Faucet with wall, 35w and 35h are branch pipes to the faucet with wall 34 for bathtub, 36 is a washing place counter, and 37 is a faucet for washing place. As will be described later, the branch pipes 35w and 35h are branched from the unit outside pipe located below the outside of the bathroom unit.

Further, FIG. 8 is a vertical cross-sectional view showing the portion shown in FIG. 7 in a vertical section parallel to the wall surface, and FIG. 9 is a vertical cross-sectional view taken along a vertical plane orthogonal to the wall surface. In these figures, reference numeral 38 is a bathtub waterproof pan, 39 is a weir portion formed on the washroom side of the bathtub waterproof pan 38, 40 is a bathtub apron, 41w and 41h are unit outside pipes, and 42 is an inspection port of the weir portion 39. Is.

The bathtub waterproof pan 38 is connected to the washroom waterproof pan 32 via the weir 39. The unit outer pipes 41w and 41h are provided below the both waterproof pans 32 and 38, stand up inside the weir 39 toward the top plate, and penetrate the top plate of the weir 39 to form the unit. It is connected to the inner pipes 43w and 43h. The in-unit pipes 43w and 43h are connected to the faucet 37 for a washing place.

On the other hand, the branch pipes 35w and 35h to the faucet 34 with a wall for bathtub are the unit outside pipes 41w and 35w inside the weir 39, that is, in the space surrounded by the rising wall of the weir 39. 41 h, and extends laterally through the space in the rising wall of the weir 39 to the outside of the bathtub wall panel 33 a.

[Problems to be solved by the device]

 By the way, the unit outside pipes 41w, 41h and the branch pipes 35w, 35h are connected via a pipe joint (reference numeral omitted). However, when such a pipe joint is used, it is up to the connecting operator to make a connection. It is known that the vertical height positions of the branch pipes 35w and 35h are likely to vary. Due to such circumstances, it is difficult to accurately arrange the ends of the branch pipes 35w and 35h at the height position of the through hole of the wall panel 33. Therefore, the pipe connection to the faucet 34 with a wall for a bathtub is performed. In addition to the troublesome work, the work of assembling the bathtub wall panel 33a is hindered, which deteriorates the workability.

On the other hand, a flexible pipe may be used for a part or all of the branch pipes 35w and 35h, and the faucet with wall 34 and the unit outside pipes 41w and 41h may be connected via the flexible pipe. Conceivable. In this case, the displacement between the through hole of the bathtub wall panel 33a and the branch pipes 35w and 35h can be absorbed by the flexible pipe. However, in such a connection structure, the flexible pipe is provided outside the bathroom unit. It will be installed, which is not preferable for ensuring the waterproofness of the bathroom unit. This form is a taboo of common sense for construction of water pipes and cannot be implemented.

The present invention addresses such a conventional problem, and does not impair the waterproofness of a double waterproof pan type bathroom unit, and works for connecting a pipe to a faucet with a wall for a bathtub and a wall panel. It is an object of the present invention to facilitate the assembly work of

[0013]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is directed to a bathroom unit using a waterproof pan that extends over the bathtub side and the washroom side, and a faucet with a bathtub wall attached to the inside of a bathtub wall panel and a bathroom unit exterior. The connection structure with the unit outside piping provided in the above was configured as follows.

In the connection structure of a faucet with a wall for a bathtub according to the present invention, there is provided a pipe having a substantially U-shaped wall attached to the outside of a bathtub wall panel so as to extend in the vertical direction, and the upper end of the pipe with a wall is attached. The part is located above the upper edge flange of the bathtub, and the lower end of the pipe with wall is open to the inside of the bathtub wall panel at a position lower than the upper edge flange of the bathtub. The faucet with a wall for a bathtub is connected to the upper end of the pipe, and the outside pipe of the unit is connected to the lower end of the pipe with the wall via a flexible pipe arranged above the waterproof pan. .

[0015]

[Action]

 When connecting a pipe to a faucet with a wall for the bathtub, first attach the pipe with the wall to the outside of the bathtub wall panel, then place the bathtub panel on the support edge of the waterproof pan and assemble it. . As a result, the upper end and the lower end of the pipe with wall are opened inside the bathtub wall panel, so that it is sufficient to connect the lower end and the pipe outside the unit using a flexible pipe. Then, after installing the bathtub above the waterproof pan, a faucet with a bathtub wall can be attached to the inside of the bathtub wall panel and connected to the upper end of the pipe with a wall.

As described above, since the flexible pipe connected to the faucet with the wall for the bathtub is located above the waterproof pan, even if water leaks from the flexible pipe, this leak will not occur. It will be possible to receive it at, and do not have a bad influence on the body.

FIG. 1 is a vertical cross-sectional view showing a connection structure of a faucet with a bathtub wall according to a first embodiment of the present invention in a vertical section parallel to a wall surface, and FIG. 2 is a vertical plane perpendicular to the wall surface. FIG. 3 is a vertical cross-sectional view and FIG. 3 is an exploded perspective view.

In these drawings, reference numeral 1 is a bathtub, 2 is a bathtub waterproof pan, 3 is a washroom waterproof pan, 4a is a bathtub wall panel, 4b is a washroom wall panel, 5 is a faucet with a bathtub wall, and 6 is wash. A water counter, 7 is a faucet for a washing place, 8w and 8h are external pipes for the unit, and a waterproof pan is used separately from the bathtub side and the washing side.

