Description

La présente invention a pour objet une installation de chauffage et/ou de climatisation présentant un ensemble pulseur d'air comportant un support moteur monté sur un boítier.The subject of the present invention is a heating and / or air conditioning system having an air blower assembly comprising a engine mount mounted on a housing.

Une telle installation est connue notamment de la Demande de Brevet Français FR 2 741 842 déposée le 30 Novembre 1995 par la Demanderesse.Such an installation is known in particular from French Patent Application FR 2,741,842 filed on November 30, 1995 by the Applicant.

Dans celle-ci, le support moteur présente une jupe annulaire plane, ainsi que des moyens de fixation de type baïonnette en vue de la fixation sur une paroi annulaire du boítier.In this, the engine mount has a flat annular skirt, as well as means for fixing bayonet type for attachment to a wall annular case.

Ce type de fixation convient particulièrement au cas de pulseurs dont la volute présente une section croissante en fonction de l'angle, depuis l'entrée vers la sortie de la volute.This type of attachment is particularly suitable in the case of blowers whose volute has a section increasing according to the angle, from the entrance to the exit of the scroll.

La mise en oeuvre de cette solution dans le cas d'une volute qui présente une double évolution (axiale et radiale) n'est pas satisfaisante, car la recherche d'une région d'étanchéité annulaire plane implique de supprimer toute évolution axiale de la volute dans la région d'étanchéité entre le support moteur et le boítier.The implementation of this solution in the case of a volute which presents a double evolution (axial and radial) is not satisfactory, because the search for a planar annular sealing region involves removing any axial evolution of the volute in the region seal between the engine mount and the housing.

L'idée de base de l'invention est de réaliser la liaison entre le support moteur et le boítier dans une région hélicoïdale.The basic idea of the invention is to realize the connection between the engine mount and the housing in a helical region.

L'invention concerne ainsi une installation de chauffage et/ou de climatisation présentant un ensemble pulseur comportant un support moteur monté sur un boítier, caractérisée en ce que le support moteur et le boítier présentent respectivement une première et une deuxième rampe d'étanchéité dont l'une est une jupe d'étanchéité et dont l'autre est un bord d'étanchéité, et en ce que le support moteur et le boítier présentent chacun au moins une rampe de vissage inclinée, de manière que dans une position de vissage du support moteur sur le boítier, la jupe d'étanchéité soit plaquée contre le bord d'étanchéité.The invention thus relates to an installation of heating and / or air conditioning having a set blower comprising a motor support mounted on a housing, characterized in that the motor support and the case present respectively a first and a second sealing ramp, one of which is a skirt and the other of which is a sealing edge, and in that the motor support and the housing have each at least one inclined screwing ramp, so that in a screwing position of the motor support on the housing, the sealing skirt is pressed against the edge sealing.

Ledit plaquage de la jupe d'étanchéité sur le bord d'étanchéité est avantageusement réalisé de manière à impliquer une déformation élastique de la jupe d'étanchéité. Cette déformation peut suffire à créer une étanchéité satisfaisante, sans interposition d'un joint.Said plating of the sealing skirt on the sealing edge is advantageously made so to involve an elastic deformation of the skirt sealing. This deformation can be enough to create a satisfactory sealing, without interposition of a seal.

Avantageusement, la première rampe d'étanchéité, portée par le support moteur, est une jupe d'étanchéité, et la deuxième rampe d'étanchéité, portée par le boítier, est un bord d'étanchéité.Advantageously, the first ramp sealing, carried by the engine support, is a skirt sealing, and the second sealing ramp, carried by the housing, is a sealing edge.

Les rampes d'étanchéité et/ou les rampes de vissage peuvent être hélicoïdales.The sealing ramps and / or the ramps screwing can be helical.

Le support moteur et le boítier présentent avantageusement une pluralité de rampes de vissage.The engine mount and the housing have advantageously a plurality of screwing ramps.

Selon un mode de réalisation préféré, les rampes de vissage du support et du boítier ont des pentes plus accentuées que celles des rampes d'étanchéité, ce qui permet d'effectuer un verrouillage progressif.According to a preferred embodiment, the support and housing screwing ramps have slopes more accentuated than those of the sealing ramps, this which allows for progressive locking.

