Description
図1は、本実施の形態に係る室外機100を備えた空気調和装置200の模式図である。図1(a)は、空気調和装置200の冷媒回路構成の一例を示し、図1(b)では、室外機100と室内機150とが冷媒配管Pで接続されている様子を示している。なお、本実施の形態では、冷凍サイクル装置が空気調和装置200である場合の例を説明する。
空気調和装置200は、室内機150と室外機100とを有し、これらが冷媒配管Pで接続されて構成されている。室内機150は、冷房運転時に蒸発器として機能し、暖房運転時に凝縮器として機能する室内熱交換器151などを有している。そして、室外機100で生成された冷熱あるいは温熱は、冷媒配管Pを介して室内機150に配送されるようになっている。
室内機150は、たとえば室内などのように空調対象空間に冷房用空気、又は暖房用空気を供給できる位置に配置され、空調対象空間に冷房用空気、又は暖房用空気を供給するものである。室内機150は、空気と冷媒とを熱交換する室内熱交換器151、及び室内熱交換器151に空気を供給する送風機152が搭載されている。
図2Aは、本実施の形態に係る室外機100の斜視図である。図2Bは、本実施の形態に係る室外機100を分解した状態の斜視図である。図2Cは、本実施の形態に係る室外機100の水平断面図である。図2Dは、図2Cに示す領域Bの拡大図である。
室外機100は、冷房運転時に凝縮器として機能し、暖房運転時に蒸発器として機能する室外熱交換器2などを有しているものである。以下の説明では、前面パネル1Bを室外機の前面(正面)と規定し、正面に向かって第1の側面パネル1CCが配置されている側を左側と規定し、正面に向かって第2の側面パネル1Cが配置されている側を右側と規定している。
また、室外機100は、室外機100内の空間を左側と右側に区画する仕切板5、冷媒を圧縮して吐出する圧縮機4、水平断面形状がL字状の室外熱交換器2、室外熱交換器2に外気を供給する送風機3、及び、送風機3を保持するモーターサポート3Aなどが搭載されている。その他に、室外機100には、四方弁8、及び圧縮機4の回転数を制御する制御装置などが設けられた電気品箱6も搭載されている。
さらに、室外機100は、周面パネルの内側に位置するように底面パネル1Eの角部Cに配置され、底面パネル1Eに立設する固定パネル1Fと、固定パネル1Fに固定され、冷媒配管Pが接続されるバルブ7と、バルブ7を覆うように取り付けられるカバー1Dとを備えている。
天面パネル1Aは、室外機100の上面を構成するものである。天面パネル1Aは、室外熱交換器2の上部を覆うように、周面パネルの上端部に設けられたものである。天面パネル1Aは、前側端部及び左側端部が、前面パネル1B及び第1の側面パネル1CCに接触して支持されて設けられ、右側端部が第2の側面パネル1Cに接触して支持されて設けられている。天面パネル1Aは、たとえば金属板などから構成される。
前面パネル1Bは、室外機100の前面の一部を構成するものである。前面パネル1Bは、左側の側端部に第1の側面パネル1CCが設けられ、右側の側端部にカバー1Dが設けられている。また、前面パネル1Bは、右側の側端部にカバー1Dが付設される。なお、本実施の形態において、第1の側面パネル1CCと前面パネル1Bとは連結して一体的に構成されている。
前面パネル1Bは、下端部が底面パネル1Eの周縁部1E1上に設けられており、また、上端部に天面パネル1Aが設けられている。また、前面パネル1Bのうち前面構成部分の右側端部は、第2の側面パネル1Cの前側の側端部に沿うように設けられている。さらに、前面パネル1Bには、たとえば外気吸込口となる円形の開口部1B1が形成されている。なお、ファングリル1B2は、開口部1B1の形成位置に対向するように設けられている。前面パネル1Bは、たとえば樹脂などで構成される。
