It is installed in. The faucet 1 includes a hot-water supply pipe and a hot-water mixing faucet body (body) 4 that appropriately mixes hot water and water flowing from the water supply pipe and supplies hot-water mixed water to a supply pipe 3 that is a flexible hose. A resin-made shower head 5 that switches between a hot / cold mixed water or water supplied from the main body 4 to a state of direct discharge or sprinkling and discharges water, and the shower head 5 and the supply pipe 3 are connected via a joint member 8. In addition, it has a flexible tube 7 which is pulled out from the cylindrical holder 6 of the faucet body 4 when used. The flexible tube 7 is a spiral hose formed by fixing a resin member 7b to an inner surface of a stainless steel strip 7a having a spiral shape, and forms a supply flow path i from the faucet main body 4.
[0007]
The cylindrical holder 6 is for holding the flexible tube 7 so as to be able to be pulled out. The cylindrical holder 6 is made of metal, and is connected to an opening 11 for inserting a flexible tube formed on the front surface of the faucet body 4 in a state facing obliquely upward. The shape of the inner wall surface W of the opening 11 for inserting the flexible tube is appropriately set, but is preferably a shape having a curved surface. As shown in FIG. The end K preferably has a substantially elliptical shape that is vertically long in a front view.
[0008]
Reference numeral 9 denotes a valve mechanism provided inside the faucet main body 4 and includes a ceramic fixed disk 9a and a ceramic movable disk 9b slidably mounted on the upper surface of the fixed disk 9a. Reference numeral 10 denotes an operation member linked to the movable disk 9b. By operating the operation member 10, the operation of switching between the water stoppage state and the water discharge state, the temperature adjustment of the hot / cold mixed water, and the flow rate adjustment of the hot / cold mixed water and water are performed. Is The faucet main body 4 is made of metal and has an external shape in which both ends in the direction of the major axis A of the ellipsoid are cut off.
[0009]
Hereinafter, the characteristic configuration will be described.
Numeral 12 denotes a drain guide made of, for example, resin and having a shape fitted inside the upstream end M of the cylindrical holder 6. The drain guide 12 has a ring shape and has a communication hole 13 communicating with the flexible tube insertion opening 11 provided in the faucet main body 4, and is fitted inside the upstream end M of the cylindrical holder 6. In this state, it is connected to the opening 11 for inserting the flexible tube together with the cylindrical holder 6 by connecting means described later. The upstream end portion M into which the drainage guide 12 is fitted (fitted) includes an upper portion M ″ and a lower portion M ′.
[0010]
The downstream opening 6a of the cylindrical holder 6 is circular in a front view, but the upstream opening 6b of the cylindrical holder 6 has a shape capable of being fitted in the opening 11 for inserting the flexible tube. . Further, the cylindrical holder 6 has a plurality of screw insertion holes 14, 15, 16 along the end face L of the upstream end portion M (see FIG. 5A) in the upper portion M ''. The cylindrical holder 6 has a size such that the screw insertion holes 14, 15, 16 can be seen from the lower side immediately downstream of the lower part M ′ of the upstream end M internally fitted in the cylindrical holder 6. It has an opening 20. That is, the lower opening 20 is located immediately below the region where the screw insertion holes 14, 15, 16 are formed.
[0011]
On the other hand, when the upstream end portion M of the cylindrical holder 6 is fitted into the opening 11 for inserting the flexible tube, the flexible tube insertion opening 14, 15 and 16 are respectively connected to the screw insertion holes 14, 15 and 16. The opening 11 has screw holes 14 ′, 15 ′ and 16 ′ formed by drilling the upper part W ₁ of the inner wall surface W diagonally upward toward the back side of the faucet body 4, and screw insertion holes 14, 15 and 16. At a position corresponding to.
[0012]
When the drain guide 12 is fitted into the upstream end M of the cylindrical holder 6, the drain guide 12 is connected to the screw insertion holes 14, 15 and 16, respectively. At positions corresponding to 16, screw insertion holes 14 ″, 15 ″, and 16 ″ are provided.
[0013]
The reference numeral 19a denotes a state in which the drainage guide 12 is fitted in the upstream end M of the tubular holder 6, and the tubular holder 6 is fitted in the opening 11 for inserting the flexible tube. 20 through a screw insertion hole 15 ″ of the drainage guide 12 and the screw insertion hole 15 of the cylindrical holder 6 to a screw hole 15 ′ of the opening 11 for inserting the flexible tube. is there. Similarly, as shown in FIG. 3, reference numeral 19b denotes a fastening screw for fixing the holder to the screw hole 16 'of the opening 11 for inserting the flexible tube, and 19c denotes an opening 11 for inserting the flexible tube. This is a fastening screw for fixing the holder to the screw hole 14 '.
[0014]
The connecting means for connecting the drainage guide 12 together with the cylindrical holder 6 to the opening 11 for inserting the flexible pipe with the drainage guide 12 being fitted inside the upstream end M of the cylindrical holder 6 includes: Screw insertion holes 14 ", 15" and 16 ", screw insertion holes 14, 15 and 16, screw holes 14 ', 15' and 16 ', lower opening 20, and fastening screw 19c for fixing the holder. 19a and 19b.
[0015]
Next, a rattling preventing means for preventing rattling of the cylindrical holder 6 will be described.
[0016]
The opening 11 for inserting the flexible tube has a plurality of screw holes 17 and 18 on the front side of the faucet body 4. That is, the opening 11 of the flexible tube for insertion is in the vicinity of the opening end K, made through the faucet body 4 to the lower W ₂ in the inner wall W from the outer wall surface E immediately below the opening end K It has a plurality of screw holes 17,18.
[0017]
The screws 21 and 22 screwed into the screw holes 17 and 18, respectively, are tightened until the respective tips 21a and 22a press the lower portion M 'of the upstream end M of the cylindrical holder 6 from outside. As described above, the cylindrical holder 6 is rattled only by connecting the upper surface side of the cylindrical holder 6 to the opening 11 for inserting the flexible tube, but the lower surface side of the cylindrical holder 6 is connected to the tips of the screws 21 and 22. Since the cylinder holder 6 is pressed against each other at 21a and 22a, it is possible to prevent the cylindrical holder 6 from rattling. Points R and S in FIG. 5D indicate the press-contact positions of the tips 21a and 22a of the screws 21 and 22, respectively.
[0018]
Next, a description will be given of a means for sealing the mixed water or water traveling along the inner peripheral surface of the cylindrical holder 6 and reaching the opening for inserting the flexible tube.
[0019]
The drain guide 12 has an annular groove 31 on the outer peripheral surface into which the O-ring 30 is fitted. Since the O-ring 30 presses the inner wall surface W of the opening portion 11 for inserting the flexible tube, the hot and cold water which travels along the inner peripheral surface of the cylindrical holder 6 and reaches the opening portion for inserting the flexible tube. Mixed water or water can be sealed.
[0020]
Therefore, according to the present invention, as shown in FIG. 7, the faucet main body 4 can be easily provided with a cylindrical holder 6 ′ having a longer shape than the cylindrical holder 6 used in the above embodiment or a cylindrical holder having a different shape. It has the advantage of being replaceable. In FIG. 7, the same components as those shown in FIGS. 1 to 6 are the same or equivalent.
