COM PORTANT U N E SOU RCE LU M I N EUS E  COMBUSTIO N A U N E V E R E M E N EUS
La présente invention concerne de manière générale un suceur d'aspirateur destiné à équiper un aspirateur. The present invention generally relates to a vacuum nozzle for fitting a vacuum cleaner.
Il est connu dans l'art antérieur des suceurs d'aspirateurs équipés de sources lumineuses sur un bord d'attaque du suceur d'aspirateur, pour fournir un éclairage du sol à nettoyer situé devant le bord d'attaque. Deux inconvénients sont associés à ces suceurs d'aspirateur. Un premier inconvénient est qu'il faut prévoir plusieurs sources lumineuses pour correctement éclairer le sol à nettoyer. Les coûts associés à cette option d'éclairage en sont d'autant plus élevés. Un deuxième inconvénient est que ces sources lumineuses sont exposées aux chocs, et risquent donc d'être cassées, ce qui impose de les protéger avec une paroi transparente, qui augmente encore le coût. It is known in the prior art suction nozzles equipped with light sources on a leading edge of the vacuum nozzle, to provide a lighting of the soil to be cleaned located in front of the leading edge. Two disadvantages are associated with these vacuum suckers. A first drawback is that several light sources must be provided to properly illuminate the floor to be cleaned. The costs associated with this lighting option are all the higher. A second disadvantage is that these light sources are exposed to shocks, and may be broken, which requires to protect them with a transparent wall, which further increases the cost.
Un but de la présente invention est de répondre aux inconvénients des documents de l'art antérieur mentionnés ci-dessus et en particulier, tout d'abord, de proposer un suceur d'aspirateur agencé pour éclairer un sol à nettoyer, tout en étant bon marché à produire. An object of the present invention is to meet the disadvantages of the documents of the prior art mentioned above and in particular, first of all, to propose a vacuum nozzle arranged to illuminate a floor to be cleaned, while being good market to produce.
Pour cela un premier aspect de l'invention concerne un suceur d'aspirateur comprenant : For this a first aspect of the invention relates to a vacuum nozzle comprising:
- un corps de suceur avec au moins un bord d'attaque, a nozzle body with at least one leading edge,
- au moins une source lumineuse agencée pour émettre de la lumière, at least one light source arranged to emit light,
- au moins une surface de projection agencée sur ledit au moins un bord d'attaque, pour recevoir la lumière émise par ladite au moins une source lumineuse et projeter un faisceau lumineux d'éclairage d'un sol à nettoyer, caractérisé en ce que ladite au moins une surface de projection est agencée le long dudit au moins un bord d'attaque et en ce que le suceur d'aspirateur comprend des moyens de transmission agencés entre ladite au moins une source lumineuse et ladite au moins une surface de projection, pour transmettre et distribuer la lumière émise par ladite au moins une source lumineuse le long de ladite au moins une surface de projection. Le suceur d'aspirateur selon la mise en œuvre ci-dessus ne nécessite qu'une source lumineuse pour obtenir un faisceau lumineux distribué tout le long du bord d'attaque. La fonction d'éclairage est donc réalisée avec une seule source lumineuse, ce qui limite son coût, sans pour autant diminuer l'efficacité de l'éclairage. De plus, les moyens de transmission offrent la possibilité de déporter la source lumineuse à distance du bord d'attaque, ce qui limite les risques de chocs et de casse. at least one projection surface arranged on said at least one leading edge, for receiving the light emitted by said at least one light source and projecting a lighting light beam of a floor to be cleaned, characterized in that said at least one projection surface is arranged along said at least one leading edge and in that the vacuum nozzle comprises transmission means arranged between said at least one light source and said at least one projection surface, for transmitting and distributing the light emitted by said at least one light source along said at least one projection surface. The vacuum cleaner according to the implementation above requires only a light source to obtain a light beam distributed along the leading edge. The lighting function is therefore performed with a single light source, which limits its cost, without reducing the efficiency of the lighting. In addition, the transmission means provide the possibility of moving the light source away from the leading edge, which limits the risk of shock and breakage.
