Definitions

  • Embodiments of the present invention relate to a concept for blowing an exhaust air flow in household appliances, such as in particular, but not exclusively, vacuum cleaners, can be used.
  • Such exhaust air filter assemblies generally include an air or particulate filter disposed within a filter housing. Often, two or three filter stages are arranged in series in a filter assembly to maximize a quantity of dust collected by the filter assembly.
  • Known exhaust filter types include, for example, a foam filter, which is arranged directly in the exhaust air flow and in itself has a relatively large dust retention capacity.
  • HEPA High Efficiency Particulate Air Filter
  • a vacuum cleaner which can measure a filling degree of the dust filter bag with dust by means of an arrangement that makes a pressure measurement in the dust area of an air stream before entering a dust bag.
  • the Arrangement is between an engine-fan unit and a downstream in the flow direction of the air filter device - here a dust filter bag - arranged.
  • the pent-up air is passed through openings in a perforated grid-shaped cylinder - which serves as an inlet to the filter bag - through a foam filter in a pressure chamber which is closed by an elastic membrane.
  • the foam filter serves to retain dust particles, which can lead to clogging and thus impairment of the measurement in the pressure chamber.
  • a realization of embodiments of the present invention is a Abluftausblas Scheme with a sound-absorbing or sound-absorbing medium, such as.
  • a sound-absorbing and air-permeable foam to provide.
  • the sound-absorbing foam which is also referred to below as foam filter
  • foam filter comparatively flat and still obtain a satisfactory Ausblasgehoffschdämpfung
  • This baffle arranged downstream of the foam filter can prevent exhaust air flowing in from the upstream direction from flowing directly through the foam and then exiting again unhindered on an opposite foam side.
  • the impact surface downstream of the foam filter forms a resistance to the exhaust air flow, thereby providing a diversion of the exhaust air within the sound absorbing foam toward lateral air exit surfaces of the foam filter.
  • the exhaust air does not flow through the sound-absorbing foam by the shortest route.
  • the exhaust air within the foam d. H. before its exit from the foam filter, deflected substantially transversely to its direction of flow to the side.
  • the flow path of the exhaust air is extended within the sound-absorbing foam, which in turn can contribute to a significant noise reduction in the discharge of a household appliance.
  • Embodiments of the present invention provide an arrangement for blowing an exhaust air stream, in particular from a household appliance, such.
  • a blow-out arrangement comprises an air-permeable and sound-absorbing foam or foam filter, on the upstream side of which the exhaust air flow can flow into the sound-absorbing foam substantially in one main flow direction.
  • an air-permeable and sound-absorbing foam or foam filter on the upstream side of which the exhaust air flow can flow into the sound-absorbing foam substantially in one main flow direction.
  • there is one arranged at least partially covering air-impermeable baffle which is designed to divert the exhaust air flow before its exit in the sound-absorbing foam from its main flow direction.
  • the air-permeable and sound-absorbing foam of the foam filter may be, for example, a polyurethane foam (PU foam) or a melamine foam.
  • the baffle is configured to place the exhaust air flow within the sound absorbing foam upstream of the baffle in a transverse flow having a directional component that is substantially parallel to the baffle. This can thus result in a correspondingly shaped and arranged impact surface to a cross flow, which is substantially perpendicular to the main flow direction of the exhaust air.
  • a direct (i.e., shortest path) flow through the foam filter and instead divert the exhaust air flow within the foam filter substantially transverse to the main or inflow direction.
  • the exhaust air no longer flows on direct, d. H. shortest way through the foam filter, but must cover a longer way to its exit from a side area of the foam. Due to this longer flow path, the exhaust air flow in the foam filter can be calmed more than usual, and thus a Ausblasgehoffsch the home appliance can be significantly reduced.
  • the baffle has an air-impermeable center portion and air-permeable side portions disposed laterally with respect to the mid-portion to substantially recirculate a laterally displaced air exit from the foam substantially through the air-permeable side portions of the baffle for exhaust air flowing transversely to the mid-portion in the foam Main flow direction to allow.
  • the air-permeable side sections are laterally offset on one of the inflowing exhaust air opposite side of the foam filter.
  • the impact surface completely covers the sound-absorbing foam, for example, so that exhaust air outlet regions are located on a circumference of the foam filter lateral air outlet surfaces, which may be substantially perpendicular to the exhaust air inlet surface.
  • an air filter eg HEPA filter
  • the holding frame between the air filter and the air-permeable and sound-absorbing foam has a grid on which the foam can be supported. It is therefore a cascade of air filter, downstream arranged foam filter and turn downstream arranged thereon impact baffle or baffle. The foam filter can then be so pressed pressed between grid and baffle.
  • the baffle surface is preferably arranged downstream of the air-permeable and sound-absorbing foam, so that the baffle surface and the foam are in direct contact with each other.
  • the baffle can thus rest directly on the downstream side of the sound-absorbing foam.
  • the baffle may, for example, be glued to the foam to additionally fix the foam.
  • the baffle may, according to some embodiments, also be an air-impermeable layer applied to one side of the foam, such as e.g. B. a paint or the like.
  • the decisive factor is that it ensures that an exhaust air flow flowing in on one side of the foam opposite the impact surface can not flow through the foam on the shortest path but is deflected essentially parallel to the impact surface in order to increase the flow path of the exhaust air flow through the foam extend and thus to calm the exhaust air before it exits the foam.
  • the baffle may, together with its air-permeable side portions, form part of an outer housing of the household appliance form.
  • the baffle or impact baffle for example, have an injection-molded plastic part, which can form a visible part of the outer housing.
  • the baffle surface may additionally comprise latching elements. These may be in the form of hooks and / or eyelets, for example.
  • FIG. 1 For exemplary embodiments of the present invention likewise include a method for blowing off an exhaust air stream, in particular from a domestic appliance, with a step of arranging an air-permeable and sound-absorbing foam filter, on the upstream side of which the exhaust air flow can flow into the air-permeable and sound-absorbing foam filter essentially in one main flow direction, arranging, on a downstream side of the air-permeable and sound-absorbing foam filter, an air-impermeable baffle surface at least partially covering the foam filter so that the exhaust air flow can be deflected from its main flow direction due to the baffle in the sound-absorbing foam filter, and a step of arranging upstream to the foam filter an air filter located in a support frame, the support frame having a grid between the air filter and the foam filter, on which the foam filter can support.
  • FIGS. 1a to 1c show various embodiments of arrangements 10a, 10b and 10c for blowing an exhaust air stream 11. Such arrangements are in household appliances, such. As vacuum cleaners are used to blow out filtered or unfiltered exhaust air.

