Definitions

  • the present invention relates to a nozzle for a vacuum cleaner, and to a vacuum cleaner having such a nozzle.
  • EP1875846 and WO 2007/031819 disclose prior art nozzles for floor vacuum cleaners.
  • a good vacuum cleaner nozzle must have high cleaning performance, i.e. effective debris pick up, but at the same time be easy to handle and move across a surface to be cleaned, such as a carpet.
  • high cleaning performance is obtained only at the expense of an increased resistance to motion across a surface and so requires an increased application of force by the user to move the nozzle.
  • the nozzle may have unpleasant dynamic behaviour in the sense that it does not move particularly well across a surface when it is pushed and/or pulled.
  • a nozzle for a vacuum cleaner comprising a soleplate with a suction channel slot therein for the suction of debris from a surface, a wheel mounted for rotation about an axis to support the nozzle on said surface, and a suction pipe connector for rotation about an axis that is coaxial with said wheel axis, the wheel having a radius (h) of at least 25mm, and wherein a distance (X) across the surface between a point of contact of the wheel with the surface that is directly beneath the wheel axis and a point midway between the leading and trailing edges of the suction channel slot is no greater than 80mm
  • the nozzle comprises a housing in which the soleplate and suction channel slot are formed, and the wheel and suction pipe connector may be mounted to the housing for rotation about said wheel axis.
  • the nozzle may comprise a housing in which the soleplate and suction channel slot are formed, the wheel and suction pipe connector being mounted for rotation relative to each other about the wheel axis, and the housing being mounted for rotation relative to the wheel and the suction pipe connector about a second axis parallel to and spaced from the first axis.
  • a link arm extends between said wheel axis and the second axis, and is pivotally connected to each of the suction pipe connector and the housing.
  • the ratio of the radius of the wheel (h) to the sum of the distance X across the surface between a point of contact of the wheel with the surface that is directly beneath the wheel axis and a point midway between the leading and trailing edges of the suction channel slot and a distance (1/2 C) across the surface between the point midway between the leading and trailing edges of the suction channel slot and the leading edge of the suction channel slot is greater than 0.3.
  • a vacuum cleaner including a suction pipe and a nozzle according to the invention, the suction pipe being connected to the nozzle via the suction pipe connector.
  • FIG. 1 A cross-sectional side elevation of a conventional nozzle 1 for a vacuum cleaner (not shown) is illustrated in Figures 1 and 2 .
  • the nozzle 1 comprises a main body or housing 2 having an elbow or suction pipe connector 3 attached to a rear end of the housing 2 for rotation relative to the housing 2 about an axis A.
  • a suction pipe 4, which does not form part of the nozzle 1, is attachable to and extends upwardly from the suction pipe connector 3.
  • the suction pipe 4 provides a conduit for the passage of dust and debris that has been sucked from a surface S and having been vacuumed through the nozzle 1.
  • the suction pipe 4 also acts as a handle to enable a user to push the nozzle in a forward F direction and pull it in a rearward R direction during use.
  • a wheel 5 is mounted to the housing 2. It is also mounted to the suction pipe connector 3 for rotation about the same axis A as the suction pipe connector 3 to support and guide the nozzle 1 across the surface S.
  • the underside of the housing 2 is provided with a soleplate 6 which contacts the surface S being vacuumed.
  • An elongate suction channel slot 7 is formed in the soleplate 6 and extends across the width of the housing 2 substantially at right angles to the forward F and rearward R directions of movement.
  • the elongate suction channel slot 7 has parallel leading and trailing edges 7a, 7b that define the edges of the slot 7 in the soleplate 6. It will also be appreciated that the slot 7 may have a different shape.
  • Thread or debris pick-up strips 8 may be provided forwardly of the leading edge 7a and/or rearwardly of the trailing edge 7b to assist in releasing hair or threads from the surface S being vacuumed.
  • the main phenomenon behind dust pickup from a surface S such as a carpet is the opening of the pile.
  • a vertical force has to be applied on the leading edge 7a of the suction slot 7.
  • the only force that is generated in this direction apart from the force generated as a result of the weight of the nozzle 1 itself, is a horizontal friction force that is applied by the user via the suction pipe 4 to push the nozzle 1 across the carpet surface S.
  • distance h is important.
  • Distance h is the distance from the axis of rotation A of the wheel 5 to the surface S, and is equivalent to the radius of the wheel 5. As distance h increases, the higher the downward vertical force V of the suction edge against the pile will be as the vacuum cleaner is pushed in the forward direction F along the surface S by a user who applies a force to the nozzle 1 via the suction pipe 4 in a direction that extends along line P.
  • distance q represents the length of a line that extends from the leading edge 7a of the suction slot 7 and intersects at right-angles with the line P along which the force F is applied to the nozzle 1 which is generated by a user as a result of pulling the suction pipe 4 across the carpet surface S.
  • a moment/torque T is generated (as indicated by arrow T in Figure 2 ) that causes the nozzle to pivot on the carpet surface S about the leading edge 7a of the suction slot 7 that results in the nozzle 1 tilting and the wheel 5 lifting off the ground (as shown by dotted lines indicated as 5a in Figure 2 ) until the torque T is at zero, which occurs when the the leading edge 7a and the wheel axis A both lie on the same line as the applied force P.
