空気調和装置の室外機１００は、据付後、真後ろに家屋の壁面などが存在し、使用者が容易に触ることができない熱交換器１０の長辺部１１を吸込口の背面側開口部として露出させている。これにより、装置背面は、空気の流れを阻害する枠などの外郭部品が無く、送風効率が良い。 After installation, the outdoor unit 100 of the air conditioner exposes the long side portion 11 of the heat exchanger 10 as the opening on the back side of the suction port, which has a wall surface of the house directly behind it and cannot be easily touched by the user. I'm letting you. As a result, the back surface of the device has no outer parts such as a frame that obstructs the flow of air, and the ventilation efficiency is good.

また、空気調和装置の室外機１００は、熱交換器１０の短辺部１２が存在する室外機１００の側面側を、使用者が容易に触ることができるため、ケーシング７の装置側面部７ａで覆う。ケーシング７の装置側面部７ａには、吸込口となる通風可能な複数の開口部７ａ１が形成されている。 Further, since the outdoor unit 100 of the air conditioner can easily touch the side surface side of the outdoor unit 100 in which the short side portion 12 of the heat exchanger 10 is present, the side surface portion 7a of the apparatus 7 of the casing 7 can be used. cover. A plurality of ventilable openings 7a1 serving as suction ports are formed in the device side surface portion 7a of the casing 7.

なお、熱交換器ユニットは、上下に３つ以上複数積み重ねて熱交換器を構成してもよい。 The heat exchanger unit may be formed by stacking three or more heat exchanger units one above the other.

さらに、図２に示すように、熱交換器１０の長辺部１１の側端部１１ａは、支柱部８に対して複数個所でネジ２０ａ、２０ｂによりネジ止め固定されている。複数個所でのネジ止め固定は、上下に重なる２つの熱交換器ユニット１０ａ、１０ｂそれぞれを固定する。
ここで、熱交換器１０の短辺部１２側は、ネジ止めあるいは引掛け部材などによって設定箇所に定めて固定されない。熱交換器１０の短辺部１２側は、天板９によって底板１に押圧固定されている。Further, as shown in FIG. 2, the side end portion 11a of the long side portion 11 of the heat exchanger 10 is screwed and fixed to the strut portion 8 at a plurality of locations by screws 20a and 20b. For screw fixing at a plurality of places, two heat exchanger units 10a and 10b that overlap vertically are fixed.
Here, the short side portion 12 side of the heat exchanger 10 is not fixed at the set location by screwing or a hooking member. The short side portion 12 side of the heat exchanger 10 is pressed and fixed to the bottom plate 1 by the top plate 9.

図３は、本発明の実施の形態に係る空気調和装置の室外機１００に搭載される熱交換器１０を示す分解斜視図である。図３に示すように、上下に重なる２つの熱交換器ユニット１０ａ、１０ｂそれぞれは、Ｕ字状に加工した銅あるいはアルミなどの金属配管１４を複数積み重ねている。また、上下に重なる２つの熱交換器ユニット１０ａ、１０ｂそれぞれは、複数の金属配管１４を通す穴が開いたアルミなどの金属板１５を、複数枚間隔を設け配置されている。上下に重なる２つの熱交換器ユニット１０ａ、１０ｂそれぞれは、複数の金属配管１４と、複数の金属板１５と、を密着加工することで構成されている。 FIG. 3 is an exploded perspective view showing a heat exchanger 10 mounted on the outdoor unit 100 of the air conditioner according to the embodiment of the present invention.

Each of the two heat exchanger units 10a and 10b that overlap vertically is configured by closely processing a plurality of metal pipes 14 and a plurality of metal plates 15.

また、上下に重なる２つの熱交換器ユニット１０ａ、１０ｂそれぞれは、長辺部１１に角部１３を介して短辺部１２を連続させたＬ字状に形成されている。上下に重なる２つの熱交換器ユニット１０ａ、１０ｂは、異なる高さであるが、製造バラツキによる形状誤差などの通風方向のずれを有するＬ字状である。通風方向のずれは、曲げ工程時に発生する曲げＲ寸法違いの製造バラツキによるものが大きい。 Further, each of the two heat exchanger units 10a and 10b that are vertically overlapped is formed in an L shape in which the short side portion 12 is continuous with the long side portion 11 via the corner portion 13. The two heat exchanger units 10a and 10b that are vertically overlapped have different heights, but are L-shaped with deviations in the ventilation direction such as shape errors due to manufacturing variations. The deviation in the ventilation direction is largely due to manufacturing variations in bending R dimensions that occur during the bending process.

上下に重なる２つの熱交換器ユニット１０ａ、１０ｂそれぞれは、長辺部１１の側端部１１ａにて、複数の金属配管１４が室外機１００の接続配管３と繋がる。 In each of the two heat exchanger units 10a and 10b that overlap vertically, a plurality of metal pipes 14 are connected to the connection pipe 3 of the outdoor unit 100 at the side end portion 11a of the long side portion 11.

上下に重なる２つの熱交換器ユニット１０ａ、１０ｂそれぞれは、短辺部１２の側端部１２ａにて、複数の金属配管１４がＵターンし、Ｕターン部１６を設けた端面が構成されている。 In each of the two heat exchanger units 10a and 10b that overlap vertically, a plurality of metal pipes 14 make a U-turn at the side end portion 12a of the short side portion 12, and an end surface provided with the U-turn portion 16 is formed. ..

熱交換器１０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相対位置を規制する第１規制部材３０を備えている。 The heat exchanger 10 includes a first regulating member 30 that regulates the relative positions of the heat exchanger units 10a and 10b that are vertically adjacent to each other.

熱交換器１０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相対位置を規制する第３規制部材５０を備えている。 The heat exchanger 10 includes a third regulating member 50 that regulates the relative positions of the heat exchanger units 10a and 10b that are vertically adjacent to each other.

