しかしながら、従来のものでは、外側の熱交換部を底板に固定するものの、内側の熱交換部が固定されていないため、室外ユニットの搬送時等に、内側の熱交換部が搬送時の振動で動く恐れがあった。
これに対し、内側の熱交換部を固定した場合、内側の熱交換部にも管板等が必要になり、熱交換部の組立工程が複雑化すると共に部品点数が増し、部品管理が繁雑になる。
そこで、本発明の目的は、上述した従来の技術が有する課題を解消し、簡易な構成で、室外ユニットの搬送時における内側の熱交換部の移動を規制できる構造を有した空気調和機を提供することにある。 However, in the conventional one, the outer heat exchange part is fixed to the bottom plate, but the inner heat exchange part is not fixed. There was a fear of moving.
On the other hand, when the inner heat exchanging part is fixed, the inner heat exchanging part also requires a tube sheet, which complicates the assembly process of the heat exchanging part, increases the number of parts, and complicates parts management. Become.
Accordingly, an object of the present invention is to provide an air conditioner that has a structure that can eliminate the problems of the conventional techniques described above and that can regulate the movement of the inner heat exchanging unit when the outdoor unit is transported with a simple configuration. There is to do.

上記課題を解決するため、本発明は、複数の熱交換部を積層してＬ字状に曲げて形成した多列型の熱交換器を室外ユニットの底板上に配置した空気調和機において、前記熱交換器の一方の端部を管板を介して底板上に固定すると共に、前記Ｌ字状に曲げた他方の端部の内側下部を外側に押圧するように押さえ部材で底板上に固定したことを特徴とする。
この構成によれば、熱交換器の一方の端部を管板を介して底板上に固定すると共に、Ｌ字状に曲げた他方の端部の内側下部を外側に押圧するように押さえ部材で底板上に固定したので、熱交換器の一方の端部だけでなく、他方の端部においても内外の熱交換部を密着して固定することができる。従って、内外の熱交換部が別々に動いてしまう事態を回避でき、内外の熱交換部を別々に固定する管板部材を使用することなく、簡易な構成で、室外ユニット搬送時における内側の熱交換部の移動を規制することができる。 In order to solve the above problems, the present invention provides an air conditioner in which a multi-row heat exchanger formed by laminating a plurality of heat exchange portions and bending it in an L shape is disposed on a bottom plate of an outdoor unit. One end of the heat exchanger is fixed on the bottom plate through the tube plate, and fixed to the bottom plate by a pressing member so as to press the inner lower portion of the other end bent to the L shape outward. It is characterized by that.
According to this configuration, one end of the heat exchanger is fixed on the bottom plate via the tube plate, and the pressing member is used to press the inner lower portion of the other end bent in an L shape outward. Since it was fixed on the bottom plate, the inner and outer heat exchanging portions can be closely fixed not only at one end of the heat exchanger but also at the other end. Therefore, it is possible to avoid a situation in which the inner and outer heat exchanging parts move separately, and without using a tube plate member for fixing the inner and outer heat exchanging parts separately, the inner heat during the outdoor unit transportation can be achieved with a simple configuration. The movement of the exchange unit can be restricted.

上記構成において、前記他方の端部が前記押さえ部材で外側に押圧されて、前記押さえ部材と前記室外ユニットの底板の側面とに狭持されるようにしてもよい。この構成によれば、熱交換器の他方の端部が押さえ部材と室外ユニットの底板の側面とに狭持され、内外の熱交換部の密着度および他方の端部の支持力を向上することができる。
また、上記構成において、前記他方の端部で前記複数の熱交換部間がバンド止めされるようにしてもよい。この構成によれば、他方の端部については押さえ部材とバンドだけで固定され、熱交換器の取り付けや取り外しの作業を容易にできる。
また、上記構成において、前記押さえ部材が内側の熱交換部のベンド管を支持する支持溝部と、前記室外ユニットの底板の側面に固定する固定部とを一体に備えるようにしてもよい。この構成によれば、部品点数の増大を回避できると共に、支持溝部と固定部との寸法精度を確保し易くなる。 In the above-described configuration, the other end may be pressed outward by the pressing member and held between the pressing member and a side surface of the bottom plate of the outdoor unit. According to this configuration, the other end portion of the heat exchanger is sandwiched between the pressing member and the side surface of the bottom plate of the outdoor unit, and the close contact degree of the inner and outer heat exchange portions and the supporting force of the other end portion are improved. Can do.
Further, in the above configuration, the plurality of heat exchange units may be band-stopped at the other end. According to this configuration, the other end is fixed only by the pressing member and the band, and the heat exchanger can be easily attached or detached.
In the above configuration, the pressing member may integrally include a support groove portion that supports a bend pipe of an inner heat exchange portion and a fixing portion that is fixed to a side surface of the bottom plate of the outdoor unit. According to this configuration, it is possible to avoid an increase in the number of parts, and it is easy to ensure the dimensional accuracy between the support groove portion and the fixed portion.

