SOLUTION: Since the faucet box has a sealing section slidably holding the outer circumferential section of the flexible piping and the inside of a piping penetrating section and a slipping-off preventive means preventing the slipping- off of the flexible piping outside the box is stuck fast on the outer circumferential section of the flexible piping, the flexible piping is not slipped off outside the box even when a slipping-off is generated between the flexible piping and a piping joint, thus preventing a leakage of water to the wall rear side.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faucet box used for mounting a faucet or the like and installed on a wall surface or a counter surface.

[0002]

2. Description of the Related Art As a box used for mounting a faucet or the like, there is a box described in Japanese Patent Application Laid-Open No. 9-228435. This shows a state where it is installed on a pipe generally called a sheath pipe header method, a sheath pipe extended from the header is connected to a box, and a flexible resin pipe is further inserted inside the sheath pipe on the header side. After the tube is inserted into the box, it is connected to the connection fitting. The connection fitting is fixed in the box, and further, after covering the indoor opening of the box with a cover member, the faucet is connected to the connection fitting through a hole provided in the cover member.

[0003] In addition, the hermeticity of the inside of the box is ensured, so that even if water leaks in the box, there is no intrusion of water into the back of the wall, and the leak comes out to the front side of the wall to detect the leak. It is configured to be able to.

[0004]

The structure of the prior art was devised on the assumption of a small leak in the box.
For example, when a large-scale water leak occurs such that the flexible resin pipe blows off from the connection fitting, the flexible resin pipe jumps out of the box due to the water pressure, and the water leak accumulates in the sheath pipe. Normally, the hermeticity is not ensured in the sheath tube, and the accumulation of water leakage in the sheath tube can be said to be the same situation as the leakage of water to the back side of the wall.

On the other hand, one-touch connection to a flexible resin pipe (connection is possible simply by inserting a flexible resin pipe)
Although connection joints are often used and are very effective in terms of workability, on the other hand, it is easy to make construction mistakes such as insufficient connection insertion allowance, and construction mistakes compared to conventional mechanical connection joints This makes it easy for the flexible resin pipe to come off. That is, when a one-touch type connection joint is used in the structure of the related art, there is a concern that the danger of water leakage to the back side of the wall is greater than when a mechanical connection joint is used.

The present invention is used for installing a faucet or the like, and in a faucet box installed on a wall surface or a counter surface, etc.
The present invention has been devised in order to eliminate the danger as described above, and has an object to prevent water from leaking to the back side of the wall even if the flexible resin pipe comes off due to a construction error or the like.

[0007]

According to a first aspect of the present invention, there is provided a water faucet box having a box installed in an opening of a mounting surface, and a box inserted through an indoor opening of the box and housed in the box. Water supply member, a pipe penetration portion provided on one wall surface of the box, a flexible pipe penetrating the pipe penetration portion, and the flexible pipe connected to a pipe joint provided on the water supply member. Water faucet box,
The flexible pipe includes a seal portion that slidably holds an outer peripheral portion of the flexible pipe and an inside of the pipe penetration section, and further includes a retaining means for preventing the flexible pipe from falling out of the box. Because the flexible pipe does not fall out of the box even if a drop occurs between the flexible pipe and the pipe joint due to a construction error or the like, Water leakage to the back side can be prevented.

In the water faucet box according to the second aspect, since the pipe joint is a one-touch type connection joint, the one-touch type connection pipe is liable to come off particularly due to a construction error while improving workability. The danger of water leakage from the connection joint to the back of the wall can be eliminated.

In the water faucet box according to a third aspect of the present invention, the retaining member is provided with the cover member disposed so as to cover the indoor side opening at a predetermined position. Because the outer peripheral portion is in close contact with the outer peripheral portion of the flexible pipe, the retaining means can be securely adhered to the outer peripheral portion of the flexible pipe without forgetting during a series of construction work. Sex can be eliminated.

On the other hand, the water faucet box 102 has a mounting seat 103 as a cover member, a box 104, and a water supply joint 10.
5. A hot water supply joint 106 is provided. Hereinafter, a detailed description will be given according to a general construction procedure.

First, the counter opening 107a is opened in the counter 107, and the box 104 is inserted into the counter 107 from the front side of the counter. In the upper part of the box 104 is a collar 104
a counter surface 107b with the packing 104b previously attached to the lower surface of the flange 104a.
Will be temporarily placed.

Next, the flange 104 is provided from the back side of the counter.
c is applied to the counter back surface 107c while passing the box 104 through the flange opening 104d, and the box fixing screw 104e is inserted into the box screw hole 104g and the counter opening 107a through the packing 104f.
Flange screw hole 104h provided in flange 104c
(4 places in total).

As a result, the box 104 is firmly mounted on the counter surface 107b. still,
Water leakage to the back side of the counter from between the flange 104a and the counter surface 107b is prevented by the packing 104b,
Water leakage from the box screw hole 104g to the back side of the counter is prevented by the packing 104f.

