Description

[Detailed description of the invention] This invention relates to an improvement of an air conditioner installed inside the ceiling. This type of air conditioner was constructed as shown in FIG. That is, the first
In the figure, 20 is a box-shaped main body installed in the ceiling A, and mounting pieces 21 are provided on both sides of the main body 20. Reference numeral 22 denotes a hanging bolt embedded in the ceiling slab B. By inserting this bolt into the mounting piece 21 and tightening the nut 23, the hanging height of the main body 1 in the ceiling A is adjusted. Reference numeral 24 denotes a blower made of a Sirotskov fan that is fixed to one side of the upper part of the main body 1 via a blower stand 25, and its blowing surface 24a has a predetermined angle θ ₁ with respect to the upper wall 20a of the main body 20, and The scroll portion 24b of the fan casing is arranged inside the main body 1. 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 inner 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 side of the blowing side passage 28 and is fixed to the main body 1 via a mounting plate 30, with its suction surface 29a facing the upper wall 20a of the main body 20, It has a predetermined angle _θ2 . 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 prevents the air blown from the blower 24 from bypassing the air and removes the dew generated in the heat exchanger 29 from the dew pan 33.
This is a shielding plate that guides you. 35 is a chamber block molded separately from the main body 20, and this chamber block is constructed as shown in FIG. In the figure, reference numeral 36 denotes an upper block molded from a foamed resin such as styrofoam, which has an outer wall 37 of a predetermined height on its periphery, a through hole 38 in the center, and a peripheral edge of this through hole 38. is provided with an inner wall 39 having the same height as the outer wall 37, and has a through hole 38.
An air passage 4 is formed around the periphery by inner and outer walls 37 and 39.
0 is formed. Further, the upper block 36 has an air inlet 41 in an elongated shape that projects upward, and a communication passage 42 that communicates the air inlet 41 with an air passage 40 on one side of the through hole 38 . Reference numeral 43 designates a lower block which, unlike the upper block, is molded from sheet metal and covers the air passage 40 of the upper block 36, with an air inlet 4 equivalent to the through hole 38 of the upper block 36 in the center.
4. It has air outlet ports 45, 46 on both sides thereof communicating with the air passage 40, and the upper and lower blocks 36, 4
When assembling block 3, screw hole 4 of each block 36, 43
By inserting mounting screws 49 through holes 7 and 48, the chamber block is assembled as shown in FIG. As shown in FIG. 1, this chamber block 35 is inserted into the outlet of the outlet side passage 28 formed by the partition plate 26 and the main body 20 in the vertical direction via the sealing material 50 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, and the air blown from the outlet side passage 28 flows through the air inlet 41 and the air inlet 44 as shown by arrows in FIG. Passage 42, each air passage 4
0, a series of blowing chambers D leading to air outlets 45, 46 are formed. However, the blowout chamber formed in this way has two air outlets 45 and 46.
Since the lengths of the paths leading to the air conditioners are different, the difference in ventilation resistance results in a large difference in the amount of air coming out of the air outlets 45 and 46, which has the disadvantage of causing temperature unevenness in indoor air conditioning. It was hot.
This invention was made to eliminate the above-mentioned conventional drawbacks, and one embodiment of this invention will be described below.

In FIG. 4, reference numeral 61 denotes a resistance portion projecting downwardly from a predetermined position in the communication path 42, and is molded integrally with the chamber block 35 from foamed resin. The resistance portion 61 is shaped to block more than half of the communication path 42, and is formed at an angle of approximately 45° with respect to the air inlet 41. Therefore, the air discharged from the blower 24 flows into the air inlet 41 after passing through the heat exchanger 29, and when it passes through the communication path 42, it collides with the resistance part 61 and the direction of the air is changed as shown by the arrow in the figure. to one air outlet 46
Despite the difference in ventilation resistance due to the difference in path length, almost uniform air is blown out from the air outlets 45 and 46, and the resistance part 6
1 is made of foamed resin, so there is no condensation on that part.

As described above, in this invention, a resistance part is formed in the communication path of the chamber block, and the air is blown out almost evenly from both outlet ports of the chamber block, so it is possible to equalize the temperature distribution in the room. .
