A vehicle air conditioning system has an interior unit in which a width dimension, that is, a dimension parallel to the width of the vehicle, is smaller than competing devices. A blower unit, an evaporator as a cooling heat exchanger, and a heater core as a heating heat exchanger are integrally disposed inside a casing for blowing air toward a vehicle compartment. A face passage is formed above the heater core such that the temperature-controlled air passes through the heater core and is lead to a face opening by the face passage. A foot passage is formed inside the casing and above the heater core so as to protrude from the rear face of the casing toward the face passage. A foot door for opening and closing a foot opening of the foot passage is disposed inside the face passage.

1. Field of the Invention
The present invention relates to a vehicle air-conditioning system interior unit in which an interior dimension, with respect to a cross direction of the vehicle, is reduced.
The present invention will become more fully understood from the detailed description and the accompanying drawings, wherein:
FIG. 1 is a cross-sectional view of an interior unit according to an embodiment of the present invention;
FIG. 2 is an enlarged cross-sectional view of an essential part of the interior unit in FIG. 1;
The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
Now, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic cross-sectional view showing a configuration of an interior unit 10 of a vehicle air-conditioning system according to this embodiment. FIG. 2 is an enlarged cross-sectional view of an essential part of the interior unit 10. The interior unit 10 is disposed approximately in the center in a width (right-to-left) direction of a vehicle inside an instrument panel (not shown) in front of the passenger compartment, with respect to the vehicle orientation. Along these lines, the interior unit 10 is installed as necessary with respect to the vertical and horizontal directions of the vehicle as indicated by the locational arrow legend in FIG. 1. Additionally, the width direction of the vehicle is the direction perpendicular to the sheet on which FIG. 1 is located.
FIGS. 4 and 5 show representative examples of the location of the interior unit 10 within a vehicle 32. FIG. 4 shows the vehicle 32 with an interior unit 10 located proximate to the front of the vehicle 32. The vehicle interior compartment 34, which is to be heated and/or cooled by the interior unit 10 is shown by a dashed line. The interior unit 10 is located proximate to the vehicle front windshield 36 for heating and/or cooling the surface of the windshield 36. FIG. 5 is a front view of a vehicle 32 showing a representative location of the interior unit 10 below the vehicle windshield 36 and its left-to-right position relative to the width of the vehicle 32. In FIG. 5, the interior unit 10 is shown in a central location with respect to the width of the vehicle 32.
