That is, in FIG. 1, 1 is a main body installed inside the ceiling A, and 2 is an exposed ceiling surface having an air inlet 3 in the center and air outlets 4 on both sides, as shown in FIG. A panel, 5, is a filter 6 provided above the suction port 3, a filter 6 is provided above the air outlet 4,
A Luha device is provided at 4 to adjust the air flow of the blown air; 7 is an inner frame provided within the main body 1 and partitions the suction port 3 and the air outlets 4a and 4b; 7a and 7b are formed within the main body 1; The air sucked in from the suction port 3 is an air ventilation path that communicates the suction port 3 with the air outlets 4, 4, and the air passes through the inside of the inner frame 7 and rises. The outer ventilation passage 7b descends through the gap with the body 7 and reaches the air outlet 4, 4.
It is composed of. Reference numeral 8 denotes a blower located above the suction port 3 and provided in the inner ventilation passage 7a;
10 is a heat exchanger located further above the blower 8 and provided in the inner ventilation passage 7a, and 10 is a heat exchanger 9.
A dew pan is provided between the air blower 8 and the air blower 8, and a predetermined ventilation space is provided between the devices 8 to 10.
11 is a condensation tray 10 for collecting condensed water generated in the heat exchanger 9.
12 is a discharge port for discharging the drain collected in the dew pan 10 to the outside;
A drain pipe (not shown) is connected. 1
Numerals 3 and 14 are piping connection ports that connect inlet side piping and outlet side piping (not shown) for supplying cold water or hot water to the heat exchanger 9. Reference numeral 15 denotes a sealing material for adjusting the gap between the exposed ceiling panels 2 when attached to the main body 1 and for sealing the leakage of cold or hot air flowing in the air path.

With this configuration, the air outlets 4, 4 are formed on both sides of the exposed ceiling panel 2, so the flow of air blown into the room from the air outlets 4, 4 is as shown by the arrows in Figure 1. As shown in , there are two routes, and the area that can be air-conditioned is widened.
Comfortable air conditioning without uneven indoor temperature can be obtained, and the arrangement of the air outlets 4 and 4 with respect to the air inlet 3 of the exposed ceiling panel 2 is symmetrical, so that the space between the lighting fixtures arranged symmetrically on the ceiling surface can be improved. It is used because it harmonizes with the lighting equipment even when installed in the interior, and does not cause any problems with the interior. However, when the blower 8, the dew pan 10, and the heat exchanger 9 are sequentially arranged upward from the suction port 3, the dew pan 10 is positioned approximately in the center of the inner ventilation passage 7a, so the blower 8 and dew saucer 1
0 and between the dew pan 10 and the heat exchanger 9, a predetermined ventilation space must be provided, respectively.
Furthermore, since a predetermined ventilation space is required above the heat exchanger 9 that extends from the inner ventilation passage 7a to the outer ventilation passage 7b, the height of the main body 1 becomes extremely high, and the ceiling height is relatively low. When the height of the main body 1 is low, there is a restriction that it cannot be installed in the ceiling in relation to the height of the main body 1, and the inner frame 7 has a double structure of inner and outer ventilation passages 7a, 7b.
must be provided, making the configuration complicated.

This invention was made in order to eliminate the drawbacks of the conventional example described above.

An embodiment of this invention will be described below.

