Description

La présente invention relève du domaine des équipements pour piscines. Elle concerne plus particulièrement un appareil de nettoyage de piscine autonome de type robot.The present invention relates to the field of equipment for swimming pools. It relates more particularly to an autonomous swimming pool cleaning device of the robot type.

Préambule et art antérieurPreamble and prior art

L'invention concerne un appareil nettoyeur de surface immergée dans un liquide, telle qu'une surface formée par les parois d'un bassin, notamment d'une piscine. Il s'agit notamment d'un robot mobile de nettoyage de piscine. Un tel robot de nettoyage réalise ledit nettoyage en parcourant le fond et les parois du bassin de la piscine, en brossant ces parois, et en aspirant les débris vers un filtre. On désigne par débris toutes les particules présentes au sein du bassin, telles que morceaux de feuilles, microalgues, etc., ces débris étant normalement déposés au fond du bassin ou collés sur les parois latérales de celui-ci.The invention relates to an apparatus for cleaning a surface immersed in a liquid, such as a surface formed by the walls of a basin, in particular of a swimming pool. It is in particular a mobile swimming pool cleaning robot. Such a cleaning robot performs said cleaning by traversing the bottom and the walls of the swimming pool basin, by brushing these walls, and by sucking the debris towards a filter. Debris denotes all the particles present within the basin, such as pieces of leaves, microalgae, etc., this debris being normally deposited at the bottom of the basin or stuck on the side walls of the latter.

Le plus couramment, le robot est alimenté en énergie par un câble électrique reliant le robot à une unité extérieure de commande et d'alimentation.Most commonly, the robot is supplied with energy by an electric cable connecting the robot to an external control and power unit.

On connaît, par exemple, dans ce domaine, les brevets FR 2 925 557 et 2 925 551 , de la demanderesse, qui visent un appareil nettoyeur de surface immergée à dispositif de filtrage démontable. De tels dispositifs comprennent un corps, des organes d'entraînement dudit corps sur la surface immergée, une chambre de filtration ménagée au sein du corps et comportant une entrée de liquide, une sortie de liquide, un circuit hydraulique de circulation de liquide entre l'entrée et la sortie à travers un dispositif de filtrage.We know, for example, in this field, the patents FR 2 925 557 and 2 925 551 , by the Applicant, which are aimed at an immersed surface cleaning apparatus with a removable filtering device. Such devices include a body, members for driving said body on the submerged surface, a filtration chamber formed within the body and comprising a liquid inlet, a liquid outlet, a hydraulic circuit for circulating liquid between the body. inlet and outlet through a filter device.

On connait, également dans ce domaine, la demande de brevet WO201161389 , de la demanderesse, qui divulgue un appareil de nettoyage de piscine comportant un organe en saillie de sa base solidaire d'un organe antiblocage rotatif positionné devant lui selon le sens de déplacement de l'appareil. Lorsque l'organe antiblocage rencontre un obstacle sur le plan de guidage de l'appareil, il vient buter contre l'obstacle ce qui force en rotation ledit organe antiblocage roulant ainsi sur l'obstacle, tout en le faisant remonter vers la base de l'appareil avec l'organe en saillie, évitant ainsi que l'organe en saillie se bloque au niveau de l'obstacle.We know, also in this field, the patent application WO201161389 , by the Applicant, which discloses a swimming pool cleaning device comprising a member projecting from its base secured to a rotating anti-blocking member positioned in front of it in the direction of movement of the device. When the anti-blocking member encounters an obstacle on the guiding plane of the device, it abuts against the obstacle which forces said anti-locking member to rotate thus rolling on the obstacle, while causing it to rise towards the base of the obstacle. device with the protruding member, thus preventing the protruding member from being blocked at the level of the obstacle.

