Description

La présente invention concerne de manière générale un suceur d'aspirateur dont la semelle est reliée au raccord vers la crosse par une bielle d'articulation.The present invention generally relates to a vacuum nozzle whose sole is connected to the connection to the butt by a connecting rod.

Il est connu dans l'art antérieur des suceurs d'aspirateur dont la semelle est articulée pour s'adapter aux éléments en relief disposés sur le sol à nettoyer. Par exemple, le document EP0304609 décrit un suceur d'aspirateur dont la semelle est reliée en rotation à un patin, lui-même relié à la crosse d'aspiration par des biellettes d'articulation. Ce mécanisme permet de provoquer le basculement de la semelle d'aspiration dans un sens ou dans l'autre quand le suceur est poussé ou tiré par l'utilisateur. Ce basculement présente l'inconvénient de provoquer des fuites d'air du côté soulevé, diminuant la dépression dans le canal d'aspiration, ce qui affecte l'efficacité du grattage si le sol est recouvert de moquette car la force de dépression qui plaque la semelle au sol est diminuée. On entend par grattage l'action mécanique de la semelle sur les poils du sol textile qui doit être nettoyé.It is known in the prior art suction nozzles whose sole is hinged to fit the raised elements disposed on the floor to be cleaned. For example, the document EP0304609 describes a suction nozzle whose sole is rotatably connected to a pad, itself connected to the suction grip by connecting rods. This mechanism makes it possible to cause the suction pad to tilt in one direction or the other when the nozzle is pushed or pulled by the user. This tilting has the disadvantage of causing air leakage on the raised side, decreasing the vacuum in the suction channel, which affects the effectiveness of scraping if the floor is carpeted because the vacuum force that plates the ground sole is diminished. Scraping is understood to mean the mechanical action of the sole on the hairs of the textile floor to be cleaned.

Le document EP0125994 présente lui aussi un suceur dont la semelle d'aspiration est articulée par rapport à une buse basculante. Le suceur comporte aussi un galet ou un patin d'appui qui reprend les efforts de l'utilisateur en marche avant et qui permet de limiter l'effet de bascule de la semelle. Par contre, en marche arrière, le galet ou le patin n'ont plus aucun effet et rien n'empêche la semelle de basculer, de sorte qu'une fuite d'air est occasionnée du côté se soulevant, limitant la force de plaquage au sol et donc l'efficacité du grattage. Ceci peut intervenir si l'utilisateur ne fait que tirer la crosse d'un seule main ou peut même être amplifié si celui-ci tient la crosse des deux mains et applique un effort vers l'arrière pour tirer et un effort vers le bas pour plaquer le galet au sol. Afin de limiter cet effet de bascule, un verrou actionnable par l'utilisateur est prévu entre la semelle et la buse basculante. Un tel dispositif est compliqué à réaliser car ce mécanisme comporte plusieurs pièces à assembler. Par ailleurs, ce dispositif est néfaste à l'ergonomie du dispositif complet car l'utilisateur doit lui-même commander le verrou s'il constate que l'aspiration n'est pas optimale en marche arrière. De plus, le verrou, une fois enclenché, supprime tout degré de liberté à la semelle et celle-ci perd son caractère articulé et ne peut plus s'adapter aux irrégularités du sol en marche avant. L'utilisateur, à la limite, doit verrouiller la semelle en marche arrière et déverrouiller en marche avant, ce qui est particulièrement fastidieux car il faut le faire à chaque aller-retour.The document EP0125994 also has a suction nozzle whose suction sole is articulated with respect to a tilting nozzle. The nozzle also comprises a roller or a support pad which takes the efforts of the user forward and which limits the toggle effect of the sole. By cons, in reverse, the roller or the skate have no effect and nothing prevents the sole from tilting, so that an air leak is caused on the lifting side, limiting the plating force to soil and thus the effectiveness of scratching. This can happen if the user only pulls the butt with one hand or can even be amplified if the latter holds the stock with both hands and applies a force to the back to shoot and a downward effort to press the roller on the ground. In order to limit this rocking effect, a user-actuable lock is provided between the sole and the tilting nozzle. Such a device is complicated to achieve because this mechanism has several parts to assemble. Moreover, this device is detrimental to the ergonomics of the complete device because the user must himself control the lock if he finds that the suction is not optimal in reverse. In addition, the latch, once engaged, removes any degree of freedom to the sole and it loses its articulated nature and can no longer adapt to the irregularities of the ground in the forward direction. The user, at the limit, must lock the sole in reverse and unlock forward, which is particularly tedious because it must be done every round trip.

