DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a water tap mounting portion in a wash basin, and a method of mounting a water tap.

[0002]

2. Description of the Related Art In many conventional wash basins, as shown in FIG. 7, an upper surface (water tap mounting surface) A of a water tap mounting portion to which a water tap is mounted is a horizontal plane.

[0003]

However, when the hydrant mounting surface is horizontal as in a conventional basin, there is a problem that water splashed to the hydrant mounting surface by hand washing or the like remains without flowing. . For this reason, stains such as water deposits are left on the wash basin by the water remaining without flowing, and there is a problem in hygiene.

[0004] In order to solve this problem, there is a basin in which the faucet mounting surface A is inclined as shown in FIG. However, in this case, as shown in FIG. 9, the adapter C was required to attach the water tap B to the water tap mounting surface perpendicular to the ground. In other words, the lower surface of the hydrant mounting part is an inclined surface,
When the hydrant is fixed from below with a lock nut D screwed to the hydrant, the upper part is cut at an inclination suitable for the inclined surface between the lower surface of the hydrant attachment part and the lock nut, and the lower surface It was necessary to interpose a substantially cylindrical adapter C having a horizontal surface. In order to stably fix the adapter C with the lock nut D, it is necessary that the adapter C does not move at the time of tightening or that the adapter C is thickened and stabilized. In addition, this adapter requires the manufacture of an adapter according to the inclination angle of the hydrant mounting surface due to a change in the design of the washbasin, and the cost required for this adapter is also large.

On the other hand, as shown in FIG. 10, when the water tap B is mounted on the inclined water tap mounting surface A perpendicularly to the inclined surface, it is necessary to prevent the water tap from hitting the wall surface E. In addition, it was necessary to change the shape of the water supply pipe. Similarly, when a lift-up shower faucet is attached, as shown in FIG. 11, it is difficult to secure a space for the support pipe and the guide because of the wall surface.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a water faucet in order to eliminate water pools on a horizontal water faucet mounting surface of a basin, which occupies a large part of the prior art. In addition to having a sloping mounting surface, the sloping hydrant mounting surface also allows the hydrant to be easily mounted vertically on the ground with a `` basin hydrant mounting structure ''. To provide. In other words, when fixing the water faucet to the water faucet mounting part of the basin from below, without the need for a special adapter as in the past,
It is an object of the present invention to be able to easily attach a water tap to a basin simply by tightening a lock nut horizontally. Thereby, even if the inclination angle of the hydrant mounting surface is changed due to a change in the design of the washbasin, it is possible to cope with the cost at a low cost.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the hydrant mounting portion of the basin according to the present invention will be described in more detail below. FIG. 1 is a sectional view showing an embodiment of a washbasin 1 to which the present invention is applied. FIG. 2 is an enlarged cross-sectional view showing the hydrant mounting portion 2 of the basin 1 of FIG. 1, and shows a state in which the hydrant 3 is mounted.

As shown in these figures, the basin 1 of this embodiment has a back side (rear side) which is a wall surface side when a wash basin is installed.
In addition, a water tap mounting portion 2 for mounting the water tap 3 is formed. The upper surface (hydraulic plug mounting surface) 4 of the hydrant mounting portion 2 is formed as an inclined surface that is inclined downward toward the basin main body 5 having a drain port. Therefore, the water splashed to the hydrant mounting surface 4 is
Is inclined to the drain port side, and there is no possibility that water will accumulate on the hydrant mounting surface 4 and sanitation is achieved. The inclination angle of the hydrant mounting surface 4 is not particularly limited, but is set to, for example, about 10 to 65 degrees, preferably about 20 to 50 degrees with respect to the horizontal plane.

A part of the hydrant mounting portion 2 has a shape dug down. In this embodiment, it is dug down in a substantially cylindrical shape. The digging portion 6 is arranged along the vertical direction with respect to the ground, the lower surface is formed in a horizontal plane 7, and the upper surface is arranged so as to be opened in the same plane as the inclined hydrant mounting surface 4. I have. A hydrant mounting hole 8 is formed inside the dug portion 6 so as to penetrate vertically. The hydrant mounting hole 8 in the illustrated example is formed with stepped holes 8a and 8b in which the bottom wall of the dug portion 6 has a small diameter.
It has been. The hole diameter of the bottom wall portion 8b is set to a diameter substantially matching the outer diameter of the water supply pipe 3a of the water faucet 3.
On the other hand, the hole diameter of the upper side 8a from the bottom wall is formed slightly larger than the outer diameter of the water supply pipe 3a. Specifically, the diameter is substantially matched with the outer diameter of the rim 10 of the cover 9 described later.

