  • the electronic control unit 120 ′′ is electrically connected to the fifth sensor 122 e (e.g., the fifth sensor 122 e which is electrically connected to the first microprocessor 132 of the main control circuit board 130 ′′ is the same as the first to third sensors 122 a, 122 b, 122 c which are electrically connected to the first microprocessor 132 of the main control circuit board 130 shown in FIG. 2 ) for receiving the fifth sensing signal and then generating a driving signal.
  • the potable water control unit 190 is electrically connected to the second microprocessor 142 of the auxiliary control circuit board 140 ′′ through another signal connection line (not shown).
  • the potable water control unit 190 is communicated with the inlet 117 of the shell 110 ′′, and controls whether the potable water is supplied according to the driving signal.
  • the fifth sensor 122 e can be an infrared sensor or a microwave sensor.
  • the potable water control unit 190 can be a solenoid valve.
  • a touch free automatic type potable water supply step includes the following example of this embodiment: Referring to FIG. 9 a , when the fifth sensor 122 e senses an appearance of an external object (e.g., a hand 104 ), the fifth sensing signal is a potable water open signal, whereby the potable water of the touch free automatic type water supply device 100 ′′ is supplied; and referring to FIG. 9 b , when the fifth sensor 122 e senses a disappearance of the external object, the fifth sensing signal is a potable closed signal, whereby the potable water of the touch free automatic type water supply device 100 ′′ is not supplied.
  • the first microprocessor 132 receives the potable water open signal or the potable water closed signal, and then generates a control signal.
  • the second microprocessor 142 receives the control signal, and then generates a driving signal.
  • the potable water control unit 190 controls whether the potable water of the touch free automatic type water supply device 100 ′′ is supplied according to the driving signal.
  • the touch free automatic type water supply device 100 ′′ of the present disclosure can control whether the city water and the potable are supplied respectively.
