Abstract
Abstract The specification discloses an incinerator toilet having a seat mounted on a heat insulated bowl with an upper tapered baffle in the bowl extending down to a lower tapered baffle. A fuel nozzle from a fuel pump injects fuel chordally into the space between the lower baffle and the bowl past a spark plug, which ignites the fuel, air being blown in with the fuel by a lower blower having an outlet coaxial with the nozzle. A second blower blows air into an annular passage at the upper end of the bowl, and this air travels into and down the upper baffle. The air and the products of combustion are exhausted through an exit port through the bowl positioned above the lower baffle. When a cover is placed in the opening to close a limit switch and a push button is held closed, an igniter circuit, the fuel pump motor and the lower blower are energized. If flame is present, the circuit is locked in by a timer and the upper blower is energized. After an incineration period expires, the timer drops out the fuel pump motor and the igniter, and increases the speed of the lower blower during a cooling cycle. Then, when the chamber temperature is lowered to a desired point, a temperature sensor drops out the upper blower and resets the circuit.
