Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shower head.
[0002]
[Background Art and Problems to be Solved by the Invention]
For example, by operating the switching means provided in the water outlet main body of the shower head used for the hair washing shower, water can be discharged in the state of direct discharge through the water passage formed in the central part of the water outlet main body, or the water outlet main body The water is discharged in the form of water (shower) through a water flow passage formed around the center of the water. However, when plating is performed on the water outlet body to improve the appearance, the inner surface of the water outlet body Is also immersed in the plating solution, causing a problem that Ni or the like is likely to elute into the water flow passage. As a countermeasure against this, masking is applied to the inner surface of the spout main body, but there is a problem that the defect rate is high and the cost is high.

Reference numeral 10 denotes an operation member linked to the movable disk 9b. By operating the operation member 10, the operation for switching between the water stop state and the water discharge state, the temperature adjustment of the hot and cold water mixture, and the flow rate adjustment of the hot and cold water mixture and water are performed. Is called. The body 4a is made of metal and has an external shape formed by cutting off both ends of the ellipsoid in the major axis direction. The holder 6 is made of metal, and is provided in a mixed water or water supply hole 4b formed in the body 4a so that it can be sealed by a locking means such as a locking pin 6a.
[0008]
The characteristic configuration of the present invention will be described below.
[0009]
1 to 11, the shower head 5 includes a resin cover body 14 having an upper opening 12 and a lower opening 13, an inlet portion 15 communicating with a supply flow path i from the faucet body 4, and the inlet portion 15. A resin-made spout main body 17 having a downward spout 16 that is connected to the downstream side of the water, and a switch composed of a plurality of resin-made members provided for switching between two sprinkling and sprinkling states Means. In this embodiment, the water outlet body 17 is detachably mounted in the cover body 14 via the lower opening 13, and forms a water flow path j between the inlet portion 15 and the water outlet portion 16. The inlet portion 15 has an inner screw 15b on the inner peripheral surface.
[0010]
Further, the cover body 14 has a substantially bell-shaped vertical cross section, and the entire surface including the outer surface and the inner surface is plated by being immersed in a plating solution.
[0011]
The cover body 14 has four engaging projections 18 arranged on the circumference on the lower inner surface, while the water discharge main body 17 has an engagement groove 19 that engages with each engagement protrusion 18 in the water discharge port portion 16. On the outer peripheral surface.
[0012]
The shower head 5 is inserted into the upper opening 12 in a state where the downstream end 7 c of the flexible tube 7 is connected, and is connected to a spout body 17 attached in the cover body 14. 20 The shower receiver 20 has a cylindrical shape, and has a small-diameter outer screw portion 21 that is screwed to the inner screw 15b on the downstream side, and an annular contact surface that contacts the annular end surface 15a of the inlet portion 15 on the upstream side. A large-diameter portion 22 having 22a is formed, and the entire surface including the outer surface and the inner surface is plated by being immersed in a plating solution. Further, the outer threaded portion 21 has an adapter 23 for fixing a flexible tube, which is fixed in a state where the downstream end 7 c of the flexible tube 7 is inserted, on the inner peripheral surface via a U packing 24. The large diameter portion 22 has a serration 25 on the inner peripheral surface.
[0013]
26 is a cylindrical resin engagement member that has a serration 25 meshing with the serration 25 on the outer peripheral surface and is fitted into the holder 6 via a ring body 27. The outer surface and the inner surface are immersed in a plating solution. The entire surface including is plated.
[0014]
The switching means has a resin-made switching handle 36 that switches between two water discharge states and direct water discharge by a turning operation, and two communication holes 32 that communicate with the water flow path j, and through an O-ring 34. A resin valve seat member 33 having a circular shape in plan view, which is fixedly installed on the uppermost stream side of the water discharge port portion 16 of the water discharge port main body 17, and a direct water discharge hole 37 which can be aligned with the two communication holes 32 are provided in the center portion. And a resin valve body 40 that has a large number of shower holes 41 for watering around the central portion and rotates in conjunction with the rotation operation of the switching handle 36, and the holes of the valve body 40. And a plurality of rectifying plates 43 provided around the mesh with a resin material.
[0015]
Further, a protruding portion 40a for forming two direct water discharge holes 37 is integrally formed on the upstream surface m of the valve body 40 so as to slide on the downstream surface 33a of the valve seat member 33. And a seal packing 44 that covers the periphery of the protruding portion 40a. Then, the valve body 40 is rotated by the switching handle 36 as shown in FIG. 11 so that the hole 37 is aligned with the communication hole 32, so that the water is directly discharged. On the other hand, as shown in FIGS. When the valve body 40 is rotated, the hole 37 is closed by the downstream surface 33a of the valve seat member 33 so as to be able to be sealed, and the communication hole 32 communicates with the shower hole 41 to form a water spray.
[0016]
Thus, the cover body 14 visible from the outside is plated, and the shower head 5 is configured so as not to perform plating on the water outlet body 17 and the switching means constituting the water flow path j. In addition, it is possible to solve the problem that Ni or the like easily elutes into the water passage.
[0017]
In addition, since it was set as the structure which connected the shower receptacle 20 to the spout main body 17 via the upper opening 12, the interphase line L formed between the cover body 14 and the shower receptacle 20 can be made clear, and an external appearance looks good.
[0018]
FIG. 12 shows a configuration in which the cylindrical holder 6 is bent in a substantially L shape, and the body 4a is placed in a horizontal state so that the hot water mixed water or water supply hole 4b faces upward, and the cylindrical is placed in the supply hole 4b. The other embodiment of this invention provided in the hot-and-water mixing faucet 1 'formed by connecting the cylindrical holder 6 is shown.
[0019]
【The invention's effect】
As described above in detail, the present invention has an effect of providing a shower head having a water flow path in which Ni or the like does not elute because the water flow path is not plated.
