Description

L'invention concerne un suceur pour un aspirateur à poussières, particulièrement adapté pour les aspirateurs de faible puissance dont le bâti se trouve intégré dans un manche rigide articulé par rapport au suceur et directement manipulé par un opérateur, généralement appelés aspirateurs « balai ». Elle concerne aussi un aspirateur à poussières en tant que tel comprenant un tel suceur.The invention relates to a nozzle for a dust vacuum cleaner, particularly suitable for low-power vacuum cleaners whose frame is integrated in a rigid handle articulated relative to the nozzle and directly manipulated by an operator, generally called "sweeping" vacuum cleaners. It also relates to a vacuum cleaner as such comprising such a nozzle.

Les aspirateurs balais, par exemple décrits par les documents EP1611829 et EP0909546 , comprennent un manche rigide articulé selon plusieurs degrés de liberté par rapport au suceur posé sur le sol afin de favoriser leur manipulation. Les suceurs remplissent par nature un rôle primordial pour l'efficacité du nettoyage de l'ensemble de l'aspirateur puisqu'ils remplissent la fonction d'extraire les poussières et déchets du sol à nettoyer. Pour les aspirateurs balais qui fonctionnent à faible puissance, pour des flux entre 9 et 15 l/s, leur rôle est d'autant plus important que la puissance d'aspiration utilisée est faible.Broom vacuum cleaners, for example described by the documents EP1611829 and EP0909546 , comprise a rigid handle articulated according to several degrees of freedom with respect to the nozzle placed on the ground in order to promote their manipulation. Suckers by their very nature play a vital role in the efficiency of the cleaning of the entire vacuum cleaner as they fulfill the function of extracting dust and waste from the floor to be cleaned. For vacuum cleaners that operate at low power, for flows between 9 and 15 l / s, their role is even more important than the suction power used is low.

Pour cette raison, le document EP1611829 décrit une solution particulière dans laquelle le suceur d'un aspirateur balai présente une forme sensiblement rectangulaire, avec une paroi frontale en arc de cercle pour favoriser le déplacement du suceur, et une semelle particulièrement adaptée pour le nettoyage performant d'un sol par un aspirateur balai. Toutefois, une telle solution présente l'inconvénient de ne pas pouvoir facilement intervenir dans les recoins ou les parties difficiles d'accès.For this reason, the document EP1611829 discloses a particular solution in which the suction nozzle of a vacuum cleaner has a substantially rectangular shape, with a front wall in an arc to promote the displacement of the nozzle, and a particularly suitable sole for the efficient cleaning of a soil by a vacuum cleaner broom. However, such a solution has the disadvantage of not being able to easily intervene in corners or difficult to access parts.

Dans un autre type d'aspirateurs à plus forte puissance, tel que décrit par le document EP1488726 , il est connu d'utiliser un suceur avec une forme triangulaire, présentant des ouvertures latérales et une ouverture frontale, afin de permettre l'accès facile à des parties difficiles comme des coins et recoins, tout en favorisant la meilleure performance possible. Un telle solution n'est toutefois pas spécifiquement adaptée à un aspirateur balai et exige une forte puissance pour que les poussières soient conduites depuis les différentes ouvertures du suceur vers le conduit d'aspiration central. De plus, même si cette solution prévoit des brosses au niveau des ouvertures latérales pour mieux capter les poussières, cette solution conserve une performance qui peut être améliorée.In another type of vacuum cleaner with higher power, as described by the document EP1488726 it is known to use a nozzle with a triangular shape, having lateral openings and a front opening, to allow easy access to difficult parts such as nooks and crannies, while promoting the best possible performance. Such a solution is however not specifically adapted to a sweeper and requires a high power so that the dust is conducted from different openings of the nozzle to the central suction duct. Moreover, even if this solution provides brushes at the side openings to better capture dust, this solution retains a performance that can be improved.

Le document FR2773317 décrit un suceur pour aspirateur de forme rectangulaire. La semelle comprend un orifice d'aspiration est un canal transversal communiquant avec cette orifice. Par ailleurs, le canal débouche sur la périphérie de la semelle par des orificesThe document FR2773317 describes a suction nozzle for a rectangular shaped vacuum cleaner. The sole includes a suction port is a transverse channel communicating with this port. In addition, the channel opens on the periphery of the soleplate by orifices

Le document US 2554238 décrit un suceur pour aspirateur selon le préambule de la revendication 1.The document US 2554238 describes a suction nozzle according to the preamble of claim 1.

