　対向板部６３は、気流が衝突する部位であって、支持部材６の下面を形成している。対向板部６３は、基板部６０の上流側から気流の方向に対して対向するように水平に延出して配置されている。基板部６０から対向板部６３の先端までの長さ（延出量）Ｌ１（例えば、２２～３２ｍｍ程度）は、基板部６０から支持板部６２の先端までの長さ（延出量）Ｌ２よりも小さく形成されている。換言すると、対向板部６３の面積は、支持板部６２の面積よりも、小さい。なお、面積とは、気流に対する正面投影面積といえる。 The opposing plate portion 63 is a portion where the air flow collides, and forms the lower surface of the support member 6. The opposing plate portion 63 is disposed to extend horizontally so as to face the direction of the air flow from the upstream side of the substrate portion 60. The length (extension amount) L1 (for example, about 22 to 32 mm) from the substrate portion 60 to the tip of the opposing plate portion 63 is the length (extension amount) L2 from the substrate portion 60 to the tip of the support portion 62 It is smaller than that. In other words, the area of the opposing plate portion 63 is smaller than the area of the support plate portion 62. In addition, an area can be said to be a front projection area with respect to an air flow.
　図４に示すように、蓋板部６１は、正面視して、略コ字状（略Ｕ字状）に折り曲げられた支持部材６の支持板部６２と、対向板部６３との間に配置するように、平面視してＬ字状に折り曲げ形成された矩形の突出片からなる。各蓋板部６１の中央部には、支持部材６を前側ステー７６及び後側ステー７７に固定するための支持部材固定ねじ６８が挿入されるねじ挿入孔６１ａが形成されている（図３参照）。 As shown in FIG. 4, the cover plate portion 61 is located between the support plate portion 62 of the support member 6 and the opposing plate portion 63 which are bent in a substantially U shape (substantially U shape) in a front view. It consists of a rectangular projecting piece bent and formed in an L shape in plan view so as to be disposed. At the central portion of each lid plate portion 61, a screw insertion hole 61a is formed in which a support member fixing screw 68 for fixing the support member 6 to the front stay 76 and the rear stay 77 is inserted (see FIG. 3). ).
≪作用≫
　次に、図１～図５を参照して、本発明の実施形態に係る空気調和機の室外機の作用を説明する。 «Function»
Next, the operation of the outdoor unit of the air conditioner according to the embodiment of the present invention will be described with reference to FIGS.
　図１に示すように、空気調和機の室外機１は、モータ５が回転駆動すると、モータ軸５１（図４参照）を介してファン４が回転する。すると、ファン４は、室外機１の外周の外気を左右後側の三面から室外機１内に吸引して、熱交換器２（図３参照）で熱交換を行って、ベルマウス兼シュラウド７８の上側開口部から上方向（矢印ａ方向）へと送って大気中に排出する。このため、図３に示すように、ファン４によって筐体７内に吸引された空気（矢印ｂ）は、熱交換器２を流通して冷媒と空気の熱交換を促進させる。 As shown in FIG. 1, when the motor 5 is driven to rotate, the outdoor unit 1 of the air conditioner rotates the fan 4 via the motor shaft 51 (see FIG. 4). Then, the fan 4 sucks the outside air of the outer periphery of the outdoor unit 1 into the outdoor unit 1 from the three sides on the left and right rear sides, and performs heat exchange with the heat exchanger 2 (see FIG. 3). The air is sent to the upper direction (the direction of arrow a) from the upper opening of the For this reason, as shown in FIG. 3, the air (arrow b) sucked into the housing 7 by the fan 4 flows through the heat exchanger 2 to promote heat exchange between the refrigerant and the air.
　図１に示すように、筐体７内では、下方から上方へ向かって空気が流れるので、支持部材６が空気の流れ（気流）に対向する状態に配置されている。
　図５に示すように、縦断面視してコ字状（略Ｕ字状）に形成された支持部材６は、室外機１（図１参照）内の気流に対向する対向板部６３の面積（延出量）が、対向板部６３よりも下流側に配置された支持板部６２の面積（延出量）よりも、小さく形成されている。このように支持部材６は、室外機１（図１参照）の内部の気流に対向する面の面積（延出量）が小さく形成されていることによって、対向板部６３に衝突する空気の衝突量を小さくすることができる。 As shown in FIG. 1, in the housing 7, air flows from the lower side to the upper side, so the support member 6 is disposed in a state of facing the air flow (air flow).
