Description

SUCEUR D'ASPIRATEUR VACUUM CLEANER
DOMAINE TECHNIQUE La présente invention concerne un suceur d'aspirateur comportant une semelle dont le rebord présente au moins une zone angulaire et plus particulièrement un suceur comportant une semelle destinée à se déplacer sur la surface à nettoyer ayant une face supérieure munie d'un circuit de circulation d'air et une face inférieure munie d'au moins deux patins amovibles permettant au suceur de glisser sur la surface à nettoyer. Une connexion en T, montée de façon amovible sur la face supérieure de la semelle, permet de relier via ledit circuit de circulation d'air, une pluralité d'orifices d'aspiration à un tube amovible d' évacuation des déchets aspirés .TECHNICAL FIELD The present invention relates to a vacuum cleaner nozzle having a soleplate, the rim of which has at least one angular zone, and more particularly a nozzle nozzle having a soleplate intended to move over the surface to be cleaned, having an upper face provided with a circuit for air circulation and a lower face provided with at least two removable pads allowing the nozzle to slide on the surface to be cleaned. A T-shaped connection, removably mounted on the upper face of the sole, makes it possible to connect, via said air circulation circuit, a plurality of suction orifices to a removable tube for evacuating the aspirated waste.
L'invention concerne également un aspirateur comportant un tel suceur.The invention also relates to a vacuum cleaner comprising such a nozzle.
TECHNIQUE ANTERIEUREPRIOR ART
Les suceurs pour aspirateur de l'art antérieur, présentent généralement des formes et des dimensions qui rendent leur utilisation malaisée particulièrement pour aspirer des déchets situés dans des coins ou des passages étroits ou pour aspirer des déchets qui se trouvent sur des surfaces encombrées par des meubles. Dans le premier cas, l'utilisateur est obligé de changer l'embout de l'aspirateur pour atteindre les coins ou les passages étroits, tandis que dans le deuxième cas, l'utilisateur est obligé de déplacer les meubles afin de positionner la semelle du suceur au dessus des déchets.The suction nozzles for vacuum cleaners of the prior art generally have shapes and dimensions which make their use difficult, particularly for vacuuming waste located in narrow corners or passages or for vacuuming waste which is on surfaces congested with furniture. . In the first case, the user is forced to change the nozzle of the vacuum cleaner to reach corners or narrow passages, while in the second case, the user is forced to move the furniture in order to position the sole of the squeegee above the waste.
La demande internationale de brevet numéro WO84/03429 décrit un suceur pour aspirateur de forme triangulaire muni d'orifices d'aspiration latéraux situés en dessous d'une cavité d'aspiration et au milieu des côtés du triangle. Un tel suceur ne permet pas de résoudre le problème mentionné ci-dessus dans la mesure où, pour aspirer les déchets situés dans un coin ou un passage étroit, l'utilisateur doit d'abord positionner le suceur au dessus de ces déchets. Ceci n'est possible que si l'angle du coin est suffisamment large pour permettre de positionner la semelle du suceur sur les déchets. Dans le cas où cet angle est étroit, l'utilisateur est encore obligé de changer l'embout de l'aspirateur pour atteindre les déchets .International patent application number WO84 / 03429 describes a triangular suction nozzle for vacuum cleaner provided with lateral suction ports located below a suction cavity and in the middle of the sides of the triangle. Such a nozzle does not resolve the problem mentioned above insofar as, to vacuum the waste located in a corner or a narrow passage, the user must first position the nozzle above this waste. This is only possible if the corner angle is wide enough to allow the nozzle to be positioned on the waste. In the case where this angle is narrow, the user is still obliged to change the nozzle of the vacuum cleaner to reach the waste.
EXPOSE DE L'INVENTIONSTATEMENT OF THE INVENTION
Le but de l'invention est de pallier aux inconvénients mentionnés ci-dessus au moyen d'un suceur d'aspirateur comportant une semelle dont le rebord présente au moins une zone angulaire reliant deux bords adjacents quelconques du suceur, caractérisé en ce que ladite zone angulaire comporte au moins un orifice destiné à assurer une aspiration dans une direction sensiblement parallèle à la surface à nettoyer.The object of the invention is to overcome the drawbacks mentioned above by means of a vacuum cleaner nozzle having a soleplate the rim of which has at least one angular zone connecting any two adjacent edges of the nozzle, characterized in that said zone angular comprises at least one orifice intended to ensure suction in a direction substantially parallel to the surface to be cleaned.