Les rampes de vissage du support moteur et/ou du boítier sont avantageusement formées de plusieurs tronçons espacés angulairement les uns des autres et décalés axialement l'un par rapport à l'autre dans la direction axiale (Z) de l'ensemble pulseur.The engine support screwing ramps and / or of the housing are advantageously formed of several sections spaced angularly from each other and axially offset from each other in the axial direction (Z) of the blower assembly.

L'invention peut être caractérisée en ce que les rampes de vissage sont disposées de manière telle que, au fur et à mesure du vissage du support moteur sur le boítier :
   - dans un premier temps, une face externe d'au moins une rampe de vissage du support moteur soit en contact avec une face externe d'au moins une rampe de vissage du boítier, en maintenant espacées la jupe d'étanchéité et la rampe d'étanchéité.The invention can be characterized in that the screwing ramps are arranged in such a way that, as and when the motor support is screwed onto the housing:
- As a first step, an external face of at least one screwing ramp of the motor support is in contact with an external face of at least one screwing ramp of the housing, keeping the sealing skirt and the ramp apart sealing.

Par exemple, cet espacement e diminue progressivement jusqu'à ce que la jupe d'étanchéité et la rampe d'étanchéité viennent en contact (début du deuxième temps).

  • dans un deuxième temps, la jupe d'étanchéité glisse sur le bord d'étanchéité, sans que les rampes de vissage du support moteur et du boítier soient en contact ;
  • dans un troisième temps, par mise en contact entre des faces internes des rampes de vissage du support moteur et du boítier, la jupe d'étanchéité soit déformée élastiquement contre le bord d'étanchéité.
For example, this spacing e gradually decreases until the sealing skirt and the sealing ramp come into contact (start of the second step).
  • in a second step, the sealing skirt slides on the sealing edge, without the screwing ramps of the engine support and the housing being in contact;
  • thirdly, by bringing into contact between the internal faces of the screwing ramps of the motor support and of the housing, the sealing skirt is elastically deformed against the sealing edge.

La rampe d'étanchéité du support moteur peut présenter des extrémités raccordées par une rampe inclinée. Une rampe de vissage du support moteur peut alors présenter des demi-rampes disposées de part et d'autre de la rampe inclinée.The engine support sealing ramp can have ends connected by a ramp tilted. An engine support screwing ramp can then present half-ramps arranged on the side and on the other side of the inclined ramp.

Dans ledit premier temps, la face externe d'une première demi-rampe peut être en contact avec la face externe d'une rampe de vissage du boítier, tandis que la deuxième demi-rampe n'est pas en contact avec une rampe de vissage du boítier.In said first step, the external face a first half-ramp can be in contact with the external face of a housing screwing ramp, while that the second half-ramp is not in contact with a screwing ramp of the housing.

Dans ledit troisième temps, la face interne d'une deuxième demi-rampe peut être en contact avec la face interne d'une rampe de vissage du boítier, alors que la première demi-rampe n'est pas en contact avec une rampe de vissage du boítier.In said third step, the internal face a second half-ramp can be in contact with the internal face of a housing screwing ramp, while the first half-ramp is not in contact with a screwing ramp of the housing.

L'étanchéité, avantageusement réalisée par la jupe d'étanchéité déformée élastiquement sur le bord d'étanchéité, peut éventuellement être réalisée, de façon complémentaire ou alternative, par un joint, notamment rapporté, par exemple par surmoulage, formé par exemple dans un matériau du type élastomère, et porté par la rampe d'étanchéité du boítier et/ou par la rampe d'étanchéité du support moteur.Sealing, advantageously achieved by the sealing skirt elastically deformed on the edge sealing, can possibly be carried out, so complementary or alternative, by a joint, in particular reported, for example by overmolding, formed for example in a material of the elastomer type, and carried by the housing sealing ramp and / or by the ramp the engine support.

