Abstract
In an air passage opening/closing device for a vehicle air conditioner, a driving member is disposed to apply driving force for a reciprocating movement of a film member to at least one position of the film member, and a guide member is provided in an air-conditioning case to guide the reciprocating movement of the film member. The film member has a flexible performance to move in a bend path, and has a rigidity to be moved along the guide member when pushing force from the driving member is applied to the film member. Thus, the air passage opening/closing device using the film member has a simple structure without a film-winding mechanism.
Claims34
An air passage opening/closing device comprising:
- an air duct for defining an air passage through which air flows;
- a film member having a predetermined flexible performance, the film member being disposed to reciprocate in the air passage for opening and closing the air passage;
- a heat exchanger, disposed in the air duct, for performing a heat exchange with air in the air passage;
- a driving member which applies driving force for a reciprocating movement of the film member to at least one position of the film member;
- and
- a guide member which guides the film member for the reciprocating movement of the film member,
- wherein the film member has a rigidity equal to or larger than a predetermined degree, so that the film member moves along the guide member when a pushing force pushing the film member is applied to the film member from the driving member;
- the air duct has a receiving space into which a part of the film member, including one end of the film member in a reciprocating direction of the film member, is received;
- and
- the receiving space is provided between the air duct and a side wall of the heat exchanger, the side wall being a part of a peripheral wall portion of the heat exchanger defining an air passage within the heat exchanger.
