Metering valve 30 for discharging the mixed water mixed with cold and hot water to the discharge tube 50 and the hose 17 of the shower side is installed in the discharge tube 50, the normal opening and closing valve 40 is It is installed.

The faucet body 10 has a cold-hot water chamber 12a, 12b communicating with both cold water and hot water inflow holes 11a, 11b, respectively, and is formed at an intersection of the cold-hot water chambers 12a, 12b. The mixing valve installation space 13 and the fixed-quantity valve installation space 14 are formed, and the bottom of the mixing valve installation space 13 has a cold-hot water inlet hole communicating with the cold-hot water chambers 12a and 12b ( 13a and 13b are formed, and the mixed water inlet hole 13c communicating with the metered valve installation space 14 is formed, and a setting groove 13d for setting the mixing valve 20 is formed.

In addition, the mixed water outlet hole 14c communicating with the discharge port 15 is formed on the wall surface of the metering valve installation space 14, and a valve seat 14b is formed to seat the valve 31d of the metering valve 30. In the chamber 12b on one side of the faucet body 10, a shower discharge passage 16 is formed in communication with the valve seat 14b of the metered valve installation space 14. In the shower discharge passage 16, the first chamber 16a, the connection hole 16b, the second chamber 16c, and the discharge hole 16d are in line with each other. The shower (not shown) at the end of the hose 17 connected to the shower discharge passage 16 has a mixing valve 20 when the metering valve 30 is pressed while the on / off valve 40 of the discharge tube 50 is locked. The mixed water flowing out from the shower is discharged to the shower through the shower discharge passage 16.

The mixing valve 20 has a hollow two-stage tubular housing 21, a movable valve member 22 installed and rotated in the tubular housing 21, and a lower surface and airtightness of the movable valve member 22. It consists of a fixed valve plate 23 and a disk-shaped base member 24 is mounted on the lower end of the tubular housing (21).

The disc-shaped base member 24 is formed with a first cold water port 24a and a first hot water port 24b connected to the cold-hot water chambers 12a and 12b of the faucet body 10, respectively. The first outflow port 24c through which the mixed water mixture is discharged is formed. In addition, a lower surface of the disc-shaped base member 24 is provided with a setting protrusion 24d for setting the bottom of the mixing valve installation space 13 of the faucet body 10.

A fixed valve plate 23 is mounted on the upper surface of the disc-shaped base member 24 at the bottom of the tubular housing 21, and the first cold water port 24a and the first of the disc-shaped base member 24 are mounted. The second cold water port 23a, the second hot water port 23b, and the second outlet port 23c are formed at positions communicating with the hot water port 24b and the first outlet port 24c.

The tubular housing 21 is provided coaxially with the movable valve member 22 so as to be rotatable in a state where airtightness is maintained with the inner surface of the tubular housing 21 as well as the fixed valve plate 23. A port connecting groove 22b is formed on the lower surface of the valve member 22a, which is in contact with the plate 23, and the lever member 22c extends through the tubular housing 21 upwardly on the upper surface of the valve member 22a. It is.

The port connecting groove 22b of the movable valve member 22 opens the second hot water port 23b to the maximum when the movable valve member 22 is turned to the hot water side as much as possible. It should be formed in a key shape that is connected (communicated) to a very small part. The reason for this is to prevent burns when only hot water is supplied from a boiler or the like when the movable valve member 22 is rotated to the hot water side as much as possible.

The mixing valve 20 is seated in the mixing valve installation space 13 of the faucet body 10 and the upper end of the tubular housing 21 of the mixing valve 20 by a tightening nut 25 fastened to the upper inner surface thereof. It is pressed and fixed.

The metering valve 30 is composed of a piston 31 which is raised and lowered in the metering valve installation space 14 having an orifice groove 14a on the inner surface thereof, and an actuating rod 32 that lowers the piston 31.

The piston 31 is formed of a hollow cap-shaped cross section, but the first packing 31a for airtightness with the inner surface of the metering valve installation space 14 is installed at the upper and lower portions of the outer surface thereof, and the spring 31b is disposed at the lower end thereof. A supporting cap 31c is fastened, and a valve 31d that blocks the valve seat 14b in the metered valve installation space 14 is fastened to the upper end thereof.

The actuating rod 32 is installed to protrude upward in a state that is elastically supported by the spring 31b in the piston 31, and a second packing 32a for airtightness with the piston 31 is provided at the lower end thereof. It is installed.

The actuating rod 32 is a faucet to prevent leakage by the bush 33 and the third packing 34 in a state in which the piston 31 is seated and installed in the fixed amount valve installation space 14 inside the faucet body 10. It extends through the body 10, the operating button 35 is mounted on the operating rod 32 and the operating rod 32 is returned to its original position between the bush 33 and the operating button 35. Spring 36 for elasticity is installed elastically.

The discharge pipe 50 is rotatably installed in the discharge port 15 of the faucet body 10 and the on-off valve 40 of the discharge pipe 50 is the valve shaft 42 is rotated together with the handle 41 It is provided to be elevated in accordance with the structure is provided in close contact with the valve seat 51 of the discharge pipe 50 when the valve 42a at the lower end of the valve shaft 42 is inserted.

