Description

【０００１】
【発明の属する技術分野】
本発明は、冷気循環により食材表面を冷却しながら、マイクロ波などの高周波によって誘電加熱解凍する調理器の構造に関するものである。
【０００２】
【従来の技術】
冷凍物の解凍としては、自然放置解凍、冷蔵庫の冷蔵室放置解凍、流水解凍、電子レンジによる解凍、解凍室での伝導熱や輻射熱、温風利用による解凍などがある。
【０００３】
しかし、これらの解凍方法は、何れも非常に時間がかかったり、温度ムラ（解凍ムラ）が大きく高品位な解凍を望むことは困難であった。
【０００４】
これに対し、高周波を利用して解凍時間の短縮を実現した上、冷気を被解凍物の表面に吹き付けることで表面温度の上昇を防ぎ解凍ムラを防止するようにした解凍方法が考えられている。
【０００５】
従来のこの種の、調理器としては、冷気循環により食材表面を冷却しながら、マイクロ波などの高周波によって誘電加熱解凍するもの（例えば、特許文献１参照）がある。
【０００６】
以下、図面を参照しながら上記従来の調理器を説明する。図１２は、従来の調理器の断面図である。
【０００７】
図１２に示すように、従来の調理器１は、高周波の漏洩を防止する機構の付いた開閉自在の扉２、扉２により前面の開口部が開閉され周囲が金属でできた調理室３、調理室３の底面に設けられ被解凍物４を載せて回転させるための回転皿５、高周波を調理室３に送り込む導波管開口部６、調理室３に冷気を循環させるための冷気流入口７及び冷気流出口８が備えられ、調理室３の外側には表示部９、操作部１０、調理に必要な条件を入力する入力手段１１が備えられている。
【０００８】
冷気流入口７と冷気流出口８は高周波を遮断する電波遮蔽通風口で構成されており、この通風口で例えばパンチングメタルでできている。また、調理室３と冷気の循環通路１２は断熱材１３で被われており、冷気循環ファン１４を回して冷却手段としての冷却器１５で冷やされた空気を調理室３に送り込むようになっている。冷却器１５は圧縮機１７と接続されている。高周波加熱手段としての高周波発生装置１６は図示しない導波管で導波管開口部６に接続されている。
【０００９】
高周波発生装置１６は制御手段としての制御回路１８によって制御される。回転皿５上の被解凍物４は加熱開始とともに回転皿モータ２０によって回転される。また、冷気流入口７の冷気循環通路１２側には、冷気流入口７の一部を塞ぐ冷風調整手段１９が設けてあり、遮断板１９ａ，１９ｂを上下に動かすことによって、冷気流入口７から冷気が出てくる位置及び面積を変更することが可能になっている。
【００１０】
以上のように構成された調理器１について、以下その動作を説明する。
【００１１】
まず、事前に調理器１は圧縮機１７を運転して冷却器１５で空気を冷やし、冷気循環ファン１４を回転させて、調理室３を十分に、例えば０℃以下に冷却しておく。
【００１２】
次に、扉２を開け、被解凍物４を回転皿５に載せ、扉２を閉めて、この被解凍物４の解凍条件に必要な条件を入力手段１１に入力し、操作部１０を操作することによって解凍が開始される。このとき、表示部９には入力内容や動作状況が表示される。
【００１３】
解凍開始の操作に伴い、回転皿モータ２０に通電して被解凍物４を回転させ、高周波発生装置１６から調理室３に高周波を供給して、被解凍物４を加熱する。
【００１４】
このとき、圧縮機１６、冷気循環ファン１４を連続的に運転あるいは断続運転して冷気流入口７から調理室３内に例えば−１０℃の冷気を吹き込み、被解凍物４に冷気を当てながら高周波加熱で解凍する。

【発明が解決しようとする課題】
しかしながら、上記従来の構成は、調理器１が高周波の漏洩を防止する機構の付いた開閉自在の扉２と、調理室３と、断熱材１３で被われた冷気循環通路１２と、調理室３に冷気流入口７と冷気流出口８が備えられ、冷気循環ファン１４を回して、冷却手段としての冷却器１５で冷やされた空気を調理室３に送り込むようになっており、また、冷気流入口７の一部を塞ぐ冷風調整手段１９が設けられ、冷気が出てくる位置及び面積を変更する構成であるため、調理室３内は冷気循環通路１２により形状を複雑化し、構成部品及び、断熱材１３の材料注入時の発泡冶具など多くの部品と高額な冶具制作費でコストアップを招いたり、冷気循環通路１２も長くなると共に、冷気流入口７での冷風調整手段１９により風路抵抗を増し、冷気の風量を減らすことになるという欠点があった。
