Touchless faucet

1. A touchless faucet comprising:

a faucet body having a first compartment and a second compartment, the second compartment having first and second water ports at a rear of the faucet body for coupling to respective water lines to couple the faucet to a panel or wall;

at least one control board disposed in the first compartment;

an IR sensor disposed in the first compartment and communicatively coupled to the at least one control board; and

a solenoid disposed in the second compartment and communicatively coupled to the at least one control board.

2. The touchless faucet according to claim 1 , further comprising a capacitive sensor coupled to a front of the faucet body and communicatively coupled to the at least one control board, wherein the faucet is configured to be activated by the IR sensor or the capacitive sensor.

3. The touchless faucet according to claim 1 , further comprising a bottom cover coupled to a bottom of the faucet body to close the first compartment, and a rear cover coupled to a rear of the faucet body to hold the solenoid in position in the second compartment.

4. The touchless faucet according to claim 3 , wherein the rear cover is received in a recessed area at the rear of the faucet body and is substantially flush with the rear of the faucet body.

5. The touchless faucet according to claim 1 , wherein the faucet body includes a first port at a rear of the faucet body for receiving a vent valve, and a second port at the rear of the faucet body for receiving the solenoid.

6. The touchless faucet according to claim 5 , wherein the second port is in fluidic communication with the first and second water ports to receive fluid in a mixing chamber.

7. The touchless faucet according to claim 5 , further comprising the vent valve positioned in the first port, the vent valve including a valve body having an inlet, an internal cavity in communication with the inlet, an outlet in communication with the internal cavity, and a ball disposed in the internal cavity to close the outlet when pressurized.

8. The touchless faucet according to claim 1 , wherein the solenoid has an inlet for receiving fluid from a mixing chamber formed in the second compartment and an outlet for delivering the fluid from the mixing chamber to an aerator.

9. The touchless faucet according to claim 8 , wherein the IR sensor is configured to sense a presence of a user, which is communicated to the solenoid to open the solenoid to allow fluid flow through the second compartment to the aerator.

10. The touchless faucet according to claim 1 , further comprising a rear cover received in a recessed area at a rear of the faucet body and coupled to the rear of the faucet body to hold the solenoid in position in the second compartment.

11. The touchless faucet according to claim 10 , wherein the faucet body includes a first port in the recessed area for receiving a vent valve, and a second port in the recessed area for receiving the solenoid.

12. The touchless faucet according to claim 1 , wherein the at least one control board includes a first control board and a second control board, where the solenoid is communicatively coupled to the first control board and the IR sensor is communicatively coupled to the second control board.

13. The touchless faucet according to claim 12 , wherein the first control board is positioned in the first compartment rearward of the aerator, and the second control board is positioned in the first compartment forward of the aerator.

14. A touchless faucet comprising:

a faucet body having a first compartment and a second compartment;

an aerator coupled to the faucet body at a bottom of the faucet body and configured to receive fluid from the flow passage;

a control board disposed in the first compartment;

a solenoid disposed in the second compartment and communicatively coupled to the control board; and

an IR sensor disposed in the first compartment for sensing a presence of a user below the faucet.

15. The touchless faucet according to claim 14 , further comprising a capacitive sensor coupled to a front of the faucet body for sensing contact by a user.

16. The touchless faucet according to claim 14 , further comprising a second control board, wherein the second control board is communicatively coupled to the control board, and wherein the IR sensor is communicatively coupled to the second control board.

17. The touchless faucet according to claim 15 , wherein the faucet includes a first activation mode where the faucet is activated by the IR sensor sensing the presence of the user and a second activation mode where the faucet is activated by the capacitive sensor sensing contact by the user.

18. A touchless faucet comprising:

a faucet body having a first compartment and a second compartment;

at least one control board disposed in the first compartment;

an IR sensor disposed in the first compartment and communicatively coupled to the at least one control board;

a solenoid disposed in the second compartment and communicatively coupled to the at least one control board; and

a rear cover coupled to a rear of the faucet body to hold the solenoid in position in the second compartment, the rear cover being received in a recessed area at the rear of the faucet body.

19. The touchless faucet according to claim 18 , wherein the IR sensor is configured to sense a presence of a user, which is communicated to the at least one control board, and the at least one control board is configured to communicate the presence to the solenoid to open the solenoid to allow fluid flow through the second compartment to an aerator.

20. The touchless faucet according to claim 18 , wherein the rear cover is substantially flush with the rear of the faucet body.
