Device for venting odors from a toilet bowl

摘要

The present disclosure is directed to an adapter and base plate that may be retrofitted to existing industry standard toilets to provide a capability to vent foul odors from bodily waste deposited into the toilet bowl. The toilet includes a bowl having flush holes disposed around a rim of the bowl for discharging water into the bowl, a water tank for containing a volume of water sufficient to cause the toilet to flush when the volume of water is discharged into the bowl, a flush and refill mechanism for flushing and then refilling the toilet, the flush mechanism controlling a flush valve that covers a drain at the bottom of the water tank. The bowl also includes a water feed conduit connecting the drain to the holes around the rim of the bowl. The adapter is fitted between the water tank and bowl with a first opening receiving the flush valve and a second opening connected to an exhaust fan by plumbing. By means of a gap between flush valve and adapter's first opening exhaust fan is in fluid communications with flush holes disposed around the rim of bowl. Activation of exhaust fan will draw foul odors through flush holes, water feed conduit, adapter, plumbing, and exhaust fan to an appropriate outside destination. Adapter, being of simple construction with angled sides so as to prevent the pooling of water, is incapable of supporting the water tank thus requiring a base plate that surrounds the adapter to support the water tank. The base plate may be translucent to allow LED lighting mounted to adapter to be cast about the bowl.

主权项

1. A ventilated toilet comprising:
a bowl having a passage about the rim of the bowl with a plurality of openings for the discharge of water into the bowl the passage receiving water for discharging into the bowl from an opening at the rear of the bowl the openings in fluid communications by means of the passage; a water tank containing a volume of water sufficient to cause the toilet to flush when the volume of water is discharged into the passage; a flush mechanism for flushing the toilet, the flush mechanism controlling a flush valve that covers a drain at the bottom of the water tank the flush valve further comprising a shank that protrudes beyond the drain and registering with the opening in bowl to receive water for discharging into the bowl the flush valve secured to water tank by shank nut threaded onto shank; a refill mechanism for refilling the water tank; an adapter suspended between the bowl and water tank the adapter:
being generally elongated in shape defining a cavity throughout with first and second openings,symmetrical about its longitudinal axis,first opening having an annular structure to receive the shank the annular structure further containing a flange to support a gasket to seal the joinder of annular structure to shank nut and sloping surface to support a gasket to seal the joinder of annular structure to bowl the annular structure not in contact with either the water tank or bowl,second opening connected by plumbing means to an exhaust fan thereby in fluid communications with exhaust fan, andinterior planes of such slope to cause water present within the adapter to flow out of adapter through first opening; and a base plate of a form to enclose the front, left, and right sides of the adapter and the elongated bolts used to mount the water tank to the bowl the base plate to support the water tank and remove loading forces on adapter.
