Abstract

A lavatory system has a cabinet including a base, a basin and a head extending above the basin. A water outlet/sensor is mounted in the head. A water supply line is connected to the water outlet. A solenoid valve in the water supply line controls the flow of water through the water supply line. A circuit board sends electrical signals to the solenoid valve for opening and closing the valve upon receipt of indications from a sensor as to whether a user hands is present or not. The solenoid valve, shut off valve, circuit board and sensor are mounted in the head with a sloped surface towards the basin. A manual shutoff valve mounted in the head is included in the supply line.

Claims

1. A lavatory comprising:

a cabinet;

a basin supported by the cabinet;

a head extending above the basin;

at least one water outlet mounted in the head;

a water supply line connected to the water outlet and including a solenoid valve for controlling flow through the water supply line;

a circuit board electrically connected to the solenoid valve for opening and closing said valve; and

a sensor electrically connected to the circuit board for supplying a signal thereto when a user is detected, the solenoid valve, circuit board, sensor, and water supply line being mounted in the head.

2. The lavatory of claim 1 wherein the head further comprises a lower portion and an upper portion which is sloped downwardly toward the basin whereby the slope allows the gravitational flow of any liquid that may have leaked from the upper portion into the basin below.

3. The lavatory of claim 1 wherein the water supply line further comprises a water shutoff valve.

4. The lavatory of claim 1 wherein the solenoid valve, circuit board and sensor are mounted on a standoff in the interior of the head.

5. The lavatory of claim 1 further comprising at least one soap dispenser mounted in the head.

6. A lavatory comprising:

a cabinet;

a basin supported by the cabinet;

a head extending above the basin;

at least one insert assembly mounted in the head, said insert assembly including a water outlet, a sensor, and at least one water passage channel;

a water supply line connected to the water outlet and having a solenoid valve for controlling flow through the water supply line;

a circuit board electrically connected to the solenoid valve for opening and closing said valve;

said sensor electrically connected to the circuit board for supplying a signal thereto when a user is detected, the solenoid valve and circuit board being mounted in the head.

7. The lavatory of claim 6 wherein the head further comprises a lower portion and an upper portion which is sloped downwardly toward the basin whereby the slope allows the gravitational flow of any liquid that may have leaked from the upper portion into the basin below through the water passage channel.

8. The lavatory of claim 6 wherein the solenoid valve and circuit board are mounted on a standoff in the interior of the head.

9. The lavatory of claim 6 wherein the water supply line further comprises a water shutoff valve.

10. The lavatory of claim 6 further comprising at least one soap dispenser mounted in the head.
