The mixing plug main body 2 that appropriately mixes hot water and water flowing in from the mixing water and supplies the mixed water M to the mixed water supply pipe 2a, and the hair washing shower that discharges the mixed water M supplied from the mixing plug main body 2 (an example of a shower head) )) 3, and a flexible tube 4 for connecting the hair washing shower 3 and mixed water supply pipe 2a.
[0006]
Reference numerals 2b and 2c are supply pipes connected to the pipes B and W, respectively. Reference numeral 2d is an operation lever for adjusting the mixing ratio of hot water supplied to the mixed water supply pipe 2a and the amount of discharged water including water stoppage.
[0007]
The shampoo shower 3 is supported by a shower holder 3a through which the flexible tube 4 can be inserted, and can be pulled out from the tip 3b of the shower holder 3a. The flexible tube 4 drawn out from the lower end 3c of the shower holder 3a is connected so as to communicate with the mixed water supply tube 2a while passing through the guide 5. Reference numeral 6 denotes a weight provided in the middle of the flexible tube 4.
[0008]
Hereinafter, the hair-washing shower 3 will be described.
In FIG. 1 to FIG. 5, reference numeral 11 denotes a synthetic resin spout body, which is provided with a water supply path 13 for connection to the flexible tube 4 on the lateral side.
[0009]
Reference numeral 14 denotes a synthetic resin water discharge cap that is screwed to the lower side of the water discharge main body 11. The water discharge cap 16 is formed around the direct water discharge flow channel 15 at the center and is directly discharged. The water outlet 15 of the water channel 15 and the water spray channel 16 is provided with, for example, a plurality of water spray plates 17, 17 '.
[0010]
Reference numeral 18 denotes a synthetic resin diversion member built in the spout main body 1, and includes a first chamber 9 communicating with the direct discharge channel 15 and a second chamber 10 communicating with the water spray channel 16. .
[0011]
21 is a valve mechanism for switching between the water stop flow path S, the direct water discharge flow path 15 and the water spray flow path 16, as shown in FIGS. 3 (B), 4 (B) and 5 (B). Valve seats 22 and 23 having valve seat flow paths a and b communicating with the water supply passage 13 are provided on the upper surface plate 18a of the flow dividing member 18 so as to correspond to the first and second chambers 9 and 10, respectively. The bottomed valve seats 19 and 20 are provided. Further, a synthetic resin valve body holding member 24 is provided in a space on the upper side of the spout main body 11 so as to be rotatable around an axial axis in the vertical direction. Then, two metal ball valve bodies (water stop valve bodies) 25 arranged so that the valve seat flow paths a and b are alternatively opened or both are closed are closed by springs 26. The rotating operation tool (button) 27 is connected to the valve body holding member 24 and the operation tool 27 is exposed to the lateral side portion of the spout main body 11. The rotating shaft portion of the operating tool 27 includes a pin 29 erected on the upper surface plate 18 a of the flow dividing member 18, a hole 30 with a groove 30 a formed in the rotating operating tool 27, and a fitting engagement with the hole 30. And a spline shaft 31 formed on the valve body holding member 24.
[0012]
According to the above configuration, as shown in FIG. 3, the valve seat flow paths a and b can be opened by alternatively opening the valve seat flow paths a and b by the ball valve body 25 or by closing both flow paths. A water stop state in which both are closed and a water stop passage S is formed, and as shown in FIG. 4, a direct discharge water discharge state in which the valve seat passage b is opened and the water supply passage 13 is communicated with the direct discharge passage 15. As shown in FIG. 5, it is possible to reliably switch and reveal the water sprinkling state in which the water supply channel 13 is communicated with the water spray channel 16 using the valve seat channel a. In addition, 38 is an opening that forms the valve seat flow path a, and 39 is an opening that forms the valve seat flow path b.
[0013]
Further, as shown in FIG. 6, the applicant of the present application, for example, at the most upstream end of the flexible tube 4, that is, the mixed water supply tube 2a side of the flexible tube 4, is disclosed in Japanese Patent Application No. 10-173603 (Japanese Patent Laid-Open No. 2000-173). No. 9243) is provided with a pressure reducing valve 33 as proposed. When the hair is washed by the pressure reducing valve 33, the operation lever 2d of the mixing plug main body 2 is sprinkled and the water is sprayed by operating the turning operation tool 27 of the hair washing shower 3. When the operation tool 27 is operated to stop water, when the pressure of the flexible tube 4 becomes higher than a predetermined pressure, the valve body 40 comes into contact with the seal packing 41 which is a valve seat to close the valve, thereby adjusting and stabilizing the water discharge amount. Can be achieved.
[0014]
In addition, a joint 42 of a simple attachment / detachment mechanism as proposed by the present applicant in Japanese Patent Application No. 9-298771 (Japanese Patent Laid-Open No. 11-81400), for example, is provided at the primary side inlet 43 of the pressure reducing valve 33. By adopting a simple attachment / detachment mechanism for connection to the joint 44 provided at the most downstream end of the mixed water supply pipe 2a, the mixed water supply pipe 2a and the flexible pipe 4 can be easily connected with one touch.
