    COMPACT VENTILATION DEVICE WITH COANDA EFFECT FOR A MOTOR VEHICLE INCLUDING A CONTROL MODULE PROVIDED WITH A CONTROL PANEL.
    Field of the invention
    The present invention relates generally to ventilation devices intended to diffuse in the passenger compartment of a motor vehicle air coming from the heating, ventilation and air conditioning system of said vehicle.
    Invention background
    Such an aeration device, known for example from French patent application FR 2 956 065, conventionally comprises at least one aerator comprising a channel delimited by a hollow body and capable of channeling a flow of air up to an opening of outlet opening into the passenger compartment of the vehicle, as well as at least one deflection fin rotatably mounted in this channel near the outlet opening. The aerator also includes an actuator mechanically connected to this or these fins and allowing the user to control its rotation in order to orient the air flow leaving the body.
    A concealment flap controllable by a dedicated control mechanism is also generally pivotally mounted in the duct upstream of this or these fins between a maximum open position and a closed position preventing the flow of air ducted from s escape through the outlet opening.
    These aerators which generally lead to the dashboard of the vehicle are unsightly and negatively impact the level of quality perceived by users.
    In order to overcome these drawbacks, American patent application 2014/0357179 describes an aeration device implementing the physical phenomenon known as the "Coanda effect" according to which a guided flow by attaching to curved surfaces nrpçpntp iinp faihlp nprfp dp rharnp pf πρπργρ ainçi πριι dp hmit
    It has the advantage of being particularly aesthetic (only the end of the core remaining visible to users while the other mechanical elements are concealed) which allows to significantly improve the level of perceived quality of all the vehicle dashboard.
    The piloting of such a ventilation device is conventionally ensured by means of a control module integrated in the central console of the vehicle. Such a module, described for example in international application WO 00/21765, comprises a plurality of control means making it possible to adjust certain parameters such as the flow rate of ventilation air leaving the aerator and the set temperature for the zone of the passenger compartment treated by this aerator.
    However, these control modules have the disadvantage of being bulky, especially at the level of the central console of the vehicle where they considerably reduce the space available.
    Subject and summary of the invention
    The present invention therefore aims to improve the situation.
    To this end, it proposes an aeration device for a heating, ventilation and air conditioning system of a motor vehicle, comprising at least one aerator comprising: - a channel capable of channeling an air flow from an opening of entry to an exit opening leading to an enclosure; - a hollow air guide core housed in said channel and defining two air guide surfaces opposite one another, the two said guide surfaces and said channel thus delimiting two flow paths adapted to transport respectively to said outlet opening a first and a second quantity of air coming from said inlet opening; - A first fin pivotally mounted upstream of said guide core and arranged so as to allow to adjust according to its position the ratio between the first and second quantities of air; characterized in that said aeration device comprises a control module integrated at least partially in the guide core of the at least said aerator, said control module comprising a control panel formed at least partially by a downstream end wall of said guide core and being provided with control means making it possible to control said heating, ventilation and air conditioning system.
    By integrating at least partially the control module of the heating, ventilation and air conditioning system in the guide core of one or more aerators, the aeration device according to the invention allows, without impacting the flow passage section the air delivered into the passenger compartment by this or these aerators, to free up space, in particular at the level of the central console of the vehicle in order to install, for example, reception areas for mobile devices or additional storage.
    According to preferred characteristics of said ventilation device according to the invention: - said control means comprise at least one push button and an adjustment ring rotatably mounted around said push button; - Said control means comprise at least one sliding mounted slider; - Said control means comprise at least one touch control zone; - Said control panel comprises at least one display zone provided with one or more light indicators each displaying the selected value of one of the adjustment parameters of said heating, ventilation and air conditioning system; - Said control module comprises control means making it possible to control other functional devices of said vehicle; - The at least said aerator comprises a row of second parallel deflection fins pivotally mounted in said channel ςρΙηη rlpç aypç rlp rntatinn nprnpnriinilairpç to γρΙιιϊ rlp larlitp nrpmièrp fin and being integral in rotation by means of connecting means connecting them; - Said ventilation device comprises two said aerators arranged side by side being separated by a partition and being intended to diffuse air in the passenger compartment of the motor vehicle, respectively on the driver side and on the front passenger side; - Said facade extends continuously between the two said aerators; and / or The invention also relates, in a second aspect, to a motor vehicle comprising such a ventilation device.