Il est également connu dans le même domaine, la demandes de brevet US 5,197,158 , dont l'objet est un appareil de nettoyage de piscine comprenant des flotteurs qui par leur changement de position suite à l'impact de l'appareil avec un obstacle ou suite à la rencontre de l'appareil avec un mur vertical de la piscine, permettent le changement de sens de marche de l'appareil. L'appareil comprend également un organe de soulèvement latéral de l'appareil en saillie de la base de l'appareil qui soulève latéralement l'appareil lorsqu'il change de sens de marche et permet ainsi de lui donner une ligne de trajectoire différente de celle qu'il avait juste avant le changement de sens de marche.It is also known in the same field, the applications of US patent 5,197,158 , the object of which is a swimming pool cleaning device comprising floats which by their change of position following the impact of the device with a obstacle or following the encounter of the device with a vertical wall of the swimming pool, allow the device to change direction. The apparatus also comprises a member for lateral lifting of the apparatus projecting from the base of the apparatus which laterally lifts the apparatus when it changes direction of travel and thus enables it to be given a line of trajectory different from that he had just before the change of direction of travel.

On connait aussi la demande de brevet FR 2 584 442 visant un appareil de nettoyage de piscine comportant également un organe de soulèvement latéral du corps de l'appareil qui, lorsque l'appareil change de sens de marche, soulève latéralement ledit appareil du plan de guidage, de sorte à lui donner une ligne de trajectoire différente de celle qu'il avait juste avant le changement de sens de marche.We also know the demand for patent FR 2 584 442 aimed at a swimming pool cleaning apparatus also comprising a member for lateral lifting of the body of the apparatus which, when the apparatus changes direction of travel, laterally lifts said apparatus from the guide plane, so as to give it a line of trajectory different from the one it had just before the change of direction of travel.

Le document EP1277897A1 divulgue un autre nettoyeur de piscine selon l'état de la technique .The document EP1277897A1 discloses another pool cleaner according to the state of the art.

Il a été constaté que, fréquemment, ces robots présentent des difficultés à franchir des obstacles disposés sur le fond de la piscine, notamment lorsque ces obstacles entrainent la perte de contact d'une des roues appartenant aux moyens d'entrainement et de guidage du robot avec la surface sur laquelle se déplace le robot.It has been observed that, frequently, these robots present difficulties in crossing obstacles arranged on the bottom of the swimming pool, in particular when these obstacles cause the loss of contact of one of the wheels belonging to the means for driving and guiding the robot. with the surface on which the robot is moving.

L'invention a pour but de remédier notamment à cet inconvénient.The object of the invention is to remedy this drawback in particular.

Exposé de l'inventionDisclosure of the invention

L'invention vise sous un premier aspect un appareil de nettoyage de piscine

  • un corps,
  • des moyens d'entrainement et de guidage du corps comprenant au moins deux paires de roues : avant et arrière.
The invention relates in a first aspect to a swimming pool cleaning device
  • a body,
  • means for driving and guiding the body comprising at least two pairs of wheels: front and rear.

Les moyens d'entrainement de l'appareil comportent en outre :

  • une roue intermédiaire articulée autour d'un axe de rotation, disposée entre la roue avant et la roue arrière, au moins d'un des deux côtés de l'appareil, le diamètre et la position de l'axe de rotation de cette roue intermédiaire étant tel que ladite roue ne touche pas le plan de guidage XrYr lorsque le robot est en appui sur celui-ci, ledit plan de guidage XrYr étant défini par les points de contact des roues avant et arrière avec le sol.
The means for driving the apparatus further include:
  • an intermediate wheel articulated around an axis of rotation, arranged between the front wheel and the rear wheel, at least on one of the two sides of the device, the diameter and position of the axis of rotation of this intermediate wheel being such that said wheel does not touch the XrYr guide plane when the robot is resting thereon, said XrYr guide plane being defined by the points of contact of the front and rear wheels with the ground.

On appelle "appareil de nettoyage de piscine" un appareil pour le nettoyage d'une surface immergée, c'est-à-dire typiquement un appareil, mobile au sein ou au fond d'un bassin de piscine, et adapté à effectuer la filtration de débris déposés tant au fond que sur une paroi. Un tel appareil est communément connu sous le nom de robot de nettoyage de piscine, lorsqu'il comporte des moyens de gestion automatisée des déplacements au fond et sur les parois de la piscine pour couvrir toute la surface à nettoyer.The term "swimming pool cleaning apparatus" is used to describe an apparatus for cleaning an immersed surface, that is to say typically an apparatus, mobile within or at the bottom of a swimming pool, and suitable for carrying out filtration. debris deposited both at the bottom and on a wall. Such a device is commonly known under the name of a swimming pool cleaning robot, when it comprises means for automated management of movements at the bottom and on the walls of the swimming pool to cover the entire surface to be cleaned.

