Description

La présente invention concerne un suceur d'aspirateur à poussières, et plus particulièrement une amélioration des performances de dépoussiérage des surfaces de type moquette.The present invention relates to a vacuum cleaner nozzle, and more particularly an improvement in the dust removal performance of carpet-like surfaces.

Tel que représenté figure 1, il est connu, par le document GB 855,613 d'utiliser une règle en caoutchouc de raclage des déchets, ladite règle présentant deux lèvres 139 et 140 articulées autour d'une attache 121. De part et d'autre de cette règle sont disposées des ouvertures mettant en liaison le canal d'écoulement 120 avec le canal d'aspiration 141. Lors du déplacement du suceur 100 selon la direction H, sous l'effet du frottement avec la surface à nettoyer, la lèvre 139 vient obturer l'ouverture 260. L'air est alors aspiré sous le bord avant 132 du suceur.As shown in Figure 1, it is known from GB 855,613 to use a rubber scraping rule, said rule having two lips 139 and 140 articulated around a fastener 121. On either side of this rule are arranged openings connecting the flow channel 120 with the suction channel 141. When the squeegee 100 moves according to the direction H, under the effect of friction with the surface to be cleaned, the lip 139 comes close the opening 260. The air is then sucked under the front edge 132 of the nozzle.

De la sorte, la règle permet, non seulement de rassembler et de racler les poussières sur la surface à nettoyer, mais aussi d'obturer le demi-canal situé à l'arrière de la règle par rapport au sens de déplacement.In this way, the rule allows, not only to collect and scrape the dust on the surface to be cleaned, but also to close the half-channel located at the back of the ruler relative to the direction of travel.

Cependant, si un tel suceur est relativement efficace sur des sols lisses, de type parquet ou carrelage, il est plutôt inefficace pour le nettoyage de sols de type moquette ou tapis où la majeure partie de la poussière est localisée entre les poils de la moquette, ou en liaison physique avec la moquette, de sorte qu'il est difficile, avec un simple flux d'air d'aspiration, de déloger cette poussière.However, if such a nozzle is relatively effective on smooth, parquet or tile, it is rather ineffective for cleaning type floors carpet or rug where most of the dust is localized between carpet pile, or in physical connection to the carpet, so it's difficult, with a simple flow of suction air, to dislodge this dust.

Dans la suite de ce document, on désignera par moquette, tout type de surface composée de fibres et/ou de poils, ces surfaces pouvant être des tapis, revêtements muraux, serviettes, moquettes...In the remainder of this document, all types of surface will be designated by carpet. composed of fibers and / or bristles, these surfaces possibly being carpets, wall coverings, towels, carpets ...

Une amélioration de ce dispositif a été proposé par le Demandeur dans la demande WO 00/65979. Dans ce dispositif, le canal d'aspiration du suceur ouvert vers la surface à nettoyer est séparé en deux par une lame articulée qui, selon le sens de déplacement du suceur prend une position qui, d'une part sollicite la surface à nettoyer, et, d'autre part, obture une portion du canal d'aspiration interne du suceur, la partie active dudit canal étant située à l'arrière de la lame de raclage selon le sens de déplacement du suceur.An improvement of this device was proposed by the Applicant in the WO 00/65979. In this device, the suction channel of the squeegee open towards the surface to be cleaned is separated in two by an articulated blade which, depending on the direction of movement of the squeegee takes a position which, on the one hand stresses the surface to be cleaned, and, on the other hand, closes a portion of the channel internal suction nozzle, the active part of said channel being located at the rear of the scraper blade in the direction of movement of the squeegee.

La lame permet donc de solliciter les fibres du sol pour en déloger les poussières, immédiatement prises dans un courant aéraulique.The blade therefore solicits the soil fibers to dislodge them dust, immediately caught in an air flow.

Ce dispositif fonctionne à satisfaction, mais la disposition de la règle de raclage au milieu du canal d'aspiration, réduisant ainsi par deux la largeur dudit canal, peut provoquer, selon la configuration du suceur, une certaine gêne lors de l'aspiration de déchets volumineux.This device works to satisfaction, but the provision of the scraping rule in the middle of the suction channel, thereby reducing the width of said channel by two, may cause, depending on the nozzle configuration, some discomfort when the suction of bulky waste.

La présente invention vise à améliorer le dispositif présenté sur le principe d'une sollicitation des fibres de la moquette avec une aspiration immédiatement consécutive des poussières mises en suspension, et ce, quel que soit le sens de déplacement du suceur.The present invention aims to improve the device presented on the principle of stressing the carpet fibers with immediate suction of suspended dust, regardless of the direction of displacement of the squeegee.

