ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a ventilated toilet seat system.
2. Description of the Prior Art
Ventilated toilet seats are known in the prior art. U.S. Pat. No. 4,556,999 to Lindley discloses an apparatus for removing noxious fumes and gases from a commode bowl comprising a toilet seat with circumferentially arranged radially directed inward air passages and a suction pump. U.S. Pat. No. 4,620,329 to Wix discloses a ventilated toilet seat having an internal channel that conveys air through the hinge mechanism of the seat to an exhaust fan. U.S. Pat. No. 5,452,481 to Meyer discloses a portable ventilation system comprising an air duct, a filter and a control unit. U.S. Pat. No. 2,172,506 to Gerger discloses a ventilating attachment to be placed between the bowl and the seat, a motor and a suction device. International Publication WO 90/06404 to Hunnicutt discloses a toilet bowl ventilating system housed within the lid of the seat. A need exists for an improved system that can be manufactured inexpensively, installed easily and maintained easily.
SUMMARY OF THE INVENTION
The invention meeting the needs identified above is a system where air is drawn through holes in a covered groove in the toilet seat and pulled by suction through a channel and hose to an output end of the fan housing. Alternatively, the air may be filtered and recycled or placed in a vent to the outside of the house.
The foregoing and other objects, features and advantages of the invention will be apparent from the following more particular description of a preferred embodiment of the invention, as illustrated in the accompanying drawings wherein like reference numbers represent like parts of the invention.
