Faucet
A faucet includes a spout body formed by joining an upper body and a lower body to one another. A one-piece spout tube is secured to the upper body. For example, only a cartridge seat and an aerator of the faucet are used to hold the spout tube in the upper body. Water supply hoses connected to the cartridge seat bring hot and/or cold water from a water supply source to a valve cartridge interfaced with the cartridge seat. The water flows from the water supply source, through the water supply hoses, the cartridge seat, the valve cartridge, and the spout tube, and out the spout body through the aerator. The valve cartridge allows a user to control a flow rate and/or temperature of the water delivered through the spout tube and out the spout body.
1. A faucet comprising:
an upper shell and a lower shell, the upper shell and the lower shell being operable to interface to form a spout body;
a cartridge seat;
a spout tube operable to be secured to the upper shell; and
an aerator operable to interface with the upper shell, said aerator including a threaded portion for interfacing with a complementary threaded portion formed in the upper shell,
wherein the spout tube is operable to interface with the cartridge seat so that the spout tube and the cartridge seat are in fluid communication,
wherein interfacing the spout tube with the cartridge seat is operable to secure the spout tube to the upper shell, and
wherein interfacing the aerator with the upper shell is operable to further secure the spout tube to the upper shell.
2. The faucet of claim 1 , wherein the cartridge seat is a one-piece body operable to be secured to the upper shell.
3. The faucet of claim 1 , wherein the cartridge seat is operable to interface with a valve cartridge so that the cartridge seat and the valve cartridge are in fluid communication.
4. The faucet of claim 3 , wherein the valve cartridge includes a first seal member,
wherein the cartridge seat includes a second seal member, and
wherein the second seal member is operable to prevent leakage of water in the event the first seal member fails.
5. The faucet of claim 1 , wherein an end of the spout tube friction fits into an opening in the cartridge seat.
6. The faucet of claim 5 , wherein the end of the spout tube includes a recess for receiving a seal member.
7. The faucet of claim 1 , wherein the spout tube is a one-piece body.
8. The faucet of claim 7 , wherein the spout tube is made entirely of plastic.
9. The faucet of claim 8 , wherein the spout tube is formed using a gas-assisted molding process.
10. The faucet of claim 1 , wherein the spout tube is operable to interface directly with the upper shell, and
wherein interfacing the spout tube with the upper shell further secures the spout tube to the upper shell.
11. The faucet of claim 7 , wherein the spout tube is a hollow body having a straight portion at a first end and an annular flange at a second end, and a generally curved portion extending between the first end and the second end.
12. The one-piece spout tube of claim 11 , wherein the straight portion of the hollow body is operable to interface with the cartridge seat of the faucet.
13. The one-piece spout tube of claim 12 , wherein the interface between the straight portion of the hollow body and the cartridge seat of the faucet is one of a friction fit and a snap fit.
14. The one-piece spout tube of claim 11 , wherein the annular flange of the hollow body is operable to interface with at least a portion of a housing of the faucet.
15. The one-piece spout tube of claim 14 , wherein the interface between the annular flange of the hollow body and the housing of the faucet is one of a friction fit and a snap fit.
