Definitions

  • the invention relates to sanitary devices, such as lavatories and urinals, equipped with incorporated ventilation arrangement.
  • the human excrement consists of three components: Solids (faeces), liq- uids (urine) and gases (unpleasant odour).
  • Solids fraeces
  • liq- uids urine
  • gases unpleasant odour
  • the existing and conventional devices in the market do remove the solids and liquids but are not able to remove the gases.
  • a common problem encountered with any toilet is the unpleasant odour that occurs in the vicinity of the toilet during and after use.
  • the unpleasant foul air so generated tends to pervade the entire room and its nearby areas where the water closet is located.
  • the opening of windows and/or operating of extraction fans do not always sufficiently and quickly remove the foul air in the associated lavatory and urinals spaces.

  • One object of the present invention is to overcome the problem of toilet odour, either in private or public places, by omitting the conventional exhausting arrangement, i.e. ventilator installed normally in the upper parts of the walls or ceiling of the bathrooms or toilets and merging the same with the lavatory or urinal bodies into one.
  • Another object thereof is, in one single small volume (inside the bowl), and only there and nowhere else in the entire bathroom, to create and keep a negative pressure which will inhibit the escape of foul air from sanitary bowl or urinal into the surrounding atmosphere by creating an air curtain between the sanitary bowl and the surrounding atmosphere. From the said volume with negative pressure, all other undesired air and moisture also will be extracted.
  • Still further object of this invention is that the said extraction ducting system is incorporated with the main body of the sanitary devices and is connected to the central ventilation ducting or piping of the room/building in an invisible way.
  • the invention will make it feasible to introduce new generation of more user-friendly sanitary devices being both intelligent and energy saving.
  • a further object of the invention is to create a ventilation system totally in- dependent from the flush system and the waste disposal system, i.e. if the central ventilation malfunctions the sanitary device will still be working as an ordinary device. On the other hand, if the device malfunctions the ventilation of the invention will still work properly.
  • the aim of the present invention is to change and modify the whole concept of sanitary devices, such as lavatory bowls and urinal designs, and to obtain sanitary devices with an air extraction system totally independent from other functions of the device, such as flush water and waste material, which is hidden in the devices without disturbing the shape and the design as developed over the years.
  • the invention comprise an internal air exhaust passage system through which the foul air from the sanitary device is sucked out, for example by the means of a central room/building ventilation system.
  • the said exhaust passage system will be embodied mainly in the free and idle space left between the inner and outer crust of lavatory bowls and urinals.
  • the inlet part of the internal air exhaust passage in the device is in one embodiment arranged as several holes spaced from each other so that the distance between the holes or openings is formed at intervals so that the distance between them differs in relation to the distance from the foul air emanating source.
  • the present invention solves the said problem related to air interaction with the flush water channel and with the waste disposal channel and pipe system by providing a separate and independent air extraction system which is also integrated in the main body of the device.
  • the air ventilation system is also provided with a user parameter sensitive device in order to regulate the flow rate of ventilation air according to pre-programmable ventilation cycles.
  • Air is extracted through an air exhaust passage, which extends and develops within the body volume of device wholly or partly in a parallel position to the water flush channel and wholly or partly following the body shape and form of the sanitary device.
  • the air exhaust passage is connected to an external air exhaust passage, for example a central ventilation system.
  • the connection is performed in a manner according to which the connection point of the two systems is hidden by being covered under the base or behind a rear part of the device in floor or wall installations accordingly.
  • the passage can be either formed as a concealed internal exhaust intermediate volume arranged in between the outer crust and the bowl of the sanitary device with air inlets holes and an air outlet passage.
  • the exhaust intermediate volume is wholly or partly the same volume as the total volume between the outer crust and the bowl of the device.
  • the passage can also be formed as a separate additional volume arranged within the volume between the outer crust and the bowl of the device. In designs without such idle intermediate spaces, required space should be created and included in the device body.
  • the present invention presents a new generation of lavatories and urinals with intelligent optimize ventilation systems.
  • the ventilation system may be either central/continuous or local/occasional. In the both cases, air extraction rate can be minimised and controlled to avoid unnecessary lost of energy, namely avoiding over-ventilation of conditioned air.