図４は、本発明の実施の形態に係る第１規制部材３０を示す斜視図である。図４に示すように、第１規制部材３０は、長辺部１１の一部と長辺部１１から連続する角部１３の一部との間にて、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の通風方向の流入面部と流出面部とを挟み込んで規制する。第１規制部材３０は、長辺部１１の一部と角部１３の長辺部１１に連続する一部とに接するが、短辺部１２の一部と角部１３の短辺部１２に連続する一部とには接しない。第１規制部材３０は、金属で構成されている。 FIG. 4 is a perspective view showing the first regulating member 30 according to the embodiment of the present invention. As shown in FIG. 4, the first regulating member 30 is vertically adjacent to the heat exchanger unit 10a between a part of the long side portion 11 and a part of the corner portion 13 continuous from the long side portion 11. The inflow surface portion and the outflow surface portion in the ventilation direction of 10b are sandwiched and regulated. The first regulating member 30 is in contact with a part of the long side portion 11 and a part continuous with the long side portion 11 of the corner portion 13, but is attached to a part of the short side portion 12 and the short side portion 12 of the corner portion 13. Do not touch a continuous part. The first regulatory member 30 is made of metal.

第１規制部材３０には、上側の熱交換器ユニット１０ａの通風方向の流入面部と流出面部とを挟み込んで規制する２つのリブ３１、３２が設けられている。２つのリブ３１、３２は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ間に挟まれる基部３３から上方に突出する。流出面部に接触するリブ３２には、上側の熱交換器ユニット１０ａがスムーズに挿入できるように上方の先端の角度を広げた屈曲部３２ａが設けられている。 The first regulating member 30 is provided with two ribs 31 and 32 that sandwich and regulate the inflow surface portion and the outflow surface portion in the ventilation direction of the upper heat exchanger unit 10a. The two ribs 31 and 32 project upward from the base 33 sandwiched between the vertically adjacent heat exchanger units 10a and 10b. The rib 32 in contact with the outflow surface portion is provided with a bent portion 32a having a widened upper tip angle so that the upper heat exchanger unit 10a can be smoothly inserted.

第１規制部材３０の基部３３には、上側の熱交換器ユニット１０ａで発生した露をドレン水として下方に流通させる複数のドレン水通し孔３４が形成されている。 A plurality of drain water through holes 34 are formed in the base 33 of the first regulating member 30 to allow dew generated in the upper heat exchanger unit 10a to flow downward as drain water.

第１規制部材３０には、下側の熱交換器ユニット１０ｂの通風方向の流入面部と流出面部とを挟み込んで規制する２つのリブ３５、３６が設けられている。２つのリブ３５、３６は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ間に挟まれる基部３３から下方に突出する。流出面部に接触するリブ３６には、下側の熱交換器ユニット１０ｂがスムーズに挿入できるように下方の先端の角度を広げた屈曲部３６ａが設けられている。 The first regulating member 30 is provided with two ribs 35 and 36 that sandwich and regulate the inflow surface portion and the outflow surface portion in the ventilation direction of the lower heat exchanger unit 10b. The two ribs 35 and 36 project downward from the base 33 sandwiched between the vertically adjacent heat exchanger units 10a and 10b. The rib 36 in contact with the outflow surface portion is provided with a bent portion 36a having a widened lower tip angle so that the lower heat exchanger unit 10b can be smoothly inserted.

流入面部に接触する２つのリブ３１、３５は、１枚の板状部材から切り取って上下それぞれの方向に基部３３から折り曲げられている。リブ３１には、リブ３５を切り取った抜き孔３１ａが形成されている。流出面部に接触する２つのリブ３２、３６は、１枚の板状部材から切り取って上下それぞれの方向に基部から折り曲げられている。これらにより、４つのリブ３１、３２、３５、３６は、上下に隣接する熱交換器ユニット１０ａ、１０ｂそれぞれの規制を少ない材料で実施している。 The two ribs 31 and 35 that come into contact with the inflow surface portion are cut from one plate-shaped member and bent from the base portion 33 in each of the vertical directions. The rib 31 is formed with a hole 31a from which the rib 35 is cut out. The two ribs 32 and 36 that come into contact with the outflow surface portion are cut from one plate-shaped member and bent from the base portion in each of the vertical directions. As a result, the four ribs 31, 32, 35, and 36 are regulated by the heat exchanger units 10a and 10b adjacent to each other with less material.

第１規制部材３０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂのうち上側の熱交換器ユニット１０ａの隣り合う金属板１５間に差し込まれた凸部３７を有している。凸部３７は、上側の熱交換器ユニット１０ａの長辺部１１にて、金属板１５間に差し込まれる。これにより、凸部３７は、第１規制部材３０の横方向の位置ずれを防止している。このため、第１規制部材３０は、上側の熱交換器ユニット１０ａと一緒に長辺部１１の長手方向である左右方向に移動可能となる。 The first regulating member 30 has a convex portion 37 inserted between adjacent metal plates 15 of the upper heat exchanger unit 10a among the heat exchanger units 10a and 10b adjacent to the upper and lower sides. The convex portion 37 is inserted between the metal plates 15 at the long side portion 11 of the upper heat exchanger unit 10a. As a result, the convex portion 37 prevents the first regulating member 30 from being displaced in the lateral direction. Therefore, the first regulating member 30 can move together with the upper heat exchanger unit 10a in the left-right direction, which is the longitudinal direction of the long side portion 11.

ここで、凸部を下側の熱交換器ユニット１０ｂにも設けた場合には、外部からの衝撃により熱交換器１０の複数の金属板１５の変形や、衝撃により上下に重なる２つの熱交換器ユニット１０ａ、１０ｂが左右でずれたまま固定されるなど問題が生じる。実施の形態のように、凸部３７を上側の熱交換器ユニット１０ａのみに設けることにより、衝撃が発生した場合でも第１規制部材３０は、上側の熱交換器ユニット１０ａと共に移動するが、下側の熱交換器ユニット１０ｂとは一緒に移動しない。そのため、金属板１５の変形を抑制し、かつ、衝撃後もとの位置に戻ることができ、長辺部１１の長手方向である左右方向の位置ずれが抑制できる。 Here, when the convex portion is also provided on the lower heat exchanger unit 10b, the plurality of metal plates 15 of the heat exchanger 10 are deformed by an external impact, and two heat exchanges that are vertically overlapped by the impact are exchanged. Problems such as the device units 10a and 10b being fixed while being displaced from side to side occur. By providing the convex portion 37 only on the upper heat exchanger unit 10a as in the embodiment, the first regulating member 30 moves together with the upper heat exchanger unit 10a even when an impact occurs, but the lower portion It does not move with the heat exchanger unit 10b on the side. Therefore, the deformation of the metal plate 15 can be suppressed, and the metal plate 15 can be returned to the original position after the impact, and the positional deviation in the left-right direction, which is the longitudinal direction of the long side portion 11, can be suppressed.

