この状態で、第１ケース２３及び第２ケース２４を、ボルトＢ等で固定させる。このとき、必要に応じて、第２ケース２４のアース部機構３１に、基板２１のアース回路を接続する。   In this state, the first case 23 and the second case 24 are fixed with bolts B or the like. At this time, the ground circuit of the substrate 21 is connected to the ground part mechanism 31 of the second case 24 as necessary.

次に、第２ケース２４の係止部３２に、サブベース２５の爪部３５及び嵌合部３６を係合させてサブベース２５を固定させる。なお、サブベース２５のコネクタ端子４２ａに、外部電源に接続された電源ケーブルＫを接続させるとともに、電源ケーブルＫを固定部材４３により、サブベース２５に固定させる。また、電源ケーブルＫに接続されたコネクタ端子４２ａを有する電源部機構４２を基板２１の電源供給回路と接続させる。なお、この基板２１の電源供給回路は、例えば、基板２１、基板ベース２２及び第２ケース２４を接続させた際に、電源部機構４２と容易に接続可能なコネクタ等を用いても良い。   Next, the claw portion 35 and the fitting portion 36 of the sub base 25 are engaged with the locking portion 32 of the second case 24 to fix the sub base 25. A power cable K connected to an external power source is connected to the connector terminal 42 a of the sub base 25, and the power cable K is fixed to the sub base 25 by the fixing member 43. Further, the power supply mechanism 42 having the connector terminal 42 a connected to the power cable K is connected to the power supply circuit of the substrate 21. The power supply circuit of the substrate 21 may use a connector that can be easily connected to the power supply mechanism 42 when the substrate 21, the substrate base 22, and the second case 24 are connected, for example.

次に、第１ケース２３の上部の開口にリード線カバー２９を固定させるとともに、サブベース２５にコネクタカバー２８を固定させる。なお、基板２１と各構成品との電気的接続の詳細は省略する。   Next, the lead wire cover 29 is fixed to the opening at the top of the first case 23, and the connector cover 28 is fixed to the sub-base 25. Details of the electrical connection between the substrate 21 and each component are omitted.

次に、図２、３に示すように、第１ケース２３の第１取付部２３ａに、第１固定手段２６の切欠部２６ａを挿入し、第１ケース２３に第１固定手段２６を取り付ける。また、第１ケース２３の第２取付部２３ｂに、第２固定手段２７の軸部及び先端部を挿入するとともに、第２固定手段２７を後方にスライドさせることで、第１ケース２３に第２固定手段２７を取り付ける。   Next, as shown in FIGS. 2 and 3, the notch portion 26 a of the first fixing means 26 is inserted into the first mounting portion 23 a of the first case 23, and the first fixing means 26 is attached to the first case 23. Moreover, while inserting the axial part and front-end | tip part of the 2nd fixing means 27 in the 2nd attachment part 23b of the 1st case 23, the 2nd fixing means 27 is made to slide to the 1st case 23 by back. A fixing means 27 is attached.

このようにして、電気部品箱８が組み立てられる。次に、この組み立てた電気部品箱８を室内機本体５へ固定させる。   In this way, the electrical component box 8 is assembled. Next, the assembled electrical component box 8 is fixed to the indoor unit body 5.

図４に示すように、先ず、電気部品箱８を後板１２の取付部１５と対向させる。このとき、電気部品箱８の背面を、当接部１７と対向させる。併せて、第１固定手段２６を係止部１８と対向させるとともに、第２固定手段２７を被締結部１９と対向させて、電気部品箱８を配置する。   As shown in FIG. 4, first, the electrical component box 8 is opposed to the mounting portion 15 of the rear plate 12. At this time, the back surface of the electrical component box 8 is opposed to the contact portion 17. In addition, the electric component box 8 is arranged with the first fixing means 26 facing the locking portion 18 and the second fixing means 27 facing the fastened portion 19.

