Definitions

  • the present invention relates to a block bottom bag for vacuum cleaner, which has in its interior at least one diffuser of strips of material and / or fabrics with elongated flow openings.
  • Such bags are characterized by an excellent dust storage capacity and an extension of the service life.
  • EP 1 787 560 A1 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 U1 and the DE 20 2008 003 248 U1 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 U1 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 may be formed as a continuous strip fixed to two opposite edges of the bag.
  • the DE 20 2007 010 692 U1 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 A1 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 U 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.
  • a block bottom bag having a bag body of single or multi-layer filter material, the two opposite, the bag top, which contains an inlet opening or on which the inlet bottom containing a block bottom is folded back and forming the bottom of the bag Surface and has two folded on the bottom sides of the bag between the surface walls side walls.
  • Another block bottom bag with a closed free end portion and an opposite at least partially closed area and a holding plate is from the DE 103 48 375 A1 known, wherein the bottom of the bag is formed of a plurality of superimposed layers of the bag material.
  • the US 2,848,062 discloses a block bottom bag with an inserted, partially flat, unslotted material layer.
  • a filter bag which has bactericidally formed fingers which are each formed on a strip of material in the interior of the bag.
  • a block bottom bag having a bag front side, a bag rear side and a block bottom which spaces the bag front side and the bag back side to form a bag interior with bag walls made of an air-permeable filter material, the block bottom having an inlet opening for the air to be filtered and inside the block bottom bag at least one diffuser is arranged, which consists of at least two mutually arranged individual material strips and / or sheet-like material structures having elongated flow openings, wherein the at least one diffuser is connected at least one side to the bag wall.
  • a filter bag having a front side, a back and at least three surfaces for generating an inner volume.
  • one of the at least three side surfaces forms the bottom side of the filter bag, while the two remaining side surfaces each connect the outer, the front and the rear bounding edges together, whereby an interior is formed, which defines the volume of the filter bag in the operating state.
  • the a collapsing of the filter bag allows in such a way that a flat contact between the front and the back of the filter bag is made possible.
  • either the bottom surface or the front side of the filter bag has an air inflow opening.
  • SOS self-opening bag
  • stand-up pouches are also referred to as block bottom pouches.
  • the inventively mounted inside the bag diffusers which are formed from strips of material or provided with flow openings fabrics, thereby causing a turbulence of the incoming, loaded with dirt and / or dust particles air.
  • the service life of the bag can be significantly extended.
  • the diffuser of a pliable material is formed from at least two mutually arranged strips of material; but it can 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;
  • 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.
  • the filter bags have an excellent dust storage capacity and thus have an increased service life. It can also be observed that blockages in the region of the air inlet of the bag - as is often the case with the bags known from the prior art - 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 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.
  • the elongated flow openings of the fabrics are linear.
  • the flow openings may be parallel or meander-shaped or zigzag-shaped, and 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.
  • the at least one diffuser is attached to both sides of the bag wall.
  • the diffuser is thus fixed to the front of the bag or the back 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.
  • the diffuser in about the same length and / or Has width as the bag front and / or back.
  • a fixation of the diffuser in this case can then conveniently be done by the ends of the diffuser are introduced between the front and back of the filter bag and are fixed together with the front and back to 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.
  • the diffuser is narrower and / or shorter than the bag front and / or back.
  • the diffuser has a greater length and / or width than the bag front and / or back side 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.
  • the diffuser in the form of strips of material is 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.
  • At least two diffusers can each be arranged in such a way in each case in the intermediate plane that the strips of material and / or the elongated flow openings are not arranged parallel to one another, for example orthogonally, but also in deviating arrangements.
  • the entering into the filter bag air streams can swirl targeted.
  • the limp materials of the diffuser preferably consist of air-permeable materials and / or of air-impermeable materials.
  • air-impermeable materials are films, for example plastic films (for example PE or PP).
  • air-permeable materials laminates of air-permeable materials and / or flow-apertured air-impermeable materials are preferably used.
  • the composite materials is a construction of a layer of polypropylene spunbonded fabric of about 15 g / m 2 , a layer of crimped polypropylene staple fibers of about 100 g / m 2 and a second final spunbonded layer of again 15 g / m 2 .
  • the cohesion of the composite is done via welding points that connect all layers together.
  • the diffuser is connected to the bag wall via a splice and / or welds.
