Title:
WATER PURIFIER RECOVERY RATE CONTROL METHOD, APPARATUS AND SYSTEM, AND WATER PURIFIER
Document Type and Number:
WIPO Patent Application WO/2021/077891
Kind Code:
A1
Abstract:
The present application relates to a water purifier recovery rate control method, apparatus and system, and a water purifier. During an operation process of the water purifier, a data collection apparatus can collect real-time water quality operation parameters of the water purifier and send same to a data processing host, and a concentrated water Langelier saturation index (LSI) of the water purifier in a real-time state can then be obtained by means of performing analysis according to the water quality operation parameters. When the concentrated water LSI of the water purifier is greater than or equal to a preset critical LSI, the data processing host can adjust the recovery rate of the water purifier by means of a recovery rate control apparatus to cause the water purifier to operate at a rational recovery rate. By means of the solution, during the operation process of the water purifier, the recovery rate of the water purifier can be adjusted in real time, according to water quality characteristics of the water purifier, to be in a state matching the location of the water purifier. Therefore, the water yield of the water purifier is guaranteed, and the blockage of a wastewater electromagnetic valve of the water purifier is avoided; at the same time, waste of raw water can also be effectively prevented; and the water purifier has the advantage of a strong water purification reliability.