L'utilisation d'une roue intermédiaire articulée autour d'un axe de rotation, disposée entre les roues avant et arrière, au moins d'un des deux côtés de l'appareil, et ne touchant pas le plan de guidage XrYr lorsque le robot est en appui sur celui-ci permet que, lorsqu' au moins une des roues avant ou arrière n'est plus en contact avec le sol (la surface sur laquelle se déplace le robot) du fait du franchissement d'un obstacle, la roue intermédiaire vienne en contact avec ledit obstacle et facilite son franchissement. La roue intermédiaire fait partie de moyens d'entrainement, elle est entrainée en rotation autour de son axe de rotation grâce au moteur de l'appareil de nettoyage.The use of an intermediate wheel articulated around an axis of rotation, arranged between the front and rear wheels, at least on one of the two sides of the device, and not touching the guide plane XrYr when the robot is resting on it allows that, when at least one of the front or rear wheels is no longer in contact with the ground (the surface on which the robot is moving) due to the crossing of an obstacle, the wheel intermediary comes into contact with said obstacle and facilitates its crossing. The intermediate wheel is part of the drive means, it is driven in rotation around its axis of rotation by the motor of the cleaning device.

L'effet de l'invention est donc de permettre à un moyen d'entrainement intermédiaire de prendre appui sur et de pousser sur un obstacle qui viendrait dépasser du plan tangent aux roues avant et arrières avec le sol (ce plan étant le plan de contact des roues avec le sol, en l'absence d'obstacle à franchir), pour faciliter son franchissement.The effect of the invention is therefore to allow an intermediate drive means to rest on and push on an obstacle which would protrude from the plane tangent to the front and rear wheels with the ground (this plane being the plane of contact wheels with the ground, in the absence of obstacle to cross), to facilitate crossing.

Un autre avantage d'un tel appareil de nettoyage de piscine est qu'étant donné que la roue intermédiaire n'est en contact avec la surface sur laquelle se déplace le robot que dans des cas où l'appareil rencontre un obstacle sur ladite surface, l'appareil de nettoyage à une consommation en énergie moindre par rapport à un même appareil de nettoyage dont toutes les roues (roue intermédiaire incluse) seraient en contact en permanence avec ladite surface.Another advantage of such a swimming pool cleaning device is that since the intermediate wheel is in contact with the surface on which the robot moves only in cases where the device encounters an obstacle on said surface, the cleaning apparatus with a lower energy consumption compared to the same cleaning apparatus of which all the wheels (intermediate wheel included) would be in permanent contact with said surface.

Dans un mode de réalisation particulier, l'axe de rotation autour duquel est articulée la roue intermédiaire, est parallèle à l'axe transversal Yr, qui correspond à l'axe d'entrainement des roues avant et arrière. Dans un autre mode de réalisation particulier, l'axe de rotation autour duquel est articulée la roue intermédiaire n'est pas parallèle à l'axe transversal Yr.In a particular embodiment, the axis of rotation around which the intermediate wheel is articulated is parallel to the transverse axis Yr, which corresponds to the drive axis of the front and rear wheels. In another particular embodiment, the axis of rotation around which the intermediate wheel is articulated is not parallel to the transverse axis Yr.

Dans un mode de réalisation particulier, l'axe de rotation de la roue intermédiaire est situé dans le plan défini par les axes de rotation des roues avant et arrière.In a particular embodiment, the axis of rotation of the intermediate wheel is located in the plane defined by the axes of rotation of the front and rear wheels.

Dans un mode de réalisation particulier, la roue intermédiaire est située longitudinalement pratiquement à mi distance entre les roues avant et arrière.In a particular embodiment, the intermediate wheel is located longitudinally practically halfway between the front and rear wheels.

