SYSTEM FOR VENTING BAD ODORS FROM A TOILET BOWL
The subject matter discloses system for venting bad odors from a toilet bowl comprising an odor suction device integrated with a toilet seat associated with the toilet bowl, adapted to pivotably couple a toilet seat cover to the toilet seat and configured to vent the bad odors emanating from the toilet bowl to a sewage system via a one-way fluid vent system fluidly coupled to said odor suction device. In some cases, the odor suction device comprises a manifold configured to fluidly couple the toilet bowl and said odor suction device and comprising a plurality of fluid flow inlets for venting the bad odors into said odor suction device, and a fluid pump being operative to pump the vented bad odors from said manifold into said one-way fluid vent system.
This invention relates to the venting of bad odors from a toilet bowl.
BACKGROUND OF THE INVENTIONObjectionable odors produced during normal toilet use are a source of concern and embarrassment to many people. Thus, the elimination or diminution thereof has occasioned a great deal of effort and inventive energy.
There are various conventional ways known to reduce the pollution of unpleasant smells, or odors, from a restroom. Such methods include the use of ceiling fans or exhaust fans which typically discharge the unpleasant smell to the outdoors. Further methods include the introduction to the bathroom of a deodorizer to mask the smell.
There is thus an unmet need in the art to provide an efficient system for removing bad odors from the toilet bowl prior to the unpleasant odor spreads to the restroom.
SUMMARY OF THE INVENTIONThe present invention provides a system and method for removing bad odors from a toilet bowl by using an odor suction device associated with the toilet bowl such that a user is able to operate the odor suction device prior to the bad odors dissipating within the restroom.
The system of the present invention includes, inter alia, an odor suction device which is integrally molded, by plastic molding techniques, with a toilet seat associated with the toilet bowl, during manufacture of the toilet seat. The toilet seat cover includes a cutaway portion generating a gap between the toilet seat cover and the odor suction device thereby permitting the seat cover to pivot freely about the odor suction device integrated with the toilet seat.
The present invention also includes a plurality of resilient sealing bungs located on the lower surface of the toilet seat and each bung include a pressure switch for detecting the presence of a user sitting on the toilet seat. On detection of the presence of the user, the odor suction device forwards a commence-operation instruction to a fluid pump to commence the procedure of venting the bad odors from the toilet bowl.
The pressure sensitive switches also provide a safety system such that operation of the system is prevented unless the user positions himself/herself on the seat and the bungs are in contact with the rim of the toilet bowl.
In addition, a safety valve is attached to the toilet seat so as to prevent any physical injury and/or damage to the user if a vacuum is generated within the toilet bowl due to the effect of sealing of anyone of the bungs against the rim of the toilet seat. If the pressure drops in the bowl drops below a predefined value due to the pumping effect of the pump, the safety valve opens so as to equalize the fluid pressure in the toilet bowl to ambient. Additionally, an audio and/or visual warning message is displayed to the user on a user notification unit.
There is provided in accordance with a preferred embodiment of the present invention a system for venting bad odors from a toilet bowl including an odor suction device integrated with a toilet seat associated with the toilet bowl and adapted to pivotably couple a toilet seat cover to the toilet seat. The odor suction device is configured to vent the bad odors emanating from the toilet bowl to a sewage system via a one-way fluid vent system fluidly coupled to the odor suction device.
There is provided in accordance with another preferred embodiment of the present invention a system for venting bad odors from a toilet bowl including an odor suction device adapted to pivotably couple a toilet seat cover and a toilet seat, associated with the toilet bowl and configured to vent the bad odors emanating from the toilet bowl to a sewage system via a one-way fluid vent system fluidly coupled to the odor suction device.
Further in accordance with a preferred embodiment of the present invention, the odor suction device includes a housing enclosing a manifold configured to fluidly couple the toilet bowl and the odor suction device and including a plurality of fluid flow inlets for inputting the bad odors into the odor suction device, and a fluid pump being operatively configured to pump the inputted bad odors from the manifold into the one-way fluid vent system. On operating the pump, a low pressure region is generated in the manifold thereby inputting the bad odors into the manifold and subsequently the pump discharging the inputted bad odors from the manifold into the one-way vent system.
Still further in accordance with a preferred embodiment of the present invention, the toilet seat includes a plurality of resilient sealing bungs located on a lower surface of the toilet seat and each one of the plurality of sealing bungs including a pressure switch, such that a user sitting on the toilet seat, a commence operation signal is forwarded to the pump.
Additionally in accordance with a preferred embodiment of the present invention, the toilet seat comprises a safety valve for ensuring that the fluid pressure in the toilet bowl remains above a predefined value thereby preventing injury to a toilet bowl user.
Further in accordance with a preferred embodiment of the present invention, the housing cover has an inner surface coated with a coating and the housing base has an inner surface coated with the coating. The coating absorbs noise and mechanical vibrations generated during operation of the fluid pump.
Still further in accordance with a preferred embodiment of the present invention, the one-way fluid vent system includes a bad odor filter unit located between the toilet seat and the sewage system for filtering the bad odors flowing through the one-way vent system.
There is provided in accordance with another preferred embodiment of the presnet invention, a system for venting bad odors from a toilet bowl including an odor suction device integrated with a toilet seat associated with the toilet bowl. The odor suction device includes a one-way fluid vent system fluidly coupling the odor suction device to a sewage system. The one-way fluid vent system includes a valve configured to prevent the backflow of the bad odors from the sewage system into the odor suction device and an odor filter unit adapted to filter the bad odors from the bad odor flow flowing through the one-way fluid vent system. In addition, the odor suction device includes a fluid pump being operable to pump the bad odors from the toilet bowl into the one-way fluid vent system. The bad odor flow flowing through the odor filter unit enhances the effectiveness of the odor suction device in removing the bad odors from the toilet bowl.
There is provided in accordance with yet another preferred embodiment of the present invention a system for venting bad odors from a toilet bowl including an odor suction device integrated with a toilet seat associated with the toilet bowl. The odor suction device includes a housing enclosing a manifold associated configured to fluidly couple the toilet bowl and the odor suction device and comprising a plurality of fluid flow inlets for venting the bad odors into the odor suction device and a fluid pump being operative to pump the vented bad odors from said manifold into the one-way fluid vent system and a noise-and-vibration absorbing coating applied to an internal surface of the housing, such that during operation of the pump, the coating absorbs noise and mechanical vibrations to the toilet seat thereby reducing discomfort to the user of the toilet bowl.
