支持板部６２は、モータブラケット５３が載設されて、モータ５を下側から支持する部位であって、支持部材６の上面を形成している。支持板部６２は、基板部６０の下流側から気流の方向（上下方向）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。支持板部６２には、ねじ挿入孔５３ａに合致する位置に、ブラケット固定ねじ５５（図示省略）が螺合する雌ねじが形成されている。
この支持板部６２と対向板部６３は、基板部６０から延出するように折曲形成されているもので、支持部材６の縦断面が略Ｕ字状（略コ字状）に形成されている。なお、支持板部６２、対向板部６３等の延出部位は、溶接等によるものでもよいし、折曲加工との組み合わせでも、その他の手法で形成したものでもよい。 The support plate portion 62 is a portion on which the motor bracket 53 is mounted and supports the motor 5 from below, and forms the upper surface of the support member 6. The support plate portion 62 is arranged so as to extend horizontally from the downstream side of the substrate portion 60 so as to face the direction of the air flow (vertical direction). A female screw to which a bracket fixing screw 55 (not shown) is screwed is formed in the support plate portion 62 at a position matching the screw insertion hole 53a.
The support plate portion 62 and the counter plate portion 63 are bent so as to extend from the substrate portion 60, and the vertical cross section of the support member 6 is formed in a substantially U-shape (a substantially U-shape). ing. The extending portions of the support plate portion 62, the facing plate portion 63, and the like may be formed by welding or the like, may be combined with bending, or may be formed by another method.

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 facing plate portion 63 is a portion where the airflow collides, and forms the lower surface of the support member 6. The facing plate portion 63 is arranged horizontally extending from the upstream side of the substrate portion 60 so as to face the direction of the air flow. The length (extension amount) L1 from the substrate portion 60 to the tip of the counter plate portion 63 (for example, about 22 to 32 mm) is the length (extension amount) L2 from the substrate portion 60 to the tip of the support plate portion 62. It is formed smaller than. In other words, the area of the counter plate portion 63 is smaller than the area of the support plate portion 62. The area can be said to be the front projection area for the air flow.

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。   The lid plate portion 61 is arranged in a plan view so as to be arranged between the support plate portion 62 of the support member 6 bent in a substantially U shape (substantially U shape) and the facing plate portion 63 when viewed from the front. Then, it is composed of a rectangular projecting piece bent and formed into an L shape. A screw insertion hole 61 a into 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 is formed in the central portion of each lid plate portion 61.

≪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。 ≪Action≫
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, in the outdoor unit 1 of the air conditioner, when the motor 5 is rotationally driven, the fan 4 rotates via the motor shaft 51. 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 surfaces on the left and right rear sides, exchanges heat with the heat exchanger 2, and then from the upper opening of the bell mouth / shroud 78. It is sent upward (in the direction of arrow a) and discharged into the atmosphere. Therefore, as shown in FIG. 3, the air (arrow b) sucked into the housing 7 by the fan 4 flows through the heat exchanger 2 and promotes 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に形成された支持部材６は、室外機１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, since air flows from the lower side to the upper side in the housing 7, the support member 6 is arranged so as to face the air flow (air flow).
As shown in FIG. 5, in the support member 6 formed in a U-shape in a vertical cross-section, the area (extension amount) of the facing plate portion 63 facing the airflow in the outdoor unit 1 is the facing plate portion 63. It is formed smaller than the area (extending amount) of the support plate portion 62 arranged on the downstream side. As described above, the support member 6 is formed to have a small area (extension amount) of the surface facing the airflow inside the outdoor unit 1, so that the collision amount of the air that collides with the facing plate portion 63 is reduced. You can

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 side to the upper side so as to hit the support member 6 collides with the facing plate portion 63, is diverted into the left and right directions, and is spread in the left and right directions. It flows in the downstream direction. Therefore, the support member 6 can make the inflow angle of the air flowing in the downstream direction gentle so as to avoid the support plate portion 62.

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 of the support member 6 is formed to be larger than the area of the facing plate portion 63, the motor 5 can be firmly supported. Further, since the support member 6 can flow the air (arrows c and d) in the downstream direction so as to gradually spread in the left-right direction, the air can smoothly flow, and thus the air resistance (coefficient of drag) is reduced. can do. Further, the substrate portion 60, which is formed in the vertical direction, has a function of rectifying the air flow.

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。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。   Since the support member 6 can reduce the air resistance in this manner, the input current of the motor 5 for driving the fan 4 can be reduced and the performance of the fan 4 of the outdoor unit 1 can be improved. Further, since the support member 6 has reduced air resistance, it is possible to reduce noise (sound of wind) generated by the airflow hitting the support member 6.