Reference numeral 26 denotes a partition plate attached to one end of the blower stand 25, which, together with the blower stand 25, divides the upper part of the main body 1 into a suction side passage 27 and an outlet side passage 28. A heat exchanger 29 faces the blowing surface 24a of the blower 24 on the blowing side passage 28 side and is fixed to the main body 20 via a mounting plate 30, and its suction surface 29a is connected to the upper wall 20 of the main body 20.
It has a predetermined angle θ ₂ with respect to a. Therefore,
The blowing surface 24a of the blower 24 and the suction surface 29a of the heat exchanger 29 are arranged at a predetermined angle θ ₃ , for example, 50° to 90°. 31 and 32 are cold and hot water inlets and outlets of the heat exchanger 29, 33 is a dew pan provided below the heat exchanger 29 and has a discharge port 33a, and 34 is a gap between the blower stand 25 and the lower end of the heat exchanger 29. This is a shielding plate that prevents the air blown from the blower 24 from bypassing the heat exchanger 29 and guides the dew generated in the heat exchanger 29 to the dew pan 33 . Reference numeral 35 denotes a chamber block molded separately from the main body 20, and this chamber block is constructed as shown in FIG. In the same figure, 36 is an upper block molded from foamed resin such as expanded polystyrene, and an outer wall 37 of a predetermined height is provided on the periphery, and has a through hole 38 in the center.
An inner wall 39 having the same height as the outer wall 37 is provided around the periphery of the through hole 38, and an air passage 40 is formed around the through hole 38 by the inner and outer holes 37 and 39. Further, the upper block 36 has an air inlet 41 in an elongated shape that projects upward, and has a communication passage 42 that communicates the air inlet 41 with an air passage 40 on one side of the through hole 38 . 43 is a lower block, which, unlike the upper block, is molded from sheet metal, and is similar to the upper block 3.
Reference numeral 6 covers the air passage 40, and has an air inlet 44 equivalent to the through hole 38 of the upper block 36 in the center, and an air outlet 45 communicating with the air passage 40 on both sides. Part block 36, 4
When assembling 3, the inner and outer walls 37, 3 of the upper block 36
9 a flange portion 37a extending outward from the lower surface;
The substantially U-shaped mounting bracket 60 shown in FIG.
The chamber block is assembled as shown in FIG. Can be assembled. As shown in FIG. 3, this chamber block 35 is moved vertically through a sealing material 49 to the outlet of the outlet side passage 28 formed by the partition plate 26 and the main body 20 using the peripheral wall of the air inlet 41 as a guide. Slidably mounted. Therefore, a suction chamber C is formed within the through hole 38 of the chamber block 35 and the air inlet 44.
Further, the air blown from the blow-out side passage 28 flows through an air inlet 41, a communication passage 42, as shown by the arrow in FIG.
A series of blowing chambers D leading to each air passage 40 and air outlet 45 are formed. 50 is a filter installed in the suction chamber C. Reference numeral 51 designates a ceiling exposed panel constructed almost in the same way as the conventional one shown in FIG. 2, but differs from the conventional one in the following points. That is, the connecting plate 52 of the exposed ceiling panel 51 has a screw hole 53 and a lower block 4 for connecting with the lower block 43 of the chamber block 35.
3 and the main body 20 are provided with an escape hole 54, and this ceiling exposed panel 51
When connecting with the lower block 43, the mounting screw 56 is inserted into the screw hole 53 and the nut 55 fixed to the lower block 43, and when assembled together, the blow-off chamber D and the blow-off ports 4, 4 communicate with each other. .
After installing this assembly and installing the chamber block 35 on the outlet of the outlet side passage 28 as described above,
Insert a long adjustment screw 59 into the escape hole 54 of the exposed ceiling panel 51, the screw hole 57 of the lower block 43, and the nut 58 fixed to the side of the main body 20.
Assemble in one piece.

When installing the air conditioner configured in this way, the installation position is within the ceiling A using the hanging bolts 22 and nuts 23, but the exposed ceiling panel 51 is placed in contact with the lower surface of the ceiling A as shown in FIG. Adjust the adjustment screw 59 according to the height inside the ceiling A to install it next to each other.
It can be adjusted by tightening or loosening. At this time, the chamber block 35 also moves together with the exposed ceiling panel 51, but the sealing material 49 maintains the seal with the outlet of the air outlet passage 28. In addition, since the upper chamber block 35 of the chamber block 35 is molded from foamed resin, and the lower chamber block 43 is molded from sheet metal, the stress generated due to the difference in elongation due to the difference in the coefficient of thermal expansion is eliminated by the mounting bracket 60 being molded from the upper block. 36 flange portion 37
Since a and 39a can be slid, they are firmly fixed without affecting them all. On the other hand, when indoor air conditioning is performed, the indoor air is fed to the exposed ceiling panel 5 as shown by the arrow in Fig. 3.
The air is blown out from the blowing surface 24a through the suction port 3 of No. 1, the suction chamber C filter 50, and the suction port 24c of the blower 24. This blown air is supplied to the upper wall 20 of the main body 20.
a, the suction surface 29a of the heat exchanger 29
The heat exchanger 29 is almost uniformly fed into the heat exchanger 29, thereby increasing the heat exchange efficiency in the heat exchanger 29. Then, it becomes cold air or hot air in the heat exchanger 29, passes through the blow-out side passage 28 and the air inlet 41, and reaches the blow-out chamber D. Inside this air flow passage, it branches into each air flow passage 40 and circulates, and each blow-out port 4 , 4 into the room, the room can be uniformly air-conditioned.

As described above, in this design, a chamber block is interposed between the main body and the exposed ceiling panel, which is an integrally molded chamber with a suction chamber in the center and a blowout chamber consisting of an air passage around the suction chamber, so the structure of the inflow passage within the main body is simple. becomes. In addition, since each chamber is molded from foamed resin, it is easy to manufacture, and there is no need to provide a separate insulation material at the bottom of the main body, allowing for a compact overall structure without compromising the uniformity of temperature distribution in the room. . Furthermore, although the upper block constituting the chamber block is made of foamed resin and the lower block is made of sheet metal,
The assembly of both blocks can be firmly screwed and fixed using the mounting bracket.
