Composting toilet

An improved composting toilet (1) for composting toilet waste, which toilet comprises a composting chamber (8), in which the toilet waste is received and when needed is mixed with a decomposition-boosting material in order to decompose this compost (3) into humus (2), as well as a container (12), which is located underneath the composting chamber (8) for collection and emptying of the humus (2) progressively forming in the composting chamber, and also a support (16), which is formed with perforations (17) and which is located between the composting chamber (8) and the humus-collection container (12) to support the compost (3) and to allow fall-through of humus (2) from the composting chamber to the humus-collection container, said composting chamber (8) having a lower outlet opening (10) and said support (16) being located in the area of the lower opening (10), a regulating means (21) being positioned between the humus-collection container (12) and the support (16) for regulation of the degree of openness of the perforations (17) in the support and of the passage-through of the humus (2), characterised in that the support (16) is configured as an essentially flat grid (18) having alternating bars (19) and elongate openings (20) forming said perforations (17), said bars and openings extending across the lower outlet opening (10) of said composting chamber (8), and in that the regulating means (21) is configured as an essentially flat sliding damper (22) arranged for sliding lengthwise translatory motion essentially in parallel with the grid (18) and is formed with alternate bars (23) and elongate openings (24), said bars and openings cooperating with the bars (19) and the elongate openings (20) of the grid (18) in order to completely or partly expose and obstruct the grid openings, in order thus to control the decomposition process in the composting chamber (8) by regulation of the moisture balance in the compost (3) contained in the composting chamber.
