Description

  The present invention relates to an air conditioning area adjustment device that adjusts an area in which a vehicle interior is air-conditioned by air conditioning air from an air conditioner.

  Conventionally, various proposals have been made on air conditioners that air-condition the entire vehicle interior. As this type of air conditioner, for example, outside air or inside air is passed through a heat exchanger provided in an air passage in an instrument panel by a blower, and air-conditioned air heat-exchanged by this heat exchanger is blown into an air-conditioning air. It is blowing out from the exit into the passenger compartment.

  By the way, in recent years, in order to reduce the air conditioning load of the air conditioner and realize energy saving, it is desirable to circulate the conditioned air blown into the passenger compartment in the front seat (driver's seat and front passenger seat) as much as possible. ing. For this reason, a technique is known in which air-conditioned air blown into the room is circulated on the front seat side by being sucked into an air-conditioning air suction port provided near the feet of the front seat (for example, see Patent Document 1). Thereby, only the periphery of the front seat side can be intensively air-conditioned, and comfortable zone air-conditioning can be realized.
