Definitions

  • the present invention relates to a brush assembly for a floor cleaning apparatus, such as a vacuum cleaner or sweeper.
  • a floor cleaning apparatus comprising one or more brush assemblies which rotate on movement of the floor cleaning apparatus to agitate dust and contaminants on a surface on which the floor cleaning apparatus is disposed.
  • Beater bars are known for use on many types of vacuum cleaners, particularly upright vacuum cleaners in which a suction head is moved around the floor by a user pushing and pulling an upright handle.
  • Such beater bars are generally driven by a drive belt powered by a motor.
  • the bar is usually cylindrical and has tufts of bristles disposed around its outer circumference which contact the floor as the bar rotates.
  • the axis of rotation of the cylindrical bar is usually parallel to the surface to be cleaned. This agitates dust and other contaminants to increase the likelihood that they are sucked into the suction inlet of the vacuum cleaner.
  • EP2561785 discloses a different type of auxiliary beater brush assembly for an upright vacuum cleaner.
  • the auxiliary brushes comprise tufts of bristles mounted around the circumference of a circular body, two of which are rotatably mounted on brackets projecting from the sides of the suction head.
  • the brackets are angled downwardly such that the outermost edges of the auxiliary brushes are in contact with the floor. Pushing and pulling the suction head rotates the brushes to agitate the surface on which the vacuum cleaner is disposed.
  • a brush assembly for a floor cleaning apparatus comprising: a body portion rotatably mountable to an underside of a floor cleaning apparatus; a plurality of bristles disposed around the edge of the body portion, said plurality of bristles being configured to engage a surface to be cleaned; and a plurality of floor engaging members projecting from the underside of the body portion, each said floor engaging member being capable of frictionally engaging the surface on which the brush assembly is disposed to cause rotation of the body portion as the brush assembly is moved along said surface.
  • This provides the advantage of a brush assembly for a floor cleaning apparatus that has been found to reliably rotate on both carpets of all thicknesses and uncarpeted surfaces.
  • This provides the advantage of improving grip and ensuring reliable rotation when the vacuum cleaner is moved.
  • each said floor engaging member comprises an elastomeric finger.
  • the elastomeric fingers may be flexible. This allows the fingers to grip a range of surfaces including wooden or tiled surfaces without damaging the surface.
  • a longitudinal axis of each said engaging member is non-perpendicular to the underside of said body portion.
  • the brush assembly further comprises bearing means arranged to allow rotation of said at least one brush assembly in a first direction, but prevent rotation of said at least one brush assembly in a second direction, opposite to said first direction.
  • the axis of rotation of the body portion may be non-parallel to said surface.
  • a vacuum cleaner comprising: a handle portion; a collection apparatus for removing contaminants from an airstream; a base portion configured to be moved along a surface to collect contaminants therefrom, the base portion comprising a suction inlet; and at least one brush assembly as defined above rotatably mounted to the underside of said base portion.
  • the axis of rotation of said at least one brush assembly is arranged such that a first side of said at least one brush assembly closest to said suction inlet is tilted towards a surface on which the vacuum cleaner is disposed and a second side of said at least one brush assembly, opposite said first side, is tilted away from said surface.
  • the vacuum cleaner may further comprise first and second brush assemblies rotatably mounted to the underside of said base portion, wherein the axis of rotation of each said brush assembly is arranged such that a first side of each said brush assembly closest to said suction inlet is tilted towards a surface on which the vacuum cleaner is disposed and a second side of each said brush assembly, opposite said first side, is tilted away from said surface.
  • the following describes a vacuum cleaner with a brush assembly for agitating dirt and other contaminants on a surface to be cleaned.
  • the brush assembly can be implemented on other types of floor cleaning apparatuses, such as a sweeper or a steam mop.
  • a vacuum cleaner 2 comprises a handle portion (not shown) and a housing 4 containing a collection apparatus for removing contaminants from an airstream.
  • a collection apparatus for removing contaminants from an airstream.
  • Types of collection apparatus will be familiar to persons skilled in the art.
