Description

【0001】
【発明の属する技術分野】
本発明は、冷蔵庫に関する。
【0002】
【従来の技術】
従来の冷蔵庫は、例えば圧縮機の運転を停止した際に、冷凍室用のダンパーユニットを開いて、送風機を運転することにより、蒸発器に附着した霜を昇華させながら冷蔵室へと送風して冷蔵室の湿度を高くし、野菜その他の食品が水分を保持して鮮度を維持するようにしたものがある。
【0003】
この従来の冷蔵庫は、冷凍室用のダンパーユニットが、送風機の前方(冷凍室の奥行方向)に配置されて、冷凍室内の全体に冷却空気が吹き出されるようになっている。このような冷蔵庫は、例えば特開2001−241825号公報に記載されている。
【0004】
【発明が解決しようとする課題】
しかしながら、前述した従来の冷蔵庫は、冷凍室用のダンパーユニットが、送風機の前方に配置されていることから、奥行き方向の寸法が大きくなり、冷凍室の庫内収納容積が小さくなってしまう。また、従来の冷蔵庫は、空気抵抗が増大することにより冷凍室への吐出風量が減少する可能性を有している。更に、従来の冷蔵庫は、冷凍室の空気循環制御を行うダンパーユニットが、送風機の前方にあるので、蒸発器にて冷却され冷却前よりも重くなった冷気を、一旦ダンパーユニットのダンパーよりも上方に位置するダンパーユニットの吸込口まで持ち上げるように送風する必要があり、送風機がその分だけ余計にエネルギーを必要とし、消費電力が大きくなる問題がある。
【0005】
以上のことから本発明の第1の目的は、冷凍室の収納容積が小さくなるのを抑制し、更に、送風機の圧損を少なくし、消費電力量を低減した冷蔵庫を提供することにある。
【0006】
また、上記従来の冷蔵庫は、冷凍室内全体に冷却空気が吹き出される構成のため、冷凍室の庫内容積を大きくした場合に、製氷時間を短縮すること、食品を短時間に冷凍することが困難である。本発明の第2の目的は、製氷又は食品をホームフリージングする際に、アイスメーカーや急速冷凍する部分へ冷たい冷却空気を集中的に吐出させることで短時間に製氷や食品のホームフリージングができる冷蔵庫を提供することにある。
【0007】
更に、冷凍室の庫内容積を大きくした場合に、冷凍室内の温度分布を均一化するためには、冷気を冷凍室内に吐出する冷気吐出口を多く設けることにより解決する手法があるが、多くの冷気吐出口を設けると、冷凍室内部の有効内容積を狭めることになってしまう。
【0008】
また、送風機からの距離が遠い冷気吐出口から吐出された冷気(複数ある冷気吐出口の中で下流にある冷気吐出口)は、通路抵抗により風量が減少すると共に、吐出流速が遅くなるため、複数の冷気吐出口を設けたとしても、冷凍室内の温度分布を十分に均一化できない可能性がある。
【0009】
本発明の第3の目的は、複数の冷気吐出口を設けた場合、冷凍室庫内の有効内容積の減少を抑制し、下流の冷気吐出口からの吐出流速を上流の冷気吐出口からの吐出流速と大きく違わないようにして、冷凍室内の温度分布の均一化を図った冷蔵庫を提供することにある。
【0010】
更にまた、ダンパーユニットを設けるとダンパーユニットの体積又はダンパーを駆動する駆動部の体積が冷蔵庫内をデットスペースとし、有効内容積を少なくする問題があった。本発明の第4の目的は、ダンパーユニット又はダンパーを駆動する駆動部が有効内容積を縮めないところに配置され有効内容積を大きくできる冷蔵庫を提供することにある。
【0011】
即ち、本発明は、庫内の有効内容積を広くし、消費電力を低減させ、使い勝手の良い冷蔵庫を提供することを目的としている。
【0012】
【課題を解決するための手段】
上記第1の目的は、冷蔵室と、この冷蔵室よりも下方に位置する冷凍室と、一つの蒸発器と、この蒸発器と熱交換した冷却空気を送風する一つの送風機と、送風された冷却空気の冷凍室への送風を制御する冷凍室用ダンパーユニットと、送風された冷却空気の冷蔵室への送風を制御する冷蔵室用ダンパーユニットとを備え、前記冷凍室用ダンパーユニットの冷却空気の吸込口が前記送風機と重ならず、送風機の回転中心軸よりも下に位置させることにより達成される。
【0013】
即ち、上記構成を有した冷蔵庫は、冷凍室の収納容積が小さくなるのを抑制すると共に、重い冷気を送風機が上方に持ち上げるように送風する必要を無くして送風機の圧損を少なくし、消費電力量を低減している。
【0014】
上記第2の目的は、冷凍室が、この冷凍室を正面から見て左右に区画する仕切壁と、この仕切壁により仕切られた冷凍室の左右どちらか一方の最上部に配置された製氷室又は急速冷凍室とを備え、冷凍室用ダンパーユニットが前記製氷室又は急速冷凍室への送風を制御するダンパーユニットであることで達成される。
【0015】
このような構成を有した冷蔵庫は、蒸発器で冷却された冷たい空気を製氷室又は急速冷凍室に集中的に吹き付け、短時間に製氷又は食品のホームフリージングを行うことができる。
【0016】
