Definitions

  • the present invention relates to the field of autonomous cleaning devices equipped with a wet cleaning device, and more particularly to the field of robot vacuum cleaners which can move autonomously over a surface to be cleaned and which can suck up dust and waste.
  • present on the surface to be cleaned which may for example be tiles, parquet, laminate, carpet or a rug, and possibly washing the surface to be cleaned simultaneously with a vacuuming operation.
  • a cleaning robot comprising a main body, a suction unit, a wet cleaning device is known from the document US-A-2020383547 .
  • the present invention aims to remedy these drawbacks.
  • the technical problem underlying the invention consists in particular of providing an autonomous cleaning robot which is simple, economical and compact in structure, while having high cleaning performance.
  • the two mop supports are located behind the axes of rotation of the drive wheels, and the direction of translation extends substantially parallel to the axes of rotation of the two drive wheels. In other words, the direction of translation extends transversely to a main direction of movement of the autonomous cleaning robot.
  • Such an arrangement of the mop supports namely at the rear of the axes of rotation of the driving wheels, makes it possible to increase the support force exerted by each of the mops on the surface to be cleaned, and therefore to increase the friction of the mop. wet cleaning device on the surface to be cleaned, due to the weight exerted by the main body on the wet cleaning device.
  • Such an arrangement of the mop supports increases the scraping efficiency of the wet cleaning device on the floor and therefore the cleaning quality of the autonomous cleaning robot.
  • transverse movement of the mop supports also limits the length of the autonomous cleaning robot, while optimizing the surface of the mops which will be seen by a task when the autonomous cleaning robot moves. Indeed, due to the alternating movements of the mop supports and the proximity of the driving wheels, it would be necessary either to reduce the dimensions of the mops in a longitudinal direction so as not to impact the longitudinal dimensions of the autonomous cleaning robot (which would be detrimental for the cleaning quality of the autonomous cleaning robot), or to increase the dimensions of the autonomous cleaning robot to allow longitudinal movements of large mops.
  • the autonomous cleaning robot which is the subject of the present invention is designed, like the majority of autonomous cleaning robots, to effectively clean floors when it moves in a direction of movement parallel to the longitudinal axis of the autonomous cleaning robot and according to a predetermined direction of movement.
  • the direction of movement parallel to the longitudinal axis of the autonomous cleaning robot and the predetermined direction of movement define a main direction of movement of the autonomous cleaning robot which is the subject of the present invention.
  • a front part or a rear part of the main body of the autonomous cleaning robot is identified with respect to the main movement direction of the autonomous cleaning robot.

  • the autonomous cleaning robot comprises a translation drive mechanism configured to translate the mop supports in the direction of translation, and preferably according to reciprocating movements.
  • the translation drive mechanism is configured to move the mop supports in translation in the direction of translation and alternately between the close configuration and the distant configuration.
  • the translation drive mechanism is located at least partly above one of the mop supports.
  • the translation drive mechanism is configured to move the two mop supports in translation in opposition to phase.
  • the translation drive mechanism is configured to translate the two mop supports in alternating movements and in opposite directions of movement.
  • each of the mops is configured to exert a pressing force on the surface to be cleaned when the autonomous cleaning robot rests on the surface to be cleaned.
  • the support force is greater than 5 N, and for example greater than or equal to 9 N.
  • the two mop supports are arranged on either side of a median longitudinal plane of the main body.
  • median longitudinal plane means a vertical plane which is parallel to the main direction of movement and which divides the main body into two substantially equal parts.
  • the autonomous cleaning robot is configured such that, when the autonomous cleaning robot rests on a surface to be cleaned, a rear part of the autonomous cleaning robot rests on said surface to be cleaned directly by the two mops.
  • a configuration of the autonomous cleaning robot allows the mops to directly take up at least part of the mass of the autonomous cleaning robot, and therefore to further increase the support force exerted by each of the mops on the floor to be cleaned.
  • Such a configuration of the autonomous cleaning robot makes it possible to further improve the cleaning quality of the autonomous cleaning robot.
  • the two mop supports are positioned relative to the main body such that the two mop supports are not cut by any vertical plane passing through the rotation axes of the wheels equipping the robot with autonomous cleaning, and such that the two mop supports are not located at least partly between two vertical planes passing respectively through two axes of rotation of wheels equipping the autonomous cleaning robot.
  • Such a configuration of the autonomous cleaning robot also allows the mops to directly take up at least part of the mass of the autonomous cleaning robot, and therefore to further improve the cleaning quality of the autonomous cleaning robot.
  • the mop supports were cut by a vertical plane passing through the rotation axes of the wheels fitted to the autonomous cleaning robot (and for example two driving wheels) or arranged between wheels of the autonomous cleaning robot whose axes of rotation are parallel (for example between the axes of rotation of the driving wheels and the axis of rotation of a rear wheel), the forces resulting from the mass of the autonomous cleaning robot would be picked up by the wheels and not by the mop supports.
  • the autonomous cleaning robot does not have an additional wheel located behind the axes of rotation of the two drive wheels.