なお、実施の形態では、凸部は、上側の熱交換器ユニットの隣り合う金属板間に差し込まれている。しかし、凸部は、上側の熱交換器ユニットではなく、下側の熱交換器ユニットの隣り合う金属板間に差し込まれてもよい。 In the embodiment, the convex portion is inserted between adjacent metal plates of the upper heat exchanger unit. However, the convex portion may be inserted between adjacent metal plates of the lower heat exchanger unit instead of the upper heat exchanger unit.

図５は、本発明の実施の形態に係る第１規制部材３０により規制される範囲を示す図である。図５に示すように、第１規制部材３０は、斜線部で示した熱交換器１０の長辺部１１の一部に始点３０ａを有すると共に、熱交換器１０の角部１３のＲ曲線の半分の位置に終点３０ｂを有している。すなわち、第１規制部材３０は、長辺部１１の一部の始点３０ａと長辺部１１から連続する角部１３の半分の位置の終点３０ｂとの間にて上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相対位置を合わせている。このように、第１規制部材３０は、熱交換器１０の角部１３の全領域を４つのリブで固定せず、角部１３の途中までの範囲に設けている。これにより、上下に重なる２つの熱交換器ユニット１０ａ、１０ｂの曲げ工程時に発生する曲げＲ寸法違い（製造バラツキ）が吸収でき、通風方向のずれが長辺部１１側よりも短辺部１２側に大きく強制できる。図５に示す破線の短辺部１２は、通風方向にずれた熱交換器ユニット１０ａ、１０ｂの一方を現す。 FIG. 5 is a diagram showing a range regulated by the first regulating member 30 according to the embodiment of the present invention. As shown in FIG. 5, the first regulating member 30 has a start point 30a on a part of the long side portion 11 of the heat exchanger 10 shown by the shaded portion, and has an R curve of the corner portion 13 of the heat exchanger 10. It has an end point 30b at half the position. That is, the first regulating member 30 is a heat exchanger unit vertically adjacent to each other between a start point 30a of a part of the long side portion 11 and an end point 30b at a half position of the corner portion 13 continuous from the long side portion 11. The relative positions of 10a and 10b are aligned. As described above, the first regulating member 30 is provided in a range up to the middle of the corner portion 13 without fixing the entire region of the corner portion 13 of the heat exchanger 10 with the four ribs. As a result, it is possible to absorb the difference in bending R dimension (manufacturing variation) that occurs during the bending process of the two heat exchanger units 10a and 10b that overlap vertically, and the deviation in the ventilation direction is on the short side 12 side rather than the long side 11 side. Can be greatly forced into. The short side portion 12 of the broken line shown in FIG. 5 represents one of the heat exchanger units 10a and 10b displaced in the ventilation direction.

As shown in FIG. 6, the second regulating member 40 has a ventilation direction between the heat exchanger units 10a and 10b vertically adjacent to each other in the middle of the long side portions 11 of the heat exchanger units 10a and 10b adjacent to each other.

The two ribs 41 and 42 project upward from the base 43 sandwiched between the vertically adjacent heat exchanger units 10a and 10b. The rib 42 in contact with the outflow surface portion is provided with a bent portion 42a having a widened upper tip angle so that the upper heat exchanger unit 10a can be smoothly inserted.

第２規制部材４０の基部４３には、上側の熱交換器ユニット１０ａで発生した露をドレン水として下方に流通させる複数のドレン水通し孔４４が形成されている。 The base 43 of the second regulating member 40 is formed with a plurality of drain water through holes 44 for allowing the dew generated in the upper heat exchanger unit 10a to flow downward as drain water.

The two ribs 45 and 46 project downward from the base 43 sandwiched between the vertically adjacent heat exchanger units 10a and 10b. The rib 46 in contact with the outflow surface portion is provided with a bent portion 46a having a widened lower tip angle so that the lower heat exchanger unit 10b can be smoothly inserted.

流入面部に接触する２つのリブ４１、４５は、１枚の板状部材から切り取って上下それぞれの方向に基部４３から折り曲げられている。リブ４１には、リブ４５を切り取った抜き孔４１ａが形成されている。流出面部に接触する２つのリブ４２、４６は、１枚の板状部材から切り取って上下それぞれの方向に基部４３から折り曲げられている。リブ４６には、リブ４２を切り取った抜き孔４６ｂが形成されている。これらにより、４つのリブ４１、４２、４５、４６は、上下に隣接する熱交換器ユニット１０ａ、１０ｂそれぞれの規制を少ない材料で実施している。 The two ribs 41 and 45 that come into contact with the inflow surface portion are cut from one plate-shaped member and bent from the base portion 43 in each of the vertical directions. The rib 41 is formed with a punched hole 41a from which the rib 45 is cut out. The two ribs 42, 46 that come into contact with the outflow surface portion are cut from one plate-shaped member and bent from the base portion 43 in each of the vertical directions. The rib 46 is formed with a hole 46b from which the rib 42 is cut out. As a result, the four ribs 41, 42, 45, and 46 are regulated by the heat exchanger units 10a and 10b adjacent to each other with less material.

第２規制部材４０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂのうち上側の熱交換器ユニット１０ａの隣り合う金属板１５間に差し込まれた凸部４７ａ、４７ｂを有している。凸部４７ａ、４７ｂは、上側の熱交換器ユニット１０ａの長辺部１１にて、金属板１５間に差し込まれる。これにより、凸部４７ａ、４７ｂは、第２規制部材４０の横方向の位置ずれを防止している。このため、第２規制部材４０は、上側の熱交換器ユニット１０ａと一緒に長辺部１１の長手方向である左右方向に移動可能となる。 The second regulating member 40 has convex portions 47a and 47b inserted between adjacent metal plates 15 of the upper heat exchanger units 10a among the heat exchanger units 10a and 10b adjacent to the upper and lower sides. The convex portions 47a and 47b are inserted between the metal plates 15 at the long side portions 11 of the upper heat exchanger unit 10a. As a result, the convex portions 47a and 47b prevent the second regulating member 40 from being displaced in the lateral direction. Therefore, the second regulating member 40 can move together with the upper heat exchanger unit 10a in the left-right direction, which is the longitudinal direction of the long side portion 11.

