Definitions

  • the invention relates to a vacuum cleaner filter bag and the use of a vacuum cleaner filter bag in a vacuum cleaner.
  • the EP 0 960 645 shows the EP 0 960 645 a multi-layer vacuum cleaner filter bag assembly, wherein in the air flow direction, a coarse filter layer is disposed in front of a fine filter layer.
  • the coarse filter layer should have a relatively high thickness and a high pore volume. This can delay a clogging of the bag over a longer period of time.
  • the EP 1 123 724 shows a multi-layer vacuum cleaner bag, which comprises a support layer of paper, the raw gas side is covered by a pre-filter made of microfibers, which performs the function of a release layer and is temporarily lifted from the support layer. This separating layer completely covers the base layer to ensure that the filter bag is sufficiently stable and filter-effective even when the paper layer is completely destroyed.
  • a protective layer in the form of a strip is provided inside the vacuum cleaner filter bag, which is also intended to prevent damage to the vacuum cleaner filter bag.
  • This protective layer is arranged such that particles entering the filter bag through an inlet opening impinge directly on the strip, so that the subsequent layer remains protected.
  • a filter bag is known in which a layer of abrasion resistant material is arranged on the inside.
  • the dust cleaner also has a deflection screen.
  • a deflector and a sheet of material having an unconnected portion enclosing a portion of the edge of the sheet of material provides a substantial improvement in the life of the vacuum cleaner filter bag.
  • the deflection device ensures that an airflow entering through an inlet opening of the vacuum cleaner filter bag does not strike directly against the inside of the bag opposite the inlet opening. An incoming air stream may thus flow under the at least partially unconnected with the vacuum cleaner filter bag material layer, so that it is at least partially spaced from the inside of the vacuum cleaner filter bag.
  • This air flow can continue to pass through the material layer away from the bag wall in the direction of the bag interior, resulting in a highly advantageous distribution of the filter cake inside the bag, whereby the service life of the vacuum cleaner filter bag is significantly increased.
  • the special feature is therefore that the material layer can at least partially be underflowed by an air flow, which can then pass through the material layer into the interior of the bag again.
  • connection of the material layer to the at least one point can be provided on the side facing the inlet opening and / or the side of the material layer facing away from the inlet opening, in FIG.
  • the unconnected part is not connected to the vacuum cleaner filter bag either on the side facing the inlet opening or on the side remote from the inlet opening.
  • the at least one part forms a coherent piece of the material layer.
  • the edge of the material layer comprises the side edges of the material layer; For example, if the material layer continues to have a slot, the edge also includes the edges of the material layer at the slot.
  • the material layer may have a smaller area than the area of the inside of the material layer. This advantageously enables an underflow of the material layer.
  • the area of the at least one part can make up at least 20% of the area of the material layer.
  • a convex amount can be formed on a surface of the material layer.
  • convex has the following meaning.
  • a lot M ⁇ R 2 is called convex if with every two points P and Q from this set also all points of the connection path between P and Q belong to M.
  • the term convex is thus used in the conventional sense, as it is for example in IN Bronstein, KA Semendjajew, Taschenbuch der Mathematik, 25th edition 1991, BG Teubner Verlagsgesellschaft and Verlag Nauka, chapter 3.1.2 , is mentioned.
  • the convex sets in the plane include triangles, rectangles, or slices. This meaning is decisive for a flat material layer.
  • a set M on a two-dimensional, possibly curved surface in three-dimensional space is called convex, if with two points P and Q from this set also all points of the connection path on the surface between P and Q belong to M. This meaning is decisive for a curved material layer.
  • the vacuum cleaner filter bag may be formed as a flat bag. In this case, it is preferable to judge the convexity in the flat state of the vacuum cleaner filter bag.
  • the at least one part may include the projection point resulting from a perpendicular projection of the geometrical center of gravity of the material layer onto the surface on one side of the material layer.
  • the unconnected part extends from one edge of the material layer to its middle.
  • a relatively large part of the material layer is unconnected, which increases the effect of the material layer in combination with the deflection device and results in an additional increase in service life.
  • the at least one part may include a path leading through the projection point on the surface whose end points each form the edge of the material layer.
  • the part extends from one part of the edge to another part of the edge. This makes it possible for an air stream to flow through under the material layer.
  • the at least one part may include at least 10% of the edge of the sheet of material.
  • the at least one part may include at least 30%, in particular at least 50%, in particular at least 70%, in particular at least 90% and / or in particular at most 95%, in particular at most 70%, of the edge of the material layer.
