First, before looking at the vehicle blowing unit filter apparatus according to the present invention, a brief description of the blowing unit of the air conditioner.

The air blowing unit includes an air conditioner case 10, and the air conditioner case 10 is provided with an outside air inlet 20 and an air inlet 15. The outside air inlet 20 introduces air outside the vehicle into the air conditioning case 10. The bet inlet 15 introduces indoor air into the air conditioning case 10.

In addition, the blower unit includes an internal / external air switching door 25 that selectively blocks any one of the external air inlet 20 and the internal air inlet 15.

As shown in FIG. 2, the internal / external air switching door 25 is provided with an upper plate part 40 which can selectively block the internal air inlet 15 and the external air inlet 20, and the upper plate part ( The side plate part 35 is provided in both sides of 40).

In addition, the sealing member 85 is formed on the outer circumferential surface of the upper plate portion 40. Here, the sealing member 85 is provided to maintain the airtightness in the internal and external air switching door 25 to selectively block the inflow of air from the internal air inlet 15 and the external air inlet 20.

The internal and external air conversion door 25 is capable of rotating in the air conditioning case 10, as shown in FIGS. 5 and 6, between the first position (I) and the first position (II). Rotate

In addition, the upper plate portion 40 directly blocks the outside air inlet 20 or the inside air inlet 15. In particular, as the internal / external air switching door 25 is positioned at the front first position (I), the outdoor air inlet 20 is blocked, and the internal / external air switching door 25 is located at the rear first position (II). As it is arranged to block the bet inlet (15). The internal / external air switching door 25 of this form is formed in a dome form.

On the other hand, the ventilation unit filter unit for an air conditioning system according to the present invention is installed on the outside of the internal and external air switching door 25, the internal and external air switching is arranged on the inside air inlet 15 or the outside air inlet 20 side. A filter driving door 45 of a dome type is disposed to filter the air that is disposed toward the other part of the door 25.

The filter driving door 45 may include a filter mounting unit 58 forming a main body and corresponding to the upper plate unit 40, and a rotation shaft of the internal and external air conversion doors 25 at both sides of the filter mounting unit 58. A filter rotation shaft 70 is rotatably assembled to the same line as 30. In addition, a filter side plate portion 75 connecting the filter rotation shaft 70 and the filter mounting portion 58 is formed.

Here, the sealing member 85 is formed on the outer circumferential surface of the filter mounting portion 58, which is in contact with the internal and external air switching door 25 and the airtightness is maintained to block the inflow of air.

As shown in FIGS. 5 and 6, the filter rotation shaft 70 is installed in the air conditioning case 10 so as to be rotatably installed in the same line as the rotation shaft 30 formed on the internal / external air switching door 25. . The internal / external air switching door 25 and the filter driving door 45 rotate in opposite directions, and are driven by different actuators (not shown).

In addition, the opening part 50 formed in the filter mounting part 58 is provided with a filter member 59 installed to correspond to the upper plate part 40. As shown in FIG. 4, the filter member 59 of the filter mounting unit 58 is formed in a dome shape corresponding to the upper plate portion 40 of the internal / external air switching door 25. It has a thickness of about 12mm.

In addition, grooves 60 for mounting on the filter mounting portion 58 are formed at both ends of the filter member 59. It is formed on both sides of the filter mounting portion 58, the protrusions 65 are formed, it is possible to mount the grooves 60 to the protrusions 65, it is also coupled by the dovetail (Dovetail) method of groove fit. This is possible.

Next, an operation example of the present invention having such a configuration will be described with reference to FIGS. 5 and 6.

First, Figure 5 is a view showing the operating state when the blowing unit filter device is in the bet mode, the filter drive door 45 is rotated about the filter rotation axis 70 when air is introduced to the bet inlet 15 side It is arranged in the first position (I) to filter the air. On the other hand, the internal and external air switching door 25 is disposed in the second position (II) which is the direction opposite to the filter driving door 45 to block the introduction of air to the outside air inlet 20.

FIG. 6 is a view illustrating an operation state when the blower unit filter device is in the external air mode, and the filter driving door 45 and the internal / external air switching door 25 are rotated in the opposite direction to the internal air beating mode of FIG. 5. Is placed in the changed state. Accordingly, the internal / external air switching door 25 blocks the air introduction of the internal air inlet 15, and the filter driving door 45 filters the air introduced from the external air inlet 20.

Meanwhile, as illustrated in FIG. 7, the internal / external air switching door 25 and the filter driving door 45 may be disposed to overlap either the internal air inlet 15 or the external air inlet 20. . This is because when the degree of air pollution introduced in the internal mode or the external mode is weak, the internal / external air switching door 25 and the filter driving door 45 are overlapped in accordance with the internal or external mode, so that the amount of air flowing into the open portion is increased. The air volume can be increased by doubling and further, the overlapping part has an effect of maximizing the sealing property.

On the other hand, in the modification of the filter drive door 45, as shown in Figure 8, the auxiliary filter member 80 is provided on both sides of the filter side plate portion 75. Here, by providing the auxiliary filter member 80, to ensure a sufficient filter area from the air introduced into the outside air inlet 20 or the inside air inlet 15 for each bet or outside air mode, the auxiliary inlet inlet 80a Air is introduced through the) to purify the air introduced from the auxiliary filter member (80).

At this time, air is introduced through portions formed in the filter side plate portions 75 formed at the filter driving doors 45, respectively, to be opened as much as the area of the auxiliary filter member 80 formed at the air conditioning case 10.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.

As described above, according to the air blowing system filter unit for an air conditioning system according to the present invention, the filter unit is provided on the inside and outside air inlet side in a form corresponding to the internal and external air door in the form of a dome, inflow of the internal and external air. Since only the position to be filtered depending on whether or not, the volume of the air conditioning case can be greatly reduced and the manufacturing cost can be reduced.