Dans un mode de réalisation particulier, la roue intermédiaire comporte en sa circonférence une zone de friction, de forme sensiblement cylindrique, dotée d'un état de surface antidérapant.In a particular embodiment, the intermediate wheel has a friction zone in its circumference, of substantially cylindrical shape, provided with a non-slip surface condition.

Dans un mode de réalisation particulier, la roue intermédiaire est entrainée en rotation grâce à une zone interne engrenée de ladite roue, de diamètre inférieur à celui de la zone de friction, cette zone engrenée venant coopérer avec un engrenage, lui même entrainé par la roue arrière ou la roue avant.In a particular embodiment, the intermediate wheel is driven in rotation thanks to an internal meshed zone of said wheel, of diameter smaller than that of the friction zone, this meshed zone coming to cooperate with a gear, itself driven by the wheel. rear or front wheel.

Dans un mode de réalisation particulier, la zone engrenée de la roue intermédiaire vient coopérer avec deux engrenages, entrainés par les roues arrière et avant.In a particular embodiment, the meshed zone of the intermediate wheel cooperates with two gears, driven by the rear and front wheels.

Dans un mode de réalisation particulier, la roue intermédiaire est entrainée par le jeu d'engrenages à une vitesse différente des roues avant et arrière.In a particular embodiment, the intermediate wheel is driven by the set of gears at a speed different from the front and rear wheels.

Dans un mode de réalisation particulier, la roue intermédiaire vient tourner dans le même sens que les roues avant et arrière, cette roue intermédiaire présentant une vitesse de rotation telle que la vitesse tangentielle de la zone de friction soit sensiblement égale à celle des roues avant et arrière.In a particular embodiment, the intermediate wheel rotates in the same direction as the front and rear wheels, this intermediate wheel having a speed of rotation such that the tangential speed of the friction zone is substantially equal to that of the front wheels and back.

Dans un mode de réalisation particulier, la roue intermédiaire vient tourner dans le même sens que les roues avant et arrière, cette roue intermédiaire présentant une vitesse de rotation telle que la vitesse tangentielle de la zone de friction soit plus lente que celle des roues avant et arrière. Une telle vitesse plus lente permet de réduire les éventuels glissements de la roue intermédiaire sur l'obstacle à franchir.In a particular embodiment, the intermediate wheel turns in the same direction as the front and rear wheels, this intermediate wheel having a speed of rotation such that the tangential speed of the friction zone is slower than that of the front wheels and back. Such a slower speed makes it possible to reduce any slippage of the intermediate wheel on the obstacle to be crossed.

Dans un mode de réalisation particulier, les moyens d'entrainement de l'appareil de nettoyage comportent une roue intermédiaire de chaque côté du corps.In a particular embodiment, the drive means of the cleaning apparatus comprise an intermediate wheel on each side of the body.

Dans un mode de réalisation particulier, la zone de friction comporte au moins une excroissance formant ergot, adaptée à prendre appui sur un obstacle situé au fond de la piscine pour faciliter son franchissement par ledit appareil de nettoyage.In a particular embodiment, the friction zone comprises at least one protuberance forming a lug, adapted to bear on an obstacle located at the bottom of the swimming pool to facilitate its crossing by said cleaning device.

Dans un mode de réalisation particulier, la roue intermédiaire est articulée autour d'un axe de rotation excentrique. Dans un tel mode de réalisation, la roue intermédiaire ne touche toujours pas le plan de guidage XrYr lorsque le robot est en appui sur celui-ci.In a particular embodiment, the intermediate wheel is articulated around an eccentric axis of rotation. In such an embodiment, the intermediate wheel still does not touch the guide plane XrYr when the robot is resting on it.

Dans un mode de réalisation particulier, les moyens d'entrainement de l'appareil de nettoyage de piscine comportent une roue intermédiaire de chaque côté du corps, ces roues intermédiaires étant de diamètre et / ou de vitesse de rotation différentes.In a particular embodiment, the drive means of the swimming pool cleaning apparatus comprise an intermediate wheel on each side of the body, these intermediate wheels being of different diameter and / or speed of rotation.