La présente invention est atteinte à l'aide d'un suceur d'aspirateur présentant au moins un canal d'aspiration ouvert vers la surface à nettoyer, et relié de manière aéraulique à un canal d'écoulement, ledit canal d'aspiration étant sensiblement transversal au sens de déplacement du suceur, ledit suceur comportant au moins une lame susceptible d'être en contact avec la surface à nettoyer, ladite lame étant parallèle audit canal d'aspiration, caractérisé en ce que la lame est agencée à proximité en avant du canal d'aspiration tel que vu par rapport au sens de déplacement du suceur et en ce que cette lame est solidaire de l'extrémité d'un bras dont l'autre extrémité pivote librement autour d'un axe parallèle à ladite lame et situé sensiblement à l'aplomb du canal d'aspiration.The present invention is achieved using a vacuum cleaner nozzle having at least one suction channel open to the surface to be cleaned, and connected air flow to a flow channel, said suction channel being substantially transverse to the direction of movement of the nozzle, said nozzle comprising at least one blade capable of being in contact with the surface to cleaning, said blade being parallel to said suction channel, characterized in that that the blade is arranged close in front of the suction channel as seen relative to the direction of movement of the squeegee and in that this blade is secured to the end of an arm, the other end of which pivots freely around an axis parallel to said blade and located substantially above the canal suction.

Ainsi, lorsque le suceur est avancé, cette lame se rapproche de la surface à nettoyer, sous l'effet de son poids et de son frottement avec la surface.Thus, when the nozzle is advanced, this blade approaches the surface to clean, under the effect of its weight and its friction with the surface.

Le dispositif simplifié tel que présenté garde la spécificité, lors du passage du suceur sur une moquette, d'une sollicitation par raclage des poils de la moquette préalablement à l'aspiration, lesdits poils étant alors écartés par le passage de la lame pour en déloger les poussières, immédiatement prises dans un courant aéraulique.The simplified device as presented retains the specificity, during the passage of the squeegee on a carpet, a solicitation by scraping the hairs of the carpet prior to suction, said bristles then being spread by the passage of the blade to dislodge the dust, immediately taken in an air flow.

Avantageusement, chacune des extrémités de la lame est solidaire d'un bras pivotant, ce qui confère plus de rigidité à ladite lame.Advantageously, each of the ends of the blade is secured to an arm pivoting, which gives more rigidity to said blade.

Avantageusement, la lame comporte des butées d'arrêt de son mouvement de pivotement afin de contrôler l'effet de raclage et de ne pas arc-bouter la lame sous le suceur.Advantageously, the blade has stops to stop its movement of swiveling to control the scraping effect and not to brace the blade under the squeegee.

Préférentiellement, afin de conférer au suceur une symétrie d'efficacité quel que soit le sens de déplacement du suceur, ce dernier comporte deux lames situées en avant et en arrière du canal d'aspiration.Preferably, in order to give the nozzle a symmetry of efficiency whatever either the direction of movement of the squeegee, the latter has two blades located in front of and behind the suction channel.

Avantageusement, les deux lames sont agencées en un cadre délimitant le canal d'aspiration et une partie du canal d'écoulement, ledit cadre étant mobile en pivotement autour d'un axe parallèle aux lames.Advantageously, the two blades are arranged in a frame delimiting the suction channel and part of the flow channel, said frame being movable pivoting about an axis parallel to the blades.

Ainsi, sous l'effet du frottement avec la surface à nettoyer de la lame située en avant du canal d'aspiration selon le sens de déplacement du suceur, ladite lame pivote en se rapprochant vers la surface à nettoyer.Thus, under the effect of friction with the surface to be cleaned of the blade located in before the suction channel in the direction of movement of the squeegee, said blade swivels closer to the surface to be cleaned.

La disposition des lames de raclage au niveau des bords délimitant le canal d'aspiration permet, également par l'adaptation du logement du cadre, de ne pas restreindre la largeur dudit canal au niveau des lames, ce qui est favorable pour l'aspiration et l'écoulement des déchets "volumineux".The arrangement of the scraping blades at the edges delimiting the channel also makes it possible by adapting the housing of the frame to not restrict the width of said channel at the level of the blades, which is favorable for suction and disposal of "bulky" waste.

De plus, la réalisation proposée est aussi efficace que le suceur soit déplacé, perpendiculairement aux lames de raclage, dans un sens ou en sens opposé.In addition, the proposed embodiment is as effective as the nozzle is moved, perpendicular to the scraper blades, in one direction or in the opposite direction.

Enfin, la réalisation d'un sous-ensemble constitué d'un cadre monté en pivotement et dont les bords constituent les lames de raclage permet de ne disposer que d'une seule pièce qui peut être montée facilement dans le canal d'aspiration, ce qui réduit les coûts de fabrication. Finally, the production of a sub-assembly consisting of a frame mounted in pivoting and whose edges constitute the scraper blades allows not have only one piece that can be easily mounted in the channel which reduces manufacturing costs.

