Description

DISPOSITIF D'ASPIRATEUR CONÇU APTE A L'ASPIRATION D'AIR ET DE LIQUIDE SUR UNE SURFACE PLANE, ET LAME DE RACLAGE POUR UN TEL DISPOSITIF. La présente invention a pour objet un dispositif d'aspirateur, conçu apte à l'aspiration d'air et de liquide sur une surface plane, et plus particulièrement partie active dudit dispositif d'aspirateur, destinée à être déplacée sur ladite surface . VACUUM DEVICE DESIGNED FOR AIR AND LIQUID EXTRACTION ON A FLAT SURFACE, AND SCRAPING BLADE FOR SUCH A DEVICE The present invention relates to a vacuum cleaner device, designed for suction of air and liquid on a flat surface, and more particularly active part of said vacuum device, intended to be moved on said surface.
La présente invention concerne plus particulièrement le domaine des raclettes de nettoyage de surfaces planes telles que des surfaces vitrées, utilisant l'aspiration pour éliminer l'eau résiduelles de nettoyage.  The present invention more particularly relates to the field of flat surface cleaning squeegees such as glazed surfaces, using suction to remove residual cleaning water.
La présente invention n'est toutefois pas limitée à cet usage et peut très bien être appliquée au nettoyage d' autres surfaces que des surfaces vitrées .  The present invention is however not limited to this use and can very well be applied to the cleaning of other surfaces than glass surfaces.
D'autre part, la partie active du dispositif d'aspirateur selon l'invention, peut être associée sur ledit dispositif à des moyens annexes de traitement de la surface à nettoyer, que ce soit des moyens de nettoyage comme une lingette par exemple, et/ou de moyens de projection de liquide de nettoyage ou de vapeur .  On the other hand, the active part of the vacuum cleaner device according to the invention can be associated on said device with additional means for treating the surface to be cleaned, whether it be cleaning means such as a wipe, for example, and / or means for spraying cleaning liquid or steam.
Ces raclettes comportent généralement une lame de raclage souple, associée à un moyen d'aspiration actif au niveau du bord inférieur de ladite lame. On connaît déjà de tels appareils de nettoyage, et notamment ceux décrits dans le WO2010018312 par exemple, ou le document WO2009086891.  These squeegees generally comprise a flexible scraping blade, associated with an active suction means at the lower edge of said blade. Such cleaning devices are already known, and in particular those described in WO2010018312 for example, or the document WO2009086891.
L'aspiration peut être réalisée de différentes manières comme par exemple entre deux lames formant une embouchure d'aspiration, ou bien au travers d'une lingette textile disposée sous une lame de raclage et dans laquelle est recueillie l'eau résiduelle .  The suction can be carried out in different ways, for example between two blades forming a suction mouth, or through a textile cloth disposed under a scraper blade and in which is collected the residual water.
L'opération de raclage consiste à déplacer la raclette sur la surface plane dans une succession de mouvements plus ou moins rectilignes, de préférence du haut vers le bas lorsque ladite surface est verticale. Quel que soit l'appareil considéré, l'utilisateur est toujours confronté au même problème la subsistance d'une marque d'eau résiduelle à l'extrémité de la trajectoire de la raclette. Ceci est essentiellement dû au fait que l'angle que forme la lame de raclage avec la surface plane n'est pas constant mais qu'il augmente, et que de ce fait l'embouchure par laquelle l'aspiration est réalisée n'est pas de forme optimale. The scraping operation is to move the squeegee on the flat surface in a succession of more or less rectilinear movements, preferably from top to bottom when said surface is vertical. Whatever the device considered, the user is still faced with the same problem the subsistence of a mark of residual water at the end of the path of the squeegee. This is mainly due to the fact that the angle formed by the scraping blade with the flat surface is not constant but increases, and that therefore the mouth through which the suction is carried out is not of optimal shape.
