【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６は、従来の調理器の断面図である。
【０００７】
図６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従来の調理器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、温皮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】

【００２７】
【発明の実施の形態】
以下、本発明による調理器の実施の形態について、図面を参照しながら説明する。
【００２８】
（実施の形態１）
図１は、本発明の実施の形態１による調理器の外観斜視図である。図２は、同実施の形態の調理器を左右に切断した場合の左側を右から見た縦断面図である。図３は、同実施の形態の調理器を前後に切断した場合の後ろ側を前から見た縦断面図である。図４は、同実施の形態の調理器おける扉の外周部を示す要部縦断面図である。
【００２９】
図１から図４に示すように、調理器２１は、内部に前面を開口する冷却室２２が形成され外面に外箱２３が設けられた断熱箱体と、冷却室２２内に前面を開口する調理室２４が底板２５と側板２６とで区画し形成され、冷却室２２と調理室２４の開口部を開閉するための扉２７が設けられている。断熱箱体（外箱２３）の上部に載置して設けられた解凍機能部品収納箱２８と、外箱２３と一体の下部に冷却機能部品収納箱２９の空間を有する。
【００３０】
冷却室２２奥面には、冷却部収納室３０が区画整理され冷却部収納室３０の冷気吸入口３１側には蒸発器３２、出口側には冷気循環用ファン３３と、冷気吐出口３４が設置されている。
【００３１】
また、調理器２１は、外箱２３における扉２７と対向する冷却室２２の開口部の外周部部分の外箱２３に内側面から熱交換可能に当接する高温冷媒循環用外周パイプ３５を断熱材３６内に埋設している。
【００３２】
さらに、外箱２３の冷却室２２と調理室２４開口部の前面を覆う断熱材３６入り扉２７を外箱２３に取り付けられたヒンジ３７を介して開閉するように設置されている。
【００３３】
扉２７には、冷却室２２開口部の外周部分に当接する位置に柔軟材料で磁石を内蔵した冷気シール用ガスケット３８と、冷気シール用ガスケット３８より内側の扉裏板３９に調理室２４の前面開口部の段付き部４０に金属製の電波遮蔽用高周波チョーク４１と、電波遮蔽用高周波チョーク４１の４隅に調節板４２と、扉裏板３９に電波遮蔽用高周波チョーク４１の４隅と同位置に保持板４３と、調節板４２と保持板４３とを固定し回動させる螺子等の連結部品４４と、電波遮蔽用高周波チョーク４１の外周にチョーク部を隠す高周波チョークカバー４５とを設けている。
【００３４】
さらに、調理室２４前面開口部外周面には、扉２７の開閉を関知する扉フックスイッチが設けられている。
【００３５】
調理室２４は、冷却室２２の前面開口部の段付き部４０より奥面に、冷却室２２の天井面と、側面と、奥面とを底板２５と側板２６とで区画し、冷却室２２のもう一方の側面と底面とで空間を保って設置されている。
【００３６】
また、調理室２４天井の断熱材３６内に冷気用通路４６と、調理室２４天井面の冷気用通路４６からの冷気を循環させる冷気流入口４７及び奥面に冷気流出口４８が備えられ、冷気流入口４７及び冷気流出口４８は高周波を遮断する電波遮蔽通風口で構成されており、この通風口は例えばパンチングメタルでできている。
【００３７】
さらに、調理室２４底板２５には、冷却室２２と区画した空間内に重量検知可能な食材皿回転用モータ４９が固定され、食材皿回転用モータシャフト５０は、調理室２４底板２５を貫通して調理室２４で食材皿５１が載置されている。
【００３８】
外箱２３の天井断熱材３６を貫通して冷却室２２内に挿入された導波管５２には、調理室２４の側板２６により区画された空間内の側板２６と固着され調理室２４内には励振口５３と、解凍機能部品収納箱２８部で導波管５２と接続された高周波発生装置５４と、導波管５２と高周波発生装置５４との間に独立発泡タイプ等の気密シール材５５と、断熱材３６内貫通部にはガラス繊維等の耐熱断熱材５６と、励振口５３にはマイカー板を取り付けている。
【００３９】
また、外箱２３と冷却室２２の天井貫通部は外箱２３側で粘着性シール材５７で密封されている。
【００４０】
また、導波管５２と、高周波発生装置５４が解凍機能部品収納箱２８内に露出した部分の外箱２３天井部に導波管５２と、高周波発生装置５４より外周の大きい露受け皿５８を備えている。
【００４１】
さらに、解凍機能部品収納箱２８には、高周波発生装置５４を制御する高周波発生制御盤５９と、高周波発生装置冷却ファン６０と、解凍機能部品収納箱２８前面に調理器２１を制御する調理器制御盤６１と、調理器制御表示盤６２が設置されている。
【００４２】
調理器２１下部の冷却機能部品収納箱２９には、圧縮機６３と、圧縮機６３の上に蒸発皿６４と、凝縮器６５と、膨張機構としてのキャピラリーチューブと、凝縮器冷却ファン６６と、冷却制御盤６７が設置されている。
【００４３】
