In the combustion device 11, a shaft 14 that is rotated by a motor 13 that is turned on and off by a signal from the control device 6 is inserted into a cover 12 (which can also serve as the base 1) made of a noncombustible material. A drum 16 is mounted on a roller 15 fixed to a shaft 14, and the rotation of the roller 15 causes the drum 16 to slowly rotate around a horizontal axis.

A distal end of a transfer pipe 18 for feeding waste from the toilet bowl 5 into the drum 16 penetrates through the cover 12 at an opening 17 formed at one end of the drum 16. A flame ejection pipe 20 of a burner 19 which is turned on / off by a signal from the control device 6 faces to 17. The burner 19 is supplied with fuel (oil) from a fuel tank 22 by a pump 21.

Here, by bringing the tip of the flame discharge pipe 20 of the burner close to the tip of the transfer pipe 18, the contaminants in the transfer pipe 18 are forcibly removed by the drum 1 due to the negative pressure at the time of the flame discharge.
6 can be withdrawn.

A stirrer 23 that rolls with the rotation of the drum 16 is placed in the drum 16.
Has a small diameter portion 16a, which is inserted into a duct 24 which is integrally or separately connected to the cover 12, and the other end of which is connected to the collecting portion 2a.

By adjusting the weight of the lower valve 35, the lower valve 35 can be rotated downward after the human waste has accumulated on the lower valve 35 several times.

In order to store human waste several times in the case 31, it is necessary to keep the lower valve 35 closed when the upper valve 34 is open. For this purpose, in this embodiment, a spring 42 is stretched between the balance weight 38 and the lower valve 35.

In the above, the dirt thrown into the rotating drum 16 is burned by the flame from the flame discharge pipe 20 of the burner 19, and the ash generated by the combustion passes through the duct 24 and is collected under the collecting section 25. The combustion gas collected in the box 26 is discharged outside through the deodorizing device 28. At this time, fly ash mixed with the combustion gas is removed by the solid-gas separation device 29. Since the ash generated by combustion is extremely small, it is sufficient to take it out regularly.

Here, in the present embodiment, the treatment of the odor is taken into consideration both in the pre-purge of the burner 19 and in the combustion. That is, since the temperature is low at the time of pre-purge, the malodor generated is the odor of the waste itself, mainly ammonia. Thus, an inorganic chemical is introduced into the drum 16 to adsorb ammonia, and the adsorbed ammonia is released when the temperature in the drum becomes high. On the other hand, when the combustion proceeds, the temperature becomes high. Is a mixture of ammonia and sulfur-based malodorous components. Therefore, the combustion gas is treated (decomposed) by passing it through an oxidation catalyst filled in the deodorization device 28.

The waste is incinerated as described above. Whether or not the waste is completed is determined by a temperature sensor or an infrared sensor 42 disposed in the cover 12.
