The present invention relates to a vehicle air conditioning unit, and in particular, by allowing the air discharged through the discharge port of the air conditioning unit to be uniformly discharged, since the air supplied to the defrost duct is equally distributed to the driver's seat and the passenger's seat, uniform defrosting on the windshield of the vehicle. It relates to a flow path structure of the vehicle air conditioning unit to make the work.

In general, a vehicle air conditioning unit (HVAC UNIT: Heating, which allows external air to be introduced into a vehicle interior to ventilate the air inside the vehicle, or recycles and heats and cools by recirculating already introduced air). Ventilating and Air Conditioning are installed.

The air conditioning unit 10 forms a predetermined space, and the inlet and outlet 20 are formed, and the evaporator core 14 and the heater core 12 are installed therein, and a plurality of doors are installed to circulate air. The heat is exchanged so that the temperature of the air discharged into the vehicle interior can be controlled according to the driver's operation.

Here, the discharge port 20, as shown in Figure 2, by the other devices installed in the driver's seat is formed in the driver's side narrower than the auxiliary seat, the size of the discharge port 20 is a defrost duct (not shown) An expansion portion 30 is formed in which the discharge port on the driver's seat side extends in the lateral direction so as to correspond to the suction port of the driver's seat.

As a result, the air discharged from the air conditioning unit is reduced to a certain amount or less compared to the amount of air discharged from the driver's seat side to the passenger seat side.

The amount of air supplied to the defrost duct is not uniform between the driver's seat side and the passenger seat side by the discharge port structure of the air conditioning unit as described above, and the amount of air supplied to the driver's seat side along the extension part 30 is small. The amount of air discharged to the furnace is also not equal, and thus, there is a problem that the defrosting operation is not uniform over the entire windshield.

The present invention has been made to solve the above problems of the prior art, by improving the discharge port flow path of the air conditioning unit, the amount of air discharged to the driver's seat side and the amount of air discharged to the passenger seat side is evenly distributed, so the amount of air supplied to the defrost duct It is an object of the present invention to provide a flow path structure of an air conditioning unit for a vehicle that is uniform so that defrosting work on the windshield of the vehicle can be performed evenly.

The flow path structure of the vehicle air conditioning unit according to the present invention for solving the above problems, the discharge port formed on one side of the air conditioning unit of the vehicle and in communication with the defrost duct, one side of the discharge port corresponding to the driver's seat inclined laterally And an extended extension part and a guide rotatably installed inside the discharge port so that a predetermined amount of air is switched in the direction of the expansion part according to the amount of air discharged through the discharge hole, and the guide is not formed with the extension part. Characterized in that arranged on the other side of the discharge port.

Hereinafter, an embodiment of a flow path structure of a vehicle air conditioning unit according to the present invention will be described in detail with reference to the accompanying drawings.

3 is a cross-sectional view showing a flow path structure of a vehicle air conditioning unit according to the present invention, Figure 4 is a cross-sectional view showing a state of use of the vehicle air conditioning unit according to the present invention.

The flow path structure of the vehicle air conditioning unit according to the present invention, the discharge port 50 is formed on one side of the air conditioning unit of the vehicle and communicate with the defrost duct, and one side of the discharge port 50 corresponding to the driver's seat is inclined in the lateral direction The expansion unit 60 and the guide 70 which is rotatably installed inside the discharge port 50 so that a predetermined amount of air is switched in the direction of the expansion unit 60 according to the amount of air discharged through the discharge port 50. It is configured to include.

Here, the expansion unit 60 is to widen the discharge port 50 so that the intake port of the defrost duct of the vehicle and the intake port of the air conditioning unit communicate with each other. 50 is a structure that cannot be widened to the driver's seat side.

The guide 70 is disposed at the other side of the discharge port 50 in which the expansion part 60 is not formed, and the guide 70 is a guide panel rotatably installed inside the discharge port 50 ( 74, the guide panel 74 penetrates the rotary shaft 72 provided in the discharge port 50, and the discharge port 50 corresponding to the guide panel 74 is installed on the inner wall of the rotation of the guide panel 74 The stopper 76 is configured to include a quantity controlled.

