Abstract:
An air conditioner in combination with a vehicle comprising:a case for forming an air passage through which air flows, the case including a first air opening through which air is blown toward a center upper side of a passenger compartment and a second air opening through which air flows toward a windshield of the vehicle, the air passage including an air port through which air is introduced into the second air opening; a heating heat exchanger disposed at a vehicle front side in the case in a substantially horizontal direction for heating air upwardly passing through the heating heat exchanger from below to form a bypass passage within the case at a vehicle rear side of the heating heat exchanger through which air bypasses the heating heat exchanger; a warm air guide disposed above the heating heat exchanger for guiding warm air heated by the heating heat exchanger into an air mixing space in which warm air passing through the heating heat exchanger is mixed with cool air passing through the bypass passage, the air mixing space being formed at a vehicle rear side of the heating heat exchanger next to the heating heat exchanger in the air passage; and a switching door for selectively opening the first air opening while closing the air port and closing the first air opening while opening the air port, wherein: the warm air guide has an end portion for defining the air port, and extends approximately horizontally; the air port is provided substantially horizontally; a direct passage from the air port to the second air opening extends obliquely toward a front upper side of the vehicle; the first air opening is substantially vertically disposed in a rear side wall of said case and is provided at a vehicle rear side position of the air mixing space; the air port is provided at an upper side position of the air mixing space; the second air opening is provided on an approximately upper side at an upper side position of the warm air guide; and the switching door has an end portion which contacts the end portion of the warm air guide and is positioned approximately horizontally when the switching door closes the air port.
