Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable 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, by improving ventilation in a building, eliminating indoor air pollution (humidity, carbon dioxide, etc.), and keeping indoor humidity below a predetermined value, mites and mold are generated. As a method of preventing this, a method of opening an outer wall or the like and providing an air supply device in this opening is adopted. For example, Japanese Patent Application Laid-Open No. 59-41590 discloses a ventilation opening for opening and closing a damper with a shape memory alloy. In Japanese Utility Model Laid-Open No. 63-82137, there is provided a louver in which a plurality of blades having inclined angles are arranged, and the inhaled air is introduced toward a certain direction in the room. Is listed.

Further, as a method for preventing the adverse effects such as coldness due to the intake of outside air, there is provided an opening / closing mechanism which allows the user to arbitrarily adjust the angle of the louver, and an internal ventilation system in conjunction with the control of the entire ventilation system. An air supply device having a mechanism capable of opening and closing a damper is also known.

[0004]

However, in the ventilation port described in Japanese Patent Laid-Open No. 59-41590, the damper is opened and closed at a specific temperature as a boundary, and the damper according to the temperature is used. However, there is a problem that the opening cannot be continuously set.

Further, in the air supply device provided with the louver as described in Japanese Utility Model Laid-Open No. 63-82137, if the louver is fixed, cold outside air will flow only in a certain direction in the room. When introduced, the temperature of the air in the room changes locally, causing the human body to feel cold. As a result, there is a possibility that a person in the room may experience discomfort or may cause a physiological disorder.

Further, in the air supply device as described above,
There is also used a damper that can be operated manually so that it can be opened and closed as needed, but it is inadvertently left closed, resulting in insufficient ventilation and contamination of indoor air. Is left. In order to solve the above-mentioned problems, the intake amount of outside air is limited by adjusting dampers and louvers, so that the originally required ventilation amount is not secured and moisture is not completely removed. Condensation and even mite and mold were occurring.

Further, there is a problem of space in a round air supply device provided with an electric motor mechanism for adjusting the angle of a louver, and in an apartment house made of RC or the like, it cannot be attached to an outer wall surface. However, in the case of the rectangular type, the electric motor mechanism was housed integrally, but there was a problem that an extra space had to be provided outside the outer wall surface.

The present invention has been made by paying attention to the above-mentioned problems, and an object of the present invention is to solve these problems and to provide a necessary ventilation amount or an outside air to the room. (EN) Provided is a variable air supply device capable of automatically adjusting the flow direction according to the outside air temperature, preventing a cold feeling for a human body, and preventing a harmful effect caused by dew condensation in a room.
