Description
Dispositif de filtration d'air pour une installation de chauffage et/ou climatisation de véhicule automobile
L'invention concerne un dispositif de filtration d'air pour une installation de chauffage et/ou climatisation de véhicule automobile.Air filtration device for a heating and / or air conditioning installation of a motor vehicle
The invention relates to an air filtration device for a heating and / or air conditioning installation of a motor vehicle.
Le dispositif de l'invention est du type comprenant une cartouche filtrante propre à être introduite, par un montage en tiroir, dans un logement ménagé transversalement dans un conduit d'air, cette cartouche étant munie d'un couvercle propre à obturer une ouverture d'accès au logement, ménagée dans une paroi latérale du conduit.The device of the invention is of the type comprising a filter cartridge suitable for being introduced, by a drawer assembly, into a housing formed transversely in an air duct, this cartridge being provided with a cover suitable for closing an opening d access to the housing, formed in a side wall of the duct.
Le Brevet DE-4234047 décrit un dispositif de filtration de ce type, dans lequel la cartouche filtrante est réalisée sous la forme d'une cassette qui est immobilisée dans le conduit par au moins une agrafe venant coopérer avec des moyens d'ancrage appropriés aménagés sur l'extérieur du couvercle et sur l'extérieur de la paroi latérale du conduit.Patent DE-4234047 describes a filtration device of this type, in which the filter cartridge is produced in the form of a cassette which is immobilized in the duct by at least one clip coming to cooperate with suitable anchoring means arranged on outside the cover and on the outside of the side wall of the duct.
Cette solution est complexe à réaliser et ne permet pas un montage ou démontage aisé de la cartouche filtrante. En outre, il peut arriver que, sous l'action des vibrations, l'agrafe se désolidarise du couvercle et du conduit, et que la cartouche filtrante quitte son logement, ce qui non seulement supprime la filtration d'air mais aussi crée une fuite d'air dans le conduit.This solution is complex to carry out and does not allow easy assembly or disassembly of the filter cartridge. In addition, it may happen that, under the action of vibrations, the clip detaches from the cover and the duct, and the filter cartridge leaves its housing, which not only eliminates air filtration but also creates a leak air in the duct.
L'invention a notamment pour but de surmonter les inconvénients précités.The object of the invention is in particular to overcome the aforementioned drawbacks.
Elle propose à cet effet un dispositif de filtration du type défini en introduction, dans lequel le couvercle de la cartouche est muni dune lèvre périphérique compressible propre à se loger dans un rebord périphérique de forme adaptée qui est rattaché à la paroi latérale du conduit d'air et entoure l'ouverture d'accès. To this end, it offers a filtration device of the type defined in the introduction, in which the cover of the cartridge is provided with a compressible peripheral lip capable of being housed in a peripheral rim of suitable shape which is attached to the side wall of the conduit. air and surrounds the access opening.
Ainsi, cette lèvre périphérique assure à la fois l'immobilisation de la cartouche filtrante et l'étanchéité entre le couvercle de la cartouche filtrante et la paroi latérale du conduit.Thus, this peripheral lip ensures both the immobilization of the filter cartridge and the seal between the cover of the filter cartridge and the side wall of the duct.
La lèvre périphérique comprend avantageusement un bourrelet propre à s'engager dans une partie de retenue délimitée par le rebord périphérique.The peripheral lip advantageously comprises a bead capable of engaging in a retaining part delimited by the peripheral rim.
Dans une forme de réalisation préférée, ce rebord périphérique s'étend vers l'extérieur du conduit et cette partie de retenue est formée au raccordement de la paroi latérale et du rebord périphérique, du côté intérieur du conduit.In a preferred embodiment, this peripheral rim extends towards the outside of the duct and this retaining part is formed at the connection of the side wall and the peripheral rim, on the inside of the duct.
Dans une forme de réalisation de l'invention, cette partie de retenue est formée par un épaulement qui s'étend sur le pourtour de l'ouverture, en sorte que cette partie de retenue présente des dimensions intérieures supérieures aux dimensions intérieures du rebord périphérique.In one embodiment of the invention, this retaining part is formed by a shoulder which extends around the periphery of the opening, so that this retaining part has internal dimensions greater than the internal dimensions of the peripheral rim.
Ces différences de dimensions contribuent au maintien de la cartouche filtrante dans la canalisation, puisqu'elles s'opposent à la sortie de la cartouche filtrante.These differences in dimensions contribute to maintaining the filter cartridge in the pipeline, since they oppose the exit of the filter cartridge.
De façon avantageuse, le rebord périphérique comporte un contour rectangulaire et se rattache perpendiculairement à la paroi latérale du conduit.Advantageously, the peripheral rim has a rectangular outline and is attached perpendicularly to the side wall of the duct.
