In addition, for example, when the entrance / exit portion is determined at the position of the wall mounting member 2-1, the wall mounting members 2-1 and 2-2 are replaced with different ones.

To mount the wall mounting member 2 in the drain recess 14, the front leg 20 is placed on the stepped portion 14a of the drain recess 14, and the outer end P of the drain recess 14 coated with the sealing material is attached to the rear leg. After the wall mounting member 2 is aligned by being inserted into the portion 21, for example, a fixing screw is screwed from the rear leg portion 21 side to the outer end portion P side. Then, the space between the front leg portion 20 of the wall mounting member 2 and the stepped portion 14a of the drainage recess 14 is closed with a soft sealing material T, and the connection portion of the wall mounting members 2-1 and 2-2 and the wall mounting member 2 If the sealing material is applied to the connecting portions between the wall mounting members 1 and 2-3 and the wall mounting portion 13 of the floor pan 1, the drain recess 14 is covered with the wall mounting member 2 without any gap, and the wall mounting member 2 is attached to the floor pan 1. The installation work is completed.

Next, after the floor pan 1 to which the wall mounting member 2 is attached is installed on the installation surface of the bathroom forming space of the building,
The wall panel 4 is installed on the wall mounting part 13 and the wall mounting member 2 of the floor pan 1, and on the drain recess 14 of the floor pan 1 and the floor part D1 of the dressing room D left for forming the entrance / exit. Install the door frame 3. To attach the door frame 3 to the floor pan 1 side, the support portion 30a is placed on the stepped portion 14a of the drainage recess 14, and the outer end portion P of the floor pan 1 with the seal material applied is inserted into the recess 30b. The bending portion 30c is placed on the cutout portion of the floor portion D1 of the dressing room D, and then the fixing screw N is screwed from the lower frame portion 30 to the floor portion D1 side of the dressing room D. In this case, a sealing material is applied to the connecting portion between the wall mounting members 2-2 and 2-3 and the door frame 3, and the space between the door frame 3 and the stepped portion 14a is closed by the sealing material T to drain water. The recess 14 is covered by the door frame 3 without any gap.

Subsequently, the ceiling panel and the like are installed on the wall panel 4, the door is installed in the door frame 3, and the bathtub is installed on the bathtub installation portion 10 of the floor pan 1. Then, a water tap and the like are attached to the inside, and necessary water supply, drainage pipes, and the like are performed to complete a bathroom with this bathroom unit.

Next, the operation and effect of this bathroom unit will be described. In this bathroom unit, a drainage recess 14 is formed on the outer peripheral portion of the floor pan 1 on the side of the washing place 11, and along the drainage recess 14 formed at a position lower than the outer edge M1 of the washing floor M on the same horizontal plane. Since the wall mounting member 2 and the door frame 3 are installed on the support portion of the floor pan 1 so as to cover the drainage recess 14, the wall mounting member 2 and the door frame 3 do not change the shape of the floor pan 1. By simply changing the positions of and, at any position on the outer periphery of the floor pan 1 where the entrance / exit can be provided, the entrance / exit can be easily formed without forming a step with the washing floor M or the floor R of the changing room D. Can be formed. In this case, in the lower frame portion 30 of the door frame 3, the water passage Q
Since the drainage opening 30e communicating with the is formed, even when a large amount of drainage flows to the door frame 3 side due to, for example, a sudden overflow of water from the bathtub side to the washing area 11 side of the floor pan 1. The drainage flows through the drainage opening 30e to the water passage Q side and does not flow out to the dressing room D side.

In this bathroom unit, the space between the door and the door frame 3 is sealed with a floor packing or a side packing,
In addition, since the drainage opening 30e of the door frame 3 is formed outside the positions (water blocking lines) of these packings, drainage reaching the door frame 3 side is first blocked by this door, Only the drainage leaking from between the door and the floor packing or the side packing is discharged to the water passage Q side through the drainage opening 30e. Therefore, the amount of wastewater flowing through the water passage Q can be reduced, and the water passage Q can be made smaller accordingly. In addition, in this bathroom unit,
Even if the drainage exceeds the drainage opening 30e, this drainage is blocked by the water blocking packing S attached to the lower frame portion 30 of the door frame 3, so that it does not flow out to the dressing room D side. .

