Abstract

Claims (36)

1 . A rinsing lavatory comprising:

a basin having at least a first side and a second side;

at least one tube connecting a water supply to a first plurality of nozzles on the first side of the basin and a second plurality of nozzles on a second side of the basin;

a water treatment device between the water supply and the at least one tube;

at least one valve configured to open the first plurality of nozzles or the second plurality of nozzles to provide rinsing water to the first side of the basin or the second side of the basin from the water treatment device through the at least one tube in response to an input signal; and

a motor configured to drive a shuttle associated with the at least one tube and configured to open the at least one valve in a sequence for a sweeping motion of the rinsing water.

2 . The rinsing lavatory of claim 1 , wherein the at least one tube includes a first tube connected to a first plurality of valves and a second tube connected to a second plurality of valves.

3 . The rinsing lavatory of claim 1 , wherein the water treatment device includes an electrolyzed water generator.

4 . The rinsing lavatory of claim 1 , wherein the water treatment device add a chemical to the water supply.

5 . The rinsing lavatory of claim 1 , wherein the water treatment device includes a venturi configured to induct a treatment additive into the water supply.

6 . The rinsing lavatory of claim 1 , further comprising:

a user input configured to trigger the input signal.

7 . The rinsing lavatory of claim 1 , wherein the at least one valve includes a plurality of valves for the first plurality of nozzles.

8 . The rinsing lavatory of claim 7 , further comprising:

a controller configured to individually open each of the plurality of valves in a sequence for a sweeping motion of the rinsing water.

9 . The rinsing lavatory of claim 1 , further comprising:

a worm gear coupled to the shuttle and driven by the motor.

10 . The rinsing lavatory of claim 1 , wherein the basin is polygonal.

11 . The rinsing lavatory of claim 1 , wherein the basin is rectangular.

12 . The rinsing lavatory of claim 1 , further comprising:

a curved and sloped surface on the first side of the basin.

13 . The rinsing lavatory of claim 1 , further comprising:

a slot drain extending across the second side of the basin.

14 . The rinsing lavatory of claim 1 , wherein the at least one tube connects the water supply to a third plurality of nozzles on a third side of the basin and a fourth plurality of nozzles on a fourth side of the basin.

15 . The rinsing lavatory of claim 1 , wherein the first plurality of nozzles or the second plurality of nozzles includes a fluidic oscillator.

16 . A rinsing lavatory comprising:

a basin;

at least one tube connecting a water supply to a plurality of nozzles;

a water treatment device between the water supply and the at least one tube; and

a motor configured to drive a shuttle associated with the at least one tube and configured to open at least one valve in a sequence for a sweeping motion of water.

17 . A method for rinsing a lavatory, the method comprising:

receiving an input signal for initiation of a rinse cycle;

generating a treatment instruction for a treatment device;

generating an actuation instruction for a motor configured to drive a shuttle and configured to open at least one valve; and

providing, to the lavatory, water treated by the treatment device in a pattern formed by the motor and the shuttle.

18 . The method of claim 17 , wherein the treatment device is configured to generate ozone or electrolyzed water.