  • the collection apparatus for separating contaminants from the airstream could take the form of a cyclone separator, a filter bag, or a combination of cyclone separator and filter arrangements.
  • Vacuum cleaner 2 also comprises a base portion 6 having a suction inlet 8 arranged to draw air into the base portion 6 on operation of the motor (not shown) of the vacuum cleaner 2.
  • At least one, and preferably two brush assemblies 10 are rotatably mounted to the underside of base portion 6.
  • Each brush assembly 10 comprises a body portion 12 around the circumference of which a plurality of bristles 14, preferably clumped in bristle tufts are mounted.
  • each floor engaging member 16 On the underside of each body portion 12, a plurality of floor engaging members 16 are disposed. Eight floor engaging members are shown spaced equiangularly from the centre of the body portion 12, although more or less floor engaging members could be used depending on the size of the body portion 12.
  • Floor engaging members 16 are configured to engage a surface on which the vacuum cleaner 2 is placed such that when the vacuum cleaner is advanced forward, the floor engaging members 16 grip the surface to cause rotation of the body portion 12 and therefore brush assemblies 10.
  • each floor engaging member comprises a finger.
  • each finger could be made from rubber or another elastomeric polymer or another suitable material such as a plastic.
  • each brush assembly 10 (shown without bristles for clarity) comprises a shaft 18 keyed to the body portion 12 to enable the body portion 12 to be rotatably mounted to the base portion 6 of the vacuum cleaner 2.
  • Shaft 18 is disposed non-rotatably in one-way bearing 20 which permits rotation in only one direction as will be further explained below.
  • the axis of rotation R is offset from the vertical Y by an angle ⁇ such that a first side 10a of the brush assembly closest to suction inlet 8 is tilted towards a surface S on which the vacuum cleaner is disposed.
  • angle ⁇ is between 2 and 10 degrees and, more preferably, between 3 and 6 degrees. In particular, an angle between 4 and 5 degrees has been found to be optimal for providing a large contact zone for the brush and the rubber fingers, as shown in figure 10 .
  • each elastomeric finger 16 is mounted non-perpendicularly to a plane P defined by body portion 12. This ensures that the ends of elastomeric fingers 16 make the best contact with surface S.
  • each finger 16 could be mounted perpendicularly to plane P for ease of manufacture.
  • both brush assemblies 10 are mounted on axes of rotation that are non-parallel to the vertical axis of body portion 6 such that sides 10a of the brush assemblies 10 closest to suction inlet 8 are tilted towards surface S. Also, the axes of rotation of the brush assemblies are non-parallel to the surface S and to the horizontal axis of the body 6.
  • shaft 18 and one-way bearing 20 are also arranged such that the part of each brush assembly 10 forward of the shaft 18 is tilted towards the surface S. This is achieved by tilting the axis of rotation of the brush assembly, which runs longitudinally along the shaft 18, forwardly and towards the front edge 6a. As shown, the part projecting forwardly of the front edge 6a of base portion 6 is tilted towards the surface S on which the vacuum cleaner 2 is disposed.
  • an angle ⁇ is formed between a horizontal axis X of the body portion and the plane of rotation of the brush assembly 10.
  • angle ⁇ is between 1 and 4 degrees and, more preferably between 2 and 3 degrees. This provides an optimal contact area forward of the front edge whilst preventing the brush from digging too deep into carpet when the vacuum cleaner is pushed forwardly.
  • each brush assembly 10 When the base portion 6 is pulled rearwardly in the direction of arrow B of Figure 4 , the one-way bearing 20 of each brush assembly 10 prevents rotation which therefore prevents dust being flicked away from the suction inlet 8. On further advancement of the vacuum cleaner 2 in the direction of arrow A, brush assemblies 10 will continue to rotate.
  • projecting fingers 16 are effective on various thicknesses of carpet as well as hard floors to provide improved drive of the brush assemblies 10 when compared with use of a continuous ring of frictionally engaging material. Improved cleaning has also been found resulting from prevention of rotation of the brush assemblies on a rearward stroke.
