1 is a configuration diagram showing a vehicle ventilation system according to the present invention, Figures 2a and 2b is a state diagram showing the operation of the air vent hall screen in the present invention.

The present invention relates to a vehicle ventilation system with a humidity control function, as shown in FIG. 1, an air blow passage 20 to supply air sent from an air conditioner (not shown) to a vehicle interior. Is provided, and the air flowing through the blow passage 20 is discharged to a predetermined position in the vehicle interior through the air vent hole 30, and the air vent hole 30 has a large number of crash pads, center fascia, etc. Dogs may be provided.

In the ventilation system of the present invention, the humidity control device 40 is provided to achieve humidity control of the vehicle interior. The water spray generated by the humidity control device 40 is discharged to the vehicle interior together with the air to dry the vehicle interior. It is humidified.

First, the opening and closing structure of the air vent hole in the ventilation system of the present invention will be described.

2A and 2B, a plurality of air vent hole screens 34 are disposed radially and inserted around the air vent hole 30, as shown in FIGS. 2A and 2B. The sliding movement of the radial direction in the groove 32 is installed to bar, each air vent hole screen 34 is made to enter and exit independently of the insertion groove (32).

The air vent hole screen 34 closes the air vent hole 30 while slidingly moving radially toward the central spray generator 43 which will be described later, and is inserted into the insertion groove 32 while the air vent hole is inserted. Open 30.

Accordingly, the air vent hole screen 34 may allow the operator to selectively open or close any one or part of the plurality of air vent hole screens 34, and the spray generator when the air vent hole 30 is completely closed. Except for 43, the entire area of the air vent hole 30 is sealed.

Here, the tip end of the air vent hole screen 34 is inserted into the sealing groove 42a formed on the outer surface of the spray generating part 43 in the center.

In addition, as shown in FIG. 2B, each of the air vent hole screens 34 has a magnetic plate 36 attached to one side end thereof, and a magnetic plate of the air vent hole screen 34 adjacent to the other side end thereof. To the 36 is attached a steel plate 38 which can be magnetically attached.

Therefore, when the adjacent air vent hole screen 34 completely closes the air vent hole 30, the airtight between the two air vent hole screens 34 is attached to the magnetic plate 36 and the steel plate 38. Will be maintained.

As a result, when all the air vent hole screens 34 are closing the air vent hole 30, the tip is inserted into the sealing groove 42a, and at the same time, mutual airtight between the air vent hole screens 34 adjacent to each other is maintained. The entire area of the air vent hole 30 except for the spray generator 43 may be completely sealed.

In particular, the air vent hole screen 34 is protruded in a direction inclined to a certain degree toward the front which is the discharge direction of the air (arrow 'A' in FIG. 1), so that only a part of the air vent hole screen selectively controls the discharge direction of the air. It becomes possible.

In addition, for convenience when opening or closing the air vent hole screen 34, preferably, the front surface of the air vent hole screen 34 is provided with a protruding handle 39, the handle 39 is The air vent hole screen 34 also serves as a stopper to prevent the insertion groove 32 is completely inserted.

Next, as shown in FIG. 1, the humidity control device 40 includes a water tank 41 capable of replenishing water, a spray generator 43 for generating water spray in the air vent hole 30, and A water supply tube 47 connecting the water tank 41 and the spray generator 43, a solenoid valve 48 to selectively open and close the water supply tube 47, and the solenoid valve ( 48) an operating switch 49 for opening and closing operation.

The spray generator 43 is supported by the support bar 42 in the center of the air vent hole 30 is installed long in the flow direction of air, the water supplied through the water supply tube 47 is filled Is provided with a water receiving portion 44, the air passage 45 is to pass through the water receiving portion 44 in the longitudinal direction to allow the air to pass through.

Here, the inner space in which the water is filled, that is, the water receiving portion 44 has a form surrounding the air passage 45, a plurality of fine spray holes 46 in the inner surface of the air passage 45 Formed.

That is, the spray hole 46 is formed in the wall separating the water receiving portion 44 and the air passage 45, the water of the water receiving portion 44 through the spray hole 46 through the air passage ( 45) it is sprayed inside.

Referring to the principle that water is sprayed through the spray hole 46 as described above are as follows.

In order to operate the humidity control device 40 of the present invention, all the air vent hole screens 34 are closed. As such, when the entire area of the air vent hole 30 except for the spray generator 43 is closed, a ventilation passage ( Air supplied through 20 is rapidly flowed while passing through the air passage 45 of the spray generator 43 having a small diameter.

Therefore, a negative pressure is generated around the spray hole 46 of the air passage 45, and the water in the water accommodating portion 44 is ejected into the air passage 45 through the spray hole 46 in the form of a spray by the negative pressure. will be.

In this way, in order to operate the humidity control apparatus 40 of the vehicle ventilation system according to the present invention, first, all the air vent hole screens 34 are closed to remove the air vent hole 30 except the spray generator 43. The entire area of the valve is sealed, and the operation switch 49 of the solenoid valve is turned on to open the water supply tube 47.

Thereafter, water is sprayed into the air passage 45 due to the air passing through the air passage 45 while the water is supplied from the water tank 41 to the water receiving portion 44 of the spray generator 43. In addition, the water spray is discharged into the vehicle interior together with the air passing through to humidify the indoor air.

In addition, when the humidity control device 40 is turned off, only the selected air vent hole screen 34 is opened to adjust the wind direction of the air.

As described above, according to the vehicle ventilating system according to the present invention, by providing a humidity control device including a spray generator, it is possible to prevent the drying of the vehicle interior, to maintain a comfortable indoor environment, safety There is an effect that can contribute to driving.

In addition, by providing an air vent hole screen that can be opened and closed independently, it is possible to simplify the opening and closing structure of the air vent hole while being able to adjust the wind direction, and only the air vent hole screen of the desired position needs to be adjusted together with two wind direction control levers Operation convenience can be improved in comparison with the prior art.
