Patent ID: 7540321

Claim:
An air conditioner for a vehicle comprising: a housing for defining an air passage through which air flows, the air passage having a main passage and first and second separate passages branched from the main passage; an evaporator, disposed in the main passage of the housing, for cooling air; a heat exchanger for heating air, the heat exchanger being disposed in the main passage at a downstream air side of the evaporator in a part area of the main passage; a control member which is provided to adjust an air flow from the evaporator into the first separate passage and an air flow from the heating heat exchanger into the first separate passage; a limiting wall member extending from an upper end of the evaporator to a lower end of the heat exchanger approximately in an arc shape at a distance from the heat exchanger on a downstream air side of the heat exchanger, wherein: the limiting wall member is separated from the lower end of the heat exchanger to have a rear opening between the lower end of the heat exchanger and the limiting wall member, through which air from the heat exchanger flows into the second separate passage leading to a rear area; the limiting wall member is provided to partition the first separate passage from the main passage; the control member is arranged in the limiting wall member; a partition plate for partitioning the main passage into a cold air passage through which air from the evaporator flows to the first separate passage, and a warm air passage through which air from the heat exchanger flows; the control member is a flexible sheet member at least partly defining a through hole; the limiting wall member has a guide member for guiding the sheet member; the partition plate extends from an end portion of the heat exchanger to a position immediately before the limiting wall member; and the sheet member is displaceable along the limiting wall member in the guide member relative to the partition plate.
