1. A sanitary washing device comprising: a nozzle including a water discharge port and configured to squirt water from the water discharge port to wash user's human private parts;a flow channel configured to supply the water to the water discharge port;a solenoid valve provided on the upstream side of the flow channel, the solenoid valve being a water supply device configured to supply the water;a sterilizing water producing device provided midway along the flow channel and being operable to produce sterilizing water which includes sterilizing ingredient;a flow channel switching valve configured to perform opening and closing water supply to the nozzle;a vacuum breaker provided on downstream of the solenoid valve and on upstream of the flow channel switching valve; anda controller configured to perform control for stopping the water supply device by closing the solenoid valve, closing the flow channel switching valve, retaining the sterilizing water produced by the sterilizing water producing device for a prescribed time in the flow channel, and then draining the sterilizing water out of the flow channel by opening the flow channel switching valve, and emptying the flow channel. 2. The device according to claim 1, further comprising: a human body sensing device configured to sense utilization by the user,wherein the controller performs control for filling the flow channel on downstream side of the sterilizing water producing device with the sterilizing water after the human body sensing device senses utilization by the user. 3. The device according to claim 2, further comprising: a heating device provided on upstream side of the sterilizing water producing device and being operable to heat water supplied to the sterilizing water producing device,wherein the controller performs hot water preparation for operating the water supply device and the heating device to drain the water from the water discharge port when the human body sensing device senses the user, and the controller controls a timing to activate the sterilizing water producing device after starting the hot water preparation based on a time period required to fill the flow channel on the downstream side of the sterilizing water producing device with the sterilizing water. 4. The device according to claim 3, wherein the controller starts to activate the sterilizing water producing device during or after completing the hot water preparation. 5. The device according to claim 3, further comprising: a first temperature sensing device configured to sense temperature of the water heated by the heating device,wherein the controller starts to activate the sterilizing water producing device when the temperature sensed by the first temperature sensing device reaches a preset temperature. 6. The device according to claim 3, wherein the controller starts to activate the sterilizing water producing device after lapse of a fixed time from the start of the hot water preparation. 7. The device according to claim 3, further comprising: a second temperature sensing device configured to sense temperature of water supplied to the heating device,wherein the controller sets a suitable temperature continuation time required to fill the flow channel on the downstream side of the sterilizing water producing device with the water heated by the heating device based on the temperature sensed by the second temperature sensing device, and starts to activate the sterilizing water producing device based on the suitable temperature continuation time so that a timing to stop activating the sterilizing water producing device coincides with or precedes a timing to complete the hot water preparation. 8. The device according to claim 3, further comprising: a second temperature sensing device configured to sense temperature of water supplied to the heating device,wherein the controller includes a memory device configured to store a suitable temperature continuation time required to fill the flow channel on the downstream side of the sterilizing water producing device with the water heated by the heating device based on the temperature sensed by the second temperature sensing device, and starts to activate the sterilizing water producing device by referring to a past one of the suitable temperature continuation time stored in the memory device so that a timing to stop activating the sterilizing water producing device coincides with or precedes a timing to complete the hot water preparation. 9. The device according to claim 2, wherein the human body sensing device is a room entry sensor operable to sense entry of a user into a toilet room. 10. The device according to claim 2, further comprising: a toilet lid,wherein the human body sensing device is a toilet lid opening/closing sensing device operable to sense an opening motion of the toilet lid. 11. The device according to claim 1, wherein the controller performs a cleaning step configured to clean the nozzle, and performs the control for retaining continuously subsequent to the cleaning step. 12. The device according to claim 1, wherein the controller performs the control for retaining after the user ceases to be sensed. 13. The device according to claim 12, wherein the controller senses leaving of the user from a toilet seat. 14. The device according to claim 1, wherein the controller regularly performs the control for retaining and the control for draining. 15. The device according to claim 1, further comprising: a human body sensing device operable to sense the user,wherein the controller performs the control for retaining when the human body sensing device senses the user, and the controller performs the control for draining in response to receipt of a signal directing to perform washing of the human private parts. 16. The device according to claim 1, further comprising: a nozzle cleaning device including a water discharge portion and configured to clean a surface of the nozzle with water discharged from the water discharge portion,wherein the controller discharges the sterilizing water from the water discharge portion, and then completes the hot water preparation by discharging the sterilizing water from only the water discharge port of the nozzle. 17. The device according to claim 1, wherein the sterilizing water producing device is an electrolytic cell. 18. The device according to claim 17, wherein flow rate of water supplied to the electrolytic cell in producing the sterilizing water is lower than maximum flow rate of water flowing in the electrolytic cell.
