Patent attributes
In a vehicle air conditioner, a foot door is rotatably supported for opening and closing a foot opening and an air port communicating with defrost and face openings. The foot door has a guide plate. The guide plate functions as a heated air guide portion for directing heated air heated by a heating device to merge with cooled air that bypasses the heating device when the foot door is at a defrost/face mode position. The guide plate functions as a cooled air guide portion for directing the cooled air to merge with the heated air when the foot door is at a foot mode position. Accordingly, the heated air and the cooled air are sufficiently mixed with each other. Because the guide plate is moved for switching the defrost/face mode position and the foot mode position, the flow of air is not blocked by the guide plate.