【００１７】
本発明は従来の課題を解決するもので、冷気循環通路により、調理室の形状を複雑にすることなく、また、冷気循環通路や冷気流入口部での冷風調整手段による風量減等を防止して、製造コストを下げ、安価で高品位な解凍を行うことができる調理器を提供することを目的とする。
【００１８】
また、上記従来の構成は、周囲が金属でできた調理室３は高周波を調理室３に送り込む導波管開口部６を備え、高周波加熱手段としての高周波発生装置１６は、導波管で導波管開口部６に接続された構成であるため、接続部よりの冷気洩れと共に冷却された調理室３から導波管を通じ高周波発生装置１６へ熱伝導し、結露を生じることになるという欠点があった。
【００１９】
本発明の他の目的は、導波管と高周波発生装置との接続部からの冷気洩れを防ぎ、導波管と高周波発生装置及び導波管内への結露を防止して、温度の安定化と錆や腐食の防止を図ることである。
【００２０】
また、上記従来の構成は、調理器１が高周波の漏洩を防止する機構の付いた開閉自在の扉２で調理室３の開口部を閉じた構成であるため、開閉自在の扉２による調理室３内の冷気洩れと、高周波の漏洩の防止の両立が出来ないという欠点があった。
【００２１】
本発明の他の目的は、開閉自在の扉部での調理室内の冷気洩れ、高周波の漏洩を防止して、温度の安定化と安全性の向上を図ることである。
【００２２】
【課題を解決するための手段】

【００２３】
請求項２に記載の調理器の発明は、請求項１に記載の発明に加えて、前記調理室の底面に回転可能に設けられた食材皿と、前記調理室の底面を貫通し前記食材皿と共に動く食材皿回転用シャフトと、前記食材皿回転用シャフトを介して前記食材皿に載せられた食材の重量を計量する重量検知手段と、前記重量検知手段からの検出信号に応じて前記冷気循環用ファンの回転を制御する制御手段とを有するものであり、冷却手段により冷却された冷却室内の空気は、冷気循環用ファンにより冷気流入口から調理室内に送り込まれ、また、調理室内の食材を載せる食材皿が回転するので、食材の表面へ冷気を効率よく当てることができ、食材の表面温度を一定に保つことができる。また、食材皿を回転させる食材皿回転用シャフトには、食材皿に載せられた食材の重量を計量する重量検知手段が設けられ、重量検知手段からの検出信号に応じて制御手段が冷気循環用ファンの回転を制御するので、食材を食材皿に載せるだけで計量でき、重量別の冷気循環用ファンの回転制御により冷気を効率良く食材に当てることができ、高品位解凍ができる。また、調理室底面と冷却室底面との空間には、調理室の底面を貫通する食材皿回転用シャフトと、食材皿回転用シャフトを介して食材皿に載せられた食材の重量を計量する重量検知手段とを、コンパクトに設けることができるので、調理室底面と冷却室底面との空間寸法を減らせて容積効率の向上ができる。また、冷却室の開口部から食材皿回転用シャフトと重量検知手段の取り付けが可能である。
【００２４】
請求項３に記載の調理器の発明は、請求項１または２に記載の発明において、前記調理室の外部側面に設けられた食材皿回転用モータが、前記調理室の底面を貫通し前記食材皿と共に動く前記食材皿回転用シャフトと、前記食材皿回転用シャフトと前記食材皿回転用モータとを連動させる連動手段とを介して、前記調理室の底面に回転可能に設けられる前記食材皿を回転させるものであり、冷却手段により冷却された冷却室内の空気は、冷気循環用ファンにより冷気流入口から調理室内に送り込まれ、また、調理室内の食材を載せる食材皿が回転するので、食材の表面へ冷気を効率よく当てることができ、食材の表面温度を一定に保つことができる。また、食材皿を回転させる食材皿回転用シャフトは、調理室の外部側面の離れた場所に設置した食材皿回転用モータと連動する連動手段で回転するので、調理室の底面を貫通する食材皿回転用シャフトに、調理室内に流された水等の液体が流入しても、食材皿回転用モータ部への流水を防止することができ、凍結防止による信頼性の向上を図ることができ、調理室底面と冷却室底面との空間寸法を減らせて容積効率の向上を図ることができる。また、冷却室の開口部から食材皿回転用モータの取り付けが可能である。
