Definitions

  • the present invention relates to the field of vacuum cleaners equipped with a suction head making it possible to suck up dust and waste present on a surface to be cleaned.
  • Vacuum cleaners equipped with a suction head are well known on the market, these allowing surfaces to be cleaned by suction to remove dust and waste resting on them.
  • the surface to be vacuumed can, for example, be tiles, parquet, laminate, carpet or a rug.
  • a suction head comprises in a known manner a main body comprising a sole provided with a lower face intended to be positioned adjacent to the surface to be vacuumed during use of the suction head, and with a mouth suction opening into the underside of the sole.
  • the main function of the row of bristles is to scrape the floor to be cleaned, particularly when the floor to be cleaned is a soft floor, such as carpet or rug, while the protective strip has the function of limiting tangling. hair or similar debris around the brush body.
  • the tangential speeds at the free ends of the bristles and the free end of the cleaning blade can be higher or lower.
  • the dust particles projected by the fibers of the blade carpet after the scraping action are likely to fall by gravity onto the floor before being dragged by the protective strip towards the suction mouth or are likely to be thrown into the air after the passage of the strip cleaning, and therefore behind the protective slat.
  • the present invention aims to remedy all or part of these drawbacks.
  • the technical problem underlying the invention consists in particular of providing a suction head which is simple in structure, while having increased cleaning performance.
  • the rotating brush has a brush diameter of between 0.03 and 0.08 m, and for example between 0.03 and 0.065 m
  • the rotation drive device is configured to rotate the brush body at a speed of predetermined rotation between 2000 and 8000 rpm, advantageously between 3000 and 5000 rpm and for example equal to approximately 4100 rpm, and a ratio of the offset angle, expressed in degrees, to a tangential speed, expressed in ms -1 , at the level of the free ends of the bristles of the row of bristles when the brush body is rotated at the predetermined rotation speed is between 2.5 and 3.5.
  • the term “brush diameter” means the external diameter of the rotating brush measured at the level of the free ends of the bristles. In other words, the brush diameter corresponds to the diameter of a circle centered on the central longitudinal axis of the brush body and in which the rotating brush is inscribed.
  • the brush diameter is less than 0.08 m. Brush diameters less than 0.03 m do not allow the rotating brush to effectively collect waste lying on the surface to be cleaned. In this document, waste is also referred to as dust particles.
  • rotation speeds of the brush are between 2000 and 8000 rpm to reach tangential speeds at the free ends of the bristles which allow the brush to effectively collect waste resting on the surface to be cleaned and to allow projection of the collected waste towards a rear part of the suction chamber.
  • the present invention makes it possible to position the cleaning blade angularly and optimally in relation to the row of bristles, taking into account the brush diameter and the rotation speed of the brush, and therefore the tangential speed at the ends. free of hair.
  • the present invention therefore allows the cleaning blade to carry, towards the suction mouth and in an efficient manner, dust projected into the air by the scraping action of the row of bristles, and therefore to increase by sensitively the quantity of dust sucked up by the suction head each time the latter passes over a predetermined area of a surface to be cleaned.
  • the offset angle of the cleaning blade relative to the row of bristles is too great in relation to the tangential speed at the free ends of the bristles such that the ratio of the offset angle, expressed in degrees , on speed tangential, expressed in ms -1 , or greater than 3.5 does not allow the cleaning blade to capture sufficient volatile dust projected into the air by the scraping action of the row of bristles. Indeed, in such a configuration, most of the volatile dust falls to the ground before being captured by the cleaning blade.
  • the angle of offset of the cleaning blade relative to the row of bristles is on the contrary too low compared to the tangential speed at the level of the free ends of the bristles such that the ratio of the offset angle, expressed in degree, on the tangential speed, expressed in ms -1 , i.e. less than 2.5 does not allow the cleaning blade to capture sufficient dust thrown into the air by the scraping action of the row of bristles .
  • the cleaning blade is too close to the bristle strip and most of the volatile dust, projected into the air by the scraping action of the row of bristles, is projected behind the cleaning blade. cleaning which therefore does not capture these volatile dusts.
  • the specific positioning of the cleaning blade of the suction head according to the present invention therefore gives the latter increased cleaning performance.
  • the suction head may also have one or more of the following characteristics, taken alone or in combination.
  • the main body comprises a suction conduit opening into the suction chamber, and for example into a rear part of the suction chamber.
  • the cleaning blade is configured to drive dust suspended in the air and located behind the row of bristles towards the suction mouth, and for example to drive said dust towards a rear part of the suction chamber.
  • the brush body has a shape generally tubular.
  • the offset angle is between 20 and 90°, advantageously between 25 and 55°, and for example between 32 and 46°.
  • Such positioning of the cleaning blade further promotes the entrainment of dust particles suspended in the air by the cleaning blade, and therefore gives the cleaning head according to the present invention even increased cleaning performance.
  • the tangential speed at the free ends of the bristles of the row of bristles, when the brush body is rotated at the predetermined rotation speed is between 8 and 26 ms - 1 .
  • Such a tangential speed further promotes the entrainment of dust particles suspended in the air by the cleaning blade, and therefore gives the cleaning head according to the present invention even increased cleaning performance.
  • the row of bristles extends helically around the central longitudinal axis of the brush body, and the cleaning blade extends helically around the central longitudinal axis of the brush body .
  • the row of bristles and the cleaning blade extend, relative to the central longitudinal axis of the brush body, at helix angles which are substantially identical.
  • the row of bristles and the cleaning blade are spaced from each other by a separation distance which is substantially constant along the row of hairs.
  • the cleaning blade is elastically deformable.
  • the cleaning blade could be rigid or semi-rigid.
  • the bristles of the row of bristles protrude from the outer peripheral surface of the brush body by a first projection distance
  • the cleaning blade protrudes from the outer peripheral surface of the body brush of a second projection distance which is less than the first projection distance.

  • the cleaning blade is configured not to interact with a surface to be cleaned when the suction head is moved over said surface to be cleaned.
  • the bristles of the row of bristles are configured to project from the suction mouth.
  • the cleaning blade is configured to be located back from the suction mouth.
