Definitions

  • the invention relates to a vacuum cleaner filter bag comprising an inlet opening, a filter bag material having an inner layer made of material at least in the region of the inlet opening, and a holding plate arranged on the filter bag outside in the region of the inlet opening, which can be attached to a holding device of a vacuum cleaner for holding the vacuum cleaner filter bag a closure device, in particular a closure flap, is provided for closing the inlet opening.
  • Vacuum cleaner filter bags are placed inside the housing of a vacuum cleaner to pick up the sucked dust.
  • vacuum cleaner filter bags For mounting the vacuum cleaner filter bag in the interior of the housing, vacuum cleaner filter bags each comprise a holding plate, via which the vacuum cleaner filter bag can be fixed to a holding device provided in the interior of the housing.
  • Such vacuum cleaner filter bags and holding plates have an inlet opening through which an air flow with Staubpartikein can enter into the interior of the filter bag. For various reasons, it is desirable that this inlet opening be closed. On the one hand, it can be prevented by a closed inlet opening when disposing of a filled vacuum cleaner filter bag that emerges in the filter bag accumulated dust. Furthermore, some vacuum cleaner filter bags contain loose particles, for example, for odor absorption. In order to prevent falling out of these particles, also a closure of the inlet opening is advantageous.
  • a dust filter bag is known, wherein a stowage wall piece is arranged on the inside of the bag facing the rear side of the front bag wall.
  • the filter cake often protrudes into the pivotal region of the closure flap, so that when closing the flap, more or less material is clamped and thereby obstructing the closure function, i. the flap does not completely close the vacuum cleaner filter bag.
  • the formation of the filter cake is in this case particularly strong in low-flow areas, for example in the region of the hinge of the flap to observe.
  • a vacuum cleaner filter bag comprising an inlet opening, a filter bag material having an inner layer of nonwoven material at least in the region of the inlet opening, and a holding plate arranged on the filter bag outside in the region of the inlet opening, which can be attached to a holding device of a vacuum cleaner for holding the vacuum cleaner filter bag and in which a closure device is provided for closing the inlet opening, wherein the nonwoven material in the region of the inlet opening has a surface which is provided such that the formation of a filter cake on this surface is avoided.
  • a surface of the nonwoven material on which no filter cake can form ie a free-lying surface, hereinafter also referred to as open space
  • a free-lying surface hereinafter also referred to as open space
  • the surface (free surface) can be completely or partially formed by a film, in particular a self-adhesive coated film. This is a particularly effective way to build to avoid a filter cake.
  • the attachment of the film can be done for example by gluing (coated film) or welding.
  • the surface (free surface) may be completely or partially formed by a paper, a cardboard or a cardboard, in particular a self-adhesive coated paper, a self-adhesive coated cardboard or a self-adhesive coated cardboard.
  • a paper, a cardboard or a cardboard in particular a self-adhesive coated paper, a self-adhesive coated cardboard or a self-adhesive coated cardboard.
  • the surface (free surface) may be completely or partially formed by compacted nonwoven material.
  • the surface of the nonwoven fabric can be given a sheet-like character.
  • This compacting can be done by ultrasonic welding or thermal welding. This provides another alternative.
  • the surface (free surface) can be formed completely or partially by a liquid which dries during film formation. As a result, the nonwoven fabric is smoothed on the surface (free surface). This provides another alternative.
  • the surface (free surface) may be in the form of a strip running around the inlet opening, preferably a ring.
  • the circumferential strip may be open or closed, so that in the latter case, the inlet opening is completely surrounded by the strip (ring).
  • Said strip or ring may be made different widths in a partial areas. As a result, it can be optimally adapted to the respective conditions.
  • the strip may be annular, which offers a simple way of producing the vacuum cleaner filter bag according to the invention.
  • the strip in the two alternatives mentioned above may have a width in the range of 5 mm to 150 mm, preferably 10 mm to 50 mm.
  • the minimum width results from the typical extension of a filter cake of house dust beyond an edge.
  • the maximum width is only limited by the fact that the loss of effective filter area should be kept as low as possible.
  • a relatively large width may be necessary when the filler opening is seated close to an edge of the filter bag and the filter cake grows from the side surface into the pivotal region of the flap.
  • the closure device may comprise a pivotable closure element, whereby an effective closure mechanism is provided.
  • the closure element can be arranged in the filter bag interior in the region of the inlet opening.