第2の側面パネル1Cは、室外機100の後面の一部及び右側面を構成するものである。この第2の側面パネル1Cは、水平断面形状が略L字であって底面パネル1Eに鉛直に立設され、圧縮機4の側方及び後側に配置されているものである。第2の側面パネル1Cは、前側端部がカバー1Dの側端部に沿うように設けられ、上端部が天面パネル1Aと接触して設けられ、下端部が底面パネル1Eと接触して設けられている。第2の側面パネル1Cは、たとえばABS樹脂などで構成される。
ファングリル1B2は、室外機100の前面の一部を構成し、ユーザーなどが、送風機3でケガをすることなどを防止するのに利用されるものである。このファングリル1B2は、たとえば縦桟と横桟からなる格子状部材である。
底面パネル1Eは、室外機100の底面の一部を構成するものである。底面パネル1Eは、圧縮機4及び室外熱交換器2などの下側に配置され、圧縮機4及び室外熱交換器2を支持する矩形状部材である。底面パネル1Eの周縁には、鉛直に立設する周縁部1E1が形成されている。すなわち、周縁部1E1は、底面パネル1Eの周縁部に形成されたフランジ状の部分である。底面パネル1Eの上側には、室外熱交換器2、圧縮機4及び仕切板5などが設けられている。底面パネル1Eは、たとえば金属板などから構成される。また、底面パネル1Eの下面側には、室外機100を載置するのに利用される脚部1E2が設けられている。
仕切板5は、圧縮機4及びバルブ7が配置される側と、室外熱交換器2及び送風機3が配置される側とを仕切るように配置されている。すなわち、仕切板5は、圧縮機4が設けられる機械室R1と、室外熱交換器2、送風機3、及びモーターサポート3Aなどが設けられる送風機室R2とを区画するものである。仕切板5は、たとえば、底面パネル1E上に配置される。そして、仕切板5は、前端部が前面パネル1Bに配置され、後端部が室外熱交換器2の端部に固定される。
圧縮機4は、冷媒を吸入し、その冷媒を圧縮して高温・高圧の状態にして吐出するものである。圧縮機4は、冷媒の流れを切り替えて冷房運転及び暖房運転を切り替える四方弁8に配管を介して接続されている。圧縮機4の周囲には、仕切板5、前面パネル1B、及び固定パネル1Fなどが配置されている。なお、圧縮機4の上部には、各種制御などに利用される電気品箱6が設けられている。なお、圧縮機4は、底面パネル1E上に直接載置されている必要はなく、底面パネル1Eに設けた設置台の上に載置されていてもよい。
室外熱交換器2は、送風機3によって室外機100に取り込まれる空気と冷媒との間で熱交換を行わせ、冷房運転時に冷媒を凝縮液化させ、暖房運転時に冷媒を蒸発ガス化させるものである。室外熱交換器2は、たとえば、底面パネル1E上に設けられている。なお、室外熱交換器2は、底面パネル1E上に直接載置されている必要はなく、底面パネル1Eに設けた設置台の上に載置されていてもよい。室外熱交換器2の上部には、モーターサポート3Aが掛けられるようにして設けられている。室外熱交換器2は、たとえば伝熱管を流れる冷媒とフィンを通過する空気との間で熱交換ができるようなフィンアンドチューブ熱交換器で構成される。
室外熱交換器2は、第1の側面パネル1CCから第2の側面パネル1Cに向かう方向に平行に延びる第1の熱交換部2Aと、曲げられた第2の熱交換部2Bと、第1の側面パネル1CCに対向するように設けられた第3の熱交換部2Cとを含むものである。第1の熱交換部2Aと第2の熱交換部2Bとが接続されており、第2の熱交換部2Bと第3の熱交換部2Cとが接続されている。室外熱交換器2の第2の側面パネル1C側の端部には、たとえば、各種配管及び伝熱管に冷媒を分配するヘッダーなどの冷媒流通部材20が配置されている。すなわち、冷媒流通部材20は、第1の熱交換部2Aの端部側に設けられている。なお、第3の熱交換部2Cには、伝熱管が半円状に曲げられたヘアピン2C1が設けられている。
