Definitions

  • Embodiments of the present invention relate to a concept for blowing out an exhaust air stream in household appliances, such as vacuum cleaners, in particular, but not exclusively, can be used.
  • Such exhaust air filter assemblies generally include an air or particle filter arranged in a filter housing. Often two or three filter stages are arranged in series in a filter arrangement or assembly in order to maximize an amount of dust caught or filtered out by the filter assembly.
  • Known exhaust air filter types include, for example, a foam filter that is placed directly in the exhaust air flow and already has a relatively high dust retention capacity.
  • An electrical and/or HEPA (High Efficiency Particulate Airfilter) filter capable of capturing very small dust particles, particularly particles smaller than 1 ⁇ m, can then be placed downstream of the foam filter, to retain or filter out the residual dust from the exhaust air flow that escaped the upstream foam filter.
  • known filter devices can also improve the smell of the exhaust air from a vacuum cleaner.
  • dust picked up when vacuuming for example, even the smallest organisms, such as e.g. B. bacteria or dust mites get into the dust filter of a vacuum cleaner, especially in the dust filter bag.
  • a massive accumulation of all impurities in the dust filter bag and possibly also in the after-air or exhaust air filter accelerates and intensifies the growth and multiplication of mites and bacteria, as well as their formation of excrement, which can adversely increase the moisture content in the filters with the additional formation of a warm, humid atmosphere.
  • an unpleasant odor can develop, especially in the dust filter bag, which can pollute the ambient air when vacuuming.
  • sucked-in air after passing through the dirt pickup and the dust and/or odor filter, is generally fed via a blow-out duct to a plurality of housing slots arranged adjacent to one another, as is the case, for example, in the documents JP 03272721A , DE 198 43 719 A1 and U.S. 7,434,293 B2 is shown.
  • Considerable flow velocities can be reached when the exhaust air emerges from the housing slots, which in turn can produce unpleasant blow-out noises.
  • efforts are made to make the exhaust channel and an exit point in the area of the housing of the household appliance as large as possible in order to obtain low exhaust resistance, as is the case, for example, in DE 33 11 494 A1 will be shown.
  • a vacuum cleaner which can measure the degree to which the dust filter bag is filled with dust using an arrangement which carries out a pressure measurement in the accumulation area of an air flow before it enters a dust bag.
  • the arrangement is arranged between a motor/fan unit and a filter device—here a dust filter bag—connected downstream in the flow direction of the air.
  • the pent-up air is guided through openings in a perforated lattice-shaped cylinder - which serves as the inlet to the filter bag - through a foam filter into a pressure chamber which is closed off by an elastic membrane.
  • the foam filter serves to hold back dust particles that can lead to blockages and thus impairment of the measurement in the pressure chamber.
  • Part of a main air flow is guided into the pressure chamber via a partially airtight baffle. When the dynamic pressure in the stagnation area of the air flow decreases, air that has accumulated in the pressure chamber is routed back to the cylinder into the main air flow.
  • One finding of embodiments of the present invention is an exhaust air blowout area with a noise-insulating or sound-absorbing medium, such as B. to provide a sound-absorbing and air-permeable foam.
  • a noise-insulating or sound-absorbing medium such as B. to provide a sound-absorbing and air-permeable foam.
  • a so-called impact screen or impact surface is installed downstream (ie viewed in the direction of an exhaust air flow) from the sound-absorbing foam intended.
  • This impact surface which is 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 side of the foam.
  • the baffle surface arranged downstream of the foam filter forms a resistance for the flow of exhaust air and thereby ensures that the exhaust air is deflected within the sound-absorbing foam to the lateral air outlet surfaces of the foam filter.
  • the exhaust air cannot flow through the sound-absorbing foam over the shortest path by means of the baffle surface arranged on the downstream side of the foam filter.
  • the exhaust air is deflected to the side within the foam, ie before it emerges from the foam filter, essentially transversely to its inflow direction. This lengthens the flow path of the exhaust air within the sound-absorbing foam, which in turn can contribute to a significant noise reduction in the outlet area of a household appliance.
