例えば特許文献１に開示されているように、空気調和機の室外機は、室外機本体の底部を構成する底板の上部に熱交換器を設ける構成となっている。空気調和機の室外機において、底板は、角部を有するほぼ矩形状に構成され、これに対して、熱交換器は、途中部分が円弧状に曲げられた曲げ部を有する構成となっている。そして、熱交換器は、曲げ部を底板の角部に対向させた状態で配置される。そのため、底板の角部と熱交換器の曲げ部との間に隙間が形成される構造となっている。 For example, as disclosed in Patent Literature 1, an outdoor unit of an air conditioner has a configuration in which a heat exchanger is provided on an upper portion of a bottom plate forming a bottom portion of an outdoor unit main body. In an outdoor unit of an air conditioner, the bottom plate is configured in a substantially rectangular shape with corners, whereas the heat exchanger has a curved portion that is curved in an arc shape in the middle. . The heat exchanger is arranged with the bent portion facing the corner of the bottom plate. Therefore, the structure is such that a gap is formed between the corner of the bottom plate and the bent portion of the heat exchanger.

Perspective view schematically showing the state in which it is arranged 本実施形態に係る断熱材の構成例を概略的に示す図The figure which shows roughly the structural example of the heat insulating material which concerns on this embodiment.

以下、空気調和機の室外機に係る一実施形態について図面を参照しながら説明する。図１に例示する空気調和機の室外機１０は、屋内に設けられる図示しない室内機とともに空気調和機を構成するものであって、その外郭を構成するほぼ矩形状の室外機本体１１の底部が底板１２により構成されている。底板１２は、底面が浅いほぼ矩形の容器状をなしている。底板１２の上部には、図示しない圧縮機、アキュームレータ、送風ファンなどが設けられている。また、底板１２の上部には、熱交換器１３が設けられている。 An embodiment of an outdoor unit for an air conditioner will be described below with reference to the drawings. An outdoor unit 10 of an air conditioner illustrated in FIG. 1 constitutes an air conditioner together with an indoor unit (not shown) installed indoors, and the bottom of a substantially rectangular outdoor unit main body 11 that constitutes the outer shell is It is composed of a bottom plate 12 . The bottom plate 12 has a substantially rectangular container shape with a shallow bottom. A compressor, an accumulator, a blower fan, and the like (not shown) are provided on the upper portion of the bottom plate 12 . A heat exchanger 13 is provided on the upper portion of the bottom plate 12 .

熱交換器１３は、図示しない圧縮機やアキュームレータなどとともに周知の冷凍サイクルを構築している。そして、熱交換器１３は、図示しない送風ファンによって送風される空気と熱交換する。熱交換器１３は、室外機本体１１の後面に沿う後面側熱交換部１３Ａと室外機本体１１の側面に沿う側面側熱交換部１３Ｂとの間に曲げ部１３Ｃを有している。曲げ部１３Ｃは、後面側熱交換部１３Ａと側面側熱交換部１３Ｂとを連結する滑らかな円弧状の曲げ部となっている。 The heat exchanger 13 constructs a well-known refrigeration cycle together with a compressor and an accumulator (not shown). The heat exchanger 13 exchanges heat with air blown by a blower fan (not shown). The heat exchanger 13 has a bent portion 13C between a rear heat exchange portion 13A along the rear surface of the outdoor unit main body 11 and a side heat exchange portion 13B along the side surface of the outdoor unit main body 11 . The bent portion 13C is a smooth arc-shaped bent portion that connects the rear heat exchange portion 13A and the side heat exchange portion 13B.

図２に例示するように、底板１２は、その縁部が上方に折り曲げられており、これにより壁部１２Ａが構成されている。また、底板１２の角部１２Ｂにおいて、壁部１２Ａは、熱交換器１３の曲げ部１３Ｃの曲げ角度よりも直角に近い形状となっている。そして、底板１２の上部において、熱交換器１３は、曲げ部１３Ｃを底板１２の角部１２Ｂに対向させた状態で配置される。そのため、底板１２の角部１２Ｂと熱交換器１３の曲げ部１３Ｃとの間に隙間Ｇが形成される構造となっている。なお、底板１２は、隙間Ｇの底部となる部分に、当該底板１２を貫通する水抜き孔１２Ｃを備えている。 As illustrated in FIG. 2, the edge of the bottom plate 12 is bent upward to form a wall portion 12A. At the corner 12B of the bottom plate 12, the wall 12A has a shape that is closer to a right angle than the bending angle of the bent portion 13C of the heat exchanger 13. As shown in FIG. The heat exchanger 13 is arranged on the upper portion of the bottom plate 12 with the bent portion 13C facing the corner portion 12B of the bottom plate 12 . Therefore, the structure is such that a gap G is formed between the corner portion 12B of the bottom plate 12 and the bent portion 13C of the heat exchanger 13 . The bottom plate 12 has a drain hole 12C penetrating through the bottom plate 12 at the bottom of the gap G. As shown in FIG.