Next, a flexible pipe 108 for water supply and a flexible pipe 109 for hot water supply connected from a header or the like (not shown).
To the water supply pipe penetration part 1 provided at the lower part of the box 104
04i and the hot water supply pipe penetrating portion 104j, respectively, and the water supply flexible pipe 108 and the hot water supply flexible pipe 109 are pulled out from the counter front opening 104k provided on the upper portion of the box 104 to the counter front side.

The adapter 104ia constituting the water supply pipe penetrating portion 104i is screwed and fixed to the box screw portion 104ib. Also, an O-ring 104ic as a seal member is provided inside the water supply pipe penetration portion 104i,
Before and after the O-ring 104ic, there is a flexible pipe 1 for water supply.
The straight portion 104id having an inner diameter (for example, 0.1 mm to 0.2 mm) that is a few millimeters larger than the outer diameter of the outer peripheral portion 108a (the outer peripheral portion of the hot water supply flexible pipe 109 has the same reference numeral) by several millimeters. To a few dozen millimeters (for example, 5 mm to 15 mm).

Thus, when the water supply flexible pipe 108 is passed through the water supply pipe penetration portion 104i, the O-ring 10
The flexible pipe 108 for supplying water does not enter obliquely with respect to 4ic, so that damage to the O-ring 104ic can be prevented. Also, the O-ring 1 of the water supply flexible pipe 108 after the penetration.
Since deviation from 04ic can be prevented, the sealing property is improved. Also, by using the O-ring 104ic,
Outer peripheral portion 108a of flexible pipe 108 for water supply and O-ring 1
04ic is slidably sealed, and the flexible pipe 108 for water supply can be easily pulled out and stored while maintaining the sealing property.

It should be noted that the hot water supply pipe penetrating portion 104j has the same structure as the water supply pipe penetrating portion 104i, and it is needless to say that the same effect is obtained such as prevention of damage to the O-ring and improvement of the sealing property.

Further, in both the water supply pipe penetrating portion 104i and the hot water supply pipe penetrating portion 104j, the lower end portion inside 104ie
Water supply flexible piping 108 and hot water supply flexible piping 109
Since the taper shape is larger than the outer diameter of the water supply, the work of inserting the flexible pipe 108 for supplying water and the flexible pipe 109 for supplying hot water becomes easy, and the workability can be improved.

Next, the flexible pipe 108 for water supply and the flexible pipe 109 for hot water supply drawn out from the opening 104k on the counter front side are connected to a pipe joint 105aa provided at the lower end 105a of the water supply joint 105 and the hot water supply joint 106. Connected respectively. Packing 105a is attached to the pipe joint 105aa.

The packing 105ac and the packing 105ad are also provided so that even if leakage occurs due to damage or deterioration of the packing 105ab, it is OK.

In addition, a joint claw 105ae is provided, and a flexible pipe 108 for water supply and a flexible pipe 10 for hot water supply are provided.
9 functions as a stopper for both pipes by biting into the outer peripheral portion 108a. The joint claw 105ae is bent in the insertion direction of the flexible pipe 108 for supplying water and the flexible pipe 109 for supplying hot water, and the insertion of both pipes is easy (so-called one-touch connection).

The water supply joint 105 and the hot water supply joint 106 that have been connected to the piping are housed in the box 104, respectively. When storing, the water supply joint 105 and the hot water supply joint 1
06 can be operated independently of each other, so that there is no interference between the water supply flexible piping 108 and the hot water supply flexible piping 109,
The force required for storage can be reduced, and workability is improved.

Since the axes of the lower end portion 105a and the upper end portion 105b of the water supply joint 105 and the hot water supply joint 106 are parallel to each other, the flexible water supply pipe 108 and the flexible water supply pipe 109 are hardly bent. The water supply joint 105 and the hot water supply joint 106 can be pulled out and stored, so that workability can be further improved and wasteful space inside the box 104 can be eliminated.

After housing the water supply joint 105 and the hot water supply joint 106 inside the box 104, the mounting seat 103 as a cover member is temporarily placed on the counter surface 107b while covering the upper end portion 105b of the water supply joint 105 and the hot water supply joint 106. . Thereafter, the mounting seat fixing screw 103a is inserted into the mounting seat screw hole 103b and screwed into the box screw hole 104m provided on the surface of the box 104 (total 2).
Places). As a result, the mounting seat 103 becomes the counter surface 10

There is no worry about water leaking from behind the counter.

By this operation, the water supply joint 105 and the hot water supply joint 106 are fixed between the box surface 104n at a position facing the counter opening 104k and the upper surface 103c inside the mounting seat 103 provided inside the mounting seat 103. It is stored and positioned with a gap of. In another direction, it is stored and positioned with a predetermined gap between the box side surface 104p and the mounting seat side surface 103d.

As described above, the water supply joint 105 and the hot water supply joint 1
When the hot water mixing faucet 1 is connected in a later step, the water supply joint 1 is automatically positioned to absorb the dimensional error between the axes of the water inflow portion 101d and the hot water inflow portion 101e.
05 and the hot water supply joint 106. Thereby, the dimensional accuracy between the shafts of the water inflow portion 101d and the hot water inflow portion 101e can be roughly set, which is effective in reducing the manufacturing cost. Further, since special means such as screws for fixing the water supply joint 105 and the hot water supply joint 106 are not required, the space in the box 104 can be reduced.

