Definitions

  • This invention relates to a surface cleaning apparatus.
  • this invention relates to a surface cleaning apparatus which utilises a source of suction to draw dirt etc. from a surface being cleaned and to store said dirt in a chamber which can be emptied by a user.
  • Such surface cleaning apparatus are often referred to a "vacuum cleaners”.
  • a surface cleaning apparatus having:
  • first wheel preferably the first wheel being positioned at or near a first end of the main body
  • a second wheel preferably the second wheel being positioned at or near a second end of the main body
  • a primary air inlet preferably wherein said air inlet is positioned substantially midway between the first and second wheels
  • the apparatus includes a rotatable member positioned adjacent or near the primary air inlet.
  • Figure 1 is a perspective view of a first embodiment of an apparatus according to the invention
  • Figure 2 is a plan view of the apparatus of figure 1
  • Figure 3 is a side view of the apparatus of figure 1
  • Figure 4 is an end view of the apparatus of figure 1 ;
  • Figure 5 is a further plan view of the apparatus of figure 1 ; and Figure 6 is a yet further plan view of the apparatus of figure 1 .
  • FIG 1 this shows a surface cleaning apparatus 10 in accordance with the present invention.
  • the apparatus includes a main body 12 which in this particular example (as can be seen from the figures), is generally cylindrical.
  • the apparatus 10 has a pair of wheels 14, 16.
  • the first wheel 14 is positioned at or near the first end of the main body 12, whilst the second wheel 16 is positioned at or near the second, opposite, end of the main body 12.
  • the first and second wheels 14, 16 each include an annular member which is supported for rotation by an exterior surface of a part of the main body.
  • the main body is generally symmetrical, about a plane which extends midway between the first and second wheels 14, 16, perpendicular to their common rotational axis A.
  • the apparatus 10 includes a primary air inlet 18 which in this example is positioned substantially midway between the first and second wheels 14, 16.
  • the primary air inlet 18 is positioned such that it extends generally upwardly away from a floor surface F supporting the wheels 14, 16.
  • the primary air inlet 18 is connectable to a hose/wand (50) or the like for drawing dirt off of a floor surface.
  • the primary air inlet 18 communicates with a separation device positioned within the main body 12.
  • the apparatus includes a cyclonic separation device.
  • first and second cyclonic separator devices are used which are provided in series in fluid communication with each other.
  • the apparatus 10 includes a suction motor positioned within the main body 12 which draws dirt entraining air through the primary air inlet and into the separation device.
  • a filter bag or the like could be used to collect dirt separated from the air flow.
  • the apparatus includes a dirt collection chamber for collecting separated dirt, which can be emptied as desired.
  • the main body 12 is generally elongate and has an elongate axis which is coaxial with the rotational axis A of the wheels 14, 16.
  • the axis A of the main body extends lengthwise of the apparatus between the wheels 14, 16.
  • the apparatus 10 in accordance with the present invention includes a pair of rotatable members 20a, 20b which are positioned adjacent / near the primary air inlet 18.
  • two rotatable members are provided. It should be appreciated, however, that embodiments are envisaged where only one (or more than two) of the rotatable members 20a, 20b is provided.
  • the rotatable members 20a, 20b are positioned adjacent/near either side of the primary air inlet 18 and are connected to an upwardly facing exterior surface of the main body 18.
  • the rotatable member 20a, 20b are positioned transversely either side of the inlet 18 relative to the axis A.
  • the rotatable members 20a, 20b are rotatable about axes B which are substantially parallel with each other.
  • the axes B are also substantially parallel with the rotational axis A of the first and second wheels 14, 16.
  • the rotational axes B of the rotatable members 20a, 20b are substantially parallel with the elongate axis of the apparatus and the elongate axis of the main body 12.
  • Each rotatable member 20a, 20b is supported by a support frame 23 which includes a pair of radially extending (relative to axis A) support member 21 a, 22a which are substantially triangular in side view (see figure 4).
  • the support members 21 a, 22a each include an aperture 24 through which an axle (not shown) is passed to support rotation of the rotatable member 20a, 20b.
  • the first rotatable member 20a limits the amount of rotation of the main body 12 about the axis A and in first rotational direction R-i .
  • the second rotatable member 20b limits the amount of rotation of the main body 12 about the axis A in a second, opposite, rotational direction R 2 (see figure 6).
  • the first and second rotatable members 20a, 20b prevent the primary air inlet 18 from touching the ground surface F when the first and second wheels 14, 16 are both engaged with the ground surface F. This ensures that the primary air inlet 18 and any connecting end of a wand/hose connected thereto, is prevented from being damaged, upon engagement with a ground surface F, during use.
  • This advantage is achieved not only by the positioning of the rotatable members 20a, 20b either side of the primary air inlet 18 (and close thereto), but also by virtue of the fact that the rotatable members, preferably their axes B of rotation are positioned further from the ground surface F than the rotational axis of the first and second wheels 14, 16, when the primary air inlet 18 is positioned in a neutral condition, pointing substantially upwardly.
  • first and second rotatable members 20a, 20b are barrel-shaped (see figures 2 and 3), they could be provided as other shapes. For example they could be cylindrical, part-cylindrical or spherical. Indeed, embodiments are envisaged where two or more rotatable members are provided at each side of the primary air inlet.
  • the apparatus includes first and second wheels, it should be appreciated that embodiments are envisaged having three or more wheels which are positioned for rotation about respective axes (which could be a common axis). Furthermore, whilst in the present embodiment the first and second wheels 14, 16 have annular members which are rotatable about respective exterior surfaces of the main body 12, this need not be the case. For example, the first and second wheels 14, 16 could take the form of separate wheel members which are connectable by way of suitable axles to the main body 12.
