Definitions

  • the invention relates to a side brush for a vacuum cleaner (vacuum cleaner side brush) or for any other floor care device, in particular a side brush for an autonomous, self-propelled vacuum cleaner system (suction robot; Robotsauger).
  • Floor care appliances such as vacuum cleaners, upright vacuum cleaners or vacuum robots, have certain characteristics in a contact zone with the surface to be cleaned in order to detect and transport the mostly solid dust and dirt particles using certain physical principles.
  • An important principle is the impulsive solid contact between Bürstfilêtn and the respective processed substrate and the dirt particles located there. In this way, said dirt particles are mobilized and transported.
  • Such side brushes are known, for example from the EP 2 606 798 A2 .
  • Known side brushes have a few, evenly spaced brush arms in the form of brushes, ie bristle tufts or sleeves with bristles tufts fixed therein.
  • the known side brushes have two, three, four or five such brush arms, at least a few brush arms on.
  • a side brush in particular a side brush with a better surface coverage
  • a floor care appliance in particular a floor care appliance in the form of a vacuum robot, with at least one such side brush.
  • a side brush and a floor care device having the features of claim 1 and the features of the further independent device claim.
  • a side brush for a floor care device in particular a vacuum cleaner or a vacuum cleaner in the form of a Saugroboters, provided the following:
  • the side brush has a brush core and regularly distributed over a peripheral surface of the brush core bristle tufts and compared to previous side brushes increased number of bristle tufts, So for example at least ten bristle tufts.
  • a ground care device proposed here for example a floor care device in the form of a vacuum cleaner or vacuum robot, is characterized in that it has at least one such side brush or a side brush at the positions usual for a side brush, in each case at least one such side brush two side brushes, has.
  • the desired better surface coverage results because each end of a bristle tuft sweeps over the respective processed substrate and accordingly in the proposed here increased number of bristle tufts when crossing a respective processed Subsoil resulting over strokes of the individual bristle tufts are closer together than can be the case with previous side brushes with the usual three, four or a maximum of five bristle tufts.
  • the rotational speed of the side brush can be reduced without deteriorating the area coverage and the cleaning result. A reduced rotational speed leads advantageously to a reduced noise and reduced wear.
  • the bristle tufts are arranged in at least two parallel planes (insertion planes) on the brush core, with a plurality of bristle tufts in each insertion plane, in particular such that the same number of bristle tufts or at least substantially the same in each insertion plane Number of bristle tufts is located.
  • a plurality of parallel insertion planes ie at least two parallel insertion planes, allows in a particularly favorable manner for improving the area coverage desired increase in the number of bristle tufts, without compromising the stability of the brush core in question or perform this unfavorably large to improve the stability to have to.
  • the bristle tufts are attached to the brush core and aligned so that the tips of all bristle tufts of each of the at least two planes lie on a common envelope circle or at least substantially on a common envelope circle.
  • peaks of the bristle tufts sweep in a standing floor care device all tips the same place.
  • the resulting overstresses are located particularly close to each other over the respective processed substrate, resulting in optimum area coverage.
  • Yet another embodiment of the side brush is characterized by an alternating arrangement of the bristle tufts in the at least two insertion planes.
  • the alternating arrangement refers to the order of the ends of the bristle tufts along the common envelope circle.
  • a bristle tuft belonging to any local end of a bristle tuft (first tuft) is followed in the direction of rotation by the end of a bristle tuft (second tuft) which is fixed to the brush core in a different insertion plane from the first tuft.
  • the end of the second tuft is followed by the end of another tuft of bristles (third tuft), the bristle tufts in a different insertion plane on the brush core compared to the insertion plane of the second tuft is fixed, for example, in the mating plane of the first tuft.
  • This alternating arrangement allows a regular distribution of the ends of the bristle tufts along the common enveloping circle and thus also ensures optimum area coverage.
  • each sleeve is aligned approximately tangential to the peripheral surface of the brush core.
