Definitions

  • the invention relates to a vacuum cleaner having a dust bag compartment.
  • Dust bag compartments of vacuum cleaners often have ribs to create a distance between the dust bag and the wall of the dust bag compartment. These ribs allow for air to move between the dust bag and the wall in directions dictated by the ribs in its path from the dust bag towards an inlet of the fan compartment.
  • the invention is based on the recognition that if air can only move in directions dictated by the orientation of the ribs, the air cannot directly move to the fan inlet. This leads to resistance, and thus to a loss in suction power. Additional, some locations in the dust bag compartment may not have ribs at all, at which locations there is no airflow possible through the bag, and the bag material is not used at all to separate and store dust.
  • the ribs on the walls of the dust bag compartment which allow airflow in one direction only, are replaced or supplemented by an open structure, so that an omnidirectional air movement is possible at each point of the three-dimensional open structure.
  • This open structure allows the air to exit the bag at all locations and move around outside of the bag towards the motor inlet via the path with lowest resistance.
  • the open structure should be stiff enough to ensure that it stays open even under weight of a filled dust bag.
  • a suitable 3D open material or structure can be a textile material as marketed by Muller Textil GmbH as 3mesh, and described in US2016273137 , which discloses a spacing knit fabric with first and second two-dimensional knit fabric layers, which are interconnected via knitted spacing threads.
  • the first two-dimensional knit fabric layer has openings formed by a plurality of stitches in each case. Threads of a first thread system, which forms the first two-dimensional knit fabric layer, are connected to each other solely by mutual intertwining. Channels are formed between the first and the second two-dimensional knit fabric layers that are free from spacing threads.
  • the threads of a second thread system, which forms the second two-dimensional knit fabric layer are connected to one another by intertwining and by at least partial fusion.
  • the walls of the dust bag compartment are provided with a large plurality of pillars (e.g. between 0.5 and 2 per cm 2 , and having a thickness of e.g. between 1 and 3 mm, preferably with a blunt top so as to prevent the dust bag from being damaged) that create a distance between the dust bag and the wall, while allowing air to move into and through the space defined by the pillars in a plurality of directions.
  • a large plurality of pillars e.g. between 0.5 and 2 per cm 2 , and having a thickness of e.g. between 1 and 3 mm, preferably with a blunt top so as to prevent the dust bag from being damaged
  • the walls are covered with the open structure.
  • the open structure is present up till the fan inlet structure. This ensures that the air that moves through the open material can reach the fan inlet filter with minimal thresholds.
  • the thickness of the open structure is typically around 5-25 mm. If the thickness is less, the resistance for the air increases, while if it is more, the space it takes will make the entire vacuum cleaner more bulky.
