Definitions

  • the present invention relates to a flat bag for vacuum cleaner, which has in its interior at least two diffusers of strips of material and / or fabrics 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 distributor in the form of attached in the region of the inlet opening of the filter bag boxes or strips of material, which are able to divide the incoming air flow into partial streams and to divert.
  • 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 For example, combinations of two flow distributors with a spacer are known.
  • a filter bag that includes a bag having an interior partitioned into at least two chambers.
  • the subdivision is by a partition defined at three side edges, with a transition between the first and second chambers formed at the fourth side edge.
  • the partition wall is welded to the filter layers only at one side edge for the entire length and is welded at the opposite side to a strip at 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 is to 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 formed 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 extends between the two filter walls, a filling layer of fiber or yarn material, which is connected to both filter walls and is pulled apart during deployment of the bag so that a net-like structure is formed in the bag.
  • Another air distributor is from the DE 10 2006 051 117 known.
  • at least two layers of material are arranged one above the other between the bag walls, the layers having a smaller extent than the two bag walls in a first area direction and having the same extent as the bag walls in the area direction orthogonal to the first area direction.
  • materials microfiber fleece or paper are called.
  • the DE 20 2006 016 304 discloses a bag with at least one guide element, by means of which the incoming air flow is deflectable.
  • the guide element is fixed adjacent to the inlet opening.
  • a flat bag according to the preamble of claim 1 is in DE 20 2008 003 248 U disclosed.
  • a Miele bag already on the market has an arrangement of a deflector mounted just below the inlet opening.
  • This deflection device consists of a sheet 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 redirect the air flow sucked in through the inlet opening directly in the region of the inlet opening.
  • This deflection device is designed such that, due to a predetermined length or area, it is welded directly to the bag wall at a distance from the inlet opening. The area of this deflector is therefore below 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 dimensioned dimensions of the first deflecting device (SR1), blockages of the bag may occur due to dust accumulated between the inlet opening and the deflecting device, so that the bag becomes unusable.
  • SR1 first deflecting device
  • a flat bag for a vacuum cleaner with a bag top and a bottom bag is provided, the bag walls are formed from an air-permeable filter material and wherein an inlet opening for the air to be filtered is introduced in the bag top, wherein in the interior of the flat bag below the top of the bag in a first Level and between the first level and the bag bottom is provided in at least one other level in each level at least one diffuser, the diffuser consists of at least two mutually arranged strips of material and / or fabrics 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 sheets with elongated flow openings arranged in the first plane in the region of the inlet opening and on both sides of the Bag top are attached with an area of ⁇ 10%, based on the entire bag surface, the width of the strip of material by the diameter of the inflow opening is defined ⁇ 50% are excluded.
  • the diffusers which are formed from strips of material or structures provided with flow openings, thereby cause turbulence of the inflowing, laden with dirt and / or dust particles Air.
  • the service life of the bag can be significantly extended.
  • the flat bag are arranged in the diffuser in the form of sheets with elongated flow openings in the first level directly under the filter bag top in the region of the inlet opening, these diffusers are attached to both sides of the bag top and the surface thereof is less than 10%, based on the total bag surface, with the width of the strips of material defined by the slits being defined as ⁇ 50% of the diameter of the inlet opening.
  • this recessed embodiment of the flat bag thus arranged in level 1 diffuser is shorter than the total length or width of the flat bag. Both ends of the diffuser formed as a slit sheet in level 1 are fixed directly to the bag top. 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 is also observed that blockages in the region of the air inlet of the bag - as in the known from the prior art bags according to Fig. 3 often the case could be avoided.
  • the strips of material are arranged movably relative to one another; It is also possible that the material strips are spaced apart from each other or that the flow openings of the fabrics are dimensioned so that the resulting strips of material are spaced from each other.
  • the width of the material strips is 2 mm to a maximum of 50% of the width of the bag top.
  • Particularly preferred widths of the material strips are in the range between 5 and 35% of the width of the bag. The same applies to the arrangement of the elongate flow openings in the fabrics to each other, wherein the flow openings determine the strip width.
  • the elongated flow openings of the fabrics are linear.
  • the flow openings may be parallel or meander-shaped or zigzag-shaped, furthermore, spiral-shaped linear guides are also conceivable.
  • the line-shaped, elongated flow openings have different lengths within the fabric. This embodiment of the invention comes into play when at least two flow openings are present on the sheet. These flow openings can have different lengths, resulting in improved stability of the diffuser.
  • both diffusers are attached to both sides of the bag wall.
  • both diffusers ie the level 1 and the level 2 respectively fixed to the bag top or bottom bag.
  • the fixation is preferably carried out respectively in the end region of the two diffusers, so that they are only selectively connected to the bag wall and are flexible in the intermediate region due to the pliable material and can be moved by the incoming air.
  • Part of the invention is also that the diffusers have approximately the same length and / or width as the Beutelober- or -unterseite.
  • a fixation of the diffusers in this case can then be conveniently carried out by the fact 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 of the finished bag.