本発明によれば、簡易な構成で、室外ユニットの搬送時における内側の熱交換部の移動を規制できる。   ADVANTAGE OF THE INVENTION According to this invention, a movement of an inner side heat exchange part at the time of conveyance of an outdoor unit can be controlled with a simple structure.

次に室外熱交換器１２およびその固定構造について説明する。
室外熱交換器１２は、複数（本実施形態では２個）のフィンチューブ型の熱交換部３１、３２を厚み方向に積層した多列型の熱交換器である。
各々の熱交換部３１、３２は、略水平方向に延びるチューブが縦一列で配置された単列の熱交換器であり、その両端部に上下のチューブをつなぐ鋼管製のＵベンド管３３が縦一列に接続される。また、この室外熱交換器１２では、機械室Ｂ側の端部１２Ｒに冷媒出入り口が設けられており、熱交換室Ａ側の端部１２Ｌは、この端部に設けてチューブ内を流れる冷媒をＵベンド管３３を介して端部１２Ｒ側に流す冷媒折り返し部とされている。 Next, the outdoor heat exchanger 12 and its fixing structure will be described.
The outdoor heat exchanger 12 is a multi-row heat exchanger in which a plurality (two in this embodiment) of fin-tube heat exchangers 31 and 32 are stacked in the thickness direction.
Each of the heat exchange units 31 and 32 is a single row heat exchanger in which tubes extending in a substantially horizontal direction are arranged in a vertical row, and U-bend pipes 33 made of steel pipes connecting the upper and lower tubes at both ends thereof are vertically arranged. Connected in a row. Further, in the outdoor heat exchanger 12, a refrigerant inlet / outlet is provided at the end 12R on the machine room B side, and the end 12L on the heat exchange chamber A side is provided with this refrigerant and flows the refrigerant flowing in the tube. A refrigerant folding portion that flows to the end 12R side through the U-bend pipe 33 is formed.

本構成の室外熱交換器１２は、Ｌ字状を有しているが、熱交換部３１、３２の各々をＬ字状に曲げた後に重ねるのではなく、直線状に延びた平型形状の熱交換部３１、３２を厚み方向に重ね、冷媒出入り側となる一方の端部１２Ｒの位置を揃えて同一の管板３５で連結し、冷媒折り返し側となる他方の端部１２Ｌを自由端とした状態で該端部１２Ｌ側を同時に屈曲することによってＬ字状に形成される。
ここで、Ｌ字状に曲げた他方の端部１２Ｌを自由端にするのは、Ｌ字形状への曲げ工程の際、外側に位置する熱交換部３１と内側に位置する熱交換部３２とで曲げ部１２Ｍの曲がり（曲率やカーブ長）に差異が生じて各熱交換部３１、３２の端部１２Ｌが同じ位置に揃わないからである。つまり、室外熱交換器１２の端部１２Ｌでは、外側の熱交換部３１ほど曲率が小さく、カーブ長が長くなるため、外側の熱交換部３１ほど内側の端部３２Ｌよりも奥まった位置にずれた段差部が形成される。 Although the outdoor heat exchanger 12 of this configuration has an L shape, it does not overlap after the heat exchange portions 31 and 32 are bent into an L shape, but has a flat shape extending linearly. The heat exchanging portions 31 and 32 are overlapped in the thickness direction, the positions of one end portion 12R on the refrigerant exit / entry side are aligned and connected by the same tube plate 35, and the other end portion 12L on the refrigerant return side is defined as a free end. In this state, the end 12L side is bent at the same time to form an L shape.
Here, the other end portion 12L bent in an L shape is used as a free end in the process of bending into an L shape, and the heat exchanging portion 31 located outside and the heat exchanging portion 32 located inside. This is because there is a difference in the bending (curvature and curve length) of the bent portion 12M and the end portions 12L of the heat exchange portions 31 and 32 are not aligned at the same position. That is, the end portion 12L of the outdoor heat exchanger 12 has a smaller curvature and a longer curve length as the outer heat exchanging portion 31, and therefore the outer heat exchanging portion 31 is shifted to a position deeper than the inner end portion 32L. A stepped portion is formed.

