Definitions

  • the present invention relates to an odor extractor apparatus to be installed in a toilet, particularly to the type of toilet assembly that has both a bowl ( 3 ) and a water tank ( 2 ).
  • this invention uses a mechanical fan ( 9 ) to force the gases through an exhaust pipe ( 12 ), as other inventions do, it does it by an innovative basic architecture. In essence it comprises an exhaust system activated by the user presence, plus a water-air duct segment ( 1 ) inserted between the water tank ( 2 ) and the bowl ( 3 ). This duct segment ( 1 ) also presents an output ( 7 ) that allows the unpleasant gases but not the water, to flow into the aforementioned exhaust system.
  • This apparatus may well be retrofit to used toilets in the field or acquired pre-installed to factory new units.
  • D1 and D2 have an odor collecting device assembly (item 20 in D1, item 12 in D2) in their basic architectures, aimed to suck polluted air.
  • D2 also has a skirting (component 28) to allow for a more elevated toilet seat.
  • the present invention has a completely different approach, an architecture that does not require such assemblies to achieve its exhaust goal. It is innovative compared to D1 and D12 or to any other solution to date. It relies on the flushing orifices already present on the bowl ring to grab the air and also relies on the duct segment ( 1 ) added between the water tank ( 2 ) and the bowl ( 3 ) to extract the air (air-water separation by force of gravity).
  • D2 skirting—odor collecting assembly—air duct—fan—exhaust duct.
  • the duct segment ( 1 ) in the present patent is not an air sucking assembly as those existing in the aforementioned prior art, instead it is a split device for the air already sucked. Air collection is performed by the orifices already existing in the bowl for flushing purposes that then become dual function orifices.
  • the present invention uses a completely different inventive principle, based in a configuration that uses the hydraulic flushing structure of the bowl to perform air suction as well, instead of creating a whole new separate structure for this function.
  • Advantages over the prior art are obvious, both from the functional as from the aesthetical standpoints.
  • Aesthetic advantages refer to the environmental visual impact and to the standardization/harmonization with the other toilet components.
  • the present invention has a meaningful advantage concerning the cross section of the air ducts.
  • Exhausting airflow performance is a function of the cross section of the ducts and the fan power. The smaller the cross section, the larger the fan power required to achieve the same airflow.
  • the dimensions of the water flush system are large enough to provide a good air flow for a midsized fan. It results in lower noise level thus increased user comfort.
  • Concerning D2 it was required to move up the toilet seat and use a skirting to enlarge air collecting assembly cross section. Performance is thus dependent on the toilet seat height and skirting to achieve acceptable venting, meaning it needs at least this extra assembly to reach performance.
  • the present invention has a lower component count compared to D1 and D2, the components are grouped in a more compact form factor and are more organically integrated, seamless, with fewer joints, concavities and corners. This structural simplicity leads naturally to easier making and installation.
  • the duct segment ( 1 ) of the present invention is made out of the same material of the water tank, being suitable to be manufactured by the same manufacturer using the same technology.
  • both D1 and D2 require toilet seat modifications, not required by the present invention.
  • the toilet seat is usually a user's personal choice item, among many options available. This choice is limited to the integrated toilet seat type offered, when D1 or D2 solutions are employed.
  • SANITIZATION The present invention exhibits clear advantages against D1 and D2 both concerning inner and outer sanitization. Concerning internal components, since air and water flow through the same ducts, they become self-cleaning, particles of nasty substances being removed at each water flush.
  • AESTHETICS ADVANTAGES Concording aesthetics, the present invention, when added to toilets in the field, presents much less visual impact than D1 and D2.
  • D1 and D2 might be added to toilets in the field, one can clearly note they do seem like parts strange to the set. Only the present invention integrates seamlessly to the toilet set. The end result can easily be seen at the main drawing in each of the patents: even at a glimpse, D1 and D2 show up as a toilet set to which an apparatus was added; while the present invention integrates itself seamlessly to the set. This is a very important factor affecting consumer's buying decision making, because even a very effective apparatus may not be bought for aesthetic reasons.
