Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a ceiling-embedded air conditioner having an improved outlet for conditioned air in a decorative panel.

[Conventional technology]

A conventional ceiling-embedded air conditioner, as shown in FIG.
Main body 1 of an air conditioner provided with a heat exchanger, a blower, etc.
And a chamber block 2 mounted below the main body 1 in which an air intake passage and an air outlet passage are defined.
And a rectangular or square decorative panel 3 that covers the lower surface of the ceiling 4.
It is composed by.

FIG. 6 is a perspective view of the decorative panel 3 as seen from below, and 5 is a square indoor air inlet provided in the central portion of the decorative panel 3, the opening surface of which is a lattice-shaped coffin 6a. Are formed. Reference numeral 7 is a conditioned air outlet formed in four outer directions around the suction port 5, as shown in FIG.
Alternatively, the horizontal louver 8 for adjusting the wind direction as shown in (B)
And the vertical louvers 9 are attached at the same position in all the outlets 7.

In this air conditioner, the indoor air sucked from the suction port 5 is cooled or heated by the main body 1 via the chamber block 2 to become conditioned air, which is blown through the chamber block 2 from the air outlet 7 to four directions inside the room. It is like this.

[Problems to be solved by the device]

The air conditioner is designed to adjust the wind direction by means of a horizontal louver 8 and a vertical louver 9 attached to the blowout port 7 of the decorative panel 3, but the blowing wind direction into the room is generally downstream of the flow, that is, downward. Strongly dominated by louvers mounted on.

Therefore, in blowing out conditioned air to every corner of the room,
When the indoor planar shape is almost square as shown by the broken line 10b in FIG. 7, the conventional horizontal louvers 8 and the vertical louvers 9 are attached to the same positions at all the outlets 7 in the decorative panel 3. On the other hand, in the case where the room has a rectangular planar shape, there is a problem in that a region where the conditioned air is not sufficiently distributed (hatched portion of solid line 10a in FIG. 7) occurs.

Furthermore, since the arrangement direction of the louvers attached below the air outlet 7 is different, the arrangement of the lighting fixtures on the ceiling surface, that is, the linear arrangement direction seen in a general office and the arrangement of those with louvers. There was a drawback that the directions did not match and the interior was lacking in harmony and gave a strange feeling.

In view of the above circumstances, the present invention allows a decorative panel having air outlets in four directions to allow conditioned air to reach every corner of a room corresponding to the planar shape of the room, and a lighting device on the ceiling surface. It is intended to provide a ceiling-embedded air conditioner capable of achieving harmony with the above.

[Means for Solving the Problems]

The present invention relates to a ceiling-embedded air conditioner that covers a lower surface of a ceiling, has a suction port for indoor air, and has four outlets for blowing conditioned air in four directions around the suction port. A vertical louver for adjusting the wind direction is attached to each of the two facing air outlets upward and a horizontal louver is attached to the lower side, and a horizontal louver is moved upward and vertically to each of the other two outlets facing each other. The louver was installed below.

[Action]

In the present invention, of the four outlets formed on the decorative panel, a vertical louver is attached to the upper side and a horizontal louver is attached to the lower side of the two outlets facing each other, and two outlets facing the other are provided. By attaching a horizontal louver to the upper side and a vertical louver to the lower side of the air outlet, the louvers arranged on the lower surfaces of all the air outlets have the same mounting direction.

Further, since the air blowing direction is mainly governed by the louver mounted below the decorative panel, a large amount of air flows in two directions from one of the two facing air outlets and the other two facing air outlets. A small amount of air is blown out from the blowout port in the other two directions.

〔Example〕

A first embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, the decorative panel 3 has a square shape, and a square room air outlet 5 is provided in the center thereof.
A large number of parallel ledges 6 parallel to the two sides of one of the air outlets 5 facing each other are formed on the opening surface.

Four rectangular air-conditioning air outlets 7a, 7b, which are parallel to the respective sides of the suction port 5, are provided in four directions outside the suction port 5.
7c and 7d are formed. The two outlets 7a, 7c located at positions facing each other with respect to the suction port 5 respectively have a second
As shown in FIG. (A), a lateral louver 8 which is rotatable downward about a shaft 8a and parallel to the long sides of the outlets 7a and 7c, and a lateral louver 8 above which is rotatable about a shaft 9a. A large number of vertical louvers 9 orthogonal to the louver 8 are attached. Further, as shown in FIG. 2 (B), the two air outlets 7b, 7d at the other opposite positions are provided with a vertical louver 9 downward as opposed to the air outlets 7a, 7c described above. The horizontal louvers 8 are attached above.

The structure and operation of the air conditioner are the same as those of the conventional example shown in FIG. 5, and the description thereof will be omitted.

In this embodiment, the installation direction of the louver arranged on the lower surface of the decorative panel 3 at all the outlets 7a, 7b, 7c, 7d is the first.
It becomes the same as shown in the figure. Further, since the lower louver is dominant in the main blowing direction of the conditioned air, the blowing amount of the conditioned air from the outlet is equal to that of the outlet in which the lateral louver 8 is downward.
A large amount is provided in two directions blown from 7a and 7c, and a small amount is provided in the other two directions in which vertical louvers 9 are blown out from blower outlets 7b and 7d located below. Since the blowing amount is proportional to the reaching distance of the blowing air, as shown in FIG. 3, when the air conditioner is installed on the ceiling of the rectangular room 10a, the conditioned air spreads to every corner of the room. The entire room is uniformly and well conditioned. The arrows in FIG. 3 represent the reach of conditioned air.

Furthermore, all outlets 7 observed from the lower part of the room
Since the louver array of a, 7b, 7c, 7d is unified in the same direction, as shown in FIG. 3, if the direction of arrangement of the lighting fixtures 11 etc. on the ceiling surface is matched, the interior surface will be harmonized. To be

FIG. 4 is a perspective view of a decorative panel according to a second embodiment of the present invention, in which all the outlets 7a, 7b,
A linear decoration 12 is provided to emphasize the directionality in conformity with the arrangement direction of the lower louvers in 7c and 7d. The other structure is the same as that of the first embodiment shown in FIGS. 1 to 3.

Therefore, in the same manner as the first embodiment, the entire room is uniformly and well conditioned, and in addition to the arrangement of the louvers, the linear decoration 12 that emphasizes the directionality further improves the harmony of the interior surface.

[Effect of device]

According to the present invention, a vertical louver is attached upward and a horizontal louver is attached downward at each of two air outlets facing each other with respect to a suction port of a decorative panel covering the lower surface of the ceiling, and the other two air outlets facing each other are provided. By installing the horizontal louver upward and the vertical louver downward at each of the outlets, the amount of air blown out from the two outlets facing each other and the amount of the other two outlets facing the other. The amount of air blown out can be changed,
In the rectangular guide, the conditioned air spreads to every corner of the room and the entire room is uniformly and well conditioned.

Further, since the louver arrangements of all the air outlets are unified in the same direction, it is possible to achieve harmony with the arrangement of lighting equipment and the like.
