Control device for faucet assemblies
First Claim
1. A control device for faucet assemblies, the faucet assemblies comprising:
- a faucet spout with a first water outlet and a second water outlet;
a first water supply pipe communicating with the first water outlet, anda second water supply pipe communicating with the second water outlet, the second water supply pipe containing a water outlet pipe section connected with the second water outlet and a first water inlet pipe section and a second inlet pipe section communicating with the water outlet pipe section, being characterized in that;
the control device comprises a first solenoid valve provided on the first water inlet pipe section to control on-off of the first water inlet pipe section;
a second solenoid valve provided on the second water inlet pipe section to control on-off of the second water inlet pipe section;
a capacitive touching unit disposed on the faucet spout, the capacitive touching unit for sensing touch time of human body and emitting touch signal; and
a second control unit electrically connected to the capacitive touching unit to switch the first solenoid valve and the second solenoid valve in accordance with a touch signal of the capacitive touching unit to control opening and closing of the second water outlet, when touch time is less than a first predetermined time, turning on the second solenoid valve, when touch time is greater than a second predetermined time, turning on the second solenoid valve;
the second water outlet of the faucet assemblies is connected to a manual valve which connects a hot water and a cold water, and water outlet temperature is adjusted by the manual valve;
the hot water passes through the first solenoid valve, a house and a throat section on the first inlet pipe section and the heater into the first water outlet, a third solenoid valve for backflow hot water is provided between the heater and the first water outlet;
the cold water passes through the second solenoid valve, the house and the throat section disposed on the second inlet pipe section into the first water outlet;
the control device also includes a delay switch for adjusting the second control unit for setting delay turn-off time;
wherein the second control unit does not receive touch signal of the capacitive touch unit again within a continuous delay turn-off time after receiving last touch signal of the capacitive touch unit, a control module controlling the first solenoid valve or the second solenoid valve to be closed.