また、この室外熱交換器１２は、曲げ部１２Ｍを基準にしてＬ字状に曲げられた端部１２Ｌ側が短い直線部とされ、曲げられない側の端部１２Ｒ側が長い直線部とされており、以下、短い端部１２Ｌ側を短辺部１２Ｘと表記し、長い端部１２Ｒ側を長辺部１２Ｙと表記する。
この室外熱交換器１２は、短辺部１２Ｘを底板２１の左側（熱交換室側）の短辺２１Ｌ１に沿わせ、かつ、長辺部１２Ｙを底板２１の背面側の長辺２１Ｌ２に沿わせて底板２１上に載置される。 Further, the outdoor heat exchanger 12 has an end portion 12L side bent in an L shape with respect to the bent portion 12M as a short straight portion, and an end portion 12R side which is not bent is a long straight portion. Hereinafter, the short end portion 12L side is referred to as a short side portion 12X, and the long end portion 12R side is referred to as a long side portion 12Y.
The outdoor heat exchanger 12 has the short side portion 12X along the short side 21L1 on the left side (heat exchange chamber side) of the bottom plate 21 and the long side portion 12Y along the long side 21L2 on the back side of the bottom plate 21. And placed on the bottom plate 21.

図４に示すように、底板２１には、室外熱交換器１２が載置される略Ｌ字状の領域に渡って下方に凹む凹部２１Ｃが一体に形成されると共に、この凹部２１Ｃの底面よりも高い位置で室外熱交換器１２を下方から支持する熱交換器支持台２１Ｄが一体に形成されているため、室外熱交換器１２は、凹部２１Ｃの底面から浮いた状態で底板２１上に載置される。
すなわち、上記凹部２１Ｃは、室外熱交換器１２からのドレンを受けるドレン受けとして機能し、このドレン受けに溜まったドレンを図示せぬドレン抜き孔、或いは、ドレンホース等を介して外部に速やかに排出できるように構成されている。
また、上記熱交換器支持台２１Ｄは、複数設けられ、本構成では、室外熱交換器１２の長辺部１２Ｙの端部１２Ｒを下方から支持する第１支持台２１Ｄ１と、室外熱交換器１２の両端部１２Ｒ、１２Ｌの略中間位置を下方から支持する第２支持台２１Ｄ２と、室外熱交換器１２の短辺側の端部１２Ｌを下方から支持する第３支持台２１Ｄ３とが設けられている。 As shown in FIG. 4, the bottom plate 21 is integrally formed with a concave portion 21 </ b> C that is recessed downward over a substantially L-shaped region on which the outdoor heat exchanger 12 is placed, and from the bottom surface of the concave portion 21 </ b> C. Since the heat exchanger support 21D that supports the outdoor heat exchanger 12 from below is integrally formed at a higher position, the outdoor heat exchanger 12 is mounted on the bottom plate 21 in a state of floating from the bottom surface of the recess 21C. Placed.
That is, the concave portion 21C functions as a drain receiver that receives drain from the outdoor heat exchanger 12, and the drain accumulated in the drain receiver can be quickly and quickly discharged to the outside via a drain hole or drain hose (not shown). It is configured so that it can be discharged.
In addition, a plurality of the heat exchanger support bases 21D are provided, and in this configuration, the first support base 21D1 that supports the end 12R of the long side portion 12Y of the outdoor heat exchanger 12 from below, and the outdoor heat exchanger 12 are provided. A second support base 21D2 that supports a substantially intermediate position between the two end portions 12R and 12L from below, and a third support base 21D3 that supports the end 12L on the short side of the outdoor heat exchanger 12 from below. Yes.

この室外熱交換器１２では、長辺部１２Ｙ側の一方の端部１２Ｒを、単一の管板３５を介して機械室Ｂ側の側板２４に固定すると共に、短辺部１２Ｘ側の他方の端部１２Ｌを底板２１に固定することによって、室外熱交換器１２を底板２１上に安定固定させている。
この場合、上記単一の管板３５は、複数の熱交換部３１、３２の一方の端部を連結するため、全ての熱交換部３１、３２の一方の端部がまとめて側板２４に固定される。この側板２４は、底板２１に固定されるので、全ての熱交換部３１、３２の一方の端部が側板２４を介して底板２１に固定されることになる。
このため、室外熱交換器１２の一方の端部１２Ｒの固定強度を十分に確保できると共に、熱交換部３１、３２の一方の端部のいずれかが振動で動いてしまう事態を回避できる。
なお、この縦長の管板３５と側板２４との固定は、ねじ等の締結部材を上下に間隔を空けて複数用いて行われ、また、管板３５は、この管板３５の背面側に位置する側板２４の部分、つまり、側板２４における背面覆い部２４Ｂに固定される。また、上記管板３５をねじ等の締結部材で底板２１に固定するようにしてもよい。 In the outdoor heat exchanger 12, one end 12R on the long side 12Y side is fixed to the side plate 24 on the machine room B side through a single tube plate 35, and the other end on the short side 12X side is fixed. The outdoor heat exchanger 12 is stably fixed on the bottom plate 21 by fixing the end portion 12L to the bottom plate 21.
In this case, since the single tube plate 35 connects one end portions of the plurality of heat exchanging portions 31 and 32, one end portion of all the heat exchanging portions 31 and 32 is fixed to the side plate 24 together. Is done. Since the side plate 24 is fixed to the bottom plate 21, one end of all the heat exchange units 31 and 32 is fixed to the bottom plate 21 via the side plate 24.
For this reason, it is possible to sufficiently secure the fixing strength of the one end portion 12R of the outdoor heat exchanger 12, and it is possible to avoid a situation in which one of the end portions of the heat exchange portions 31 and 32 is moved by vibration.
The vertically long tube plate 35 and the side plate 24 are fixed by using a plurality of fastening members such as screws at intervals in the vertical direction, and the tube plate 35 is positioned on the back side of the tube plate 35. The side plate 24 is fixed to the back cover portion 24B of the side plate 24. Further, the tube plate 35 may be fixed to the bottom plate 21 with a fastening member such as a screw.