Selon un mode de réalisation, le suceur d'aspirateur comprend une coque extérieure formant le corps, et ladite au moins une source lumineuse est agencée à l'intérieur de la coque. La source lumineuse, ainsi déportée à l'intérieur de la coque du suceur d'aspirateur grâce aux moyens de transmission, est correctement protégée. According to one embodiment, the vacuum nozzle comprises an outer shell forming the body, and said at least one light source is arranged inside the shell. The light source, thus remote inside the hull of the suction nozzle through the transmission means, is properly protected.
Selon un mode de réalisation, les moyens de transmission comprennent au moins un guide de lumière en matière transparente, et ladite au moins une surface de projection est une surface latérale dudit au moins un guide de lumière. Le coût du suceur d'aspirateur est réduit en cumulant sur le même composant (le guide de lumière) la fonction de transmission, et la fonction de projection de la lumière. According to one embodiment, the transmission means comprise at least one light guide of transparent material, and said at least one projection surface is a lateral surface of said at least one light guide. The cost of the vacuum nozzle is reduced by accumulating on the same component (the light guide) the transmission function, and the projection function of the light.
Selon un mode de réalisation, ledit au moins un guide de lumière comprend une face opposée à ladite au moins une surface de projection, et la face opposée comprend des moyens de distribution de la lumière, agencés pour distribuer la lumière le long de ladite au moins une surface de projection. Les moyens de distribution de la lumière le long de la surface de projection sont directement intégrés au guide de lumière, ce qui évite de modifier le reste du suceur d'aspirateur pour obtenir ce résultat technique. Selon un mode de réalisation, les moyens de distribution comprennent une pluralité de surfaces au moins partiellement réfléchissantes agencées le long de la face opposée et agencées pour chacune réfléchir une partie de la lumière émise vers ladite au moins une surface de projection. Selon un mode de réalisation, ledit au moins un guide de lumière présente une section transversale de passage de la lumière, ladite au moins une source lumineuse est agencée à une extrémité dudit au moins un guide de lumière, la section transversale au niveau d'une première surface au moins partiellement réfléchissante est supérieure à la section transversale au niveau d'une deuxième surface au moins partiellement réfléchissante, la première surface étant agencée entre ladite au moins une source lumineuse et la deuxième surface. Chaque surface au moins partiellement réfléchissante reçoit une partie de la lumière émise, grâce à la réduction de la section transversale au droit de chaque surface réfléchissante, à mesure que l'on s'éloigne de la source lumineuse. According to one embodiment, said at least one light guide comprises a face opposite to said at least one projection surface, and the opposite face comprises light distribution means, arranged to distribute the light along said at least one a projection surface. The light distribution means along the projection surface are directly integrated with the light guide, which avoids modifying the rest of the vacuum nozzle to obtain this technical result. According to one embodiment, the distribution means comprise a plurality of at least partially reflecting surfaces arranged along the opposite face and arranged to each reflect a portion of the light emitted towards said at least one projection surface. According to one embodiment, said at least one light guide has a cross section for passing light, said at least one light source is arranged at one end of said at least one light guide, the cross section at a first at least partially reflecting surface is greater than the cross section at a second at least partially reflective surface, the first surface being arranged between said at least one light source and the second surface. Each at least partially reflective surface receives a portion of the emitted light, by reducing the cross section to the right of each reflecting surface as one moves away from the light source.
Selon un mode de réalisation, la section transversale est décroissante depuis l'extrémité où est agencée ladite au moins une source lumineuse. According to one embodiment, the cross section is decreasing from the end where is arranged said at least one light source.
Selon un mode de réalisation, les moyens de distribution consistent en des stries successives, chaque strie présente deux faces formant un angle entre elles, partant de la face opposée et se rejoignant pour former un creux. Cette mise en œuvre est économique. According to one embodiment, the distribution means consist of successive streaks, each streak has two faces forming an angle between them, starting from the opposite face and joining to form a hollow. This implementation is economical.