As shown in FIG. 5, the support member 6 formed in a U-shape (approximately U-shape) in a longitudinal cross-sectional view has an area of the opposing plate portion 63 opposed to the air flow in the outdoor unit 1 (see FIG. 1). The (amount of extension) is formed smaller than the area (amount of extension) of the support plate portion 62 disposed downstream of the opposing plate portion 63. As described above, the support member 6 is formed such that the area (amount of extension) of the surface facing the air flow inside the outdoor unit 1 (see FIG. 1) is small, so that the collision of air colliding with the opposing plate portion 63 The amount can be reduced.
　また、支持部材６に対して当たるように下方向から上方向に向かって流れて来る空気は、対向板部６３に衝突し、左右方向に分かれるように変向されて、左右方向に広がるように下流方向に流れる。このため、支持部材６は、下流方向へ流れる空気の流入角度を緩やかにして、支持板部６２を避けるように流すことができる。 Further, the air flowing from the lower to the upper side so as to hit the support member 6 collides with the opposing plate portion 63, is diverted so as to be divided in the left and right direction, and spreads in the left and right direction. It flows in the downstream direction. Therefore, the support member 6 can flow so as to avoid the support plate portion 62 by making the inflow angle of the air flowing in the downstream direction gentle.
　また、支持部材６は、下流側の支持板部６２の面積が対向板部６３の面積よりも広く形成されているので、しっかりとモータ５（モータブラケット５３）を支持することができる。また、支持部材６は、空気（矢印ｃ，ｄ）を徐々に左右方向に広がるように下流方向に流すことができるので、空気をスムーズに流すことができるため、空気抵抗（抗力係数）を小さくすることができる。また、基板部６０は、垂直方向に形成されていることによって、気流を整流させる機能を果す。 Further, since the area of the support plate portion 62 on the downstream side is formed wider than the area of the opposing plate portion 63, the support member 6 can support the motor 5 (motor bracket 53) firmly. Further, since the support member 6 can flow air (arrows c and d) in the downstream direction so as to gradually spread in the left and right direction, air can flow smoothly, so the air resistance (drag coefficient) is small. can do. In addition, the substrate portion 60 functions to rectify the air flow by being formed in the vertical direction.
　このように支持部材６は、空気抵抗を小さくすることができるので、ファン４を駆動のためのモータ５の入力電流を減少させて、室外機１のファン４の性能を高くすることができる（図１参照）。また、支持部材６は、空気抵抗を低減させたことにより、気流が支持部材６に当たることによって発生する騒音（風の音）を低減させることができる。 Thus, since the support member 6 can reduce the air resistance, it is possible to reduce the input current of the motor 5 for driving the fan 4 and to enhance the performance of the fan 4 of the outdoor unit 1 ( See Figure 1). Moreover, the support member 6 can reduce the noise (sound of a wind) which generate | occur | produces when airflow falls on the support member 6 by reducing air resistance.
　また、図４あるいは図５に示すように、支持部材６を製造する場合は、まず、１枚の板金を切断して、基板部６０、支持板部６２、対向板部６３及び蓋板部６１を形成する切断工程を行う。次に、支持板部６２に雌ねじ部（図示省略）を形成するねじ形成工程と、蓋板部６１にねじ挿入孔６１ａを形成する穴あけ工程と、を行う。続いて、基板部６０に対して、支持板部６２、対向板部６３及び蓋板部６１を直角に折り曲げる曲げ工程を行うことで、支持部材６を完成させることができる。 Further, as shown in FIG. 4 or FIG. 5, when manufacturing the support member 6, first, one sheet metal is cut, and the substrate portion 60, the support plate portion 62, the counter plate portion 63, and the lid plate portion 61. Perform a cutting process to form Next, a screw forming step of forming a female screw portion (not shown) in the support plate portion 62 and a drilling step of forming a screw insertion hole 61 a in the lid plate portion 61 are performed. Subsequently, the supporting member 6 can be completed by performing a bending process of bending the support plate portion 62, the counter plate portion 63, and the lid plate portion 61 at right angles with respect to the substrate portion 60.