Selon une autre caractéristique de l'invention, la lèvre périphérique comporte en outre une jupe périphérique qui se rattache au bourrelet périphérique et qui s'étend à l'opposé de la cartouche filtrante, pour être montée en contrainte à l'intérieur du rebord périphérique. Cette jupe périphérique, qui, dans une forme de réalisation préférée, s'évase à partir du bourrelet, contribue à l'immobilisation de la cartouche filtrante dans le conduit.According to another characteristic of the invention, the peripheral lip further comprises a peripheral skirt which is connected to the peripheral bead and which extends opposite the filter cartridge, to be mounted under stress inside the peripheral rim . This peripheral skirt, which, in a preferred embodiment, flares from the bead, contributes to the immobilization of the filter cartridge in the duct.
La lèvre périphérique est avantageusement surmoulée sur une plaque d'extrémité de la cartouche. The peripheral lip is advantageously overmolded on an end plate of the cartridge.
Avantageusement, cette plaque d'extrémité comporte un élément de préhension faisant saillie vers l'extérieur de la cartouche, ce qui facilite son montage ou son démontage.Advantageously, this end plate comprises a gripping element projecting towards the outside of the cartridge, which facilitates its assembly or disassembly.
La lèvre périphérique est avantageusement formée par moulage d'un matériau élastomère.The peripheral lip is advantageously formed by molding an elastomeric material.
Selon une autre caractéristique de l'invention, la cartouche filtrante comporte, sur une face opposée au couvercle, un joint d'étanchéité propre à prendre appui contre une autre paroi latérale du conduit, qui est située à l'opposé de la paroi latérale munie de l'ouverture d'accès.According to another characteristic of the invention, the filter cartridge comprises, on a face opposite the cover, a seal capable of bearing against another side wall of the duct, which is located opposite the side wall provided of the access opening.
Dans la description qui suit, faite seulement à titre d'exemple, on se réfère au dessin annexé, sur lequel - la figure 1 est une vue en coupe longitudinale partielle d'un conduit d'air d'une installation de chauffage-ventilation et/ou climatisation de véhicule automobile, équipé d'une cartouche filtrante selon l'invention, cette dernière étant représentée en position montée; et - la figure 2 est une vue en coupe partielle analogue à celle de la figure 1 montrant la position de la cartouche filtrante avant introduction complète dans son logement du conduit.In the description which follows, made only by way of example, reference is made to the appended drawing, in which - FIG. 1 is a view in partial longitudinal section of an air duct of a heating-ventilation installation and / or air conditioning of a motor vehicle, equipped with a filter cartridge according to the invention, the latter being shown in the assembled position; and - Figure 2 is a partial sectional view similar to that of Figure 1 showing the position of the filter cartridge before complete introduction into its housing of the conduit.
Le dispositif représenté à la figure 1 comprend un conduit 10 faisant partie d'une installation de chauffage-ventilation et/ou climatisation d'un véhicule automobile et destiné à être parcouru par un flux d'air A circulant dans le conduit sous l'action d'une turbine (non représentée).The device represented in FIG. 1 comprises a duct 10 forming part of a heating-ventilation and / or air conditioning installation of a motor vehicle and intended to be traversed by a flow of air A circulating in the duct under the action of a turbine (not shown).
Le conduit 10 a une section transversale de forme générale rectangulaire et il est limité notamment par une première paroi latérale 12 et par une seconde paroi latérale 14, située à l'opposé de la paroi 12.The duct 10 has a generally rectangular cross section and is limited in particular by a first side wall 12 and by a second side wall 14, located opposite the wall 12.
Le conduit 10 comporte un logement transversal 16 accessible à partir d'une ouverture 18 de la paroi 12. Le logement 16 est destiné à recevoir une cartouche filtrante 20 par un montage du type tiroir dans la direction de la flèche F. La cartouche filtrante 20 est un élément remplaçable comprenant un corps filtrant 22 servant à retenir les particules diverses, notamment de poussière, contenues dans l'air devant être admis dans l'habitacle du véhicule. Cette cartouche filtrante peut servir également à retenir les odeurs contenues dans l'air à filtrer.The conduit 10 comprises a transverse housing 16 accessible from an opening 18 of the wall 12. The housing 16 is intended to receive a filter cartridge 20 by a drawer-type assembly in the direction of the arrow F. The filter cartridge 20 is a replaceable element comprising a filter body 22 serving to retain various particles, in particular dust, contained in the air to be admitted into the passenger compartment of the vehicle. This filter cartridge can also be used to retain odors contained in the air to be filtered.