  • the power battery is located entirely above one of the mop supports.
  • the suction unit is located at least partly above one of the mop supports.
  • Such an arrangement of the suction unit makes it possible to increase the support force exerted by at least one of the mops on the surface to be cleaned, and therefore to further increase the scraping efficiency of the wet cleaning device on the floor and thus the cleaning quality of the autonomous cleaning robot.
  • the suction unit comprises a suction motor and a fan which is coupled to the suction motor and which is configured to generate the air flow through the opening of aspiration.
  • the center of gravity of the suction unit is located above one of the mop supports.
  • the suction unit is located entirely above one of the mop supports.

Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine des appareils de nettoyage autonome équipé d'un dispositif de nettoyage humide, et plus particulièrement au domaine des aspirateurs robots pouvant se déplacer de manière autonome sur une surface à nettoyer et permettant d'aspirer des poussières et des déchets présents sur la surface à nettoyer, qui peut par exemple être du carrelage, du parquet, du stratifié, de la moquette ou un tapis, et éventuellement de laver la surface à nettoyer simultanément à une opération d'aspiration.The present invention relates to the field of autonomous cleaning devices equipped with a wet cleaning device, and more particularly to the field of robot vacuum cleaners which can move autonomously over a surface to be cleaned and which can suck up dust and waste. present on the surface to be cleaned, which may for example be tiles, parquet, laminate, carpet or a rug, and possibly washing the surface to be cleaned simultaneously with a vacuuming operation.

Etat de la techniqueState of the art

Les robots de nettoyage autonomes sont devenus d'un usage commun de nos jours, ceux-ci permettant de nettoyer des surfaces complètes d'une habitation sans aucune assistance de l'utilisateur dès l'instant où ces surfaces sont planes, c'est-à-dire sur un même niveau. Ils offrent ainsi un gain de temps considérable aux utilisateurs pour pratiquer d'autres activités.Autonomous cleaning robots have become common use today, making it possible to clean entire surfaces of a home without any assistance from the user as long as these surfaces are flat, i.e. that is to say on the same level. They thus offer considerable time savings to users to practice other activities.

Le document EP3257416A1 divulgue un robot de nettoyage autonome comprenant :

  • un corps principal comportant une face inférieure qui est configurée pour être orientée vers une surface à nettoyer et une ouverture d'aspiration prévue dans une partie avant du corps principal et débouchant dans la face inférieure du corps principal,
  • un dispositif de nettoyage humide comportant deux supports de serpillère qui sont chacun montés mobiles en translation par rapport au corps principal selon une direction de translation, et deux serpillères montées de manière amovible respectivement sur les deux supports de serpillère, les serpillères étant configurées pour être en contact avec la surface à nettoyer, et
  • deux roues motrices configurées pour rouler sur la surface à nettoyer et montées mobiles en rotation sur le corps principal respectivement autour de deux axes de rotation qui sont sensiblement parallèles.
Selon le document EP3257416A1 , les deux supports de serpillère sont montés respectivement sur une partie avant du corps principal et sur une partie arrière du corps principal, et sont disposés de part et d'autre des axes de rotation des roues motrices. En outre, selon le document EP3257416A1 , la direction de translation des supports de serpillère s'étend parallèlement à une direction de déplacement principale du robot de nettoyage autonome, c'est-à-dire selon une direction longitudinale du robot de nettoyage autonome.The document EP3257416A1 discloses an autonomous cleaning robot comprising:
  • a main body comprising a lower face which is configured to be oriented towards a surface to be cleaned and a suction opening provided in a front part of the main body and opening into the lower face of the main body,
  • a wet cleaning device comprising two mop supports which are each mounted movable in translation relative to the main body in a direction of translation, and two mops mounted in a removable manner respectively on the two mop supports, the mops being configured to be in contact with the surface to be cleaned, and
  • two driving wheels configured to roll on the surface to be cleaned and mounted movable in rotation on the main body respectively around two axes of rotation which are substantially parallel.
According to the document EP3257416A1 , the two mop supports are mounted respectively on a front part of the main body and on a rear part of the main body, and are arranged on either side of the axes of rotation of the drive wheels. Furthermore, according to the document EP3257416A1 , the direction of translation of the mop supports extends parallel to a main direction of movement of the autonomous cleaning robot, that is to say in a longitudinal direction of the autonomous cleaning robot.

