Abstract
Abstract An electrical combustion toilet including a housing having a seat and a cover, a first receiving chamber for receiving toilet wastes, a combustion chamber situated below the first receiving chamber adapted to receive wastes therefrom by force of gravity and to electrically incinerate the wastes, an ash chamber for receiving combustion residue from the combustion chamber, and a fireproof cover adapted to seal the combustion chamber. The toilet is rendered firedamp-proof by an encapsulation structure and by being supplied with pressurized air for preventing explosive gas mixtures.

An electrical combustion toilet comprising a housing having a seat and a cover for said seat, a first receiving chamber for receiving therein toilet wastes, a combustion chamber situated below said first receiving chamber adapted to receive wastes from said first receiving chamber by force of gravity and to electrically incinerate said wastes, an ash chamber for receiving combustion residue from said combustion chamber, a fireproof cover adapted to seal said combustion chamber, encapsulation means enclosing said combustion chamber and said ash chamber supplied with pressurized air for rendering said toilet firedamp-proof, said combustion chamber and said ash chamber being constructed in such a way as to be permeable by pressurized air by means of a pressurized air inlet line and a pressurized air outlet line, said pressurized air inlet line feeding an approximately circular flushing tube having pressurized air outflow openings for flushing air arranged in said combustion chamber, said toilet further comprising switching means for starting activation of said electrical combustion toilet and for starting flow of pressurized air therein, means for effecting limited-time flushing of said combustion chamber and of said ash chamber by means of said pressurized air through said circular flushing tube, means for opening said combustion chamber cover and for simultaneously effecting dropping of waste matter into said combustion chamber with subsequent closing of said cover, means for effecting renewed time-limited pressurized air flushing, means for switching on activation of heating elements in said combustion chamber and for time-limited activation of said heating elements under slight excess pressure by maintaining a passage of flushing air, means for switching off said heating elements, means for time-limited after-flushing by means of pressurized air, means for time-limited blowing-out of ash from said ash chamber by means of pressurized air and means for switching off said pressurized air.
