　従来の空気調和機の室外機として、筐体内において送風装置の位置を移動可能な構成とした室外機も知られている。例えば、特許文献１に記載の空気調和機の室外機は、送風装置のメンテナンスを目的として、筐体内において送風装置の位置を移動可能な構成としている。この特許文献１に記載の空気調和機の室外機は、熱交換器の前方に送風装置が配置されている。この送風装置は、縦支持部材及び横支持部材を備えた固定機構により、筐体に固定されている。 As an outdoor unit of a conventional air conditioner, an outdoor unit having a configuration in which the position of a blower can be moved within a housing is also known. For example, the outdoor unit of an air conditioner described in Patent Document 1 has a configuration in which the position of the blower can be moved within the housing for the purpose of maintenance of the blower. In the outdoor unit for an air conditioner described in Patent Document 1, a blower is disposed in front of the heat exchanger. This blower is fixed to the housing by a fixing mechanism including a vertical support member and a horizontal support member.
　縦支持部材は、ネジ止めにより筐体に固定されている。そして、縦支持部材と筐体とを固定している雄ネジを緩めると、縦支持部材は、下端部を中心として、上端部が前後方向に揺動自在となる。横支持部材には、送風装置が取り付けられている。より詳しくは、横支持部材には、送風装置のファンモータが取り付けられている。この横支持部材は、前後方向に延びる複数の脚材を備えている。脚材のそれぞれには、前後方向に延びる長穴が形成されている。そして、脚材のそれぞれの長穴に挿入された雄ネジが縦支持部材の雌ネジにねじ込まれることにより、縦支持部材と雄ネジの頭部との間に脚材が挟持され、横支持部材が縦支持部材に固定される。換言すると、脚材のそれぞれの長穴に挿入された雄ネジが縦支持部材の雌ネジにねじ込まれることにより、横支持部材に取り付けられた送風装置が所定の位置に固定される。 The vertical support member is fixed to the housing by screws. When the male screw that fixes the vertical support member and the housing is loosened, the vertical support member can swing in the front-rear direction about the lower end. A blower is attached to the lateral support member. More specifically, a fan motor of a blower is attached to the lateral support member. The lateral support member includes a plurality of legs that extend in the front-rear direction. Each leg is formed with a long hole extending in the front-rear direction. Then, the male screw inserted into each elongated hole of the leg member is screwed into the female screw of the vertical support member, so that the leg member is sandwiched between the vertical support member and the head of the male screw, and the horizontal support member Is fixed to the vertical support member. In other words, when the male screw inserted into each elongated hole of the leg member is screwed into the female screw of the vertical support member, the blower attached to the horizontal support member is fixed at a predetermined position.
　特許文献１に記載の空気調和機の室外機において送風装置のメンテナンスを行う場合、まず、横支持部材と縦支持部材とを固定している雄ネジを緩める。これにより、送風装置が固定された横支持部材は、該横支持部材の脚材に形成された長穴の長手方向に沿って、移動自在となる。すなわち、送風装置が固定された横支持部材は、前後方向に移動自在になる。その後、縦支持部材と筐体とを固定している雄ネジを緩め、縦支持部材を後方へ倒すことにより、送風装置のプロペラファンが、該プロペラファンの外周を囲っていたベルマウスから抜け出る。これにより、送風装置のメンテナンスが可能となる。 When performing maintenance of the blower in the outdoor unit of an air conditioner described in Patent Document 1, first, the male screw that fixes the horizontal support member and the vertical support member is loosened. Thereby, the horizontal support member to which the air blower is fixed becomes movable along the longitudinal direction of the long hole formed in the leg member of the horizontal support member. That is, the lateral support member to which the blower is fixed is movable in the front-rear direction. Thereafter, the male screw fixing the vertical support member and the casing is loosened, and the vertical support member is tilted backward, so that the propeller fan of the blower comes out of the bell mouth surrounding the outer periphery of the propeller fan. Thereby, maintenance of an air blower is attained.

Each of the motor mounting portion 51 and the pair of leg portions 55 is manufactured as a separate part, and each of the motor mounting portion 51 and the pair of leg portions 55 is connected by screwing or welding to manufacture the motor support portion 50. Of course.