Le fait que les supports de serpillère se déplacent parallèlement à la direction de déplacement principale du robot de nettoyage humide augmente sensiblement les risques de patinage des roues motrices sur la surface à nettoyer lorsque les serpillères n'exercent pas les mêmes forces de frottement sur le sol à nettoyer (par exemple en raison d'une usure ou d'un encrassement différents d'une serpillère par rapport à l'autre, ou d'un déplacement des deux serpillères sur deux surfaces à nettoyer différentes).The fact that the mop supports move parallel to the main direction of movement of the wet cleaning robot significantly increases the risk of the drive wheels slipping on the surface to be cleaned when the mops do not exert the same friction forces on the floor to be cleaned (for example due to different wear or dirt on one mop compared to the other, or due to movement of the two mops on two different surfaces to be cleaned).

Or, de tels patinages sont susceptibles de nuire à la navigation autonome du robot de nettoyage autonome, nécessitant alors au robot de nettoyage autonome de stopper l'opération de nettoyage en cours et de communiquer avec sa station d'accueil pour se repositionner dans l'espace (ce qui augmente la durée de nettoyage d'un sol et réduit les performances de nettoyage du robot de nettoyage autonome). Pour pallier un tel inconvénient, il pourrait être envisagé d'équiper le robot de nettoyage autonome d'une unité de commande plus complexe et onéreuse (qui serait capable de tenir compte des patinages précitées pour contrôler la navigation du robot de nettoyage autonome), ce qui augmenterait toutefois sensiblement les coûts de fabrication du robot de nettoyage autonome.
En outre, en raison de la disposition des supports de serpillère respectivement à l'avant et à l'arrière des roues motrices, les forces d'appui exercées sur le sol à nettoyer par chacune des serpillères sont faibles car ces forces d'appui sont reprises principalement par les roues latérales disposées entre les deux supports de serpillère, ce qui limite les performances de nettoyage du robot de nettoyage décrit dans le document EP3257416A1 . Un robot de nettoyage comprenant un corps principal, une unité d'aspiration, un dispositif de nettoyage humide est connu du document US-A-2020383547 .However, such slippage is likely to harm the autonomous navigation of the autonomous cleaning robot, requiring the autonomous cleaning robot to stop the cleaning operation in progress and to communicate with its docking station to reposition itself in the space (which increases the cleaning time of a floor and reduces the cleaning performance of the autonomous cleaning robot). To overcome such a drawback, it could be envisaged to equip the autonomous cleaning robot with a more complex and expensive control unit (which would be capable of taking into account the aforementioned slippage to control the navigation of the autonomous cleaning robot), this which would, however, significantly increase the manufacturing costs of the robot autonomous cleaning.
In addition, due to the arrangement of the mop supports respectively at the front and rear of the driving wheels, the support forces exerted on the floor to be cleaned by each of the mops are low because these support forces are taken up mainly by the side wheels arranged between the two mop supports, which limits the cleaning performance of the cleaning robot described in the document EP3257416A1 . A cleaning robot comprising a main body, a suction unit, a wet cleaning device is known from the document US-A-2020383547 .

Résumé de l'inventionSummary of the invention

La présente invention vise à remédier à ces inconvénients.The present invention aims to remedy these drawbacks.

Le problème technique à la base de l'invention consiste notamment à fournir un robot de nettoyage autonome qui soit de structure simple, économique et compacte, tout en présentant des performances de nettoyage élevées.The technical problem underlying the invention consists in particular of providing an autonomous cleaning robot which is simple, economical and compact in structure, while having high cleaning performance.

