    104 / AERATOR FOR A MOTOR VEHICLE WITH IMPROVED COMPACTION.

    AERATOR. FOR A MOTOR VEHICLE WITH IMPROVED COMPACTION.
    Field of the invention
    The present invention relates generally to aerators intended to diffuse air in a passenger compartment of a motor vehicle.
    Invention background
    Such an aerator, known for example from French patent application FR 2 956 065, conventionally comprises a hollow body capable of channeling a flow of air to an outlet opening opening into the passenger compartment of the vehicle, as well as to the minus a deflection fin rotatably mounted in this body near the outlet opening. The device 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 proposes an aerator comprising:
    - A hollow body capable of channeling an air flow from an inlet opening to an outlet opening leading to an enclosure;
    - a hollow air guide core with an egg-shaped section rigidly housed in the hollow body and defining two air guide surfaces opposite one another, the two guide surfaces and the hollow body thus delimiting two flow channels able to transport respectively to the outlet opening a first and a second quantity of air coming from the inlet opening; and
    - A fin pivotally mounted upstream of the guide core and arranged so as to allow the ratio between the first and second quantities of air to be adjusted as a function of its position.
    Thus, according to the value of this ratio, the direction of the air flow leaving the aerator and perceived by the users will be modified. When the two quantities of air are identical, the outgoing air flow extends in a direction parallel to the axis of the duct.
    Such an aerator implements the physical phenomenon known as the "Coanda" effect according to which a guided flow by attaching to curved surfaces has a low pressure drop and thus generates little noise.
    However, it has the drawback of being considerably longer than a conventional aerator, which makes it difficult and sometimes impossible to incorporate upstream concealment means, so that in practice this type of aerator is installed only on some references of dashboards offering enough space.
    Subject and summary of the invention
    The present invention therefore aims to improve the compactness of this type of aerator.
    To this end, it provides an aerator for a motor vehicle comprising a hollow body capable of channeling a flow of air from an inlet opening to an outlet opening opening onto an enclosure, a hollow core for guiding air to egg-shaped section rigidly housed in said hollow body and defining two air guide surfaces opposite each other, the two said guide surfaces and said hollow body thus delimiting two flow channels adapted to transport respectively to said outlet opening a first and a second quantity of air coming from said inlet opening;
    characterized in that it comprises two first fins pivotally mounted upstream of said guide core along the same axis of rotation and arranged so as to be able to adopt a first deflection configuration in which they are joined against one another to form a single wing whose variation in inclination makes it possible to adjust the ratio between said first and second quantities of air and therefore the direction of exit of said air flow, as well as a second closing configuration in which said fins are spaced from each other so as to completely obstruct said hollow body upstream of said core and prevent said air flow from escaping through said outlet opening.
    The first two fins of the aerator according to the invention thus constitute not only means for deflecting the air flow but also means for obscuring the hollow body so that it is not necessary to provide upstream of these a specific blackout shutter.
    The aerator according to the invention is therefore much more compact than current aerators with a "Coanda" effect and can therefore be installed on almost all dashboards of motor vehicles.
    According to preferred characteristics of said aerator according to the invention:
    - in said deflection configuration, said wing is able to be moved between a first extreme position in which a first of said flow channels is closed so that all of said air flow circulates in the second of said flow channels, and a second extreme position where the second of said flow channels is closed so that all of said air flow circulates in the first of said flow channels,
    - Said first fins are each provided at their upstream end with an elastically deformable sealing lip;
    - Said aerator further comprises a row of second parallel deflection fins pivotally mounted in said body along axes of rotation perpendicular to that of said first fins and being integral in rotation by means of connecting means connecting them together;
    - Said second fins have an upstream portion provided with a central notch traversed by the downstream portions of said first fins and the dimensions of which are adapted so as not to disturb the pivoting of the latter;
    - Said second fins have a downstream portion formed by two curved arms housed in the two said flow channels;
    - The pivoting movement of said first and second fins is ensured by means of a control mechanism housed in said guide core;
    - Said control mechanism comprises a guide profile rigidly connected to an actuator by a connecting arm, said profile comprising two guide branches extending on either side of said arm and being mechanically coupled with two respective forks each rigidly linked to a said first corresponding fin;
    - Said control mechanism comprises a link hingedly connecting an actuator to one of said second fins; and or
    - Said control mechanism is controlled by a single protruding actuator of said body downstream of said outlet opening, said actuator being mounted movable in translation and pivoting respectively along and around an axis parallel to the axis of rotation of said first fins.