　このように支持部材６は、１枚の板金を切断して折り曲げることによって、容易にプレス加工して製造することができる。このため、支持部材６は、製造工程及び部品点数が少なく、短時間で製造することができるため、コストダウンを図ることができる。 As described above, the support member 6 can be easily pressed and manufactured by cutting and bending one sheet metal. For this reason, since the supporting member 6 can be manufactured in a short time with a small number of manufacturing processes and parts, cost can be reduced.
　このようにして形成された支持部材６は、基板部６０の下流側端部及び上流側端部の曲げ部６ａ，６ｂが折り曲げて、縦断面視して略コ字状（略Ｕ字状）に形成されていることによって、基板部６０の上下端部に２つの稜線が形成されている。このため、支持部材６は、上下方向の荷重に対する支持強度が向上されて、送風機４０（図１参照）をしっかりと支持することが可能な強度を確保することができる。 The supporting member 6 formed in this manner is substantially U-shaped (substantially U-shaped) in a longitudinal cross-sectional view by bending the bent portions 6a and 6b at the downstream end and the upstream end of the substrate portion 60. The two ridge lines are formed at the upper and lower end portions of the substrate portion 60 by forming them. For this reason, the supporting strength with respect to the load of the up-down direction is improved, and the supporting member 6 can ensure the intensity | strength which can support the air blower 40 (refer FIG. 1) firmly.

［第１変形例］
　図６は、室外機の支持部材の第１変形例を示す拡大縦断面図である。
　前記実施形態は、支持部材６（図５参照）の一例として、縦断面視してコ字状（略Ｕ字状）のものを例に挙げて説明したが、これに限定されるものではない。図６に示すように、支持部材６Ａは、対向板部６３Ａの上流側端部を上流側方向に折り曲げて形成されて、空気の流れを整流させる機能を果す上流側整流板部６４Ａを有するものであってもよい。 First Modification
FIG. 6 is an enlarged vertical sectional view showing a first modified example of the support member of the outdoor unit.
Although the said embodiment mentioned and demonstrated the thing of a U-shape (substantially U-shape) to a longitudinal cross-sectional view as an example of the supporting member 6 (refer FIG. 5), it is not limited to this. . As shown in FIG. 6, the supporting member 6A is formed by bending the upstream end of the opposing plate 63A in the upstream direction, and has an upstream rectifying plate 64A that functions to rectify the flow of air. It may be
　この場合、支持部材６Ａには、対向板部６３Ａの左端部に形成された曲げ部６Ａａを、上流側方向に直角に折り曲げて下側方向に延びる上流側整流板部６４Ａが形成されている。対向板部６３Ａの右端から左端までの長さ（延出量）Ｌ３は、支持板部６２Ａの右端から左端までの長さ（延出量）Ｌ２の約半分程度の長さ（延出量）にする。上流側整流板部６４Ａは、下面視して支持部材６Ａの中央部に配置されている。 In this case, the support member 6A is provided with an upstream side straightening plate portion 64A which extends downward by bending the bent portion 6Aa formed at the left end portion of the opposing plate portion 63A at a right angle to the upstream side direction. The length (extension amount) L3 from the right end to the left end of the opposing plate 63A is about half the length (extension amount) L2 from the right end to the left end of the support plate 62A (extension amount) Make it The upstream rectifying plate portion 64A is disposed at the central portion of the support member 6A as viewed from below.
　したがって、支持部材６Ａの基板部６０Ａ、支持板部６２Ａ、対向板部６３Ａ、及び、上流側整流板部６４Ａは、側面視して全体が逆三角形にイメージした範囲の内側に配置されるように配置されて、下流に流れる気流を徐々に横方向に拡げて、空気抵抗が小さくなるように配置されている。 Accordingly, the substrate 60A, the support plate 62A, the counter plate 63A, and the upstream rectifying plate 64A of the support member 6A are disposed within the range in which the whole is imaged as an inverted triangle in a side view. It is arranged so that the air flow flowing downstream gradually spreads laterally to reduce air resistance.
