Definitions

  • the present invention relates to a fan adapted for use as component of a ventilation system for a building or a part thereof, for example a dwelling, which fan comprises:
  • Such a fan is known from DE-U-86 26 016 wherein a coupling of a fan in a housing including a snap-coupling is described. For unlocking the snap-coupling a specially designed tool is necessary. Both during installation and exchange of the motor and the rotor a separate cover also has to be installed.
  • the present invention provides a fan adapted for use as component of a ventilation system for a building or a part thereof, for example a dwelling, which fan comprises:
  • the fan housing including the air inlet and air outlet conduits can be installed first by a fitter while an electrician can later on install the motor, rotor and cover easily at the same time closing off the fan. Also the exchange of the motor and rotor can easily be executed although a non-professional will not easily understand in which way the rotor and motor can be removed.
  • Figures 1, 2, 3, 4, 5, 6, 7 and 10 all relate to a fan 1 which is adapted for use as component of a ventilation system for a dwelling.
  • the fan 1 comprises a housing 3 enclosing a cavity 2.
  • the fan further comprises a motor 4 which drives for rotation a rotor 6 carrying air displacement blades 5, which blades 5 are accommodated in the cavity 2.
  • the fan further comprises three air inlets 7, 8 and 9 which are each adapted for coupling to an air intake conduit 10 (see figure 5) and debouch into cavity 2.
  • the fan further comprises an air outlet 11 which is adapted for coupling to an air outlet conduit (not drawn) and connects onto the cavity 2.
  • the air inlets 7, 8, 9 lie in one principal plane.
  • the air outlet 10 connects onto an outlet duct 16 extending substantially tangentially of the substantially rotation symmetrical cavity.
  • Caps 17, 18 and 19 can be used to close two of the associated air inlets 7, 8 and 9 respectively, whereby only one air inlet is used. If required, more than one of the air inlets 7, 8 and 9 can also be used simultaneously.
  • the motor 4 directly supports the rotor 6 with the blades 5.
  • the housing 3 has an opening 21 through which the cavity 2 is accessible from outside.
  • the motor 4 is supported by a cover 22 with which the opening 21 can be closed.
  • This cover 22 can be coupled to the edge 23 of opening 21 by means of coupling means embodied such that cover 22 can be coupled to the opening edge 23 without use of a tool.
  • coupling means several examples of which will be described hereinbelow, only form part of the edge 23 and the cover 22.
  • Figures 1, 2 and 6 relate to the embodiment according to the present invention in which use is made of a snap-coupling.
  • the housing is supported on for instance a wall 29 (see for example figure 3) via a base 30.
  • Base 30 fixes the insert 15, which is manufactured from polystyrene foam material, in the housing 3.
  • This housing 3 bears on its corner points corner fastening elements 31 each having slotted holes 32 and 33 extending in two mutually perpendicular directions and an elongate support 34 for the electricity cable 20 which can be fixed in the manner shown in figure 10 to the support 34 by means of a screw 35.
  • Fastening screws 36 (see figure 10) can be placed through slotted holes 32, 33 to fix the housing 3 on the bearing construction, for instance the wall 29 shown in figure 3.
  • a generally cross-shaped structure 37 is formed on the base 30. This serves to prevent whirling in the cavity 2 and is also dimensioned such that it positions the insert 15 correctly in housing 3.
  • a base 38 which carries a separate cross 39 of acoustic damping material, for example of mineral fibres.
  • Figure 7 shows that the motor 4 can be placed in snapping co-action with recesses 42 present in the cover 22 by means of snap-lips 40 with oblique leading surface 41.
  • the screw-driver 27 By inserting the screw-driver 27 into the interspace between the peripheral wall 43 of the cover 22 and a snap-lip 40 the coupling between the snap protrusion 44 present thereon and the corresponding recess 42 can be broken whereby the motor 4 with the rotor 6 carrying the blades 5 can be separated from the cover 22, for example for replacement of the motor or for inspection purposes.
  • the housing 3 consists preferably of plastic and can be produced with any suitable manufacturing method, for instance injection moulding.
  • Figure 5 shows the manner in which an air inlet or outlet conduit can be connected to an air inlet or air outlet.
  • the air inlet conduit 10 fits round the zone of the air inlet 7 protruding furthest outward. An air-tight connection is ensured by means of a strip of sealing adhesive tape 45.
  • Figure 3 shows that the cable 20 shown in figure 1 and protruding from the peripheral wall 43 of cover 22 extends in the fitted situation of cover 22 between the inner peripheral wall 46 of opening 21 and the outer peripheral wall 43 of cover 22.
  • the cable 20 Via a recess 47 the cable 20 is trained outward, where as according to figure 10 it can be connected to support 34 by means of screw 35, being relieved of tension with a clamping strip 48.
  • the recess 47 is preferably embodied such that cable 22 fits clampingly therein.
  • the interspace between the peripheral walls 43 and 46 is also preferably dimensioned such that cable 20 fits clamping therein with some force.
  • the bases 30 and 38 can be coupled to housing 3 with snap lips 49.
  • FIGS 8 and 9 show respective fans 49 and 50, whereof the respective covers 51 and 52 are coupled to housings 55 and 56 respectively with a threaded coupling 53 and a bayonet fitting 54.
  • the fans 49 and 50 can otherwise have the same structure as described above.
