One mounting piece 55d of the electrical box main body 55a is fixed to the cover 59 via a screw 56a, and the other inclined mounting piece 55c is connected to the inclined portion of the inner plate 3b described above via a fixing screw 56b. It is fixed to 3c.

一方の取付片55d、及び他方の傾斜した取付片55cには、各々だるま穴55fがあけられ、電装箱本体55aを固定する場合、カバー59及び傾斜部3cの各々にねじ込まれた固定ビス56a,56bに、だるま穴55fが嵌め込まれ、電装箱蓋55bを横方向(矢印E方向)にスライドさせて、各固定ビス56a,56bを締め付けて、電装箱本体55aが固定されている。   The one mounting piece 55d and the other inclined mounting piece 55c are each provided with a saddle hole 55f, and when fixing the electrical box main body 55a, fixing screws 56a screwed into the cover 59 and the inclined portion 3c, A dart hole 55f is fitted into 56b, the electrical box lid 55b is slid in the lateral direction (arrow E direction), and the fixing screws 56a and 56b are tightened to fix the electrical box body 55a.

なお、内側板3bの傾斜部3cを、傾斜して折り曲げるに際しては、内側板3bの上端3hから、その下端3iまで達しない切り込み3gが設けられ、この切り込み3gの先端を横切る線に沿って、傾斜部3cを折り曲げている。
ここで、切り込み3gの位置は、傾斜部3cの範囲が電装箱55の取付部として機能するのに十分な大きさとなる位置であればよい。
When the inclined part 3c of the inner plate 3b is inclined and bent, a notch 3g that does not reach the lower end 3i from the upper end 3h of the inner plate 3b is provided, and along a line that crosses the tip of the notch 3g, The inclined portion 3c is bent.
Here, the position of the notch 3g may be a position where the range of the inclined portion 3c is large enough to function as the mounting portion of the electrical box 55.

傾斜部3cは、図5に示すように、内側板3bの下辺(下端部3aの面に一致する。)から上方に距離h0だけ離れた位置を基準に、電装箱55側(前面外装パネル2側)に所定の角度r1で屈曲されている。この角度r1は、内側板3bと傾斜部3cとの成す角度であり、本実施形態では、角度r1=約45度である。上記距離h0が設けられていることにより、この距離h0が設けられていない場合(h0=0)に比べ、背面外装パネル3の下部の剛性が高められている。   As shown in FIG. 5, the inclined portion 3 c is on the electrical box 55 side (front exterior panel 2) on the basis of a position away from the lower side of the inner plate 3 b (matches the surface of the lower end portion 3 a) by a distance h 0. Side) at a predetermined angle r1. The angle r1 is an angle formed by the inner plate 3b and the inclined portion 3c, and in the present embodiment, the angle r1 is about 45 degrees. By providing the distance h0, the rigidity of the lower portion of the rear exterior panel 3 is enhanced as compared with the case where the distance h0 is not provided (h0 = 0).

また、内側板3bの傾斜部3c以外の部分3dは、図4に示すように、ユニット本体1Aの長手方向一杯に延在し、この傾斜部3c以外の部分3dと、背面外装パネル3との間には、電装箱55から延びた配線31を収納する配線収納部33が形成されている。この配線収納部33は、配線31を収納するのに十分な大きさで形成され、下端部3aの寸法aと略同じ幅で形成されている。   Further, as shown in FIG. 4, the portion 3 d other than the inclined portion 3 c of the inner plate 3 b extends in the longitudinal direction of the unit main body 1 </ b> A, and the portion 3 d other than the inclined portion 3 c and the rear exterior panel 3 A wiring storage portion 33 that stores the wiring 31 extending from the electrical box 55 is formed therebetween. The wiring storage portion 33 is formed with a size sufficient to store the wiring 31, and is formed with a width substantially the same as the dimension a of the lower end portion 3a.

この配線31は、電装箱本体55aに配置された鳩目ゴム53を介して送風室24内に引き出され、電装箱本体55aに配置された電装箱側クランプ52で保持され、配線収納部33に収納され、この配線収納部33に沿って、図3に示すように、三つの外装パネル側クランプ51で保持された後、現地配線取入口38に導かれる。この現地配線取入口38は、背面外装パネル3の右面外装パネル5側に形成されており、ここには熱交換器22(図2)から延びるガス管36及びオイル管37も通され、これら管36,37は、図示せぬ室外機に接続されている。   The wiring 31 is drawn into the blower chamber 24 through the eyelet rubber 53 disposed in the electrical box main body 55a, held by the electrical box side clamp 52 disposed in the electrical box main body 55a, and stored in the wiring storage unit 33. Then, as shown in FIG. 3, along the wiring storage portion 33, after being held by the three exterior panel side clamps 51, it is guided to the local wiring intake 38. The local wiring inlet 38 is formed on the right side exterior panel 5 side of the rear exterior panel 3, and a gas pipe 36 and an oil pipe 37 extending from the heat exchanger 22 (FIG. 2) are also passed therethrough. 36 and 37 are connected to an outdoor unit (not shown).

