Definitions
- the present invention belongs to the field of swimming pool maintenance devices, in particular swimming pool cleaning robots, and relates more particularly to an autonomous vacuum cleaning robot with alternating suction for cleaning swimming pools.
- swimming pool robots the main function of which is the suction of debris.
- electric robots There are different types of pool robots among which are electric robots.
- European patent EP3283711 B1 in the name of the applicant, discloses a swimming pool cleaning robot comprising an electro-hydraulic power unit / water jet pump, and a debris collection body which comprises a battery for supplying said group, the group and the battery being contained in a rotating and waterproof turret, outside the robot body.
- the robot advantageously comprises an automatic direction reversal device comprising a pallet integral with the turret.
- This bidirectional robot moves alternately in two substantially opposite directions, propelled by the reaction of a water jet issuing from a rotating nozzle, integral with the turret, adapted to take two opposite angular positions.
- the suction takes place independently of the direction of movement of the robot.
- Most robots have a main suction port through which water enters the robot's debris collection body regardless of the movement of the robot.
- Some robots are equipped with several suction ports, for example two mouths, one of which is located near the front side of the robot and the other at the rear of the robot, for repeated passage over the suction area. debris, in other words for successive aspirations, in order to refine cleaning and collection of debris. Nevertheless, the suction power obtained with several mouths remains equivalent to that which would be obtained with a single mouth of section equal to the sum of the sections of said mouths. In addition, when the suction power is not enough to "lift" the heaviest debris as soon as it passes through the first suction mouth, the passage of the second mouth remains just as futile, if not barely more effective.
- the two suction ports do not have the same utility depending on the direction of movement of the robot.
- the suction mouth which is found at the front following the direction of movement of the robot sucks up a major part of the debris and the other mouth, at the rear, only sucks up a few debris which have remained at the bottom.

- Pool robots are equipped with one or more suction pumps and can have one or two suction ports.
- a single mouth generally located in the axis of the robot, does not effectively capture debris near peripheral walls, for example.
- the solution which consists in creating a mouth at each end of the robot would solve this problem, but the simultaneous operation of these two mouths results in a lower suction flow rate at each mouth, and therefore in a loss of efficiency. Maintaining the efficiency of two mouths operated simultaneously would imply a doubling of the suction power of the pump, which would increase costs, double energy consumption, and penalize the autonomy of a battery-powered robot.
- the proposed solution makes it possible to solve this problem without increasing power and without losing efficiency by producing a robot with two end openings in alternating operation so as to have on the active mouth all of the flow drawn by the pump.
- the main object of the present invention is to overcome the limitations of the prior art by proposing a swimming pool robot with alternating suction, said suction being operated by a single mouth at a time depending on the direction of movement of said robot, thus improving the suction efficiency and / or reducing the energy consumption of the robot.
- the present invention relates to a swimming pool cleaning robot comprising a body for collecting debris, a propulsion and suction system capable of moving the robot alternately in two substantially opposite directions, and a supply device, such as than a battery pack.

- the propulsion and suction system and the feed device are contained in a rotating and sealed turret, external to the body of the robot, and each direction of movement of the robot is determined by an automatic orientation of the turret.
- the propulsion and suction system comprises two motorized propellers, each of said propellers ensuring the propulsion of the robot in one of the directions of movement and the suction in one of the filtering compartments.
- the robot comprises a pivoting suction mouth integral with the turret, said mouth allowing the passage of water into one compartment and blocking the passage of water into the other compartment, so as to concentrate the total suction. of the robot in one compartment or the other depending on the direction of movement of the robot.

- the pivoting suction mouth is in the form of a hollow cylinder with a circular base, the lateral opening being made at the level of a diameter of said cylinder and the upper opening being axial and contiguous with said lateral opening.
- the pivoting suction mouth is arranged above the partition so as to be flush with an upper edge of said partition.
- the rotating suction mouth can be screwed onto the turret.
