Definitions

  • Embodiments of the present invention relate to a device for cleaning or filtering an exhaust air stream by means of an air filter, as z. B. in household appliances, such as in particular, but not exclusively, vacuum cleaners.
  • Such exhaust air filter arrangements generally comprise an air or particle filter arranged in a filter housing. Frequently, two or three filter stages are arranged in series in a filter arrangement or assembly in order to increase the amount of dust collected or filtered out by the filter assembly to a maximum.
  • Known exhaust air filter types include, for example, a foam filter which is arranged directly in the exhaust air flow and which in itself already has a relatively high dust retention capacity.
  • An electrical and / or a HEPA (High Efficiency Particulate Airfilter) which is able to collect very small dust particles, in particular particles smaller than 1 ⁇ m, can then be arranged downstream of the foam filter, to retain or filter out the residual dust that escaped the upstream foam filter from the exhaust air flow.
  • known filter devices can also improve the odor of the exhaust air from a vacuum cleaner.
  • dust picked up when vacuuming even the smallest organisms, such as. 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 exhaust air filter accelerates and increases the growth and the multiplication of the mites and bacteria, as well as their Excrement formation, which can disadvantageously increase the moisture content in the filters with the additional formation of a warm, humid atmosphere. Due to the then accelerated decomposition processes, an unpleasant smell can develop, particularly in the dust filter bag, which can pollute the ambient air when vacuuming.
  • the US 5 289 612 A relates to a noise reduction system for an upright vacuum cleaner.
  • the EP 1 649 796 A2 so refers to a suction device.
  • the DE 29 17 094 A1 relates to a device for sound insulation in a vacuum cleaner.
  • the EP 1 551 269 B1 relates to noise reduction arrangement for a vacuum cleaner.
  • the US 2010/0 212 104 A1 Finally, relates to a filter chamber construction for a surface cleaning device that works on the cyclone principle.
  • the JP H05 - 317 208 A. and US 2007/0 113 528 A1 each disclose a filter device for cleaning an exhaust air flow by means of a filter arrangement, in particular in a household appliance, comprising: a housing for receiving the filter arrangement downstream of an exhaust air inlet of the housing, the housing having an exhaust air outlet for the exhaust air flow downstream of the filter arrangement which can be accommodated therein, the Exhaust air outlet is coupled via a plurality of air guide ribs to a relaxation area for the exhaust air flow arranged downstream of the exhaust air outlet, the air guide ribs being arranged parallel to one another in a transition area from the exhaust air outlet to the relaxation area, in order to rectify the air flowing to the relaxation area, and the relaxation area in front an outer outlet with outlet ribs of the vacuum cleaner outer housing is arranged.
  • One finding of exemplary embodiments of the present invention is to provide a filter arrangement with an air or particle filter, such as a HEPA filter, in a filter housing provided for this purpose, downstream of an engine-blower unit.
  • a vacuum cleaner to arrange, and a blown out of the filter arrangement in the downstream direction, filtered exhaust air downstream of the filter arrangement downstream air guide ribs before it is passed through a relaxation chamber downstream downstream of the relaxation space to the outside.
  • an exhaust air filter arrangement accommodated in a housing is therefore followed by air guide or air guide ribs and an exhaust air relaxation or expansion area for noise reduction.
  • exemplary embodiments provide a vacuum cleaner with a vacuum cleaner outer housing and a filter device for cleaning an exhaust air flow by means of a filter arrangement, comprising a housing for receiving the filter arrangement downstream of an exhaust air inlet of the housing.
  • the housing has an exhaust air outlet downstream of the filter arrangement which can be accommodated therein, wherein the exhaust air outlet is coupled via a plurality of air guide ribs to a relaxation area for the exhaust air flow arranged downstream of the exhaust air outlet.
  • a noise in the outlet area of the filter device can advantageously be reduced by the air guide ribs downstream of the filter arrangement in or on the housing and the relaxation space connected to the housing.
  • a filter arrangement with an air filter is arranged in the housing of the filter device and has a circumferentially arranged air guide rib on a downstream side of the air filter, which rib is designed to block the exhaust air flow from the air filter to an air-permeable sound absorber arranged downstream in series with the air filter. Ie, air filter, air guide rib and sound absorber together form the filter arrangement.
  • the filter arrangement can serve as an air-permeable sound absorber, for example, a sound-absorbing layer, which, for example, a sound-absorbing fleece or a sound-absorbing foam, such as. B. may have a melamine resin foam.
  • the sound absorber of the filter arrangement merely takes on a sound-absorbing function and / or rectifies the exhaust air flow.
