BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner outlet which is attached to the end of a blower duct, and more specifically to a blower from a ceiling surface and a wall surface sandwiching a corner selectively or simultaneously. .

[0002]

2. Description of the Related Art In recent years, the number of cases of using a blow-out is increasing. This blow-out gives the space richness as an architectural environment, and it is expected that the number of applications will continue to increase. By the way, even if it is a useful blow-out as an architectural environment, its air conditioning design is not easy from the viewpoint of the air conditioning environment. That is, the warmed conditioned air rises during heating, and a state similar to bottom cooling is likely to occur in the lower part of the blowout.

As a means for solving such a problem, there is a conventional air outlet provided with a nozzle-shaped air outlet. FIG. 4 is a side view of the blowout to which the blowout nozzle is attached. A blowout nozzle 3 is provided on the ceiling 1 of the blowout space.
Is designed to blow conditioned air downwards at high speed. On the other hand, a wall surface outlet 5 is provided on the wall surface facing the blowout, and the wall surface outlet 5 can achieve heating of the lower portion of the blowout opening by blowing out obliquely downward from the wall surface. In this way, the blowing nozzle 3 and the wall surface outlet 5
In the conventional air outlet that also uses, the blowout nozzle 3 secures the reaching distance of the warm air 7 that reaches the lower portion of the blowout, and the warm air 9 from the wall surface outlet 5 to the blowout lower portion prevents the occurrence of bottom cooling. It had been done.

[0004]

However, if air is sent to the blow-out nozzle 3 provided on the ceiling 1 of the blow-out space at a predetermined speed in order to ensure a warm air reaching distance, a draft during cooling will be generated. There was a risk of this happening. Further, when the upper part of the blow-out space is a top light or a glass roof, there is a problem in mounting the blow-out nozzle itself. Further, at the wall surface outlet 5 provided on the wall surface, since the air can be blown out only in a diagonally downward direction from the wall surface, it is not possible to sufficiently blow out to the lower part of the blow-out (cannot be blown out in the direct downward direction), and the heating efficiency can be improved. could not. If the wall outlet 5 is provided on the ceiling side of the first floor in order to allow the air to be blown directly below, the cold air can only be blown out in the direct downward direction, which causes a draft to be hit directly by the cold air. It was The present invention has been made in view of the above circumstances, provides a corner outlet that does not generate a draft due to cold air, while being able to sufficiently blow out to the lower portion of the blowout without using a blowing nozzle. The purpose of this is to prevent harmful effects caused by the use of the blowout nozzle and to achieve efficient air conditioning in blowout.

[0005]

Means for Solving the Problems To achieve the above object, a corner outlet according to the present invention is a corner outlet for blowing out conditioned air to a blower through which a plurality of floors are vertically communicated with each other. A chamber box connected to the ceiling is installed on the ceiling surface of the lower floor in the blow-out and the corner between the lower and upper floors, and the lower surface outlet connected to the ceiling outlet is on the ceiling surface. Open on the lower surface of the facing chamber box, open the side surface outlet connected to the wall surface outlet to the side surface of the chamber box facing the wall surface, and connect one side of the plate-shaped damper to the lower surface outlet inside the chamber box and the wall surface. It is characterized in that the lower surface outlet and the side surface outlet can be selectively closed by swingably supporting between the air outlet and the air outlet.

[0006]

[Function] During heating, the damper is swung to the wall surface side to close the wall surface outlet, and the lower surface outlet is in an open state so that the air from the air ducts passes through the chamber box and from the ceiling air outlet. Blown out. Since the ceiling outlet opens on the ceiling surface, the blowing direction can be almost directly below,
Warm air efficiently reaches the lower part of the air blow. On the other hand, during cooling, the damper oscillates toward the ceiling surface, the lower surface outlet is blocked, the wall outlet becomes open, and the air from the air duct passes through the chamber box and blows out from the wall outlet. To be done. This eliminates the draft caused by the cold air being blown directly downward, and causes natural convection due to the descent of the cold air itself. Also, when the damper is arranged at a predetermined swing angle, conditioned air is simultaneously blown out from the ceiling outlet and the wall outlet at an appropriate ratio, and the air supply to the blower is not reduced, and the conditioned air is emitted from each outlet. It is possible to keep the wind speed at low.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a corner outlet according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a detailed sectional view of the corner outlet of the present invention, and FIG. 2 is an external view of the corner outlet of the present invention. Ceiling surface 1 on the lower floor in the open-air space
1, and a rectangular chamber box 17 is attached to a corner portion (corner) 15 sandwiched between the wall surface 13 between the lower floor and the upper floor, and the chamber box 17 is in a state in which the longitudinal direction is along the corner portion. It is located in. Chamber box 1
The end of the air duct 19 is connected to the air duct 7.
9 is a duct structure for normal wind speed (not for high speed duct). A lower surface outlet 21 is opened on a surface of the chamber box 17 facing the ceiling surface 11, and the lower surface outlet 21 is opened on the ceiling surface 11 by a ceiling outlet 23 (see FIG. 2).
See). A side surface outlet 25 is opened on the surface of the chamber box 17 facing the wall surface 13, and the side surface outlet 25 is opened on the wall surface 13 by the wall surface outlet 2.
7 (see FIG. 2). By forming the ceiling outlet 23 and the wall outlet 27 on the L-shaped decorative plate 29 that covers the corner 15, the workability can be improved and the appearance can be improved.