Un tel suceur permet d'approcher une ouverture d'aspiration le plus possible des déchets situés dans des coins ou des passages étroits.Such a nozzle allows to approach a suction opening as much as possible of the waste located in corners or narrow passages.
Grâce à cet orifice, le suceur est capable d'aspirer à distance les déchets situés dans les coins ou les passages étroits même si la semelle dudit suceur n'est pas positionnée au dessus de ces déchets.Thanks to this orifice, the nozzle is capable of vacuuming the waste located in corners or narrow passages even if the sole of said nozzle is not positioned above this waste.

MEILLEURE MANIERE DE REALISER L'INVENTIONBEST WAY TO IMPLEMENT THE INVENTION
Comme on peut le voir sur la figure 2, le suceur d'aspirateur 2 comporte une semelle 4 destinée à se déplacer parallèlement à la surface à nettoyer, le rebord de ladite semelle présente une zone angulaire 6 reliant deux côtés du suceur et dont l'extrémité est arrondie afin d'éviter de détériorer les murs et les meubles pendant le nettoyage. Cette zone angulaire est avantageusement mise en valeur dans un suceur triangulaire tel que décrit dans la présente demande, à titre d'exemple de réalisation, mais l'invention peut également être appliquée à un suceur de forme quelconque, circulaire en présentant une pointe qui forme ladite zone angulaire, mais aussi pour un suceur rectangulaire possédant alors quatre zones angulaires de liaison des bords, situés aux quatre coins du suceur.As can be seen in FIG. 2, the vacuum cleaner nozzle 2 comprises a sole 4 intended to move parallel to the surface to be cleaned, the edge of said sole has an angular zone 6 connecting two sides of the nozzle and the end is rounded to avoid damaging walls and furniture during cleaning. This angular zone is advantageously highlighted in a triangular nozzle as described in the present application, by way of example of embodiment, but the invention can also be applied to a nozzle of any shape, circular with a point which forms said angular zone, but also for a rectangular nozzle then having four angular zones for connecting the edges, located at the four corners of the nozzle.
Selon une caractéristique importante de l'invention, ladite zone angulaire comporte un orifice frontal 7 destiné à assurer une aspiration dans une direction sensiblement parallèle à la surface à nettoyer. Par orifice frontal, il faut entendre une ouverture partant de la semelle, où est situé le canal d'aspiration et s ' étendant sur le bord du suceur. L'ouverture est ainsi sensiblement perpendiculaire à la surface à nettoyer.According to an important characteristic of the invention, said angular zone comprises a front orifice 7 intended to ensure suction in a direction substantially parallel to the surface to be cleaned. By frontal opening, it is meant an opening starting from the sole, where the suction channel is located and extending on the edge of the squeegee. The opening is thus substantially perpendicular to the surface to be cleaned.
Cette ouverture est de taille suffisante pour pouvoir aspirer de petits objets. Ainsi la taille de l'ouverture est supérieure à 0,5 cm2.This opening is large enough to be able to vacuum small objects. Thus the size of the opening is greater than 0.5 cm 2 .
Avantageusement, afin de ne pas créer une perte d'aspiration au niveau du sol, l'ouverture est profilée en présentant un angle de fuite à la base de telle sorte que la largeur de l'ouverture à sa base soit au moins deux fois plus importante que sa largeur à mi-hauteur.Advantageously, in order not to create a loss of suction at ground level, the opening is profiled by presenting a leak angle at the base so that the width of the opening at its base is at least twice as much important than its width at half height.
La figure 8 montre une telle ouverture 72 présentant un angle de fuite 74. La largeur 11 à sa base est au moins deux fois plus importante que sa largeur t2 à mi-hauteur.FIG. 8 shows such an opening 72 having a leak angle 74. The width 11 at its base is at least twice as large as its width t2 at mid-height.
