Also, the air (indicated by the arrow) introduced from the lower suction grille 13 a of the housing 10 is sucked into the second heat exchanger 20 from the lower suction port portion 13. The air heat-exchanged by the first heat exchanger 19 or the second heat exchanger 20 is blown out obliquely downward (in the direction of the arrow) from the outlet 14 by the cross flow fan 15 through the air passage 18. At this time, the condensed water generated in the first heat exchanger 19 and the second heat exchanger 20 flows down to the respective water receiving trays 21 (see, for example, Patent Document 1).

　ファン６には、貫流ファン（クロスフローファン）が適している。ファン６は、左右両端のいずれかの回転軸に、モータを連結している（図示せず）。また、吸込口２とファン６との間、又は吸込口２と熱交換器５との間には、フィルタ４が配置されている。 For the fan 6, a cross flow fan (cross flow fan) is suitable. The fan 6 connects a motor to one of the left and right end rotation shafts (not shown). Also, a filter 4 is disposed between the suction port 2 and the fan 6 or between the suction port 2 and the heat exchanger 5.
　ファン６の下流から吹出口３の上流に至る通風路７は、ファン６の下流に配置されて空気の流れを案内し、通風路７の背面側を形成する略円弧形状のリアガイダ７ａと、このリアガイダ７ａに対向して配置されたスタビライザ７ｂと、本体１の両側壁（図示せず）とで形成されている。なお、リアガイダ７ａの上流側上端部７ｗは、ファン６と背面側熱交換部５ｂとの間に位置し、リアガイダ７ａの一部は、ファン６と背面側熱交換部５ｂとの間に位置している。 An air passage 7 extending from the downstream side of the fan 6 to the upstream side of the air outlet 3 is disposed downstream of the fan 6 to guide the flow of air and forms a rear guider 7a having a substantially arc shape forming the back side of the air passage 7. It is formed of a stabilizer 7 b disposed to face the rear guider 7 a and both side walls (not shown) of the main body 1. The upstream upper end 7w of the rear guider 7a is located between the fan 6 and the rear side heat exchange unit 5b, and a part of the rear guider 7a is located between the fan 6 and the rear side heat exchange unit 5b. ing.
　吹出口３には、上下風向変更羽根８と左右風向変更羽根９とを設けている。左右風向変更羽根９は上下風向変更羽根８より上流側に配置している。上下風向変更羽根８は、吹出口３を開閉し、空気の吹き出しを上下方向に変更する。左右風向変更羽根９は、空気の吹き出しを左右方向に変更する。 The air outlet 3 is provided with an up and down wind direction changing blade 8 and a left and right air direction changing blade 9.

　すなわち、空気調和機の暖房運転時や冷房運転時や除湿運転時等の室内機の空調運転時においては、ファン６の駆動により、吸込口２から吸い込まれた空気が、熱交換器５を流れる冷媒と熱交換される。室内機の空調運転時には、図１に示す上下風向変更羽根８が吹出口３を覆っている状態から、図２に示す吹出口３を開口させる状態へと回動し、熱交換器５を流れる冷媒と熱交換した後の空気が、吹出口３から吹き出す。 That is, during the heating operation of the air conditioner, the air conditioning operation of the indoor unit during the cooling operation, the dehumidifying operation, etc., the air sucked from the suction port 2 flows through the heat exchanger 5 by the drive of the fan 6. Heat exchange with the refrigerant. During the air conditioning operation of the indoor unit, the air flow direction changing blade 8 shown in FIG. 1 rotates from the state covering the air outlet 3 to the state where the air outlet 3 shown in FIG. Air after heat exchange with the refrigerant is blown out from the blowout port 3.
　さらに、本発明の第１の実施の形態における空気調和機の室内機は、少なくとも背面側熱交換部５ｂのリアガイダ７ａに対向する下流面５ｂｘには形状変化部５ｗを有し、形状変化部５ｗを、リアガイダ７ａの上流側上端部７ｗより背面側に位置させている。背面側熱交換部５ｂは、形状変化部５ｗより下部に位置する下流面５ｂｘを、ファン６に近づく方向に湾曲または屈曲する曲面形状としている。また、下流面５ｂｘに対向する上流面５ｂｙについても、ファン６に近づく方向に湾曲または屈曲する曲面形状としている。 Furthermore, the indoor unit of the air conditioner according to the first embodiment of the present invention has a shape changing portion 5w at least on the downstream surface 5bx of the rear heat exchange portion 5b facing the rear guider 7a, and the shape changing portion 5w Is positioned on the rear side of the upstream upper end 7w of the rear guider 7a. The rear surface side heat exchange unit 5 b has a curved surface shape in which the downstream surface 5 bx located below the shape change unit 5 w is curved or bent in a direction approaching the fan 6. Further, the upstream surface 5by that faces the downstream surface 5bx also has a curved surface shape that curves or bends in a direction approaching the fan 6.
　そして、背面側熱交換部５ｂは、少なくとも最も背面側に位置する部位５ｂｚの厚みを、形状変化部５ｗより上方側の部位の厚みよりも薄く形成している。 And back side heat exchange part 5b forms thickness of part 5bz which is located in the back most side at least thinner than thickness of a part above the shape change part 5w.
