Description

【０００１】
【発明の属する技術分野】
本発明は、床置型空気調和機に関し、特に熱交換器の構成に関するものである。
【０００２】
【従来の技術】
本願発明にかかる従来の技術について図４を用いて説明する。図４は従来の床置型空気調和機を示す縦断面図である。同図において、１は空気調和機本体で、前面下部に設けられた本体吸込口２、前面上部に設けられた本体吹出口３、本体背面を形成するリアパネル４、本体前面のフロントパネル５等で構成されている。６はリアパネル４の下部に取り付けられたケーシングで、このケーシング６の内部に一端がリアパネル４で支持されたモータ７が収納されると共に、モータ７の他端、軸の先端にはファン８が装着されている。６ａは本体吸込口２に対向するケーシング吸込口、６ｂは本体内上部に向かって開口するケーシング吹出口、９はケーシング６の上方に逆Ｖ字形（「人」字形）に構成された熱交換器である。即ち、所定の熱交換器伝熱面積を確保しつつ本体高さを低くして構成できるようにしたり、または同じ室内機筐体容積においてより多くの伝熱面積を確保すべくより多くの容量の熱交換器を配設することができるものである（特許文献１参照）。
【０００３】
【特許文献１】
中国実用新案登録ＣＮ２４４６４４２Ｙ号公報（特に図３）
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の床置型空気調和機構成では、熱交換器９を通過する空気の風速分布速度はリアパネル４側の背面熱交換器９ｂ部が速く、本体吹出口３側の前面熱交換器９ａ部では遅くなり風速分布が均一にならない。そのため熱交換器９の性能が最大限に活用されない可能性が高い。また、本体吹出口３から室内へ吹き出される空気の風速分布も均一でなくなり、風の乱れによって例えば冷房運転時に本体吹出口３に結露が生じる可能性があるという課題を有していた。
【０００５】
本発明はこのような従来の課題を解決するものであり、本体吹出口３が熱交換器９より高い場合において、熱交換器９を逆Ｖ字形に配設し、本体背面を形成するリアパネル４側の背面熱交換器９ｂの列数が本体吹出口３側の前面熱交換器９ａの列数より多くすることによって、また、本体吹出口３が熱交換器９の前面側にある場合において、熱交換器を逆Ｖ字形に配設し、本体吹出口３側の前面熱交換器９ａの列数が本体背面を形成するリアパネル４側の背面熱交換器９ｂの列数より多くすることによって、熱交換器を通過する空気の風速分布を前面側およびリアパネル側でより均一にして熱交換器の効率を高めるとともに、本体吹出口の結露を未然に防止する床置型空気調和機を提供することを目的とする。
【０００６】
【課題を解決するための手段】
請求項１の床置型空気調和機は、本体前面下部に設けられた上流側の本体吸込口から本体前面上部に設けられた下流側の本体吹出口の間に、上流側から順に送風機、熱交換器を配設した床置型空気調和機において、本体吹出口が熱交換器より高い場合において、熱交換器を逆Ｖ字形に配設し、本体背面を形成するリアパネル側の背面熱交換器の列数が本体吹出口側の前面熱交換器の列数より多くし、熱交換器を通過する空気の風速分布を熱交換器の前面及びリアパネル側でより均一になるように熱交換器を構成したことを特徴とする。
【０００７】
請求項２の床置型空気調和機は、請求項１記載のものにおいて、熱交換器の上部に本体吹出口の下面よりも下方になるように配設された補助加熱部を有するものである。
【０００８】
請求項３の床置型空気調和機は、本体前面下部に設けられた上流側の本体吸込口から本体前面上部に設けられた下流側の本体吹出口の間に、上流側から順に送風機、熱交換器を配設した床置型空気調和機において、本体吹出口が熱交換器の前面側にある場合において、熱交換器を逆Ｖ字形に配設し、本体吹出口側の前面熱交換器の列数が本体背面を形成するリアパネル側の背面熱交換器の列数より多くし、熱交換器を通過する空気の風速分布を前面及びリアパネル側でより均一になるように構成したことを特徴とする。
【０００９】
【発明の実施の形態】
以下、本発明の実施の形態について図面を参照して説明する。
【００１０】
（実施の形態１）
図１は本発明の実施の形態１による床置型空気調和機の縦断面図である。図において、符号１〜９は従来の床置型空気調和機と同一のものであり、その詳細な説明は省略する。
【００１１】
本実施の形態によれば、送風機のケーシング吹出口６ｂの上方で、本体吹出口３が熱交換器９より高い場合において、熱交換器９を逆Ｖ字形に配設し、本体背面を形成するリアパネル４側の背面熱交換器９ｂ（風速分布の高い方）の列数が本体吹出口３側の前面熱交換器９ａ（風速分布の低い方）の列数より多くしたので、熱交換器９を通過する空気の風速分布をより均一にすることができ、熱交換器９の性能を向上する効果を奏すると共に、熱交換器の風速分布をより均一にすることができ、本体吹出口の結露を防止するという効果を奏する。
【００１２】
なお、本実施の形態では風速分布の大きい側の熱交換器の列数を大きくするようにして風速分布の均一化を図っているが、その他の方法として風速分布の大きい側の熱交換器のフィンピッチを狭くしたり、熱交換器を構成するフィンの切り起こし形状をより複雑化して構成し、伝熱効率を向上させるとともに送風の抵抗となるように構成してもよい。
【００１３】
（実施の形態２）
図２は本発明の実施の形態２による床置型空気調和機の縦断面図である。
【００１４】
この実施の形態によれば、送風機のケーシング吹出口６ｂの上方で、本体吹出口３が熱交換器９の前面側にある場合において、熱交換器９を逆Ｖ字形に配設し、本体吹出口３側の前面熱交換器９ａ（風速分布の高い方）の列数が本体背面を形成するリアパネル４側の背面熱交換器９ｂ（風速分布の低い方）の列数より多くしたので、熱交換器９を通過する空気の風速分布を均一にすることができ、熱交換器９の性能を向上する効果を奏すると共に、本体吹出口の風速分布を均一にすることができ、本体吹出口の結露を防止するという効果を奏する。
【００１５】
（実施の形態３）
図３は本発明の実施の形態３による床置型空気調和機の縦断面図である。図において、符号１〜９は従来の床置型空気調和機と同一のものであり、その詳細な説明は省略する。
【００１６】
この実施の形態によれば、実施の形態１記載のものにおいて、電気ヒータ１０（補助加熱部）は、熱交換器９の上部に本体吹出口３の下面よりも下方になるように配設したので、電気ヒータ通電による加熱時の本体吹出口３での空気の温度むら少なくしてより均一な温度の空気を吹き出すことができ、暖房時に快適な室内空間が得られるという効果を奏する。また、吹出口正面から電気ヒータが見えないように構成されているため、フィンガーテスト等に係り、ユーザが誤ってヒータに触れてしまうことを防止するための保護部材などが不要であり、部品点数が減ると共に組立性がさらに向上する。
【００１７】
【発明の効果】
以上の説明から明らかなように、本願発明によれば、熱交換器を通過する空気の風速分布をより均一にすることができ、熱交換器の性能を向上すると共に、本体吹出口の風速分布を均一にすることができ、本体吹出口の結露を防止することができる。
