Toilet odor elimination device
A toilet odor elimination device that can be retrofitted to existing toilets and adapted for new toilets includes a toilet intake vent located at the rear of the toilet bowl and which is in flow registration with an odor flow tunnel mounted to the inside front wall of the toilet tank for conveying noxious odors to a filter assembly enclosed within the toilet lid, noxious odors also being conveyed through odor intake vents disposed in odor intake channels extending within the lid, for odor purification and filtering by the filter assembly before release back into the room as freshened and scented air with the filter assembly driven by a fan and motor assembly controlled by a cpu unit, and the actuation of the fan and motor assembly from a program setting button on the toilet lid or from a remote control unit with the running time of the fan and motor assembly being set to various time increments from the program setting button or by time setting buttons on the remote control unit.
The present invention pertains to devices that lessen noxious bathroom and restroom odors, and more particularly pertains to a device that can replace an existing toilet seat for filtering and eliminating noxious odors emanating from the toilet and releasing freshened scented air back into the room.
BACKGROUND OF THE INVENTIONAmong the most unpleasant odors are the unpleasant and noxious odors produced by the use of bathroom and restroom facilities. Such odors can emanate from the use of one's residential bathroom to the continuous use of public restrooms at sports stadiums, airports, bus terminals, amusement parks, shopping malls, etc. It requires a constant effort to at least lessen and diminish such unpleasant and noxious odors by a diligent and active maintenance staff; and thus scrubbing and cleaning regimens as well as the use of fresh scent releasing bars and pads that have been placed within the toilet or adjacent the toilet are employed in the continual effort to diminish such smells and odors. Nonetheless, and in the case of the constant and large scale use of many public restroom facilities, other means, systems, and devices have been employed to arrest and eliminate such unpleasant odors at their source—that is, at the toilet itself. Thus, such systems and devices usually include structure added to or incorporated with the toilet and/or the toilet seat in an attempt to collect or gather as much of the noxious odor emanating therefrom for directing such odors to some type of filtration device or system.
Thus, the prior art discloses a number of systems and devices that attempt to achieve such a goal in an effort to prevent the noxious odors from wafting throughout the bathroom and restroom and permeating other rooms or areas of the house, dwelling, or facility.
For example, the Klemme patent (U.S. Pat. No. 3,416,167) discloses a ventilated toilet seat that includes conduit in registration with a stack pipe and extending through a hinge to the rear of the toilet seat for venting noxious odors from the toilet. A fan placed within the conduit draws the odors from the toilet for discharge up the stack pipe. Toilet ventilation only occurs when the toilet seat is down which thereby aligns the passageways within the toilet seat and the hinge.
The Hunnicutt, Jr. patent (U.S. Pat. No. 5,488,741) discloses a toilet bowl ventilating and deodorizing apparatus that includes an odor collector mounted to the toilet bowl, an air intake and a sleeve in communication with the toilet bowl and the odor collector, and an impeller assembly and a filter assembly for drawing and filtering air from the toilet bowl.
The Sollami patents (U.S. Pat. No. 6,167,576 B1) and U.S. Pat. No. 6,298,500 B1) disclose ventilated toilet seats that include a toilet seat member having at least one hinge receptor for attachment to the toilet bowl, an innermost riser and an outermost riser downwardly projecting from the undersurface of the toilet seat member for forming a seal when brought in contact with the top surface of the toilet bowl, and a plurality of openings spaced about the innermost riser for communicating with a channel located between the innermost and outermost riser for allowing the passage of noxious odors from the toilet bowl and through a conduit extending through the hinge post.
Nonetheless, despite the advantages of the above described prior art, there remains a need for a toilet odor elimination device that is easy to set up and maintain and efficiently dissipates noxious toilet odors and supplants such odors with scented and freshened air that is dispersed throughout the bathroom or restroom.
