Description

La présente invention se rapporte à une bouche de ventilation auto-réglable.The present invention relates to a self-adjustable ventilation mouth.

Les systèmes de ventilation par extraction seule sont le type de ventilation le plus répandu actuellement dans tous les pays. De tels systèmes comprennent au moins un dispositif de ventilation motorisé (ventilateurs) associés ou non à des conduits et des bouches d'extraction.Extraction ventilation systems alone are the most common type of ventilation currently available in all countries. Such systems include at least one motorized ventilation device (fans) associated or not with ducts and extraction vents.

De manière générale, ces systèmes sont principalement utilisés pour extraire et renouveler l'air des pièces techniques telles que les cuisines, salles de bain, toilettes et rejettent l'air prélevé vers l'extérieur.In general, these systems are mainly used to extract and renew the air of technical rooms such as kitchens, bathrooms, toilets and reject the air taken to the outside.

L'air extrait est remplacé par de l'air neuf qui pénètre à l'intérieur du bâtiment par des entrées d'air passives, c'est-à-dire non motorisées, généralement placées dans les pièces principales, à savoir le séjour et les chambres.The exhaust air is replaced by fresh air that enters the building through passive air inlets, that is to say non-motorized, usually placed in the main rooms, namely the living room and the rooms.

C'est l'effet de la différence de pression entre l'extérieur du logement et l'intérieur qui donne le débit d'air passant à travers les entrées d'air par une relation liant la surface ouverte et la racine carrée de la pression.It is the effect of the pressure difference between the outside of the housing and the inside that gives the air flow passing through the air inlets by a relationship between the open surface and the square root of the pressure. .

En l'absence de vent, l'air entrant se réparti au prorata des surfaces ouvertes.In the absence of wind, incoming air is distributed pro rata open surfaces.

En présence de vent à l'extérieur, la pression générée par celui-ci (1/2 p v2) modifie la répartition de l'air et sa vitesse à chacune des entrées. C'est ainsi qu'un vent de 6 mètres par seconde va générer une pression d'environ 22,5 pascals. Pour une ouverture d'environ 30 cm2, cette surpression se traduit par un débit atteignant environ 43 m3 par heure alors qu'un débit compris entre 15 et 30 m3 par heure est généralement souhaité. Ce débit atteindra presque 90 m3 par heure en présence d'un vent de 12 mètres par seconde.In the presence of wind outside, the pressure generated by it (1/2 pv 2 ) modifies the distribution of air and its speed at each of the inputs. Thus a wind of 6 meters per second will generate a pressure of about 22.5 pascals. For an opening of about 30 cm 2 , this overpressure results in a flow rate of up to about 43 m 3 per hour while a flow rate of between 15 and 30 m 3 per hour is generally desired. This flow will reach nearly 90 m 3 per hour in the presence of a wind of 12 meters per second.

Le résultat est donc une courbe présentant une augmentation très rapide du débit en présence d'un vent extérieur.The result is a curve showing a very rapid increase in flow in the presence of an outside wind.

Ceci n'est pas souhaitable et des dispositifs visant à limiter la gêne ont été imaginés et fabriqués. Il s'agit d'entrées d'air ou d'auvents auto-réglables.This is undesirable and devices to limit discomfort have been devised and manufactured. These are air inlets or self-adjustable awnings.

Dans de telles bouches d'aération, le débit est régulé grâce à un volet ou élément mobile apte à faire varier la section de passage d'air à travers la bouche de ventilation. Le réglage du volet s'effectue par l'équilibre entre une force motrice générée par la différence entre les pressions intérieure et extérieure et une force de rappel générée par la force de gravité s'exerçant sur le volet. Des ressorts ou contrepoids complémentaires permettent éventuellement de s'affranchir de la pesanteur et d'utiliser la bouche dans toutes les positions.In such vents, the flow rate is regulated by a flap or movable element adapted to vary the air passage section through the ventilation mouth. The adjustment of the shutter is achieved by the balance between a driving force generated by the difference between the inner and outer pressures and a restoring force generated by the force of gravity exerted on the blind. Complementary springs or counterweights make it possible to overcome gravity and use the mouth in all positions.

De cette manière, le débit est régulé et reste relativement constant.In this way, the flow rate is regulated and remains relatively constant.

