めされる。さらに、ガイド部１４に給電端子１７，１８を設け、炊飯器３０の嵌合部４７に受電端子４９，５０を設けた場合は、補助加熱体３５，３６及び蓋ヒータ４４が自動的に電源６５に接続される。
【００３０】
ついで主操作部８のメインスイッチ９を投入し、炊飯スイッチ１０ａをＯＮすれば、炊飯用の制御部２５ａを介して加熱部２０ａの誘導加熱コイル２２に通電される。このとき、予約タイマー２６が発動し、表示部１１に炊飯の残り時間が表示される。これにより、図１０の炊飯用制御パターンにしたがって炊飯され、保温される。なお、予約タイマー２６を使用せず、直接誘導加熱コイル２２に通電してもよい。
【００３１】
また、調理用の載置部５ｂ，５ｃの両方又はいずれか一方に、例えば煮物、水、調味料等が入れられた調理鍋６０ａ（６０ｂ）を載置し、調理スイッチ１０ｃ（１０ｃ）をＯＮすれば、炊飯と同時に１個又は２個の調理鍋６０ａ（６０ｂ）により調理を行うことができる。なお、煮物等の調理にあたっては、補助操作部１２により火力を調整することができ、その調整出力は表示部６ｂ（６ｃ）に表示される。また、予約タイマー２６を使用した場合は、その発動時刻又は残り時間が表示部１１に表示される。
【００３２】
上記の説明では、炊飯器３０により米を炊飯する場合について述べたが、同様にして炊飯器３０により米以外の煮物の調理を行うこともできる。
この場合は、調理容器３１に煮物、水、調味料等が入れられた内鍋３４を収容して炊飯器３０を炊飯器用の載置部５ａ上に載置し、煮物スイッチ１０ｂをＯＮすれば、図１１の煮物用制御パターンにしたがって調理され、保温（低温加熱）される。このとき、必要に応じて蓋体３８を開放し、煮物をかき混ぜたり、調味料等を入れたりすることができる。なお、内鍋３４を炊飯用と煮物用に分ければ、臭が残らないので便利である。
【００３３】
上記の説明では、トッププレート３の載置部５ａ上に載置した炊飯器３０により炊飯する場合を示したが、磁性材からなる通常の調理鍋でも炊飯を行うことができる。
すなわち、図１２に示すように、トッププレート３の載置部５ａ（又は５ｂ，５ｂ）上に米と水が入れられた調理鍋６０ｃを載置し、主操作部８のメインスイッチ９を投入して炊飯スイッチ１０ａをＯＮすれば、図１０の炊飯用制御パターンにしたがって炊飯され、保温される（以下の実施の形態においても同様である）。
【００３４】
上記のように構成した本実施の形態によれば、１台の加熱調理器１で炊飯器３０を含む複数の調理器により炊飯とその他の調理を同時に行うことができるため、料理のレパートリーが広がると共に、別に炊飯器を購入する必要がなく、また台所の省スペース化を図ることができる。
また、予約タイマー２６を設けたので、煮物等の他の調理の合間に炊飯用の準備をして炊飯器３０を載置部５ａ上に載置することができる。
さらに、炊飯器３０の内鍋３１の周囲に補助加熱体３５，３６を設けたので、炊飯器３０により炊飯や煮物等の一般の調理を行う場合に、内鍋３４がほぼ全体から加熱されるため加熱ムラがなく、効率よく調理することができ、また、保温性（低温加熱）を向上することができるので、いつでも暖かいご飯や料理を食べることができる。
【００３５】
［実施の形態２］
図１３は本発明の実施の形態２に係る加熱調理器の要部の斜視図、図１４はその電気系統図である。なお、以下の図面では実施の形態１と同じ部分にはこれと同じ符号を付し、説明を省略する。
