DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an incinerating toilet, which has a basic structure accommodating a preferably insulating block, which is rotatable in a horizontal plane, and provided with at least one recess in its upper surface, this recess opening out in register with at least one opening capped by a lidded seat ring, in the upper surface of the structure.
The object of the present invention is to provide an incinerating toilet of the kind mentioned above, that fullfils its purpose excellently, while being simple and cheap in production. The distinguishing features of the invention are disclosed in the accompanying claims.
Due to the invention, there has now been provided a toilet, in which waste incineration takes place separately from the place where the user performs his/her natural functions. LPG gas or oil fuel are preferred for combustion, the excess heat generated not being vented directly to atmosphere, but taken into a space between an inner and an outer receptacle, the former being intended for collecting waste and the latter being accommodated in the recess in the rotatable block, effective vaporization of water and/or urine thus being obtained. In previously known solutions this is the most difficult to vaporize and incinerate. Different types of shape and different numbers of receptacles, with or without partition walls, may be used here to afford rapid vaporization of water or urine, by having their bottom areas as large as possible. The capacity of the toilet, i.e. the number of visits it can cope with in a given time, may also be increased by using several receptacles. In addition, effectively improved waste incineration is achieved by supplying air through pipes in a direction towards the waste during combustion, this air causing the solid waste to be broken up, i.e. small cavities are formed in it, enabling the combustion flames not only to contact the solid waste constituents from above, but also such as to penetrate into it, thus providing both complete and rapid incineration thereof. Incineration time is also considerably shortened by combining the just-mentioned air supply with the provision of fins in the space between the receptacles.
The invention will now be described in more detail below, with the aid of a preferred embodiment and with reference to the accompanying drawings, where:
FIG. 1 is a schematic, perspective view, partly in section, of an incinerating toilet in accordance with the invention, which includes a substructure accommodating a block of insulating material provided with recesses, the block being rotatable such that the recesses can come to given stations for use, incineration and possible cooling.
FIG. 2 is a view from above of the block and its recesses, the block being provided with an insulating material.
FIG. 3 is a similar view of the block, without insulation, a scraper blade for removal of paper or other matter also being shown, the blade being adapted for attachment to the central shaft of the block.
FIGS. 4-8 are different views of the inner and outer receptacles and the space therebetween, pipes for air supply to the inner receptacle also being shown in FIGS. 6-8.
FIG. 9 is a view of a lid for use with the receptacles, when one of them is at the combustion station.
FIG. 10 is a similar view to the one in FIG. 1, but shows an alternative embodiment where there are two pairs of inner and outer receptacles, each inner receptacle being rotatable in relation to the block, and provided with at least two compartments, and
FIGS. 11-14 illustrate the receptacle configurations used in the embodiment example illustrated in FIG. 10.
As will be particularly apparent from FIG. 1, the incinerating toilet includes a basic structure 1, which accommodates an insulating block 5, rotatable in a horizontal plane, and provided with at least one recess 2, 2', 2" in its upper surface, this recess opening out in register with an opening 3, capped by a lidded seat ring 4, made in the upper surface of the structure 1.
In each recess 2, 2', 2" there is an inner receptacle 7 wi
