Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, the front air conditioning apparatus 100 installed on the front side of the vehicle interior is installed inside a dashboard 101 of the vehicle interior.

The front air conditioning apparatus 100 includes an air conditioning case (not shown) having an evaporator (not shown) for cooling the air and a heater core (not shown) for heating the air, And an air blowing device (not shown) for blowing air or outside air to the air conditioning case.

In addition, a temperature control door (not shown) is provided in the air conditioning case to control the temperature of the air passing through the evaporator by regulating the amount of air passing through the heater core and air bypassing the heater core, And a mode door (not shown) installed on the side of the air discharge opening of the air conditioning case for adjusting the air discharge direction according to the air discharge mode.

A plurality of discharge ports 102 for supplying the air discharged from the front air conditioning apparatus 100 to the vehicle interior are formed on the dashboard 101 side.

Accordingly, during operation of the front air conditioning apparatus 100, air blown from the air blowing device flows into the air conditioning case and passes through the evaporator and the heater core. At this time, air passing through the heater core And the temperature of the air is adjusted by controlling the amount of air bypassing the heater core. After the direction of air is adjusted by the mode door, the air is blown into the passenger compartment through the discharge port 102 of the dashboard 101.

In addition, when the number of stages of the air blowing apparatus is the highest, the air blown through the discharge port 102 of the dashboard 101 flows not only to the front seat space A but also to the rear seat space B, Comfort is improved not only for the passengers but also for the passengers in the rear seats,

The air blown through the discharge port 102 of the dashboard 101 flows only to the front seat space A of the vehicle and does not flow into the rear seat space B, Even if it flows into the rear seat space (B), the flow amount thereof is small and the comfort of the rear seat occupant is lowered.

Accordingly, in the present invention, the auxiliary blower 120 is installed such that the air discharged into the front seat space A through the front air conditioning apparatus 100 is sufficiently circulated to the rear seat space B.

The auxiliary blower 120 is installed on the indoor side of the vehicle and sucks the in-vehicle air and blows it back to the inside of the vehicle to improve the fluidity of the room air.

The auxiliary blower 120 is installed so as to be embedded in the interior of the vehicle so as not to be seen by the naked eye of a passenger in the vehicle interior. More specifically, the auxiliary blower 120 is installed between the rear seat 105 of the vehicle and the rear window 106 of the vehicle And the air in the rear compartment space B of the vehicle flows in the direction of the front seat so as to circulate air in the passenger compartment.

That is, when the auxiliary blower 120 operates, air in the rear seat space B of the vehicle is sucked and blown toward the front seat. As a result, air in the front seat space A flows into the rear seat space B So that the fluidity of the indoor air can be improved.

When the fluidity of the vehicle interior air is improved by the auxiliary blower 120, the mixing of the air in the front seat space A and the air in the rear seat space B is improved, And the comfort is improved.

5 is a graph showing the temperature of the rear seat space B depending on the presence or absence of the auxiliary blower 120 during the automatic control of the front air conditioning apparatus 100. When the auxiliary blower 120 is not installed, The temperature was measured at the head of the passenger in the rear-seat space (B).

As can be seen, when the set temperature of the front air conditioning apparatus 100 is set to 21 ° C, 23 ° C and 25 ° C, the temperature of the rear seat space B when the auxiliary blower 120 is not attached is 25.0 ° C and 27.0 ° C And 28.6 캜, respectively, and the temperature in the rear seat space (B) when the auxiliary blower 120 was mounted was measured at 24.0 캜, 25.9 캜, and 27.1 캜, respectively.

That is, it can be seen that the temperature of the rear-seat space B is lowered when the auxiliary blower 120 is mounted on the basis of the set temperature. This is because, by mounting the auxiliary blower 120, The flow of air is improved so that the air blown into the front seat space A through the front air conditioning apparatus 100 smoothly circulates to the rear seat space B and the temperature deviation of the rear seat space B is reduced compared to the set temperature, The sex is improved.

Particularly, as the blower is controlled to a lower number, the auxiliary blower 120 greatly contributes to improvement of the flowability of the room air.

6 is a graph showing the temperature deviation between the head and the foot of the passenger in the rear seat space B depending on the presence or absence of the auxiliary blower 120 during the automatic control of the front air conditioning system. When the blower 120 is mounted, the temperature deviation between the head and the foot of the passenger in the rear-seat space B is measured.