また、第2の目的は、冷凍室が、この冷凍室を正面から見て左右に区画する仕切壁と、この仕切壁により仕切られた冷凍室の左右どちらか一方の最上部に配置される製氷室と、他方の冷凍室の最上部に配置される急速冷凍室とを備え、前記製氷室への送風を制御するダンパーユニットと、前記急速冷凍室への送風を制御するダンパーユニットとを、左右に並べて配置することでも達成することができる。このような構成の冷蔵庫では、ダンパーユニットを左右方向に並べて配置したことで、冷凍室の最上部に配置された製氷室及び急速冷凍室のいずれにも送風機からの距離が短くなり、送風機からの冷却空気を短い距離で集中的に供給できることにより、より短時間に冷凍することができる。
【0017】
また、第2の目的は、冷蔵室と、冷凍室と、庫内空気を冷却する蒸発器と、この蒸発器と熱交換した冷却空気を送風する送風機と、前記冷蔵室へと送風される冷却空気の送風量を制御する冷蔵室用ダンパーユニットと、前記冷凍室へと送風される冷却空気の送風量を制御する冷凍室用ダンパーユニットとを備え、前期冷凍室が、製氷室又は急速冷凍室と、前記冷凍室用ダンパーユニットにより送風量が調整された冷却空気を導入する冷気導入部を有し、前記冷凍室用ダンパーユニットのダンパーが、その先端を前記冷気導入部に対向する角度で停止させることで達成することができる。
【0018】
即ち、このような冷蔵庫では、製氷又は食品をホームフリージングする際に、ダンパーの先端が冷却空気の冷気導入部の先端に対向させて、ダンパーユニットの吸込口を経由した多くの冷却空気を集中的に吹き付け、短時間で製氷又は冷凍することができる。
【0019】
更に、第2の目的は、冷凍室用ダンパーユニットが、その冷却空気の吸込口を送風機の回転中心軸よりも下に位置させることで、蒸発器で冷却された重たい冷却空気を送風機で持ち上げることなくスムーズに送風できる。
【0020】
上記第3の目的は、冷凍室が、複数の収納容器と、この収納容器又は収納容器内部にダンパーユニットからの冷却空気を導入する冷気導入部と、前記ダンパーユニットと前記冷気導入部との間を繋ぎ、通路内の断面積が下流に行くほど小さくなる冷気吐出通路とを備えることで達成される。
【0021】
即ち、このような構成の冷蔵庫は、冷気吐出通路内が下流に行くほど狭いことで冷気吐出通路内の流速が低下するのを防ぎ、かつ、各段の貯蔵食品を入れる容器又は棚上に流速の速い風を流入させるために、容器毎又は収納空間毎に冷却空気を導入するための冷気導入部を設け、冷気導入部を境に風量が減じる分冷気吐出通路を狭めるようにする。これにより冷却空気の流速の低下を抑制できる。そして、冷気吐出通路を狭めた分、冷凍室内の奥行きを広くして有効内容積を大きくすることもできる。
【0022】
第4の目的は、冷蔵室と、冷凍室と、庫内空気を冷却する蒸発器と、この蒸発器と熱交換した冷却空気を送風する送風機と、前記冷蔵室へと送風される冷却空気の送風量を制御する冷蔵室用ダンパーユニットと、前記冷凍室へと送風される冷却空気の送風量を制御する冷凍室用ダンパーユニットとを備え、前記冷凍室が、この冷凍室を正面から見て左右に区画する仕切壁を有し、前記冷凍室用ダンパーユニット、この冷凍室用ダンパーユニットの駆動部の一部、又は冷凍室用ダンパーユニットの駆動部の全部を、前記仕切壁の冷凍室を正面から見た投影空間内に配置することで達成される。
【0023】
即ち、ダンパーユニット又はダンパーを駆動する駆動部を有効内容積を縮めない仕切部材の投影面積内に配設したことにより、有効内容積を大きく出来る。
【0024】
【発明の実施の形態】
以下、本発明の詳細を図に示す実施の形態で説明する。図1は本発明の第1の実施例を示す冷蔵庫のダンパーユニットの配置を示す概略要部正面図である。図2は本発明の第1・第2の実施例の冷蔵庫の冷凍室の扉を開放した状態の正面図である。図3aは図1のIIIa−IIIa断面図であり冷凍室用である第2のダンパーユニット周囲の構成を示す。図3bは図1のIIIb−IIIb断面図であり製氷室上流側に配置された第三のダンパーユニット周囲の構成を示す。図4は図1に示す第1及び第2のダンパーユニット等の関係を示す縦断面図である。図5は本発明の第2の実施例の冷蔵庫の各仕切部材と各ダンパーユニットの駆動部との関係を示す概略正面図である。図6は第1・第2の実施例に共通して左右に区画された冷凍室の縦仕切部材に設けた貫通穴を示す概略要部断面正面図である。図7は第1・第2の実施例に共通して左右に区画された冷凍室の縦仕切部材に設けた貫通穴を示す要部縦断面図である。
【0025】
各図において、1は冷蔵庫、2は冷蔵室、3は右側冷凍室、4は左側冷凍室、5は冷蔵室用ダンパーユニット(第一のダンパーユニット)、6は冷凍室用ダンパーユニット(第二のダンパーユニット)であるが主として右側冷凍室3の上方に位置する急速冷凍コーナー17への冷却空気の吐出量を制御している。6aはダンパーユニット6の吸込口で、6bはダンパーである。7は同じく冷凍室用のダンパーユニット(第三のダンパーユニット)であり、主として左側冷凍室4の上方に位置するアイスメーカーコーナー18への冷却空気の吐出量を制御している。7aはダンパーユニット7の吸込口で、7bはダンパーである。又、ダンパーユニット6および7は冷凍室内に設置された温度センサーの働きと扉に設けた(図示せず)温度制御操作パネルの指示により、各々の冷凍室の温度制御も行なっている。