Next, at the bottom of the box 104, two retaining members 110 are provided. The retaining member 110 is provided with a semicircular surface 110a and a tapered surface 110b located at a position facing the semicircular surface 110a, and a retaining claw 110c made of a metal plate is fitted into the semicircular surface 110a.

An arrow-shaped portion 1 is provided at the lower end of the projection 103e.
An arrow-shaped portion 103f pushes the tapered surface 110b of the retaining member 110 in conjunction with the installation of the mounting seat 103 on the counter surface 32. At this time, the semicircular surface 110a faces the flexible pipe 108 for supplying water and the flexible pipe 109 for supplying hot water, and the semicircular surface 110a is formed by the flexible pipe 108 for supplying water and the flexible pipe for supplying hot water. It can be pressed against the sex piping 109.

As a result, the retaining claw 110c is connected to the outer peripheral portion 1 of the flexible pipe 108 for supplying water and the flexible pipe 109 for supplying hot water.
08a. As a result, the flexible piping 108 for supplying water and the flexible piping 109 for supplying hot water to the piping joint 105aa are insufficiently inserted, and the joint claw 105ae
Insufficient penetration into the flexible piping 108 for water supply
Even when the hot water supply flexible pipe 109 can easily be pulled out of the pipe joint 105aa, the water supply flexible pipe 108
Further, the flexible pipe 109 for hot water supply can be prevented from going out of the box 104.

Further, since the retaining member 110 functions in conjunction with the installation of the mounting seat 103 on the counter surface 32, the flexible water supply pipe 10 is more reliably provided.
8 and the hot water supply flexible piping 109 can be prevented from getting out of the box 104. In a state where the mounting seat 103 is removed, the retaining claw 110c does not bite into the outer peripheral portion 108a of the flexible pipe 108 for supplying water and the flexible pipe 109 for supplying hot water. Needless to say, it does not hinder the draw-out and storage of the flexible pipe 109 for use.

Next, the water inflow section 10 of the hot and cold water mixing faucet 101
1d and the hot water inflow portion 101e are passed through a mounting seat opening 103g provided at an upper portion of the mounting seat 103, and
05 and the upper end 105b of the hot water supply joint 106.
In addition, the sealing property of these connection parts is ensured by the packing 105ba.

Finally, by screwing the cap nut female screw 101ga provided inside the cap nut 101g and the mounting seat male screw 103h provided outside the mounting seat 103, the hot and cold water mixing faucet 101 and the mounting seat 103 are screwed. Is firmly fixed (as a result, the hot and cold water mixing faucet 101 is firmly fixed to the counter 107).

An emergency shutoff valve 105c which is opened only when the water inlet 101d and the hot water inlet 101e are inserted is incorporated in the water supply joint 105 and the hot water supply joint 106, so that the water supply main plug is not closed. By mistake hot water mixing faucet 10
Even if 1 is removed, it is possible to avoid a situation where water spouts.

A dowel 103i for preventing backlash is provided at the upper part of the mounting seat 103. The dowel 103i is inserted into a dowel hole 101j provided in the hot and cold water mixing faucet 101 to be attached to the hot and cold water mixing faucet 101. It plays the role of preventing backlash of the seat 103. Further, a projection 103j for preventing erroneous connection is provided on an upper portion of the mounting seat 103, and
01 is inserted into the identification hole 101k provided in the device. This makes it physically impossible to connect in the reverse piping direction, such as connecting the hot water inflow portion 101e to the water supply joint 105, thereby preventing construction errors.

With the above configuration, the packings 105ab, 105ac, 105ad, 105
Even if a leak occurs from the ba, the water leaking to the back side of the counter is caused by the O-ring 104ic, the packings 104b and 104
f. In addition, since the notch 103k is provided in a portion of the mounting seat 103 which is in contact with the counter surface 107b, leakage in the box prevents the counter opening 1 from opening.
When the water accumulates up to 04k and finally flows out from the notch 103k, the presence or absence of water leakage can be checked from the counter surface side.

A flexible pipe penetrating the pipe penetrating portion, and a faucet box in which the flexible pipe is connected and connected to a pipe joint provided in the water supply member,
The flexible pipe includes a seal portion that slidably holds an outer peripheral portion of the flexible pipe and an inside of the pipe penetration section, and further includes a retaining means for preventing the flexible pipe from falling out of the box. Because the flexible pipe does not fall out of the box even if a drop occurs between the flexible pipe and the pipe joint due to a construction error or the like, Water leakage to the back side can be prevented.

Since the pipe joint is a one-touch type connection joint, water leakage from the one-touch type connection joint to the back side of the wall from the one-touch type connection joint is likely to occur, especially when the flexible pipe is apt to come off due to a construction error while improving the workability. Danger can be eliminated.

Since the cover member installed so as to cover the opening on the indoor side is installed at a predetermined position, the retaining member is brought into close contact with the outer peripheral portion of the flexible pipe. In addition, the retaining means can be securely brought into close contact with the outer peripheral portion of the flexible pipe without forgetting in a series of construction work, and the danger of water leakage to the back side of the wall can be eliminated.
