The driving motor 125 is driven to rotate the stirring shaft 123 and the stirring vane 124 coupled thereto. A plurality of stirring vanes 124 are arranged at different angles, and each of the separation scrapers 124a contacts the inner wall surface of the stirring space 121a at different angles and forcibly stirs the feces.

As a result, the opposite sides of the stirring space 121a are uniformly distributed and uniformly distributed over the entire area. The stirring tank heater 127 arranged to surround the stirring space 121a is driven to heat the stirring space 121a and heat is transferred to the feces to evaporate moisture. At this time, the generated odor and methane gas are discharged to the outside through the deodorizing pipe 151 via the activated carbon filter 153 and the blowing fan 155.

When the feces is dried in the reference range of the detection result of the drying completion sensor 140, the controller 170 drives the second door opening / closing means 129a to open the discharge door 129. [ When the discharge door 129 is opened, the manager discharges the dried feces to the outside.

As described above, the faecal treatment tank according to the present invention does not require a separate treatment process such as a microorganism and is easy to manage.

Further, in the treatment tank of the present invention, since the treatment tank heater heats the bathing space, the faeces can be used stably without being frozen even during the winter season.

In addition, since the stirring wing and the separating scraper are provided in different directions in the stool treatment tank according to the present invention, stirring of the feces is improved, and the feces can be dried more quickly. Accordingly, the feces can be dried with a relatively low power.

In addition, methane gas and odor generated during agitation and drying of the feces in the stirring space are forcibly discharged through the deodorizer, so that the toilet can be cleanly used by blocking backflow into the toilet bowl.
