  • the device may be centrally split to define interchangeable halves and an iris diaphragm is provided, normally removed from the air passages, but adapted to close the air passages.
  • This invention relates to a ventilating device mountable on a wall, window or the like of a room to be ventilated, for replacing vitiated air by fresh air, which comprises a split annular chamber defined by wall means which are formed with a constriction and bent oif portions forming central sleeve means immediately adjacent the constriction and extending in a plane perpendicular to the plane of the annular chamber, an electric motor fixed to the sleeve means and coaxial therewith, a coaxially arranged impeller system drivably mounted on the electric motor and having inner and outer blade means set to opposite angles of attack for opposite thrust performance, the inner blade means carrying fixed to their tips a concentric open hollow cylinder carrying fixed to its circumference the outer blade means arranged for rotation within the annular chamber concentrically surrounding the impeller system, the open hollow cylinder affording together with the sleeve means a central passage for an air stream produced by the inner blade means, while at the same time dividing the annular chamber from the central passage, an annular
  • peripheral air inlet openings as arpositioned outside the room to be ventilated are disposed only below the impeller system and such of the peripheral air outlet openings as are positioned within the room to be ventilated are disposed only above the impeller system. In this manner it is prevented, on the one hand, that rain can enter from outside and, on the other hand, that draft can occur in the room to be ventilated.
  • both the annular chamber and the annular partition are split along their transverse central plane, thereby to form two identical and interchangeable chamber and partition halves in- 3,331,3fi2 Patented July 18, 1967 cluding the sleeve means forming part of the central passage.
  • an iris diaphragm consisting of a plurality of laminae so that it can be closed radially inwardly from the joint of the annular partition.
  • the hollow cylinder which forms part of an impeller including a hub, is suitably crosswise cut through up to the impeller hub within the range of movement of the laminae, thereby to provide a gap corresponding in width to the thickness of the laminae so that the iris diaphragm in its initial position is completely enclosed by the annular partition and in its operative position simultaneously closes the peripheral air inlet and air outlet openings as well as air intake and exhaust openings in the central sleeve.
  • FIG. 1 is a section through the ventilating device according to the invention.
  • FIG. 2 is a section through the ventilating device embodying a hood covering it outwardly
  • FIG. 3 is a section through the ventilating device embodying a built-in iris diaphragm.
  • FIGS. 1 to 3 embodiments of the ventilating device of the invention employs an impeller system drivably mounted on an electric motor 13, 13 provided with reinforcing ribs 17, 17
  • This impeller system comprises inner and outer vanes or blades 14, 14 and 16, 16 respectively, inclined in opposite directions for opposite thrust performance.
  • the inner blades 14, 14 carry fixed to their'tips a concentric open hollow cylinder 15, 15 forming an impeller.
  • the outer surface of the cylinder 15, 15 carries the outer blades 16, 16 arranged for rotation in an annular chamber 25, 25 defined by walls 26, 26 and concentrically surrounding the impeller system.
  • the walls 26, 26 of the chamber 25, 25 are formed with a constriction coming close within the reach of the end faces of the hollow cylinder 15, 15 and then are bent outwardly to form a sleeve 10, 10 affording a central passage provided with air intake and exhaust openings 11, 11 and 12, 12 respectively, for the inner blades 14, 14
  • In the air intake opening 11, 11 the driving motor 13, 13 is fixed in a concentric position.
  • FIG. 1 embodiment of the ventilating device and adjustable louver 27 is arranged externally over the exhaust opening 12.
  • the chamber 25, 25 as well as the annular partition 24, 24 may be split along the transverse central plane so as to form respectively two identical interchangeable chamber halves and partition halves.
  • the annular partition thus can be easily secured in place in a corresponding, i.e. preferably circular, aperture in a window pane 22 and form, for example, the supporting frame of the whole structure detachably mounting the walls 26, 26 defining the halves of the chamber 25, 25
  • Such supporting frame may, however, also be formed of the chamber halves themselves.
  • the ventilating device is shown to be externally completely covered by a hood 28 hinged to the device at 29.
  • the air stream produced by the concentrically arranged inner blades 14 is conveyed through the inlet openings 19 into the chamber 25 and from there, due to the inverse action of the outer blade 16, through the outlet openings 20 back again into the room to be ventilated.
  • the air stream passes through a filter which may be inserted in a central hub 31 of the hood 28 so as to be located in front of the air exhaust opening 12 in the sleeve '10.
  • the ventilating device will operate in the normal manner, i.e. vitiated air from the room is conveyed to the outside and fresh air from the outside is simultaneously conveyed into the room.
  • slides 32 may be provided so as to be movable in rails 33 along the circumference of the chamber 25 for selectively covering in each case a number of openings 19 and 20 respectively.
  • the air outlet openings 20 outside the room may thus be covered by the slides 32.
  • the annular partition 24 is split in its transverse central plane and provided in its interior with an iris diaphragm 34, 35 which can be closed radially inwardly from the joint of the split partition.
  • the hollow cylinder 15 of the impeller is also transversely cut through up to the impeller hub so that a gap 38 is provided which corresponds to the thickness of the iris laminae.
  • the iris diaphragm 34, 35 is completely enclosed, in its initial position, by the annular partition, whereas in it operative position the oppoiste air passages 19 20 and 11 12 crossing the impeller, are simultaneously closed up to the impeller hub by means of the iris laminae 34.
  • a cam 36 engaging the iris has to be operated by means of a pull cord 37 secured thereto.
  • the annular chamber of the described ventilating device may, moreover, also incorporate preferably interchangeable inserts, for example in the form of slides, prepared with scent extracts, disinfectants or the like. Such inserts may also extend partly or completely circularly through the annular chamber.
  • heating elements ultraviolet low pressure burners or the like in the annular chamber 25 of the device.
  • Provisions of the foregoing kind enable the air entering from outside to be selectively filtered, climatized or appropriately enriched, according to the insert chosen in each case.
