Document Type and Number:
WIPO Patent Application WO/2017/149855
Kind Code:
A1
Abstract:
The present invention provides an inside/outside air switching unit capable of minimizing the transmission of outside noise to the inside of a vehicle in an inside and outside air introduction mode in which both outside air and inside air are introduced. An inside/outside air switching unit (2) is equipped with: an opening-closing member (22) that is housed within an inside/outside air case (20), and opens and closes an outside air introduction port (201) and an inside air introduction port (202); and drive devices (30, 10a) that drive the opening-closing member (22). The opening-closing member (22) has: a first opening-closing door (23) that is driven by the drive devices (30, 10a) to a position to open the outside air introduction port (201) in the inside and outside air introduction mode; and a second opening-closing door (24) that is driven by the drive devices (30, 10a) to a position to open the inside air introduction port (202) in the inside and outside air introduction mode. The drive devices (30, 10a) are configured so as to drive the first opening-closing door (23) to a position to interrupt an inside/outside communication path (20a) between the outside air introduction port (201) and the inside air introduction port (202) within the inside/outside air case (20), in the inside and outside air introduction mode.
