Definitions

  • the invention relates to a brush suction nozzle provided with impellers, which has a height-adjustable, rotatable brush roller which is arranged in a roller chamber in the mouthpiece housing and which, with its bristles in the working position, reaches through a suction slot provided in the base plate of the roller chamber and is driven by a drive unit arranged in the mouthpiece housing.
  • Such a brush suction mouthpiece is known from DE-A-2 057 466.
  • the use of such mouthpieces is practically only possible on textile floor surfaces.
  • the floor slab with the suction slot must be lifted off the floor surface to avoid scratching both the floor covering and the floor slab.
  • the base plate is arranged higher than the bearing surface of the impellers.
  • the cleaning effect of the mouthpiece on hard floors is considerably impaired, since the flow velocity of the suction air below the base plate decreases considerably as a result of the distance between the base plate.
  • the rotating brush roller also interferes. If the drive of the brush roller were stopped, the stationary brush roller partially blocked the suction slot and further reduced the suction power of the mouthpiece. In addition, a large proportion of the dirt that is sucked up settles on the brush roller.
  • the invention has for its object to provide a brush suction mouthpiece of the type described in such a way that a good cleaning result can be achieved with such a mouthpiece even on hard floors without the risk of contamination of the brush roller.
  • the object is achieved according to the invention in that in the area in which the base plate merges into the mouthpiece housing or is connected to it, an elastic sleeve extending over the full width of the mouthpiece is arranged on each side of the suction slot, wherein both sleeves extend to the support level or just up to the support level of the impellers that the brush roller is adjustable in height so far that its bristles no longer touch the surface to be extracted, and can be locked in this position.
  • the sleeves create a largely closed space under the suction slot and the inflow of the suction air is concentrated on the slots existing between the edges of the sleeve and the surface to be extracted.
  • the suction air reaches high speeds here and is therefore able to carry more dirt with it.
  • the hard floor is no longer touched by the raised brush roller, so that the dirt is no longer thrown away from the brush roller. Wear of the brush roller is also avoided.
  • Dirt pick-up in the immediate vicinity of the walls delimiting the floor to be suctioned off is achieved in that a continuous front suction slot or several front suction openings are provided in the base plate immediately after the front sleeve.
  • a braking device which brakes the rotation of the brush roller in its uppermost position is arranged in the roller chamber.
  • a particularly simple construction of the braking device consists of a bar arranged in the roller chamber, on which the brush roller brushes with its bristles in its uppermost position. The brush roller is braked in the same way as when brushing the bristles over the floor surface to be cleaned.
  • a reduction in the sliding resistance is achieved in that at least the sleeve arranged on the front side wall of the roller chamber is fastened to the side wall only in the region of its upper edge and lies loosely against the side wall in the region from the fastening point to the end of the side wall.
  • the brush roller 7 is, as indicated by an arrow 10, arranged in the roller chamber 6 to be adjustable in height.
  • the adjustment mechanism required for this is not shown in the drawing.
  • the height adjustment can be carried out, for example, by means of a pivotally mounted rocker arm, with one end of which the axis of rotation of the brush roller is connected and the other end of which is coupled to an operating element which is adjustable from outside the housing.
  • the brush roller 7 in the roller chamber 6 can be adjusted upwards to such an extent that its bristles no longer come out of that in the base plate 11 Step out of the roller chamber 6 provided suction slot 12.
  • a bar 13 is arranged which is dimensioned such that the brush roller 7 brushes the bar 13 in its upper position with its bristles. The brush roller 7 can be locked in the upper position.
  • the cuffs 16 and 17 can be designed as a one-piece strip made of rubber, plastic, non-woven material or the like, but also as a tight brush strip.
  • the cuff 16 arranged on the front side wall 14 of the roller chamber 6 is fastened to the side wall 14 relatively high up. In the lower area, the cuff 16 lies only on the side wall 14.
  • a front suction slot 18 is provided in the base plate 11 of the roller chamber 6 immediately after the front side wall 14. Instead of such a front suction slot 18, a plurality of front suction openings arranged in a row can also be provided.
  • the front suction slot 18 results in a stronger suction air flow directly behind the sleeve 16 fastened to the front side wall 14, through which the dirt is absorbed in the front area of the base plate 11. This achieves a good cleaning effect right up to the boundary walls of the surface to be extracted.
  • the brush roller 7 can be brought into its upper position when vacuuming on hard floor, so that its bristles no longer touch the floor and can thus throw away the dirt stored on the floor. If the brush roller 7 is driven by a turbine actuated by the suction air, then it is advantageous that its rotational movement is braked in the upper position in order to avoid an increase in the speed of the practically idling turbine associated with a corresponding noise development.
  • the strip 13 is provided on the ceiling of the roller chamber 6, on which the brush roller 7 brushes with its bristles and is thereby braked as when the carpet pile is slipped on. By lifting the brush roller 7, the suction slot 12 is released so that the suction air can flow through unhindered. The fact that the brush roller 7 continues to rotate in the upper position prevents dirt from being deposited thereon.
