Airflow distributing device for automotive air-conditioning system

An air flow distributing device for use with an automotive air-conditioning system having air cooling means and air heating means, comprising:

• a first casing containing therein said air cooling means and said air heating means for cooling and heating the air passing therethrough;
• a second casing located at a downstream end of said first casing and having therein first, second and third cells which have respective inlet openings facing the chamber defined in said first casing, said inlet openings being arranged to lie on a common flat plane;
• first, second and third ducts which are respectively communicable with said first, second and third cells for providing respective communications between given portions of the passenger compartment and said cells;
• a flat plate member having a size to sufficiently cover said inlet openings of said first, second and third cells and lying on said common flat plane to cover said inlet openings, said plate member having an opening and being rotatable about an axis perpendicular to the face of said plate member so that the opening is open to at least one of said inlet openings when said plate member assumes a given angular position;
• means for selectively taking first and second positions to direct air to said ducts, said first position being a position in which communication with said first cell and said first duct is established and simultaneously communication between said first and third cell is blocked, said second position being a position in which communication between said first duct is blocked and simultaneously communication between said first and third cell is established;
• and
• control means for remotely controlling the rotational movement of said plate member.