A rectangular plate-shaped damper 31 is provided inside the chamber box 17, and one side of the damper 31 is swingably supported by a corner of the chamber box 17 facing the corner 15 via a rotary shaft 33. ing. Also,
A support shaft 35 is fixed to the other side of the damper 31 on one side, and the support shaft 35 is slidably supported by an arc-shaped rail 37 formed on a side plate of the chamber box 17. Therefore, the damper 31 closes the lower surface outlet 21 when being swung toward the ceiling surface 11 side around the rotating shaft 33, and closes the wall surface outlet 27 when being swung toward the wall surface 13 side. . In other words, the damper 31 can selectively or simultaneously switch the blowout from the ceiling outlet 23 or the wall outlet 27.

The damper 31 can be rotated by rotating the rotating shaft 33 by a damper switching motor (not shown). In this case, if the damper switching motor is controlled by a well-known technique in accordance with the air conditioning operation mode, the damper 31 can be automatically switched so as to follow the cooling and heating operations. Further, when the damper 31 is rocked by the damper switching motor, the rocking angle of the damper 31 is detected by a limit switch or the like, and the rocking angle can be arbitrarily set and controlled based on the detected value. It is also possible to freely adjust the ratio of the amount of air blown out from the outlet 21 or the side air outlet 25.
The corner outlet 39 according to the present embodiment is configured with the chamber box 17, the lower surface outlet 21, the side surface outlet 25, and the damper 31 as main constituent members.

The corner outlet 39 configured as described above
The operation of will be described. FIG. 3 is a side view of the blowout for explaining the blowout condition. During heating, when blowing out to the lower part of the blowout opening, the damper 31 is swung to the wall surface 13 side around the rotation shaft 33, and the wall surface outlet 27 is closed. This allows
The lower surface outlet 21 is in an open state, and the air blown from the blower duct 19 passes through the chamber box 17 and is blown out from the ceiling outlet 23. The ceiling outlet 23 is the ceiling surface 11.
Since it is opened to the bottom, the blowing direction can be made almost directly below, and the warm air 41 can efficiently reach the lower part of the blowout. Further, if the corner outlets 39 are provided in all the corners 15 facing the blowout, a gentle airflow can be generated in the blowdown downward direction, and the bottom cold state caused by rising warmed conditioned air is effective. Will be prevented.

On the other hand, during cooling, the damper 31 is swung toward the ceiling surface 11 side, and the lower surface outlet 21 is closed. As a result, the wall surface outlet 27 is opened, and the blower duct 1
The air sent from 9 passes through the inside of the chamber box 17 and is blown out from the wall surface outlet 27. For this reason, the draft due to the blowout of the cool air in the immediately downward direction is eliminated, and natural convection occurs due to the descent of the cool air 43 itself. Further, in the intermediate period, by arranging the damper 31 at an appropriate swing angle, conditioned air is simultaneously blown out from the ceiling outlet 23 and the wall outlet 27 at an appropriate ratio, and the number of outlets increases. It is possible to suppress the wind speed at the blowout port to a low level, and it is possible to make it gentle without reducing the air supply to the blowout.

In the above-described embodiment, the chamber box 17 is provided with the damper 31 to switch the blowout from the lower surface outlet 21 and the side surface outlet 25. However, in order to switch the outlets, the lower surface outlet 21 and Sliding dampers and the like may be provided on the side air outlets 25, and the opening and closing of these may be controlled.
With such a configuration, as described above, it is possible to selectively or simultaneously blow out air from the lower surface outlet 21 and the side surface outlet 25, and it is also possible to simultaneously close them. Further, the corner outlet 39 according to the present invention is
Although it has been described as being used in the blow-out, it can also be used in a one-floor room in which a portion corresponding to the corner 15 is formed by providing the lower wall, and at that time, the same effect as described above can be obtained. Play.

[0013]

As described in detail above, according to the corner outlet according to the present invention, since the damper is swingably provided in the chamber box having the lower surface outlet and the side surface outlet, the heating is performed. At times, the damper can be swung to the wall surface side to blow out the air from the air duct from the ceiling air outlet so that the warm air can efficiently reach the lower part of the air blow. Further, during cooling, the damper can be swung to the ceiling surface side to blow out the air from the air duct from the wall surface outlet to eliminate the draft of the cool air. As a result, it is possible to efficiently perform air conditioning in blowout without using a blowout nozzle.