　このように形成された支持部材６Ａに対して流れて来る空気は、上流側整流板部６４Ａの先端面に衝突して変向されて、基板部６０Ａ側（矢印ｅ側）と、支持板部６２Ａの先端側（矢印ｆ側）と、に向かう流れに二分される。二分された空気は、上流方向に延びる上流側整流板部６４Ａにある程度沿った流れとなって、下流方向に流れる。 The air flowing to the support member 6A formed in this way collides with the tip end surface of the upstream rectification plate portion 64A and is deflected, and the substrate portion 60A side (arrow e side), the support plate portion The flow toward the tip end side (arrow f side) of 62A is divided into two. The divided air flows to a downstream direction in a flow along an upstream side straightening vane portion 64A extending in the upstream direction.
　上流側整流板部６４Ａの先端面で変向された空気は、支持板部６２Ａに対して流入角度が緩やか角度となって流れるので、支持板部６２Ａに衝突する衝突量が減少させるように流れる。 The air deflected at the tip end face of the upstream side straightening vane portion 64A flows so that the inflow angle becomes a gentle angle with respect to the support plate portion 62A, so that the amount of collisions colliding with the support plate portion 62A decreases. .
　また、上流側整流板部６４Ａの先端面で変向された空気の流れ（矢印ｅ，ｆ）は、基板部６０Ａに沿って下流側に流れる流れとなる。そのため、支持部材６Ａの各面（上流側整流板部６４Ａ、対向板部６３Ａ、基板部６０Ａ及び支持板部６２Ａ）に対し衝突する空気の衝突量は、実施形態の支持部材６よりも少なく、騒音及び空気抵抗（抗力係数）が小さいため、空気が流れ易くなっている。その結果、送風機４０（図１参照）を駆動させるための入力電流を低減させることができる。 Further, the flow of the air (arrows e and f) deflected at the tip end face of the upstream side rectifying plate portion 64A is a flow flowing to the downstream side along the substrate portion 60A. Therefore, the amount of collision of air with respect to each surface of the support member 6A (the upstream side rectifying plate portion 64A, the opposing plate portion 63A, the substrate portion 60A, and the support plate portion 62A) is smaller than that of the supporting member 6 of the embodiment. The low noise and low air resistance (drag coefficient) make it easy for the air to flow. As a result, the input current for driving the blower 40 (see FIG. 1) can be reduced.
［第２変形例］
　図７は、モータを支持する支持部材の第２変形例を示す拡大縦断面図である。
　図７に示すように、支持部材６Ｂは、上流側整流板部６４Ｂの上流側端部を下流側方向に折り曲げて形成されたＲ部ｒ１と、Ｒ部ｒ１から下流方向に折り畳むようにして形成された折返板部６５Ｂと、を有するものであってもよい。 Second Modified Example
FIG. 7 is an enlarged vertical sectional view showing a second modified example of the support member for supporting the motor.
As shown in FIG. 7, the supporting member 6B is formed so as to be folded in the downstream direction from the R portion r1 formed by bending the upstream side end portion of the upstream rectifying plate portion 64B in the downstream side direction and the R portion r1. And the folded back plate portion 65B.
　この場合、Ｒ部ｒ１は、前記第１変形例の上流側整流板部６４Ａ（図６参照）と同一の上流側整流板部６４Ｂの上流側を延ばして、下流側に１８０度折り返すようにして形成された折り曲げ部である。Ｒ部ｒ１の外周面は、断面視して半円形状に形成されている。Ｒ部ｒ１は、下面視して支持部材６Ｂの中央部に配置されている。Ｒ部ｒ１は、空気の流れを滑らかにする機能と、強度を向上させる機能と、を果す。
　折返板部６５Ｂは、上流側整流板部６４Ｂの左側に、上流側整流板部６４Ｂに沿って下流側方向に平行に配置されている。 In this case, the R portion r1 extends the upstream side of the upstream rectifying plate portion 64B which is the same as the upstream rectifying plate portion 64A (see FIG. 6) of the first modification, and folds it 180 degrees downstream. It is a formed bent part. The outer peripheral surface of the R portion r1 is formed in a semicircular shape in cross section. The R portion r1 is disposed at the central portion of the support member 6B in a bottom view. The R portion r1 functions to smooth the air flow and to improve the strength.
The folded-back plate portion 65B is disposed on the left side of the upstream flow straightening vane portion 64B in parallel with the downstream side direction along the upstream flow straightening vane portion 64B.
