上記の構成により、空気調和機の室外機１は、例えば冷房運転時に、熱交換器４の伝熱管４ｂの内部を流通する高温・高圧の冷媒の熱を、伝熱管４ｂに圧接されているフィン４ａに伝熱するとともに、この伝熱されたフィン３ａが、送風ファン３０により背面吸込口１ｃから吸い込まれた空気によって冷却されることで熱交換されるものである。   With the above-described configuration, the outdoor unit 1 of the air conditioner is, for example, a fin that is in pressure contact with the heat of the high-temperature and high-pressure refrigerant that circulates inside the heat transfer tube 4b of the heat exchanger 4 during cooling operation. While transferring heat to 4a, the heat-transferred fin 3a is heat-exchanged by being cooled by the air sucked from the rear suction port 1c by the blower fan 30.

モータ支持体５は、図４に示すように、モータ３１を固定するモータ取付台６と、モータ取付台６の上端を係止して、上熱交換器４０の上端に掛け止めされる上部支持具７と、モータ取付板６の下端を係止して、底板１５上に固定される下部支持具８とからなる。
尚ここでは、モータ支持体５は、モータ取付台６と上部支持具７と下部支持具８との別々の部品構成で説明するが、モータ取付台に上部支持部と下部支持部を備えた一体の構成、または、モータ取付台に上部支持部と下部支持部のいずれかを一体にした構成でも同じ効果を有する。 As shown in FIG. 4, the motor support 5 includes a motor mount 6 that fixes the motor 31 and an upper support that is locked to the upper end of the upper heat exchanger 40 by locking the upper end of the motor mount 6.

The same effect can be obtained with the above-described configuration or a configuration in which either the upper support portion or the lower support portion is integrated with the motor mount.

上部支持具７は、水平状の上面部７０と、この上面部７０の四側から垂下されたフランジ部７１からなり、上面部７０の一部を切り抜き、下方に折り曲げた係止爪７２が、後述するモータ取付台６のフランジ部６１の係止孔６１ａに係止して、その後フランジ部７１とフランジ部６１の側面をネジ止めすることで、モータ取付台６に固定される。
フランジ部７１の側面部は一部が切欠され、上熱交換器４０の上端を挿通する切欠部７３となり、上熱交換器４０に掛け止めされる。
フランジ部７１の前面部７１ａは前面パネル１０の上端とネジ止めされ、さらに前面パネル１０が天板１６とネジ止めされ、フランジ部７１の後面部７１ｂは天板１６とネジ止めされることで、モータ支持体５の上部と上熱交換器４０は天板１６に矜持されることになり、位置ずれが起こることがなくなる。 The upper support 7 is composed of a horizontal upper surface portion 70 and a flange portion 71 suspended from the four sides of the upper surface portion 70, and a locking claw 72 cut out from a part of the upper surface portion 70 and bent downward is provided. The motor mounting base 6 is fixed to the motor mounting base 6 by engaging with a locking hole 61a of the flange part 61 of the motor mounting base 6 to be described later and then screwing the flange part 71 and the side surface of the flange part 61 with screws.
A part of the side surface portion of the flange portion 71 is notched and becomes a notched portion 73 that is inserted through the upper end of the upper heat exchanger 40 and is latched to the upper heat exchanger 40.
The front portion 71a of the flange portion 71 is screwed to the upper end of the front panel 10, the front panel 10 is screwed to the top plate 16, and the rear surface portion 71b of the flange portion 71 is screwed to the top plate 16.

下部支持具８は、水平状の底面８０と、この底面８０の両側面から立ちあがったフランジ部８１と、このフランジ部８１と底面８０の折曲部に設けた係止孔８２とからなり、係止孔８２に後述するモータ取付台のフランジ部６１の下端から突出する係止爪６１ｂを係止し、その後フランジ部８１とフランジ部６１の側面をネジ止めすることで、モータ取付台６を固定し、底面８１と底板１５をネジ止めすることで、モータ支持体５が、室外機１の筺体に固定される。   The lower support 8 includes a horizontal bottom surface 80, a flange portion 81 raised from both side surfaces of the bottom surface 80, and a locking hole 82 provided in a bent portion of the flange portion 81 and the bottom surface 80. The locking claw 61b protruding from the lower end of the flange portion 61 of the motor mount, which will be described later, is locked in the stop hole 82, and then the side of the flange portion 81 and the flange portion 61 is screwed to fix the motor mount 6 The motor support 5 is fixed to the housing of the outdoor unit 1 by screwing the bottom surface 81 and the bottom plate 15 with screws.

モータ取付台６は、図５に示すように、１枚の鋼板から切抜き折り曲げ加工をして成形される。加工されたモータ取付台６は、図４に示すように、熱交換器４と略同じ高さになり、モータ取付面６０と、鋼板の周囲を背面側に折り曲げたフランジ部６１とからなる。フランジ部６１の上面側には前述した上部支持具７の係止爪７２を係止する係止孔６１ａが備えられ、フランジ部６１の両側面下端には前述した下部支持具８の係止孔８２に係止するための係止爪６１ｂが突出状に備えられている。   As shown in FIG. 5, the motor mount 6 is formed by cutting and bending from a single steel plate. As shown in FIG. 4, the processed motor mounting base 6 has substantially the same height as the heat exchanger 4, and includes a motor mounting surface 60 and a flange portion 61 where the periphery of the steel plate is bent to the back side. A locking hole 61 a for locking the locking claw 72 of the upper support 7 described above is provided on the upper surface side of the flange portion 61, and the locking holes of the lower support 8 described above are provided at the lower ends of both side surfaces of the flange portion 61. A locking claw 61b for locking to 82 is provided in a protruding shape.