  • this tilting action is undesirable because the trailing edge 7b of the suction slot 7 is no longer in contact with the carpet surface S, and so air will start seeping in through a bypass path, rather than through the carpet, and so this is undesirable and results in a reduction in suction performance.
  • the tilting action also causes unpleasant bouncing, irregular movements of the nozzle 1.
  • the distance q should be maintained as small as possible in order to minimise the undesirable tilting action explained in more detail above.
  • the distance h needs to be selected so as to maintain a vertical force V which will maintain the suction slot 7 against the pile when the nozzle 1 is pushed in a forward direction F.
  • the inventors have determined that to balance the requirement of preventing loss of suction when the nozzle 1 is pushed in the forward direction F, and the requirement to minimise or alleviate bouncing and irregular movement of the nozzle 1 (by maintaining a low distance q and keeping the aforementioned torque T at a minimum) when the nozzle 1 is pulled in the rearward direction R, a certain combination of wheel diameter h and the distance of the wheel to the centre of the suction channel 7 is important. By selecting these parameters carefully, it has been found that a good balance between effective dust pick up and the force required by a user to move the nozzle 1 easity when it is pushed in the forward F direction and also when it is being pulled in the rearward direction R is achieved.
  • the dimension q should be smaller than 24 mm to provide the best possible performance of the nozzle 1 when it is being pulled in the rearward direction R.
  • the distance q is related to the distance of the wheel axle A above the surface S (i.e. dimension h referred to above, which is equivalent to the radius of the wheel 5), and the dimension X (see Figure 3 ), which is the distance across the surface S between the point of contact Y of the wheel 5 with the surface S directly below the axis A, and a centre line M (see Figure 3 ) midway between the leading and trailing edges 7a, 7b of the suction channel slot 7, i.e. an imaginary centre line that is parallel to and equidistant from both the leading and the trailing edges 7a, 7b of the suction channel slot 7.
  • the centre line M is positioned at 1/2C from the leading and trailing edges 7a, 7b.
  • the suction channel slot 7 is ideally rectangular in shape, and extends across the width of the nozzle 1 in a direction at right angles to the forward F and backward R direction of movement of the nozzle 1, and parallel to the wheel axis A.
  • the suction channel slot may be shaped or extend at an angle in some way, in which case the measurement X referred to above should be taken from at a central point, midway between each end of the slot 7 in a direction across the width of the nozzle 1.
  • this formula is derived assuming the suction slot width C as 20mm.
  • the slot width C is in the region of 18 to 21mm.
  • the ratio is less than 0.3, the force required to push the nozzle in the forward direction F is smaller, as would be the vertical force V acting on the leading edge 7a of the nozzle 1. Consequently, the dust pickup efficiency would reduce.
  • a ratio of less than 0.3 results in a larger value for distance q, and so the torque required to cause the nozzle 1 to tilt increases when the nozzle 1 is being pulled in the rearward direction R.
  • the specified parameters are chosen so as to provide a ratio of greater than 0.3, the vertical force V on the leading edge 7a of the nozzle 1 for a given force applied by the user to push the nozzle 1 forward is higher than whenever parameters are chosen which are smaller then the specified ratio.
  • distance q will be resulting in less torque T on the nozzle for the same friction force than whenever a setting is chosen outside the specified ratio.
  • the nozzle 1 for a vacuum cleaner comprising the housing 2 having the soleplate 6 with the suction channel slot 7 therein for the suction of debris from the surface S, the wheel 5 mounted to the housing 2 for rotation about the axis 1 that extends substantially parallel to the leading and trailing edges 7a, 7b of said suction channel slot 7 to support the nozzle 1 on said surface S, and the suction pipe connector 3 mounted to the housing 2 for rotation about an axis that is coaxial with said wheel axis A.
  • the ratio of the radius h of the wheel 5 to the distance X across a surface, between the point of contact Y of the wheel 5 with the surface S that is directly beneath the wheel axis 1, and the point midway between the leading and trailing edges 7a, 7b of the suction channel slot 7 is greater than 0.3.
  • the parameters are selected so as to provide a ratio of greater than 0.3 when the width C of the suction slot 7 lies in the range of 18 to 21mm.
  • FIG 4 The embodiment shown in Figure 4 is the same as that shown in Figure 3 , except that the wheel 5 is pivotally mounted to the suction pipe connector 3, d the housing 2 is pivotally mounted to the suction pipe connector 3 for rotation about a second axis B which is spaced from the wheel axis A.
  • a link arm 10 extends between the axes A and B, and connects the housing 2 to the suction pipe connector 3. It will be appreciated that, in this embodiment, the housing 2 can pivot about axis B independently to movement of the suction pipe connector 3 and the wheel 5 about axis A, and so the housing 2 can assume a different angle during the forward F and backward R strokes.
  • Figure 5 is a table that provides a number of ratios obtained from the equation identified above with different vacuum cleaner nozzles 1 having differing values for distance X, wheel radius h and slot width C. It also demonstrates how dust pick up efficiency and motion resistance is optimised when the calculated ratio is greater than 0.3 "Nozzle 1" represents the nozzle according to the invention, whereas "nozzles 2, 3 and 4" represent those of the prior art. Although this table represents values obtained from a nozzle 1 having a double hinge arrangement, as described with reference to Figure 4 , similar advantages are obtained with the nozzle 1 described with reference to Figure 3 in which there is only one pivot point.
