Description

EMBOUT POUR ASPIRATEUR NOZZLE FOR VACUUM CLEANER
La présente invention a pour objet un embout pour aspirateur. Un embout pour aspirateur comporte une platine dont la face inférieure, destinée à prendre appui sur le sol, est éventuellement équipée d'éléments tels que des brosses et comporte éventuellement des canaux dirigeant l'air aspiré vers un orifice d'aspiration. La face supérieure de la platine est équipée d'un tube communiquant avec l'orifice d'aspiration et relié à un groupe d'aspiration situé à proximité du tube ou à distance de celui-ci dans le cas d'une installation avec un groupe centralisé d'aspiration. Les éléments en forme de brosses peuvent être escamotables pour faciliter le déplacement de l'embout sur certains types de sol, notamment des moquettes et des tapis.The present invention relates to a nozzle for a vacuum cleaner. A nozzle for a vacuum cleaner comprises a plate, the lower face of which, intended to bear on the ground, is optionally equipped with elements such as brushes and optionally comprises channels directing the air sucked in towards a suction orifice. The upper face of the plate is equipped with a tube communicating with the suction port and connected to a suction group located near the tube or at a distance from it in the case of an installation with a group centralized suction. The brush-shaped elements can be retractable to facilitate the movement of the nozzle on certain types of floor, in particular carpets and rugs.
Un aspirateur a pour fonction d'aspirer des poussières. Toutefois, les fines particules qui sont mises en mouvement lors de l'opération d'aspiration, ne sont pas captées par l'aspirateur et se redéposent. En conséquence, après avoir procédé à l'aspiration d'un sol, tel qu'un carrelage ou un parquet, il convient de compléter cette opération d'aspiration par une opération de nettoyage à l'aide d'une serpillière, d'une éponge, ou d'une lingette, imbibées ou non de liquide.The function of a vacuum cleaner is to vacuum up dust. However, the fine particles which are set in motion during the suction operation are not picked up by the vacuum cleaner and are redeposited. Consequently, after having vacuumed a floor, such as a tile or parquet, it is advisable to complete this vacuuming operation by a cleaning operation using a mop, a sponge, or wipe, whether or not soaked with liquid.
Le but de l'invention est de fournir un embout pour aspirateur qui permette au cours d'une seule opération de réaliser l'aspiration et le nettoyage. A cet effet, dans l'embout qu'elle concerne, la face inférieure de la platine comporte au moins deux canaux d'aspiration entre lesquels est monté un dispositif d'essuyage, les deux canaux étant situés en avant et en arrière du dispositif d'essuyage, dans le sens de déplacement de l'embout sur le sol lors de l'opération d'aspiration. Lorsque l'embout est déplacé au sol, le canal d'aspiration situé en avant dans le sens de déplacement procède à l'aspiration des grosses particules, et le dispositif d'essuyage procède immédiatement à l'enlèvement des micro-particules, assurant ainsi le nettoyage du sol.The object of the invention is to provide a nozzle for a vacuum cleaner which makes it possible, during a single operation, to carry out suction and cleaning. To this end, in the end piece that it concerns, the underside of the plate comprises at least two suction channels between which a wiping device is mounted, the two channels being located in front and behind the device d 'wiping, in the direction of movement of the nozzle on the floor during the suction operation. When the nozzle is moved to the ground, the suction channel located forward in the direction of movement draws in large particles, and the wiping device immediately proceeds to remove the micro-particles, thereby ensuring floor cleaning.
Suivant une caractéristique de l'invention, le dispositif d'essuyage est monté de façon amovible sur la face inférieure de la platine. Il est important de pouvoir enlever le dispositif d'essuyage d'une part en vue de réaliser le nettoyage ou le remplacement de celui-ci, et d'autre part, de pouvoir utiliser l'embout sur des surfaces autres que des surfaces lisses, telles qu'un carrelage ou un parquet, après escamotage des brosses dépassant de la face inférieure de la platine. Suivant une autre caractéristique de l'invention, et afin d'assurer de bonnes fonctions d'aspiration et de nettoyage, lorsque la face inférieure de la platine est munie de brosses délimitant au moins pour partie des canaux d'aspiration, le plan inférieur du dispositif d'essuyage est situé sensiblement dans le plan inférieur des brosses.According to a characteristic of the invention, the wiping device is removably mounted on the underside of the plate. It is important to be able to remove the wiping device on the one hand in order to carry out the cleaning or replacement thereof, and on the other hand, to be able to use the nozzle on surfaces other than smooth surfaces, such as tiling or parquet, after retracting the brushes protruding from the underside of the plate. According to another characteristic of the invention, and in order to ensure good suction and cleaning functions, when the lower face of the plate is provided with brushes delimiting at least in part the suction channels, the lower plane of the wiping device is located substantially in the lower plane of the brushes.