Avantageusement, le cadre comporte des butées d'arrêt de son mouvement de pivotement, ce qui permet d'ajuster l'effet recherché d'enfoncement des lames dans la moquette, tout en évitant, par une rotation trop importante, que les lames ne soulèvent trop le suceur, ce qui réduirait son efficacité d'aspiration.Advantageously, the frame has stops to stop its movement of pivoting, which allows to adjust the desired effect of driving the blades in the carpet, while avoiding, by too much rotation, that the boards do not raise the squeegee too much, which would reduce its suction efficiency.

Avantageusement, de telles butées réalisent également l'étanchéité à l'air du suceur à ce niveau, afin d'obliger l'air aspiré à passer sous les lames de raclage.Advantageously, such stops also provide airtightness of the squeegee at this level, in order to force the sucked air to pass under the scraper blades.

Selon une version avantageuse de réalisation, la lame est protubérante d'une hauteur comprise entre un et cinq millimètres lorsque le cadre pivote contre les butées d'arrêt. De telles valeurs permettent de solliciter la moquette en profondeur sans trop augmenter la garde au sol du suceur au niveau du canal d'aspiration, ce qui pourrait être préjudiciable à l'efficacité du suceur. Cette hauteur peut être différente sur chacune des lames afin de différencier l'effet selon le sens de déplacement du suceur.According to an advantageous embodiment, the blade is protruding from a height between one and five millimeters when the frame pivots against the stops. Such values allow the carpet to be stressed in depth without greatly increasing the ground clearance of the squeegee at the canal suction, which could be detrimental to the effectiveness of the nozzle. This height can be different on each of the blades in order to differentiate the effect depending on the direction of movement of the squeegee.

Selon l'un des modes de réalisation, l'axe du cadre est agencé à l'aplomb du canal d'aspiration, ce qui permet aux lames d'avoir un mouvement de rotation plus pénétrant dans la surface à nettoyer.According to one of the embodiments, the axis of the frame is arranged directly above the suction channel, which allows the blades to have a rotational movement more penetrating into the surface to be cleaned.

Avantageusement, l'axe du cadre est agencé dans le plan médian du canal d'aspiration. Cette disposition symétrique permet de procurer l'effet recherché d'une manière analogue selon que le suceur est déplacé dans un sens ou dans l'autre, dans une direction perpendiculaire aux lames de raclage.Advantageously, the axis of the frame is arranged in the median plane of the channel suction. This symmetrical arrangement provides the desired effect in an analogous manner depending on whether the squeegee is moved in one direction or in the other, in a direction perpendicular to the scraper blades.

Selon une variante de réalisation, le suceur dispose de moyens pour modifier sa garde au sol, selon le sens de déplacement dudit suceur. Cette dissymétrie permet d'avoir un niveau d'enfoncement de la lame dans la moquette différent selon le sens de déplacement du suceur, dans le but de provoquer une force de déplacement du suceur par l'utilisateur différente selon le sens de déplacement.According to an alternative embodiment, the nozzle has means for modifying its ground clearance, according to the direction of movement of said nozzle. This asymmetry allows a different level of penetration of the blade into the carpet according to the direction of movement of the squeegee, in order to cause a force of displacement of the squeegee by the user different depending on the direction of movement.

Ce niveau, ou garde au sol, peut être obtenu par un axe de rotation du cadre décentré par rapport au plan médian du canal d'aspiration.This level, or ground clearance, can be obtained by an axis of rotation of the frame off center with respect to the median plane of the suction channel.

Selon une version perfectionnée de l'invention, le cadre dispose d'au moins un canal d'injection ouvert vers la surface à traiter. Il est en effet intéressant, afin d'augmenter l'efficacité du suceur, de pouvoir déloger les poussières des poils de la moquette à l'aide d'un flux d'air localisé.According to an improved version of the invention, the frame has at least one injection channel open to the surface to be treated. It is indeed interesting, so to increase the efficiency of the squeegee, to be able to dislodge the dust from the hairs the carpet using a localized air flow.

Avantageusement, le canal d'injection est situé à l'avant d'au moins une des lames selon le sens de déplacement du suceur, ce qui permet d'associer au mieux l'effet du flux d'air avec l'effet de couchage des poils par l'action de la lame sur lesdits poils. L'air est ainsi soufflé entre les poils écartés par la lame.Advantageously, the injection channel is located at the front of at least one of the blades according to the direction of movement of the squeegee, which allows to associate with the better the effect of the air flow with the coating effect of the hairs by the action of the blade on said hairs. The air is thus blown between the hairs separated by the blade.