    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 appended drawings, in which:
    - Figure 1 shows a vertical vertical sectional view of an aerator according to the invention in which the fins occupy their deflection configuration in which they are joined against one another;
    - Figure 2 is a view similar to Figure 1 but in which the fins occupy their closed configuration in which they are spaced from one another so as to completely obstruct the hollow body upstream of the core;
    - Figure 3 shows a perspective view of the aerator whose fins occupy their deflection configuration and on which the hollow body and the guide core have been omitted in order to facilitate understanding; and
    - Figure 4 is a view similar to Figure 3 showing the fins in their closed configuration.
    Detailed description of two preferred embodiments The aerator 1 shown in FIG. 1 is intended to be installed in the dashboard (not shown) of a motor vehicle in order to diffuse in the passenger compartment of this vehicle the forced air from a ventilation and / or air conditioning system.
    As illustrated in this FIG. 1, the aerator 1 comprises a hollow body 2 able to channel an air flow F from an inlet opening 3 to an outlet opening 4 opening into the passenger compartment of the vehicle.
    In the rest of this description, the terms “upstream” and “downstream” used to characterize the position of certain elements of the aerator 1 are to be considered with respect to the direction of circulation of the air flow F in the hollow body 2.
    The hollow body 2 consists successively, from the inlet opening to the outlet opening, of an upstream section 2A, of an intermediate section 2B and of a downstream section 2C.
    The upstream section 2A has a constant rectangular cross section over its entire length.
    The intermediate section 2B has a section which widens in the direction of circulation of the air flow F in the hollow body 2, while that of the downstream section 2C narrows in the direction of circulation of the air flow F.
    The aerator 1 also includes a hollow air guide core 5 with an egg-shaped section rigidly housed in the intermediate 2B and downstream 2C sections of the hollow body 2.
    This core 5 defines a first air guide surface 6 and a second guide surface 7 extending symmetrically opposite one another relative to the median plane of the hollow body 2.
    The upper and lower portions of the sections 2B, 2C of the hollow body 2 located respectively opposite the first and second guide surfaces 6, 7 extend parallel to the latter so as to delimit two upper flow channels 8 and lower 9 of section substantially constant and symmetrical with respect to the horizontal median plane of the hollow body 2.
    These channels 8 and 9 are capable of transporting, respectively to the outlet opening 4, a first and a second quantity of air coming from the inlet opening 3.
    Two rectangular fins 10A, 10B are also pivotally mounted in the upstream section of the body 2 near the guide core 5 and along the same horizontal transverse axis of rotation A.
    These two fins 10A, 10B are arranged so as to be able to adopt a first deflection configuration (FIG. 1) in which they are joined against one another to form a single wing 10 whose variation in inclination makes it possible 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.
    In this configuration, when the wing 10 occupies its extreme high position illustrated by this FIG. 1, the upper flow channel 8 is closed. The entire air flow F then circulates in the lower flow channel 9 and leaves the outlet opening 4, being directed upwards.
    Conversely, when the wing 10 occupies its extreme low position, the lower flow channel 9 is closed. The entire air flow F then circulates in the upper flow channel 8 and leaves the outlet opening 4 while being directed downwards.
    When the wing 10 extends horizontally in a position situated halfway between these two extreme high and extreme low positions, the same quantity of air circulates in the two upper 8 and lower 9 flow channels so that at the outlet, the air flow F is directed substantially horizontally.
    The two fins 10A, 10B are also capable of coming to occupy a second closing configuration (FIG. 2) in which the latter are separated from one another so as to completely obstruct the section 2A of the hollow body 2 upstream of the core 5 and prevent the air flow F from escaping through the outlet opening 4.
    In order to obtain an almost perfect seal and avoid the emission of unpleasant hissing in the passenger compartment of the vehicle in the closed configuration, the fins 10A, 10B are each provided with an elastically deformable lip 11 made of elastomeric material overmolded to their upstream end.
    The aerator 1 further comprises a row of five parallel deflection fins 12A, 12B, 12C, 12D, 12E pivotally mounted in the upstream 2A and intermediate 2B sections of the body 2 along vertical axes Bl, B2, B3, B4, B5 and integral in rotation by means of a connecting rod 13 connecting them together.
    As can be seen in the figures, these fins 12A, 12B, 12C, 12D, 12E have an upstream portion provided with a central notch 15 in V crossed by the downstream portions of the fins 10A, 10B and whose dimensions are adapted for do not disturb the pivoting of these two fins, as well as a downstream portion formed by two curved arms 16, 17 housed in the two flow channels 8, 9 and whose profiles correspond substantially to the curved profiles of these channels.
