本発明は、空気調和機の室外機に関する。
The present invention relates to an outdoor unit of an air conditioner.
空気調和機の室外機の内部には、圧縮機や熱交換器が配置されるとともに、圧縮機や電動弁などを制御する制御基板が配置される。室外機は、室内機からの電源線が接続される端子台を有しており、その端子台は、室外機の側面近傍に配置された端子台取付け板に取り付けられる。従来の室外機では、制御基板が水平に配置されるのが一般的である。
In the outdoor unit of the air conditioner, a compressor and a heat exchanger are arranged, and a control board for controlling the compressor, a motorized valve, and the like is arranged. The outdoor unit has a terminal block to which a power line from the indoor unit is connected, and the terminal block is attached to a terminal block mounting plate disposed in the vicinity of the side surface of the outdoor unit. In a conventional outdoor unit, the control board is generally arranged horizontally.
室外機の熱交換器の側方において、制御基板を鉛直方向に沿って配置するとともに、端子台取付け板を制御基板に対して平行に配置することが考えられる。この室外機において熱交換効率を向上させるために熱交換器を大型化することが考えられるが、このとき、熱交換器の側方に配置される制御基板の配置空間が小さくなって、制御基板を端子台取付け板に対して斜めに配置されることがある。したがって、室外機内部の背面側において、制御基板と端子台取付け板との間の距離が狭くなって、室外機の前面側から制御基板に対するハーネスの接続作業を行うときの作業性が悪いという問題がある。

In order to improve the heat exchange efficiency in this outdoor unit, it is conceivable to increase the size of the heat exchanger, but at this time, the arrangement space of the control board arranged on the side of the heat exchanger becomes small, and the control board May be disposed obliquely with respect to the terminal block mounting plate. Therefore, on the back side inside the outdoor unit, the distance between the control board and the terminal block mounting plate becomes narrow, and the workability when the harness is connected to the control board from the front side of the outdoor unit is poor. There is.

Thus, the harness can be efficiently connected to the control board 17 during assembly.
本実施形態の室外機１では、端子台取付け板１９を制御基板１７から離れるように回動させるには、端子台取付け板１９の回動方向に配管などの部材が配置されない空間を設ける必要があるが、例えば、端子台取付け板１９の背面側端部近傍にある略鉛直方向に沿った回転軸の周りを端子台取付け板１９の前端部が制御基板１７から離れるように回動させる場合、端子台取付け板１９の回動方向に配管などの部材が配置されており、端子台取付け板１９を大きく回動させることができないことがある。本発明では、端子台取付け板１９の上端部近傍にある略水平方向に沿った回転軸の周りを端子台取付け板の下端部１９が制御基板１７から離れるように回動するので、端子台取付け板１９を大きく回動させることができる。
In the outdoor unit 1 of the present embodiment, in order to rotate the terminal block mounting plate 19 away from the control board 17, it is necessary to provide a space where a member such as a pipe is not disposed in the rotating direction of the terminal block mounting plate 19. However, for example, when rotating the front end of the terminal block mounting plate 19 away from the control board 17 around the rotation axis along the substantially vertical direction in the vicinity of the rear side end of the terminal block mounting plate 19, A member such as a pipe is arranged in the rotating direction of the terminal block mounting plate 19, and the terminal block mounting plate 19 may not be able to be rotated greatly. In the present invention, since the lower end portion 19 of the terminal block mounting plate is rotated around the rotation axis in the vicinity of the upper end portion of the terminal block mounting plate 19 in the substantially horizontal direction so as to be separated from the control board 17, the terminal block mounting is performed. The plate 19 can be greatly rotated.
本実施形態の室外機１では、制御基板１７の強電部１７ａが室外機１の前面側に配置され、制御基板１７の弱電部１７ｂが室外機１の背面側に配置されており、組み立て時において、室外機１の前面側から制御基板１７に対して行われるハーネスの接続作業の多くは、制御基板１７の弱電部１７ｂに対して行われる。したがって、室外機１内部の背面側において、制御基板１７と端子台取付け板１９との間の距離が狭くなった部分に配置された制御基板１７の弱電部１７ｂに対するハーネスの接続作業が行われるときに、本発明は特に有効である。
