Abstract
Abstract The specification discloses an incinerator toilet comprising an incinerator chamber formed by inner and outer walls each of which are formed from a single cylindrical piece of drawn metal and which have their upper and lower ends connected together forming an enclosed and surrounding chamber for holding heat insulation material. An electrical heating coil is removably supported within the chamber with its terminal ends extending outward through the inner and outer walls. A vent line has a first end which extends through the inner and outer walls of the incinerator chamber to the interior thereof and a second end which extends to a position outside of the outer wall. A blower is located outside of the chamber for drawing gases from the interior thereof by way of the vent line. An odor reducing heat activated catalyst is located in a container between the blower and the outer wall of the chamber and in the flow path of gases passing through the vent line. In addition, the vent line is in fluid communication with the enclosed and surrounding chamber in which is located the heat insulation materials.
