ヒンジ結合部５は、図２及び図３に示すように、第１カバー部４０及び第２カバー部４１と共に一体成形されており、柔軟性のある合成樹脂で構成されている。ヒンジ結合部５は、第１カバー部４０の下端部と、第２カバー部４１の上端部と連結するものであり、図６〜図８に示すように、右側面パネル１１に取り付けられている第１カバー部４０に対して右側面パネル１１から取り外された第２カバー部４１を回動自在に連結するものである。ヒンジ結合部５は、第１カバー部４０及び第２カバー部４１の幅方向における略中央部分にのみ設けている。これは、第１カバー部４０に対して、第２カバー部４１を回動させやすくするためである。但し、ヒンジ結合部５は、間隔をあけて並列させて配置してもよいし（例えば図１０を参照）、第１カバー部４０の下端縁及び第２カバー部４１の上端縁に沿って設けてもよい。要するに、ヒンジ結合部５は、右側面パネル１１に取り付けた第１カバー部４０に対して右側面パネル１１から取り外した第２カバー部４１を回動させることができる構成であれば、大きさ、形状及び配置に関わらず、種々の態様で実施することができる。 As shown in FIGS. 2 and 3, the hinge coupling portion 5 is integrally molded with the first cover portion 40 and the second cover portion 41, and is made of a flexible synthetic resin. The hinge joint portion 5 is for connecting the lower end portion of the first cover portion 40 and the upper end portion of the second cover portion 41, and is attached to the right side surface panel 11 as shown in FIGS. 6 to 8. The second cover portion 41 removed from the right side panel 11 is rotatably connected to the first cover portion 40. The hinge coupling part 5 is provided only in a substantially central portion in the width direction of the first cover part 40 and the second cover part 41. This is for facilitating the rotation of the second cover portion 41 with respect to the first cover portion 40. However, the hinge coupling portions 5 may be arranged side by side with an interval (see, for example, FIG. 10), or provided along the lower edge of the first cover portion 40 and the upper edge of the second cover portion 41. May be. In short, the hinge coupling part 5 has a size as long as the second cover part 41 detached from the right side panel 11 can be rotated with respect to the first cover part 40 attached to the right side panel 11. It can be implemented in various ways regardless of shape and arrangement.

空気調和機の室外機１００は、設置した後に、保護カバー４を取り外して接続バルブ３を露出させ、冷媒を追加補充したり、メンテナンスで接続バルブ３の周りを確認したりする等、接続バルブ３に関する作業を行う場合がある。その際、従来の室外機では、保護カバー４を固定している複数のネジを全て取り外さなければならないため、作業者にとって大きな負担となっていた。また、従来の室外機では、端子台及び接続バルブが共通の保護カバーで保護されているので、接続バルブのみをメンテナンスする場合であっても、接続バルブと共にメンテナンスが不要な端子台までも露出させることになっていた。そのため、従来の室外機では、露出した端子台の開口部から進入した埃又は水が原因で、電気品が故障する虞があり、品質の低下による信頼性の問題があった。 After the installation, the outdoor unit 100 of the air conditioner removes the protective cover 4 to expose the connection valve 3, and additionally replenishes the refrigerant, checks the surroundings of the connection valve 3 for maintenance, and the like. May be working on. At that time, in the conventional outdoor unit, it is necessary to remove all of the plurality of screws fixing the protective cover 4, which is a heavy burden on the operator. Further, in the conventional outdoor unit, since the terminal block and the connection valve are protected by the common protective cover, even when only the connection valve is maintained, the connection valve and the terminal block not requiring maintenance are exposed. It was supposed to. Therefore, in the conventional outdoor unit, there is a possibility that electrical products may break down due to dust or water that has entered through the exposed opening of the terminal block, and there is a problem of reliability due to deterioration of quality.