A cet effet, l'invention a pour objet un robot de nettoyage autonome comprenant :

  • un corps principal comportant une face inférieure qui est configurée pour être orientée vers une surface à nettoyer et une ouverture d'aspiration prévue dans une partie avant du corps principal et débouchant dans la face inférieure du corps principal,
  • une unité d'aspiration qui est logée au moins en partie dans le corps principal et qui est configurée pour générer un flux d'air à travers l'ouverture d'aspiration,
  • un dispositif de nettoyage humide comportant deux supports de serpillère qui sont chacun montés mobiles en translation par rapport au corps principal selon une direction de translation, et deux serpillères montées de manière amovible respectivement sur les deux supports de serpillère, les serpillères étant configurées pour être en contact avec la surface à nettoyer, et
  • deux roues motrices configurées pour rouler sur la surface à nettoyer et montées mobiles en rotation sur le corps principal respectivement autour de deux axes de rotation qui sont sensiblement parallèles.
To this end, the subject of the invention is an autonomous cleaning robot comprising:
  • a main body comprising a lower face which is configured to be oriented towards a surface to be cleaned and a suction opening provided in a front part of the main body and opening into the lower face of the main body,
  • a suction unit which is housed at least partly in the main body and which is configured to generate an air flow through the suction opening,
  • a wet cleaning device comprising two mop supports which are each mounted movable in translation relative to the main body in a translation direction, and two mops removably mounted respectively on the two mop supports, the mops being configured to be in contact with the surface to be cleaned, and
  • two driving wheels configured to roll over the surface to be cleaned and mounted movable in rotation on the main body respectively around two axes of rotation which are substantially parallel.

Les deux supports de serpillère sont situés à l'arrière des axes de rotation des roues motrices, et la direction de translation s'étend sensiblement parallèlement aux axes de rotation des deux roues motrices. En d'autre termes, la direction de translation s'étend transversalement à une direction de déplacement principale du robot de nettoyage autonome.The two mop supports are located behind the axes of rotation of the drive wheels, and the direction of translation extends substantially parallel to the axes of rotation of the two drive wheels. In other words, the direction of translation extends transversely to a main direction of movement of the autonomous cleaning robot.

Une telle disposition des supports de serpillère, à savoir à l'arrière des axes de rotation des roues motrices, permet d'augmenter la force d'appui exercée par chacune des serpillères sur la surface à nettoyer, et donc d'augmenter les frottements du dispositif de nettoyage humide sur la surface à nettoyer, du fait du poids exercé par le corps principal sur le dispositif de nettoyage humide. Ainsi, une telle disposition des supports de serpillère augmente l'efficacité de grattage du dispositif de nettoyage humide sur le sol et donc la qualité de nettoyage du robot de nettoyage autonome.Such an arrangement of the mop supports, namely at the rear of the axes of rotation of the driving wheels, makes it possible to increase the support force exerted by each of the mops on the surface to be cleaned, and therefore to increase the friction of the mop. wet cleaning device on the surface to be cleaned, due to the weight exerted by the main body on the wet cleaning device. Thus, such an arrangement of the mop supports increases the scraping efficiency of the wet cleaning device on the floor and therefore the cleaning quality of the autonomous cleaning robot.

De plus, une telle disposition des supports de serpillère permet d'éviter aux roues motrices de rouler sur une zone humide venant d'être nettoyée par les serpillères, et donc d'éviter l'apparition de traces qui seraient susceptibles de nuire à la qualité du nettoyage réalisé.In addition, such an arrangement of the mop supports makes it possible to prevent the drive wheels from rolling over a wet area which has just been cleaned by the mops, and therefore to avoid the appearance of traces which would be likely to harm the quality. cleaning carried out.

En outre, le fait que les supports de serpillère se déplacent parallèlement aux axes de rotation des deux roues motrices, c'est-à-dire transversalement à la direction de déplacement principale du robot de nettoyage humide, et non pas par exemple parallèlement à la direction de déplacement principale, limite sensiblement les risques de patinage des roues motrices sur la surface à nettoyer lorsque les serpillères n'exercent pas les mêmes forces de frottement sur le sol à nettoyer (par exemple en raison d'une usure ou d'un encrassement différents d'une serpillère par rapport à l'autre, ou d'un déplacement des deux serpillères sur deux surfaces à nettoyer différentes).Furthermore, the fact that the mop supports move parallel to the axes of rotation of the two driving wheels, that is to say transversely to the main direction of movement of the wet cleaning robot, and not for example parallel to the main direction of movement, significantly limits the risk of slipping of the drive wheels on the surface to be cleaned when the mops do not exert the same friction forces on the floor to be cleaned (for example due to wear or clogging different from one mop to the other, or from moving the two mops on two different surfaces to be cleaned).