  • the at least one part, in particular the convex amount formed thereby, can make up an area of at least 40%, in particular at least 60%, in particular at least 80%, of the surface of the material layer.
  • the material layer may have a polygonal, in particular quadrilateral, shape, and the at least one part may include a part of at least two, in particular opposite, side edges of the material layer.
  • the material layer may be connected to the vacuum cleaner filter bag at a predetermined amount of points, preferably at exactly two points, and / or at two seams of the vacuum cleaner filter bag.
  • the material layer may have a rectangular shape and be connected to the vacuum cleaner filter bag only along two, in particular opposite, side edges, in particular the short sides.
  • the material layer can be glued or welded to the vacuum cleaner filter bag, in particular the inside of the bag, for example.
  • the material layer can comprise a nonwoven fabric, for example comprising a fine-fiber fleece (meltblown), a spunbond, a wet-laid nonwoven and / or a dried fleece, a paper or an air-permeable film, for example a perforated or slotted film.
  • a nonwoven fabric for example comprising a fine-fiber fleece (meltblown), a spunbond, a wet-laid nonwoven and / or a dried fleece, a paper or an air-permeable film, for example a perforated or slotted film.
  • the strip of material may have an air permeability of 100-10000 l / (m 2 s), more preferably of 1000-8000 l / (m 2 s), most preferably 1500-5000 l / (m 2 s).
  • the material layer may have an area of 10 - 80%, preferably 15 - 30% of the area of the inside of the bag.
  • the material layer may be connected to the inlet opening of the vacuum cleaner filter bag opposite to the vacuum cleaner filter bag of the vacuum cleaner filter bag.
  • the at least one part may have at least one slot. Through such a slot, an underflow of the material layer is further promoted. If the material layer has at least one slot, in particular with a large length, the material layer can, for example, cover the entire surface of the inside of the vacuum cleaner filter bag. Nevertheless, an underflow is ensured by the at least one slot.
  • the material layer may have a plurality of slots. In a flat bag, the material layer, if it has at least one slot, cover a bag wall, in particular the bag wall opposite the inlet opening over the entire surface.
  • the vacuum cleaner filter bag can be designed as a flat bag with two rectangular filter material layers connected to one another along the edge.
  • the air-permeable material layer may be connected to the filter material layer opposite the inlet opening of the vacuum cleaner filter bag, in particular in the center.
  • the material layer may have a rectangular shape with a width of 10-80%, preferably 25-45%, the width of the associated filter material layer and / or a length of 60-100%, preferably 100%, of the length of the associated filter material layer.
  • the material layer may comprise at least one laminate, in particular an SMS.
  • a laminate several layers of material are bonded together. For example, a spunbond, a meltblown and a spunbond are linked together in an SMS.
  • the material layer may comprise a film fiber net.
  • film fiber networks arise, for example, in the fibrillation of extruded films and provide a precursor of film fiber nonwovens (see eg " Nonwovens ", W. Albrecht, F. Fuchs and W. Kittelmann, Wiley VCH, Weinheim, 2000 ).
  • the material layer may include netting.
  • Such a fiber network can be obtained by extrusion and deposition of the fibers.
  • the material layer may comprise, in the vacuum cleaner filter bags described above, individual interconnected fibers or may consist of individual interconnected fibers.
  • the directions of the longitudinal axes of the individual non-bonded fibers may include an angle of less than 45 ° to each other.
  • the fibers can therefore be arranged parallel to one another.
  • unconnected and unconnected single fiber is meant here that the fibers are not interconnected substantially along their longitudinal direction. However, this should not be ruled out that they can have a local connection to one another via the at least one connection point with the vacuum cleaner filter bag.
  • the fibers cited in this application have relatively large fiber lengths of a few centimeters up to the length or width of the vacuum cleaner filter bag.
  • the non-interconnected fibers may be staple fibers, in particular polypropylene.
  • the fibers may be oriented substantially parallel to the direction of air flow at the inlet opening prior to deflection by the deflector or perpendicular to that direction, or may include an angle substantially between 0 ° and 90 ° to this direction substantially parallel to one another.
  • the fibers may thus be arranged in particular parallel to one of the edges. These individual fibers can be arranged side by side with or without spacing from one another or else overlapping one another.
  • Each of the fibers has first and second ends in the fiber longitudinal direction and may be attached to both the first end and the second end with the vacuum cleaner filter bag be connected.
  • the connection may be formed by a transverse connection over the ends, such as a transverse welding or adhesive seam.
