  Liquid such as human urine in the liquid layer sequentially flows into the outer cylinder 11 from the inflow hole 17 below the outer cylinder 11, and when the water level reaches the communication site with the discharge pipe 9, the discharge pipe 9 and the flexible hose 28 to be discharged to the outside of the stool container 5.

  At this time, in a state where the water level of the liquid layer in the stool container 5 is higher than the overflow inflow hole 18 of the outer cylinder 11, the liquid such as human waste in the liquid layer is overflowed in the overflow inflow hole in the outer cylinder 11. 18 is sequentially introduced into the outer cylindrical body 11 and discharged to the outside of the stool container 5 through the discharge pipe 9 and the flexible hose 28 in the same manner as described above.

  Then, when the user uses the simple toilet 1, the handle 13 bulging from the floor 3 is rotated in one direction (rotation direction in which the spiral blade 20 of the discharge spiral shaft 12 moves upward), Since the discharge spiral shaft body 12 connected to the handle 13 is integrally rotated, and the spiral blade 20 is rotated in the direction in which the spiral blade 20 is moved upward along with the discharge spiral shaft body 12, the liquid in the outer cylinder body 11 The rotation of the spiral blade 20 guides the transfer in the upward direction and positively flows out (discharges) to the communicating portion with the discharge pipe 9.

  In this case, since the clogging prevention rotor blade 27 is rotated along with the discharge spiral shaft body 12 along the outer periphery of the outer cylinder body 11 facing the inflow hole 17, the inflow hole 17 is rotated by the rotating rotor blade 27. It is possible to prevent the inflow of solid matter in the sediment layer that is about to flow into the inflow hole, to prevent clogging in the inflow hole 17 and to smoothly inflow the liquid from the inflow hole 17. As a result, only liquid such as human waste in the stool container 5 can be reliably discharged.

  Filter members 25 a, 25 b, 25 c, 25 d are provided at the inflow holes 17, 17 through which the liquid flows in the outer cylinder 11, the upper overflow inflow holes 18, and the discharge pipe 9 and the outer cylinder 11. Furthermore, since the lower mesh filter member 26 is provided in the vicinity of the lower end opening of the outer cylinder 11, the inflow of floating substances and solid substances flowing into the outer cylinder 11 together with the liquid is prevented. Thus, the flow of the liquid in the outer cylindrical body 11 can be made smooth, and only the liquid such as human waste can be discharged to the outside.

  Further, the liquid discharged from the discharge pipe 9 is passed through the sterilizing agent cassette member 29 containing the sterilizing agent provided in the discharge pipe 9 to be discharged to the outside of the stool container 5 through the discharge pipe 9 and the flexible hose 28. The problem of sanitary liquids can be solved.

  In the present embodiment, the outer cylindrical body 11 is configured such that the connecting portion between the shaft portion 19 of the discharge spiral shaft body 12 and the handle 13 can be connected and folded via the connecting pin 22 so as to be able to transmit rotation. In addition, the discharge spiral shaft body 12 can be folded (rotated) in a substantially horizontal state along the lower surface of the floor 3, and the handle 13 can be folded (rotated) in a substantially horizontal state along the upper surface of the floor 3. 1. The entire packaging, transportation, storage, etc. can be handled easily and easily.