ここで、凸部を下側の熱交換器ユニット１０ｂにも設けた場合には、外部からの衝撃により熱交換器１０の複数の金属板１５の変形や、衝撃により上下に重なる２つの熱交換器ユニット１０ａ、１０ｂが左右でずれたまま固定されるなど問題が生じる。実施の形態のように、凸部４７ａ、４７ｂを上側の熱交換器ユニット１０ａのみに設けることにより、衝撃が発生した場合でも第２規制部材４０は、上側の熱交換器ユニット１０ａと共に移動するが、下側の熱交換器ユニット１０ｂとは一緒に移動しない。そのため、金属板１５の変形を抑制し、かつ、衝撃後もとの位置に戻ることができ、長辺部１１の長手方向である左右方向の位置ずれが抑制できる。 Here, when the convex portion is also provided on the lower heat exchanger unit 10b, the plurality of metal plates 15 of the heat exchanger 10 are deformed by an external impact, and two heat exchanges that are vertically overlapped by the impact are exchanged. Problems such as the device units 10a and 10b being fixed while being displaced from side to side occur.

The claw portions 51a, 53a, 54a, and 56a are provided along the left-right direction of the U-turn portion 16 and are urged to the extent that the third regulating member 50 does not come off from the U-turn portion 16. One claw portion 51a, 54a is provided on each of the left and right sides of the insertion holes 51, 54.

図８は、本発明の実施の形態に係る空気調和装置の室外機１００に搭載される熱交換器１０を背面側から見た状態を示す斜視図である。図８に示すように、上下に重ねた２つの熱交換器ユニット１０ａ、１０ｂは、長辺部１１の側端部１１ａにて接続配管３に複数の金属配管１４を接続できるように、長辺部１１の側端部１１ａを揃えて組み合せられている。このために、第１規制部材３０と第２規制部材４０とが、長辺部１１にて、上下に重なる２つの熱交換器ユニット１０ａ、１０ｂ同士の相対的な位置を合わせている。これにより、上下に重ねた２つの熱交換器ユニット１０ａ、１０ｂの長辺部１１の表面は、通風方向のずれに起因する段差が小さく同様に均された平面となる。 FIG. 8 is a perspective view showing a state in which the heat exchanger 10 mounted on the outdoor unit 100 of the air conditioner according to the embodiment of the present invention is viewed from the rear side. As shown in FIG. 8, the two heat exchanger units 10a and 10b stacked one above the other have long sides so that a plurality of metal pipes 14 can be connected to the connection pipe 3 at the side end portion 11a of the long side portion 11. The side end portions 11a of the portions 11 are aligned and combined. For this reason, the first regulating member 30 and the second regulating member 40 align the relative positions of the two heat exchanger units 10a and 10b that are vertically overlapped on the long side portion 11. As a result, the surfaces of the long side portions 11 of the two heat exchanger units 10a and 10b stacked one above the other become a flat surface with a small step due to the deviation in the ventilation direction and similarly leveled.

一方、上下に重ねた２つの熱交換器ユニット１０ａ、１０ｂは、金属配管１４のＵターン部１６を有する短辺部１２の側端部１２ａにて第３規制部材５０を用いてしっかり固定するのではなく、上側の熱交換器ユニット１０ａと下側の熱交換器ユニット１０ｂとがバラバラに左右方向に移動できるように通風方向のずれを許容する遊びを持たせている。また、第１規制部材３０は、熱交換器１０の長辺部１１の一部と長辺部１１から連続する角部１３の途中までとを規制する。 On the other hand, the two heat exchanger units 10a and 10b stacked one above the other are firmly fixed by the third regulating member 50 at the side end portion 12a of the short side portion 12 having the U-turn portion 16 of the metal pipe 14. Instead, the upper heat exchanger unit 10a and the lower heat exchanger unit 10b are provided with a play that allows deviation in the ventilation direction so that they can move apart in the left-right direction. Further, the first regulating member 30 regulates a part of the long side portion 11 of the heat exchanger 10 and the middle of the corner portion 13 continuous from the long side portion 11.

これにより、上下に熱交換器ユニット１０ａ、１０ｂを積み重ねた場合に、製造バラツキから発生する通風方向でのずれに起因する段差１７は、熱交換器１０の長辺部１１側よりも短辺部１２側に大きく形成される。熱交換器１０では、通風方向のずれに起因する段差１７は、短辺部１２側に大きく形成されている。 As a result, when the heat exchanger units 10a and 10b are stacked one above the other, the step 17 caused by the deviation in the ventilation direction caused by the manufacturing variation is the shorter side portion than the long side portion 11 side of the heat exchanger 10. Largely formed on the 12 side. In the heat exchanger 10, the step 17 due to the deviation in the ventilation direction is largely formed on the short side portion 12 side.

なお、段差は、上下に重なる熱交換器ユニット間の通風方向でのずれに起因するので、図８に示す上方を向いた段差１７だけでなく、下方を向いた段差が発生しても問題ない。 Since the step is caused by the deviation of the heat exchanger units that overlap vertically in the ventilation direction, there is no problem even if a step facing downward is generated in addition to the step 17 facing upward as shown in FIG. ..

そして、段差１７を有する熱交換器１０の短辺部１２が存在する室外機１００の側面側は、ケーシング７の装置側面部７ａで覆われる。 The side surface side of the outdoor unit 100 in which the short side portion 12 of the heat exchanger 10 having the step 17 is present is covered with the device side surface portion 7a of the casing 7.

図９は、従来における空気調和装置の室外機に搭載される熱交換器２１０を背面側から見た状態を示す斜視図である。図９に示すように、熱交換器２１０は、室外機に収納された接続配管と接続される金属配管の接続端部を有する長辺部２１１の側端部２１１ａと、金属配管のＵターン部を有する短辺部２１２の側端部２１２ａと、の両方を揃えるように組み合わせている。そのため、熱交換器２１０は、上側の熱交換器ユニット２１０ａと、下側の熱交換器ユニット２１０ｂと、の合わせ部分は、長辺部２１１から角部２１３にわたって通風方向でのずれに起因する段差２１７が生じる。 FIG. 9 is a perspective view showing a state in which the heat exchanger 210 mounted on the outdoor unit of the conventional air conditioner is viewed from the rear side. As shown in FIG. 9, the heat exchanger 210 includes a side end portion 211a of a long side portion 211 having a connection end portion of a metal pipe connected to a connection pipe housed in an outdoor unit, and a U-turn portion of the metal pipe. It is combined with the side end portion 212a of the short side portion 212 having the above so as to align both. Therefore, in the heat exchanger 210, the mating portion between the upper heat exchanger unit 210a and the lower heat exchanger unit 210b has a step due to a deviation in the ventilation direction from the long side portion 211 to the corner portion 213. 217 occurs.