【0026】
8は蒸発器、9は冷却空気を循環させる送風機、10は冷蔵室用冷気通風路、11は冷蔵室用戻り冷気通風路、12は冷凍室用戻り冷気通風路、13は野菜室、14は冷凍室を左右に分割する冷凍室縦仕切部材、15は冷凍室温度を感知するセンサー、16は横仕切部材、17は急速冷凍コーナー、18はアイスメーカーコーナー、19は冷凍室食品収納容器である。20は圧力室で、送風機9の羽根9aが収納されており、且つ上記各ダンパーユニット5、6、7の冷却空気吸入口が開口している。21及び23は冷気吐出通路、21a及び23aは冷気導入部で、冷気吐出通路21又は23に一体に形成されており、冷気吐出通路21又は23に流れる冷気を効率よく導入するためのものである。22及び24は冷気吐出口、25は圧縮機である。
【0027】
図2に示すように、本願発明の実施例である冷蔵庫1は、上方より冷蔵室2、野菜室13、冷凍室を備えており、冷凍室は、右側冷凍室3と左側冷凍室4とに分かれ、その内部に冷凍室食品収納容器19を複数配置している。また、右側冷凍室3の最上段には、急速冷凍コーナー17を設置し、左側冷凍室4の最上段には、アイスメーカーコーナー18を設置している。更に、庫内の温度差が大きい野菜室13と冷凍室との間には、断熱材である横仕切部材16を配置している。
【0028】
図1は、第1の実施例を示す冷蔵庫のダンパーユニットの配置を示す概略要部正面図であり、羽根9aを備えた送風機9の回転中心軸よりも下方に冷凍室用ダンパーユニット6、7を備えている。蒸発器8により冷却された冷却空気は、送風機9が旋回することにより、冷気吐出通路21、23を通過して冷凍室へと流入し、特に冷却吐出通路23を通過した冷気は、アイスメーカーコーナー18(図2参照)へと集中的に冷気を供給する。冷凍室を冷却した空気は、冷凍室用戻り冷気通風路12より流入し、蒸発器8にて再び冷却され循環する。尚、冷蔵室用ダンパーユニット5は、冷凍室よりも上に設置されている冷蔵室2及び野菜室13(図2参照)へと冷却空気を供給する。
【0029】
このものにおいて急速に製氷する場合は、冷蔵室用ダンパーユニット5を閉め、冷蔵室2のプラス温度の冷却空気が循環しないようにし、同時に急速冷凍コーナー17に冷却空気を送風するダンパーユニットも閉じて、アイスメーカーコーナー18へと冷却空気を送風するダンパーユニットのみ開くようにする。このようにすると、蒸発器8で冷却された約マイナス27℃の冷却空気が、直接集中的に製氷皿18aに吹付けられるので、製氷皿18aの表面熱伝達率が上昇し、素早く熱を奪い製氷時間が短縮される。又同様に、素早く冷凍したい貯蔵品がある場合には、冷蔵室用ダンパーユニット5と冷凍室用ダンパーユニット7を閉じて、急速冷凍コーナー17へと冷却空気を送風する冷凍室用ダンパーユニット6を開けることで、ホームフリージングの時間が短かくなり、短時間で冷凍食品を作ることができる。
【0030】
更に、冷凍室用ダンパーユニット6、7の冷却空気の吸込口を、図1及び図3に示すように、送風機9の羽根9aの中心より下になるように配設することにより、蒸発器8で冷却され重くなった空気を上方に押し上げる(持ち上げる)ように送風する必要がなくなり、送風機9の圧損が少なくなってエネルギーを要せず、消費電力量を低減した冷蔵庫を提供することができる。また、冷凍室用ダンパーユニット6の冷却空気の吸込口が前記送風機9と重ならないことにより、その分だけ冷凍室の奥行きが小さくなるのを抑制できるので、冷凍室の収納容積が小さくなるのを抑制できる。
【0031】
また、図1に示す冷蔵庫は、急速冷凍コーナー17及びアイスメーカーコーナー18への冷気の流れを独立して調整するダンパーユニットを夫々設け、このダンパーユニットを左右方向に並べて配置することによって、冷凍室の最上部に配置された急速冷凍コーナー17又はアイスメーカーコーナー18のいずれにも送風機9からの距離が短くなり、送風機9からの冷却空気をいずれのコーナーの上方部分にも短い距離で集中的に供給できることにより、より短時間に製氷や食品のホームフリージングができる。
【0032】
図3(a)を用いて、冷凍室用ダンパーユニット6について詳細に述べると、ダンパー6bは、急速冷凍運転する場合に、急速冷凍コーナー17へと冷却空気を導く冷気導入部21aと、その先端が対向して近接するように位置する。また、冷気導入部21aと冷凍室用ダンパーユニット6との位置関係は、ダンパー6bの支点が風上になるように配置し、冷凍室用ダンパーユニット6のダンパー6bの開度を選択することにより、例えば実施例ではダンパー6bの開度を約45°位下方に傾斜する位置で冷気導入板21aとダンパー6bの先端が対向して近接させることで、冷凍室用ダンパーユニット6の吸込口6aに入った冷却空気のほぼ全てが冷気導入部21aを介して冷気吐出口22より急速冷凍コーナー17に吐出される。
