　図４及び図５に示すように、熱交換器載置台４５は、底面部４０と側壁部５０との間に設けられている。例えば、熱交換器載置台４５は、底面部４０及び側壁部５０の塑性加工により、底面パネル４に一体形成されている。熱交換器載置台４５は、側壁部５０の面に接続された載置面４５ａと、底面部４０に接続された支持面４５ｂとを有している。熱交換器載置台４５は、載置面４５ａと支持面４５ｂとの間を連結する曲面４５ｃを有している。図４及び図５では、熱交換器載置台４５の構造の位置関係をより明確にすべく、曲面４５ｃの位置がドットパターンで概略的に示されている。 As shown in FIGS. 4 and 5, the heat exchanger mounting table 45 is provided between the bottom surface portion 40 and the side wall portion 50. For example, the heat exchanger mounting table 45 is integrally formed on the bottom panel 4 by plastic working of the bottom portion 40 and the side wall portion 50. The heat exchanger mounting table 45 has a mounting surface 45 a connected to the surface of the side wall portion 50 and a support surface 45 b connected to the bottom surface portion 40. The heat exchanger mounting table 45 has a curved surface 45c that connects the mounting surface 45a and the supporting surface 45b. 4 and 5, the position of the curved surface 45c is schematically shown by a dot pattern in order to clarify the positional relationship of the structure of the heat exchanger mounting table 45.

It is inclined in a direction away from the surface 45a.
　熱交換器載置台４５は、側壁部５０に沿って延在する第１排水溝４５ｄを有している。すなわち、第１排水溝４５ｄは、側壁部５０と熱交換器載置台４５との間を側壁部５０に沿って延在する凹部であり、熱交換器載置台４５の載置面４５ａに設けられている。第１排水溝４５ｄの端部４５ｄ１、４５ｄ２のうち、少なくとも一方は、支持面４５ｂを介して、ドレンパン部４９の排水路４９ｂと連通している。なお、第１排水溝４５ｄの底部４５ｄ３は、底面部４０に対して平行であってもよいし、底面部４０に設けられたドレンパン部４９に向かって傾斜していてもよい。第１排水溝４５ｄの底部４５ｄ３は、ドレンパン部４９に向かって傾斜させることにより、底面部４０に対して平行な場合と比較して、第１排水溝４５ｄにおける、ドレン水の排水性を向上させることができる。 The heat exchanger mounting table 45 has a first drain groove 45d extending along the side wall portion 50. That is, the first drain groove 45 d is a recess extending along the side wall portion 50 between the side wall portion 50 and the heat exchanger mounting base 45, and is provided on the mounting surface 45 a of the heat exchanger mounting base 45. ing. At least one of the ends 45d1 and 45d2 of the first drainage groove 45d communicates with the drainage channel 49b of the drain pan 49 via the support surface 45b. The bottom portion 45d3 of the first drainage groove 45d may be parallel to the bottom surface portion 40, or may be inclined toward the drain pan portion 49 provided on the bottom surface portion 40. The bottom portion 45d3 of the first drain groove 45d is inclined toward the drain pan portion 49, so that drainage water drainage in the first drain groove 45d is improved as compared with the case where the bottom portion 45d3 is parallel to the bottom surface portion 40. be able to.
　また、熱交換器載置台４５は、第１排水溝４５ｄと連通し、側壁部５０から離れる方向に延在する第２排水溝４５ｅを有している。すなわち、第２排水溝４５ｅは、熱交換器載置台４５の載置面４５ａに設けられており、側壁部５０から離れる方向に延びて、熱交換器載置台４５の載置面４５ａを分割する凹部である。第２排水溝４５ｅの一方の端部４５ｅ１は、第１排水溝４５ｄと連通しており、第２排水溝４５ｅの他方の端部４５ｅ２は、支持面４５ｂを介して、ドレンパン部４９の排水路４９ｂと連通している。なお、図４及び図５では、第２排水溝４５ｅの幅Ｄは、第２排水溝４５ｅの一方の端部４５ｅ１と他方の端部４５ｅ２との間で同一幅となっている。 The heat exchanger mounting table 45 also has a second drain groove 45e communicating with the first drain groove 45d and extending in a direction away from the side wall portion 50. That is, the second drain groove 45e is provided on the mounting surface 45a of the heat exchanger mounting table 45, extends in the direction away from the side wall portion 50, and divides the mounting surface 45a of the heat exchanger mounting table 45. It is a recess. One end portion 45e1 of the second drain groove 45e communicates with the first drain groove 45d, and the other end portion 45e2 of the second drain groove 45e is connected to the drain passage of the drain pan portion 49 via the support surface 45b. It communicates with 49b. 4 and 5, the width D of the second drain groove 45e is the same between the one end portion 45e1 and the other end portion 45e2 of the second drain groove 45e.
