Abstract

A device (10) to deliver and mix water for taps (12), the device includes a mixer cartridge (30), arranged inside a monoblock (11) of the tap (12). A handle (45) regulates the mixing of the water. An actuation device is arranged above the monoblock (11). The actuator device is able to determine the opening and closing of the flow of water, with the actuation device being commanded electrically and including a membrane (20) able to cooperate with the mixer cartridge (30).

Claims

1. A device to deliver and mix water for a tap (12), said device comprising a mixer cartridge (30), arranged inside a monoblock (11) of the tap (12), a handle (45) operationally associated with the mixing cartridge (30) to regulate the mixing of the water, an actuation device, arranged above said monoblock (11), which controls an opening and closing of a flow of water through the mixing cartridge, said actuation device being commanded electrically and controlling a membrane (20) which cooperates with said mixer cartridge (30) to allow flow of water through said mixing cartridge (30).

2. Device as in claim 1, characterized in that said actuation device includes a movable element (42) which controls said membrane.

3. Device as in claim, 1 characterized in that said actuation device is commanded by drive means associated with at least a presence sensor (44).

4. Device as in claim 3, characterized in that said drive means (41) comprise at least a solenoid device.

5. Device as in claim 3, characterized in that said drive means (41) comprise at least an electric motor.

6. Device as in claim 3, characterized in that said drive means (41) are fed by batteries (36).

7. Device as in claim 3, further including a command and control unit (40), which is located above said mixer cartridge (30) in a position outside said monoblock (11), into which said actuation device (42), said drive means (41), said presence sensor (44) and an electronic circuit (43) are integrated.

8. Device as in claim 3, characterized in that timer means are associated with said drive means (41) in order to automatically de-activate said drive means (41) after a pre-determined time from when said sensor (44) detects the presence of a user.

9. Device as in claim 8, characterized in that said timer means are selectively programmable.

10. Device as in claim 6, characterized in that a unit (40) comprises housing seatings (38) for said batteries (36).

11. Device as in claim 1, characterized in that a command and control unit (40) integrally includes said handle (45) to regulate the mixing.

12. Device as in claim 11, characterized in that the function of said handle (45) is to cover and protect the components of said command and control unit (40).

13. Device as in claim 7, characterized in that said mixer cartridge (30) comprises water distribution means (18) protruding from said monoblock (11) on which said unit (40) can be coupled.

14. Device as in claim 13, characterized in that said unit (40) and said mixer cartridge (30) cooperate with reciprocal clamping means (48).

15. Device as in claim 2, characterized in that said movable element (42) is able to assume at least a first position defining a closing of the tap (12) and a second position defining an opening of said tap (12).

16. Device as in claim 15, characterized in that said movable element consists of a piston (42) able to assume an extracted position wherein the tap (12) is closed and a retracted position wherein the tap (12) is open.

17. Device as in claim 16, characterized in that said membrane (20) is housed in a chamber (26) located in communication with said mixer cartridge (30), said membrane (20) assumes a first position wherein the membrane (20) does not allow the water to be delivered from the tap (12), defined by the extracted position of said position (42), and a second position wherein the membrane (20) allows said delivery, defined by the retracted position of said piston (42).

18. Device as in claim 13, characterized in that a chamber (26) communicates with a channel (29, 31) which is selectively closed by a piston (42), and cooperates with said distribution means (18), said channel (29, 31) being closed in the extracted piston of said piston (42), and allowing said chamber (26) to be filled with water so as to maintain said membrane (20) in a first position wherein the membrane (20) does not allow the water to be delivered from the tap (12), and said channel (29, 31) being open in the retracted position of said piston (42) to allow said membrane (20) to be arranged in a second position wherein the membrane (20) allows the water to be delivered from the tap (12).

19. Device as in claim 18, characterized in that said chamber (26) communicates with a delivery outlet (21) by means of two inter-connected channels (29, 31), at least one (29 or 31) of said channels being selectively closed by said piston (42).

20. Device as in claim 18, characterized in that said membrane (20) is lowered in said first position and is raised at least partly in said second position due to an effect of the pressure of the water passing in said distribution means (18).

21. Device as in claim 18, characterized in that said membrane (20) is provided with a through hole (32), cooperating with said distribution means (18), which allows said chamber (26) to be filled with water.