　このように形成された支持部材６Ｂに対して流れて来る空気は、上流側端部のＲ部ｒ１に衝突して流れる方向が変向され、上流側整流板部６４Ｂ及び基板部６０Ｂに沿って流れる流れ（矢印ｇ）と、折返板部６５Ｂに沿って流れる流れ（矢印ｈ）と、に分散される。 The air flowing to the support member 6B formed in this way collides with the R portion r1 of the upstream end and the flow direction is changed, and the air flows along the upstream current plate portion 64B and the substrate portion 60B. It is dispersed into a flowing flow (arrow g) and a flow (arrow h) flowing along the turnaround plate portion 65B.
　Ｒ部ｒ１で流れる方向が支持部材６Ｂの右側に変向された空気の流れ（矢印ｇ）は、対向板部６３Ｂに対して流入角度が緩やかとなる。このため、対向板部６３Ｂへの空気の衝突量は、小さくなる。Ｒ部ｒ１で流れる方向が支持部材６Ｂの左側に変向された空気の流れ（矢印ｈ）は、支持板部６２Ｂを避けるように、Ｒ部ｒ１から斜め左上方向に向かって流れる流れとなる。 The flow (arrow g) of the air whose direction of flow at the R portion r1 is deflected to the right of the support member 6B has a gentle inflow angle with respect to the opposing plate portion 63B. For this reason, the collision amount of air to the opposing plate portion 63B is reduced. The air flow (arrow h) whose flow direction is diverted to the left side of the support member 6B in the R portion r1 is a flow flowing obliquely from the R portion r1 toward the upper left so as to avoid the support plate portion 62B.
　このため、支持部材６Ｂの各面に対して衝突する空気の衝突量は、少なくなる。これにより、支持部材６Ｂは、空気抵抗及び騒音も小さくなり、ファン４を駆動させるためのモータ５の入力電流を削減することができる（図１参照）。 For this reason, the collision amount of the air colliding with each surface of the support member 6B is reduced. Thus, the support member 6B also reduces air resistance and noise, and can reduce the input current of the motor 5 for driving the fan 4 (see FIG. 1).
［第３変形例］
　図８は、モータを支持する支持部材の第３変形例を示す拡大縦断面図である。
　図８に示すように、支持部材６Ｃは、上流側整流板部６４Ｃの上流側端部を対向板部６３Ｃに沿うように折り曲げて形成された上流側対向板部６６Ｃを有するものであってもよい。 Third Modification
FIG. 8 is an enlarged vertical sectional view showing a third modified example of the support member for supporting the motor.
As shown in FIG. 8, even if the supporting member 6C has an upstream opposing plate 66C formed by bending the upstream end of the upstream rectifying plate 64C along the opposing plate 63C. Good.
　この場合、支持部材６Ｃは、上流側整流板部６４Ｃの上流側端部の曲げ部６Ｃａを、気流方向に対して対向する向きに折り曲げて形成された上流側対向板部６６Ｃを有している。上流側対向板部６６Ｃは、気流方向に形成された上流側整流板部６４Ｃに対して、直角に左右方向に向けて形成されている。上流側対向板部６６Ｃは、下面視して支持部材６Ｃの略中央部に配置されている。上流側対向板部６６Ｃの面積（延出量）は、対向板部６３Ｃの面積（延出量）よりも小さく形成されている。対向板部６３Ｃの面積（延出量）は、支持板部６２Ｃの面積（延出量）よりも小さく形成されている。 In this case, the supporting member 6C has an upstream opposing plate portion 66C formed by bending the bent portion 6Ca at the upstream end of the upstream rectifying plate portion 64C in the direction opposite to the air flow direction. . The upstream opposing plate portion 66C is formed at right angles in the left-right direction with respect to the upstream rectifying plate portion 64C formed in the air flow direction. The upstream facing plate portion 66C is disposed substantially at the center of the support member 6C in a bottom view. The area (extension amount) of the upstream side opposing plate portion 66C is formed smaller than the area (extension amount) of the opposing plate portion 63C. The area (extension amount) of the opposing plate portion 63C is formed smaller than the area (extension amount) of the support plate portion 62C.