この状態で、電気部品箱８の背面を当接部１７に近接させるとともに、第１固定手段２６を係止部１８に係止させる。具体的には、係止部１８の下方から第１固定手段２６を滑り入れ、電気部品箱８の背面を当接部１７と当接させる。併せて、第２固定手段２７を被締結部１９と対向させ、第２固定手段２７の挿通孔２７ａと被締結部１９とを位置合わせし、ボルトＢを被締結部１９に締結させる。これにより、電気部品箱８は、後板１２の取付部１５に固定されることとなる。   In this state, the back surface of the electrical component box 8 is brought close to the contact portion 17 and the first fixing means 26 is locked to the locking portion 18. Specifically, the first fixing means 26 is slid from below the locking portion 18, and the back surface of the electrical component box 8 is brought into contact with the contact portion 17. At the same time, the second fixing means 27 is opposed to the fastened portion 19, the insertion hole 27 a of the second fixing means 27 and the fastened portion 19 are aligned, and the bolt B is fastened to the fastened portion 19. Thereby, the electrical component box 8 is fixed to the mounting portion 15 of the rear plate 12.

なお、このとき、第１固定手段２６及び第２固定手段２７は、第１ケース２３に設けられている。即ち、第１ケース２３が、第１固定手段２６及び第２固定手段２７を介して後板１２に固定される。このため、基板２１、基板ベース２２、第２ケース２４、サブベース２５、コネクタカバー２８及びリード線カバー２９は、第１ケース２３を介して後板１２に固定されることとなる。   At this time, the first fixing means 26 and the second fixing means 27 are provided in the first case 23. That is, the first case 23 is fixed to the rear plate 12 via the first fixing means 26 and the second fixing means 27. For this reason, the substrate 21, the substrate base 22, the second case 24, the sub base 25, the connector cover 28, and the lead wire cover 29 are fixed to the rear plate 12 via the first case 23.

このため、例えば、基板２１の交換等の基板２１のメンテナンス時には、図５に示すように、第１ケース２３を後板１２に固定した状態で、基板２１を脱離させる。
具体的に説明すると、図５に示すように、先ず、第１ケース２３と第２ケース２４とを固定しているボルトＢを取り外す。また、第１ケース２３から、リード線カバー２９を脱離させる。この状態で、第２ケース２４を第１ケース２３から引き出して、第１ケース２３と第２ケース２４とを離間させることで、第２ケース２４に固定された基板２１、基板ベース２２、サブベース２５、及びコネクタカバー２８を第１ケースから脱離させることが可能となる。 For this reason, for example, during maintenance of the substrate 21 such as replacement of the substrate 21, the substrate 21 is detached while the first case 23 is fixed to the rear plate 12, as shown in FIG.
More specifically, as shown in FIG. 5, first, the bolt B that fixes the first case 23 and the second case 24 is removed. Further, the lead wire cover 29 is detached from the first case 23. In this state, the second case 24 is pulled out from the first case 23 and the first case 23 and the second case 24 are separated from each other, whereby the substrate 21, the substrate base 22, and the sub-base fixed to the second case 24. 25 and the connector cover 28 can be detached from the first case.

さらに、基板２１を交換する場合には、コネクタカバー２８を脱離させるとともに、第２ケース２４からサブベース２５を脱離させ、その後、第２ケース２４から基板ベース２２を脱離させてから、基板２１を基板ベース２２から脱離させればよい。   Further, when replacing the substrate 21, the connector cover 28 is detached, the sub base 25 is detached from the second case 24, and then the substrate base 22 is detached from the second case 24. The substrate 21 may be detached from the substrate base 22.

脱離させた基板２１を交換後、再度、基板２１を基板ベース２２に組立てるとともに、基板ベース２２を第２ケース２４に組み立てる。併せて、第２ケース２４にサブベース２５及びコネクタカバー２８を組み合わせる。この基板２１及びその他構成品を組み合わせた第２ケース２４を第１ケース２３に挿入し、第２ケース２４を第１ケース２３にボルトＢにより固定させるとともに、リード線カバー２９を第１ケース２３に組み立てる。このように基板２１の交換作業がなされることとなる。   After replacing the detached substrate 21, the substrate 21 is assembled again to the substrate base 22, and the substrate base 22 is assembled to the second case 24. At the same time, the sub base 25 and the connector cover 28 are combined with the second case 24. The second case 24 in which the substrate 21 and other components are combined is inserted into the first case 23, and the second case 24 is fixed to the first case 23 with bolts B, and the lead wire cover 29 is attached to the first case 23. assemble. In this way, the replacement work of the substrate 21 is performed.

