Abstract
An odor control system for capturing odoriferous air from toilet bowls, removing the odor bodies from the air, and returning the cleansed air to the room. A fine water spray nozzle (32) in a duct (30) transfers kinetic energy to the air stream, and also absorbs odor bodies from the air. Energy to generate the water spray and draw air through a ventilated toilet seat is provided by the water under pressure which supplies the usual toilet function. System is started and stopped as needed by the person using the toilet. Supplemental filter (36), e.g. Activated carbon, improves odor cleansing by adsorption. Spray water used is separated from air stream and returned to toilet bowl (20) through check valve (38).
