DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hose storage type faucet in which a flexible hose connected to a water discharge head is inserted into a hose storage tube.

[0002]

2. Description of the Related Art FIG. 9 shows an example of a shower faucet which is widely used as a faucet for a kitchen or a faucet for washing a shampoo, as an example of a hose faucet of this kind. In the figure, reference numeral 200 denotes a counter as a mounting base, and the faucet main body 202 and the water discharging section 2
04 is attached at a position separated from the other.

[0003] A water and hot water supply pipe 2 is provided in a faucet body 202.
Reference numeral 06 is connected, and water and hot water are supplied to the faucet main body 202 through the supply pipes 206. Faucet body 20
2 mixes the supplied water and hot water at a predetermined ratio by operating the handle 208, and flows out the mixed water to the outside through the outflow pipe 210.

The water discharge section 204 has a water discharge head (shower head) 212 and a curved hose storage tube 216 for storing a flexible hose 214 connected to the water discharge head 212. The water discharge head 212 has a water discharge port 218 on the lower surface, and further has a switching operation unit 220 on the front surface for switching the water discharge from the water discharge port 218 from shower water discharge to rectified water discharge or vice versa.
14 together with the hose storage tube 216. Reference numeral 222 denotes a slide tube which moves up and down together with the shower head 212 and the hose storage tube 216, and is slidably inserted into a guide tube 224 having an external thread on the outer peripheral surface.

In the shower faucet of this example, the water discharge head 2
When the hose 12 is pulled out and used, a tubular hose guide for inserting the hose 214 therein and guiding the sliding thereof is provided.
It is attached to the tip of the hose storage tube 216.

[0006]

In this type of faucet, in order to drain water adhering to the outer surface of the hose, a tubular drainer is mounted on the outer surface of the hose in a fitted state. I have. In this case, the inner diameter of the hose guide should be close to the outer diameter of the hose, that is, the gap between the outer surface of the hose and the inner surface of the hose guide should be as small as possible,
It is conceivable that the hose guide performs draining, that is, the hose guide also serves as a draining member.

However, in this case, if an end fitting having a diameter larger than that of the hose is once caulked and fixed to the end of the hose, then the hose guide cannot be fitted and attached to the hose. Is generated.

Usually, an end fitting having a larger diameter than the hose is caulked and fixed to the end of the hose for connection with a mating part, but if the end fitting is fixed in this way, the hose The end fitting cannot pass through the guide, and the hose guide cannot be attached to the hose later.

Therefore, in this case, after the hose guide is fitted to the hose in advance and attached, the end fitting must be caulked to the end of the hose, and the hose, the end fitting, and the hose guide must be fixed. It must be treated as an integral hose assembly (hose assembly).

In other words, there is a restriction that a hose assembly including a hose, end fittings, and a hose guide must be prepared beforehand when the faucet is attached, and the faucet must be assembled using the hose assembly. This causes a problem that the workability at the time of installing the faucet is deteriorated. In addition, even when it becomes necessary to replace the hose guide with another one, there arises a problem that parts interchangeability is poor. On the other hand, there has also been proposed a faucet in which a draining member is provided separately from the hose guide, and these are attached to the end of the hose storage tube.

FIGS. 10 to 12 show an example (Japanese Patent Application Laid-Open No. H10-147963). The illustrated example is the faucet body 2
The hose 214 connected to the water discharge head 212 is housed therein by extending a hose storage tube 216 from the tube 02. In this example, the hose guide has a cylindrical shape.

As shown in FIG. 12, the hose guide 226 is provided with an elastic piece 228, and the elastic piece 228 is provided with a locking claw 230. The hose guide 226 is elastically locked in the locking hole 232 provided on the pipe 216 side.
Are attached and fixed to the hose storage tube 216.

In FIGS. 10 and 11, reference numeral 240 denotes a draining member which is separate from the hose guide 226 and has a donut shape. The draining member 240 is fitted to the hose 214 at a position adjacent to the hose guide 226 in the axial direction. Then, water adhering to the outer surface of the hose 214 is drained.

When the draining member 240 is provided separately from the hose guide 226 in this manner, the draining member 240
It is necessary to keep the inside diameter small so that draining can be performed properly.
After fitting the hose 40 to the hose 214 in advance, it is necessary to caulk an end fitting to the end of the hose 214.

When the inner diameter of the hose guide 226 is small (this is the case in the illustrated example), the hose guide 226 is also fitted to the hose 214 in advance before the end fitting is fixed by caulking. It is necessary to keep it. In this case, the hose assembly is a hose 214,
The draining member 240, the hose guide 226, and end fittings at both ends of the hose are assembled.

Therefore, even in this case, it is not possible to independently assemble the draining member 240 or the hose guide 226 for the first time at the stage of installing and installing the faucet.
There is a restriction that they cannot be assembled unless they are made into a hose assembly together with the hose 214 in advance, and the workability of installing the faucet is deteriorated in the same manner as described above, and the replacement of the draining member 240 or the hose guide 226 is required later. When it becomes necessary, there arises a problem that the parts cannot be easily replaced.

It is also conceivable that the draining member 240 is made of rubber and its inner surface is elastically adhered to the outer surface of the hose 214. In this case, after the end fitting is caulked and fixed to the end of the hose 214, the rubber draining member 240 is elastically expanded and deformed so that the end fitting can be passed over and attached to the hose 214 in a fitted state. Is also possible.

However, in this case, there is a problem that the assemblability of the draining member 240 is not sufficient, and furthermore, the sliding resistance when pulling out the hose 214 is increased, resulting in a poor operational feeling. Furthermore, when exchanging the components of the draining member 240, the exchangeability of the components is insufficient.