Ainsi, comme cela est visible sur la figure 1 annexée, dans le cas d'une embouchure A faite de deux lames B et C formant entre elles un angle pour se rejoindre sur une ligne de contact avec la surface S à traiter, la déformation des lames B et C lors de leur application contre ladite surface S provoque le retrait de la lame B en regard de la surface S, par rapport à l'autre lame C, et cet écart va générer en bout de trajectoire un léger filet d'eau F qui ne sera pas aspiré. Plus la pression sera importante, plus la déformation le sera et plus le filet d' eau le sera également .  Thus, as can be seen in the appended FIG. 1, in the case of a mouthpiece A made of two blades B and C forming between them an angle to meet on a line of contact with the surface S to be treated, the deformation of the blades B and C during their application against said surface S causes the removal of the blade B opposite the surface S, relative to the other blade C, and this gap will generate at the end of the trajectory a light trickle of water F that will not be sucked. The higher the pressure, the more the deformation will be and the more the water will be.
D'autre part, lors de l'application contre la surface à traiter, les deux lames B et C se déforment et se rapprochent ce qui restreint les capacités d'aspiration, et ce qui nécessite de créer sur le bord de la lame qui entre en contact en premier avec le liquide résiduel, des crans, non représentés, autorisant le passage dudit liquide.  On the other hand, when applying against the surface to be treated, the two blades B and C deform and get closer which restricts the suction capabilities, and which requires creating on the edge of the blade that enters in contact first with the residual liquid, notches, not shown, allowing the passage of said liquid.
Par ailleurs, dans le cas de deux lames, on observe une perte d'aspiration aux extrémités de l'espace qui sépare les deux lames .  Moreover, in the case of two blades, there is a loss of suction at the ends of the space between the two blades.
De même, dans le cas d'une lingette de recueil de liquide résiduel, lorsqu'en fin de trajectoire on décolle l'appareil de la paroi plane, la lingette laisse une trace même minime, et malgré la réalisation d'une aspiration au travers de celle-ci.  Similarly, in the case of a residual liquid collection wipe, when at the end of the trajectory the device is taken off the flat wall, the wipe leaves a trace even minimal, and despite the achievement of a suction through of it.
On connaît également des raclettes qui comportent une seule lame percés de canaux qui débouchent en arrière de l'arête de raclage, et qui sont destinés à l'évacuation de l'eau sous l'effet d'une dépression. Une telle raclette est décrite dans le document EP 0 422 977, où les canaux sont prolongés par des tuyaux. L'inconvénient de ce type de raclette, outre le fait que les canaux peuvent aisément s'encrasser, est que par effet de capillarité, l'eau a tendance à s'agripper aux parois des canaux, en sorte de nécessiter une forte dépression, et donc une motorisation plus importante avec toutes les conséquences liées à cela, à savoir plus forte consommation, poids plus important etc ... Scrapers are also known which comprise a single blade pierced with channels which open out behind the scraping edge, and which are intended for the evacuation of water under the effect of a depression. Such a scraper is described in EP 0 422 977, where the channels are extended by pipes. The disadvantage of this type of squeegee, besides the fact that the channels can easily become clogged, is that by capillary effect, the water tends to cling to the walls of the channels, so as to require a strong depression, and therefore a greater motorization with all the consequences related to that , ie higher consumption, higher weight etc ...
La présente invention a pour but de remédier aux divers inconvénients précités, en proposant un dispositif d'aspirateur permettant de nettoyer une surface plane en laissant le moins de traces possible, quel que soit le sens dans lequel le mouvement est donné .  The present invention aims to overcome the aforementioned various drawbacks, by providing a vacuum cleaner device for cleaning a flat surface leaving as few traces as possible, regardless of the direction in which the movement is given.

- la figure 12 représente une vue schématique partielle en coupe de la même partie dans un autre mode de réalisation particulier . La présente invention concerne un dispositif d'aspirateur, non représenté, conçu apte à l'aspiration d'air et de liquide sur une surface plane, dont on peut voir sur les figures 2, 3 et 4, la partie active 1 destinée à être déplacée sur ladite surface. - Figure 12 shows a partial schematic sectional view of the same part in another particular embodiment. The present invention relates to a vacuum cleaner device, not shown, designed adapted to suction air and liquid on a flat surface, which can be seen in Figures 2, 3 and 4, the active part 1 to be moved on said surface.
