An independent claim is also included for wastes collecting electric apparatus of upright vacuum cleaner type.

Description

La présente invention concerne un suceur d'aspirateur à poussières, et plus particulièrement une amélioration de l'efficacité de collecte des déchets par un tel suceur.The present invention relates to a dust suction nozzle, and more particularly to an improvement of the waste collection efficiency by such a nozzle.

La présente invention vise les aspirateurs de faible puissance, tels ceux tenus à la main par un manche et reposant sur le sol par un suceur relié au corps de l'aspirateur. Dans la suite de la description, l'expression « aspirateur balai » désignera de tels appareils.The present invention is aimed at low power vacuum cleaners, such as those held by hand by a handle and resting on the ground by a nozzle connected to the body of the vacuum cleaner. In the remainder of the description, the term "vacuum cleaner" will designate such devices.

Les aspirateurs balais comportent fréquemment des batteries leur permettant une plus grande facilité d'utilisation, mais limitant encore davantage la puissance disponible.Broom vacuum cleaners frequently have batteries that allow them greater ease of use, but further limit the available power.

De nombreux documents décrivent des aspirateurs balais, notamment dans la structure particulière des sous-ensembles constitutifs, ou dans l'arrangement spécifique des accessoires de nettoyage.Many documents describe brush vacuums, especially in the particular structure of the constituent subassemblies, or in the specific arrangement of the cleaning accessories.

Par exemple, le document EP 1 033 101 décrit un aspirateur balai dont le manche est repliable.For example, the document EP 1 033 101 describes a broom vacuum cleaner whose handle is collapsible.

Toutefois, peu de documents sont consacrés au suceur d'aspirateur de ces appareils, témoignant par-là du peu de recherche effectuée sur l'augmentation et/ou l'optimisation de cet organe de collecte des déchets.However, few documents are devoted to the vacuum cleaner of these devices, testifying to the little research done on the increase and / or optimization of this body of waste collection.

Ainsi, le document US 5,107,567 décrit un aspirateur balai relié au secteur, le suceur de cet aspirateur comportant une ouverture centrale d'aspiration, bordée, d'un côté, par une brosse actionnée par une pédale localisée au niveau du capot du suceur. Ce dernier est équipé de petites roues. Dans une version perfectionnée de réalisation, la brosse est disposée dans le canal d'aspiration et le suceur comporte de grandes roues facilitant son déplacement.Thus, the document US 5,107,567 describes a brush vacuum connected to the sector, the nozzle of this vacuum having a central suction opening, bordered on one side by a brush operated by a pedal located at the cover of the nozzle. The latter is equipped with small wheels. In an improved embodiment, the brush is arranged in the suction channel and the nozzle has large wheels facilitating its movement.

Cependant, aucune indication ne mentionne une recherche ou une optimisation des caractéristiques du suceur afin d'augmenter l'efficacité d'aspiration du produit.However, no indication mentions a search or optimization of the characteristics of the nozzle to increase the suction efficiency of the product.

L'un des buts de la présente invention est de proposer un suceur d'aspirateur pour aspirateur balai de faible puissance, dont l'efficacité a été optimisée pour la puissance disponible, afin d'améliorer le rendement de collecte des déchets pour de tels appareils.One of the aims of the present invention is to provide a suction nozzle for vacuum cleaner low power, whose efficiency has been optimized for the available power, to improve the waste collection efficiency for such devices .

La présente invention est atteinte à l'aide d'un suceur d'aspirateur de forme sensiblement rectangulaire, comportant une semelle destinée à se déplacer sur une surface à nettoyer par l'intermédiaire de roues ou de patins, ladite semelle étant couverte par un capot, et présentant un canal d'aspiration ouvert vers la surface à nettoyer et s'étendant sur la largeur du suceur en reliant les deux bords latéraux dudit suceur, ainsi qu'un tube de raccordement au corps de l'aspirateur disposé à l'arrière du suceur, ledit tube étant relié au canal d'aspiration vers le milieu de celui-ci par un conduit, caractérisé en ce que le canal d'aspiration est délimité par une paroi avant et une paroi arrière, et en ce que la paroi avant forme un arc de cercle symétrique par rapport au milieu du canal.The present invention is achieved with the aid of a suction nozzle of substantially rectangular shape, comprising a soleplate intended to move on a surface to be cleaned by means of wheels or pads, said soleplate being covered by a hood , and having a suction channel open to the surface to be cleaned and extending over the width of the nozzle by connecting the two side edges of said nozzle, and a connecting tube to the body of the vacuum arranged at the rear of the nozzle, said tube being connected to the suction channel towards the middle thereof by a conduit, characterized in that the suction channel is delimited by a front wall and a rear wall, and in that the front wall forms a symmetrical circular arc with respect to the middle of the channel.