　すなわち、図２に示すように、背面側熱交換部５ｂは、形状変化部５ｗより上部では所定の厚みＴｈにて形成され、形状変化部５ｗより下部では所定の厚みＴｈより薄い厚みＴｍにて形成され、最下端に位置する部位５ｂｚでは厚みＴｍよりも更に薄い厚みＴｌにて形成されている。このように、背面側熱交換部５ｂの形状変化部５ｗから下部側の部位の厚みは、徐々に薄くなるように形成されている。すなわち、背面側熱交換部５ｂの形状変化部５ｗより上方側の厚みをＴｈ、背面側熱交換部５ｂの形状変化部５ｗより下方側、かつ、最も背面側に位置する部位の厚みをＴｍ、背面側熱交換部５ｂの形状変化部５ｗより下方側、かつ、最下端部の厚みをＴｌとすると、Ｔｌ＜Ｔｍ＜Ｔｈの関係にある。 That is, as shown in FIG. 2, the back side heat exchange portion 5b is formed with a predetermined thickness Th above the shape change portion 5w, and with a thickness Tm thinner than the predetermined thickness Th below the shape change portion 5w. The portion 5bz which is formed and located at the lowermost end is formed to have a thickness T1 thinner than the thickness Tm. Thus, the thickness of the portion on the lower side from the shape change portion 5w of the back side heat exchange portion 5b is formed to be gradually thinner. That is, the thickness on the upper side of the shape-changing portion 5w of the back side heat exchange portion 5b is Th, and the thickness of the portion located on the lower side of the shape-changing portion 5w of the back side heat exchange portion 5b and most back side is Tm, Assuming that the thickness of the lowermost end portion of the back side heat exchange portion 5b below the shape change portion 5w and the lower end portion is Tl, there is a relation of Tl <Tm <Th.
　これにより、背面側熱交換部５ｂ及びそれを搭載した室内機の本体１の横幅Ｂを狭くすることができ、設置性や美観性に優れた空気調和機の室内機を提供できる。 Thereby, the width B of the back side heat exchange part 5b and the main unit 1 of the indoor unit on which the heat exchange part 5b is mounted can be narrowed, and the indoor unit of the air conditioner excellent in the installation and the aesthetics can be provided.
　また、略円弧形状のリアガイダ７ａの背面側と背面側熱交換部５ｂとの間の空間が、リアガイダ７ａの上流側上端部７ｗに向かって、徐々に拡大することで、円滑な流れ場が形成されて送風性能が向上し、省エネ、低騒音化を実現した空気調和機の室内機を提供できる。 A smooth flow field is formed by the space between the back side of the substantially arc-shaped rear guider 7a and the back side heat exchange unit 5b gradually expanding toward the upstream upper end 7w of the rear guider 7a. Thus, it is possible to provide an indoor unit of an air conditioner in which the air blowing performance is improved and energy saving and noise reduction are realized.
　さらに、背面側熱交換部５ｂの厚みを薄くした部位の通風抵抗を減少させて、空気を流れ易くできるため、背面側熱交換部５ｂの熱交換能力を向上させることができる。 Furthermore, the air flow resistance can be reduced by reducing the ventilation resistance at the portion where the thickness of the back side heat exchange part 5b is reduced, and thus the heat exchange capacity of the back side heat exchange part 5b can be improved.
　また、図１、図２に示すように、前面側熱交換部５ａと背面側熱交換部５ｂとは別部品であり、前面側熱交換部５ａと背面側熱交換部５ｂとは、天面部にて接合されている。その結果、前面側熱交換部５ａと背面側熱交換部５ｂとは、天面部にて連続している形状となっている。 Further, as shown in FIGS. 1 and 2, the front side heat exchange portion 5a and the rear side heat exchange portion 5b are separate parts, and the front side heat exchange portion 5a and the rear side heat exchange portion 5b are a top surface portion It is joined at As a result, the front side heat exchange part 5a and the back side heat exchange part 5b are shaped so as to be continuous at the top face part.
　これにより、吸込口２から吸い込まれた空気が、熱交換器５に対して略均一に流入されるため、吸込口２から吸い込まれた空気の熱交換器５における熱交換器効率が向上する。 As a result, the air sucked in from the suction port 2 flows substantially uniformly into the heat exchanger 5, so the heat exchanger efficiency of the heat exchanger 5 for the air sucked in from the suction port 2 is improved.
　また、吸込口２から吸い込まれた空気は、ファン６に対しても、略均一に流入されるため、吹出口３から吹き出される空気の風量をＱ、ファン６を駆動させるモータ（図示せず）への入力をＷとしたとき、Ｑ／Ｗであるファン効率の向上するため、室内機の省エネも実現できる。 In addition, since the air sucked from the suction port 2 flows substantially uniformly into the fan 6 as well, the amount of air blown out from the blowout port 3 is Q, and a motor (not shown) for driving the fan 6 When the input to W) is W, since the fan efficiency which is Q / W is improved, energy saving of the indoor unit can also be realized.
　また、図１、図２に示すように、前面側熱交換部５ａの上流面５ａｙ、背面側熱交換部５ｂの上流面５ｂｙには、さらに別の熱交換器である前面側副熱交換部５ｃ、背面側副熱交換部５ｄがそれぞれ配置されている。 Further, as shown in FIG. 1 and FIG. 2, on the upstream surface 5ay of the front side heat exchange unit 5a and on the upstream surface 5by of the rear side heat exchange unit 5b, another heat exchanger, front side secondary heat exchange unit 5c, the back side sub heat exchange part 5d is arrange | positioned, respectively.
　これにより、暖房運転、冷房運転、除湿運転等の室内機の空調運転時の高能力化を実現できる。 As a result, it is possible to realize high performance during air conditioning operation of the indoor unit such as heating operation, cooling operation, and dehumidifying operation.
