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 an air conditioner for a middle-class vehicle, as disclosed in, for example, Japanese Patent Application No. 63-66309, is designed for the front seats to blow out the conditioned air to the rear seats. A rear duct extending from the air conditioner to the rear seat is provided, and the inside / outside air conditioned is blown to the rear seat through 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 is a hindrance when realizing, for example, automatic assembly.

Further, among the conventional full air mix type air conditioners, those for luxury vehicles have an advantage that the air conditioning for the rear seats can be performed independently of the front seats by providing the above-mentioned rear seat air conditioner. However, since a rear seat air conditioner provided in the rear trunk room and piping for the refrigerant thereof are inevitably required, there are problems that the cost increases and there is a drawback that the air conditioner uses only the inside air.

In the case of the intermediate class vehicle, the inside and outside air after air conditioning is delivered to the rear seats through the rear seat vent extended from the air conditioner provided for the front seats as described above. It has a merit that it can be constructed relatively inexpensively because it is configured to blow out, but as a result of temperature change in the process of passing cold and warm air after air conditioning for long rear seat vents, There was a drawback that the rear seats could not be air-conditioned like the seats.

Further, although the one for a popular vehicle can be realized at a low cost, it has a drawback that an air conditioning target is limited to a front seat.

Therefore, the vehicle air conditioner of the present invention has been made in view of the above problems, and the object of the first invention is to provide a fine and air-conditioned air conditioner for the front and rear seats at a low cost and in a compact size. An object of the present invention is to provide an air conditioning system for a vehicle that can be realized with a configuration.

The object of the second invention is as follows.
By arranging an air conditioner, it does not affect the living space inside the vehicle, the air conditioner is easy to assemble, and fine air conditioning can be realized for both the front and rear seats or only the front seat. An object of the present invention is to provide a vehicle air conditioner that enables an air conditioner with an inexpensive structure.

[0015]