L'invention s'applique particulièrement au cas d'un pulseur dont la volute présente au moins une évolution axiale en hélice, et dans ce cas, il est avantageux que la deuxième rampe d'étanchéité présente sensiblement la même évolution hélicoïdale que la volute.The invention is particularly applicable to the case a pulser whose volute has at least one axial helical evolution, and in this case it is advantageous that the second sealing ramp has substantially the same helical evolution as the scroll.

D'autres caractéristiques et avantages de l'invention apparaítront mieux à la lecture de la description qui va suivre, donnée à titre d'exemple non limitatif, en liaison avec les dessins annexés, dans lesquels :

  • les figures 1a et 1b représentent respectivement en perspective et en vue latérale, un support moteur selon un mode de réalisation préféré de l'invention ;
  • les figures 2a et 2b illustrent respectivement en coupe partielle et en vue de profil, la mise en place par vissage du support moteur selon les figures la et lb, sur un boítier de pulseur ;
  • et les figures 3a à 3c illustrent les étapes de ce montage, dans le cas d'un boítier de pulseur présentant une virole à évolution radiale et axiale.
Other characteristics and advantages of the invention will appear better on reading the description which follows, given by way of nonlimiting example, in conjunction with the appended drawings, in which:
  • Figures 1a and 1b show respectively in perspective and in side view, a motor support according to a preferred embodiment of the invention;
  • Figures 2a and 2b respectively illustrate in partial section and in profile view, the establishment by screwing of the motor support according to Figures la and lb, on a blower housing;
  • and Figures 3a to 3c illustrate the stages of this assembly, in the case of a blower housing having a ferrule with radial and axial evolution.

Selon les figures 1a et 1b, un support moteur 1 est constitué par une pièce moulée, généralement en matière plastique. Le support présente un logement de moteur 10 entouré par une région annulaire délimitée par un fond incliné 17 et un bord interne 18 d'un canal d'une virole 25 (voir figure 2a).According to Figures 1a and 1b, a motor support 1 is constituted by a molded part, generally in plastic material. The support has a housing for motor 10 surrounded by an annular region delimited by an inclined bottom 17 and an internal edge 18 of a channel of a ferrule 25 (see FIG. 2a).

Un bord hélicoïdal 12 est longé par une jupe 14, avantageusement réalisée de manière à être déformable de manière élastique par appui sur sa face 141 qui coopère avec un bord d'étanchéité 24 du boítier 2 (voir figure 2a). Les extrémités 12a et 12b du bord hélicoïdal 12 peuvent être raccordées entre elles par une rampe de remontée inclinée 100.A helical edge 12 is bordered by a skirt 14, advantageously made so as to be elastically deformable by pressing on its face 14 1 which cooperates with a sealing edge 24 of the housing 2 (see FIG. 2a). The ends 12a and 12b of the helical edge 12 can be connected together by an inclined ascent ramp 100.

Le bord interne 19 qui longe la jupe 14 porte des rampes de verrouillage hélicoïdales 16.The internal edge 19 which runs along the skirt 14 carries helical locking ramps 16.

En outre, le trottoir hélicoïdal 12 porte un ou plusieurs éléments d'encliquetage 31 destinés à coopérer avec un ou plusieurs éléments complémentaires 32 du boítier 2 (voir figure 3a à 3c) pour maintenir verrouuillé en position l'ensemble une fois monté.In addition, the helical sidewalk 12 carries a or several snap-in elements 31 intended for cooperate with one or more complementary elements 32 housing 2 (see Figure 3a to 3c) to maintain locked in position once assembled.

Le support moteur 1 porte le moteur 1' (figure 2a) et une turbine de pulseur 11 (figures 3a à 3c).The engine support 1 carries the engine 1 '(figure 2a) and a blower turbine 11 (Figures 3a to 3c).

Le boítier 2 (figure 2a et 3a à 3c) présente deux demi-volutes 21 et 23 assemblées en 27 et définissant un canal de volute 25 entourant la turbine de pulseur. Sa section augmente progressivement au fur et à mesure que l'on s'approche de sa sortie 29, cette évolution s'effectuant de manière hélicoïdale aussi bien radialement, qu'axialement (selon l'axe Z). L'évolution axiale délimite un bord 22 de profil hélicoïdal.The housing 2 (FIGS. 2a and 3a to 3c) has two half-volutes 21 and 23 assembled at 27 and defining a volute channel 25 surrounding the turbine kicker. Its section gradually increases as as we approach its exit 29, this evolution taking place in a helical manner as well radially, only axially (along the Z axis). Evolution axial delimits an edge 22 of helical profile.