  • the main flow direction may be substantially perpendicular (ie, for example, in an angular range of 70 ° to 110 °) to a surface of the upstream side 13.
  • all of the illustrated arrangements 10a, 10b, and 10c each have one on a downstream side 14 (ie, those shown in FIGS FIGS.
  • the baffle 15 is formed or arranged so as to deflect the exhaust air flow 11 within the foam filter 12 from the main flow direction and, for example, to place it in a transverse flow having a directional component 16 substantially is parallel to the baffle 15, ie with this example includes an angle in an angular range of -20 ° to 20 °.
  • the air-permeable and sound-absorbing foam of the foam filter 12 may be a polyurethane foam (PU foam) or a melamine foam, each of which has particularly good sound-absorbing properties.
  • PU foam polyurethane foam
  • melamine foam a polyurethane foam
  • the exhaust air flow 11 can be calmed as it flows through such a sound-absorbing foam, so that air leakage noise can be reduced by providing such a sound-absorbing foam.
  • the highest possible sound attenuation is, however, achieved by a corresponding thickness or thickness of the foam in the main flow direction.
  • embodiments now permit the use of sound-absorbing foams 12, which have a relatively low thickness or height h in comparison with the prior art (see, for example, FIG. Fig. 1a ) respectively.
  • This is accomplished by the air-impervious baffle 15 disposed downstream of the foam 12, which is configured in accordance with embodiments to move the exhaust air stream 11 in the foam 12 in a direction toward the side (left and right in FIGS Fig. 1a-c ) to the impact surface 15 located air outlet surfaces 17 of the foam 12 off or redirect.

  • the baffle 15 can be formed in this way be after a deflection or deflection of the exhaust air flow 11 in the foam 12 to allow a relation to an inflow offset outflow of the exhaust air 11 from the downstream side 14 of the foam filter 12.
  • the baffle 15 may be formed, for example less wide than the upstream thereto located foam 12 (see Fig. 1a ).
  • the baffle 15 may also include recesses or grid assemblies laterally of the airtight central portion forming the air-permeable side portions 18 (see FIG Fig. 1b ).

  • the baffle 15 is disposed downstream immediately after the air-permeable and sound-absorbing foam 12, so that the baffle 15 and the foam 12 are in contact with each other.
  • the baffle 15 may be in direct contact with the downstream side 14 of the foam 12. In this way, the deflection of the exhaust air flow 11 within the foam 12 can be made particularly efficient.
