　次に空気調和機１００の動作を説明する。電源配線６から供給される交流電力は制御基板２６ｄに実装されたコンバータ回路で直流電力に変換され、変換された直流電力はインバータ回路によって所望の周波数の交流電力に変換され、室内機２の送風機へ供給される。送風機のファンモータが回転することにより、化粧パネル２２の吸込口２２ｂから室内空気が吸い込まれ、吸込口２２ｂを通過した室内空気は室内機２内の熱交換器を通過する際に熱交換され、熱交換された空気は吹出口２４ａより室内に吹出される。このとき熱交換器で結露した水はドレン水としてドレンパン２４に集められる。ドレンパン２４を清掃する場合、電気品箱２６の蓋２６ｂが取外され、電気品箱２６内に導入される複数の配線の各々に接続された雌コネクタを、中継配線に接続される雄コネクタから引き抜き、その後に電気品箱２６を固定する締結部材４１を緩めて取外すことにより、電気品箱２６がドレンパン２４から取外される。最後に室内機２の筐体２１にドレンパン２４を固定している締結部材４０を緩めて取外すことにより、ドレンパン２４が室内機２の筐体２１から取外される。 Next, the operation of the air conditioner 100 will be described. The AC power supplied from the power supply wiring 6 is converted into DC power by a converter circuit mounted on the control board 26d, and the converted DC power is converted into AC power having a desired frequency by an inverter circuit. Supplied to. When the fan motor of the blower rotates, room air is sucked from the suction port 22b of the decorative panel 22, and the room air that has passed through the suction port 22b is heat-exchanged when passing through the heat exchanger in the indoor unit 2, The heat-exchanged air is blown out into the room through the air outlet 24a. At this time, the water condensed in the heat exchanger is collected in the drain pan 24 as drain water. When cleaning the drain pan 24, the lid 26b of the electrical component box 26 is removed, and the female connector connected to each of the plurality of wires introduced into the electrical component box 26 is removed from the male connector connected to the relay wiring. The electrical component box 26 is removed from the drain pan 24 by pulling and then loosening and removing the fastening member 41 that fixes the electrical component box 26. Finally, the drain pan 24 is removed from the casing 21 of the indoor unit 2 by loosening and removing the fastening member 40 that fixes the drain pan 24 to the casing 21 of the indoor unit 2.
　従来の空気調和機では、電気品箱の外部から電気品箱内に導入される複数の配線が電気品箱内の端子台に接続されているため、電気品箱をドレンパンから取外す場合、電気品箱の蓋を取外してから、端子台にネジ止めされている複数の配線を取外す作業が必要になる。特に天井埋込形室内機では構造上の制約により、電気品箱内のスペースが狭いため、従来の空気調和機では、端子台から複数の配線を取外すための作業時間が長くなるという問題があった。一方、取外した電気品箱を室内機に設置する場合、ドレンパンを室内機の筐体に固定し、その後に電気品箱を筐体に固定する。そして電気品箱内に複数の配線を導入して、それらの配線を電気品箱内に設置された端子台にネジ止めする必要がある。従って従来の空気調和機では配線の接続作業時間が長くなるだけでなく、配線を誤接続する可能性があるという問題があった。実施の形態１に係る空気調和機１００では、電気品箱２６内に導入される複数の配線と電気品箱２６の端子台に接続された中継配線とがコネクタで着脱可能である。そのため、電気品箱２６をドレンパン２４から取外す場合、雄コネクタと雌コネクタの接続を解除するだけで複数の配線を制御基板２６ｄから取外すことができ、配線の取外しに伴う作業時間を短縮することができる。また実施の形態１に係る空気調和機１００では、雄コネクタを雌コネクタに接続するだけで電気品箱２６内に導入された複数の配線を電気品箱２６の端子台に接続することができるため、ドレンパン２４の清掃完了後の配線時間を短縮することができる。また空気調和機１００では、コネクタが誤接続防止構造を有するため、ワイヤードリモコン配線５および室内外配線３のように極性のある配線を接続する場合でも異極性同士が誤接続されることを防止できる。 In conventional air conditioners, multiple wires introduced from the outside of the electrical box to the electrical box are connected to the terminal block in the electrical box, so when removing the electrical box from the drain pan, After removing the lid of the box, it is necessary to remove a plurality of wires screwed to the terminal block. In particular, because the space in the electrical box is narrow due to structural restrictions in the ceiling-embedded indoor unit, the conventional air conditioner has a problem that it takes a long time to remove multiple wires from the terminal block. It was. On the other hand, when installing the removed electric component box in the indoor unit, the drain pan is fixed to the casing of the indoor unit, and then the electric component box is fixed to the casing. Then, it is necessary to introduce a plurality of wires into the electrical component box and to screw them to a terminal block installed in the electrical component box. Therefore, in the conventional air conditioner, there is a problem that not only the wiring connection work time is lengthened, but also the wiring may be erroneously connected. In the air conditioner 100 according to Embodiment 1, a plurality of wires introduced into the electrical component box 26 and relay wires connected to the terminal block of the electrical component box 26 are detachable with connectors. Therefore, when the electrical component box 26 is removed from the drain pan 24, a plurality of wires can be removed from the control board 26d simply by releasing the connection between the male connector and the female connector, and the work time associated with the removal of the wires can be shortened. it can. Further, in the air conditioner 100 according to Embodiment 1, a plurality of wires introduced into the electrical component box 26 can be connected to the terminal block of the electrical component box 26 simply by connecting the male connector to the female connector. The wiring time after completion of cleaning of the drain pan 24 can be shortened. Further, in the air conditioner 100, since the connector has a structure for preventing erroneous connection, it is possible to prevent erroneous connection between different polarities even when connecting polar wiring such as the wired remote control wiring 5 and the indoor / outdoor wiring 3. .

