[Industrial applications]

 The present invention relates to a corner outlet attached to an end of a ventilation duct, and more specifically, to a corner outlet that selectively or simultaneously blows air from a ceiling surface and a wall surface sandwiching a corner portion.

[0002]

[Prior art]

 In recent years, the number of cases of adopting 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 increase in the future. By the way, even if a blow-through is useful as an architectural environment, it is not easy to design the cooling and heating from the viewpoint of the air-conditioning environment. That is, the warmed conditioned air rises during heating, and a condition similar to bottom cooling tends to occur in the lower part of the blow-out.

As a solution to such a problem, there is a conventional blowout port provided with a nozzle-shaped blowout port. 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, and the blowout nozzle 3 can blow out conditioned air downward 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 is capable of achieving heating of the lower portion of the blowout opening by blowing out obliquely downward from the wall surface. As described above, in the conventional outlet that uses the outlet nozzle 3 and the wall surface outlet 5 together, the outlet nozzle 3 secures the reaching distance of the warm air 7 reaching the lower portion of the outlet, and the lower portion of the outlet from the wall outlet 5 is provided. Together with the warm air 9 to the bottom, the occurrence of a cold bottom condition was prevented.

[0004]

[Problems to be solved by the device]

 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 secure a warm air reach distance, a draft during cooling may occur. Also, if the upper part of the blow-out space is a top light or a glass roof, there was a problem with the attachment of the blow-out nozzle itself. In addition, the wall outlets 5 provided on the wall surface can only blow air obliquely downward from the wall surface, so it is not possible to sufficiently blow the air to the lower part of the blowout (it cannot blow directly down), thus improving heating efficiency. I couldn't. If the wall outlets 5 are installed on the ceiling side of the first floor to allow the air to blow out directly below, this time the cold air can only be blown out in the direct downward direction, creating a draft that is directly hit by the cold air. Became. The present invention has been made in view of the above circumstances, and provides a corner outlet that can sufficiently blow to the lower part of the blower without using a blowout nozzle and that does not generate draft due to cold air. Therefore, it is intended to prevent the harmful effects of using the blowout nozzle and achieve efficient air conditioning in the blowout.

[0005]

[Means for Solving the Problems]

 The configuration of the corner outlet according to the present invention to achieve the above object is a corner outlet that blows out conditioned air to the blowouts in which a plurality of floors communicate with each other at the upper and lower sides, and a chamber box that is connected to a ventilation duct. The lower surface of the chamber box facing the ceiling surface is provided in the ceiling between the lower floor and the upper floor between the lower and upper floors. A side outlet connected to the wall outlet is opened on the side of the chamber box facing the wall, and one side of the plate-shaped damper is placed between the bottom outlet and the wall outlet in the chamber box. It is characterized in that it is swingably supported and that the lower face outlet and the side face outlet can be selectively closed by swinging the damper.

[0006]

[Action]

 During heating, the damper is swung to the wall side, the wall outlet is blocked, the bottom outlet is open, and the air from the air duct passes through the chamber box and is blown out from the ceiling outlet. It Since the ceiling outlet is open to the ceiling surface, the outlet direction can be almost directly below, and the warm air efficiently reaches the blowout lower part. On the other hand, during cooling, the damper oscillates toward the ceiling side, the lower surface outlet is blocked, the wall surface outlet becomes open, and the air from the air duct passes through the chamber box and the wall surface outlet. Blown out from. This eliminates the draft caused by the cold air being blown directly downward, and produces 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, without reducing the air supply to the blowouts. It is possible to keep the wind speed from the exit low.

【Example】

 Hereinafter, a preferred embodiment of a corner outlet according to the present invention will be described in detail 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. A rectangular chamber box 17 is attached to the ceiling surface 11 of the lower floor and the corner portion 15 between the lower floor and the upper floor in the void space, and the chamber box 17 is long. The directions are arranged along the corners. The end of the air duct 19 is connected to the chamber box 17, and the air duct 19 has a duct structure for normal wind speed (not for high speed duct). A lower surface outlet 21 is opened on the surface of the chamber box 17 facing the ceiling surface 11, and the lower surface outlet 21 is connected to a ceiling outlet 23 (see FIG. 2) opening on the ceiling surface 11. 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 connected to a wall surface outlet 27 (see FIG. 2) opening on the wall surface 13. By forming the ceiling outlet 23 and the wall outlet 27 on the L-shaped decorative plate 29 that covers the corners 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 rotation shaft 33. Has been done. 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 it is swung toward the ceiling surface 11 side around the rotating shaft 33, and closes the wall surface outlet 27 when it is swung toward the wall surface 13 side. ing. That is, 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 swung by the damper switching motor, the swing angle of the damper 31 can be detected by a limit switch and the swing angle can be arbitrarily set and controlled based on the detected value. It is also possible to freely adjust the proportion of the amount of air blown from the lower surface outlet 21 or the side surface 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 operation of the corner outlet 39 thus configured will be described. FIG. 3 is a side view of the blowout for explaining the blowout condition. When the air is blown out to the lower part of the blow-out during heating, the damper 31 is swung to the wall surface 13 side around the rotation shaft 33, and the wall surface outlet 27 is closed. As a result, the lower surface outlet 21 is opened, and the air supplied from the air duct 19 passes through the chamber box 17 and is blown out from the ceiling outlet 23. Since the ceiling outlet port 23 opens on the ceiling surface 11, the outlet direction can be made almost directly below, and the warm air 41 can efficiently reach the lower portion of the blowout port. 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 air supplied from the air duct 19 passes through the chamber box 17 and is blown out from the wall surface outlet 27. For this reason, the draft caused by the cold air being blown directly downward is eliminated, and natural convection occurs due to the descent of the cold 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 outlets increase, respectively. It is possible to keep the wind speed at the blowout port low and 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. The outlet 21 and the side air outlet 25 may be provided with slide dampers and the like, and the opening and closing of these may be controlled. With such a configuration, similarly to the above, it is possible to selectively or simultaneously blow out from the lower surface outlet 21 and the side surface outlet 25, and it is also possible to simultaneously close them. Further, although the corner outlet 39 according to the present invention has been described as being used in the blow-out, it can also be used in a one-floor room where a portion corresponding to the corner 15 is formed by providing the lower wall. In that case, the same effect as described above can be obtained.

[0013]

[Effect of device]

 As described in detail above, according to the corner outlet of the present invention, the damper is swingably provided in the chamber box having the lower surface outlet and the side surface outlet, so that the damper is attached to the wall surface side during heating. The air blown from the blower duct can be blown out from the ceiling outlet by oscillating to make the warm air efficiently reach the lower part of the blowout. Further, during cooling, the damper can be swung to the ceiling surface side, and the air blown from the air blow duct can be blown out from the wall 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.