Description détaillée d'un mode de réalisation de l'inventionDetailed description of an embodiment of the invention

L'invention trouve sa place au sein d'un environnement technique de piscine, par exemple une piscine enterrée de type familial.The invention finds its place within a technical swimming pool environment, for example an in-ground swimming pool of the family type.

Un système de nettoyage de surface immergée comporte, dans le présent exemple de réalisation, un appareil de nettoyage 10, appelée plus loin robot de nettoyage de piscine, et une unité d'alimentation et de commande dudit robot de nettoyage de piscine (non illustrée sur les figures). Dans une variante, cette unité d'alimentation et de commande peut être intégrée à l'appareil de nettoyage.A submerged surface cleaning system comprises, in the present example embodiment, a cleaning apparatus 10, referred to below as a swimming pool cleaning robot, and a power supply and control unit for said swimming pool cleaning robot (not illustrated on the figures). In a variant, this supply and control unit can be integrated into the cleaning device.

L'appareil de nettoyage 10 est représenté selon un mode de réalisation donné ici à titre d'exemple, en figures 1 et 2 .The cleaning apparatus 10 is shown according to an embodiment given here by way of example, in figures 1 and 2 .

Sur ces figures, le type d'appareil est ici à éjection d'eau dirigée vers l'arrière de l'appareil relativement au plan de roulement de l'appareil. Dans un autre mode de réalisation, l'appareil est à éjection d'eau dirigée vers le haut de l'appareil, relativement au plan de roulement du robot.In these figures, the type of device is here with water ejection directed towards the rear of the device relative to the running surface of the device. In another embodiment, the apparatus has water ejection directed towards the top of the apparatus, relative to the running surface of the robot.

L'appareil de nettoyage de piscine comprend un corps 11 et des moyens d'entraînement et de guidage 12 du corps 11 sur une surface immergée. Dans le présent exemple, ces moyens d'entrainement et de guidage 12 sont constitués de roues avant 32 et arrières 33, disposées de façon latérale au corps (voir figure 1).The pool cleaning apparatus comprises a body 11 and driving and guiding means 12 of the body 11 on a submerged surface. In the present example, these drive and guide means 12 consist of front 32 and rear 33 wheels, arranged sideways to the body (see figure 1 ).

Ces moyens d'entraînement et du guidage définissent un plan de guidage sur une surface immergée par leurs points de contact avec ladite surface immergée. Ledit plan de guidage est généralement sensiblement tangent à la surface immergée au point auquel se trouve l'appareil. Ledit plan de guidage est par exemple sensiblement horizontal lorsque l'appareil se déplace sur une surface immergée de fond de piscine. Un tel plan de guidage est défini sur les figures de la présente demande selon les axes Xr et Yr perpendiculaires. Il est nommé plan de guidage XrYr.These drive and guide means define a guide plane on a submerged surface by their points of contact with said submerged surface. Said guide plane is generally substantially tangent to the submerged surface at the point at which the device is located. Said guide plane is for example substantially horizontal when the device moves on a submerged surface of the pool bottom. Such a guide plane is defined in the figures of the present application along the perpendicular axes Xr and Yr. It is called the XrYr guidance plane.

Dans tout le texte les notions « haut » et « bas » sont définies le long d'une droite, perpendiculaire audit plan de guidage, un élément « bas » étant plus proche du plan de guidage qu'un élément haut.Throughout the text, the concepts “top” and “bottom” are defined along a straight line, perpendicular to said guide plane, a “bottom” element being closer to the guide plane than a top element.

L'appareil de nettoyage de piscine comprend en outre un moteur entraînant lesdits moyens d'entraînement et de guidage, ledit moteur étant, dans le présent exemple, alimenté en énergie par l'unité de commande et de contrôle via un câble souple étanche.The swimming pool cleaning apparatus further comprises a motor driving said drive and guide means, said motor being, in the present example, supplied with energy by the command and control unit via a waterproof flexible cable.

