Description
L'invention concerne un indicateur visuel de la puissance d'aspiration d'un aspirateur au moyen d'un conducteur de lumière.The invention relates to a visual indicator of the suction power of a vacuum cleaner by means of a light conductor.
La plupart des aspirateurs disponibles sur le marché présentent aujourd'hui des moyens de réguler la puissance d'aspiration au moyen d'ouvertures réglables. Ces ouvertures sont usuellement positionnées au sommet du tube d'aspiration ou sur la crosse de l'aspirateur pour être facilement actionnées par les utilisateurs.Most vacuums available on the market nowadays have means of regulating the suction power by means of adjustable openings. These openings are usually positioned at the top of the suction tube or on the butt of the vacuum cleaner to be easily operated by the users.
Il est en effet utile dans de nombreuses situations d'utiliser l'aspirateur avec une puissance d'aspiration réduite, notamment pour nettoyer des objets légers susceptibles d'être entraînés dans l'appareil, des voilages, des tissus et d'autres éléments souples pouvant obturer le conduit et bloquer l'activité de nettoyage.It is indeed useful in many situations to use the vacuum cleaner with reduced suction power, in particular for cleaning light objects that may be entrained in the apparatus, curtains, fabrics and other flexible elements. can block the duct and block the cleaning activity.
La réduction de la puissance d'aspiration est obtenue de différentes manières, par exemple avec un moteur à puissance variable, mais aussi le plus souvent, et même parfois de manière complémentaire au moteur à puissance variable, au moyen d'ouvertures positionnées sur le circuit d'air d'aspiration comme le décrit par exemple le document
De manière classique ces ouvertures actionnables manuellement sont obturées par des trappes coulissantes qui ne comportent aucune indication du niveau de puissance d'aspiration ce qui représente un inconvénient pour les utilisateurs.Conventionally these manually operable openings are closed by sliding doors that have no indication of the suction power level which is a disadvantage for users.
Conscients de ce problème divers constructeurs ont positionné des indicateurs du débit d'air sur le corps de l'aspirateur sous forme de dispositifs d'affichage. Certains de ces indicateurs comportent des diodes lumineuses et des circuits électroniques pour le traitement et la transmission de l'information vers l'afficheur.Conscious of this problem various manufacturers have positioned airflow indicators on the body of the vacuum cleaner in the form of display devices. Some of these indicators include LEDs and electronic circuits for the processing and transmission of information to the display.
Pour les afficheurs, il a parfois été utilisé des dispositifs permettant de guider la lumière, par exemple sous forme de fibres optiques ou de moyens de réflexions optiques, ces afficheurs comportant une source lumineuse électrique de type diode électroluminescente pour l'indication de la puissance d'aspiration.For displays, it has sometimes been used devices to guide the light, for example in the form of optical fibers or optical reflective means, these displays comprising an electroluminescent light-emitting type light source for the indication of the suction power.
Ces indicateurs de puissance d'aspiration des aspirateurs comportant des circuits électroniques et des diodes présentent le double inconvénient d'être coûteux et d'être relativement fragiles, notamment quand les utilisateurs manipulent souvent les aspirateurs avec vigueur et que l'appareil reçoit de nombreux chocs, qui risquent de rompre les connexions électriques.These vacuum suction power indicators comprising electronic circuits and diodes have the double disadvantage of being expensive and relatively fragile, especially when users often handle the vacuums vigorously and the apparatus receives many shocks. , which may break the electrical connections.
L'invention a donc pour objectif de résoudre ces principales difficultés en proposant un indicateur de puissance d'aspiration très simple, ne disposant pas de diode(s) ou d'éléments électroniques, ni même de source d'énergie pour fonctionner, donc très peu coûteux à la fabrication et à l'utilisation et d'une grande fiabilité.The invention therefore aims to solve these major difficulties by providing a very simple suction power indicator, having no diode (s) or electronic elements, or even a source of energy to operate, so very inexpensive to manufacture and use and highly reliable.
Un autre but de l'invention est la réalisation d'un dispositif de modification de la puissance d'aspiration par une fuite d'air qui soit silencieux.Another object of the invention is to provide a device for modifying the suction power by an air leak which is silent.
Selon l'invention, l'indicateur visuel de la puissance d'aspiration d'un aspirateur est porté par un organe de commande, lequel organe de commande permettant de régler le débit de fuite d'air d'aspiration est contenu dans un boîtier positionné sur la crosse de l'aspirateur. Ledit indicateur visuel étant caractérisé :
- par le fait qu'il est constitué d'un élément plastique conducteur de lumière conformé pour renvoyer la lumière vers sa face supérieure, en des positions privilégiées,
- par le fait que l'élément plastique est en regard d'une fenêtre aménagée dans la partie supérieure du boîtier,
- par le fait qu'il est en mouvement relatif par rapport à la fenêtre lorsqu'un volet coulissant, contrôlant le débit de la fuite d'air d'aspiration est actionné par l'organe de commande, de manière à indiquer le niveau d'aspiration par la partie visible de l'élément plastique.