また、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。   When manufacturing the support member 6, first, a cutting process is performed in which one sheet metal is cut to form the substrate portion 60, the support plate portion 62, the counter plate portion 63, and the lid plate portion 61. Next, a screw forming step of forming a female screw portion (not shown) on the support plate portion 62 and a drilling step of forming a screw insertion hole 61a on the lid plate portion 61 are performed. Subsequently, the supporting member 6 can be completed by performing a bending step of bending the support plate portion 62, the counter plate portion 63, and the lid plate portion 61 on the substrate portion 60 at a right angle.

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 manufactured by press working by cutting and bending one sheet metal. Therefore, the supporting member 6 has a small number of manufacturing steps and a small number of parts, and can be manufactured in a short time, so that the 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 support member 6 formed in this manner is bent in the bending portions 6a and 6b at the downstream end portion and the upstream end portion of the substrate portion 60, and is substantially U-shaped (longitudinal U-shaped) in a vertical cross-sectional view. Due to this, the two ridge lines are formed at the upper and lower ends of the substrate unit 60. Therefore, the support member 6 has an improved support strength with respect to the vertical load, and can secure the strength capable of firmly supporting the blower 40.

Although the present invention has been described above based on the embodiments, the present invention is not limited to the configurations described in the above embodiments, and includes appropriately combining or selecting the configurations described in the embodiments, The configuration can be changed as appropriate without departing from the spirit of the invention.

［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 above-described embodiment has been described by taking the U-shaped support member 6 (see FIG. 5) as an example, the support member 6 is not limited to this. As shown in FIG. 6, the support member 6A has an upstream side flow straightening plate portion 64A that is formed by bending the upstream end of the facing plate portion 63A in the upstream side direction, and has a function of straightening the flow of air. 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 flow straightening plate portion 64A that is formed by bending a bent portion 6Aa formed at the left end portion of the facing plate portion 63A at a right angle to the upstream side direction and extending in the downward direction. The length (extending amount) L3 from the right end to the left end of the facing plate portion 63A is about half the length (extending amount) from the length (extending amount) L2 from the right end to the left end of the support plate portion 62A. To The upstream side current plate portion 64A is arranged in the central portion of the support member 6A when 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。   Therefore, the base plate portion 60A, the support plate portion 62A, the counter plate portion 63A, and the upstream side rectifying plate portion 64A of the support member 6A are arranged inside the range which is imaged as an inverted triangle when viewed from the side. It is arranged so that the airflow flowing downstream is gradually expanded in the lateral direction and the air resistance is reduced.

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 toward the support member 6A formed in this way collides with the tip end surface of the upstream side straightening plate portion 64A and is deflected, and the board portion 60A side (arrow e side) and the support plate portion. The flow is divided into a flow toward the tip side of 62A (arrow f side). The divided air becomes a flow along the upstream flow straightening plate portion 64A extending in the upstream direction to some extent, and flows in the downstream 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 surface of the upstream side straightening vane portion 64A flows at a gentle inflow angle with respect to the support plate portion 62A, and thus flows so as to reduce the amount of collision that collides with the support plate portion 62A. ..

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, f) deflected at the tip end surface of the upstream side straightening vane portion 64A becomes a flow that flows downstream along the substrate portion 60A. Therefore, the amount of air that collides with each surface of the support member 6A (upstream side rectifying plate portion 64A, facing plate portion 63A, substrate portion 60A, and support plate portion 62A) is smaller than that of the supporting member 6 of the embodiment. Since noise and air resistance (coefficient of drag) are small, it is easy for air to flow. As a result, the input current for driving the blower 40 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 Modification]
FIG. 7 is an enlarged vertical cross-sectional view showing a second modification of the support member that supports the motor.
As shown in FIG. 7, the support member 6B is formed so that the upstream end of the upstream flow straightening plate portion 64B is bent in the downstream direction to form an R portion r1 and the R portion r1 is folded in the downstream direction. It may have 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 is a bent portion that is formed by extending the upstream side of the same upstream rectifying plate portion 64B as the upstream rectifying plate portion 64A of the first modified example and folding back 180 degrees downstream. Is. The outer peripheral surface of the R portion r1 is formed in a semicircular shape in a sectional view. The R portion r1 is arranged at the center of the support member 6B when viewed from below. The R portion r1 has the function of smoothing the air flow and the function of improving the strength.
The folding-back plate portion 65B is arranged on the left side of the upstream-side straightening vane plate portion 64B along the upstream-side straightening vane plate portion 64B in parallel with the downstream side direction.