一方、室外熱交換器１２のＬ字状に曲げた他方の端部１２Ｌには、Ｌ字状に曲げた際に内外で段差部が生じるため、内外の熱交換部３１、３２を連結する管板部材（連結部材）は設けられていない。つまり、他方の端部１２Ｌ側に内外の熱交換部３１、３２を連結する管板部材を設けようとすると、管板部材の形状が複雑化して部品コストの増大等を招いてしまうから、内外の熱交換部３１、３２を連結する管板部材は設けていない。
この場合に、外側の熱交換部３２の端部３２Ｌだけに管板を取り付け、この管板を介して底板２１又は側板２３の少なくとも何れか一方側に固定したとすれば、外側の熱交換部３２の端部３２Ｌだけが固定される。しかしながら、内側の熱交換部３１は固定されておらず、しかも、この熱交換部３１が外側の熱交換部３２を内側から押圧してもいないから、外側の熱交換部３２だけを固定しただけでは、室外ユニット１０を搬送した場合に、内側の熱交換部３１が搬送時の振動で動いてしまう恐れがあった。 On the other hand, the other end portion 12L of the outdoor heat exchanger 12 bent into an L shape has a stepped portion inside and outside when bent into an L shape, so that the pipe connecting the inner and outer heat exchange portions 31, 32 A plate member (connecting member) is not provided. That is, if an attempt is made to provide a tube plate member for connecting the inner and outer heat exchange portions 31 and 32 on the other end 12L side, the shape of the tube plate member becomes complicated, leading to an increase in component costs. The tube sheet member which connects the heat exchange parts 31 and 32 is not provided.
In this case, if the tube plate is attached only to the end portion 32L of the outer heat exchanging portion 32 and fixed to at least one of the bottom plate 21 and the side plate 23 via the tube plate, the outer heat exchanging portion Only the end 32L of 32 is fixed. However, the inner heat exchanging portion 31 is not fixed, and since the heat exchanging portion 31 does not press the outer heat exchanging portion 32 from the inner side, only the outer heat exchanging portion 32 is fixed. Then, when the outdoor unit 10 is transported, the inner heat exchanging unit 31 may move due to vibration during transport.

この内側の熱交換部３１の振動を防止するために、内側の熱交換部３１にも管板を取り付けて筐体１１に固定する方法が考えられるが、管板を追加する分、熱交換部３２の組立工程が複雑化すると共に部品点数が増えてしまい、室外ユニット搬送時の振動対策のためだけに組立の複雑化や部品点数増大が生じてしまうことは望ましくない。
そこで、本実施の形態では、室外熱交換器１２のＬ字状に曲げた他方の端部１２Ｌについては、この端部１２Ｌの内側下部を外側に押圧する単一の押さえ部材５１を用いて底板２１上に固定するようにしている。 In order to prevent the vibration of the inner heat exchanging portion 31, a method of attaching a tube plate to the inner heat exchanging portion 31 and fixing it to the housing 11 is conceivable. It is not desirable that the assembling process of 32 is complicated and the number of parts is increased, and that the assembling is complicated and the number of parts is increased only for countermeasures against vibrations when the outdoor unit is transported.
Therefore, in the present embodiment, for the other end portion 12L of the outdoor heat exchanger 12 bent in an L shape, a bottom plate is used by using a single pressing member 51 that presses the inner lower portion of the end portion 12L outward. 21 is fixed.