Le corps filtrant 22 a une forme générale parallélépipédique et il présente deux grandes faces opposées 24 et 26 s'étendant transversalement dans le conduit et deux petites faces opposées 28 et 30 situées respectivement du côté de la paroi 12 et du côté de la paroi 14 du conduit.The filter body 22 has a generally parallelepiped shape and it has two large opposite faces 24 and 26 extending transversely in the duct and two small opposite faces 28 and 30 situated respectively on the side of the wall 12 and on the side of the wall 14 of the drove.
La face 30 du corps 22 est munie d'un joint d'étanchéité 32, par exemple en mousse, destiné à être comprimé contre un fond 34 formé en creux dans la paroi 14.The face 30 of the body 22 is provided with a seal 32, for example made of foam, intended to be compressed against a bottom 34 formed hollow in the wall 14.
La cartouche filtrante 20 comporte, du côté de la face 28, un couvercle 36 destiné à assurer la fixation de la cartouche filtrante 20 dans le logement 16 et la fermeture étanche de l'ouverture 18 ménagée dans la paroi 12.The filter cartridge 20 comprises, on the side of the face 28, a cover 36 intended to secure the filter cartridge 20 in the housing 16 and the sealed closure of the opening 18 provided in the wall 12.
Le couvercle 36 est réalisé monobloc avec le corps filtrant 22 et comprend une plaque d'extrémité 38, de forme générale rectangulaire, solidaire de la face 28 de la cartouche 20.The cover 36 is made in one piece with the filter body 22 and comprises an end plate 38, of generally rectangular shape, integral with the face 28 of the cartridge 20.
Cette plaque d'extrémité comporte un élément de préhension 40 qui fait saillie vers l'extérieur de la cartouche filtrante 20 et qui facilite la manipulation de cette dernière pour son montage ou son démontage.This end plate comprises a gripping element 40 which projects outwards from the filter cartridge 20 and which facilitates the handling of the latter for its assembly or disassembly.
Sur la plaque d'extrémité 38 est surmoulée une lèvre périphérique compressible 42 qui s'étend sur tout le pourtour de la plaque 38. Cette lèvre périphérique 42 comprend un bourrelet 44 de contour général rectangulaire prolongé par une jupe périphérique 46 qui se rattache au bourrelet 44 et qui s'étend à l'opposé de la cartouche filtrante 20. On the end plate 38 is overmolded a compressible peripheral lip 42 which extends over the entire periphery of the plate 38. This peripheral lip 42 comprises a bead 44 of generally rectangular outline extended by a peripheral skirt 46 which is attached to the bead 44 and which extends opposite the filter cartridge 20.
L'ouverture 18 de la paroi 12 est délimitée par un rebord périphérique 48, de forme adaptée à la lèvre périphérique 42, et rattaché à la paroi latérale 12. Ce rebord périphérique présente un contour rectangulaire et se rattache perpendiculairement à la paroi latérale 12, vers l'extérieur du conduit 10. Ce rebord comporte un épaulement 50 qui s'étend sur tout le pourtour de l'ouverture, au niveau du raccordement de la paroi latérale 12 et du rebord périphérique 48, ce qui permet de définir une partie de retenue 52. Cette partie de retenue 52 a une forme générale rectangulaire et elle possède des dimensions, en longueur et en largeur, supérieures aux dimensions intérieures du rebord périphérique. Cette partie de retenue 52 est destinée à recevoir le bourrelet 44, comme on le voit sur la figure 1.The opening 18 of the wall 12 is delimited by a peripheral rim 48, of a shape adapted to the peripheral lip 42, and attached to the side wall 12. This peripheral rim has a rectangular outline and is attached perpendicularly to the side wall 12, towards the outside of the duct 10. This flange has a shoulder 50 which extends over the entire periphery of the opening, at the connection of the side wall 12 and the peripheral flange 48, which makes it possible to define a part of retaining 52. This retaining part 52 has a generally rectangular shape and has dimensions, in length and in width, greater than the internal dimensions of the peripheral rim. This retaining part 52 is intended to receive the bead 44, as seen in FIG. 1.
La lèvre périphérique 42, comprenant le bourrelet périphérique 44 et la jupe périphérique 46, est surmoulée sur la plaque d'extrémité 38, de manière que l'élément de préhension 40 fasse saillie vers l'extérieur.The peripheral lip 42, comprising the peripheral bead 44 and the peripheral skirt 46, is overmolded on the end plate 38, so that the gripping element 40 projects outwards.
La lèvre périphérique 42 est avantageusement surmoulée en un matériau élastomère.The peripheral lip 42 is advantageously molded in an elastomeric material.
