S01judging whether the reverse osmosis water purifier is in a working state or a standby state, and if the reverse osmosis water purifier is in the working state, executing the step S1If in the standby state, executing the step S11；
S11Detecting whether the standby time of the reverse osmosis water purifier to be washed exceeds a preset time threshold value, if so, flushing the reverse osmosis water purifier to be washedThe washing time is set to a third time period, and then step S is performed3And if not, continuing to wait.
Preferably, the third time period is 20 seconds.
Preferably, the preset time threshold is 3 days.
Preferably, the first time period and the second time period are both 1 second.
Preferably, step S1The corresponding relation between the water making time and the flushing time comprises:
if the water making time is less than 1 minute, the flushing time is 3 seconds;
if the water making time is more than or equal to 1 minute and less than 5 minutes, the flushing time is 5 seconds;
if the water making time is more than or equal to 5 minutes and less than 10 minutes, the flushing time is 8 seconds;
and if the water making time is more than or equal to 10 minutes, the flushing time is 12 seconds.