- the propulsion and suction system is an electrohydraulic water jet powertrain / pump.
- robot or the expression “swimming pool robot” designates indifferently and by extension an autonomous robot for cleaning swimming pools.
- the figures 1 and 2 show a robot 100 according to the invention mainly comprising a body 10, formed by the assembly of an upper shell 11 and a lower shell 12, a sealed turret 20, containing an electrohydraulic powertrain / pump and its electric battery d 'supply not shown, wheels 30 and water inlets 40a and 40b provided in the bottom of the body 10.
- Body 10 can be of any shape and size to accommodate different sizes of basins, preferably a substantially compact shape and small dimensions for convenience and unobtrusiveness.
- the body 10 consists of two interlocking parts, the upper shell 11 and the lower shell 12, thus facilitating disassembly of the body 10 for access to the interior volume of said body.
- the interior volume of the body 10, visible on the figure 3 contains for its part a debris collection device in the form of a filter 13 placed above a tank materialized by a lower part of said body, for example the lower shell 12.
- the turret 20 surmounts the body 10 and essentially contains the powertrain / electro-hydraulic water jet pump and the electric supply battery, shown in broken lines on the figure. figure 3 .
- the turret 20 is mounted on the body 10 by a rotary connection, produced here by an annular flange of the body around a receiving hole of an annular base of the turret, and is oriented according to the direction of movement of the robot 100 in accordance with the principle described in the patent EP3283711B1 .
- turret is used here in its general sense of a rotary device placed on a vehicle to orient an organ and possibly protect it.
- the power train / pump comprises an electric motor, reduction gears and a turbine whose function is to suck the water, which enters through the water inlets 40a and 40b and passes through the filter 13, and to discharge it through an ejection nozzle 21 which emerges from the turret 20 to propel the robot 100, the direction of the discharge being substantially parallel to the bottom of the swimming pool so as to promote propulsion.

Description
La présente invention appartient au domaine des dispositifs d'entretien de piscines, notamment des robots de nettoyage de piscines, et concerne plus particulièrement un robot aspirateur autonome à aspiration alternée pour le nettoyage de piscines.The present invention belongs to the field of swimming pool maintenance devices, in particular swimming pool cleaning robots, and relates more particularly to an autonomous vacuum cleaning robot with alternating suction for cleaning swimming pools.
Pour nettoyer les piscines et autres bassins artificiels similaires, il est connu d'utiliser des robots de nettoyage, communément appelés robots de piscine, dont la fonction principale est l'aspiration des débris. Il existe différents types de robots de piscine parmi lesquels les robots électriques.To clean swimming pools and other similar artificial basins, it is known to use cleaning robots, commonly called swimming pool robots, the main function of which is the suction of debris. There are different types of pool robots among which are electric robots.
De nombreux robots électriques sont décrits dans l'art antérieur. Ces robots ont connu plusieurs évolutions technologiques et notamment en ce qui concerne leur mobilité, et plus particulièrement, leur orientation automatique pour un balayage intégral de la surface du fond de la piscine. Par exemple, certains robots sont bidirectionnels avec les deux directions de déplacement sensiblement désaxées de sorte à recouvrir efficacement la totalité de la surface de la piscine sans faire d'aller-retour suivant une même direction.Many electric robots are described in the prior art. These robots have undergone several technological evolutions and in particular as regards their mobility, and more particularly, their automatic orientation for a complete sweep of the surface of the bottom of the swimming pool. For example, some robots are bidirectional with the two directions of movement substantially offset so as to effectively cover the entire surface of the swimming pool without going back and forth in the same direction.
Le brevet européen
Ce robot bidirectionnel se déplace alternativement dans deux sens sensiblement opposés, propulsé par la réaction d'un jet d'eau issu d'une tuyère rotative, solidaire de la tourelle, adaptée à prendre deux positions angulaires opposées.This bidirectional robot moves alternately in two substantially opposite directions, propelled by the reaction of a water jet issuing from a rotating nozzle, integral with the turret, adapted to take two opposite angular positions.
