ケーシング(21)は、下面が開口する直方体型の箱状に形成されている。ケーシング(21)の内面には、断熱材(図示を省略)が設けられている。また、ケーシング(21)は、室内ファン(31)と室内熱交換器(32)とドレンパン(33)とベルマウス(34)とを収容する。
室内ファン(31)は、ケーシング(21)の内部中央に配置される。この例では、室内ファン(31)は、下方から吸い込んだ空気を側方から径方向外方へ吹き出すように構成されている。具体的には、室内ファン(31)は、ファンモータ(31a)と羽根車(31b)とを有している。ファンモータ(31a)は、ケーシング(21)の天板に固定され、羽根車(31b)は、ファンモータ(31a)の回転軸に連結されている。
室内熱交換器(32)は、室内ファン(31)の周囲を囲うように配置され、冷媒と室内ファン(31)によって搬送された空気とを熱交換させるように構成されている。例えば、室内熱交換器(32)は、クロスフィン式のフィン・アンド・チューブ型熱交換器によって構成されている。また、室内ユニット(10)に設けられる室内熱交換器(32)と、室外ユニット(図示を省略)に設けられる圧縮機と室外熱交換器と膨張弁とが配管接続されて、冷媒回路が構成されている。この冷媒回路では、冷媒が可逆に循環して蒸気圧縮式冷凍サイクルが行われる。そして、室内熱交換器(32)は、冷房運転では蒸発器として機能して空気を冷却し、暖房運転では放熱器(凝縮器)として機能して空気を加熱する。
ドレンパン(33)は、上下に扁平な立方体状に形成され、室内熱交換器(32)の下側に配置される。また、ドレンパン(33)には、1つの空気導入口(33a)と、複数(この例では、4つ)の空気導出口(33b)と、ドレン溝(33c)が形成されている。空気導入口(33a)は、ドレンパン(33)の中央部に形成され、ドレンパン(33)を上下に貫通している。4つの空気導出口(33b)は、空気導入口(33a)の周囲に形成され、ドレンパン(33)を上下に貫通している。ドレン溝(33c)は、室内熱交換器(32)の下端に沿うように環状に形成され、室内熱交換器(32)において発生した凝縮水を受ける。この例では、4つの空気導出口(33b)は、平面視においてドレンパン(33)の4つの辺部にそれぞれ沿うように形成されている。また、ドレン溝(33c)は、平面視において空気導入口(33a)と4つの空気導出口(33b)との間を環状に延びている。
ベルマウス(34)は、上縁から下縁へ向かうに連れて開口面積が拡大する筒状に形成され、その上縁が室内ファン(31)の開口下端(吸込口)に挿入された状態で、ドレンパン(33)の空気導入口(33a)に収容される。
チャンバ(40)は、上下に扁平な立方体状に形成され、室内ユニット本体(20)の下側に配置される。また、チャンバ(40)には、1つの吸込連通口(40a)と、複数(この例では、4つ)の吹出連通口(40b)とが形成されている。吸込連通口(40a)は、チャンバ(40)の中央部に形成され、チャンバ(40)を上下に貫通してドレンパン(33)の空気導入口(33a)と連通している。4つの吹出連通口(40b)は、吸込連通口(40a)の周囲に形成され、チャンバ(40)を上下に貫通してドレンパン(33)の4つの空気導出口(33b)とそれぞれ連通している。この例では、4つの吹出連通口(40b)は、平面視においてチャンバ(40)の4つの辺部にそれぞれ沿うように形成されている。
化粧パネル(50)は、チャンバ(40)を挟んで室内ユニット本体(20)の下側に設けられる。また、化粧パネル(50)は、パネル本体(51)と、グリル(52)と、板部材(53)と、複数(この例では、4つ)の吊下支持部(54)と、フィルタ(55)と、複数(この例では、4つ)の風向調節羽根(56)とを有している。
