Claim:
A two layer type air conditioner for vehicle comprising: a blower having an intake duct arrangement for inhaling the inside air and outside air, a double suction type scroll case mounted on the intake duct arrangement and divided into two passages by a partition plate, a blower fan rotatably mounted in the two passages, and a motor for rotating the blower fan; an air conditioning case housing an evaporator therein for cooling the air blown from the blower and a condensed water drain hole for draining condensed water generated from the evaporator, the air conditioning case being divided into two passages corresponding to the scroll case; a drain arrangement for draining water induced into the blower to a water outlet of the air conditioner, the drain arrangement including: (a) a drain pipe for communicating the lower end of the intake duct with the lower end of the air conditioning case; and (b) a drain passage having an inlet at the end of the drain pipe and an outlet below its inlet; the drain passage outlet being above the water outlet of the air conditioner and connected in gravity liquid flow relation to the water outlet, the drain passage directly communicating the drain pipe with the water outlet in a way so water flowing in the drain passage is isolated from passages of the air conditioning case in which the air flows so that water flowing in the drain passage is prevented from flowing into the air conditioning case, the drain passage outlet being located below, by a predetermined amount, the drain hole and a drainage space formed beneath the evaporator at the lower end of the air conditioning case.