　実施の形態２の室内機２Ａにおいてドレンパン２４を清掃する場合、ドレンパン２４に設置された複数の雌コネクタと複数の雄コネクタとの接続を解除し、締結部材４１を外すことで電気品箱２６がドレンパン２４から取外され、締結部材４０を外すことでドレンパン２４が室内機２Ａの筐体２１から取外される。このように蓋２６ｂを取外す作業が不要になるため、ドレンパン２４の清掃を始める際の作業時間をより一層短縮することができる。 When the drain pan 24 is cleaned in the indoor unit 2A of the second embodiment, the connection between the plurality of female connectors and the plurality of male connectors installed in the drain pan 24 is released, and the fastening member 41 is removed, so that the electrical component box 26 is removed. The drain pan 24 is removed from the drain pan 24 and the fastening member 40 is removed to remove the drain pan 24 from the casing 21 of the indoor unit 2A. Thus, since the operation | work which removes the cover 26b becomes unnecessary, the operation | work time at the time of starting the cleaning of the drain pan 24 can be shortened further.
　実施の形態２の室内機２Ａにおいて、電気品箱２６を室内機２Ａに設置する場合、締結部材４０でドレンパン２４を室内機２Ａの筐体２１に固定し、締結部材４１で電気品箱２６を筐体２１に固定する。このとき電気品箱２６は図７に示す蓋２６ｂが取付けられた状態で筐体２１に固定される。電気品箱２６を筐体２１に固定した後、第１のコネクタ３０、第２のコネクタ５０および第３のコネクタ６０を接続することにより電源配線６、ワイヤードリモコン配線５、および室内外配線３の各々が電気品箱２６内の複数の端子台の各々と電気的に接続される。蓋２６ｂを取付ける作業が不要になるため、電気品箱２６を取付ける際の配線作業時間をより一層短縮することができる。 In the indoor unit 2A of the second embodiment, when the electrical component box 26 is installed in the indoor unit 2A, the drain pan 24 is fixed to the casing 21 of the indoor unit 2A with the fastening member 40, and the electrical component box 26 is secured with the fastening member 41. Fix to the housing 21. At this time, the electrical component box 26 is fixed to the casing 21 with the lid 26b shown in FIG. After fixing the electrical box 26 to the housing 21, the first connector 30, the second connector 50, and the third connector 60 are connected to connect the power supply wiring 6, the wired remote control wiring 5, and the indoor / outdoor wiring 3. Each is electrically connected to each of a plurality of terminal blocks in the electrical component box 26. Since the work of attaching the lid 26b is not required, the wiring work time when attaching the electrical component box 26 can be further reduced.
実施の形態３．
　図９は本発明の実施の形態３に係る空気調和機に用いられるコネクタの斜視図である。以下、実施の形態１と同一部分には同一符号を付してその説明を省略し、ここでは異なる部分についてのみ述べる。実施の形態３では実施の形態１，２の第２のコネクタ５０の変形例である第２のコネクタ５０Ａの構造を説明するが、第１のコネクタ３０および第３のコネクタ６０も第２のコネクタ５０Ａと同様に構成してもよい。 Embodiment 3 FIG.
FIG. 9 is a perspective view of a connector used in the air conditioner according to Embodiment 3 of the present invention. Hereinafter, the same parts as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Only different parts will be described here. In the third embodiment, the structure of the second connector 50A, which is a modification of the second connector 50 of the first and second embodiments, will be described. The first connector 30 and the third connector 60 are also the second connector. You may comprise similarly to 50A.
