Definitions

  • the invention first relates to the arrangement of a Filter bag in an electric vacuum cleaner, the Filter bag has a holding plate that has an opening for the entry of dust into the filter bag and a deflectable one assigned to the edge side Has section that in the course of inserting the filter bag can be deflected into the electric vacuum cleaner, the electric vacuum cleaner a level indicator for the level of the filter bag in the electric vacuum cleaner has, with an indicator piston, the indicator piston movable by pressure difference on the filter bag is and has a piston skirt with a catch hook.
  • an actuating element in the form of a deflectable actuating section which has sufficient tolerance compensation so that interaction with the level indicator or its catch hook is possible even in the case of an unfavorable pairing of the tolerances of the holding plate and holding plate holder in the device.
  • the actuating section is arranged associated with an edge side of the filter bag or its holding plate, the actuating section being cut freely to the edge of the holding plate or being arranged in a bulge in the holding plate. When the actuating section is arranged in the region of a bulge in the holding plate, it is enclosed in a ring or fork shape.
  • the actuating section Due to the fact that the actuating section is manufactured with a certain oversize, an interaction with the level indicator is possible even with an unfavorable tolerance pairing.
  • the excess of the actuating section causes a deformation of the actuating section in the course of inserting the filter bag into the filter chamber, after which the latter is deflected upwards with its free edge, preferably running essentially parallel to the steering axis. This is due to a collision with the housing protruding upwards above the holding plate and / or the catch hook. It is furthermore advantageous due to the configuration according to the invention that the deflection of the actuating section in the course of inserting the filter bag via the deflected actuating section gives the user an indication that this filter bag has already been used.
  • the actuation section can - as already mentioned - be enclosed in a ring or fork shape.
  • the actuating section is deflected by a housing section which extends in overlap with the catch hook below the catch hook.
  • This housing section can be formed in the form of a rib protruding from the level indicator housing, against the upper edge of which the actuating section of the filter bag is deflected in the course of its insertion or in the course of a displacement of the filter bag into an operating position.
  • the catch hook can be hooked onto a side wall of the housing below a housing cover, which side wall has an opening in this regard, while penetrating the side wall.
  • the filter bag inserted with the actuating section deflected upwards acts upon this actuating section in the course of removing the filter bag from the catch hook, which at maximum fill level has passed through the housing opening and locks there in such a way that it is displaced through the opening back into the housing, to initiate a reset to the basic level indicator.
  • the catch hook preferably has a deflection slope pointing downward, ie in the direction of the actuation section deflected upwards.
  • the level indicator is reset when the filled filter bag is removed.
  • the reset can also be carried out by inserting a preferably new, unused filter bag.
  • the actuating section which is preferably initially aligned in one plane to the holding plate of the filter bag, is deflected by being acted upon by the level indicator housing, whereupon it acts on the catch hook which has passed through the housing opening in the course of the further inward displacement of the filter bag. The latter is thereby moved back due to the housing opening.
  • the actuating section In the operating position of the filter bag, the actuating section remains in the deflected position, preferably by contacting the housing section, for example the rib, in a position directed by approximately 90 ° to the holding plate extension.

  • the holding plate has a rectangular outline, with a longer and a shorter side, and that the actuating section is pivoted about an axis corresponding to the orientation of the shorter side.
  • the actuating section is assigned to a corner region of the holding plate, so further preferably in a first third of the longitudinal edge side of the holding plate in the longitudinal extent of the holding plate.
  • this is part of the holding plate.
  • the actuating section consists of the cardboard / paper material of the holding plate.
  • a holding plate made of cardboard / paper material usually consists of several, for example three or four layers. In order to form a deflectable actuating section here, it can be formed, for example, only over one layer.
  • the actuating section in addition, it is conceivable to form the actuating section by perforation, pre-break or compression in the area of the holding plate, so that a predetermined deformation is made possible. Furthermore, it is also conceivable to connect the actuating section to the holding plate via an elastic connecting member. It is also conceivable that, in the case of a holding plate to which a dust filter bag is attached, the actuating section is formed from a part of the dust filter bag, for example in an area of the dust filter bag which is folded in the fastening area of the holding plate and is therefore slightly stiffened. Finally, it is also conceivable that the actuating section consists of a flexible membrane.
  • the invention further relates to a filter bag with a holding plate, which holding plate one of the Has edge-associated, deflectable section.