　室外機１００を正面側から見た際、一対の脚部５５のうちで右側に位置する脚部５５は、右側の支柱４１ａの右側面部と対向する。この脚部５５は、複数の開口部５６を備えている。これら開口部５６には、右側の支柱４１ａのネジ固定部４２にねじ込まれる雄ネジ４５が挿入される。このため、開口部５６の数は右側の支柱４１ａのネジ固定部４２と同数となり、開口部５６の位置は、右側の支柱４１ａのネジ固定部４２と対向する位置に設けられる。したがって、本実施の形態では、室外機１００を正面側から見た際、一対の脚部５５のうちで右側に位置する脚部５５には、上下方向に間隔を空けて、２つの開口部５６が設けられている。以下、室外機１００を正面側から見た際に一対の脚部５５のうちで右側に位置する脚部５５を、右側の脚部５５と称することとする。 When the outdoor unit 100 is viewed from the front side, the leg portion 55 located on the right side of the pair of leg portions 55 faces the right side surface portion of the right column 41a. The leg portion 55 includes a plurality of openings 56. A male screw 45 to be screwed into the screw fixing portion 42 of the right column 41a is inserted into these openings 56. Therefore, the number of openings 56 is the same as that of the screw fixing portions 42 of the right column 41a, and the position of the openings 56 is provided at a position facing the screw fixing portions 42 of the right column 41a. Therefore, in the present embodiment, when the outdoor unit 100 is viewed from the front side, the leg 55 located on the right side of the pair of legs 55 is spaced apart in the vertical direction from the two openings 56. Is provided. Hereinafter, when the outdoor unit 100 is viewed from the front side, the leg part 55 located on the right side of the pair of leg parts 55 is referred to as a right leg part 55.
　開口部５６は、前後方向に延びる長穴部５７と、長穴部５７から上方に切り欠かれた凹部５８と、を備えている。凹部５８の位置は、送風装置３０が正規の位置となった際に、雄ネジ４５が挿入される位置となっている。すなわち、凹部５８の位置は、送風装置３０が所望の位置となった際に、雄ネジ４５が挿入される位置となっている。換言すると、送風装置３０が正規の位置となった状態でモータ支持部５０が基部４１に固定された際、凹部５８に雄ネジ４５が挿入された状態となる。なお、送風装置３０の正規の位置とは、送風装置３０と熱交換器２０との間の距離が室外機１００の運転時に所望される距離となっており、送風装置３０の角度が室外機１００の運転時に所望される角度となっている位置である。 The opening 56 includes a long hole portion 57 extending in the front-rear direction and a concave portion 58 cut out upward from the long hole portion 57. The position of the concave portion 58 is a position where the male screw 45 is inserted when the blower device 30 is in the normal position. That is, the position of the recess 58 is a position where the male screw 45 is inserted when the blower device 30 reaches a desired position. In other words, when the motor support 50 is fixed to the base 41 with the blower 30 in the normal position, the male screw 45 is inserted into the recess 58. In addition, the normal position of the air blower 30 is a distance desired between the air blower 30 and the heat exchanger 20 when the outdoor unit 100 is operated, and the angle of the air blower 30 is the outdoor unit 100. It is the position which becomes the angle desired at the time of driving | operation.
　凹部５８の縁は、例えば、円弧形状となっている。また例えば、凹部５８の縁は、上方向に延びる長穴形状であってもよい。すなわち、凹部５８の縁の形状は、長穴部５７に雄ネジ４５が挿入されている状態において長穴部５７と雄ネジ４５との間に形成される前後方向の隙間に対して、凹部５８に雄ネジ４５が挿入されている状態において凹部５８と雄ネジ４５との間に形成される前後方向の隙間が小さくなる形状であればよい。 The edge of the recess 58 has, for example, an arc shape. Further, for example, the edge of the recess 58 may have a long hole shape extending upward. That is, the shape of the edge of the concave portion 58 is such that the concave portion 58 is in the front-rear direction gap formed between the long hole portion 57 and the male screw 45 when the male screw 45 is inserted into the long hole portion 57. In the state in which the male screw 45 is inserted, the gap in the front-rear direction formed between the recess 58 and the male screw 45 may be reduced.
　ここで、後述のように、筐体１に設けられる熱交換器２０は、熱交換部２１が前後方向に２つ並設される場合と、熱交換部２１が前後方向に３つ並設される場合とがある。すなわち、本実施の形態に係る室外機１００では、並設される熱交換部２１の数に応じて、送風装置３０の正規の位置が２つ存在することとなる。このため、開口部５６は、送風装置３０の正規の位置に応じて、２つの凹部５８を備えている。これらの凹部５８は、前後方向に規定間隔Ｌを空けて設けられている。すなわち、開口部５６は、前後方向に規定間隔Ｌを空けて、２つの凹部５８を備えている。なお、図１１で後述するように、熱交換部２１の前後方向の厚みは、厚みＴとなっている。そして、規定間隔Ｌは、厚みＴと同じ値となっている。 Here, as will be described later, in the heat exchanger 20 provided in the housing 1, two heat exchange portions 21 are arranged in the front-rear direction and three heat exchange portions 21 are arranged in the front-rear direction. There is a case. That is, in the outdoor unit 100 according to the present embodiment, there are two regular positions of the blower device 30 according to the number of heat exchange units 21 arranged in parallel. For this reason, the opening part 56 is provided with two recessed parts 58 according to the regular position of the air blower 30. FIG. These recesses 58 are provided with a specified interval L in the front-rear direction. That is, the opening 56 includes two recesses 58 with a specified interval L in the front-rear direction. As will be described later with reference to FIG. 11, the thickness of the heat exchanging portion 21 in the front-rear direction is a thickness T. The specified interval L is the same value as the thickness T.