【００２５】
請求項４に記載の調理器の発明は、請求項１から３のいずれか一項記載の発明において、冷却された冷気を、風路断面積が前記冷気循環用ファンより大きい冷気流入ガイドの通路を通じて、前記冷気流入口全体から前記調理室に導くように構成したものであり、冷却された冷気を冷気循環用ファンの面積より大きい冷気流入ガイドの通路を通じて、冷気流入口全体から調理室に導くので、冷気流入口で最大の面積を確保でき、冷気流入口部での風路抵抗を補い冷却性能の低下を防止できる。
【００２６】

調理器２１下部の冷却機能部品収納箱２８には、圧縮機７８と、圧縮機７８の上に蒸発皿７９と、凝縮器８０と、膨張機構としてのキャピラリ―チューブと、凝縮器冷却ファン８１と、冷却制御盤８２が設置されている。
【００５１】
そして、圧縮機７８、凝縮器８０、高温冷媒循環用外周パイプ３４、キャピラリ―チューブ、蒸発器３１は順次環状に連接され、冷却室２２を冷却する冷却手段としての冷凍サイクル（蒸気圧縮式の冷凍システム）を形成する。
【００５２】
以上のように構成された本実施の形態の調理器について、以下その動作を説明する。
【００５３】
調理器制御表示盤７７部の電源の投入と同時に、圧縮機７８の起動により冷凍サイクルを動作させ、蒸発器３１により冷却を行う。このとき冷気循環用ファン４０により、調理室２５の空気を冷気流出口４３から冷気吸入口３０を通して蒸発器３１を通し冷気吐出口３２から冷気流入ガイド４１を通して冷気流入口４２から調理室２５内に循環させ−２０℃近くまで冷却を行う。
【００５４】
冷凍食品を解凍する場合、まず、冷凍食品を調理室２５内の食材皿４８に載置して扉２４と、調理室扉２６を閉止すると、調理室扉２６が扉開閉検知手段（扉フックスイッチ６３）を作動させ、冷気循環用ファン４０を回転させて、冷気を冷気流入口４２から調理室２５内に流入して、冷凍食品は冷気で覆われる。
【００５５】
そして、調理器制御表示盤７７部の調理食品選定スイッチで所定の調理食品を選定し、調理器制御表示盤７７部の調理スタートスイッチを操作することにより、高周波発生手段（高周波発生装置６９）は高周波を発振する。
【００５６】
高周波は導波管６７内を通って、励振口６８から調理室２５に入る。調理室２５に放出された高周波は、食材皿４８を回転させる食材皿回転用シャフト４７を介して重量検知手段（重量検知装置４６）により、重量を検知して調理器制御盤７６と高周波発生制御盤７４とにより高周波発生手段（高周波発生装置６９）からの高周波の出力を制御し、食材皿回転用モータ４９と食材皿回転用シャフト４７はベルト５１により、食材皿４８を回転させ食材への高周波の照射量調整と高周波分布を均一にする。
【００５７】
従って、冷凍食品は冷気に覆われ、表面からの解凍加熱の進行を抑制しつつ、冷凍食品の内部に徐々に解凍熱が浸透し、表面及び内部共にほぼ同一の加熱進行速度となって冷凍食品の解凍が行われる。そのため、加熱ムラのない良好な状態で冷凍食品の解凍を行うことができる。
【００５８】
本実施の形態の調理器では、蒸発器３１で冷却された冷気は、冷却室２２前面開口の外周部分を冷気シール用ガスケット３５付き扉２４により冷気洩れをなくした冷却室２２と、前面開口部外周を冷却室２２に取り付けた調理室２５との空間を通る。
【００５９】
その結果、冷却室２２内の調理室２５の周りに冷気を循環させているため、冷却室２２と調理室２５の空間が空気循環通路となり、冷却室２２と調理室２５を通路部品として共用することができるため、冷気循環通路用の部品をなくせる。
