Definitions

  • the present invention relates to a flat bag for vacuum cleaners which has in its interior at least two diffusers made of material strips and / or flat structures with elongated flow openings.
  • Such flat bags are characterized by an excellent dust storage capacity and an extension of the service life.
  • EP 1 787 560 shows flow distributors in the form of boxes or strips of material attached in the area of the inlet opening of the filter bag, which are able to divide the incoming air flow into partial flows and to deflect it.
  • the idea is expanded to the effect that a second flow distributor complements the function of the first flow distributor. From the DE 20 2008 008 989 and the DE 20 2008 003 248 combinations of two flow distributors with a spacer are known.
  • a filter bag which comprises a bag with an interior which is divided into at least two chambers.
  • the subdivision is carried out by a partition which is fixed on three side edges, a transition between the first and the second chamber being formed on the fourth side edge.
  • the partition is only welded to the filter layers on one side edge for the entire length and is welded on the opposite side to a strip on the upper layer of filter material.
  • the DE 20 2008 007 717 describes a filter bag in which a flat, multi-layer filter insert is arranged in the interior, which is at least partially connected to the filter bag walls. Dust should be stored between the at least two layers of the filter insert.
  • the upper of the two layers can be perforated or slotted.
  • the filter insert can be designed as a continuous strip which is fixed on two opposite edges of the bag.
  • the DE 20 2007 010 692 relates to a filter bag in which a filling layer of fiber or yarn material extends between the two filter walls, which is connected to both filter walls and is pulled apart when the bag is unfolded so that a net-like structure is created in the bag.
  • a dust filter bag with a piece of baffle wall fitted inside is known.
  • This retaining wall piece is attached in front of the inlet opening of the bag in such a way that it bulges out during operation and forms two outlet openings through which the air flow is deflected. It is essential to the invention that the stowage wall piece is attached at a distance from the bag seam and does not come into contact with the rear bag wall under the pressure of the air stream.
  • Another air distributor is from the DE 10 2006 051 117 known. At least two material layers are arranged one above the other between the bag walls, the layers having a smaller extension than the two bag walls in a first surface direction and the same extension as the bag walls in the surface direction orthogonal to the first surface direction. Microfiber fleece or paper are named as materials.
  • the DE 2006 016 304 discloses a bag with at least one guide element by means of which the incoming air stream can be deflected.
  • the guide element is fixed adjacent to the inflow opening.
  • a bag from Miele that is already on the market has an arrangement of a deflection device which is attached directly below the inlet opening.
  • This deflection device consists of a flat structure which is attached directly to the top of the bag on both sides of the inlet opening.
  • the purpose of this deflection device is to deflect the air flow sucked in through the inlet opening directly in the area of the inlet opening.
  • This deflection device is designed such that it is welded directly to the bag wall at a distance from the inlet opening due to a predetermined length or area. The area of this deflector is therefore less than about 10% of the bag surface.
  • This filter bag is in Fig. 3 outlined.
  • the problem with these bags is that due to the relatively small dimensions of the first deflection device (SR1), the bag can become clogged by dust that has collected between the inflow opening and the deflection device, so that the bag becomes unusable.
  • SR1 first deflection device
  • the DE 20 2008 008 989 U1 describes a vacuum cleaner filter bag comprising a bag wall made of filter material, an inlet opening being provided in the bag wall, a deflecting strip, a material strip which is arranged inside the vacuum cleaner filter bag and connected to the bag wall, and a spacing means.
  • a flat bag for a vacuum cleaner with a bag top and a bag bottom is provided, the bag walls of which are formed from an air-permeable filter material and an inlet opening for the air to be filtered is made in the bag top, wherein inside the flat bag below the bag top in a first At least one diffuser is provided between the first plane and the underside of the bag in at least one further plane in each plane, the diffuser consisting of at least two mutually arranged strips of material and / or flat structures with elongated flow openings and the diffusers at least on one side are attached to the bag wall, with the proviso that the diffusers are in the form of flat structures with elongated flow openings, which are arranged in the first plane in the area of the inlet opening and on both sides on the top of the bag are attached with an area of ⁇ 10%, based on the entire bag surface, the width of the material strips being defined by the diameter of the inflow opening ⁇ 50%, are excluded.