この場合には、熱交換器２１０の長辺部２１１が空気をスムーズに通風するために露出していると、据付作業者あるいは使用者は、段差２１７に容易に触ることができる。このため、段差２１７により怪我をしたり、衣類などが引っ掛かって傷ついてしまったりするなどの不具合が生じる。この不具合を対策するために、装置背面にネットなどを設ける場合には、熱交換器２１０に容易に触ることができない。しかし、部品点数が増加し、非経済的である。 In this case, if the long side portion 211 of the heat exchanger 210 is exposed for smooth ventilation of air, the installation operator or the user can easily touch the step 217. For this reason, there are problems such as injury due to the step 217 and damage caused by catching clothes and the like. When a net or the like is provided on the back surface of the device in order to deal with this problem, the heat exchanger 210 cannot be easily touched. However, the number of parts increases, which is uneconomical.

また、上側の熱交換器ユニット２１０ａと、下側の熱交換器ユニット２１０ｂと、の曲げ加工を、同じ設備上で同時に行うことにより、曲げ加工時に生じるバラツキを上下に重なる２つの熱交換器ユニット２１０ａ、２１０ｂで同じにし、積み重ねた時の段差２１７をなくせる。しかし、その場合には、設備の大型化あるいは生産場所が限定され、生産の増加に対応できないという問題が生じる。 Further, by simultaneously performing the bending process of the upper heat exchanger unit 210a and the lower heat exchanger unit 210b on the same equipment, the two heat exchanger units that are vertically overlapped with the variation generated during the bending process. The same applies to 210a and 210b, and the step 217 when stacked can be eliminated. However, in that case, there arises a problem that the equipment becomes large or the production place is limited, and it is not possible to cope with the increase in production.

実施の形態によれば、空気調和装置の室外機１００は、長辺部１１と、短辺部１２と、長辺部１１と短辺部１２とを繋いで屈曲した角部１３と、を有した２つの熱交換器ユニット１０ａ、１０ｂを上下に積み重ねた熱交換器１０を備えている。熱交換器１０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の間で発生した通風方向でのずれを長辺部１１側よりも短辺部１２側に大きく形成している。 According to the embodiment, the outdoor unit 100 of the air conditioner has a long side portion 11, a short side portion 12, and a corner portion 13 bent by connecting the long side portion 11 and the short side portion 12. It is provided with a heat exchanger 10 in which the two heat exchanger units 10a and 10b are stacked one above the other. The heat exchanger 10 forms a large deviation in the ventilation direction between the vertically adjacent heat exchanger units 10a and 10b on the short side portion 12 side rather than the long side portion 11 side.

この構成によれば、組立時に熱交換器ユニット１０ａ、１０ｂの折り曲げ角度は調整せず、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の間で発生した通風方向でのずれを短辺部１２側に大きくなるように組み立てられる。したがって、組立時に熱交換器ユニット１０ａ、１０ｂの折り曲げ角度の調整を必要とせず組立効率が向上できる。また、据付作業者あるいは使用者が上下に積み重ねた熱交換器ユニット１０ａ、１０ｂに触れられる装置背面などの長辺部１１が配置される箇所での、上下に積み重ねた熱交換器ユニット１０ａ、１０ｂの通風方向でのずれに起因する段差が抑制できる。 According to this configuration, the bending angle of the heat exchanger units 10a and 10b is not adjusted at the time of assembly, and the deviation in the ventilation direction generated between the heat exchanger units 10a and 10b adjacent to the top and bottom is caused by the short side portion 12. Assembled to be larger on the side. Therefore, it is not necessary to adjust the bending angle of the heat exchanger units 10a and 10b at the time of assembly, and the assembly efficiency can be improved. Further, the heat exchanger units 10a and 10b stacked vertically at a place where the long side portion 11 such as the back surface of the device where the installation worker or the user can touch the heat exchanger units 10a and 10b stacked vertically is arranged. It is possible to suppress the step caused by the deviation in the ventilation direction.

そのため、据付作業者あるいは使用者は、装置背面などの長辺部１１が配置される箇所にて、上下に積み重ねた熱交換器ユニット１０ａ、１０ｂの通風方向でのずれに起因する段差に容易に触ることができず、安全性が向上できる。また、据付作業者あるいは使用者が上下に積み重ねた熱交換器ユニット１０ａ、１０ｂに触れられる装置外観での目立つ長辺部１１が配置される箇所に、上下に積み重ねた熱交換器ユニット１０ａ、１０ｂの通風方向でのずれに起因する段差が抑制できる。このため、空気調和装置の室外機１００は、使用者に段差が目立つことによる製品不具合が生じているような不安感を抱かせない。 Therefore, the installation worker or the user can easily move the heat exchanger units 10a and 10b stacked one above the other to the step caused by the deviation in the ventilation direction at the place where the long side portion 11 is arranged, such as the back surface of the device. It cannot be touched and safety can be improved. Further, the heat exchanger units 10a and 10b stacked vertically at a place where a prominent long side portion 11 is arranged in the appearance of the device where the installation worker or the user can touch the heat exchanger units 10a and 10b stacked vertically. It is possible to suppress the step caused by the deviation in the ventilation direction. For this reason, the outdoor unit 100 of the air conditioner does not give the user anxiety that a product defect has occurred due to a conspicuous step.

実施の形態によれば、熱交換器１０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の間で発生した通風方向でのずれを、長辺部１１の一部と長辺部１１から連続する角部１３の一部との間にて上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相対位置を合わせて長辺部１１側よりも短辺部１２側に大きく形成している。 According to the embodiment, the heat exchanger 10 causes the deviation in the ventilation direction generated between the heat exchanger units 10a and 10b adjacent to the top and bottom from a part of the long side portion 11 and the long side portion 11. The heat exchanger units 10a and 10b that are vertically adjacent to each other with a part of the continuous corner portions 13 are aligned with each other and formed larger on the short side portion 12 side than on the long side portion 11 side.