  • Embodiments of the present invention provide an arrangement for blowing out an exhaust air flow, in particular from a household appliance such. B. a vacuum cleaner ready.
  • a blow-out arrangement comprises an air-permeable and sound-absorbing foam or foam filter, on the upstream side of which the exhaust air stream can flow essentially with a main flow direction into the sound-absorbing foam.
  • an air-impermeable impact surface that at least partially covers it and is designed to deflect the exhaust air flow from its main flow direction before it exits in the sound-absorbing foam.
  • the air-permeable and sound-absorbing foam of the foam filter can be, for example, a polyurethane foam (PU foam) or a melamine foam.
  • PU foam polyurethane foam
  • melamine foam a polyurethane foam
  • the baffle is configured to impart a transverse flow to the exhaust airflow within the sound absorbing foam upstream of the baffle, having a directional component that is substantially parallel to the baffle. With an appropriately shaped and arranged impact surface, this can therefore lead to a transverse flow that is essentially perpendicular to the main flow direction of the exhaust air. With embodiments of the present invention, it is therefore possible to prevent a direct flow through the foam filter (i.e. using the shortest route) and instead to deflect the exhaust air flow within the foam filter essentially transversely to the main or inflow direction. As a result, the exhaust air no longer flows on a direct, i. H.
  • the impact screen or baffle has an air-impermeable middle section and air-permeable side sections arranged laterally to the middle section, in order, by means of the air-permeable side sections of the baffle, for exhaust air flowing transversely upstream to the middle section in the foam to have a laterally offset air outlet from the foam essentially again in the main flow direction to allow.
  • the air-permeable side sections are laterally offset on a side of the foam filter that is opposite to the inflowing exhaust air.
  • An air filter (e.g. HEPA filter) is arranged in a holding frame upstream of the air-permeable, sound-absorbing foam, the holding frame having a grid between the air filter and the air-permeable and sound-absorbing foam, on which the foam can be supported. It is therefore a cascade of an air filter, a foam filter arranged downstream of it, and an impact screen or impact surface arranged downstream of it. The foam filter can then be arranged so that it is pressed between the grid and the impact surface.
  • HEPA filter e.g. HEPA filter
  • the baffle is preferably arranged downstream immediately after the air-permeable and sound-absorbing foam, so that the baffle and the foam are in direct contact with one another.
  • the baffle can thus directly on the downstream side of the sound absorbing foam.
  • the impact surface can be glued to the foam, for example, in order to additionally fix the foam.
  • the baffle can also be an air-impermeable layer applied to one side of the foam, e.g. B. a paint finish or the like.
  • the decisive factor is that it ensures that a flow of exhaust air flowing on a side of the foam opposite the impact surface cannot flow through the foam via the shortest path, but is deflected in it essentially parallel to the impact surface in order to close the flow path of the exhaust air flow through the foam extend and thus calm the exhaust air before it exits the foam.
  • the impact surface can form part of an outer housing of the household appliance together with its air-permeable side sections.
  • the impact surface or impact screen can have, for example, an injection molded plastic part, which can form a visible part of the outer housing.
  • the impact surface can additionally have latching elements according to exemplary embodiments. These can be in the form of hooks and/or eyes, for example.
  • FIG. 1 For exemplary embodiments of the present invention, also include a method for blowing out an exhaust air flow, in particular from a household 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 with a main flow direction, arranging, on a downstream side of the air-permeable and sound-absorbing foam filter, an air-impermeable baffle 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 of the foam filter , An air filter located in a holding frame, the holding frame having a grid between the air filter and the foam filter on which can support the foam filter.
  • FIGS. 1a to 1c 10 show various exemplary embodiments of arrangements 10a, 10b and 10c for blowing out an exhaust air stream 11.
  • Such arrangements are used in household appliances such as e.g. B. vacuum cleaners, for blowing out filtered or unfiltered exhaust air.