Le surmoulage est réalisé de telle sorte que la jupe 46 ait une configuration évasée, comme montré à la figure 2.The overmolding is carried out so that the skirt 46 has a flared configuration, as shown in FIG. 2.
Pour réaliser le montage de la cartouche filtrante 20 dans le conduit 10, on introduit cette dernière par l'ouverture 18 du conduit 10 dans la direction de la flèche F. Il en résulte que la face 30 de la cartouche filtrante se rapproche progressivement du fond 34 de la paroi 14. Simultanément, la lèvre périphérique 42 se rapproche du rebord périphérique 48.To assemble the filter cartridge 20 in the conduit 10, the latter is introduced through the opening 18 of the conduit 10 in the direction of the arrow F. As a result, the face 30 of the filter cartridge gradually approaches the bottom 34 of the wall 14. Simultaneously, the peripheral lip 42 approaches the peripheral rim 48.
Peu avant de parvenir au rebord périphérique 48 (figure 2), le bourrelet 44 se trouve encore à l'état non comprimé. Ses dimensions extérieures (longueur et largeur) sont supérieures aux dimensions intérieures (longueur et largeur) du rebord 48. Au fur et à mesure du mouvement d'introduction, le bourrelet périphérique 44 est comprimé, de même que la jupe 46 qui vient s'adapter étroitement contre l'intérieur du rebord périphérique 48.Shortly before reaching the peripheral rim 48 (FIG. 2), the bead 44 is still in the uncompressed state. Its external dimensions (length and width) are greater than the internal dimensions (length and width) of the flange 48. As the insertion movement progresses, the peripheral bead 44 is compressed, as is the skirt 46 which comes fit tightly against the inside of the peripheral rim 48.
En fin de course d'introduction, le joint d'étanchéité 32 prévu sur la face 30 est comprimé par contact avec le fond 34. En outre, le bourrelet 44 vient se loger dans la partie de retenue 52, tandis que la jupe 46 est sollicitée en contrainte par le rebord périphérique 48.At the end of the introduction stroke, the seal 32 provided on the face 30 is compressed by contact with the bottom 34. In addition, the bead 44 is received in the retaining part 52, while the skirt 46 is stressed under stress by the peripheral edge 48.
Il en résulte que la cartouche 20 est fixée dans le conduit 10 par coopération de la lèvre périphérique 42 et du rebord périphérique 48. En outre, une étanchéité est ainsi obtenue, ce qui évite toute fuite d'air par l'ouverture 18.As a result, the cartridge 20 is fixed in the conduit 10 by cooperation of the peripheral lip 42 and the peripheral rim 48. Furthermore, a seal is thus obtained, which prevents any air leakage through the opening 18.
Si l'on souhaite enlever la cartouche filtrante 20, lorsqu'elle est usagée, pour la remplacer par une neuve, il suffit d'exercer une traction sur l'élément de préhension 40 dans une direction opposée à celle de la flèche F. Au fur et à mesure de cette traction, la lèvre périphérique 42 se contracte au passage du rebord 48 et s'expanse ensuite.If it is desired to remove the filter cartridge 20, when it is used, to replace it with a new one, it suffices to exert traction on the gripping element 40 in a direction opposite to that of the arrow F. Au as this traction progresses, the peripheral lip 42 contracts when the rim 48 passes and then expands.
Dans tous les cas, le montage ou le démontage de la cartouche s'effectue de façon simple et rapide, sans nécessiter d'outillage particulier.In all cases, the assembly or disassembly of the cartridge is carried out in a simple and rapid manner, without requiring any particular tool.
En outre, cette solution évite le recours à une agrafe comme dans le cas de la technique antérieure.In addition, this solution avoids the need for a staple as in the case of the prior art.
De plus, la cartouche filtrante étant montée sous contrainte, elle ne risque pas de quitter son logement sous l'action de vibrations.In addition, the filter cartridge being mounted under stress, it does not risk leaving its housing under the action of vibration.
La cartouche filtrante 20 peut être formée de tout matériau filtrant approprié et est logée de préférence dans une cassette en matière plastique facilitant sa manipulation.The filter cartridge 20 can be formed of any suitable filter material and is preferably housed in a plastic cassette facilitating its handling.
Bien entendu, l'invention n'est pas limitée à la forme de réalisation décrite précédemment et s'étend à d'autres variantes. Of course, the invention is not limited to the embodiment described above and extends to other variants.
Le dispositif de filtration de l'invention est utilisable avant tout à l'entrée d'une installation de chauffage et/ou climatisation de l'habitacle d'un véhicule automobile. The filtration device of the invention can be used above all at the entrance to a heating and / or air conditioning installation of the passenger compartment of a motor vehicle.
