Abstract
The invention provides a portable apparatus having housing structure with a duck-bill shaped gas inlet that is fitted between the top face of a toilet bowl and the underside of the lowered toilet seat, to open directly to air confined within the bowl. Remaining housing structure defines an air flow path to a gas outlet outside of the toilet bowl. A blower and an electric heater in the housing structure air flow operate for withdrawing and then heating the toilet bowl gases before discharging such gases from the outlet back to the ambient air. By heating the gases to temperatures between 450-1000 degrees F., in sufficient volumes to provide between 5-100 turnover of the confined bowl gases per minute, and discharging the treated gases at temperatures in the range of between 150-400 degrees F. back to the ambient air, most defecation odors are eliminated or minimized.