【0033】
また、図3(b)を用いて、冷凍室用ダンパーユニット7について詳細に述べると、ダンパー7bは、急速冷凍運転する場合に、製氷皿18aとへと冷却空気を導く冷気導入部23aと、その先端が対向して近接するように位置する。また、冷気導入部23aと冷凍室用ダンパーユニットとの位置関係は、ダンパー7bの支点が風上になるように配置し、ダンパー7bの開度を選択することにより、冷凍室用ダンパーユニット7の吸込口7aに入った冷却空気のほぼ全てが冷気導入部23aを介して冷気吐出口24よりアイスメーカーコーナー18に吐出される。 このように、冷凍室内にアイスメーカーの配置されたアイスメーカーコーナー18又は急速冷凍コーナー17と、冷凍室用ダンパーユニットからの冷却空気を導入するための冷気導入部21a又は23aとを有し、冷凍室用ダンパーユニット6又は7がアイスメーカーコーナー18又は急速冷凍コーナー17への送風を調整し、冷凍室用ダンパーユニット6及び7のダンパー6b及び7bの開閉角度が調整若しくは選択可能であり、これらのダンパーの先端が前記冷気導入部21a又は23aの先端に対向して近接するように開閉角度が調整若しくは選択される構成にしたことにより、製氷又は食品をホームフリージングする際に、ダンパーの先端が前記冷却空気の冷気導入部の先端に対向させて、ダンパーユニットの吸込口を経由した多くの冷却空気を集中的に吹き付けるようにして短時間で製氷又は冷凍させることができる。
【0034】
図4は、冷蔵室用ダンパーユニットと、冷凍室用ダンパーユニットとの位置関係を示す、冷蔵庫の縦断面図である。急速冷凍コーナー17の下に位置する右側冷凍室3の各冷凍室食品収納容器19に流速の速い冷却空気を送り込む場合には、冷凍室用ダンパーユニット6を全開にして、冷凍室用ダンパーユニット6の下に継がる冷気吐出通路21を、下流に行くほどに通路の断面積を狭くして冷気吐出通路21内の風速が低下するのを防ぐ。即ち、各冷凍室食品収納容器19には、流速の速い冷却空気を流入させるために、冷気吐出通路21の各冷凍室食品収納容器への冷気吐出口22毎に冷却空気の冷気導入部21aを設け、各冷気導入部21aを境に風量が減じた分通路を狭めるようにする。尚、冷気吐出通路21を下流に行くにつれて狭めた分右側冷凍室内を広くし有効内容積を広げて容器の内容積も大きくする。
【0035】
図5は、本発明の第2の実施例を示す、冷蔵庫の各仕切部材と各ダンパーユニットの駆動部との関係を示す概略正面図である。各ダンパーユニット5、6、7の駆動部は、冷蔵室2と野菜室13とを区画する横仕切部材16、及び、右側冷凍室3と左側冷凍室4とを区画する冷凍室縦仕切部材14の、冷蔵庫1を正面から見た際の投影面積内に配置したり、図3に示すように、冷蔵庫1を正面から見た際の製氷皿18aの投影面積内に配置したりすることで、各ダンパーユニットの庫内への出っ張りを少なくし、有効内容積を大きくできるようにしている。
【0036】
図6及び図7に示すように、冷凍室縦仕切部材14は、貫通孔14aを備えており、この貫通孔14aに冷凍室内の庫内温度制御を行う際に用いる温度測定用のセンサー15を有してる。センサー15は、貫通孔14内に設置されていることから、左右の冷凍室にて共用化することができ、部品点数を低減することで製造コストを下げることができると共に、左右の冷凍室温度の均一化を図れる。
【0037】
図3aに示す急速冷凍コーナー17が優先の冷凍室用ダンパーユニット6と、図3bに示すアイスメーカーの冷却が優先の冷凍室用ダンパーユニット7とを配置して、各ダンパーユニットの下方にアイスメーカーコーナー18及び急速冷凍コーナー17を配置したので、各々の通風路を最短で簡単な構造で継ぐことが出来たので部品代が安く組立も短時間で出来る、安い冷蔵庫を提供することができる。
【0038】
以上詳細に説明したように、各実施例によれば、急速に冷却したい部屋のダンパーユニットを開き他の部屋のダンパーユニットを閉じる方式により、冷却空気が集中的に吐出されるので風量が増加し、表面熱伝達率が大きくなり早く冷やすことができ、製氷時間が短かくなり、又ホームフリージングの時間も短かくなる。そして、ホームフリージングの時間が短いことによって、食品は、その美味しさを従来よりも増した状態でホームフリージングでき、保存期間も長くできる。
【0039】
また、急速冷凍コーナーやアイスメーカーコーナーへの冷却空気を吐出するダンパーユニットは、送風機の羽根の中心より低い位置に配設したので、蒸発器で冷却された重たい冷却空気を送風機で持ち上げることなく、スムーズに冷凍室へと流入し、送風機がその分エネルギーを使う必要がなくなって省電力化できる。
