Abstract: The present invention is directed to a device that measures volatile organic compounds (VOCs) emitted by an individual's urine, feces or present in flatulence for use in assessing the individual's health. The device may be part of a toilet. The device includes a gas sensor that measures VOCs in the air within the toilet bowl after waste is deposited therein. The device includes a manifold that keeps air from the toilet bowl separate from water and waste in the toilet bowl until the gas sensor has collected readings. Then the manifold combines the air, water, and waste before depositing the material into the sewer system. The gas sensor may be connected to a processor that analyses the gas sensor readings, provides a report of the analyzed data, and transmits the data to a network. A healthcare provider may download the data from the network to assess the individual's health.

Abstract: The present invention's toilet provides a toilet odor removal apparatus The toilet may additionally provide a dual flushing system and/or water overflow prevention system. The odor removal apparatus is operable to withdraw air from a toilet bowl via a suction assembly comprised of a motorized fan to discharge air into a sewer discharge line through a ventilating passage. A valve assembly for controlling the configuration of the system includes a valve controlling means and a solenoid iron plunger. Three main configurations include water flow from the toilet tank to the bowl (flushing), no water flow to the bowl and air flow from the toilet bowl through the fan to the ventilating passage (odor removal), and finally no water flow or air flow (not is use).

Abstract: An odour extraction device (1) for a toilet having a pan (2) and a cistern (4) is disclosed. The extraction device (1) includes an inlet (3) and an outlet (5). The inlet (3) is adapted for gas communication with an interior of the toilet pan (2) above the water level in the pan (2). The outlet (5) is in gas communication with the inlet (3). The outlet (5) is also adapted for gas communication with a sewerage pipe (6). A suction means, in the form of an impeller fan (7), is provided intermediate the inlet (3) and the outlet (5) for drawing gas from within the pan (2) in through the inlet (3) and out through the outlet (5). To prevent backflow of unpleasant odours from the sewerage pipe (6) to the pan (2), a one way valve (8) is provided between the inlet (3) and the outlet (5).

Abstract: The present invention provides a device for detection, collection, containment, neutralization, and elimination of aerosolized contaminants, comprising a lid that fully covers an edge of a container for containment of exiting aerosolized contaminants, with the lid having housing for accommodating an article. The housing comprising a top vent aligned along atop of a bottom vent, with the top vent optionally smaller in size than the bottom vent, and with the housing, the top vent, and the bottom vent located normal to a natural vertical upward move of the aerosolized contaminants. The aerosolized contaminants are detected, collected, contained, neutralized, and eliminated and sanitized by the article within the housing, allowing only uncontaminated air out of the top vent through a natural upward movement of the aerosolized contaminants via the force of the flush.

Abstract: An odourless toilet is provided. The toilet comprises a flush tank comprising a flushing water wet chamber, which comprises a flush assembly; and a flush outlet. The flush tank also comprises a dry chamber, which is positioned adjacent the wet chamber. The dry chamber comprises a chamber inlet, and a ventilator connected to the chamber inlet. The toilet also comprises a toilet bowl, which comprises a basin and, a basin access. The basin access comprises a wet inlet in fluid communication with the wet chamber flush outlet and the basin. The wet inlet serves in conveying the flushing water to the basin. The basin access also comprises a dry outlet in fluid communication with the dry chamber inlet and the basin. The toilet further comprises a diverter, which is positioned between the flush tank and toilet bowl, and registers with the basin access. The diverter comprises a flush passage, which couples the flush outlet to the wet inlet.

Abstract: A venting toilet having a conventional ceramic bowl and flushing tank arrangement includes a water powered odor exhaust system which withdraws gases from the toilet bowl. A suction blower powered by a water motor through which the refill water to the toilet tank flows following flushing is arranged to draw odorous gases from the toilet bowl through a pair of intake manifolds built into the top of the bowl below the seat. The odorous gasses are delivered to the sewer system downstream of the water trap. An energy storage device containing a clock spring wound by the water motor, and a gear box are connected between the water motor and the suction blower, allow operating of the suction blower to draw odors from the toilet bowl even when the toilet has finished refilling.

Abstract: A toilet venting apparatus includes an upper insert mountable between a toilet tank and a toilet bowl, and a lower insert mountable between the bowl and a floor sewer pipe. The upper insert has a first aperture therethrough cooperating between a flush valve aperture in a lower wall of the tank and a water-entry aperture in an upper surface of the bowl. The water-entry aperture cooperates, via a manifold in the bowl, in fluid communication with water dispensing apertures around an upper rim of the bowl.

Abstract: The disclosure herein describes an apparatus for recovering kinetic energy in a free flowing water stream and converting it into useful energy; it comprises a body (22) immerged in a stream, the body defining a duct having an intake side (26) and a discharge side (27). The discharge side is equipped with a deflector (30) which flares outwardly for obstructing the flow of water around the duct to thereby create a negative pressure drag on water being impelled as it is being discharged from the duct. The deflectors flare outwardly at an angle varying from 75.degree. to 160.degree. as measured from the longitudinal axis of the duct.

Abstract: A toilet fan assembly inserted between the water shut-off valve and the toilet intake connector that ventilates the area surrounding the toilet and neutralizes odors through automatic activation of a water-driven fan after the toilet is flushed, the toilet fan assembly requiring no modification to existing toilet fixtures and requiring no electrical power source.

Abstract: Odors associated with the use of toilets are reduced by providing a water driven positive ventilation fan which pumps undesirable odor bearing gases from the toilet bowl and discharges them into the sewer through an auxiliary passage built into the toilet base. Operation of the ventilated toilet is automatic. Water valves coupled to the toilet seat and lid hinges turn on the fan's water turbine when the lid is raised and weight placed on the seat. The fan turbine shuts off automatically when this condition is no longer satisfied. An automatic blocking valve is provided in the auxiliary passage to prevent back-streaming of sewer gas. This gas blocking valve opens automatically when the fan is in operation and closes when the fan shuts off. No electrical connections are required.
