Definitions

  • the present invention generally relates to the field of nozzles for vacuum cleaners.
  • the present invention relates to nozzles with a retractable brush.
  • nozzles for vacuum cleaners normally comprise a brush, which is retractable into a nozzle head of the nozzle so as to adapt the nozzle to different surfaces to be cleaned.
  • the brush When the brush is retracted, the nozzle is adapted to carpets and when the brush is projected, the nozzle is adapted to hard floors.
  • Efforts have been made to make nozzles adaptable to multiple kinds of surfaces to be cleaned.
  • US 3821831 shows a nozzle with a brush, which is adjustable to three separate positions for cleaning of high pile carpets, bare floors and low pile carpets respectively.
  • a drawback with such a nozzle is that, in the hard floor setting when the brush is projected, dirt tends to be swept in front of the brush instead of passing the brush to be picked up by the suction port of the nozzle.
  • the brush can be provided with cutouts forming gaps between the floor and portions of the brush.
  • cutouts impair the suction power of the nozzle, whereby the performance for cleaning e.g. crevices, or other surface structures requiring a concentrated suction force, is impaired.
  • EP 2 098 150 A2 shows a nozzle according to the preamble of independent claim 1 with brushes that are adjustable in different positions by a lever.
  • the nozzle also have a support which is adjustable by a separate manual actuating device.
  • a drawback with such a nozzle is that it is cumbersam and difficult for the user to understand how to use the different adjustments available.
  • BE 523 546 A shows a nozzle with brushes that are adjustable in different positions through a first mechanism, and supports that are adjustable though a second mechanism.
  • a drawback with such a nozzle is that it is cumbersam and difficult for the user to understand how to use the adjustments.
  • a nozzle having the features defined in the independent claim is provided.
  • Preferable embodiments are defined in the dependent claims.
  • a nozzle for a vacuum cleaner comprises a nozzle head, at least one brush retractable into the nozzle head, and at least one support means arranged to support the nozzle head on a surface to be cleaned and being retractable into the nozzle head.
  • the nozzle further comprises a mechanism arranged to set the brush and the support means in: a first setting, in which the brush and the support means are fully retracted in the nozzle head, a second setting, in which at least a portion of the brush is partly retracted in the nozzle head and the support means is projected further out from the nozzle head than said portion of the brush so as to form a gap between said portion of the brush and the surface to be cleaned, and a third setting, in which the brush is fully projected.
  • the underside of the nozzle head may glide directly on the surface to be cleaned, which facilitates cleaning of soft surfaces, such as carpets.
  • the brush and the support means may not get entangled (or stuck) in the carpet and the distance from a suction port of the nozzle head and the carpet is reduced (or even zero), whereby the suction force is more concentrated, which improves the carpet cleaning performance of the nozzle.
  • Using the first setting on hard floors may imply a risk of scratching the floor.
  • the nozzle is adapted to cleaning of hard floors with crevices or the like features requiring a more concentrated suction force.
  • the brush is fully projected, only a small, or even no gap between the brush and the surface to be cleaned is provided, which makes the suction force of the nozzle more concentrated, whereby the dust pick up of the nozzle is improved.
  • the risk of the nozzle scratching the floor is reduced.
  • Using the third setting on flat hard floor may cause dirt to be swept in front of the brush instead of passing the brush to be picked up by the nozzle at the suction port.
  • the gap between the portion of the brush being partly retracted and the surface to be cleaned allows dust to pass under the portion of the brush being partly retracted to be picked up by the suction port of the nozzle head instead of being swept in front of the brush.
  • the suction force of the nozzle is more concentrated compared to if the brush would be fully retracted.
  • moving the nozzle over carpets is facilitated as at least a portion of brush is not completely projected, thereby reducing the risk of the brush getting stuck on the carpet.
  • the second setting provides an all-around setting, which may be used on various surfaces, whereby the nozzle is more user friendly.
  • the three settings of the nozzle according to the present aspect increase the adaptability of the nozzle to different surfaces, thereby improving the cleaning performance on each surface, and/or make the nozzle more user friendly.
  • the portion of the brush being "fully retracted” may mean that most, or even all, of the brush is retracted into the nozzle head so as to allow the underside of the nozzle head to rest on the surface to be cleaned.
  • the brush being "fully projected” may mean that it is at least more projected than when it is partly retracted, and preferably that it is projected such that no, or just a small (such as less than 1 mm) gap is provided between the brush and the surface to be cleaned.
  • the portion of the brush being partly retracted in the second setting may include at least a front portion and/or at least a rear portion of the brush.
  • the front and/or rear portions of the brush may be slightly raised over the surface to be cleaned in the second setting, thereby allowing dust do pass the brush during the frontward and/or backward stroke, respectively, of the nozzle during vacuum cleaning.
  • the front portion of the brush means the portion of the brush facing in a forward direction when the nozzle is moved away from the user (during the forward stroke). Consequently, the rear portion of the brush is the portion of the brush facing backwards when the nozzle is moved away from the user.
  • the support means may be arranged to support at least a front portion and/or at least a rear portion of the nozzle head on the surface to be cleaned in the second setting.
  • the rear portion of the brush may be arranged to support the rear portion of the nozzle head (e.g. by being fully projected) and the front portion of the brush may be partly retracted so as to allow dirt to pass under the front portion of the brush during the forward stroke of the nozzle.
