Definitions

  • the present invention relates to the field of passive nozzles for vacuum cleaners.
  • the present invention relates to nozzles that can be tilted.
  • a vacuum cleaner is a device that uses a suction force generated by a fan or motor unit to create a particular vacuum or underpressure to suck up objects like dust, particles, fibres, hair etc. from surface such as e.g. floorings and carpets. Typically, this is done by means of a vacuum cleaner nozzle that is connected via a nozzle outlet to an extension tube and/or suction hose to a dust compartment, in which dust can be separated from a dust laden air stream.
  • the underpressure at the nozzle may e.g. be determined by the size of the air flow entering the nozzle, and the suction power generated by the motor unit.
  • An increased suction power may lead to improved dust pick up capability, but also to increased energy consumption of the motor unit and an increased motion resistance of the nozzle as it is moved across the surface being vacuumed.
  • WO 02/26097 A1 The issue of increased motion resistance has been addressed in WO 02/26097 A1 , in which a vacuum cleaner nozzle is disclosed which is pivotally mounted with respect to a nozzle outlet. As the nozzle is moved in a forward or backward direction, one of two working edges of the vacuum cleaner nozzle is slightly raised from the surface to allow air to bleed into the nozzle, thereby reducing the motion resistance of the nozzle.
  • vacuum nozzle is known from GB 2 109 224 A , in which two pivotable bodies (14), which are mounted on the housing (13), define the two floor contact edges of the vacuum nozzle.
  • a vacuum cleaner comprising a nozzle according to the first aspect.
  • the nozzle may be pushed and pulled across the surface in a reciprocating movement in which an underside of e.g. a suction plate of the nozzle, i.e. a side or portion at which the suction opening of the nozzle may be located, may be arranged substantially horizontal or parallel to the surface.
  • an underside of e.g. a suction plate of the nozzle i.e. a side or portion at which the suction opening of the nozzle may be located, may be arranged substantially horizontal or parallel to the surface.
  • the tilting motion of the inlet part may be realized as a relative change in angle between the underside of the inlet part and the surface being vacuumed.
  • the tilting motion may be caused by the motion resistance, i.e. frictional forces, between the nozzle and the surface as the nozzle is moved across the surface.
  • the same reasoning may be applied for a backward stroke, during which the inlet part may tilt such that a front portion of its underside is slightly raised from the surface being vacuumed to allow an increased air flow through a gap formed between the front portion of the inlet part and the surface and, as a consequence, reduce the motion resistance during the backward stroke.
  • the stop element or the elastic portion of the stop element may be attached to, or formed of, a portion of the intermediate part or a portion of the inlet part.
  • the elastic portion may comprise two parts arranged at the inlet part and the intermediate part, respectively.
  • the stop element 240 may define a maximum tilt angle ⁇ or gap between the inlet part 230 and the surface S.
