Abstract

Novel plumbing products, including faucets, are fabricated, e.g., using metallic 3-dimensional or other 3-D printing techniques, to have complex geometries, such as multiple channels that may diverge and re-converge near the spout. The geometries of the various channels can resemble interwoven net-like patterns that define various shapes between the channels. The plumbing fixtures may be formed from one or more of stainless steels, INCONEL, brass, bronze, polycarbonate, PVC, acrylics, rigid polyolefins, PET, carbon fiber, AES, or other plumbing fitting suitable corrosion resistant materials. In some embodiments, the handles of an exemplary faucet can include the same or a similar multiple channel configuration as the spout, providing an advantageously, aesthetically pleasing faucet system. In exemplary embodiments, faucet spouts and their handles are formed so as to couple to standard faucet underbodies, standard valve platforms, or standard threaded hose/waterway connections.

First claim

What is claimed is:

1. A faucet, comprising:
a water chamber;
a plurality of water channels fluidly connected to the water chamber, wherein each of the plurality of water channels is configured to transport water from a respective water inlet proximate to the water chamber to a respective water outlet;
wherein the plurality of water channels forms a base portion of the faucet configured to transport water upward from the respective water inlets through the base portion;
wherein the plurality of water channels forms a spout portion of the faucet configured to transport water downward through the spout portion toward the respective water outlets;
wherein a first channel of the plurality of channels terminates, at its respective water outlet, in the spout portion of the faucet, at a first vertical height, and
wherein a second channel of the plurality of channels terminates, at its respective water outlet, in the spout portion of the faucet, at a second vertical height lower than the first vertical height.

2. The faucet of claim 1 , the first channel and second channel are configured such that water dispensed from the outlet of the first channel flows over and along an upper surface of an outer wall of the second channel.

3. The faucet of claim 1 , wherein the plurality of water channels comprise six water channels.

4. The faucet of claim 1 , wherein the components of the faucet are formed so as to couple to standard faucet underbodies, standard valve platforms, or standard threaded hose/waterway connections.

5. The faucet of claim 1 , wherein a cross-sectional area of all of the plurality of water channels in aggregate is greater than or equal to about 7 mm 2 .

6. The faucet of claim 1 , wherein the average diameter of the plurality of water channels is greater than or equal to about 1 mm.

7. The faucet of claim 1 , wherein the faucet is formed of one or more of stainless steels, INCONEL, brass, or bronze, by metallic 3-D printing.

8. The faucet of claim 7 , wherein the faucet is formed by selective sintering of the outer walls of one or more of the channels.

9. The faucet of claim 1 , wherein the spout portion of the faucet is in the shape of a parabolic arc.

10. The faucet of claim 1 , wherein each of the plurality of water channels is configured to output water into a single combined water stream.

11. The faucet of claim 1 , wherein the plurality of water channels are collectively formed as a unitary metal component.