Un but de la présente invention est de répondre aux inconvénients des documents de l'art antérieur mentionnés ci-dessus et en particulier, tout d'abord, de proposer un suceur de construction simple comportant une semelle articulée permettant un usage en marche avant ou en marche arrière sans fuite d'air sous la semelle pouvant affecter l'efficacité d'aspiration.An object of the present invention is to meet the disadvantages of the documents of the prior art mentioned above and in particular, first of all, to propose a simple construction nozzle having an articulated soleplate allowing use in forward motion or in reverse without air leakage under the soleplate that may affect the suction efficiency.

Pour cela un premier aspect de l'invention concerne un suceur d'aspirateur comportant une semelle reliée en rotation par une bielle à une pièce de raccord vers l'aspirateur, au moins une roue d'appui sur le sol montée sur la bielle, la semelle comportant au moins un canal d'aspiration du sol délimité à l'avant et à l'arrière par des arêtes de grattage, caractérisé en ce que la semelle, à l'arrière des arêtes de grattage, comporte en outre des moyens de butée sur le sol limitant la rotation de la semelle autour de la bielle lors des déplacements arrières du suceur d'aspirateur et en ce que les moyens de butée sont agencés pour permettre le passage de l'air vers l'arête arrière de grattage. L'invention permet ainsi une aspiration efficace en marche arrière car, grâce aux moyens de butée, le basculement intempestif de la semelle est limité, ce qui évite de perdre l'efficacité d'aspiration avec des fuites d'air. En marche arrière, quelle que soit l'action de l'utilisateur sur la crosse (simple traction ou efforts de traction et de poussée vers le bas combinés), le basculement est limité car les moyens de butée sont agencés directement sur la semelle flottante. Enfin, le basculement n'étant limité que lors des déplacements arrières, la semelle conserve complètement sa capacité de mouvement pour s'adapter aux irrégularités en marche avant et peut s'adapter aux petites irrégularités lors des mouvement en marche arrière. Toujours dans l'optique de ne pas nuire à l'efficacité d'aspiration, les moyens de butée selon l'invention sont disposés de manière à ne pas compromettre le flux d'air aspiré vers l'arête arrière de grattage.For this purpose, a first aspect of the invention relates to a suction nozzle comprising a soleplate connected in rotation by a connecting rod to a connecting piece towards the vacuum cleaner, at least one support wheel on the ground mounted on the connecting rod, the soleplate having at least one floor suction channel defined at the front and rear by scraping edges, characterized in that the sole, behind the scraping edges, further comprises stop means on the ground limiting the rotation of the sole around the connecting rod during the rearward movements of the vacuum nozzle and in that the stop means are arranged to allow the passage of air to the rear edge of scraping. The invention thus allows effective suction in reverse because, thanks to the abutment means, inadvertent tilting of the sole is limited, which avoids losing the suction efficiency with air leaks. In reverse, regardless of the action of the user on the butt (single pull or combined pulling and pushing forces down), the tilting is limited because the stop means are arranged directly on the flange. Finally, the tilting is limited only when moving back, the sole completely retains its ability to movement to adapt to irregularities in the forward direction and can adapt to small irregularities when moving in reverse. Still with a view to not adversely affect the suction efficiency, the abutment means according to the invention are arranged so as not to compromise the flow of air sucked to the rear scraping edge.