Cet effet est renforcé par l'utilisation de moyens de soufflerie reliés au canal d'injection. Ceci procure, lorsque l'aspirateur est mis en marche, une entrée d'air dans la surface à nettoyer sous la forme d'un jet d'air.This effect is reinforced by the use of blower means connected to the channel injection. This provides, when the vacuum cleaner is turned on, an air intake into the surface to be cleaned in the form of an air jet.

En variante ou en complément, le canal d'injection peut être relié à un récipient contenant des produits traitants, tel un lessiviel.As a variant or in addition, the injection channel can be connected to a container containing treatment products, such as detergent.

Avantageusement, le canal d'injection débouche sous la forme de fentes ou de trous régulièrement répartis sur une paroi sensiblement horizontale et attenante le long de la lame, ladite paroi étant située en retrait vers l'intérieur du suceur par rapport à l'extrémité de la lame.Advantageously, the injection channel opens in the form of slots or regularly distributed holes on a substantially horizontal and adjoining wall along the blade, said wall being set back inwards from the nozzle by compared to the end of the blade.

La réalisation de fentes ou de trous régulièrement répartis le long de la lame assure l'homogénéité de l'injection d'air, qui est par ailleurs accéléré au passage des trous ou fentes, pour en améliorer l'efficacité de décrochage des poussières des poils de la moquette.Making slots or holes evenly distributed along the blade ensures the uniformity of the air injection, which is also accelerated in passing holes or slits, to improve the dust release efficiency carpet pile.

Selon l'une des versions envisagées, le suceur dispose, avantageusement, d'un mécanisme permettant d'ajuster la hauteur du cadre dans le conduit d'écoulement et/ou d'aspiration.According to one of the versions envisaged, the squeegee advantageously has a mechanism for adjusting the height of the frame in the duct flow and / or suction.

Ce mécanisme permet, d'une part, de régler en usine la hauteur des lames selon les types de moquette fréquemment rencontrés dans les divers pays, et, d'autre part, il permet à l'utilisateur d'adapter son suceur aux différents types de moquette qu'il peut avoir en sa possession, afin de tirer le meilleur parti de son appareil. This mechanism allows, on the one hand, to adjust the height of the blades in the factory according to the types of carpet frequently encountered in various countries, and, on the other hand, it allows the user to adapt his nozzle to different types of carpet he may have in order to make the most of his apparatus.

Selon des variantes de réalisation, l'extrémité des lames peut être façonnée de manière à provoquer des sollicitations différentes selon le cas de figure rencontrée, voire au sein d'un même suceur. L'extrémité peut ainsi être, soit biseautée, et/ou crénelée, et/ou munie de poils.According to alternative embodiments, the end of the blades can be shaped so as to cause different stresses depending on the scenario encountered, even within the same nozzle. The end can thus be either bevelled, and / or crenellated, and / or provided with bristles.

Avantageusement, le suceur d'aspirateur selon l'invention comporte au moins une bavette d'étanchéité, située à l'avant et/ou à l'arrière du suceur et/ou située à l'avant et/ou à l'arrière du canal d'aspiration, selon le sens de déplacement du suceur, ce qui permet d'augmenter son efficacité. Une telle bavette peut être réalisée en élastomère ou constituée de poils très souples.Advantageously, the vacuum cleaner nozzle according to the invention comprises at least a sealing flap, located at the front and / or rear of the nozzle and / or located at front and / or rear of the suction channel, depending on the direction of movement of the crevice, which increases its efficiency. Such a bib can be made of elastomer or made of very flexible bristles.

En complément du canal d'aspiration muni de lames telles que précédemment définies, le suceur dispose, en outre, d'une ouverture d'aspiration ouverte vers la surface à nettoyer et reliée de manière aéraulique à un canal d'écoulement de l'air aspiré, ladite ouverture d'aspiration étant exempte de lames, permettant ainsi au suceur d'augmenter la surface d'aspiration.In addition to the suction channel provided with blades as above defined, the squeegee also has a suction opening open to the surface to be cleaned and connected aeraulically to a flow channel of the air sucked in, said suction opening being free of blades, thus allowing the nozzle to increase the suction surface.

Un autre objet de la présente invention vise également à la réalisation d'un aspirateur de poussières comportant notamment un groupe moteur susceptible de générer un flux d'aspiration d'air dans des conduits terminés par un suceur ouvert vers la surface à nettoyer, ledit suceur étant conforme à l'une des caractéristiques précédemment énoncées.Another object of the present invention also aims to achieve a dust vacuum cleaner comprising in particular a motor unit capable of generate an air suction flow in conduits terminated by a squeegee open towards the surface to be cleaned, said nozzle being in accordance with one of the previously stated characteristics.