　さらに、右側の脚部５５には、貫通孔５９が形成されている。貫通孔５９の位置は、送風装置３０が正規の位置となった際に、右側の支柱４１ａの凸部４３が挿入される位置となっている。換言すると、貫通孔５９の位置は、雄ネジ４５のそれぞれが開口部５６の凹部５８に挿入された状態において、凸部４３が挿入される位置となっている。ここで、上述のように、本実施の形態に係る室外機１００では、並設される熱交換部２１の数に応じて、送風装置３０の正規の位置が２つ存在することとなる。このため、右側の脚部５５は、送風装置３０の正規の位置に応じて、２つの貫通孔５９を備えている。これらの貫通孔５９は、前後方向に規定間隔Ｌを空けて形成されている。 Furthermore, a through hole 59 is formed in the right leg 55. The position of the through hole 59 is a position where the convex portion 43 of the right column 41a is inserted when the blower 30 is in the normal position. In other words, the position of the through hole 59 is a position where the convex portion 43 is inserted in a state where each of the male screws 45 is inserted into the concave portion 58 of the opening portion 56. Here, as described above, in the outdoor unit 100 according to the present embodiment, there are two regular positions of the blower device 30 according to the number of the heat exchange units 21 arranged in parallel. For this reason, the right leg 55 includes two through holes 59 according to the normal position of the blower 30. These through holes 59 are formed with a specified interval L in the front-rear direction.
　室外機１００を正面側から見た際、一対の脚部５５のうちで左側に位置する脚部５５は、右側の脚部５５を左右反転させた構成となっている。以下、室外機１００を正面側から見た際に一対の脚部５５のうちで左側に位置する脚部５５を、左側の脚部５５と称することとする。 When the outdoor unit 100 is viewed from the front side, the leg portion 55 located on the left side of the pair of leg portions 55 has a configuration in which the right leg portion 55 is reversed left and right. Hereinafter, when the outdoor unit 100 is viewed from the front side, the leg part 55 located on the left side of the pair of leg parts 55 is referred to as a left leg part 55.
　すなわち、左側の脚部５５は、左側の支柱４１ａの左側面部と対向する。左側の脚部５５には、左側の支柱４１ａのネジ固定部４２と対向する位置のそれぞれに、上述の構成の開口部５６を備えている。また、左側の脚部５５には、送風装置３０が正規の位置となった際に左側の支柱４１ａの凸部４３が挿入される位置に、２つの貫通孔５９が形成されている。 That is, the left leg 55 opposes the left side of the left column 41a. The left leg 55 is provided with the opening 56 having the above-described configuration at each position facing the screw fixing portion 42 of the left column 41a. Further, the left leg portion 55 is formed with two through holes 59 at a position where the convex portion 43 of the left column 41a is inserted when the blower device 30 is in the normal position.
　続いて、基部４１に対するモータ支持部５０の取付方法について説明する。 Subsequently, a method for attaching the motor support 50 to the base 41 will be described.
