Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle air conditioner, and more particularly to a vehicle air conditioner which can be made compact and which can greatly improve air conditioning for the rear seats.

[0002]

2. Description of the Related Art As an air conditioner mounted on a vehicle, the temperature of both the outside air introduced into the vehicle from the outside and the inside air circulating in the vehicle or either one of them is controlled by manual or automatic operation so that the temperature becomes appropriate. BACKGROUND ART A so-called full air mix type air conditioner configured to be blown out into a vehicle compartment through a blowout port has been conventionally known. The air conditioner is disposed in the space below the dash panel and below the dashboard that separates the engine room from the vehicle interior.

Of the air conditioners of this type, the full air mix type air conditioners mounted on passenger cars are generally classified into high class cars, middle class cars and popular cars.

[0004] To briefly describe the respective structures, high-class automobiles often employ a structure in which an air conditioner dedicated to the rear seats is provided in a system different from the air conditioner provided for the front seats. It is often practiced to provide an air conditioner dedicated to the rear seats (hereinafter referred to as a rear seat air conditioner) in the rear trunk room.

As a typical configuration example of the rear seat air conditioner thus arranged, only the refrigerant pipe is provided between the front engine room and the rear trunk room, while only the inside air of the passenger compartment is arranged in the rear seat air conditioner. After being introduced into the interior, the refrigerant is passed through the core of a dedicated evaporator that is piped with a refrigerant to cool it, and then blown out toward the rear seat from a vent provided in a pillar or the like near the rear seat.

Next, the structure of the air conditioner for a middle-class vehicle is, for example, as disclosed in Japanese Utility Model Laid-Open No. 63-66309, for the front seat to blow out the conditioned air to the rear seat. A rear duct extending from the air conditioner to the rear seat is provided, and the inside and outside air conditioned is blown to the rear seat via a center console vent and a rear foot vent provided as a rear seat vent.

In the air conditioner for popular vehicles, only the front seat is subjected to air conditioning to reduce the cost.

[0008]

As described above,
A conventional air conditioner does not interfere with the steering shaft, accessories or meters installed on the dashboard in the space behind the dashboard and below the dashboard that separates the engine room from the passenger compartment, and in the lateral direction of the vehicle body. Since it must be arranged so as to avoid the cross member of the reinforcing member to be arranged, it is arranged so as to occupy the space below the glove bots on the passenger side where the number of attached parts is relatively small. In many cases, the space under the foot is limited, and the so-called living space is limited.

Further, since the conventional air conditioner is arranged in a space below the dashboard, which is a so-called gap,
It is very inferior in the assembling property, and becomes a hindrance when realizing, for example, automatic assembly.

Therefore, the vehicle air conditioner of the present invention has been made in view of the above problems, and the purpose thereof is to realize fine air conditioning for the front seat and the rear seat with an inexpensive and compact structure. Another object of the present invention is to provide a vehicle air conditioner that does not affect the living space in the vehicle compartment, has excellent assembling properties of the air conditioner, and can increase the strength of the vehicle body.
