Definitions

  • the invention relates to devices for vacuuming with a vacuum cleaner and a filter bag, which is designed as a nonwoven filter bag, disposable filter bag and flat bag with surface wrinkles.
  • Filter bags in the form of non-woven disposable flat bags are the filter bags most commonly used today.
  • the advantage of non-woven bags is the significantly higher dust absorption capacity of the filter bag with higher separation efficiency and longer service life.
  • the flat bag form is the most common form for nonwoven bags since bags of this shape are very easy to manufacture. Because in contrast to the paper filter material used in filter bags made of paper, nonwoven filter material is very difficult to permanently fold because of the high resilience, so that the production of more complex bag shapes, such as block bottom bags or other bottom bag forms, is very complicated and expensive.
  • a flat bag in the sense of the present invention is understood to mean filter bags whose filter bag wall is formed from two individual layers of filter material with the same area such that the two individual layers are connected to each other only at their peripheral edges (the term same area does not exclude, of course, that the two Individual layers differ from one another in that one of the layers has an inlet opening).
  • connection of the individual layers can be realized by a weld or adhesive seam along the entire circumference of the two individual layers; but it can also be formed by a single layer of filter material is folded around one of its symmetry axes and the remaining open peripheral edges of the resulting two partial layers are welded or glued (so-called tubular bag). With such a production three welding or gluing seams are therefore necessary. Two of these seams then form the filter bag edge, the third weld can also form a filter bag edge or lie in one of the filter bag walls.
  • a single layer of filter material per se may consist of one or more layers, which may be laminated, for example.
  • Flat bags in the sense of the present invention may also have so-called gussets. These side folds can be completely unfoldable.
  • a flat bag with such gussets is shown, for example, in DE 20 2005 000 917 U1 (see FIG. 1 there with folded side folds and FIG. 3 with folded side folds).
  • the gussets may be welded to portions of the peripheral edge.
  • Such a flat bag is shown in DE 10 2008 006 769 A1 (see there in particular Fig. 1).
  • flat bag is 2-dimensional structures immediately after production, ie before use have an inner volume which is substantially equal to zero.
  • a filter bag having an internal volume that is substantially zero is not necessarily a flat bag in the sense of the present invention.
  • bag shapes that have a bottom as shown for example in DE 20 2005 016 309 U1 or DE 20 2009 004 433 U1, are not flat bags, since they are not made of two individual layers with the same area, which are interconnected only at their peripheral edges , consist.
  • bag shapes which are already 3-dimensional structures after production and thus have a non-zero internal volume, as described, for example, in WO 00/00269 (see FIGS. 27 and 28). and DE 10 2007 060 748 (see there in particular Fig. 9) are shown, are not flat bags in the sense of the present invention.
  • a nonwoven filter bag in the sense of the present invention comprises a nonwoven filter material.
  • a nonwoven fabric material a dry-laid or wet-laid nonwoven fabric or an extrusion fabric, in particular, a melt-spun microfiber spunbond fabric (meltblown nonwoven fabric) or filament spunbond fabric (spunbond) can be used. There may also be additional nanofiber layers.
  • a conventional (filter) paper is therefore not a nonwoven.
  • the nonwoven fabric may comprise staple fibers or continuous fibers. Manufacturing technology can also provide several layers of staple fibers or continuous fibers, which are solidified to exactly one layer of nonwoven fabric.
  • the filter material may also be a laminate of multiple nonwoven layers, such as filament tow and meltblown (SMS, SMMS or SnxMS). Such a laminate may be laminated or calendered by means of a hot melt adhesive.
  • the layer of Meltbiownvie may be creped.
  • nonwoven is used according to the definition according to ISO standard ISO 9092: 1988 or standard EN 29092.
  • nonwoven fabric or nonwoven and nonwoven fabric in the field of production of nonwovens are delimited and also as defined in the following
  • the loose or loose and still unconnected fibers and / or filaments are referred to as nonwoven or nonwoven fabric (Web) formed by a so-called non-woven binding step of such a nonwoven fabric
  • Web nonwoven or nonwoven fabric
  • a nonwoven fabric that has sufficient strength to be wound up into rolls in other words, a nonwoven fabric becomes self-supporting by solidification.
