Abstract An electric toilet of the kind which presents a vertical shaft which, by means of a heat-insulating plate or the like capable of being inserted between both chambers can be divided into a lower compartment, the combustion chamber, containing an electric heat source and a grid, and into an upper compartment, the seat cone compartment housing a seat cone extending downwardly below the toilet seat, the bottom and sidewalls of the combustion compartment being heat insulated by a suitable insulating material and the combustion compartment or chamber communicating with an upright exhaust gas flue and further presenting a removable ash box, in which the external insulation of the combustion chamber of the electric toilet is at least partly shielded by columns of air which, for the purpose of creating conditions for a sufficiently good cooling of exposed parts by natural draught and for preheating air supplied to the combustion chamber, communicate freely at their bottom ends with the ambient air and open at their top ends into the seat cone compartment and via the latter, in the operative position of the plate, communicate with the combustion chamber through apertures, spaces or the like having a limited flow area as compared with said flue and preferably arranged either in the plate or in the wall of the combustion chamber or formed between the plate and the latter.
An electric toilet of the kind which presents a vertical shaft which is divided into a lower combustion chamber containing an electric source of heat and a grid and an upper seat cone chamber which accommodates a seat cone extending downwardly below the toilet seat, said chambers being separated by a heatinsulating plate capable of being inserted and withdrawn therebetween, the bottom and the sidewalls of the combustion chamber being heat-insulated by means of suitable insulating material positioned adjacent the inside surface of the walls and said combustion chamber communicating with an upstanding smokestack, the improvement comprising the shaft having a vertical air column arranged between the combustion chaMber insulating material and the inside surface of the walls communicating freely at the bottom thereof with the ambient air and at the top thereof with the seat cone chamber, the shaft having an air passageway formed between the plate and the inside surface of the insulating material so that the seat cone chamber in turn communicates with the combustion chamber and a second plate spacedly secured to the heat-insulating plate forming a horizontal column of air beneath the bottom of the seat cone and communicating with the vertical air column and the combustion chamber wherein air is drawn into and through the shaft without being heated prior to entering the combustion chamber in the absence of powered forced airflow.

An electric toilet of the kind which presents a vertical shaft which is divided into a lower combustion chamber containing an electric source of heat and a grid and an upper seat cone chamber which accommodates a seat cone extending downwardly below the toilet seat, said chambers being separated by a heatinsulating plate capable of being inserted and withdrawn therebetween, the bottom and the sidewalls of the combustion chamber being heat-insulated by means of suitable insulating material positioned adjacent the inside surface of the walls and said combustion chamber communicating with an upstanding smokestack, the improvement comprising the shaft having a vertical air column arranged between the combustion chaMber insulating material and the inside surface of the walls communicating freely at the bottom thereof with the ambient air and at the top thereof with the seat cone chamber, the shaft having an air passageway formed between the plate and the inside surface of the insulating material so that the seat cone chamber in turn communicates with the combustion chamber and a second plate spacedly secured to the heat-insulating plate forming a horizontal column of air beneath the bottom of the seat cone and communicating with the vertical air column and the combustion chamber wherein air is drawn into and through the shaft without being heated prior to entering the combustion chamber in the absence of powered forced airflow.
Claim 3
Dependent Claim
52 words
An electric toilet according to claim 1, wherein the shaft has a gap between said second plate and the seat cone which permits said second plate and said heat-insulating plate to be withdrawn and inserted and which provides for air communication between the interior of the seat cone and the combustion chamber.
Claim 4
Dependent Claim
23 words
An electric toilet according to claim 1 wherein the shaft has means fluidly communicating between the seat cone chamber and the ambient air.
