【発明の属する技術分野】
本発明は引き出し式の扉及び容器を備えた冷蔵庫の関する。
【０００２】
【従来の技術】
近年、冷凍室、独立した低温室、野菜室など引き出し式の扉及び容器を備えた冷蔵庫が主流となっている。例えば特開平３−１１０３７６号公報にその一例が示されており、以下、図１１、図１２を参照しながら説明を行う。
【０００３】
１は外箱２、内箱３及び前記両箱２、３間の空間に充填された断熱材４によって構成された冷蔵庫本体で、５は引き出し式の扉６を備えた独立した貯蔵室である。
【０００４】
７は前記内箱３の両側面に奥方向に沿って左右の対向位置に形成された凹陥溝、８は前記凹陥溝７に嵌着した断面コの字状の固定レール、９は前記固定レール８の前端部近傍の左右の両内箱側壁に回転自在に枢着した固定ローラーである。
【０００５】
１０は扉６の固着され、前記固定ローラー９上に摺動自在に支持されているフレームであり庫内奥行き方向に延びている。１１は前記フレーム１０の後端部に回転自在に枢着された移動ローラーであり固定レール８内を転勤するよう構成されている。１２は食品を収納するための容器であり、上部開口部周囲のフランジ１３によりフレーム１０に載置され扉６の開閉動作に合わせて一体に引き出し、収容されるよう構成されている。
【０００６】
以上のように構成された冷蔵庫についてその動作を説明する。扉６を引き出すことにより、フレーム１０が固定ローラー９上を移動し、またフレーム１０後端部の移動ローラー１１が固定レール８のコの字状の内面を移動して、フレーム１０上に載置された容器１２が引き出される。
【０００７】
【発明が解決しようとする課題】
しかしながら上記の構成では、本体内箱両側面より庫内側に向けて固定レール、フレーム、容器のフランジが順次係合する構造であるためこの部の構成に庫内寸法を費やし、実際の容器の内寸幅が大きく取れず貯蔵室の間口容積に対して実効内容積が相当小さくなるという問題点があった。
【０００８】
本発明は、貯蔵室の間口容積に対して実効容積比率の高い引き出し容器の構成を提供することを目的とする。
【０００９】
【課題を解決するための手段】
上記課題を解決するために本発明の冷蔵庫は、両側面に空気層を形成した二重構造の引き出し容器の両側面部を相対する内箱両側面の凹陥溝に嵌合せしめて引き出すよう構成したものである。これにより、貯蔵室の間口の幅寸法に近似した引き出し容器が得られる。
【００１０】
また、容器の空気層内に断熱材を封入したものである。これにより、容器の空気層厚みを縮小でき、さらに内寸幅の広い引き出し容器が得られる。
【００１１】
また、容器の空気層内に冷気の通風ダクトを構成したものである。これにより、加えて冷気が容器内に直接通風されず収納物が間接冷却される。
【００１２】
また、容器の空気層内に冷気の通風ダクトを構成するとともに容器内底面を金属板、蓄冷板等の冷却補助板で構成したものである。これにより、加えて容器底面からの冷却が促進される。
【００１３】
また、扉と引き出し容器を一体二重構造として断熱材を封入したものである。これにより、扉と引き出し容器の連結部の無効容積が減少し、さらに実効容積の大きい引き出し容器が得られる。
【００１４】
また、容器外側底面に引き出し用レールを構成したものである。これにより、操作性を損なわずに内寸幅の広い引き出し容器が得られる。
【００１５】
【発明の実施の形態】
本発明の請求項１に記載の発明は、本体内箱の両側面に形成した凹陥溝と、前記凹陥溝に嵌合する少なくとも両側面に所定厚みの空気層を形成した二重構造の容器と、前記容器を支持する引き出し扉を設けたものであり、容器の両側面空気層が空気断熱の役目を果たし、凹陥溝部の断熱厚みと空気断熱厚みの合計厚みが本体両側面厚みに近似した構成となる。
【００１６】
請求項２に記載の発明は、容器の空気層内に断熱材を封入したものであり、容器の両側面が断熱構成となり、凹陥溝部の断熱厚みと容器断熱厚みの合計厚みが本体両側面厚みと同等になる。
【００１７】
請求項３に記載の発明は、容器の空気層内を冷気の通風ダクトとしたものであり、容器内の食品が間接冷却されて貯蔵室内湿度が高まる。
【００１８】
請求項４に記載の発明は、容器の空気層内を冷気の通風ダクトとしたものにおいて容器の内側底面を金属板、蓄冷板などの冷却補助板で構成したものであり、容器内の食品が間接冷却されて貯蔵室内湿度が高まる一方で、冷却補助板での冷却が促進される。
【００１９】
請求項５に記載の発明は、本体内箱の両側面に形成した凹陥溝と、二重構造で内部に空気層を設けて一体に形成された容器および引き出し扉と、少なくとも容器両側面と扉の空気層内に断熱材を封入し、前記凹陥溝に容器両側面を嵌合したものであり、扉と引き出し容器の連結部構造やスペースが不要となる。
【００２０】
請求項６に記載の発明は、容器の外側底面に引き出し用レールを係合するものであり、本体両側面にレール構成が不要となり容器両側面と本体が近接する。
【００２１】
以下本発明の実施の形態について、図１から図１０を用いて説明する。
（実施の形態１）