  • the diffusers which are formed from strips of material or flat structures provided with flow openings, cause swirling of the inflowing dirt and / or dust particles Air. In this way, surprisingly, the service life of the bag can be significantly extended.
  • the flat bags according to the present invention contain diffusers in at least 2 levels for swirling the sucked-in dust particles.
  • a plane is understood to mean a curved or uncurved surface which is arranged between the top and bottom of the bag forming the bag wall.
  • the planes in the sense of the invention are thus defined by the arrangement of the diffusers in the interior of the filter bag by connecting the diffuser at at least 1 point on the bag wall.
  • a flat bag with 2 levels is therefore structured as follows, for example: The first level is understood to be the diffuser that faces the top of the bag, and the second level is the diffuser that is arranged below the first level and faces the bottom of the bag. Each additional level is inserted between the 2nd level and the bottom of the bag.
  • the diffusers made of a pliable material are either formed from at least two material strips arranged in relation to one another, but can also consist of flat structures which have flow openings in the sense of slots within these flat structures. Such flat structures thus have at least one slot or a severing which, however, is not continuous over the entire flat structure so that cohesion of the flat structure is ensured at the ends of the flat structure, i.e. where there is no slit.
  • the geometric shape of the material strips or of the geometric shapes formed by the flow openings on the flat structure is essential irrelevant;
  • the surface strips can be structured as strips or the surface structures through straight slots, but all other possible geometrical shapes on material strips or surface structures are also possible, for example also S-shaped strips or slot guides, but also perforations etc.
  • Embodiments of the flat bag are excluded and therefore not part of the invention, in which diffusers in the form of flat structures with elongated flow openings are arranged in the first level directly under the top of the filter bag in the area of the inlet opening, these diffusers being attached on both sides to the top of the bag and their surface is less than 10%, based on the total bag surface, the width of the material strips defined by the slits being defined as ⁇ 50% with respect to the diameter of the inflow opening.
  • the diffuser arranged in level 1 is thus shorter than the total length or width of the flat bag. Both ends of the diffuser in plane 1, designed as a slotted sheet-like structure, are fixed directly to the top of the bag. The diffuser completely covers the inlet opening.
  • the filter bags according to the invention have an excellent dust storage capacity and thus have an increased service life. It can also be observed that blockages in the area of the air inlet of the bag - as is the case with the bags known from the prior art Fig. 3 can often be the case - could be avoided.
  • the material strips are arranged movably to one another; It is also possible for the material strips to be spaced apart from one another or for the flow openings of the flat structures to be dimensioned such that the resulting material strips are spaced apart from one another.
  • the width of the material strips is 2 mm to a maximum of 50% of the width of the top of the bag.
  • Particularly preferred widths of the material strips are in the order of magnitude between 5 and 35% of the width of the bag. The same applies to the arrangement of the elongated flow openings in the flat structures relative to one another, the flow openings determining the width of the stripes.
  • the elongated flow openings of the planar structures are linear.
  • the flow openings can be designed in parallel or meandering or zigzag shape, and spiral lines are also conceivable.
  • the linear, elongated flow openings have different lengths within the flat structure.
  • This embodiment of the invention comes into play when there are at least two flow openings on the sheet-like structure. These flow openings can have different lengths, which leads to improved stability of the diffuser.
  • both diffusers are attached to the bag wall on both sides.
  • both diffusers that is to say those of level 1 and level 2
  • the fixation takes place preferably in the end area of the two diffusers so that they are only connected to the bag wall at certain points and are flexible in the area in between due to the pliable material and can be moved by the inflowing air.
  • the diffusers have approximately the same length and / or width as the top or bottom of the bag.
  • a fixation of the diffusers in this case can then expediently take place in that the ends of the diffusers are introduced between the top and bottom of the filter bag and are fixed together with the top and bottom to form the finished bag.
  • the fixation of the diffusers takes place simultaneously with the gluing or welding step for the production of the filter bag itself. In this respect, this possibility of fixing enables an extremely inexpensive and simple production of the filter bag.
