Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a ceiling-embedded air conditioner.

(Prior Art) An example of a conventional ceiling-embedded air conditioner is shown in FIG.

In FIG. 3, reference numeral 1 denotes a main body, which is suspended from a slab 4 via a mounting piece 2 and a hanging rod 3. 5 is an exposed panel with an inlet 6 and an outlet 7 on both sides thereof.
a and 7b, attached to the ceiling 8 and covering the lower surface of the main body 1. A partition plate 9 divides the inside of the main body 1 into a suction side chamber 10 and an outlet side chamber 11. Reference numeral 12 denotes a fan, which is disposed within the suction side chamber 10. 1
Reference numeral 3 denotes a heat exchanger, which is disposed within the blow-off side chamber 11. A drain pan 14 is disposed below the heat exchanger 13. Reference numeral 15 denotes a chamber block, which is disposed in the lower part of the main body 1 and has a suction passage 16 that communicates the suction port 6 with the suction side chamber 10, and a blowout passage 17 that communicates the blowout ports 7a and 7b with the blowout side chamber 11. Reference numeral 18 indicates a filter disposed within the blowing passage 16, and reference numeral 19 indicates a wind shielding plate.

During operation of this air conditioner, by driving the fan 12, indoor air enters the suction side chamber 10 through the suction port 6, suction passage 16, and filter 18 as shown by the white arrow, and enters the fan 12. As a result, it is energized and blown out into the blow-out side chamber 11, and the heat exchanger 13 is energized.
After being cooled or heated in this process, it is blown out into the room from the blow-off ports 7a and 7b via the blow-off passage 17.

(Problem to be solved by the invention) In the above conventional ceiling-mounted air conditioner,
The mounting height of the main body 1 can be adjusted to some extent by raising or lowering the position of the nut 20 screwed onto the hanging bolt 3, but if the drain height needs to be increased, etc. As shown in the main body 1
Adding the auxiliary frame 21 to the lower end of the partition plate 9
Since it is necessary to replace the partition plate 22 with a long partition plate 22,
It is necessary to remove the chamber block 15 from the main body 1, and furthermore, it is necessary to interpose a sealing material 23 between the chamber block 15, the partition plate 22, and the auxiliary frame 21, so there is a problem that it takes a lot of effort and time. .

Furthermore, since the chamber block 15 is separated from the fan 12, the air pressure at its inlet changes from that at the one in FIG. There was a problem that bias occurred.

(Means for Solving the Problems) The present invention was proposed to solve the above problems, and its gist is to provide a main body buried in the ceiling, a suction side chamber and an outlet side chamber inside the main body. an exposed panel that has an inlet and an outlet on both sides thereof and is attached to the ceiling and covers the lower surface of the main body, and is arranged at the lower part of the main body and communicates the inlet with the suction side chamber. In a ceiling-embedded air conditioner, the ceiling-mounted air conditioner is equipped with a chamber block that limits a suction passage that communicates the air inlet with the air outlet and an air outlet that communicates the air outlet with the air outlet. In the ceiling-embedded air conditioner, an auxiliary frame body having an air outlet passage communicating with the air outlet passage of the chamber block is removably disposed between the exposed panel and the chamber block.

(Function) Since the present invention has the above configuration, when it is necessary to extend the vertical length of the air conditioner, an auxiliary frame is interposed between the chamber block and the exposed panel. Then, the air sucked in from the suction port of the exposed panel passes through the suction passage of the auxiliary frame and the suction passage of the chamber block, enters the suction side chamber, and is sucked into the fan, and the air blown out from the fan flows through the heat exchanger. The air then enters the air outlet passage of the chamber block, is divided evenly to the left and right, and then passes through the air outlet passage of the auxiliary frame and is blown into the room from the air outlet of the exposed panel.

(Embodiment) An embodiment of the present invention is shown in FIGS. 1 and 2.

Between the exposed panel 5 and the chamber block 15, there is a suction port 6 of the exposed panel 5 and the chamber block 1.
A suction passage 25 communicates with the suction passage 16 of No. 5, and an air outlet passage 2 communicates between the air outlet ports 7a, 7b of the exposed panel 5 and the air outlet passage 17 of the chamber block 15.
An auxiliary frame body 27 having 6a and 26b is removably interposed.

Details of the assembly structure of the auxiliary frame body 27 are shown in FIG.

The chamber block 15 has a screw 28 passing through a hole 15b formed in the flange 15a of the main body 1.
It is fastened to the main body 1 by screwing into a nut 29 welded to the flange 1a.

The main body frame 27 has a screw 29 passing through a hole 27b formed in the flange 27a of the flange 15a.
It is fastened to the chamber block 15 by screwing into a screw hole 15c drilled in the chamber block 15.

The exposed panel 5 is fastened to the auxiliary frame 27 by screwing a screw 30 passing through a hole 5b formed in the flange 5a into a nut 31 welded to the flange 27c of the auxiliary frame 27.

A suction passage 6 is defined between a pair of inner walls 5c and 5d of the exposed panel 5, and this suction passage 6 communicates with a suction passage 25 defined between a pair of inner walls 27d and 27e of the auxiliary frame 27. . Further, the right outlet 7a is limited between the right outer wall 5e and the inner wall 5d of the exposed panel 5, and the right outlet 7a is connected to the auxiliary frame 2.
7 and communicates with a right blowing passage 26a defined between a right outer wall 27f and an inner wall 27e. Further, the left outlet 7b defined between the left outer wall 5f and the inner wall 5c of the exposed panel 5 communicates with the left outlet passage 26b defined between the left outer wall 27g and the inner wall 27d of the auxiliary frame 27. There is.

The rest of the structure is similar to the conventional one shown in FIGS. 3 and 4, and corresponding members are given the same reference numerals.

During operation of this air conditioner, indoor air flows from the air outlet 6 to the suction passages 25 and 16 as shown by the white arrow.
After passing through the filter 18 to remove dust, the air enters the suction side chamber 10 and is sucked into the fan 12 from there. The air energized by the fan 12 is heated or cooled by passing through the heat exchanger 13, and then passes through the chamber block 15.
The flow enters the blowout passage 17 and is divided evenly to the left and right,
One of them is blown into the room from the outlet 7a through the outlet passage 26a, and the other is blown into the room from the outlet 7b through the outlet passage 26b.

(Effect of the invention) In the present invention, when it is necessary to extend the vertical length of the air conditioner, the suction passage that communicates the suction opening of the exposed panel with the suction passage of the chamber block and the air outlet of the exposed panel An auxiliary frame body having a blow-off passage communicating the blow-off passages of the chamber block is interposed between the exposed panel and the chamber block.

Therefore, there is no need to replace the partition plate as in the conventional case, and therefore there is no need to remove the chamber block from the main body, and the sealing material between the chamber block, partition plate, and main body can be used as is. In this way, it becomes possible to easily and quickly extend the vertical length of the air conditioner. In addition, since the distance between the chamber block and the fan does not change, the blown air can be divided evenly to the left and right by the chamber block, and therefore the air can be blown equally into the room from the left and right outlets. Prevents uneven indoor air temperature.