この構成によれば、熱交換器１０は、長辺部１１の一部と長辺部１１から連続する角部１３の一部との間にて上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相対位置を合わせ、長辺部１１側の通風方向でのずれを短辺部１２側に強制できる。このため、組立時に熱交換器ユニット１０ａ、１０ｂの折り曲げ角度は調整せず、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の間で発生した通風方向でのずれを短辺部１２側に大きくなるように組み立てられる。 According to this configuration, the heat exchanger 10 has heat exchanger units 10a and 10b that are vertically adjacent to each other between a part of the long side portion 11 and a part of the corner portion 13 continuous from the long side portion 11. By aligning the relative positions of, the deviation in the ventilation direction on the long side portion 11 side can be forced to the short side portion 12 side. Therefore, the bending angle of the heat exchanger units 10a and 10b is not adjusted at the time of assembly, and the deviation in the ventilation direction generated between the heat exchanger units 10a and 10b adjacent to the top and bottom is large toward the short side portion 12. Assembled to be.

実施の形態によれば、空気調和装置の室外機１００は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相対位置を規制する第１規制部材３０を備えている。第１規制部材３０は、長辺部１１の一部と長辺部１１から連続する角部１３の一部との間にて上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の通風方向の流入面部と流出面部とを挟み込んで規制する。 According to the embodiment, the outdoor unit 100 of the air conditioner includes a first regulating member 30 that regulates the relative positions of the heat exchanger units 10a and 10b that are vertically adjacent to each other. The first regulating member 30 is an inflow of heat exchanger units 10a and 10b vertically adjacent to each other in the ventilation direction between a part of the long side portion 11 and a part of the corner portion 13 continuous from the long side portion 11. It regulates by sandwiching the surface part and the outflow surface part.

この構成によれば、熱交換器１０は、第１規制部材３０を用いて長辺部１１の一部と長辺部１１から連続する角部１３の一部との間にて上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相対位置を合わせ、長辺部１１側の通風方向でのずれを短辺部１２側に強制できる。 According to this configuration, the heat exchanger 10 is vertically adjacent to each other by using the first regulating member 30 between a part of the long side portion 11 and a part of the corner portion 13 continuous from the long side portion 11. By aligning the relative positions of the heat exchanger units 10a and 10b, the deviation of the long side portion 11 side in the ventilation direction can be forced to the short side portion 12 side.

実施の形態によれば、第１規制部材３０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士を相互間で長辺部１１の長手方向に移動可能とする。 According to the embodiment, the first regulating member 30 allows the heat exchanger units 10a and 10b that are vertically adjacent to each other to move between each other in the longitudinal direction of the long side portion 11.

この構成によれば、第１規制部材３０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相互間の長辺部１１の長手方向への移動を許容する。そのため、熱交換器１０は、変形などの損傷が抑制できる。 According to this configuration, the first regulating member 30 allows the long side portions 11 between the heat exchanger units 10a and 10b adjacent to each other to move in the longitudinal direction. Therefore, the heat exchanger 10 can suppress damage such as deformation.

実施の形態によれば、第１規制部材３０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂのうちどちらか一方の上部の熱交換器ユニット１０ａの隣り合う金属板１５間に差し込まれた凸部３７を有している。 According to the embodiment, the first regulating member 30 is a convex inserted between adjacent metal plates 15 of the heat exchanger units 10a on the upper portion of either of the heat exchanger units 10a and 10b adjacent to the top and bottom. It has a part 37.

この構成によれば、第１規制部材３０は、凸部３７を隣り合う金属板１５間に差し込んだ一方の上部の熱交換器ユニット１０ａと共に移動できる。そして、第１規制部材３０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相互間の移動を許容できる。 According to this configuration, the first regulating member 30 can move together with the heat exchanger unit 10a on the upper side of which the convex portion 37 is inserted between the adjacent metal plates 15. Then, the first regulating member 30 can allow the heat exchanger units 10a and 10b adjacent to each other to move between each other.

実施の形態によれば、空気調和装置の室外機１００は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相対位置を規制する第２規制部材４０を備えている。第２規制部材４０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士における長辺部１１の途中にて上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の通風方向の流入面部と流出面部とを挟み込んで規制する。 According to the embodiment, the outdoor unit 100 of the air conditioner includes a second regulating member 40 that regulates the relative positions of the heat exchanger units 10a and 10b that are vertically adjacent to each other. The second regulating member 40 includes an inflow surface portion and an outflow surface portion in the ventilation direction of the heat exchanger units 10a and 10b vertically adjacent to each other in the middle of the long side portions 11 of the heat exchanger units 10a and 10b adjacent to each other. To regulate by sandwiching.

この構成によれば、熱交換器１０は、第２規制部材４０を用いて長辺部１１の途中にて上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相対位置を合わせ、長辺部１１側の通風方向でのずれを強制できる。 According to this configuration, the heat exchanger 10 uses the second regulating member 40 to align the relative positions of the heat exchanger units 10a and 10b vertically adjacent to each other in the middle of the long side portion 11, and the long side portion 11 It is possible to force a deviation in the ventilation direction on the side.

そして、第２規制部材４０は、第１規制部材３０との２箇所で長辺部１１側の通風方向でのずれを短辺部１２側に強制するので、長辺部１１での通風方向でのずれに起因する段差をより小さくできる。 Then, since the second regulating member 40 forces the deviation in the ventilation direction on the long side portion 11 side to the short side portion 12 side at two points with the first regulating member 30, in the ventilation direction on the long side portion 11. The step caused by the deviation can be made smaller.

実施の形態によれば、空気調和装置の室外機１００は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の相対位置を規制する第３規制部材５０を備えている。第３規制部材５０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士における短辺部１２の側端部１２ａにて上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の上下方向を規制し、通風方向にずれを許容する遊びを持たせる。 According to the embodiment, the outdoor unit 100 of the air conditioner includes a third regulating member 50 that regulates the relative positions of the heat exchanger units 10a and 10b that are vertically adjacent to each other. The third regulating member 50 regulates the vertically adjacent heat exchanger units 10a and 10b at the side end portion 12a of the short side portion 12 of the heat exchanger units 10a and 10b adjacent to each other in the vertical direction. Give some play to allow deviation in the ventilation direction.

