Abstract

PROBLEM TO BE SOLVED: To enlarge the installation possible range of a unit bath by providing a drain trap in the rear surface of a space higher than the surface for mounting a bathtub in a floor pan whose surface for mounting the bathtub is formed lower than a surface forming a washing space. SOLUTION: A drain trap 3 having a cylinder part 5 is provided in the rear surface of a washing space 11 of a floor pan 1 whose surface 12 for mounting a bathtub 2 is formed lower than the surface for forming the washing space 11, and an interval from the surface 12 for mounting the bathtub 2 to the drain trap 3 is connected by a branch pipe 4. Water flowing on the surface 12 is thus flows into the cylinder part 5 through the branch pipe 4 and the water overflowing from the top surface opening of the cylinder part 5 flows out from the drain trap 3 so as to be discharged to the drainage pipe in a building. The water flowing from the drain port 6 into a seal water cylinder 7 provided in the cylinder 5 is discharged from the drain trap 3 via the cylinder 5. This constitution allows the drain trap 3 to be installed in an elevated position so as to widen the installation possible range of a unit bath.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit bath drainage device.

[0002]

2. Description of the Related Art As a conventional unit bath drainage device, as shown in FIG. 3, a surface 12 'of a floor pan 1 in which a surface 12' on which a bathtub 2 is placed is formed lower than a surface on which a washing place 11 is formed. The drain trap 100 is provided at the lowest point of the drain. Recently, there has been an increasing demand for lowering the bathtub straddling height H, and in order to lower the height H, the surface 12 ′ on which the bathtub 2 is placed with respect to the washing place 11 must be installed at a lower position. lost.

[0003]

The washing place 11 and the surface 12 '
When the drain trap 100 is provided below the lowest point of the surface 12 ', the drain trap 10
Therefore, the distance at which the drain pipe can be connected to the drain pipe 102 is limited, and the range in which the unit bath can be installed is narrowed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a unit bath drainage device capable of increasing the mounting position of a drain trap and expanding the installable range of a unit bath.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention is directed to a place where a surface for placing a bathtub is higher than a surface for placing a bathtub of a floor pan formed so as to be lower than a surface for forming a washing place. Is provided with a drain trap on the back surface, and a portion from the surface on which the bathtub is placed to the drain trap is connected by a branch pipe.

[0006]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

In the embodiment shown in FIG. 1, the surface 12 on which the bathtub 2 is placed is formed lower than the surface on which the washing room 11 is formed, and the straddle height H of the bathtub 2 is reduced. A drain trap 3 is provided. A branch pipe 4 connects the surface 12 on which the bathtub 2 is placed to the drain trap 3.
The drain trap 3 in this embodiment is provided with a tubular portion 5 having an upper surface opening inside, and a branch pipe 4 is connected to the tubular portion 5.
Therefore, the water flowing on the surface 12 enters the tube portion 5 through the branch pipe 4, and when the tube portion 5 is full, the water overflowing from the upper surface opening flows out of the drain trap 3 and flows into the drain conduit 102 in the building. In addition, a water sealing tube 7 is provided from the drain port 6 of the washing place 11 into the cylindrical portion 5. The water that has flowed into the water sealing tube 7 flows into the tube portion 5, and the water that has overflowed from the tube portion 5 is discharged from the drain trap 3 to the outside.

FIG. 2 shows a detailed half-sectional view of the drain trap 3, and the symbol L indicates a water surface where water is constantly stored. When the position of the drain trap 3 is the same, the surface 12 'on which the conventional bathtub is mounted and the surface 12' on which the bathtub according to the present invention is mounted.
2 is shown on the left side in FIG. 2, and the difference h is about 35.
mm.

[0009] By lowering the bathtub straddling height H,
Since the step between the washing place 11 and the surface 12 becomes large, the drain trap 3 is provided on the back surface of the washing place 11, and the drainage from the surface 12 is guided to the drain trap 3 by the branch pipe 4, so that the drain trap 3 is raised. Can be installed in any position.

[0010]

As described above, according to the present invention, the surface on which the bathtub is placed is lower than the surface on which the bathtub is formed. A drain trap is provided, and the branch from the surface on which the bathtub is placed to the drain trap is connected by a branch pipe, so that the drain trap can be installed at a higher position than the drain trap on the back of the surface on which the bathtub is placed. Can be widened. For this reason, it can be installed in buildings with various plan variations.