パネル本体(51)は、上下に扁平な立方体状に形成されている。また、パネル本体(51)には、1つの空気吸込口(51a)と、複数(この例では、4つ)の空気吹出口(51b)とが形成されている。この例では、パネル本体(51)は、平面視において正方形状に形成されている。また、パネル本体(51)は、その下面の中央部分(具体的には、4つの空気吹出口(51b)よりも内側に位置する部分)が平坦面状に形成され、その下面の外周縁部分が外周へ向かうに連れて緩やかに上方に傾斜する傾斜面状に形成されている。
グリル(52)は、空気の流れを妨げる板状(具体的には、無孔の板状)に形成され、空気吸込口(51a)の下端部に設けられる。そして、グリル(52)は、平面視においてその外周縁と空気吸込口(51a)の開口縁との間に吸込開口(60)が形成されるように、空気吸込口(51a)の中央部を覆っている。
板部材(53)は、空気吸込口(51a)の内周に沿って延びる板状に形成され、その上縁が下縁よりも内周側に位置するように空気吸込口(51a)の内周に設けられる。そして、板部材(53)は、その上縁が空気吸込口(51a)の下端よりも上方に位置し、その下縁が平面視においてグリル(52)の外周を囲っている。
図1~図6に示すように、4つの吊下支持部(54)は、空気吸込口(51a)の内周に設けられ、グリル(52)を吊り下げるとともに板部材(53)を支持する。具体的には、各吊下支持部(54)は、第1延出部(54a)と第2延出部(54b)とを有している。なお、図5は、斜め上方から見た吊下支持部(54)を拡大して示した部分斜視図である。図6は、吊下支持部(54)の第1延出部(54a)の延出方向に沿う化粧パネル(50)の縦断面のうち吊下支持部(54)の近傍を拡大して示した部分縦断面図であり、図4のVI-VI線における部分縦断面図に相当する。
図1~図4に示すように、フィルタ(55)は、パネル本体(51)の空気吸込口(51a)の上側に設けられ、空気吸込口(51a)を通過した空気の中の塵埃を補足するように構成されている。フィルタ(55)は、平面視において正方形型の格子枠状に形成され、パネル本体(51)の中央部の上側に取り付けられて空気吸込口(51a)を覆っている。
図1~図4に示すように、4つの風向調節羽根(56)は、パネル本体(51)の4つの空気吹出口(51b)の下端部にそれぞれ設けられ、空気吹出口(51b)を流れる空気の流れの向きを調節するように構成されている。風向調節羽根(56)は、空気吹出口(51b)の長手方向に沿って延びる板状に形成され、その長手方向の両端部に揺動軸が設けられている。そして、風向調節羽根(56)は、揺動軸を軸心として揺動可能となるように、パネル本体(51)に支持されている。
次に、図7を参照して、化粧パネル(50)の要部について詳しく説明する。なお、図7の中央部は、化粧パネル(50)の縦断面を示し、図7の上部は、上方から見た化粧パネル(50)の要部(空気吸込口(51a)の近傍)を示し、図7の下部は、下方から見た化粧パネル(50)の要部を示している。また、図7の中央部では、吊下支持部(54)とフィルタ(55)と風向調節羽根(56)の図示を省略している。
図7の下部に示すように、第1吸込開口(61)の開口面積は、第2吸込開口(62)の開口面積よりも広くなっている。なお、図7では、第1吸込開口(61)には、線間隔の狭い右上がりのハッチングが付され、第2吸込開口(62)には、線間隔の狭い左上がりのハッチングが付されている。
図7の上部に示すように、第1開口部(63)の開口面積は、第2開口部(64)の開口面積よりも広くなっている。なお、第1開口部(63)は、板部材(53)の上縁に囲まれた領域であり、第2開口部(64)は、平面視において板部材(53)の上縁と空気吸込口(51a)の内周面との間に挟まれた領域である。また、図7では、第1開口部(63)には、線間隔の広い右上がりのハッチングが付され、第2開口部(64)には、線間隔の広い左上がりのハッチングが付されている。
また、第2吸込開口(62)に対する第1吸込開口(61)の開口面積の割合は、第2開口部(64)に対する第1開口部(63)の開口面積の割合よりも大きくなっている。なお、第2吸込開口(62)に対する第1吸込開口(61)の開口面積の割合は、第2開口部(64)に対する第1開口部(63)の開口面積の割合と同等となっていてもよい。