L'objet de l'invention est donc de proposer un suceur pour aspirateur qui permet une grande efficacité et qui est particulièrement adapté à une mise en oeuvre pour un aspirateur balai, pour atteindre une grande performance de nettoyage des sols lisses comme des sols avec moquette.The object of the invention is therefore to provide a suction nozzle which allows a high efficiency and which is particularly suitable for use in a vacuum cleaner, to achieve a great cleaning performance of smooth floors such as floors with carpet .

La présente invention est atteinte à l'aide d'un suceur pour aspirateur comprenant une semelle présentant des reliefs formant au moins deux canaux transversaux aptes à recevoir un écoulement d'aspiration, lesdits canaux étant délimités par des nervures de grattage transversales juxtaposées, lesdites nervures s'étendant sensiblement dans la direction transversale perpendiculaire au sens de déplacement du suceur et étant aptes à gratter un sol recouvert d'une moquette pour faciliter l'aspiration des déchets s'y trouvant.The present invention is achieved with the aid of a suction nozzle comprising a sole having reliefs forming at least two transverse channels adapted to receive a suction flow, said channels being delimited by juxtaposed transverse scratching ribs, said ribs extending substantially in the transverse direction perpendicular to the direction of movement of the nozzle and being able to scrape a floor covered with carpet to facilitate the suction of waste therein.

Ainsi, la présence d'une multitude de nervures de grattage du sol, orientées perpendiculairement au sens habituel de déplacement du suceur, associées à des canaux d'aspiration, permet d'améliorer l'extraction de la poussière des sols de type moquette.Thus, the presence of a multitude of soil scraping ribs, oriented perpendicular to the usual direction of displacement of the nozzle, associated with suction channels, improves the dust extraction of carpet-type floors.

Selon l'invention, le suceur comprend une partie avant de forme triangulaire, présentant une pointe orientée vers l'avant et deux arêtes s'étendant vers l'arrière, le suceur présentant également au moins un orifice latéral aménagé dans une arête de la partie triangulaire du suceur apte à l'aspiration des poussières.According to the invention, the nozzle comprises a front portion of triangular shape, having a tip oriented towards the front and two edges extending rearwardly, the nozzle also having at least one lateral orifice arranged in a ridge of the part triangular suction nozzle suitable for dust extraction.

Avantageusement le suceur comprend un canal guidant l'écoulement d'aspiration provenant de cet au moins un orifice latéral jusqu'à l'un des canaux.Advantageously, the nozzle comprises a channel guiding the suction flow coming from this at least one lateral orifice to one of the channels.

Un tel orifice latéral permet de capturer la poussière et les déchets qui viennent glisser le long de l'arête du suceur lorsque ce dernier est déplacé sur le sol, sans avoir à déplacer le suceur vers lesdits déchets.Such a side port makes it possible to capture the dust and the waste which is slid along the edge of the nozzle when the latter is moved on the ground, without having to move the nozzle to said waste.

Cette capture des déchets est améliorée par la présence de plusieurs orifices latéraux reliés à un premier canal parallèle à l'arête de la partie triangulaire du suceur, ce premier canal étant relié à au moins l'un des canaux transversaux.This capture of waste is improved by the presence of several lateral orifices connected to a first channel parallel to the edge of the triangular portion of the nozzle, this first channel being connected to at least one of the transverse channels.

Selon une mise en oeuvre préférée de l'invention, les nervures de grattage sont interrompues dans leur partie centrale par un canal longitudinal, permettant de canaliser les flux et donc les poussières.According to a preferred embodiment of the invention, the scraping ribs are interrupted in their central part by a longitudinal channel, to channel the flow and therefore the dust.

Avantageusement, le suceur comprend une ouverture dans la surface inférieure de la semelle du suceur reliée à au moins l'un des canaux délimité par au moins une nervure de grattage par au moins une ouverture prévue dans la nervure, l'ouverture de la surface inférieure de la semelle du suceur étant reliée à un conduit d'aspiration positionné dans la partie haute du suceur. Une telle ouverture permet de conduire les différents flux provenant des canaux latéraux vers l'intérieur du suceur.Advantageously, the nozzle comprises an opening in the lower surface of the sole of the nozzle connected to at least one of the channels delimited by at least one scraping rib by at least one opening provided in the rib, the opening of the lower surface. the sole of the nozzle being connected to a suction duct positioned in the upper part of the nozzle. Such an opening makes it possible to drive the different flows coming from the lateral channels towards the inside of the nozzle.