【0040】
冷却空気が流れる通路は、下流に行くほどその通路断面積が小さくなるようにしたことにより、各冷凍室食品収納容器又は棚上に風速の劣ることがない冷却空気を吐出することができ、各容器を均一に冷却することができる。
【0041】
各部屋へ吐出する風量を加減するダンパーユニットの駆動部は、冷蔵庫の各部屋の間仕切部材の投影面内に配置し、若しくはアイスメーカーが優先のダンパーユニットの駆動部を冷蔵庫の前方から見て、アイスメーカーの投影面積内に配置したので、ダンパーユニットの駆動部が冷凍庫内の空間を小さくするのを抑制でき、その分冷蔵庫内の有効内容積を大きくできる。
【0042】
【発明の効果】
本発明によれば、庫内の有効内容積を広くし、消費電力を低減させ、使い勝手の良い冷蔵庫を提供することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a refrigerator.
[0002]
[Prior art]
Conventional refrigerators, for example, when the operation of the compressor is stopped, by opening the damper unit for the freezing room, by operating the blower, to blow the frost attached to the evaporator to the refrigerator compartment while sublimating frost In some refrigerators, the humidity in the refrigerator compartment is increased so that vegetables and other foods retain moisture and maintain freshness.
[0003]
In this conventional refrigerator, a damper unit for a freezing room is arranged in front of the blower (in the depth direction of the freezing room), so that cooling air is blown out to the entire inside of the freezing room. Such a refrigerator is described in, for example, JP-A-2001-241825.
[0004]
[Problems to be solved by the invention]
However, in the above-described conventional refrigerator, since the damper unit for the freezing room is disposed in front of the blower, the dimension in the depth direction increases, and the storage volume in the freezer room decreases. Further, the conventional refrigerator has a possibility that the amount of air discharged to the freezer compartment decreases due to an increase in air resistance. Further, in the conventional refrigerator, since the damper unit for controlling the air circulation of the freezing room is located in front of the blower, the cool air cooled by the evaporator and becoming heavier than before cooling is temporarily discharged above the damper of the damper unit. It is necessary to blow the air so as to lift up to the suction port of the damper unit located at the position (1), and the blower needs extra energy by that much, and there is a problem that the power consumption is increased.
