A system and method of Touch Free Automatic faucet controlled by electronic sensors provides a Primary-Water-Flow-Mode, a Continue-Water-Flow-Mode, a Temperature-Control-Mode, a Faucet-Pause-Mode, an Adjust-Water-Flow-Mode and a Flow-Temperature-Default-Setting-Mode for users to control faucet water flow and water temperature without touching any parts of faucet body. The system comprises at least three electronic sensors (infrared sensors), a logical processor circuit board, an electricity power supply package, a water flow control valve assembly, a temperature control valve assembly, at least one faucet body housing and at least one inlet fluid line. From the outputs of the sensors, the logical processor responds to the flow control valve assembly and to the temperature control valve assembly to control water flow and temperature to the faucet spout. This Touch Free Automatic faucet hence provides an easy-convenient operation, water conservation and personal hygiene protection for commercial and residential applications.
A system and method of touch free automatic faucet comprising:
A logic function (in this case, activation or deactivation of Continue-Water-Flow-Mode) is triggered by a combination of function of two sensors (in this case, Sensor A and Sensor B of the secondary sensors) is claimed.
The default settings of water flow and temperature are programmed in logic processor through the combination function of the paired secondary sensors (Sensor A and Sensor B) and the paired tertiary sensors (Sensor D and Sensor E) (Flow-Temperature-Default-Setting-Mode).
Dependencies are inferred from the claim text.