- in that it consists of a plastic light-conducting element shaped to send the light back to its upper face, in privileged positions,
- in that the plastic element is opposite a window fitted in the upper part of the housing,
- in that it is in relative motion with respect to the window when a sliding shutter, controlling the flow of the suction air leak is actuated by the control member, so as to indicate the level of suction by the visible part of the plastic element.
Les avantages de l'indicateur de puissance d'aspiration par conducteur de lumière sont multiples, les plus importants étant l'extrême simplicité du dispositif et le coût très bas de fabrication. L'esthétique de l'élément et sa grande robustesse sont également intéressantes.The advantages of the light conductor suction power indicator are multiple, the most important being the extreme simplicity of the device and the very low cost of manufacture. The aesthetics of the element and its robustness are also interesting.
Selon un mode préféré de mise en oeuvre de l'invention, l'élément plastique est solidaire du volet coulissant contrôlant le débit de fuite d'air d'aspiration, la fenêtre étant immobile.According to a preferred embodiment of the invention, the plastic element is integral with the sliding shutter controlling the suction air leakage rate, the window being stationary.
D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifs.

Comme le montre la
Tel que cela est illustré sur la
De manière classique le contrôle de la fuite d'air d'aspiration est réalisé au moyen d'un volet 8 coulissant incorporé dans le boîtier 4 et disposé entre des ouvertures 9 du boîtier et une ouverture ménagée dans le tube. 3, sensiblement en regard des ouvertures 9. Ledit boîtier est enchâssé au sommet du tube d'aspiration sur la crosse de l'aspirateur.In a conventional manner the control of the suction air leakage is achieved by means of a sliding
Plus précisément le boîtier 4 est fixé sur le tube de l'aspirateur et sur la crosse par des clips, ledit boîtier contient l'organe de commande 5 guidé pour son coulissement par les rails 6. Comme le montre la
Le bouton de commande 10 est ainsi disposé, sur le dessus du boîtier 4, dans les rails 6, par clipage. Il comporte des ergots 101 entrant en prise, au delà des rails 6, avec des gorges complémentaires 81 ménagés dans le volet 8, tel qu'il est bien visible
Par la suite, une mousse 7 est située sur le trajet aéraulique, entre les ouvertures 9 et l'ouverture du tube 3.Subsequently, a
Ainsi, le volet 8 de l'organe de commande, lorsque celui-ci est en position de fermeture, recouvre totalement la mousse 7, interdisant toute entrée d'air dans le conduit d'aspiration. Lorsque l'organe de commande 5 est en position d'ouverture, le volet 8 est retiré et la mousse se trouve positionnée directement sous les ouvertures 9, permettant le passage de l'air de fuite.Thus, the
La mousse 7 permet de diminuer les sifflements occasionnés par l'aspiration de l'air au travers des ouvertures 9 lorsque le volet 8 est en position d'ouverture ou en position intermédiaire. Un effort a en effet été apporté pour réduire le bruit occasionné par le passage de l'air de fuite, non seulement par la présence de la mousse 7, mais également par la présence des multiples ouvertures 9, et leur étendue, cette répartition de l'air dans les ouvertures contribuant également à réduire le bruit.The
Le débit d'air de fuite modifiant la puissance d'aspiration de l'aspirateur est régulé au moyen du bouton de commande 10 actionné par le pouce de l'utilisateur, lequel bouton est solidaire du volet 8 dans l'organe de commande 5, comme cela est illustré sur les
Lorsque le bouton de commande 10 est reculé au maximum, c'est-à-dire dans la position de la
Lorsque le bouton de commande 10 est avancé au maximum, c'est à dire dans la position de la
Il est entendu que cette modification ponctuelle de la puissance d'aspiration peut venir en complément d'un dispositif plus complexe de modification de la puissance par la modulation de la vitesse de rotation du moteur.It is understood that this occasional modification of the suction power can come in addition to a more complex device for modifying the power by modulating the speed of rotation of the motor.
