  Toilet ventilation systemUSPTO Application #: 20060085898Title: Toilet ventilation system Abstract: A toilet ventilation system which may be produced as either a permanently installed system or a portable system which may be moved from place to place with relative ease. In the portable system, odors are collected into either an easily installed and removed collection collar which fits within the toilet bowl ring, or ducts within the toilet seat, and then vented through flexible tubing, by means of an impeller fan, to a point outside the room. In the permanent system, odors are collected either through the seat ducts or ducts formed within the rim of the toilet bowl. Venting to the exterior of the room is then accomplished through ducts permanently installed in the structure and an impeller fan within the duct system. (end of abstract)

Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to toilet fixtures, both domestic and institutional. More particularly, the invention comprises a ventilation system for exhausting related odors from the toilet before they enter the atmosphere of the room. [0003] 2. Description of the Prior Art [0004] Since indoor plumbing was first introduced, efforts have been made to eliminate the associated odors from lingering in the room. Numerous efforts have been made to exhaust these odors directly from the toilet to the outside. [0005] U.S. Pat. No. 6,237,163, to Guzzo, et al.; U.S. Pat. No. 4,898,951, to Rakoz; and U.S. Pat. No. 5,671,484, to Lee, III; all disclose systems wherein air is drawn through apertures in the seat and into a duct system and expelled to the outside or filtered and returned to the interior, while U.S. Pat. No. 5,452,481, to Meyer discloses a system wherein air is drawn into an intake nozzle located between the seat and the bowl rim. In U.S. Pat. No. 4,864,664, to Higgins, a system is disclosed wherein odors are exhausted through the plumbing system, using an air trap. [0006] None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed. SUMMARY OF THE INVENTION [0007] The present invention provides a system for removing objectionable odors from the vicinity of a toilet or urinal by means of an air vent system which may either be built into the toilet or urinal or removably placed on the toilet or urinal. In either system, air is withdrawn through apertures around the inner perimeter of the seat or the bowl by a blower system, through ducts, to the exterior of a building. Optionally, the air could be filtered and/or deodorized and returned to the interior of the building. [0008] In a permanently installed system, air vents would preferably be installed in the interior perimeter of the seat and vented through permanently installed ducts. In a temporary system, an adjustable collar having intake apertures is fitted within the bowl rim and vented through flexible tubing to an exitway, such as a window. [0009] In either system, activation may be by a manual switch in the vicinity of the toilet, by a pressure switch affixed to the seat, or by a motion sensor either in the vicinity of or within the toilet. [0010] Accordingly, it is a principal object of the invention to provide a toilet ventilation system which is inexpensive to produce and install. [0011] It is another object of the invention to provide a toilet ventilation system which is efficient to operate. [0012] It is a further object of the invention to provide a toilet ventilation system which is easy to install. [0013] Still another object of the invention is to provide a toilet system which is unobtrusive in its sizing and routing. [0014] An additional object of the invention is to provide a toilet ventilation system which effectively removes objectionable odors from the toilet, thereby preventing them from entering the interior atmosphere. [0015] It is an object of the invention to provide improved elements and arrangements thereof in an apparatus for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes. [0016] These and other objects of the present invention will become readily apparent upon further review of the following specification and drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0017] Various other objects, features, and attendant advantages of the present invention will become more fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein: [0018] FIG. 1 is a perspective view of the adjustable collar of a first embodiment of a portable toilet ventilation system of the present invention. [0019] FIG. 2 is a perspective view of a toilet with the first embodiment of the portable ventilated toilet system installed. [0020] FIG. 3 is a perspective view of a second embodiment of the portable toilet ventilation system of the present invention with a ventilated seat in lieu of the collar, utilizing ducting external of the toilet. [0021] FIG. 4 is a perspective view of a permanent toilet ventilation system of the present invention using the seat of FIG. 3 and utilizing ducting internal of the toilet. Continue reading...