La forme en arc de cercle du bord avant délimitant le canal d'aspiration permet lorsque le suceur est déplacé vers l'avant sur des surfaces de type moquette, d'une part de solliciter différemment les poils de moquette par un mouvement présentant une composante latérale, et d'autre part d'éviter de présenter un bord « d'attaque » frontal qui peut rendre difficile le déplacement du suceur sur de telles surfaces.The arcuate shape of the front edge delimiting the suction channel allows when the nozzle is moved forward on carpeted surfaces, firstly to solicit the carpet pile differently by a movement having a lateral component and on the other hand to avoid having a frontal "leading" edge that can make it difficult to move the nozzle on such surfaces.

Avantageusement, la paroi arrière délimitant le canal d'aspiration présente la même configuration, en formant un arc de cercle symétrique par rapport à la paroi avant.Advantageously, the rear wall delimiting the suction channel has the same configuration, forming a circular arc symmetrical with respect to the front wall.

Le canal d'aspiration s'étendant sur la largeur du suceur, il est nécessaire d'optimiser la valeur de sa surface en contact avec le sol à nettoyer. En effet, une surface trop importante rendrait le déplacement difficile du suceur. Ainsi, le rayon de courbure présenté par la paroi avant et/ou arrière de délimitation du canal d'aspiration est supérieur à 500 mm et préférentiellement inférieur à 1000 mm.As the suction channel extends over the width of the nozzle, it is necessary to optimize the value of its surface in contact with the soil to be cleaned. In fact, a surface that is too large would make it difficult to move nozzle. Thus, the radius of curvature presented by the front wall and / or rear delimiting of the suction channel is greater than 500 mm and preferably less than 1000 mm.

Dans ces mêmes considérations, l'efficacité du suceur disposé sur un aspirateur balai, compte tenu de sa faible puissance, présente de bonnes valeurs lorsque la largeur du canal d'aspiration au niveau des bords latéraux du suceur est inférieure à 15 mm, et lorsque la largeur du canal d'aspiration en son milieu est comprise entre 20 et 25 mm.In these same considerations, the effectiveness of the nozzle placed on a vacuum cleaner, given its low power, has good values when the width of the suction channel at the side edges of the nozzle is less than 15 mm, and when the width of the suction channel in the middle is between 20 and 25 mm.

Afin de renforcer l'efficacité de collecte des déchets sur des sols de type moquette, les parois avant et arrière délimitant le canal d'aspiration sont proéminentes par rapport à la semelle. Ces parois constituent en quelque sorte des règles de raclage qui permettent lors de leur passage sur les sols cités, d'une part de gratter les poils de moquette, et d'autre part d'éjecter les poussières lorsque le poil reprend sa position, après la sollicitation des parois.In order to increase the efficiency of waste collection on carpet-type floors, the front and rear walls delimiting the suction channel are prominent with respect to the sole. These walls are in a way scraping rules that allow when they pass on the floors mentioned, on the one hand to scrape the carpet hairs, and on the other hand to eject the dust when the hair resumes its position, after the solicitation of the walls.

Un autre paramètre, peu étudié par ailleurs, est la profondeur du canal d'aspiration dans le suceur. Compte tenu des caractéristiques du produit et surtout de la faible puissance du moteur, de bonnes performances ont été obtenues en modifiant progressivement la profondeur du canal, des bords vers le centre. Les meilleurs résultats ont été obtenus lorsque le canal d'aspiration présente une profondeur croissante des bords latéraux vers le centre, cette profondeur étant inférieure à 2 mm au niveau des bords, et comprise entre 5 et 8 mm vers le centre, avant la liaison avec le conduit.Another parameter, little studied elsewhere, is the depth of the suction channel in the nozzle. Given the characteristics of the product and especially the low power of the engine, good performance was obtained by gradually changing the depth of the channel from the edges to the center. The best results have been obtained when the suction channel has an increasing depth of the lateral edges towards the center, this depth being less than 2 mm at the edges, and between 5 and 8 mm towards the center, before the connection with the conduit.