The present invention will be better understood with the aid of the description which follows, with reference to the appended figures, among which:
  • FIG. 1 is a schematic side sectional view of a nozzle of the prior art,
  • FIG. 2 represents the operating principle of the present invention, in a symbolic section view,
  • FIGS. 3 and 4 represent the operating principle of a variant of the present invention, in a schematic view according to a side section,
  • FIG. 5 is a schematic view of a vacuum cleaner nozzle according to an alternative embodiment of the present invention, in a view from below,
  • Figure 6 is an isolated view of the frame and the blades shown in Figure 5, in a bottom view.

En référence à la figure 2, le suceur 1 selon la présente invention, comporte une semelle 3 disposant d'une ouverture définissant un canal d'aspiration 4. Le déplacement habituel du suceur est réalisé selon F1 ou F2. Le sens de déplacement F1 peut être considéré comme un déplacement usuel du suceur vers l'avant, le sens F2 comme un déplacement du suceur vers l'arrière. L'une des caractéristiques principales de l'invention est de disposer d'une règle de raclage en bordure extérieure du canal d'aspiration 4. A titre d'exemple, le suceur de la figure 2 présente deux règles de raclage 5a, 5b situées de part et d'autre du canal d'aspiration 4.Referring to Figure 2, the nozzle 1 according to the present invention comprises a sole 3 having an opening defining a suction channel 4. The usual movement of the squeegee is carried out according to F1 or F2. The meaning of displacement F1 can be considered as usual displacement of the squeegee forward, direction F2 as a displacement of the squeegee backwards. Moon of the main features of the invention is to have a rule of scraping on the outer edge of the suction channel 4. For example, the squeegee in Figure 2 shows two scraping rules 5a, 5b located on either side of the suction channel 4.

Ces règles sont reliées, par un bras oblique, respectivement 7a, 7b, à un axe de pivotement 6a, 6b, le mouvement de rotation des règles s'effectuant selon les arcs de cercle figurés en pointillés sur la figure.These rules are connected, by an oblique arm, respectively 7a, 7b, to an axis of pivoting 6a, 6b, the movement of rotation of the rules being carried out according to the arcs of a circle shown in dotted lines in the figure.

Les axes 6a, 6b de rotation des lames sont préférentiellement situés à proximité du plan médian du canal d'aspiration afin que le pivotement des lames se réalise selon une course qui pénètre franchement les poils de la moquette.The axes 6a, 6b of rotation of the blades are preferably located near of the median plane of the suction channel so that the blades pivot in a course that frankly penetrates the pile of the carpet.

Ainsi, en fonctionnement, lorsque le suceur est déplacé selon la direction F1, la lame 5a, située en avant du canal d'aspiration selon le déplacement du suceur, sous l'effet du frottement avec les poils 11 du sol 8, pivote autour de l'axe 6a en s'enfonçant dans les poils de la moquette selon la flèche indiquée. Ceci provoque un grattage des poils qui favorise l'extraction des poussières immédiatement entraínées par le flux d'aspiration dans le canal d'aspiration.Thus, in operation, when the squeegee is moved in the direction F1, the blade 5a, located in front of the suction channel according to the displacement of the squeegee, under the effect of friction with the bristles 11 of the ground 8, pivots around the axis 6a in sinking into the pile of the carpet according to the arrow indicated. This causes a scraping of the hairs which favors the extraction of dust immediately entrained by the suction flow in the suction channel.

Lorsque le suceur est déplacée dans le sens F2, la lame 5b pivote à son tour, d'une manière analogue à la lame 5a tel que précédemment expliqué. When the squeegee is moved in the direction F2, the blade 5b pivots in turn, in a similar manner to the blade 5a as previously explained.

Il est préférable de prévoir des butées de pivotement des lames afin qu'elles ne s'enfoncent trop dans les poils de la moquette, ce qui pourrait entraíner un basculement de la lame sous le canal d'aspiration.It is preferable to provide pivoting stops for the blades so that they do not get too deep into the pile of the carpet, which could cause tilting of the blade under the suction channel.

Les figures 3 et 4 illustrent de façon schématique le principe général d'une variante de réalisation de l'invention. Le suceur 10, présenté partiellement, comporte des parois 12a et 12b définissant un canal d'écoulement 14 débouchant en un canal d'aspiration 16 ouvert vers la surface à nettoyer.Figures 3 and 4 schematically illustrate the general principle of a variant embodiment of the invention. The nozzle 10, partially presented, has walls 12a and 12b defining a flow channel 14 opening into a suction channel 16 open towards the surface to be cleaned.

La surface 8 à nettoyer est de type moquette et comprend des poils 11 incrustés de poussière 13.The surface 8 to be cleaned is of the carpet type and includes bristles 11 inlaid dust 13.

