Definitions

  • the present invention relates to the field of cleaning devices of the vacuum cleaner type and, more particularly to the field of robot vacuum cleaners which can move independently on a surface to be cleaned and make it possible to suck up dust and waste present on the surface to be cleaned.
  • the present invention can for example be tiles, parquet, laminate, carpet or carpet.
  • Vacuum cleaning robots more commonly known as robot vacuum cleaners, have become common nowadays, allowing complete cleaning of a home's surfaces without any user assistance as soon as these surfaces are flat, i.e. on the same level. They thus offer a considerable saving of time to the users to practice other activities.
  • the first and second lateral cleaning brushes make it possible to project waste, present for example near a wall along which the robot vacuum cleaner moves, away from the wall and in particular on the path of movement of the robot vacuum cleaner so that the latter can suck up this waste.
  • the first and second side cleaning brushes wear out quickly and must therefore be replaced regularly.
  • the lengths of the main cleaning brush and the suction opening are necessarily limited (except to increase the bulkiness of the robot vacuum cleaner, which is not desired), which limits the width of the surface that can be cleaned by the robot vacuum cleaner during each of its movements and therefore increases the cleaning time of a given surface .
  • Such an arrangement of the mechanical components belonging to the drive mechanism also makes it necessary to separate the main cleaning brush and the suction opening from the side edges of the main body, which makes it difficult to clean the surfaces located in the immediate vicinity of the obstacles. or walls encountered by the robot vacuum cleaner.
  • first and second side cleaning brushes are ineffective on carpets and rugs. In fact, only the main cleaning brush beats the fibers of a carpet or rug and sucks up the dust retained by these fibers.
  • cables, laces or other elongated and flexible elements are likely to wrap around the first and second side cleaning brushes, which can adversely affect the operation and integrity of the robot vacuum cleaner.
  • the present invention aims to remedy these drawbacks.
  • the technical problem underlying the invention consists in particular in providing a robot vacuum cleaner which is of simple and economical structure, while allowing efficient, rapid and easy cleaning of a surface to be cleaned.
  • the first side cleaning member is fixed with respect to the main body, and the first cleaning part is configured to direct waste, which comes into contact with the first cleaning part when the robot vacuum cleaner moves in the main direction of movement , towards the suction opening.
  • Such a configuration of the first lateral cleaning element which is passive, makes it possible on the one hand to substantially simplify the robot vacuum cleaner, since no drive mechanism capable of driving the first lateral cleaning element is to be provided, and on the other hand to significantly reduce the power consumption of the robot vacuum cleaner and the frequency of replacement of the first side cleaning element.
  • the costs of manufacturing and using the robot vacuum cleaner according to the present invention are therefore substantially limited.
  • the vacuum cleaner robot since the first cleaning part is configured to direct towards the suction opening wastes which are encountered by the first cleaning part when the robot vacuum cleaner moves in the main direction of movement, the vacuum cleaner robot according to the present invention ensures effective cleaning of a surface to be cleaned, including proximity to obstacles encountered by the robot vacuum cleaner.
  • the robot vacuum cleaner object of the present invention is designed, like the majority of robot vacuum cleaners, to effectively clean the floors when it moves in a direction of movement parallel to the longitudinal axis of the robot vacuum cleaner and in a direction of predetermined displacement.
  • the direction of movement parallel to the longitudinal axis of the robot vacuum cleaner and the predetermined direction of movement define the aforementioned main direction of movement of the robot vacuum cleaner which is the subject of the present invention.
  • a front part or a rear part of the main body of the robot vacuum cleaner is identified with respect to the main moving direction of the robot vacuum cleaner.
  • the robot vacuum cleaner may further have one or more of the following features, taken alone or in combination.
  • the robot vacuum cleaner further comprises a second side cleaning element mounted on the front part of the main body and located in the vicinity of a second side edge of the main body, the second cleaning element being fixed relative to the main body and comprising a second cleaning part which is flexible, the first and second cleaning parts being configured to direct waste, which comes into contact with the first and second cleaning parts when the robot vacuum cleaner moves in the main direction of travel, towards the suction opening.
  • the distance between a front edge of the first cleaning part and the median longitudinal plane of the main body is greater than the distance between a rear edge of the first part cleaning area and the median longitudinal plane of the main body.
  • the distance between a front edge of the second cleaning part and the median longitudinal plane of the main body is greater than the distance between a rear edge of the second cleaning part and the median longitudinal plane of the main body.
  • the first and second cleaning parts converge towards each other in the direction of a rear part of the main body.
  • the front edges of the first and second cleaning parts are separated by a first separation distance and the rear edges of the first and second cleaning parts are separated by a second separation distance which is less than the first separation distance.
  • Such a configuration of the first and second cleaning parts promotes the guiding of the waste encountered by the latter towards the suction opening, which further improves the cleaning efficiency of the robot vacuum cleaner according to the present invention.
  • Such a configuration of the first and second cleaning parts also makes it possible to direct the a Vogellic flows under the robot vacuum cleaner from the front of the robot vacuum cleaner towards the suction opening, which promotes the suction of the waste encountered by the robot vacuum cleaner.
  • the first lateral cleaning element is elongated and extends generally in a first direction of extension.
  • the second lateral cleaning element is elongated and extends generally in a second direction of extension.
  • the first and second directions of extension converge towards each other in the direction of the rear part of the main body.
  • the first cleaning part is twisted along the first direction of extension.
  • the second cleaning part is twisted along the second direction of extension.
  • Such a configuration of the first and second cleaning parts makes it possible to vary the inclination of the first and second cleaning parts with respect to the horizontal, in particular to obtain a high opening angle of the first and second cleaning parts and this with first and second cleaning parts of reduced lengths.
  • These arrangements make it possible in particular to bring the rotating cleaning brush closer to the front edge of the main body and also to bring the ends of the rotating cleaning brush closer to the side edges of the main body, and therefore to further improve the cleaning efficiency of the robot vacuum cleaner according to the present invention.
  • the first cleaning part has a generally flat shape.
  • the first cleaning part can also have the form of a wall or a strip.
  • the second cleaning part has a generally flat shape, or has the shape of a wall or a strip.
  • the first and second cleaning parts are arranged symmetrically with respect to the median longitudinal plane of the main body.