　このように、側面視して略逆Ｓ字状に形成された支持部材６Ｃに対して流れて来る空気は、上流側対向板部６６Ｃに衝突して流れる方向が変向される。変向された空気は、対向板部６３Ｃ及び基板部６０Ｃに向かって流入角度が緩やかになった空気の流れ（矢印ｉ）と、上流側整流板部６４Ｃに沿うように支持板部６２Ｃの左端部側に向かって流れる空気の流れ（矢印ｊ）と、に分散される。また、側面視して略逆Ｓ字状の支持部材６Ｃは、曲げ部６Ｃａ及び稜線が多く形成されているので、全体の強度を向上させることができる。 As described above, the air flowing to the support member 6C formed in a substantially inverted S-shape in a side view collides with the upstream side opposing plate portion 66C and is diverted in the flowing direction. The diverted air has an air flow (arrow i) whose inflow angle has become gentle toward the opposing plate portion 63C and the base plate portion 60C, and the left end of the support plate portion 62C so as to be along the upstream side rectifying plate portion 64C. It is dispersed in the air flow (arrow j) flowing toward the part side. In addition, since the bending portion 6Ca and the ridge line are formed in a large amount in the substantially inverted S-shaped supporting member 6C in side view, the overall strength can be improved.
　上流側対向板部６６Ｃで流れる方向が支持部材６Ｃの右側に変向された空気の流れ（矢印ｉ）は、支持板部６２Ｃを避けるようにして下流方向に流れる。上流側対向板部６６Ｃで流れる方向が支持部材６Ｃの左側に変向された空気の流れ（矢印ｊ）は、対向板部６３Ｃに対して流入角度が緩やかとなっており、対向板部６３Ｃの下面のへの空気の衝突量が小さくなる。 The air flow (arrow i) whose flow direction is diverted to the right side of the support member 6C by the upstream opposing plate portion 66C flows in the downstream direction so as to avoid the support plate portion 62C. The air flow (arrow j) whose direction of flow in the upstream facing plate portion 66C is diverted to the left side of the support member 6C (arrow j) has a gentle inflow angle with respect to the facing plate portion 63C. The amount of air collision with the lower surface decreases.
　このため、支持部材６Ｃの各面に対して衝突する空気の衝突量は、少なくなる。これにより、支持部材６Ｃは、空気抵抗も小さくなり、ファン４を駆動のためのモータ５の入力電流を削減することができる（図１参照）。 For this reason, the collision amount of the air colliding with each surface of the support member 6C is reduced. Accordingly, the support member 6C also reduces the air resistance, and the input current of the motor 5 for driving the fan 4 can be reduced (see FIG. 1).
［第４変形例］
　図９は、モータを支持する支持部材の第４変形例を示す拡大縦断面図である。
　図９に示すように、支持部材６Ｄは、支持板部６２Ｄから下流方向に折り曲げられた下流側整流板部６７Ｄを有しているものであってもよい。 Fourth Modified Example
FIG. 9 is an enlarged vertical sectional view showing a fourth modification of the support member for supporting the motor.
As shown in FIG. 9, the support member 6D may have a downstream side flow plate portion 67D which is bent in the downstream direction from the support plate portion 62D.
　この場合、支持部材６Ｄは、支持板部６２Ｄの左端部の曲げ部６Ｄａを、下流方向側に折り曲げて、下流方向に延びる下流側整流板部６７Ｄを有している。下流側整流板部６７Ｄは、気流方向に対して直交する方向（水平方向）に形成された支持板部６２Ｄに対して、直角に上方向に向けて形成されている。下流側整流板部６７Ｄは、平面視して支持部材６Ｄの左端に配置されている。 In this case, the support member 6D has a downstream straightening plate portion 67D which is bent in the downstream direction by bending the bent portion 6Da at the left end of the support plate portion 62D in the downstream direction. The downstream flow straightening plate portion 67D is formed to extend upward at a right angle with respect to a support plate portion 62D formed in a direction (horizontal direction) orthogonal to the air flow direction. The downstream rectifying plate portion 67D is disposed at the left end of the support member 6D in plan view.
　このように形成された支持部材６Ｄに対して流れて来る空気は、対向板部６３Ｄに衝突して流れる方向が左右（矢印ｋ，ｍ）方向に変向される。対向板部６３Ｄの右側に流れた空気（矢印ｋ）は、基板部６０Ｄに沿って下流側方向に流れる。対向板部６３Ｄの左側に流れた空気（矢印ｍ）は、支持板部６２Ｄを避けるように下流側に流れ、下流側整流板部６７Ｄの左側面に整流されて下流側整流板部６７Ｄに沿って下流側に流れる。 The air flowing to the support member 6D formed in this way is deflected in the right and left direction (arrows k and m) in the flow direction of the air that collides with the opposing plate portion 63D and flows. The air (arrow k) that has flowed to the right of the opposing plate portion 63D flows in the downstream direction along the substrate portion 60D. The air (arrow m) that has flowed to the left of the opposing plate 63D flows downstream so as to avoid the support plate 62D, and is rectified to the left side of the downstream rectifying plate 67D to be along the downstream rectifying plate 67D. Flow downstream.