    Brief description of the drawings The description of the invention will now be continued with the detailed description of an exemplary embodiment, given below by way of illustration but not limitation, with reference to the accompanying drawings, in which: - Figure 1 shows a perspective view of a ventilation device for a motor vehicle according to the invention; - Figure 2 is a perspective sectional view of the ventilation device of Figure 1 taken along an axial vertical plane; - Figure 3 shows a sectional view of the ventilation device of Figure 1 taken along an axial vertical plane located at the slider for adjusting the orientation of the fins of the aerator of the front passenger; - Figure 4 is a sectional view of the aeration device of Figure 1 taken along an axial vertical plane located at a push button control of the control module of the heating, ventilation and air conditioning system.
    Detailed description of a preferred embodiment The ventilation device 1 shown in the figures is intended to be installed in the central part of the dashboard (not shown) of a motor vehicle in order to diffuse into the passenger compartment of this conveys the forced air from the heating, ventilation and air conditioning (HVAC) system of this vehicle.
    As illustrated in FIG. 1, the ventilation device 1 comprises a hollow body 2 housing two similar aerators 3, 4 arranged side by side, being separated by a partition 2A and being intended to diffuse air in the passenger compartment of the motor vehicle, respectively on the driver side and on the front passenger side.
    Each aerator 3, 4 comprises a channel 10 delimited by the body 2 and capable of channeling an air flow F from an inlet opening 11 to an outlet opening 12 opening into the passenger compartment of the vehicle (FIG. 2) .
    In the remainder of this description, the terms “upstream” and “downstream” used to characterize the position of certain elements of the aeration device 1 will have to be considered with respect to the direction of circulation of the air flow F in the channels 10.
    As illustrated in FIG. 3, each channel 10 successively comprises, from the inlet opening 11 towards the outlet opening 12, an upstream section 10A, an intermediate section 10B and a downstream section 10C.
    The upstream section 10A has a constant rectangular cross section over its entire length.
    The intermediate section 10B has a section which widens in the direction of circulation of the air flow F in the channel 10, while that of the downstream section 10C narrows in the direction of circulation of the air flow F.
    Each aerator 3, 4 also comprises a hollow air guide core 13 preferably having a substantially ovoid section and being housed in the intermediate 10B and downstream 10C sections of a corresponding channel 10, being advantageously rigidly connected with the latter.
    Each core 13 defines a first air guide surface 14 and a second air guide surface 15 extending symmetrically opposite one another with respect to the median horizontal plane of the channel 1D rnrrpçnnnriant
    The upper and lower portions of the sections 10B, 10C of each channel 10 located respectively opposite the first and second guide surfaces 14, 15 extend parallel to the latter so as to delimit two upper 16 and lower 17 flow paths of section substantially constant and symmetrical with respect to the median horizontal plane of channel 10.
    These channels 16 and 17 are capable of transporting, respectively to the outlet opening 12, a first and a second quantity of air coming from the inlet opening 11.
    Each aerator 3, 4 also comprises a rectangular deflection fin 18 pivotally mounted in the upstream section of the channel 10 near the guide core 13 and along a horizontal transverse axis of rotation A.
    This fin 18 is arranged so as to allow, by varying its inclination, to adjust the ratio between the first and second quantities of air and therefore the direction of exit of the air flow F relative to the horizontal.
    Thus, when the fin 18 occupies its extreme upper position illustrated in FIG. 3, the upper flow path 16 is closed. The entire air flow F then circulates in the lower flow path 17 and leaves the outlet opening 12 while being directed upwards.
    Conversely, when the fin 18 occupies its extreme low position, the lower flow path 17 is closed. The entire air flow F then circulates in the upper flow path 16 and leaves the outlet opening 12 while being directed downwards.
    When the fin 18 extends horizontally in a position located halfway between these two extreme high and extreme low positions (see FIG. 4), the same quantity of air circulates in the two upper flow paths 16 and lower 17 so that at the outlet the air flow F is directed substantially horizontally.
    In order to obtain an almost perfect seal and avoid the emission of unpleasant hissing in the passenger compartment of the vehicle when it comes nrmnpr nnçitinn pytrÂmp haiitp nu pytrpmp haçç rhamip ailpttp 18 is provided with an elastically deformable lip 19 made of material elastomer molded at its upstream end.
    As illustrated in FIGS. 2 and 3, each aerator 3, 4 further comprises a row of parallel vertical deflection fins 20 pivotally mounted in the upstream 10A and intermediate 10B sections of the channel 10 along parallel vertical axes B, and being integral in rotation by means of a connecting rod 21 connecting them together.
    These vertical fins 20 have an upstream portion provided with a central notch 22 in V crossed by the downstream portion of the fin 18 and whose dimensions are adapted so as not to disturb the pivoting of this fin, as well as a downstream portion formed two curved arms 23, 24 housed in the two flow paths 16, 17 and whose profiles correspond substantially to the curved profiles of these paths.