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ｉ）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 toward the supporting member 6B formed in this way collides with the R portion r1 at the upstream end portion, the flow direction is changed, and the air flows along the upstream flow straightening plate portion 64B and the substrate portion 60B. It is dispersed into a flowing flow (arrow i) and a flowing flow (arrow h) along the folding 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 air flow (arrow g) whose flow direction in the R portion r1 is changed to the right side of the support member 6B has a gentle inflow angle with respect to the facing plate portion 63B. Therefore, the amount of collision of air with the facing plate portion 63B is small. The air flow (arrow h) whose flow direction is changed to the left side of the support member 6B at the R portion r1 is a flow from the R portion r1 toward the upper left direction 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）。   Therefore, the collision amount of the air that collides with each surface of the support member 6B is small. As a result, 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 cross-sectional view showing a third modification of the support member that supports the motor.
As shown in FIG. 8, the supporting member 6C may have an upstream facing plate portion 66C formed by bending the upstream end of the upstream flow straightening plate portion 64C along the facing plate portion 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 support member 6C has an upstream facing plate portion 66C formed by bending the bent portion 6Ca at the upstream end of the upstream flow straightening plate portion 64C in a direction facing the air flow direction. .. The upstream side counter plate portion 66C is formed at right angles in the left-right direction with respect to the upstream side straightening plate portion 64C formed in the air flow direction. The upstream facing plate portion 66C is arranged substantially in the center of the support member 6C when viewed from below. The area (extension amount) of the upstream facing plate portion 66C is formed smaller than the area (extension amount) of the facing plate portion 63C. The area (extension amount) of the facing 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 toward the support member 6C formed in a substantially inverted S-shape when viewed from the side collides with the upstream facing plate portion 66C and the flow direction is changed. The deflected air flows toward the facing plate portion 63C and the base plate portion 60C with a gentle inflow angle (arrow i) and the left end of the support plate portion 62C along the upstream side flow straightening plate portion 64C. And the air flow (arrow j) flowing toward the section side. Further, since the supporting member 6C having a substantially inverted S-shape when viewed from the side is formed with many bent portions 6Ca and ridges, it is possible to improve the overall strength.

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 in the upstream facing plate portion 66C is turned to the right side of the support member 6C flows in the downstream direction so as to avoid the support plate portion 62C. The air flow (arrow j) whose flow direction is changed to the left side of the support member 6C in the upstream side facing plate portion 66C has a gentle inflow angle with respect to the facing plate portion 63C, and the flow direction of the facing plate portion 63C is reduced. The amount of air impinging on the lower surface is reduced.

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）。   Therefore, the collision amount of the air that collides with each surface of the support member 6C is small. As a result, the support member 6C also has low 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 Modification]
FIG. 9 is an enlarged vertical cross-sectional view showing a fourth modification of the support member that supports the motor.
As shown in FIG. 9, the support member 6D may have a downstream flow straightening plate portion 67D that 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 flow straightening plate portion 67D that is formed by bending the bent portion 6Da at the left end of the support plate portion 62D to the downstream direction side and extending in the downstream direction. The downstream rectifying plate portion 67D is formed in an upward direction at a right angle to the support plate portion 62D formed in a direction (horizontal direction) orthogonal to the air flow direction. The downstream side current plate 67D is arranged 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）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 toward the supporting member 6D formed in this way collides with the facing plate portion 63D and the flowing direction is changed to the left and right (arrows k and m). The air (arrow k) flowing to the right of the facing plate portion 63D flows in the downstream direction along the substrate portion 60D. The air (arrow m) that has flowed to the left side of the facing plate portion 63D flows downstream so as to avoid the support plate portion 62D, is rectified on the left side surface of the downstream rectifying plate portion 67D, and along the downstream rectifying plate portion 67D. Flows to the downstream side.

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）。   Therefore, the collision amount of the air that collides with each surface of the support member 6D is small. The support member 6D can reduce the air resistance by rectifying the downstream side, so that 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 cross-sectional view showing a fifth modification of the support member that supports the motor.
As shown in FIG. 10, the support member 6E having the upstream side flow straightening plate portion 64E has a downstream end bent from the support plate portion 62E in the downstream direction, like the support member 6D of the fourth modification (see FIG. 9). It may have the side current plate 67E.

