Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improving the appearance of an air conditioner installed on the ceiling of a passenger compartment of an automobile.

[0002]

2. Description of the Related Art In the air conditioning of a one-box automobile, an indoor unit for supplying conditioned air to the seats in the middle and rear of the passenger compartment is provided in the ceiling portion. This indoor unit has a configuration in which a cooling unit is horizontally arranged on the ceiling of a vehicle compartment, and a refrigerant evaporator, a blower and the like are housed in a unit case. The cooling unit is mainly supplied with the refrigerant supplied by the outdoor unit mounted in the engine room, and the conditioned air is supplied into the vehicle compartment from the refrigerant discharge port provided in the unit case. In order to uniformly supply this conditioned air to all seats in the passenger compartment, an extension duct is connected to the discharge port, and the conditioned air is blown to each seat from the outlet provided in the extension duct. . Further, usually, this type of cooling unit is decoratively covered with a unit cover in order to improve the appearance and prevent noise.

[0003]

However, in the conventional indoor unit of the air conditioner for an automobile of this type, since the connecting portion between the unit case and the extension duct is exposed in the passenger compartment, it lacks a sense of quality and prevents noise. It was not enough. An object of the present invention is to provide an air conditioner for a vehicle, which has a good-looking air conditioner mounted on the ceiling of a vehicle cabin, has a high-grade feeling, and can realize low noise.

[0004]

An air conditioner for a vehicle according to the present invention comprises a cooling unit mounted on a vehicle compartment ceiling of an automobile and an air conditioner connected to a discharge port of the cooling unit and fixed to the vehicle compartment ceiling. It is characterized by comprising an extension duct provided with an outlet for air to the vehicle compartment, a unit cover for covering the cooling unit, and an intermediate cover for covering a connection portion between the cooling unit and the extension duct.

[0005]

According to the present invention, since the connecting portion between the cooling unit and the extension duct is covered with the intermediate cover, the intermediate cover makes the connection between the unit cover and the extension duct smooth, and the appearance is high-quality. In addition to being excellent, it is possible to reduce noise such as blower.