    The variation in the inclination of these vertical fins 20 thus makes it possible to adjust the direction of exit of the air flow F relative to the median vertical plane of the ventilation device 1.
    The pivoting movement of the vertical fins 20 of each aerator 3, 4 is ensured by means of a respective control mechanism 25 located near its outer end.
    Each of the control mechanisms 25 comprises an arm 26 housed in the guide core 13 of the corresponding aerator 3, 4 the downstream end of which is mounted in translation along a horizontal transverse axis C and pivoting around this same axis C.
    This downstream end of the arm 26 is extended by a slider 27 projecting from the external portion of the vertical flat wall 13A forming the beveled downstream end of the core 13 and allowing the user to actuate this arm 26 in translation and in pivoting ( see Figures 1 and 2). The upstream end of the arm 26 carries a guide finger 28 extending transversely and being mechanically coupled with a fork 29 rigidly connected to a corresponding fin 18 and ç'ptpnrlant rlanç ςηη nrnlnnnpmpnt down dp çnrtp πιιρ Ip nivntpmpnt vprç top or towards the bottom of the slider 27 causes that of this fin 18 in the same direction (FIG. 3).
    Each control mechanism 25 also includes a link (not visible in the figures) hingedly connecting the slider 27 to the vertical fins 20 of the corresponding aerator 3, 4, so that the translation of this slider 27 in one direction causes via this rod pivoting in the same direction of the vertical fins 20.
    As illustrated in FIGS. 3 and 4, each aerator 3, 4 further comprises a respective concealment flap 30 pivotally mounted in the upstream section of the corresponding channel 10 upstream of the deflection fin 18 and along a transverse axis. horizontal rotation D.
    Each flap 30 can be controlled by a dedicated control mechanism which can be actuated by a respective wheel 31 partially projecting from a corresponding lateral portion of the peripheral window 2B bordering the downstream end of the hollow body 2 (see FIGS. 1 and 2), between a position horizontal maximum opening and a vertical closed position completely closing the channel 10 so as to prevent the ducted air flow F from escaping through the outlet opening 12.
    In order to obtain an almost perfect seal and avoid the emission of unpleasant hissing in the passenger compartment of the vehicle when it comes to occupy its closed position, each blocking flap 30 is provided with two elastically deformable lips 32 in elastomeric material overmolded at both ends.
    As shown in Figure 1 and in order to ensure continuity of appearance between the visible downstream parts of the two hollow guide cores 13, the latter are connected to each other by a central hollow connecting element 33 of identical section.
    According to the invention and as illustrated in FIG. 1, the ventilation device 1 comprises a control module 40 for the heating, ventilation and air conditioning (HVAC) system of the vehicle, integrated in the two hollow guide cores 13 and in the central connecting element 33.
    This control module 40 comprises a control panel 41 extending transversely continuously between the two aerators 3, 4 (more precisely between the two sliders 27 of the latter) and being constituted by the three downstream end walls 13A, 33A of the two hollow guide cores 13 and of the central connecting element 33.
    The device 40 also includes an electronic printed circuit board (PCB) 42 as well as at least one light box 43 housed in the two hollow guide cores 13 and the central connecting element 33, the light box or boxes 43 being interposed between the internal face of the control panel 41 and the electronic card 42.
    As illustrated in FIG. 1, the control panel 41 which constitutes the visible and accessible part of the control module 40, is provided with control means comprising three push buttons 44, 45, 46 as well as three adjustment rings 47, 48, 49 mounted rotary around the latter.
    The first push button 44, located near the cursor 27 of the aerator 3, allows the user to activate or deactivate the automatic operating mode of the HVAC system.
    The second push button 45, located near the cursor 27 of the aerator 4, allows the user to activate or deactivate the air conditioning.
    The third push button 46, located at the median vertical plane of the facade 41, allows the user to activate or deactivate the HVAC system.
    The first rotary ring 47 surrounding the push button 44 allows the user to adjust the setpoint temperature on the driver's side.
    The second rotary ring 48 surrounding the push button 45 allows the user to adjust the set temperature on the front passenger side.
    The third rotary ring 49 surrounding the push button 46 allows the user to adjust the air flow of the HVAC system.
    The control panel 41 is advantageously made of a black smoke-colored transparent thermoplastic material, such as polycarbonate (PC) or polymethyl methacrylate (PMMA), the latter offering the advantage of having excellent transparency and being not very sensitive scratched.
    This facade 41 also incorporates several display zones 50, 53 each formed between two pairs of buttons / rings and being provided with one or more light indicators 51, 52, 53 each displaying the selected value of a system adjustment parameter CVC.
