  • the seat 3 is provided with a lip 6 integral with the under side of the seat 3.
  • the hinge 4 is substantially cylindrical and is apertured.
  • the seat 3 is integral with that part of the hinge 4 that is apertured and lifting the seat 3 as can be seen clearly in Figure 1 alters the position of the hinge aperture (in other words, rotating the seat 3 about the longitudinal axis of the hinge 4). It will also be noted that the apertured portion of the hinge 4 that is integral with the seat 3 is also free to rotate about the hinge block 5 in a conventional manner.
  • the hinge 4 essentially comprises three components, an inner portion that is integral with the seat 3 and is apertured, that is free to rotate about the longitudinal axis of the hinge 4 and two outer non apertured components 36 that are also free to rotate about the longitudinal axis of the hinge
  • an inner cylindrical tube 7 is permanently fixed or secured in position via conventional fixing means such as glue or welds but it will also be noted that the tube 7 is apertured. In alternative embodiments, the tube 7 may be demountable and fitted into place with for example, a grub screw.
  • the size of the aperture is larger than the hinge aperture but as can clearly be seen in Figure 1, when the seat 3 is in the lowered position, the hinge aperture is wholly enclosed by the tube aperture providing a pathway denoted by the letter "B".
  • Figure 1 also illustrates the seat in a raised position and as can be seen, once the seat is raised, the hinge aperture is completely out of phase with the tube aperture closing the pathway denoted by the letter "B".

  • the resiliently flexible material 14 and the mating action of the lips 6 with the hinge block 5 when an individual sits on the seat 3, substantially, the only means of air-flow across the under side of the seat 3 is through the "mouth" of the "head” of the under side of the seat 3.
  • Figure 5 shows the toilet seat 1 replete with lid 2, seat 3, hinge 4 and hinge block 5, the lid 2 being in the "closed” position.
  • the lid 2 is provided with two rubber teats 8 so positioned to come in contact with either side of the top surface of the seat 3 so that the lid 2 does not mar or chip the top surface of the seat 3 if the lid 2 is inadvertently "dropped” down on to the seat 3.
  • the clearance between the lid 2 and the seat 3 as a result of the teats 8 is less than 1 cm and in this embodiment is approximately 5 mm.
  • the lid 2 is also provided with a recess 9 at its head to enable an individual to lift the lid 2 with ease by inserting one's fingers under the recess 9. Although not clearly illustrated, the head of the lid 2 passes beyond the mouth of the seat 3 so that when "looking-down" on the lid 2 in Figure 5, the mouth of the seat 3 cannot be seen at all.

  • FBCM fan box cover mounting 42
  • the fan box cover 44 is substantially square in shape and is so sized as to cover substantially exactly, a standard sized bathroom or toilet tile, so that when fitted to the interior wall 41 of the bathroom or toilet, it remains substantially "flush” with the overall decor of any tiling that may be present as only one complete tile needs to be removed and replaced with the fan box cover 44.
  • the FBCM 42 is a hollow substantially square tube in use provided with a shoulder running along the entire inner periphery of the tube that the fan 43 sits in, when in use.
  • the occurrence of the shoulder is substantially parallel with the exterior terminal edge of the FBCM 42, (which contacts the interior wall 41 of the bathroom or toilet in use).

  • PVC sleeving is used in preference to any other plastics or non-plastics sleeving as it has extremely good insulation properties and it tends to minimise condensation and damp ingress wherever it is used in this manner.
  • the hollow portion of the FBCM tube 42 creates an essentially static "air-pocket" within the hollow that surrounds the fan 43 when the apparatus is in use and this hollow portion is designed for a purpose.
  • This hollow portion serves as a housing to hide much of the electronic wiring 45 associated with the fan 43, the wiring 45 sitting extremely neatly within this hollow.
  • the hollow portion also serves the purpose of reducing the noise level of the fan 43 when in operation as air, trapped in this manner (by the hollow) is a very good noise insulator.
  • the hollow also serves the additional purpose of hiding any possible interior edge fractures of the wall 41 once an aperture has been drilled through it, provided of course that the fracture is not greater than the distance "X" shown in the lower drawing of Figure 9.
  • the upper drawing in Figure 9 shows the sloping portion of the fan box cover 44 to be a circular cone in shape.
  • the slope of the cone with respect to the mouth 46 of the fan box cover 44 is substantially
  • the fan box cover 44 is made from Acrylonitrile Butadiene Styrene ABS, as it has been found that this particular plastics material has one of the best sound absorbing properties of any plastics material in the market place. Furthermore, it lends itself extremely well to the application of paint which "takes” to this form of plastics material extremely well.
  • the fan box cover 44 is fitted to the FBCM 42 through the use of conventional "arrow-clips" 47.
  • Figure 10 illustrates the means of linking the toilet seat 1 to the fan box cover 44 in use which is through some piping 48, the outer diameter of which, at both its proximal (that end nearest the toilet seat 1) and its distal (that end nearest the fan box cover 44) end is such that they respectively slide into one end of the hinge 4 and into the mouth 46 of the fan box cover 44 in a friction-push-fit type arrangement.
  • This piping 48 forms the remaining essential part of the extraction device and in this particular embodiment is also made from ABS.
  • the fan 43 or "air mover” is model No FN12B3, manufactured by Comair Rotron
  • the fan 43 was chosen for its quality, long life, low voltage, safety records, low maintenance and quiet operation and provides more than adequate airflow tests as conducted by "OEM Automatic” (see Appendix 1).
  • the fan 43 in use, is operated or actuated by a passive infrared (PIR) sensor 62.
  • PIR passive infrared
  • the PIR sensor 62 is again, an "off the shelf item. In fact, it is the “Reflex” PLR sensor 62 manufactured and sold by "Texecom", a trading style of "Texecom Limited”.
  • the requirements of the PLR sensor 62 for its use as part of this apparatus are as follows:
  • Figure 11 is a circuit diagram of a power supply suitable for use in the extraction device.

A current of air through the mouth of the under side of the seat 3 across the under side of the mouth of the seat 3 through apertures 10 and 11 via the pathway "B" will then ensure that no noxious odours escape the toilet bowl 50 when the toilet seat 1 is in use.
  • the extraction device is operated via the light switch in the toilet or bathroom, when the seat 3 is in its raised position, a problem may occur with the extraction device if one end of the tube 7 is sealed. In other words, there will be no pathway "B" available to the extraction device and as a result, this may put the extraction device under undue "stress" and may damage the system. Therefore, in an alternative embodiment (not illustrated) the sealed end of the tube 7 could be provided with a valve that comes into operation if the seat is raised and the extraction device is on allowing a passage of air through the tube 7, thereby not damaging the extraction device if it is on.

  • the chosen unit of mass flow was Litres per Second (1/sec)
  • Linear velocity reading was in Millimetres per Second (mm/sec)
  • To convert from linear velocity to mass flow the following formula was used
  • the selected fan is designed for continuous duty life of 60,000 hours (6 85 years) at 25 Degrees C
