More specifically, the bottom surface of the second water tray 112 is positioned below the bottom surface of the first water tray 111 . The height difference between the bottom surface of the first water receiving tray 111 and the bottom surface of the second water receiving tray 112 is sufficient to allow the drain water that drips onto the first water receiving tray 111 to flow down to the second water receiving tray 112 through the communicating portion 114. .

　〔１－２　動作〕
　以上のように構成された空気調和機１００について、以下その動作、作用を説明する。 [1-2 Operation]
The operation and effects of the air conditioner 100 configured as described above will be described below.
　熱交換時に第１熱交換器１０９の表面に発生するドレン水は、第１水受皿１１１に滴下し、さらに第１水受皿１１１よりも下方に位置する第２水受皿１１２へと連通部１１４を通じて流下する。第１水受皿１１１から第２水受皿１１２へ到達したドレン水、および熱交換時に第２熱交換器１１０の表面に発生するドレン水は、第２水受皿１１２の底部に備えられた排水口１１５から筐体１０５の外へ排出される。 Drain water generated on the surface of the first heat exchanger 109 during heat exchange drips onto the first water receiving plate 111 and then flows through the communicating portion 114 to the second water receiving plate 112 located below the first water receiving plate 111 . flow down Drain water reaching the second water receiving tray 112 from the first water receiving tray 111 and drain water generated on the surface of the second heat exchanger 110 during heat exchange are discharged through a drain port 115 provided at the bottom of the second water receiving tray 112 . is discharged to the outside of the housing 105 .
　この際、第１水受皿１１１の高さ位置と第２水受皿１１２の高さ位置との間には高低差があるため、ドレン水は第１水受皿１１１及び第２水受皿１１２に滞留せずに排水口１１５に向かい、排水口１１５を通じて筐体１０５の外へ排出される。 At this time, since there is a height difference between the height position of the first water receiving tray 111 and the height position of the second water receiving tray 112, the drain water stays in the first water receiving tray 111 and the second water receiving tray 112. It goes directly to the drain port 115 and is discharged out of the housing 105 through the drain port 115 .
　〔１－３　効果〕
　以上のように、本実施の形態において、空気調和機１００は、筐体１０５と、筐体１０５の内部に水平方向に回転軸をもつクロスフローファン１０６と、舌部１０７ａを有し、舌部１０７ａがクロスフローファン１０６に近接して配置されたスタビライザ１０７と、スタビライザ１０７とともに通風路を形成するリアガイダ１０８と、クロスフローファン１０６をそれぞれ前後から挟むように筐体１０５の正面側に配置された第１熱交換器１０９及び筐体１０５の背面側に配置された第２熱交換器１１０と、を有する。空気調和機１００はさらに、第１熱交換器１０９の下方に配置された第１水受皿１１１と、第２熱交換器１１０の下方に配置された第２水受皿１１２と、第１水受皿１１１と第２水受皿１１２とを連絡する連通部１１４と、を備える。第１熱交換器１０９の形状と第２熱交換器１１０の形状とは同一である。第１熱交換器１０９及び第２熱交換器１１０は、第１熱交換器１０９の下端の高さ位置が、第２熱交換器１１０下端の高さ位置より上方に設けられている。 [1-3 Effect]
As described above, in the present embodiment, the air conditioner 100 has the housing 105, the cross-flow fan 106 having the rotation shaft in the horizontal direction inside the housing 105, and the tongue portion 107a. 107a is arranged on the front side of the housing 105 so as to sandwich the stabilizer 107 arranged close to the cross-flow fan 106, the rear guider 108 forming the ventilation path together with the stabilizer 107, and the cross-flow fan 106 from the front and back. and a first heat exchanger 109 and a second heat exchanger 110 arranged on the rear side of the housing 105 . The air conditioner 100 further includes a first water tray 111 arranged below the first heat exchanger 109, a second water tray 112 arranged below the second heat exchanger 110, and the first water tray 111. and a communicating portion 114 that communicates with the second water receiving tray 112 . The shape of the first heat exchanger 109 and the shape of the second heat exchanger 110 are the same. The first heat exchanger 109 and the second heat exchanger 110 are provided such that the height position of the lower end of the first heat exchanger 109 is higher than the height position of the lower end of the second heat exchanger 110 .
　これにより、第１水受皿１１１と第２水受皿１１２との間の高低差によってドレン水の滞留を抑制することができる。このため、第１水受皿１１１または第２水受皿１１２においてドレン水に雑菌が繁殖することが抑制される。また、ドレン水と塵埃とが混ざり合って生じるヘドロ状のスライムの発生が抑制される。従って、空気調和機１００を清潔に維持することができる。 As a result, the accumulation of drain water can be suppressed due to the height difference between the first water receiving tray 111 and the second water receiving tray 112 . Therefore, the propagation of bacteria in the drain water in the first water receiving tray 111 or the second water receiving tray 112 is suppressed. In addition, generation of sludge-like slime caused by mixing of drain water and dust is suppressed. Therefore, the air conditioner 100 can be kept clean.