Cette partie active 1 consiste en une lame de raclage de conception particulière, réalisée dans un matériau souple ou semi rigide .  This active part 1 consists of a scraping blade of particular design, made of a flexible or semi-rigid material.
Dans le mode de réalisation représenté, la lame 1 présente une section transversale en forme globale de coin, ou de sifflet, qui comporte deux pans, et notamment un pan 2 faisant face à la partie de la surface plane à racler, et un pan 3 de l'autre côté.  In the embodiment shown, the blade 1 has a cross section in the overall shape of a wedge, or whistle, which comprises two faces, and in particular a face 2 facing the part of the flat surface to be scraped, and a section 3 on the other side.
Son extrémité libre 4, destinée à être déplacée au contact de la surface plane à traiter, présente une bande plate 40, vers laquelle convergent les pans 2 et 3, et qui est sensiblement perpendiculaire au plan général de la lame 1. Alors que le pan 3 est plan, le pan 2 présente un profil particulier, à savoir que la jonction de la bande plate 40 avec le pan 2 est réalisée au travers d'un redan 20 dont le plan fait un angle, de préférence fermé, avec le plan de la bande 40 pour former une arête 21, ce redan 20 étant prolongé par une paroi oblique 22 dans laquelle sont pratiqués des trous 23, visibles sur les figures 2 et 3.  Its free end 4, intended to be moved in contact with the flat surface to be treated, has a flat strip 40, to which converge the sides 2 and 3, and which is substantially perpendicular to the general plane of the blade 1. While the pan 3 is plane, the pan 2 has a particular profile, namely that the junction of the flat strip 40 with the pan 2 is formed through a recess 20 whose plane is at an angle, preferably closed, with the plane of the strip 40 to form an edge 21, this redan 20 being extended by an oblique wall 22 in which are formed holes 23, visible in Figures 2 and 3.
La bande 40 résulte de l'épaisseur de la lame 1 à son extrémité libre 4 , qui donne à cette dernière la tenue nécessaire à la réalisation raclage par le redan 20.  The band 40 results from the thickness of the blade 1 at its free end 4, which gives the latter the holding necessary for scraping by the redan 20.
Les trous 23 sont alignés le long et en arrière de l'arête 21, et débouchent dans une cavité 10 interne à la lame 1 visible sur la figure 3, cette cavité 10 étant en liaison avec des moyens de création d'une dépression, non représentés. Ces trous 23 sont destinés à l'aspiration de l'eau résiduelle raclée par le redan 20, et plus particulièrement son arête 21.  The holes 23 are aligned along and behind the edge 21, and open into a cavity 10 internal to the blade 1 visible in Figure 3, the cavity 10 being connected with means for creating a depression, no represented. These holes 23 are intended for the suction of the residual water scraped by the redan 20, and more particularly its edge 21.
La paroi 22 est inclinée par rapport au plan général de la lame 1, cette inclinaison est destinée à permettre que les trous 23 soient orientés en sorte de d'obtenir une aspiration optimale, aussi l'angle d'inclinaison pourra être choisi en fonction de plusieurs paramètres, comme par exemple la flexibilité de la lame 1, permise par les caractéristiques de la matière utilisée. The wall 22 is inclined relative to the general plane of the blade 1, this inclination is intended to allow the holes 23 to be oriented so as to obtain a suction optimal, also the angle of inclination can be chosen according to several parameters, such as the flexibility of the blade 1, permitted by the characteristics of the material used.
La cavité 10 forme, immédiatement en arrière des trous The cavity 10 forms, immediately behind the holes
23, un élargissement qui libère le passage et évite de ralentir le débit d'air suite à l'effet de capillarité de l'eau sur les parois . 23, an enlargement that frees the passage and avoids slowing the air flow due to the effect of capillary water on the walls.