  • particle and / or odor filtration by means of the sound-absorbing layer is not provided. This can already be done by the upstream air filter of the filter arrangement.
  • the relaxation area of the housing downstream of the air guide ribs is essentially funnel-shaped, such that it extends in a downstream direction from the exhaust air outlet, i.e. extended from a narrower beginning of the relaxation area to a wider end of the relaxation area.
  • the end of the relaxation area is directed to an outlet for the laminar, relaxed and / or calmed exhaust air from the household appliance in order to discharge the exhaust air to the environment. Due to an essentially funnel-shaped shape of the relaxation area, the exhaust air flow previously rectified by the air guide ribs can particularly advantageously continuously relax and calm down as it flows outward.
  • the air guide ribs are arranged essentially parallel to one another in a transition area from the exhaust air outlet in the housing to the relaxation area, in order to rectify the diffuse exhaust air flowing from the housing to the relaxation area by means of the air guide ribs, i.e. to obtain a flow that is as laminar as possible.
  • any orientation of the parallel air guiding ribs can be provided.
  • the housing, the air guide ribs and the relaxation area are preferably formed in one piece. That is, the housing, the air guide ribs and the relaxation area together form a one-piece or one-piece blow-out area for the exhaust air flow filtered by the filter arrangement.
  • the one-piece blow-out area comprising the housing, the air-guiding ribs and the relaxation area can thereby in particular by means of a plastic injection molding process. Due to the one-piece or one-piece design, on the one hand a complicated assembly of the blow-out area can be avoided, and on the other hand an increased noise development due to, for example, loose parts can be avoided.
  • the one-piece construction also means that there is no undesirable turbulent air turbulence caused by incorrectly connected individual parts or resulting gaps.
  • the air or particle filter is preferably airtight or leak-free coupled to the air-permeable sound absorber via the air-guiding or air-guiding rib in order to reduce noise. Diffuse blow-out air can thus be guided through the air filter rib without leakage and then calmly flow out of the outlet areas of the air-permeable sound absorber.
  • a filter arrangement constructed in this way can additionally reduce unpleasant and annoying noises in the blow-out area after an engine-blower unit.
  • Such a filter arrangement through its arrangement in the housing, can interact particularly synergistically with the filter device presented here to reduce a blow-out noise, since both the filter arrangement and the air guiding ribs located in or on the housing and the relaxation area can each provide for noise reduction.
  • Embodiments of the present invention also include a household appliance, such as an air conditioning system, but in particular a vacuum cleaner, with a filter device according to embodiments of the present invention.
  • a household appliance such as an air conditioning system, but in particular a vacuum cleaner, with a filter device according to embodiments of the present invention.
  • the Fig. 1 shows a schematic representation of a cross section through a filter device 10 for cleaning or filtering an exhaust air flow, which is indicated by reference numeral 11, by means of a filter arrangement 12.
  • the filter device 10 has a housing 13 for receiving, downstream of an exhaust air inlet 14 of the housing 13, of the filter arrangement 12, the housing 13 downstream of the filter arrangement 12 which can be accommodated therein having an exhaust air outlet 15 for the exhaust air flow 11, the exhaust air outlet 15 via a A plurality of air guide ribs 16 is coupled to a relaxation area 17 for the exhaust air flow 11 arranged downstream of the exhaust air outlet 15.
  • downstream means in the flow direction and “upstream” counter to the flow direction of the exhaust air flow 11.
  • a motor-blower unit can be arranged in the housing 13 in an area upstream, or in front of the housing region referred to as exhaust air inlet 14 Fig. 1 but is not shown.
  • This motor-blower unit can convey the still unfiltered exhaust air flow 11 through the area of the exhaust air inlet 14 to the filter arrangement 12, so that the exhaust air flow 11 can be air filtered by the latter.
  • the filter arrangement 12 can have an air filter 18, which can be, for example, a particle or suspended matter filter in the form of a HEPA filter.
  • HEPA filters can be used, for example, to filter out viruses, respirable dust, mite eggs and excretions, pollen, smoke particles, asbestos, bacteria, and many others toxic dusts, etc., from the exhaust air stream 11 are used.
  • some exemplary embodiments of the filter device 10 can be used, inter alia, in the medical field, for example in operating rooms, intensive care units and / or laboratories, and in clean rooms. The respective purpose is decisive for the selection of a filter class of the air filter 18.
  • Other embodiments of the filter device 10 can also be used for non-industrial applications, such as in household appliances, and in particular in vacuum cleaners.
