TECHNICAL FIELD

The present invention relates generally to aeration devices intended to diffuse, in the passenger compartment of a motor vehicle, air coming from a heating, ventilation and air conditioning system of said vehicle.

BACKGROUND

Such an aeration device, known for example from French patent application FR 2,956,065, conventionally includes at least one aerator comprising a channel delimited by a hollow body and able to convey an air flow to an outlet opening emerging in the passenger compartment of the vehicle, as well as at least one deflector fin mounted rotating in this channel near the outlet opening. The aerator also comprises an actuator mechanically connected to this or these fin(s) and allowing the user to control the rotation thereof so as to orient the flow of air leaving the body.

A concealing flap controllable by a dedicated control mechanism is further generally mounted pivoting in the duct upstream from this or these fin(s) between a maximum open position and a closed position preventing the conveyed air flow from escaping through the outlet opening.

These aerators, which generally emerge on the dashboard of the vehicle, are unattractive and negatively affect the quality level perceived by the users.

In order to address these drawbacks, U.S. Pat. Application Publication No. 2014/0357179 describes an aeration device implementing the physics phenomenon known as the “Coanda” effect, according to which a flow guided while attaching itself to curved surfaces has a low head loss and thus generates little noise.

It has the advantage of being particularly attractive (only the end of the core remain visible to users, while the other mechanical elements are in turn hidden), which makes it possible to significantly improve the perceived quality level of the entire dashboard of the vehicle.

The control of such an aeration device is conventionally provided by means of a control module integrated into the center console of the vehicle. Such a module, described for example in international patent application publication WO 00/21765, comprises a plurality of control means making it possible to adjust certain parameters, such as the ventilation air flow rate leaving the aerator and the setpoint temperature for the zone of the passenger compartment treated by this aerator.

These control modules nevertheless have the drawback of being cumbersome, in particular in terms of the center console of the vehicle, where they considerably reduce the available space.

SUMMARY

The present invention therefore aims to improve the situation.

To that end, there is provided an aeration device for the heating, ventilation and air conditioning system for a motor vehicle, including at least one aerator, comprising:

a channel capable of conveying an air flow from an inlet opening to an outlet opening emerging in an enclosure;

a hollow air guiding core housed in said channel and defining two air guiding surfaces opposite one another, said two guiding surfaces and said channel thus delimiting two flow paths capable of transporting, respectively, to said outlet opening, first and second quantities of air coming from said inlet opening;

a first fin mounted pivoting upstream from said guiding core and arranged so as to make it possible to adjust, as a function of its position, the ratio between the first and second quantities of air;

characterized in that said aeration device includes a control module integrated at least partially into the guiding core of at least said aerator, said control module comprising a control panel constituted at least partially by a downstream end wall of said guiding core and being equipped with a control device making it possible to control the heating, ventilation and air conditioning system.

By at least partially integrating the control module of the heating, ventilation and air conditioning system into the guiding core of one or several aerators, the aeration device makes it possible, without affecting the passage section of the air flow delivered into the passenger compartment by this or these aerators, to free space, in particular at the center console of the vehicle, for example to install zones therein for accommodating roaming devices or for additional storage.

According to preferred features of said aeration device:

said control device includes at least one pushbutton and an adjusting ring mounted rotating around said pushbutton;

said control device includes at least one slidable knob;

said control device includes at least one touch-sensitive zone control device;

said control panel includes at least one display zone provided with one or several lighted indicators each displaying the selected value of one of the adjustment parameters of said heating, ventilation and air conditioning system;

said control module includes a control device making it possible to control other functional devices of said vehicle;

the at least said aerator includes rows of second parallel deflector fins mounted pivoting in said channel along axes of rotation perpendicular to that of said first fin and secured in rotation via connecting means connecting them to one another;

said aeration device includes two said aerators arranged side by side and separated by a partition and intended to diffuse air in the passenger compartment of the motor vehicle, respectively on the driver's side and on the front passenger's side;

said panel extends continuously between the two said aerators; and/or

According to a second aspect, the invention also relates to a motor vehicle including one such aeration device.
