Definitions

  • the invention initially relates to an arrangement of a filter bag in an electric vacuum cleaner, wherein the vacuum cleaner has a nozzle projecting into the filter bag and the filter bag has an opening flap which pivots through the projecting nozzle into the filter bag interior.
  • this flap is usually made of the same material as the holding plate and is hinged in the region of the opening such that the protruding into the filter bag nozzle of the vacuum cleaner swings the flap toward the filter bag interior ,
  • the desired automatic closure can be achieved by a back against the flap, in the course of the opening folding movement exciting spring.
  • the force acting on the flap via the connecting piece acts over a region extending in accordance with the pivot axis.
  • the ground plan section of the facing nozzle area is likewise rectilinear, so more preferably parallel to the

  • the installation of the opening flap to the associated nozzle surface is effectively supported by a spring element which causes the automatic return movement of the opening flap into the closing position.
  • the spring element may in this case be formed, for example, in the form of a leaf spring or the like, which at one end is connected to the opening in the adjacent region at the bottom side of the retaining plate and at the other end acts on the opening flap.
  • the invention further relates to an electric vacuum cleaner with a nozzle for cooperation with a filter bag to be inserted into the vacuum cleaner.
  • a rectangular nozzle contour is proposed, with a curved line for forming a three-sided contour and with a rectilinear contour to form a fourth page.
  • Preference is given to the fourth, associated with the rectilinear contour side of an opening flap pivot axis of the filter bag, which opening flap closes the filter bag opening to be penetrated by the Staubsauberstutzen before or after the onset of the nozzle.
  • a curved line connecting the two ends of the rectilinear contour forms a substantially triangular contour, including radii different over the extension length of the curved line.
  • This selected floor plan configuration achieves an improved interaction with the opening flap of the filter bag with a good sealing effect between the connection piece and filter bag or filter bag holding plate in the area of the curved contour.
  • Particularly advantageous here is an embodiment in which the Stutzenwandung with the rectilinear contour forms the most freely projecting part of the nozzle.
  • the neck extends beyond the region of the curved contour in the region of the rectilinear contour, so that when the neck is inserted into the filter bag, the portion of the neck having the rectilinear contour is immersed in advance, in which case a preferably provided opening flap swings open and thus paves the way for the complete entry of the nozzle into the filter bag.