この構成によれば、熱交換器１０は、第３規制部材５０を用いて短辺部１２の側端部１２ａにて上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の上下方向を規制できる。このため、熱交換器１０は、短辺部１２の側端部１２ａにて上下に隣接する熱交換器ユニット１０ａ、１０ｂの上下間が開いてしまうことが無い。また、第３規制部材５０は、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の通風方向にずれを許容する遊びを持たせられる。このため、熱交換器１０は、短辺部１２側に強制した通風方向でのずれを保持したまま、短辺部１２の側端部１２ａの上下方向を規制できる。 According to this configuration, the heat exchanger 10 can regulate the vertical direction between the heat exchanger units 10a and 10b vertically adjacent to each other at the side end portion 12a of the short side portion 12 by using the third regulating member 50. Therefore, in the heat exchanger 10, the upper and lower sides of the heat exchanger units 10a and 10b adjacent to the upper and lower sides of the short side portion 12 do not open. Further, the third regulating member 50 is provided with a play that allows the heat exchanger units 10a and 10b that are vertically adjacent to each other to be displaced in the ventilation direction. Therefore, the heat exchanger 10 can regulate the vertical direction of the side end portion 12a of the short side portion 12 while maintaining the deviation in the ventilation direction forced on the short side portion 12 side.

実施の形態によれば、熱交換器１０は、長辺部１１を装置背面となるように露出させている。空気調和装置の室外機１００は、熱交換器１０の短辺部１２を覆い、通風可能な複数の開口部７ａ１が形成されたケーシング７を備えている。 According to the embodiment, the heat exchanger 10 exposes the long side portion 11 so as to be the back surface of the device. The outdoor unit 100 of the air conditioner includes a casing 7 that covers the short side portion 12 of the heat exchanger 10 and has a plurality of ventilable openings 7a1 formed therein.

この構成によれば、熱交換器１０は、長辺部１１を装置背面となるように露出させている。このため、据付作業者あるいは使用者が上下に積み重ねた熱交換器ユニット１０ａ、１０ｂに触れられる装置背面となるように露出した長辺部１１での、上下に積み重ねた熱交換器ユニット１０ａ、１０ｂの通風方向でのずれに起因する段差が抑制できる。 According to this configuration, the heat exchanger 10 exposes the long side portion 11 so as to be the back surface of the device. Therefore, the heat exchanger units 10a and 10b stacked vertically on the long side 11 exposed so as to be on the back surface of the device where the installation worker or the user can touch the heat exchanger units 10a and 10b stacked vertically. It is possible to suppress the step caused by the deviation in the ventilation direction.

そのため、据付作業者あるいは使用者は、装置背面となるように露出した長辺部１１にて、上下に積み重ねた熱交換器ユニット１０ａ、１０ｂの通風方向でのずれに起因する段差に容易に触ることができず、安全性が向上できる。また、据付作業者あるいは使用者が上下に積み重ねた熱交換器ユニット１０ａ、１０ｂに触れられる装置外観での目立つ装置背面となるように露出した長辺部１１に、上下に積み重ねた熱交換器ユニット１０ａ、１０ｂの通風方向でのずれに起因する段差が抑制できる。このため、空気調和装置の室外機１００は、使用者に装置背面の段差が目立つことによる製品不具合が生じているような不安感を抱かせない。 Therefore, the installation worker or the user can easily touch the step caused by the displacement of the heat exchanger units 10a and 10b stacked vertically on the long side portion 11 exposed so as to be the back surface of the device in the ventilation direction. It cannot be done and safety can be improved. Further, the heat exchanger units stacked vertically on the long side portion 11 exposed so as to be the back surface of the device which is conspicuous in the appearance of the device where the installation worker or the user can touch the heat exchanger units 10a and 10b stacked vertically. The step caused by the deviation of 10a and 10b in the ventilation direction can be suppressed. For this reason, the outdoor unit 100 of the air conditioner does not give the user anxiety that a product defect has occurred due to a conspicuous step on the back surface of the device.

また、ケーシング７は、熱交換器１０の短辺部１２を覆い、通風可能な複数の開口部７ａ１が形成されている。このため、熱交換器１０の短辺部１２側に大きく形成された通風方向でのずれあるいはずれに起因する段差１７は、ケーシング７に覆われて隠されている。また、ケーシング７には、通風可能な複数の開口部７ａ１が形成されていて、短辺部１２での熱交換器１０の効率の低下が抑制できる。 Further, the casing 7 covers the short side portion 12 of the heat exchanger 10, and a plurality of ventilable openings 7a1 are formed. For this reason, the step 17 caused by the deviation or deviation in the ventilation direction, which is largely formed on the short side portion 12 side of the heat exchanger 10, is covered and hidden by the casing 7. Further, a plurality of ventilable openings 7a1 are formed in the casing 7, so that a decrease in efficiency of the heat exchanger 10 at the short side portion 12 can be suppressed.

そのため、据付作業者あるいは使用者は、通風方向でのずれの大きな短辺部１２がケーシング７に覆われていて、上下に積み重ねた熱交換器ユニット１０ａ、１０ｂの通風方向でのずれに起因する段差１７に容易に触ることができず、安全性が向上できる。また、空気調和装置の室外機１００は、通風方向でのずれの大きな短辺部１２がケーシング７に覆われていて、使用者に通風方向でのずれに起因する段差１７が目立つことによる製品不具合が生じているような不安感を抱かせない。 Therefore, for the installation worker or the user, the short side portion 12 having a large deviation in the ventilation direction is covered with the casing 7, and the heat exchanger units 10a and 10b stacked vertically are caused by the deviation in the ventilation direction. The step 17 cannot be easily touched, and safety can be improved. Further, in the outdoor unit 100 of the air conditioner, the short side portion 12 having a large deviation in the ventilation direction is covered with the casing 7, and the user has a conspicuous step 17 due to the deviation in the ventilation direction. Do not give a feeling of anxiety that is occurring.

実施の形態によれば、空気調和装置の室外機１００は、ケーシング７に被さって熱交換器１０を下方向に押圧固定した天板９を備えている。 According to the embodiment, the outdoor unit 100 of the air conditioner includes a top plate 9 that covers the casing 7 and presses and fixes the heat exchanger 10 downward.