  • Vacuum cleaners generally also include a motor-blower unit, by means of which a dust-containing exhaust air flow 11 can be filtered via the (downstream) filter arrangement 12 and then blown outwards.
  • the air filter 18 can be, for example, a HEPA filter, an electrical dust filter and / or a foam filter for odor absorption.
  • the air filter 18 can also be understood to mean a combination of different air, particle and / or odor filters.
  • the air filter 18 can be followed by an air-permeable sound absorber 19.
  • the sound absorber 19 can primarily serve to calm and / or rectify an exhaust air flow 11, which predominantly diffuses from the air filter 18, so that a blowout noise of the filter device 10 caused by the exhaust air flow 11 or related to it can be reduced.
  • the air-permeable sound absorber 19 can be a sound-absorbing or sound-reducing layer, according to exemplary embodiments.
  • this sound-absorbing or reducing layer 19 has no air purification function, but mainly serves to calm down and / or also to rectify the exhaust air flow 11 and thus to reduce noise.
  • the sound-absorbing material can be, for example, a sound-absorbing fleece or a sound-absorbing foam, such as a melamine resin foam.
  • An encircling air guide rib 20 arranged in the transition region between the air filter 18 and the sound absorber 19 is preferably designed to direct the exhaust air flow 11 from the air filter 18 to the air-permeable sound absorber or to the sound-absorbing layer 19 without leakage. That is, the sound absorbing layer 19 is the Air filter 18 by means of the air guiding rib 20 is quasi airtight or leakage-free for noise reduction, which is to be understood as meaning that no exhaust air should be able to flow between side walls 21 of the sound absorber 19 and the circumferential air guiding rib 20.
  • the circumferential air guide rib 20 forms a contour pocket in exemplary embodiments, the contour of which is designed to accommodate the air-permeable sound absorber 19 without play, so that no exhaust air can flow between the sound absorber 19 and the circumferential air guide rib 20.
  • the contour or the floor plan of the circumferential air guide rib 20 is thus adapted to a contour or a floor plan of the sound-absorbing layer 19.
  • the circumferential air-guiding rib 20 and the sound-absorbing layer 19 can have an essentially rectangular contour, corresponding to a cuboid volume of the sound absorber 19 and / or the air filter 18.
  • other layouts or contours, such as square or circular contours, are also conceivable with regard to the air filter 18, the circumferential air guide rib 20 and / or the sound-absorbing layer 19.
  • the inner dimensions of the circumferential air guide fin 20 can be, for example, slightly smaller than the outer dimensions of the sound absorber 19. In this way, after the sound absorber 19 has been introduced into the contour of the circumferential air guide fin 20, or the frame formed by this, take a kind of clamp fit in the circumferential air guide rib 20. In particular in connection with an elastic, sound-absorbing foam 19, freedom from play or leakage can thus be achieved.
  • the air-permeable sound absorber 19 can also be glued on its side surfaces 21 to inner surfaces of the circumferential air guide rib 20 in order to prevent exhaust air from flowing between the side walls of the sound absorber 19 and the air guide rib 20.
  • the circumferential air-guiding rib 20 has a lower height than the air-permeable sound absorber 19 to be accommodated therein, so that the side surfaces 21 of the air-permeable sound absorber 19 are only partially covered by the circumferential air-guiding rib 19 when the filter arrangement 12 is in the assembled state be like it is in the Fig. 1 is also recognizable. That is, the sound-absorbing, air-permeable layer 19 stands in the assembled state beyond a frame formed by the air guide rib 20 for the sound absorber 19, as a result of which the side surfaces 21 of the sound absorber 19 can be used as a blow-out surface in addition to a downstream exhaust air outlet surface of the sound absorber 19. This can advantageously contribute to a further reduction in a resistance formed by the sound absorber 19 and thus to a reduction in the air speed and the blowing noise.
  • the sound-absorbing or reducing layer 19 can, for example (in Fig. 1 seen in the downstream direction) have a height of approx. 20 mm.
  • the height of the circumferential air guide rib 16 is less than 20 mm.
  • the height of the circumferential air-guiding rib 19 is preferably less than half the height of the sound absorber 19 in order to provide sufficient lateral exhaust air discharge surface on the sound absorber 19.

With a height of the sound-absorbing foam 19 of approximately 20 mm, this results in a possible height of the HEPA filter 18 of approximately 25 mm.
  • the exhaust air flow 11 in the housing 13 can flow from the exhaust air flow exit surfaces of the filter arrangement 12 to the area of the exhaust air outlet 15. According to the filter arrangement 12, this will initially primarily be a turbulent flow.
