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.

Abstract: An exhaust collector comprising an underside intake secured within the interior of a toilet by a detachable and compressible mounting of the connecting conduit to the sidewall through which it extends to draw discharged odoriferous gases away from the person of the user by means of biased air.

Abstract: An environmentally controlled standard toilet designed to neutralize and confine contaminating agents such as bacteria, odors, vapors and other airborne particles inside the bowl by generating and maintaining a cyclone-type air circulation inside the existing bowl. 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.

Abstract: An environmentally controlled commercial/public toilet designed to neutralize and confine contaminating agents such as bacteria, odors, vapors and other airborne particles inside the bowl by generating and maintaining a cyclone-type air circulation inside the existing bowl. A standard bowl (70a) with a housing (20a), and an air-trapping cavity (76) created inside the bowl (70a) by a detachable bowl-skirt (73a), 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 commercial/public toilets.

A bowl (70) with a housing (20), and an air-trapping cavity (76) created inside the bowl (70) by a bowl-skirt (73), confines the contaminating agents during toilet use and improves the efficiency of the air circulation. Sanitizer and odor conditioner cartridges (31) are employed to neutralize the contaminating agents by releasing sanitizing and odor conditioning agents into the air flow circulated inside the bowl (70). A toilet seat (82) having an ergonomic design has a protective skirt (87) that accommodates a hygienic-shield (100). A solution to body heat loss and noise contamination during toilet use is also addressed. The invention is retrofitable to existing toilets, and is applicable to portable toilet systems including children's training toilets.

Abstract: An automatic air valve for a conduit, through which passes fluids and/or solids, which valve prevents the discharge of contaminated air therefrom into the environment and which further permits the introduction of fresh air from the environment into the conduit when a negative pressure develops therein. The valves may be disposed at either the terminus of or interposed within the conduit flow line of a duct system. The valves include an interior filter that restrains foreign objects, such as insects and snakes, in the duct systems from operatively interfering with the proper operation of the valve.

Abstract: An automatic air valve for a conduit, through which passes fluids and/or solids, which valve utilizes a freely-movable valve member to prevent the discharge of contaminated air therefrom into the environment and to permit the introduction of fresh air from the environment into the conduit when a negative pressure develops therein. The air valves may be disposed at either the terminus of or interposed within the conduit flow line of a duct system. The air valves include an interior filter that restrains foreign objects, such as insects and snakes, in the duct system from operatively interfering with the freely-movable valve member. Means is also included for preventing the interior filter to move or to be moved into a position wherein the interior filter may operatively interfere with the freely-movable valve member. The interior filters are nonplanar in shape, so as to provide a total air passage area that is substantially the same as the air passage area that is present without the interior filter.

Abstract: A toilet ventilation generally comprised of an inventive toilet seat, a pre-filter, a water bleed-off means, an exhaust tubular member, and an electrically powered air extraction means. The inventive toilet seat rests directly on a toilet bowl rim and contains a plurality of ducts within the toilet seat. The series of ducts guide the odorous air toward the air extraction means. A water bleed-off means is implemented to trap moisture suspended in the odorous air and to prevent the moisture from entering the exhaust tubular member and the air extraction means thereby increasing the expected life of the ventilation system.

Abstract: A filtering unit for a bus, the unit comprising one outer housing of a size to fit between the row of seats in the bus and a forwardly facing wall of a bus lavatory behind the seats, the housing having air inlet and air outlet openings for communication with ducts opening in upper and lower portions of the lavatory. The housing comprises a main housing body with an interior horizontal passageway of consistent cross sectional shape extending parallel to the rear of the outer housing, the main housing body having a horizontally facing opening at the outer end thereof which is covered by a panel which is movable to expose said opening, and a drawer unit slidable into or removable from said passageway through said opening. The drawer contains at least an air filter for removing at least lavatory odor-causing gaseous and particle materials from the air stream passing therethrough and an air circulating fan and drive motor therefor.

Abstract: This invention is a sanitary disposal system for human waste and organic garbage by aerobic composting combined with solar evaporative distillation for greywater. The aerobic composting reduces waste volume by ninety percent leaving water, carbon dioxide and a harmless but fertile ash by-product. Except for urine, the system essentially operates dry. No chemicals, septic system, or sewage treatment plant is required. There is no odor and no polluting discharged during operation. A nonsoiling toilet seat is provided so a dry toilet bowl may be used without the usual problems of cleaning. Insects are prevented from entering or leaving the system which is constantly aerated to assure that the composting process does not convert to anaerobic. The greywater system further enhances pollution control. This includes solar evaporative distillation to separate out solids which can be disposed of in a sanitary dump while the reclaimed water can be used for non-household purposes.

Abstract: A portable, toilet ventilating, air-filtering device for boats, house trailers, motels and the like, in which the housing interior is divided into opposite pressure-equalizing plenums by transverse partitioning filter means, and in one of these plenums is mounted a rotatively and vertically adjustable intake duct with spatulate nozzle head that can serve as a carrying handle when nested retracted against the housing top. A suction-blower mounted in communication with the opposed plenum draws air from the toilet bowl and through filter panels for discharge through a bottom opening into a discharge duct recessed in the bottom exterior.
