Definitions

  • the present invention relates to the field of vacuum cleaners for vacuuming dust and waste present on a surface to be cleaned, which may be, for example, tiles, parquet flooring, laminate flooring, carpet or rugs.
  • waste guide channel When certain types of waste, such as grains of rice or lentils, enter the waste guide channel from the front opening, this waste is guided, notably by sliding against the two lateral guide walls, to the rear opening, and is then sucked into the suction chamber.
  • waste guide channel When certain types of waste, such as grains of rice or lentils, enter the waste guide channel from the front opening, this waste is guided, notably by sliding against the two lateral guide walls, to the rear opening, and is then sucked into the suction chamber.
  • the angle of inclination of the lower edge of each side guide wall, relative to a transverse direction must be relatively steep to facilitate the sliding of debris towards the rear opening. This steep angle significantly increases the distance between the front edge of the cleaning device and the suction inlet, thereby significantly increasing the size of the cleaning device in front of the suction inlet and consequently reducing the suction efficiency of the cleaning device.
  • the present invention aims to remedy these drawbacks.
  • the technical problem underlying the invention consists in particular of providing a cleaning device which is simple in structure, economical and compact, while exhibiting high cleaning performance.
  • Each of the side guide walls has a lower edge with an inclination, relative to the transverse direction, which increases towards the rear opening, and more particularly from the front opening to the rear opening.
  • Such a configuration of the lower edges of the side guide walls makes it possible on the one hand to limit the speed of movement of waste along the side guide walls, and therefore to limit the risks of saturation of the rear opening, and on the other hand to significantly reduce the risks of accumulation of waste on the side guide walls, and therefore the risks of scratching the surface to be cleaned.
  • the cleaning device according to the present invention ensures efficient guidance of waste, having entered the waste guidance channel from the front opening, towards the rear opening, while limiting the bulk of the cleaning device in front of the suction mouth.
  • the cleaning device may also have one or more of the following characteristics, taken alone or in combination.
  • the cleaning device is a vacuum cleaner nozzle or an autonomous cleaning robot, and more particularly a robot vacuum cleaner.
  • the waste guide channel has a width, measured parallel to the transverse direction, which decreases towards the rear opening, and more particularly from the front opening to the rear opening.
  • the two lateral guide walls each extend from the front opening to the rear opening.
  • the waste guidance channel extends under a front part of the main body.
  • the cleaning device comprises a single waste guidance channel, and therefore a single rear opening.
  • This configuration of the cleaning device limits the number of passes through the underside of the main body, thereby enhancing the suction effect (depression) generated by the cleaning device and thus improving its cleaning performance.