La présente invention trouve toute son application en association avec un appareil électrique récupérateur de déchets de type aspirateur balai, comportant un bâti à l'intérieur duquel est notamment logé un moteur, un dispositif de séparation des déchets, ledit appareil disposant d'un manche terminé par une poignée, ainsi qu'un suceur relié au bâti de l'aspirateur par un tube, ce dernier étant en liaison aéraulique avec le dispositif de séparation des déchets, ledit suceur présentant au moins l'une des caractéristiques précédemment mentionnées.The present invention finds its full application in combination with an electric waste recovery device type brush vacuum, comprising a frame inside which is housed in particular a motor, a waste separation device, said apparatus having a finished handle by a handle, and a nozzle connected to the frame of the vacuum cleaner by a tube, the latter being in a ventilation connection with the waste separation device, said nozzle having at least one of the characteristics mentioned above.

Avantageusement, la puissance électrique du moteur de l'appareil est inférieure à 500 W, les caractéristiques du suceur ayant été spécifiquement étudiées pour de faibles puissances.Advantageously, the electrical power of the motor of the apparatus is less than 500 W, the characteristics of the nozzle having been specifically studied for low power.

Afin de conférer une facilité accrue d'utilisation de l'appareil, son moteur est alimenté par des batteries logées dans le bâti de l'appareil, rendant ainsi autonome l'appareil sans contrainte de le relier au réseau pour son utilisation.In order to confer greater ease of use of the device, its engine is powered by batteries housed in the frame of the device, thus making the device autonomous without having to connect it to the network for its use.

La présente invention sera mieux comprise à l'aide de la description qui va suivre, en référence aux figures annexées, parmi lesquelles :

L'aspirateur 1 présenté figure 1 est de type balai, et comporte ainsi un bâti 2, prolongé vers le haut par une poignée 4. Le bâti renferme, de manière connue en soi, un moteur 6, un dispositif de séparation des déchets 10 en liaison aéraulique avec le moteur. Selon l'exemple présenté, le dispositif de séparation des déchets est un sac à poussières, mais un dispositif de séparation par inertie ou par effet cyclonique peut être envisagé dans le cadre de la présente invention. Le dispositif de séparation est logé dans un compartiment 12 amovible, afin de faciliter le nettoyage ou le remplacement du dispositif de séparation des déchets.The vacuum cleaner 1 shown in FIG. 1 is of the broom type, and thus comprises a frame 2, extended upwards by a handle 4. The frame contains, in a manner known per se, a motor 6, a waste separation device 10 Aeraulic connection with the engine. According to the example presented, the waste separation device is a dust bag, but an inertia or cyclonic separation device can be envisaged in the context of the present invention. The separation device is housed in a removable compartment 12, to facilitate the cleaning or replacement of the waste separation device.

Le moteur peut être alimenté par le secteur ou, préférentiellement, à l'aide de batteries 8 rechargeables. La puissance de l'aspirateur tel qu'illustré et disposant de batteries, est de 300 W. La mise en marche de l'aspirateur est assurée par un interrupteur 14 situé préférentiellement près de la poignée 4.The motor can be powered by the mains or, preferably, using rechargeable batteries 8. The power of the vacuum cleaner as shown and having batteries, is 300 W. The start of the vacuum cleaner is ensured by a switch 14 preferably located near the handle 4.

Le bâti 2 est relié à un suceur 20 par l'intermédiaire d'une tubulure 16 en liaison aéraulique avec le dispositif de séparation des déchets. Cette tubulure est liée au suceur par un tube coudé 18 articulé sur le suceur.The frame 2 is connected to a nozzle 20 via a pipe 16 in aeraulic connection with the waste separation device. This tubing is connected to the nozzle by an elbow tube 18 hinged to the nozzle.