【００６０】
また、冷却部収納室２９内の蒸発器３１で冷却された冷気は、冷却室２２を通り、冷却室２２から冷却部収納室２９に還り、調理室２５は冷却される。このため、冷気循環通路の風路抵抗による冷気循環量の減少を押さえることができるため、調理室２５内の冷却低下を防ぐことが可能となる。
【００６１】
また、前面を開口した冷却室２２は奥部に冷却部収納室２９、続いて調理室２５と冷却室２２前面開口部から組み立てする配置としているため、冷却室２２の壁面のフラットを多くでき、また、断熱箱体を簡単な形状にでき、外箱２３の断熱材３６を注入発泡する時の冶具も簡素にすることができるため、組み立て易く、加工し易く、製造コストを低減することが可能となる。
【００６２】
また、柔軟材料で磁石を内蔵した冷気シール用ガスケット３５により扉２４を冷却室２２開口部の外周部分の位置に当接させることができるため、冷気循環通路からの冷気洩れをなくせる。
【００６３】
本実施の形態の調理器では、冷却用の冷媒は、圧縮機７８により圧縮され、高温となり凝縮器８０に送り出され、高温冷媒循環用外周パイプ３５、キャピラリ―チューブで減圧され、蒸発器３１を経て、圧縮機７８へと還る。
【００６４】
その結果、高温冷媒循環用外周パイプ３５を断熱材３３内へ設置した外箱２３面は、高温冷媒により加熱される。
【００６５】
このため、冷却室２２の冷気循環通路から伝わる熱伝導により、外箱２３面が冷やされる影響を押さえることができるため、外箱２３への結露を防ぐことが可能となる。
【００６６】
以上のように本実施の形態の調理器は、内部に前面を開口した冷却室２２が形成され外面を外箱２３で覆い冷却室２２と外箱２３との間に断熱材３３を設けた断熱箱体と、冷却室２２の開口部を開閉する扉２４と、冷却室２２を冷却する冷却手段としての冷凍サイクル（蒸気圧縮式の冷凍システム）の蒸発器３１と、冷却室２２内に設けられた前面を開口した金属で覆われた調理室２５と、調理室２５の開口部を開閉する金属製の調理室扉２６と、食材を加熱する高周波を発生させる高周波発生手段（高周波発生装置６９）と、外箱２３の上面を冷却室２２の側面との間を貫通して高周波発生手段（高周波発生装置６９）により発振した高周波を調理室２５内に導く導波管６７とを備えた調理器２１において、調理室２５は、下部を支える調理室２５の幅よりも長い支持部３８を冷却室２２の左右の壁に設けた溝３９に挿入され、さらに、前面開口部外周面を冷却室２２の間口開口を塞ぐ形で冷却室２２の空間内に設け、調理室２５内を冷却する調理室冷却手段としての調理室２５奥面外側の冷気循環用ファン４０と、調理室２５底面の外に固定され、バネと磁石または、圧電素子を備えた重量検知手段（重量検知装置４６）を設置した調理室２５の底面を貫通する食材皿回転用シャフト４７は、調理室の外部側面に回転可能に設けられた食材皿回転用モータ４９と、連動手段としての食材皿回転用シャフト４７部にプーリー５０と、食材皿回転用モータ４９間にベルト５１とで連動して回転させる食材皿４８と、調理室扉２６とを調理室２５と一体に設け、重量検知手段（重量検知装置４６）としてのバネと磁石または、圧電素子とからの検出信号に応じて調理室冷却手段としての調理室２５奥面外側の冷気循環用ファン４０の動作を制御する制御手段としての調理器制御盤７６とを設けたものである。
【００６７】
本実施の形態の調理器では、冷却室２５冷却手段としての冷凍サイクル（蒸気圧縮式冷凍システム）の蒸発器３１と、調理室２５冷却手段としての調理室２５奥面外側の冷気循環用ファン４０と、冷却部収納室２９の冷気吐出口３２が同じ高さ位置と、さらに、冷気循環用ファン４０より大きい冷気流入ガイド４１を前後方向に設け、冷気流入ガイド４１と同じ高さ位置の前後方向に備えた冷気流入口４２とで冷却冷気を直接調理室２５に送風し、調理室２５、冷却室２２に送り出された冷気は、冷却室２２前面開口部を覆う扉２４と、開口部冷気シール用ガスケット３５で洩れのないようシールし、調理室２５内に高周波を導く導波管６７の外箱２３上面貫通部は粘着性シール材７２で密封し、また、高周波発生手段（高周波発生装置６９）との間に気密シール材７０でシールし密閉したので、通路抵抗による冷気風量減を防止でき、冷却室２２冷却手段（蒸発器３１）による調理室２５内冷却時に調理室２５内への外気の流入による冷却低下を防ぐことができるため、調理室２５内への風量確保と、調理室２５内の温度の安定化により食材の表面温度を一定に保ち高品位解凍ができる。