　図９に示す第２のコネクタ５０Ａは第２の雄コネクタ５１Ａと第２の雌コネクタ５２Ａを有する。第２の雄コネクタ５１Ａは、雄側ハウジング５１ａと、雄側ハウジング５１ａの側面に設置されて、第２の雄コネクタ５１Ａと第２の雌コネクタ５２Ａとが離間する方向への移動を規制する規制部材であるクリップ５１ｂとを有する。クリップ５１ｂは、雄側ハウジング５１ａの一端５１ａ１１から雄側ハウジング５１ａの他端５１ａ１２に向けて伸びる板状に形成される。クリップ５１ｂは、一端５１ａ１１に形成される押圧部５１ｂ１と、クリップ５１ｂから雌側ハウジング５２ａに向かって突出し、第２の雌コネクタ５２Ａに形成された窪み部５２ｃに係合する係合部５１ｂ２とを有する。 The second connector 50A shown in FIG. 9 has a second male connector 51A and a second female connector 52A. The second male connector 51A is installed on the male housing 51a and the side surface of the male housing 51a, and restricts movement in a direction in which the second male connector 51A and the second female connector 52A are separated from each other. And a clip 51b which is a member. The clip 51b is formed in a plate shape extending from one end 51a11 of the male housing 51a toward the other end 51a12 of the male housing 51a. The clip 51b includes a pressing portion 51b1 formed at one end 51a11 and an engaging portion 51b2 that protrudes from the clip 51b toward the female housing 52a and engages with a recess 52c formed in the second female connector 52A. Have.
　雄側ハウジング５１ａは、複数の突起５１ａ３と起立部５１ａ４とを有する。起立部５１ａ４は、雄側ハウジング５１ａの長手面側の側面に、雄側ハウジング５１ａの軸線と直行する方向に突出する。起立部５１ａ４の端部にはクリップ５１ｂが設置される。クリップ５１ｂは、起立部５１ａ４を介して雄側ハウジング５１ａと連結する。押圧部５１ｂ１と係合部５１ｂ２は、起立部５１ａ４を支点として、Ｘａ方向またはＸｂ方向に変位する。具体的には、押圧部５１ｂ１が雄側ハウジング５１ａの方向に押されたとき、押圧部５１ｂ１が雄側ハウジング５１ａに接近し、係合部５１ｂ２が雄側ハウジング５１ａから離れるように、クリップ５１ｂは回動する。押圧部５１ｂ１への押圧力がなくなると、起立部５１ａ４の弾性復元力により、押圧部５１ｂ１が雄側ハウジング５１ａから離れ、係合部５１ｂ２が雄側ハウジング５１ａに接近するように、クリップ５１ｂは回動する。 The male housing 51a has a plurality of protrusions 51a3 and standing parts 51a4. The upright part 51a4 protrudes in a direction orthogonal to the axis of the male housing 51a on the side surface on the long side of the male housing 51a. A clip 51b is installed at the end of the standing portion 51a4. The clip 51b is connected to the male housing 51a via the upright portion 51a4. The pressing part 51b1 and the engaging part 51b2 are displaced in the Xa direction or the Xb direction with the rising part 51a4 as a fulcrum. Specifically, when the pressing portion 51b1 is pressed in the direction of the male housing 51a, the clip 51b is moved so that the pressing portion 51b1 approaches the male housing 51a and the engaging portion 51b2 is separated from the male housing 51a. Rotate. When the pressing force to the pressing part 51b1 is lost, the clip 51b is rotated so that the pressing part 51b1 is separated from the male housing 51a and the engaging part 51b2 approaches the male housing 51a by the elastic restoring force of the standing part 51a4. Move.
　第２の雌コネクタ５２Ａは、雌側ハウジング５２ａと、雌側ハウジング５２ａの側面に形成され、クリップ５１ｂが係合する窪み部５２ｃと、複数の窪み部５２ａ３を有する。 The second female connector 52A has a female housing 52a, a hollow portion 52c formed on the side surface of the female housing 52a, with which the clip 51b is engaged, and a plurality of hollow portions 52a3.
