APPAREIL NETTOYEUR DE PISCINE À DISPOSITIF DE FRANCHISSEMENT  SWIMMING POOL CLEANER APPARATUS WITH CROSSING DEVICE
D'OBSTACLE  OBSTACLE
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 swimming pool equipment. It relates more particularly to an autonomous pool cleaner robot type.
Préambule et art antérieur Preamble 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 a device for cleaning a surface immersed in a liquid, such as a surface formed by the walls of a pool, in particular a swimming pool. These include a mobile pool cleaning robot. Such a cleaning robot carries out said cleaning by traversing the bottom and walls of the pool of the pool, brushing these walls, and sucking the debris to a filter. Debris means all the particles present in the basin, such as pieces of leaves, microalgae, etc., these debris being normally deposited at the bottom of the basin or glued on the side walls thereof.
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 powered by an electrical cable connecting the robot to an outdoor control unit and power supply.
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.  For example, there are known in this field, patents FR 2 925 557 and 2 925 551, of the applicant, which are directed to a submerged surface cleaner device with removable filter device. Such devices comprise a body, drive members of said body on the immersed surface, a filtration chamber formed within the body and comprising a liquid inlet, a liquid outlet, a hydraulic circuit for liquid circulation between the input and output through a filter device.
On connaît, également dans ce domaine, la demande de brevet WO201 161389, 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.  Also known in this field, the patent application WO201 161389, of the applicant, which discloses a swimming pool cleaning device comprising a member projecting from its base secured to a rotational anti-lock member positioned in front of it in the direction of travel. of the device. When the anti-lock member encounters an obstacle on the guide plane of the apparatus, it abuts against the obstacle which forces in rotation said anti-lock member thus rolling over the obstacle, while causing it to rise towards the base of the device with the protruding member, thereby avoiding the protruding member is blocked at 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, patent application US 5,197,158, whose object is a swimming pool cleaning device comprising floats which by their position change following the impact of the device with a obstacle or following the meeting of the device with a vertical wall of the pool, allow the change of direction of the device. The apparatus also comprises a lateral lifting member of the apparatus projecting from the base of the apparatus which raises the apparatus laterally when it changes direction of travel and thus makes it possible to give it a line of trajectory different from that he had just before the change of direction.
On connaît 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.  Also known is the patent application FR 2,584,442 for a swimming pool cleaning apparatus also comprising a lateral lifting member of the body of the apparatus which, when the apparatus changes direction of travel, raises laterally said apparatus of the plane of guidance, so as to give it a different trajectory line than it had just before the change of direction.
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 entraînent la perte de contact d'une des roues appartenant aux moyens d'entraînement et de guidage du robot avec la surface sur laquelle se déplace le robot.  It has been found that, frequently, these robots have difficulty crossing obstacles arranged on the bottom of the pool, especially when these obstacles cause the loss of contact with one of the wheels belonging to the drive and guiding means of the robot. with the surface on which the robot moves.
L'invention a pour but de remédier notamment à cet inconvénient.  The object of the invention is to overcome this drawback.
Exposé de l'invention Presentation of the invention
L'invention vise sous un premier aspect un appareil de nettoyage de piscine The invention aims in a first aspect a swimming pool cleaning apparatus
- un corps, - a body,
- des moyens d'entraînement et de guidage du corps comprenant au moins deux paires de roues : avant et arrière.  driving and guiding means of the body comprising at least two pairs of wheels: front and rear.