そして、図３に例示するように、室外機１０は、この隙間Ｇに断熱材１４を備えた構成となっている。断熱材１４は、例えば、発泡スチロールや発泡ウレタンなどの断熱材料により構成されている。 Then, as illustrated in FIG. 3, the outdoor unit 10 has a configuration in which a heat insulating material 14 is provided in the gap G. As shown in FIG. The heat insulating material 14 is made of a heat insulating material such as polystyrene foam or urethane foam.

図４に例示するように、断熱材１４は、外縁部１４Ａおよび内縁部１４Ｂを備えている。外縁部１４Ａは、底板１２の角部１２Ｂにおける壁部１２Ａの形状に応じた直角に近い形状となっている。一方、内縁部１４Ｂは、熱交換器１３の曲げ部１３Ｃの形状に応じた滑らかな円弧状の形状となっている。さらに、断熱材１４は、凹部１４Ｃを備えている。この場合、凹部１４Ｃは、内縁部１４Ｂのほぼ中央部に設けられており、断熱材１４が隙間Ｇ内に取り付けられた状態において、熱交換器１３の曲げ部１３Ｃのほぼ中央部に対向するようになっている。また、凹部１４Ｃは、断熱材１４が隙間Ｇ内に取り付けられた状態において、底板１２の水抜き孔１２Ｃの上方に位置するようになっている。また、この場合、凹部１４Ｃは、矩形状に切り欠かれた凹部となっている。 As illustrated in FIG. 4, the thermal insulator 14 has an outer edge 14A and an inner edge 14B. The outer edge portion 14A has a shape close to a right angle corresponding to the shape of the wall portion 12A at the corner portion 12B of the bottom plate 12 . On the other hand, the inner edge portion 14B has a smooth arcuate shape corresponding to the shape of the bent portion 13C of the heat exchanger 13 . Furthermore, the heat insulator 14 has a recess 14C. In this case, the recessed portion 14C is provided substantially at the center of the inner edge portion 14B so as to face substantially the center portion of the bent portion 13C of the heat exchanger 13 when the heat insulating material 14 is attached in the gap G. It has become. Further, the recessed portion 14C is positioned above the drain hole 12C of the bottom plate 12 when the heat insulating material 14 is installed in the gap G. As shown in FIG. Further, in this case, the recess 14C is a rectangular recess.

以上に説明した空気調和機の室外機１０によれば、底板１２の角部１２Ｂと熱交換器１３の曲げ部１３Ｃとの間に形成される隙間Ｇに断熱材１４を備えている。この構成によれば、底板１２の角部１２Ｂと熱交換器１３の曲げ部１３Ｃとの間の隙間Ｇにおける凍り付きを、断熱材１４による断熱作用によって抑制することができる。よって、隙間Ｇにおける凍り付きが熱交換器１３に悪影響を及ぼすことを回避することができる。 According to the outdoor unit 10 of the air conditioner described above, the heat insulating material 14 is provided in the gap G formed between the corner portion 12B of the bottom plate 12 and the bent portion 13C of the heat exchanger 13 . According to this configuration, freezing in the gap G between the corner portion 12B of the bottom plate 12 and the bent portion 13C of the heat exchanger 13 can be suppressed by the heat insulation effect of the heat insulating material 14 . Therefore, it is possible to prevent the heat exchanger 13 from being adversely affected by freezing in the gap G.

また、室外機１０によれば、断熱材１４は、凹部１４Ｃを有している。この構成によれば、断熱材１４の上部に存在する水を凹部１４Ｃおよび水抜き孔１２Ｃを通して底板１２の下方に効率良く排出することができ、当該隙間Ｇ内における凍り付きを一層効果的に抑制することができる。 Further, according to the outdoor unit 10, the heat insulating material 14 has the recess 14C. According to this configuration, the water present in the upper portion of the heat insulating material 14 can be efficiently discharged below the bottom plate 12 through the recess 14C and the drain hole 12C, thereby further effectively suppressing freezing in the gap G. be able to.

なお、本実施形態は、上述した一実施形態に限定されるものではなく、その要旨を逸脱しない範囲で種々の変更や拡張を行うことができる。例えば、断熱材１４に形成する凹部１４Ｃの形状、大きさ、位置、数などは適宜変更して実施することができる。また、断熱材１４は、凹部１４Ｃを備えない構成としてもよい。また、断熱材１４の形状や大きさなどは、隙間Ｇの形状や大きさなどに応じて適宜変更して実施することができる。また、本実施形態は、水が凍り付くような寒冷地において用いられる室外機に好適であるが、水が凍り付かない環境において用いられる室外機にも適用することができる。 The present embodiment is not limited to the one embodiment described above, and various modifications and extensions can be made without departing from the scope of the present embodiment. For example, the shape, size, position, number, etc. of the recesses 14C formed in the heat insulating material 14 can be changed as appropriate. Moreover, the heat insulating material 14 may be configured without the concave portion 14C. Further, the shape and size of the heat insulating material 14 can be appropriately changed according to the shape and size of the gap G. In addition, although the present embodiment is suitable for outdoor units used in cold regions where water freezes, it can also be applied to outdoor units used in environments where water does not freeze.