Selon cette configuration, l'ouverture de la surface inférieure de la semelle du suceur est avantageusement positionnée dans une zone arrière du suceur de forme rectangulaire, et intègre une brosse automatique, permettant d'augmenter l'efficacité de dépoussiérage des sols de type moquette.According to this configuration, the opening of the lower surface of the soleplate of the nozzle is advantageously positioned in a rear zone of the nozzle of rectangular shape, and incorporates an automatic brush, to increase the dust removal efficiency of carpet-type floors.

Par ailleurs, une amélioration d'un tel suceur consiste en un orifice frontal disposé au niveau de la pointe du suceur relié par un canal longitudinal sous la semelle du suceur vers une ouverture antérieure apte à conduire les poussières dans une zone antérieure du canal d'aspiration.Furthermore, an improvement of such a nozzle consists of a front orifice disposed at the tip of the nozzle connected by a longitudinal channel under the sole of the nozzle to an anterior opening capable of driving the dust in an anterior zone of the channel. aspiration.

Un tel suceur présente ainsi une ouverture frontale permettant d'aspirer des déchets volumineux qui sont introduits directement dans le suceur, indépendamment des canaux transversaux.Such a nozzle thus has a front opening to suck voluminous waste that is introduced directly into the nozzle, independently of the transverse channels.

Avantageusement, le suceur comprend une semelle pleine disposée derrière l'ouverture de la surface inférieure de la semelle du suceur comprenant des bandes arrache-fils.Advantageously, the nozzle comprises a solid sole disposed behind the opening of the lower surface of the sole of the nozzle comprising strips son-son.

Ainsi, le passage du suceur sur un sol à nettoyer permet, successivement, l'action de l'ouverture frontale, puis des nervures de grattage associées aux canaux latéraux d'aspiration, enfin des bandes arrache-fils de la semelle arrière, les actions successives et différentes de ces moyens de dépoussiérage permettant un dépoussiérage optimisé et rapide des surfaces de type moquette.Thus, the passage of the nozzle on a floor to be cleaned allows, successively, the action of the front opening, then the scraping ribs associated with the lateral suction channels, finally tear strips son of the rear sole, the actions successive and different of these means of dedusting allowing an optimized and fast dedusting of the surfaces of the carpet type.

Avantageusement, afin d'extraire au mieux les poussières des fibres des sols, la section d'au moins l'un des canaux d'aspiration diminue de l'avant vers l'arrière du suceur, ce qui permet d'induire une accélération des écoulements d'aspiration suivant ces canaux.Advantageously, in order to extract the dust of the soil fibers as well as possible, the section of at least one of the suction channels decreases from the front to the rear of the nozzle, which makes it possible to induce an acceleration of suction flows along these channels.

La présente invention vise également un aspirateur caractérisé en ce qu'il comprend un suceur selon l'une des caractéristiques précédentes.The present invention also relates to a vacuum cleaner characterized in that it comprises a nozzle according to one of the preceding features.

Avantageusement, l'aspirateur est un aspirateur balai, comprenant un suceur relié à un manche directement manipulable par un opérateur, ainsi qu'un moteur et un dispositif de stockage des déchets.Advantageously, the vacuum cleaner is a vacuum cleaner, comprising a nozzle connected to a handle directly manipulated by an operator, and a motor and a waste storage device.

Un tel suceur est en effet bien adapté à ce type d'aspirateur, présentant des débits plus faibles que les aspirateurs de type aspirateurs traîneaux, le suceur étant particulièrement efficace, même pour des débits peu importants, le débit étant généralement compris entre 9 et 15 l/s.Such a nozzle is in fact well adapted to this type of vacuum cleaner, having lower flow rates than suction-type suction vacuums, the nozzle being particularly effective, even for low flow rates, the flow rate being generally between 9 and 15 l / s.

La figure 1 représente un aspirateur balai 1, comprenant un suceur 2 dans sa partie inférieure relié à un manche 4 par une partie intermédiaire de liaison 3. Le manche 4 comprend une poignée 8 à son extrémité supérieure et forme un bâti qui comprend une batterie 5, un moteur 6, et un dispositif de séparation et stockage 7 des déchets, qui est amovible afin de pouvoir être nettoyé. Ce manche 4 est articulé selon plusieurs degrés de liberté par rapport au suceur 2 et directement manipulé par l'utilisateur à la manière d'un balai, afin de déplacer le suceur 2 sur le sol à nettoyer.The figure 1 represents a vacuum cleaner 1, comprising a nozzle 2 in its lower part connected to a handle 4 by an intermediate connecting portion 3. The handle 4 comprises a handle 8 at its upper end and forms a frame which comprises a battery 5, a motor 6, and a device for separating and storing waste 7, which is removable in order to be cleaned. This handle 4 is articulated according to several degrees of freedom with respect to the nozzle 2 and directly manipulated by the user in the manner of a broom, in order to move the nozzle 2 on the floor to be cleaned.