そして、圧縮機６３、凝縮器６５、高温冷媒循環用外周パイプ３５、キャピラリーチューブ、蒸発器３２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。
【００４４】
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。
【００４５】
図示しない調理器制御表示盤６２部の電源の投入と同時に、圧縮機６３の起動により冷凍サイクルを動作させ、蒸発器３２により冷却を行う。このとき冷気循環用ファン３３により、調理室２４の空気を冷気流出口４８から冷気吸入口３１を通して蒸発器３２を通し冷気吐出口３４から冷気用通路４６を通して冷気流入口４７から調理室２４内に循環させ−２０℃近くまで冷却を行う。
【００４６】
冷凍食品を解凍する場合、まず、冷凍食品を調理室２４内の食材皿５１に載置して冷却室２２と調理室２４の扉２７を閉止すると、扉２７が扉フックスイッチを作動させ、冷気循環用ファン３３を回転させて、冷気を冷気流入口４７から調理室２４内に流入して、冷凍食品は冷気で覆われる。
【００４７】
そして、図示しない調理器制御表示盤６２部の調理食品選定スイッチで所定の調理食品を選定し、図示しない調理器制御表示盤６２部の調理スタートスイッチを操作することにより、高周波発生装置５４は高周波を発振する。
【００４８】
高周波は導波管５２内を通って、励振口５３から調理室２４に入る。調理室２４に放出された高周波は、食材皿５１を回転させる食材皿回転用モータ４９により、重量を検知して調理器制御盤６１と高周波発生制御盤５９とにより高周波発生装置５４からの高周波の出力を制御し、食材皿５１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。
【００４９】
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。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。
【００５０】
本実施の形態の調理器では、凝縮器３２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３８付き扉２７により冷気洩れをなくした冷却室２２の、冷却室２２内に底板２５と側板２６とで区画し形成された前面を開口する調理室２４内を通る。
【００５１】
その結果、冷却室２２内を区画した調理室２４内に冷気を循環させているため、冷却室２２内の調理室２４内が空気循環通路となり、冷却室２２内と調理室２４内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。
【００５２】
また、冷却部収納室３０内の蒸発器３２で冷却された冷気は、冷却室２２を区画した調理室２４を通り、冷却部収納室３０に還り、調理室２４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２４内の冷却低下を防ぐことが可能となる。
【００５３】
また、前面を開口した冷却室２２は奥部に冷却部収納室３０、続いて冷却室２２を区画した調理室２４を冷却室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の壁面をフラットにでき、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単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。
【００５４】
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３８により、扉２７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洩れをなくせる。
【００５５】
本実施の形態の調理器では、冷却用の冷媒は、圧縮機６３により圧縮され、高温となり凝縮器６５に送り出され、高温冷媒循環用外周パイプ３５、キャピラリーチューブで減圧され、蒸発器３２を経て、圧縮機６３へと還る。
【００５６】
その結果、高温冷媒循環用外周パイプ３５を断熱材３６内へ設置した外箱２３面は、高温冷媒により加熱される。
【００５７】
このため、冷却室２２と調理室２４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。
【００５８】
