DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, specific embodiments of the ceiling-embedded air conditioner of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a transparent side view showing the above embodiment, and FIG. 2 is a partially cutaway perspective view showing the structure of the chamber 4. Explaining the above embodiment with reference to both drawings, the inside of the casing 1 is divided by a fan mounting plate 16 into an air suction chamber 7 in which the fan 2 is arranged and an air blowing chamber 6 in which the heat exchanger 3 is arranged. The chamber 4 is arranged below the chamber 4. The chamber 4 is provided with a first outlet 11 on one side and a second outlet 12 on the other side opposite to the first outlet 11 side. Is provided with a wind direction guide 10 that bends in an L-shape toward the second outlet 12 side and communicates with the air outlet chamber 6, while an intake passage 8 is provided in the central portion and the air intake chamber 7 is provided. Is in communication with. The first outlet 11 side and the second outlet 12 side are communicated with each other by air guide passages 9a and 9b provided on both sides of the suction passage 8. By the way, the configuration up to this point is substantially the same as the configuration of the conventional example. However, in the ceiling-embedded air conditioner according to the present embodiment, in addition to the above, one of the side portions provided with the first outlet 11 and the side portions provided with the second outlet 12 intersects (orthogonally) with. The third outlet 13 is provided on the side of the above, and the fourth outlet 14 is provided on the other side opposite to this. Also, the outer wall 18 of the air guide passages 9a, 9b
Ventilation openings 15a and 15b are provided in a and 18b, and further, the wind direction guide 10 is provided such that both ends 10a and 10b thereof are arranged outside the outer walls 18a and 18b. Further, another air guide passage, that is, a central passage 9c is provided so as to cross the central portion of the suction passage 8, and the width of the central passage 9c becomes gradually wider toward the second outlet 12. The expanded part 17 is
It is provided in communication with the outlet 12.

Next, the operation of the ceiling-embedded air conditioner configured as described above will be described. First, by operating the fan 2, the room air R is sucked into the air suction chamber 7 in the casing 1 from below the ceiling 20 through the suction passage 8. The indoor air R is heat-exchanged by the heat exchanger 3 to become the conditioned air W, and then is pressure-fed from the air blowing chamber 6 to the chamber 4. The conditioned air W pressure-fed to the chamber 4
Is partially blown out into the room below the ceiling 20 from the first outlet 11 provided directly below,
The remaining air B, C, D bends in an L shape and is a wind direction guide 1
It is deflected toward the second outlet 12 according to the shape of 0. At this time, since both ends 10a, 10b of the wind direction guide 10 are arranged outside the outer walls 18a, 18b of the air guide passages 9a, 9b, the conditioned air B deflected toward the second outlet 12 is formed. A part B of C, D flows through a gap formed outside the outer walls 18a, 18b, and is mainly the first blower of the third blower outlet 13 and the fourth blower outlet 14.
The air is blown into the room below the ceiling 20 from the portion near the air outlet 11. Also, the outer walls 18a, 18 of the air ducts 9a, 9b are
Passage openings 15a and 15b are provided in b. Therefore, after being deflected by the wind direction guide 10, a part C of the conditioned air C, D that has circulated in the air guide passages 9a, 9b will flow from the air passage openings 15a, 15b into the air guide passages 9a, 9b. It leaks to the outside of 9b and is blown out into the room below the ceiling 20 mainly from the portions of the third outlet 13 and the fourth outlet 14 near the second outlet 12. Then, all of the remaining conditioned air D flowing through the air guide passages 9a and 9b and the conditioned air D flowing through the central passage 9c are included in the second outlet 1
2 is blown into the room below the ceiling 20.

As described above, in the ceiling-embedded air conditioner according to this embodiment, air conditioning is performed from the first to fourth outlets 11 to 14 provided on the four sides of the chamber 4 to the room below the ceiling 20. Air A to D is blown out. At this time, since the conditioned air A is blown from the upper side to the lower side of the first outlet 11 along the gap formed on the back side of the wind direction guide 10, it is substantially uniform over the entire length of the first outlet 11. It is possible to secure the conditioned air A having a large flow rate. Also the second
Regarding the air outlet 12, conventional air guide passages 9a, 9b
In addition to the central passage 9c, the central passage 9
An expanded portion 17 is provided at c. Therefore, the conditioned air D having a substantially uniform flow rate can be secured over the entire length of the second outlet 12. Further, with respect to the third outlet 13 and the fourth outlet 14, mainly the first outlet 11
The conditioned air B blown out from the side and the conditioned air C blown out mainly from the second outlet 12 are blown out in harmony. Therefore, the conditioned air B, C having a substantially uniform flow rate can be secured over the entire length of the third outlet 13 and the fourth outlet 14 as well.
That is, by installing this ceiling-embedded air conditioner in the ceiling 20 located substantially in the center of the room, it is possible to obtain an air conditioning environment in which the comfort of use is not impaired at any position in the room. . For example, when the ceiling-embedded air conditioner is applied to a hospital room, the conditioned air can be blown out substantially uniformly to all the beds indicated by P to U in FIG. The expected comfort of use can be obtained at the location.

Although specific embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention. For example, the conditioned air B at the second outlet 12
In order to ensure the uniformity of the distribution, the expansion portion 17 is provided in the central passage 9c (see FIGS. 2 and 3).
It may be provided in the air guide passages 9a and 9b as shown in FIG.

【The invention's effect】

In the ceiling-embedded air conditioner according to the first aspect, the conditioned air is blown out from the first to fourth outlets, that is, the side portions on the four sides of the chamber. Therefore, by attaching this to the substantially central position of the room, the conditioned air can directly reach the entire room, and the comfort of use can be improved.

Further, in the ceiling-embedded air conditioner according to the second aspect, the conditioned air flowing outside the air guide passage is also blown out below the ceiling from the third outlet and the fourth outlet. Therefore, the amount of air blown out from these air outlets can be secured, and it becomes possible to further improve the comfort of use.

Furthermore, in the ceiling-embedded air conditioner according to the third aspect of the invention, the amount of conditioned air blown out from the second outlet is secured,
It is possible to further improve the use comfort.

In the ceiling-embedded air conditioner according to the fourth aspect, the distribution of the conditioned air blown from the second outlets can be made uniform to further improve the use comfort.