[0005]
In view of the above, a first object of the present invention is to provide a refrigerator that suppresses a decrease in the storage volume of a freezing room, further reduces pressure loss of a blower, and reduces power consumption.
[0006]
In addition, since the above-mentioned conventional refrigerator has a configuration in which cooling air is blown out to the entire freezing compartment, when the internal volume of the freezing compartment is increased, it is possible to shorten the ice making time and freeze food in a short time. Have difficulty. A second object of the present invention is to provide a refrigerator capable of home-freezing ice or food in a short time by intensively discharging cold cooling air to an ice maker or a part to be rapidly frozen when home-freezing ice or food. Is to provide.
[0007]
Furthermore, in order to make the temperature distribution in the freezer compartment uniform when the freezer compartment volume is increased, there is a method of solving the problem by providing many cool air outlets for discharging cool air into the freezer compartment. If the cold air discharge port is provided, the effective internal volume of the inside of the freezing chamber will be reduced.
[0008]
In addition, the cool air discharged from the cool air discharge port far from the blower (the cool air discharge port located downstream among the plurality of cool air discharge ports) has a reduced flow rate due to passage resistance, and the discharge flow rate is slowed down. Even if a plurality of cold air discharge ports are provided, there is a possibility that the temperature distribution in the freezer compartment cannot be sufficiently made uniform.
[0009]
A third object of the present invention is to reduce the effective internal volume in the freezer compartment when a plurality of cool air outlets are provided, and to reduce the discharge flow rate from the downstream cool air outlet to the upstream cool air outlet. An object of the present invention is to provide a refrigerator in which the temperature distribution in the freezer compartment is made uniform without significantly differing from the discharge flow velocity.
[0010]
Furthermore, when the damper unit is provided, the volume of the damper unit or the volume of the drive unit for driving the damper is a dead space in the refrigerator, and there is a problem that the effective internal volume is reduced. A fourth object of the present invention is to provide a refrigerator in which a damper unit or a driving unit for driving the damper is arranged at a position where the effective internal volume is not reduced, and the effective internal volume can be increased.
[0011]
That is, an object of the present invention is to provide an easy-to-use refrigerator in which the effective internal volume in the refrigerator is widened, power consumption is reduced.
[0012]
[Means for Solving the Problems]
The first object is to provide a refrigerating compartment, a freezing compartment located below the refrigerating compartment, one evaporator, and one blower for blowing cooling air exchanged with the evaporator. A freezer compartment damper unit for controlling airflow to the freezer compartment of the cooling air; and a refrigerating compartment damper unit for controlling the airflow of the blown cooling air to the refrigerating compartment, wherein the cooling air of the freezer compartment damper unit is provided. Is achieved by positioning the suction port of the air blower not to overlap with the blower but below the rotation center axis of the blower.
[0013]
That is, the refrigerator having the above-described configuration suppresses the storage volume of the freezer compartment from being reduced, and eliminates the need to blow heavy cold air so that the blower lifts upward, thereby reducing the pressure loss of the blower and reducing power consumption. Has been reduced.
[0014]
The second object is that the freezing compartment is divided into left and right sides when the freezing compartment is viewed from the front, and an ice making compartment arranged at the top of one of the right and left of the freezing compartment partitioned by the partitioning wall. Alternatively, the present invention is attained by providing a quick-freezing room, and the damper unit for the freezing room is a damper unit that controls air blowing to the ice making room or the quick-freezing room.
[0015]

[0016]
A second object is that a freezer compartment is provided at a partition wall which partitions the freezer compartment from left to right as viewed from the front, and an ice making device arranged at the uppermost one of the right and left of the freezer compartment partitioned by the partition wall. Room, and a quick-freezing room disposed at the top of the other freezing room, a damper unit for controlling the air flow to the ice making room, and a damper unit for controlling the air flow to the quick-freezing room, It can also be achieved by arranging them side by side. In the refrigerator having such a configuration, the distance from the blower to both the ice making room and the quick freezing room arranged at the uppermost portion of the freezing room is shortened by arranging the damper units side by side in the left-right direction. Since cooling air can be intensively supplied over a short distance, freezing can be performed in a shorter time.
[0017]
A second object is to provide a refrigerating room, a freezing room, an evaporator for cooling the air in the refrigerator, a blower for blowing cooling air that has exchanged heat with the evaporator, and a cooling system for blowing the cooling room. A refrigerating room damper unit for controlling the amount of air blown, and a freezing room damper unit for controlling the amount of cooling air blown to the freezing room, wherein the freezing room is an ice making room or a quick freezing room. And a cool air introduction unit for introducing cooling air whose flow rate is adjusted by the freezing room damper unit, and the damper of the freezing room damper unit stops at its tip at an angle facing the cool air introduction unit. Can be achieved.