　図６は、図５の熱交換器載置台４５のＡ－Ａ断面を概略的に示した断面図である。図５のＡ－Ａ断面は、底面パネル４の底面部４０に対し垂直な断面である。図６では、第１排水溝４５ｄ及び第２排水溝４５ｅの構造を説明する関係上、側壁部５０、熱交換器載置台４５の載置面４５ａ等の主要な構成のみを概略的に示している。また、図６では、ドレン水６０が点線で模式的に示されている。また、図６では、底面パネル４の底面部４０の断面と平行な直線Ｌ１が一点鎖線で示されており、第２排水溝４５ｅの底部４５ｅ３の断面の線分の延長線Ｌ２が二点鎖線で示されている。また、図６では、直線Ｌ１に対する延長線Ｌ２の角度は、底面部４０に対し垂直なＡ－Ａ断面における、底面部４０に対する第２排水溝４５ｅの底部４５ｅ３の傾斜角θを表している。 FIG. 6 is a sectional view schematically showing an AA section of the heat exchanger mounting table 45 of FIG. 5 is a cross section perpendicular to the bottom surface portion 40 of the bottom panel 4. In FIG. 6, in order to explain the structure of the first drain groove 45d and the second drain groove 45e, only the main components such as the side wall portion 50 and the mounting surface 45a of the heat exchanger mounting base 45 are schematically shown. There is. Further, in FIG. 6, the drain water 60 is schematically shown by a dotted line. Further, in FIG. 6, a straight line L1 parallel to the cross section of the bottom surface portion 40 of the bottom surface panel 4 is shown by a one-dot chain line, and an extension line L2 of a line segment of the cross section of the bottom portion 45e3 of the second drainage groove 45e is a two-dot chain line. Indicated by. Further, in FIG. 6, the angle of the extension line L2 with respect to the straight line L1 represents the inclination angle θ of the bottom portion 45e3 of the second drainage groove 45e with respect to the bottom surface portion 40 in the AA cross section perpendicular to the bottom surface portion 40.
　図６に示されるように、第２排水溝４５ｅの底部４５ｅ３は、側壁部５０から離れる方向において、底面部４０に向かって傾斜している。この構成によれば、第１排水溝４５ｄに滞留したドレン水６０は、熱交換器載置台４５の載置面４５ａに到達する前に、熱交換器載置台４５の第２排水溝４５ｅから排水される。したがって、上述の構成によれば、第１排水溝４５ｄにドレン水６０が滞留することを抑制でき、ドレン水６０が凍結した氷が、熱交換器載置台４５に形成されるのを防ぐことができる。以上のことから、上述の構成によれば、熱交換器１１の耐久性を確保可能な底面パネル４及び空気調和装置の室外機１００を提供できる。 As shown in FIG. 6, the bottom portion 45e3 of the second drainage groove 45e is inclined toward the bottom surface portion 40 in the direction away from the side wall portion 50. According to this configuration, the drain water 60 accumulated in the first drain groove 45d is drained from the second drain groove 45e of the heat exchanger mounting table 45 before reaching the mounting surface 45a of the heat exchanger mounting table 45. To be done. Therefore, according to the above-described configuration, it is possible to prevent the drain water 60 from staying in the first drainage groove 45d, and prevent the frozen ice of the drain water 60 from being formed on the heat exchanger mounting table 45. it can. From the above, according to the above-described configuration, it is possible to provide the bottom panel 4 and the outdoor unit 100 of the air conditioner capable of ensuring the durability of the heat exchanger 11.
　また、図６に示すように、第２排水溝４５ｅから排水されたドレン水６０は、支持面４５ｂを介して、ドレンパン部４９の排水路４９ｂに排水できるため、底面パネル４及び空気調和装置の室外機１００の排水性能を向上させることができる。 Further, as shown in FIG. 6, since the drain water 60 drained from the second drain groove 45e can be drained to the drainage channel 49b of the drain pan portion 49 via the support surface 45b, the bottom panel 4 and the air conditioner can be operated. The drainage performance of the outdoor unit 100 can be improved.
