Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a shower device in which a shower head is pulled out from a main body of a faucet so that the shower head can be used. The present invention relates to a hose drainage mechanism for preventing intrusion into a main body.

[Conventional technology]

2. Description of the Related Art For kitchen sinks, vanity tables, and the like, a shower device is used in which a shower head is fixed to a main body of a faucet, or a shower device in which a shower head is pulled out from a faucet so that dishes and hair can be washed.

FIG. 11 shows an example in which the faucet main body 1 is fixed to a counter 50 of a sink, and the faucet main body 1 is fixed to a sink 50.
The shower head 2 is attached so as to be used in a fixed state as shown in FIG. A water supply pipe 3a and a hot water supply pipe 3b from the outside are connected to the faucet body 1,
The built-in valve is operated by the single lever type handle 4. The downstream side of the valve and the shower head 2 are connected by a bendable hose 5.

The shower head 2 is detachably inserted into a holder 1a projecting obliquely upward from the faucet main body 1. When the shower head 2 is pulled out, the hose 5 is also attached to the holder 1a.
Move inside 1a and come out. Conversely, when returning the shower head 2 to the holder 1a, the hose 5 moves down inside the holder 1a and returns to the state shown in the figure.

When the shower head 2 is pulled out from the faucet main body 1 and used, the spouted water flows down to the hose 5 and easily flows into the faucet main body 1 through the holder 1a. When the shower head 2 is returned into the holder 1a after being used, the shower head 2 hangs below the counter 50 with water adhered to the surface of the hose 5. Therefore, water droplets adhering to the hose 5 fall under the counter 50 or drop into the cabinet.

[Problems to be solved by the invention]

In order to prevent such water droplets on the surface of the hose 5 from dripping into the faucet body 1 or into the cabinet, it has been conventionally provided with a draining mechanism in the holder 1a. For example, as described in Japanese Utility Model Laid-Open Publication No. 62-146864, a bush for draining water is provided by squeezing the peripheral surface of the hose 5 in the holder 1a.

In order to wipe off water adhering to the surface of the hose 5, a cylindrical bush or other appropriate members may be used. If these members are made of an elastic material, the degree of adhesion to the peripheral surface of the hose 5 is increased, so that drainage can be performed well.

However, if the hose 5 moves quickly when the hose 5 is stored, the drainage member made of an elastic material is also elastically deformed in the direction in which the hose 5 moves, and the adhesion to the hose 5 is reduced.
For this reason, there is a possibility that the hose 5 is stored without completely wiping the water drops, and the water drops may hang down in the cabinet.

In addition, if the hose 5 has a uniform outer diameter, there is no unevenness on its peripheral surface, so that the contact of the draining member does not hinder. However, if the bellows-shaped hose 5 is used so that the hose 5 can be easily bent, the outer diameter of the hose 5 changes to a large or small size, so that the hose 5 cannot follow the elastic deformation of the draining member.

As described above, in the case of using the elasticity of the draining member itself, it was not necessary to completely wipe off the water attached to the hose, and it was necessary to provide a water receiving tray or the like in the cabinet.

The problem to be solved in the present invention is to completely cut off water droplets attached to the hose and water flowing down from the shower head side to prevent ingress into the faucet side and the cabinet side.

[Means for solving the problem]

The present invention is a shower device comprising a holder capable of freely taking in and out a shower head and a hose connected thereto and holding the shower head, and a drainage mechanism incorporated in the holder, The mechanism includes a plurality of blocks which are movable in the radial direction of the hose and whose inner peripheral portion is a seal portion on the surface of the hose, and an elastic body which biases these blocks in the direction of the hose. And

[Action]

Since the plurality of blocks having a seal portion with respect to the peripheral surface of the hose are urged toward the hose by an elastic body, the peripheral surface of the hose is always sealed by receiving a mechanical action force due to elasticity. And even if the hose has irregularities,
Since the block moves in the radial direction according to the surface shape of the hose by the elastic body, it is possible to seal the hose surface while always maintaining a uniform sealing pressure. For this reason, even when the hose is moved, the seal pressure is maintained by the elastic force, so that the seal does not come off.Also, even if the hose is shaken violently, the block follows the movement of the hose, so that the water moves. Is eliminated. Therefore, both when the shower head is used and when the hose is stored in the holder, water is prevented from entering below the holder.