Selon un mode de réalisation, la distance entre ladite au moins une surface de projection et le creux d'une première strie est supérieure à la distance entre ladite au moins une surface de projection et le creux d'une deuxième strie, la première strie étant agencée entre ladite au moins une source lumineuse et la deuxième strie. Cet agencement contribue à obtenir une diffusion homogène de la lumière le long du guide de lumière. According to one embodiment, the distance between said at least one projection surface and the hollow of a first strip is greater than the distance between said at least one projection surface and the hollow of a second strip, the first strip being arranged between said at least one light source and the second streak. This arrangement contributes to a homogeneous diffusion of light along the light guide.
Selon un mode de réalisation, l'angle entre les deux faces de la première strie est inférieur à l'angle entre les deux faces de la deuxième strie. Cet agencement contribue à obtenir une diffusion homogène de la lumière le long du guide de lumière. According to one embodiment, the angle between the two faces of the first groove is less than the angle between the two faces of the second groove. This arrangement contributes to a homogeneous diffusion of light along the light guide.
Selon un mode de réalisation, le creux est de forme arrondie. Cet agencement contribue à obtenir une diffusion homogène de la lumière le long du guide de lumière. According to one embodiment, the hollow is of rounded shape. This arrangement contributes to a homogeneous diffusion of light along the light guide.
Selon un mode de réalisation, ledit au moins un guide de lumière est encastré dans une rainure du corps, et la rainure présente au moins une surface réfléchissante de la lumière. Cette mise en œuvre permet d'augmenter l'efficacité de la transmission, car la lumière qui sort par une autre face que la surface de projection est réfléchie vers le guide de lumière. Idéalement, toutes les surfaces de la rainure en regard du guide de lumière sont réfléchissantes. On peut envisager de colorer ces surfaces de la rainure en blanc, pour les rendre réfléchissantes. According to one embodiment, said at least one light guide is embedded in a groove of the body, and the groove has at least one reflective surface of the light. This implementation makes it possible to increase the efficiency of the transmission, because the light coming out from another face than the projection surface is reflected towards the light guide. Ideally, all the surfaces of the groove facing the light guide are reflective. It is possible to color these surfaces of the groove in white, to make them reflective.
Selon un mode de réalisation, ledit au moins un guide de lumière est en polycarbonate présentant une transmittance supérieure à 85% pour une épaisseur de 4 millimètres, pour des ondes de longueur d'onde allant de 400 nanomètres à 800 nanomètres. According to one embodiment, said at least one light guide is made of polycarbonate having a transmittance greater than 85% for a thickness of 4 millimeters, for wavelength waves ranging from 400 nanometers to 800 nanometers.
Selon un mode de réalisation, ladite au moins une surface de projection est dépolie. Selon un mode de réalisation, ledit au moins un guide de lumière comprend une lentille agencée pour projeter l'image de ladite au moins une source lumineuse à l'infini, dans une direction longitudinale dudit au moins un guide de lumière. According to one embodiment, said at least one projection surface is frosted. According to one embodiment, said at least one light guide comprises a lens arranged to project the image of said at least one light source at infinity, in a longitudinal direction of said at least one light guide.
Selon un mode de réalisation : According to one embodiment:
- le corps présente une forme triangulaire avec deux bords d'attaque agencés en pointe vers l'avant et reliés entre eux à l'arrière par une face arrière,the body has a triangular shape with two leading edges arranged in a point towards the front and connected to each other at the rear by a rear face,
- le suceur d'aspirateur comprend deux sources lumineuses chacune agencée dans une partie arrière d'un bord d'attaque, the suction nozzle comprises two light sources each arranged in a rear part of a leading edge,
- les moyens de transmission comprennent deux guides de lumière agencés chacun le long d'un bord d'attaque, the transmission means comprise two arranged light guides each along a leading edge,
- et le suceur d'aspirateur comprend une pièce de liaison transparente agencée pour relier entre eux les deux guides de lumière à la pointe du suceur d'aspirateur. Selon un mode de réalisation, ladite au moins une source lumineuse est une diode électroluminescente.  and the suction nozzle comprises a transparent connecting piece arranged to connect the two light guides to one another at the tip of the vacuum nozzle. According to one embodiment, said at least one light source is a light emitting diode.
