First, the switching valve 22 is set in the opening direction to activate the vacuum pump 7, and then the suction port 2 of the suction body 1 is brought into close contact with the anus portion as shown in FIG. When the suction port 2 is blocked in this way, the negative pressure inside the negative pressure chamber 2 becomes negative due to the operation of the vacuum pump 7. Therefore, the cleaning water W in the water supply passage 9 provided so as to surround the inside of the suction port 2 Is sucked, and thus the washing water W is jetted from the jet hole 11 to wash the area around the anus, while the air around the suction port 2 is sucked into the negative pressure chamber 2 through the air passage 12. The air and excrement are sucked into the chamber 6 through the discharge hole 4 and the suction hose 5 together with the cleaning water W. In this case, the valve body 17 attached to the bottom of the chamber 6 is closed by the suction force of the vacuum pump 7, and the sucked excrement and the wash water W remain in the chamber 6. Next, when only the switching valve 22 is switched to the closing direction while the vacuum pump 7 is operating at the stage when the cleaning is completed, the supply of the cleaning water W is stopped and only the air sucked through the ventilation passage 12 is stored in the chamber. The residual washing water W that has been sucked into 6 is drained, and the anus portion wet with the washing water W is dried by the flow of air. After the drying, when the vacuum pump 7 is stopped, the valve body 17 of the chamber 6
The excrement remaining in the chamber 6 and the wash water W are opened.
Are dropped into the waste tank 8 and are appropriately discarded.

As described above, in the present embodiment, the vacuum pump 7 absorbs the excrement, and the suction force thereof causes the washing water W to be ejected to wash the area around the anus to effectively remove dirt. The cleaning water W automatically stops when the vacuum pump 7 is stopped.
There is no need to worry about wetting the futon with the wash water W, and by switching the switching valve 22 to forcibly stop the wash water W, the removal of excrement and the simultaneous drying of excrement can be performed. You can In addition, it is possible to hygienically remove the dirt without the physiological discomfort of wiping it by relying on human hands.
