  • Patent number: 6367092
    Abstract: A capacitance charge transfer sensing and control system for a venting system. Preferably the sensing and control system is used with a toilet having an integrated venting system which includes ducting communicating with an exhaust air passageway located in the toilet bowl and an exhaust fan to draw air from the bowl and exhaust it outside. A sensing electrode, such as a wire antenna, is located in a covered location adjacent the toilet bowl, preferably in the exhaust air passageway located in the bowl of an integrated toilet venting system. The wire antenna is connected to a detection and motor control circuit which can detect a change in capacitance of the wire antenna upon a person entering into close proximity thereto. A micro-controller in the detection and motor control circuit is programmed to generate a circuit closing signal to an electric switch located in the circuit between a power source and the exhaust fan in response to a minimum pre-selected increase in the capacitance of the wire antenna.

The air evacuation system may be associated with a dedicated vacuum-creating pump or be integral with a ceiling exhaust fan which has the capability of either exhausting air from the bathroom or through the toilet bowl air evacuation system.

  • Patent number: 5896591
    Abstract: An air treatment device for conditioning air within a conventional toilet bowl includes an air treatment assembly and an automatic flush mechanism. The air treatment assembly includes a cylindrical housing mounted to the rear of the toilet bowl rim with the toilet seat and lid swingably mounted thereto and an air duct having a free end extending into the toilet bowl proper. A seal underlying the toilet seat contacts the toilet bowl rim when the seat is in a horizontal position. Included within the housing are fans which draw air through the duct and a carbon filter to treat the air drawn therethrough. A flush assembly includes a motorized arm having a free end attached to the conventional flapper found in the water tank of the toilet bowl. Upon powering the motor, the arm moves the linked flapper valve from its normal closure position which allows the water to escape from the tank and flush the toilet bowl.

  • Patent number: 5850638
    Abstract: A toilet ventilator system is provided including a ventilation housing having a C-shaped configuration defined by a top face, a bottom face, an inner side face, and an outer side face defining a constant square vertical cross-section along an entire length thereof. The top face of the housing is secured to the lower surface of the toilet seat with pair of closed spaced ends of the housing spaced from a center of a front portion of the toilet seat by an equal distance. The inner side face of the housing has a plurality of ventilation ports formed therein and spaced along a length thereof. Each port has a plurality of grouped apertures in communication with the interior space of the housing. A vacuum assembly is adapted to effect the suction of air from the inlet to the outlet upon actuation, whereby suctioned air passes through a scented filter situated within the vacuum assembly prior to exiting.

  • Patent number: 5839127
    Abstract: An improvement for toilet assemblies wherein an odor extractor device is connected to the overflow tube of the toilet assembly. The water supplied through a conduit to the overflow tube is discharged on a tubular member that is connected to an opening on the lateral wall of the overflow tube. A flexible sheet is mounted over the opening, on the internal surface of the lateral wall of the lateral wall of the overflow tube. The flexible sheet maximizes the suction applied to the bowl rather than the tubular member so that the gases typically associated with these excretory functions are extracted through the conventional drain apertures found in bowls.

  • Patent number: 5806104
    Abstract: A bathroom deodorizing device for use with a conventional toilet bowl includes a housing having an inlet located between the rear of the toilet seat and the toilet bowl. The inlet captures offensive air which is drawn into the housing by a fan and into a deodorizing chamber. The chamber is in fluid communication with a first and second chamber. The first chamber contains a liquid deodorizer and the second may also contain a liquid deodorant and/or a liquid which is used to impart a desired fragrance into the air before it exits the device. As the air is bubbled into the liquid deodorizer contained in the first deodorizing chamber, the air is cleansed, purified and deodorized and enters the second chamber for a second process and is then released into the surrounding environment. The device includes a pressure activated switch to turn the device on.