Suivant une forme d'exécution de cet embout le dispositif d'essuyage est constitué par une lingette ou similaire. Le dispositif d'essuyage pourrait également être constitué par une éponge, une serpillière ou similaire. Suivant un mode simple de réalisation de cet embout, le dispositif d'essuyage est fixé de façon amovible sur la face inférieure de la platine par des éléments à boucles et crochets, tels que ceux connus sous la marque VELCRO.According to one embodiment of this nozzle, the wiping device consists of a wipe or the like. The wiping device could also consist of a sponge, a mop or the like. According to a simple embodiment of this end piece, the wiping device is removably attached to the underside of the plate by elements with loops and hooks, such as those known under the brand VELCRO.
Afin de favoriser le nettoyage, il est avantageux que le dispositif d'essuyage soit humide. Il est donc possible d'utiliser une lingette humide, ou d'associer au dispositif d'essuyage un dispositif d'humidification à partir d'un réservoir de liquide contenu dans l'embout, ou fixé sur la tige de manœuvre de celui-ci.In order to promote cleaning, it is advantageous for the wiping device to be wet. It is therefore possible to use a wet wipe, or to associate with the wiping device a humidification device from a reservoir of liquid contained in the nozzle, or fixed on the operating rod thereof. .
Selon une forme d'exécution de cet embout, celui-ci comporte des moyens assurant, lors du déplacement de l'embout dans un sens, la mise en communication de l'orifice d'aspiration et du canal d'aspiration situé en avant dans le sens de déplacement de l'embout et la fermeture du canal d'aspiration situé en arrière.According to one embodiment of this nozzle, the latter comprises means ensuring, during the displacement of the nozzle in one direction, the communication between the suction orifice and the suction channel located forward in the direction of movement of the nozzle and the closing of the suction channel located behind.
Cet agencement est intéressant dans la mesure où il permet de concentrer le phénomène d'aspiration en avant du dispositif d'essuyage, dans le sens de déplacement de l'embout.This arrangement is advantageous insofar as it allows the suction phenomenon to be concentrated in front of the wiping device, in the direction of movement of the nozzle.
Il est possible de disposer d'un mécanisme à bascule obturant alternativement l'un ou l'autre des canaux d'aspiration, suivant le sens de déplacement de l'embout. Suivant une autre forme d'exécution le support du dispositif d'essuyage est monté coulissant sur la platine de l'embout dans la direction de déplacement de celui-ci, afin d'obturer le canal d'aspiration situé en arrière dans le sens de déplacement de l'embout et de dégager le canal d'aspiration situé en avant. C'est donc le support du dispositif d'essuyage lui-même qui forme obturateur pour l'un ou l'autre des deux canaux d'aspiration situés en avant et en arrière dans le sens de déplacement de l'embout.It is possible to have a rocking mechanism alternately closing one or the other of the suction channels, according to the direction of movement of the nozzle. According to another embodiment, the support of the wiping device is slidably mounted on the plate of the end piece in the direction of movement of the latter, in order to close the suction channel located behind in the direction of moving the nozzle and clearing the suction channel located in front. It is therefore the support of the wiping device itself which forms a shutter for one or the other of the two suction channels located in front and back in the direction of movement of the nozzle.
Suivant une forme d'exécution de cet embout, la platine est de forme générale rectangulaire et comporte deux canaux d'aspiration disposés le long de ses deux bords longitudinaux.According to one embodiment of this end piece, the plate is of generally rectangular shape and has two suction channels arranged along its two longitudinal edges.
