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 lateral guide walls comprises a first lateral guide surface and a second lateral guide surface, which are substantially flat and inclined relative to each other.
  • the first two lateral guide surfaces converge towards each other in the direction of the rear opening, while the second two lateral guide surfaces are positioned between the first two and also converge towards each other in the direction of the rear opening.
  • the first and second lateral guide surfaces of each lateral guide wall are inclined relative to each other at an angle greater than 5°, advantageously greater than 10°.
  • Such a relative inclination between the first and second lateral guide surfaces of the same lateral guide wall allows, on the one hand, to limit the speed of movement of waste along the lateral guide walls (since at least a portion of each lateral guide wall has an inclination, relative to the transverse direction, which is reduced), 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 lateral guide walls (since at least a portion of each lateral guide wall has an inclination, relative to the transverse direction, which is greater), 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 (due to the difference in inclination, relative to the transverse direction, of the first and second lateral guide surfaces of each lateral guide wall).
  • a substantially flat lateral guide surface is defined as a lateral guide surface extending between two theoretical (fictitious) planes that are parallel and separated by less than 5 mm, preferably less than 2.5 mm. This tolerance is also known as flatness deviation or flatness defect.
  • the angle of inclination, between said first and second lateral guide surfaces corresponds to the angle of inclination between a first average extension plane defined by said respective first lateral guide surface and a second average extension plane defined by said second lateral guide surface.
  • the cleaning device may also have one or more of the following features: the following characteristics, taken alone or in combination.
  • the first and second lateral guide surfaces of the same lateral guide wall are different and have different profiles, such that a superposition of said first and second lateral guide surfaces does not allow one of said first and second lateral guide surfaces to be confused with the other of said first and second lateral guide surfaces.
  • each of the first and second lateral guide surfaces is flat.
  • each of the first and second lateral guide surfaces is twisted longitudinally, such that the two lateral edges of the same first lateral guide surface have, with respect to the horizontal, a different inclination and for example a difference in inclination of less than 20° (and advantageously less than 15° and for example of about 10°), and such that the two lateral edges of the same second lateral guide surface have, with respect to the horizontal, a different inclination and for example a difference in inclination of less than 20°.
  • each first lateral guide surface is concave, and/or each second lateral guide surface is concave.
  • the cleaning device is a vacuum cleaner nozzle or an autonomous cleaning robot, and more particularly a robot vacuum cleaner.
  • the angle of inclination between the first and second lateral guide surfaces of the same lateral guide wall is between 10 and 25°, and for example between 10 and 15°.
  • each first guiding surface lateral forms a first lateral guide ramp
  • each second lateral guide surface forms a second lateral guide ramp
  • each of the first and second lateral guide surfaces has a lower edge that is substantially straight.
  • the lower edge of each first lateral guide surface is inclined, relative to the transverse direction, at a first angle of inclination
  • the lower edge of each second lateral guide surface is inclined, relative to the transverse direction, at a second angle of inclination that is greater than the first angle of inclination.
  • a substantially straight lower edge is defined as a lower edge formed by a line that lies within a fictitious cylinder with a diameter of less than 1 mm, preferably less than 0.5 mm.
  • the first angle of inclination is between 1 and 30°, advantageously between 1 and 10°, even more advantageously between 1 and 5°, and for example between 1 and 3°.
  • Such a configuration of the lower edges of the first guide surfaces makes it possible to further reduce the risks of saturation of the rear opening.
  • the second angle of inclination is between 15 and 90°, advantageously between 15 and 30°, and for example approximately 20°.
  • Such a configuration of the lower edges of the second guide surfaces further reduces the risk of debris accumulating on the lateral guide walls.
  • 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 lower edge of each of the lateral guide walls is configured to extend substantially horizontally when the cleaning device rests on a horizontal surface.
  • the front opening is substantially centered with respect to the median longitudinal plane of the main body.

  • the rear opening has a width, measured parallel to the transverse direction, of between 1 and 10% of the width, measured parallel to the transverse direction, of the front opening.
  • a width of the rear opening makes it possible to maintain high suction performance at the suction inlet.
  • the rear opening has a width, measured parallel to the transverse direction, which is less than the width, measured parallel to the transverse direction, of each of the second lateral guide surfaces.
  • each first lateral guide surface is configured to be inclined relative to the horizontal at a first angle of inclination between 20° and 60°, advantageously between 40° and 60°, and for example between 40° and 55°, when the cleaning device rests on a horizontal surface.
  • a first angle of inclination between 20° and 60°, advantageously between 40° and 60°, and for example between 40° and 55°, when the cleaning device rests on a horizontal surface.

  • mean slope angle means the average of the different slope angle values measured along the respective lateral guide surface.
