Title: METHOD AND SYSTEM FOR CONTROLLING WATER PURIFIER
Abstract:
A method for controlling a water purifier comprises the following steps: configuring a water quality tester for concentrated water, to obtain a TDS value of the concentrated water by using the water quality tester; discharging the concentrated water if the TDS value exceeds a specified threshold; and if the TDS value is less than the threshold, returning the concentrated water to raw water for filtering. A system for controlling a water purifier comprises: a configuring unit (201), used for configuring a water quality tester for concentrated water, to obtain a TDS value of the concentrated water by using the water quality tester; a discharging unit (202), used for discharging the concentrated water if the TDS value exceeds a specified threshold; and a filtering unit (203), used for returning, if the TDS value is less than the threshold, the concentrated water to raw water for filtering.