Comme on peut le voir sur les figures 3, 5 et 6, la face supérieure de ladite semelle 4, est munie d'un circuit de circulation d'air 8 tandis que sa face inférieure comporte trois patins de glissement amovibles 9 permettant le déplacement du suceur sur la surface à nettoyer. Une connexion en T 10, montée de façon amovible sur la face supérieure de la semelle 4, permet de relier, via ledit circuit de circulation d'air 8, une pluralité d'orifices d'aspiration 7,11,14 à un tube amovible 16 d'évacuation des déchets aspirés.As can be seen in Figures 3, 5 and 6, the upper face of said sole 4 is provided with an air circulation circuit 8 while its lower face comprises three removable sliding pads 9 allowing the movement of the nozzle on the surface to be cleaned. A T-connection 10, removably mounted on the upper face of the sole 4, makes it possible to connect, via said air circulation circuit 8, a plurality of suction orifices 7, 11, 14 to a removable tube 16 for evacuating the aspirated waste.
Selon un mode préféré de réalisation de l'invention, la semelle 4 présente une forme sensiblement triangulaire dont les deux côtés adjacents 18 comportent chacun un canal latéral 19 ouvert vers la surface à nettoyer agencé le long du rebord de la semelle 4. Selon une variante de réalisation, conforme à l'exemple proposé à titre d'illustration de l'invention, chacun des canaux latéraux 19 est relié à un canal postérieur 20 agencé le long du troisième côté 21 formant la face postérieure de la semelle 4, au moyen d'un coude 22 ouvert vers la surface à nettoyer sensiblement perpendiculaire audit côté 21 et comportant au moins un orifice latéral d'aspiration 11.According to a preferred embodiment of the invention, the sole 4 has a substantially triangular shape, the two adjacent sides 18 each of which have a lateral channel 19 open to the surface to be cleaned arranged along the edge of the sole 4. According to an alternative embodiment, in accordance with the example proposed by way of illustration of the invention, each of the lateral channels 19 is connected to a rear channel 20 arranged along the third side 21 forming the rear face of the sole 4, by means of an elbow 22 open towards the surface to be cleaned substantially perpendicular to said side 21 and comprising at least one lateral suction orifice 11.
En outre, comme on peut le voir sur la figure 4, les canaux latéraux 19 communiquent avec un orifice inférieur 14 tandis que le canal postérieur 20 communique avec deux orifices inférieurs 14 situés symétriquement par rapport au milieu dudit côté postérieur 21. Ces orifices inférieurs 14 sont destinés à assurer une aspiration des déchets dans une direction perpendiculaire à la surface à nettoyer.Furthermore, as can be seen in FIG. 4, the lateral channels 19 communicate with a lower orifice 14 while the posterior channel 20 communicates with two lower orifices 14 situated symmetrically with respect to the middle of said rear side 21. These lower orifices 14 are intended to ensure suction of the waste in a direction perpendicular to the surface to be cleaned.
Comme on peut le voir sur les figures 3, 5 et 6, le circuit de circulation d'air 8 présente une forme en H ayant une gorge centrale 32 dans laquelle est monté le conduit 34 constituant la barre horizontale de la connexion en T 10 et deux gorges latérales 38 reliant chacun des deux orifices inférieurs 14 situés sur le canal postérieur 20 à l'un des deux orifices inférieurs 14 situés sur l'un des canaux latéraux 19 et au conduit 34. Les gorges latéralesAs can be seen in FIGS. 3, 5 and 6, the air circulation circuit 8 has an H shape having a central groove 32 in which is mounted the duct 34 constituting the horizontal bar of the T connection 10 and two lateral grooves 38 connecting each of the two lower orifices 14 located on the posterior channel 20 to one of the two lower orifices 14 located on one of the lateral channels 19 and to the conduit 34. The lateral grooves
38 du circuit de circulation d'air 8 sont couvertes à leurs extrémités par un premier couvercle 40 de forme plate et à leur milieu par un deuxième couvercle de forme se i- cylindrique 42 prolongeant le conduit 34 de la connexion en38 of the air circulation circuit 8 are covered at their ends by a first cover 40 of flat shape and in their middle by a second cover of i-cylindrical shape 42 extending the conduit 34 of the connection in
T 10.T 10.
Comme on peut le voir sur la figure 6, chacune des gorges latérales 38 du circuit en H comporte un déflecteur latéral 50 situé à proximité de la zone de rencontre des flux d'air entrant par les orifices inférieurs d'aspiration 14 situés l'un en face de l'autre. La connexion 10 comporte également, comme on peut le voir sur les figures 4 et 6, deux déflecteurs centraux 52 destinés à éviter une collision frontale entre les flux d' air circulant dans le conduit 34.As can be seen in FIG. 6, each of the lateral grooves 38 of the H-shaped circuit includes a lateral deflector 50 located near the area where the incoming air flows meet through the lower suction orifices 14 located one opposite each other. The connection 10 also includes, as can be seen in FIGS. 4 and 6, two central deflectors 52 intended to avoid a frontal collision between the air flows circulating in the duct 34.