図５は、押さえ部材５１で室外熱交換器１２の端部１２Ｌを固定した状態を示す斜視図であり、図６は押さえ部材５１を周辺構成と共に上方から見た図であり、図７は、押さえ部材５１の斜視図である。
押さえ部材５１は、図５および図６に示すように、底板２１上に載置された室外熱交換器１２における内側の熱交換部３１の端部３１Ｌと、室外ユニット１０における底板２１前側から立ち上がる立ち上がり縁２１Ｂとの間の空間部ＳＰ内に嵌合する小型部品に形成されている。
詳述すると、この押さえ部材５１は、図７に示すように、上方に立ち上がる第１板部（固定部）５２と、この第１板部５２と室外ユニット１０の前後方向（略水平方向）に間隔を空けて上方に立ち上がる第２板部（当接板部）５３と、第１板部５２と第２板部５３とをつなぐ第３板部（つなぎ部）５４とを備えて構成され、これらは金属板等の剛性を有する単一の板部材を屈曲形成することによって一体に形成される。そして、この押さえ部材５１は、第１板部５２を底板２１の立ち上がり縁２１Ｂ側に向けると共に、第３板部５４を熱交換部３１の端部３１Ｌ側に向けることによって、上記空間部ＳＰに挿入される。 FIG. 5 is a perspective view showing a state in which the end 12L of the outdoor heat exchanger 12 is fixed by the holding member 51, FIG. 6 is a view of the holding member 51 as viewed from above together with the peripheral configuration, and FIG. 3 is a perspective view of a pressing member 51. FIG.
As shown in FIGS. 5 and 6, the pressing member 51 rises from the end portion 31 </ b> L of the inner heat exchanging portion 31 in the outdoor heat exchanger 12 placed on the bottom plate 21 and the front side of the bottom plate 21 in the outdoor unit 10. It is formed as a small component that fits in the space SP between the rising edge 21B.
More specifically, as shown in FIG. 7, the pressing member 51 includes a first plate portion (fixed portion) 52 that rises upward, and a front-rear direction (substantially horizontal direction) of the first plate portion 52 and the outdoor unit 10. A second plate portion (contact plate portion) 53 that rises upward with an interval, and a third plate portion (connection portion) 54 that connects the first plate portion 52 and the second plate portion 53, These are integrally formed by bending a single plate member having rigidity such as a metal plate. The pressing member 51 has the first plate portion 52 directed toward the rising edge 21B of the bottom plate 21 and the third plate portion 54 directed toward the end portion 31L of the heat exchanging portion 31 to thereby form the space SP. Inserted.

第１板部５２は、底板２１の立ち上がり縁２１Ｂに形成された不図示の貫通孔に連通する貫通孔５２Ａを有しており、連通した貫通孔に通された雄ねじ６１（図６参照）およびナット６２（図６参照）により立ち上がり縁２１Ｂに固定される。より具体的には、立ち上がり縁２１Ｂには、図６に示すように、底板２１上に載置された熱交換部３１の端部３１Ｌ側に向かって背面側に突出する突出部２１Ｂ１が一体に形成されており、この突出部２１Ｂ１に第１板部５２が固定されるようになっている。
このように立ち上がり縁２１Ｂの一部を突出させた突出部２１Ｂ１を形成すれば、立ち上がり縁２１Ｂを単純な平板形状にした場合よりも強度が向上するので、この強度が向上した突出部２１Ｂ１に押さえ部材５１を固定することで、底板２１における押さえ部材５１の支持力を向上することができる。 The first plate portion 52 has a through hole 52A that communicates with a through hole (not shown) formed in the rising edge 21B of the bottom plate 21, and a male screw 61 (see FIG. 6) passed through the communicated through hole and The nut 62 (see FIG. 6) is fixed to the rising edge 21B. More specifically, as shown in FIG. 6, the rising edge 21 </ b> B is integrally provided with a protruding portion 21 </ b> B <b> 1 that protrudes toward the back side toward the end portion 31 </ b> L side of the heat exchanging portion 31 placed on the bottom plate 21. The first plate portion 52 is fixed to the protruding portion 21B1.
If the protruding portion 21B1 in which a part of the rising edge 21B protrudes is formed in this way, the strength is improved as compared with the case where the rising edge 21B has a simple flat plate shape. By fixing the member 51, the supporting force of the pressing member 51 on the bottom plate 21 can be improved.