Pour ce robot, et plus généralement pour l'ensemble des robots connus, l'aspiration s'opère de façon indépendante du sens de déplacement du robot. La plupart des robots disposent d'une bouche d'aspiration principale par laquelle l'eau entre dans le corps de récupération des débris du robot quel que soit le déplacement de celui-ci.For this robot, and more generally for all the known robots, the suction takes place independently of the direction of movement of the robot. Most robots have a main suction port through which water enters the robot's debris collection body regardless of the movement of the robot.
Certains robots sont pourvus de plusieurs bouches d'aspiration, par exemple deux bouches dont l'une est située à proximité du côté avant du robot et l'autre à l'arrière du robot, pour un passage répété au-dessus de la zone de débris, autrement dit pour des aspirations successives, en vue d'affiner le nettoyage et le ramassage des débris. Néanmoins, la puissance d'aspiration obtenue avec plusieurs bouches reste équivalente à celle qui serait obtenue avec une seule bouche de section égale à la somme des sections desdites bouches. De plus, lorsque la puissance d'aspiration ne suffit pas à « soulever » les débris les plus lourds dès le passage de la première bouche d'aspiration, le passage de la deuxième bouche demeure tout aussi vain, voire à peine plus efficace.Some robots are equipped with several suction ports, for example two mouths, one of which is located near the front side of the robot and the other at the rear of the robot, for repeated passage over the suction area. debris, in other words for successive aspirations, in order to refine cleaning and collection of debris. Nevertheless, the suction power obtained with several mouths remains equivalent to that which would be obtained with a single mouth of section equal to the sum of the sections of said mouths. In addition, when the suction power is not enough to "lift" the heaviest debris as soon as it passes through the first suction mouth, the passage of the second mouth remains just as futile, if not barely more effective.
De ce fait, les deux bouches d'aspiration, comme représentées sur la
Étant donné l'importance de l'emplacement de la bouche d'aspiration, qui doit être située à proximité du bord avant du robot pour récupérer les débris sans qu'ils ne soient dispersés par l'avancée du robot et pour capter les débris en bordure du fond du bassin, il n'est pas judicieux de réaliser une seule bouche qui serait décentrée par rapport au robot.Given the importance of the location of the suction mouth, which must be located near the front edge of the robot to collect the debris without it being dispersed by the advance of the robot and to capture the debris in border of the bottom of the basin, it is not wise to make a single mouth that would be off-center in relation to the robot.
Pour les robots de piscine bidirectionnels avec deux bouches d'aspiration, aucune solution de l'art antérieur ne permet de concentrer automatiquement la totalité de l'aspiration sur une seule bouche d'aspiration, la plus efficace en fonction du sens de déplacement du robot.For bidirectional swimming pool robots with two suction outlets, no solution of the prior art makes it possible to automatically concentrate all of the suction on a single suction mouth, the most efficient according to the direction of movement of the robot. .
En résumé, Les robots de piscine sont équipés d'une ou plusieurs pompes aspirantes et peuvent avoir une ou deux bouches d'aspiration. Une bouche unique, généralement située dans l'axe du robot, ne permet pas de capter efficacement les débris à proximité des murs périphériques par exemple. La solution qui consiste à créer une bouche à chaque extrémité du robot permettrait de résoudre ce problème, mais le fonctionnement simultané de ces deux bouches se traduit par un débit aspiré plus faible au niveau de chaque bouche, et donc par une perte d'efficacité. La conservation de l'efficacité de deux bouches actionnées simultanément impliquerait un doublement de la puissance d'aspiration de la pompe, ce qui augmenterait les coûts, doublerait la consommation d'énergie, et pénaliserait l'autonomie d'un robot alimenté par batterie.In summary, Pool robots are equipped with one or more suction pumps and can have one or two suction ports. A single mouth, generally located in the axis of the robot, does not effectively capture debris near peripheral walls, for example. The solution which consists in creating a mouth at each end of the robot would solve this problem, but the simultaneous operation of these two mouths results in a lower suction flow rate at each mouth, and therefore in a loss of efficiency. Maintaining the efficiency of two mouths operated simultaneously would imply a doubling of the suction power of the pump, which would increase costs, double energy consumption, and penalize the autonomy of a battery-powered robot.
