内の羽根に連結されている。BACKGROUND OF THE INVENTION Conventional damper devices of this type are disclosed in, for example, Japanese Patent Application Laid-open No. 1-127850 and Japanese Patent Application Laid-open No. 2-1999.
The configuration is as disclosed in Japanese Patent No. 115650. That is, disc-shaped blades are provided in a cylindrical sheet metal main body, and the blades are rotated by a motor or a rotary solenoid. The main body is connected to a duct that constitutes a ventilation system, and forms part of the ventilation system. When the blades are open, they are parallel to the airflow, and when closed, they are perpendicular to the airflow, closing the ventilation path of the main body. A drive device such as a motor or a rotary solenoid for moving the blades is attached to the outside of the main body via a mounting member, and its output shaft is connected to the blades inside the main body.

For example, if the ventilation system is configured as a conveyance path that sends cold air for cooling to each room, damper devices for rooms that require cooling are opened, and damper devices for rooms that do not require cooling are closed. This allows each room to be cooled as needed.

いる。DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a front view of a damper device showing an embodiment of the present invention, FIG. 2 is a side view thereof, and FIGS. 3 and 4 are schematic sectional views of essential parts, respectively. In the damper device of this embodiment, an elliptical blade 2 is supported by a shaft so as to be rotatable about its short axis in a cylindrical body 1 with open ends and an air passage having a circular cross section. . Both ends of the body 1 have a cylindrical body 3 made of sheet metal that can be connected to a duct as connection openings.
The body 4 is made of a heat-insulating resin such as vinyl chloride or styrene. The cylindrical body 3 is integrated with the body 4 by an insert when the body 4 is molded, and is integrated with the body 4 depending on the connection method (external fit or internal fit) with the duct, as shown in FIGS. 3 and 4. Further, a motor 6 is attached to the outer peripheral portion of the body 1 via a mounting leg 5, and its rotating shaft is connected to the shaft of a blade 2 pivotally supported within the body 1 so as to be capable of transmitting torque. The blade 2 is formed into an ellipse shape similar to the shape of the cut surface when the air passage of the body 1 is cut diagonally, and the shaft is fixed on the short axis of the blade 2.

Become. In this damper device, since the blade 2 is not circular but oval, the amount of rotation from fully open to fully closed is small, and by adjusting the amount of rotation, it is possible to finely adjust the amount of ventilation.
The shape of the blade 2 also improves the closing performance by itself. If a cooling ventilation system including a damper device is configured as described above, the ventilation system will be installed in the ceiling of the building, and cold air of approximately 10 degrees Celsius will flow during cooling. . At this time, the temperature in the attic is usually around 32 degrees Celsius in the summer, and it is humid, but the part made up of the duct is covered with heat insulating material, and the body 4 of the damper device has heat insulating properties, so the whole system The insulation will prevent condensation from leaking through the ceiling. That is, prevention of dew condensation in the damper device can be realized at low cost.
