Patent ID: 8070072

Claim:
A method for controlling a digital shower system, wherein the digital shower system comprises a cold water inlet pipe, a hot water inlet pipe, a mixing device with one end communicated with both the cold water inlet pipe and the hot water inlet pipe, an outlet pipe communicated with the other end of the mixing device, at least one water outlet communicated with the other end of the outlet pipe, a digital user interface, and a control unit, the mixing device is provided with a temperature sensor, the outlet pipe is provided with a control valve, the temperature sensor and the control valve are respectively electrically connected to the control unit, and a user inputs a preset outlet water temperature through the digital user interface, the method comprising: Step A1: actuating the digital shower system for operation (power-on); Step A2: detecting whether the system is in order or not, and if not, generating an error message; otherwise, performing the next step; Step A3: entering a ready mode (RM), for discharging in advance a water flow in the outlet pipe that does not reach the preset outlet water temperature; Step A4: entering a shower mode (SM), wherein a desired message is input through the digital user interface, the control valve is controlled by the control unit to make the water continuously output from the water outlet and remain at the same temperature as the preset outlet water temperature, and several preset power-off conditions are provided; and Step A5: automatically turning off the digital shower system by the preset power-off conditions (power-off); wherein the digital user interface is provided with a plurality of keys at least comprising several function keys and several number keys, and a control method of a first preset power-off condition out of the preset power-off conditions comprises: Step B1: turning on the SM; and Step B2: determining whether the keys of the digital user interface are used in five minutes or not, and if yes, entering a setting screen and completing the setting of the water outlet by the digital user interface; otherwise, performing Step A5.
