    Abstract: An improved miniature portable child's training toilet comprises a first chamber with a toilet seat opening, a second chamber connected thereto, and a flap member at a connection point. A miniaturized tank portion with valve means and means of selectively causing the valve to open, allows fluid from the tank to move under gravity to the first chamber and continue into the second chamber, flushing material into the second chamber of the toilet. A means of separating the first and second chambers of the toilet for emptying the second chamber after flushing comprises a gasket for sealing the junction of the chambers. An electronic sound and light producing means plays congratulatory sounds and causes the toilet to illuminate when flushed. An alternate embodiment further comprises an “S” bend connecting the chambers, forming a water trap, and causing siphon action when the toilet is flushed.

When the person wants to initiate the flush operation to begin, waving a hand in front of a flush-actuation sensor (34) instructs control unit (26) to start a sequence of actions including locking seat (28) and lid (26) together on the cistern, and simultaneously a delay timer (48) is initiated, set for a delay of 16 seconds being based on a flush duration of 8 seconds for a 4.5 litre flush and (8) further seconds for the miasma, generated by the flush, to subside completely. Accordingly, there is effectively or actually no risk of any contaminated or infected liquid or “miasma” water droplets exiting the cistern.
