Definitions

• the invention relates to air distribution devices which comprise at least two air guide fins and which may be part of a heating and / or air conditioning system.
• Some air distribution devices sometimes called air diffusers, comprise a hollow body inside which are mounted rotating rigid fins which are intended to guide the air, which comes from an upstream zone (by example a distribution duct of a heating installation and / or air conditioning (possibly vehicle)), towards a selected area downstream (for example a vehicle interior).
• an upstream zone by example a distribution duct of a heating installation and / or air conditioning (possibly vehicle)
• a selected area downstream for example a vehicle interior
• These fins can be driven simultaneously between a first extreme position which is intended to prohibit the passage of air and a second extreme position which allows the passage of air in a certain guiding direction.
• the first end of most fins is located substantially parallel to the second end of a subsequent fin.
• a trickle of air may continue to pass, which may, in some cases, be a nuisance and / or produce a slight hissing sound.
• a device dedicated to the distribution of air comprising at least two fins capable of guiding air coming from an upstream zone, provided with first and second opposite faces and rotatably mounted so as to be able to be driven simultaneously between first and second extreme positions that prohibit and allow the passage of air, respectively.
• each fin comprises first and second opposite ends and provided on their first and second faces respectively of first and second deformations which have complementary shapes so that the first deformation of a fin and the second deformation of the following fin may interlock with one another to provide local air tightness when these fins are placed in their first extreme position.
• the device according to the invention may comprise other characteristics that can be taken separately or in combination, and in particular:
• Each first deformation may be a groove and each second deformation may be a clean rib to be housed in a groove.
• each first deformation can be a
• Rib and each second deformation may be a groove adapted to house a rib
• the first and second deformations may be defined substantially parallel to the axis of rotation of the fins
• the groove and rib may have complementary shapes) semi circular cylindrical;
• the fins may be arranged so that, when they are placed in their first extreme position, the first face of the first end of one of them is substantially pressed against the second face of the second end of the next fin.
• the invention also proposes a heating and / or air-conditioning installation for an enclosure (such as for example a vehicle interior, possibly an automobile interior), comprising at least one air distribution device of the type of that presented above.
• an enclosure such as for example a vehicle interior, possibly an automobile interior
• at least one air distribution device of the type of that presented above.
• the invention is well adapted, although not limited to vehicles, possibly of the automotive type.
• FIG. 1 schematically and functionally illustrates, in a perspective view of the front side, a portion of an exemplary embodiment of an air distribution device according to the invention, with its fins placed.
• FIG. 2 diagrammatically and functionally illustrates, in a perspective view of the front side, the air distribution device of FIG. 1, with its fins placed in a first extreme position, and
• FIG. 3 illustrates schematically and functionally, in a partial perspective view, the shape cooperation between the first and second deformations of two successive fins when they are placed in their first extreme position.
• the object of the invention is to provide an air distribution device or air diffuser (DA) with rotary air guide vanes (Ai).
• the air distribution device (DA) is part of a heating and / or air conditioning system which is itself intended to supply air) (optionally treated) a vehicle interior, possibly of automotive type.
• the invention is not limited to this type of application.
• the air distribution device (DA) may not be part of an installation heating and / or air conditioning (for example, it can be housed in an opening of a wall to serve as an interface), or it can be part of a heating and / or air conditioning system that is intended to supply in air (possibly treated) an enclosure which is not a cockpit of
• FIGS. 1 and 2 show schematically a portion of a non-limiting exemplary embodiment of an air distribution device DA according to the invention.
• This device (air distribution) DA comprises a hollow body CC in the form of a housing.
• the latter (CC) comprises a rear face provided with a
• Such a device (or air diffuser) DA may, for example, be
• These fins Ai can be driven simultaneously in rotation between a first extreme position, illustrated in FIG. 2 and intended to prevent the passage of air, and a second extreme position, illustrated on FIG.
• the fins Ai can be placed in many intermediate positions between the first and second extreme positions and to guide the air in different directions.
• each wing Ai comprises first E1 and second
• E2 ends opposite to each other and first F1 and second F2 faces.
• the first face F1 is that which is oriented towards the rear face (or upstream) of the hollow body CC when the fin Ai is placed in its first extreme position (see FIG. 2).
• the second face F2 is the one that is oriented towards the front face (or downstream) of the hollow body CC when the fin Ai is placed in its first extreme position (see FIG. 2).
• the fins Ai are preferably coupled to each other by means of a mechanism intended to drive them in rotation simultaneously (and thus jointly) with respect to the hollow body.
• a mechanism may, for example, comprise a drive rod (or slider) which is for example coupled to a lever or wheel manually operable by a person.
• this rod may only be used to couple the fins Ai to one another so that the rotation drive of one of them, manually, simultaneously causes the rotation of the others.
• the fins Ai are not necessarily all identical. They can indeed have variations of shape and / or dimensions.
• hollow body CC may, for example, be made by molding a plastic or synthetic material, or alloy or metal.
• the first end E1 of each fin Ai) comprises on its first face F1 a first deformation DF1 having a first shape
• the second end E2 of each fin Ai comprises on its second face F2 a second deformation DF2 having a second form complementary to the first form (that is to say, can marry closely the latter).
• each intermediate fin (here A2 or A3) cooperates, with a view to airtightness, with the two fins which surround it (here A1 and A3 or A2 and A4).
• the second deformation DF2 of the first end fin A1 may come to bear on a protrusion of the neighboring lateral wall to ensure the sealing locally, and the first deformation DF1 of the second end fin A4 may come to rest on a recess (or a protuberance) of the neighboring side wall for
• each first deformation DF1 of a fin Ai could be arranged in the form of a rib (convex) and therefore each second deformation DF2 of a fin Ai could be arranged in the form of a groove ( concave) which is suitable for housing a
• the first DF1 and second DF2 deformations are defined substantially parallel to the axes of rotation of the fins Ai. This makes it possible to optimize the nesting by shape cooperation and thus to optimize the sealing. But,
• first DF1 and second DF2 deformations could, for example, be defined substantially parallel to an axis slightly inclined relative to the axes of rotation of the fins Ai.
• the grooves DF1 and ribs DF2 have circular semicircular complementary shapes. This also makes it possible to optimize the nesting by shape cooperation and thus to optimize the sealing. But, this is not mandatory. Indeed, other complementary forms may be considered, and in particular semi-oval or triangular.
• each fin Ai may, for example, be made by molding a plastic or synthetic material.
• the wings Ai may optionally have a seal on at least part of their peripheral edge.
• a seal may be overmolded or glued, for example.
• the invention is not limited to the embodiments of air distribution device and heating and / or air conditioning installation described above, only by way of example, but it encompasses all variants that may be considered those skilled in the art within the scope of the claims below.
