  • the air enters the flat filter 3 on the underside and flows through the flat filter 3 in the axial direction 10 from bottom to top, with the cleaned air exiting at the top of the flat filter 3.
  • the air flow Since the coarse dirt carried by the air flow is already separated at the bottom of the dust collection container 12 before it flows through the flat filter 3, the air flow only carries with it a certain residual amount of dust and dirt. These dust and dirt particles are filtered away by the flat filter 3.
  • the flat filter 3 is flowed through evenly and over a large area in the direction from bottom to top. This has the advantage that a large amount of air can be filtered at low speed, so that the pressure drop across the flat filter 3 is small. Due to the slow, large-area flow through the filter material, the noise development in the filter arrangement 1 is kept low. Because of the previous separation of coarse dirt, not too much dust accumulates on the underside of the flat filter 3 over time, so that the underside of the flat filter 3 only needs to be cleaned comparatively rarely.
  • the cleaned air exits at the top of the flat filter 3 and passes through the top of the flat filter 3 located air outlet area to the air outlet channel 6.
  • the cleaned air flow is guided to the air outlet opening 13 by means of the curved guide surface 15 and exits there in the direction of arrow 14.

  • a space-saving design of the filter arrangement 1 is achieved, particularly in the axial direction 10.
  • the advantage of this is that for a given height of the filter arrangement 1, correspondingly more space can be made available for the dust collection container 12 due to the small space requirement for the filter frame 2.
  • the available height for the filter arrangement 1 is limited due to the underride behavior. Since the air supply, the air exhaust and the flat filter 3 can all be accommodated within the relatively narrow axial area, the available installation space can be used as much as possible for the dust collection container 12, so that it can absorb a comparatively large amount of dust and dirt before emptying becomes necessary.
  • the compact design of the filter arrangement 1 is achieved by multiple deflection of the air flows. The air entering the filter arrangement 1 has a dominant component perpendicular to the axial direction 10, is then directed to the bottom of the dust collection container 12, is deflected there and then flows through the flat filter 3 in the axial direction 10. The cleaned air is redirected through the cover 18 and guided through the air outlet channel 6, with the emerging air emerging laterally and thus having a dominant flow component perpendicular to the axial direction 10.
  • both the air is supplied and removed from the side at the level of the flat filter 3.
  • only one of the air inlet opening 8 and the air outlet opening 13 could be provided at the level of the flat filter 3, whereas the other Air opening could be arranged, for example, at the lower end or at the upper end of the filter arrangement 1.
  • both the air inlet opening 8 and the air outlet opening 13 as well as the flat filter 3 itself are arranged within a narrowly limited axial area of the filter arrangement 1, because in this case a particularly compact design results.
  • a further advantage of the filter arrangement 1 is that the air inlet opening 8 and the air outlet opening 13 are arranged on one side of the filter frame 2 in a common plane. This arrangement facilitates the fluidic contacting of the air inlet channel 5 and the air outlet channel 6 from the vacuum cleaner.
  • a larger common sealing element can be used instead of two individual sealing elements.
  • the filter arrangement 1 shown is that the inflow direction and outflow direction designated by arrows 9 and 14 are oriented opposite and equal to one another. Both the inflow direction and the outflow direction are oriented perpendicular to the axial direction 10 of the filter arrangement 1.
  • the inflowing air flow and/or the outflowing air flow could each be oriented obliquely to the axial direction 10, with the dominant component of the inflow direction and the outflow direction also being oriented perpendicular to the axial direction 10 in these cases, in addition due to the oblique coupling comparatively smaller component in the axial direction 10 is added.
  • FIG 3 a front view of the filter frame 2 is shown. You can see the air inlet opening 8 for the air inlet channel 5 and the air outlet opening 13 for the air outlet channel 6, which are arranged at the same height when viewed in the axial direction 10.
  • the contour of the guide surface 11 is within the air inlet opening 8 of the air inlet channel 5, which directs the incoming air downwards to the dust collection container 12.

  • the flat filter 3 can be on the underside, i.e. on the inside Figure 4 shown air inlet surface of the flat filter 3, be equipped with a removable protective filter.
  • This protective filter upstream of the flat filter 3 acts as a coarse dirt filter and prevents, for example, dust mice and lint from reaching the flat filter 3.
  • This upstream protective filter makes cleaning the flat filter 3 easier because coarse dirt does not stick to the filter material of the flat filter 3.
  • FIG 5 the filter frame 2 with the flat filter 3 is shown in a top view, with the filter folds of the flat filter 3 extending radially outwards from the central region 4 being visible.
  • the sector-shaped area 7 for the air inlet channel 5 can again be seen, to which the filter folds of the flat filter 3 adjoin on both sides.
  • the entire flat filter 3 within the filter frame 2 is shifted to the left by a certain lateral offset 22 relative to the center of the filter frame 2 in order to create space for the air outlet duct 6 on the right side.
  • the central area 4 of the flat filter 3 is therefore not located in the middle of the filter frame 2, but is arranged laterally offset from the middle of the filter frame 2.
  • This eccentric arrangement of the flat filter 3 creates space for the air outlet channel 6, which removes the air cleaned after flowing through the flat filter 3 and outputs it through the air outlet opening 13 in the direction of the arrow 14.
  • the sector-shaped region 7 preferably extends over an angular range of more than 10°, more preferably over an angular range of more than 20° and more preferably over an angular range of more than 30°.
  • the sector-shaped region 7 preferably extends over an angular range of less than 60°, more preferably over less than 50°, more preferably less than 40°.
  • FIG 6 shows a cross section through a cleaning robot 23, in which a filter arrangement 1 in the Figures 1 to 5 shown type is used.
  • the filter arrangement 1 is particularly suitable for use in a cleaning robot 23 because, despite its low design, it provides a dust collection container 12 with a sufficiently large volume.
  • the cleaning robot 23 has a receptacle 24 for the filter arrangement 1, into which the filter arrangement 1 is inserted from above and then locked, for example by pivoting the handle 19.
  • the cleaning robot 23 is equipped with a seal for the air inlet opening 8 and the air outlet opening 13 of the filter arrangement 1.
  • a connection is established between the air supply channel 25 of the cleaning robot 23 and the air inlet channel 5 of the filter arrangement 1 via the air inlet opening 8.
  • the incoming air is directed according to the arrow 26 through the guide surface 11 to the bottom of the dust collection container 12, whereby coarse dirt is separated.
  • the air flow is deflected at the bottom of the dust collection container 12 and then flows through the flat filter 3 in the axial direction 10 from bottom to top.
  • the cleaned air is fed via the air outlet duct 6 and the air outlet opening 13 of the filter arrangement 1 to an air discharge duct of the cleaning robot 23, which, however, is in Figure 6 is not shown.
  • the cleaned air is then released to the outside via this air discharge duct.