固定パネル1Fは、圧縮機4が配置される側の空間(機械室R1)と、バルブ7が配置される側の空間とを仕切るように構成されているものである。固定パネル1Fは、底面パネル1Eから天面パネル1Aにかけて上下方向に延びるように設けられた平板状部材である。なお、カバー1D及び第2の側面パネル1Cも、底面パネル1Eから天面パネル1Aにかけて上下方向に延びるように設けられている。固定パネル1Fの一方(前側)の側端部は前面パネル1Bの内側面に対向するように位置し、固定パネル1Fの他方(後側)の側端部は第2の側面パネル1Cの前側端部に沿うように設けられている。固定パネル1Fは、前面パネル1Bとの間に鋭角が形成されるように設けられている。
バルブ7は、固定パネル1Fに取り付けられているものである。バルブ7は、細管用バルブ7A及び太管用バルブ7Bから構成されている。バルブ7には、冷媒配管Pが接続されている。バルブ7は、固定パネル1Fの外側面と底面パネル1Eの上面とカバー1Dの内側面との間に形成される閉空間SPに配置されている。このため、仮に、室外機100の筐体の内外を接続する冷媒配管Pの外側に巻かれる断熱カバーに引火しても、炎が機械室R1内へ延焼してしまうことを防ぐことができる。つまり、炎が圧縮機4及び室外熱交換器2などに及ぶことを回避することができるようになっている。
カバー1Dは、底面パネル1Eの周縁部1E1上に配置され、バルブ7を覆うように固定パネル1Fの対向位置に着脱自在に設けられたものである。カバー1Dは、底面パネル1Eの角部Cに対応する位置に取り付けられるものである。カバー1Dは、室外機100の筐体のうちの前面の一部及び右側面の一部を構成する。カバー1Dは、水平断面視形状が、L字状となっている。カバー1Dは、上下方向に延びるように設けられている。カバー1Dは、前面パネル1Bに平行に設けられる前面部1D1と、前面部1D1に直交する側面部1D2と、バルブ7に接続される冷媒配管Pを引き出すのに利用される引出部1D3とを含むものである。カバー1Dは、前面部1D1、側面部1D2及び引出部1D3が一体的に形成されたものである。カバー1Dは、たとえば、樹脂などで構成してもよいし、金属板などで構成してもよい。
側面部1D2は、第2の側面パネル1Cの外表面に沿うように設けられた平板状部材である。側面部1D2は、底面パネル1Eから天面パネル1Aまで延びるように形成された平板状部材である。側面部1D2の後側の側端部には、バルブ7の高さ位置に、引出部1D3が形成されている。
引出部1D3は、側面部1D2よりも右側に突出するように形成されているものである。したがって、カバー1Dの側面は、引出部1D3の形成部分が段差状になっている。仮に、カバー1Dに引出部1D3が形成されていないと、冷媒配管Pの引出は容易であるが、雨水などが室外機100の筐体内に侵入してしまう。しかし、カバー1Dには、側面部1D2よりも突出している引出部1D3が形成されているため、冷媒配管Pとの干渉を回避しながらも、雨水などが室外機100の筐体内に侵入することを抑制することができるようになっている。
本実施の形態に係る室外機100は、周面パネル(前面パネル1B及び第2の側面パネル1C)の内側に位置するように底面パネル1Eの角部Cに配置され、底面パネル1Eに立設する固定パネル1Fと、固定パネル1Fに固定され、冷媒配管Pが接続されるバルブ7とを備えたものである。このため、バルブ7が室外機100の底面パネル1Eの周縁部1E1よりも内側に位置することになる。つまり、室外機100では、従来の室外機のようにバルブが室外機の筐体の外側から飛び出してしまうようなことを回避することができる。したがって、本実施の形態に係る室外機100は、サイズを小さくすることができる。
