Description

【０００１】
【発明の属する技術分野】
本発明は、冷却器用送風機を備えた食品冷却庫に関する。
【０００２】
【従来の技術】
一般に、圧縮機、凝縮器、減圧装置、及び庫内空気を冷却する冷却器を配管で接続した冷却回路を備え、冷却運転時には冷却器の風路内に配置された冷却器用送風機を運転させて、当該冷却器で熱交換した冷気を庫内に循環させ、庫内食品を冷却する食品冷却庫が知られている。
【０００３】
【発明が解決しようとする課題】
この種の従来の食品冷却庫では、食品を冷却する場合、当該食品に冷却風が強くあたると、食品が乾燥するという問題がある。この場合、例えばインバータ制御等により、冷却器用送風機の回転数の減速制御で対応しても、冷却器用送風機の吹出方向の正面に位置する食品には強く風があたるので、その部分の食品が乾燥し、食品毎に乾燥むらがでるという問題がある。
【０００４】
そこで、本発明の目的は、上述した従来技術が有する課題を解消し、食品の乾燥を抑制できる食品冷却庫を提供することにある。
【０００５】
【課題を解決するための手段】
請求項１記載の発明は、圧縮機、凝縮器、減圧装置、及び庫内空気を冷却する冷却器を配管で接続した冷却回路を備え、冷却運転時には冷却器の風路内に配置された冷却器用送風機を運転させて当該冷却器で熱交換した冷気を庫内に循環させ、庫内食品を冷却する食品冷却庫において、前記風路は両端開口をそれぞれ前記庫内に臨ませ、一方の開口に前記冷却器を配置し、他方の開口に前記冷却器用送風機を配置し、この冷却器用送風機は正逆回転可能に構成し、前記風路内の風路抵抗を、一方の開口から他方の開口への風の流れを強くしつつ、他方の開口から一方の開口への風の流れを弱くするように規定し、一方の開口から他方の開口に前記風路抵抗に応じた強い風を送風し、この他方の開口から庫内に強い冷却風を吹き出して庫内食品を急速冷却する急速冷却運転と、他方の開口から一方の開口に前記風路抵抗に応じた弱い風を送風し、この一方の開口から庫内全域に弱い冷却風を吹き出して庫内食品の乾燥を抑制する乾燥防止運転とを実行可能な構成としたものである。
【０００６】
請求項２記載の発明は、圧縮機、凝縮器、減圧装置、及び庫内空気を冷却する冷却器を配管で接続した冷却回路を備え、冷却運転時には冷却器の風路内に配置された冷却器用送風機を運転させて当該冷却器で熱交換した冷気を庫内に循環させ、庫内食品を冷却する食品冷却庫において、前記風路は両端開口をそれぞれ前記庫内の隣接する壁面に臨ませ、一方の開口に前記冷却器を配置し、他方の開口に前記冷却器用送風機を配置し、この冷却器用送風機は正逆回転可能に構成し、前記風路内の風路抵抗を、一方の開口から他方の開口への風の流れを強くしつつ、他方の開口から一方の開口への風の流れを弱くするように規定し、一方の開口から他方の開口に前記風路抵抗に応じた強い風を送風し、この他方の開口から庫内に強い冷却風を吹き出して庫内食品を急速冷却する急速冷却運転と、他方の開口から一方の開口に前記風路抵抗に応じた弱い風を送風し、この一方の開口から庫内全域に弱い冷却風を吹き出して庫内食品の乾燥を抑制する乾燥防止運転とを実行可能な構成としたものである。
【０００８】
これらの発明では、一方の開口から他方の開口に送風する場合と、他方の開口から一方の開口に送風する場合とで吹出口から庫内への冷気の吹出風速が異なるように構成したので、乾燥させてはいけない食品を冷却する場合には冷気の吹出風速が遅くなるように冷却器用送風機を回転駆動し、例えば急速冷却したい場合には冷気の吹出風速が速くなるように冷却器用送風機を回転駆動する。これにより、庫内食品を乾燥させずに冷却することができる。この場合に、吹出風速が遅くなる側の開口は、庫内壁面に大きく開口させ、この大きな開口から庫内全域に弱い冷却風を均一に吹き出す構成とすることが望ましい。
【０００９】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。
【００１０】
図１において、１はブラストチラー（以下、食品冷却庫という。）を示している。この食品冷却庫１の冷却庫本体１００にはヒンジを介して開閉扉１０１が連結され、この開閉扉１０１が開かれると、庫内９が臨んでいる。この庫内９には台車付きのストッカ１０２が格納自在であり、このストッカ１０２の棚にはトレー１０３が載置され、トレー１０３には冷却される食品が収容されている。また、冷却庫本体１００には液晶表示パネル１０５が設けられている。
【００１１】
この食品冷却庫１は、図２に示すように、２つの冷却ユニット３ａ、３ｂを備え、この２つの冷却ユニット３ａ、３ｂはそれぞれ冷媒配管５を介して冷却器７ａ、７ｂに接続されている。この冷却器７ａ、７ｂは風路に対し並列に一体形成され、庫内９につながる風路内に配置されている。