Plus particulièrement selon l'invention, un cadre 24 est agencé à l'intérieur du canal d'écoulement 14, de telle manière à présenter deux parois 26a, 26b formant un entonnoir et définissant le canal d'aspiration 16.More particularly according to the invention, a frame 24 is arranged inside the flow channel 14, so as to present two walls 26a, 26b forming a funnel and defining the suction channel 16.

L'extrémité des parois 26a, 26b forme respectivement une lame 27a, 27b de raclage en contact avec les poils de la moquette. Le bord inférieur des lames 27a, 27b peut être biseauté si on souhaite un effet de fouet important sur les poils, ou arrondi pour protéger au maximum le sol à nettoyer.The end of the walls 26a, 26b respectively form a strip 27a, 27b of scraping in contact with the carpet pile. The lower edge of the blades 27a, 27b can be beveled if a strong whip effect is desired on the bristles, or rounded to protect the floor to be cleaned as much as possible.

Le cadre 24 est monté en rotation autour d'un axe horizontal 18 parallèle aux lames 27a, 27b. Selon l'exemple proposé, cet axe est sensiblement sur le plan médian du canal d'aspiration. Il peut toutefois être décalé vers l'une des parois 26a, 26b si l'on souhaite que l'action des lames sur le sol soit différente selon le sens de déplacement du suceur.The frame 24 is mounted in rotation about a horizontal axis 18 parallel to the blades 27a, 27b. According to the example proposed, this axis is substantially on the plane median of the suction channel. It can however be shifted towards one of the walls 26a, 26b if it is desired that the action of the blades on the ground be different depending on the direction of movement of the squeegee.

Des butées 30a, 30b, 32a, 32b, permettent de limiter la rotation du cadre. Les butées 30a, 30b sont avantageusement configurées pour coopérer respectivement avec une chicane 34a, 34b ménagée dans les parois correspondantes 26a, 26b afin de garantir l'étanchéité, à ce niveau, du canal d'aspiration. Stops 30a, 30b, 32a, 32b make it possible to limit the rotation of the frame. The stops 30a, 30b are advantageously configured to cooperate respectively with a baffle 34a, 34b formed in the walls 26a, 26b in order to guarantee the tightness, at this level, of the channel suction.

Les chicanes 34a, 34b et/ou les butées 30a, 30b peuvent être garnies d'une mousse, d'un feutre ou d'un joint souple afin d'améliorer cette étanchéité. Il est également possible de surmouler une partie plastique molle à l'extrémité des butées 30a, 30b.The baffles 34a, 34b and / or the stops 30a, 30b can be fitted with a foam, felt or flexible seal to improve this seal. It is also possible to overmold a soft plastic part at the end of the stops 30a, 30b.

La hauteur des lames à l'intérieur du suceur peut être ajustée d'une manière préalable, lors de l'assemblage du suceur, et/ou par l'utilisateur lors du maniement dudit suceur, de telle façon que la lame brosse légèrement les poils ou plus énergiquement, en étant située, lors de la rotation du cadre, par exemple à mi-hauteur des poils, choix dépendant également du type de moquette.The height of the blades inside the squeegee can be adjusted in a way prior to the assembly of the squeegee, and / or by the user during the handling said squeegee so that the blade lightly brushes the hairs or more energetically, by being located, during the rotation of the frame, for example halfway up the pile, choice also depending on the type of carpet.

Par ailleurs, cette commodité permet également de rattraper l'usure de la lame ainsi que de pouvoir monter des plaques de longueur différente en conservant le même suceur.Furthermore, this convenience also makes it possible to compensate for the wear of the blade. as well as being able to mount plates of different lengths while keeping the same sucker.

Il peut être également prévu, par extension, de remonter davantage les lames à l'intérieur du suceur de telle manière à les escamoter et les rendre inactives. Une telle configuration peut être souhaitée lorsque le suceur est utilisé sur sol lisse. Les mécanismes de rentrée et sortie d'une brosse, largement commun sur de nombreux suceurs, peuvent avantageusement être utilisés pour réaliser une telle fonction. Cette opération est par ailleurs facilitée par le fait que les lames sont solidaires du cadre qui peut alors être facilement ajusté en hauteur à l'intérieur du suceur.It can also be provided, by extension, to further raise the blades to inside the squeegee so as to retract them and make them inactive. A such a configuration may be desired when the nozzle is used on smooth ground. The re-entry and exit mechanisms of a brush, widely used on many nozzles, can advantageously be used to achieve such a function. This operation is further facilitated by the fact that the blades are integral with the frame which can then be easily adjusted in height inside the nozzle.