  • This tangential orientation of each sleeve causes each brush tuft is also aligned tangentially or at least substantially tangential to the peripheral surface of the brush core.
  • a tuft of bristles tipping perpendicularly to an obstacle may adversely affect the maneuverability of a floor care implement having such a tuft of bristles.
  • the portion of a tuft of bristles fixed there can be located at an insertion depth in the sleeve which extends beyond the radius of the brush core.
  • a comparably secure fixation of the bristle tufts in a radially oriented sleeve can only be achieved with a considerably larger brush core, namely a brush core with a larger diameter.
  • the approximately tangential orientation of the sleeves thus also avoids that the brush core must be made unnecessarily large.
  • FIG. 1 shows an embodiment of a side brush 10 proposed here for a self-shown floor care device, for example a floor care device in the form of a vacuum cleaner, in particular in the form of a vacuum robot.
  • the side brush 10 comprises a plurality of bristle tufts 12, in the illustrated embodiment exactly twenty bristle tufts 12.
  • the brush filaments comprised of the brush tufts 12 are not shown separately and the cylindrical shape shown is intended to represent the entirety of the respective brush filaments.
  • All bristle tufts 12 are fixed to a brush core 14 (brush body) of the side brush 10 and the brush core 14 defines an axis of rotation of the side brush 10 and includes in the embodiment shown a recess / bore for positive reception of a rotationally driven in the usual way or the like.
  • Each bristle tufts 12 - or a brush arm with a bristle tufts at the free end instead of the bristle tufts 12 shown - is fixed to the brush core 14 in each case here and hereinafter referred to collectively as sleeve 16 designated sleeve or bore.
  • a bore for receiving a portion of a respective bristle tufts 12 is inserted into the solid material of the brush core 14.
  • a sleeve 16 may be formed on the brush core 14, in particular integrally connected to the brush core 14, or glued to the brush core 14 or connected in any other suitable manner.
  • FIG. 2 shows a part of a side brush 10 according to FIG. 1 in a side view. Shown are two pairs of sleeves 16 located in different insertion planes illustrated by the lateral horizontal arrows and the bristle tufts 12 fixed there.
  • FIG. 3 shows the side brush 10 according to FIG. 1 in a view from above. Particularly well recognizable there is especially that the ends of all bristle tufts 12 on a common envelope circle 20 ( Fig. 4 ) or at least substantially on a common enveloping line 20 and regardless of which plane of the bristle tufts 12 are fixed to the brush core 14. Furthermore, the alternating arrangement of the bristle tufts 12 in the insertion planes described at the outset and related to the order of the ends of the bristle tufts 12 along the enveloping circle line 20 can also be seen.
  • the enveloping line 20 is shown separately in FIG FIG. 4 shown.
  • FIG. 4 and FIG. 5 illustrate individual geometrical relationships of the side brush 10 described below.
  • the diameter of the enveloping circle defined by the enveloping circle line 20 is denoted by d ( Fig. 3 . Fig. 5 ) and is for example 120 mm, with other preferred dimensions of the side brush 10 resulting in diameters ranging from about 100 mm to 140/150 mm.
  • First and second diameters of the brush core 14 are in FIG. 4 and FIG. 5 denoted by e and f.
  • the first, larger diameter e results in the region of the upper insertion plane of the brush core 14 and the second diameter correspondingly in the region of the lower insertion plane.
  • the first diameter e is 30 mm ( ⁇ 10 mm) and the second diameter f is 25 mm ( ⁇ 10 mm).
  • the lower and upper insertion planes on the brush core 14 in the illustrated embodiment are approximately 11 mm ( h ) or approximately 15 mm ( j ) above the enveloping circle common to all bristle tufts (FIG. Fig. 5 ).
  • an angle ⁇ between the central axis a and the bristle tuft 12 emanating from the plug-in point p1 is approximately 50 ° ( ⁇ 10 °), in the exemplary embodiment shown 51 °.