【００１２】
そして、この冷却器７ａ、７ｂには、この冷却器７ａ、７ｂで熱交換した冷気を庫内９に循環させるための、３台の冷却器用送風機１１ａ、１１ｂ、１１ｃが付設されている。これら３台の冷却器用送風機１１ａ、１１ｂ、１１ｃはそれぞれ調速手段（図示せず）を備えている。
【００１３】
一方の冷却ユニット３ａは定格圧縮機１３を備えている。この定格圧縮機１３の冷媒吐出管３ａには水冷式凝縮器１５が接続され、この水冷式凝縮器１５には水配管１６が付設されている。１７は水用電磁弁、１８は圧縮機用送風機、１９は圧縮機のオイルクーラを示している。水冷式凝縮器１５の冷媒出口管１５ａにはレシーバタンク２１、ドライコア２２が順に接続され、更に、冷媒配管５を介して膨張弁２３が接続されている。この膨張弁２３には前述した冷却器７ａが接続され、この冷却器７ａには冷媒配管５を介してアキュームレータ２４が接続され、このアキュームレータ２４は定格圧縮機１３の冷媒吸込管１３ｂに接続されている。また、定格圧縮機１３の冷媒吐出管１３ａにはバイパス管２５が接続され、このバイパス管２５はホットガス電磁弁２６を経て膨張弁２３の冷媒出口管２３ａに接続されている。
【００１４】
２つの冷却ユニット３ａ、３ｂの構成は同じであるので、他方の冷却ユニット３ｂの構成の説明は省略する。
【００１５】
この食品冷却庫１には、庫内温度を検出する庫内センサ３１と、食品の芯温を検出する芯温センサ（食品温度センサ）３３とが設けられ、冷却器７ａ、７ｂのそれぞれの出口管には、冷媒温度を検出する冷媒温度センサ３２ａ、３２ｂが取り付けられている。
【００１６】
この食品冷却庫１の庫内９には、スチームコンベクションオーブン（図示せず）等で加熱調理された、例えば７０℃程度の高温食品が投入される。この食品のいずれか一つには針状の芯温センサ３３を刺し、この芯温センサ３３によって食品の芯温が検出されている。
【００１７】
以上の構成によれば、冷却回路を複数備えることによって、庫内９に食品投入時は複数冷却ユニット３ａ、３ｂをすべて運転する制御が可能になり、庫内温度が設定温度に到達し、庫内温度を制御温度域（チルドモード）に維持する場合、一部の冷却ユニットを運転停止させ、残りの冷却ユニットをオン／オフ運転させる制御が可能になる。
【００１８】
この実施形態では、３台の冷却器用送風機１１ａ、１１ｂ、１１ｃがプロペラファンで構成され、各冷却器用送風機１１ａ、１１ｂ、１１ｃは正転或いは逆転のいずれの方向にも回転可能に構成されている。
【００１９】
図３は、冷却庫本体１００の横断面図である。
【００２０】
この実施形態では、冷却庫本体１００内に冷却風の風路５１が形成され、この風路５１は、Ｌ字状に曲がって両端開口５１ａ，５１ｂ（図１）をそれぞれ庫内９の隣接する壁面に臨ませている。
【００２１】
一方の開口５１ａは庫内壁面に大きく開口し、この開口５１ａの全面には冷却器７ａ、７ｂが配置され、他方の開口５１ｂには３台の冷却器用送風機１１ａ、１１ｂ、１１ｃが配置されている。冷却器用送風機１１ａ、１１ｂ、１１ｃが正転された場合、実線で示すように、一方の開口５１ａから他方の開口５１ｂに送風され、これが逆転された場合、点線で示すように、他方の開口５１ｂから一方の開口５１ａに送風される。
【００２２】
そして、風路５１内の風路抵抗は、実線で示す風の流れが強くなり、点線で示す風の流れが弱くなるように規定され、特に点線で示すように、他方の開口５１ｂから一方の開口５１ａに送風される場合、吹出風速が遅くなる側の開口５１ａでは、庫内壁面に開口する大きな開口５１ａから庫内９の全域に弱い冷却風がほぼ均一に吹き出される。
【００２３】
この実施形態では、冷却器用送風機１１ａ、１１ｂ、１１ｃが正転された場合、他方の開口（吹出口）５１ｂから強い冷却風が吹き出され、庫内食品が急速冷却される一方で、それが逆転された場合、一方の開口（吹出口）５１ａから庫内９の全域に弱い冷却風がほぼ均一に吹き出されるので、この弱い冷却風が食品にむらなくあたり当該食品の乾燥が抑制される。
【００２４】
これによれば、急速冷却したい場合、冷却器用送風機１１ａ、１１ｂ、１１ｃを正転させ、食品を乾燥させたくない場合、それを逆転させるだけでよいので、その制御を極めて簡単に実行することができる。
【００２５】
以上、一実施形態に基づいて本発明を説明したが、本発明はこれに限定されるものでないことは明らかである。
【００２６】
【発明の効果】
本発明では、一方の開口から他方の開口に送風する場合と、他方の開口から一方の開口に送風する場合とで、吹出口から庫内への冷気の吹出風速が異なるように構成したので、回転方向を変化させるだけの簡単な構成によって、冷気の吹出風速を増せば急速冷却が可能になると共に、冷気の吹出風速を減じれば冷却時の食品の乾燥を抑制することができる。