Ce type de bouche de ventilation est bien connu et est utilisé très couramment en France, aussi bien en résidentiel (en terminal) qu'en tertiaire (en terminal ou conduit).This type of ventilation is well known and is used very commonly in France, both in residential (terminal) and tertiary (terminal or conduit).

Les bouches de ventilation à volet plan actuellement proposées pour délivrer un débit fixe prédéterminé sont relativement performantes dans la mesure où elles permettent en général d'obtenir une valeur de débit sensiblement constante sur une plage de pression assez large, avec un hystérésis réduit entre la montée et la descente en pression.The planar flap vents presently proposed for delivering a predetermined fixed flow rate are relatively efficient in that they generally make it possible to obtain a substantially constant flow rate over a fairly wide pressure range, with a reduced hysteresis between the rise and the descent in pressure.

De manière générale, les dispositifs limitant le débit ont recours à des éléments déformables assez fins ou pivotant autour d'un axe ou d'une came. Les éléments à volets pivotants présentent souvent un battement qu'il est nécessaire d'amortir, les éléments déformables fins présentant une certaine fragilité. Par ailleurs, ces battements sont générateurs de bruit et sont donc source d'une pollution sonore non négligeable.In general, devices limiting the flow use deformable elements fairly thin or pivoting about an axis or a cam. The elements with pivoting flaps often have a beat that must be damped, the deformable elements having a certain fragility. Moreover, these beats are noise generators and are therefore a source of significant noise pollution.

Le document FR-A-2798954 divulgue une bouche de ventilation comprenant les caractéristiques du préambule de la revendication 1.The document FR-A-2798954 discloses a ventilation mouth comprising the features of the preamble of claim 1.

La présente invention a pour but de proposer une bouche de ventilation auto-réglable permettant la suppression ou au moins la forte atténuation des bruits générés par les battements du volet de réglage.The object of the present invention is to propose a self-adjusting ventilation opening allowing the suppression or at least the strong attenuation of the noises generated by the beats of the adjustment flap.

Pour ce faire, la présente invention se rapporte à une bouche de ventilation auto-réglable selon la revendication 1.To this end, the present invention relates to a self-adjusting ventilation opening according to claim 1.

Ainsi, contrairement à une bouche de ventilation classique possédant un volet de réglage équipé d'une liaison de type charnière pivotant autour d'un axe rigide, l'articulation du volet de régulation s'effectue ici par flexion des moyens d'attache en matériau élastique souple.Thus, unlike a conventional ventilation opening having a control flap equipped with a hinge type connection pivoting about a rigid axis, the hinge of the control flap is here made by bending the fastening means of material flexible elastic.

Leur caractère élastique fait que les moyens d'attache sont aptes à exercer sur le volet de régulation une force de rappel tendant à le ramener vers sa position d'équilibre.Their elastic nature means that the attachment means are able to exert on the control flap a return force tending to bring it back to its equilibrium position.

En l'espèce cette force de rappel constitue un amortissement aux variations intempestives de vent, les forces tendant à écarter le volet de régulation de sa position d'équilibre étant partiellement compensées par cette force de rappel.In this case, this restoring force is a damping to untimely variations of wind, the forces tending to move the control flap of its equilibrium position being partially compensated by this restoring force.

Par ailleurs, plus le déplacement du volet est important, plus la force de rappel sera élevée.Moreover, the greater the movement of the flap, the higher the return force will be.

Selon l'invention, les moyens d'attache comprennent une pluralité de zones déformables régulièrement disposées le long du bord de liaison du volet.According to the invention, the attachment means comprise a plurality of deformable zones regularly arranged along the connecting edge of the flap.

Avantageusement, les zones déformables se présentent sous la forme de languettes élastiques.Advantageously, the deformable zones are in the form of elastic tongues.

Avantageusement encore, les languettes élastiques sont terminées par des moyens de fixation du volet dans une paroi de la bouche de ventilation.Advantageously, the resilient tongues are terminated by flap fastening means in a wall of the ventilation mouth.

De manière préférentielle, le volet de réglage est réalisé dans la même matière que les zones déformables.Preferably, the adjustment flap is made of the same material as the deformable zones.

Avantageusement, les zones déformables et le volet sont réalisés d'une seule pièce, de préférence par moulage.Advantageously, the deformable zones and the flap are made in one piece, preferably by molding.

De manière complémentaire, le volet de réglage présente au moins une zone d'amortissement sur au moins une face dudit volet de réglage.In a complementary manner, the adjustment flap has at least one damping zone on at least one face of said adjustment flap.