Comme on peut le constater sur les figures 3 et 4, le cadre, lorsque le suceur est déplacé selon la direction F1 ou F2, pivote autour de l'axe 18, guidé par les butées 30a, 30b. L'effet des frottements des lames conjugué à la position de l'axe 18 de pivotement du cadre, provoque, selon la direction de déplacement F1 ou F2 du suceur, respectivement une rotation du cadre selon G1 et G2 jusqu'à venir contre les butées respectives 32b, 32a. Cette rotation entraíne un enfoncement de la lame située à l'avant du canal d'aspiration selon le sens de déplacement du suceur. Les poils de la moquette sont alors agités par la lame de raclage ce qui favorise l'extraction des poussières derrière cette lame de raclage. Ces poussières sont alors immédiatement récupérées par l'aspiration.As can be seen in Figures 3 and 4, the frame, when the nozzle is moved in direction F1 or F2, pivots around axis 18, guided by stops 30a, 30b. The effect of the friction of the blades combined with the position of the pivot axis 18 of the frame, causes, in the direction of movement F1 or F2 of the squeegee, respectively a rotation of the frame according to G1 and G2 until come against the respective stops 32b, 32a. This rotation results in a sinking of the blade located in front of the suction channel in the direction of displacement of the squeegee. The pile of the carpet is then agitated by the blade of scraping which promotes the extraction of dust behind this scraper blade. This dust is then immediately collected by suction.

Un tel effet se produit, que le suceur soit déplacé selon la direction F1 ou selon la direction F2.Such an effect occurs whether the squeegee is moved in the direction F1 or in the direction direction F2.

Selon une caractéristique de la présente invention, la rotation du cadre 24 autour de l'axe de pivotement 18 peut être symétrique ou dissymétrique afin d'obtenir un effet de raclage différent selon le sens de déplacement du suceur. Cette dissymétrie peut être réalisée par un positionnement ou un dimensionnement judicieux des butées et/ou un décentrage de l'axe de rotation du cadre dans le canal d'aspiration et/ou d'écoulement. Des dispositifs permettant un tel effet sont largement présentés dans le document WO 00/65979 au nom du Demandeur.According to a characteristic of the present invention, the rotation of the frame 24 around of the pivot axis 18 can be symmetrical or asymmetrical in order to obtain a different scraping effect depending on the direction of movement of the squeegee. This asymmetry can be achieved by positioning or sizing judicious stops and / or a decentering of the axis of rotation of the frame in the suction and / or flow channel. Devices allowing such an effect are widely presented in document WO 00/65979 in the name of the Applicant.

Selon une variante de réalisation présentée aux figures 5 et 6, le suceur comporte au moins un canal d'injection d'air ouvert vers la surface à traiter par l'intermédiaire de trous.According to an alternative embodiment presented in Figures 5 and 6, the squeegee has at least one air injection channel open to the surface to be treated by through holes.

La structure particulière de réalisation de l'invention illustrée figure 5 est agencée, à titre d'exemple, sur un suceur 40 de forme triangulaire, présentant une embouchure d'aspiration avant 42, prolongée par deux canaux latéraux 44 et 46. Un canal d'aspiration 43 situé à l'arrière du suceur est délimité par un cadre 54 tel que précédemment décrit, et dont l'axe, 58, est monté en rotation dans une pièce 60 formant palier. Sur cette figure sont également visibles les emplacements 48 pour les bandes arrache fils, la zone 50 de réception d'un patin de glissement, ainsi que le logement 52 pour des roues de déplacement du suceur.The particular structure for carrying out the invention illustrated in FIG. 5 is arranged, for example, on a nozzle 40 of triangular shape, having a front suction mouth 42, extended by two lateral channels 44 and 46. A suction channel 43 located at the rear of the nozzle is delimited by a frame 54 as previously described, and whose axis, 58, is mounted in rotation in a part 60 forming a bearing. In this figure are also visible the slots 48 for the tear-off strips, the area 50 for receiving a sliding shoe, as well as the housing 52 for displacement wheels of the squeegee.

On retrouve dans le cadre 54, tel que détaillé figure 6, les parois 56a, 56b délimitant principalement le canal d'aspiration et dont les extrémités respectives 57a, 57b constituent les lames de raclage telles que précédemment caractérisées. Un tel cadre comporte, par ailleurs, au niveau de la lame 57a, un conduit 62 d'injection d'air et/ou de produit traitant, orienté vers l'extérieur du cadre et s'étendant sur toute la longueur de la lame.Found in box 54, as detailed in FIG. 6, the walls 56a, 56b mainly delimiting the suction channel and whose respective ends 57a, 57b constitute the scraper blades as above characterized. Such a frame also comprises, at the level of the blade 57a, a duct 62 for injecting air and / or treating product, oriented towards the outside of the frame and extending over the entire length of the blade.

