DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle air conditioner according to the present invention will be described with reference to FIGS. 1 to 3. In FIG. 1, 1 is an air conditioner, and 2 is a compressor horizontally arranged at the end in the longitudinal direction and the end in the width direction. Reference numeral 3 indicates an indoor fan whose axial direction is vertically arranged, and reference numeral 4 indicates an indoor heat exchanger arranged adjacent to the indoor fan 3. The compressor room in which the compressor 2 is installed is equipped with an indoor fan 3.
and is arranged adjacent to the indoor equipment room in which the indoor heat exchanger 4 is provided. Further, the axial direction of the compressor 1 is arranged in the longitudinal direction of the air conditioner 1 . Reference numeral 5 denotes an outdoor fan, which is disposed at the center of the air conditioning bag in the longitudinal and width directions. 6 is an air conditioner 11 for the outdoor fan 5
(This is an outdoor heat exchanger placed on both sides in the width direction of l.
Reference numeral 2 designates return ports arranged adjacent to both sides of the air conditioner 1 in the longitudinal direction in an outdoor equipment room in which the outdoor fan 5 and the outdoor heat exchanger 6 are provided. ! Reference numeral 3 denotes an electrical equipment box installed at a diagonal position in the air conditioner ll at the position where the compressor room is provided. In addition, the detailed structure of the front indoor fan 3 will be explained. 8 is a driving motor, and 9 is an impeller having a structure in which fins are arranged on the outer circumference of the motor 8. The impeller 9 has a space at its axial center position into which the motor 8 can be inserted, and is configured such that its axial dimension overlaps with the axial dimension of the motor 8. 1O is a casing that surrounds the outer circumference and axial direction of the impeller 9 and forms an air suction port 11.

According to such a configuration, by arranging the compressor room adjacent to the indoor equipment room at a position in the vertical direction of the equipment W1, and arranging the compressor l in the longitudinal direction of the equipment, the indoor equipment room and the compressor room can be separated. and can be arranged compactly.