  • the filter bag wall has at least one surface fold. How such surface wrinkles can be formed results, for example, from European Patent Application 10163463.2 (see there in particular FIGS. 10a and 10b or FIGS. 11a and 11b). If the filter bag wall comprises several surface folds, then this material is also referred to as a pleated filter material. Such pleated filter bag walls are shown in European patent application 10002964.4.
  • Fig. 1 and Fig. 2 show a filter bag in cross section with a wall, each having two surface folds. By such surface wrinkles, the filter surface of the filter bag is increased, resulting in a higher dust holding capacity of the filter bag with higher separation efficiency and longer life results (each opposite a filter bag with the same outer dimensions without surface wrinkles).
  • a filter bag 1 with a filter bag wall 10 which has two surface folds 11 in the form of so-called dovetail folds shown.
  • the filter bag is shown here in cross section through the filter bag center.
  • the longitudinal axes of the surface wrinkles thus run in a plane which in turn is perpendicular to the plane of the drawing, and the surface wrinkles go over at their longitudinal ends in the plane parallel to the drawing plane and lying in front of and behind the plane of the weld seams of the filter bag.
  • the filter bag is shown here in a state in which the surface wrinkles are already unfolded somewhat.
  • Each dovetail fold 11 has portions 11a located in the surface of the filter bag wall 12 and portions 11b protruding beyond the surface of the filter bag wall 12. These areas 11b are not unfolded during the first insertion of the filter bag in the vacuum cleaner.
  • FIG. 2 shows a filter bag 2 with a filter bag wall 20, which has two surface folds 21 in the form of so-called triangular folds.
  • the filter bag is also shown here in cross section through the filter bag center.
  • the longitudinal axes of the surface wrinkles thus run in a plane which in turn is perpendicular to the plane of the drawing, and the surface wrinkles go at their longitudinal ends in the plane parallel to the drawing plane and lying before and behind the plane of the weld seams of the filter bag.
  • the filter bag is also shown here in a state in which the surface wrinkles are already unfolded.
  • Each triangular fold 21 has portions 21a located in the surface of the filter bag wall 22 and portions 21b protruding beyond the surface of the filter bag wall 22. These areas 21 b are not unfolded in the first time the filter bag in the vacuum cleaner device.
  • the second filter bag wall of the filter bag shown in Fig. 1 and Fig. 2 has no surface folds.
  • this second filter bag wall may also have one or more surface folds.
  • surface folds with other shapes are also possible.
  • the fact that the surface folds in the embodiments according to FIG. 1 and FIG. 2 are perpendicular to a bag edge is not to be understood as a restriction.
  • the surface wrinkles may also be at an angle to the edges of the bag.
  • Vacuum cleaners of the prior art have filter bag containment spaces with rigid walls. For a filter bag to develop its filtering effect, these walls have holding devices in the form of ribs or rib-shaped sections, which prevent the filter bag with its filter surface against the wall of the filter bag receiving space and thus the effective filter area is reduced.
  • the present invention seeks to improve the known from the prior art device for vacuuming with a vacuum cleaner and a filter bag such that the dust holding capacity of the filter bag is further increased with higher separation efficiency and longer life.
  • a device for vacuuming with a vacuum cleaner and a filter bag according to claim 1, ie by a device in which the filter bag is formed as a non-woven filter bag, disposable filter bag and flat bag with a first filter bag wall and with a second filter bag wall, in which the filter bag has at least one surface fold, each surface fold having areas located in the surface of the filter bag wall and having areas that protrude beyond the surface of the filter bag wall and are deployable in the suction mode in which the vacuum cleaner has a rigid wall filter bag receiving space at least a first spacer means is provided on the walls of the filter bag receiving space such that it beabs the areas of at least one surface fold located in the surface of the filter bag wall from the wall of the filter bag receiving space tandet, and at least one second spacer means is provided so as to keep the deployed portions of the at least one surface fold spaced from the wall of the filter bag containment space.
