In the figure, 12 is the unit body that is installed in the ceiling.
The unit has 12 main bodies, a blower device 13 is arranged in the center, and heat exchangers 14 are arranged symmetrically on both sides.

Number 11 is a frame of the unit main body 12 that supports the heat exchanger 14 and is a member for attaching or fixing a decorative panel, which will be described later, by appropriate means.

20 is a lower decorative panel attached to the unit main body 12 so as to be in close contact with the ceiling surface, and 21 is the lower decorative panel 20.
This is a lower decorative panel attached or fixed to the frame 11 of the unit main body 12 with an interval parallel to the lower decorative panel 2o and the lower decorative panel 21. , a blower device 13 inside the unit body 12 is located in the center of the unit body 12.
An air suction port 15 communicating with the section is open.

Further, an air blowing passage 16 partitioned by the frame 11 is formed on the outer side between the two planes of the lower decorative panel 20 and the lower decorative panel 21. The air blowing passage 16 is a blower f
Heat exchanger 14 arranged symmetrically around il13
It communicates with the outside of the decorative panel and is formed symmetrically on both sides of the decorative panel.

22 is an opening provided symmetrically on the air blowing passage 16 side of the lower decorative panel 21, and although detailed illustration is omitted, its shape is slightly shorter in length than the area in which the air blowing passage 16 is formed. The hole 22 is rectangular in length and has a width approximately equal to the distance between the upper and lower decorative panel surfaces. 23, a rotation center 23a is located at the outer end of the opening 22.
It is a horizontal blade that is rotatable and can be stopped at any position. Although detailed illustration of the shape of the horizontal blade 23 is omitted, it has a length corresponding to the length of the elongated hole in the opening, and a width slightly shorter than the interval between the upper and lower decorative panel surfaces. The horizontal blades 23 are installed as shown in FIG. 5, and the positions of the horizontal blades indicated by solid lines indicate the case where air is mainly blown vertically downward, and the positions of the horizontal blades indicated by two-dot chain lines are as follows:
This shows the case where the air is mainly blown out in the horizontal direction.

Next, the operation of the ceiling-embedded air conditioner configured as described above will be explained.

The air in the room to be air-conditioned flows through suction port 1 as shown by the arrow.
5 into the unit main body 12, blown by the blower 13, air-conditioned through the symmetrically arranged heat exchanger 14, and turned into cold or warm air into the room from the air blowing passages 6 on both sides. It's blown out.

First, during cooling, cold air is blown out from the air blowing passage 16. At this time, if the horizontal blades 23 are set to close the opening 22, most of the cold air is directed horizontally as shown by the thick dashed arrow. A portion of the air is blown out vertically downward through the opening 22 as shown by the thin dashed arrow. Next, during heating, warm air is blown out from the air blowing passage 16.
At this time, if you set the horizontal blade 23 so that it stands vertically,
Most of the hot air is blown out vertically downward through the opening 22 as shown by the thick solid arrow, and a portion is blown out horizontally as shown by the thin solid arrow.

According to this embodiment, the decorative panel is divided into the upper decorative panel 20 and the lower decorative panel 21, and the space between the upper and lower panels is used as part of the air outlet passage, and the lower decorative panel 21 has an opening 2.
2 and a horizontal blade 23 at one end of the opening 22, it is possible to easily and ideally separate cold and hot air as described above, which is cost effective. This is highly advantageous and has the effect of improving the comfort of the air-conditioned space.

Furthermore, since the spacing between the upper and lower panels can be easily reduced without sacrificing comfort, it is possible to create a design that has a sense of unity with the ceiling.

It goes without saying that by appropriately selecting the dimensions of the opening, the dimensions of the lateral blades, and the rotation angle of the lateral blades, it is possible to adjust the ratio of blowing in the horizontal direction and in the vertically downward direction.

In this embodiment, the unit main body 12 has a rectangular parallelepiped shape, the heat exchangers 14 are symmetrically located on both sides, and air is blown from both sides. Although a case has been described in which the blades have elongated holes and the horizontal blades 23 have a horizontally long blade shape, the present invention is not limited to this.

For example, the heat exchanger may be located on all sides, and the shape of the unit body may be cubic or cylindrical, and the design of the decorative panel may be changed accordingly.

If there are heat exchangers on all sides, air blowing passages can also be provided on all sides, and if the unit body is cylindrical,
The decorative panel also has a circular shape, and air blowing passages can also be formed around it.

Furthermore, even if the unit main body has a rectangular parallelepiped shape as in the above-mentioned embodiment, the hole opened in the bottom decorative panel is not long;
Even if a plurality of holes with appropriate dimensions are opened side by side, the same effect as described above can be expected.