On notera que la cavité 10 comporte des renforts 11 s' étendant entre les parois 24 et 30 qui forment les deux pans, respectivement 2 et 3, en sorte d'éviter, lors d'une opération de raclage l'écrasement de la cavité 10.  It will be noted that the cavity 10 comprises reinforcements 11 extending between the walls 24 and 30 which form the two panels, respectively 2 and 3, so as to avoid, during a scraping operation, the crushing of the cavity 10 .
Comme on peut le voir plus précisément sur la figure 2, les trous 23 présentent du côté extérieur un chanfrein 25, ce qui permet d'éliminer les angles susceptibles de retenir l'eau par effet de capillarité.  As can be seen more specifically in FIG. 2, the holes 23 have a chamfer 25 on the outside, which makes it possible to eliminate the angles that can retain the water by capillary action.
En utilisation, le redan 20 racle l'eau résiduelle qui est aspirée par les trous 23. L'aspiration demeure optimale, quel que soit l'état de déformation de la lame 1.  In use, the redan 20 scrapes the residual water that is sucked through the holes 23. The suction remains optimal, regardless of the state of deformation of the blade 1.
On notera que la forme du redan 20 peut présenter des profils différents, que ce soit au niveau de son angle, ou bien de sa découpe en sorte que son arête de raclage soit prolongée d'une extension 26 dont l'extrémité est de section arrondie comme cela est visible sur la figure 5a, ou qui peut comporter plusieurs extensions 27 parallèles ou sensiblement parallèles dont les extrémités constituent autant d'arêtes, comme cela est visible sur la figure 5b, en sorte de créer plusieurs niveaux successifs de raclage, le choix de ces variantes pouvant être fonction de l'application à laquelle est destinée la lame 1.  Note that the shape of the redan 20 may have different profiles, either at its angle, or its cutting so that its scraping edge is extended by an extension 26 whose end is of rounded section as can be seen in FIG. 5a, or which may comprise several parallel or substantially parallel extensions 27 whose ends constitute as many edges, as can be seen in FIG. 5b, so as to create several successive levels of scraping, the choice these variants may be a function of the application for which the blade 1 is intended.
En référence maintenant à la figure 6 on peut voir que, de manière schématique, lors de l'utilisation de la raclette, même si le chanfrein 25 des trous 23 permet de limiter l'effet capillarité, de l'eau E peut stagner sur la paroi 24, entre deux trous 23 successifs, et il peut en résulter la subsistance de traces d'eau sur la surface nettoyée. Aussi, pour pallier cet inconvénient, il est proposé un mode préférentiel de réalisation, représenté sur les figures 7 et 8. Referring now to Figure 6 it can be seen that, schematically, when using the squeegee, even if the chamfer 25 holes 23 can limit the capillary effect, water E can stagnate on the wall 24, between two successive holes 23, and it may result in the maintenance of traces of water on the cleaned surface. Also, to overcome this drawback, it is proposed a preferred embodiment, shown in Figures 7 and 8.
Sur ces figures, on peut voir que les trous 23 sont séparés deux à deux par une bande de matière 29, qui fait partie de la paroi 24, et qui présente au niveau de sa jonction avec la paroi 30, une forme de pointe dirigée vers l'arête 21, et le chanfrein 25 des orifices des trous 23 se prolonge sur la bande de matière 29.  In these figures, it can be seen that the holes 23 are separated two by two by a strip of material 29, which is part of the wall 24, and which has at its junction with the wall 30, a pointed form directed towards the edge 21, and the chamfer 25 of the orifices of the holes 23 is extended on the strip of material 29.
En référence à la figure 9, on peut voir qu'il ne subsiste aucune aspérité susceptible retenir l'eau.  Referring to Figure 9, it can be seen that there is no roughness likely to retain water.