　また、底面部４０に対し垂直なＡ－Ａ断面における、底面部４０に対する第２排水溝４５ｅの底部４５ｅ３の傾斜角θは、空気調和装置の室外機１００の設置限界の傾斜面の角度より大きくすることができる。例えば、傾斜角θは５度よりも大きくすることができる。この構成によれば、熱交換器載置台４５の配置された方向が傾斜の下方向となった場合であっても、第２排水溝４５ｅの底部４５ｅ３は、水平面に対し、側壁部５０から離れる方向において、底面部４０に向かって傾斜している。よって、この構成によれば、第１排水溝４５ｄのドレン水６０は、熱交換器載置台４５の側壁部５０の側において、熱交換器載置台４５の載置面４５ａに到達する前に、熱交換器載置台４５の第２排水溝４５ｅから排水される。したがって、上述の構成によれば、空気調和装置の室外機１００が傾斜面に設置された場合であっても、第１排水溝４５ｄにドレン水６０が滞留することを抑制できるため、ドレン水６０が凍結した氷が、熱交換器載置台４５に形成されるのを防ぐことができる。以上のことから、上述の構成によれば、熱交換器１１の耐久性が更に向上した底面パネル４及び空気調和装置の室外機１００を提供できる。 Further, in the AA cross section perpendicular to the bottom surface portion 40, the inclination angle θ of the bottom portion 45e3 of the second drainage groove 45e with respect to the bottom surface portion 40 is larger than the inclination angle of the installation limit of the outdoor unit 100 of the air conditioner. can do. For example, the tilt angle θ can be greater than 5 degrees. According to this configuration, the bottom portion 45e3 of the second drainage groove 45e is separated from the side wall portion 50 with respect to the horizontal plane even when the direction in which the heat exchanger mounting table 45 is arranged is the downward direction of the inclination. In the direction, the bottom surface portion 40 is inclined. Therefore, according to this configuration, the drain water 60 in the first drainage groove 45d, on the side of the side wall portion 50 of the heat exchanger mounting table 45, before reaching the mounting surface 45a of the heat exchanger mounting table 45, It is drained from the second drain groove 45e of the heat exchanger mounting table 45. Therefore, according to the above configuration, even when the outdoor unit 100 of the air conditioner is installed on the inclined surface, it is possible to prevent the drain water 60 from staying in the first drain groove 45d, and thus the drain water 60 It is possible to prevent the frozen ice from being formed on the heat exchanger mounting table 45. From the above, according to the above configuration, it is possible to provide the bottom panel 4 and the outdoor unit 100 of the air conditioner in which the durability of the heat exchanger 11 is further improved.
　図７は、図５の熱交換器載置台４５のＡ－Ａ断面の変形例を概略的に示した断面図である。図７では、底面部４０に対し垂直なＡ－Ａ断面において、第１排水溝４５ｄの底部４５ｄ３は、第２排水溝４５ｅの底部４５ｅ３と同一直線上に配置されている。その他の構成は、図６と同一であるため、説明は省略する。 FIG. 7 is a sectional view schematically showing a modified example of the AA section of the heat exchanger mounting table 45 of FIG. In FIG. 7, the bottom portion 45d3 of the first drainage groove 45d is arranged on the same straight line as the bottom portion 45e3 of the second drainage groove 45e in the AA cross section perpendicular to the bottom surface portion 40. The other configuration is the same as that of FIG. 6, and thus the description is omitted.
　上述の構成によれば、底面部４０に対し垂直な断面において、第１排水溝４５ｄの底部４５ｄ３は、第２排水溝４５ｅの底部４５ｅ３と平滑に連結されるため、第１排水溝４５ｄに滞留するドレン水６０の量を更に低減することができる。したがって、上述の構成によれば、第１排水溝４５ｄにドレン水６０が滞留することを更に抑制できるため、ドレン水６０が凍結した氷が、熱交換器載置台４５に形成されるのをより良好に防ぐことができる。以上のことから、上述の構成によれば、熱交換器１１の耐久性が更に向上した底面パネル４及び空気調和装置の室外機１００を提供できる。 According to the above configuration, in the cross section perpendicular to the bottom surface portion 40, the bottom portion 45d3 of the first drainage groove 45d is smoothly connected to the bottom portion 45e3 of the second drainage groove 45e, and thus stays in the first drainage groove 45d. The amount of drain water 60 used can be further reduced. Therefore, according to the above-described configuration, the drain water 60 can be further prevented from staying in the first drain groove 45d, so that the ice frozen by the drain water 60 is more likely to be formed on the heat exchanger mounting table 45. It can be prevented well. From the above, according to the above configuration, it is possible to provide the bottom panel 4 and the outdoor unit 100 of the air conditioner in which the durability of the heat exchanger 11 is further improved.

That is, the width D2 of the outlet-side end portion 45e2 of the second drain groove 45e is larger than the width D1 of the inlet-side end portion 45e1 of the second drain groove 45e. Further, the width D of the second drain groove 45e gradually increases from one end portion 45e1 on the inlet side of the second drain groove 45e toward the other end portion 45e2 on the outlet side. 8 and 9, the side portions 45e4, 45e5 of the second drain groove 45e have a planar shape, but may have a curved surface shape protruding in the direction of the second drain groove 45e. The other configuration of the heat exchanger mounting table 45 is the same as that of the above-described first embodiment, and thus the description thereof is omitted.
　上述の構成によれば、空気調和装置の室外機１００が傾斜面に設置され、第２排水溝４５ｅの幅方向に傾いた場合であっても、第２排水溝４５ｅの側部４５ｅ４、４５ｅ５のいずれかの面は、側壁部５０から離れる方向に傾斜する。したがって、上述の構成によれば、第２排水溝４５ｅにドレン水が滞留することも抑制できるため、ドレン水が凍結した氷が、熱交換器載置台４５に形成されるのをより良好に防ぐことができる。以上のことから、上述の構成によれば、熱交換器１１の耐久性が更に向上した底面パネル４及び空気調和装置の室外機１００を提供できる。 According to the above configuration, even when the outdoor unit 100 of the air conditioner is installed on the inclined surface and is inclined in the width direction of the second drain groove 45e, the side portions 45e4, 45e5 of the second drain groove 45e are disposed.