Le suceur 20 est symétrique par rapport à l'axe x-x' du tube 18. Il comporte une semelle 26 bien visible figure 6, coiffée d'un capot 24, sur laquelle sont montées quatre roues 36 pour faciliter le déplacement du suceur. La semelle comporte une ouverture dirigée vers la surface à nettoyer et constituant le canal d'aspiration 28, s'étendant d'un bord latéral à l'autre du suceur, en étant délimité par deux parois avant 38 et arrière 39 formant les bords du canal. Ce canal est lié de façon aéraulique au tube coudé 18 par un conduit 29 visible figures 5 et 7, qui débouche dans le canal d'aspiration par une ouverture 30, sensiblement au milieu du canal d'aspiration.The nozzle 20 is symmetrical with respect to the x-x 'axis of the tube 18. It comprises a sole 26 clearly visible Figure 6, capped with a cover 24, on which are mounted four wheels 36 to facilitate the movement of the nozzle. The sole has an opening directed towards the surface to be cleaned and constituting the suction channel 28, extending from one side edge to the other of the nozzle, being delimited by two front walls 38 and rear 39 forming the edges of the channel. This channel is aeraulically connected to the elbow tube 18 by a pipe 29 visible in FIGS. 5 and 7, which opens into the suction channel through an opening 30, substantially in the middle of the suction channel.

Le suceur comporte également deux bandes arrache-fils 32 disposées de part et d'autre du canal d'aspiration. Par ailleurs, une brosse 34 s'étendant sensiblement sur la largeur du suceur, est agencée à proximité du bord avant du suceur. Une pédale de commande 22, située au niveau du capot du suceur, permet de remonter et de descendre la brosse par rapport à la semelle du suceur, à l'aide d'une plaque d'actionnement 23 faisant levier sur la brosse 34.The nozzle also comprises two tear strips 32 arranged on either side of the suction channel. Furthermore, a brush 34 extending substantially over the width of the nozzle, is arranged near the front edge of the nozzle. A control pedal 22, situated at the level of the nozzle of the nozzle, makes it possible to raise and lower the brush relative to the sole of the nozzle, with the aid of an actuating plate 23 levering on the brush 34.

La présente invention a trait principalement aux caractéristiques du canal d'aspiration 28, en relation avec la faible puissance présentée par le moteur.The present invention relates primarily to the characteristics of the suction channel 28, in relation to the low power presented by the engine.

L'une des caractéristiques de ce canal est son augmentation de section depuis le bord latéral du suceur jusqu'au centre du suceur et l'ouverture 30. Les figures 3 et 4 permettent en effet de constater l'augmentation respective de la largeur du canal et de sa profondeur.One of the characteristics of this channel is its increase in section from the side edge of the nozzle to the center of the nozzle and the opening 30. FIGS. 3 and 4 show the respective increase in the width of the channel. and its depth.

Ainsi, figure 3, la largeur du canal d'aspiration au niveau des bords latéraux du suceur, notée 1, est de l'ordre de 13 mm. La largeur de ce même canal, à proximité de l'ouverture 30, notée L, est de l'ordre de 22 mm.Thus, Figure 3, the width of the suction channel at the side edges of the nozzle, denoted 1, is of the order of 13 mm. The width of this same channel, near the opening 30, marked L, is of the order of 22 mm.

De plus, cette augmentation de la largeur du canal d'aspiration est continuellement progressive, par la forme en arc de cercle de la paroi avant 38 du canal, permettant notamment d'avoir de meilleurs écoulements d'air dans ledit canal.In addition, this increase in the width of the suction channel is continuously progressive, by the arcuate shape of the front wall 38 of the channel, in particular to have better air flows in said channel.

Par ailleurs, tel que bien visible figure 4, le canal d'aspiration est de plus en plus profond lorsque l'on passe de l'un des bords latéraux du suceur vers l'ouverture centrale 30, par une pente progressive donnée à la paroi 40 délimitant la profondeur du canal. Ainsi, au niveau des bords, l'ouverture est de l'ordre de 2 mm, avec une légère remontée sur les bords d'environ 1 mm, alors qu'à proximité de l'ouverture 30, la profondeur du canal d'aspiration, notée h, est de 6 mm.Moreover, as clearly visible in FIG. 4, the suction channel is more and more deep when one passes from one of the lateral edges of the nozzle to the central opening 30, by a progressive slope given to the wall. 40 delimiting the depth of the channel. Thus, at the edges, the opening is of the order of 2 mm, with a slight rise on the edges of about 1 mm, while near the opening 30, the depth of the suction channel denoted h is 6 mm.