Next, an example of a specific method of forming the basin 1 having the above-described configuration will be described. FIG. 3 is a cross-sectional view showing a gypsum mold 11 for molding the basin 1 of the present embodiment.

As shown in FIG. 1, an upper mold 12 and a lower mold 13 made of gypsum are used for forming a base mold of the washbasin 1. In the mold 11, the upper mold portion 12 has a concave shape, and the lower mold portion 13 has a convex shape. And
Slurry in the gap between the upper mold 12 and the lower mold 13
, And water is extracted from the slurry portion adhered to the inner surface of the gypsum mold 11 by the water absorbing power of the gypsum.
After the slurry on the part which is to be in contact with the lower mold 13 is solidified, the slurry which has not been solidified inside is removed from a slurry outlet formed below or the like. Thereby, the inside of the basin 1 can be formed hollow in a required portion. In this embodiment, the hydrant mounting portion 2 is composed of only the solidified slurry due to the water absorbing force from both the upper mold 12 and the lower mold 13.

Then, the base mold formed as described above is removed from the mold frame 11, and thereafter, the basin 1 is manufactured through the same steps as in the case of ordinary sanitary ware. This makes it possible to manufacture the basin 1 in which the hydrant mounting surface 4 is inclined and the lower surface 7 of the hydrant mounting portion 2 is a horizontal surface.

FIG. 4 is an enlarged sectional view showing a part of the vertical type mold 11. In this figure, a portion shown by a broken line is a pipe 1 made of PVC or the like.
4, the slurry is injected into the mold 11 from a pipe 14 opened outside the mold (downward in the illustrated example). Then, after a lapse of a predetermined time, the portion 1 in contact with the surface of the form 11
Since only 5 is hardened, the unhardened slurry 16 can be extracted with the pipe 14 to produce a hollow inner mold. The hydrant mounting hole 8 formed in the dug portion 6 may be formed in advance by the mold 11 or may be opened after being taken out of the mold 11.

Next, the basin 1 manufactured as described above.
Next, a method of attaching the water tap 3 will be described. The hydrant 3 is attached to the hydrant attachment 2 of the basin 1 in a state perpendicular to the ground. Specifically, after inserting the water supply pipe 3a of the water tap 3 into the water tap mounting hole 8 formed in the dug part 6 of the water tap mounting part 2, it is tightened with a lock nut 17 from below. At this time, hydrant 3
, A cover 9 is attached at a position above the hydrant attachment portion 2. The cover 9 covers the dug portion 6 of the hydrant mounting portion 2.

That is, in the present embodiment, the diameter of the hydrant tap mounting hole 8 is formed with a margin slightly larger than the diameter of the water supply pipe 3a of the hydrant tap 3. Moreover, when the basin 1 is formed in the first place, the digging portion 6 of the hydrant mounting portion 2 needs to form a draft for smoothly pulling out the lower mold 13 in FIG. Since it is inevitable that the diameter of the hole 8 increases toward the upper part of the opening, a gap is formed between the outer peripheral surface of the water tap 3 (3a) and the inner peripheral surface of the water tap mounting hole 8 (8a). Would. Therefore, in order to hide this gap, the inclined cover 9 is attached.

As shown in FIG. 2, the cover 9 of this embodiment is formed in a substantially frustoconical cylindrical shape. That is,
The cover 9 is formed on an inclined surface 9a that expands radially outward as the outer peripheral surface goes downward, and the upper surface 9b is formed on a horizontal surface with respect to the ground, while the lower surface 9c is formed with the hydrant mounting surface 4. It is formed on a suitable slope. In the center, a hole 9d through which the water tap 3 is passed is formed penetrating along the vertical direction. At the lower end of the cover 9, a rim 10 inserted into the upper opening of the dug portion 6 projects downward and is integrally formed. In the illustrated example, a substantially cylindrical rim 10 is formed to protrude downward along a hole 9d formed at the center. The rim 10 is fitted into the upper opening of the hydrant mounting hole 8 (8a) when the cover is mounted, thereby preventing the hydrant 3 and the like from wobbling.

