<p>A ventilation system for removing odours from a toilet of the kind having a seat (10) supported on a bowl (114), the seat (10) being ducted such that there are inlet ports (22, 24, 26, 28) located at the inner rim of the seat (10) for receiving the odours and an outlet port (30) at the rear of the seat (10) for transferring the odours out of the ducting (21) in the seat (10) and into piping (18). The piping (18) is connected to an air extractor (20) and, under the suction effect of the air extractor (20), the odours are drawn away from the toilet to a circulating air environment where they can be dissipated. Each of the inlet ports (22, 24, 26, 28) have an inlet duct portion (32) which faces toward the rear of the seat (10) when the seat (10) is laid flat, and downwardly when the seat (10) is upright.</p> |
