Definitions

  • the invention relates to a fan, in particular ceiling fan with a housing, air enters at the bottom and / or top and air exits from the other sides.
  • the object of the invention is to improve a fan of the type mentioned in such a way that, with a simple construction, the underside of the housing is not visible and the outside of the housing is protected against damage.
  • Such a flat, in particular curved cover covers the underside of the fan, in particular its suction opening, so that the underside of the housing has to be designed with little effort.
  • the underside of the housing remains invisible, so that after a while any dirt on the intake opening does not become visible.
  • the protruding outer edges of the cover can absorb impacts, so that the lamellae of the air outlets are protected.
  • the cover when the cover is convexly curved on the outside is particularly advantageous.
  • the cover can be attached at a distance from the underside of the housing so that there is a flat space between the housing and the cover.
  • cover forms a cone or cylinder section.
  • the cover should also have numerous air passage openings.
  • the cover be formed by a disk or plate made of metal, plastic or glass. It is also an advantage if the corners of the cover are rounded.
  • a filter is attached in front of the suction opening between the cover and the underside of the housing.
  • the cover should also be arranged horizontally.
  • the fan in particular as a ceiling fan, has a fan interior 1 in which a fan wheel 3 driven by an electric motor 2 is fastened.
  • a fan wheel 3 driven by an electric motor 2 is fastened.
  • the fan wheel sucks the air into the fan interior 1 via a lower suction opening 4, the fan wheel 3 and electric motor 2 being surrounded all around by a curved heat exchanger 5 which has numerous tubes 6 which are connected to one another and lead to connecting pieces 7, 8 .
  • the suction opening 4 can also be arranged on the upper side 4 of the fan housing if the fan is fastened on the underside to an intermediate ceiling and / or to an air duct.
  • the suction opening 4 is covered by an exchangeable filter 9. Furthermore, a lower flat cover in a curved shape is attached to the underside of the fan housing, which projects beyond the fan housing on all sides.
  • the fan housing has an air outlet 11 on all four sides and corner areas 12 located between them. These corner areas 12 are curved as partial cylinders in a quarter-circle shape and each end at an air outlet 11.
  • each air outlet 11 there are horizontal pairs of lamellae 13 which guide the escaping air.
  • the two fins of a pair of fins 13 form an intermediate space 14 between them which is open on both end faces in order to be able to suck in air laterally there.
  • the open end faces 15 of the pairs of fins 13 are covered by a side wall 16 which has air passage openings 17 in the form of horizontal elongated holes.
  • the side wall openings can also be very small and in particular sieve-shaped.
  • the side wall 16 is missing and the air flows unhindered from a lateral space 20 to the lamella intermediate spaces 14.
  • the corner area 12 forms in its interior an air supply space (corner space) 20 which fills the area between two air outlets 11 and is delimited by the air-permeable side wall 16 towards the two air outlets 11 or towards the pairs of slats. Furthermore, the air supply space (corner space) 20 is limited on the outside by an outer curved cover wall 21, which serves as a corner cover.
  • the cover wall 21 has numerous air passage openings, and can also be sieve-shaped.
  • the cover wall 21 is formed in one piece with the two side walls 16, so that the cover wall ends on both sides in the side walls 16 which are bent inwards at right angles with respect to the wall 21.
  • the air supply space 20 is delimited by an air-impermeable inner wall 22 which is arranged obliquely in such a way that it forms an angle of 45 degrees with the plane of the air outlets 11.
  • the walls 16, 21 and 22 are vertical.
  • the room 20 can receive air through its top and / or bottom if these are designed to be open.
  • the side wall 16 ends in front of the upper cover plate 23, so that air can flow into the space 20 from above.
  • the underside of the room 20 can be closed by a perforated floor 24, so that air can also flow into the room 20 from the underside of the device.
  • the cover can be square or rectangular, the corners preferably being rounded.
  • the cover 10 has a convex curvature when viewed from below.
  • the cover 10 is attached at a distance from the underside of the housing, so that there is a space between the cover 10 and the underside of the housing through which the sucked air can distribute and the filter 9 is also arranged.
  • the cover 10 has numerous air passage openings at regular intervals, so that air can be drawn in through the cover.
  • the cover is formed by a disc or plate made of metal, plastic or glass.