[0018]
That is, in such a refrigerator, when ice making or home freezing of food, the tip of the damper is opposed to the tip of the cool air introduction part of the cooling air, and a large amount of cooling air passing through the suction port of the damper unit is concentrated. To make ice or freeze in a short time.
[0019]
Further, the second purpose is that the freezer compartment damper unit positions the suction port of the cooling air below the rotation center axis of the blower so that the heavy cooling air cooled by the evaporator is lifted by the blower. The air can be blown smoothly.
[0020]
The third object is that a freezing compartment is provided with a plurality of storage containers, a cool air introduction portion for introducing cooling air from the damper unit into the storage container or the storage container, and a cooling air introduction portion between the damper unit and the cold air introduction portion. And a cold air discharge passage having a cross-sectional area in the passage that becomes smaller toward the downstream side.
[0021]
That is, the refrigerator having such a configuration prevents the flow rate in the cool air discharge passage from decreasing due to the fact that the inside of the cool air discharge passage is narrower toward the downstream, and the flow rate on the container or shelf for storing the stored food of each stage. In order to allow the high-speed air to flow in, a cool air introduction unit is provided for introducing cooling air to each container or each storage space, and the cool air discharge passage is narrowed by the amount of air flow reduced at the cool air introduction unit. Thereby, a decrease in the flow velocity of the cooling air can be suppressed. In addition, the depth of the freezing compartment can be increased by an amount corresponding to the narrowing of the cool air discharge passage, so that the effective internal volume can be increased.
[0022]
A fourth object is to provide a refrigerating room, a freezing room, an evaporator for cooling air in the refrigerator, a blower for blowing cooling air that has exchanged heat with the evaporator, and a cooling air blown to the refrigerating room. A refrigerator compartment damper unit for controlling the amount of blown air, and a freezer compartment damper unit for controlling the amount of cooling air blown to the freezing room, wherein the freezing room is viewed from the front of the freezing room. The partition wall is divided into left and right, the freezer compartment damper unit, a part of the drive unit of the freezer compartment damper unit, or the entire drive unit of the freezer compartment damper unit, the freezer compartment of the partition wall This is achieved by arranging in a projection space viewed from the front.
[0023]

The refrigerator compartment damper unit 5 supplies cooling air to the refrigerator compartment 2 and the vegetable compartment 13 (see FIG. 2) installed above the freezer compartment.
[0029]
In this case, when making ice quickly, the damper unit 5 for the refrigerator compartment is closed to prevent the cooling air of the plus temperature of the refrigerator compartment 2 from circulating, and at the same time, the damper unit for blowing the cooling air to the quick freezing corner 17 is also closed. Only the damper unit for blowing the cooling air to the ice maker corner 18 is opened. In this way, the cooling air at about minus 27 ° C. cooled by the evaporator 8 is directly and intensively blown onto the ice tray 18a, so that the surface heat transfer coefficient of the ice tray 18a increases and heat is quickly taken away. Ice making time is reduced. Similarly, when there is a storage item that the user wants to freeze quickly, the refrigerator compartment damper unit 5 and the refrigerator compartment damper unit 7 are closed, and the refrigerator compartment damper unit 6 that blows the cooling air to the quick freezing corner 17 is closed. By opening, the time of home freezing is shortened, and frozen food can be made in a short time.

Are positioned so as to face each other. In addition, the positional relationship between the cold air introducing portion 21a and the freezer compartment damper unit 6 is determined by arranging the fulcrum of the damper 6b on the windward side and selecting the opening degree of the damper 6b of the freezer compartment damper unit 6. For example, in the embodiment, the cold air introduction plate 21a and the tip of the damper 6b are opposed to each other at a position where the opening degree of the damper 6b is inclined downward by about 45 ° so as to be close to the suction port 6a of the freezing room damper unit 6. Almost all of the entered cooling air is discharged from the cool air discharge port 22 to the quick freezing corner 17 through the cool air introduction part 21a.
[0033]
Further, the damper unit 7 for a freezer compartment will be described in detail with reference to FIG. 3B. The damper 7b includes a cold air introduction part 23a that guides cooling air to the ice tray 18a when performing a rapid freezing operation. The tips are positioned so as to face each other and to approach each other. In addition, the positional relationship between the cool air introduction part 23a and the freezer compartment damper unit is such that the fulcrum of the damper 7b is disposed on the windward side, and the opening degree of the damper 7b is selected. Almost all of the cooling air that has entered the suction port 7a is discharged to the ice maker corner 18 from the cool air discharge port 24 via the cool air introduction part 23a. As described above, the freezing room has the ice maker corner 18 or the quick freezing corner 17 where the ice maker is arranged, and the cold air introduction part 21a or 23a for introducing the cooling air from the freezing room damper unit. The room damper unit 6 or 7 adjusts the air flow to the ice maker corner 18 or the quick freezing corner 17, and the opening and closing angles of the dampers 6b and 7b of the freezer room damper units 6 and 7 can be adjusted or selected. When the opening and closing angle is adjusted or selected so that the tip of the damper is opposed to and close to the tip of the cold air introduction part 21a or 23a, the tip of the damper is used when home-freezing ice or food. A lot of cooling air is passed through the suction port of the damper unit, facing the tip of the cool air introduction section. Cooling air can be ice or frozen in a short period of time so as to blow intensively.
