The optimal water flow of the synthesis of water purifier under various flows value and different water routes pressure is collected, and by this cohersive and integrated data
In the control program of writing controller, controller, according to the flow value receiving and water route pressure, obtains according to control program then
Go out optimal water flow；Or the optimal water flow of the synthesis of the water purifier under different inflow temperatures and various flows value is entered
Row collects, and by the control program of this cohersive and integrated data writing controller, then controller according to the inflow temperature receiving with
Flow value, draws optimal water flow according to control program.
Preferably, the control parameter that controller 22 receives is inflow temperature, water route pressure and the flow value of water purifier, its
In, it is big that the impact coefficient to purifier water outlet flow for the water route pressure is more than the impact coefficient to purifier water outlet flow for the inflow temperature
In the impact coefficient to purifier water outlet flow for the flow value, the change of the preferential control parameter larger according to impact coefficient of controller 22
Change, output pump motor adjustment signal.
Specifically, drawn according to test of many times, the impact coefficient to purifier water outlet flow for the water route pressure is more than into water temperature
Degree to purifier water outlet flow impact coefficient be more than the impact coefficient to purifier water outlet flow for the flow value, inflow temperature,
When water route pressure and flow value change simultaneously, controller is adjusted to pump motor, according to warp based on pressure first by water
Test or water purifier structure or sensor mounting location difference, each control parameter impact coefficient magnitude relationship can change
Become, for example can arrange inflow temperature is the impact coefficient maximum to purifier water outlet flow effect, and the present embodiment is preferably with water
Road pressure is the maximum parameter of impact coefficient, is secondly inflow temperature, and again for flow value, controller 22 first determines whether that water route is pressed
Whether power exceedes default pressure value or pressure limit, output pump motor adjustment signal, adjusts the |input paramete of motor, thus
Change the runnability of pump motor, then the output pressure of adjustment water pump or output flow, correct reverse osmosis membrane goes out current
Amount, when water route pressure is not less than default pressure or pressure limit, then controller judge again inflow temperature and flow value with pre-
Definite value or the magnitude relationship of preset range.
The purifier water outlet flow control system that this utility model embodiment provides, by obtaining the water inlet at water purifier water source
Temperature, water route pressure and flow value, and by adjusting signal, the output pressure of water pump and/or output stream in adjustment water purifier