L'appareil de nettoyage de piscine présente au moins une entrée de liquide 13 et une sortie de liquide 14. L'entrée de liquide 13 est située à la base du corps (en d'autres termes sous celui-ci), c'est-à-dire immédiatement en regard d'une surface immergée sur laquelle se déplace l'appareil afin de pouvoir aspirer les débris accumulés sur ladite surface immergée.The swimming pool cleaning apparatus has at least one liquid inlet 13 and one liquid outlet 14. The liquid inlet 13 is located at the base of the body (in other words under it), that is, that is to say immediately opposite a submerged surface on which the device moves in order to be able to suck up the debris accumulated on said submerged surface.

La sortie de liquide 14 se situe ici sur le capot, à l'arrière de l'appareil. Dans le présent exemple, la sortie de liquide se fait dans une direction orientée vers l'arrière de l'appareil. Cette disposition n'est cependant pas limitative, et une sortie d'eau sensiblement perpendiculaire au plan de guidage, c'est-à-dire verticalement si l'appareil de nettoyage repose sur le fond de la piscine, est également envisageable.The liquid outlet 14 is located here on the cover, at the rear of the device. In the present example, the liquid outlet is in a direction facing the rear of the apparatus. This arrangement is not, however, limiting, and a water outlet substantially perpendicular to the guide plane, that is to say vertically if the cleaning device rests on the bottom of the swimming pool, is also possible.

L'appareil comprend un circuit hydraulique reliant l'entrée de liquide 13 à la sortie de liquide 14. Le circuit hydraulique est adapté pour pouvoir assurer une circulation de liquide depuis l'entrée de liquide 13 vers la sortie de liquide 14. L'appareil comprend à cet effet une pompe de circulation comprenant un moteur électrique et une hélice, ledit moteur électrique entraînant l'hélice en rotation, ladite hélice étant disposée dans le circuit hydraulique.The apparatus comprises a hydraulic circuit connecting the liquid inlet 13 to the liquid outlet 14. The hydraulic circuit is adapted to be able to ensure circulation of liquid from the liquid inlet 13 to the liquid outlet 14. The apparatus comprises for this purpose a circulation pump comprising an electric motor and a propeller, said electric motor driving the propeller in rotation, said propeller being arranged in the hydraulic circuit.

L'appareil comprend une chambre de filtration 17 interposée, sur le circuit hydraulique, entre l'entrée de liquide 13 et la sortie de liquide 14. La chambre de filtration est en particulier alimentée en liquide via au moins un canal amont reliant l'entrée de liquide 13 à la chambre de filtration 17.The apparatus comprises a filtration chamber 17 interposed, on the hydraulic circuit, between the liquid inlet 13 and the liquid outlet 14. The filtration chamber is in particular supplied with liquid via at least one upstream channel connecting the inlet. of liquid 13 to the filtration chamber 17.

La chambre de filtration 17 comprend un panier de filtration. Ce panier de filtration est avantageusement mais non nécessairement amovible.The filtration chamber 17 includes a filtration basket. This filtration basket is advantageously but not necessarily removable.

Comme on le voit sur les figures 3 à 7 , dans le présent exemple de réalisation, les moyens d'entrainement comportent par ailleurs une roue intermédiaire 31, disposée entre la roue avant 32 et la roue arrière 33, au moins d'un des deux côtés de l'appareil.As seen on figures 3 to 7 , in this exemplary embodiment, the drive means furthermore comprise an intermediate wheel 31, disposed between the front wheel 32 and the rear wheel 33, at least on one of the two sides of the device.

Cette roue intermédiaire 31 est ici articulée autour d'un axe 34 parallèle à l'axe transversal Yr, qui correspond à l'axe d'entrainement des roues avant 32 et arrière 33. Dans une variante de réalisation, cette roue intermédiaire 31 est articulée autour d'un axe non parallèle à l'axe transversal. Dans le présent exemple, cet axe 34 est situé dans le plan défini par les axes des roues avant et arrière, sans que cela soit une condition nécessaire au fonctionnement du dispositif selon l'invention.This intermediate wheel 31 is here articulated around an axis 34 parallel to the transverse axis Yr, which corresponds to the drive axis of the front 32 and rear 33 wheels. In an alternative embodiment, this intermediate wheel 31 is articulated. around an axis not parallel to the transverse axis. In the present example, this axis 34 is located in the plane defined by the axes of the front and rear wheels, without this being a necessary condition for the operation of the device according to the invention.

