  • Patent number: 8691024
    Abstract: A complete sanitary system for any toilet site area which allows for the utilization of pressurized domestic running water transferred through a hose connected to a water valve diverting structure further connected to the main toilet domestic water feed line to that particular toilet's water closet. A floor structure with the aforementioned toilet mounted to its top surface side provides the structure to collect, retain and drain the spent waste water from the hose after the water has been used to cleanse the toilet site area. An alternative drainage location in the retention basin of the floor structure with coinciding plumbing piping method allows for a possible solid waste contamination scenario by an overflow toilet or otherwise to be effectively transferred directly into the main sewer pipe.

    Abstract: Systems and methods for cleaning and monitoring a portable toilet are provided. The system's components include a chemical detector, a concentration sensor, a cleaning device, a container, a rotatable spray nozzle, a locator, an automated door locking device, a processor, and memory. The memory causes the processor to execute a method which involves detecting and sensing urine and feces concentration levels, and cleaning the areas of highest concentration with chemical neutralizers dispersed by the spray nozzle. Data regarding the sanitary condition and GPS location of the toilet may be sent to servers for remote human monitoring. The door locking device may be triggered if the toilet is found to have harmful levels of chemicals associated with urine and fecal matter.

    Abstract: A toilet at least includes a container, a cover, and an inflator. The container includes a top opening and a bottom drain. The cover connects the container with a pivot for selectively shielding or exposing the top opening. When the cover shields the opening, the inflator supplies air into the container and makes the air pressure inside the container higher than the outside. And therefore, air flows and takes away wastes through the drain to the outside of the toilet due to the pressure differential.

  • Patent number: 4797959
    Abstract: The invention relates to a sanitary unit having an automatic cleansing cycle. The unit comprises a lockable enclosure in which a partition defines a usage zone and a maintenance zone. A bowl is mounted for rotation between a utilization position in which it projects horizontally from the partition in said usage zone and a cleaning position in which it is tipped up into an opening in the partition so as to empty it into the maintenance zone. The upwards opening of the bowl is separated into two sections by a partition wall which extends upwardly to cooperate with the front walls of the bowl to form a rim surrounding the utilization section of the bowl. The bottom of the partition wall stops short of the base of the bowl to define an orifice and the rear section of the bowl forms an evacuation passage from the evacuation orifice rearwards to the maintenance zone when the bowl is tipped up.