この場合、支持部材６Ｅは、第１変形例の支持部材６Ａ（図６参照）と同様に、基板部６０Ｅと、支持板部６２Ｅと、対向板部６３Ｅと、上流側整流板部６４Ｅと、を有すると共に、さらに、支持板部６２Ｅから下流方向に延びる下流側整流板部６７Ｅを有している。また、上下方向に向けて形成されている基板部６０Ｅ、上流側整流板部６４Ｅ、及び、下流側整流板部６７Ｅは、空気が下流方向に真っすぐに流れるようにする整流機能がある。   In this case, the support member 6E is similar to the support member 6A of the first modification (see FIG. 6), the substrate portion 60E, the support plate portion 62E, the counter plate portion 63E, the upstream side current plate portion 64E, And further has a downstream side current plate 67E extending in the downstream direction from the support plate 62E. Further, the board portion 60E, the upstream side flow straightening plate portion 64E, and the downstream side flow straightening plate portion 67E that are formed in the vertical direction have a flow regulating function that allows air to flow straight in the downstream direction.

このように支持部材６Ｅは、支持板部６２Ｅの曲げ部６Ｅａを直角に曲げて下流方向に延びている下流側整流板部６７Ｅを有していることによって、第４変形例と同様に、下流側の空気の流れを整流させて、空気抵抗を小さくすることができる。   As described above, the support member 6E has the downstream side rectifying plate portion 67E that bends the bent portion 6Ea of the support plate portion 62E at a right angle and extends in the downstream direction. The air resistance can be reduced by rectifying the side air flow.

［第６変形例］
図１１は、モータを支持する支持部材の第６変形例を示す拡大縦断面図である。
また、図１１に示すように、第２変形例（図７参照）のような折返板部６５Ｆを有する支持部材６Ｆは、第４変形例の支持部材６Ｄ（図９参照）と同様に、支持板部６２Ｆから下流方向に折り曲げられた下流側整流板部６７Ｆを有するものであってもよい。 [Sixth Modification]
FIG. 11 is an enlarged vertical cross-sectional view showing a sixth modification of the support member that supports the motor.
Further, as shown in FIG. 11, the support member 6F having the folded plate portion 65F as in the second modification (see FIG. 7) is supported similarly to the support member 6D (see FIG. 9) in the fourth modification. It may have a downstream side current plate 67F that is bent in the downstream direction from the plate 62F.

このように形成すれば支持部材６Ｆは、下流側整流板部６７Ｆを有していることによって、第４変形例と同様に、下流側の空気の流れを整流させて、空気抵抗を小さくすることができる。   If formed in this way, the support member 6F has the downstream side flow regulating plate portion 67F, so that the flow of air on the downstream side is regulated and the air resistance is reduced, as in the fourth modification. You can

［第７変形例］
図１２は、モータを支持する支持部材の第７変形例を示す拡大縦断面図である。
また、図１２に示すように、第３変形例（図８参照）のような上流側対向板部６６Ｇを有する支持部材６Ｇも、第４変形例の支持部材６Ｄ（図９参照）と同様に、支持板部６２Ｇから下流方向に折り曲げられた下流側整流板部６７Ｇを有するものであってもよい。 [Seventh Modification]
FIG. 12 is an enlarged vertical cross-sectional view showing a seventh modification of the support member that supports the motor.
Further, as shown in FIG. 12, a support member 6G having an upstream facing plate portion 66G as in the third modification (see FIG. 8) is similar to the support member 6D of the fourth modification (see FIG. 9). It may have a downstream side current plate 67G that is bent in the downstream direction from the support plate 62G.

このように形成すれば支持部材６Ｇは、下流側整流板部６７Ｇを有していることによって、第４変形例と同様に、下流側の空気の流れを整流させて、空気抵抗を小さくすることができる。   If formed in this way, the supporting member 6G has the downstream side flow regulating plate portion 67G, so that the downstream side air flow is regulated and the air resistance is reduced, as in the fourth modification. You can

［その他の変形例］
本発明の実施形態の一例として、図１に示すように、送風機４０及び吹き出し口を筐体７の上側に配置した上吹きタイプ（ビル用）の室外機１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。室外機１は、送風機４０及び吹き出し口を横方向に配置した前吹きタイプ（一般家庭用）であってもよい。つまり、室外機１の設置方向は、適宜変更しても構わない。
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 above-mentioned blower type (for building) outdoor unit 1 in which the blower 40 and the blowout port are arranged on the upper side of the housing 7 has been described as an example. It is not limited to this. The outdoor unit 1 may be a front blowing type (for general household use) in which the blower 40 and the blowout port are arranged in the lateral direction. That is, the installation direction of the outdoor unit 1 may be changed appropriately.
For example, in the outdoor unit 1 shown in FIG. 3, the support member 6 is arranged so as to extend in the vertical direction, the front plate 72 is arranged on the lower side, the rear plate 75 is arranged on the upper side, and the side plates 73, 74 are arranged in the lateral direction. Then, the whole may be turned sideways.

