DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for a vehicle, which can easily remove and attach an air conditioning component constituting an air conditioning unit mounted inside an instrument panel of a vehicle.

[0002]

2. Description of the Related Art In recent years, it has been proposed to modularize components disposed in front of a passenger compartment including an instrument panel, for example, as disclosed in Japanese Patent Application Laid-Open No. H11-59162.
In the publication, an air conditioning unit or the like is attached to a steering member, and a unit assembly is formed by attaching a display device to the air conditioning unit.
There has been proposed a device in which an instrument panel is attached so as to cover the unit assembly after the unit assembly is attached to a vehicle body.

In general, an air conditioning unit is an air conditioning component such as an inside / outside air switching device for adjusting the ratio of introduction of inside air to outside air, a blower, a cooling heat exchanger, a heating heat exchanger, and a blowing mode switching device for switching a blowing mode. Are arranged in series with respect to the flow of the wind, but in the above-described module configuration, maintenance is required for each air-conditioning component by removing the instrument panel and then performing maintenance. It is necessary to remove the air conditioning components from the air conditioning unit.

[0004]

However, if the instrument panel is raised and lowered one by one at the time of maintenance, the work efficiency is poor, and the instrument panel itself is large and heavy, so that the instrument panel is heavy. It was not easy to attach and detach, and it was a major obstacle during maintenance. Therefore, maintenance is becoming an important issue in modularizing the air conditioning unit and the instrument panel.

Therefore, in the present invention, in particular, the blower, the cooling heat exchanger, the heating heat exchanger, and the blow-out mode switching device are arranged at substantially the same position in the vehicle width direction, and the inside / outside air switching device is provided in the blower. In order to place the air conditioning unit, which is arranged offset in the vehicle width direction, inside the instrument panel, repair or replace the air conditioning parts without lowering the instrument panel.