Un second aspect de l'invention est un aspirateur comprenant un suceur d'aspirateur selon le premier aspect de l'invention. A second aspect of the invention is a vacuum cleaner comprising a vacuum cleaner according to the first aspect of the invention.
D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée qui suit d'un mode de réalisation de l'invention donné à titre d'exemple nullement limitatif et illustré par les dessins annexés, dans lesquels : Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawings, in which:
- la figure 1 représente une vue en perspective d'un suceur d'aspirateur selon l'invention ; - la figure 2 représente un guide de lumière du suceur d'aspirateur de la figure 1 ; - Figure 1 shows a perspective view of a vacuum nozzle according to the invention; FIG. 2 represents a light guide of the vacuum nozzle of FIG. 1;
- la figure 3 représente une partie du guide de lumière de la figure 2 ; - Figure 3 shows a portion of the light guide of Figure 2;
- la figure 4 représente une autre partie du guide de lumière de la figure 2. La figure 1 représente un suceur d'aspirateur de forme triangulaire. Il comprend un bord d'attaque gauche 30 et un bord d'attaque droit 35 qui se rejoignent vers l'avant pour former une pointe 50. A l'arrière, les bords d'attaque 30 et 35 sont reliés par une face arrière 40. Par ailleurs, le suceur d'aspirateur comprend un raccord 70 pour permettre une connexion avec un conduit d'un aspirateur. - Figure 4 shows another part of the light guide of Figure 2. Figure 1 shows a suction nozzle vacuum triangular shape. It comprises a left leading edge 30 and a right leading edge 35 which join forward to form a tip 50. At the rear, the leading edges 30 and 35 are connected by a rear face 40 In addition, the suction nozzle includes a connector 70 to allow connection with a duct of a vacuum cleaner.
Le suceur d'aspirateur comprend un guide de lumière 10 dont une face extérieure forme une surface de projection 15. Cette surface de projection 15 est agencée pour projeter un faisceau lumineux sur un sol à nettoyer, comme le montrent les flèches représentées. Le faisceau lumineux projeté par la surface de projection 15 est créé par une source lumineuse 60 représentée en traits pointillés, car agencée à l'intérieur de la coque du corps du suceur d'aspirateur. Le guide de lumière 10 recueille à une des ses extrémités la lumière émise par la source lumineuse 60 et transmet cette lumière émise vers la surface de projection 15 sur toute sa longueur, pour obtenir un faisceau lumineux uniformément projeté le long du bord d'attaque 30. En d'autres termes, le guide de lumière 10 est agencé pour obtenir un éclairage et une signalisation homogènes sur sa longueur. Un mode de réalisation préféré pour la source lumineuse consiste en une diode électroluminescente, communément appelée LED. The suction nozzle comprises a light guide 10, an outer face of which forms a projection surface 15. This projection surface 15 is designed to project a light beam onto a floor to be cleaned, such as show the arrows represented. The light beam projected by the projection surface 15 is created by a light source 60 shown in dashed lines, as arranged inside the shell of the body of the vacuum nozzle. The light guide 10 collects at one of its ends the light emitted by the light source 60 and transmits this emitted light to the projection surface 15 over its entire length, to obtain a light beam uniformly projected along the leading edge 30 In other words, the light guide 10 is arranged to obtain illumination and signaling homogeneous along its length. A preferred embodiment for the light source consists of a light emitting diode, commonly called LED.