また、第２板部５３は、第１板部５２が底板２１の立ち上がり縁２１Ｂに固定された場合に、内側の熱交換部３１の内側下部を押圧する押圧部として機能する。より具体的には、第２板部５３は、熱交換部３１の端部３１Ｌ下部に当接して室外ユニット１０の背面側に押圧する端部押圧部５３Ａと、この端部押圧部５３Ａから上面視で略９０度の角度で屈曲し、熱交換部３１の端部３１Ｌ近傍の内側下部に当接して室外ユニット１０の左側に押圧する内側下部押圧部５３Ｂとを備える。これによって、押さえ部材５１は、底板２１に固定されると、固定部（突出部２１Ｂ１）を基準にして内側の熱交換部３１の端部３１Ｌを室外ユニット１０の背面側および左側に押圧する。   In addition, the second plate portion 53 functions as a pressing portion that presses the inner lower portion of the inner heat exchanging portion 31 when the first plate portion 52 is fixed to the rising edge 21 </ b> B of the bottom plate 21. More specifically, the second plate portion 53 includes an end pressing portion 53A that contacts the lower portion of the end portion 31L of the heat exchanging portion 31 and presses against the back side of the outdoor unit 10, and an upper surface from the end pressing portion 53A. An inner lower pressing portion 53B that is bent at an angle of about 90 degrees as viewed and contacts the inner lower portion in the vicinity of the end portion 31L of the heat exchanging portion 31 and presses the left side of the outdoor unit 10 is provided. Thus, when the pressing member 51 is fixed to the bottom plate 21, the end portion 31 </ b> L of the inner heat exchanging portion 31 is pressed to the back side and the left side of the outdoor unit 10 with reference to the fixing portion (projecting portion 21 </ b> B <b> 1).

この場合、図６に示すように、内側の熱交換部３１における室外ユニット１０の背面側には、室外熱交換器１２の曲げ部１２Ｍおよび長辺部１２Ｙにおける外側の熱交換部３２が位置する。このため、内側の熱交換部３１の端部３１Ｌを室外ユニット１０の背面側に押圧すれば、曲げ部１２Ｍおよび長辺部１２Ｙにおいて内側の熱交換部３１が外側の熱交換部３２を押圧する。
また、図６に示すように、内側の熱交換部３１における室外ユニット１０の左側にも、室外熱交換器１２の短辺部１２Ｘおよび曲げ部１２Ｍにおける外側の熱交換部３２が位置するので、内側の熱交換部３１の端部３１Ｌを室外ユニット１０の左側に押圧すれば、短辺部１２Ｘおよび曲げ部１２Ｍにおいても内側の熱交換部３１が外側の熱交換部３２を押圧する。
すなわち、押さえ部材５１で内側の熱交換部３１の端部３１Ｌを室外ユニット１０の背面側および左側に押圧することによって、短辺部１２Ｘから曲げ部１２Ｍを経由した長辺部１２Ｙにおいて内側の熱交換部３１が外側の熱交換部３２を押圧し、互いに密着させることができ、他方の端部１２Ｌ側で熱交換部３１、３２のいずれかだけが搬送時の振動で動いてしまうのを回避することができる。 In this case, as shown in FIG. 6, the bent portion 12M of the outdoor heat exchanger 12 and the outer heat exchange portion 32 in the long side portion 12Y are located on the back side of the outdoor unit 10 in the inner heat exchange portion 31. . For this reason, if the end portion 31L of the inner heat exchanging portion 31 is pressed against the back side of the outdoor unit 10, the inner heat exchanging portion 31 presses the outer heat exchanging portion 32 at the bent portion 12M and the long side portion 12Y. .
Further, as shown in FIG. 6, the short side portion 12X of the outdoor heat exchanger 12 and the outer heat exchange portion 32 in the bent portion 12M are located on the left side of the outdoor unit 10 in the inner heat exchange portion 31, If the end portion 31L of the inner heat exchanging portion 31 is pressed to the left side of the outdoor unit 10, the inner heat exchanging portion 31 also presses the outer heat exchanging portion 32 in the short side portion 12X and the bent portion 12M.
That is, by pressing the end portion 31L of the inner heat exchanging portion 31 to the back side and the left side of the outdoor unit 10 with the holding member 51, the inner side heat in the long side portion 12Y from the short side portion 12X via the bent portion 12M. The exchanging part 31 can press the outer heat exchanging part 32 to be in close contact with each other, and avoids that only one of the heat exchanging parts 31 and 32 is moved by vibration during conveyance on the other end 12L side. can do.

また、第２板部５３の端部押圧部５３Ａには、内側の熱交換部３１の最下部に設けられたＵベンド管３３が入る支持溝部５５が形成される。この支持溝部５３Ｃは、Ｕベンド管３３が入る溝部の周囲に沿って延びるリブ５５Ａが設けられ、このリブ５５ＡによりＵベンド管３３を支持すると共に、この端部押圧部５３Ａの強度が補強される。
さらに、押さえ部材５１には、第１板部５２、第３板部５４および第２板部５３に渡って連続するリブ５６が一体に設けられ、このリブ５６により押さえ部材５１の各部が補強されて押さえ部材５１全体の強度が補強される。 Further, the end pressing portion 53 </ b> A of the second plate portion 53 is formed with a support groove portion 55 into which the U-bend pipe 33 provided at the lowermost portion of the inner heat exchanging portion 31 is inserted. The support groove 53C is provided with a rib 55A extending along the periphery of the groove into which the U-bend pipe 33 is inserted. The rib 55A supports the U-bend pipe 33 and reinforces the strength of the end pressing part 53A. .
Further, the pressing member 51 is integrally provided with a rib 56 that continues across the first plate portion 52, the third plate portion 54, and the second plate portion 53, and each portion of the pressing member 51 is reinforced by the rib 56. Thus, the strength of the entire pressing member 51 is reinforced.