De manière avantageuse, les arêtes de grattage définissent un plan de grattage, et les moyens de butée forment une surface d'appui surélevée par rapport au plan de grattage et séparée de l'arête arrière de grattage par un passage d'air. De manière simple, la valeur maximale de pivotement de la semelle lors d'un déplacement arrière est donnée par la distance verticale séparant le plan de grattage de la surface d'appui, de sorte que la règle avant de grattage ne peut pas se soulever d'une valeur trop importante qui occasionnerait les fuites néfastes à l'aspiration.Advantageously, the scraping edges define a scraping plane, and the stop means form a raised bearing surface with respect to the scraping plane and separated from the rear scraping edge by an air passage. In a simple manner, the maximum pivoting value of the soleplate during a rearward movement is given by the vertical distance separating the scraping plane from the bearing surface, so that the front scraping rule can not lift itself off. too high a value which would cause harmful leakage to the suction.

Avantageusement, les moyens de butée définissent un deuxième plan qui forme avec le premier plan un angle dont le sommet est l'arête arrière de grattage. Cette géométrie permet de garantir que lors des déplacements arrières, tout en ayant un pivotement possible, lorsque la surface d'appui est en contact avec le sol, la résistance au recul sera limitée car la surface d'appui et l'arête arrière de grattage sont alignées.Advantageously, the stop means define a second plane which forms with the first plane an angle whose apex is the rear scraping edge. This geometry makes it possible to guarantee that during rearward movements, while having a possible pivoting, when the bearing surface is in contact with the ground, the resistance to recoil will be limited because the bearing surface and the rear edge of scraping are aligned.

Avantageusement, aux extrémités du suceur, la largeur du passage d'air entre l'arête arrière de grattage et les moyens de butée est au moins égale à 5% de la longueur du canal d'aspiration. Les moyens de butée ne doivent pas perturber les flux d'air vers l'arête arrière de grattage et il faut prévoir au minimum cette valeur pour permettre à l'air de circuler librement. La demanderesse a constaté que cette valeur représentait le bon compromis pour satisfaire les impératifs de la mécanique des fluides (vitesse, caractéristique d'écoulement, perte de charge) et les contraintes géométriques d'encombrement total de la semelle du suceur.Advantageously, at the ends of the nozzle, the width of the air passage between the rear scraping edge and the abutment means is at least equal to 5% of the length of the suction channel. The stop means must not disturb the air flow to the rear scraping edge and it must be provided at least this value to allow the air to circulate freely. The Applicant has found that this value represents the right compromise to meet the requirements of fluid mechanics (speed, flow characteristic, pressure drop) and geometric constraints total space of the sole of the nozzle.

Une réalisation particulièrement intéressante consiste en ce que les moyens de butée sont formés par deux surfaces d'appui agencées à chaque extrémité du suceur et à l'arrière des arêtes de grattage, reliées par une liaison. On obtient ainsi un système stable car les deux appuis sur le sol sont éloignés l'un de l'autre.A particularly interesting embodiment is that the abutment means are formed by two bearing surfaces arranged at each end of the nozzle and at the rear of the scraping edges, connected by a link. This gives a stable system because the two supports on the ground are distant from each other.

Avantageusement, la liaison de la semelle des surfaces d'appui comporte des passages d'air vers la règle arrière de grattage. Ces passages d'air s'ajoutent à la rainure agencée entre l'arête arrière de grattage et les moyens de butée.Advantageously, the connection of the sole of the bearing surfaces comprises air passages to the rear scraping rule. These air passages are added to the groove arranged between the rear scraping edge and the abutment means.

Avantageusement, la liaison de la semelle entre les deux surfaces d'appui est surélevée par rapport aux surfaces d'appui pour laisser passer l'air aspiré par le suceur vers l'arête arrière de grattage. En complément du passage d'air entre l'arête arrière de grattage et les moyens de butée, cet évidement garanti que l'air est correctement aspiré tout le long de l'arête arrière de grattage.Advantageously, the connection of the soleplate between the two bearing surfaces is raised relative to the bearing surfaces to allow the air sucked by the nozzle to pass to the rear scraping edge. In addition to the passage of air between the rear scraping edge and the abutment means, this recess ensures that the air is correctly sucked all along the rear scraping edge.

