Expire prompt information out.
Specifically, with the increase for using the time, the impurity in water can block filter core, and the water speed processed of purifier can be got over
Come slower, therefore, the water speed V processed that expires when RO filter element life expires can be precomputed as the case may be, it then can be with
Water speed processed is compared with V, if water speed processed is less than the preset water speed V processed that expires, has illustrated RO filter element life
It expires.To guarantee purifier, it can control purifier and issue the prompt information that expires, to remind user to replace RO filter core.Its
In, prompt information can be light, text or voice prompting etc..
Further, in an embodiment of the present invention, the preset water speed V processed that expires can be obtained according to the following formula:
V=K*Vo,
Wherein, V is the default water speed processed that expires, and K is adjustable between 0 to 1, and Vo is the initial water speed processed of purifier.
It is appreciated that can adjust the value of K according to the raw water quality before filtering, general K is 0.8 or so.
In conclusion the filter element life detecting method of purifier according to an embodiment of the present invention, first detection water storage dress
Interior water situation of change is set, the water speed processed of purifier is then obtained according to water situation of change, and according to water speed processed
Judge whether the service life of RO filter core expires, to eliminate influence of the water quality to RO filter core, improves the judging service life of RO filter core