Although illustrated and described as forming the orifice groove 14a on the inner surface of the metering valve installation space 14, the same effect can be obtained even by providing an orifice hole in the piston 31 of the metering valve 30.

The quantitative discharging and continuous discharging faucet configured as described above first locks the on / off valve 40 installed in the discharge pipe 50 and then the cold and hot water inflow holes 11a and 11b of the faucet body 10 and the cold-hot water chamber. The movable valve member in a state in which cold water and hot water are supplied from the first cold water port 24a and the first hot water port 24b of the disc-shaped base member 24 constituting the mixing valve 20 through 12a and 12b. The lever member 22c of 22 is rotated to the cold water or hot water side.

For example, as the lever member 22c of the movable valve member 22 is turned to the cold water side, the cross-sectional area communicating with the second cold water port 23a is increased, and conversely, the cross-sectional area communicating with the second hot water port 23b is small. As a result, increasingly cold mixed water flows out through the first outlet port 24c. When the lever member 22c of the movable valve member 22 is turned to the cold water side at the maximum, only the cold water flows out because the second hot water port 23b is completely blocked.

As the lever member 22c of the movable valve member 22 is turned to the hot water side, the cross-sectional area communicating with the second cold water port 23a and the second hot water port 23b is only made in the opposite direction as when turned to the cold water side. It can be seen that the mixed water flows out. When the lever member 22c of the movable valve member 22 is turned to the hot water side, the second hot water port 23b is completely opened and the second cold water port 23a is kept slightly open. The reason for this is that some hot water is added to the hot hot water supplied from the boiler or the like, even if the movable valve member 22 is turned completely to the hot water side, only hot hot water is not supplied to prevent burns.

The mixed water flowing out through the first outlet port 24c of the mixing valve 20 is a mixed water inlet hole 13c, a fixed volume valve installation space 14, an outlet 15, and an opening / closing valve of the discharge tube 50. It is in the state supplied up to (40). That is, the cold-hot water introduced into the cold water and hot water inflow holes 11a and 11b of the faucet body 10 is mixed from the cold-hot water chambers 12a and 12b to the mixing valve 20, the discharge port 15, and the discharge pipe 50. It is a state which is always supplied until the on-off valve 40 of the). At this time, the valve seat 14b is in close contact with the valve 31d on the upper end of the piston 31 provided in the metered valve installation space 14.

In such a state, when the handle 41 of the on-off valve 40 installed in the discharge pipe 50 is turned to open the on-off valve 40, the discharge is continuously performed, so that a large amount of water may be received in a bathtub or the like.

On the other hand, when the opening and closing valve 40 of the discharge pipe 50 is closed, pressing the operation button 35 fastened to the end of the operation rod 32c of the metering valve 30, the spring 31b in the piston 31 is After being pressed, the piston 31 starts to retreat and the piston 31 is retracted so that the valve 31d of the piston 31 is opened to be spaced apart from the valve seat 14b so that the mixed mixture passes through the mixing valve 20. Water is discharged from the metered valve installation space 14 to the shower via the valve seat 14b and the shower outlet flow path 16.

As such, when the force (external force) applied to the operation button 35 is removed while the mixed water is discharged, due to the elastic force of the spring 31c inside the piston 31 and the spring 36 on one side of the operating rod 32, The force to push the operating rod 32 back to its original position is applied, but the negative pressure formed in the metering valve installation space 14 gradually rises as air or cold / hot water flows in and is removed through the orifice groove 14a on the inner surface thereof. do. At this time, the piston 31 installed at the lower end of the operating rod 32 is also returned to the original position.

While the piston 31 at the lower end of the operating rod 32 is thus returned, the mixed water is discharged for a predetermined time and the piston 31 is completely returned to its original position so that the valve 31c of the piston 31 blocks the valve seat 14b. Therefore, the discharge of the mixed water is blocked.

The discharge time of the mixed water is not only the size of the orifice groove 14a formed on the inner surface of the metering valve installation space 14 but also the spring 36c provided on one side of the spring 31c and the operating rod 32 of the piston 31. It is determined by the elastic force.

In other words, when the orifice groove 14a is large or the elastic force of the springs 31b and 36 is large, the supply of air or water is easy, so that the discharge time is short, and the orifice groove 14a is small or the elastic force of the springs 31b and 36 is reduced. The smaller it is, the slower the air or water supply, and the longer the discharge time.

Therefore, it takes about 8 seconds to simply wash the face in the public toilet, and about 25-30 seconds when washing the face and shower in the shower room of the lodging facility. You can control as much as you can.

As described above, the quantitative discharging and continuous discharging faucet according to the present invention opens the on / off valve of the discharge tube so that the mixed water mixed by the mixing valve is continuously discharged through the periphery of the metering valve and the on / off valve of the discharge tube. A large amount of water can be received in the bathtub, and when the operation button of the metering valve is pressed and released while the opening / closing valve of the discharge tube is closed, there is a unique effect that only the metering is discharged to the shower side through the shower discharge channel of the faucet body.