Ainsi qu'il apparaît notamment sur la figure 3, le diamètre et la position de l'axe de rotation 34 de cette roue intermédiaire 31 est tel que ladite roue ne touche pas le plan de guidage XrYr lorsque le robot est en appui sur celui-ci. Le décalage vertical entre ledit plan de guidage XrYr et le bas de la roue intermédiaire 31 est ici d'environ 2 centimètres. Cette valeur est ici donnée à titre purement illustratif, et d'autres valeurs supérieures ou inférieures peuvent être envisagées.As it appears in particular on the figure 3 , the diameter and the position of the axis of rotation 34 of this intermediate wheel 31 is such that said wheel does not touch the guide plane XrYr when the robot is resting on it. The vertical offset between said guide plane XrYr and the bottom of the intermediate wheel 31 is here about 2 centimeters. This value is given here for illustrative purposes only, and other higher or lower values can be considered.

Dans le présent exemple de réalisation, la roue intermédiaire 31 est située longitudinalement pratiquement à mi distance entre les roues avant 32 et arrière 33.In the present exemplary embodiment, the intermediate wheel 31 is situated longitudinally practically halfway between the front 32 and rear 33 wheels.

Son diamètre est ici légèrement inférieur à celui de la roue avant 32, lequel est également inférieur à celui de la roue arrière 33.Its diameter is here slightly less than that of the front wheel 32, which is also less than that of the rear wheel 33.

La roue intermédiaire 31 comporte en sa circonférence une zone de friction 35, de forme sensiblement cylindrique, dotée d'un état de surface antidérapant. La largeur de cette zone de friction 35 est ici d'environ un à deux centimètres. Cette largeur, ainsi que la matière formant la zone d'adhérence de la roue, dépendent du type de sol sur lequel le robot doit évoluer.The intermediate wheel 31 comprises in its circumference a friction zone 35, of substantially cylindrical shape, provided with a non-slip surface condition. The width of this friction zone 35 is here about one to two centimeters. This width, as well as the material forming the grip zone of the wheel, depend on the type of ground on which the robot must operate.

La roue intermédiaire 31 est ici entrainée en rotation grâce à une zone interne engrenée 36, de diamètre inférieur à celui de la zone de friction. Cette zone engrenée 36 vient coopérer avec un engrenage 37, lui même entrainé par la roue arrière 33. De la même manière, la zone engrenée 36 vient coopérer avec un second engrenage 38, lui même entrainé par la roue avant 32. La roue intermédiaire 31 est donc ici indirectement entrainée par le moteur d'entrainement des roues.The intermediate wheel 31 is here driven in rotation by virtue of a meshed internal zone 36, of diameter smaller than that of the friction zone. This meshed zone 36 cooperates with a gear 37, itself driven by the rear wheel 33. Likewise, the meshed zone 36 cooperates with a second gear 38, itself driven by the front wheel 32. The intermediate wheel 31 is therefore here indirectly driven by the wheel drive motor.

Les géométries précises et matériaux de ces engrenages 37, 38 peuvent être facilement déterminé par l'homme du métier, selon les caractéristiques particulières du robot de nettoyage considéré.The precise geometries and materials of these gears 37, 38 can be easily determined by those skilled in the art, depending on the particular characteristics of the cleaning robot considered.

On comprend que, par la disposition du jeu d'engrenages, la roue intermédiaire 31 vient tourner dans le même sens que les roues avant 32 et arrière 33. Dans le présent exemple de réalisation, cette roue intermédiaire 31 présente une vitesse de rotation telle que la vitesse tangentielle de la zone de friction 35 soit sensiblement égale à celle des roues avant 32 et arrière 33. Elle peut également présenter une vitesse de rotation telle que la vitesse tangentielle de la zone de friction 35 soit plus lente que celle des roues avant 32 et arrière 33.It will be understood that, by the arrangement of the set of gears, the intermediate wheel 31 rotates in the same direction as the front 32 and rear 33 wheels. In the present exemplary embodiment, this intermediate wheel 31 has a speed of rotation such that the tangential speed of the friction zone 35 is substantially equal to that of the front 32 and rear 33 wheels. It can also have a speed of rotation such that the tangential speed of the friction zone 35 is slower than that of the front 32 and rear 33 wheels.

