It may include a blower unit 120 to supply to. In this case, the intake unit 110 and the blower unit 120 may share one case, but is not limited thereto. Here, the intake unit 110 may be disposed on the rear side of the blower unit 120 . In detail, the intake unit 110 may be disposed on the front-rear direction, which is the x-direction of the blower unit 120 .

The intake unit 110 of the blower unit 100 includes two outdoor air inlets 112 and 113 and one indoor air inlet 114 to facilitate the inflow of outside air while also having a partition wall 115 and a plurality of intake doors. (116) can be used to control the amount of outside air inflow. Here, the partition wall 115 may be referred to as an intake partition wall.

3 to 5 , the intake unit 110 includes an intake case 111 having a space therein, and a first outdoor air inlet 112 and a second outdoor air inlet 113 formed in the intake case 111 . and a bet inlet 114 , and a partition wall 115 and a plurality of intake doors 116 disposed in the space.

In addition, in order to prevent the introduction of foreign substances falling into the intake case 111 through the first outdoor air inlet 112 disposed on the intake case 111, the intake unit 110 is A cover 117 disposed to cover the first outdoor air inlet 112 may be further included. Here, the cover 117 may be disposed above the first outdoor air inlet 112 to allow the inflow of the outside air.

The intake case 111 having a space formed therein may be disposed on one side of the blower unit 120 to communicate with the blower unit 120 . In this case, the intake case 111 may be disposed between the dash panel DP and the blower unit 120 , and may be disposed at the rear of the blower unit 120 based on the front-rear direction. Here, the rear may be a direction toward the interior 4 of the vehicle.

The first outdoor air inlet 112 and the second outdoor air inlet 113 may serve as passages through which outdoor air may be introduced into the intake case 111 .

The first outdoor air inlet 112 and the second outdoor air inlet 113 may be formed to be spaced apart from each other on the upper and lower sides of the intake case 111 . Accordingly, the intake unit 110 can more easily introduce outdoor air into the space through the two outdoor air inlets 112 and 113 that are vertically separated. In this case, the bet inlet 114 through which the bet is introduced may be formed on a side of the intake case 111 . Here, the first outdoor air inlet 112 may be referred to as an upper outdoor air inlet, and the second outdoor air inlet 113 may be referred to as a lower outdoor air inlet.

Accordingly, the intake unit 110 induces mixing of the outside air and the inside air through two outside air inlets 112 and 113 and one inside air inlet 114, so that the amount of air supplied to the air conditioning unit 200 is And the temperature can be variously adjusted. Here, the temperature of the outside and the inside may be different. For example, in summer, the temperature of the outside air may be higher than the temperature of the bet, and in winter, the temperature of the outside air may be lower than the temperature of the bet.

In addition, the size of the first outdoor air inlet 112 and the second outdoor air inlet 113 may be different. Accordingly, the amount of outdoor air introduced into the intake unit 110 through each of the first outdoor air inlet 112 and the second outdoor air inlet 113 may be different.

The first outdoor air inlet 112 serves as an inlet of outdoor air, and may be formed on the upper portion of the intake case 111 . In addition, the size of the first outdoor air inlet 112 may be larger than the size of the second outdoor air inlet 113 . Accordingly, the first outdoor air inlet 112 may serve as a main inlet for outdoor air. Here, the outdoor air introduced through the first outdoor air inlet 112 may be referred to as first outdoor air or upper outdoor air.

The second outdoor air inlet 113 serves as an inlet for outdoor air, and as shown in FIG. 4 , may be formed under the intake case 111 . In addition, the size of the second outdoor air inlet 113 may be smaller than the size of the first outdoor air inlet 112 . Accordingly, the second outdoor air inlet 113 may serve as a sub-inlet of outdoor air. Here, the outdoor air introduced through the second outdoor air inlet 113 may be referred to as second outdoor air or lower outdoor air.

The bet inlet 114 may be disposed to communicate with a hole formed in the dash panel DP. Accordingly, the bet inlet 114 can serve as an inlet through which the air of the vehicle interior 4 can be introduced.

Referring to FIGS. 3 and 5 , the bet inlet 114 may be formed on a side of the intake case 111 , and between the first outdoor air inlet 112 and the second outdoor air inlet 113 . can be placed.

That is, the bet inlet 114 may be formed at a position that facilitates mixing of the bet with respect to the first outdoor air and the second outdoor air. Therefore, the intake part 110 of the blower unit 100 limits the position of the bet inlet 114 in addition to the dividing wall 115 and the plurality of intake doors 116, thereby easily increasing the mixing ratio of the outside air and the bet. can be adjusted

The partition wall 115 may be disposed inside the intake case 111 to separate the flow of outdoor air introduced through each of the first outdoor air inlet 112 and the second outdoor air inlet 113 .

Accordingly, the intake unit 110 is separated from the first channel CH1 through which the first outside air flows inside the intake case 111 by the partition wall 115 and the first outside air. It may include a second channel CH2 through which the second external air flows. For example, the partition wall 115 may be horizontally disposed to divide an inner space of the intake case 111 into an upper portion and a lower portion. Accordingly, the first channel CH1 may be referred to as an upper intake channel, and the second channel CH2 may be referred to as a lower intake channel.

In addition, the partition wall 115 may be disposed to face or adjacent to the bet inlet 114 . For example, one end of the partition wall 115 may be disposed adjacent to the bet inlet 114 .

Here, the first intake door 116a may be referred to as a first dome door or an upper dome-type door.

Meanwhile, the first intake door 116a may adjust the opening amount of the first outdoor air inlet 112 and the indoor air inlet 114 . Accordingly, the first intake door 116a may control the amount of the first outside air and bet air to introduce the first outside air into the inside of the intake case 111 .

The second intake door 116b may control the opening or closing amount of the second outdoor air inlet 113 . In this case, the second intake door 116b may be disposed on the second channel CH2 . Accordingly, the second outdoor air introduced through the second outdoor air inlet 113 may move through the second channel CH2. Here, the second intake door 116b may be referred to as a second dome door or a lower dome-type door.

The third intake door 116c may be disposed on the inlet side of the second channel CH2 to open/close or adjust the opening amount of the inlet side of the second channel CH2 . Here, the inlet may refer to an area into which the bet is introduced based on the flow of air flowing through the second channel CH2.

Accordingly, the third intake door 116c enables the inflow or blocking of the bet in the second channel CH2.

In addition, the third intake door 116c may prevent the second outside air from flowing backward to the inside air inlet 114 side. For example, a second outdoor air inlet 113 is disposed in communication with the second channel CH2, and the third intake door 116c and the second Since the intake doors 116b are sequentially arranged (refer to FIG. 5 ), when the third intake door 116c closes the inlet side of the second channel CH2, the reverse flow of the second outside air can be prevented. . Accordingly, the second outdoor air flows only through the blower unit 120 .

Here, a plate-shaped flap door may be used as the third intake door 116c, and the third intake door 116c operates the second channel by a pressure difference without control by a separate driving device. The closed state of closing the inlet side of (CH2) can be maintained. Accordingly, it is possible to prevent the reverse flow of the second outside air.

The cover 117 may be disposed on the first outdoor air inlet 112 to enable the inflow of the outside air. Accordingly, the cover 117 may prevent the inflow of foreign substances falling into the intake case 111 through the first outdoor air inlet 112 .