  • the surface fold is able to do so unfold that the majority of the surface of the surface fold forming filter material is vorströmbar.
  • This increases the effective filter area of the filter bag (as opposed to use in a conventional vacuum cleaner) so that the dust holding capacity of the filter bag can be further increased with higher separation efficiency and longer service life over this conventional device.
  • the height of the first and / or the second spacer means relative to the wall of the filter bag receiving space in a range of 5 mm to 60 mm, preferably from 10 mm to 30 mm lie.
  • each first and each second spacer means may be formed as a web, web-shaped section, bracket, bow-shaped section, rib, rib-shaped section and / or pin.
  • each first and each second spacer means may be formed integrally with the wall of the filter bag receiving space.
  • the filter bag accommodating space of the vacuum cleaner apparatus can be manufactured by an injection molding method. This ensures a simple and inexpensive production of the filter bag receiving space.
  • all the first and all second spacer means may be formed as a cage-shaped insert provided in the filter bag accommodation space.
  • the cage-shaped insert can be removed from the filter bag receiving space and made reusable in the filter bag receiving space.
  • the filter bag may have a plurality, preferably three to seven surface folds in the first layer of the filter bag wall and / or several, preferably three to seven surface folds in the second layer of the filter bag wall.
  • FIG. 1 shows a filter bag according to the prior art with two surface folds in the form of dovetail folds
  • Figure 2 shows a filter bag according to the prior art with two surface folds in the form of triangular folds.
  • Fig. 3 shows a first embodiment of the present invention
  • Fig. 4 shows a second embodiment of the present invention.

  • Fig. 3 the filter bag is shown with fully unfolded surface folds 31.
  • the areas 31 a which lie in the surface of the filter bag wall 32 are held by a first spacer means 35 from the wall of the filter bag receiving space 33 spaced.
  • the areas 31 b, which protrude beyond the surface of the filter bag wall 32 are held by second spacer means 36 from the wall of the filter bag receiving space 33 spaced.
  • the height of the first and second spacer means depends on both the size of the surface fold and the shape of the filter bag receiving space. If the filter bag accommodating space has a shape similar to the shape of the filter bag in operation as in the embodiment of Fig. 3, the spacer means may be made smaller than in a case where the filter bag space is substantially the same as that in the prior art Shape of a cuboid has. In the latter case, in particular Especially when the filter bag has a plurality of surface wrinkles, the first spacer means for the different surface wrinkles also have a different size. The same applies to the second spacer devices (see the embodiment discussed with reference to FIG. 4).
  • the first and second spacer means are presently configured as web-shaped sections which extend in sections along the surface fold.
  • the first and second spacer means are integrally formed with the wall of the filter bag accommodating space 33. This allows a simple production of the filter bag receiving space, for example by an injection molding process.
  • first and second spacer devices may also be formed as ribs, rib-shaped section and / or pin.
  • a second embodiment of the present invention is shown. This embodiment is particularly suitable for a filter bag with triangular folds, as shown in Fig. 2, suitable.
  • the filter bag is shown with fully unfolded surface folds 41.
  • the areas 41a which lie in the surface of the filter bag wall 42 are kept at a distance from the wall of the filter bag receiving space by a first spacer means 45.
  • the areas 41 b, which protrude beyond the surface of the filter bag wall 42 are held by second spacer means 46 from the wall of the filter bag receiving space spaced.
  • first and second spacers are the same as those of the first embodiment.
  • the first and second spacer means are provided in the form of a cage.
  • the outer shape of this cage is defined by the second spacing means, which define the areas of the surface folds that extend beyond the surface of the filter bag wall.
  • all the rods forming the second spacer devices extend. substantially parallel to each other and substantially parallel to the surface folds of the filter bags when properly inserted into the cage.
  • Also substantially parallel to these bars are the bars which form the first spacing means. These bars resemble the shape of the surfaces of the filter bag and thus extend into the interior of the cage formed by the second spacing means.
  • cage bars which extend at an angle, in particular perpendicular, to the bars which form the first and the second spacing means. Such angled bars serve to stabilize certain areas of the filter bag, for example the area of the inflow opening.
