Abstract

A mixer faucet includes a faucet fixed to a fixing board in a wall and a temperature control valve is connected to the temperature control valve seat. Two check valves are connected to the check valve seats of the cold and hot water paths of the faucet. An indication board is connected to the faucet and seals an installation hole in the wall. The indication board has two access holes which are located corresponding to the check valves. The check valve seats each have a reception recess and the two respective reception recesses are oriented inclinedly and outward. A water inlet is defined between each of the reception recesses and an installation recess of each of the temperature control valve seats. The faucet can be made by way of forging and machined after being forged. The maintenance to the check valves is convenient.

Claims

1. A mixer faucet comprising:

a faucet fixed to a fixing board in a wall and having a cold water path, a hot water path, two mixing paths and a temperature control valve seat, the cold and hot water paths each having a check valve seat connected thereto and two check valves are connected to the check valve seats, a temperature control valve connected to the temperature control valve seat, an indication board connected to the faucet and sealing an installation hole in the wall, the indication board having two access holes which are located corresponding to the check valves, a central hole defined through the indication board and the temperature control valve extending through the central hole, wherein

the check valve seats each have a reception recess, the two respective reception recesses are oriented inclinedly and outward, a water inlet is defined between each of the reception recesses and an installation recess of each of the temperature control valve seats, each of the water inlets includes a vertical path and an inclined path, the vertical path extends downward from an inner end of the installation recess of the temperature control valve seats, the inclined path extends inclinedly and downward from an inside of the installation recess of the check valve seat and communicates with the vertical path.

2. The mixer faucet as claimed in claim 1, wherein the temperature control valve seats of the faucet includes a positioning groove defined in an outside thereof and a seal ring is engaged with the positioning groove, a sleeve is threadedly mounted to the temperature control valve seats so as to press the temperature control valve on the temperature control valve seats, an inside of the sleeve is in contact with the seal ring.

3. The mixer faucet as claimed in claim 1, wherein the faucet includes at least two pads on an underside thereof so as to contact the surface of the fixing board, the at least two pads have a height which defines an operation room between the connection portions of the cold and hot water paths, the connection portions of the mixing paths and the surface of the fixing board.

4. The mixer faucet as claimed in claim 1, wherein an installation flange is located between outside of the faucet and respective tops of the temperature control valve seats, the installation flange includes multiple first fixing holes, multiple support tubes extend from an inner end of the indication board and each support tube has a passage defined therein, multiple bolts each extend through the passage of the support tube and are connected with the first fixing holes to fix the indication board to the installation flange.

5. The mixer faucet as claimed in claim 4, wherein the installation flange includes multiple second fixing holes and bolts extend through the second fixing holes and are fixed to the fixing board to fix the faucet to the fixing board.
