FIG. 11 is a flowchart for explaining the timing of cleaning by the automatic excretion processing apparatus shown in FIG.
First, the case where the excrement is urine will be described with reference to the operation flow chart of FIG.
When the cared person (user) 2 urinates, the urine sensor 23-1 detects urine to turn on (ON) (step S101), and the control device 400 drives the electromagnetic pump 122 intermittently (step S101). S102), purified water flows through the diaper cup 10 for several seconds (for example, spraying for 3 seconds, stopping for 2 seconds × 5 times), and the blower 101 is driven while the electromagnetic pump 122 is driven to clean the water channel 131 and the water purification channel 704. Then, warm water (mixed phase flow) in which air is mixed is caused to flow into the spray nozzles 50a to 50c through the water purification path 303 (step S103), and the warm water is sprayed from the spray nozzles 50a to 50c toward the portion to be cleaned of the user 2. Wash.

By spraying warm water on the urine that is excreted from the nozzle 50, contamination by the user's urine in the diaper cup 10 can be sufficiently washed (step S104).
The excrement disposal apparatus 300 sucks the urine excreted in the diaper cup 10 from the excretion suction port 21 together with the purified water (sewage) that has cleaned the site to be cleaned (step S105). (Step S106).

  After the urine from the user 2 is excreted, the control device 400 supplies hot water from the user wearing device 200 to the diaper cup 10 intermittently for a certain period of time to wash the diaper cup 10 (step S107). The sewage after washing is sucked from the excrement suction port 21 (step S108), and the sewage is discharged to the filth tank 126 provided in the excrement disposal apparatus 300 (step S109). The control device 400 stops the electromagnetic pump 122 and blows warm air from the blower 101 into the diaper cup 10 to dry the portion to be cleaned of the user 2 and the inside of the diaper cup 10. Warm air for drying is blown out from the warm air port 210 in the diaper cup 10 (step S110), and the air used for drying is sucked from the excrement suction port 21 (step S111), and the excrement processing apparatus 300 is filled with air. The bad odor of air is filtered by the provided filter element 105 and circulated between the blower 101, the waste tank 126, and the diaper cup 10 (step S112). When the drying process is completed, the blower 101 is turned off by the control device 400. (OFF) (step S113), the urine processing is terminated.

Next, the case where the excrement is feces will be described with reference to the operation flowchart of FIG.
FIG. 12 is a further flowchart for explaining the timing of cleaning by the automatic excretion processing apparatus shown in FIG.