Les moyens d'entraînement de l'appareil comportent en outre :  The drive means of the apparatus further comprise:
- 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.  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 apparatus, the diameter and the position of the axis of rotation of this wheel intermediate being such that said wheel does not touch the XrYr guide plane when the robot is resting on it, said XrYr guide plane being defined by the contact points 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. 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 entraînée en rotation autour de son axe de rotation grâce au moteur de l'appareil de nettoyage. The term "pool cleaning apparatus" is intended to mean an apparatus for cleaning a submerged surface, that is to say typically a device, mobile within or at the bottom of a swimming pool, and adapted to carry out the filtration. debris deposited both at the bottom and on a wall. Such an apparatus is commonly known as a pool cleaning robot, when it comprises means of automated management of movements at the bottom and on the walls of the pool to cover the entire surface to be cleaned. The use of an intermediate wheel articulated about an axis of rotation, disposed between the front and rear wheels, at least on one of the two sides of the device, and not touching the XrYr guide plane when the robot is supported 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 moves) because of the crossing of an obstacle, the wheel intermediate comes into contact with said obstacle and facilitates its crossing. The intermediate wheel is part of driving means, it is rotated about its axis of rotation by the engine 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 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 bear on and push an obstacle that would exceed the plane tangent to the front and rear wheels with the ground (this plane being the contact plane of the wheels with the ground, in the absence of obstacle to cross), to facilitate its 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 pool cleaning apparatus is that since the intermediate wheel is in contact with the surface on which the robot is moving only in cases where the apparatus encounters an obstacle on said surface, the cleaning apparatus has a lower energy consumption compared to the same cleaning apparatus with all the wheels (intermediate wheel included) in permanent contact with said surface.
L'invention concerne également un appareil nettoyeur de surface immergée caractérisé en combinaison par tout ou partie des caractéristiques mentionnées ci- dessus ou ci-après.  The invention also relates to an immersed surface cleaning apparatus characterized in combination by all or some of the characteristics mentioned above or below.
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 about 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 about 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 substantially midway 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. Dans un mode de réalisation particulier, la roue intermédiaire est entraînée 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 entraîné par la roue arrière ou la roue avant. In a particular embodiment, the intermediate wheel has in its circumference a friction zone, of substantially cylindrical shape, with a non-slip surface state. In a particular embodiment, the intermediate wheel is rotated by means of an inner zone of said wheel with a diameter smaller than that of the friction zone, this intermeshing zone cooperating with a gear, itself driven by the wheel. rear or the front wheel.
Dans un mode de réalisation particulier, la zone engrenée de la roue intermédiaire vient coopérer avec deux engrenages, entraînés par les roues arrière et avant.  In a particular embodiment, the intermeshing 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 entraînée 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 different speed of 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 rotational speed 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 rotates in the same direction as the front and rear wheels, this intermediate wheel having a rotational speed 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'entraînement 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 pin, adapted to bear on an obstacle located at the bottom of the 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 does not yet touch the XrYr guide plane when the robot is resting on it.
Dans un mode de réalisation particulier, les moyens d'entraînement 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 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'invention Detailed 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 in a swimming pool technical environment, for example a family-type buried pool.
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 embodiment, a cleaning apparatus 10, hereinafter referred to as a pool cleaning robot, and a feeding and control unit of said pool cleaning robot (not shown on the figures). Alternatively, this power supply and control unit can be integrated into the cleaning apparatus.
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 FIGS. 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 water ejection directed towards the rear of the device relative to the running surface of the device. In another embodiment, the apparatus is ejection of water directed towards the top of the apparatus, relative to the rolling plane of the robot.
L'appareil de nettoyage de piscine comprend un corps 11 et des moyens d'entraînement et de guidage 12 du corps 1 1 sur une surface immergée. Dans le présent exemple, ces moyens d'entraînement 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 drive and guide means 12 of the body 1 1 on a submerged surface. In the present example, these drive and guide means 12 consist of front wheels 32 and rear 33, disposed laterally 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 surface immersed by their points of contact with said immersed surface. Said guide plane is generally substantially tangential to the immersed surface at point where 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 XrYr guidance plan.
