Description

【0001】
【発明の属する技術分野】
本発明は、冷凍室に配置されるフリーザ容器を改良して熱損失を防ぐ貯蔵庫のフリーザ容器に関する。
【0002】
【従来の技術】
図4は、従来の貯蔵庫の冷凍室の概略の構成と冷気の流れを示す横断面図であって、1は断熱構造の本体であり、この本体1は、前方に開口する鋼板製の外箱2に間隔を有して組み込まれる前方に開口する硬質合成樹脂製の内箱3と、外箱2と内箱3との間に発泡断熱材4を充填して、内箱3に冷凍室5を形成している。
【0003】
冷凍室5の前面開口は、両側にパッキング7を設けた引き出し扉6により図示しないレールによって開閉自在に閉塞され、冷凍室5内に冷凍品を収納して冷凍するフリーザ容器8が取付けられている。
【0004】
フリーザ容器8は、図5に示すように、長方形状の上部が開口した箱状体で、背面壁の上端に冷気流路を形成する切欠け段部8aとこの切欠け段部8aに連なる両側の縁部8bと前面壁8dの上端8cに複数の冷気導出口8c1を形成して、図示しない手段によって引き出し扉6に取付けられている。また、冷凍室5は、後部に冷気導出部9を形成し、冷凍室5の後方には、冷却器10が配設されている。
【0005】
ここで、冷却器10で冷却された冷気が冷凍室5の冷気導出部9から図示矢印Aの如く流入し、冷気がフリーザ容器8の内側を通過して被冷凍品を冷却し、冷気はフリーザ容器8の前面壁8dの上端8cの複数の冷気導出口8c1から流出し、前面壁8dと引き出し扉6との間に形成される冷気流路を介して下方から冷却器10へ戻り循環される。
【0006】
【発明が解決しようとする課題】
ところで、従来の図4および図5に示したフリーザ容器8の構成では、フリーザ容器8の前面壁8dの上端8cの複数の冷気導出口8c1から流出した冷気の一部が図示B1,B2に示すように両側から左右の横方向へ流れて引き出し扉6と本体1とのパッキング7から外部へ冷気が漏れるおそれがあった。
【0007】
そこで、本発明は、かかる課題を解決するために、冷凍室の冷気の流れを規制して外部への冷熱の漏れを最小限に抑える貯蔵庫のフリーザ容器を提供することを目的とする。
【0008】
【課題を解決するための手段】
請求項1の発明は、前面を開口した本体と、該本体の開口を閉塞する扉と、本体と扉との内側に形成される冷凍室と、この冷凍室内に配置され上方に開口部を有する箱状体で形成し、この箱状体の背面壁の上端に冷気導入部を形成する一方、背面壁に対向する前面壁の上端に冷気導出口を形成したフリーザ容器とを備え、該フリーザ容器の冷気導入部から冷気を導入して冷気導出口から導出させ前面壁と扉との間に形成される冷気流路を介して冷気循環流路を形成する貯蔵庫のフリーザ容器において、フリーザ容器の前面壁の外側両端に、冷気流路の冷気を下方向へ案内し、かつ、左右方向へ流れる冷気を規制する冷気規制部材を設けるようにしたものである。この手段によれば、冷気規制部材によって冷気が下方へ流れて左右方向から扉のパッキングへ当たるのが防止される。従って、扉のパッキングでの熱の損失が軽減され、冷却能力が向上でき、消費電力量が軽減できる。
【0009】
請求項2の発明は、請求項1記載の貯蔵庫のフリーザ容器において、冷気規制部材は、冷気流路の左右方向への冷気の流れを仕切って扉のパッキングへ当たるのを防止する上下方向に立設される一対の規制リブを前面壁の外側両端に対応して取付けるようにしたものである。この手段によれば、規制リブによって冷気が扉のパッキングに当たるのを防止し、熱の損失が軽減される。
【0010】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して説明する。
【0011】
図1は、本発明の実施の形態を示す貯蔵庫である冷凍冷蔵庫の縦断面図であって、1は断熱造の本体(以下本体)であり、この本体1は前方に開口する鋼板製の外箱2内に間隔を有して組込まれる前方に開口する硬質合成樹脂製の内箱3と、外箱2と内箱3の間に現場発泡方式の発泡断熱材4を充填して構成されている。内箱3は上側の仕切壁11によって上下に区画され、この仕切壁11の上側に冷蔵室12が形成される一方、下側に2段の冷凍室5を形成し、さらに、下側の仕切壁13によって上下に区画され、上側に冷凍室5を形成し、下側に野菜室14が形成されている。
【0012】
冷凍室5の前面開口は、引き出し扉6にて図示しないレールによって開閉自在に閉塞され、この引き出し扉6には、それぞれ冷凍品を収納するフリーザ容器15が取付けられ、冷凍室5の背面には、冷却器10と冷気循環用装置である冷気用ファン16が冷却器室17に設けられている。
【0013】
冷蔵室12の前面開口は断熱を兼ねる扉18で開閉自在に閉塞され、冷蔵室12内には上下に3段の冷蔵品を載置する棚19が設けられ、冷蔵室12の下部には、棚20の下に氷温室21を配しており、扉18はビン類等を収納するポケット22を設けている。また、冷蔵室12の背面には、冷蔵室用冷却通路が形成されて冷気が冷蔵室12内へ吹き出すようになっている。なお、本体1の下部の野菜室14の後方の機械室23に圧縮機24が設けられている。
【0014】
冷凍室5の前面開口は、図2に示す横断面説明図のように両側にパッキング7を設けた引き出し扉6により図示しないレールによって開閉自在に閉塞される冷凍品を収納して冷凍する前述したフリーザ容器15が取付けられている。
【0015】
フリーザ容器15は、図3に示すように、長方形状の上部が開口した箱状体で、背面壁の上端に冷気流路を形成する切欠け段部15aと切欠け段部15aに連なる両側の縁部15bと複数の冷気導出口15c1を形成した前面壁15dの上端15cと前面壁15dの外側両端に、冷気を下方へ案内し、かつ、左右方向へ流れる冷気を規制し、冷気の熱損失を防止する冷気流路規制部材としての一対の規制リブ15eを対向させ上下方向に設けている。そして、フリーザ容器15は図示しない手段によって引き出し扉6に取付けられている。
【0016】
ここで、冷却器10で冷却された冷気が冷凍室5の冷気導出部9から図示矢印Aの如く、後方から流入し、冷気がフリーザ容器15内を通過して被冷凍品を冷却し、冷気はフリーザ容器15の前面壁15dの上端15cの複数の冷気導出口15c1から流出し前面壁15dと引き出し扉6との間を介して下方から冷却器10へ戻り循環される。
【0017】
この場合、図2および図3に示すように、冷気導出口15c1からの冷気が下方へ案内され、左右方向への冷気の流れが規制リブ15eによって規制され下方向へ冷気流路が形成される。これによって、前面壁15dと引き出し扉6との内側の空間から両側へ冷気が流れパッキング7で外部との熱交換が行われることが阻止される。従って、熱の損失が最小限に抑えられ、冷凍能力の向上が図られ消費電力が軽減できる。
【0018】
【発明の効果】
以上説明したように請求項1の発明によれば、冷気規制部材によって冷気が扉のパッキングに当たるのを防止するので、熱の損失を軽減して、冷却能力の向上を図ることができ、消費電力量を軽減することができる。
【0019】
また、請求項2の発明によれば、規制リブを設けたので、冷気が扉のパッキングに当たるのを防止でき、熱の損失を軽減することができる。
