Internally vented toilet with dedicated exhaust system

摘要

This invention pertains to an internally exhausted toilet bowl which employs basic principles of fluid flow to provide reliable, more efficient, and more effective removal of noxious toilet odors while reducing energy consumption when compared to current art. This is accomplished during all conditions of normal operation. In case of toilet overflow or condensate buildup, the impact on the vent exhaust path from these upset conditions can be resolved easily, and normal operation can be restored without damage to any components. Additionally, this invention includes maintenance features that would provide means for back flushing the annulus vent line and orifices if clogging ever were to occur.

主权项

1. A toilet system comprising:
a toilet bowl having a rim jet annulus located circumferentially inside a portion of a toilet rim disposed above and around a periphery of the toilet bowl wherein the rim jet annulus has a plurality of rim jet orifices for introducing water into the toilet bowl; an annular vent passage which is separate but located circumferentially inside and concentric with the rim jet annulus of the toilet rim of the toilet bowl, the annular vent passage having a plurality of vent exhaust orifices located at an inner radius of the annular vent passage and positioned above the rim jet orifices to avoid communication of water from the plurality of rim jet orifices into the annular vent passage via the plurality of vent exhaust orifices; and the annular vent passage connecting at the back vertical plane of the toilet bowl to avoid interference with the rim jet annulus, to an annular exhaust vent line wherein the annular exhaust vent line slopes downward from the back vertical plane of the toilet bowl to a low point where there is located a low point drain line and a low point drain valve at the bottom of the low point drain line, thereafter, the annular exhaust vent line continues with a constant slope upward for a distance to join with an enlarged parent exhaust line wherein the parent exhaust line is in communication with a bypass branch line upstream of a vent exhaust fan upstream isolation valve located upstream of a vent exhaust fan and the parent exhaust line outlet.