Selon l'invention, l'indicateur de puissance d'aspiration qui permet de situer le débit de fuite d'air est formé par un conducteur de lumière 11 placé à la partie supérieure de l'organe de commande 5.According to the invention, the suction power indicator which makes it possible to locate the air leakage rate is formed by a
Ledit conducteur de lumière 11 se présente sous l'aspect d'une lamelle, pouvant être droite ou légèrement courbée, de forme rectangulaire et disposant éventuellement de moyens de fixation sur l'organe de commande, tel un clip 111 coopérant avec une forme complémentaire du volet 8. Ce dernier comporte une ouverture 82 de taille légèrement plus petite que la taille du conducteur de lumière 11, de sorte que ce dernier prend appui, par son pourtour, sur les bords de l'ouverture 82.Said
La
Ainsi, selon le mode préféré de mise en oeuvre de l'invention, la face de dessus, visible par l'utilisateur, est plane, alors que celle de dessous, en regard du tube d'aspiration, comporte des reliefs 13 pour renvoyer la lumière.Thus, according to the preferred embodiment of the invention, the top face, visible by the user, is flat, while that from below, facing the suction tube, has
En effet, lors de la fabrication de la lamelle constitutive du conducteur de lumière 11, il est aménagé des reliefs 13 correspondant à des évidements de section triangulaire réalisés dans la face inférieure du conducteur de lumière 11, lesquels évidements forment des facettes 16 visibles
Avantageusement, des reliefs sont également réalisés sur la tranche du conducteur de lumière, sur la totalité de son périmètre, ainsi que sur des lignes parallèles au petit côté de la lamelle formant le conducteur de lumière 11, de manière à délimiter des intervalles de puissance d'aspiration.Advantageously, reliefs are also produced on the edge of the light conductor, over its entire perimeter, as well as on lines parallel to the short side of the lamella forming the
Ces reliefs 13, visibles sur la vue en coupe de la
Ainsi, la lumière se propageant dans la lamelle 11 va préférentiellement « sortir » de cette lamelle lors de sa réflexion sur les facettes inclinées 16 des reliefs 13, comme l'indiquent les exemples de propagation de la lumière illustrant la
La
Un détail 14 de la vue en coupe montre le placement du conducteur de lumière 11 sur l'organe de commande 5 et notamment le fait qu'il est aménagé un espace libre 15 sous le conducteur de lumière 11 entre la face inférieure comportant des reliefs 13 et la partie correspondante de l'élément portant le volet 8 coulissant.A
Cet espace libre 15 permet de renvoyer une partie de la lumière dans le conducteur, de manière à optimiser la réflexion des ondes lumineuses vers l'extérieur.This
La lumière concentrée dans les zones des facettes 16 se présente pour l'utilisateur sous forme de barres transversales plus intenses par rapport au reste du conducteur de lumière, ces barres lumineuses matérialisant la puissance d'aspiration.The light concentrated in the areas of the
Il peut en fait être envisagé de multiples moyens de visualisation du niveau de puissance d'aspiration en réalisant des modifications de la surface du conducteur de lumière, par exemple par gravure au laser ou lors de la formation du plastique au moulage.In fact, it is possible to envisage multiple means for visualizing the level of suction power by making modifications of the surface of the light conductor, for example by laser etching or during the formation of plastic molding.
De manière générale, un relief approprié pratiqué sur la surface inférieure du conducteur de lumière permet de réfléchir celle-ci et cette réflexion est plus efficace si elle se produit au niveau d'une interface entre l'air et le plastique conducteur de lumière plutôt qu'entre le conducteur de lumière et un autre plastique.In general, a suitable relief on the lower surface of the light conductor reflects the latter and this reflection is more effective if it occurs at an interface between the air and the light-conducting plastic rather than 'between the light conductor and another plastic.
Pour que la réflexion de la lumière en provenance du conducteur de lumière 11 vers l'utilisateur de l'aspirateur soit maximale il a été trouvé que les reliefs 13 doivent comporter de préférence des facettes inclinées à 45° par rapport à la verticale, c'est-à-dire par rapport à la direction perpendiculaire aux grandes faces du conducteur de lumière, les reliefs 13 étant situés sur la face inférieure de ladite lamelle conductrice de lumière.So that the reflection of the light from the
Tel qu'il est bien visible sur la
Selon l'invention la lumière servant à l'indication de la puissance d'aspiration est la lumière naturelle pour l'affichage de la puissance d'aspiration, cette lumière irradiant la face supérieure du conducteur de lumière. Ceci évite ainsi un dispositif spécifique coûteux à l'aide d'une diode et de son dispositif de commande et d'alimentation.According to the invention, the light serving to indicate the suction power is the natural light for displaying the suction power, this light radiating the upper face of the light conductor. This avoids a costly specific device using a diode and its control device and power supply.