　なお、上方に位置する第１水受皿１１１の壁の上端と、下方に位置する第２水受皿１１２の底部との間の高低差が、排水口１１５におけるヘッドとなり得る。従って、排水口１１５を備える第２水受皿１１２の底部にヘドロ状のスライムが発生した場合にも、ドレン水によってヘドロ状のスライムを押し流すのに必要なヘッドが確保されるため、ドレン水の排水性を向上することができる。 The height difference between the upper end of the wall of the first water tray 111 positioned above and the bottom of the second water tray 112 positioned below can be the head of the drain port 115 . Therefore, even if sludge-like slime occurs at the bottom of the second water receiving tray 112 having the drain port 115, the head necessary for washing away the sludge-like slime is secured by the drain water. can improve sexuality.
　なお、空気調和機の熱交換器については、前述のように、第１熱交換器１０９及び第２熱交換器１１０の少なくともいずれか一方が、プレートフィン積層型熱交換器であってもよい。プレートフィン積層型熱交換器の場合においては、第１熱交換器１０９の傾斜と第２熱交換器１１０の傾斜とが異なると、冷媒の分流性能に影響を与える可能性がある。本実施の形態のように、第１熱交換器１０９の下端と第２熱交換器１１０の下端との間に高低差を設けることにより、第１熱交換器１０９の傾斜と第２熱交換器１１０との傾斜の違いを解消できるため、プレートフィン積層型熱交換器が用いられた場合において、熱交換器での冷媒の分流の制御性を安定させることができる。 As for the heat exchanger of the air conditioner, as described above, at least one of the first heat exchanger 109 and the second heat exchanger 110 may be a plate fin laminated heat exchanger. In the case of the plate fin laminated heat exchanger, if the inclination of the first heat exchanger 109 and the inclination of the second heat exchanger 110 are different, there is a possibility that the refrigerant flow division performance is affected. As in the present embodiment, by providing a height difference between the lower end of the first heat exchanger 109 and the lower end of the second heat exchanger 110, the inclination of the first heat exchanger 109 and the second heat exchanger Since the difference in inclination with respect to 110 can be eliminated, the controllability of the refrigerant branch flow in the heat exchanger can be stabilized when the plate-fin laminated heat exchanger is used.

The first heat exchanger 109 and the second heat exchanger 110 are substantially symmetrical with respect to a symmetrical reference plane 113 parallel to the rotation center axis of the cross flow fan 106, but the lower end of the first heat exchanger 109 is located at the second It is arranged so as to be positioned below the lower end of heat exchanger 110 . The height difference between the first heat exchanger 109 and the second heat exchanger 110 is such that the drain water dripping onto the second water receiving pan 112 arranged below the second heat exchanger 110 passes through the communicating portion 114 to the first heat exchanger. It suffices if it flows down to the first water receiving tray 111 arranged below the exchanger 109 . Desirably, the height difference is such that, even when sludge-like slime occurs at the bottom of the first water receiving tray 111 having the drain port 115, the drain water pushes the sludge-like slime away from the drain port 115. Any head can be secured.
　第１熱交換器１０９の下端が第２熱交換器１１０の下端よりも下方に位置することで、第１水受皿１１１よりも第２水受皿１１２の方が上方に位置している。第１水受皿１１１の底面と第２水受皿１１２の底面との高低差は、第２水受皿１１２に滴下されるドレン水が連通部１１４を通じて第１水受皿１１１へと流下する程度あればよい。望ましくは、排水口１１５を備える第１水受皿１１１の底部にヘドロ状のスライムが発生した場合にも、ドレン水によって排水口１１５に対してヘドロ状のスライムを押し流すのに必要なヘッドを確保できるものであればよい。 Since the lower end of the first heat exchanger 109 is positioned below the lower end of the second heat exchanger 110 , the second water tray 112 is positioned higher than the first water tray 111 . The height difference between the bottom surface of the first water receiving plate 111 and the bottom surface of the second water receiving plate 112 is sufficient to allow the drain water dripping onto the second water receiving plate 112 to flow down to the first water receiving plate 111 through the communicating portion 114. . Desirably, even when sludge-like slime occurs at the bottom of the first water receiving tray 111 having the drain port 115, a head necessary for washing the sludge-like slime away from the drain port 115 by the drain water can be secured.

