Speed and one negative-feedback of pressure initiation measured, specific as follows:
In the second preset time T 1, the pressure in the continuous signal piping component 2 of control unit 4 is less than second pressure threshold
Value P2, control unit 4 then determine that water source is exsiccosis at this time, and control water pump 1 stops working, and is issued by reminding unit 7
Water deficient reminding function signal is not connected with reminding user that need to check whether for 5 water shortage of external water source or pipeline assembly 2.
When external water source 5 supplies water and the connection of pipeline assembly 2 is all normal, control unit 4 controls water pump 1 and works normally, when
When pressure increase is greater than first pressure threshold value in pipeline assembly 2, control unit 4 controls water pump by electric-motor drive unit 6
Motor speed reduces；When in pipeline assembly 2 pressure become smaller be, for example, less than second pressure threshold value when, control unit 4 pass through motor drive
Moving cell 6 controls pump motor revolving speed and increases, so that the pressure in pipeline assembly 2 maintains a certain range when drawing water
Interior, regardless of whether the hydraulic pressure of external water source 5 stable, the function that can guarantee to drink water stablizes water outlet, realize the flow of water outlet not by
The influence of the hydraulic pressure of external water source 5.
When water pump 1 works normally, if the change rate of the pressure in pipeline assembly 2 is greater than default change rate threshold value,
Illustrate hydraulic pressure increase/reduction suddenly of external water source 5, control unit 4 can be immediately controlled water pump 1 and stop working, until pipeline group
When pressure is restored to normal value in part 2, water pump 1 is controlled again and continues to work normally.
To sum up, according to the utility model proposes water dispenser control device, pass through the pressure being arranged in pipeline assembly
Pressure in detection unit signal piping component, and then the pressure in pipeline assembly less than the second preset pressure threshold value and continues
When time is greater than the second preset time, judges that water dispenser is in exsiccosis, pass through the control list being connected with pressure sensing cell
Member control water pump stops working.The revolving speed of motor in water pump is controlled so that pipeline assembly by the pressure in pipeline assembly as a result,