SUMMARY OF THE INVENTIONThe present invention comprehends a toilet odor elimination device that can be retrofitted to existing toilets or installed in new toilets for eliminating unpleasant and noxious toilet and bathroom odors by filtering such odors and, after appropriate filtering, returning and discharging freshened and scented air back into the room such as a residential bathroom or a public restroom.
The toilet odor elimination device includes a standard toilet having a toilet bowl, a rearwardly extending flange portion and a toilet tank mounted upon the flange portion. The toilet bowl further includes an upper rim, and extending with the flange portion for communication with the upper rim and the toilet bowl is a toilet intake vent. An odor flow tunnel is mounted to the inside front wall of the toilet tank and includes a connector for flow registration with the toilet intake vent so that noxious odors from the toilet bowl are conveyed through the toilet intake vent and up through the odor flow tunnel.
A toilet tank lid is removably mountable to the upper end of the toilet tank for closing off the toilet tank and for registration with the odor flow tunnel so that the noxious odors can be conveyed into and through structural components housed within the tank lid for odor treatment and dissipation and then release back into the room as freshened and scented air. Specifically, the lid includes a lid connector for registration with the odor flow tunnel and a pair odor intake vents with the odor intake vents located on either side of the connector at the front of the toilet tank lid. Centrally located on the upper surface of the toilet tank lid is an openable and closable filter intake and a specially designed filter assembly is removably mountable within an mounting opening on the lid with the closure of the filter intake covering and protecting the filter assembly. Purified, freshened, and scented air is discharged and released back into the room through a fresh air release vent located behind the filter intake. Positioned adjacent the filter assembly is a fan that is driven by a motor with the fan and motor assembly controlled by a cpu unit housed within the toilet tank lid. A manually operable program setting button is mounted on the upper surface of the toilet tank lid and is interconnected to the cpu for allowing the individual to set the run time for the fan and motor assembly, and thus set the odor purification and freshening time. The toilet odor elimination device can also include a remote control unit that provides for additional fan and motor run time options that can range from 10 minutes to one hour.
Thus, upon manually actuating the program setting button on the toilet tank lid, or actuating one of the run time button settings on the remote control unit, the fan and motor assembly are engaged thereby causing noxious odors to be drawn up through the odor flow tunnel and through the odor intake vents for filtering and purification by the filter assembly and freshening by the scented cartridge. The filtered, purified and scented odors are then discharged up through the fresh air release vent for release and dispersal back into the room as freshened and scented air.
It is an objective of the present invention to provide a toilet odor elimination device that eliminates unpleasant and noxious toilet odors at their source thereby preventing the spreading of such odors in the bathroom and throughout other rooms of the dwelling.
It is another objective of the present invention to provide a toilet odor elimination device that is easy to install adjacent the toilet, and is simple to clean and maintain.
It is yet another objective of the present invention to provide a toilet odor elimination device whose parts are manufactured from strong, durable, long lasting plastics such as polyethylene.
It is still yet another objective of the present invention to provide a toilet odor elimination device that can be used in restroom and toilet facilities in office buildings, hotels, motels, bed and breakfasts, hospitals, restaurants, sports arenas, and shopping malls.
It is still yet a further objective of the present invention to provide a toilet odor elimination device that can be used on airplanes, trains, charter buses, RVs, and mobile homes.
Yet another objective of the present invention is to provide a toilet odor elimination device that eliminates and filters noxious odors from the toilet and releases freshened scented air into the bathroom and restroom.
Still yet another objective of the present invention is to provide a toilet odor elimination device that includes structural elements that accommodate and provide for toilet overflow protection thereby preventing damage to the toilet odor elimination device.
Yet still another objective of the present invention is to provide a toilet odor elimination device that eliminates odor by killing odor causing bacteria simultaneous with releasing clean fresh new scented air into the room.
A further objective of the present invention is to provide a toilet odor elimination device that includes a scented filter for releasing freshened scented air back into the bathroom or restroom.
A still further objective of the present invention is to provide a toilet odor elimination device that can be set to evacuate, filter and freshen ambient air for various pre-determined time periods.