図7の中央部に示すように、板部材(53)の下縁の高さは、空気吸込口(51a)の下端の高さと同一となっている。なお、板部材(53)の下縁の高さは、空気吸込口(51a)の下端の高さよりも高くなっていてもよい。また、この例では、図7の下部に示すように、板部材(53)の下縁は、平面視において吸込開口(60)の内周縁と外周縁との間の中心線(CL)よりも外周側に位置している。また、この例では、図7の中央部に示すように、板部材(53)の下縁の高さは、グリル(52)の下面の高さと同一となっている。なお、板部材(53)の下縁の高さは、グリル(52)の下面の高さよりも高くなっていてもよい。
図7の上部および中央部に示すように、板部材(53)の上縁は、平面視においてグリル(52)の外周縁と重なっている。なお、板部材(53)の上縁は、平面視においてグリル(52)の外周縁よりも内周側に位置していてもよい。
次に、下方から見た室内ユニット(10)の外観について説明する。図2に示すように、板部材(53)は、その上縁が下縁よりも内周側に位置するように、空気吸込口(51a)の内周に配置されている。そのため、図3に示すように、天井(CE)に設けられた室内ユニット(10)を下方から見た場合、吸込開口(60)から室内ユニット(10)の内部部品(この例では、フィルタ(55))が見えにくくなっている。
次に、図8を参照して、室内ユニット(10)における空気の流れについて説明する。なお、図8では、吊下支持部(54)の図示を省略している。
以上のように、板部材(53)の上縁が下縁よりも内周側に位置し、板部材(53)の上縁が空気吸込口(51a)の下端よりも上方に位置し、板部材(53)の下縁が平面視においてグリル(52)の外周を囲うように板部材(53)を設けることにより、吸込開口(60)の開口面積を確保しつつ、吸込開口(60)から室内ユニット(10)の内部部品(この例では、フィルタ(55))を見えにくくすることができる。これにより、吸込開口(60)における通風抵抗の増加を抑制しつつ化粧パネル(50)の意匠性を向上させることができる。
図9に示すように、板部材(53)の下縁から上縁へ向かうに連れて、グリル(52)の外周縁を曲率中心とする板部材(53)の曲率半径(CR)が次第に大きくなるように、板部材(53)が構成されていてもよい。なお、図9では、板部材(53)の上縁から下縁に亘って板部材(53)の曲率半径が同一である場合の板部材(53)の内周面を二点鎖線で示している。
また、図10に示すように、板部材(53)は、グリル(52)の外周縁に対して凹となるL字状に湾曲(または屈曲)するように形成されていてもよい。または、図11に示すように、板部材(53)は、空気吸込口(51a)の外周側から内周側へ向けて直線的に上方傾斜するように形成されていてもよい。
図12に示すように、グリル(52)は、その下面の高さが空気吸込口(51a)の下端の高さよりも高くなるように、空気吸込口(51a)の下端部に設けられていてもよい。この例では、グリル(52)は、その下面が平坦面状に形成され、その下面がパネル本体(51)の下面と平行となっている。
図13に示すように、4つの吊下支持部(54)は、グリル(52)の4つの辺部(この例では、4つの辺部の中央部)にそれぞれ配置されていてもよい。この例では、空気吸込口(51a)は、平面視において矩形状に形成され、グリル(52)は、平面視において矩形状に形成されている。そして、吊下支持部(54)の第1延出部(54a)は、平面視において空気吸込口(51a)の辺部からグリル(52)の辺部へ向けて延出している。吊下支持部(54)の第2延出部(54b)の下端は、グリル(52)の辺部に接続されている。このように構成した場合も、グリル(52)を吊り下げるとともに板部材(53)を支持することができる。