Comparativement à un robot de nettoyage autonome équipé de supports de serpillère se déplaçant longitudinalement, un déplacement transversal des supports de serpillère limite également l'encombrement en longueur du robot de nettoyage autonome, tout en optimisant la surface des serpillères qui sera vue par une tâche lors d'un déplacement du robot de nettoyage autonome. En effet, en raison des mouvements alternatifs des supports de serpillère et de la proximité des roues motrices, il serait nécessaire soit de réduire les dimensions des serpillères selon une direction longitudinale de manière à ne pas impacter l'encombrement longitudinal du robot de nettoyage autonome (ce qui serait préjudiciable pour la qualité de nettoyage du robot de nettoyage autonome), soit d'augmenter les dimensions du robot de nettoyage autonome pour permettre des déplacements longitudinaux de serpillères de grandes dimensions.Compared to an autonomous cleaning robot equipped with supports mop moving longitudinally, transverse movement of the mop supports also limits the length of the autonomous cleaning robot, while optimizing the surface of the mops which will be seen by a task when the autonomous cleaning robot moves. Indeed, due to the alternating movements of the mop supports and the proximity of the driving wheels, it would be necessary either to reduce the dimensions of the mops in a longitudinal direction so as not to impact the longitudinal dimensions of the autonomous cleaning robot ( which would be detrimental for the cleaning quality of the autonomous cleaning robot), or to increase the dimensions of the autonomous cleaning robot to allow longitudinal movements of large mops.

Le robot de nettoyage autonome objet de la présente invention est conçu, comme la majorité des robots de nettoyage autonome, pour nettoyer efficacement les sols lorsqu'il se déplace selon une direction de déplacement parallèle à l'axe longitudinal du robot de nettoyage autonome et selon un sens de déplacement prédéterminé. La direction de déplacement parallèle à l'axe longitudinal du robot de nettoyage autonome et le sens de déplacement prédéterminé définissent une direction de déplacement principale du robot de nettoyage autonome objet de la présente invention. Ainsi, une partie avant ou une partie arrière du corps principal du robot de nettoyage autonome est identifiée par rapport à la direction de déplacement principale du robot de nettoyage autonome.The autonomous cleaning robot which is the subject of the present invention is designed, like the majority of autonomous cleaning robots, to effectively clean floors when it moves in a direction of movement parallel to the longitudinal axis of the autonomous cleaning robot and according to a predetermined direction of movement. The direction of movement parallel to the longitudinal axis of the autonomous cleaning robot and the predetermined direction of movement define a main direction of movement of the autonomous cleaning robot which is the subject of the present invention. Thus, a front part or a rear part of the main body of the autonomous cleaning robot is identified with respect to the main movement direction of the autonomous cleaning robot.

Le robot de nettoyage autonome peut en outre présenter une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison.The autonomous cleaning robot may further have one or more of the following characteristics, taken alone or in combination.

Selon un mode de réalisation de l'invention, l'ouverture d'aspiration est située à l'avant des axes de rotation des roues motrices.According to one embodiment of the invention, the suction opening is located in front of the axes of rotation of the drive wheels.

Selon un mode de réalisation de l'invention, les deux supports de serpillère sont disposés côté à côté.According to one embodiment of the invention, the two mop supports are arranged side by side.

Selon un mode de réalisation de l'invention, les axes de rotation des deux roues motrices sont colinéaires.According to one embodiment of the invention, the axes of rotation of the two driving wheels are collinear.

Selon un mode de réalisation de l'invention, le dispositif de nettoyage humide est disposé dans une partie arrière du corps principal.According to one embodiment of the invention, the wet cleaning device is arranged in a rear part of the main body.

Selon un mode de réalisation de l'invention, les supports de serpillère sont montés mobiles l'un par rapport à l'autre entre une configuration rapprochée dans laquelle les deux supports de serpillère sont rapprochés l'un de l'autre et une configuration éloignée dans laquelle les deux supports de serpillère sont éloignés l'un de l'autre.According to one embodiment of the invention, the mop supports are mounted movable relative to each other between a close configuration in which the two mop supports are brought closer to each other and a distant configuration in which the two mop supports are spaced apart from each other.