  • the fixation of the diffusers is thus carried out simultaneously with the adhesive or welding step for the production of the filter bag itself. Insofar, this possibility of fixation allows an extremely cost-effective and simple production of the filter bag.
  • the diffusers are narrower and / or shorter than the bag top and bottom.
  • the diffusers have a greater length and / or width as the Beutelober- or -unterseite and folded.
  • the folding of the diffusers is expediently carried out when the length of the diffusers is greater than the dimension of the length and / or width of the filter bag.
  • the folding is then expediently carried out in a zigzag form, wherein, for example, in the case of a diffuser in strip form, a partial overlapping of the strips of the diffuser takes place one above the other. In this respect, an increase of the attack surface for the incoming air is made possible, which leads to a further improvement of the properties of the filter bag.
  • a further embodiment of the present invention provides that the diffusers are formed in the form of strips of material and / or twisted. Again, there is an increase in the attack surface for the incoming air, with the same advantages come into play, as they have already been described in the folded form of the diffusers.
  • the diffusers in the form of strips of material are formed by filament bundles or bundles of film strips.
  • the strips of material themselves are formed from a plurality of filaments or threads or the like.
  • advantages of the present invention arise when at least one diffuser is arranged in a plane to at least one diffuser in the next plane so that the strips of material and / or the elongated flow openings intersect.
  • the material strips or the arrangements of flat structures of the diffusers in the plane 1 and the plane 2 do not extend parallel to each other in perspective.
  • the intersecting diffusers are arranged orthogonal to each other, but other crossing angles are the Crossing diffusers possible, so the crossing diffusers are arranged in a different from the orthogonal arrangement.
  • At least two diffusers can each be arranged in a plane relative to one another such that the strips of material and / or the elongate flow openings are not arranged parallel to one another.
  • the air streams entering the filter bag can be specifically swirled.
  • the materials of the limp diffusers preferably consist of air-permeable materials and / or of air-impermeable materials.
  • films for example plastic films (for example PE, PP), are suitable as air-impermeable materials.
  • air-permeable materials laminates of air-permeable materials and / or flow-apertured air-impermeable materials are preferably used.
  • the diffusers are connected to the bag wall via a splice and / or welds.
  • the flat bag is formed by two webs welded together in the edge region from the filter material.
  • the flat bag can be designed in any geometric shapes, in particular here are quadrangular, hexagonal or octagonal configurations in question.
  • the diffusers are connected to the edge region of the flat bag.
  • the present flat bag according to the invention is a gusseted bag.
  • the diffusers are preferably connected to the side fold of the flat bag.
  • the inside of the filter bag top side has a foil (for example a PE foil) in the area of the air inlet opening.
  • This film may be glued or welded, for example.
  • the filter bags used in the examples are shown to illustrate the arrangement of the diffusers inside in the figures shown below.
  • the diffusers are arranged on two levels D1 and D2 in the interior of the filter bag, wherein the plane D1 represents the filter bag top facing plane and the plane D2 represents the filter bag bottom facing plane.
  • the bags are viewed in projection from the bottom of the bag, looking at the top of the bag.
  • all diffusers are formed from strips of a three layer nonwoven material.
  • an arrangement of the diffusers means "longitudinally” a vertical arrangement of the diffusers shown in the figures, while “transverse” means a horizontal arrangement of the diffusers within the filter bag. A distinction in this regard is necessary because the inlet opening is asymmetrical with respect to the center of gravity the filter bag is arranged.
  • filter bag type GN from Miele
  • DMT standard dust - type 8 50-400 g, each in 50 g interval steps.
  • the two lower lines of the tables each show the measured pressure loss in% after uptake of 200 or 400 g of DMT standard dust, this value being the measured pressure value after the respective amount of dust, based on the measured pressure, with the dust filter bag in the vacuum cleaner was determined without previous recording of dust.
  • Comparative Examples 1 * dust filter bag without flow straightener or diffusers, see FIG. 1
  • 2 * Filter bag with continuous fleece layer, see FIG. 2
  • a significant improvement in the pressure drop or pressure loss can be observed for all recorded amounts of dust.
  • the dust filter bags according to the invention have a significantly increased service life or dust absorption capacity compared to the filter bags according to Comparative Examples 1 * and 2 *.
  • FIGS. 22 and 23 The basic structure of such filter bag is in the FIGS. 22 and 23 indicated, in FIG. 22 the basic dimensions of this bag type are given.
  • the bag has a characteristic shape and may have in its interior several levels of diffusers.
  • FIGS. 22 and 23 In each case 2 levels of diffusers are shown: In Fig. 22 is in level D1 a longitudinal diffuser (3 x 22 mm) attached and in level D2 a transverse diffuser (10 x 11 mm).
  • the diffusers are arranged in two levels D1 and D2, and here as in the FIGS. 1 to 19 a viewing takes place from the bottom of the bag to the top of the bag.
  • the arranged in the plane D1 diffusers are facing the bag top, while lying in the plane D2 diffusers facing the bottom of the bag.