La solution proposée permet de résoudre ce problème sans augmentation de puissance et sans perte d'efficacité en réalisant un robot avec deux bouches d'extrémités à fonctionnement alterné de façon à disposer sur la bouche active de la totalité du débit aspiré par la pompe.The proposed solution makes it possible to solve this problem without increasing power and without losing efficiency by producing a robot with two end openings in alternating operation so as to have on the active mouth all of the flow drawn by the pump.
La présente invention a pour but principal de pallier les limitations de l'art antérieur en proposant un robot de piscine à aspiration alternée, ladite aspiration s'opérant par une seule bouche à la fois en fonction du sens de déplacement dudit robot, améliorant ainsi l'efficacité de l'aspiration et/ou diminuant la consommation énergétique du robot.The main object of the present invention is to overcome the limitations of the prior art by proposing a swimming pool robot with alternating suction, said suction being operated by a single mouth at a time depending on the direction of movement of said robot, thus improving the suction efficiency and / or reducing the energy consumption of the robot.
À cet effet, la présente invention concerne un robot de nettoyage de piscines comportant un corps de collecte de débris, un système de propulsion et d'aspiration apte à déplacer le robot alternativement suivant deux directions sensiblement opposées, et un dispositif d'alimentation, telle qu'une batterie d'alimentation. Ce robot est remarquable en ce que le corps comporte deux compartiments filtrants séparés par une cloison et pourvus chacun d'une entrée d'eau, ladite cloison permettant de concentrer l'aspiration totale du robot dans un compartiment et de la bloquer dans l'autre en fonction de la direction de déplacement du robot.To this end, the present invention relates to a swimming pool cleaning robot comprising a body for collecting debris, a propulsion and suction system capable of moving the robot alternately in two substantially opposite directions, and a supply device, such as than a battery pack. This robot is remarkable in that the body comprises two filter compartments separated by a partition and each provided with a water inlet, said partition allowing to concentrate the total suction of the robot in one compartment and to block it in the other according to the direction of movement of the robot.
Selon un mode de réalisation avantageux, le système de propulsion et d'aspiration et le dispositif d'alimentation sont contenus dans une tourelle rotative et étanche, extérieure au corps du robot, et chaque direction de déplacement du robot est déterminée par une orientation automatique de la tourelle.According to an advantageous embodiment, the propulsion and suction system and the feed device are contained in a rotating and sealed turret, external to the body of the robot, and each direction of movement of the robot is determined by an automatic orientation of the turret.
Selon un autre mode de réalisation, le système de propulsion et d'aspiration comprend deux hélices motorisées, chacune desdites hélices assurant la propulsion du robot dans l'une des directions de déplacement et l'aspiration dans l'un des compartiments filtrants.According to another embodiment, the propulsion and suction system comprises two motorized propellers, each of said propellers ensuring the propulsion of the robot in one of the directions of movement and the suction in one of the filtering compartments.
Avantageusement, le robot comporte une bouche pivotante d'aspiration solidaire de la tourelle, ladite bouche autorisant le passage de l'eau dans un compartiment et bloquant le passage de l'eau dans l'autre compartiment, de sorte à concentrer l'aspiration totale du robot dans un compartiment ou l'autre en fonction de la direction de déplacement du robot.Advantageously, the robot comprises a pivoting suction mouth integral with the turret, said mouth allowing the passage of water into one compartment and blocking the passage of water into the other compartment, so as to concentrate the total suction. of the robot in one compartment or the other depending on the direction of movement of the robot.
