The bent upper plate 3 is superimposed at the respective bent portions 2a to 2c, 3a, and 3b, and assembled by spot welding or the like into a substantially U-shaped cross section, especially the lower end side bent portions 2d of the side plates 2. is inclined upward from approximately the center toward the front side of the frame 1, and a through hole 4 is provided at the overlapping portion on the upper surface side for inserting and fixing a suspension bolt (not shown) to the ceiling. It is being A heat exchanger 5 is housed in one half of the front side of the frame 1, and is supported by a support plate 6 fixed between the side plates 2. Reference numeral 7 denotes a blower that is housed in one half of the rear side and blows air to the heat exchanger 5. Fixed. 9 is heat exchanger room A
It is a cut-and-raised piece cut and raised outward in a trapezoidal shape at approximately the center of the side and rear side plates, that is, the both side plates 2,
By this cutting and raising, a cutout space 10 equivalent to the cutout and raised piece 9 is formed in both side plates 2, and a square hole 11 is bored at a predetermined height position of the cut and raised piece 9. ing. Reference numeral 12 denotes a drain pan that is formed to become deeper from the front side to the rear side of the frame 1 and covers the lower surface of the heat exchanger. Contains the drain generated in the Also, this drain pan 12
The front end of the drain pan 12 rises substantially perpendicularly from the bottom surface of the drain pan 12, and has a horizontal surface 13 formed by bending its edge horizontally. and drain pan 1
2 rises along the slope of the trapezoidal notch 10 at the rear end thereof, and has a discharge port 14 at the lower part of the rising surface, forming a dish-like shape as a whole.
15 is a mounting piece provided on the rear rising surface of the drain pan 12 so as to correspond to the square hole 11 of the cut and raised piece 9; 16 is a mounting piece provided on the front side of the drain pan 12 corresponding to the bent portion 2a of both side plates 2. This is a mounting plate that is mounted upright on the inner bottom surface of the drain pan 12, and is formed to have a width equal to or greater than the width of the frame 1. Therefore, the drain pan 12 is attached to the frame 1.
When mounting on the bottom surface, cut and raise the mounting piece 15 and attach the piece 9.
When inserted into the square hole 11 of the drain pan 12, the rear end of the drain pan 12 is located within the notch space 10, and the mounting plate 16 and the bent portions 2a of the side plates 2 are overlapped at a predetermined position and the tuft pin screw 17 is inserted. If you fix it with
The bent portions 2d of both side plates 2 are in contact with the inner bottom surface of the support plate 6, and both ends of the support plate 6 are connected to the drain pans 12, respectively.
and the blower stand 8 to prevent ventilation from bypassing. Reference numeral 18 denotes an upper casing fixed at the upper part of the front side of the frame 1 along the bent portion 3a of the upper plate 4, and is formed to be larger in width than the drain pan 12. 19 is located at the lower front side of the frame 1, one end is connected to the mounting plate 16, and the other end is connected to the both side plates 2.
The lower casing is fixed to the bent portion 2d, has the same width as the upper casing, and covers the lower front and lower surface of the drain pan 12. Reference numeral 20 denotes an air outlet grill installed between the step portions 21 and 22 of the upper and lower casings 18 and 19, and the air outlet grill located on the right side in FIG. 1 is formed in a blind shape. 23 is a stepped portion 22 of the lower casing 19 and a blowout grille 20
and the lower end of the outlet grille 20.
The upper end of the outlet grille 20 is brought into close contact with the stepped portion 21 of the upper casing 18 by the elastic force of this insulation cushion. 24 is a heat insulating material inserted between the horizontal surface 13 of the drain pan 12 and the lower surface of the stepped portion 22 of the lower casing 19, which prevents heat conduction from the outlet grille 20 side to the lower casing 19 side, and prevents heat conduction to the lower casing 19. Prevents condensation. 25 is a heat insulating material formed between the upper and lower casings 18 and 19 and installed in the air passage leading from the heat exchanger room A to the outlet grille 20; 26 is a lower panel that covers the lower surface of the frame 1 on the side of the blower room B; , has a suction grill 27.

Reference numerals 28 and 29 refer to two types of reinforcing spacers, large and small, which are removably attached to the rear of the frame 1 and extend outward from both side plates 2. Reference numerals 30 refer to both ends of the upper and lower casings 18 and 19, and the spacers 28 and 29.
A piping space 31 and an electrical component space 32 are formed between the both side casings 30 and the both side plates 2. For example, when installing an air conditioner with right piping, as shown in Fig. 1, install the large spacer 28 on the right side and the small spacer 29 on the left side, and also shift the upper and lower casings 18 and 19 to the right side. When installed, a large piping space 31 will be formed on the right side and a small electrical component space 32 will be formed on the left side. The air conditioner configured in this way is suspended from the ceiling via the through hole 4 of the frame 1 and suspension bolts (not shown), and the blower 7
During operation, indoor air is sucked in through the suction grille 27, exchanges heat with the cold water flowing inside the heat exchanger 5, and is blown out from the outlet grille 20 as cold air. The air sent into A is guided to the heat exchanger 5 by the support plate 6 without bypassing the heat exchanger 5, and
The cold air from the heat exchanger 5 is transferred to the support plate 6 and the drain pan 1.
2 bottom surface and the mounting plate 16, the outlet grille 20 is cooled without leaking to the outside, and condensation occurs on the outlet grille 20, but the outlet grille 20
The dew water flowing down from the outlet reaches the lower part of the outlet grill 20, but since the front corner of the outlet grill 20 is rounded, the dew water flows down to the lower part of the outlet grill 20.
The groove 23 of the insulation cushion 23 wraps around the lower end of the
Flows down into a. Since the dew water contained in the groove 23a is small in quantity, it evaporates naturally when the air conditioner is stopped due to thermo-operation or the like. Further, normally, a portion of the cold air blown out from the outlet grille 20 generates turbulent flow near the lower end of the outlet grille 20 and comes into direct contact with the lower casings 18 and 19, causing dew condensation. Since there is a distance between the blow-off grille 20 and the lower casing 19 by the height of the heat-insulating cushion 23, the cold air does not come into direct contact with the lower casing 19. Also, due to the heat insulating action of the heat insulating cushion 23, the air outlet grille 20
Furthermore, heat conduction from the drain pan 12 to the lower casing 19 is prevented by the heat insulating material 24, so that no dew condensation occurs on the lower casing 19. In addition, the drain pan 12 accommodates dew water that has flowed down from the heat exchanger 12, and as the weight increases, the drain pan 12 tends to bend in the width direction, but the mounting plate 16 is fixed to the inner bottom surface of the drain pan 12 in the width direction. Since the mounting plate 16 also serves as a reinforcement and closes the lower part of the frame 1, dew water in the drain pan 12 is not blown away outside the drain pan 12 by cold air.

As described above, in this invention, a cut and cut piece is formed at a predetermined position on both sides of the frame and has a through hole at a predetermined height position, and one side of the drain pan is attached to the frame. Since it is fixed with screws to the ends of both side plates, as a result, one side portion of the drain pan is housed in the notch space formed by the above-mentioned cut-and-raised portion. Therefore, the height of the air conditioner can be reduced by the amount accommodated in the notch space, and the air conditioner can be made thinner. Since one side of the drain pan is supported by the piece, there is no need to provide a separate support member, and the structure is simple. Further, the drain pan can be fixed to the frame simply by inserting one side of the drain pan into the through hole of the cut-and-raised piece and screwing the other side of the drain pan to the frame, which simplifies the operation.