Le boîtier 4, le volet 8 et le bouton de commande 10 sont fabriqués en plastique moulé, rigide et léger.The
Le conducteur de lumière 11 est un polymère spécifique pour cette application. De tels plastiques sont fabriqués par exemple par la société Bayer et mis en forme de manière connue dans des domaines pour l'obtention de fibres optiques et de produits divers.The
En fonctionnement, lorsque l'utilisateur déplace le bouton 10 depuis la position ouverte représentée sur la
Selon une mise en oeuvre préférée de l'invention, un index de type « min / max » est disposé au niveau du guide de lumière, sur le boîtier 4, afin que l'utilisateur repère facilement l'ouverture de la fuite.According to a preferred embodiment of the invention, a "min / max" type index is arranged at the level of the light guide, on the
Afin de guider davantage l'utilisateur dans le réglage approprié de la fuite d'air selon le sol à nettoyer, il peut être prévu de rendre le bouton de commande 10 transparent et de disposer, sur le boîtier 4, entre les rails 6, c'est-à-dire dans la zone de coulissement du bouton 10, des pictogrammes faisant apparaître différentes surfaces et judicieusement positionnées pour que l'utilisateur, en disposant le bouton 10 en regard du pictogramme, réalise ou non une fuite d'air appropriée pour le sol à nettoyer. Par exemple, il peut être disposer les trois pictogrammes suivants :
- un pictogramme figurant des voilages ou rideaux situé en butée du bouton de commande 10 vers la droite selon la
figure 2 et correspondant à une fuite maximale, - un pictogramme figurant un sol lisse sensiblement au milieu du coulissement du bouton de commande 10 et correspondant à une fuite d'air significative,
- un pictogramme figurant une moquette ou un tapis, et situé en butée du bouton de commande 10 vers la gauche selon la
figure 2 et correspondant à une fermeture de la fuite d'air.
- a pictogram depicting curtains or curtains located at the stop of the
control knob 10 to the right according to thefigure 2 and corresponding to a maximum leak, - a pictogram showing a smooth floor substantially in the middle of the sliding of the
control knob 10 and corresponding to a significant air leak, - a pictogram showing a carpet or carpet, and located at the stop of the
control knob 10 to the left according to thefigure 2 and corresponding to a closure of the air leak.
De tels pictogrammes sont illustrés sur la
De nombreuses autres variantes sont possibles pour l'indicateur de puissance d'aspiration par conducteur de lumière sans sortir du cadre de l'invention. Il peut par exemple être envisagé d'autres formes de lamelles et différentes épaisseurs, les facettes destinées à renvoyer la lumière peuvent être plus ou moins nombreuses et plus ou moins larges et espacées, les inclinaisons des facettes peuvent être diversement choisies.Many other variants are possible for the indicator of suction power by light conductor without departing from the scope of the invention. It may for example be envisaged other lamella shapes and different thicknesses, the facets for returning the light may be more or less numerous and more or less wide and spaced, the inclinations of the facets may be variously chosen.
Il peut par ailleurs être imaginé d'imprimer des indications sur la face supérieure des lamelles ou même de graver, sur la face inférieure, des chiffres indicateurs du niveau d'aspiration, lesquels chiffres gravés étant alors lumineux également. En variante ou en complément, des lettres, et/ou des sigles, et/ou des pictogrammes représentant les différents types de sol à nettoyer peuvent être envisagés sans sortir du cadre de la présente invention.It can also be imagined to print indications on the upper face of the slats or even to engrave, on the lower face, figures indicating the level of suction, which engraved numbers are then also bright. Alternatively or additionally, letters, and / or acronyms, and / or pictograms representing the different types of soil to be cleaned can be envisaged without departing from the scope of the present invention.
Le conducteur de lumière est de préférence teinté et il peut être envisagé différentes colorations selon le code que l'on souhaite adopter vis-à-vis de l'utilisateur de l'aspirateur, du vert ou du rouge par exemple.The light conductor is preferably tinted and it can be considered different colorations according to the code that is desired to adopt vis-à-vis the user of the vacuum cleaner, green or red, for example.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation d'écrits et représentés à titre d'exemple, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons.Of course, the invention is not limited to the embodiments of writings and represented by way of example, but it also includes all the technical equivalents and their combinations.
Il peut notamment être envisagé de rendre l'élément plastique 11, non pas solidaire du volet coulissant, mais fixe, la fenêtre étant alors liée au volet coulissant. Le mouvement relatif de la pièce plastique par rapport à la fenêtre est alors réalisé par un déplacement de la fenêtre au-dessus de l'indicateur, qui reste fixe.It may in particular be considered to make the
Par ailleurs, le coulissement, illustré en translation selon l'exemple proposé, peut également être mis en oeuvre en rotation, à l'aide d'une commande appropriée. Si l'on se base sur l'exemple illustrant l'invention, le bouton 10 peut ainsi être prévu pour coulisser sur des rails courbe transversaux, le volet coulissant 8 reprenant la forme courbe du tube en constituant un secteur venant couvrir ou découvrir progressivement l'élément plastique conducteur de lumière selon la rotation du bouton de commande.Furthermore, the sliding, illustrated in translation according to the proposed example, can also be implemented in rotation, with the aid of an appropriate command. Based on the example illustrating the invention, the