図14は、実施形態2による空気調和機の室内ユニット(10)の構成例を示している。実施形態2の室内ユニット(10)は、化粧パネル(50)の構造が実施形態1の室内ユニット(10)と異なっている。実施形態2の室内ユニット(10)のその他の構成は、実施形態1の室内ユニット(10)の構成と同様となっている。なお、図14は、実施形態2による室内ユニット(10)の縦断面を示した縦断面図であり、図3のII-II線における縦断面図に対応する。
図15,図16に示すように、実施形態2の化粧パネル(50)は、パネル本体(51)の空気吸込口(51a)の構造とグリル(52)の構造と板部材(53)の構造が実施形態1の化粧パネル(50)と異なっている。また、実施形態2の化粧パネル(50)では、吊下支持部(54)の代わりに、板部材(53)が第1接続部(53a)と第2接続部(53b)を有している。実施形態2の化粧パネル(50)のその他の構造は、実施形態1の化粧パネル(50)の構造と同様となっている。なお、図15は、斜め上方から見た板部材(53)の要部(第1接続部(53a)と第2接続部(53b))を拡大して示した部分斜視図である。図16は、板部材(53)の第1接続部(53a)の延出方向に沿う化粧パネル(50)の縦断面のうち吊下支持部(54)の近傍を拡大して示した部分縦断面図であり、図4のVI-VI線における部分縦断面図に対応する。
パネル本体(51)の空気吸込口(51a)は、その開口面積が上端から下端へ向かうに連れて次第に広くなるように構成されている。また、空気吸込口(51a)は、その内周面がグリル(52)の外周縁に対して凹となるように曲がっている。
グリル(52)の角部には、突起部(102)と係止鉤(103)とが設けられている。突起部(102)は、グリル(52)から上方へ向けて突出している。係止鉤(103)は、突起部(102)よりも内周側に位置している。そして、係止鉤(103)は、グリル(52)から上方へ向けて突出し、後述する係止孔(104)に引っ掛けることができるように、その先端部が内周側へ向けてL字状に屈曲している。
板部材(53)は、第1接続部(53a)と第2接続部(53b)とを有している。そして、第1接続部(53a)は、パネル本体(51)とネジ止めによって接続され、第2接続部(53b)は、グリル(52)と鉤止めおよびネジ止めによって接続されている。
第1接続部(53a)は、空気吸込口(51a)の内周部(この例では、空気吸込口(51a)の固定台部(101))へ向けて延出して空気吸込口(51a)の内周部に接続されている。この例では、第1接続部(53a)は、板面が上下を向く状態で板部材(53)の下縁部から固定台部(101)の凹部(101a)へ向けて延びる板状に形成されている。具体的には、第1接続部(53a)は、板部材(53)の下縁部から固定台部(101)の凹部(101a)へ向けて斜め上方に延出し、その先端部(上端部)が凹部(101a)の底部に沿うようにL字状に屈曲している。なお、この例では、第1接続部(53a)の先端部は、平面視において三角形状に形成され、固定台部(101)の凹部(101a)は、第1接続部(53a)の先端部の形状に対応する形状(具体的には、三角形状)に形成されている。
第2接続部(53b)は、グリル(52)へ向けて延出してグリル(52)に接続されている。この例では、第2接続部(53b)は、板面が上下を向く状態で板部材(53)の上縁部から内周側へ向けて下方に延出する板状に形成され、その先端部(下端部)がグリル(52)の上面と平行となるようにL字状に屈曲している。
以上のように構成した場合も、実施形態1と同様の効果を得ることができる。具体的には、板部材(53)を設けることにより、吸込開口(60)における通風抵抗の増加を抑制しつつ化粧パネル(50)の意匠性を向上させることができる。
なお、第2吸込開口(62)の開口幅(すなわち、板部材(53)の下縁と空気吸込口(51a)の開口縁との間隔)は、空気が第2吸込開口(62)を通過する際に風切り音が発生しないように設定されていることが好ましい。具体的には、第2吸込開口(62)の開口幅は、吸込開口(60)の開口幅(すなわち、グリル(52)の外周縁と空気吸込口(51a)の開口縁との間隔)の1/4以上に設定されていることが好ましい。
