Definitions

  • the invention relates to a filter according to the preamble of the first claim.
  • the filter bag and stiffening plate can consist of compostable materials
  • the necessary seals such as ring seals in an inlet opening or other sealing elements, consist of non-decomposable rubber-elastic materials.
  • the invention has for its object to take measures in a filter for vacuum cleaners by which compostability is ensured.
  • the entire filter can be made of a compostable, biodegradable when using only one material
  • biodegradable polymer materials can be limited to a single filter part, in particular an elastic sealing element, while one or more further filter parts made from biological degradable fleece, tissue, paper, natural fiber, cardboard and the like. Material can be manufactured and put together. If an inlet opening is provided in a stiffening plate which is assigned to a flexible filter bag and is intended to work closely with an air inlet socket, then the inlet opening is expediently assigned an annular seal made of the biodegradable polymer material and in particular made of an elastic film. The stiffening plate and the ring seal can also be made in one piece.
  • the filter can also be designed as a multi-layer filter surface, which is composed of layers of nonwoven, fabric, grid or the like. These layers can be connected to one another in the region of inner or outer edges and in particular welded to one another.
  • a filter disk that fills the free cross section in a cassette frame made of hard, foamed polymer material that is open on both sides, for example, all parts being made of biodegradable material. Since biodegradable polymer materials only retain their initial properties in the free environment for a limited period of time, it is advisable to enclose one or more of the filters in a common packaging in an airtight manner in order to delay the biodegradation. It is advisable to provide an expiry date on the packaging and / or on the filter.
  • the polymer material can be based on starch, such as is obtained from potatoes, corn or the like.
  • FIG. 2 shows the filter according to FIG. 1 in plan view of the stiffening plate
  • FIG. 3 is a plan view of a filter slotted in the filter surface
  • FIG. 4 is a partial section of the filter of FIG. 3 in side view
  • FIG. 5 is a plan view of a foamed filter disc
  • FIG. 6 is a partially sectioned illustration of the filter of FIG. 5 in side view
  • FIG. 8 is a partial view according to FIG. 7 with an additional sealing element
  • FIG. 9 is a plan view of the arrangement of FIG .. 7
  • a filter bag 1 made of air-permeable material is provided at one end with a stiffening plate 2, in which there is an inlet opening 3 for connection to a dust air inlet nozzle, which is arranged in a vacuum cleaner.
  • a sealing element 4 which in the present case is designed as an annular seal made of a film and surrounds the inlet opening 3.
  • the inner diameter of the ring seal 4 is smaller than that of the inlet opening 3.
  • the sealing element 4 is located on the side of the stiffening plate 2 facing the interior of the dust bag 1.
  • the filter parts 1 to 4 can consist entirely of a biodegradable polymer material. Then at least the stiffening plate 2 can be manufactured in one piece with the sealing element 4.
  • the filter bag 1 from filter paper or rotten fleece, fabric and the like. From natural fibers, while the stiffening plate can also be made from rotten cardboard. Then the use of a biodegradable material is limited to the design of the sealing element 4. Overall, however, the filter formed in this way remains compostable, so that its disposal via the organic waste can be carried out without problems.
  • the filter can also be designed as a disc filter according to FIGS. 3 and 4, as it is used in vacuum cleaners before and / or after an engine fan.
  • the filter is made up of several layers 5, 6, 7, the middle layer 6 being made of compostable natural fiber products such as paper, cardboard, wadding, mat, granules, fleece, fabric or grids with filter properties, while the outer layers 5 and 7 are made of biodegradable, air-permeable polymer material. These outer layers can protrude beyond the middle layer on the outer edge and be welded or glued to one another in order to achieve a stable structure and an undetachable assignment of layers 5-7. If the middle layer is also made of the polymer material, then all three layers can be welded or glued together at their edges 8.
  • the porosity of the layers 5-7 is preferably selected differently. If an opening or a continuous slot 9 is required in the surface of the disc filter in order to be able to slide the filter disc onto an adapted holding element assigned to the relevant vacuum cleaner, these are also in this area the layers concerned are expediently connected to one another.
  • the filter disk can also be produced as a single-layer disk made of open-pore foamed biodegradable polymer material, with one or more slots 9 being able to be provided within the filter surface even during foaming or in a later cutting process.
  • FIGS. 7 to 9 can also be inserted into a cassette frame 11 according to FIGS. 7 to 9, which in turn is to be inserted into a corresponding holder within a vacuum cleaner.
  • an elastic sealing element 4 in the form of an O-ring in a radially angled edge 12 in FIG. 8.
  • the cassette frame 11 and the sealing element 4 are again made of biodegradable polymer material, the cassette frame 11 being made of hard, possibly foamed polymer, while the sealing ring 4 can be elastically foamed or made as a sealing lip.
  • the filter disk 10 is constructed in one or more layers and is not intrinsically rigid, then a grid made of hard, biodegradable polymer material can expediently be arranged in front of and behind the filter disk 10 in the flow direction of the air to be passed and filtered. At least one of the gratings 13 can be detachably held in the cassette frame 11 in order to be able to replace the filter disk 10 if necessary after removing this grating 13. In addition to the materials already listed, it is also possible to present the filter disk 10 as a package made of activated carbon. The compostability of such a filter is guaranteed in accordance with the objectives of environmental protection.