【００６８】
また、食材を載せる食材皿４８と、重量検知手段としてのバネと磁石または、圧電素子を備えた食材皿回転用シャフト４７と、冷気循環用ファン４０の回転を制御する制御手段としての調理器制御盤７６を設けたので、食材の重量は載せるだけで計量できるため、重量別の冷気循環用ファン４０の回転制御により冷気を効率よく食材に当てることができ、高品位解凍ができる。
【００６９】
また、調理室２５の奥面に、冷気循環用ファン４０と、冷気流入ガイド４１と、底面に食材皿回転用シャフト４７と、バネと磁石または、圧電素子を備えた重量検知手段（重量検知装置４６）と、開口面に金属製の調理室扉２６とを設けたので、調理室２５と一体で取り付け、取り外しができるため、組み立て時あるいはサービス分解時の工数減により、製造あるいはサービスのコストを下げることができる。
【００７０】
なお、本実施の形態の調理器では、調理室２５の冷気流出口４３を調理室２５内の天井面、または左右面、さらに底面に設けても良く、その場合は、冷気流入口４２からの冷気を食材皿４８の食材全体に当てるようにできるので、解凍時の食材表面温度上昇を防ぐことが可能となる。
【００７１】
以上のように本実施の形態の調理器は、導波管６７と高周波発生手段（高周波発生装置６９）とを収納する解凍機能部品収納箱２７内露出部分の導波管６７が貫通する外箱２３天井部において、導波管６７と接続された高周波発生手段（高周波発生装置６９）との間に独立発泡タイプ等の気密シール材７０と、導波管６７と高周波発生手段（高周波発生装置６９）の接続部より外周の大きい露受け皿７３と、導波管６７が貫通する外箱２３天井部と露受け皿７３とを密封する粘着性シール材７２と、解凍機能部品収納箱２７には高周波発生手段（高周波発生装置６９）を制御する高周波発生制御盤７４と、高周波発生制御盤７４と高周波発生手段（高周波発生装置６９）を冷却する高周波発生装置冷却ファン７５とを設けたものである。
【００７２】
本実施の形態の調理器では、導波管６７と接続された高周波発生手段（高周波発生装置６９）との間に独立発泡タイプ等の気密シール材７０でシールしたので、接続部からの調理室２５内への冷気洩れを防ぎ、調理室２５内の温度の安定化により高品位解凍ができ、また、導波管６７内への結露を防ぐことにより錆や腐食を防止することができる。
【００７３】
また、導波管６７と高周波発生手段（高周波発生装置６９）の接続部より外周の大きい露受け皿７３としたので、冷却による導波管６７と高周波発生手段（高周波発生装置６９）への結露水を外箱２３天井部に排水することなく露受け皿７３に受けることができるため、高周波発生制御盤７４と高周波発生手段（高周波発生装置６９）を冷却する高周波発生装置冷却ファン７５の熱風により結露水を蒸発させ外箱２３天井部の錆や腐食を防止することができる。
【００７４】
また、導波管６７が貫通する外箱２３天井部と露受け皿７３とに粘着性シール材７０を塗布したので、導波管６７の貫通部からの冷気洩れと結露水の進入を防ぐことができるため、調理室２５内の温度の安定化により高品位解凍ができ、また、導波管６７が貫通する外箱２３天井部を粘着性シール材７０の密封により錆や腐食の防止をすることができる。
【００７５】

【００７６】
また、調理器２１の扉２４のスライド部３７と、調理室扉２６のフック部５５とは組み合わせ時隙間を持たせているので、調理器２１の扉２４及び調理室扉２６の取り付け位置ずれの吸収ができるため、調理室２５内の冷気洩れと、高周波の漏洩の防止の両立を図ることができる。
【００７７】
