DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a ventilation system for buildings,
More particularly, the present invention relates to a ventilation device for buildings that introduces external air into the interior.

[0002]

2. Description of the Related Art In general, a building such as a high-rise building is provided with a building ventilation device for introducing outside air into the building. As an example of this ventilation device, for example,
The following configuration is known. That is, a rectangular frame is provided corresponding to the window of the building, and an auxiliary window member is provided at a lower portion of the frame to form an upper window frame and a lower auxiliary frame. . Then, a window glass is attached to the window frame, and a ventilation auxiliary window as a ventilation device is attached to the auxiliary frame so as to be freely opened and closed. In such a ventilation device, by opening the auxiliary window, air from the outside of the building is introduced into the inside, and thus the inside of the building can be ventilated.

[0003]

In such a known ventilation device, an auxiliary ventilation window is provided below the window glass,
When it is released, it is turned inside the building around its lower end. Therefore, when the opening and closing operation of the auxiliary window is performed, a dedicated space for the opening and closing operation is required inside the auxiliary window, and there is a problem that the use efficiency of the floor of the building is deteriorated. Further, in the case of using such an auxiliary window, a design in appearance when the auxiliary window is released is not preferable, so that the auxiliary window is often covered with an exterior plate, and there is a problem that a ventilator becomes expensive. . Further, with the recent trend toward OA, there is an increasing number of buildings (generally referred to as "intelligent buildings") provided with many wirings, such as computers, under the floor. Since the location of the above-mentioned arrangement corresponds to the underfloor space, it is difficult to apply the above-described ventilation device using the auxiliary window.

[0004] It is an object of the present invention to provide a building ventilation system that does not require a dedicated space for opening and closing operations, and thus can increase the use efficiency of the floor surface.

Another object of the present invention is to provide a ventilation system for a building which can be conveniently used for an intelligent building and which can maintain a high appearance design without using an exterior plate. .

According to the ventilation device of the first aspect of the present invention,
Since the cylindrical housing is formed by combining the first and second members with each other, the cylindrical housing can be formed with a relatively simple configuration. When the rotating body is disposed in the internal space of the cylindrical housing, and the rotating body is positioned at the closed position, the first closing portion of the rotating body closes the outer opening of the cylindrical housing, and the second closing portion forms the cylindrical housing. Closes the inner opening, thereby stopping the introduction of outside air. On the other hand, when the rotating body is positioned at the open position, the first closing portion releases the outer opening of the cylindrical housing, and the second closing portion releases the inner opening of the cylindrical housing, so that the outside air is released from the outer opening of the cylindrical housing. And through the inner opening into the interior of the building. further,
Since the introduction and stop of the outside air are controlled by the rotating body which is rotated in the internal space of the cylindrical housing, the use efficiency of the floor of the building is not reduced, and the external shape of the cylindrical housing is a ventilation device. Therefore, a high design can be maintained even when air is introduced. Furthermore, by making the outer diameter of the cylindrical housing smaller than that of the pair of frame members, the cylindrical housing can be arranged to be housed between the pair of frame members.

According to the ventilating apparatus of the second aspect of the present invention, the movement preventing projection is provided in relation to at least one of the first and second closing portions of the rotating body, and the movement preventing projection and the rotating body are mutually connected. A seal member is provided on one or both of the contact surfaces. Therefore, when the rotating body is positioned at the closed position, the mutual contact surfaces of the movement preventing projection and the rotating body are in contact with each other via the seal member, and the introduction of outside air can be reliably prevented. In addition, since the seal member is provided on one or both of the mutual contact surfaces of the movement preventing protrusion and the rotating body, the seal member substantially acts on the inner peripheral surface of the cylindrical housing when the rotating body rotates. Therefore, the rotating body can be smoothly rotated and wear of the seal member can be prevented.
