Method for intelligent control of flushing for water quality purification and water purifier

Abstract

The invention discloses a method for intelligent control of flushing for water quality purification and a water purifier thereof. The method comprises the following steps of S1, setting the total purifying impurity parameter value G of a filtering device of the water purifier; S2, obtaining the impurity parameter value H1 at the water intake end of the filtering device of the water purifier; S3, obtaining the accumulated total water usage amount Q in the flushing cycle; S4, calculating the rated purifying water amount of the filtering device of the water purifier, namely Q1=G / H1; S5, judging,if Q is smaller than Q1, performing no flushing; if Q is greater than or equal to Q1, executing a flushing mode; S6, after the flushing is finished, zeroing the total water usage amount Q, and repeating the steps S2 to S5. The method has the advantages that the flushing time is judged according to the total purifying impurity parameter value of the filtering device, so that the filtering device can be flushed at proper time, the efficiency of the filtering device is fully realized, and the resource is saved; two standby control plans are arranged for the water purifier, such as a removal ratejudging method and a filtering value comparing method, so that the judgment of the flushing time is more reliable.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a method for intelligently controlling flushing of water quality purification and a water purifier. Background technique [0002] The function of the water purifier is to purify the water quality, and remove residual chlorine, turbidity, organic matter and other impurities in the water through these purification materials such as activated carbon and quartz sand. After using for a period of time, the content of impurities in the purification material will increase, and it is necessary to wash out the impurities in the purification material to ensure the purification effect. This process is called flushing. Existing household water purifiers, its flushing cycle is generally set by manual fixed flushing time interval, after the use time of water purifier reaches this set time interval, start flushing. [0003] The above method for setting the fixed flushing cycle is simple to imp...