Here, the guide panel 74, as shown in Figure 5, the hole portion 74a is inserted into the rotating shaft 72, the first angle bent to the outside of the discharge port 50 around the hole portion 74a The first panel 74b and the second panel 74c extending in the horizontal direction about the hole 74a are included.

As a result, the guide panel 74 bent at a predetermined angle is rotatably installed inside the discharge port 50. When air is discharged to the outside of the discharge port 50, the guide panel 74 is driven about the rotation shaft 72. The other side of the expansion unit 60 and the expansion unit 60 is rotated at an angle at which an equal amount of air is distributed to allow an even distribution of the discharged air.

In addition, the first panel 74b is formed to be relatively long compared with the second panel 74c so that air impinged on the guide is guided to the expansion unit 60 along the first panel 74b. In addition, the amount of air discharged to the expansion portion 60 is increased by allowing the amount of air guided by the first panel 74b to be relatively larger than the amount of air guided by the second panel 747c. Make sure to achieve the same amount of air discharged to the other side.

In addition, the stopper 76 is a protrusion for preventing the guide panel 74 from being reversely rotated. The stopper 76 protrudes from the inside of the discharge port 50 so as to correspond to the inner wall of the second panel 74c. By preventing 74c) from being rotated inside the discharge port 50 in a state in which it is disposed to be orthogonal to the discharged air, the guide is not reversed by the first panel 74b in which more flow path resistance is formed.

Looking at the operation of the flow path structure of the vehicle air conditioning unit according to the present invention configured as described above are as follows.

First, if frost or moisture is generated on the windshield during operation, and the user's vision is obstructed, the blower is driven by the user's operation to introduce air into the air conditioning unit, and the heat exchange of air through the heater core or the evaporator core is performed. After the air is introduced into the defrost duct through the discharge port 50.

Air supplied in this way is sprayed on the inner wall of the windshield through the defrost duct to perform the defrost operation to ensure the driver's view.

At this time, the air supplied to the defrost duct along the discharge port 50 of the air conditioning unit is supplied to the expansion unit 60 while colliding with the guide 70, the first panel of the guide panel 74 The air collided with 74b is switched in the flow direction toward the expansion unit 60, so that the amount of air discharged along the expansion unit 60 and the amount of air discharged to the other side of the discharge port 50 are equally distributed.

In addition, the guide panel 74 is installed to be rotatable by the rotation shaft 72, and according to the amount and intensity of air discharged through the discharge port 50, the first panel 74b and the second panel 74c are Since the guide panel 74 is installed on the rotation shaft 72 in a somewhat interference fit manner, the guide panel 74 initially fixed is determined if air of a higher intensity is not discharged. The position of the guide panel 74 is not changed.

Thus, after the amount of air discharged along the discharge port 50 is evenly distributed, the position of the guide panel 74 is fixed so that the air is always discharged evenly.

As a result, the air discharged from the defrost duct is also equally distributed to the driver's seat and the passenger seat, so that a uniform defrosting operation is performed over the entire windshield of the vehicle.

In the flow path structure of the vehicle air conditioning unit according to the present invention configured as described above, the guide panel bent at a certain angle is rotatably installed inside the discharge port, the air discharged according to the amount and intensity of the discharged air can be evenly distributed. By doing so, since the air supplied to the defrost duct is uniformly supplied in the left and right directions, defrosting work is simultaneously performed to remove frost and moisture all over the windshield, so that the driver can drive safely.

In addition, the flow path structure of the vehicle air conditioning unit according to the present invention, the stopper is provided so that the guide panel is not reversely rotated, the front of the guide is prevented because the amount and intensity of the air discharged to the discharge port of the air conditioning unit is prevented from varying The uniform defrosting operation is performed throughout the glass, and at the same time, there is an advantage that a safe operation that prevents malfunction and breakage of the air conditioning unit can be achieved.

In addition, since the guide panel is rotatably installed, the guide panel is rotated so that the amount of air distributed to the expansion part and the other side of the discharge port is equalized according to the amount and strength of the air discharged along the discharge port. Since it can be applied to a variety of different vehicles, each time a new model vehicle is developed, there is an advantage that it can be easily applied without separately designing the shape of the guide.