また、本実施の形態では、他方の端部１２Ｌ側で内側の熱交換部３１が外側の熱交換部３２を押圧するので、外側の熱交換部３２が、底板２１の立ち上がり縁２１Ｂ（底板２１の側面）に当接し、この立ち上がり縁２１Ｂと押さえ部材５１との間に、内外の熱交換部３１、３２を挟持する。
より具体的には、立ち上がり縁２１Ｂには、室外ユニット１０の背面から内側（前面側）に突出して長辺部１２Ｙにおける外側の熱交換部３１が当接する背面側当接部７１が設けられると共に、室外ユニット１０の左側面側から内側に突出して短辺部１２Ｘにおける外側の熱交換部３１が当接する左側面側当接部７２が設けられ、これら当接部７１、７２により外側の熱交換部３２の背面側および左側面側への移動を規制する。
すなわち、本構成では、押さえ部材３１が内側の熱交換部３１を外側の熱交換部３２に向かって押圧するので、外側の熱交換部３２にも背面側および左側面側への押圧力が作用し、この押圧力で外側の熱交換部３２の背面側および左側面側が背面側当接部７１および左側面側当接部７２に当接する。 Further, in the present embodiment, the inner heat exchanging portion 31 presses the outer heat exchanging portion 32 on the other end 12L side, so that the outer heat exchanging portion 32 has the rising edge 21B (bottom plate 21) of the bottom plate 21. The inner and outer heat exchanging portions 31 and 32 are sandwiched between the rising edge 21 </ b> B and the pressing member 51.
More specifically, the rising edge 21B is provided with a back-side contact portion 71 that protrudes inward (front side) from the back surface of the outdoor unit 10 and contacts the outer heat exchanging portion 31 in the long side portion 12Y. A left side abutting portion 72 that protrudes inward from the left side surface of the outdoor unit 10 and abuts against the outer heat exchanging portion 31 in the short side portion 12X is provided. The movement of the part 32 to the back side and the left side is restricted.
In other words, in this configuration, the pressing member 31 presses the inner heat exchanging portion 31 toward the outer heat exchanging portion 32, so that the pressing force to the back side and the left side also acts on the outer heat exchanging portion 32. Then, with this pressing force, the back surface side and the left side surface side of the outer heat exchanging portion 32 abut on the back surface side contact portion 71 and the left side surface side contact portion 72.

従って、背面側当接部７１と押さえ部材５１との間、および、上記左側面側当接部７２と押さえ部材５１との間に、内外の熱交換部３１、３２を挟持させることができ、他方の端部１２Ｌ側における内外の熱交換部３１、３２の支持力を十分に確保できる。
この場合、外側の熱交換部３２が当接する背面側当接部７１および左側面側当接部７２を、立ち上がり縁２１Ｂを部分的に内側に突出させて形成するので、これら当接部７１、７２の強度を向上でき、室外熱交換器１２の支持力を向上することができる。
このように、室外熱交換器１２における他方の端部１２Ｌの内側下部を押さえ部材７１で外側に押圧して底板２１上に固定すれば、他方の端部１２Ｌの上側に要求される支持力は小さくて済む。このため、本構成では、図２に示すように、他方の端部１２Ｌにおける押さえ部材５１上方では、内外の熱交換部３１、３２間を左右のＵベンド管３３に通した結束バンド６５でバンド止めした簡易な連結構造で十分な支持力を確保することができる。
この場合、内外の熱交換部３１、３２が、他方の端部１２Ｌ側でバンド止めされ、一方の端部１２Ｌ側で管板３５を介して連結されるので、押さえ部材５１取り付け前においても、内外の熱交換部３１、３２が別々にならず、室外熱交換器１２の取り付け作業や取り外し作業を容易にすることができる。 Therefore, the inner and outer heat exchanging portions 31 and 32 can be sandwiched between the back surface side contact portion 71 and the pressing member 51 and between the left side surface contact portion 72 and the pressing member 51. Sufficient support force for the inner and outer heat exchanging portions 31 and 32 on the other end 12L side can be secured.
In this case, the back surface side contact portion 71 and the left side surface contact portion 72 with which the outer heat exchanging portion 32 abuts are formed with the rising edge 21B partially protruding inward. The strength of 72 can be improved, and the supporting force of the outdoor heat exchanger 12 can be improved.
Thus, if the inner lower part of the other end 12L of the outdoor heat exchanger 12 is pressed outward by the pressing member 71 and fixed on the bottom plate 21, the supporting force required on the upper side of the other end 12L is It's small. For this reason, in this configuration, as shown in FIG. 2, a band is formed by a binding band 65 that passes between the inner and outer heat exchanging portions 31 and 32 through the left and right U-bend pipes 33 above the pressing member 51 at the other end 12L. Sufficient support force can be ensured with the simple connection structure stopped.
In this case, the inner and outer heat exchanging portions 31 and 32 are band-stopped on the other end portion 12L side and connected via the tube plate 35 on the one end portion 12L side, so even before the pressing member 51 is attached, The inner and outer heat exchanging portions 31 and 32 are not separated, and the attaching and removing operations of the outdoor heat exchanger 12 can be facilitated.