  • the above-mentioned film may continue to be useful as a sealing element between the filter bag and holding device of the vacuum cleaner, wherein the film may consist in particular of a thermoplastic elastomer.
  • the film may additionally also be a sealing element to the stub out (sole or additional seal between the vacuum cleaner and filter bag).
  • the vacuum cleaner filter bag according to the invention can also be the compacted nonwoven material as a sealing element between the filter bag and holding device of the vacuum cleaner be usable. In the two last developments, no separate seal is needed.
  • said film may be antistatic, which additionally prevents deposition of fibers and dust on the surface (open space).
  • FIG. 1 shows a schematic plan view (opposite to the opening direction) on a holding plate 2 of a vacuum cleaner filter bag according to the invention.
  • This holding plate 2 is provided for example in the form of an injection molded part made of a plastic.
  • an inlet opening 3 is provided, which is closed in the example shown by a closure element or a flap 4.
  • Closure element 4 and retaining plate 2 are integrally formed as an injection molded part, wherein the closure element 4 is connected via a film hinge 5, by which a pivot axis is formed with the holding plate 2.
  • a spring element 6 is provided in the form of a leaf spring to hold the closure element 4 in the first position shown, the closure position.
  • a longitudinal end 7 of the leaf spring 6 is connected by an embedding in the plastic fixed to the support plate 2.
  • the other longitudinal end 8 is movable on the closure element 4 on.
  • the leaf spring 6 is in the opening direction behind, in the plan view shown opposite to the opening direction, however, arranged in front of the closure element 4.
  • a hole 9 is further provided, in which the leaf spring 6 engages upon pivoting of the closure element 4 in the opening direction.
  • the leaf spring 6 is cambered, thus has transverse to the longitudinal axis on a continuous curvature. Due to this curvature, the leaf spring 6 touches the surface of the closure element 4 only at its longitudinal side edges.
  • the nonwoven material not shown in this figure for the sake of clarity, has around the inlet opening 3 a provided with self-adhesive film surface 20, which prevents the construction of a filter cake on this surface.
  • FIG. 2 is a schematic cross-sectional view through the retaining plate of FIG. 1 along the line AA, which runs along one of the longitudinal axes of the leaf spring 6.
  • the one longitudinal end 7 of the leaf spring 6 is embedded in the plastic of the holding plate 2 and thus fixed.
  • the other longitudinal end 8 touches in the region of the side edges of the leaf spring (the contact area) the closure element 4, so that is held at a suitably selected bias of the leaf spring, the closure element by the restoring force of the spring in the first position shown or closed position.
  • the holding plate 2 is connected to the nonwoven fabric 10 of a vacuum cleaner filter bag, for example glued.
  • the bag wall may also have fixedly connected fastening elements with which a retaining plate can then be detachably connected in a non-destructive manner, so that such a retaining plate can be reused several times.
  • the bag wall may have a filter structure, as for example in the EP 0 960 645 is described.
  • the nonwoven material 10 has around the inlet opening the self-adhesive film provided surface 20, which also in Fig. 1 is shown.
  • the hole 9 is in the example shown in blind hole, the bottom 12 is formed by an elastic film. Such elastic cover of the hole 9 can thereby take place that a TPE (thermoplastic polymer) is sprayed in 2K process on this area of the closure element. Due to such a floor, dirt is prevented from leaking out of the bag interior through the hole.
  • TPE thermoplastic polymer
  • the closure element 4 is acted upon by a suction air flow with a force which acts counter to the restoring force of the leaf spring 6. If the force of the suction air flow exceeds the restoring force of the leaf spring, the closure element in the opening direction 11, see FIG. 2 , and thus pivoted in the direction of the interior of the filter bag around the pivot axis formed by the film hinge 5.
  • the blind hole may also be formed by a depression in the closure element, so that the bottom is not elastic in the case of a stiff plastic.
  • the hole 9 may instead be a continuous hole. The latter is particularly advantageous in a design with a hole in the holding plate and not in the closure element, since then the connection of the holding plate with the filter material of the bag wall can be selected such that the hole does not open into the interior of the bag (ie flows outside the bag wall) and thus no dirt can escape from the bag through this.
  • FIG. 4 the photograph of a filter bag according to the invention is shown.
  • the immediate vicinity 20 of the inlet opening, which is closed by the closure element 4, is free of filter cake 21.
  • the surface 20 is realized by a film which substantially prevents the deposition of filtrate due to its smoothness and tightness.