Le suceur 2 présente une forme particulière comprenant une pointe 10 destinée à être orientée vers l'avant et une arête arrière 9 transversale au bord de laquelle sont montées des roulettes 11 pour faciliter son avancée. Pour la description suivante, nous définissons la direction longitudinale x comme l'axe de symétrie horizontal du suceur passant au centre de son arête arrière 9 et par sa pointe 10, orientée de l'arrière vers l'avant. Cet axe x représente donc la direction naturelle de déplacement du suceur. Nous appelons y l'axe transversal horizontal perpendiculaire à l'axe longitudinal x. Enfin, nous appelons z la direction verticale orientée vers le haut, perpendiculaire au plan du suceur défini par les axes x et y.The nozzle 2 has a particular shape comprising a tip 10 intended to be oriented towards the front and a rear transverse edge 9 at the edge of which are mounted rollers 11 to facilitate its advance. For the following description, we define the longitudinal direction x as the horizontal axis of symmetry of the nozzle passing in the center of its rear edge 9 and its tip 10, oriented from the rear to the front. This axis x represents the natural direction of displacement of the nozzle. We call y the horizontal transverse axis perpendicular to the longitudinal axis x. Finally, we call z the vertical direction pointing upwards, perpendicular to the plane of the nozzle defined by the x and y axes.

La figure 2 permet de voir de dessus le capot 22 du suceur qui comprend une forme qui peut être décomposée en une partie avant triangulaire, s'étendant sur environ les trois quarts de la longueur du suceur, et une partie arrière de forme sensiblement rectangulaire, délimitée par deux angles avant 12, 13 et deux angles arrière 14, 15, la jonction entre ces derniers formant l'arête arrière 9. Les cinq angles 10, 12, 13, 14, 15 suffisent donc à délimiter la géométrie horizontale du suceur.The figure 2 can be seen from above the cap 22 of the nozzle which comprises a shape that can be decomposed into a triangular front portion, extending over about three quarters of the length of the nozzle, and a rear portion of substantially rectangular shape, defined by two front angles 12, 13 and two rear corners 14, 15, the junction between them forming the rear edge 9. The five corners 10, 12, 13, 14, 15 are therefore sufficient to define the horizontal geometry of the nozzle.

La partie avant triangulaire du suceur comprend donc deux arêtes qui s'étendent depuis la pointe avant 10 vers respectivement les angles avant 12, 13. Un conduit d'aspiration 16 de section sensiblement circulaire, visible sur la figure 2, s'étend sous le capot 22 du suceur, depuis une zone antérieure 17 positionnée dans une partie centrale de la partie triangulaire du suceur jusqu'à une zone arrière 18 positionnée dans la partie arrière rectangulaire du suceur. Ce conduit d'aspiration 16 s'étend le long de l'axe longitudinal médian du suceur. Il est relié dans sa zone arrière 18 à un tube flexible secondaire 19, qui permet de relier ce conduit primaire 16 sensiblement horizontal au manche 4 d'inclinaison variable, qui peut occuper une position verticale. Le tube souple secondaire 19 sert donc d'intermédiaire entre le suceur 2 et le manche 4, et comprend dans sa partie supérieure 20 une zone de liaison destinée à recevoir le manche rigide 4 de l'aspirateur balai.The triangular front portion of the nozzle therefore comprises two ridges that extend from the front tip 10 to respectively the front corners 12, 13. A suction pipe 16 of substantially circular section, visible on the figure 2 extends under the hood 22 of the nozzle, from an anterior zone 17 positioned in a central portion of the triangular portion of the nozzle to a rear zone 18 positioned in the rectangular rear portion of the nozzle. This suction duct 16 extends along the median longitudinal axis of the nozzle. It is connected in its rear zone 18 to a secondary flexible tube 19, which allows to connect this substantially horizontal primary conduit 16 to the handle 4 of variable inclination, which can occupy a vertical position. The secondary flexible tube 19 thus serves as an intermediate between the nozzle 2 and the handle 4, and comprises in its upper part 20 a connecting zone for receiving the rigid handle 4 of the vacuum cleaner brush.