Ce conduit d'injection est relié à un circuit d'injection ménagé à l'intérieur du suceur. Il débouche sous la forme de fentes ou de trous 64 régulièrement répartis, lesdits trous étant situés à proximité de la lame de raclage 57a.This injection pipe is connected to an injection circuit arranged inside the nozzle. It opens out in the form of slots or holes 64 regularly distributed, said holes being located near the scraper blade 57a.

Cette particularité permet un effet de jet où l'air prend une vitesse dirigée parallèlement à l'axe des trous. L'air pénètre ainsi plus profondément au coeur de la moquette et peut atteindre le fond de la moquette, qui est un endroit difficile d'accès, et donc difficile à nettoyer.This characteristic allows a jet effect where the air takes a directed speed parallel to the axis of the holes. The air thus penetrates deeper into the heart carpet and can reach the bottom of the carpet which is a place difficult to access, and therefore difficult to clean.

De plus, le flux d'air se trouve orienté dans une direction établie par la position de la lame ce qui permet de diriger l'entrée d'air de façon moins restrictive et pouvant aller jusqu'à la verticale.In addition, the air flow is oriented in a direction established by the position of the blade which allows to direct the air intake in a less restrictive way and up to vertical.

Le choix de la forme (entrée d'air unique ou multiple, plusieurs trous...) et de la section de passage de cette entrée d'air permettent de canaliser une énergie aéraulique agissant au niveau de la lame de raclage, mais pouvant agir également dans le fond de la moquette pour y décoller les poussières.The choice of shape (single or multiple air inlet, several holes ...) and the passage section of this air inlet allow energy to be channeled ventilation acting on the scraper blade, but able to act also in the bottom of the carpet to remove dust.

Il est important de noter que le présent dispositif peut être associé à une aspiration dite "classique", c'est à dire sans lame de raclage, et représentée par l'ouverture 42 présentée à la figure 5.It is important to note that the present device can be associated with a so-called "classic" suction, that is to say without a scraper blade, and represented by the opening 42 presented in FIG. 5.

Cette association permet de créer une synergie entre une aspiration de surface, capable de débarrasser la surface de la moquette des déchets les plus encombrants et les plus accessibles, tout en permettant une action en profondeur par le dispositif présenté.This association makes it possible to create a synergy between a surface aspiration, able to rid the surface of the carpet of the most waste bulky and the most accessible, while allowing action in depth by the device presented.

Le canal d'injection peut être relié, selon une première configuration, à l'extérieur du suceur. Ainsi, le suceur possède des orifices d'entrée d'air permettant d'injecter de l'air pris à l'extérieur du suceur dans la surface à nettoyer. The injection channel can be connected, according to a first configuration, to the outside of the squeegee. Thus, the squeegee has air inlet holes allowing inject air taken from outside the nozzle into the surface to be cleaned.

Selon une deuxième réalisation, le canal d'injection est relié à un récipient contenant des produits traitants, soit à part entière soit en association avec une entrée d'air extérieur, comme précédemment décrit. Les produits traitants utilisés peuvent être sous forme liquide, pulvérulente, ou bien sous la forme d'aérosols,... Il est alors possible de combiner une action mécanique d'amenée d'air et une action physico-chimique par le produit traitant de la moquette.According to a second embodiment, the injection channel is connected to a container containing treatment products, either in their own right or in association with a outside air intake, as previously described. The treatment products used can be in liquid, powdered form, or in the form aerosols, ... It is then possible to combine a mechanical supply action of air and a physicochemical action by the product treating the carpet.

Il est tout à fait envisageable, sans sortir du cadre de la présente invention, d'amener de l'air chaud par ce canal, air pouvant être généré par des moyens de soufflerie pouvant comporter un circuit spécifique de chauffage. Il est alors intéressant, dans ce cas de figure, de collecter l'air à la sortie moteur. Cet air permet, par exemple, de sécher une moquette.It is entirely possible, without departing from the scope of the present invention, to bring hot air through this channel, air which can be generated by means of blower which may include a specific heating circuit. So he is interesting, in this case, to collect the air at the engine outlet. This air allows, for example, to dry a carpet.

De plus, la forme du canal ainsi que celle des ouvertures dudit canal vers la surface à traiter peuvent être adaptées pour que l'air sorte sous la forme d'une lame d'air, ce qui permet d'avoir une meilleure efficacité dans le séchage de la moquette et/ou le décollement de la poussière incrustée dans les fibres de la moquette.In addition, the shape of the channel as well as that of the openings of said channel towards the surface to be treated can be adapted so that the air comes out in the form of a air gap, which allows better efficiency in drying the carpet and / or the removal of dust embedded in the fibers of the carpet.
