Figure 4 is an overall perspective view, Figures 5a to 5c
The previous drawings show the relationship between damper position and wind quality.
Figure 5a is a cross-sectional view showing a mixed flow supply state of outside air and vent air, Figure 5b is a cross-sectional view showing a state where only vent air is supplied, and Figure 5c is a cross-sectional view showing a state where both outside air and vent air are shut off. The sectional views and drawings from FIG. 6 to FIG. 8 show conventional examples, respectively.
The figure is an overall perspective view using two dampers, and FIGS. 7 and 8 are sectional views showing different conventional examples using one damper. 1... Ventilation duct, 2...

Claims

[Scope of utility model registration request]

A ventilation duct is formed with a three-pronged branch path, and is provided with an indoor air outlet, an internal air conduction port, and an outside air inlet. In an outside air introduction ventilation device consisting of one rotating damper and a movable link connected to the damper to control rotation of the damper, the one damper has a thin-walled driving damper and a driven damper having the rotation shaft. A damper mechanism for outside air introduction ventilation, characterized in that the damper mechanism is connected by a connecting hinge, and the movable link is connected to the active damper.