本実施の形態においては、ガイド部１４の一方のガイド壁（例えば、１５ｂ）の内側（他方のガイド壁１５ａと対向する側）にスイッチ素子２７ａを介して電源６５に接続された給電端子１７を設けると共に、他方のガイド壁１５ａの内側に加熱器２０ａの誘導加熱コイル２２の一端に接続された給電端子１８が設けられている。また、開口部１６のトッププレート３側には載置スイッチ１９が設けられており、この載置スイッチ１９は、給電端子１７に接続された固定接点１９ａ、給電端子１８に接続された固定接点１９ｂ及び両固定接点１９ａ，１９ｂ間を開閉する可動片１９ｃとからなっており、可動片１９ｃは常時は両固定接点１９ａ，１９ｂ間を開放している。１６ａは開口部１６を開閉する開閉蓋で、不使用時には開口部１６を閉止してゴミや水の侵入を防止する。
【００３６】
このように構成した本実施の形態において、図７に示すような嵌合部４７をガイド壁１５ａ，１５ｂ間に嵌入し、係合部４８を開口部１６に係合させることにより炊飯器３０は載置部５ａ上に載置され、位置決めされる。同時に、載置スイッチ１９の可動片１９ｃが嵌合部４７に圧下されて両固定接点１９ａ，１９ｂ間を閉成し、電源６５と加熱部２０ａの誘導加熱コイル２２とが導通状態になる。
【００３７】
本実施の形態によれば、炊飯器３０をトッププレート３上に載置したときのみ制御部２５ａの保温付き炊飯モード回路が接続される。なお、一般の調理鍋等（６０ａ，６０ｂ）をトッププレート３上に載置したときに通常の調理が行えるようにしてもよい。
【００３８】
［実施の形態３］
図１５は本発明の実施の形態３に係る加熱調理器の電気系統図である。なお、以下の図面では実施の形態１と同じ部分にはこれと同じ符号を付し、説明を省略する。
本実施の形態において、加熱調理器１には、図１３で示したように、ガイド部１４の一方のガイド壁１５ａには電源に接続された給電端子１７が設けられ、他方のガイド壁１５ｂには給電端子１８が設けられている。また、開口部１６のトッププレート側には載置スイッチ１９が設けられており、この載置スイッチ１９は、給電端子１７に接続された共通端子１９ａ、スイッチ素子２７ａを介して炊飯用の加熱部２０ａの誘導加熱コイル２２に接続された固定接点１９ｂ、後述の炊飯器制御部５２が接続される固定接点１９ｃ、及び固定接点１９ｂ，１９ｃを切換える可動片１９ｄからなっている。なお、この可動片１９ｄは常時は一方の固定接点１９ｂに接続されている。
【００３９】
一方、炊飯器３０には、図１６〜図１９に示すように、嵌合部４７の係合部４８の一方の側面には、載置スイッチ１９の固定接点１９ｂに接続される受電端子４９が設けられており、他方の側面には、給電端子５２を介して載置スイッチ１９の固定接点１９ｃに接続される受電端子５０が設けられている。
【００４０】
また、炊飯器３０の蓋体３８の上蓋３９と下蓋４０との間には、保温モード回路である保温付き炊飯モード回路、必要に応じて保温付き煮物モード回路やタイマー回路が設けられた炊飯器（調理器）制御部５２が設けられており、この炊飯器制御部５２は、嵌合部４７の係合部４８に設けた受電端子４９，５０間に接続されている。そして、炊飯器制御回路５２はスイッチ素子５５を介して補助加熱体３５，３６及び蓋ヒータ４４の一端に接続され、補助加熱体３５，３６及び蓋ヒータ４４の他端は嵌合部４７の受電端子４９に接続されている。
さらに、上蓋３８の上面の炊飯器制御部５２上には、炊飯スイッチ５３ａ、煮物スイッチ５３ｂ、表示部５３ｃ等を有し、炊飯器制御部５２を制御する炊飯器（調理器）操作部５３が設けられている。なお、以下の説明では、炊飯器制御部５２と炊飯器操作部５３を合わせて、炊飯器制御装置５１という。また、上記の説明では、炊飯器制御装置５１を蓋体３８に設けた場合を示したが、調理容器３１に設けてもよい。
【００４１】
