Abstract

A store and burn incinerating toilet has a heat permeable upwardly opening receptacle over a combustion chamber and under a deck providing a toilet seat support and having a receiving opening over the receptacle, the opening being closeable by a removable plug closure when a selectively operable heat producing device in the combustion chamber is in operation. Vapor and products of combustion generated in the receptacle pass from the receptacle into the front portion of the combustion chamber and toward the rear of the chamber and into an afterburner flue stack leading from the rear of the chamber. Preheated air is introduced into the receptacle during the burn cycle, and air is also introduced at the lower end of the stack. While incineration is in progress the closure is locked by a thermally responsive safety-locking device. During the accumulating and storing interval, a layer of masking foam may be applied and maintained over the waste in the receptacle.

Dependent claims

A store and burn incinerating toilet, comprising:

a housing;
a heat permeable upwardly opening receptacle of substantial capacity within the housing;
said receptacle being of a size adapting it to receive and accumulate and store waste from a plurality of successive uses of the toilet;
means within the housing defining a combustion chamber in heat transfer relation under said receptacle;
a deck on said housing having a receiving opening over the top of said receptacle and aligned with the upward opening into the receptacle and through which receiving opening waste is adapted to be deposited in said receptacle;
said deck providing a toilet seat support;
a selectively operable heat producing device disposed in said combustion chamber under said receptacle and adapted to heat said receptacle in substantially the manner of heating a cooking pot, but being inoperative while said receiving opening is open to receive waste therethrough for deposit in said receptacle;
a removable closure for said receiving opening to be applied in closing relation to said receiving opening when said heat producing device is to operate;
said heat producing device being operable after the closure has been placed in closing relation to said receiving opening to heat said receptacle and effect substantial boiling and incineration of the stored waste by means of heat permeating from said combustion chamber through at least the bottom of the receptacle from the combustion chamber;
means providing an air passage in preheating relation to said combustion chamber and leading into said receptacle;
an afterburner flue leading from the combustion chamber;
and
means compelling vapor and products of combustion generated in said receptacle to pass into said combustion chamber and to travel toward the flue and thereby causing the vapor and products of combustion to pass through the heat produced by the heat producing device in the combustion chamber.

Apparatus for incinerating toilet waste, comprising:

a heat permeable upwardly opening storage receptacle for receiving and containing waste from a plurality of uses of the toilet;
a combustion chamber under the bottom of said receptacle;
means in said combustion chamber for applying combustion heat directly to and through the bottom of said receptacle substantially in the manner of the application of heat to a cooking pot whereby to effect boiling and combustion of the stored waste;
an insulated enclosure about said receptacle and combustion chamber and having an opening through which waste is adapted to be deposited in said receptacle through its upward opening;
means for closing said enclosure opening during operation of said combustion heat applying means;
an afterburner flue leading from the combustion chamber;
means for supplying preheated air into said receptacle;
and
means compelling vapor and products of combustion generated by said heat in said receptacle to pass into said combustion chamber under said receptacle and through the combustion heat and into said afterburner flue.