以上説明したように、本実施の形態では、室外熱交換器１２の一方の端部１２Ｒを内外の熱交換部３１、３２を連結する管板３５を介して底板２１上に固定すると共に、Ｌ字状に曲げた他方の端部１２Ｌの内側下部を外側に押圧するように押さえ部材５１で底板２１上に固定したので、室外熱交換器１２の一方の端部１２Ｒだけでなく、他方の端部１２Ｌにおいても内外の熱交換部３１、３２を密着して固定することができる。従って、内外の熱交換部３１、３２が別々に動いてしまう事態を回避でき、内外の熱交換部３１、３２を別々に固定する管板部材を使用することなく、簡易な構成で、室外ユニット搬送時における内側の熱交換部３１の移動を規制することができる。
しかも、本構成では、室外熱交換器１２の他方の端部１２Ｌを押さえ部材５１で外側に押圧し、この押さえ部材５１と室外ユニット１０の側板との間に挟持するようにしたので、内外の熱交換部３１、３２の密着度および底板２１上への支持力をより向上させることができる。 As described above, in the present embodiment, one end portion 12R of the outdoor heat exchanger 12 is fixed on the bottom plate 21 via the tube plate 35 connecting the inner and outer heat exchange portions 31 and 32, and L Since it fixed on the baseplate 21 with the pressing member 51 so that the inner lower part of the other end part 12L bent in the shape of a letter may be pressed outside, not only one end part 12R of the outdoor heat exchanger 12 but also the other end Also in the part 12L, the inner and outer heat exchange parts 31 and 32 can be closely fixed. Accordingly, it is possible to avoid the situation where the inner and outer heat exchanging parts 31 and 32 move separately, and without using a tube plate member for separately fixing the inner and outer heat exchanging parts 31 and 32, the outdoor unit The movement of the inner heat exchanging portion 31 during conveyance can be restricted.
In addition, in this configuration, the other end 12L of the outdoor heat exchanger 12 is pressed outward by the pressing member 51, and is sandwiched between the pressing member 51 and the side plate of the outdoor unit 10. The degree of adhesion of the heat exchange units 31 and 32 and the supporting force on the bottom plate 21 can be further improved.

また、本構成では、室外熱交換器１２の他方の端部１２Ｌで複数の熱交換部３１、３２間をバンド止めするので、他方の端部１２Ｌについては押さえ部材５１と結束バンド６５だけで固定され、室外熱交換器１２の取り付けや取り外しの作業が容易である。
また、押さえ部材５１が内側の熱交換部３１のＵベンド管３３を支持する支持溝部５５を有するので、Ｕベンド管３３を支持する分、内側の熱交換部３１の内側下部をより安定して支持することができ、熱交換部３１の内側下部を安定して外側に押圧することができる。また、押さえ部材５１が、底板２１に固定される第１板部（固定部）５２と、熱交換部３１の内側下部に当接すると共に上記支持溝部５５を有する第２板部（当接部）５２とを一体に備えるので、部品点数の増大を回避でき、かつ、第１板部５２と第２板部５３との寸法精度を確保し易い。 Further, in this configuration, the other end portion 12L of the outdoor heat exchanger 12 is band-stopped between the plurality of heat exchanging portions 31 and 32, so that the other end portion 12L is fixed only by the pressing member 51 and the binding band 65. Therefore, the work of attaching and removing the outdoor heat exchanger 12 is easy.
Further, since the holding member 51 has the support groove portion 55 that supports the U bend pipe 33 of the inner heat exchanging portion 31, the inner lower portion of the inner heat exchanging portion 31 is more stably supported by the amount of support of the U bend pipe 33. It can support, and the inner lower part of the heat exchange part 31 can be stably pressed outside. The pressing member 51 is in contact with the first plate portion (fixed portion) 52 fixed to the bottom plate 21 and the inner lower portion of the heat exchanging portion 31 and the second plate portion (contact portion) having the support groove portion 55. 52 is integrally provided, an increase in the number of parts can be avoided, and the dimensional accuracy of the first plate portion 52 and the second plate portion 53 can be easily ensured.