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 notions "up" and "down" are defined along a straight line, perpendicular to said guide plane, a "low" element being closer to the guide plane than a high 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 pool cleaning apparatus further comprises a motor driving said driving and guiding means, said motor being, in the present example, powered by the control and control unit via a sealed 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 pool cleaner 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, below it), it is ie immediately facing a submerged surface on which the device moves in order to suck debris accumulated on said immersed 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 hood at the rear of the apparatus. In the present example, the liquid outlet is in a direction towards the rear of the apparatus. This provision 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 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 a 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 rotating propeller, said propeller being disposed 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 comprises a filter basket. This filter 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'entraînement 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 can be seen in FIGS. 3 to 7, in the present exemplary embodiment, the drive means also comprise an intermediate wheel 31, disposed between the front wheel 32 and the rear wheel 33, at least 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'entraînement 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 about an axis 34 parallel to the transverse axis Yr, which corresponds to the drive axis of the front wheels 32 and rear 33. In an alternative embodiment, the 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 in Figure 3, the diameter and the position of the axis of rotation 34 of the intermediate wheel 31 is such that said wheel does not touch the XrYr guide plane when the robot is supported on it this. The vertical offset between said XrYr guide plane and the bottom of the intermediate wheel 31 is here about 2 centimeters. This value is here given for purely illustrative purposes, and other higher or lower values can be envisaged.
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 embodiment, the intermediate wheel 31 is located longitudinally substantially midway between the front wheels 32 and rear 33.
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 here is slightly less than that of the front wheel 32, which is also smaller 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, with a non-slip surface state. The width of this friction zone 35 is here about one to two centimeters. This width, as well as the material forming the adhesion zone of the wheel, depends on the type of soil on which the robot must evolve.
La roue intermédiaire 31 est ici entraînée 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 entraîné par la roue arrière 33. De la même manière, la zone engrenée 36 vient coopérer avec un second engrenage 38, lui même entraîné par la roue avant 32. La roue intermédiaire 31 est donc ici indirectement entraînée par le moteur d'entraînement des roues.  The intermediate wheel 31 is here rotated by an inner geared zone 36, of smaller diameter than that of the friction zone. This intermeshed zone 36 cooperates with a gear 37, itself driven by the rear wheel 33. In the same way, the intermeshed zone 36 cooperates with a second gear 38, itself driven by the front wheel 32. The intermediate wheel 31 is here indirectly driven by the drive motor of the wheels.
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, according to 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 is understood that, by the arrangement of the gear set, the intermediate wheel 31 rotates in the same direction as the front wheels 32 and rear 33. In this embodiment, this intermediate wheel 31 has a rotation speed such that the tangential velocity of the friction zone 35 is substantially equal to that of the front wheels 32 and rear 33. It may also have a rotational speed such that the tangential speed of the friction zone 35 is slower than that of the front wheels 32 and rear 33.
Mode de fonctionnement Operating 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 apparatus 10 comes over an obstacle, it happens that one of the front wheels 32 or rear 33 is no longer in contact with the guide surface. In this case, a robot according to the prior art has difficulty in 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 entraînement 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 caused the front part of the wheel to rise. 10, the intermediate wheel 31 is supported on the obstacle, rolls on the latter because of its drive by the engine of the device 10, and allows said cleaning device easy crossing this obstacle.
Variantes variants
Dans une variante de réalisation, les moyens d'entraînement de l'appareil de nettoyage comportent une roue intermédiaire 31 de chaque côté du corps 1 1 .  In an alternative embodiment, the drive means of the cleaning apparatus comprise an intermediate wheel 31 on each side of the body January 1.
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 projection 39 forming a pin, adapted to bear on an obstacle located at the bottom of the pool to facilitate its crossing by the robot 10. It may alternatively comprise a larger number of excrescences, for example three excrescences angularly distributed regularly.
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 embodiment, the intermediate wheel 31 is articulated about an axis 34 eccentric. 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 entraînée 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 embodiment, the intermediate wheel 31 is driven by the set of gears at a different speed of the front and rear wheels, for example such that the tangential speed of the friction zone is twice as fast as the speed tangentially of the front wheels 32 and rear 33 at their point of contact with the guide plane XrYr.
Dans une variante de réalisation, les moyens d'entraînement de l'appareil de nettoyage 10 comportent une roue intermédiaire 31 de chaque côté du corps 1 1 , 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 January 1, these intermediate wheels 31 being of different diameter and / or speed of rotation.
