Such flat bags are characterized by an excellent dust storage capacity and an extension of the service life.

Description

    Flat bag for vacuum cleaner
  • The present invention relates to a flat bag for vacuum cleaners, which has in its interior at least one forming an intermediate level diffuser of strips of material and / or sheet with elongated flow openings. Such flat bags are characterized by an excellent dust storage capacity and an extension of the service life.
  • The increase of the dust storage capacity - ie extension of the service life (service life) - of a vacuum cleaner filter bag is in addition to the improved separation efficiency (particle retention) an essential goal in the development of filter bags.
  • This can be achieved by innovative bag materials or by the incorporation of the air flow in the filter bag influencing material surfaces. This is what the EP 0 960 645 and the EP 1 795 247 Non-woven materials for vacuum cleaner bags with particularly good dust storage capacity.
  • 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. In the EP 1 804 635 The idea is 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 For example, combinations of two flow distributors with a spacer are known.
  • From the DE 20 2006 016 303 For example, a filter bag is known that includes a bag having an interior partitioned into at least two chambers. In one embodiment, 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. In another embodiment, 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. In this case, dust is to be stored between the at least two layers of the filter insert. For this purpose, the upper of the two layers can be perforated or slotted. The filter insert may be formed as a continuous strip which is fixed to 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.
  • From the DE 20 2006 019 108 is known a dust filter bag with an attached inside Stauwandstück. This stowage wall piece is fastened 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 retaining wall piece is fastened at a distance from the bag seam and does not bear against the rear bag wall under the pressure of the air flow.
  • Another air distributor is from the DE 10 2006 051 117 known. In this case, 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. As materials microfiber fleece or paper are called.
  • The DE 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 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, however, 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. In addition, this vacuum cleaner bag still has a second level of flow straighteners.
  • All aforementioned vacuum cleaner bags, however, have in common that the inflowing dirt particles are distributed inadequately, so that there is premature clogging of the vacuum cleaner bag, which ultimately leads to a reduced dust storage capacity and a significantly inadequate service life of the vacuum cleaner bag.
  • Based on this, it was an object of the present invention to provide a vacuum cleaner filter bag which has an increased dust storage capacity and thus an extension of the service life (service life). guaranteed. In addition, a blockage of the opening should be prevented inside the bag.
  • This object is achieved with respect to the flat bag for a vacuum cleaner with the features of claim 1, wherein the dependent claims represent advantageous developments.
  • According to the invention, a flat bag having a bag top side and a bottom side of the bag, the bag walls of which are made of an air-permeable filter material and wherein an inlet opening for the air to be filtered is introduced in the bag top, is provided in which at least inside the flat bag between the top side of the bag and the bottom side of the bag a diffuser forming an intermediate level is arranged which consists of at least two individual material strips arranged relative to one another and / or of flat material structures which have elongated flow openings, the at least one diffuser being connected to the bag wall on at least one side.
  • The diffusers, which are formed from strips of material or structures provided with flow openings, thereby cause turbulence of the incoming air laden with dirt and / or dust particles. Thus, surprisingly, the service life of the bag can be significantly extended.
  • Thus, the flat bags according to the present invention include at least one diffuser in an intermediate plane for swirling the sucked-in dust particles. According to the invention, this intermediate plane is understood to mean a curved or non-curved surface which forms between the wall of the bag Bag top and bottom is arranged. The intermediate plane in the sense of the invention is thus defined by the arrangement of the diffuser in the interior of the filter bag by connecting the diffuser at least 1 place of the bag wall.
  • The diffuser of a limp material is formed either of at least two mutually arranged strips of material, but may also consist of fabrics that have flow openings in the sense of slots within these fabrics. Such fabrics thus have at least one slot or a transection, which is not pronounced throughout the entire sheet, so that at the ends of the sheet, ie where there is no slitting, a cohesion of the fabric is ensured. The geometric shape of the strips of material or of the geometric shapes formed by the flow openings on the sheet is substantially irrelevant in this case; Thus, for example, the surface strips can be structured as strips or the flat structures through straight slots, but all other possible geometric shapes on material strips or flat structures are also possible, for example also s-shaped strips or slot guides, but also through holes etc.
  • Preferred embodiments of the flat bag, wherein the diffuser is arranged in the form of sheets with elongated flow openings in the first plane directly under the filter bag top in the region of the inlet opening, this diffuser is attached to both sides of the bag top and its area is less than 10% on the entire bag surface, which is the width the material strip defined by the slits is ± 50% defined with respect to the diameter of the inflow opening, except. In this preferred recessed embodiment of the flat bag thus the diffuser is shorter than the total length or width of the flat bag. Both ends of the slit formed as a diffuser are fixed directly to the bag top. The diffuser completely covers the inlet opening.
  • Surprisingly, it has been found that the filter bags 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.
  • In an advantageous embodiment of the invention, 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.
  • It is further preferred that 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 bag width. The same applies to the arrangement of the elongate flow openings in the fabrics to each other, wherein the flow openings define the strip width.
  • It is also advantageous if the elongated flow openings of the fabrics are linear. However, virtually any geometric shapes are possible for the elongated flow openings, for example, the flow openings may be parallel or meander-shaped or zigzag-shaped, and spiral-shaped linear guides are also conceivable.
  • In a further advantageous embodiment, 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.
  • It is also preferred that the at least one diffuser is attached to both sides of the bag wall. In this embodiment, the diffuser is thus fixed in each case to the bag top side or bottom side of the bag. The fixation is preferably carried out in each case in the end region of the diffuser, so that it is only selectively connected to the bag wall and in the intermediate region due to the pliable material is flexible and can be moved by the incoming air.
  • It is also advantageous if the diffuser has approximately the same length and / or width as the Beutelober- or -unterseite. A fixation of the diffuser in this case can then be conveniently carried out by introducing the ends of the diffuser between the top and bottom of the filter bag be fixed together with the top and bottom of the finished bag. The fixation of the diffuser is thus carried out simultaneously with the bonding 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.
  • However, as an alternative embodiment, it is also possible that the diffuser is narrower and / or shorter than the Beutelober- or -unterseite. Here it is also possible that the diffuser has a greater length and / or width than the bag top or - underside and is present folded. The folding of the diffuser is expediently carried out when the length of the diffuser 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 diffuser is designed 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 shape of the diffuser.
  • It is also preferred that the diffuser in the form of strips of material is formed by filament bundles or bundles of film strips. In this embodiment For example, the strips of material themselves are formed from a plurality of filaments or threads or the like.
  • Likewise, in each case in the intermediate plane, at least two diffusers can each be arranged relative to one another so that the strips of material and / or the elongated flow openings are not parallel, e.g. orthogonal, but also in deviating arrangements, are arranged to each other. With such an embodiment, the air streams entering the filter bag can be specifically swirled.
  • The limp materials of the diffuser preferably consist of air-permeable materials and / or of air-impermeable materials. Particularly suitable as air-impermeable materials are films, for example plastic films (for example PE or PP). As air-permeable materials, laminates of air-permeable materials and / or flow-apertured air-impermeable materials are preferably used.
  • It is furthermore preferred if the diffuser is connected to the bag wall via a splice and / or welds.
  • In a further preferred embodiment, 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.
  • It is also preferred if the diffuser is connected to the edge region of the flat bag.
  • In particular, the present flat bag according to the invention is a gusseted bag. In this case, the diffuser is preferably connected to the side fold of the flat bag.
  • Further advantages result if 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. As a result, dust deposits during operation in the area of the inlet opening can be almost completely avoided, so that the closing function of the flap closing the inlet opening is not impaired.
  • The filter bags used in the examples are shown to illustrate the arrangement of the diffusers inside in the figures shown below. The bags are viewed in projection from the bottom of the bag, looking at the top of the bag. Unless otherwise stated, all diffusers are formed from strips of a three layer nonwoven material. In the following figure designations, 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 arranged asymmetrically with respect to the center of gravity of the filter bag.