Avantageusement, les contours de la surface d'appui sont chanfreinés et/ou rayonnés. Cela permet de limiter la résistance au mouvement lorsque les moyens de butée sont en contact avec le sol lors d'un mouvement du suceur en marche arrière.Advantageously, the contours of the bearing surface are chamfered and / or radiated. This limits the resistance to movement when the abutment means are in contact with the ground during a movement of the nozzle in reverse.

Un second aspect de l'invention est un aspirateur comportant au moins un suceur selon le premier aspect de l'invention.A second aspect of the invention is a vacuum cleaner comprising at least one nozzle according to the first aspect of the invention.

D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement à la lecture de la description détaillée qui suit de modes de réalisation de l'invention donnés à titre d'exemples nullement limitatifs et illustrés par les dessins annexés, dans lesquels :

  • la figure 1 représente un suceur d'aspirateur selon l'invention ;
  • la figure 2 représente le suceur de la figure 1 lors d'un mouvement normal vers l'arrière ;
  • la figure 3 représente un détail de la semelle d'aspiration du suceur de la figure 1 utilisé dans des conditions normales en marche avant ou arrière ;
  • la figure 4 représente le détail de la figure 3 de la semelle d'aspiration du suceur utilisé dans des conditions particulières en marche arrière.
Other features and advantages of the present invention will appear more clearly on reading the following detailed description of embodiments of the invention given as non-limiting examples and illustrated by the appended drawings, in which:
  • the figure 1 represents a suction nozzle according to the invention;
  • the figure 2 represents the sucker of the figure 1 during normal backward movement;
  • the figure 3 represents a detail of the suction sole of the nozzle of the figure 1 used under normal conditions in forward or reverse;
  • the figure 4 represents the detail of the figure 3 the suction pad of the nozzle used in particular conditions in reverse.

La figure 1 représente un suceur d'aspirateur 100 comportant une semelle d'aspiration 10 reliée en rotation à un raccord 40 vers la crosse (non représentée) par l'intermédiaire d'une bielle 20 et d'un flexible 30. La semelle 10 comporte une fente (ou canal) d'aspiration 13 délimitée à l'avant et à l'arrière par des règles de grattage. Chaque règle de grattage consiste essentiellement en une arête de grattage reliée à un chanfrein d'attaque. La bielle 20 comporte au moins un galet 50 d'appui au sol 200 qui tourne autour d'un axe 23. La semelle peut tourner autour de l'axe de rotation 21 de la bielle et celle-ci peut aussi tourner en rotation autour de l'axe de rotation 22 qui la relie au raccord 40. La semelle articulée 10, ainsi rendue flottante par rapport au raccord 40 peut aisément s'adapter aux inégalités du sol 200, rendant la tâche de nettoyage plus aisée, malgré la force de plaquage sur la semelle 10 créée par la dépression d'aspiration sur toute la surface du canal d'aspiration 13. En complément, lors des mouvements vers l'avant du suceur, le galet 50 reprend les efforts verticaux transmis par l'utilisateur et seuls les efforts horizontaux sont transmis à la semelle 10, de sorte qu'elle peut franchir des obstacles sans blocage ni basculement ou arc-boutement dus aux efforts verticaux de l'utilisateur. Ainsi, deux arêtes de grattage 11 et 12 du canal d'aspiration 13 restent en contact avec le sol 200, garantissant une aspiration sans fuite intempestive dans le canal d'aspiration, ce qui permet un nettoyage efficace.The figure 1 is a suction nozzle 100 having a suction pad 10 rotatably connected to a connector 40 to the butt (not shown) via a rod 20 and a hose 30. The sole 10 has a slot (or channel) suction 13 delimited at the front and rear by scraping rules. Each scraping rule consists essentially of a scraping edge connected to a leading chamfer. The connecting rod 20 comprises at least one ground support roller 50 which rotates about an axis 23. The soleplate can rotate about the axis of rotation 21 of the connecting rod and the rod can also turn in rotation around the axis of rotation 22 which connects it to the coupling 40. The hinged soleplate 10, thus made floating relative to the connector 40 can easily adapt to the unevenness of the ground 200, making the cleaning task easier, despite the plating force on the sole 10 created by the vacuum suction over the entire surface of the suction channel 13. In addition, during the forward movements of the nozzle, the roller 50 takes up the vertical forces transmitted by the user and only the horizontal forces are transmitted to the sole 10, so that it can overcome obstacles without blocking or tilting or arching due to the vertical forces of the user. Thus, two scraping edges 11 and 12 of the suction channel 13 remain in contact with the ground 200, ensuring suction without inadvertent leakage in the suction channel, which allows effective cleaning.