〔Example〕

FIG. 1 is a cutaway side view showing a main part of a water faucet body provided with a drainage mechanism of the present invention, FIG. 2 is a longitudinal sectional view of the main part, and FIG. 3 is a view taken along the line II of FIG. It is sectional drawing of a principal part.

As described with reference to FIG. 11, the faucet main body 1 is fixed to, for example, a counter of a sink, protrudes a holder 1a for attaching and detaching the shower head 2, and has an operating handle 4 at the upper end. A water supply pipe 3a and a hot water supply pipe 3b are connected to a valve mechanism for opening and closing the flow path by the handle 4, and water or mixed water is supplied to the shower head 2 by a hose 5 connected to the valve mechanism. The shower head 2 and the hose 5 are connected by a connector 2a, and connect respective internal flow paths. The hose 5 is a bellows tube having an uneven surface as shown in FIG. 1, and has a thickness such that it can be bent and bent.

A first guide 6 for receiving the connector 2a is provided in the holder 1a.
And a second guide 7 for guiding the hose 5 when it moves.
Are respectively incorporated. The first guide 6 has an inner diameter in which the base end of the shower head 2 and the connector 2a fit tightly, and has a drain hole 6a formed in the lower part. Also,
The second guide 7 is arranged at a distance from the proximal end of the first guide 6 and has an inner diameter larger than that of the hose 5. A similar drainage hole 7a is formed on the lower surface of the second guide 7, and a weir 7b is provided on the inner peripheral surface of the base end to strike the peripheral surface of the lower half of the hose 5. In addition, these drain holes 6a, 7
Holes 1b and 1c are formed in the lower surface of the holder 1a, respectively, corresponding to a.

Between the first guide 6 and the second guide 7, when the shower head 2 is used and stored together with the hose 5, a drainage ring 8 for wiping water on the peripheral surface of the hose 5 is incorporated. As shown in FIG. 3, the drain ring 8 includes four blocks 9, a coil spring 10 provided as an elastic body, and four packings 11 interposed therebetween.

FIG. 4 is a front view of the draining ring 8 as viewed from the tip end side of the holder 1a, FIG. 5 is an exploded perspective view of a connection structure of the draining ring 8 to the first guide 6, and FIG. 6 is viewed from another angle. FIG. 2 is an exploded perspective view of a first guide 6 and a block 9.

Each block 9 is formed of a synthetic resin as a material and is formed in an arc shape having a central angle of about 90 degrees, and its details are shown in FIG. As shown in FIG. 2 and FIG. 7, these blocks 9 have seal portions 9a having a triangular cross section in which a portion in contact with the hose 5 or the connector 2a is tapered. A U-shaped groove 9b is provided on the outer peripheral surface of the block 9, and a packing 11 having a U-shaped cross section is mounted in the groove 9b. A sliding projection 9c is provided on the surface of the block 9 facing the first guide 6.
To form a first guide 6 as shown in FIG.
A sliding groove 6b into which the sliding protrusion 9c fits is provided on the end face of the boss. These sliding projections 9c and sliding grooves 6b have a wedge-shaped sliding body structure like a dovetail groove, and the sliding direction is the radial direction of the circle formed by each block 9, that is, the radial direction of the hose 5 or the connector 2a. To match.

The packing 11 is assembled so as to straddle two adjacent blocks 9 as shown in FIG. Due to this built-in structure, as shown in FIG.
Is projected toward the center side, and a concave portion 9d into which the protrusion 11a fits is provided on the outer peripheral surface of the sliding protrusion 9c of the block 9. Since the sliding projection 9c is located substantially at the center of the block 9 in the circumferential direction as shown in FIG. 7 (a), one end of the packing 11 where the projection 11a is provided also has a circular shape. When the protrusion 11a is positioned at the center in the circumferential direction and the projection 11a is fitted into the recess 9c as shown in FIG. 9, an assembly structure of the block 9 and the packing 11 as shown in FIG. 4 is obtained.

What integrated this block 9 and packing 11
They are bound together by a coil spring 10 arranged so as to enclose the outer periphery. FIG. 10 shows a plan view of the assembled state of the spring 10. Since the coil spring 10 wraps the outer peripheral surface of the block 9 in the circumferential direction, when an outward force acts on the seal portion 9a of each block 9, the block 9 resists the elastic force of the coil spring 10. When the block 9 moves outward and the acting force is lost, the block 9 returns to the original position by the restoration of the coil spring 10 (FIG. 3). In such an operation, when block 9 spreads, block 9
Although there is a gap between the competitors, since the packing 11 is arranged to straddle the adjacent block 9, the packing 11
11 closes the gap, and the peripheral surface of the hose 5 remains sealed by the block 9 and the packing 11.

