In a vehicle air conditioner, an evaporator is disposed at an upper side of a blower approximately horizontally so that air blown by the blower passes through the evaporator from below upwardly. The evaporator is slightly tilted from a horizontal surface by a predetermined angle, and the blower is disposed in such a manner that air is mainly blown by the blower toward the evaporator in a direction substantially parallel to a tangential line at a scroll finish portion of the scroll casing. Accordingly, condensed water on a bottom heat-exchanging surface of the evaporator can be pushed downwardly by component force of the flow of air mainly blown from the blower.

1. Field of the Invention
The present invention relates to a vehicle air conditioner, which effectively improves draining performance of condensed water in a cooling heat exchanger while reducing a size of an interior unit disposed in a passenger compartment.
2. Description of Related Art
Additional objects and advantages of the present invention will be more readily apparent from the following detailed description of preferred embodiments when taken together with the accompanying drawings, in which:
FIG. 1 is a side view of an interior unit of a vehicle air conditioner, provided in a passenger compartment, according to a first preferred embodiment of the present invention;
FIG. 2 is a front view of the interior unit in FIG. 1, when being viewed from an inner side of the passenger compartment;
Preferred embodiments of the present invention will be described hereinafter with reference to the accompanying drawings.
A first preferred embodiment of the present invention will be now described with reference to FIGS. 1-5. FIGS. 1 and 2 show a mounting state of an interior unit 10 of a vehicle air conditioner, on a vehicle. The arrangement of the interior unit 10 on the vehicle corresponds to the arrangement in FIGS. 1 and 2, in a vehicle front-rear direction, a vehicle up-down direction and a vehicle right-left direction. The interior unit 10 is disposed in an instrument panel within a passenger compartment, at an approximate center in the vehicle right-left direction.
As shown in FIG. 1, the interior unit 10 includes a blower 11 disposed at a lower side portion in the vehicle up-down direction, a heat-exchanging portion 12 disposed at a middle portion in the vehicle up-down direction, and a mode switching portion 13 disposed at an upper side portion in the vehicle up-down direction. That is, the blower unit 11, the heat-exchanging portion 12 and the mode switching portion 13 of the interior unit 10 are arranged in the vehicle up-down direction to construct a vertical layout. Inside/outside air introduction ducts 14, 15 are disposed at both right and left sides of the elements 11-13 of the interior unit 10.