Plus particulièrement, la bouche pivotante d'aspiration comporte une ouverture latérale, communicant avec un compartiment à la fois, et une ouverture supérieure communicant avec une sortie d'eau du robot.More particularly, the pivoting suction mouth has a side opening communicating with one compartment at a time, and an upper opening communicating with a water outlet of the robot.
Par exemple, la bouche pivotante d'aspiration est sous forme d'un cylindre creux à base circulaire, l'ouverture latérale étant réalisée au niveau d'un diamètre dudit cylindre et l'ouverture supérieure étant axiale et contiguë à ladite ouverture latérale.For example, the pivoting suction mouth is in the form of a hollow cylinder with a circular base, the lateral opening being made at the level of a diameter of said cylinder and the upper opening being axial and contiguous with said lateral opening.
De façon avantageuse, la bouche pivotante d'aspiration est disposée au-dessus de la cloison de sorte à affleurer un bord supérieur de ladite cloison.Advantageously, the pivoting suction mouth is arranged above the partition so as to be flush with an upper edge of said partition.
La bouche pivotante d'aspiration peut être fixée à la tourelle par vissage.The rotating suction mouth can be screwed onto the turret.
Selon un mode de réalisation, le système de propulsion et d'aspiration est un groupe motopropulseur/pompe électrohydraulique à jet d'eau.According to one embodiment, the propulsion and suction system is an electrohydraulic water jet powertrain / pump.

It is simply used in conjunction with a detailed description of certain embodiments of the invention.
Dans le mode de réalisation décrit ci-après, on fait référence à un robot autonome destiné principalement au nettoyage des piscines. Cet exemple, non limitatif, est donné pour une meilleure compréhension de l'invention et n'exclut pas l'adaptation de l'invention à tout robot de nettoyage pour surfaces immergées dans un liquide ou à une tête d'aspiration équipant un autre appareil tel qu'un balai aspirateur par exemple.In the embodiment described below, reference is made to an autonomous robot intended mainly for cleaning swimming pools. This non-limiting example is given for a better understanding of the invention and does not exclude the adaptation of the invention to any cleaning robot for surfaces immersed in a liquid or to a suction head fitted to another device. such as a vacuum brush for example.
Dans la suite de la description, le terme « robot » ou l'expression « robot de piscine » désignent indifféremment et par extension un robot autonome pour le nettoyage de piscines.In the remainder of the description, the term “robot” or the expression “swimming pool robot” designates indifferently and by extension an autonomous robot for cleaning swimming pools.

Le corps 10 peut présenter une forme et des dimensions quelconques pour s'adapter aux différentes tailles de bassins, de préférence, une forme sensiblement compacte et des dimensions réduites pour un aspect pratique et discret. Selon l'exemple de réalisation illustré, le corps 10 est constitué de deux parties emboitables, la coque supérieure 11 et la coque inférieure 12, facilitant ainsi un démontage du corps 10 pour un accès au volume intérieur dudit corps. Le volume intérieur du corps 10, visible sur la
La tourelle 20 surmonte le corps 10 et contient essentiellement le groupe motopropulseur/pompe électrohydraulique à jet d'eau et la batterie électrique d'alimentation, représentés en trait interrompu sur la
Le terme « tourelle » est ici employé dans son acception générale de dispositif rotatif placé sur un véhicule pour orienter un organe et éventuellement le protéger.The term “turret” is used here in its general sense of a rotary device placed on a vehicle to orient an organ and possibly protect it.
