It is something to do.

An embodiment of this invention will be described below.
1 and 2, reference numeral 1 denotes a frame of a predetermined width that forms the framework of the air conditioner, and as shown in FIG. The bent upper plate 3 is assembled at the bent portions 2a to 2c, 3a, and 3b by spot welding or the like to have a substantially U-shaped cross section, especially at the lower bent portions 3d of the side plates 2. is sloped upward from the center toward the front side of the frame 1, and a hole 3d' is bored near the center, and a bolt for hanging to the ceiling is provided at the overlapping part on the top side. A through hole 4 is provided for inserting and fixing a (not shown). 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. 8a is a rib provided on this blower stand 8. Reference numerals 9 and 11 indicate cut-and-raised pieces cut and raised toward each side at approximately the center of both side plates of the rear side of the heat exchanger chamber A side, that is, the both-side plates 2; Two square holes 9a and 9b are formed in the upper and lower sides, and a hole 11a is formed in the cut and raised piece 11. Reference numeral 12 denotes a drain pan that is formed so as to become deeper from the front side to the rear side of the frame 1 as shown in Figs. The drain generated in the heat exchanger 5 and both side plates 2 is accommodated. 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 notch space 10, and a discharge port 14 is provided at the bottom of the rising surface.
It has a dish-like shape as a whole. 15 is a mounting piece provided on the rising surface of the rear side of the drain pan 12 so as to correspond to the square holes 9a and 9b 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, insert the mounting piece 15 into the square hole 9b of the cut and raised piece 9 on the drain piping side, and insert the mounting piece 15 into the square hole 9a of the cut and raised piece 9 on the opposite side of the drain pipe. By overlapping the mounting plate 16 and the bent portions 2a of the side plates 2 at a predetermined position and fixing them with the tuft pin screws 17, the drain pan 12 can be installed with a downward slope from the side opposite to the drain pipe to the side of the drain pipe. Become. At this time, the support plate 6 is as shown in FIG.
Holes 6a, 6b, and 6c are drilled on both sides, so on the drain piping side, the hole 6a is cut out and overlapped with the hole 11a of 11 and screwed, and on the opposite side of the drain piping, the hole 6b is When the holes 11a overlap and are screwed, this support plate 6 will also be installed with a downward slope from the side opposite to the drain pipe to the side of the drain pipe. At this time, the support plate 6 is also fixed to the heat exchanger 5 with screws using the holes 6c.

When the sealing material 33 is attached to the side plate bent part 2d on the drain pipe side in such a state, the lower side of the frame includes the support plate 6, the drain pan 12, the side plate bent part 2d on the side opposite to the drain pipe, and the sealing material on the drain pipe side. 3
3 and the mounting plate 16 at the front of the drain pan,
The space between the blower stand 8 and the support plate 6 is maintained by the rib 8 provided on the blower stand 8 even when the support plate 6 is inclined in the width direction of the main body.
7a, the upper end surface of the support plate 6 is always in contact with the blower stand 8 as shown in FIG. 7, so that the inside of the frame is in a sealed state and bypass of ventilation can be prevented.

At this time, the sealing material 33 is attached to the L-shaped sheet metal part 3.
It has a structure in which a cushion material 33b with sufficient elasticity is attached to the cushion material 33a, and a hole is provided near the center of the cushion material 33b. It can be easily attached to the frame by overlapping and screwing with the tuft pin screws 17.

Also, when changing piping, attach the drain pan 12 and support plate 6 to the frame at a reverse slope, and attach the sealing material 33 to the frame.
By removing the tatsupin screw 17 and replacing it with the opposite frame lower bent portion 2d, the inside of the frame can be easily sealed again.

Moreover, if this sealing material 33 is a sealing material 34 made of a rubber molded product as shown in FIG.
As shown in 3, the sheet metal part 33a and the cushion material 33b
There is no need for pasting it, and there is no need to use screws when fixing it to the frame, making the installation process easier.

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. A lower casing 19 has one end fixed to the mounting plate 16 and the other end fixed to the bent portion 2d of both side plates 2 at the lower front side of the frame 1. The lower casing 19 is formed to have the same width as the upper casing, and is fixed to the lower front side of the drain pan 12 and the lower casing 19. It covers the bottom surface. 20 is the upper and lower casing 18,1
9, the outlet grill located on the right side in FIG. 1 is formed in a blind shape. 23 is lower casing 1
The L-shaped heat insulating cushion is inserted between the step portion 22 of No. 9 and the lower end of the outlet grille 20, and has a groove 23a for receiving dew water flowing down from the outlet grille 20. 20 to the step part 2 of the upper casing 18.
It is closely tied to 1. 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 from the heat exchanger room A to the blowout grille 20; 26 is a lower panel that covers the lower surface of the frame 1 on the side of the blower room B; It 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 passed through the support plate 6 and the drain pan 12.
The outlet grille 20 is cooled by the bottom surface, the sealing material 33, and the mounting plate 16 without leaking to the outside, and dew condensation occurs on the outlet grille 20, but the dew water flowing down from the outlet grille 20 reaches the lower part of the outlet grille 20. However, since the front corner of the outlet grille 20 is rounded, the dew water flows around the lower end of the outlet grille 20 and prevents the heat insulating cushion 2.
3 into the groove 23a. 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. In addition, normally, a part of the cold air blown out from the outlet grille 20 causes turbulence near the lower end of the outlet grille 20 and directly contacts 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 cushion 23, the cold air does not come into direct contact with the lower casing 19. Further, the heat insulating action of the heat insulating cushion 23 prevents heat conduction from the outlet grille 20 to the lower casing 19, and the heat insulating material 24 prevents heat conduction from the drain pan 19.
2 to the lower casing 19 is prevented,
Condensation does not form on the lower casing 19. Also,
The drain pan 12 accommodates dew water flowing 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, the drain pan 12
The dew water inside is not blown away to the outside of the drain pan 12 by the cold wind.

As described above, in this invention, when the drain pan and support plate are installed on the frame with a slope, the gap that occurs between the bottom of the frame and the bottom of the drain pan can be filled by attaching a removable sealing material to the frame by bending the bottom of the frame. Since it can be sealed by attaching it to the lower part of the frame, even when changing piping, simply install the drain pan and support plate on the opposite slope, and then replace the sealing material with the bent part of the lower part of the frame on the opposite side. It is now possible to seal the frame, and there is no longer a need for special parts to seal the bottom of the frame when changing piping.