L'invention porte particulièrement sur la géométrie de la semelle 21 du suceur 2, visible sur la figure 4, qui est directement destinée à attirer les poussières et déchets depuis le sol jusque dans le conduit primaire 16 du suceur avant d'atteindre le conduit du manche 4 de l'aspirateur pour finalement être retenus dans le dispositif de séparation et stockage 7.The invention relates particularly to the geometry of the sole 21 of the nozzle 2, visible on the figure 4 , which is directly intended to attract dust and waste from the ground into the primary conduit 16 of the nozzle before reaching the duct of the handle 4 of the vacuum cleaner to finally be retained in the separation and storage device 7.

La géométrie de la semelle 21 du suceur permet deux types d'aspiration selon le mode d'exécution choisi.The geometry of the sole 21 of the nozzle allows two types of suction according to the selected embodiment.

Le premier type d'aspiration repose sur un orifice frontal vertical 25 prévu dans le rebord vertical frontal de la semelle du suceur, au niveau de sa pointe 10, comme cela est particulièrement visible sur la figure 3. Cet orifice 25 présente des dimensions importantes pour permettre d'aspirer des déchets ou grosses poussières en approchant simplement la pointe 10 du suceur à leur proximité.The first type of suction is based on a vertical front orifice 25 provided in the vertical vertical flange of the sole of the nozzle, at its tip 10, as is particularly visible on the figure 3 . This orifice 25 has significant dimensions to allow to suck waste or large dust by simply approaching the tip 10 of the nozzle in their vicinity.

L'orifice 25 conduit vers un canal antérieur longitudinal 26 de faible longueur, aménagé dans la semelle du suceur, qui débouche par le haut sur la zone antérieure 17 du conduit d'aspiration 16. Ce canal antérieur 26 est un canal ouvert vers le bas, formé par une portion ajourée de la semelle du suceur. Un flux d'air le parcourt à grande vitesse en entraînant les déchets depuis le sol vers le conduit d'aspiration 16, qui est disposé dans la partie haute du suceur et qui est un conduit tubulaire, à l'exception d'ouvertures de liaison 67, 68.The orifice 25 leads to a longitudinal longitudinal channel 26 of short length, arranged in the sole of the nozzle, which opens at the top on the anterior zone 17 of the suction duct 16. This anterior channel 26 is an open channel downwards formed by a perforated portion of the sole of the nozzle. A flow of air travels at high speed driving the waste from the ground to the suction duct 16, which is arranged in the upper part of the nozzle and which is a tubular conduit, except for connecting openings 67, 68.

La jonction entre ce canal ouvert antérieur 26 et le conduit d'aspiration tubulaire 16 du suceur est réalisée par l'intermédiaire de l'ouverture avant 33 de la semelle du suceur, sensiblement verticale, particulièrement visible sur la figure 7, aménagée entre une plaque sensiblement horizontale 28 formant une surface inférieure pleine de la semelle au niveau de la partie triangulaire du suceur et la paroi supérieure du conduit 16.The junction between this anterior open channel 26 and the tubular suction duct 16 of the nozzle is made via the front opening 33 of the sole of the nozzle, substantially vertical, particularly visible on the figure 7 , arranged between a substantially horizontal plate 28 forming a solid lower surface of the sole at the triangular portion of the nozzle and the upper wall of the conduit 16.

Cette plaque 28 présente une forme triangulaire dont la pointe 29 est positionnée en face de l'orifice 25 et dont les arêtes qui s'étendent vers l'arrière sont parallèles aux arêtes de la partie triangulaire du suceur. L'ouverture verticale 33, délimitée par cette plaque, s'étend depuis la pointe 29 jusqu'à deux points 30, 31, positionnés dans la partie avant de ces arêtes.This plate 28 has a triangular shape whose tip 29 is positioned in front of the orifice 25 and whose edges which extend rearwardly are parallel to the edges of the triangular portion of the nozzle. The vertical opening 33 delimited by this plate, extends from the point 29 to two points 30, 31, positioned in the front part of these edges.

