Definitions

  • the invention relates to a holding plate for a vacuum cleaner filter bag, which is attachable to a holding device in a vacuum cleaner housing for holding the vacuum cleaner filter bag.
  • vacuum cleaners which work with vacuum cleaner filter bags
  • the latter are arranged in the housing of the vacuum cleaner.
  • a holding plate is provided on the filter bag, which is attached to a holding device in the vacuum cleaner housing, so that in this way the vacuum cleaner filter bag is held in the housing.
  • Such holding plates are often glued or welded in conventional vacuum cleaner filter bags with the filter material of the bag. Since the holding devices of different types of vacuum cleaner generally differ, for each different type of vacuum cleaner, a corresponding vacuum cleaner filter bag must be made and purchased with matching holding plate.
  • adapter plates that are each tuned to a holding device of a particular vacuum cleaner.
  • This adapter plate is designed so that it can be releasably connected to a universal vacuum cleaner filter bag. In this way, it is sufficient to provide different adapter plates for the different vacuum cleaners or their holding devices, although a uniform filter bag can be used.
  • Such adapter plates are for example from the WO 00/36966 , of the DE 20 2005 010606 or the EP 1 607 034 known.
  • a vacuum cleaner filter bag with a filter structure in which a coarse filter layer is arranged in front of a fine filter layer in the direction of the air flow.
  • the coarse filter has a high dust storage capacity, so that dust particles in its pores can be stored over the entire thickness. In this way, a clogging of the filter material is delayed and thus increases the service life of the bag.
  • a holding plate for a vacuum cleaner filter bag which comprises a slip-on sleeve for the bag. Clamping blocks are provided which secure the filter bag.
  • the US 5,544,385 disclosed an assembly for securing a filter bag in a vacuum cleaner.
  • a solid plate is fastened to the housing of the vacuum cleaner.
  • An air deflector extends from the fixed plate so that it is inserted into the filter bag when inserted into the vacuum cleaner.
  • the BE 529 649 discloses a closure element for the opening in a vacuum cleaner bag, wherein the closure element may be formed as a flexible band in the form of a loop.
  • the dirt collector is part of a connecting element and extends transversely to the direction of movement of the air to be filtered.

  • the deflecting device comprises at least one, preferably flat, deflection surface opposite the passage opening; and wherein the at least one deflection surface has a larger area than the area of the passage opening.
  • the deflecting device may in particular comprise at least one outflow opening, which is arranged in the bag interior after connecting the holding plate to the vacuum cleaner filter bag, so that a deflected in the deflector air flow can flow into the bag interior.
  • the at least one deflection or baffle surface opposite the passage opening can in particular reduce the velocity of the particles in a suitable manner.
  • the distance or the average distance of such a deflection of the Passage opening may depend in particular on the size and shape of the vacuum cleaner filter bag or vacuum cleaner, for which such a holding plate should be provided.
  • Each deflection surface may have an area of 15 to 100 cm 2 , in particular 40 to 60 cm 2 .
  • the baffle is formed as part of a retainer plate which also has attachment means for non-destructively detachable connection to a vacuum cleaner filter bag
  • a retrofit member is provided in this manner which can be connected to a variety of vacuum cleaner filter bags as far as they are for connection to the retainer plate are formed suitable. This further allows that the vacuum cleaner filter bag itself can be made only with little effort, since the deflector is provided on the side of the holding plate. This, on the one hand, reduces the complexity of the manufacturing process of the filter bags; on the other hand, the filter bags can be folded to smaller dimensions and / or pack.
  • flow direction of the air flow or air flow direction is meant the main flow direction of the air, which runs generally parallel to a wall, for example a vacuum cleaner pipe or nozzle.
  • main flow direction results at any point through a vacuum cleaner tube into the bag, even if turbulence may possibly occur at individual points.
  • the deflection device can in particular be non-destructively releasably connected to the base plate.
  • the fastening device can be designed to form a non-positive or a positive connection.

  • a deflection surface opposite the passage opening can have a distance or an average distance of between 0.5 cm and 5 cm, in particular 2.5 cm to 4 cm, in particular from the latter.
  • the deflection device can be designed, in particular, for dividing the air flow into at least two partial flows with opposite directions of flow.
  • Opposing flow directions means that both flow directions have a component in the plane perpendicular to the flow direction, with which an air flow enters the deflection device through the passage opening, ie a component perpendicular to the inlet flow direction, wherein the components enclose an angle of approximately 180 ° and the components in this plane are each larger than the corresponding component parallel to the inlet flow direction.
  • the deflecting device can be designed such that an air flow passing into the deflecting device in the deflecting device can be deflected by at least 45 °, preferably at least 60 °, more preferably at least 80 °, compared to the air flow at the passage opening.
  • the air flow direction forms an angle of at least 45 ° when exiting the deflecting device with the flow direction at the passage opening. This results in a particularly advantageous air flow direction in a vacuum cleaner filter bag.

  • the base surface of the cuboid deflector may have at least one opening, which forms an outflow opening with an opening in a side surface.
  • the distance between the side surface of the cuboid deflector and the bag wall due to the geometry of the bag and the vacuum cleaner housing is low (for example, in American upright vacuum cleaners), so that at an outflow only in a sidewall a clogging problem may occur.
  • each outflow opening can occupy substantially the entire width of the side surface of the cuboid. This avoids that in the operation of the holding plate in a corner of the cuboid sucked in dust particles accumulate.
  • a deflection device provided in the form of a cuboid, in particular at least two opposite outflow openings can be provided.
  • the retaining plates described above may have a deflection device, which is designed in such a way that, in a first position, it has a reduced extent, compared to a second position, perpendicular to the plane of the passage opening.
  • the holding plate Due to the smaller extent in the second position, the holding plate can be brought into a very compact form. Thus, the holding plate can be packaged and transported in an advantageous manner.
  • the deflection device may be formed substantially flat in the first position.
  • the deflecting device may be designed such that it assumes the first position when the holding plate is not supported by the holding device, and that it can be brought into the second position when the vacuum cleaner filter bag is held by the holding device.
  • the deflecting device can thus be brought to the second position already when attaching the holding plate to the holding device. Upon removal from the fixture, the deflector will return to the first position.