La figure 2 représente le suceur 100 lors d'un mouvement en marche arrière lorsque l'utilisateur tient la crosse à une hauteur normée (i.e. 800 mm du sol) et prédéterminée : la roue 50 se soulève du sol et le positionnement de l'axe 21 par rapport au canal d'aspiration 13 permet dans ce cas de garantir que la direction de la force appliquée par la bielle 20 sur la semelle 10, en combinaison avec la force de plaquage créée par la dépression d'aspiration, ne provoque pas de basculement intempestif de la semelle 10, ce qui aurait pour effet de créer une fuite d'air provoquant une diminution de la dépression, donc de la force de plaquage et de l'efficacité de grattage.The figure 2 represents the squeegee 100 during a movement in reverse when the user holds the stock at a standard height (ie 800 mm from the ground) and predetermined: the wheel 50 is lifted from the ground and the positioning of the axis 21 relative the suction channel 13 in this case ensures that the direction of the force applied by the rod 20 on the sole 10, in combination with the plating force created by the suction vacuum, does not cause inadvertent tilting of the sole 10, which would have the effect of creating an air leak causing a decrease in the depression, so the plating force and scraping efficiency.

La figure 3 représente en détail la semelle 10 lorsque le suceur est poussé en marche avant ou est tiré en marche arrière dans les conditions normées de la figure 2. La semelle 10 est en contact avec le sol 200 par les deux arêtes de grattage 11 et 12, ce qui garantit qu'il n'y pas de fuites d'air intempestives, de sorte que l'efficacité d'aspiration est optimale. Pour ne pas perturber le fonctionnement dans ces conditions normales d'utilisation, une surface d'appui 15 ne doit pas toucher le sol et à cet effet, elle est surélevée par rapport au sol au minimum d'une distance d1. La surface d'appui 15 est par ailleurs inclinée par rapport au sol 200, ou au plan de grattage qui contient les deux arêtes de grattage 11 et 12. L'inclinaison par rapport au plan de grattage est choisie pour que le plan contenant la surface d'appui 15 comprenne le point le plus bas de la partie arrière de grattage, c'est-à-dire l'arête arrière de grattage 12. La raison du choix de l'angle α en fonction de ce critère sera expliquée au paragraphe relatif à la figure 4.The figure 3 represents in detail the sole 10 when the squeegee is pushed forward or is pulled backwards under the standard conditions of the figure 2 . The sole 10 is in contact with the ground 200 by the two scraping edges 11 and 12, which ensures that there is no untimely air leakage, so that the suction efficiency is optimal. In order not to disturb the operation under these normal conditions of use, a bearing surface 15 must not touch the ground and for this purpose it is raised above the ground by at least a distance d1. The bearing surface 15 is also inclined relative to the ground 200, or to the scraping plane which contains the two scraping edges 11 and 12. The inclination with respect to the scraping plane is chosen so that the plane containing the surface 15 includes the lowest point of the rear scraping portion, that is to say the rear scraping edge 12. The reason for choosing the angle α according to this criterion will be explained in paragraph relating to figure 4 .