Ce mode de réalisation permet un nettoyage quasiment parfait. En outre, du fait du résultat obtenu, il est possible de réduire la puissance d'aspiration nécessaire, ce qui permet de réduire le poids l'appareil, ce qui rend son utilisation encore plus aisée lorsqu'il s'agit d'un appareil à main tel qu'une raclette par exemple.  This embodiment allows almost perfect cleaning. In addition, because of the result obtained, it is possible to reduce the suction power required, which reduces the weight of the device, which makes its use even easier when it is a device such as a raclette for example.
Du point de vue fabrication de ce mode de réalisation, les parois 24 et 30 peuvent venir de moulage en une seule pièce, mais préférablement , elles constituent deux lames assemblées par collage ou soudage.  From the manufacturing point of view of this embodiment, the walls 24 and 30 may be molded in one piece, but preferably they constitute two blades assembled by gluing or welding.
Selon un mode réalisation particulier, les renforts 11 sont rapportés dans la lame 1, c'est-à-dire, comme cela est visible sur la figure 10, qu'ils sont liés entre eux pour former une pièce amovible 5, destinée à être introduite dans une enveloppe constituée des parois 24 et 30, non visibles.  According to a particular embodiment, the reinforcements 11 are reported in the blade 1, that is to say, as can be seen in FIG. 10, that they are interconnected to form a removable part 5 intended to be introduced into an envelope consisting of walls 24 and 30, not visible.
Les renforts 11 sont disposés parallèlement les uns aux autres, sont reliés par des longerons 50, représentés en traits discontinus, et délimitent deux-à-deux un espace 51.  The reinforcements 11 are arranged parallel to each other, are connected by longitudinal members 50, shown in broken lines, and delimit two-to-two a space 51.
On notera la présence de renforts 11' de dimensions réduites, au nombre de deux entre deux renforts 11 successifs, chacun destiné à être intercalé entre deux trous 23.  It will be noted the presence of reinforcements 11 'of reduced dimensions, two in number between two successive reinforcements 11, each intended to be interposed between two holes 23.
Une telle construction permet avantageusement de simplifier la construction de la lame 1, et notamment le moule permettant sa fabrication. Ainsi, en référence maintenant à la figure 11, on peut voir une pièce 5, comprenant deux longerons 50 et des renforts 11, sur le point d'être assemblée au corps d'une lame 1, en étant introduite entre les parois 24 et 30 de celle-ci, dans une cavité 12 prévue à cet effet. Such a construction advantageously makes it possible to simplify the construction of the blade 1, and in particular the mold allowing its manufacture. Thus, with reference now to FIG. 11, there can be seen a part 5, comprising two longitudinal members 50 and reinforcements 11, about to be assembled to the body of a blade 1, being introduced between the walls 24 and 30. of it, in a cavity 12 provided for this purpose.
De plus cela permet éventuellement que cette pièce 5 soit réalisée dans un matériau aux propriétés différentes, notamment de rigidité .  In addition, it may be possible for this part 5 to be made of a material with different properties, in particular of rigidity.
En référence maintenant à la figure 12, on peut voir dans une variante, une lame 1 plus complexe, qui comporte un dispositif anti-retour de l'eau résiduelle aspirée. Ainsi, chacun des trous 23 communiquent avec un, espace 51 au travers d'un élément anti-retour constitué d'un canal tronconique 52 pratiqué dans la pièce 5, et dont l'orifice le plus grand 53 s'ouvre sur le trou 23 et est de diamètre sensiblement égal, tandis que son orifice le plus petit 54 s'ouvre dans une paroi 55 sur l'espace 51.  Referring now to Figure 12, we can see in a variant, a blade 1 more complex, which comprises a non-return device suctioned residual water. Thus, each of the holes 23 communicate with a space 51 through a non-return element consisting of a frustoconical channel 52 formed in the part 5, and whose largest orifice 53 opens on the hole 23 and is of substantially equal diameter, while its smaller orifice 54 opens into a wall 55 on the space 51.
On comprendra que l'eau résiduelle aspirée se trouve ainsi piégée dans les espaces 51 et ne peut pas retraverser les canaux 52.  It will be understood that the residual water sucked is thus trapped in the spaces 51 and can not cross the channels 52.