　このため、支持部材６Ｄの各面に対して衝突する空気の衝突量は、少なくなる。支持部材６Ｄは、下流側を整流することによって空気抵抗を小さくすることができるので、ファン４を駆動のためのモータ５の入力電流を削減することができる（図１参照）。 For this reason, the collision amount of the air colliding with each surface of the support member 6D is reduced. Since the support member 6D can reduce the air resistance by rectifying the downstream side, the input current of the motor 5 for driving the fan 4 can be reduced (see FIG. 1).
［第５変形例］
　図１０は、モータを支持する支持部材の第５変形例を示す拡大縦断面図である。
　図１０に示すように、上流側整流板部６４Ｅを有する支持部材６Ｅは、前記第４変形例の支持部材６Ｄ（図９参照）と同様に、支持板部６２Ｅから下流方向に折り曲げられた下流側整流板部６７Ｅを有しているものであってもよい。 Fifth Modification
FIG. 10 is an enlarged vertical sectional view showing a fifth modification of the support member for supporting the motor.
As shown in FIG. 10, the supporting member 6E having the upstream side rectifying plate portion 64E is a downstream portion bent in the downstream direction from the supporting plate portion 62E, similarly to the supporting member 6D (see FIG. 9) of the fourth modification. You may have the side rectification board part 67E.

　例えば、図３に示す室外機１は、支持部材６を上下方向に延在するように配置すると共に、前板７２を下側、後板７５を上側、側板７３，７４を横方向に配置して、全体を横向きにしてもよい。 [Other modifications]
As an example of the embodiment of the present invention, as shown in FIG. 1, the upper blowing type (for building) outdoor unit 1 in which the blower 40 and the outlet are disposed above the housing 7 has been described as an example. It is not limited to this. The outdoor unit 1 may be a pre-blowing type (for general household use) in which the blower 40 and the outlet are disposed in the lateral direction. That is, the installation direction of the outdoor unit 1 may be changed as appropriate.
For example, in the outdoor unit 1 shown in FIG. 3, the support member 6 is disposed to extend in the vertical direction, the front plate 72 is disposed at the lower side, the rear plate 75 is disposed at the upper side, and the side plates 73 and 74 are disposed in the lateral direction. The whole may be turned sideways.

For example, the length in the vertical direction of the folded back plate portions 65B and 65F may be longer or shorter than the length in the vertical direction of the upstream side rectifying plate portions 64B and 64F.
　また、図５～図１２に示す支持部材６，６Ａ～６Ｇの基板部６０，６０Ａ～６０Ｇ、上流側整流板部６４Ａ～６４Ｇ、折返板部６５Ｂ，６５Ｆ、及び、下流側整流板部６７Ｄ～６７Ｇは、気流方向（上下方向）に向けて形成した場合を説明したが、気流方向に対して傾斜させて配置してもよい。 In addition, substrate portions 60, 60A to 60G, upstream side rectifying plate portions 64A to 64G, folded plates 65B and 65F, and downstream side rectifying plate portions 67D to 67 shown in FIGS. 5 to 12. Although 67G demonstrated the case where it formed toward the airflow direction (upper and lower direction), you may make it incline with respect to the airflow direction, and may arrange | position it.
　また、図５及び図９に示す対向板部６３，６３Ｄ、図８及び図１２に示す上流側対向板部６６Ｃ，６６Ｇは、気流方向に対して斜めに傾けて配置してもよい。また、その対向板部６３，６３Ｄ、及び、上流側対向板部６６Ｃ，６６Ｇは、先端部を下流方向に対して斜めに折り曲げて形成してもよい。 Further, the opposing plate portions 63 and 63D shown in FIGS. 5 and 9 and the upstream opposing plate portions 66C and 66G shown in FIGS. 8 and 12 may be disposed obliquely with respect to the air flow direction.