L'écartement entre ces points arrière 30, 31 délimitant l'ouverture 33 de jonction avec le conduit d'aspiration 16 permet de garantir que les déchets qui sont aspirés par l'orifice frontal 25 ne peuvent pas échapper à leur entrée dans la partie antérieure 17 du conduit d'aspiration 16. En remarque, deux petites roues 32 sont aménagées sous la plaque triangulaire 28 pour faciliter le déplacement du suceur.The spacing between these rear points 30, 31 delimiting the opening 33 joining the suction duct 16 ensures that the waste that is sucked by the front orifice 25 can not escape their entry into the front part. 17 of the suction duct 16. Note, two small wheels 32 are arranged under the triangular plate 28 to facilitate the movement of the nozzle.

Le second type d'aspiration repose sur des orifices latéraux 35 aménagés au sein des deux arêtes latérales de la partie triangulaire antérieure du suceur, particulièrement visible sur la figure 6. Selon le mode d'exécution choisi, quatre orifices latéraux 35, 35' sont prévus sur chacune de ces arêtes. Ces orifices 35, 35' conduisent tous vers un canal de surface ouvert 36 s'étendant parallèlement aux arêtes latérales du suceur depuis les angles 12, 13 de ces arêtes au niveau desquels sont positionnés les orifices latéraux 35' les plus reculés, jusqu'au canal antérieur 26 proche de la pointe 10 du suceur.The second type of aspiration rests on lateral orifices 35 arranged within the two lateral edges of the anterior triangular part of the nozzle, which is particularly visible on the figure 6 . According to the embodiment chosen, four lateral orifices 35, 35 'are provided on each of these edges. These orifices 35, 35 'all lead to an open surface channel 36 extending parallel to the lateral edges of the nozzle from the corners 12, 13 of these edges at which the latermost lateral orifices 35' are positioned, up to anterior channel 26 near the tip 10 of the nozzle.

Sur chacune de ces arêtes latérales du suceur, l'orifice 35 le plus avancé se trouve au niveau de la partie arrière de l'ouverture frontale 33, au niveau des extrémités arrière 30, 31 de cette ouverture. Enfin, deux autres orifices latéraux sont disposés autour de la zone centrale de ces arêtes, afin d'obtenir une répartition assez homogène de ces orifices latéraux, visible sur les figures 4 et 5, et permettre la plus grande chance d'aspiration des petites poussières positionnées aux abords du suceur.On each of these side edges of the nozzle, the most advanced orifice 35 is at the rear portion of the front opening 33, at the rear ends 30, 31 of this opening. Finally, two other lateral orifices are arranged around the central zone of these ridges, in order to obtain a homogeneous distribution of these lateral orifices, visible on the figures 4 and 5 , and allow the greatest chance of suction of small dust positioned near the nozzle.

A l'arrière de la plaque 28 triangulaire du suceur s'étendent quatre canaux transversaux 37 ouverts, aménagés par des reliefs dans la surface inférieure de la semelle du suceur. Ces canaux 37 sont délimités par quatre nervures 38, 38' transversales. Chaque canal transversal relie entre eux les deux canaux latéraux 36, selon une jonction arrondie favorisant le virage à angle aigu des flux d'air provenant de ces canaux latéraux 36 vers les canaux transversaux 37.At the rear of the triangular plate 28 of the nozzle extend four transverse channels 37 open, arranged by reliefs in the lower surface of the sole of the nozzle. These channels 37 are delimited by four ribs 38, 38 'transverse. Each transverse channel interconnects the two lateral channels 36, in a rounded junction favoring the acute angle turn of the air flows coming from these lateral channels 36 towards the transverse channels 37.

Les trois nervures transversales 38 les plus avancées sont interrompues dans leur partie centrale pour le passage d'un canal central longitudinal 39. La nervure 38' la plus reculée comprend cinq ouvertures 41, dont une ouverture centrale alignée avec le canal central longitudinal 39.The three most advanced transverse ribs 38 are interrupted in their central part for the passage of a longitudinal central channel 39. The most retracted rib 38 'comprises five openings 41, including a central opening aligned with the longitudinal central channel 39.

Immédiatement derrière cette dernière nervure 38' se trouve une ouverture horizontale rectangulaire 40 s'étendant au sein d'une plaque arrière 42 définissant une partie pleine sensiblement horizontale à l'arrière du suceur facilitant son déplacement. Cette plaque pleine 42 occupe sensiblement la surface arrière rectangulaire du suceur.Immediately behind this last rib 38 'is a rectangular horizontal opening 40 extending within a rear plate 42 defining a substantially horizontal solid portion at the rear of the nozzle facilitating its movement. This solid plate 42 substantially occupies the rectangular rear surface of the nozzle.