Suivant une autre forme d'exécution de cet embout la platine est de forme générale ovoïde et comporte deux canaux d'aspiration se rejoignant au niveau des deux sommets.According to another embodiment of this end piece the plate is generally ovoid in shape and has two suction channels meeting at the two vertices.
De toute façon l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs plusieurs formes d'exécution de cet emboutIn any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended diagrammatic drawing representing, by way of nonlimiting examples, several embodiments of this nozzle.

Figures 8 et 9 dont deux vues en perspective de dessous et en coupe transversale d'un autre embout.Figures 8 and 9 including two perspective views from below and in cross section of another tip.
La figure 1 représente un embout 2 pour aspirateur, comprenant une platine 3 de forme générale rectangulaire. Cette platine 3 comporte une face supérieure 4 au milieu de laquelle est ménagé un orifice d'aspiration 5. Un tuyau 6 est connecté sur cet orifice d'aspiration, le tuyau 6 étant, à son autre extrémité, relié à un groupe d'aspiration qui peut être soit mobile et situé à proximité du tuyau 6, soit fixe dans le cas d'une installation d'aspiration centralisée.FIG. 1 represents a nozzle 2 for a vacuum cleaner, comprising a plate 3 of generally rectangular shape. This plate 3 has an upper face 4 in the middle of which is provided a suction port 5. A pipe 6 is connected to this suction port, the pipe 6 being, at its other end, connected to a suction group which can be either mobile and located near the pipe 6, or fixed in the case of a centralized suction installation.
La face inférieure 7 de la platine 3 comporte deux séries de brosses 8 disposées à proximité des bords longitudinaux de celle-ci. Chaque série de brosses 8 délimite, du côté extérieur, un canal d'aspiration respectivement 9, 10 allongé, les deux canaux 9, 10 convergeant, dans la partie centrale de la platine vers l'orifice d'aspiration 5. La surface comprise entre les canaux d'aspiration 9 et 10 sert à la fixation de façon amovible d'un dispositif d'essuyage constitué par une lingette 1 2.The underside 7 of the plate 3 comprises two series of brushes 8 arranged near the longitudinal edges thereof. Each series of brushes 8 delimits, on the outside, a suction channel 9, 10 respectively elongated, the two channels 9, 10 converging, in the central part of the plate towards the suction orifice 5. The surface between the suction channels 9 and 10 is used for removably fixing a wiping device consisting of a wipe 1 2.
En pratique, cette lingette 1 2 peut être humide, ou humidifiée à l'aide d'un liquide véhiculé vers la lingette à partir d'un réservoir intégré dans l'embout, non représenté au dessin. Lorsque la brosse est déplacée dans le sens de la flèche représentée à la figure 3, le canal d'aspiration 9 aspire les poussières sur le sol, puis la lingette réalise le nettoyage des micro-particules. Lorsque l'embout est déplacé en sens inverse, c'est le canal d'aspiration 10 qui est situé en avant de la lingette et qui réalise l'aspiration des grosses poussières avant nettoyage par la lingette 1 2.In practice, this wipe 1 2 can be wet, or humidified using a liquid conveyed to the wipe from a reservoir integrated in the nozzle, not shown in the drawing. When the brush is moved in the direction of the arrow shown in Figure 3, the suction channel 9 sucks the dust on the floor, then the wipe cleans the micro-particles. When the nozzle is moved in the opposite direction, it is the suction channel 10 which is located in front of the wipe and which carries out the suction of large dust before cleaning with the wipe 1 2.