実施の形態１に係る空気調和機の室外機１００によれば、保護カバー４が、端子台２を覆う第１カバー部４０と、接続バルブ３を覆う第２カバー部４１と、筐体１の外面に取り付けられている第１カバー部４０に対して筐体１の外面から取り外された第２カバー部４１を回動自在に連結するヒンジ結合部５と、を有しているので、図６に示すように、端子台２を第１カバー部４０で保護した状態で、右側面パネル１１から取り外した第２カバー部４１を回動させて接続バルブ３のみを露出されることができる。よって、この室外機１００は、設置した後に、接続バルブ３を露出させて、冷媒を追加補充したり、メンテナンスで接続バルブ３の周りを確認したりする場合に、第１カバー部４０を取り外す作業が不要なので、作業者の負担を軽減させることができ、作業性に優れている。また、この室外機１００は、接続バルブ３を露出させた状態であっても、端子台２が第１カバー部４０で保護されているので、筐体１の内部に埃又は水が進入して電気品が故障する懸念もなく、品質を維持することができ、信頼性の高い室外機を実現できる。 According to the outdoor unit 100 for an air conditioner according to Embodiment 1, the protective cover 4 includes the first cover portion 40 that covers the terminal block 2, the second cover portion 41 that covers the connection valve 3, and the housing 1. Since the second cover portion 41 removed from the outer surface of the housing 1 is rotatably connected to the first cover portion 40 attached to the outer surface, the hinge coupling portion 5 is included in FIG. As shown in FIG. 7, the second cover portion 41 removed from the right side panel 11 can be rotated to expose only the connection valve 3 in a state where the terminal block 2 is protected by the first cover portion 40. Therefore, when the outdoor unit 100 is installed, the connection valve 3 is exposed to additionally replenish the refrigerant, and when the surroundings of the connection valve 3 are checked for maintenance, the work of removing the first cover portion 40 is performed. Since it is unnecessary, the burden on the worker can be reduced and workability is excellent. Further, in the outdoor unit 100, even when the connection valve 3 is exposed, the terminal block 2 is protected by the first cover section 40, so that dust or water may enter the inside of the housing 1. It is possible to realize a highly reliable outdoor unit that can maintain the quality without concern that the electrical components will break down.

なお、保護カバー４は、例えば第１カバー部４０と第２カバー部４１とをそれぞれ独立した構成とし、個別に筐体１の右側面パネル１１に着脱自在に取り付けられた構成もある。しかし、独立した第１カバー部と第２カバー部は、ネジ等の固定部材で、それぞれ右側面パネルに取り付ける必要がある。この場合、各カバー部は、３箇所或いは４箇所で右側面パネルにしっかりと固定する必要がある。そのため、ネジ孔を保護カバー及び右側面パネルのそれぞれに形成する必要があり、製造上コストが掛かる。また、第１カバー部及び第２カバー部をそれぞれ個別に取り付ける必要があるので、着脱作業が面倒であり作業者にとって負担が大きい。そこで、実施の形態１の空気調和機の室外機１００では、第１カバー部４０と第２カバー部４１とを一体成形することで、第１カバー部４０と第２カバー部４１とで右側面パネル１１に対する固定箇所を共有することができ、製造コストの削減、及び取付作業の作業性を向上させることとしている。 Note that the protective cover 4 may have a configuration in which, for example, the first cover portion 40 and the second cover portion 41 are independent of each other, and are individually detachably attached to the right side panel 11 of the housing 1. However, the independent first cover portion and the independent second cover portion need to be attached to the right side panel by fixing members such as screws. In this case, each cover part needs to be firmly fixed to the right side panel at three or four positions. Therefore, it is necessary to form the screw hole in each of the protective cover and the right side panel, which increases the manufacturing cost. Further, since it is necessary to individually attach the first cover portion and the second cover portion, the attachment/detachment work is troublesome and the burden on the operator is large. Therefore, in the outdoor unit 100 for an air conditioner according to the first embodiment, the first cover portion 40 and the second cover portion 41 are integrally molded so that the first cover portion 40 and the second cover portion 41 form the right side surface. It is possible to share the fixed portion with respect to the panel 11, reduce the manufacturing cost, and improve the workability of the mounting work.
