Description

【0001】
【発明の属する技術分野】
本発明は、冷凍冷蔵庫に係り、より詳しくは、熱交換量が増大し性能も向上した冷凍冷蔵庫に関するものである。
【0002】
【従来の技術】
図13は従来の冷凍冷蔵庫の本体下部の一例を示す縦断面である。図に示すように、凝縮器2は、伝熱管9を貫通させてこれを支持するフィン部7(高さh)とその下方に隣接する空間部8(高さA)とによって形成され、これらにより風路を構成している。このとき、空間部8の高さAは例えばフィン部7の高さhの1/5程度に構成されている。
そして、空気がフィン部7と空間部8からなる風路を通過して、凝縮器2内の冷媒と熱交換を行う。
【0003】
【発明が解決しようとする課題】
上記のように構成した冷凍冷蔵庫の凝縮器2によれば、空気が通過できる部分はフィン部7の高さの1/5程度しかないので、空気の圧力損失が大きく空気流量が少なくなって、フィン部7における熱交換量が減少する。このため、フィン部7から流出していく空気温度が上昇して圧縮機を有効に冷却することができない。また、空間部8が低いためフィン部7に埃が詰まって閉塞し、空気が流れにくくなってフィン部7の性能が著しく低下する。
【0004】
本発明は上記のような課題を解決するためになされたもので、空気の圧力損失を抑えて空気の流量を増し、熱交換量を増大させると共に性能を向上させることができる凝縮器を備えた冷凍冷蔵庫を得ることを目的とする。
【0005】
【課題を解決するための手段】
本発明にかかる冷凍冷蔵庫は、次のように構成したものである。
(1) 空気をファンによって凝縮器から圧縮機に送って該圧縮機等を冷却する冷凍冷蔵庫において、伝熱管を貫通させて支持するフィン部と該フィン部に隣接する空間部とからなる風路によって前記凝縮器を形成し、前記空間部を前記フィン部の下部に隣接させると共に、該空間部の高さを前記フィン部の高さの1/5より大きくかつ該フィン部の高さ以下に構成した。
(2) 上記(1)の冷凍冷蔵庫において、空間部をフィン部の下部に隣接させたことに代えて、該空間部を前記フィン部の上部に隣接させた。
【0006】
(3) 空気をファンによって凝縮器から圧縮機に送って該圧縮機等を冷却する冷凍冷蔵庫において、伝熱管を貫通させて支持するフィン部と該フィン部に隣接する空間部とからなる風路によって前記凝縮器を形成し、前記空間部を前記フィン部の上部及び下部に隣接させると共に、該上部及び下部の空間部の高さの和を前記フィン部の高さの1/5より大きくかつ該フィン部の高さ以下に構成した。
(4) 空気をファンによって凝縮器から圧縮機に送って該圧縮機等を冷却する冷凍冷蔵庫において、伝熱管を貫通させて支持するフィン部と該フィン部に隣接する空間部とからなる風路によって前記凝縮器を形成し、前記空間部の高さを前記フィン部の高さの1/5より大きくかつ該フィン部の高さ以下に構成すると共に、前記フィン部の前記空間部と隣接する側の伝熱面積を広くした。
【0007】
(5) 空気をファンによって凝縮器から圧縮機に送って該圧縮機等を冷却する冷凍冷蔵庫において、伝熱管を貫通させて支持するフィン部と該フィン部に隣接する空間部とからなる風路によって前記凝縮器を形成し、前記空間部の高さを前記フィン部の高さの1/5より大きくかつ該フィン部の高さ以下に構成すると共に、前記ファンに近くなるほど前記フィン部の間隔を狭くした。
【0008】
(6) 上記(1)乃至(5)のいずれかの冷凍冷蔵庫において、フィン部に切り起こしを設けて空気の流れを乱し伝熱を促進するようにした。
(7) 上記(1)乃至(6)のいずれかの冷凍冷蔵庫において、密閉容器内に、駆動源とこれによって駆動される圧縮機構部、冷媒を吸い込む吸入管、及び圧縮機構部によって圧縮された冷媒を吐出する吐出管を備え、密閉容器内を吐出圧力に保持した高圧シェルタイプの圧縮機を設けた。
【0009】
(8) 上記(1)乃至(7)のいずれかの冷凍冷蔵庫において、凝縮器と圧縮機を対向して配設し、冷却用のファンを圧縮機の横方向に設けて空気流を凝縮器の正面からファンを介して圧縮機の側面に流すようにした。
(9) 上記(8)の冷凍冷蔵庫において、ファンをプロペラファン又は多翼ファンとした。
【0010】
(10) 上記(1)乃至(7)のいずれかの冷凍冷蔵庫において、凝縮器と圧縮機を対向して配設しこれらの間にファンを設けて空気流を凝縮器の正面からファンを介して圧縮機の正面に流すようにした。
(11) 上記(10)の冷凍冷蔵庫において、ファンをクロスフローファンとした。
