The injection timing of the injection nozzles 211-a to 211-b and 212-1 to 212-3 of the diaper cup used is shown.

  The automatic excretion processing apparatus 300 injects from the injection nozzles 213 and 214 of the diaper cup in principle at a predetermined time (for example, 10 minutes) every predetermined time (for example, 10 seconds). (Periodic cleaning), and when the user 1 excretes (defecate), the ejection nozzles 211-a to 211-b and 212-1 to 212-3 together with the ejection nozzles 213 and 214 for a certain period of time (defecation diaper cup 201 It is characterized in that spraying (temporary cleaning) is performed for a time required for extruding and cleaning, for example, 30 seconds. This is to use purified water efficiently.

  For example, as shown in FIGS. 20A and 20B, when a power switch (not shown) of the automatic excretion processing device 300 is turned on at 7:00 in the morning, the operation starts, and the control device 400 (FIG. 18) Then, it is determined whether t1 has elapsed after the electromagnetic pump 122-1 (FIG. 18) is stopped. In this embodiment, when the power switch is turned on, the electromagnetic pump 122-1 is activated and purified water is supplied from the purified water tank 121, and purified water is supplied from the injection nozzles 213 and 214 for a predetermined time t1 (10 seconds: FIG. 20 (a)). Shall be sprayed. Further, it is assumed that there is a sufficient amount of the purified water 120 in the purified water tank 121, and the temperature has already reached an appropriate temperature by the heater 123 (step S1: FIG. 19).

  When t1 has elapsed after stopping the electromagnetic pump 122-1 (step S1 / Yes), the blower 101 starts to be driven by an instruction from the control device 400 (FIG. 18). When the blower 101 starts driving, the fan 102 rotates, the tube 113 side becomes positive pressure, and the tube 110 side becomes negative pressure. For this reason, the air in the diaper cup 201 is sucked into the fan 102 via the excrement guide channel 215, the connectors 226 and 803, the hose 708, the air channel 112, the filth tank 126, the centrifuge mechanism 129, and the tube 113. .

When the electromagnetic pump 122-2 is being driven (step S8 / Yes), since the user 1 is excreting (during defecation), the control unit 400 (FIG. 18) continues to drive the electromagnetic pump 122-1. This is for cleaning the inside of the diaper cup 201. (Step S9: FIG. 19)
The control unit 400 (FIG. 18) determines whether t3 has elapsed after the electromagnetic pump 122-2 is driven (step S10: FIG. 19), and when t3 has elapsed (step S10 / Yes: FIG. 19), the electromagnetic wave The pump 122-2 is stopped (step S11: FIG. 19), and the electromagnetic pump 122-1 is stopped (step S12: FIG. 19).

  The control unit 400 (FIG. 18) is necessary for the diaper cup 201 to dry after the electromagnetic pumps 122-1 and 122-2 are stopped and then the electromagnetic pumps 122-1 and 122-2 are stopped. (Step S13: FIG. 19). After t4 has elapsed (step S13 / Yes: FIG. 19), the blower 101 (FIG. 18) is stopped (step S14: FIG. 19). 19) It is determined whether or not there is an end instruction, that is, whether or not there is an end operation by the caregiver (operator) (step S15: FIG. 19), and if there is an end instruction (step S15 / Yes: FIG. 19) If there is no end command (step S15 / No: FIG. 19), the process returns to step S1 to repeat the above operation.

  Here, when t1 has not elapsed since the electromagnetic pump 122-1 is stopped (step S1 / No: FIG. 19), the controller 400 (FIG. 18) has a sensor output equal to or less than a threshold value with the electromagnetic pump 122-1 stopped. If it is determined whether or not there is (step S4: FIG. 19) and it is determined that the sensor output is not below the threshold value, that is, the user 1 is not excreting (defecation) (step S4 / No), step Return to S1.

  When t2 has not elapsed since the electromagnetic pump 122-1 has started driving, that is, during regular cleaning of the diaper cup 201 (step S7 / No: FIG. 19), the process returns to step S3 and the injection of purified water is continued.

  When the electromagnetic pump 122-2 is not being driven, that is, when the user 1 is not excreting and is not in regular cleaning (step S8 / No: FIG. 19), the process proceeds to step S12, and the electromagnetic pump 122- Stop 1

  When t3 has not elapsed since the start of driving of the electromagnetic pump 122-2, that is, when the user 1 is excreting (defecation) (step S10 / No), the process returns to step S6 and the driving of the electromagnetic pump 122-2 is continued. To do.
