US Patent 11828054 Internally ventilated toilet systems and methods of using the same

A commode has a suctioning exhaust to capture and remove gasses and any other fluids harboring waste. A pressurizing element may maintain around a 0.01-inch water column or more negative pressure airflow into the bowl and out of the vent. The suctioned air can be communicated outside a space having the toilet and waste to prevent any inhabitant or user from interacting with the same. Suction may be taken at any point and at any level, including shutting off or increasing suction at desired times or in response to detected use. A moveable lid and/or seat to the toilet may close the same by rotation and carry a portion of the suctioned exhaust. Systems are useable with existing plumbing and ventilation systems.