　図８は、本発明の実施の形態に係る空気調和機の室外機において、室外機の前方から固定機構を見た分解斜視図である。図９は、本発明の実施の形態に係る空気調和機の室外機において、２つ熱交換部が前後方向に並設された熱交換器に対して送風装置が正規の位置に固定された状態を示す側面図である。図１０は、図９のＣ部拡大図である。図１１は、本発明の実施の形態に係る空気調和機の室外機において、３つ熱交換部が前後方向に並設された熱交換器に対して送風装置が正規の位置に固定された状態を示す側面図である。図１２は、図１１のＤ部拡大図である。また、図１３は、本発明の実施の形態に係る空気調和機の室外機において、送風装置が正規でない位置に配置された状態を示す側面図である。なお、図９～図１３では、紙面左側が室外機１００の正面側つまり前面側となっている。 FIG. 8 is an exploded perspective view of the fixing mechanism viewed from the front of the outdoor unit in the outdoor unit of the air conditioner according to the embodiment of the present invention. FIG. 9 shows a state in which the air blower is fixed at a normal position with respect to the heat exchanger in which two heat exchange portions are arranged in the front-rear direction in the outdoor unit of the air conditioner according to the embodiment of the present invention. FIG. FIG. 10 is an enlarged view of a portion C in FIG. FIG. 11 shows a state in which the air blower is fixed at a normal position with respect to the heat exchanger in which the three heat exchanging portions are arranged in the front-rear direction in the outdoor unit of the air conditioner according to the embodiment of the present invention. FIG. FIG. 12 is an enlarged view of a portion D in FIG. FIG. 13 is a side view showing a state in which the blower is disposed at a non-regular position in the outdoor unit of the air conditioner according to the embodiment of the present invention. 9 to 13, the left side of the drawing is the front side of the outdoor unit 100, that is, the front side.
　基部４１にモータ支持部５０を固定する際、まず、送風装置３０のファンモータ３２をモータ支持部５０のモータ取付部５１に取り付ける。その後、モータ支持部５０の脚部５５に設けられた開口部５６のそれぞれに、雄ネジ４５を挿入する。そして、開口部５６に挿入された雄ネジ４５のそれぞれを、基部４１のネジ固定部４２にねじ込む。雄ネジ４５のそれぞれがネジ固定部４２に完全にねじ込まれていない場合、開口部５６の長穴部５７に雄ネジ４５を通過させることにより、送風装置３０及びモータ支持部５０を筐体１内において前後方向に移動させることができる。すなわち、雄ネジ４５のそれぞれが緩んでいる場合、開口部５６の長穴部５７に雄ネジ４５を通過させることにより、送風装置３０及びモータ支持部５０を筐体１内において前後方向に移動させることができる。 When fixing the motor support 50 to the base 41, first, the fan motor 32 of the blower 30 is attached to the motor attachment 51 of the motor support 50. Thereafter, the male screw 45 is inserted into each of the openings 56 provided in the leg portion 55 of the motor support portion 50. Then, each of the male screws 45 inserted into the opening portion 56 is screwed into the screw fixing portion 42 of the base portion 41. When each of the male screws 45 is not completely screwed into the screw fixing portion 42, the male screw 45 is passed through the elongated hole portion 57 of the opening portion 56, so that the blower 30 and the motor support portion 50 are placed inside the housing 1. Can be moved back and forth. That is, when each of the male screws 45 is loose, the blower 30 and the motor support portion 50 are moved in the front-rear direction in the housing 1 by passing the male screw 45 through the elongated hole portion 57 of the opening 56. be able to.
　熱交換部２１が前後方向に２つ並設された熱交換器２０が筐体１に設けられる場合、送風装置３０及びモータ支持部５０を後方へ移動させる。送風装置３０及びモータ支持部５０を後方へ移動させていくと、雄ネジ４５のそれぞれが、開口部５６における前側の凹部５８の下方に位置することとなる。この状態になると、図９及び図１０に示すように、送風装置３０及びモータ支持部５０の重みによってモータ支持部５０が下方へ落下し、雄ネジ４５のそれぞれが、開口部５６における前側の凹部５８に挿入される。 When the heat exchanger 20 in which two heat exchanging portions 21 are arranged in the front-rear direction is provided in the housing 1, the blower 30 and the motor support portion 50 are moved rearward. When the blower 30 and the motor support portion 50 are moved rearward, each of the male screws 45 is positioned below the front concave portion 58 in the opening 56. In this state, as shown in FIGS. 9 and 10, the motor support 50 falls downward due to the weight of the blower 30 and the motor support 50, and each of the male screws 45 is a front recess in the opening 56. 58 is inserted.
　この状態では、送風装置３０及びモータ支持部５０を側面視した場合、送風装置３０及びモータ支持部５０は、送風装置３０の重みにより、雄ネジ４５のいずれか１つの位置を回転中心として、送風装置３０が下方へ落下する方向に回転しようとする。このため、回転中心に位置していない雄ネジ４５が挿入されている開口部５６の凹部５８は、前方又は後方へ移動しようとする。しかしながら、本実施の形態では、上下方向の異なる２箇所に開口部５６が設けられている。すなわち、本実施の形態では、上下方向の異なる２箇所に凹部５８が設けられている。このため、回転中心に位置していない雄ネジ４５が挿入されている開口部５６の凹部５８は、雄ネジ４５によって移動が規制される。したがって、送風装置３０及びモータ支持部５０は、雄ネジ４５のいずれか１つの位置を回転中心として回転しない。 In this state, when the air blower 30 and the motor support 50 are viewed from the side, the air blower 30 and the motor support 50 are blown around the position of any one of the male screws 45 as a rotation center due to the weight of the air blower 30. The device 30 tries to rotate in the direction of dropping downward. For this reason, the recessed part 58 of the opening part 56 in which the male screw 45 which is not located in the rotation center is inserted tends to move forward or backward. However, in the present embodiment, openings 56 are provided at two different locations in the vertical direction. That is, in the present embodiment, the recesses 58 are provided at two different locations in the vertical direction. For this reason, the movement of the concave portion 58 of the opening 56 into which the male screw 45 not positioned at the rotation center is inserted is restricted by the male screw 45. Therefore, the air blower 30 and the motor support part 50 do not rotate with the position of any one of the male screws 45 as the rotation center.