Pour permettre une fixation du support moteur 1 sur le boítier 2, le boítier 2 présente au voisinage de son bord 22, et du côté interne de celui-ci, des rampes hélicoïdales 26 qui coopèrent avec les rampes hélicoïdales précédemment décrites 16 du support moteur 1.To allow fixing of the support motor 1 on the housing 2, the housing 2 present at in the vicinity of its edge 22, and on the internal side thereof, helical ramps 26 which cooperate with the ramps previously described helical 16 of the support motor 1.

Le montage s'effectue de la manière suivante :The assembly is carried out as follows:

Le support moteur 1 est présenté dans l'axe du boítier 2 (figure 3a) ; il est ensuite abaissé dans la direction Z pour être positionné sur le boítier 2 (figure 3b). Dans cette position d'approche et de guidage (premier temps), et comme illustré à la partie gauche de la figure 2b, la face d'appui externe 161 des rampes 16 est en contact avec la face d'appui externe 261 des rampes homologues 26 en maintenant la jupe 14 espacée de la rampe d'étanchéité 24, d'une distance e (voir partie gauche de la figure 2b). Une rotation du support 1 diminue cette distance e jusqu'à l'annuler. La jupe 14 repose alors (sans déformation) sur la rampe 24 et les rampes 16 et 26 ne sont plus en contact. La jupe 14 glisse sur la rampe d'étanchéité sur une zone angulaire de glissement (deuxième temps). La poursuite de la rotation du support 1 a pour effet qu'au début du troisième temps, les rampes 16 viennent en contact par leur face d'appui interne 162 avec la face d'appui interne 262 des rampes 26 qui suivent les rampes 26 précédentes par permutation circulaire.The engine support 1 is presented in the axis of the housing 2 (Figure 3a); it is then lowered in the Z direction to be positioned on the housing 2 (Figure 3b). In this approach and guide position (first step), and as illustrated in the left part of FIG. 2b, the external support face 16 1 of the ramps 16 is in contact with the external support face 26 1 of the homologous ramps 26 while maintaining the skirt 14 spaced from the sealing ramp 24, by a distance e (see left part of FIG. 2b). A rotation of the support 1 decreases this distance e until canceling it. The skirt 14 then rests (without deformation) on the ramp 24 and the ramps 16 and 26 are no longer in contact. The skirt 14 slides on the sealing ramp over an angular sliding zone (second step). Continued rotation of the support 1 has the effect that at the start of the third stage, the ramps 16 come into contact via their internal support face 16 2 with the internal support face 26 2 of the ramps 26 which follow the ramps 26 previous ones by circular permutation.

A cet effet, les tronçons successifs des rampes 16 et 26 ne sont pas situés dans la continuité des uns des autres, comme le voudrait leur évolution en hélice, mais sont au contraire, décalés axialement (axe X) par rapport à cette continuité, d'une distance ΔX (voir fig. 2b).To this end, the successive sections of ramps 16 and 26 are not located in the continuity of the each other, as their evolution in propeller, but are on the contrary, axially offset (axis X) with respect to this continuity, by a distance ΔX (see fig. 2b).

Les rampes de vissage 26 ayant un pas supérieur à celui de la rampe d'étanchéité 24, la poursuite du vissage entraíne grâce au contact entre les faces internes 162 et 262 des rampes 16 et 26, une mise en appui progressive de la jupe 14 sur la rampe 24, d'où, dans le troisième temps, une déformation élastique de la jupe 14, jusqu'à encliquetage réciproque des éléments de verrouillage 31, 32. A cette position, on obtient un verrouillage avec étanchéité.The screwing ramps 26 having a pitch greater than that of the sealing ramp 24, the continued screwing results through contact between the internal faces 16 2 and 26 2 of the ramps 16 and 26, a progressive pressing of the skirt 14 on the ramp 24, from where, in the third step, an elastic deformation of the skirt 14, until the locking elements 31, 32 interlock. At this position, a locking with sealing is obtained.