Selon un mode de réalisation de l'invention, le robot de nettoyage autonome comporte un mécanisme d'entraînement en translation configuré pour déplacer en translation les supports de serpillère selon la direction de translation, et de préférence selon des mouvements alternatifs.According to one embodiment of the invention, the autonomous cleaning robot comprises a translation drive mechanism configured to translate the mop supports in the direction of translation, and preferably according to reciprocating movements.

Selon un mode de réalisation de l'invention, le mécanisme d'entraînement en translation est configuré pour déplacer en translation les supports de serpillère selon la direction de translation et alternativement entre la configuration rapprochée et la configuration éloignée.According to one embodiment of the invention, the translation drive mechanism is configured to move the mop supports in translation in the direction of translation and alternately between the close configuration and the distant configuration.

Selon un mode de réalisation de l'invention, le mécanisme d'entraînement en translation est situé au moins en partie au-dessus de l'un des supports de serpillère.According to one embodiment of the invention, the translation drive mechanism is located at least partly above one of the mop supports.

Selon un mode de réalisation de l'invention, le mécanisme d'entraînement en translation est configuré pour déplacer en translation les deux supports de serpillère en opposition de phase. En d'autres termes, le mécanisme d'entraînement en translation est configuré pour déplacer en translation les deux supports de serpillère selon des mouvements alternatifs et dans des sens de déplacement opposés.According to one embodiment of the invention, the translation drive mechanism is configured to move the two mop supports in translation in opposition to phase. In other words, the translation drive mechanism is configured to translate the two mop supports in alternating movements and in opposite directions of movement.

Selon un mode de réalisation de l'invention, chacune des serpillères est configurée pour exercer une force d'appui sur la surface à nettoyer lorsque le robot de nettoyage autonome repose sur la surface à nettoyer. Avantageusement, la force d'appui est supérieure à 5 N, et par exemple supérieure ou égale à 9 N.According to one embodiment of the invention, each of the mops is configured to exert a pressing force on the surface to be cleaned when the autonomous cleaning robot rests on the surface to be cleaned. Advantageously, the support force is greater than 5 N, and for example greater than or equal to 9 N.

Selon un mode de réalisation de l'invention, les deux supports de serpillère sont disposés de part et d'autre d'un plan longitudinal médian du corps principal. Dans le présent document, on entend par « plan longitudinal médian », un plan vertical qui est parallèle à la direction de déplacement principale et qui divise le corps principal en deux parties sensiblement égales.According to one embodiment of the invention, the two mop supports are arranged on either side of a median longitudinal plane of the main body. In this document, the term “median longitudinal plane” means a vertical plane which is parallel to the main direction of movement and which divides the main body into two substantially equal parts.

Selon un mode de réalisation de l'invention, le robot de nettoyage autonome est configuré de telle sorte que, lorsque le robot de nettoyage autonome repose sur une surface à nettoyer, une partie arrière du robot de nettoyage autonome repose sur ladite surface à nettoyer directement par les deux serpillères. Une telle configuration du robot de nettoyage autonome permet aux serpillères de reprendre directement au moins une partie de la masse du robot de nettoyage autonome, et donc d'augmenter encore la force d'appui exercer par chacune des serpillères sur le sol à nettoyer. Ainsi, une telle configuration du robot de nettoyage autonome permet d'améliorer encore la qualité de nettoyage du robot de nettoyage autonome.According to one embodiment of the invention, the autonomous cleaning robot is configured such that, when the autonomous cleaning robot rests on a surface to be cleaned, a rear part of the autonomous cleaning robot rests on said surface to be cleaned directly by the two mops. Such a configuration of the autonomous cleaning robot allows the mops to directly take up at least part of the mass of the autonomous cleaning robot, and therefore to further increase the support force exerted by each of the mops on the floor to be cleaned. Thus, such a configuration of the autonomous cleaning robot makes it possible to further improve the cleaning quality of the autonomous cleaning robot.