　このため、雄ネジ４５のそれぞれが開口部５６における前側の凹部５８に挿入されると、熱交換部２１が前後方向に２つ並設された熱交換器２０に対して、送風装置３０が正規の位置に配置された状態が維持される。この状態において雄ネジ４５のそれぞれを基部４１のネジ固定部４２にねじ込んでいくと、基部４１と雄ネジ４５の頭部との間にモータ支持部５０の脚部５５が挟持される。これにより、モータ支持部５０は、基部４１に固定される。すなわち、モータ支持部５０に取り付けられた送風装置３０は、熱交換部２１が前後方向に２つ並設された熱交換器２０に対して正規の位置に固定される。このように、本実施の形態に係る室外機１００においては、熱交換部２１が前後方向に２つ並設された熱交換器２０に対する正規の位置に、送風装置３０を容易に固定することができる。 For this reason, when each of the male screws 45 is inserted into the front recess 58 in the opening 56, the blower 30 is properly connected to the heat exchanger 20 in which the two heat exchanging portions 21 are arranged in the front-rear direction. The state arranged at the position of is maintained. When each of the male screws 45 is screwed into the screw fixing portion 42 of the base portion 41 in this state, the leg portion 55 of the motor support portion 50 is sandwiched between the base portion 41 and the head portion of the male screw 45. Thereby, the motor support portion 50 is fixed to the base portion 41. That is, the air blower 30 attached to the motor support part 50 is fixed to a regular position with respect to the heat exchanger 20 in which two heat exchange parts 21 are arranged in the front-rear direction. As described above, in the outdoor unit 100 according to the present embodiment, the air blower 30 can be easily fixed at a regular position with respect to the heat exchanger 20 in which two heat exchanging portions 21 are arranged in the front-rear direction. it can.
　また、上述のように、雄ネジ４５のそれぞれが開口部５６における前側の凹部５８に挿入された状態では、雄ネジ４５が緩んでいても、送風装置３０の位置がずれることが抑制される。このため、本実施の形態に係る室外機１００においては、室外機１００の運転時又は輸送時等の振動によって雄ネジ４５が緩んでいても、送風装置３０の位置が維持される。すなわち、本実施の形態に係る室外機１００においては、室外機１００の運転時又は輸送時等の振動によって雄ネジ４５が緩んでいても、熱交換部２１が前後方向に２つ並設された熱交換器２０に対する正規の位置から、送風装置３０が移動することを抑制できる。また、送風装置３０が正規の位置にあるときの所望の角度からずれてしまうことも抑制できる。 Further, as described above, in a state where each of the male screws 45 is inserted into the front concave portion 58 in the opening 56, even if the male screw 45 is loosened, the position of the blower 30 is prevented from shifting. For this reason, in the outdoor unit 100 according to the present embodiment, the position of the blower 30 is maintained even if the male screw 45 is loosened due to vibration during operation or transportation of the outdoor unit 100. That is, in the outdoor unit 100 according to the present embodiment, even if the male screw 45 is loosened due to vibration during operation or transportation of the outdoor unit 100, the two heat exchange parts 21 are arranged in the front-rear direction. It can suppress that the air blower 30 moves from the regular position with respect to the heat exchanger 20. FIG. Moreover, it can also suppress that it deviates from the desired angle when the air blower 30 exists in a regular position.
