By installing the split case provided with the first frame and the second frame in the vehicle interior of the vehicle, the vehicle air that blows air outside the vehicle interior through the air passage in the split type case into the vehicle interior. A harmony device is configured.

When the air outside the vehicle compartment is sucked in, the water that has entered the air passage in the split mold case from the outside air suction port formed in the first frame is connected to the first fitting portion of the first frame. There is a possibility that it leaks out from between the second fitting portion of the second frame body. The water leaking from between the first fitting portion of the first frame and the second fitting portion of the second frame in this manner is an eave-like shape provided in the second fitting portion of the second frame. After falling along the guiding portion and falling into the gutter-shaped receiving portion provided in the first fitting portion of the first frame body and being received by the receiving portion, the outflow of water from the guiding portion and the receiving portion is prevented. Can be prevented.

[0011] This eliminates the need to attach a seal such as a bond or packing between the first fitting portion and the first fitted portion and between the second fitting portion and the second fitted portion. Even so, it is possible to prevent water from leaking into the vehicle interior from inside the split type case. For this reason, since the sealing operation is not required at the time of assembling the first frame, the second frame, and the intermediate frame, the assembling operation can be simplified. According to the third aspect of the present invention, the water falling along the eaves-shaped guiding portion into the gutter-shaped receiving portion and received by the receiving portion is formed by the first fitting portion of the first frame and the intermediate frame. The body is returned into the split mold case through the communication passage formed between the body and the first fitted portion.

[Operation of Embodiment] Next, the operation of the intake unit 1 of this embodiment will be briefly described with reference to FIGS.

When the electric motor 14 of the intake unit 1 is energized, the centrifugal fan 13 rotates. Then, the plurality of blades 17 scrape air on the inner peripheral side of the plate 16 toward the outer peripheral side. As a result, the air sucked into the air passage 9 of the split unit case 2 from the outside air suction port 21 or the inside air suction port 37 depending on the swing position of the inside / outside air switching door 3 is:
The air flows into the inner peripheral side of the centrifugal fan 13 through the bell mouth suction port 38, and is then blown out in the centrifugal direction of the centrifugal fan 13 and then blown into the vehicle compartment through the cooler unit and the heater unit.

Here, when the outside air introduction mode is selected as the suction port mode, the inside / outside air switching door 3 closes the inside air suction port 37 to fully open the outside air suction port 21. At this time, since the outside air suction port 21 is open, rainwater or water washing such as a car wash may enter the air passage 9 from the outside air suction port 21 through the outside air introduction passages 20 and 45 and the passage opening 46. is there.

The water remaining in the outside air introduction passage 20 is
Since the outside air inlet 21 is opened downward (in the vertical direction), the water is discharged again from the outside air inlet 21 to the outside of the vehicle compartment. It is easy to accumulate in the lower part of the upper case 6 (the side in the vertical direction in the vertical direction) and the intermediate cases 7, 8 (the side in the vertical direction in the vertical direction).

In this embodiment, the split unit case 2
Since no sealing material such as packing or bond is interposed between the joints of the split unit case 2, water accumulated in the split unit case 2 may leak from the joint of the split unit case 2. That is, as shown in FIGS. 1 and 5,
Between the fitting portion 22 of the lower case 5 and the fitting portions 33, 41 of the intermediate cases 7, 8, or the fitting portion 30 of the upper case 6.
There is a possibility of leaking to the outside of the split unit case 2 from between the fitting units 35 and 42 of the intermediate cases 7 and 8.

However, as shown in FIGS. 1 and 5, the ridges 23 of the fitting portion 22 of the lower case 5 and the fitting grooves 34, 43 of the fitting portions 33, 41 of the intermediate cases 7, 8. The water leaked from between the upper case 5 and the lower case 5 is received by the receiving tray 25 integrally formed on the upper end of the lower case 5. That is, the outflow of water to the outside of the gutter-like wall 24 of the lower case 5 (front of the vehicle interior) is prevented. Then, as shown in FIG. 6, the water received by the receiving pan 25 is
It is returned to the inside of the split unit case 2 through the plurality of communication passages 26 between 2 and 33.

Water leaking from between the fitting portion 30 of the upper case 6 and the fitting portions 35 and 42 of the intermediate cases 7 and 8 is, as shown in FIG. The guide 32 is integrally formed with the guide 32. That is, the outflow of water to the outside of the guide 32 of the upper case 6 (forward of the vehicle interior) is prevented. And Guide 3
The water received by the guide 2 is guided downward along the inner surface of the guide 32 and falls into the tray 25 as shown in FIG. As described above, the water that has fallen into the receiving tray 25 is returned into the split unit case 2 through the plurality of communication paths 26 between the adjacent fitting portions 22 and 33, as shown in FIG.

[Effects of Embodiment] As described above, the intake unit 1 of this embodiment is different from the split unit case 2
It is possible to prevent water from leaking from the inside of the split unit case 2 to the front of the vehicle compartment without attaching a sealing material such as a bond or packing to each joint. As a result, the lower case 5
The intermediate cases 7 and 8 are assembled to the
Since there is no need to perform a sealing operation at the time of assembling the split unit case 2 into which the upper case 6 is assembled, the assembling operation can be simplified.

Therefore, the work cost for assembling the split unit case 2 of the intake unit 1 can be reduced, and the product cost of the intake unit 1 can be reduced. For this reason, the price of the air conditioner for a vehicle including the inexpensive intake unit 1 can be reduced, and the price of the vehicle can be reduced.

In this embodiment, the protrusions 23 formed on the fitting portion 22 of the lower case 5 are partially provided, so that the fitting portion 22 of the lower case 5 and the intermediate case 7 can be fitted. Since a plurality of communication passages 26 are formed between the joint portion 33 and the water, the water received by the tray 25 can easily return into the split unit case 2, and the water received by the tray 25 can flow through the gutter-shaped wall 2.
4 can be prevented from leaking out of the gutter-like wall 24 (to the front in the vehicle compartment).

[Modification] In this embodiment, the fitting portions 22, 30 having the ridges 23, 31 are provided as male fitting portions. A fitting portion having a triangular or circular ridge may be provided. In this embodiment, the fitting grooves 34, 43,
