  • Patent number: 11149425
    Abstract: Please amend the abstract as follows: This invention relates to a ventilated toilet system for removing obnoxious odors from the toilet base and includes integral vent channels formed along the base and the back inside of the water tank, and a vent adapter mounted inside the passage that directs the flow of ventilating air along the vent channels to an exhaust pipe and discharges it by a remote in-line exhaust fan to the outside atmosphere. The adapter is attached to the base of the overflow flush valve pipe or, conversely, designed to be an integral part of the overflow flush value pipe, itself, and is positioned to connect the base vent channel of the water tank to the toilet water inlet chamber of the base for passage of ventilating air, and to connect the overflow flush valve pipe to the water inlet chamber for passage of flush water.

    Abstract: A ventilation system for a toilet which functions by drawing air from around the bowl through the original flush holes into the existing overflow-pipe and then into a fan compartment. The fan is activated by manipulating the flush handle upward. Malodorous air is then forced through an exhaust pipe into the sewage line downstream of the gas trap. The fan is deactivated when the flush handle is pressed downward and the toilet is flushed. A water-trap between the fan and the toilet tank prevents the malodorous air from escaping into the tank. The water in the water trap is changed with each flush by redirecting the refill tube into the water trap. This prevents the water in the water trap from becoming stagnant.

A standard toilet bowl (70a) with a housing (20a), and an air-trapping cavity (88b) created inside the bowl (70a), by a seat (82b) having a seat-skirt (87b), confines the contaminating agents during toilet use and improves the efficiency of the air circulation. Sanitizer and odor conditioner cartridges are employed to neutralize the contaminating agents by releasing sanitizing and odor conditioning agents into the air flow circulated inside the bowl (70a). This invention is retrofitable to existing standard toilet bowls.

  • Patent number: 5255395
    Abstract: The invention consists of a ventilating system and particularly a ventilating kit to be installed on a conventional toilet bowl at the rear of the toilet seat above the apertures used to anchor the toilet seat to the toilet bowl. The kit includes a parapet-like housing having a peripheral wall member adapted to be mounted over and in contact with the back apron of the toilet bowl and disposed to encircle both apertures vertically extending therethrough. A pair of hollow T-shaped couplings are adapted to be mounted below each of the apertures for providing an air passageway from the housing through the apertures and into a piping arrangement which projects into an adjacent wall of the toilet room wherein a suction device is located. A cover is fittingly mounted over the parapet-like housing and has a pending lip facing the seat cover and adjacent thereto for defining an air passageway extending between the rear of the bowl and inside the housing.

  • Patent number: 5231705
    Abstract: A system for removing unpleasant gaseous odors in a toilet having a bowl, a tank, and an overflow tube is disclosed. The system includes an air intake port located in the toilet bowl. A battery powered suction pump assembly contained in the tank is connected to the air intake port by a suction tubing. A charcoal filter is connected to the suction pump assembly. The suction pump assembly passes the odoriferous air through the charcoal filter prior to exhausting the filtered air into an exhaust tubing which releases the filtered air into the overflow tube. Also disclosed is a method of deodorizing gaseous odors and recirculating the deodorized air in a toilet having a bowl, a tank, and an overflow tube. Odoriferous air is sucked in and removed from the toilet bowl and then filtered and deodorized. The filtered and deodorized air is released into the overflow tube in the tank.

  • Patent number: 5161262
    Abstract: An apparatus for removing odors from toilets represents a new level of sophistication, adaptability, convenience, aesthetics and performance. The apparatus includes an adjustable housing having first and second sections, both with neck portions, one of which telescopes into the other to conveniently mount upon and adjust to various toilet sizes. Each section defines a wide, thin air inlet which is disposed adjacent the toilet bowl rim and which communicates with the hollow interior of the housing sections. In one section of the housing is a battery pack, timer circuit and on-off switches. In the other section is an activated charcoal filter and fan or blower which draws foul air from both air inlets, removes odors by drawing it over the charcoal filter and returning it to the ambient. The telescoping neck portions include a pair of sliding electric contacts which provide electricity to the fan motor from the battery pack and timer circuit.

  • Patent number: 5136729
    Abstract: An odor removing device for toilets includes an odor collector secured to the conventional hinge posts of a toliet bowl. The odor collector has a single inlet opening and is connected in communicating relation to a downwardly convex auxiliary venturi housing which overlays the conventional bathroom ceiling fan. An air stream is introduced centrally into the auxiliary venturi and produces a venturi effect to thereby cause rapid evacuation of the noxious gases, steam and the like.

  • Patent number: 5029346
    Abstract: A system for venting odors from a toilet having a bowl with a plurality of openings disposed about its rim and a tank to store water with a bowl fill tube interconnected with the openings. A vent is positioned above the level of maximum water storage in the tank. A low pressure region within the vent is established bias air flow through bowl rim openings in the toilet and also through a bowl fill tube in the toilet tank and into the vent. Finally, an exhaust outlet is located at a remote point from the toilet in order to output the air flow from the toilet. To improve venting of air flow between the vent and the fill tube, the tank lid may include a seal positioned between the lid and the tank. The system may also include a valve with dampers that allow air flow to enter the tank during flushing and allow air flow to exit the tank during venting, but that limits air flow when the system is inoperative.

  • Patent number: 4800596
    Abstract: A toilet has a toilet bowl and a flushing tank which accommodates a supply of flushing liquid for the bowl. The bowl, which discharges into a waste line, is connected to the flushing tank by a flushing pipe. A second pipe for evacuating odors from the bowl likewise leads from the bowl to the tank. This evacuating pipe has an open end in the bottom of the bowl and a second end in the tank. An air duct hooked into the waste line also extends into the tank and can be caused to communicate with the evacuating pipe when the toilet is in use. The air duct is provided with a blower which functions to convey odors from the bowl to the waste line via the evacuating pipe, flushing tank and air duct. A liquid seal cuts off communication between the air duct and evacuating pipe when the toilet is not in use to prevent backflow of odors from the waste line to the bowl. The liquid seal is located in the flushing tank and is established using the flushing liquid accommodated by the same.

  • Patent number: 4200940
    Abstract: The invention describes a system for removing the odors associated with the bodily discharge of odorous volatile gases associated with the use by the human body of the toilet stool. A hollow toilet seat having radial holes associated with the centermost portion is supported and communicates with a vacuum device for drawing air from the hollow portion through the radial holes through the ported toilet seat and through this vacuum device. An incinerating device such as a grid of tungsten wires or a glow plug is inserted in the passageway and connected to an electrical source, preferably one of low voltage, for incinerating and burning the odorous volatile body gases. The discharged by-products of combustion may either be discharged into the room or may be discharged through suitable wall fittings to the outside atmosphere. Incinerating the odorous volatile body gases destroys the odor allowing the by-products of combustion to be discharged back into the same bathroom atmosphere.