　以上のように構成された空気調和機２００について、以下その動作、作用を説明する。 [2-2 Operation]
The operation and action of the air conditioner 200 configured as described above will be described below.
　熱交換時に第２熱交換器１１０の表面に発生するドレン水は、第２水受皿１１２に滴下し、さらに第２水受皿１１２よりも下方に位置する第１水受皿１１１へと連通部１１４を通じて流下する。第２水受皿１１２から第１水受皿１１１へ到達したドレン水、および熱交換時に第１熱交換器１０９の表面に発生するドレン水は、第１水受皿１１１の底部に備えられた排水口１１５から筐体１０５の外へ排出される。 Drain water generated on the surface of the second heat exchanger 110 during heat exchange drips onto the second water receiving plate 112 and then flows through the communicating portion 114 to the first water receiving plate 111 located below the second water receiving plate 112 . flow down Drain water reaching the first water receiving tray 111 from the second water receiving tray 112 and drain water generated on the surface of the first heat exchanger 109 during heat exchange are discharged through a drain port 115 provided at the bottom of the first water receiving tray 111 . is discharged to the outside of the housing 105 .
　この際、第２水受皿１１２と第１水受皿１１１との間には高低差があるため、ドレン水は第２水受皿１１２および第１水受皿１１１に滞留せずに排水口１１５に向かい、排水口１１５を通じて筐体１０５の外へ排出される。 At this time, since there is a difference in height between the second water receiving tray 112 and the first water receiving tray 111, the drain water does not stay in the second water receiving tray 112 and the first water receiving tray 111, but flows toward the drain port 115. It is discharged out of the housing 105 through the drain port 115 .
　〔２－３　効果〕
　以上のように、本実施の形態において、空気調和機２００は、第１熱交換器１０９の下端の高さ位置が、第２熱交換器１１０の下端の高さ位置より下方にある。 [2-3 Effect]
As described above, in the present embodiment, in air conditioner 200 , the height position of the lower end of first heat exchanger 109 is lower than the height position of the lower end of second heat exchanger 110 .
　これにより、第１水受皿１１１と第２水受皿１１２との間の高低差によってドレン水の滞留の抑制を図ることができる。このため、第１水受皿１１１または第２水受皿１１２においてドレン水に雑菌が繁殖することが抑制される。また、ドレン水と塵埃とが混ざり合って生じるヘドロ状のスライムの発生が抑制される。従って、空気調和機２００を清潔に維持することができる。また、上方に位置する第２水受皿１１２の壁の上端と、下方に位置する第１水受皿１１１の底部との間の高低差が、排水口１１５におけるヘッドとなり得る。従って、排水口１１５を備える第１水受皿１１１の底部にヘドロ状のスライムが発生した場合にも、ドレン水によってヘドロ状のスライムを押し流すのに必要なヘッドが確保されるため、ドレン水の排水性を向上することができる。 As a result, the retention of drain water can be suppressed due to the height difference between the first water receiving tray 111 and the second water receiving tray 112 . Therefore, the propagation of bacteria in the drain water in the first water receiving tray 111 or the second water receiving tray 112 is suppressed. In addition, generation of sludge-like slime caused by mixing of drain water and dust is suppressed. Therefore, the air conditioner 200 can be kept clean. Also, the height difference between the upper end of the wall of the second water tray 112 positioned above and the bottom of the first water tray 111 positioned below can be the head of the drain port 115 . Therefore, even if sludge-like slime occurs at the bottom of the first water receiving tray 111 having the drain port 115, the head necessary for washing away the sludge-like slime is secured by the drain water. can improve sexuality.
　さらに、第１熱交換器１０９の下端が第２熱交換器１１０の下端よりも下方に位置することで、第１熱交換器１０９と正面１０４および上面１０３との間隔を広げることができる。すなわち、第１熱交換器１０９の上方の空間を大きくすることができる。このため、電源基盤や制御基板、各種センサ、又は空気清浄ユニットなどの空気調和機２００に必要な構造物１１６を、省エネ性を損なうことなく筐体１０５内に配置することができる。なお、構造物１１６は１つでも複数でもよく、ここに列挙したものに限定するものではない。 Furthermore, by positioning the lower end of the first heat exchanger 109 below the lower end of the second heat exchanger 110, the distance between the first heat exchanger 109 and the front face 104 and top face 103 can be widened. That is, the space above the first heat exchanger 109 can be enlarged. Therefore, the structures 116 necessary for the air conditioner 200, such as a power supply board, a control board, various sensors, and an air cleaning unit, can be arranged in the housing 105 without impairing energy saving. Note that the number of structures 116 may be one or more, and the number of structures 116 is not limited to those listed here.
