As shown in FIG. 5, the electrical component box main body case 141. Cut and raised pieces 141e and 141f formed obliquely inside the left and right side pieces 141a and 141b of 141, guide the edges on both sides of the board mounting base 142, and the tips are the back pieces of the electrical component box body case 141. By inserting until it hits 141c, the back end is inclined so as to be farther from the top plate 111 than the front end, and in FIG. 3 and FIG. 4, the back surface is directed to the front surface (front side). Thereby, the control board 143 attached to the back surface also inclines and faces the front surface (front side). As shown in the enlarged view of FIG. 5, one of the cut and raised pieces 141f includes cut and raised portions 141f1 and 141f2 and a slit 141f3 formed between the cut and raised portions 141f1 and 141f2. The side edges of the table 142 are guided. The other cut-and-raised piece 141e is not shown in the enlarged view, but is the same.

  As shown in FIG. 5, reinforcing flanges 142a and 142b are formed on the board mounting base 142 by bending downward on the front end side and the rear end side in the insertion direction to the electrical component box body case 141. Yes. Notches 142a1 are formed at both ends of the front-end reinforcing flange 142a so that the reinforcing flange 142a does not get in the way when being guided by the cut and raised pieces 141e and 141f of the electrical component box body case 141. . The board mounting base 142 is fixed without screwing and is prevented from being pulled out by screwing the reinforcing flange 142a to the back piece 141c of the electrical equipment box body case 141 and attaching the electrical equipment box cover 143.

  The board mounting base 142 functions as a beam for maintaining the distance between the upper portions in FIGS. 3 to 6 of both side pieces 141a and 141b of the electrical component box body case 141 by being incorporated in the electrical component box body case 141. To do. Although there is no beam for maintaining the distance between the lower portions of the side pieces 141a and 141b in FIGS. 3, 4 and 6, the function of the beam of that portion is exhibited by mounting the board mounting base 142 obliquely. Can do.

  In this way, the board mounting base 142 can be easily attached to the electrical component box 140 together with the control board 144, the electrical component box cover 143 is removed, and the screw fastening to the back piece 141c of the reinforcing flange 142a is removed. Therefore, it can be easily removed by pulling it out along the cut and raised pieces 141e and 141f. In addition, since the board mounting base 142 covers the upper side of the electrical component box 140 in an inclined state, the control board 144 attached to the back surface thereof can be easily seen from the outside simply by removing the electrical component box cover 143.

  FIG. 7 shows a part of the electrical component box 140 from which the electrical component box cover 143 and the hanging bracket 150 are removed when the air conditioner 100 is vertically arranged. FIG. 8 shows a portion of the electrical component box 140 from which the electrical component box cover 143 is removed when the air conditioner 100 is horizontally arranged and looked up from below. Thus, in either case of horizontal arrangement or vertical arrangement, the control board 144 can be easily seen from the outside, and workability with respect to the control board 144 in maintenance or the like is improved. Moreover, since it mounts | wears with inclination, the control board 144 can be enlarged.

  Inside the electrical component box 140, inside the one side piece 141b of the electrical component box main body 141, a terminal block mounting base 145 is in a cantilevered form as shown in FIG. 3, FIG. 4, and FIG. Inclined so as to face downward, and is attached by screwing. This terminal block mounting base 145 is formed with a reinforcing flange 145a by bending both end portions, and the central portion is bent so that the ridge line 145b faces outward at a slight angle. A terminal block 146 is attached to the attachment surface 145c. That is, the terminal block mounting base 145 has the terminal block mounting surface 145c facing the surface continuous with the side plate 112 of the air conditioner main body case 110 and facing the surface continuous with the bottom plate 114 of the air conditioner main body case 110, and The electrical component box body case 141 is attached so as to face the side piece 141a. A power cord, a ground wire, etc. are connected to the terminal block 146 (not shown).

  Therefore, when the electrical component box cover 142 is removed, the terminal block 146 faces the surface continuous to the bottom plate 114 of the air conditioner main body case 141 and faces the surface continuous to the side plate 112, and the electrical component box main body case 141. Since it faces the side piece 141a, when the air conditioner 100 is arranged vertically, it is exposed to the outside obliquely upward as shown in FIG. 7, and is easy to see from the upper side of the bottom plate 114 and the upper side of the side plate 112 of the air conditioner 100. Become. Further, when it is disposed horizontally, it is exposed to the outside obliquely downward as shown in FIG. Therefore, workability for the terminal block 146 for maintenance or the like is improved. Further, since the terminal block mounting base 145 is cantilevered by the side piece 141b of the electrical component box body case 141, a relatively large space is formed between the terminal piece mounting base 145 and the back piece 141c. It is possible to mount an electrical component such as a relatively large transformer 147 (see FIGS. 6 and 8, etc.) on the inside.

  In addition, when the air conditioner 100 cannot be directly fixed to the floor when the air conditioner 100 is vertically arranged, the floor bracket attachment 160 is replaced with the side plates 112 and 113 or the electrical equipment as shown in FIG. It is attached to the product box 140 (however, only the side plate 112 side is shown in FIG. 9), the spacer 170 is attached by the floor bracket attachment 160, and the air conditioner 100 is attached to the floor by the spacer 170. That's fine.