Le guide de lumière 10 est réalisé en matière transparente. On peut envisager d'utiliser du polycarbonate, et en particulier un polycarbonate ayant une transmittance élevée pour les ondes lumineuses du domaine visible. Il est avantageux de choisir une transmittance supérieure à 85% pour une épaisseur de 4 millimètres, pour des ondes de longueur d'onde allant de 400 nanomètres à 800 nanomètres. Un tel matériau est disponible chez le fournisseur Bayer sous la référence Makrolon © LED2045 ou Makrolon © LED2245. Le guide de lumière 10 permet de positionner la source lumineuse 60 à l'intérieur de corps du suceur d'aspirateur pour qu'elle soit protégée des chocs, il en résulte une robustesse accrue. De plus, une seule source lumineuse 60 suffit pour projeter un faisceau de lumière homogène tout le long du bord d'attaque 30. II en va de même pour le bord d'attaque opposé 35, non visible sur cette figure. Le suceur comprend également une pièce de liaison transparente 20, qui joint les deux extrémités avant des deux guides de lumière du suceur d'aspirateur. Cette pièce de liaison transparente 20 est également agencée pour projeter de la lumière vers l'avant du suceur d'aspirateur, ce qui améliore l'éclairage. La figure 2 représente une vue du guide de lumière 10. La surface de projection 15 est lisse, et se trouve agencée en regard d'une face opposée 16 qui comporte une pluralité de stries. Une première extrémité, qui comporte un cône 1 1 , est agencée à côté de la source lumineuse 60, le cône 1 1 ayant pour effet de capter la lumière émise, et de la réfléchir vers la deuxième extrémité opposée du guide de lumière 10. The light guide 10 is made of transparent material. It is possible to envisage the use of polycarbonate, and in particular a polycarbonate having a high transmittance for light waves in the visible range. It is advantageous to choose a transmittance greater than 85% for a thickness of 4 millimeters, for wavelength waves ranging from 400 nanometers to 800 nanometers. Such material is available from the Bayer supplier under the reference Makrolon © LED2045 or Makrolon © LED2245. The light guide 10 makes it possible to position the light source 60 inside the body of the suction nozzle so that it is protected against shocks, resulting in increased robustness. In addition, a single light source 60 is sufficient to project a homogeneous light beam all along the leading edge 30. The same goes for the opposite leading edge 35, not visible in this figure. The nozzle also comprises a transparent connecting piece 20, which joins the two front ends of the two light guides of the vacuum nozzle. This transparent connecting piece 20 is also arranged to project light towards the front of the vacuum nozzle, which improves the lighting. Figure 2 shows a view of the light guide 10. The projection surface 15 is smooth, and is arranged facing an opposite face 16 which has a plurality of streaks. A first end, which has a cone January 1, is arranged next to the light source 60, the cone January 1 having the effect of capturing the emitted light, and reflect it towards the opposite second end of the light guide 10.
La pluralité de stries est agencée pour réfléchir la lumière émise par la source lumineuse 60 depuis la face opposée 16 vers la surface de projection 15. La section transversale du guide de lumière 10 est décroissante à mesure que l'on s'éloigne de l'extrémité où est agencée la source lumineuse, de sorte que chaque strie de la face opposée 16 renvoie une partie de la lumière émise, comme le montrent les flèches des rayons lumineux A et B. The plurality of streaks is arranged to reflect the light emitted by the light source 60 from the opposite face 16 to the projection surface 15. The cross section of the light guide 10 is decreasing as one moves away from the end where is arranged the light source, so that each streak of the opposite face 16 returns a portion of the emitted light, as shown by the arrows of light beams A and B.
Afin de masquer l'intérieur du guide de lumière et rendre la projection du faisceau lumineux la plus homogène possible, la surface de projection 15 est dépolie. In order to mask the inside of the light guide and make the projection of the light beam as homogeneous as possible, the projection surface 15 is frosted.
