DESCRIPTION OF THE INVENTION
In FIGS. 1 to 6 of the accompanying drawings there is shown an apparatus 10 for removal of odours from a toilet comprising a vacuum motor 12, a filter 14, a hose 16 having a first end 18 and a second end 20, and a switch 22 (see FIG. 3). There is also shown in FIGS. 1 to 3 a toilet 40 comprising a toilet pan or bowl 42, a seat 44 and a cistern 46. Further, there is shown a mains power point 50 from which power for the vacuum motor 12 is supplied. The first end 18 of the hose 16 extends under the seat 44 and into the bowl 42 of the toilet 40. The second end 20 of the hose 16 connects to the filter 14. The vacuum motor 12 is mounted below the filter 14 in communication therewith.
When the vacuum motor 12 is operated, a vacuum is created in the hose 16 such that air is drawn into the first end 18 of the hose 16 from the bowl 42 of the toilet 40, thereby drawing unwanted odours into the hose 16. Air from the hose 16 enters the filter 14 via the second end 20 of the hose 16. The vacuum motor 12 draws the air from the hose 16 through the filter 14 and the filtered air is released through a number of outlets 24 located in a peripheral wall of the vacuum motor 12.
Shown in FIG. 1 of the accompanying drawings is an embodiment of the present invention in which the apparatus 10 has been installed internally within a room. In this embodiment, the filter 14 and the vacuum motor 12 are located within the room which contains the toilet 40. Further, it is envisaged that a fragrant substance or scented filtration layer may be inserted into the filter 14 to deodorise and filter simultaneously the air.
In FIG. 2 of the accompanying drawings, there is shown an embodiment of the present invention in which the filter 14 and the motor 12 are located externally. Like reference numerals to those used in FIG. 1 are used for corresponding components of the apparatus of FIG. 2. The filter 14