By the way, since the drainage on the washing place 11 flows to the side of the water collecting part 11a on the floor M of the washing place and flows into the drain trap through the opening 11b, when a large amount of hot water overflows from the bathtub. A large amount of drainage does not flow to the door frame 3 side except when drainage flows toward the door and the entrance / exit portion side. In addition, the drainage in the water passage Q is divided into two parts, and is discharged onto the bottom part 10a of the bathtub installation part 10 and then passes through the opening part 11b formed at the bottom part of the water collection part 11a from this bottom part 10a. , Pour into drain trap.

On the other hand, in this bathroom unit, regardless of the position of the entrance / exit, it suffices that there is only one type of molding tool for the floor pan 1, and there is no need to cut the wall mounting part depending on the position of the entrance / exit. The production cost of the floor pan 1 can be kept low, and the problem of water leakage due to the cutting of the wall mounting portion does not occur.

Further, in this bathroom unit, since the portion of the water passage Q that is not covered by the door frame 3 is covered by the wall mounting member 2 for installing the wall panel 4, a groove lid such as grating is unnecessary. Therefore, various problems caused by the groove lid do not occur. Of course, since there is a water passage Q below the wall mounting member 2, the sealing material T between the wall mounting member 2 and the floor pan 1 is deformed or cracked due to long-term use, and the wall mounting member 2 Even if the drainage leaks downward, this drainage is flowed to the water passage Q side and does not leak out of the floor pan 1. In addition, in this bathroom unit, drainage does not collect at the lower end of the wall panel 4, and like the conventional bathroom unit, for example, when the wall panel 4 is made of PVC steel plate, the lower end is corroded. Nothing.

Further, in this bathroom unit, the wall mounting portion 22 and the water return portion 23 of the wall mounting member 2 are arranged so as to follow the horizontal portion 13a and the water return portion 13b of the floor pan 1 on the wall mounting portion 13 side. Since they are positioned, the wall panel 4 on the bathtub installation section 10 side and the wall panel 4 on the washbasin section 11 side are installed without changing the vertical height and with their inner surfaces flush with each other. can do.

Since the water passage Q is provided below the wall mounting member 2, even if there is some error in the mounting of the wall mounting member 2 on the floor pan 1, the drainage on the washing place 11 will be the floor pan 1. Therefore, the wall mounting member 2 may be mounted on the floor pan 1 not only at the factory but also at the installation site of the bathroom unit.

In addition, the water passage Q is connected to the washing section 1 of the floor pan 1.
It may be provided only on the outer side of the first side, and the water passage Q to the drain trap may be connected by the water passage Q using a pipe arranged below the floor pan 1.

With the same configuration, the same effect can be obtained.

Further, even when the doorway portion is formed by a sliding door or a folding door instead of the door, the same effect as the above case can be obtained by installing the sliding door frame or the folding door frame instead of the door frame 3. In this case, a drainage opening leading to the water passage Q is provided in the lower frame portion of the sliding door frame or the folding door frame.

Even when a bathtub with a washing place is used instead of the floor pan 1, the same effect can be obtained by using the same configuration. Like the floor pan 1, the bathtub with a washing room is also integrally formed by resin molding using a molding die, and like the case of the floor pan 1 on the side portion excluding the bathtub side of the washing area, This is because it is necessary to form an entrance / exit portion without steps. In this case, the bathtub with a washing space may be of a type in which the bathtub is dropped into a support frame provided outside the washing space.

Further, even in the case of a sanitary equipment room unit other than the bathroom unit in which the drainage flows on the floor surface, for example, a shower room unit, the floor portion is formed by the floor pan. Similar effects can be obtained.