When the set temperature of the front air conditioning apparatus 100 is set to 21 ° C., 23 ° C. and 25 ° C., when the auxiliary blower 120 is not mounted, the temperature of the head of the passenger in the rear seat space B and the temperature The deviation was measured at 2.6 캜, 3.9 캜 and 3.8 캜, respectively. When the auxiliary blower 120 was mounted, the temperature deviation between the head of the occupant and the foot of the rear seat space B was 0.8 캜, 2.0 캜 and 1.5 캜 Respectively.

That is, it can be seen that the temperature difference between the head and the foot of the passenger in the rear seat space B is reduced when the auxiliary blower 120 is mounted. By mounting the auxiliary blower 120, The fluidity of the indoor air is improved, and the air in the head and the feet of the passenger in the rear-seat space B smoothly circulates, so that the temperature deviation is reduced and the comfort is improved.

The auxiliary blower 120 is installed on the lower side of the rear seat tray 110 so as not to be viewed by the passenger in the passenger compartment.

The rear seat tray 110 is provided with a suction grill part 111 for sucking the air in the rear seat space B toward the auxiliary blower 120 when the auxiliary blower 120 operates, To be discharged to the rear window glass 106 side is formed.

Therefore, when the auxiliary blower 120 operates, the air in the rear seat space B passes through the suction grille 111 and is sucked into the auxiliary blower 120, and then, The air is blown to the rear window glass 106 side through the discharge grill portion 112.

The air blown toward the vehicle rear window 106 is guided along the inclined surface of the rear window glass 106 and flows in the front seat direction. At this time, the air in the front seat space A flows into the rear seat space B, The air in the vehicle interior is circulated and the mixing performance of the indoor air is improved.

A filter 115 is installed below the suction grille 111 to remove dust contained in the air sucked into the auxiliary blower 120.

Therefore, when the auxiliary blower 120 operates, when the air is sucked into the suction grill part 111, the dust contained in the air passes through the filter 115 to remove the durability of the auxiliary blower 120 And the comfort of the interior of the vehicle is further improved.

On the other hand, it is preferable that the auxiliary blower 120 uses a cross fan having excellent wind direction and diffusibility.

Hereinafter, the operation of the vehicle air conditioner according to the present invention will be described, and a case where the front air conditioner 100 is automatically controlled will be described as an example.

First, when the occupant sets the temperature of the automatically controlled front air conditioning apparatus 100, the control unit (not shown) controls the temperature of the air discharged from the front air conditioning apparatus 100, The temperature is adjusted to a certain temperature.

At this time, the air discharged from the front air conditioning apparatus 100 is blown into the front seat space A of the passenger compartment through the discharge ports 102 of the dashboard 101, Since the wind flows to the seat (B) as well as the seat, it is possible to improve the comfort by reducing the temperature deviation of the rear seat space (B).

Therefore, when the blower is at the highest level, the controller turns off the auxiliary blower 120 to improve the fuel efficiency of the vehicle. Of course, the auxiliary blower 120 can be operated even when the air blowing device is at the maximum number of stages. In this case, since the fluidity of the in-vehicle air is further improved, the temperature deviation in the vehicle interior can be further reduced and the comfort can be further improved.

If the air blowing device is not at the highest level, the air flowed into the front seat space A through the front air conditioning apparatus 100 does not flow to the rear seat space B, The temperature difference of the rear seat space B may be increased and the comfort may be lowered. Therefore, in the present invention, when the air blowing device is not at the highest level, the auxiliary blower 120 is operated to improve the fluidity of the room air.

That is, when the auxiliary blower 120 is operated, the air in the rear seat space B is sucked into the auxiliary blower 120 and blown in the direction of the front seat, and the front air- The air in the front passenger compartment 100 is discharged from the front passenger compartment 100 while the air in the front passenger compartment 100 in which the temperature is controlled by the passenger compartment 100 flows into the rear seat space B, Will circulate all the seats in the vehicle, reducing the temperature deviation of all the seats and improving the comfort.

Meanwhile, it is preferable that the rotation speed (number of steps) of the auxiliary blower 120 is variably controlled according to the number of stages of the blower or various conditions of the vehicle to minimize noise.