Cette augmentation de section « tridimensionnelle » permet d'obtenir de très bons résultats de collecte des déchets, puisqu'elle permet, de façon très progressive, d'augmenter les vitesses de l'air au niveau des bords du suceur, favorisant la collecte des déchets.This increase of "three-dimensional" section makes it possible to obtain very good results of waste collection, since it allows, in a very progressive way, to increase the air speeds at the edges of the nozzle, favoring the collection of waste.

De plus, cette augmentation progressive de section permet de réduire considérablement les phénomènes de turbulence dans le canal d'aspiration. Par ailleurs, la liaison entre le canal d'aspiration et le conduit 29, par l'ouverture 30, a été étudiée pour limiter les mouvements de turbulence de l'air, essentiellement en augmentant les rayons de courbure 43 des parois formant la liaison.In addition, this gradual increase in section makes it possible to considerably reduce turbulence phenomena in the suction channel. Furthermore, the connection between the suction channel and the duct 29, through the opening 30, has been studied to limit the turbulence movements of the air, essentially by increasing the radii of curvature 43 of the walls forming the connection.

En complément, les deux parois 38, 39 sont légèrement proéminentes de la semelle et permettent de procurer un effet de raclage sur le sol avant aspiration. Cette proéminence des parois du canal d'aspiration est bien visible figure 6. Toutefois, selon l'exemple proposé, lorsque le suceur est posé sur les roues, les parois 38, 39 sont situées à une distance comprise entre 0,5 et 1 mm du sol, le raclage se produisant ainsi uniquement sur des sols de type moquette où les roues s'enfoncent légèrement dans le sol.In addition, the two walls 38, 39 are slightly prominent of the sole and provide a scraping effect on the ground before suction. This protrusion of the walls of the suction channel is clearly visible in FIG. 6. However, according to the example proposed, when the nozzle is placed on the wheels, the walls 38, 39 are situated at a distance of between 0.5 and 1 mm. from the ground, scraping thus occurring only on carpet-type floors where the wheels sink slightly into the ground.

Une autre particularité du suceur tel que présenté concerne la brosse de raclage 34 disposée à proximité du bord avant du suceur, qui présente des échancrures permettant d'alterner des zones de raclage 44 avec des ouvertures 40, 42 constituant des zones d'aspiration des gros déchets, l'ouverture centrale 42 étant plus large que les ouvertures 40. Ainsi, lorsque la brosse est sortie, le passage du suceur sur le sol permet, non seulement de solliciter le sol à nettoyer, et notamment les fibres des sols de type moquette, mais également de pouvoir aspirer de gros déchets par les ouvertures 40, 42, déchets qui seraient poussés par la brosse en l'absence desdites ouvertures.Another particularity of the nozzle as shown relates to the scraper brush 34 disposed near the front edge of the nozzle, which has notches to alternate scraping areas 44 with openings 40, 42 constituting suction areas of large waste, central opening 42 being wider than the openings 40. Thus, when the brush is out, the passage of the nozzle on the floor not only solicits the soil to be cleaned, and in particular the fibers of the carpet-like floors, but also to aspire large waste by the openings 40, 42, waste that would be pushed by the brush in the absence of said openings.

Par ailleurs, tel que présenté figures 8 et 9, lorsque la brosse 34 est sortie par rotation de la pédale de commande 22, la partie avant du suceur est soulevée, les roues avant 36 ne reposent plus sur le sol et le suceur repose alors, à l'arrière sur les roues, et à l'avant sur la brosse. Ce soulèvement du suceur évite tout coincement des gros déchets (c'est à dire ceux pénétrant dans le canal d'aspiration par les ouvertures 40, 42), facilitant ainsi leur extraction du suceur par les différents conduits.Moreover, as shown in FIGS. 8 and 9, when the brush 34 is rotated out of the control pedal 22, the front part of the nozzle is raised, the front wheels 36 no longer rest on the ground and the nozzle then rests, at the back on the wheels, and at the front on the brush. This lifting of the nozzle avoids jamming large waste (ie those entering the suction channel through the openings 40, 42), facilitating their extraction of the nozzle through the various ducts.