　ここで、上述のように、基部４１には凸部４３が設けられ、モータ支持部５０の脚部５５には２つの貫通孔５９が形成されている。そして、図９及び図１０に示すように、熱交換部２１が前後方向に２つ並設された熱交換器２０に対して、送風装置３０が正規の位置に配置された状態となった際、凸部４３が前側の貫通孔５９に挿入された状態となる。また、図１３に示すように、熱交換部２１が前後方向に２つ並設された熱交換器２０に対して、送風装置３０が正規の位置に配置されていない場合、凸部４３が前側の貫通孔５９に挿入されずに脚部５５と干渉する。このため、雄ネジ４５でモータ支持部５０と基部４１とを固定した際、脚部５５がひずんでしまう。したがって、本実施の形態に係る室外機１００は、熱交換部２１が前後方向に２つ並設された熱交換器２０に対して送風装置３０が正規の位置に配置されたことを容易に確認することもできる。 Here, as described above, the base portion 41 is provided with the convex portion 43, and the leg portion 55 of the motor support portion 50 is formed with two through holes 59. And as shown in FIG.9 and FIG.10, when the air blower 30 will be in the state arrange | positioned in the regular position with respect to the heat exchanger 20 with which the two heat exchange parts 21 were arranged in the front-back direction. The convex portion 43 is inserted into the front through hole 59. Moreover, as shown in FIG. 13, when the air blower 30 is not arrange | positioned in the regular position with respect to the heat exchanger 20 with which the two heat exchange parts 21 were arranged in the front-back direction, the convex part 43 is a front side. It is not inserted into the through hole 59 and interferes with the leg portion 55. For this reason, when the motor support part 50 and the base part 41 are fixed with the male screw 45, the leg part 55 will be distorted. Therefore, the outdoor unit 100 according to the present embodiment easily confirms that the air blower 30 is disposed at the regular position with respect to the heat exchanger 20 in which the two heat exchange units 21 are arranged in the front-rear direction. You can also
　一方、熱交換部２１が前後方向に３つ並設された熱交換器２０が筐体１に設けられる場合、雄ネジ４５のそれぞれが緩んでいる状態において、送風装置３０及びモータ支持部５０を前方へ移動させる。送風装置３０及びモータ支持部５０を前方へ移動させていくと、雄ネジ４５のそれぞれが、開口部５６における後ろ側の凹部５８の下方に位置することとなる。この状態になると、図１１及び図１２に示すように、送風装置３０及びモータ支持部５０の重みによってモータ支持部５０が下方へ落下し、雄ネジ４５のそれぞれが、開口部５６における後ろ側の凹部５８に挿入される。 On the other hand, when the heat exchanger 20 in which three heat exchange parts 21 are arranged in parallel in the front-rear direction is provided in the housing 1, the blower 30 and the motor support part 50 are connected in a state where each of the male screws 45 is loose. Move forward. When the blower 30 and the motor support portion 50 are moved forward, each of the male screws 45 is positioned below the rear concave portion 58 in the opening 56. In this state, as shown in FIGS. 11 and 12, the motor support 50 falls downward due to the weight of the blower 30 and the motor support 50, and each of the male screws 45 is located on the rear side of the opening 56. It is inserted into the recess 58.
　この状態では、送風装置３０及びモータ支持部５０を側面視した場合、送風装置３０及びモータ支持部５０は、送風装置３０の重みにより、雄ネジ４５のいずれか１つの位置を回転中心として、送風装置３０が下方へ落下する方向に回転しようとする。しかしながら、本実施の形態では、上下方向の異なる２箇所に開口部５６が設けられている。すなわち、本実施の形態では、上下方向の異なる２箇所に凹部５８が設けられている。このため、上述のように、送風装置３０及びモータ支持部５０は、雄ネジ４５のいずれか１つの位置を回転中心として回転しない。 In this state, when the air blower 30 and the motor support 50 are viewed from the side, the air blower 30 and the motor support 50 are blown around the position of any one of the male screws 45 as a rotation center due to the weight of the air blower 30. The device 30 tries to rotate in the direction of dropping downward. However, in the present embodiment, openings 56 are provided at two different locations in the vertical direction. That is, in the present embodiment, the recesses 58 are provided at two different locations in the vertical direction. For this reason, as above-mentioned, the air blower 30 and the motor support part 50 do not rotate centering on any one position of the external thread 45. As shown in FIG.
