Embodiment 1 FIG.
FIG. 1 is an exploded perspective view of a housing of an outdoor unit 1 for an air conditioner according to Embodiment 1 of the present invention. In FIG. 1, the direction of arrow a is the front.
As shown in FIG. 1, the outdoor unit 1 forms a housing with a top plate 10, a left side plate 11, a right side plate 12, a front plate 13, a back plate 14, and a bottom plate 15. The top plate 10, the left side plate 11, the right side plate 12, the front plate 13, the back plate 14, and the bottom plate 15 are made of sheet metal, and the top plate 10 and the left side plate 11, the right side plate 12, the bottom plate 15 and the left side plate. 11 and the right side surface plate 12 are joined by screwing at the side surfaces of the four corners of the housing. The top plate 10, the front plate 13, and the back plate 14, and the bottom plate 15, the front plate 13 and the back plate 14 are also joined together by screwing as appropriate.
　図２は、図１のＡに示す部分を拡大した図である。
　図２に示すように、天板１０には、天板１０と一体形成されたネジ留め部１６が設けられ、ネジ留め部１６を介して、室外機１の天板１０と左側面板１１、天板１０と前面板１３、天板１０と背面板１４とがそれぞれネジ留めされることで接合される。
　ネジ留め部１６は、天板１０の端部を底板１５側に直角に折り曲げ、底板１５と水平になるようにさらに直角に折り曲げることによって構成される。つまり、直角に折り曲げられたネジ留め部１６により、筺体の角は窪んだ形状となっている。
　なお、図２において、ネジ留め部１６は、天板１０と一体形成されることとしているが、これに限らず、左側面板１１と一体形成され、左側面板１１の端部を天板１０側に直角に折り曲げ、天板１０と垂直になるようにさらに直角に折り曲げることによって構成されるようにしてもよい。

Here, the outdoor unit 1 installed on the side to be stacked, that is, the lower outdoor unit 1 is referred to as the outdoor unit 1 on the lower side, and the outdoor unit 1 installed on the side to be stacked, that is, the upper side.
When the same outdoor unit 1 is stacked on the outdoor unit 1, as shown in FIG. 5, as shown in FIG. 5, a laminated resin cover 20 is provided so as to cover the joint between the lower outdoor unit 1 and the upper outdoor unit 1. Install.
FIG. 6 is an enlarged view of the portion indicated by C in FIG. 5 with the resin cover 20 removed during lamination.
The lower-stage outdoor unit 1 and the upper-stage outdoor unit 1 are fixed by a stacking metal fixture 21.
The stacking metal fitting 21 is formed into a two-stage convex shape by bending a sheet metal at six right angles. As shown in FIG. 6, the central convex portion has the lower outdoor unit 1 and the upper outdoor unit. It acts as a spacer with the machine 1.
The stacking brackets 21 are screwed to the lower outdoor unit 1 and the upper outdoor unit 1, respectively, so that the outdoor units 1 stacked one above the other are fixed.
　図７は、積層用金具２１の取り付け例を示す図である。なお、図７は、図６に示した部分を斜めから見た図である。
　積層用金具２１は、直角に折れ曲げた金具の端が、下段の室外機１の天板１０および上段の室外機１の底板１５と平行になるようにして、中央の凸部が下段の室外機１の天板および上段の室外機１の底板１５に挟まれるように、つまり、直角に折れ曲がった金具の端が外側（室外機１の中央と反対側）を向くように取り付けられる。積層用金具２１は、下段の室外機１の天板１０の側面と接する部分、および、上段の室外機１の底板１５の側面と接する部分でネジ留めされる。なお、ここでは、図７に示すように、積層用金具２１は、下段の室外機１の天板１０の側面および上段の室外機１の底板１５の側面と接する位置で３箇所ネジ留めするものとしたが、これに限らず、２箇所以下としても４箇所以上してもよい。また、室外機１の天板１０または底板１５の側面とネジ留めするのではなく、ネジ留め部１６を介して側面板とネジ留めされるなど、ネジ留め位置については適宜設定すればよい。