Selon un mode de réalisation de l'invention, les deux supports de serpillère sont positionnés par rapport au corps principal de telle sorte que les deux supports de serpillère ne sont coupés par aucun plan vertical passant par des axes de rotation de roues équipant le robot de nettoyage autonome, et de telle sorte que les deux supports de serpillère ne sont pas situés au moins en partie entre deux plans verticaux passant respectivement par deux axes de rotation de roues équipant le robot de nettoyage autonome. Une telle configuration du robot de nettoyage autonome permet également aux serpillères de reprendre directement au moins une partie de la masse du robot de nettoyage autonome, et donc d'améliorer encore la qualité de nettoyage du robot de nettoyage autonome. Au contraire, si les supports de serpillère étaient coupés par un plan vertical passant par des axes de rotation de roues équipant le robot de nettoyage autonome (et par exemple des deux roues motrices) ou disposés entre des roues du robot de nettoyage autonome dont les axes de rotation sont parallèles (par exemple entre les axes de rotation des roues motrices et l'axe de rotation d'une roue arrière), les forces résultants de la masse du robot de nettoyage autonome seraient reprises par les roues et non par les supports de serpillère.According to one embodiment of the invention, the two mop supports are positioned relative to the main body such that the two mop supports are not cut by any vertical plane passing through the rotation axes of the wheels equipping the robot with autonomous cleaning, and such that the two mop supports are not located at least partly between two vertical planes passing respectively through two axes of rotation of wheels equipping the autonomous cleaning robot. Such a configuration of the autonomous cleaning robot also allows the mops to directly take up at least part of the mass of the autonomous cleaning robot, and therefore to further improve the cleaning quality of the autonomous cleaning robot. On the contrary, if the mop supports were cut by a vertical plane passing through the rotation axes of the wheels fitted to the autonomous cleaning robot (and for example two driving wheels) or arranged between wheels of the autonomous cleaning robot whose axes of rotation are parallel (for example between the axes of rotation of the driving wheels and the axis of rotation of a rear wheel), the forces resulting from the mass of the autonomous cleaning robot would be picked up by the wheels and not by the mop supports.

Le robot de nettoyage autonome 2 comprend un corps principal 3 comportant une face inférieure 4 qui est configurée pour être orientée vers la surface à nettoyer, et une ouverture d'aspiration 5 qui est prévue dans une partie avant 3.1 du corps principal 3 et qui débouche dans la face inférieure 4 du corps principal 3. De façon avantageuse, l'ouverture d'aspiration 5 est allongée et s'étend transversalement, et plus particulièrement perpendiculairement, à une direction de déplacement principale D du robot de nettoyage autonome 2.The autonomous cleaning robot 2 comprises a main body 3 having a lower face 4 which is configured to be oriented towards the surface to be cleaned, and a suction opening 5 which is provided in a part front 3.1 of the main body 3 and which opens into the lower face 4 of the main body 3. Advantageously, the suction opening 5 is elongated and extends transversely, and more particularly perpendicularly, to a main direction of movement D of the autonomous cleaning robot 2.

Le robot de nettoyage autonome 2 comprend de plus une brosse de nettoyage rotative 6 montée mobile en rotation dans le corps principal 3 autour d'un axe de rotation de brosse qui s'étend transversalement, et plus particulièrement perpendiculairement, à la direction de déplacement principale D. De façon avantageuse, l'axe de rotation de brosse est sensiblement horizontal lorsque le robot de nettoyage autonome 2 repose sur une surface horizontale.The autonomous cleaning robot 2 further comprises a rotating cleaning brush 6 mounted to rotate in the main body 3 around a brush rotation axis which extends transversely, and more particularly perpendicularly, to the main direction of movement D. Advantageously, the brush rotation axis is substantially horizontal when the autonomous cleaning robot 2 rests on a horizontal surface.

Ainsi, le robot de nettoyage autonome 2 comprend deux mécanismes d'entraînement en rotation 8 logés dans le corps principal 3 et configurés chacun pour entraîner en rotation une roue motrice 7 respective parmi les deux roues motrices 7. Chaque mécanisme d'entraînement en rotation 8 comporte un moteur d'entraînement couplé en rotation à la roue motrice 7 respective et disposé par exemple dans une partie latérale respective du corps principal 3. Selon la commande des deux moteurs d'entraînement précités, le corps principal 3 peut pivoter à gauche, à droite ou sur lui-même, avancer ou encore reculer.The two driving wheels 7 are advantageously motorized independently of each other.