  • the diffusers are narrower and / or shorter than the top or bottom of the bag.
  • the diffusers it is also possible for the diffusers to have a greater length and / or width than the top or bottom of the bag and to be folded.
  • the diffusers are expediently folded when the length of the diffusers is greater than the dimension of the length and / or width of the filter bag.
  • the folding then expediently takes place in a zigzag shape, with the strips of the diffuser partially overlapping one another, for example in the case of a diffuser in the form of strips. In this respect, an increase in the area of attack for the inflowing air is made possible, which leads to a further improvement in the properties of the filter bag.
  • Another embodiment of the present invention provides that the diffusers are designed in the form of strips of material rotated and / or twisted. Here, too, there is an increase in the area of attack for the inflowing air, with the same advantages as those already described for the folded shape of the diffusers.
  • the diffusers are formed in the form of strips of material by filament bundles or bundles of film strips.
  • the material strips themselves are formed from a plurality of filaments or threads or the like.
  • advantages of the present invention result if at least one diffuser is arranged in one plane to at least one diffuser in the next plane in such a way that the material strips and / or the elongated flow openings intersect.
  • the material strips or the arrangements of planar structures of the diffusers in plane 1 and plane 2 do not run parallel to one another in perspective.
  • crossing diffusers are arranged orthogonally to one another, but other crossing angles are also possible intersecting diffusers possible, the intersecting diffusers are thus arranged in an arrangement that deviates from the orthogonal arrangement.
  • At least two diffusers can each be arranged in relation to one another in one plane in such a way that the material strips and / or the elongated flow openings are not arranged parallel to one another.
  • the air flows entering the filter bag can be swirled in a targeted manner.
  • the materials of the pliable diffusers preferably consist of air-permeable materials and / or of air-impermeable materials.
  • Films for example plastic films (e.g. PE, PP), come into consideration as air-impermeable materials.
  • Laminates of air-permeable materials and / or air-impermeable materials provided with flow openings are preferably used as air-permeable materials.
  • the diffusers are connected to the bag wall via an adhesive point and / or weld points.
  • the flat bag is formed by two strips of the filter material welded to one another in the edge area.
  • the flat bag can be designed in any geometric shape, in particular square, hexagonal or octagonal designs are possible.
  • the diffusers are connected to the edge region of the flat bag.
  • the present flat bag according to the invention is a gusset bag.
  • the diffusers are preferably connected to the side gusset of the flat bag.
  • the inside of the top of the filter bag has a film (e.g. a PE film) in the area of the air inlet opening.
  • a film e.g. a PE film
  • This film can, for example, be glued on or welded. In this way, dust deposits can be almost completely avoided during operation in the area of the inlet opening, so that the closing function of the flap is not impaired.
  • the filter bags used in the examples are shown in the figures shown below to illustrate the arrangement of the diffusers inside.
  • the diffusers are arranged on two levels D1 and D2 in the interior of the filter bag, level D1 representing the level facing the top of the filter bag and level D2 representing the level facing the bottom of the filter bag.
  • the bags are viewed in projection with a view of the top of the bag from the bottom of the bag.
  • all diffusers are formed from strips of three-layer nonwoven material.
  • an arrangement of the diffusers "longitudinally” means a vertical arrangement of the diffusers shown in the figures, while “transversely” means a horizontal arrangement of the diffusers within the filter bag. A distinction in this regard is necessary, since the inlet opening is asymmetrical with respect to the center of gravity of the filter bag is arranged.
  • the two lower lines of the tables each show the measured pressure loss in% after the intake of 200 or 400 g DMT standard dust, this value being the measured pressure value after the intake of the respective amount of dust, based on the measured pressure, with the dust filter bag inserted in the vacuum cleaner was determined without prior absorption of dust.
  • comparative examples 1 * dust filter bag without flow straighteners or diffusers, see FIG. 1
  • 2 * filter bag with a continuous fleece layer, see FIG Figure 2
  • a significant improvement in the pressure drop or pressure loss can be observed for all quantities of dust taken up.
  • the dust filter bags according to the invention have a significantly longer service life or dust holding capacity compared to the filter bags according to Comparative Examples 1 * and 2 *.