Mode de fonctionnementOperating mode

Lorsque l'appareil de nettoyage 10 vient franchir un obstacle, il arrive qu'une des roues avant 32 ou arrière 33 ne soit plus en contact avec la surface de guidage. Dans ce cas, un robot selon l'art antérieur a des difficultés à se mouvoir.When the cleaning device 10 crosses an obstacle, it happens that one of the front 32 or rear 33 wheels is no longer in contact with the guide surface. In this case, a robot according to the prior art has difficulty moving.

Au contraire, dans le cas décrit plus haut, lorsque la roue avant 32 (ou arrière 33) n'est plus en contact avec la surface de guidage du fait de la présence d'un obstacle qui a fait se lever la partie avant de l'appareil de nettoyage 10, la roue intermédiaire 31 vient prendre appui sur l'obstacle, roule sur ce dernier du fait de son entrainement par le moteur de l'appareil 10, et permet audit appareil de nettoyage un franchissement aisé de cet obstacle.On the contrary, in the case described above, when the front wheel 32 (or rear 33) is no longer in contact with the guide surface due to the presence of an obstacle which made the front part of the wheel rise. 'cleaning device 10, the intermediate wheel 31 comes to bear on the obstacle, rolls on the latter due to its drive by the motor of the device 10, and allows said cleaning device an easy crossing of this obstacle.

VariantesVariants

Dans une variante de réalisation, les moyens d'entrainement de l'appareil de nettoyage comportent une roue intermédiaire 31 de chaque côté du corps 11.In an alternative embodiment, the driving means of the cleaning apparatus comprise an intermediate wheel 31 on each side of the body 11.

Dans une autre variante de réalisation, la zone de friction 35 comporte au moins une excroissance 39 formant ergot, adaptée à prendre appui sur un obstacle situé au fond de la piscine pour faciliter son franchissement par le robot 10. Elle peut alternativement comporter un plus grand nombre d'excroissances, par exemple trois excroissances réparties angulairement de façon régulière.In another variant embodiment, the friction zone 35 comprises at least one protuberance 39 forming a lug, adapted to bear on an obstacle located at the bottom of the swimming pool to facilitate its crossing by the robot 10. It can alternatively include a larger one. number of protuberances, for example three protuberances distributed angularly in a regular manner.

Dans encore une autre variante de réalisation, la roue intermédiaire 31 est articulée autour d'un axe 34 excentrique. De la sorte, la distance entre le plan de guidage et la roue intermédiaire n'est pas fixe, mais varie au cours de la rotation de cette roue 31.In yet another variant embodiment, the intermediate wheel 31 is articulated about an eccentric axis 34. In this way, the distance between the guide plane and the intermediate wheel is not fixed, but varies during the rotation of this wheel 31.

Dans encore une autre variante de réalisation, la roue intermédiaire 31 est entrainée par le jeu d'engrenages à une vitesse différente des roues avant et arrière, par exemple telle que la vitesse tangentielle de la zone de friction soit deux fois plus rapide que la vitesse tangentielle des roues avant 32 et arrière 33 en leur point de contact avec le plan de guidage XrYr.In yet another variant embodiment, the intermediate wheel 31 is driven by the set of gears at a speed different from the front and rear wheels, for example such that the tangential speed of the friction zone is twice as fast as the speed. tangential to the front 32 and rear 33 wheels at their point of contact with the guide plane XrYr.

Dans une variante de réalisation, les moyens d'entrainement de l'appareil de nettoyage 10 comportent une roue intermédiaire 31 de chaque côté du corps 11, ces roues intermédiaires 31 étant de diamètre et / ou de vitesse de rotation différentes.In an alternative embodiment, the drive means of the cleaning apparatus 10 comprise an intermediate wheel 31 on each side of the body 11, these intermediate wheels 31 being of different diameter and / or speed of rotation.