Les nervures transversales 38, 38', qui sont perpendiculaires au sens de déplacement du suceur, ont pour fonction non seulement de délimiter les canaux transversaux 37 mais aussi de pouvoir gratter un sol recouvert par exemple d'une moquette, afin de soulever les poussières et autres déchets s'y trouvant pour faciliter leur aspiration par les différents canaux ouverts disposés au sein de la semelle du suceur. Elles remplissent donc une seconde fonction technique d'arrache-fils et/ou soulève-poussière et elles ont pour cela une dimension suffisante, notamment une extension vers le bas leur permettant de s'approcher suffisamment du sol.The transverse ribs 38, 38 ', which are perpendicular to the direction of movement of the nozzle, serve not only to delimit the transverse channels 37 but also to be able to scrape a floor covered for example with a carpet, in order to lift the dust and other wastes therein to facilitate their aspiration through the various open channels disposed within the sole of the nozzle. They thus fulfill a second technical function of pull-son and / or dust-lift and they have for this a sufficient dimension, including a downward extension allowing them to get close enough to the ground.

En variante, ces nervures 38,38' pourraient présenter une autre forme, une autre orientation légèrement inclinée par rapport à l'axe transversal y, de plus ou moins 30 degrés par exemple, ou plus généralement présentant une composante transversale perpendiculaire au sens de déplacement du suceur. Le nombre de ces nervures peut également varier. Ces nervures 38, 38' pourraient se trouver à un autre emplacement que celui relativement centré du mode d'exécution illustré.As a variant, these ribs 38, 38 'could have another shape, another slightly inclined orientation with respect to the transverse axis y, more or less 30 degrees for example, or more generally having a transverse component perpendicular to the direction of displacement of the nozzle. The number of these ribs can also vary. These ribs 38, 38 'could be at a different location than the relatively centered one of the illustrated embodiment.

Cette double fonction remplie par les nervures 38, 38' de délimitation d'un canal d'écoulement 37 et de grattage du sol présente l'avantage de réduire l'encombrement sous la surface inférieure du suceur.This dual function performed by the ribs 38, 38 'delimiting a flow channel 37 and scraping the soil has the advantage of reducing the space under the lower surface of the nozzle.

Une brosse automatique 43, mise en mouvement par un moteur électrique 46, est disposée au sein de l'ouverture rectangulaire 40. Cette électrobrosse permet de soulever la poussière, les fils ou déchets sur une moquette, etc., pour mieux les aspirer. Enfin, dans la partie arrière de la plaque 42 du suceur sont disposées des zones rainurées ou bandes arrache-fils 44 destinées à favoriser le soulèvement des poussières et notamment des fibres.An automatic brush 43, set in motion by an electric motor 46, is disposed within the rectangular opening 40. This electrobrush can lift dust, son or waste on a carpet, etc., to better suck. Finally, in the rear portion of the plate 42 of the nozzle are arranged grooved areas or tear strips 44 intended to promote the lifting of dust and especially fibers.

L'ouverture horizontale 40 de la semelle du suceur débouche sur un conduit conique convergent vers le conduit d'aspiration 16 du suceur, au niveau de sa zone arrière 18. Un déflecteur 45, particulièrement visible sur la figure 7, permet d'orienter le flux entrant par cette ouverture arrière 40 de manière parallèle à l'axe du conduit d'aspiration 16 pour éviter toute collision avec le flux provenant de l'ouverture avant 33, depuis la partie antérieure 17 du conduit d'aspiration 16 généré par le premier type d'aspiration.The horizontal opening 40 of the sole of the nozzle opens on a conical duct converging towards the suction duct 16 of the nozzle, at its rear area 18. A deflector 45, particularly visible on the figure 7 , can direct the inflow through this rear opening 40 parallel to the axis of the suction duct 16 to avoid collision with the flow from the front opening 33, from the front portion 17 of the duct suction 16 generated by the first type of suction.