図3Aは、本実施の形態に係る室外機100の変形例1の斜視図である。図3Bは、図3Aに示す変形例1に係る室外機100を分解した状態の斜視図である。図3Cは、変形例2に係る室外機100の水平断面図である。図3Dは、変形例2に係る室外機100のカバー1Dを外した状態における説明図である。なお、図3D(a)は、変形例1に係る室外機100の正面図であり、図3D(b)は、変形例1に係る室外機100の右側面図であり、図3D(c)は、変形例1に係る室外機100の斜視図である。変形例1では、本実施の形態とは異なり、固定パネル1Fの高さが天面パネル1Aまで至っていない。
変形例1に係る室外機100は、本実施の形態に係る室外機100と同様の効果を有することに加えて、機械室R1の容積を大きくすることができ、室外機100内の限られたスペースを有効活用しやすいという効果がある。
図4Aは、本実施の形態に係る室外機100の変形例2の斜視図である。図4Bは、図4Aに示す変形例2に係る室外機100を分解した状態の斜視図である。図4Cは、変形例2に係る室外機100の水平断面図である。図4Dは、変形例2に係る室外機100のカバー1Dを外した状態における説明図である。図4Eは、変形例2に係る室外機100の説明図であって、カバー1Dを取り付けている状態における説明図である。なお、図4D(a)は、変形例2に係る室外機100の正面図であり、図4D(b)は、変形例2に係る室外機100の右側面図であり、図4D(c)は、変形例2に係る室外機100の上面視図である。変形例2では、室外熱交換器2の端部に第1の突出部Jが形成されており、室外熱交換器2の横幅を大きくしながらも、室外機100の大型化を抑制することができるものとなっている。
変形例2に係る室外機100は、本実施の形態に係る室外機100と同様の効果を有することに加えて、次の効果を有する。すなわち、変形例2に係る室外機100では、室外熱交換器2の端部に第1の突出部Jが形成されており、室外熱交換器2の横幅を大きくしながらも、室外機100の大型化を抑制することができるものとなっている。
また、変形例2に係る室外機100では、第2の側面パネル1Cにもテーパー面J1に平行なテーパー面が形成されているため、冷媒配管Pを側面に沿わせて配置することができる。このため、冷媒配管Pが邪魔になることを回避するとともに、冷媒配管Pが破損などをすることを抑制することができる。
図5Aは、本実施の形態に係る室外機100の変形例3の正面図である。図5Bは、変形例3に係る室外機100の水平断面図である。図5Cは、図5Bに示す領域Bの拡大図である。図5Dは、変形例3に係る室外機100のカバー1Dを外した状態における説明図である。なお、図5D(a)は、変形例3に係る室外機100の斜視図であり、図5D(b)は、変形例3に係る室外機100の上面視図である。変形例3では、バルブ7の配置位置に第2の突出部Zを形成して、機械室R1の容積を拡大している。
変形例3に係る室外機100は、本実施の形態に係る室外機100と同様の効果を有することに加えて、次の効果を有する。すなわち、変形例3に係る室外機100では、第2の突出部Zの上側にバルブ7が配置されるようにしたので、その分、機械室R1の容積を増大させることができ、室外機100内の限られたスペースを有効活用することができる。
また、変形例3に係る室外機100は、第2の突出部Zの前端が、脚部1E2の前端よりも突出しないように設けられているので、室外機100の輸送効率を悪化させずに、機械室を拡大することができるという効果がある。
さらに、変形例3に係る室外機100は、底面パネル1Eに第2の突出部Zを形成し、その第2の突出部Zの形成位置にバルブ7が設けられた固定パネル1Fが配置されている。室外機100を設置したときにおいて、第2の突出部Zの形成位置は、室外機100の前面部にあたり、風路を形成するデッドスペースとなっている。このため、第2の突出部Zを形成した室外機100を設置しても、室外機100が設置されたスペース(ベランダなど)の利用がしにくくなることを回避することができる。