L'étendue des zones angulaires de glissement relatif entre le jupe 14 et la rampe 24, et de la zone angulaire de compression de la jupe 14 dépend de l'écart relatif entre les pas de la rampe 24 et des rampes de vissage (16, 26), du jeu fonctionnel entre deux régions de rampe 26 successives et de l'épaisseur des régions de rampe 16.The extent of the angular zones of sliding relative between the skirt 14 and the ramp 24, and of the zone compression angle of the skirt 14 depends on the distance relative between the steps of ramp 24 and ramps of screwing (16, 26), of the functional play between two regions of ramp 26 successive and of the thickness of the regions of ramp 16.

Par exemple, la zone de glissement relatif A peut s'étendre sur 25° environ et la zone de serrage B peut s'étendre sur 10° environ.For example, the relative sliding zone A can extend over approximately 25 ° and the clamping area B can extend over approximately 10 °.

L'invention permet ainsi de réaliser une étanchéité sur une zone hélicoïdale par déformation d'une jupe souple 14, qui peut être située sur le support moteur 1. La régularité de la rampe permet d'assurer cette fonction avec une large dispersion angulaire sur la position du moteur.The invention thus makes it possible to carry out a sealing on a helical area by deformation of a flexible skirt 14, which can be located on the support motor 1. The regularity of the ramp ensures this function with a wide angular dispersion on the motor position.

Les rampes de vissage permettent de limiter la course angulaire pendant laquelle la jupe est comprimée au cours du montage pour assurer l'étanchéité, grâce à la différence de pas entre la rampe d'étanchéité et les rampes de vissage.The screwing ramps limit the angular stroke during which the skirt is compressed during assembly to ensure sealing, thanks to the difference in pitch between the sealing ramp and the screwing ramps.

Bien entendu, d'autres formes que des rampes hélicoïdales peuvent être prévues. Par exemple, les rampes 26 peuvent avoir un profil assurant un guidage selon un parcours, de tout profil souhaité, et les rampes 16 peuvent avoir des dimensions réduites pour pouvoir suivre tout profil quelconque éventuellement choisi pour les rampes 16.Of course, other forms than ramps helical can be provided. For example, ramps 26 may have a profile ensuring guidance according to a route, of any desired profile, and the ramps 16 may have reduced dimensions in order to be able follow any profile that may be chosen for the ramps 16.

Les rampes de vissages 16a et 16b, qui sont situées près des extrémités 12a et 12b du bord 12 qui sont raccordées par la rampe de remontée 100, constituent avantageusement deux demi-rampes qui assurent chacune une partie des fonctions des autres rampes.The screwing ramps 16a and 16b, which are located near the ends 12a and 12b of the edge 12 which are connected by the ascent ramp 100, constitute advantageously two half-ramps which each provide a part of the functions of the other ramps.

Pendant le premier temps, la face externe 161 de la rampe de vissage 16b du support moteur 1 est en contact avec la face externe 261 d'une rampe de vissage 26 du boítier 2, tandis que la rampe de vissage 16a du support moteur 1 n'est pas en contact avec une rampe de vissage du boítier. Pendant le troisième temps, la face interne 162 de la rampe de vissage 16a du support moteur 1 est en contact avec la face interne 262 d'une rampe de vissage 26 du boítier 2, tandis que la rampe de vissage 16b du support moteur 1 n'est pas en contact avec une rampe de vissage du boítier 2.During the first time, the external face 16 1 of the screwing ramp 16b of the motor support 1 is in contact with the external face 26 1 of a screwing ramp 26 of the housing 2, while the screwing ramp 16a of the motor support 1 is not in contact with a screwing ramp of the housing. During the third stage, the internal face 16 2 of the screwing ramp 16a of the motor support 1 is in contact with the internal face 26 2 of a screwing ramp 26 of the housing 2, while the screwing ramp 16b of the motor support 1 is not in contact with a screwing ramp of the housing 2.