Cette géométrie particulière du suceur permet d'atteindre le fonctionnement avantageux qui va maintenant être décrit. Les orifices latéraux 35 de la partie triangulaire du suceur, de plus petite dimension que l'orifice frontal 25, permettent l'aspiration des poussières disposées aux alentours du suceur, non directement disposées sur le trajet de la pointe 10 du suceur. Après leur entrée par ces orifices, les poussières sont entraînées par un flux d'aspiration parcourant d'abord les canaux latéraux de surface 36 puis les canaux transversaux 37. Enfin, ces flux convergent vers l'ouverture horizontale arrière 40, par une des ouvertures 41 de la dernière nervure 38', éventuellement par le canal longitudinal central 39, pour remonter dans le conduit d'aspiration tubulaire 16 puis dans le manche 4.This particular geometry of the nozzle makes it possible to achieve the advantageous operation which will now be described. The lateral orifices 35 of the triangular portion of the nozzle, of smaller size than the front orifice 25, allow the suction of the dust disposed around the nozzle, not directly disposed in the path of the tip 10 of the nozzle. After entering through these orifices, the dust is entrained by a suction flow firstly traversing the lateral surface channels 36 and then the transverse channels 37. Finally, these flows converge towards the rear horizontal opening 40, through one of the openings 41 of the last rib 38 ', possibly by the central longitudinal channel 39, to go up in the tubular suction duct 16 and then in the handle 4.

Les différents canaux recevant les écoulements d'aspiration depuis les orifices latéraux 35 jusqu'à l'ouverture arrière 40 ont une géométrie telle que leur section de passage va en diminuant, de sorte d'induire une accélération de ces écoulements et favoriser l'entraînement de toutes les poussières et/ou déchets.The different channels receiving the suction flows from the lateral orifices 35 to the rear opening 40 have a geometry such that their passage section decreases, so as to induce an acceleration of these flows and to promote the drive all dust and / or waste.

L'invention a été illustrée dans l'hypothèse d'une géométrie particulière du suceur de l'aspirateur balai à titre non limitatif. En variante, ce suceur peut par exemple présenter une forme complètement triangulaire, voire une forme dans laquelle la partie rectangulaire est prépondérante, voire une forme sensiblement rectangulaire. De plus, les différents canaux ouverts vers le bas creusés sous la surface inférieure de la semelle pourraient présenter d'autres formes par tout type de relief, d'autres nombres, sans sortir du cadre de l'invention. Par exemple, il pourrait y avoir un seul canal transversal 37 délimité par une seule nervure transversale 38 de grattage.The invention has been illustrated in the hypothesis of a particular geometry of the nozzle of the vacuum cleaner broom without limitation. As a variant, this nozzle may, for example, have a completely triangular shape, or even a shape in which the rectangular part is predominant, or even a substantially rectangular shape. In addition, the various channels open down below the bottom surface of the sole could have other shapes by any type of relief, other numbers, without departing from the scope of the invention. For example, there could be a single transverse channel 37 delimited by a single transverse rib 38 of scraping.

De plus, l'invention a été illustrée dans le cadre d'une implémentation avec deux types d'aspiration par deux orifices différents conduisant au même conduit d'aspiration. Toutefois, elle pourrait être simplifiée dans une variante non représentée avec un seul orifice d'aspiration, l'orifice frontal étant par exemple supprimé.In addition, the invention has been illustrated in the context of an implementation with two types of suction by two different orifices leading to the same suction duct. However, it could be simplified in a variant not shown with a single suction port, the front orifice being for example removed.

De plus, même si le suceur de l'invention est particulièrement adapté à une utilisation dans un aspirateur balai, il pourrait aussi convenir à toute autre utilisation dans tout type d'aspirateur.In addition, even if the nozzle of the invention is particularly suitable for use in a vacuum cleaner, it could also be suitable for any other use in any type of vacuum cleaner.

Finalement, la solution décrite atteint ainsi les objets recherchés et présente les avantages suivants :

  • l'aspirateur reste très maniable et convivial puisque son manche conserve toute sa mobilité et que le suceur présente une forme et des orifices d'aspiration lui permettant d'atteindre des zones peu accessibles comme des recoins ;
  • la semelle du suceur est particulièrement efficace pour le soulèvement de poussières et déchets pris par exemple dans une moquette ou un tapis ;
  • la semelle du suceur présente des canaux de forme permettant la conduite performante d'un maximum de déchets vers le conduit d'aspiration par l'une des deux ouvertures.
Finally, the solution described thus achieves the desired objects and has the following advantages:
  • the vacuum remains very manageable and friendly since its handle retains all its mobility and that the nozzle has a shape and suction ports allowing it to reach inaccessible areas as nooks;
  • the sole of the nozzle is particularly effective for the lifting of dust and waste taken for example in a carpet or carpet;
  • the sole of the nozzle has shaped channels for the efficient conduct of a maximum of waste to the suction duct by one of the two openings.
