In general, an air conditioner installed in a vehicle includes a cooling system for cooling the interior of a vehicle, and a heating system for heating the interior of the vehicle.

The cooling system compresses the refrigerant to a condenser by a compressor driven by the power of the engine, and condenses the refrigerant by forced air of the cooling fan in the condenser.

In the process of returning back to the compressor through the receiver dryer, the expansion valve and the evaporator in turn, the refrigerant exchanges heat between the air blown by a blower unit installed at the inlet end of the air conditioning case and the refrigerant passing through the evaporator. Cools the inside of the vehicle by discharging the blown air that has become cold.

In addition, the heating system heat-exchanges the air blown by the blower fan of the blower unit and the cooling water passing through the heater core in the process of returning the engine cooling water to the engine through the heater core. The vehicle interior is heated by discharging the vehicle interior.

However, a general vehicle air conditioner is configured to discharge air for cooling or heating from a vent duct installed in an instrument panel in front of a vehicle interior, such as a four-wheeled vehicle such as a luxury car or a van or RV. In the case of a driving vehicle, the cooling or heating effect is insufficient to the rear seat.

In the case of a vehicle having a large indoor space as described above, in order to assist the cooling and heating performance of the rear seats, a separate rear air conditioner (also referred to as a 'rear seat air conditioner') is usually installed in a limited space of the side wall of the body on the rear wheel cover. have.

In particular, the rear air conditioner has a vent outlet for discharging cold or warm air to the roof side of the vehicle at the 'C' pillar of the vehicle (a pillar between the rear seat door and the rear glass in a luxury car). Or a 'D' pillar (a pillar between the trunk glass and the rear glass in a four-wheel drive vehicle).

The conventional rear air conditioner has a blower passage having an inner air inlet (not shown) at one end thereof and communicates with a vent duct for blowing air from the blower chamber to the roof side of the vehicle at the other end thereof. A vent outlet and a floor outlet communicating with a floor duct for blowing air to the floor of the vehicle is formed.

The rear air conditioner is provided with a mode door so that the wind can be discharged to the discharge port selected by the user, the mode door is a smooth mode to discharge the air when operating in the floor mode or vent mode, but the mixture of the floor mode and the vent mode When operating in the form of the bi-level mode, the door is interrupted by the wind discharged from the ventilation chamber, and a pressure loss is generated, thereby causing a problem of noise.

The above phenomenon has a problem of causing a dissatisfaction with the vehicle by dropping the interior quietness of the vehicle due to noise induced to the passengers in the vehicle.

The present invention has been made to solve the above problems, by folding the dome-shaped door door in the bi-level mode, to provide a vehicle rear air conditioning apparatus that can be used to minimize the noise generated by the wind resistance generated in the bi-level mode. Its purpose is to.

The present invention for achieving the above object, the support is installed on the air-conditioning housing and the inner side in contact with the surface is installed to operate in the follower mode, vent mode and bi-level mode is folded in the bi-level mode operation It is characterized in that to provide a vehicle rear air conditioning apparatus, characterized in that the domed mode door unit is provided to minimize the resistance of the wind discharged.

The domed mode door part is connected between the first mode door formed in an arc shape and the second mode door installed to be foldable with the first mode door and the first and second mode doors. It is configured to include an elastic member that provides a folding operation force.

Preferably, the elastic member uses a spring, but it is also possible to use another member having a similar or similar function to that of the spring.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
