PROBLEM TO BE SOLVED: To provide a cleaning device for collected water in which both maintenance of activity of aerobic bacteria in a cleaning part and control of increase in anaerobic bacteria in the case for unnecessitating cleaning of collected water are enabled by less suppressing power consumption. SOLUTION: When use and nonuse of the cleaning device are distinguished (S3) and it is distinguished that the cleaning device is not used, a pump for circulating collected water through a cleaning part is intermittently actuated (S10). Thereby, replacement of collected water remaining in the cleaning part and collected water except the cleaning part is performed sometimes. Oxygen dissolved in collected water except the cleaning part is sufficiently supplemented to the cleaning part. In this case, such a method is adopted that an air pump directly sending air to the cleaning part is intermittently actuated instead of intermittent actuation of the pump. |
