Abstract

A modular system for automatically controlling the operation of a water faucet comprises an electrically operable valve for installation in line of a water supply line to the faucet for controlling water flow to the faucet; a sensor for detecting the presence of an individual within a predetermined range of the sensor; a controller for connecting to the valve and the sensor for receiving a detection signal from the sensor and for operating the valve in response to the signal; and releasable connectors for connecting the valve and the sensor to the controller.

Claims

1. A modular system for automatically controlling the operation of a water dispensing fixture, comprising:

a) electrically operable valve means having an operating voltage eliminating the need for conduit while enhancing safety to the installer and user for installation in line of a water supply line to the fixture for controlling water flow to the fixture, said valve means including a connector means;

b) sensor means for detecting the presence of an individual within a predetermined range of said sensor means;

c) control means for connection with said valve means and said sensor means for receiving a detection signal from said sensor means and for causing said valve means to operate in response to the detection signal, and said control means including a plurality of connector means;

d) a first flexible cord for interconnecting said valve means to said control means, said cord having connector means at the opposite ends thereof for interconnection with cooperating ones of said connector means of said control means and said valve means;

e) each of said connector means is a plug, or a cooperating receptacle; and

,

f) a second flexible cord extends from said sensor means and has a connector means at the remote end thereof for interconnection with a cooperating connector means of said control means.

2. A modular system as in claim 1, wherein:

a) each of said connector means of said first flexible cord includes an attachment plug.

3. A modular system as in claim 1, wherein,

a) said valve means connector means includes a receptacle;

b) said control means connector means includes at least first and second receptacles;

c) said sensor means includes a first flexible cord with an attachment plug for connecting to said first receptacle outlet of said control means; and

,

d) a second flexible cord includes an attachment plug on one end thereof for connecting one of said attachment plugs to said valve means receptacle outlet and for connecting the other of said attachment plugs to said second receptacle outlet of said control means.

4. A modular system as in claim 3, wherein:

a) said valve means includes an enclosure having an opening; and

b) said receptacle of said valve means is disposed within said opening so that said receptacle is accessible from the exterior of said enclosure.

5. A modular system as in claim 3, wherein:

a) said control means includes an enclosure with first and second openings; and

b) said first and second receptacles of said control means are disposed within said first and second openings, respectively, so that each of said first and second receptacles are accessible from the exterior of said enclosure.

6. A modular system as in claim 1, wherein:

a) said attachment plugs and receptacles include means for assuring insertion in a predetermined orientation of each of said attachment plugs into a respective receptacle.

7. A modular system as in claim 1, wherein:

a) each of said plugs includes at least three leads; and

b) each of said receptacles includes means for receiving said at least three leads.

8. A modular system as in claim 3, wherein:

a) each of said plugs has a key; and

b) each of said receptacles has a keyway for receiving said key.

9. A bathroom assembly, comprising:

a) a sink;

b) a water faucet operably associated with said sink;

c) a water supply line operably associated with said faucet;

d) electrically operable valve means having an operating voltage eliminating the need for conduit while enhancing safety to the installer and user disposed in said water supply line for controlling water flow to said faucet, said valve means including a connector means;

e) first sensor means disposed adjacent said sink and said faucet for detecting the presence of an individual within a predetermined range of said sink and faucet;

f) control means operably associated with said valve means and said sensor means for receiving a detection signal from said sensor means and for causing said valve means to operate in response to the signal, said control means including a plurality of connector means;

g) a first flexible cord for interconnecting said valve means to said control means, said first flexible cord having connector means at the opposite ends thereof for interconnection with cooperating ones of said connector means of said control means and said valve means;

h) each of said connector means is a plug or a cooperating receptacle; and

,

i) a second flexible cord extends from said sensor means and has a connector means at the remote end thereof for interconnection with a cooperating connector means of said control means.

10. A bathroom assembly as in claim 9, wherein:

a) each of said connector means of said first flexible plug includes an attachment plug.

11. A bathroom assembly as in claim 9, wherein:
