Definitions

  • the present invention generally relates to the field of vacuum cleaner nozzles having a sealing edge at the suction opening.
  • Vacuum cleaner nozzles comprising multiple joints in the connection between the nozzle outlet and the extension tube and/or suction hose for increased performance on uneven and soft surfaces are known.
  • the multiple joints allow the vacuum cleaner nozzle to adapt to the surface and thereby pick-up more dust as the hose and the vacuum cleaner nozzle is operated over a floor or a carpet.
  • WO 02/26097 discloses a vacuum cleaner nozzle which is pivotally mounted with respect to a nozzle outlet, such that movement of the vacuum cleaner nozzle in a forward and backward direction alternately brings one of two working edges of the vacuum cleaner nozzle (or sealing edges which are arranged to restrict the air flow from areas surrounding the active suction area of the vacuum cleaner nozzle on soft surfaces) in closer contact with the surface being vacuumed.
  • the protrusion provides a first secondary sealing edge extending along at least a portion of a first primary sealing edge and is further horizontally displaced from the first primary sealing edge.
  • the sealing edges are arranged for engaging with a surface being cleaned and for at least partly sealing the suction opening against the surface being cleaned.
  • the first secondary sealing edge decreases the size of under pressure drops that are created at the inlet side if the vacuum cleaner nozzle for some reason suddenly loses its close contact with the surface being cleaned (i.e. if the first primary sealing edge of the suction plate is suddenly tilted too far up from the surface).
  • the under pressure drop of the vacuum cleaner nozzle can be kept more controlled as the vacuum cleaner nozzle is moved across carpets or any textile or soft surface, and when the nozzle is tilted too much so that under pressure would otherwise have dropped. If the under pressure is lost under the vacuum cleaner nozzle, the dust removal ability is temporary decreased, as the under pressure has to be built up again.
  • the nozzle obtains a more controlled under pressure of the vacuum cleaner nozzle by allowing the under pressure to decrease in smaller steps as the first secondary sealing edge supports a less abrupt change in surface contact to the surface being cleaned.
  • the annoying jumping effect and vibration effect in the vacuum cleaner nozzle due to sudden under pressure drops are then decreased.
  • the secondary sealing edge provides better dust removal ability from carpets as well as a more comfortable cleaning experience.
  • the protrusion of the suction opening providing the first secondary sealing edge implies challenges in manufacturing of the suction plate, as the plastic moulding tool must be inserted from the top of the suction plate, which requires a rather large opening in the air duct of the suction plate. Alternatively, a separate part must be attached to the suction plate for forming the protrusion.
  • DE 103 01 113 A discloses a vacuum cleaner nozzle with improved thread pick-up features.
  • the nozzle comprises thread pick-up modules swiveling around a pivot axis. Each module swivels outwards for the intake of fibers and swivels inwards for releasing the fibers.
  • the thread pick-up is inclined towards the suction mouth opening, after an inwardly swivel movement of the thread pick-up module.
  • 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 suction plate which comprises a suction opening for the purpose of taking in dust from a surface being cleaned, an outlet and an air duct extending through the suction plate from the suction opening to the outlet, the air duct having an end portion arranged to extend towards (such as up to) the suction opening in a direction being substantially vertical when the nozzle is in an operation position on the surface being cleaned.
  • the suction plate further comprises a sealing edge arranged to engage with the surface being cleaned and to at least partially seal the suction opening against the surface being cleaned.
  • the sealing edge extends along at least a portion of the suction opening, wherein a first portion of the sealing edge is arranged to be displaced in a natural (or normal) movement direction of the nozzle with respect to a second portion of the sealing edge. Further, the end portion of the air duct is arranged to be constantly flared and/or straight in the vertical direction towards and up to the first portion of the sealing edge and constantly flared and/or straight in the vertical direction towards and up to the second portion of the sealing edge.
  • vertical and horizontal directions are the directions which are vertical and horizontal, respectively, when the nozzle is positioned on a surface (such as a floor) to be (or being) cleaned, such as during normal operation of the nozzle.
  • the horizontal plane may be equal to the plane in which the suction plate generally extends (i.e. a plane being substantially parallel with the surface to be cleaned).
  • a horizontal direction may be any direction along the plane in which the suction plate generally extends.
  • a vertical direction may be a direction substantially perpendicular (or transverse) to the plane in which the suction plate generally extends.
  • the end portion of the air duct being arranged to be constantly flared and/or straight with respect to the vertical direction (or with respect to a direction perpendicular and/or transverse to the plane in which the suction plate generally extends) towards and up to the first portion of the sealing edge and towards and up to the second portion of the sealing edge, facilitates manufacturing of the suction plate.
  • the vertical direction as defined in the present specification may be the same as the tooling direction, i.e. the direction in which a tool for moulding the shape of the end portion of the air duct is inserted and removed.
  • the moulding tool may be inserted from the underside of the suction plate into the suction opening.
  • the protrusion of the sealing edge i.e. the displaced portion
  • the air duct being partially tapered in the vertical direction towards the sealing edge.
  • Such tapered shape of the air duct necessitates that the moulding tool is inserted in the air duct from the upper side of the suction plate (to enable removal of the tool at the end of the moulding process), whereby a relatively large opening has to be provided in the air duct on the upper side of the suction plate.
  • the opening must be sealed with a lid in order to make the air duct air tight.
  • a lid may require rather complex fastening methods, such as welding, to reduce the risk of air leakage.
  • fastening of the lid may be facilitated.
  • the lid may be force fitted (press fitted) at the opening.
  • first and second portions of the sealing edge being displaced relative to each other in the natural movement direction of the nozzle provides similar benefits as the prior art nozzle shown in WO 2009/128763 and described above, i.e. improved dust removal ability from carpets as well as a more comfortable cleaning experience.
  • the end portion of the air duct being "constantly flared and/or straight" it is meant that the end portion of the air duct does not have any portion being tapered in the vertical direction towards (and up to) the first and second portions of the sealing edge.
  • the end portion of the air duct may be flared (i.e. divergent with respect to the vertical direction) and/or straight (i.e. substantially parallel with the vertical direction) at any given portion.
  • the suction plate may be made of plastic.
  • the suction plate may be moulded in plastic.
  • Plastic is a light weight and low cost material, thereby reducing the weight of the nozzle and manufacturing costs. The moulding operation is facilitated as the moulding tool may be inserted and removed from the underside of the suction plate.
  • the first portion of the sealing edge may be positioned at a mid (or center) portion of the sealing edge, such as at a mid portion of the suction opening.
  • the under pressure created between the vacuum cleaner nozzle and the surface being vacuumed may be larger at the mid portion of the suction plate.
  • the end portion of the air duct is arranged to be more flared in (or with respect to) the vertical direction towards and up to the second portion of the sealing edge compared to in (or with respect to) the vertical direction towards and up to the first portion of the sealing edge so as to provide the displacement of the first portion of the sealing edge relative to the second portion of the sealing edge in the natural movement direction of the nozzle.
  • the suction opening may be elongated, such as having a substantially rectangular shape, and the first portion of the sealing edge may be arranged at the centre of a long side of the elongated suction opening.
  • the present embodiment is advantageous in that that the rectangular shape of the suction opening is better adapted for the normal operation of the vacuum cleaner nozzle during vacuuming, i.e. the forward and backward stroke of the vacuum cleaner nozzle in a direction being perpendicular to the longitudinal direction of the rectangular suction opening.
  • the positioning of the first portion of the sealing edge at the centre of one of the long sides of the suction opening then provides for encountering a plurality of irregularities in the surface being vacuumed simultaneously, while still having the most advantageous positioning with respect to the distribution of the strength of the under pressure created beneath the suction plate.
  • the first portion of the sealing edge may be displaced in the natural movement direction of the nozzle with respect to the second portion of the sealing edge by a distance corresponding to between 0.5 to 40 %, such as 0.5 to 10 %, of the width of the suction opening.
  • the width of the suction opening means the width of the suction opening in the natural movement direction of the nozzle.
  • the sealing edge may be a first sealing edge and the suction plate may comprise a second sealing edge arranged opposite to the first sealing edge.
  • the suction opening may be sealed both during the forward stroke and the backward stroke during cleaning.
  • the first portion of the second sealing edge may be arranged to be displaced in the natural movement direction of the nozzle with respect to a second portion of the second sealing edge, and the end portion of the air duct is arranged to be constantly flared (or divergent with respect to the vertical direction of the vertical portion of the air duct) and/or straight (i.e.
  • the second sealing edge may be similarly configured as the first sealing edge, thereby providing the same benefits as the first sealing edge at the opposite stroke during operation of the nozzle.
  • the nozzle may further comprise at least one lint picker arranged at the suction plate along the first portion of the sealing edge, which facilitates picking up hair and fibres from soft surfaces, such as carpets.
  • a vacuum cleaner may comprise a nozzle according to any one of the preceding embodiments.
  • the nozzle may be configured as the nozzle described in WO 2009/128763 , except that the step provided by the protrusion forming the secondary sealing edge of the nozzle described in WO 2009/128763 is replaced by the second portion of the sealing edge according to the present aspect, whereby the vertical end portion of the air duct may be at least partly flared instead of tapered in order to form the step.
  • Figure 1 shows a vacuum cleaner 100 comprising a nozzle 101 according to an embodiment.
  • the nozzle 101 may be connected to a main body 104 of the vacuum cleaner 100 via a tube 102 and a hose 103.
  • FIG. 2 is an exploded view of a nozzle 1 comprising several rigid parts 7, 16, 17 interconnected to each other by one or more joints 14, 15 (or hinged connections).
  • the nozzle 1 comprises a suction plate 7 connected to an intermediate part 16 via a hinged connection 14, whereby the suction plate 7 is arranged to pivot relative to the intermediate part 16.
  • the nozzle 1 further comprises an outlet part 17 adapted to be (directly or indirectly) coupled to the hose of the vacuum cleaner and connected to the intermediate part 16 via a hinged connection 15.
  • the three rigid parts 7, 16, 17 may be arranged to, at least slightly, pivot relative to each other in order to facilitate movement of the nozzle over uneven surfaces.
  • An air duct is formed in the suction plate 7, the intermediate part 16 and the outlet part 17 for guiding air and dust from a surface being cleaned towards the hose of the vacuum cleaner.

  • the suction plate 7 will tilt during forward movement of the nozzle 1 (as allowed by the pivotal connection between the suction plate 7 and the intermediate part 16), whereby the first sealing edge 18 will engage with the surface being cleaned.
  • the suction plate 7 will tilt in the opposite direction such that the second selaing edge 19 engages with the surface being cleaned.
  • the tiliting motion of the suction plate 7 occurs naturally during movement of the nozzle 1 back and forth in the natural (or normal) movement direction 20 of the nozzle 1.
  • the suction opening 2 may preferably be elongated, and the first and second sealing edges 18, 19 may extend along the long sides of the suction opening 2.

  • the suction opening 2 is (slightly) more narrow at the first portions 5a, 5b, of the first and second sealing edges 18, 19 than at the second portions 6a, 6b, of the first and second sealing edges 18, 19.
  • the first portions 5a, 5b, of the first and second sealing edges 18, 19 are arranged at a mid portion of the elongated suction opening 2.
  • the displacement of the first portions 5a, 5b relative to the second portions 6a, 6b may correspond to between 0.5 to 40 %, such as 0.5 to 10 %, of the width of the suction opening 2 (in the natural movement direction 20 of the nozzle 1).
  • the nozzle 1 may further comprise lint pickers 21 arranged at the underside of the suction plate 7, such as along the first and second portions 5a, 5b of the first and second sealing edges 18, 19.
  • the lint pickers 21 may comprise a strip of a material in which tufts of fine fibre are secured during cleaning.