支持部材６の一例として、図４に示すように、前後方向に真っすぐに延びる水平なものを例に挙げて説明したが、支持部材６は、例えば、側面視して略Ｊ字状や、略く字状に曲がっている部材であっても構わない。   As an example of the support member 6, the horizontal member that extends straight in the front-rear direction has been described as an example as shown in FIG. It may be a member bent in a V shape.

また、支持部材６の一例として、図４及び図５に示すように、基板部６０の高さが均一な帯状に形成されたものを例に挙げて説明したが、これに限定されない。支持部材６は、例えば、基板部６０の前後の両端部側の高さを高くして、モータブラケット５３が載設される中央部位の高さを低くしたものであってもよい。   In addition, as an example of the support member 6, as shown in FIGS. 4 and 5, the base member 60 having the uniform height formed in the shape of a strip has been described, but the support member 6 is not limited thereto. The support member 6 may be, for example, one in which the heights of the front and rear end portions of the substrate 60 are increased and the height of the central portion on which the motor bracket 53 is mounted is lowered.

また、前記実施形態では、縦断面視してコ字形状の支持部材６（図５参照）を例に挙げて説明したが、支持部材６は、縦断面視して略Ｈ形状の押出成形して形成された一部材であってもよい。
この場合、支持部材６は、水平方向に配置された支持板部６２と、支持板部６２よりも短く形成されて水平に配置された対向板部６３と、支持板部６２と対向板部６３との間に架設された基板部６０と、を一体に形成する。
このように支持部材６を縦断面視して略Ｈ形状に形成しても、対向板部６３の面積が支持板部６２の面積よりも小さいため、空気抵抗を小さくすることができる。 In addition, in the above-described embodiment, the support member 6 (see FIG. 5) having a U-shape in a vertical cross-section is described as an example, but the support member 6 is extrusion-molded in a substantially H-shape in a vertical cross-section. It may be one member formed by
In this case, the support member 6 includes a support plate portion 62 arranged in the horizontal direction, an opposed plate portion 63 formed shorter than the support plate portion 62 and arranged horizontally, the support plate portion 62 and the opposed plate portion 63. And a substrate portion 60 that is erected between and.
Even when the support member 6 is formed in a substantially H shape in a vertical cross-section as described above, the air resistance can be reduced because the area of the facing plate portion 63 is smaller than the area of the support plate portion 62.

また、支持部材６の基板部６０は、前後方向に延びる縦断面視して凹形状の溝部、または、凸部を形成して補強してもよい。   Further, the substrate portion 60 of the supporting member 6 may be reinforced by forming a groove portion or a convex portion having a concave shape when viewed in a longitudinal section extending in the front-rear direction.

また、図７及び図１１に示す折返板部６５Ｂ，６５Ｆの上下方向の長さは、上流側整流板部６４Ｂ，６４Ｆの上下方向の長さと同一にした場合を例に挙げて説明したが、適宜変更しても構わない。例えば、折返板部６５Ｂ，６５Ｆの上下方向の長さは、上流側整流板部６４Ｂ，６４Ｆの上下方向の長さよりも長くしても、短く形成してもよい。   The vertical lengths of the folding plate portions 65B and 65F shown in FIGS. 7 and 11 are the same as the vertical lengths of the upstream flow straightening plate portions 64B and 64F, but the vertical lengths have been described as an example. You may change it suitably. For example, the vertical lengths of the folding plate portions 65B and 65F may be longer or shorter than the vertical lengths of the upstream flow straightening 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, the substrate parts 60, 60A to 60G of the support members 6, 6A to 6G shown in FIGS. 5 to 12, the upstream side straightening plate parts 64A to 64G, the folding plate parts 65B and 65F, and the downstream side straightening plate parts 67D to. Although 67G has been described as being formed in the airflow direction (vertical direction), it may be arranged to be inclined with respect to the airflow direction.

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 facing plate portions 63 and 63D shown in FIGS. 5 and 9 and the upstream side facing plate portions 66C and 66G shown in FIGS. 8 and 12 may be arranged obliquely with respect to the air flow direction. Further, the facing plate portions 63, 63D and the upstream side facing plate portions 66C, 66G may be formed by bending the tip end portion obliquely with respect to the downstream direction.