  • all or some of the fibers perpendicular to the fiber longitudinal direction may be connected to the vacuum cleaner filter bag by one or more line or sheet connections.
  • the line or area connections may be at an angle of less than 90 ° to the fiber's longitudinal direction.
  • Individual fibers are an advantageous embodiment of the air-permeable material layer in that they are easy and inexpensive to manufacture, have high air permeability and easily allow the airflow passing through the inlet opening and deflected by the deflector to flow under them and thus to a spacing of the airflow from the fibers existing or this comprehensive material situation. By aligning the fibers and spacing between them, the air flow can be finely regulated.
  • the above-described vacuum cleaner filter bags may include an additional air-permeable sheet of material disposed inside the vacuum cleaner filter bag connected at least at one location to the vacuum cleaner filter bag and / or the other air-permeable sheet of material and having at least a portion connected to the vacuum cleaner filter bag and / or the other air-permeable material layer is unconnected and includes part of the edge of the material layer.
  • the above-described effect of the other or first material layer can be further enhanced.
  • a part of an air flow can also flow between the two material layers.
  • the two layers of material can be connected, for example, to two hems of the vacuum cleaner filter bag.
  • one of the material layers or the two material layers may have at least one slot.
  • both layers of material may have at least one slot at a different position.
  • the material layers can be arranged at different positions or one above the other in the vacuum cleaner filter bag.
  • the deflector may at least partially surround the inlet opening of the vacuum cleaner filter bag and be secured to the bag inner side.
  • a stable arrangement of the deflection device is obtained which can reliably fulfill its task even at high flow velocities.
  • the deflecting device can be designed to split the air flow into at least two partial flows.
  • the deflecting device can be designed to divide the air stream into at least two partial streams with opposite directions of flow.
  • air enters the flow direction (inlet flow direction) through an inlet opening of the deflection device and is deflected therein, so that a change in the flow direction in the deflection device with respect to the flow direction at the inlet opening occurs.
  • 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. During operation of the vacuum cleaner, such a main flow direction results at every point through the vacuum cleaner tube into the bag, even if turbulence may possibly occur at individual points.
  • 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, ie a component perpendicular to the inlet flow direction, wherein the two components enclose an angle of about 180 ° and wherein the components are each greater in this plane than the corresponding component parallel to the inlet flow direction.
  • the deflecting device may comprise at least one, preferably plane, deflecting surface opposite the inlet opening.
  • deflecting or baffle surface By means of such a deflecting or baffle surface, in particular the velocity of the particles can be reduced in a suitable manner.
  • a deflection surface opposite the inlet opening of the deflection device may in particular have a distance therefrom or a mean distance of between 1 cm and 15 cm, in particular 2 cm to 5 cm.
  • the at least one deflection surface may have a larger area than the area of the inlet opening. This largely avoids that an air flow is merely deflected around the deflection surface and then strikes the bag wall opposite the inlet opening with a substantially unchanged flow velocity. Instead, it is achieved by the same or larger area that the air flow is deflected so that it can flow in a suitable manner under the material layer.
  • Each deflection surface may have an area of 15 cm 2 to 100 cm 2 , in particular 40 cm 2 to 60 cm 2 .
  • the at least one deflection surface may be arranged at a predetermined angle relative to the plane of the inlet opening.
  • the deflection of the air flow under different parameters such as vacuum cleaner motor power, arrangement of the vacuum cleaner filter bag, or, whose geometry and dimensions, Einströmwinkel, arrangement and dimensioning of the material layer, etc. are adjusted and optimized.

  • the deflection device may be designed such that an air flow passing into the deflection device can be deflected in the deflection device by at least 45 °, preferably at least 60 °, more preferably at least 80 °.
  • the air flow direction when exiting the deflector with the flow direction when entering the deflector includes an angle of at least 45 °. This results in an advantageous direction of air flow into the vacuum cleaner filter bag.
  • the deflection device may comprise the shape of a cylinder, truncated cone, cuboid or truncated pyramid, which has an inlet opening in the top surface and at least one outlet opening in the side wall.
  • the deflection direction of the previously described vacuum-cleaner filter bags can be designed such that, in a first position, they have a reduced extent, compared to a second position, perpendicular to the plane of the inlet opening.
  • the deflection is collapsible. Due to the smaller extent in the second position, the vacuum cleaner filter bag can be brought into a very compact form, in particular before use. This is of particular advantage in the case of flat bags, which can be folded up in particular for packaging to specific formats. By means of such collapsible deflection devices, it is possible to avoid that the thickness of the folded-up bags is substantially increased.