A weir portion 9 is formed on the washing place side of the bathtub waterproof pan 2, and the weir portion 9 is connected to the washing place waterproof pan 3. A supporting edge 10 for the bathtub wall panel 4a is formed on the periphery of the bathtub waterproof pan 2 (shown in FIGS. 2 and 3), and the supporting edge 10 allows the bathtub wall panel 4a to be attached to the upper edge flange of the bathtub 1. It is received and supported at a lower position. The unit outer pipes 8w, 8h are routed under the both waterproof pans 2, 3 and rise inside the weir 9 toward the top plate and penetrate the top plate of the weir unit 9 to penetrate the unit. It is connected to the inner pipes 11w and 11h. Reference numeral 12 is a bathtub apron, and 13 is an inspection port provided in the weir 9.

The ends of the in-unit pipes 11w and 11h are branched into the washing place side and the bathtub side, and the branch pipes 14w and 14h on the washing place side are connected to the washing faucet 7 through the inside of the washing place counter 6. There is. On the other hand, the branch pipes 15w and 15h on the bathtub side are made of bellows-shaped flexible pipes, and are connected to walled pipes 16w and 16h which will be described later and are attached to the outside of the bathtub wall panel 4a.

On the outside of the bathtub wall panel 4a, as shown in FIGS. 2 and 3, substantially U-shaped pipes 16w and 16h with a wall are attached in the vertical direction. Both ends of the U-shaped pipes 16w and 16h are attached to a pair of upper and lower through holes formed in the bathtub wall panel 4a, and are opened to the inside of the bathtub wall panel 4a through the through holes. ing. The upper ends of the pipes 16w and 16h with walls are located at a position higher than the upper edge flange of the bathtub 1, and the faucet 5 with a bathtub wall is connected to it. The lower ends of the pipes 16w and 16h with walls are located at a position lower than the upper edge flange of the bathtub 1, and the outside pipes 8w and 8h of the unit are connected to the branch pipes 15w and 15h made of flexible pipes. Is connected.

Next, a procedure for constructing the pipe connection with the above configuration will be described. First, the bathtub waterproof pan 2 and the washroom waterproof pan 3 are installed, and the unit outside pipes 8w and 8h and the unit inside pipes 11w and 11h are connected through the top plate of the weir portion 9. In this case, the unit outside pipes 8w and 8h remain straight pipes, and it is not necessary to branch to the washing place side before connecting to the unit inside pipes 11w and 11h as in the conventional example.

The tip ends of the in-unit pipes 11w and 11h are branched into a washing place side and a bathtub side. Of these, the washing place side branch pipes 14w and 14h are connected to the washing place faucet 7. After this, the bathtub wall panel 4a is placed and assembled on the supporting edge 10 of the bathtub waterproof pan 2, and the pipes 16w and 16h with walls are attached to the outside of the bathtub wall panel 4a in advance.

Then, when the bathtub wall panel 4a having the pipes 16w and 16h with walls is placed on the support edge 10 of the bath waterproof pan 2, the lower end portions of the pipes 16w and 16h with walls are positioned farther from the upper edge flange of the bathtub 1. Open towards the inside of the unit at a low position. Therefore, inside the bathtub wall panel 4a, the branch pipes 15w, 15h on the bathtub side and the lower ends of the pipes 16w, 16h with walls are connected. In this case, the height positions of the lower ends of the pipes 16w and 16h with walls and the height positions of the connection points with the in-unit pipes 11w and 11h are unlikely to be constant, but as branch pipes 15w and 15h on the bathtub side, Since a flexible pipe is used, it can be easily connected in a form that absorbs the deviation of the height position of both.

After that, the bathtub 1 is installed in the bathtub waterproof pan 2, the faucet 5 with a bathtub wall is attached inside the bathtub wall panel 4a, and the faucet 5 with a bathtub wall is attached to the pipe 16w with a wall. , 16h. Now, the bathtub faucet 5 with a wall is connected to the unit outside pipes 8w and 8h through the walled pipes 16w and 16h and the unit inside pipes 11w and 11h, and hot water is supplied from the unit outside pipes 8w and 8h. To be done.

As described above, even if the branch pipes 15w and 15h connecting the unit outside pipes 8w and 8h and the wall-attached pipes 16w and 16h are flexible pipes, the branch pipes 15w and 15h are used for the bathtub waterproof pan 2 and the washing place. Since the water is laid above the waterproof pan 3, even if water should leak from the branch pipes 15w and 15h, the leak will be collected by the bath waterproof pan 2 and the washroom waterproof pan 3, It does not leak outside the lower side of the bathroom unit.

FIG. 4 to FIG. 6 show a second embodiment of the present invention. The second embodiment differs from the first embodiment mainly in that a bathtub / washing place waterproof pan 20 in which the bathtub waterproof pan 2 and the washing place waterproof pan 3 are integrally formed is used, and the unit outside pipes 8w, 8h are used. This is the point where the start-up position is outside the wash-room wall panel 4b.

In the bathtub / washing place waterproof pan 20 here, the rising dimension of the portion corresponding to the support edge 10 and the height dimension of the portion corresponding to the dam portion 9 of the bathtub waterproof pan 2 of the first embodiment are significantly low. It is set.

The unit outside pipes 8w and 8h are opened to the inside through the through holes of the washroom wall panel 4b, and the openings of the unit outside pipes 8w and 8h and the washroom faucet 7 are linear in the horizontal direction. Are connected through the unit internal pipes 11w and 11h, and are attached to the bathtub wall panel 4a and a T-shaped joint (omitted from the reference numeral) interposed in the middle of the unit internal pipes 11w and 11h. The pipes 16w and 16h with walls are connected via branch pipes 15w and 15h, which are flexible pipes. That is, since the branch pipes 15w and 15h made of flexible pipes are routed above the bathtub / washing place waterproof pan 20, even if water should leak, it will not damage the building side.
