VENTILATED TOILET

摘要

Toilet bowl ventilating apparatus is described in which the bowl is ventilated automatically in response to the weight of a user sitting on the seat. This is achieved by locating a resilient pressure switch on the underside of the seat which when closed by the user's weight, actuates an extraction fan which draws gases from the toilet bowl through a vapour inlet device located at the rear of the toilet seat and bowl, and through flexible conduits to a vent pipe where the gases are eventually discharged to atmosphere. The vapour inlet device is secured to the toilet bowl via the seat bolts and has a low profile. The apparatus is suitable for domestic use with a conventional electrical supply or for field use where no a.c. supply is present.