The upper end 9b of the cover 9 is in contact with a step (projection) 3b formed on the upper part of the faucet 3, while the lower end 9c is attached to the faucet via a packing 18. It is mounted in contact with the surface 4. Then, the water tap 3 is firmly fixed and attached to the basin 1 by screwing a lock nut 17 screwed into the screw portion 3c of the water supply pipe 3a so as to press the lock nut 17 against the lower surface 7 of the dug portion 6. That is, since the lower surface 7 of the dug portion 6 is a horizontal surface, the lock nut 17 may be tightened so as to be pressed against the horizontal surface 7. The packing 19 and the flat washer 2 are provided between the lock nut 17 and the lower surface 7 of the dug portion 6.
0 is interposed.

In the basin 1 of the above embodiment, the hydrant mounting surface 4 is provided with an inclination, so that problems such as dirt due to water accumulation on the conventional horizontal hydrant mounting surface can be solved. In addition, since the lower surface 7 of the hydrant mounting portion 2 is dug by making the hydrant mounting portion 2 horizontal, the lock nut tightening surface from the lower portion can be made horizontal. Therefore, it is possible to reduce the cost for manufacturing the adapter.

Furthermore, since the water supply pipe, the support pipe, and the guide can be used by attaching the water tap 3 vertically to the ground, it is possible to easily cope with a lift-up shower tap.

FIG. 5 is a cross-sectional view of a water tap mounting portion 2 showing an example of a state in which a lift-up shower faucet 3A is mounted on a basin 1 to which the present invention is applied. The lift-up shower faucet 3 </ b> A includes a pipe-shaped guide 22 fixed to the faucet mounting part 2, and a faucet main body 21 that can be pulled out upward with respect to the guide 22. Guide 22
Is a slender, substantially cylindrical pipe having a flange-shaped projection 22a formed at the upper end thereof so as to project radially outward, and a threaded portion 22b having a thread formed on the outer peripheral surface of the lower end thereof. It has been. In addition, the water faucet main body 21 passed through the guide 22 is configured to be able to be pulled out upward from the wash basin 1 by, for example, allowing the water supply pipe 21 to expand and contract in the longitudinal direction.

After passing the guide 22 through the hydrant mounting hole 8 of the basin 1, the screw portion 22b of the guide 22 is inserted from below.
By screwing the lock nut 17 screwed to the lower surface 7 of the dug portion 6 so as to press it, the guide 22 can be fixed to the basin 1 and the water tap 3 can be attached. By the way, in this case, the substantially frustoconical cylindrical cover 9 is
It is provided by being fitted to the guide 22, thereby covering the upper opening of the dug portion 6.

Incidentally, the structure of the hydrant mounting portion of the basin of the present invention is not limited to the configuration of the above-described embodiment, and can be appropriately changed. For example, in the above-described embodiment, an example in which the hydrant mounting hole 8 is formed in the hydrant mounting portion 2 in advance from the base type stage has been described. It may be formed in a part of the lower part of the plug mounting surface 4, and a through-hole may be opened later in the block-shaped portion to form the water tap mounting hole 8.

If the upper surface 4 is an inclined surface and the lower surface 7 is a horizontal surface, it can be manufactured without forming the dug portion 6 in the hydrant mounting portion 2. In this case, for example, it can be manufactured using a mold 11 as shown in FIG. In the mold 11 of this example, similarly to the case of the mold 11 of FIG. 4, a portion indicated by a broken line is a PVC pipe 14. Then, the slurry is injected into the mold 11 from a pipe 14 opened outside (downward in the illustrated example) of the mold 11. Then, after a lapse of a predetermined time, only the portion 15 that is in contact with the surface of the mold 11 is solidified, so that the unhardened slurry 16 is extracted with the pipe 14, thereby making it possible to manufacture a hollow inner mold. It becomes possible. Then, after taking out from the mold 11, concentric through-holes may be formed in the upper surface (inclination surface) 4 and the lower surface (horizontal surface) 7 of the hydrant mounting portion 2 to form the hydrant mounting hole 8.

Further, the basin of the present invention can be made of various materials such as pottery, artificial marble, enamel, and the like, and can be applied to a combination type of an artificial marble counter and a pottery ball. It is.

[0028]

As described in detail above, according to the structure of the hydrant mounting portion of the basin of the present invention, the horizontal hydrant mounting surface occupying most of the conventional basin is inclined to prevent water accumulation. When the hydrant is attached to the inclined hydrant mounting surface vertically to the ground, at least the vicinity of the lower opening of the hydrant mounting hole is formed in a horizontal plane. Therefore,
When fixing the hydrant with a lock nut from below, no adapter is required and a conventional fitting can be used. Therefore, it is possible to significantly reduce costs.
