[Detailed Description of the Invention] The purpose of this invention is to improve workability, especially when changing the direction of drain piping, regarding the frame structure of a ceiling-suspended air conditioner and the mounting dimensions of a drain pan.

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 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 there is a through hole 4 in the overlapping part on the upper surface side for inserting and fixing a suspension bolt (not shown) to the ceiling.
is provided. 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. 9 and 11 are 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, both side plates 2;
Two square holes 9a and 9b, upper and lower, are bored at a predetermined height position of this cut and raised piece 9, and a hole 1 is formed in the cut and raised piece 11.
1a is bored. 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 as shown in Figs. 4 and 5, and covers the lower surface of the heat exchanger, and has a width larger than the width of the frame 1. It is formed to accommodate the drain generated in the heat exchanger 5 and both side plates 2. The front end of the drain pan 12 rises substantially vertically 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 rear rising surface of the drain pan 12 so as to correspond to the square holes 9a, 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 pan piping side, and insert the mounting piece 15 into the square hole 9b of the piece 9 on the side opposite to the drain pipe.
After inserting it into the drain pan 12, the mounting plate 16 and the bent portions 2a of the side plates 2 are overlapped at a predetermined position and fixed with the tuft pin screws 17. It will be installed. At this time, the support plate 6 is 6 as shown in FIG.
Holes a, 6b, and 6c are drilled on both sides, so on the drain piping side, the hole 6a overlaps with the hole 11a of 11 and is screwed, and on the anti-drain piping side, the hole 6b 11a and are screwed together, 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 uses the hole 6c,
It is also fixed to the heat exchanger 5 with screws.

In such a state, when the sealing material 33 is attached to the side plate bent part 2d on the drain pipe side, the lower side of the frame is the support plate 6, the drain pan 12, the side plate bent part 2d on the side opposite to the drain pipe, and the seal on the drain pipe side. Material 3
3 and the mounting plate 16 at the front of the drain pan, and the space between the blower stand 8 and the support plate 6 is provided on the blower stand 8 even when the support plate 6 is inclined in the width direction of the main body. Due to the ribs 8a, 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 sealed and bypass of ventilation can be prevented.

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.

Reference numeral 19 denotes a lower casing at the lower front side of the frame 1, with one end fixed to the mounting plate 16 and the other end fixed to the bent portion 2d of the side plates 2. The lower casing 19 is formed to have the same width as the upper casing, and is located at the lower front side of the drain pan 12. and covers the lower 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 stepped 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. Reference numeral 24 denotes 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 transfer 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; 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. 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. A blowout grille 20 corresponding to the height of the insulation cushion 23
Since there is a distance between the lower casing 19 and the lower casing 19, the cold air does not come into direct contact with the lower casing 19.
In addition, heat conduction from the outlet grille 20 to the lower casing 19 is prevented by the heat insulating action of the heat insulating cushion 23, and heat conduction from the drain pan 12 to the lower casing 19 is further prevented by the heat insulating material 24, resulting in condensation on the lower casing 19. There's nothing to do. In addition, the drain pan 12 accommodates dew water that has flowed down from the heat exchanger 12, increasing the weight of the drain pan 12.
2 tries to bend in the width direction, but since the mounting plate 16 is fixed to the inner bottom surface of the drain pan 12 in the width direction, it also acts as a reinforcement and closes the lower part of the frame 1. , drain pan 1
The dew water inside the drain pan 12 is not blown away by the cold wind to the outside of the drain pan 12.

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. It is fixed with screws to the ends of both side plates, and the opposite side is inserted into two square holes at different heights, upper and lower, provided in the above cut and raised piece for support, so there is no slope in the drain pan in the width direction of the main body. Moreover, the installation itself does not require a separate support member, making it simple and inexpensive. Furthermore, the blower stand is equipped with ribs, and the support plate can be installed with a slope in the width direction of the main unit in the same way as the drain pan, and the inside of the main unit can be easily sealed by adding one sealant. No special parts or work are required to change the direction.
