An installation table 35 is provided, and the joint 2 portion of the residual water suction tube 31 is configured to open to the bottom surface or lower portion of the residual water suction tube 30. That is, the residual water suction pipe 30 is configured as a unit that can be attached / detached at these joints 32, 33, 34, and can be handled as a single unit, which facilitates maintenance.

(4) Operation Next, the operation of the above configuration will be described step by step with reference to FIG. (1) Closure of Bottom Communication Port 24 by Stored Water First, cleaning water is supplied into the storage unit 23 of the cup unit 2 to store the inside of the storage unit 23 at the bottom communication port 24 at the lower rear end thereof.
To the level where it is blocked. This is done as follows.

By pressing the "start operation" button of the remote controller 10, the pinch valves 41 and 45 are "closed" (the control valves 480 and 490 are "open"), and the first opening / closing valve 63 and the second opening / closing valve 71 are "closed". The vacuum pump 6 is driven in the "open" state. Since the exhaust pressure of the vacuum pump 6 is sent to the wash water tank 7,
The pressure in the wash water tank 7 is increased, and the wash water (warm water) in the wash water tank 7 is increased by the pressure, and the wash water jet nozzle connected to the wash hose 8 (in this embodiment, the wash water jet for women is jetted). It flows out from the nozzle 27). Therefore, the cleaning water jet nozzle 27 functions here as a water supply port for the reservoir 23.

When a predetermined amount of cleaning water is stored in the storage portion 23 of the cup unit 2 and the bottom communication port 24 is closed by this storage water, the second opening / closing valve 71 is closed. Therefore,
By closing the second opening / closing valve 71, the supply of washing water is stopped, and the inside of the washing water tank 7 is pressurized to a predetermined pressure which is slightly higher than before.

(2) Cleaning After excreting, the second opening / closing valve 71 is opened again by pressing the "cleaning start" button on the remote controller 10, and the cleaning water (warm water) in the cleaning water tank 7 is heated by the above predetermined high pressure. ) Is sent to the washing hose 8 and is jetted vigorously from the washing water jet nozzle 27 for women. The sprayed cleaning water is shown in FIG.
As described above, it becomes hot water that spreads flat and fan-shaped in the vertical plane from the upper part of the urethral opening to the lower part of the urethral opening. be able to. Therefore, compared to the type in which the wash water is allowed to flow down from above, the contaminated wash water after washing does not reach the urethral meatus, etc., and therefore Escherichia coli etc. enter the urethral meatus, etc. It is possible to prevent the inconvenience of the onset of the above.

(3) Suction with the dirt hose This is because after the above-mentioned cleaning, the "suction start" button of the remote controller 10 is pressed to suck the dirt with the dirt hose 3 and the remaining residual water suction tube 31. The residual water is sucked. First, as described above, the control valve 48
Both 0 and 490 are in the “open” state, the exhaust pressure of the vacuum pump 6 is drawn into the pinch valves 41 and 45, and both the pinch valves 41 and 45 are in the “closed” state. When the vacuum pump 6 is driven in this state, the degree of vacuum of the tank lower portion 51 is increased via the connecting pipe 61 and the connecting end 57, and through the gap between the tank upper portion 54 and the suction joint pipe 55 and the inner lid 56 in the waste tank 5. .

Next, after the vacuum state is raised, the dirt is sucked. That is, of the control valves 480 and 490, the control valve 480 is changed from the "open" state to the "atmosphere open" state. As a result, the exhaust pressure of the vacuum pump 6 that has been applied to the gap 415 between the outer cylinder and the inner cylinder of the pinch valve 41 up to that time disappears due to the pressure difference between the waste tank 5 side of the pinch valve 41 and the cup unit 2 side. Then, the pressure becomes atmospheric pressure, and the passage of the inner cylinder 412 is opened by the force of the inner cylinder 412 to return to the original O-shaped cross section by the elastic return force. For this reason, the inside of the space up to the bottom communication port 24 of the storage portion 23, which is closed by the filth consisting of wash water and excrement, suddenly becomes the same degree of vacuum as the filth tank 5, and due to this pressure difference, a temporarily large negative pressure is exerted. However, the waste is sucked into the waste tank 5 through the waste hose 3 from the storage portion 23 at once all at once.

Next, the procedure for removing the residual water remaining in the waste hose 3 will be described. First, the control valves 480, 4
Both 90 are in the "open" state, the exhaust pressure of the vacuum pump 6 is drawn into the pinch valves 41, 45, and both the pinch valves 41, 45 are in the "closed" state. In this state, the vacuum pump 6 is driven, and the degree of vacuum of the tank lower portion 51 is increased via the connecting pipe 61 and the connecting end 57 and the gap between the tank upper portion 54 and the suction joint pipe 55 and the inner lid 56 in the waste tank 5. .

Next, after the vacuum state in the waste tank 5 is raised, the control valve 4 of the control valves 480 and 490 is controlled.
90 switches from the "open" state to the "open to the atmosphere" state.
As a result, due to the pressure difference between the waste tank 5 side of the pinch valve 45 and the residual water suction pipe 30 side, and the exhaust pressure of the vacuum pump 6 that has been given to the gap 455 of the pinch valve 45 up to that point disappears to atmospheric pressure. The inner cylinder 452 elastically returns to the original O-shaped cross section, and the passage of the inner cylinder 452 opens. At this time, the joint 2 of the residual water suction tube 31 is opened to the bottom surface or the lower part of the residual water suction tube 30 and is configured to block even the lowest level residual water in the tube by this. The space up to the opening of the residual water suction pipe 30, which is blocked by the residual water, suddenly becomes the same degree of vacuum as the waste tank 5, and due to this pressure difference, the residual water is completely sucked and removed with a large negative pressure. . The residual water suction port portion of the residual water suction pipe 30 shown in FIG. 21 is formed as a slit-shaped suction port 36 to prevent invasion and blockage of the large amount of dirt into the residual water suction tube 31.
