PURPOSE:To prevent the incapability of rotation of a cutter section and make it possible to beat foreign matters by turning a cutter blade backward for a while, when foreign matters, which are not easy to be cut by the cutter blade, flow from a human waste inflow port and the shock when they are cut is applied to the cutter blade. CONSTITUTION:The human waste poured from a flush toilet stool together with carrier water in a low tank flows inside a screen 6 through a human waste inflow port 2. The carrier water flow down to a reservoir bottom section through the meshes of the screen 6 raising the water level in a reservoir 1. When the water level is raised higher than the level set by a water level detection switch 3, a submerged pump 4 is operated to forcingly discharge the carrier water. At the same time, the human waste and toilet paper inside the screen 6 are broken by the cutter inside the screen 6. In this case, when foreign matters other than human waste such as absorbent cotton, cloth, etc. flow inside the screen 6, cutter blade 11 is turned backward opposing to the energizing force of a spring 12. This constitution prevents the binding of a cutter section 10, the foreign matters are cut little by little and are discharged. |