Avantageusement, les zones d'amortissements se présentent sous la forme de languettes élastiques venant en saillie de la face du volet correspondante.Advantageously, the zones of depreciation are in the form of elastic tongues projecting from the face of the corresponding flap.

L'invention sera mieux comprise à l'aide de la description détaillée qui est exposée ci-dessous en regard du dessin annexé dans lequel :

  • La figure 1 est une vue arrière en perspective d'une bouche de ventilation selon l'invention.
  • La figure 2 est une vue partielle du volet de réglage équipant la bouche de ventilation de la figure 1.
  • La figure 3 est en vue en coupe transversale prise selon l'axe III - III montré sur les figures 1 et 2.

  • Les figures 3 et 4 montrent le volet de réglage en position de repos.
  • La figure 5 est une vue en coupe transversale selon le même axe que la figure 3 mais montrant un volet de réglage fermé.
  • La figure 6 est une vue en coupe transversale selon le même axe que la figure 4 mais montrant un volet de réglage en position ouverte.
  • La figure 7 est une vue agrandie arrière du système d'attache du volet de réglage à l'intérieur de la bouche de ventilation.
The invention will be better understood with the aid of the detailed description which is set out below with reference to the appended drawing in which:
  • The figure 1 is a perspective rear view of a ventilation mouth according to the invention.
  • The figure 2 is a partial view of the adjustment flap fitted to the ventilation opening of the figure 1 .
  • The figure 3 is in cross-sectional view along axis III-III shown on the Figures 1 and 2 .
  • The figure 4 is a cross-sectional view along the IV - IV axis shown on the Figures 1 and 2 .
  • The figures 3 and 4 show the adjustment flap in the rest position.
  • The figure 5 is a cross-sectional view along the same axis as the figure 3 but showing a closed adjustment flap.
  • The figure 6 is a cross-sectional view along the same axis as the figure 4 but showing a control flap in the open position.
  • The figure 7 is an enlarged rear view of the fastening system of the adjustment flap inside the ventilation opening.

Une bouche de ventilation 1 auto-réglable telle que représentée sur les figures 1 à 7, comprend un corps formant un conduit 2 présentant une entrée 3 et une sortie 4 séparées l'une de l'autre par une partie centrale logeant un mécanisme de régulation comprenant un volet de régulation 6 séparant la partie centrale en une partie 5b située sur le passage de l'air entre l'entrée 3 et la sortie 4 et un partie 5a située de l'autre côté du volet 6.A self-adjustable ventilation mouth 1 as shown on the Figures 1 to 7 , comprises a body forming a duct 2 having an inlet 3 and an outlet 4 separated from each other by a central part housing a regulation mechanism comprising a regulating flap 6 separating the central part in a part 5b located on the passage of air between the inlet 3 and the outlet 4 and a portion 5a located on the other side of the flap 6.

En fonctionnement, l'air de ventilation pénètre de façon classique dans le conduit 2 par son entrée 3, puis traverse la partie centrale 5b, et enfin s'échappe par la sortie 4 selon un débit régulé. L'air ne passe pratiquement pas par la zone 5a.In operation, the ventilation air enters conventionally into the duct 2 through its inlet 3, then through the central portion 5b, and finally escapes through the outlet 4 at a controlled flow rate. The air hardly passes through zone 5a.

Plus précisément, le volet de régulation 6 est réalisé sous la forme d'un panneau monté pivotant autour d'un pseudo axe A sensiblement transversal par l'intermédiaire d'une liaison déformable.More precisely, the regulation flap 6 is made in the form of a panel pivotally mounted around a substantially transverse axis A pseudo via a deformable connection.

En l'espèce, selon le mode de réalisation représenté, le volet de régulation 6 est fixé dans une paroi 7 supérieure de la bouche de ventilation 1.In this case, according to the embodiment shown, the regulation flap 6 is fixed in an upper wall 7 of the ventilation opening 1.

Le conduit 2 présente également une paroi inférieure ajourée servant ainsi d'entrée d'air 3, une paroi latérale ouverte servant de sortie d'air 4 et une paroi latérale de façade fermée 9.The duct 2 also has a perforated bottom wall thus serving as air inlet 3, an open side wall serving as an air outlet 4 and a closed facade side wall 9.