    • FIG. 20 shows a filter bag according to the invention with a transversely disposed diffuser (11 x 22 mm) (Example 20).
    • FIG. 21 shows a filter bag according to the invention with a transverse diffuser (24 x 11 mm) (Example 21).
  • The in the FIGS. 1 to 21 shown filter bag (type GN from Miele) were measured in a series of experiments (carried out with a vacuum cleaner from Miele, type 5210) with defined amounts of DMT standard dust type 8 (50-400 g, each in 50 g interval steps). Reference is made to DIN EN-ISO 60312. The measured values are given for the filter bags in Table 1. The two lower lines of the table show in each case 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 has been measured in relation to the measured pressure with the dust filter bag in the vacuum cleaner was determined without previous recording of dust. Compared with Comparative Examples 1 * (dust filter bag without flow straightener or diffusers, see FIG. 1) and 2 * (Filter bag with continuous fleece layer, see FIG. 2 ), can be a significant improvement in pressure drop or pressure loss at all Observe recorded dust levels. In this respect, 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 *. Compared with the filter bag of Comparative Example 3 * known from the prior art (see FIG. 3 ) can largely be found as well improved test results in terms of dust storage capacity and service life, while some filter bags according to the invention in terms of dust holding capacity and service life of the filter bag according to Comparative Example 3 * are almost equal. However, compared to the filter bag according to Comparative Example 3 *, the filter bags according to the invention always have the advantage that blockages in the region of the inlet opening are provided by the very short flow straightener SR1 of the filter bag (see FIG. 3 ) can be almost completely avoided.
  • In FIG. 22 selected test results are compared with the filter bags according to the invention the filter bags according to Comparative Examples 1 * to 3 * compared. In each case, a comparison of the measured values obtained with Comparative Examples 1 * to 3 * takes place in the diagram. It can clearly be seen that the filter bags according to the invention are clearly superior to the filter bags according to Comparative Examples 1 * and 2 * with regard to the pressure drop at a previously defined absorbed amount of dust, while with respect to the filter bag according to Comparative Example 3 * even results or slight improvements can be observed. However, it is advantageous in the case of the vacuum cleaner filter bags according to the invention with respect to those of the comparative example 3 * that the filter bags according to the invention are less congestive tend in the area of the inflow opening.