　第２の雄コネクタ５１Ａと第２の雌コネクタ５２Ａとを接続する場合、雄側ハウジング５１ａの突起５１ａ３と雌側ハウジング５２ａの窪み部５２ａ３とを対向させた状態で、雄側ハウジング５１ａがＺｂ方向に向かって雌側ハウジング５２ａの中空部５２ｂに挿入される。このとき、クリップ５１ｂの係合部５１ｂ２が雌側ハウジング５２ａの側面に接して、クリップ５１ｂの先端部５１ｂ３がＸａ方向に変移する。このときクリップ５１ｂの係合部５１ｂ２は、起立部５１ａ４の弾性復元力により、雌側ハウジング５２ａ側に付勢されている。そのため、雄側ハウジング５１ａが更にＺｂ方向に押し込まれて、係合部５１ｂ２が窪み部５２ｃの位置に到達したとき、係合部５１ｂ２は起立部５１ａ４の弾性復元力により窪み部５２ｃに係合する。これにより第２の雄コネクタ５１Ａと第２の雌コネクタ５２Ａとの接続が完了する。 When connecting the second male connector 51A and the second female connector 52A, the male housing 51a is in the Zb direction with the projection 51a3 of the male housing 51a and the recess 52a3 of the female housing 52a facing each other. Toward the hollow portion 52b of the female housing 52a. At this time, the engaging part 51b2 of the clip 51b is in contact with the side surface of the female housing 52a, and the tip part 51b3 of the clip 51b is shifted in the Xa direction. At this time, the engaging part 51b2 of the clip 51b is urged toward the female housing 52a by the elastic restoring force of the standing part 51a4. Therefore, when the male housing 51a is further pushed in the Zb direction and the engaging part 51b2 reaches the position of the recessed part 52c, the engaging part 51b2 engages with the recessed part 52c by the elastic restoring force of the standing part 51a4. . Thereby, the connection between the second male connector 51A and the second female connector 52A is completed.
　第２の雄コネクタ５１Ａを第２の雌コネクタ５２Ａから取外す場合、クリップ５１ｂの押圧部５１ｂ１をＸｂ方向に押し込むことにより、係合部５１ｂ２が窪み部５２ｃから外れる。押圧部５１ｂ１をＸｂ方向に押した状態で第２の雄コネクタ５１ＡをＺａ方向に引き抜くことにより、第２の雄コネクタ５１Ａが第２の雌コネクタ５２Ａから取外される。このように実施の形態３のコネクタによれば、接続完了後のコネクタ抜けを防止することができる。 When detaching the second male connector 51A from the second female connector 52A, the engaging portion 51b2 is detached from the recessed portion 52c by pushing the pressing portion 51b1 of the clip 51b in the Xb direction. The second male connector 51A is removed from the second female connector 52A by pulling out the second male connector 51A in the Za direction with the pressing portion 51b1 pushed in the Xb direction. Thus, according to the connector of Embodiment 3, it is possible to prevent the connector from being disconnected after the connection is completed.

You may form a hollow part in. The restricting member of the third embodiment is not limited to the illustrated example as long as the structure restricts the movement in the direction in which the male connector and the female connector are separated from each other. For example, a claw-shaped locking member is formed on both sides of the short side of the male housing, and a recess in which the locking member is locked on both of the short side of the female housing. A part may be formed. As another example of the restricting member, a protrusion may be formed on the side surface on the long side of the male housing, and a hollow portion on which the protrusion is locked may be formed on the side surface on the long side of the female housing. . Further, in the air conditioner 100 according to the first to third embodiments, the ceiling-embedded indoor units 2 and 2A are used. However, the air conditioner 100 according to the first to third embodiments is embedded in the ceiling. The present invention can also be applied to other indoor units such as a ceiling-suspended type, a ceiling cassette type, or a wall-hanging type indoor unit. Moreover, in the air conditioner 100 of Embodiment 1 to Embodiment 3, although the rectangular connector was used, the shape of a connector may be cylindrical. In the air conditioner 100 of the first to third embodiments, connectors are used for all three types of wiring connected to the electrical component box 26. However, any one of the three types of wiring is used. A connector may be used, and even in such a configuration, it is possible to shorten the wiring time. However, in the air conditioner 100 of the second embodiment, it is desirable to use connectors for all three types of wiring. In the air conditioner 100 according to the first to third embodiments, the drain introduction unit 24d1 into which the indoor / outdoor wiring 3 is introduced and the wiring introduction unit into which the wired remote control wiring 5 and the power supply wiring 6 are introduced into the drain pan 24. 24d2 is formed, but the wiring introduction part for introducing the indoor / outdoor wiring 3, the wired remote control wiring 5 and the power supply wiring 6 is not limited to the illustrated example. For example, one wiring introduction portion that introduces the indoor / outdoor wiring 3, the wired remote control wiring 5, and the power supply wiring 6 at a time may be formed in the drain pan 24.