  • Arrangements 10a, 10b and 10c shown each have an air-permeable and sound-absorbing foam filter 12, on whose upstream side 13 (ie, those shown in Figs Figures 1a to 1c bottom side) the exhaust air flow 11 can flow into the foam filter 12 essentially with a main flow direction.
  • the main flow direction can run essentially perpendicular (ie, for example, in an angular range of 70° to 110°) to a surface of the upstream side 13 .
  • all of the assemblies 10a, 10b and 10c shown each have one on a downstream side 14 (ie, those shown in Figs Figures 1a to 1c upper side) of the foam filter 12 and this at least partially covering air-impermeable baffle 15 on.
  • the baffle 15 is designed or arranged in such a way to deflect the exhaust air flow 11 within the foam filter 12 from the main flow direction and, for example, to convert it into a cross flow that has a directional component 16 that is essentially is parallel to the impact surface 15, ie, encloses an angle in an angular range of -20° to 20° with this, for example.
  • the air-permeable and sound-absorbing foam of the foam filter 12 can 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 down when flowing through such a sound-absorbing foam, so that air outlet noises can be reduced by the provision of such a sound-absorbing foam.
  • the highest possible soundproofing is achieved by a corresponding thickness or strength of the foam in the main flow direction.
  • exemplary embodiments allow the use of sound-absorbing foams 12, which have a relatively small thickness or height h compared to the prior art (see e.g. Fig. 1a ) exhibit.
  • This is achieved by the air-impermeable baffle 15 arranged downstream of the foam 12, which is designed according to exemplary embodiments to direct the exhaust air flow 11 in the foam 12 in a direction towards the side (left and right in the Fig. 1a-c ) to the impact surface 15 located air outlet surfaces 17 of the foam 12 off or deflect.
  • the lateral air outlet surfaces 17 can either be on the downstream side 14 of the foam filter 12 (see Fig. 1a, b ).
  • the lateral air outlet surfaces 17 can lie on lateral peripheral surfaces of the foam 12 which are not covered by the impact surface 15.
  • the baffle surface 15 can have an air-impermeable middle section and air-permeable side sections 18 arranged laterally to the middle section, in order, by means of the air-permeable side sections 18 of the baffle surface 15, for exhaust air 11 flowing transversely upstream to the middle section 15 in the foam 12 to allow air to escape from the foam 12 the downstream side 14 of the foam 12.
  • the baffle surface 15 can be designed in such a way that, after the exhaust air flow 11 has been deflected or deflected in the foam 12 , the exhaust air 11 can flow out of the downstream side 14 of the foam filter 12 , offset relative to an inflow area.
  • the impact surface 15 can, for example, be made less wide than the foam 12 located upstream of it (see FIG Fig. 1a ).
  • the impact surface 15 can also have recesses or lattice arrangements located laterally to the air-impermeable central section, which form the air-permeable side sections 18 (see FIG Fig. 1b ).
  • Embodiments are also conceivable in which the impact surface 15 completely covers the foam filter 12 located upstream of it or its downstream side 14, ie also over its entire width.
  • the exhaust air flow 11 is deflected within the foam 12 until it can exit again at the lateral foam or air outlet surfaces 17 that are not covered by the impact surface 15 (see 1c , left- and right-hand foam surfaces).
  • the impact surface 15 is preferably arranged downstream immediately after the air-permeable and sound-absorbing foam 12, so that the impact surface 15 and the foam 12 are in contact with one another.
  • 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 configured particularly efficiently.
  • the baffle surface can be, for example, a plastic plate, a metal or sheet metal plate, or an air-impermeable layer that rests directly on the downstream side 14 of the foam filter 12 .
  • the direct contact between the foam 12 and the impact surface 15 can be produced in various ways. For example, it can be a pressure contact, which comes about by pressing the foam 12 against the impact surface 15 .
  • the foam 12 and the impact surface 15 can also be glued together, for example, in order to obtain an additional fixation of the foam 12 and the impact surface 15 relative to one another.
