Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a vehicle air conditioner,
In particular, the present invention relates to a vehicle air conditioner that can be controlled independently on the driver's seat side and the passenger's seat side and further has a ventilator outlet in the rear seat.

[0002]

2. Description of the Related Art An air conditioner for a vehicle having independent ventilator outlets at the rear seats has independent air conditioning ducts for a driver seat and a passenger seat. Then, based on the outlet temperature and the air conditioning mode set by the occupants on the driver's seat side and the passenger's seat side, the ventilator outlets and the foot outlets respectively provided on the driver's seat side or the passenger's seat side, respectively. Independently controlled air can be blown out.

[0003] Some of the above-described vehicle air conditioners of the left-right independent control type further have a ventilator outlet (rear VENT outlet) for a rear passenger at the rear of the center console. In this vehicle air conditioner, a rear VENT outlet communicates with a front driver's seat side VENT outlet, and a door (rear VE) is provided near the rear VENT outlet.
The rear VENT door opens and closes in conjunction with an air conditioning mode set on the driver's seat side.
That is, a mode in which relatively cool air is blown from the ventilator outlet on the driver's side (driver's side VENT outlet), such as the VENT mode or the bi-level (B / L) mode for the driver's seat air conditioning mode, is set. The rear VENT door opens in conjunction with this, and the air conditioned by the air conditioning duct for the driver's seat side is filled with the VENT outlet on the driver's seat side and the rear VENT.