The stacking metal fitting 21 is bent at a right angle so that the end of the metal fitting is parallel to the top plate 10 of the lower outdoor unit 1 and the bottom plate 15 of the upper outdoor unit 1, and the center convex portion is the lower outdoor unit. It is attached so as to be sandwiched between the top plate of the machine 1 and the bottom plate 15 of the upper outdoor unit 1, that is, the end of the bracket bent at a right angle faces the outside (the side opposite to the center of the outdoor unit 1). The stacking metal fixture 21 is screwed at a portion in contact with the side surface of the top plate 10 of the lower outdoor unit 1 and a portion in contact with the side surface of the bottom plate 15 of the upper outdoor unit 1. Here, as shown in FIG. 7, the stacking metal fitting 21 is screwed at three positions at positions in contact with the side surface of the top plate 10 of the lower outdoor unit 1 and the side surface of the bottom plate 15 of the upper outdoor unit 1. However, the present invention is not limited to this, and may be two or less or four or more. Moreover, what is necessary is just to set suitably about the screwing position, such as not screwing with the side surface of the top plate 10 or the baseplate 15 of the outdoor unit 1, but screwing with a side plate via the screwing part 16. FIG.
Moreover, the metal fitting 21 for lamination | stacking is good also as a U shape, without providing a convex part. In that case, the vertical side of the U-shape of the stacking bracket 21 is between the top plate 10 of the lower outdoor unit 1 and the bottom plate 15 of the upper outdoor unit 1 when the outdoor unit 1 is stacked up and down. Make the space as long as possible.
　図８は、室外機１を積層した場合に、接合部をカバーする積層時樹脂カバー２０の斜視図である。
　積層時樹脂カバー２０は、合成樹脂で形成されており、図８に示すように、爪１９を有し、室外機１の天板１０および底板１５の側面のネジ留め部１６の、積層用金具２１と重なる位置に設けられた切り欠き穴１８に爪１９をひっかけることで取り付けられる。なお、切り欠き穴１８は、積層用金具２１にも、室外機１に設けられた切り欠き穴１８まで貫通するように設けられている。 FIG. 8 is a perspective view of the laminated resin cover 20 that covers the joint when the outdoor unit 1 is laminated.
The laminated resin cover 20 is formed of a synthetic resin, and has a claw 19 as shown in FIG. 8, and a laminated metal fitting for the screwing portions 16 on the side surfaces of the top plate 10 and the bottom plate 15 of the outdoor unit 1. It attaches by hooking the nail | claw 19 in the notch hole 18 provided in the position which overlaps with 21. FIG. The notch hole 18 is also provided in the stacking metal fitting 21 so as to penetrate to the notch hole 18 provided in the outdoor unit 1.
　なお、図７，図８において、切り欠き穴１８および爪１９はそれぞれ２個としたが、これに限らず、１箇所でも３箇所以上でも、適宜設定可能である。また、図７，図８では、天板１０および底板１５の側面のネジ留め部１６の、積層用金具２１と重なる位置で積層時樹脂カバー２０がひっかけられるように切り欠き穴１８および爪１９をそれぞれ設ける構成としたが、これに限らず、ネジ留め部１６が左側面板１１と接する面に切り欠き穴１８を設け、その切り欠き穴１８と対向する積層時樹脂カバー２０の面に爪１９を設けて、積層時樹脂カバー２０が取りつけられる構成としてもよいし、その他の取り付け方法を用いても構わない。

Similarly, the laminated resin cover 20 is also formed at the upper left corner when viewed from the front of the lower outdoor unit 1. It is attached to the side of the outdoor unit 1.
　また、ここでは、２台の室外機１を上下に積層する場合について説明したが、さらに室外機１を３台以上積層する場合においても同様である。
　以上のように、この実施の形態１によれば、樹脂カバー１７が室外機１の四隅の側面に取り付けられることで、接合部のネジが隠されるため、ネジの錆びを防ぐことができる。また、樹脂カバー１７がネジを覆うことで、外部からネジが見えず、凹凸の少ない平面を形成することで美観が向上する。また、ネジ留めの場所を筺体の四隅に集中させたので、組み立て性を向上させることができる。また、樹脂カバー１７で四隅が覆われていることで、人が接触した際の安全性をより高めることができる。また、室外機１を積層する場合においては、積層時樹脂カバー２０を用いることで、樹脂カバー１７同様、ネジの錆びを防ぐことができ、凹凸の少ない平面を形成するので、美観が向上する。 Although the case where two outdoor units 1 are stacked one above the other has been described here, the same applies to the case where three or more outdoor units 1 are stacked.
As described above, according to the first embodiment, since the resin cover 17 is attached to the side surfaces of the four corners of the outdoor unit 1, the screw at the joint is hidden, so that the screw can be prevented from being rusted. Further, since the resin cover 17 covers the screws, the screws cannot be seen from the outside, and the appearance is improved by forming a flat surface with less unevenness. Moreover, since the screwing locations are concentrated at the four corners of the housing, the assemblability can be improved. In addition, since the four corners are covered with the resin cover 17, it is possible to further improve safety when a person comes into contact. Moreover, when laminating | stacking the outdoor unit 1, by using the resin cover 20 at the time of lamination | stacking, the rust of a screw | thread can be prevented similarly to the resin cover 17, and since a flat surface with few unevenness | corrugations is formed, aesthetics improve.
