Abstract
The disclosure relates to toilets of the kind which incorporate a waste-receiving tank or chamber in which decomposition of waste material takes place. In a preferred embodiment of the invention, the toilet includes an air-manifold assembly upon which waste material collects and which receives heated air for removing moisture from the waste material by evaporation, and perforate baffle means which define air spaces laterally of the mass of waste material, into which heated air can pass for improving efficiency of moisture evaporation. A fan unit is provided for circulating heated air through the air manifold assembly and is readily removable from externally of the toilet housing for facilitating servicing of the toilet.
Claims10
A toilet comprising:
- a housing defining a waste material receiving chamber and adapted to allow air to flow through the chamber from an inlet to an exhaust vent, the housing including a top which provides a seating surface and which has an opening for permitting entry of waste material to said chamber;
- means normally closing said opening when the toilet is not being used;
- a perforate waste material support disposed in said waste material receiving chamber above a lower region of said chamber, said support being adapted to allow waste material to pass therethrough into said lower region of the chamber;
- a fan unit mounted in said housing so as to be readily removable from externally thereof, said unit comprising:
- a casing defining a fan compartment having an inlet communicating with said waste material receiving chamber and an outlet;
- a fan disposed in said compartment and adapted to cause air to flow from said inlet to said outlet;
- and means in said compartment for heating air passing from said inlet to said outlet;
- and,
- air conduit means having an inlet engaging and communicating with said fan unit outlet for receiving heated air therefrom, and a plurality of heated air outlets, said air conduit means being arranged to deliver heated air issuing from said heated air outlets in use into the lower region of the waste material receiving chamber for contact with waste material on said support;
- and said air conduit means and fan unit being adapted to co-operate with one another to provide said communication between said inlet of the air conduit means and said fan unit outlet when the fan unit is mounted in said housing, and to permit said fan unit outlet to be readily separated from said inlet of the air conduit means when the fan unit is removed from the housing and wherein said conduit means comprises an air manifold assembly including a header and a neck portion which extends upwardly from said header and which is formed with said air inlet of the air manifold assembly, said inlet being disposed in communicating relationship with said outlet of the fan unit, whereby heated air is delivered directly from the outlet of said fan compartment into the air manifold assembly.
