초록 ▼

A faucet supplies water at a computer controlled temperture. Hot and cold water valves are connected to hot and cold water supplies. A mixing connection is attached between the valves for mixing the hot and cold water together and supplying it at a faucet discharge. Each valve has a movable valve member which can be moved toward and away from a valve seat to control the flow of hot or cold water. A stepper motor is connected to each of the valve members and can be controlled by a digital error signal to rotate, in steps, either to increase or decrease the flow of hot or cold water. A temperature sensor is provided at the faucet outlet for sensing the actual temperature. A microcomputer receives signals corresponding to the actual temperature. The actual temperature is compared to a selected set point temperature which is programmed into the microcomputer. If an error exists between the actual and set point temperatures, control signals are supplied to the stepper motors for changing the flow of hot or cold water to move the actual temperature toward the set point temperature.

대표청구항 ▼

A faucet with computer controlled temperature comprising: a hot fluid supply connection, for supplying hot fluid to said faucet; a cold fluid supply connection, for supplying cold fluid to said faucet; hot and cold fluid valves connected, respectively, to said hot and cold fluid supply connections, said hot and cold valves each having a valve seat and a valve member movable with respect to said valve seat to control a flow of fluid through said valve, with each said valve member being further disposed so that one of its ends is threaded and so that the opposite end thereof has attached thereto a seal which is engagable with said associated valve seat; first and second stepper motors connected, respectively, to said hot and cold fluid valves for moving said hot and cold valve members, respectively, in relationship to their associated valve seats, said stepper motors each having a shaft and a threaded connection fixed to said shaft, each stepper motor shaft having a knob connected thereto for manual rotation of said shaft, and said threaded connection being disposed in threaded engagement with said threaded end of said valve member; a mixing connection connected between said hot and cold fluid valves, for receiving the flow of hot and cold fluids and mixing them together and discharging them as a mixed flow of fluid; a temperature sensor connected to said mixing connection for generating an analog signal corresponding to the actual temperature of the mixed fluid; analog-to-digital conversion means connected to said temperature sensor for converting said analog signal into a digital temperature signal corresponding to the actual temperature of the mixed fluid; a microcomputer connected to said conversion means for computing an error value between the actual temperature and a selected temperature and for applying a digitally implemented feedback control algorithm to said error value to generate a feedback control signal for controlling the fluid flow through said hot and cold valves; and logic means connected to said microprocessor and also to said first and second stepper motors, for receiving said control signal and for controlling said stepper motors in response to said control signal, to move said hot and cold valve members so as to cause the actual temperature of the mixed fluid to approach the selected temperature therefor.
