Benefits of technology
"The present invention provides a ventilation system for a toilet that is easy to install and operate, efficient, free from electrical componentry, can be retrofitted into an existing toilet, and is disposed, at least in part, in a toilet. The ventilation system includes a fan that draws odorous air from the toilet bowl and discharges the odorous air from the toilet. The fan is powered by water from a water supply line, and the system is controlled by a water supply valve that is operable upon the application of pressure to the toilet seat. The technical effects of the invention include improved air quality in the toilet, reduced malodors, and improved user experience."
Problems solved by technology
However, ceiling ventilation fans only ventilate unpleasant odors after they have already diffused throughout the restroom facility.
Consequently, ceiling fans are ineffective in eliminating odors before they are generally noticeable throughout the restroom.
Also, ceiling fans are inefficient because they require venting large volumes of air from within the restroom in order to adequately vent the odorous air.
However, such systems are complicated and difficult to assemble.
Further, such systems typically require electrical power to drive a motorized fan.
The components of an electrically powered ventilation system mounted inside a toilet frequently short or fail making the use of electrical powered toilet ventilation systems expensive to supply, maintain, and repair.

Embodiment Construction
[0018] Referring to FIGS. 1 and 2, a ventilation system of the present invention is designated in its entirety the reference numeral 1 and is shown installed on a toilet, generally designated 5. The toilet 5 has a base, generally designated 9, a toilet bowl 13 having a moveable toilet seat 15 for supporting a user of the toilet, and a tank 19 mounted on the toilet bowl for storing water used to flush the toilet. It is understood that the ventilation system 1 of the present invention may be supplied as part of the toilet 5 or as part of a retrofit kit for an existing toilet. The ventilation system 1 is operable to remove odorous air from the toilet bowl 13 prior to detection by a user of the toilet 5.
[0019] A handle 25 mounted on the exterior of the tank 19 is operatively connected to a flush valve 29 located in the bottom of the tank to control the flow of water from the tank to the toilet bowl 13. As shown in FIG. 3, the handle 25 is operatively connected to the flush valve 29 by ...

A ventilation system for a toilet having a toilet bowl, a toilet seat for supporting a user of the toilet, and a tank mounted on the toilet bowl for holding water used in flushing the toilet. The ventilation system includes a fan adapted for connection to the toilet bowl to draw odorous air from the toilet bowl into the fan and to discharge the odorous air from the toilet. A fan water supply line is adapted for fluid communication with the fan wherein water from the water supply line is adapted to power the fan to evacuate the odorous air from the toilet.
Description
BACKGROUND OF THE INVENTION [0001] This invention relates generally to a ventilation system and more particularly to a ventilation system for ventilating unpleasant odors from a toilet. [0002] A variety of ventilation systems are common in the art to dissipate unpleasant odors present in a restroom or lavatory facility. Most commonly, ceiling ventilation fans have been used to continuously withdraw air from the restroom when the toilet is in use. However, ceiling ventilation fans only ventilate unpleasant odors after they have already diffused throughout the restroom facility. Consequently, ceiling fans are ineffective in eliminating odors before they are generally noticeable throughout the restroom. Also, ceiling fans are inefficient because they require venting large volumes of air from within the restroom in order to adequately vent the odorous air. [0003] Ventilation systems have been provided that ventilate air directly from a toilet bowl. However, such systems are complicated ...