図１から図４において、１４は引き出し式扉１５を備えた貯蔵室であり、室内両側壁には相対応する位置に奥行き方向に凹陥溝１６が延出している。１７は前記引き出し式扉１５に支持された食品を収納する容器であり、例えばブロー成型などの樹脂製の二重構造で両側面に所定厚みの空気層１８が形成されている。また、容器１７の両側面は本体両側壁に形成された前記凹陥溝１６に嵌合し、本体凹陥溝１６部の断熱厚みと容器１７の空気層１８の厚みを合わせて本体の基準厚みに近似した厚みに構成されている。１９は前記容器１７の外底面と貯蔵室１４の底面との間で係合するように奥行き方向に設けられた引き出し用レールであり、フレーム１９ａ、レール１９ｂ、ベアリング１９ｃより構成されている。
【００２２】
かかる構成において、容器両側面の空気層１８は空気断熱の作用を行い、対応する本体凹陥溝１６部の断熱厚みの局部的な薄さを補償することになる。合わせて、底部に設けた引き出し用レール１９によって容器両側面部の無効空間が削減でき、このため容器１７の内側壁間の幅は貯蔵室１４の間口幅に近似した寸法にまで拡大され、容器１７の実効容積が大きくなって食品の収納量が増加する。
【００２３】
（実施の形態２）
図５において、２０は二重構造の容器１７の両側面の空気層１８内に封入された断熱材である。
【００２４】
かかる構成において、容器両側面の空気層１８は断熱材２０の封入によってさらに断熱効果が高められ、容器１７の両側壁に厚みがより薄くても対応する本体凹陥溝１６部の断熱厚みの局部的な薄さを補償する。このため容器１７の内側壁間の幅は貯蔵室１４の間口幅と同等の寸法にまで一層拡大され、容器１７の実効容積がさらに大きくなって食品の収納量がさらに増加する。
【００２５】
（実施の形態３）
図６、図７において、２１は例えば、ブロー成型などの樹脂製の二重構造で、所定厚みに形成された空気層に冷却用冷気の通風ダクト２２が構成されている。２３は容器２１の背面に設けられ前記通風ダクト２２内に冷気を導入させるための冷気導入口であり、２４は容器底面に設けられて通風ダクト２２内を循環した冷気を排出する冷気排出口である。
【００２６】
かかる構成において、冷気導入口２３より導入された冷気は二重構造の空気層に形成された通風ダクト２２内を通過して冷気排出口２４より排出される間に容器２１の内面を間接冷却する。このため従来のように貯蔵室１４内に冷気の通風循環スペースを別途確保する必要がなく容器２１の実効容積が一層大きくなって食品の収納量がさらに増加する。また、容器２１内に直接冷気を通風しないため食品自身の水分によって適度に湿度が保たれ、収納食品の乾燥が抑制される。
【００２７】
（実施の形態４）
図８、図９において、２５は例えばブロー成型などの樹脂製の二重構造で、内面側の底面が開口されている。２６は例えばアルミなどの熱伝導性の良い金属板や蓄冷板などの冷却補助板であり、容器底面の開口部に載置されている。２７は前記容器２５の周囲に二重構造の空気層を利用して所定厚みに形成された冷却用冷気の通風ダクトである。２８は容器２５の背面に設けられ前記通風ダクト２７内に冷気を導入させるための冷気導入口であり、２９は容器底面に設けられて通風ダクト２７内を循環した冷気を排出する冷気排出口である。
【００２８】
かかる構成において、冷気導入口２８より導入された冷気は二重構造の空気層に形成された通風ダクト２７内を通過して冷気排出口２９より排出される間に容器２５の内面を間接冷却する。この時、容器底面を通過する冷気は通風ダクト２７と熱交換的に設けられた冷却補助板２６を冷却し容器内に収納された食品の冷却が促進される。このため従来のように貯蔵室１４内に冷気の通風循環スペースを別途確保する必要がなく容器２１の実効容積が一層大きくなって食品の収納量がさらに増加する。また、容器２１内に直接冷気を通風しなくても冷却補助板２６によって十分な冷却能力が確保されながら食品自身の水分によって適度に湿度が保たれ、収納食品の乾燥が抑制される。
【００２９】
（実施の形態５）
図１０において、３０は例えばブロー成型などの樹脂製の二重構造で、両側面に所定厚みの空気層１８が形成された容器であり、３１は前記容器と一体に二重成型された引き出し式の扉である。また、３２は前記容器３０および扉３１の空気層内に封入された断熱材である。
【００３０】
かかる構成において、容器３０と扉３１が一体に成形されるため両者の連結部に連結構造やスペースが必要なくなり一層貯蔵室１４内の無効スペースが減少し、容器の実効容積がより大きくなって食品の収納量がより増加する。また、容器と扉の一体化によって製造コストや製造工数が削減できる効果も併せ持つことができる。
【００３１】
【発明の効果】
以上のように本発明の冷蔵庫によると、引き出し式の扉を備えた貯蔵室の容器内実効容積を大きく増加させることができ、特に容器の幅方向の内寸を貯蔵室の間口とほぼ同等に拡大できることによって、容器を引き出した際の収納性が高まるほかワイド感が得られ視覚的な商品価値が高まる。
【００３２】
また、二重構造の容器に冷却ダクト機能を付加することによって無効スペースのさらなる削減による容器の実効容積増加や食品の間接冷却による乾燥防止効果が得られる。さらに、容器と扉を二重構造の一体構造とすることで一層無効スペースが削減でき容器の実効容積増加が図れると同時に製造コストや製造工数が削減できる効果も併せ持つことができる。