　このため、雄ネジ４５のそれぞれが開口部５６における後ろ側の凹部５８に挿入されると、熱交換部２１が前後方向に３つ並設された熱交換器２０に対して、送風装置３０が正規の位置に配置された状態が維持される。この状態において雄ネジ４５のそれぞれを基部４１のネジ固定部４２にねじ込んでいくと、基部４１と雄ネジ４５の頭部との間にモータ支持部５０の脚部５５が挟持される。これにより、モータ支持部５０は、基部４１に固定される。すなわち、モータ支持部５０に取り付けられた送風装置３０は、熱交換部２１が前後方向に３つ並設された熱交換器２０に対して正規の位置に固定される。このように、本実施の形態に係る室外機１００においては、熱交換部２１が前後方向に３つ並設された熱交換器２０に対する正規の位置に、送風装置３０を容易に固定することができる。 For this reason, when each of the male screws 45 is inserted into the recess 58 on the rear side of the opening 56, the blower 30 is provided to the heat exchanger 20 in which three heat exchange portions 21 are arranged in the front-rear direction. The state of being placed at the normal position is maintained. When each of the male screws 45 is screwed into the screw fixing portion 42 of the base portion 41 in this state, the leg portion 55 of the motor support portion 50 is sandwiched between the base portion 41 and the head portion of the male screw 45. Thereby, the motor support portion 50 is fixed to the base portion 41. That is, the air blower 30 attached to the motor support part 50 is fixed to a regular position with respect to the heat exchanger 20 in which three heat exchange parts 21 are arranged in parallel in the front-rear direction. As described above, in the outdoor unit 100 according to the present embodiment, the air blower 30 can be easily fixed at a regular position with respect to the heat exchanger 20 in which the three heat exchange units 21 are arranged in the front-rear direction. it can.
　また、上述のように、雄ネジ４５のそれぞれが開口部５６における後ろ側の凹部５８に挿入された状態では、雄ネジ４５が緩んでいても、送風装置３０の位置がずれることが抑制される。このため、本実施の形態に係る室外機１００においては、室外機１００の運転時又は輸送時等の振動によって雄ネジ４５が緩んでいても、熱交換部２１が前後方向に３つ並設された熱交換器２０に対する正規の位置から、送風装置３０が移動することを抑制できる。また、送風装置３０が正規の位置にあるときの所望の角度からずれてしまうことも抑制できる。 In addition, as described above, in a state where each of the male screws 45 is inserted into the recessed portion 58 on the rear side in the opening portion 56, even if the male screw 45 is loosened, the position of the blower device 30 is suppressed from shifting. . For this reason, in the outdoor unit 100 according to the present embodiment, even if the male screw 45 is loosened due to vibration during operation or transportation of the outdoor unit 100, three heat exchange parts 21 are arranged in the front-rear direction. It is possible to suppress the air blower 30 from moving from a normal position with respect to the heat exchanger 20. Moreover, it can also suppress that it deviates from the desired angle when the air blower 30 exists in a regular position.
　また、上述のように、基部４１には凸部４３が設けられ、モータ支持部５０の脚部５５には２つの貫通孔５９が形成されている。そして、図１１及び図１２に示すように、熱交換部２１が前後方向に３つ並設された熱交換器２０に対して、送風装置３０が正規の位置に配置された状態となった際、凸部４３が後ろ側の貫通孔５９に挿入された状態となる。また、熱交換部２１が前後方向に３つ並設された熱交換器２０に対して、送風装置３０が正規の位置に配置されていない場合、凸部４３が後ろ側の貫通孔５９に挿入されずに脚部５５と干渉する。このため、雄ネジ４５でモータ支持部５０と基部４１とを固定した際、脚部５５がひずんでしまう。したがって、本実施の形態に係る室外機１００は、熱交換部２１が前後方向に３つ並設された熱交換器２０に対して送風装置３０が正規の位置に配置されたことを容易に確認することもできる。 Further, as described above, the base portion 41 is provided with the convex portion 43, and the leg portion 55 of the motor support portion 50 is formed with two through holes 59. And as shown in FIG.11 and FIG.12, when the air blower 30 will be in the state arrange | positioned in the regular position with respect to the heat exchanger 20 with which the three heat exchange parts 21 were arranged in parallel by the front-back direction. Then, the convex portion 43 is inserted into the rear through hole 59. Further, when the air blower 30 is not disposed at a regular position with respect to the heat exchanger 20 in which the three heat exchange portions 21 are arranged in the front-rear direction, the convex portion 43 is inserted into the rear through hole 59. Without interfering with the leg 55. For this reason, when the motor support part 50 and the base part 41 are fixed with the male screw 45, the leg part 55 will be distorted. Therefore, the outdoor unit 100 according to the present embodiment easily confirms that the air blower 30 is disposed at a regular position with respect to the heat exchanger 20 in which three heat exchange portions 21 are arranged in the front-rear direction. You can also
　ここで、同一の開口部５６に設けられた２つの凹部５８は、前後方向に規定間隔Ｌを空けて設けられている。また、図１１に示すように、熱交換部２１の前後方向の厚みは、厚みＴとなっている。そして、規定間隔Ｌは、厚みＴと同じ値となっている。このため、熱交換部２１が前後方向に３つ並設された熱交換器２０に対する送風装置３０のプロペラファン３１の正規の位置と、熱交換部２１が前後方向に２つ並設された熱交換器２０に対する送風装置３０のプロペラファン３１の正規の位置とは、熱交換器２０と送風装置３０との距離が同じになる。 Here, the two recesses 58 provided in the same opening 56 are provided with a specified interval L in the front-rear direction. As shown in FIG. 11, the thickness of the heat exchanging portion 21 in the front-rear direction is a thickness T. The specified interval L is the same value as the thickness T. For this reason, the normal position of the propeller fan 31 of the blower device 30 with respect to the heat exchanger 20 in which the three heat exchanging parts 21 are arranged in the front-rear direction, and the heat in which the two heat exchanging parts 21 are arranged in the front-rear direction. The distance between the heat exchanger 20 and the blower 30 is the same as the normal position of the propeller fan 31 of the blower 30 with respect to the exchanger 20.