  • the front portion of the brush may be arranged to support the front portion of the nozzle head (e.g.
  • both of the front and rear portions of the nozzle head being supported by the support means, both of the front and rear portions of the brush (or even the entire brush) may be partly retracted so as to allow dirt to pass under the brush during both the forward and backward strokes of the nozzle, whereby the cleaning performance of the nozzle is improved. Further, the risk of the brush getting stuck on a carpet is further reduced.
  • the front portion of the nozzle head is the portion of the nozzle head facing in a forward direction when the nozzle is moved away from the user (during the forward stroke). Consequently, the rear portion of the nozzle head is the portion of the nozzle head facing backwards when the nozzle is moved away from the user.
  • the portion of the brush may be a first portion, and wherein, in the second setting, a second portion of the brush may be fully projected so as to support at least a portion of the nozzle head on the surface to be cleaned.
  • the at least one support means may comprise at least one wheel (which also may be referred to as a roller), which reduces the risk of the support means scratching the surface to be cleaned.
  • the support means may comprise at least one sliding surface adapted to slide on the surface to be cleaned.
  • the at least one support means may be formed by at least two wheels arranged to support a front portion of the nozzle head or a rear portion of the nozzle head on the surface to be cleaned in the second setting.
  • the portion of the nozzle head not being supported by the wheels may be supported by a portion of the brush.
  • the at least one support means may be formed by at least four wheels arranged to support a front portion of the nozzle head and a rear portion of the nozzle head on the surface to be cleaned in the second setting.
  • one wheel may be arranged at each corner of the nozzle head.
  • the present embodiment allows having the entire brush (or at least the front and rear portions of the brush) partly retracted in the second setting, which is advantageous in that dust may pass under the brush during both the forward and the backward stroke of the nozzle, thereby improving the cleaning performance of the nozzle. Further, the risk of the brush getting stuck on a carpet is further reduced.
  • the entire brush may be partly retracted and a front portion of the brush may be more retracted than a rear portion of the brush in the second setting.
  • the present embodiment is advantageous in that passing of relatively large pieces of dirt or dust under the front portion of the brush during a forward stroke of the nozzle is facilitated while the lower rear portion of the brush concentrates the suction power of the nozzle, thereby improving the cleaning performance of the nozzle.
  • the user tends to pick up dust more in the forward direction than in the backward direction, as the forward movement is typically in focus during vacuum cleaning. Therefore, it is advantageous to facilitate for dust (in particular relatively large pieces of dust or dirt) to pass under the brush in particular during forward motion of the nozzle.
  • the brush may be resiliently suspended in the nozzle head, which facilitates moving the nozzle over carpet edges and the like. Hence, the user friendliness of the all-around second setting is further increased.
  • the support means may be projected so as to support the nozzle head on the floor in the third setting.
  • the support means may be equally, or just slightly more, projected compared to the brush in order to reduce the gap between the brush and the surface to be cleaned so as to make the suction force more concentrated in the third setting, thereby improving the dust pick up of the nozzle.
  • the present embodiment is advantageous in that it reduces the risk of the resiliently suspended brush to collapse under the suction force, as the nozzle head is spaced from the surface to be cleaned by the support means.
  • the support means may be more projected in the third setting than in the second setting or equally projected in the third and second settings.
  • the brush may be a passive brush.
  • a passive brush in contrast to an active brush, is a non-driven brush, i.e. the brush is not adapted to move (such as rotate) in order to agitate dirt at the surface to be cleaned.
  • the rotating brush is typically used for agitating dirt in carpets and may preferably be turned off during cleaning of hard floor for reducing the risk of the rotating brush scratching the floor.
  • Brushes of the passive type is generally better suited for concentrating the suction force compared to active brushes, as they facilitate making the passage between the nozzle head and the surface to be cleaned more air tight.
  • the brush may be an active brush, i.e. a driven brush adapted to agitate dirt at the surface to be cleaned.
  • the mechanism comprises a single actuator arranged to actuate projection and retraction of both of the support means and the brush, which facilitates for a user to change between the three different settings since merely one actuator has to be operated.
  • the actuator may comprise a (rotary) control knob, which is advantageous in that a control knob may be smaller in size compared to e.g. a slide control adapted for three different settings. Hence, the nozzle is made more compact in size.
  • the mechanism may comprise at least one first suspension means for suspending the brush in the nozzle head, at least one slidable first cam portion arranged to cooperate with the at least one first suspension means for determining a level of projection of the brush, at least one second suspension means for suspending the support means in the nozzle head, and at least one slidable second cam portion arranged to cooperate with the at least one second suspension means for determining a level of projection of the support means.
  • the first and second cam portions may be operable by means of the actuator.
  • the profiles of the first and second cam portions may be adapted to determine the degree of projection/retraction of the brush and the support means in the three different settings.
  • the first and second cam portions may be incorporated in the same part or arranged as part of separate parts.
  • a vacuum cleaner may comprise a nozzle as defined in any one of the preceding embodiments.
  • the vacuum cleaner may be a canister vacuum cleaner.
  • the brush may comprise bristles.
  • the bristles may be compact, whereby the brush is more airtight, which improves (concentrates) the suction power of the nozzle.