[0034]
FIG. 4 is a longitudinal sectional view of the refrigerator, showing the positional relationship between the refrigerator compartment damper unit and the freezer compartment damper unit. When cooling air having a high flow rate is fed into each freezing room food storage container 19 of the right freezing room 3 located below the quick freezing corner 17, the freezing room damper unit 6 is fully opened and the freezing room damper unit 6 is opened. The cross-sectional area of the cool air discharge passage 21 connected to the lower portion of the cool air discharge passage 21 is made narrower toward the downstream, thereby preventing the wind speed in the cool air discharge passage 21 from decreasing. That is, in order to allow the cooling air having a high flow rate to flow into each freezing room food storage container 19, a cooling air introduction unit 21 a for each cooling air discharge port 22 to each freezing room food storage container of the cooling air discharge passage 21 is provided. The passage is narrowed by the amount of reduced airflow at each cold air inlet 21a. It should be noted that the right freezer compartment is widened by an amount corresponding to the narrowing of the cold air discharge passage 21 toward the downstream, so that the effective internal volume is increased and the internal volume of the container is also increased.
[0035]
FIG. 5 is a schematic front view showing the relationship between each partition member of the refrigerator and the drive section of each damper unit, showing the second embodiment of the present invention. The drive units of the damper units 5, 6, 7 are a horizontal partition member 16 for partitioning the refrigerator compartment 2 and the vegetable compartment 13, and a vertical partition member 14 for partitioning the right freezer compartment 3 and the left freezer compartment 4. By arranging the refrigerator 1 within the projection area when viewed from the front, or as illustrated in FIG. 3, by arranging it within the projection area of the ice tray 18a when viewing the refrigerator 1 from the front, The protrusion of each damper unit into the refrigerator is reduced, so that the effective internal volume can be increased.
[0036]
As shown in FIG. 6 and FIG. 7, the freezing compartment vertical partition member 14 has a through hole 14 a, and a temperature measuring sensor 15 used when controlling the temperature inside the freezer compartment is provided in the through hole 14 a. I have. Since the sensor 15 is installed in the through hole 14, the sensor 15 can be shared by the left and right freezer compartments, the number of parts can be reduced, the manufacturing cost can be reduced, and the left and right freezer compartment temperature can be reduced. Can be made uniform.
[0037]
The freezing compartment damper unit 6 in which the quick freezing corner 17 shown in FIG. 3A is prioritized, and the freezer compartment damper unit 7 shown in FIG. 3B in which cooling of the ice maker is prioritized are arranged, and the ice maker is provided below each damper unit. Since the corner 18 and the quick freezing corner 17 are arranged, each ventilation path can be connected with a shortest and simple structure, so that it is possible to provide an inexpensive refrigerator in which parts cost is low and assembly can be performed in a short time.
[0038]
As described in detail above, according to each embodiment, the cooling air is intensively discharged by opening the damper unit of the room to be rapidly cooled and closing the damper unit of the other room, so that the air volume increases. In addition, the surface heat transfer coefficient is increased and cooling can be performed quickly, and the ice making time is shortened, and the home freezing time is also shortened. Since the home-freezing time is short, the food can be home-freezed in a state in which the taste is increased more than before, and the storage period can be prolonged.
[0039]
In addition, the damper unit that discharges cooling air to the quick freezing corner and ice maker corner is located at a position lower than the center of the blade of the blower, so the heavy cooling air cooled by the evaporator is not lifted by the blower, The air flows smoothly into the freezer compartment, and the fan does not need to use the energy correspondingly, thereby saving power.
[0040]
The passage through which the cooling air flows is such that the passage cross-sectional area becomes smaller toward the downstream, so that the cooling air can be discharged onto the freezing room food storage containers or shelves without inferior wind speed, The container can be cooled uniformly.
[0041]
The drive unit of the damper unit that adjusts the amount of air discharged to each room is arranged in the projection plane of the partition member of each room of the refrigerator, or the ice maker sees the drive unit of the damper unit with priority from the front of the refrigerator, Since it is arranged within the projected area of the ice maker, it is possible to suppress the drive unit of the damper unit from reducing the space in the freezer, and it is possible to increase the effective internal volume in the refrigerator accordingly.