　送風装置３０による騒音の原因の一つは、プロペラファン３１の回転によって発生する気流が熱交換器２０にぶつかることにある。この際、プロペラファン３１と熱交換器２０の距離が近ければ近いほど、気流の速度が増大し、騒音も大きくなる。本実施の形態の場合、熱交換部２１が前後方向に３つ並設された熱交換器２０に対する送風装置３０のプロペラファン３１の正規の位置と、熱交換部２１が前後方向に２つ並設された熱交換器２０に対する送風装置３０のプロペラファン３１の正規の位置とは、熱交換器２０と送風装置３０との距離が同じになる。このため、異なる数の熱交換部２１を並設した熱交換器２０を用いた場合でも、送風装置３０に起因する騒音を略同等にでき、室外機１００の静音性を一定に保つことができる。 One of the causes of noise caused by the blower 30 is that the airflow generated by the rotation of the propeller fan 31 hits the heat exchanger 20. At this time, the closer the distance between the propeller fan 31 and the heat exchanger 20 is, the higher the speed of the airflow and the greater the noise. In the case of the present embodiment, the normal position of the propeller fan 31 of the blower device 30 with respect to the heat exchanger 20 in which three heat exchange parts 21 are arranged in the front-rear direction, and two heat exchange parts 21 in the front-rear direction. The distance between the heat exchanger 20 and the blower 30 is the same as the normal position of the propeller fan 31 of the blower 30 with respect to the installed heat exchanger 20. For this reason, even when using the heat exchanger 20 in which different numbers of heat exchanging units 21 are arranged in parallel, the noise caused by the blower 30 can be made substantially equal, and the silence of the outdoor unit 100 can be kept constant. .
　なお、本実施の形態で示した室外機１００は、あくまでも一例である。例えば、筐体１に、異なる数の熱交換部２１を並設した３種類以上の熱交換器２０を搭載できる構成としてもよい。この場合、開口部５６のそれぞれに、熱交換器２０の種類と同数の凹部５８を、規定間隔Ｌずつ空けて設ければよい。また例えば、筐体１に搭載できる熱交換器２０を１種類としてもよい。この場合、開口部５６のそれぞれに、１つの凹部５８を設ければよい。メンテナンス等の際、正規の位置から、送風装置３０を移動させることができる。 Note that the outdoor unit 100 shown in this embodiment is merely an example. For example, it is good also as a structure which can mount in the housing | casing 1 the three or more types of heat exchanger 20 which arranged the heat exchange part 21 of different number in parallel. In this case, the same number of recesses 58 as the type of the heat exchanger 20 may be provided in each of the openings 56 with a predetermined interval L therebetween. For example, the heat exchanger 20 that can be mounted on the housing 1 may be one type. In this case, one recess 58 may be provided in each of the openings 56. During maintenance or the like, the blower 30 can be moved from a regular position.
　また例えば、開口部５６の数も任意である。脚部５５のそれぞれに設けられる開口部５６は、少なくとも１つあればよい。この際、２つの開口部５６が上下方向に異なる位置に配置されていれば、上述のように、雄ネジ４５の１つを回転中心として送風装置３０が回転することを抑制できる。すなわち、正規の位置から送風装置３０が移動することを抑制でき、送風装置３０が正規の位置にあるときの所望の角度からずれてしまうことも抑制できる。 Also, for example, the number of openings 56 is arbitrary. There may be at least one opening 56 provided in each of the legs 55. At this time, if the two openings 56 are arranged at different positions in the vertical direction, as described above, the rotation of the blower 30 around one of the male screws 45 can be suppressed. That is, it can suppress that the air blower 30 moves from a regular position, and it can also suppress that it deviates from the desired angle when the air blower 30 exists in a regular position.
