A faucet 10 according to the present invention has a single cartridge 14 mounted in a faucet body 12 and has a single operating handle. It changes the flow rate of water or hot water discharged from the hot water discharge part.

The single cartridge 14 is water and hot water switching/flow rate adjusting means for switching between cold and hot water and for adjusting the flow rate of cold and hot water through the water discharge pipe (mouth).
That is, the single cartridge 14 can be operated by rotating the operating lever 16 for operating the movable disk 40 in the first direction and in the second direction opposite to the first direction, thereby supplying hot and cold water. The hot water inflow hole 22 and the water inflow hole 24 are provided within the same angular range with respect to the center line C of the fixed disk 20 in the front-rear direction, and the center line C When the operation lever 16 is positioned on the , the water is stopped.

The single cartridge 14 includes a fixed disk 20 provided with a hot water inlet 22 and a water inlet 24, and a hot water and water inlet hole slidably disposed on the fixed disk 20 and flowing in from the hot water inlet 22.

The hot water inlet 22 and the water inlet 24 of the fixed disk 20 are formed as elongated kidney-shaped holes, and are formed symmetrically with respect to the longitudinal center line C of the fixed disk 20 .

When the movable disk 40 rotates in the first direction on a plane perpendicular to a straight line extending in the rotation axis direction of the movable disk 40, water flows into the hot water communication passage 42 from the water inlet hole 24 of the fixed disk 20, Also, when the fixed disk 20 is rotated in the second direction, the hot water flows into the hot water communication passage 42 from the hot water inlet 22 of the fixed disk 20. A discharge rate is determined.

The single cartridge 14 allows the operation lever 16 to be moved from the central position in the horizontal direction to
By rotating in the left direction, which is the first direction, and in the right direction, which is the second direction, the hot water inlet hole 22 or the water inlet hole 24 of the fixed disk 20 and the hot water communication passage 42 of the movable disk 40 are connected, It is configured to discharge hot or cold water.

The movable disk 40 rotates and slides relative to the stationary disk 20 on a plane perpendicular to a straight line extending in the direction of the rotation axis P of the movable disk, and rotates in the first direction. Hot water flows into the hot water communication passage 42 from the fixed disk 24, and when the fixed disk 20 rotates in the second direction, hot water flows into the hot water communication passage 42 from the hot water inlet 22 of the fixed disk 20. and the angle of rotation in the second direction determines the amount of spouted water.

The faucet 10 is provided with a click mechanism that indicates that the operation lever 16 is at the water stop position.

The basic principle of operation of the single cartridge 14 according to the present invention is that by rotating the operating lever 16 about the rotating shaft P, the plug rod 150 constituting the rotating shaft connected to the operating lever 16 is rotated.