Les figures 4 à 6 représentent une seconde forme d'exécution de cet embout pour aspirateur dans laquelle les mêmes éléments sont désignés par les mêmes références que précédemment. Dans ce cas, la lingette 1 2 est montée sur un support 1 3, coulissant dans la direction de déplacement de l'embout. Ce coulissement est réalisé grâce à des galets 14 solidaires du support 1 3, engagés dans des rails 1 5 ménagés dans la platine. Du fait du léger accrochage produit par l'appui de la lingette 1 2 sur le sol, lorsque l'embout est déplacé dans le sens de la flèche de la figure 5, le support 1 3 de la lingette 1 2 tend à se déplacer vers la droite, et à obturer le canal 10 qui se trouve en arrière dans le sens de déplacement de l'embout, laissant ouvert le canal 9 d'aspiration et concentrant l'aspiration au niveau de ce canal 9 qui est situé en avant dans le sens de déplacement de l'embout. La figure 7 représente une troisième forme d'exécution de cet embout, qui possède une forme ovoïde, des brosses 8 étant ménagées sur toute la périphérie de l'embout, les deux canaux d'aspiration 9 et 10 se rejoignant au niveau des deux extrémités, ces extrémités étant munies d'entrées latérales 16 pour l'air aspiré. Cette figure montre un mode de fixation de la lingette 1 2 à l'aide de bandes 1 7 de matériau à boucles et crochets connues sous la marque VELCRO. Les bandes 1 7 sont réalisées par exemple avec ménagement de boucles, alors que la lingette 1 2 comporte des crochets, ou est équipée de bandes comportant des crochets. Les figures 8 et 9 représentent une autre forme d'exécution de cet embout, dans laquelle les mêmes éléments sont désignés par les mêmes références que précédemment. Dans ce cas, les deux canaux d'aspiration 9 et 10 sont reliés à l'autre par deux canaux latéraux 18, l'orifice d'aspiration 5 débouchant dans le canal 10.Figures 4 to 6 show a second embodiment of this nozzle for a vacuum cleaner in which the same elements are designated by the same references as above. In this case, the wipe 1 2 is mounted on a support 1 3, sliding in the direction of movement of the nozzle. This sliding is achieved by rollers 14 secured to the support 1 3, engaged in rails 1 5 formed in the plate. Due to the slight snag produced by the support of the wipe 1 2 on the ground, when the nozzle is moved in the direction of the arrow in Figure 5, the support 1 3 of the wipe 1 2 tends to move towards the right, and to close the channel 10 which is behind in the direction of displacement of the end piece, leaving open the suction channel 9 and concentrating the suction at this channel 9 which is located forward in the direction of movement of the nozzle. Figure 7 shows a third embodiment of this nozzle, which has an ovoid shape, brushes 8 being formed over the entire periphery of the nozzle, the two suction channels 9 and 10 meeting at the two ends , these ends being provided with lateral inlets 16 for the aspirated air. This figure shows a method of fixing the wipe 1 2 using strips 1 7 of material with loops and hooks known under the brand VELCRO. The strips 1 7 are produced for example with gentle loops, while the wipe 1 2 has hooks, or is equipped with strips having hooks. Figures 8 and 9 show another embodiment of this tip, in which the same elements are designated by same references as before. In this case, the two suction channels 9 and 10 are connected to the other by two lateral channels 18, the suction orifice 5 opening into the channel 10.
Comme il ressort de ce qui précède l'invention apporte une grande amélioration à la technique existante en fournissant un embout pour aspirateur permettant, en une seule opération de réaliser l'aspiration des poussières et le nettoyage des micro particules.As is apparent from the above, the invention brings a great improvement to the existing technique by providing a nozzle for a vacuum cleaner allowing, in a single operation to carry out the suction of dust and the cleaning of micro particles.
Comme il va de soi l'invention ne se limite pas aux seules formes d'exécution de cet embout, décrites ci-dessus à titre d'exemples, elle en embrasse au contraire toutes les variantes. C'est ainsi notamment que le dispositif d'essuyage pourrait être constitué par exemple par une éponge, que les canaux 9 et 10 pourraient être alternativement ouverts et fermés en fonction du sens de déplacement de l'embout par l'intermédiaire d'un clapet, ou encore que l'embout pourrait comporter un réservoir de liquide destiné à imbiber le dispositif d'essuyage, sans que l'on sorte pour autant du cadre de l'invention. As it goes without saying, the invention is not limited to the sole embodiments of this nozzle, described above by way of examples, on the contrary it embraces all of the variants. Thus in particular that the wiping device could be constituted for example by a sponge, that the channels 9 and 10 could be alternately open and closed according to the direction of movement of the nozzle by means of a valve. , or that the nozzle could include a liquid reservoir intended to soak the wiping device, without thereby departing from the scope of the invention.