以上のように本実施の形態の調理器は、内部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３６を設けた断熱箱体と、冷却室２２内に設けられた前面を開口した調理室２４と、冷却室２２と調理室２４の開口部を開閉する扉２７と、冷却室２２と調理室２４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３２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）５４と、外箱２３の上面を冷却室２２内に貫通し高周波発生手段（高周波発生装置）５４により発振した高周波を調理室２４内に導く導波管５２とを備えた調理器２１において、調理室２４は冷却室２２内を底板２５と、側板２６とで区画し設けたと、底板２５を貫通する食材皿回転用モータシャフト５０を回転させ同時に重量検知手段としてのバネと磁石とを備えた食材皿回転用モータ４９と、底板２５に回転可能に設けられた食材皿回転用モータシャフト５０に連結される食材皿５１と、側板２６に導波管５２の励振口５３を設けたと、重量検知手段としてのバネと磁石とからの検出信号に応じて調理室２４冷却手段としての冷却部収納室３０内の冷気循環用ファン３３の作動を制御する制御手段としての調理器制御盤６１とを設けたものである。
【００５９】
本実施の形態の調理器では、冷却室２２と調理室２４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３２と冷却室２２奥面の区画整理された冷却部収納室３０内の冷気循環用ファン３３と、冷気用通路４６とで冷却冷気を直接冷却室２２と調理室２４に送風し、冷却室２２と調理室２４に送り出された冷気は冷却室２２前面開口部を覆う扉２７と、開口部冷気シール用ガスケット３８で洩れのないようシールし、調理室２４内に高周波を導く導波管５２の外箱２３上面貫通部は粘着性シール材５７で密封し、また、高周波発生手段（高周波発生装置）５４との間に気密シール材５５でシールし密閉としたので、通路抵抗による冷気風量減を防止でき、冷却室２２と調理室２４冷却手段（蒸発器３２）による冷却室２２と調理室２４内冷却時に調理室２４内への風量確保と、調理室２４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。
【００６０】
また、食材を載せる食材皿５１と、重量検知手段としてのバネと磁石を備えた食材皿回転用モータ４９と、冷気循環用ファン３３の回転を制御する制御手段としての調理器制御盤６１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３３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。
【００６１】
また、調理室２４を区画した底板２５に食材皿回転用モータ４９を設けたので、調理室２４は区画する底板２５と側板２６の取り付け、取り外しでできるため、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。
【００６２】
なお、本実施の形態の調理器では、調理室２４の冷気流出口４８を調理室２４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４７からの冷気を食材皿５１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。
【００６３】
以上のように本実施の形態の調理器は、導波管５２と高周波発生手段（高周波発生装置）５４とを収納する解凍機能部品収納箱２８内露出部分の導波管５２が貫通する外箱２３天井部において、導波管５２と接続された高周波発生手段（高周波発生装置）５４との間に独立発泡タイプ等の気密シール材５５と、導波管５２と高周波発生手段（高周波発生装置）５４の接続部より外周の大きい露受け皿５８と、導波管５２が貫通する外箱２３天井部と露受け皿５８とを密封する粘着性シール材５７と、解凍機能部品収納箱２８には高周波発生手段（高周波発生装置）５４を制御する高周波発生制御盤５９と、高周波発生制御盤５９と高周波発生手段（高周波発生装置）５４を冷却する高周波発生装置冷却ファン６０とを設けたものである。
【００６４】
本実施の形態の調理器では、導波管５２と接続された高周波発生手段（高周波発生装置）５４との間に独立発泡タイプ等の気密シール材５５でシールしたので、接続部からの調理室２４内への冷気洩れを防ぎ、調理室２４内の温度の安定化により高品位解凍ができ、また、導波管５２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。
【００６５】
また、導波管５２と高周波発生手段（高周波発生装置）５４の接続部より外周の大きい露受け皿５８としたので、冷却による導波管５２と高周波発生手段（高周波発生装置）５４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５８に受けることができるため、高周波発生制御盤５９と高周波発生手段（高周波発生装置）５４を冷却する高周波発生装置冷却ファン６０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。
【００６６】
また、導波管５２が貫通する外箱２３天井部と露受け皿５８とに粘着性シール材５７を塗布したので、導波管５２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２４内の温度の安定化により高品位解凍ができ、また、導波管５２が貫通する外箱２３天井部を粘着性シール材５７の密封により錆や腐食の防止をすることができる。
【００６７】