本実施形態では、電装箱55を、内側板3bの傾斜部3cに取り付けた場合、図5に示すように、電装箱固定ビス56の頭とエアフィルタ26の間に距離hが生じ、従来のように、固定ビス56の頭とエアフィルタ26が干渉しない。従って、内側板3bの下端部3aとエアフィルタ26の間に隙間が生じることがなく、よって、吸込グリル11から流入した空気の一部が、エアフィルタ26を流通せずに、この隙間から送風室24に流入するといったトラブルが未然に解消される。   In this embodiment, when the electrical box 55 is attached to the inclined portion 3c of the inner plate 3b, a distance h is generated between the head of the electrical box fixing screw 56 and the air filter 26 as shown in FIG. Thus, the head of the fixing screw 56 and the air filter 26 do not interfere with each other. Accordingly, there is no gap between the lower end portion 3a of the inner plate 3b and the air filter 26, so that a part of the air flowing in from the suction grill 11 is blown from the gap without flowing through the air filter 26. Troubles such as flowing into the chamber 24 are eliminated.

また、内側板3bの外側に配線収納部33を設けたため、配線31をこの配線収納部33に収納することができ、これにより、吸込グリル11やエアフィルタ26を開放し、送風室24を露出したときに、配線収納部33に収納された配線31が外部から見え難いため、スッキリとした配線収納が可能になる。   Further, since the wiring storage portion 33 is provided outside the inner plate 3b, the wiring 31 can be stored in the wiring storage portion 33, thereby opening the suction grill 11 and the air filter 26 and exposing the air blowing chamber 24. When this is done, since the wiring 31 stored in the wiring storage unit 33 is difficult to see from the outside, the wiring can be stored clearly.

本構成では、天吊り状態で作業者が上を向いて、吸込グリル11やエアフィルタ26を外した場合、配線31が垂れ下がらず、メンテナンスの邪魔にならず、しかも、メンテナンス後に、作業者が上を向いて、吸込グリル11やエアフィルタ26を収める場合、配線31が邪魔にならず、簡単に収めることができる。
さらに、内側板3bに、外装パネル側クランプ51がねじ止めされるため、従来のように、外装パネル側クランプ51を背面外装パネル3に対し、例えばスポット溶接する必要がなく、作業性を向上させることができる。
In this configuration, when the operator faces upward in a suspended state and the suction grille 11 and the air filter 26 are removed, the wiring 31 does not hang down and does not interfere with the maintenance. When the suction grill 11 and the air filter 26 are stored facing upward, the wiring 31 does not get in the way and can be stored easily.
Furthermore, since the exterior panel side clamp 51 is screwed to the inner side plate 3b, the exterior panel side clamp 51 does not need to be spot-welded to the rear exterior panel 3 as in the prior art, thereby improving workability. be able to.

以上、一実施形態に基づいて本発明を説明したが、本発明は、これに限定されるものではない。例えば、傾斜部3cの傾斜角は45°に限定されず、要するに、固定ビス56とエアフィルタ26が干渉しない角度であればよい。また、上記実施形態では、内側板3bの端部に傾斜部3cを形成したが、この傾斜部3cは、電装箱の位置に応じて、その位置を変化させることができる。また、切り込み3gを設けることで、内側板3bと傾斜部3cを分けているが、内側板3bに切り込み3gを設けないで、プレス加工により傾斜部3cを一体形成してもよい。   As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this. For example, the inclination angle of the inclined portion 3 c is not limited to 45 °, and may be any angle as long as the fixed screw 56 and the air filter 26 do not interfere with each other. Moreover, in the said embodiment, although the inclination part 3c was formed in the edge part of the inner side board 3b, this inclination part 3c can change the position according to the position of an electrical equipment box. Although the inner plate 3b and the inclined portion 3c are separated by providing the cut 3g, the inclined portion 3c may be integrally formed by pressing without providing the cut 3g in the inner plate 3b.