  • the duct segment ( 1 ) in the present invention is made out of the same material as the toilet bowl ( 3 ) and tank ( 2 ), (usually ceramics) and can be offered in the same color and finishing. For its position and form, this duct segment ( 1 ) presents itself as a natural extension of the tank ( 2 ), undistinguishable of the tank at a first glimpse.
  • the duct segment ( 1 ) can be manufactured by the same manufacturer of the toilet set, granting seamless form fit free from corners and steps that might degrade its performance and aesthetics. Also, a perfect color match for the duct segment ( 1 ) to the toilet set can be expected from the manufacturer of both items.
  • ducts 11 and 12 and the fan housing due to their form and position have less visual impact. Besides, they can be made in the same color and finishing of the junction segment ( 1 ), same as the bowl ( 3 ) and tank ( 2 ), allowing them to be made by the same manufacturer, achieving the aforementioned seamless fit and pattern.
  • the overall end result has low negative visual impact, accounting for big business expectations.
  • patent U.S. Pat. No. 5,839,127 also sucks gases from the flushing holes, but as the gases flow downstream through relatively narrow passages, since originally made as water overflow drain, the efficacy of gas removal is comparably small.
  • Another shortcoming is the relative difficulty to retrofit units in the field, since parts changes inside the tank are required.
  • valves require sealings, costs and may fail.
  • FIG. 1 Perspective view of the whole set, as installed.
  • FIG. 2 Front and cut view of the duct segment ( 1 ) and the water tank ( 2 ).
  • FIG. 3 Top view of the duct segment ( 1 ).
  • FIG. 4 Schematic view of the siphon ( 16 ).
  • the invention comprises an exhaust system activated by the user presence, plus a water-air duct segment ( 1 ) inserted between the water tank ( 2 ) and the bowl ( 3 ).
  • This duct segment ( 1 ) also presents an output ( 7 ) that allows the unpleasant gases but not the water, to flow into the aforementioned exhaust system.
  • Said duct segment ( 1 ) is a hollow chamber ( 4 ) that besides the water input ( 5 ) and the water output that is also the air input ( 6 ), has an air vent output ( 7 ) (to outside the room).
  • Two vent outputs ( 7 ), one at each side of said junction segment ( 1 ), can be fitted so that the more convenient vent side can be selected to install the ventilation parts. In this case, the unused output is blocked by a cap ( 8 ).
  • Ventilation is mechanically forced by means of a fan ( 9 ) installed anywhere downstream in the exhaust duct, also connected to the power outlet by a power cord ( 10 ).
  • One side of the fan ( 9 ) is connected to the chamber ( 4 ) by the duct ( 11 ) and, the other side is connected to a duct ( 12 ) that guides the air out of the room.
  • the fan ( 9 ) must be located above the maximum possible flood water level in the chamber ( 4 ), ideally above the tank water surface level, thus assuring that the flush water does not reach it.
  • the present invention comprises a siphon (inverted “U”) ( 16 ) upstream the fan ( 9 ) to force the gases flow above the flood level thus preventing water from reaching the fan ( 9 ).
  • a siphon inverted “U”
  • the fan ( 9 ) is integrated to the duct, its output duct ( 12 ) moves to the desired direction to ease the installation.
  • Said duct segment ( 1 ) is hydraulically connected to the water tank ( 2 ) above and to the toilet bowl ( 3 ) below, by means of sealing rings ( 14 ) same as those that seal the tank ( 2 ) to the bowl ( 3 ).
  • Said duct segment ( 1 ) has dimensions that match those of the tank ( 2 ) and bowl ( 3 ), making it possible to transfer the weight of the tank to the toilet bowl, as well as aesthetic harmonization.
  • the fan ( 9 ) may be turned on either by a manual switch or by a presence sensor ( 15 ) as soon as a user is detected.
  • the presence sensor ( 15 ) can also have a timing function to keep the fan ( 9 ) turned on for a period of time after use, granting complete exhaustion.