【0011】
【発明の実施の形態】
実施の形態1
図1は冷凍冷蔵庫の一例を示す正面図であり、図2は図1で示した冷凍冷蔵庫のA−A断面図、図3は図2のB−B断面図である。図に示すように、1は冷凍冷蔵庫の本体底部であり、2,3,4はそれぞれ本体底部1に取り付けた凝縮器、冷却用のプロペラファン及び圧縮機である。
【0012】
より詳しくは、凝縮器2の後側(図2の上側)に圧縮機4が配設され、圧縮機4の側方(図2の左側)には冷却用のプロペラファン3が配設され、凝縮器2と圧縮機4の間は隔壁5によって仕切られている。6aはプロペラファン3の上流側に設けた空気導入口であり、6bは圧縮器3の下流側に設けた空気流出口である。
こうして、凝縮器2を通過した空気流はプロペラファン3の方向に流れ、空気導入口6aから入る空気流と一体となって圧縮機4方向に向かい、空気流出口6bから外部に流出するようになっている。
【0013】
次に、凝縮器2について詳述すると、本体底面1aを有し前後方向(図2の下から上への方向)に空気を通すための風路を形成し、この風路の上部は高さがhで左右方向に交互に凹凸状をなし、伝熱面である上面aと下面bが平面状で等面積のフィン部7によって構成され、風路の下部はフィン部7に隣接する高さAの空間部8によって構成されている。そして、フィン部7には、両側端でU字状に折り曲げられて冷媒が流れる伝熱管9が凹凸部の側面10を貫通した状態で取り付けられている。
上記のように構成した凝縮器2において、その空間部8の高さAは、フィン部6の高さhの1/5よりも大きく、フィン部6の高さh以下の大きさに形成されている。
【0014】
図4は、凝縮器2の空間部8の高さAと風量増加割合(%)、空間部8の高さAと熱交換量増加割合(%)、空間部8の高さAと凝縮器流出温度低下割合(%)の関係を示す説明図で、空間部8の高さAを0からフィン部7の高さであるhまでとって、同一のプロペラファンとファンモータを用いて試験をした結果を示すものである。
【0015】
図からわかるように、空間部8の高さAをフィン部7の高さhの1/5よりも大きくフィン部7と同じ高さhの大きさまでとるときは、空間部8の高さAの大きさを0からフィン部7の高さhの1/5の大きさまでとった従来技術の場合と比較して、フィン部7への空気流量が増加し、凝縮器2における熱交換量が増加する一方、凝縮器流出温度は低下する。従って、上述したように、本発明では、空間部8の高さAを、フィン部7の高さhの1/5よりも大きくフィン部7の高さhまでの大きさとした。
【0016】
上記のように構成した実施の形態1の作用を説明する。空気はフィン部7と空間部8からなる凝縮器2の風路前方からイ方向に入り、フィン部7において伝熱管9と熱交換を行なって凝縮器2の後方から出る。この際、プロペラファン3に近い側の空気流はそのままロ方向に流れてプロペラファン3に向い、プロペラファン3から離れた側の空気流は隔壁5に沿ってハ方向に移動したのちプロペラファン3に向かう。そして、これらの空気流は空気導入口6aからニ方向に流入する空気流と一体となってプロペラファン3から圧縮機4に向かってホ方向に流れ、圧縮機4を冷却して空気流出口6bからヘ方向に流出する。
【0017】
なお、上記の説明において、フィン部7は交互に凹凸状をなしその上面aと下面bが平面状である場合を示したが、波型形状やその他の形状であってもよい。また、プロペラファン3が図の左側に位置した場合を示したが、図の右側又は中央部に位置するようにしてもよい。
実施の形態1によれば、空間部8の高さAをフィン部7の高さhの1/5の大きさからフィン部7の高さhまでの大きさに構成したので、フィン部7の空気流量が増加して凝縮器2の熱交換量が増大し流出温度が低下するので、圧縮機4を十分に冷却することができる。また、凝縮器2の空間部8が広くなるので、若し、フィン部7に埃が詰まったとしても空気の流量が低下せず、凝縮器2の性能低下が抑えられて信頼性が向上する。
【0018】
実施の形態2
図5は図1の冷凍冷蔵庫を図2のB−B方向に切断した縦断面である。実施の形態1では空間部8の上部にフィン部7を設けて凝縮器2を構成したが、実施の形態2では、フィン部7の上部に空間部8を設けて凝縮器2を構成したものである。この場合、空間部8の高さAは、凝縮器2のフィン部7の高さhの1/5の大きさからフィン部7の高さhまでの大きさになるようにしてある。その他の、構成、作用、効果は実施の形態1で示した場合と同様なので、説明を省略する。
【0019】
実施の形態3