In the above configuration, as shown in FIG. 1, the shower head 2 is fixed by fitting the connector 2a portion thereof into the first guide 6, and can discharge water while being attached to the faucet main body 1. At this time, the seal portion 9a of each block 9 of the drain ring 8 is in contact with the peripheral surface of the base end of the connector 2a.

When the shower head 2 is pulled out, each block 9 protrudes or contracts in the radial direction due to a step at the joint portion between the connector 2a and the hose 5 and irregularities on the surface of the hose 5. For this reason, even when the sealing portion 9a presses the peripheral surface of the hose 5 by the tightening force of the coil spring 10, when the shower head 2 is pulled out by the movement of each block 9, it can be handled without feeling resistance.

The water that flows along the surface of the hose 5 when discharging water from the shower head 2 gradually flows into the holder 1a. On the other hand, the block 9 of the drain ring 8
Since the sealing portion 9a comes into contact, and the contact force is mechanically reinforced by the elastic force of the coil spring 10,
The water flowing through the hose 5 is blocked by the block 9. Then, the water blocked by the block 9 is discharged from the drain hole 6a of the first guide 6 and the hole 1b of the sleeve. Further, even if the water flowing through the hose 5 flows into the second guide 7 side beyond the block 9, the water is stopped by the weir 7b because the weir 7b is provided at the base end of the second guide 7. . Since the drainage hole 7a is provided in front of the weir 7b, the water is discharged to the outside through the hole 1c of the holder 1a.

Thus, when using the shower head 2, the hose 5
Is stopped by the drain ring 8 and discharged. If the water enters the second guide 7 side beyond the block 9, the weir 7b prevents the water from flowing downward. Therefore, even when the amount of water discharged from the shower head 2 is large and a large amount of water is transmitted through the hose 5, the infiltration of water into the faucet main body 1 is reliably prevented, and the inside of a cabinet or the like is not wetted.

Further, when returning the water to the holder 1a after discharging water from the shower head 2, the hose 5 moves inside the faucet main body 1 through the drainage ring 8. At this time, each block 9 of the drain ring 8 moves in the radial direction following the unevenness of the hose 5,
The sealing portion 9a is always brought into contact with the peripheral surface of the hose 5. For this reason, even if the hose 5 has an uneven surface such as a bellows tube, water attached to the surface can be wiped off,
Water is prevented from entering the faucet body 1, and the water is discharged from the drain holes 6a and 1b. Also, even if the movement of the hose 5 is too fast and the block 9 cannot completely wipe off the water,
Infiltration is prevented by the weir 7b of the second guide 7, and water is drained.
It is discharged from 7a and the hole 1c.

As described above, the four blocks 9 of the drain ring 8 are urged toward the center by the elastic body of the coil spring 10 and constantly maintain a uniform sealing pressure following the outer surfaces of the hose 5 and the connector 2a. Can be sealed. For this reason, compared with the case where an elastic body such as a packing is used, even if the hose 5 moves quickly, it is possible to wipe off the adhered water with a high sealing pressure, and the water in the faucet main body 1 and the cabinet is removed. Is prevented from dripping.

In the embodiment, the holder 1a for the shower head 2 is integrated with the faucet main body 1. However, instead of these, only the holder may be provided on the counter on the cabinet. Further, as the elastic body, for example, a plate spring or the like which can urge each block 9 toward the hose 5 may be used instead of the coil spring 10.

[Effect of the invention]

In the present invention, the outer peripheral side of the plurality of blocks is constrained by an elastic body, and the seal portion on the inner peripheral side of the block is brought into close contact with the surface of the hose by utilizing the elastic force of the elastic body. For this reason, when an elastic body such as a packing is directly abutted against the hose, the packing is deformed when the hose moves quickly and the sealing pressure is reduced. It can completely wipe off the water running down the hose. Therefore, even if the amount of water transmitted through the hose is large, or the hose is moved frequently, the water does not flow into the cabinet or the like, and there is no need to provide a water receiving tray or the like.

In addition, since the block moves in the radial direction by the elastic force of the elastic body, it is possible to seal even a hose having irregularities such as a bellows tube, and the specification can be expanded.