Le groupe motopropulseur/pompe comporte un moteur électrique, des pignons de réduction et une turbine dont la fonction est d'aspirer l'eau, qui entre par les entrées d'eau 40a et 40b et traverse le filtre 13, et de la refouler par une tuyère d'éjection 21 qui débouche de la tourelle 20 pour propulser le robot 100, la direction du refoulement étant sensiblement parallèle au fond de la piscine de sorte à favoriser la propulsion.The power train / pump comprises an electric motor, reduction gears and a turbine whose function is to suck the water, which enters through the
Alternativement, le robot 100 peut, au lieu ou en complément des roues 30, comporter d'autres moyens d'entrainement tels que des rouleaux ou des chenilles.Alternatively, the
Selon un aspect fondamental de l'invention et en référence à la
La cloison 15 est disposée verticalement au niveau d'un plan transversal médian du corps 10, divisant ainsi le corps en deux compartiments de volumes sensiblement égaux. Avantageusement, la cloison 15 présente une épaisseur réduite, de quelques millimètres, pour limiter l'occupation du volume utile de collecte de débris. La cloison 15 présente un bord supérieur affleurant la bouche pivotante d'aspiration 25.The
La bouche pivotante d'aspiration 25 est entrainée en rotation par la tourelle 20 et comporte une ouverture latérale 251 et une ouverture supérieure 252. L'ouverture latérale 251 se place d'un côté ou de l'autre de la cloison 15 suivant l'orientation de la tourelle 20, et par là-même de la bouche pivotante 25, de sorte que ladite bouche communique avec un compartiment 14a ou 14b à la fois, concentrant ainsi l'aspiration au niveau d'une seule entrée d'eau 40a ou 40b. L'ouverture supérieure 252 donne, quant à elle, accès à la tuyère d'éjection 21 du robot.The pivoting
En effet, la bouche pivotante 25 permet à la fois d'autoriser le passage de l'eau au travers d'un compartiment du corps 10 et de s'opposer au passage de l'eau dans l'autre compartiment, et inversement, imposant ainsi la circulation de l'eau dans un seul sens à la manière d'un clapet.In fact, the pivoting
Les ouvertures latérale 251 et supérieure 252 peuvent être séparées, comme sur l'exemple de la
La bouche pivotante 25, selon l'exemple de réalisation de la
La bouche pivotante 25 selon l'invention peut présenter d'autres formes à condition de permettre l'aspiration de l'eau dans un premier compartiment du corps tout en la bloquant dans le second, et ce de façon alternative suivant la rotation de la tourelle.The pivoting
En référence à la
Ainsi, toute la puissance d'aspiration est utilisée au niveau de l'entrée d'eau 14b, au lieu d'être répartie sur les deux entrées comme dans l'art antérieur. De ce fait, la dépression, ou force aspirante, obtenue au niveau de l'entrée 14b est plus importante en raison d'une réduction de la section d'aspiration.Thus, all the suction power is used at the
Lorsque le robot 100 change de sens de déplacement et repart suivant le sens D2, le mécanisme décrit s'inverse et l'aspiration se concentre dans le compartiment 14a qui devient le compartiment avant du robot.When the
La comparaison entre la
Dans le cas de l'aspiration simultanée, la puissance utile disponible P est partagée entre les deux entrées d'eau, qui aspirent chacune avec une puissance utile égale à P/2, à quelques pertes près.In the case of simultaneous suction, the available useful power P is shared between the two water inlets, which each suck with a useful power equal to P / 2, with a few losses.
Dans le cas de l'aspiration alternée, la puissance utile disponible P est totalement réservée à une entrée d'eau à la fois, l'aspiration par l'autre entrée étant bloquée.In the case of alternate suction, the available useful power P is totally reserved for one water inlet at a time, the suction through the other inlet being blocked.
La
Alternativement, la

Compte tenu de l'invention, il apparait clairement que des modifications mineures peuvent être appliquées au robot, et plus particulièrement à la cloison de séparation et/ou à la bouche pivotante d'aspiration, sans pour autant sortir du cadre de l'invention dont l'objet principal est l'aspiration alternée.Taking into account the invention, it clearly appears that minor modifications can be applied to the robot, and more particularly to the partition wall and / or to the pivoting suction mouth, without departing from the scope of the invention, including the main object is alternating aspiration.