La figure 4 représente la semelle 10 lorsque le suceur 100 est déplacé vers l'arrière, en dehors des conditions normées de la figure 2. Par exemple, l'utilisateur tire vers l'arrière le suceur 100 mais exerce simultanément sur le suceur un effort vertical vers le bas. Dans cette configuration; l'architecture du suceur provoque alors sur la semelle 10 un couple de renversement et celui-ci pourrait avoir pour effet de décoller du sol 200 l'arête avant de grattage 11. Pour éviter cette situation et préserver le couple pression-débit, la surface d'appui 15 vient en contact avec le sol 200 et limite le basculement de la semelle 10 à un pivotement maximal. En conséquence, l'arête de grattage avant 11 ne peut pas se soulever plus haut que ce pivotement maximal tel que représenté sur la figure 4, limitant le débit de la fuite d'air sous l'arête avant 11. Par ailleurs, la présence de la surface d'appui 15 ne doit pas compromettre le débit d'air entrant par l'arête arrière de grattage et c'est pourquoi un passage d'air 16 est ménagé entre l'arête arrière de grattage 12 et le patin d'appui 15. Ce passage 16 doit avoir une largeur maximale aux deux extrémités du suceur 100 car c'est à ces endroits que le débit y est le plus important. Enfin, lors des déplacements vers l'arrière, lorsque le patin 15 vient en appui sur le sol, il faut limiter les efforts de résistance au mouvement. A cet effet, la surface d'appui 15 est alignée avec le point le plus bas de la règle arrière de grattage, à savoir l'arête arrière de grattage 12. Il en ressort que la surface d'appui 15 forme avec le plan de grattage un angle α dont le sommet est l'arête arrière de grattage 12. De cette manière, lors des mouvements vers l'arrière, il n'y a aucun élément de la semelle 10 en saillie vers le sol, entre la surface d'appui 15 et l'arête de grattage arrière 12, et qui pourrait exercer une résistance au glissement de la semelle sur le sol. En complément, les bords de la surface d'appui 15 sont rayonnés ou chanfreinés, toujours dans l'optique de limiter les efforts s'opposant au déplacement du suceur 100.The figure 4 represents the sole 10 when the nozzle 100 is moved backwards, outside the standardized conditions of the figure 2 . For example, the user pulls back the nozzle 100 but simultaneously exerts on the nozzle a vertical effort down. In this configuration; the architecture of the nozzle then causes on the sole 10 a reversal torque and it could have the effect of taking off from the ground 200 the edge before scratching 11. To avoid this situation and preserve the pressure-flow torque, the surface support 15 comes into contact with the ground 200 and limits the tilting of the soleplate 10 to a maximum pivoting. As a result, the front scraping edge 11 can not lift higher than this maximum pivoting as shown in FIG. figure 4 , limiting the flow of the air leak under the front edge 11. Moreover, the presence of the bearing surface 15 must not compromise the air flow entering the rear scraping edge and it is why an air passage 16 is provided between the rear scraping edge 12 and the support pad 15. This passage 16 must have a maximum width at both ends of the nozzle 100 because it is in these places that the flow there is the most important. Finally, when moving backwards, when the pad 15 bears on the ground, it is necessary to limit resistance efforts to movement. For this purpose, the bearing surface 15 is aligned with the lowest point of the rear scraping rule, namely the rear scraping edge 12. It follows that the bearing surface 15 forms with the plane of scraping an angle α whose vertex is the rear scraping edge 12. In this way, during rearward movements, there is no element of the sole 10 projecting towards the ground, between the surface of support 15 and the rear scraping edge 12, and which could exert resistance to sliding of the sole on the ground. In addition, the edges of the bearing surface 15 are radiated or chamfered, always with the aim of limiting the forces opposing the displacement of the nozzle 100.
