BACKGROUND OF THE INVENTION
This disclosure relates generally to a toilet vent system and method. In one embodiment, this disclosure relates to said toilet vent system and method.
Various methods of ventilating a toilet and/or a room containing a toilet have been tried and are well-known.
In one embodiment, a ventilation system is installed in a ceiling of a room containing said toilet. This approach leaves much to be desired, however. For example, when odorous gases accumulate in a bowl of said toilet, they have no place to go but into the presence of a user of said toilet.
In one embodiment, a fan system is installed in a tank of said toilet. This approach demonstrates that odorous gases do, indeed, make their way from said bowl into said tank of said toilet. However, this embodiment presents various problems. Namely, how to properly clean said odorous gases within said tank of said toilet. Even modern air filters are no match for many of the odorous gases captured in said tank. Further, in several embodiments, said ventilation systems, kept in said tank with water, run on electricity. Accordingly, a risk of electrical shock and personal harm is risked by using said systems.
None of the above inventions and patents, taken either singularly or in combination, is seen to describe the instant disclosure as claimed. Accordingly, an improved toilet vent system and method would be advantageous.

In one embodiment, vacuum source 902 can comprise a fan attached to toilet vent 108 in a fluid connection.
In one embodiment, ballcock assembly 201 can connect to second manifold 302 by attaching coupling 211 to socket 601. In one embodiment, second manifold 302 can connect to first manifold 301 by attaching base coupling 602 to socket 701. In one embodiment, second manifold 302 can connect to snorkel 303 by sliding side portion 320 into second opening 312. As is common in the art, in one embodiment, each of said base couplings can attach to their respective sockets by rotating said base coupling relative to said sockets so as to lock the respective male threaded portions into the respective female portions.
In one embodiment, first manifold 301 can attach to second manifold 302 at bottom 231 through fluid input 103. Thus, in one embodiment, toilet vent 108 can be assembled in tank 101 without creating a new aperture in tank 101 or replacing an existing tank 101 provided fluid input 103 is available. In one embodiment, lower portion 608 can comprise a substantially smooth portion of outer surface 606 of vertical portion 319. In one embodiment, a portion of tank 101 (such as bottom 231) can be held between second manifold 302 and first manifold 301 by pressing lip 609 against an inner surface 904 of tank 101 and pressing lip 709 against an outer surface 905 of tank 101. Thus, in one embodiment, lower portion 608 can extend between inner surface 904 and outer surface 905, and lip 609 and lip 709 can hold a portion of tank 101 around fluid input 103.
FIGS. 10A and 10B illustrate first fluid connection 321 and second fluid connection 323 with an elevated cross-section front view of toilet vent 108 and tank components 200.
In one embodiment, a portion of first fluid connection 321 between third opening 310 and third opening 307 can comprise an outbound fluid passage 1001. In one embodiment, outbound fluid passage 1001 can comprise a fluid passage around middle portion 326, between first end 324 and second end 325 of up rod 322, and inside of both vertical portion 319 and vertical portion 317. Thus, in one embodiment, up rod 322 can be inserted through, but not totally block, a passage inside of vertical portion 319 and vertical portion 317.
Outbound fluid passage 1001 is illustrated with circular arrows around middle portion 326 in FIG. 10A; however, a movement of gases 238 is not restricted to a circular path while in outbound fluid passage 1001.
In one embodiment, a portion of second fluid connection 323 between first end 324 and second end 325 of up rod 322 can comprise an inbound fluid passage 1002. In one embodiment, inbound fluid passage 1002 can travel through fluid channel 812 between first opening 810 and second opening 811.
In one embodiment, gases 238 and sanitary fluid 109 are kept from spilling between first fluid connection 321 and second fluid connection 323 by sealing first end 324 and second end 325 inside of first manifold 301 and second manifold 302. For example, in one embodiment, second end 325 can seal against inner surface 603 by pressing gaskets 808 against inner surface 603. Likewise, in one embodiment, first end 324 can seal against second opening 306 by pressing lip 804 against a portion of lower portion 708 between inner surface 705 and outer surface 706.
