2. Description of the Related Art For example, in order to draw a water supply / hot water supply pipe (hereinafter referred to as a pipe) into a bathroom unit, the pipe is passed through a wall panel from the side of the bathroom unit or drawn into the bathroom unit. From below, it is necessary to pass this pipe through the bottom of the waterproof floor pan and into the inside. In order to draw the pipe into the bathroom unit, it is necessary to draw the pipe into a bathroom counter or the like, for example, on the washroom side in consideration of the appearance inside the bathroom.

FIG. 7 shows the area around a counter 110 of a bathroom unit into which a pipe 100 is drawn from the wall panel 3 side. In this case, outside the wall panel 3 of the bathroom unit,
A sufficient space for installing the pipe 100 is required. However, the bathroom unit is often installed to fill the bathroom installation space in order to increase the space utilization efficiency, and it is often difficult to secure a sufficient piping space outside the bathroom unit. Therefore, it is often difficult to draw a pipe into the bathroom unit from the side of the bathroom unit.

FIG. 8 shows a washing area 11 of the waterproof floor pan 1.
2 shows the area around the counter 111 of the bathroom unit into which the pipe 100 is drawn from the bottom side. In this case, pipe 1
In order to hide 00, it is necessary to lower the front wall 111a of the counter 111 to the bottom of the waterproof floor pan 1. For this reason,
In such a bathroom unit, there is no space for inserting a foot below the counter 111, and there is a problem that the counter 111 becomes difficult to use. Therefore, the pipe 100 is often drawn into the bathroom from the bathtub installation section 12 side of the waterproof floor pan 1 in many cases.

[0005] On the other hand, prior to the installation of the bathroom unit, installation work of the outdoor piping is performed in the bathroom installation space. However, due to the on-site construction, the position of the joint of the outdoor piping with the bathroom unit is set. Is often difficult to determine accurately for this bathroom unit. Therefore, in order to connect the outdoor piping to the indoor piping on the bathroom unit side, the indoor piping is projected outside the bathroom unit, and the connection between the indoor piping and the outdoor piping is made outside the bathroom unit. There are many. Hereinafter, this will be described with reference to FIG.

FIG. 9 shows a lower part of a bathroom unit in which piping is drawn into a space below the bathtub 2 from the bathtub installation part 12 side of the waterproof floor pan 1. In this bathroom unit, a projecting portion 120 that forms a space below is formed at the bottom of the waterproof floor pan 1 on the side of the bathtub installation portion 12, and a lid (not shown) is formed on a part of the upper wall 121 of the projecting portion. ) Is formed.

In order to draw the pipe in this bathroom unit, first, the waterproof floor pan 1 is placed in the bathroom installation space by positioning the end (joining portion) of the outdoor pipe 101 inside the projection 120. Install. Then, the protrusion 12
For example, a hole is formed in the upper wall 121, and the indoor pipe 102 is passed through the hole, and then the outdoor pipe 101 and the indoor pipe 102 are connected using the handhole 121a.
Then, if the hand hole 121a is sealed with a lid and the area around the insertion portion of the indoor pipe 102 of the projecting portion 120 is sealed, the work of drawing the pipe into the bathroom is completed.

[0008]

However, in the above-mentioned conventional bathroom unit, the outdoor piping 101 and the indoor piping 10 are not provided.
2 has to be inserted in the narrow protruding portion 120 by inserting a hand through the hand hole 121a, and there is a problem that the connection work of this pipe is not easy. In addition, since the connection between the outdoor pipe 101 and the indoor pipe 102 is outside the bathroom unit, there is a problem that it is not easy to check the connection. Further, in this bathroom unit, it is necessary to form the projecting portion 120 for connecting a pipe to the waterproof floor pan, and there is a problem that the structure becomes complicated.

[0009] The above-mentioned problem is caused when the pipe 100 is pulled in from the side of the bathroom unit as shown in FIG. 7 or when the pipe 100 is connected to the waterproof floor pan 1 as shown in FIG.
This also occurs when pulling in from the washing area 11 side. Further, the connection between the outdoor pipe 101 and the indoor pipe 102 occurs not only in the case of providing a water supply / hot water supply pipe but also in the case of providing a reheating pipe.

[0010] As shown in FIG.
When the connecting portion between the 01 and the indoor pipe 102 is provided on the counter 130 side where the bath faucet 131 and the washing faucet 132 are provided, the surroundings of the connecting portion are pipes and the counter support 133.
And the piping work becomes difficult to that extent, and it becomes difficult to inspect around the connection. In particular, when the reheating adapter 24 is provided in the bathtub 2, since the reheating adapter 24 is provided on the counter 130 side, the piping around the connection between the outdoor piping 101 and the indoor piping 102 is further crowded. .

In view of the above, the present invention makes it possible to easily connect an outdoor pipe to an indoor pipe, easily inspect a connection portion between the outdoor pipe and the indoor pipe, and has a complicated structure.
