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.

  • 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 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 suction unit is located at least partly above one of the mop supports.

  • 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.