モータ取付面６０には、図４から図６に示すように、モータ３１に抜き形状を合わせたモータ取付口６２が上下に２箇所設けられる。
尚、モータ３１は、軸３１ａの対面側の底部をモータ取付口６２に嵌め込み、モータ３１の側面複数個所に設けた取付部３１ｂとモータ取付口６２の周囲にあるネジ孔６２ａとをネジ止めすることで固定される。
その後に、固定されたモータ３１の軸３１ａに送風ファン３０を軸支することで、送風ファン３０は室外機１に設置され、モータ３１により回転可能となる。 As shown in FIGS. 4 to 6, the motor mounting surface 60 is provided with two motor mounting ports 62, which are formed in the same shape as the motor 31 in the vertical direction.
In addition, the motor 31 fits the bottom part of the opposite side of the shaft 31 a into the motor attachment port 62, and screws the attachment parts 31 b provided at a plurality of positions on the side surface of the motor 31 and the screw holes 62 a around the motor attachment hole 62. It is fixed by that.
Thereafter, the blower fan 30 is pivotally supported on the shaft 31 a of the fixed motor 31, so that the blower fan 30 is installed in the outdoor unit 1 and can be rotated by the motor 31.

モータ取付台６は、熱交換器４と送風ファン３０の間に配置されることで、通風の抵抗となるため、モータ取付面６０の鋼板が占める面積を少なくした方が良い。一方、鋼板が占める面積を少なくすると送風ファン３０とモータ３１を支持する強度が損なわれ、特に送風ファン３０の回転時の振動による、ねじれ方向に弱くなる虞がある。
そこで、モータ取付面６０には、図５、図６に示すように、モータ取付口６２の他に、通風のために複数箇所の開口部６３を備える。開口部６３は、鋼板から開口部の周囲に設ける開口部フランジ６３１となる部分を残して切り抜き、図５の一点鎖線で示す部分を背面側に折り曲げて成形される。開口部６３は、モータ取付台６の上部側に四角形状の抜き孔による上部四角形開口部６３aと、モータ取付口６２、６２の間で、Ｘ字状の筋交いに鋼板を残すことで形成された三角形の抜き孔による三角形開口部６３ｂと、三角形開口部６３ｂの下で四角形の抜き孔にＹ字状に筋交いに鋼板を残すことで形成されたＹ字状の上にあたるベース形開口部６３ｃと、Ｙ字状の下にあたる台形開口部６３ｄと、モータ取付台６の下部側の下部四角形開口部６３ｅがある。
複数箇所の開口部６３により通風の抵抗となる面を少なくするとともに、鋼板を筋交いに残すことで梁構造とし、ねじりの変形に強くなり、強度が向上するものとなる。 Since the motor mount 6 is arranged between the heat exchanger 4 and the blower fan 30 and becomes resistance to ventilation, it is better to reduce the area occupied by the steel plate of the motor mount surface 60. On the other hand, when the area occupied by the steel plate is reduced, the strength for supporting the blower fan 30 and the motor 31 is impaired, and in particular, the twisting direction due to vibration during rotation of the blower fan 30 may be weakened.
Therefore, as shown in FIGS. 5 and 6, the motor mounting surface 60 includes a plurality of openings 63 for ventilation in addition to the motor mounting port 62. The opening 63 is formed by cutting out from the steel sheet, leaving a portion to be the opening flange 631 provided around the opening, and bending the portion indicated by the one-dot chain line in FIG. 5 to the back side. The opening 63 is formed by leaving a steel plate in the X-shaped bracing between the upper rectangular opening 63a formed by a rectangular hole on the upper side of the motor mounting base 6 and the motor mounting ports 62 and 62.

The pressing portion 64a is positioned at the contact portion 44 between the upper heat exchanger 40 and the lower heat exchanger 41, and the upper heat exchanger 40 and the lower heat exchanger 41 are not displaced so as not to be displaced during the transfer. It plays the role which presses both the heat exchanger 40 and the lower heat exchanger 41 to the back side.

下熱交換器支持部６５は、下部四角形開口部６３ｅの抜き孔となる部分を利用して一体に切り抜かれ、下部四角形開口部６３ｅの下端から背面側に突出し、先端が上方に折れ曲がり、折れ曲がった部分が下熱交換器４１の押圧部６５ａとなる。押圧部６５ａは、下熱交換器４１を背面側に押圧する。   The lower heat exchanger support 65 is cut out integrally using a portion that becomes a hole of the lower square opening 63e, protrudes from the lower end of the lower square opening 63e to the back side, and the tip is bent upward and bent. The portion becomes the pressing portion 65 a of the lower heat exchanger 41. The pressing part 65a presses the lower heat exchanger 41 to the back side.