Afin d' éviter les chocs entre le suceur et l'environnement lors de l'utilisation de l'aspirateur, la semelle 4, comme cela est illustré aux figures 2 et 4, est couverte sur sa face supérieure par un capot 54 en matériau souple couvrant également les bords extérieurs des côtés 18 et 21 ainsi que les coudes 22 de ladite semelle 4. Ledit capot souple 54 comporte en son milieu un trou permettant le passage de la connexion 10 pour assurer la fixation du tube 16. Notons que le capot 54 a essentiellement une fonction d' anti-choc dans la mesure où le circuit de circulation d'air 8 est totalement couvert par les couvercles 40, 42 et de ce fait le suceur peut aspirer les déchets même lorsque ce capot 54 est retiré de la face supérieure de la semelle.In order to avoid impacts between the squeegee and the environment when using the vacuum cleaner, the soleplate 4, as illustrated in FIGS. 2 and 4, is covered on its upper face by a cover 54 made of flexible material also covering the outer edges of the sides 18 and 21 as well as the elbows 22 of said sole 4. Said flexible cover 54 has in its middle a hole allowing the passage of the connection 10 to secure the tube 16. Note that the cover 54 essentially has an anti-shock function insofar as the air circulation circuit 8 is completely covered by the covers 40, 42 and therefore the squeegee can suck up the waste even when this cover 54 is removed from the face upper of the sole.
Afin d' assurer un déplacement du suceur sur des surfaces de différents types, les patins amovibles 9, représentés schématiquement aux figures 4 et 7, comportent une surface inférieure 60, ayant un bord d'attaque profilé 62, et sont munis d'une pastille centrale 64 assurant le contact avec la surface à traiter lors du déplacement de l'appareil. Ladite pastille centrale 64 peut être en PTFE (polytétrafluoréthylène) ou en tout autre matériau ayant une bonne résistance à l'abrasion et un faible coefficient de frottement. La face supérieure 66 desdits patins 9 est munie d'une couronne centrale 68 entourée par un joint annulaire 70 destiné à absorber les vibrations lorsque le suceur se déplace sur une surface accidentée.In order to ensure displacement of the nozzle on surfaces of different types, the removable pads 9, shown diagrammatically in FIGS. 4 and 7, have a lower surface 60, having a profiled leading edge 62, and are provided with a pad. central unit 64 ensuring contact with the surface to be treated when the device is moving. Said central pad 64 can be made of PTFE (polytetrafluoroethylene) or any other material having good abrasion resistance and a low coefficient of friction. The upper face 66 of said pads 9 is provided with a central ring 68 surrounded by an annular seal 70 intended to absorb vibrations when the nozzle moves on an uneven surface.
Avantageusement, les patins de glissement sont agencés à la semelle de telle sorte à surélever le suceur de la surface à nettoyer. La distance séparant le suceur du sol, que l'on peut assimiler à une garde au sol, par analogie avec le domaine automobile, permet d'établir une synergie entre une aspiration grossière par la ou les ouvertures 7, 11 et une aspiration fine par les côtés du suceur .Advantageously, the sliding pads are arranged in the sole so as to raise the nozzle from the surface to be cleaned. The distance separating the squeegee from the ground, which can be compared to ground clearance, by analogy with the automotive field, makes it possible to establish a synergy between coarse suction through the opening (s) 7, 11 and fine suction through the sides of the squeegee.
Ceci permet également d'établir un bon compromis entre la facilité pour déplacer le suceur au sol, grâce à la fuite d'air créée, et la dépression d'aspiration.This also makes it possible to establish a good compromise between the ease of moving the nozzle on the ground, thanks to the air leakage created, and the suction depression.
POSSIBILITE D'APPLICATION INDUSTRIELLE L'invention trouve son application dans le domaine des aspirateurs ménagers. POSSIBILITY OF INDUSTRIAL APPLICATION The invention finds its application in the field of household vacuum cleaners.
