  The guiding spiral shaft body 30 is composed of a shaft portion 32 and a spiral blade 33 formed along the outer peripheral axis direction of the shaft portion 32, and the distal end side of the shaft portion 32 is substantially the same as the toilet 4. It arrange | positions so that it may extend below. Thus, the guide spiral shaft 30 is rotated in the arrangement state via the rotation transmission means 31 together with the rotational drive of the discharge spiral shaft body 12. Note that the spiral direction of the spiral blade 33 of the guide spiral shaft body 30 is set so that the spiral blade 33 can be transferred in the lower end side direction of the discharge spiral shaft body 12 in accordance with the rotation operation.

  Then, a substantially semicircular guide guide member 34 is disposed over the entire length of the guide spiral shaft 30 so as to receive the spiral blade 33 of the guide spiral shaft 30 from below, and the guide guide member 34 The lower surface is secured to the bottom surface 2 of the stool container 5 by securing means 35 such as a double-sided tape when assembled. Thus, the guide member 34 is configured to form a transfer guide path from the shaft tip side toward the lower end side of the discharge spiral shaft body 12 by the rotation of the guide spiral shaft body 30.

  In the simple toilet 1 of the present example configured as described above, the stool container 5 is installed on the entire lower side of the floor 3 having a predetermined height from the installation surface by the leg pieces 2 and 2, and the A toilet 4 is attached to the floor 3, and the handle 13 is positioned above the floor 3, and the solid-liquid separation means 10 as a whole facing the inside of the stool container 5 is positioned, and a frame frame 6 is attached to the floor 3. And the frame member 6 is assembled so as to obtain a desired space section as a toilet.

  In this case, the entire solid-liquid separation means 10 is in the stool container 5 and positioned below the toilet 4, and the lower end of the outer cylinder 11 is positioned slightly above the bottom surface of the stool container 5. In addition, a flexible hose 28 in which the discharge pipe 9 in the solid-liquid separation means 10 extends in the lateral (horizontal) direction toward the side wall of the stool container 5 and is connected to the end thereof is provided in the stool container 5. Further, the guide helical shaft 30 and the guide member 34 are extended to the lower side of the toilet container 4 (a portion where excrement (solid matter) is piled up in a mountain shape) on the bottom surface of the toilet container 5. Is to be arranged.

  In the above-described state, it is provided for use as a normal simple toilet 1, and excrement is sequentially deposited in the stool container 5 along with the use, and the accumulated excretion in the stool container 5 The solid matter is separated into a sedimentary layer where solid matter is deposited from below to above, a liquid layer such as human waste, and a floating layer where various suspended matters are located, and the solid-liquid separation means 10 The outer cylinder part is in a state of being buried in the floating layer, the liquid layer, and the precipitation layer.

  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, along with the rotation of the discharge spiral shaft body 12, it is rotated while being received by the guide guide member 34 in the arrangement state via the rotation transmission means 31, and the helical blade 33 is rotated. Accordingly, the rotation guide and the guide member 34 form a transfer guide path in the direction of the lower end of the discharge spiral shaft 12, whereby excrement (solid matter) is formed in a mountain shape substantially below the toilet 4. The part to be deposited can be broken down from the bottom and leveled to the side.

  That is, in the present embodiment, the operation of breaking the excrement (solid matter) accumulated in a mountain shape substantially below the toilet 4 by the rotation operation of the handle 13 and the operation of discharging only liquid such as human waste are simultaneously simplified. And the dislike of the work (operation) can be eliminated as much as possible.

  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.