図6は図1の冷凍冷蔵庫を図2のB−B方向に切断した縦断面である。実施の形態1では空間部8の上部にフィン部7を設けて凝縮器2を構成したが、実施の形態3では、フィン部7の上部及び下部に空間部8a,8bを設けて凝縮器2を構成したものである。この場合、空間部8の高さAは、フィン部7の上部と下部に設けた各々の空間部8a,8bの高さA1とA2の和となり、この高さAが凝縮器2のフィン部7の高さhの1/5の大きさからフィン部7の高さhまでの大きさになるようにしてある。その他の、構成、作用、効果は実施の形態1で示した場合と同様なので、説明を省略する。
【0020】
実施の形態4
図7は図1の冷凍冷蔵庫を図2のB−B方向に切断した縦断面である。実施の形態1ではフィン部7の伝熱面である上下面a,bを等面積にして左右に等間隔に配設し、その下部に空間部8を設けて凝縮器2を構成したが、実施の形態4では、フィン部7の下面bの面積を広くし上面aの面積を狭くして左右に等間隔に配設し、その下部に空間部8を設けて凝縮器2を構成したものである。このとき、空間部8の高さAは、フィン部7の高さhの1/5の大きさからフィン部7の高さhまでの大きさになるようにしてある。その他の、構成、作用は実施の形態1で示した場合と同様なので、説明を省略する。
実施の形態4によれば、空間部8に接するフィン部7の伝熱面である下面bを広くしたので、フィン部7の伝熱が促進されて熱交換量が増大する。
【0021】
実施の形態5
図8は図1の冷凍冷蔵庫をA−A方向に切断した断面図である。実施の形態1ではフィン部7の上下面a,bを等面積にして左右に等間隔に配設し、その下部に空間部8を設けて凝縮器2を構成したが、実施の形態8ではフィン部7の上下面a,bの伝熱面積と間隔を風路圧損に合わせて調整したものである。
すなわち、プロペラファン3に近付くほど(図の左側にいくほど)、フィン部7の上下面a,bの面積を狭くしてフィン部7の間隔が狭くなるように形成し、プロペラファン3から遠ざかるほど(図の右側にいくほど)、上下面a,bの面積を広くしフィン部7の間隔が広くなるように形成して、このフィン部7の下部に空間部8を設けて凝縮器2を構成したものである。
【0022】
このとき、空間部8の高さAは、フィン部7の高さhの1/5の大きさからフィン部7の高さhまでの大きさになるようにしてある。その他の、構成、作用は実施の形態1で示した場合と同様なので、説明を省略する。
なお、上記の説明ではプロペラファン3が図の左側に位置した場合について示したが、図の右側又は中央部近傍に位置した場合も同様に、プロペラファン3に近付くほどフィン部7の上下面a,bの面積を狭くし間隔が狭くなるように形成すればよい。
【0023】
実施の形態5によれば、フィン部7の上下面a,bの面積と間隔を風路圧損に合わせて調整したので、フィン部7内を通過する空気量が各フィン部7間で均一になり、凝縮器2全体の効率が上昇する。
【0024】
実施の形態6
図9は図1の冷凍冷蔵庫を図2のB−B方向に切断した縦断面図である。実施の形態1では空間部8の上部にフィン部7を設けて凝縮器2を構成したが、実施の形態6では、フィン部7に切り起こしを設けたものである。
【0025】
11,12は凝縮器2のフィン部7の上下面a,bに設けた切り起こしで、フィン部7の上面aの下側(空間部8側)と下面bの上下両側(空間部8側及びその反対側)に設けたものである。その他の、構成、作用は実施の形態1で示した場合と同様なので、説明を省略する。
実施の形態6によれば、凝縮器2のフィン部7の上下面a,bに切り起こし11,12を設けたので、空気の流れが乱されて空気とフィン部7の伝熱面によって形成される温度境界層が破壊され、伝熱が促進され凝縮器2全体の熱交換量が増大する。
【0026】
実施の形態7
図10は図1の冷凍冷蔵庫をA−A方向に切断した断面図である。実施の形態7では、実施の形態1で示した圧縮機4に高圧シェルタイプの圧縮機4aを用いたものである。
4aは高圧シェルタイプの圧縮機で、密閉容器内に、駆動源とこれによって駆動される圧縮機構部、冷媒を吸い込む吸入管、及び圧縮機構部によって圧縮された冷媒を吐出する吐出管を有しており、この密閉容器内が吐出圧力に保持されている。その他の、構成、作用は実施の形態1で示した場合と同様なので、説明を省略する。
【0027】
実施の形態7によれば、凝縮器2における空気流量が増加し流出温度が低下するので、空気流によって圧縮機4aを効率よく冷却することができる。
【0028】
実施の形態8