    The variation in the inclination of these fins 12A, 12B, 12C, 12D, 12E thus makes it possible to adjust the direction of exit of the air flow F relative to the median vertical plane of the aerator 1.
    The pivoting movement of the fins 10A, 10B, 12A, 12B, 12C, 12D, 12E is ensured by means of a control mechanism controlled by a single actuator 18 which can be translated horizontally along a horizontal transverse axis C and rotated vertically with respect to this axis C.
    The actuator consists of a slider 18 projecting from the body 2 downstream of the outlet opening 4 so as to be easy to handle by the user.
    The control mechanism housed in the guide core 5 comprises a guide profile 20 rigidly connected to the cursor 18 via a link arm 19 and extending along a plane perpendicular to this cursor 18.
    The profile 20 consists of two guide branches 21, 22 extending on either side of the link arm 19 and being mechanically coupled with two respective forks 23, 24 each rigidly linked to a corresponding fin 10A, 10B and s 'extending in its downstream extension (Figures 3 and 4).
    The first guide branch 21 coupled to the fork 23 successively comprises, from the connecting arm 19, a first horizontal section 21A, a section inclined along an ascending slope 21B, a second horizontal section 21C and a vertical section 21D forming its lateral end external.
    In order to improve its rigidity, this first branch 21 further comprises two holding sections 21E, 21F connecting the vertical end section 21D to the connecting arm 19.
    The second guide branch 22 coupled to the fork 24 successively comprises, from the connecting arm 19, a first horizontal section 22A of the same length as the section 21C and visible in dotted lines in FIGS. 3 and 4, an inclined section 22B likewise length as the section 21B and of opposite slope, a second horizontal section 22C coaxial with the section 21A and of the same length, and a vertical section 22D forming its external lateral end and of the same length as the section 21D.
    In order to improve its rigidity, this second branch 22 further comprises two holding sections 22E, 22F connecting the vertical end section 22D to the connecting arm 19.
    The coupling mechanism also includes a link 25 hingedly connecting the slider 18 to the central vertical fin 12C. More precisely, the downstream end of this bar 25 is pivotally articulated with the slider 18 around its horizontal transverse axis of rotation C, while its upstream end is pivotally articulated with the fin 12C around a vertical axis D (Figures 3 and 4).
    In the central lateral position of the slider 18 illustrated in FIGS. 1 and 3, the two forks 23, 24 guided by the coaxial horizontal sections 21A and 22C are coplanar so that the two fins 10A, 10B adopt their deflection configuration where they are joined against each other to form a single wing 10. The pivoting up or down of the cursor 18 then causes that of the wing 10 in the same direction.
    From this position, the translation of the cursor 18 to the left causes via the link 25 the pivoting in the same direction of the vertical fins 12A, 12B, 12C, 12D, 12E. The forks 23, 24 remaining guided by the horizontal coaxial sections 21A and 22C, the fins 10A, 10B always forming a single wing 10 orientable by the pivoting up or down of the cursor 18.
    This translation to the left of the cursor 18 (and therefore the pivoting of the vertical fins) can be continued until the two forks 23, 24 abut respectively against the arm 19 and the vertical section 22D.
    When the cursor 18 is translated to the right from its central lateral position in FIGS. 1 and 3, the forks become guided by the inclined sections 21B, 22B. These sections having opposite slopes, the forks 23, 24 are pivotally driven in opposite directions so that the fins 10A, 10B gradually move away from each other until they come to occupy their closed configuration in which they obstruct the upstream section 2A of the body 2 and where the cursor 18 is prevented from pivoting.
    By continuing this movement of translation of the cursor 18 to the maximum to the right, the latter can be brought to the stable position illustrated in FIGS. 2 and 4 in which the two forks
    23, 24 are in abutment respectively against the vertical section 22D and the arm 19 while being guided by the horizontal sections 21C, 22A so as to avoid any approach between the two fins 10A, 10B due to the elastic restoring forces exerted by the two end lips 11 against the internal face of the body 2 when these fins occupy their closed configuration.
    According to variant embodiments not shown, the vertical fins are absent or their number is different (for example equal to 2, 3 or 4).
    According to yet other alternative embodiments of the invention, the means for controlling the orientation of the vertical fins are dissociated from those of the fins 10A, 10B.
    Of course, the present invention is not limited to the embodiments described and shown, but also encompasses all the variant embodiments within the reach of the skilled person.
    It will be noted in particular that the aerator can also be installed in different places of a motor vehicle such as the roof or roof light, a central console arranged between two seats, a central leg separating two lateral openings.
    The invention is also not limited to the automotive field: the diffusion device can for example be installed in a partition or a false ceiling of a building.
