Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind direction conversion air supply device provided on an outer wall of a building or the like for supplying outdoor air into a room.

[0002]

2. Description of the Related Art Conventionally, in order to improve ventilation in a building, a method has been adopted in which an outer wall or the like is opened and an air supply device is provided in this opening. For example, as described in Japanese Utility Model Laid-Open No. 63-82137, a louver having a plurality of blades inclined at an angle is provided on the indoor side of the air supply device, and the inhaled air is supplied indoors. It is designed to blow out in a certain direction. Further, there is a louver whose angle can be changed manually.

[0003]

However, as described in Japanese Utility Model Laid-Open No. 63-82137,
In the air supply device provided with the louver, the air moves only in a certain direction in the room, and a local temperature change of the air in the room occurs. As a result, the temperature of the room may be locally reduced by the outside air, which may cause discomfort or a physiological disorder for a person in the room.
In addition, there is a problem that fresh outside air does not reach every corner of the room and ventilation efficiency of dirty air is poor.

The present invention has been made by paying attention to the above-mentioned problems, and an object thereof is to eliminate these problems and supply air from the outdoors to every corner of the room. Evenly distributed, good ventilation efficiency of dirty air,
Further, the present invention provides an airflow direction changing air supply device capable of preventing discomfort of the body and occurrence of physiological disorder.

[0005]

In the wind direction changing air supply device of the present invention, there is provided a wind direction changing air supply device which is attached to an opening of an outer wall or the like and is provided for supplying outdoor air into a room. A louver having a plurality of fixed blades radially expanded toward the indoor side at the indoor end of the tubular body of the air supply device, and an eccentric rotary drive adjacent to the outdoor side of the louver. And a turntable having the above-mentioned opening.

The above-mentioned rotary disk having an eccentric opening which is rotationally driven means a fan-shaped disk which does not entirely cover a circular shape.

[0007]

In the wind direction changing air supply device of the present invention, the louver is provided at the indoor side end of the cylindrical main body of the air supply device, and the louver is composed of a plurality of fixed blades radially expanded toward the indoor side. Since the rotary disk having an eccentric opening that is rotationally driven is provided adjacent to the outdoor side of, the supplied air is changed in direction by the rotation of the rotary disk and is diffused by the louver. The air supply from the outside is evenly distributed to every corner of the room, the ventilation efficiency of dirty air is good, and the discomfort of the body and the physiological disorder can be prevented.

That is, when the turntable rotates at a constant speed, the eccentric opening portion of the turntable continuously changes the direction to introduce the air supply into the room, and as a result, the air is directed in all directions in the room. The temperature difference with the outside air in the room is reduced,
The effects as described above can be obtained.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing an example of a wind direction conversion air supply device of the present invention, and FIG. 2 is a front view of a half portion of FIG. This wind direction conversion air supply device is attached to an opening such as an outer wall, and is used for supplying outdoor air into a room.

As shown in FIG. 1 or 2, a plurality of fixed blades 12 radially expanded toward the indoor side are provided at the indoor end 11a of the cylindrical main body 11 of the air supply device 10.
A louver 12 composed of a, 12a, ... Is provided.

On the outdoor side of the louver 12, adjacent to the louver 12, an eccentric opening 1 that is rotationally driven.
A turntable 13 having 3a (hatched portion shown in FIG. 2) is provided. The turntable 13 is rotationally driven at a constant speed by a motor 14 mounted on the turntable 13.

As a means for rotating the turntable 13 at a constant speed, a so-called AC-DC converter 15 for converting AC electricity into DC is provided on the rear side of the outside of the motor 14.
Are provided in the casing 16 together with the motor 14.

The casing 16 is held on the cylindrical main body 11 by a plurality of support rods 17 so that the rotary disc 13 on the tip end side can be smoothly driven. Further, the motor 14 is supplied from a power cord 18 connected to an AC-DC converter 15, converted into direct current, and then driven.

The air supply device 10 installed on this wall surface or the like is
It is turned on and off by a switch 19 provided on the indoor side so that the user can freely turn on and off. Therefore, it is possible to stop the rotary disk 13 as necessary and introduce the outside air in the same direction inside the room.

FIG. 3 is a front view of the turntable 13 described above, and the opening position is continuously and sequentially moved by being rotated at a constant speed by the motor 14 as shown by the arrow in the figure. , The air supply guided by the louver 12 is
It will be introduced into the room while changing its direction.

That is, the outside air having a low temperature guided by the louver 12 is sufficiently mixed with the warm air in the room until the turntable 13 is rotated to the same position next time, and the temperature of the air in the room is increased. It has the effect of reducing the difference. The air flow is not concentrated in one place due to the opening 13a of the turntable 13 which is rotated at a relatively low speed. It is designed so that things that do not impair the experience do not occur.

[0017]

In the wind direction changing air supply device of the present invention,
At the indoor end of the tubular body of the air supply device, a louver composed of a plurality of fixed blades radially expanded toward the indoor side, and an eccentric rotatably driven adjacent to the outdoor side of the louver. Since the rotating disk having the opening is provided, the direction of the supplied air is changed by the rotation of the rotating disk and is diffused by the louver so that the air supply from the outside is evenly distributed to every corner of the room. Ventilation efficiency of well-circulated and dirty air is good, and it is possible to prevent physical discomfort and physiological damage.

That is, when the turntable rotates at a constant speed, the direction is continuously changed through the opening of the eccentric turntable to introduce the air supply into the room, and as a result, the air is directed in all directions in the room. The temperature difference with the outdoor air in the room is reduced, and the above-mentioned effects are obtained. Therefore, it is suitable as a wind direction conversion air supply device.