図11は図1の冷凍冷蔵庫をA−A方向に切断した断面図である。実施の形態1では冷却用のファンとしてプロペラファン3を用いたが、実施の形態8ではプロペラファンの代わりに多翼ファン3aを用いたものである。その他の、構成、作用は実施の形態1で示した場合と同様なので、説明を省略する。
実施の形態8によれば、凝縮器2の伝熱が促進されて凝縮器2全体の熱交換量が増大する。
【0029】
実施の形態9
図12は図1の冷凍冷蔵庫をA−A方向に切断した断面図である。実施の形態1では冷却用のファンとしてプロペラファン3を圧縮機4の横の上流側に設けたが、実施の形態9では冷却用のファンとしてクロスフローファンを用いると共に、その取り付け位置を変えて隔壁5を取り外したものである。
3bは凝縮器2と圧縮機4の間に配設されたクロスフローファンで、凝縮器2のフィン部7の配向とほぼ直角になるように配設され、凝縮器2から出てきた空気流を圧縮機4の正面から背面方向に流すようにしてある。
なお、13a,13bは圧縮機4の両側後方の本体底部1に設けた空気流出口である。
【0030】
上記のように構成した実施の形態9の作用を説明する。空気は凝縮器2の正面からイ方向に入り込み、フィン部7の冷媒と熱交換を行なって凝縮器2の背面からそのままクロスフローファン3bのあるト方向に流れ、圧縮機4を冷却して空気流出口13a,13bからチ方向に流出する。その他の、構成、作用は実施の形態1で示した場合と同様なので、説明を省略する。
【0031】
なお、上記の説明では、凝縮器2と圧縮機4の間にクロスフローファン3bを設けたが、この位置の中央部近傍にプロペラファン3又は多翼ファン3aを設けて、凝縮器2の正面から入った空気流をこれらのファン3,3aを介してそのまま後方の圧縮機4に当てるようにしてもよい。
実施の形態9によれば、凝縮器2の全ての部分に渡って空気の圧力損失が生じないので、空気の流れが良好になり伝熱が促進されて凝縮器2全体の熱交換量が増大し、圧縮機4の放熱性能も向上する。
【0032】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a refrigerator, and more particularly, to a refrigerator having an increased heat exchange amount and improved performance.
[0002]
[Prior art]
FIG. 13 is a longitudinal sectional view showing an example of a lower portion of a conventional refrigerator-freezer. As shown in the figure, the condenser 2 is formed by a fin portion 7 (height h) that penetrates and supports the heat transfer tube 9 and a space portion 8 (height A) adjacent below the fin portion 7. Constitutes an air path. At this time, the height A of the space 8 is, for example, about 1/5 of the height h of the fin 7.
Then, the air passes through the air path including the fin portion 7 and the space portion 8 and exchanges heat with the refrigerant in the condenser 2.
[0003]
[Problems to be solved by the invention]
According to the condenser 2 of the refrigerator-freezer configured as described above, the portion through which the air can pass is only about 1/5 of the height of the fin portion 7, so that the pressure loss of the air is large and the air flow rate is reduced.