Ainsi, lorsque la bouche de ventilation 1 est à l'arrêt, le volet de régulation 6 est maintenu dans une position sensiblement verticale. En fonctionnement, la différence de pression de part et d'autre du volet de régulation 6 provoque une déformation pratiquement assimilable à une mise en rotation de ce dernier autour du pseudo l'axe A, comme visible sur les figures 3 à 6.Thus, when the vent 1 is stopped, the control flap 6 is maintained in a substantially vertical position. In operation, the difference in pressure on either side of the regulation flap 6 causes a deformation practically comparable to a rotation of the latter around the pseudo axis A, as visible on the Figures 3 to 6 .

Par ailleurs, la bouche de ventilation 1 comprend une série de renforts 10 présentant sensiblement une forme d'équerre et possédant un premier prolongement 10a fixé dans une paroi inférieure 9 ajourée servant d'entrée d'air 3 et un deuxième prolongement 10b fixé dans la paroi supérieure 7 et s'étendant le long de cette dernière jusqu'au niveau de points d'attache 13 du volet de réglage 6.Furthermore, the ventilation opening 1 comprises a series of reinforcements 10 having substantially a square shape and having a first extension 10a fixed in a perforated bottom wall 9 serving as an air inlet 3 and a second extension 10b fixed in the upper wall 7 and extending along the latter to the level of attachment points 13 of the adjustment flap 6.

Ces renforts 10 servent, d'une part, à assurer et maintenir un écartement constant entre la paroi inférieure et la paroi supérieure et à renforcer la structure de la bouche de ventilation 1 au niveau de points d'attache 13du volet de régulation 6, endroits où la paroi supérieure est le plus sollicité mécaniquement.These reinforcements 10 serve, on the one hand, to ensure and maintain a constant separation between the bottom wall and the upper wall and to reinforce the structure of the ventilation opening 1 at the points of attachment 13 of the regulation flap 6, locations where the upper wall is the most mechanically stressed.

Le volet de régulation 6 est réalisé dans un matériau souple par moulage et présente au niveau de chaque point d'attache 13 une languette 12 souple.The regulation flap 6 is made of a flexible material by molding and has at each attachment point 13 a flexible tongue 12.

Les languettes 12 souples permettent le quasi pivotement du volet de régulation 6 autour d'un axe sensiblement longitudinal par simple flexion de la languette 12.The flexible tongues 12 allow the quasi-pivoting of the regulation flap 6 about a substantially longitudinal axis by simply bending the tongue 12.

Toutefois, les languettes étant réalisées dans un matériau souple de type élastomère, la languette 12, lorsque fléchie et écartée de sa position de repos, génère une force de retour élastique s'opposant à ladite flexion.However, the tongues being made of a flexible elastomer material, the tongue 12, when flexed and spaced from its rest position, generates an elastic return force opposing said bending.

Cette force de retour élastique étant plus grande avec la flexion subie, les mouvements intempestifs de pivotement du volet de régulation, s'en trouvent amortis.This elastic return force being greater with the bending undergone, inadvertent pivoting movements of the control flap, are damped.

Un second amortissement peut-être rendu nécessaire pour éviter des chocs bruyants du volet de régulation 6 contre les renforts 10 d'une part, et contre l'entrée d'air 3, d'autre part.A second damping may be necessary to avoid noisy shocks of the control flap 6 against the reinforcements 10 on the one hand, and against the air inlet 3, on the other hand.

Pour ce faire, le volet de régulation présente des zones d'amortissement se présentant sous la forme de languettes 15 élastiques venant en saillie du volet de régulation 6 sur une face correspondante.To do this, the control flap has damping zones in the form of resilient tongues protruding from the regulating flap 6 on a corresponding face.

Ces languettes 15 sont disposées en regard des zones éventuelles de choc et viennent remplir un rôle de ressort souple lorsque le volet de régulation 6 vient en butée contre un des obstacles mentionnés.These tongues 15 are arranged facing possible areas of shock and come to play a role of flexible spring when the control flap 6 abuts against one of the obstacles mentioned.

Bien que l'invention ait été décrite en liaison avec des exemples particuliers de réalisation, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention. Des contrepoids ou ressorts pourront notamment être rajoutés pour permettre une utilisation de la bouche de ventilation selon d'autres direction.Although the invention has been described in connection with particular embodiments, it is obvious that it is not limited thereto and that it comprises all the technical equivalents of the means described and their combinations if they are within the scope of the invention. Counterweights or springs may in particular be added to allow use of the ventilation opening in other directions.