このように構成された電気部品箱８を用いた空気調和機の室内機１は、室内機本体５の後板１２の取付部１５に電気部品箱８を確実に固定することが可能となる。なお、室内機本体５の形状や仕様が異なる場合には、取付部１５の係止部１８及び被締結部１９の位置や形状等の細部の構造が異なる。   The indoor unit 1 of the air conditioner using the electrical component box 8 configured in this way can securely fix the electrical component box 8 to the mounting portion 15 of the rear plate 12 of the indoor unit body 5. In addition, when the shape and specification of the indoor unit main body 5 are different, detailed structures such as the positions and shapes of the locking portion 18 and the fastened portion 19 of the mounting portion 15 are different.

しかし、電気部品箱８は、第１ケース２３に第１固定手段２６及び第２固定手段２７が着脱自在に固定される構成であるため、取付部１５に適した形状の第１固定手段２６及び第２固定手段２７を第１ケース２３に取り付けることで、各形状の室内機本体５に電気部品箱８を取り付けることが可能となる。なお、電気部品箱８の位置合わせ、及び、取付部１５と各固定手段２６，２７との位置合わせのため、各室内機本体５の取付部１５の当接部１７は、第１ケース２３の背面と当接可能に形成されている。   However, since the electrical component box 8 has a configuration in which the first fixing means 26 and the second fixing means 27 are detachably fixed to the first case 23, the first fixing means 26 having a shape suitable for the mounting portion 15 and By attaching the 2nd fixing means 27 to the 1st case 23, it becomes possible to attach the electrical component box 8 to the indoor unit main body 5 of each shape. In addition, the contact part 17 of the attachment part 15 of each indoor unit main body 5 is the position of the first case 23 for the alignment of the electrical component box 8 and the alignment of the attachment part 15 and each fixing means 26, 27. It is formed so as to be able to contact the back surface.

このように、仕様が異なる室内機本体５であっても、第１、第２固定手段２６、２７を適切な形状のものと交換することで、室内機本体５の構造が異なっても、各構成品、例えば、第１ケース２３、第２ケース２４、サブベース２５、コネクタカバー２８、及び、リード線カバー２９を共用することが可能となる。   As described above, even if the indoor unit body 5 has different specifications, the first and second fixing means 26 and 27 can be replaced with ones having an appropriate shape, so that the structure of the indoor unit body 5 is different. Components such as the first case 23, the second case 24, the sub base 25, the connector cover 28, and the lead wire cover 29 can be shared.

また、サブベース２５の外郭部材４１の外形状及びコネクタカバー２８の外形状を、出荷が想定される各国仕様の電源部機構４２を配置及び収納可能な外形状に形成することで、各国に出荷する場合であっても、サブベース２５及びコネクタカバー２８を共用することが可能となる。   Further, the outer shape of the outer member 41 of the sub-base 25 and the outer shape of the connector cover 28 are shipped to each country by forming the power supply unit mechanism 42 of the country-specific specifications expected to be shipped and accommodated. Even in this case, the sub-base 25 and the connector cover 28 can be shared.

また、第１ケース２３と第２ケース２４との結合を解除することで、第２ケース２４に固定された基板ベース２２を第１ケース２３から脱離させることが可能となり、第１ケース２３を後板１２へ固定させた状態で、基板２１の着脱が自在となる。このため、基板２１の着脱が容易となり、電気部品箱８のメンテナンスが容易となる。   Further, by releasing the coupling between the first case 23 and the second case 24, the substrate base 22 fixed to the second case 24 can be detached from the first case 23, and the first case 23 is removed. The substrate 21 can be freely attached and detached while being fixed to the rear plate 12. For this reason, the substrate 21 can be easily attached and detached, and the maintenance of the electrical component box 8 is facilitated.