La figure 3 représente une partie centrale du guide de lumière 10. Une première strie 12 est agencée entre la source lumineuse et une deuxième strie 13. La première strie 12 est formée par deux faces formant entre elles un angle α1 , et se rejoignant pour former un creux séparé de la surface de projection 15 d'une distance D1 . La deuxième strie 13 est formée par deux faces formant entre elles un angle a2, et se rejoignant pour former un creux séparé de la surface de projection 15 d'une distance D2. Comme indiqué sur la figure, la distance D1 est supérieure à la distance D2, ce qui garantit que le rayon R2 pourra bien aller se réfléchir sur une des faces formant la strie 13. Comme la première strie 12 réfléchit de son côté le rayon R1 , le faisceau lumineux projeté par la surface de projection 15 est homogène. Afin de renforcer cette projection homogène le long du guide de lumière 10, les creux des stries sont arrondis, pour diffuser la lumière comme représenté par les flèches au niveau du creux de la deuxième strie 13. Un autre moyen d'obtenir un faisceau homogène de lumière le long du guide de lumière 10 est d'augmenter l'angle entre les faces de chaque strie, au fur et à mesure que l'on s'éloigne de la source lumineuse 60. En d'autres termes, l'angle a1 est inférieur à l'angle a2. FIG. 3 shows a central part of the light guide 10. A first strip 12 is arranged between the light source and a second strip 13. The first strip 12 is formed by two faces forming an angle α1 between them, and joining together to form a hollow separated from the projection surface 15 by a distance D1. The second strip 13 is formed by two faces forming an angle α2 between them, and joining to form a hollow separated from the projection surface 15 by a distance D2. As shown in the figure, the distance D1 is greater than the distance D2, which ensures that the radius R2 can be reflected on one of the faces forming the streak 13. As the first stripe 12 reflects on its side the radius R1, the light beam projected by the projection surface 15 is homogeneous. In order to reinforce this homogeneous projection along the light guide 10, the grooves of the grooves are rounded to diffuse the light as represented by the arrows at the level of the hollow of the second groove 13. Another way of obtaining a homogeneous beam of light along the light guide 10 is to increase the angle between the faces of each streak, as one moves away from the light source 60. In other words, the angle a1 is less than the angle a2.
Enfin, le guide de lumière 10 est agencé dans une rainure du corps de suceur d'aspirateur, et la face opposée 16 est agencée en regard d'une face de la rainure. Afin d'améliorer l'efficacité de l'éclairage, la face de la rainure en regard de la face opposée est blanche ou réfléchissante, afin de renvoyer vers le guide de lumière 10 des rayons lumineux qui seraient diffractés ou transmis par les stries vers la rainure. La figure 4 représente l'extrémité du guide de lumière agencée en regard de la source lumineuse 60. Cette extrémité est chargée de capter la lumière émise par la source lumineuse 60, pour l'envoyer dans le guide de lumière 10. A cet effet, le cône 1 1 est agencé pour réfléchir la lumière émise vers le guide de lumière 10, et un deuxième cône 14 est agencé pour centrer et canaliser la lumière émise vers le guide de lumière 10. Cette extrémité du guide de lumière 10 est agencée pour créer à partir de la lumière émise par la source lumineuse 60 un faisceau de lumière parallèle à la surface de projection 15, à l'intérieur du guide de lumière 10. L'image de la source lumineuse 60 est projetée à l'infini. On comprendra que diverses modifications et/ou améliorations évidentes pour l'homme du métier peuvent être apportées au mode de réalisation de l'invention décrit dans la présente description sans sortir du cadre de l'invention défini par les revendications annexées. Finally, the light guide 10 is arranged in a groove of the suction nozzle body, and the opposite face 16 is arranged opposite one face of the groove. In order to improve the efficiency of the illumination, the face of the groove opposite the opposite face is white or reflecting, in order to return towards the light guide 10 light rays which would be diffracted or transmitted by the streaks towards the groove. FIG. 4 represents the end of the light guide arranged opposite the light source 60. This end is responsible for capturing the light emitted by the light source 60, to send it into the light guide 10. For this purpose, the cone 11 is arranged to reflect the light emitted towards the light guide 10, and a second cone 14 is arranged to center and channel the light emitted towards the light guide 10. This end of the light guide 10 is arranged to create from the light emitted by the light source 60 a light beam parallel to the projection surface 15, inside the light guide 10. The image of the light source 60 is projected to infinity. It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the embodiment of the invention described in the present description without departing from the scope of the invention defined by the appended claims.
