Abstract
A toilet with ventilation apparatus has an open air passageway from a bowl through a rim, flush valve and overflow tube to an air space above water in a tank, and a conduit from the air space to outside a room where the toilet is located.
Description
- The present invention relates to ventilation apparatus, and more particularly, to the type that is installed in a toilet.
- Many toilet ventilators have been invented in the past, none of them included apparatus that ventilates the air space that exists above the water level in the tank in a conventional toilet, which air space is connected directly through the overflow tube to the water outlets in the rim of the toilet bowl, where noxious odors emanate.
- For example, U.S. Pat. Nos. 6,219,853 and 5,906,009 ventilate from below the flush valve. U.S. Pat. Nos. 5,991,933 and 5,839,127 ventilate through specially-extended overflow tubes. U.S. Pat. Nos. 5,940,893 and 4,590,629 force air from the overflow tube down into water in the tank. U.S. Pat. Nos. 5,718,005, 6,279,173 and 3,681,790 remove air directly from the overflow tube. U.S. Pat. No. 4,583,250 requires a specially-adapted overflow tube. U.S. Pat. Nos. 6,260,215 and 6,233,750 remove air directly from the bowl.
- Thus, none of these prior art systems utilize to the greatest extent possible the air passageways that are already built into conventional toilets in the simplest manner, by simply ventilating the air space in the tank to a conduit outside the room where the toilet is located.
- It is one of the main objects of the present invention to provide an apparatus that extracts gases discharged by users of a toilet from the air space in the toilet tank.
- It is yet another object of this invention to provide such a apparatus that is inexpensive to manufacture and maintain while retaining its effectiveness.
- Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.
- With the above and other related objects in view, the invention consists in the details of construction and combination of parts as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which:
-
FIG. 1 is a partially broken away side view of a first embodiment of the present invention. -
FIG. 2 is a partially broken away side view of a second embodiment of the present invention. -
FIG. 3 is sectional view taken along lines 3-3 ofFIG. 2 . -
FIG. 4 is a partially broken away front view of a third embodiment of the present invention. -
FIG. 5 is a partially broken away side view of the second embodiment of the present invention illustrating air flow. - Referring initially to
FIG. 1 ,toilet 10 is conventional in every respect with the exception ofconduit 12 inlid 14. Thus,toilet 10 has an open air passageway from thebowl 16 through therim 18,flush valve 20 andoverflow tube 22 to anair space 24 abovewater 26 intank 28.Conduit 14 passes between from theair space 24 to outside the room where the toilet is located throughhose 30 andfan 32. - Preferably, a
seal 34 is provided between thelid 14 and thetop rim 36 of thetank 28. In many instances, theseal 34 may be omitted if thelid 14 andtop rim 36 are adequately air-tight without a seal. An advantage of this embodiment is that it may be incorporated in an existing installation by merely replacing the preexisting lid with a new lid that has theconduit 12. - Referring now to
FIGS. 2 and 3 , in a first alternate embodiment all the conventional toilet parts are the same as inFIG. 1 . The difference in this embodiment is that theconduit 50 is now integrally formed in aback wall 52 of thetank 54.Conduit 50 has anopen inlet 56 above thewater level 58, and anoutlet 60 at thebottom conduit 50. Hose 62 passes throughwall 64 of the room and is connected tofan 66. - An advantage of the integrally formed conduit is that it is essentially maintenance-free and as durable as the material from which the rest of the toilet is made. Moreover, the
outlet 60 is hidden from view in positions from which users normally approach the toilet. A further advantage, compared to the embodiment ofFIG. 1 , is that the tank lid may be easily removed for maintenance of the internal parts of the toilet. - Referring now to
FIG. 3 , again, all the conventional toilet features are present, except aconduit 80 is atube 82 passing through anaperture 84 in abottom wall 86 of the tank.Suitable fittings 88 prevent leakage.Open top 90 is abovewater level 92, andhose 94 passes outside the room where the toilet is located. - In operation, as best shown in
FIG. 5 , air is removed frombowl 16 to thehose 62 as shown by the arrows. - Whereas, the present invention has been described with respect to specific embodiments thereof, it will be understood that various changes and modifications will be suggested to one skilled in the art, and it is intended to encompass such changes and modifications as fall within the scope of the appended claims.