Thus, in one embodiment, said toilet vent system and method can facilitate first fluid connection 321 and second fluid connection 323 simultaneously.
FIGS. 11A and 11B illustrate an unfilled configuration 1101 and filled configuration 1102 in an elevated cross-section front view of tank 101 with tank components 200 and toilet vent 108. As is well known in the art, toilet 100 can comprise an at-rest stage, a flushing stage, and a refilling stage. Further, said flushing stage and said refilling stage can be referred to together as a non-at-rest stage. Likewise, it is well known that while in said at-rest stage sanitary fluid 109 is typically not flowing between tank 101 and bowl 102. While in said flushing stage, sanitary fluid 109 is typically flowing between tank 101 and bowl 102. Finally while in said refilling stage, sanitary fluid 109 is flowing into tank 101 through fluid input 103 and ballcock assembly 201, or similar; wherein, sanitary fluid 109 is typically no longer flowing between tank 101 and bowl 102.
Unfilled configuration 1101 can comprise sanitary fluid 109 at one of a plurality of unfilled levels 1103. Filled configuration 1102 can comprise sanitary fluid 109 at a filled level 1104.
In one embodiment, toilet vent 108 can selectively regulate a removal of gases 238 from tank 101 as toilet 100 transitions between said at-rest state and said non-at-rest stages. For example, in one embodiment, first fluid connection 321 can comprise an open-configuration and a closed-configuration. In one embodiment, said closed-configuration can comprise a portion of said first fluid connection 321 blocked to prevent a fluid movement within first fluid connection 321. In one embodiment, said open-configuration can comprise first fluid connection 321 without a hindrance to said fluid movement within first fluid connection 321. In one embodiment, a portion of floating vent 304 can comprise said hindrance to said first fluid connection 321. In one embodiment, first fluid connection 321 can comprise said open-configuration when toilet 100 is in said at-rest stage. Thus, in one embodiment, gases 238 can flow through first fluid connection 321 in said open-configuration from vent 316 to third opening 307. Further, in one embodiment, vacuum source 902 can pull gases 238 through first fluid connection 321 when first fluid connection 321 is in said open-configuration. Likewise, in one embodiment, first fluid connection 321 can comprise said closed-configuration when toilet 100 is in said non-at-rest configurations. Thus, in one embodiment, neither gases 238 or sanitary fluid 109 can flow through first fluid connection 321 while toilet 100 is in said non-at-rest configurations.
FIGS. 12A and 12B illustrate an unfilled configuration 1101 and filled configuration 1102 in a perspective cross-section front view of tank 101 with tank components 200 and toilet vent 108.
FIGS. 13A and 13B illustrate an unfilled configuration 1101 and filled configuration 1102 in a perspective cross-section side view of floating vent 304 in tank 101. In one embodiment, floating vent 304 can move to cause first fluid connection 321 to transition between said open-configuration and said closed-configuration. In one embodiment, sanitary fluid 109 can regulate whether upper portion 315 of floating vent 304 blocks first opening 311 of snorkel 303. For example, in one embodiment, filled level 1104 can comprise sanitary fluid 109 enclosing float chamber 408 along a bottom opening 1301 and thereby applying an upward force 1302 on floating vent 304 and, thus, open said vent 316 and first opening 311. Likewise, in one embodiment, unfilled levels 1103 can relieve said upward force 1302 and thereby allow floating vent 304 to fall and thereby close first fluid connection 321 by blocking first opening 311 with upper portion 315 of floating vent 304. That is, in one embodiment, a buoyant portion of floating vent 304 can apply upward force 1302 to floating vent 304 to open said first fluid connection 321 or to remove upward force 1302 to close said first fluid connection 321. In one embodiment, float chamber 408 can comprise said buoyant portion of floating vent 304.
