Definitions

  • the present invention relates generally to the field of vacuum cleaners. More specifically, the present invention is related to a vacuum cleaner nozzle with a lighting device.
  • a vacuum cleaner is a device that uses a suction force generated by a fan unit to create a partial vacuum to suck up objects like dust, particles, fibres, hair etc. usually from floors and carpets.
  • a vacuum cleaner nozzle which is connected via a nozzle outlet to an extension tube and/or a suction hose to a dust compartment within the body of the vacuum cleaner.
  • the suction hose is normally engaged with a removable dust bag arranged inside the dust compartment for collecting dust and foreign materials that are sucked in through the vacuum cleaner nozzle when the vacuum cleaner is in an operative mode.
  • the dust laden air stream forwards the removed objects, via the hose, to the body of the vacuum cleaner in which the removed objects are separated from the air stream in the dust bag.
  • dust can be separated from the dust laden air stream using a cyclone or other suitable dust separating unit.
  • US Patent Application US 2006/0096057 A1 discloses an illumination accessory assembly for vacuum cleaner including a transparent extension having a first end capable of releasable connection to a vacuum cleaner hose and having a distal vacuum cavity intake end.
  • a LED is positioned so the LED illumination transverses the transparent extension medium and exits the distal end and walls of the transparent extension.
  • the LED illumination provides the operator an illuminated clear line of sight around and through the transparent extension of the area to be cleaned and illuminates the contents in the initial vacuum cavity of the transparent extension for improved operator cleaning efficiency.
  • US Patent Application US 2008/301899 A1 discloses a nozzle with a lighting device for illuminating an area.
  • US Patent US6256833 B1 discloses an upright vacuum cleaner with a lightning device.
  • GB Patent application GB2456418 A discloses a vacuum cleaner nozzle with a lightning device, preferably LED:s emitting light in the ultraviolet spectrum is used.
  • a drawback of known vacuum cleaners comprising a lighting device is that the lighting device has to be manually activated and deactivated which clearly worsen the usability of the vacuum cleaner. Accordingly, there is a need for improvements of existing vacuum cleaners comprising lighting devices in order to increase the usability of the vacuum cleaner.
  • the invention is intended for battery powered vacuum cleaners as well as mains-operated vacuum cleaners.
  • the invention can be used in a canister vacuum cleaner, upright vacuum cleaner, or stick vacuum cleaner. It could also be used in a robotic vacuum cleaner.
  • the invention relates to a nozzle for vacuum cleaners comprising a housing with a suction channel, a lighting device configured to illuminate an adjacent area to be cleaned and switching means for activating said lighting device, wherein the nozzle comprises sensing means adapted to determine a measurement value at the nozzle and the switching means coupled to said sensing means are adapted to automatically activate the lighting device if the measurement value is above a predefined threshold value.
  • the nozzle is adapted to activate the lighting device automatically based on the sensed measurement value.
  • the nozzle and the vacuum cleaner body are electrically decoupled.
  • the nozzle comprises no means for electric coupling of the lighting device to the vacuum cleaner body, i.e. there is no wired or wireless electrical connection between the nozzle and the vacuum cleaner body.
  • the vacuum cleaner nozzle is adapted to autarkically, respectively, automatically perform the switching and operation of the lighting device, i.e. without any operational connection to the vacuum cleaner body.
  • an upgrade of a vacuum cleaner with a nozzle according to the invention is possible.
  • the switching means are adapted to activate the lighting device when the vacuum cleaner is turned on and adapted to deactivate the lighting device when the vacuum cleaner is turned off. Thereby an effective switching of the lighting device is achieved and electrical power can be saved because the lighting device is automatically switched off when the vacuum cleaner is turned off.
  • the sensing means are constituted by a pressure sensor adapted to measure the vacuum within the suction channel of the nozzle.
  • vacuum is generated within the suction channel of the vacuum cleaner nozzle.
  • the operational status of the vacuum cleaner can be determined. If the vacuum level within the suction channel exceeds a predefined threshold value, the lighting device may be switched on.

  • the electrical circuit may be a filter and delay circuit with at least one capacitor for providing electrical power to the lighting device independent of short-time discontinuities of the electrical power supply due to undesirable switching characteristics.
  • the lighting device is constituted by at least one light emitting diode (LED).
  • LED light emitting diode
  • light emitting diodes comprise a long life time and are extremely energy-efficient. Thereby, even if the lighting device is battery-powered, the life period of the batteries is extremely long.

  • the invention refers to a vacuum cleaner comprising a nozzle according to any one of the preceding embodiments.
  • the invention refers to a method for activating a lighting device of a vacuum cleaner nozzle, the nozzle comprising a housing with a suction channel and switching means for activating said lighting device, wherein the lighting device is configured to illuminate an adjacent area to be cleaned, wherein a measurement value is determined at the nozzle by means of sensing means and the lighting device is activated by means of the switching means, if the measurement value is above a predefined threshold value.