この構成によれば、天板９がケーシング７に被さって熱交換器１０を下方向に押圧固定している。このとき、天板９は、底板１とで挟み込むものであってインスレーションなどの軟らかい軟性部材を貼り付けたモータ取付台５を介して熱交換器１０を下方向に押圧固定できる。このため、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の間で発生した通風方向でのずれが短辺部１２側に大きく形成されても、熱交換器１０の短辺部１２側は天板９により押圧固定されるだけであるので、通風方向のずれが許容された状態で熱交換器１０がしっかりと固定できる。それにより、熱交換器１０の短辺部１２側では、ずれ量によって短辺部１２の位置が変わっても、ネジ止めあるいは引掛け部材などによって設定箇所に定めて固定する必要が無いので、部品点数が削減でき、組立効率が向上できる。 According to this configuration, the top plate 9 covers the casing 7 and presses and fixes the heat exchanger 10 downward. At this time, the top plate 9 is sandwiched between the bottom plate 1 and the heat exchanger 10 can be pressed and fixed downward via the motor mounting base 5 to which a soft flexible member such as an insulation is attached. Therefore, even if a large deviation in the ventilation direction occurs between the heat exchanger units 10a and 10b adjacent to each other on the upper and lower sides in the ventilation direction, the short side portion 12 side of the heat exchanger 10 is heaven. Since it is only pressed and fixed by the plate 9, the heat exchanger 10 can be firmly fixed in a state where the deviation in the ventilation direction is allowed. As a result, on the short side portion 12 side of the heat exchanger 10, even if the position of the short side portion 12 changes depending on the amount of displacement, it is not necessary to fix the heat exchanger 10 at a set location by screwing or a hooking member. The number of points can be reduced and the assembly efficiency can be improved.

実施の形態によれば、熱交換器ユニット１０ａ、１０ｂは、長辺部１１に角部１３を介して短辺部１２を連続させたＬ字状に形成されている。ケーシング７は、熱交換器１０の短辺部１２を覆う装置側面部７ａと、装置背面となった熱交換器１０の露出させた長辺部１１とは反対側の装置前面部７ｂと、を有している。空気調和装置の室外機１００は、ケーシング７の装置側面部７ａとは反対側の装置反対側側面部を構成し、熱交換器１０の長辺部１１の側端部１１ａが固定された支柱部８を備えている。天板９は、ケーシング７および支柱部８に被さって熱交換器１０を下方向に押圧固定している。 According to the embodiment, the heat exchanger units 10a and 10b are formed in an L shape in which the short side portion 12 is continuous with the long side portion 11 via the corner portion 13. The casing 7 includes a device side surface portion 7a that covers the short side portion 12 of the heat exchanger 10 and a device front surface portion 7b on the side opposite to the exposed long side portion 11 of the heat exchanger 10 that is the back surface of the device. Have. The outdoor unit 100 of the air conditioner constitutes a side surface portion of the casing 7 opposite to the device side surface portion 7a, and a support column portion to which the side end portion 11a of the long side portion 11 of the heat exchanger 10 is fixed. Equipped with 8. The top plate 9 covers the casing 7 and the support column 8 and presses and fixes the heat exchanger 10 downward.

この構成によれば、Ｌ字状に形成された熱交換器ユニット１０ａ、１０ｂから構成される熱交換器１０は、通風方向のずれを強制されて端部位置が揃った長辺部１１の側端部１１ａが支柱部８に固定されている。そして、天板９がケーシング７および支柱部８に被さって熱交換器１０を下方向に押圧固定している。このとき、天板９は、底板１とで挟み込むものであってインスレーションなどの軟らかい軟性部材を貼り付けたモータ取付台５を介して熱交換器１０を下方向に押圧固定できる。このため、上下に隣接する熱交換器ユニット１０ａ、１０ｂ同士の間で発生した通風方向でのずれが短辺部１２側に大きく形成されても、熱交換器１０の短辺部１２側は天板９により押圧固定されるだけであるので、通風方向のずれが許容された状態で熱交換器１０がしっかりと固定できる。それにより、熱交換器１０の短辺部１２側では、ずれ量によって短辺部１２の位置が変わっても、ネジ止めあるいは引掛け部材などによって設定箇所に定めて固定する必要が無いので、部品点数が削減でき、組立効率が向上できる。 According to this configuration, the heat exchanger 10 composed of the heat exchanger units 10a and 10b formed in an L shape is forced to deviate in the ventilation direction and is on the side of the long side portion 11 whose end positions are aligned. The end portion 11a is fixed to the strut portion 8. Then, the top plate 9 covers the casing 7 and the support column 8 to press and fix the heat exchanger 10 downward. At this time, the top plate 9 is sandwiched between the bottom plate 1 and the heat exchanger 10 can be pressed and fixed downward via the motor mounting base 5 to which a soft flexible member such as an insulation is attached. Therefore, even if a large deviation in the ventilation direction occurs between the heat exchanger units 10a and 10b adjacent to each other on the upper and lower sides in the ventilation direction, the short side portion 12 side of the heat exchanger 10 is heaven. Since it is only pressed and fixed by the plate 9, the heat exchanger 10 can be firmly fixed in a state where the deviation in the ventilation direction is allowed. As a result, on the short side portion 12 side of the heat exchanger 10, even if the position of the short side portion 12 changes depending on the amount of displacement, it is not necessary to fix the heat exchanger 10 at a set location by screwing or a hooking member. The number of points can be reduced and the assembly efficiency can be improved.

また、モータ取付台５は、天面側にインスレーションなどの軟らかい材料の軟性部材を貼り付けて天板９と接触する構成である。これにより、空気調和装置の室外機１００は、運転中の振動によるモータ取付台５と天板９との接触音が防止できる。 Further, the motor mounting base 5 has a configuration in which a soft member made of a soft material such as insulation is attached to the top surface side and comes into contact with the top plate 9. As a result, the outdoor unit 100 of the air conditioner can prevent the contact noise between the motor mounting base 5 and the top plate 9 due to vibration during operation.

なお、熱交換器ユニット１０ａ、１０ｂは、長辺部１１に角部１３を介して短辺部１２を連続させたＬ字状に形成されていた。しかし、本発明は、熱交換器ユニットが長辺部の両側に短辺部をそれぞれ有するＵ字状に形成されても適用できる。 The heat exchanger units 10a and 10b were formed in an L shape in which the short side portion 12 was continuous with the long side portion 11 via the corner portion 13. However, the present invention can be applied even if the heat exchanger unit is formed in a U shape having short side portions on both sides of the long side portion.
