Definitions

  • the present invention relates, as is indicated by its title, to an air extraction system for toilets whose aim is to prevent possible smells produced during use of the toilet from extending to the room where the toilet is housed.
  • Some of these systems carry out the air suction by means of some nozzles coupled to the toilet. These may be deployed in the space existing between the lid and the rim of the toilet in which case a planar configuration is adopted or in some orifices defined for the purpose in the zone behind the toilet.
  • the nozzle is not fixed in a stable manner to the toilet, and may be displaced or even free from it. This makes it awkward, especially during cleaning tasks.
  • Another of the systems available considers sucking air inside the cistern and inside a zone above water level; the aim of this system being to extract odours from inside the toilet by means of an overflow that connects the aforementioned zone with the inside of the toilet, as this overflow passes over the closure defined by the flushing device of the cistern.
  • This system does not satisfactorily resolve the problem of smells either, due partly to the small capacity of the overflow duct and partly because the lid does not make an airtight seal over the cistern, allowing air in from outside through the gaps between the two.
  • This system has some constructive characteristics oriented towards allowing its installation both in new toilets and in toilets that have already been installed. It assures sufficient suction to prevent the propagation of smells to outside the toilet system.
  • the system comprises an extraction fan located within or outside the cistern.
  • This fan is provided with control means and is connected to a suction pipe and an impulsion pipe; the suction pipe is connected either directly or by means of some auxiliary pieces to the orifice defined in the toilet allowing the entrance of water from the cistern, in such a way that said orifice serves both to allow the passage of water and for air extraction, with a possible automatic device preventing back-flow.
  • the suction pipe has at least an initial vertical stage or with an inclination large enough to prevent the water from the flushing of the cistern from reaching the fan that provides the suction, for example with an anti-flow back valve.
  • the impulsion pipe through which the air sucked by the fan passes can be coupled, as convenient, via a ventilation pipe to the outside or with the scupper pipe, in which case the connection will be made in a zone behind the siphon of the toilet in order to prevent the return of smells to inside the toilet. It may also be provided with a chemical or charcoal filter.
  • connection of the suction pipe is carried out with an auxiliary piece or an integrated piece that is provided with a lower mouth suitable for fixing to the cistern exit, an upper mouth to mount the corresponding closure and flush device and with an additional outlet for coupling said suction pipe.
  • the suction pipe is connected directly to the flush pipe and preferably in the zone nearest to the toilet or by means of a hole expressly drilled in the bowl with an additional piece provided with a suitable detector.
  • air suction from the inside of the toilet is carried out via an orifice defined in the upper rear zone of the toilet, and conventionally used for the entrance of flush water, assuring a correct suction of the smells by the system object of the invention as a result of the strategic position of said orifice.
  • the control means of the fan are composed of an electrical circuit allowing the activation and deactivation of the motor associated with the circuit.
  • the means of activating and deactivating the fan can be composed, by way of example, of a manual or automatic on/off switch, by an on switch and timer that switches it off after a pre-set period of time has elapsed, by a sensor that activates and deactivates it, a speed regulator of the motor, a dry/wet water detection probe and an on or off cell or automatically depending on the pressure that the toilet seat exerts thereon.
  • the system object of the invention considers a suction pipe (1) and an impulsion tube (2) coupled to a fan (3) given the task of sucking the air from inside the toilet (4) via the pipe (1) and forcing it to the outside through pipe (2).
  • Said piece (6) as well as a lower mouth (6a) destined to be coupled to the lower mouth of the cistern and an upper mouth (6b) for coupling of the flush mechanism (7), defines an additional outlet (6c) for coupling the suction pipe (1), carrying out both the suction of the air from the inside of the toilet and the flushing of water from the cistern via the piece (6).
  • the impulsion pipe is connected to a ventilation duct (8) as is represented in figures 1 and 2 or to the scupper pipe itself of the toilet as is shown in figure 4; in this latter case the connection will be made in the zone located next to the siphon, and will be provided with a device or system to prevent back-flow.
  • the suction tube (1) will be connected directly to said flush pipe, without it being necessary to use the accessory piece (6).
