Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath tub mounted on a bath tub mounting portion of a bathroom floor pan in which a washing place portion and a bath tub mounting portion are integrally juxtaposed, and drainage from the bath tub is discharged to the bathroom. The present invention relates to a bathtub drainage device that discharges and removes below a floor pan.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
The bathtub 5 is placed on the bathtub placement portion 2 of the bathroom floor pan 3 in which the bathtub placement portion 2 and the bathtub placement portion 2 are integrally juxtaposed, and drainage from the bathtub 5 is discharged and removed below the bathroom floor pan 3. Bath tub drainers are known.

In the bath tub drainage device, a first drain trap 6 for collecting and removing wastewater from the washing section 1 is provided.
A second drain trap 8 protruding below the drain port 24 for collecting and removing wastewater flowing down from the drain hole 7 of the bathtub 5 is protruding downward from the bathtub mounting portion 2. In this case, a connecting pipe 19 for communicating the drain hole 7 of the bathtub 5 with the second drain trap 8 is provided.
Are connected and connected to the bottom of the bathtub 5 with support legs 21.
A space 4 corresponding to the height of the support leg 21 is formed between the upper surface of the bathtub mounting portion 2 and the bottom back surface of the bathtub 5. The connection pipe 19 is housed and piped.

The bathroom floor pan 3 is installed on the floor base plate 9 via an adjuster 20 so as to be freely adjustable in height. The height of the bathroom floor pan 3 is adjusted by the adjuster 20, and the bathroom floor pan 3 and the floor base plate 3 are adjusted. The first drain trap 6, the second drain trap 8, and the like are accommodated in a space between the first drain trap 6 and the second drain trap 8.
In this case, the floor substrate 9 is supported and fixed on a lattice-shaped joist material 11, and the floor substrate 9 is kept away from the joist material 11.
The drainage pipe 22 is connected to the first drainage trap 6 and the second drainage trap 8, and one drainage pipe 22 is penetrated through the opening 25 so as to hang down.

Therefore, in the bath tub drainage device,
Drainage from the bathtub 5 is collected from the drainage hole 7 through the connecting pipe 19 to the second drainage trap 8 projecting below the bathtub mounting portion 2, while drainage from the washing place portion 1 is collected. Water is collected into a first drain trap 6 protruding below the drain port 24 of the washing section 1, and the first drain trap 6 and the second drain trap 8 are collected.
The collected wastewater is collected by a single drain pipe 22 and is discharged and removed below the floor base plate 9.

[0006]

However, in the above-mentioned prior art, the first drain trap 6 for collecting and removing the wastewater from the washing section 1 is provided below the washing section 1 because the first drain trap 6 protrudes below the washing section 1. It is necessary to secure a space for accommodating the first drain trap 6 between the washing section 1 and the floor base plate 9. Accordingly, the height of the washing section 1 is inevitably increased, and the step size A at the entrance which is set based on the height from the floor base plate 9 to the peripheral edge of the washing section 1 becomes large, making it difficult to enter and exit the bathroom. Had become something.

Further, in this case, the second drain trap 8 protruding below the bathtub placing portion 2 hinders the bathtub placing portion 2 from being formed so as to be lower than the washing place portion 1. Therefore, the height B from the washing place section 1 to the upper edge of the bathtub 5 placed on the bathtub placement section 2
That is, the straddling dimension B when entering and exiting the bathtub 5 is increased, and it is difficult to enter and exit the bathtub 5 from the washing section 1.

Further, since the first drain trap 6 is disposed apart from the washing section 1 and the second drain trap 8 is separated from the bathtub placing section 2, the first drain trap 6 is located between the bathroom floor pan 3 and the floor base plate 9. This requires a large area of piping space, which makes maintenance of the first drain trap 6, the second drain trap 8 and other piping difficult. In order to solve this problem, if the first drain trap 6 and the second drain trap 8 are provided as one drain trap, and the drain trap is collectively drained, the drain trap is Bathtub 5 is still clogged with trash etc.
When a large amount of water is drained from the tub, there is a problem that the drainage flows back to the washing area 1 and leaks out of the bathroom.

[0009] The present invention has been invented in order to solve all the problems in the prior art described above, that is, the problem is to make it easy to get into and out of the bathroom by lowering the washing area. It is an object of the present invention to provide a bathtub drainage device which requires a small piping space, can easily perform maintenance on the piping space, and does not cause a problem that drainage from the bathtub flows back to a washing place.

[0010]

According to a first aspect of the present invention, there is provided a bath tub drainage device in which a washing place and a bath tub placing part are integrally arranged side by side on a bath tub placing part of a bathroom floor pan. Open the bathtub, place the bathtub mounting section lower than the washing area so that the drainage of the washing area flows down to the bathtub mounting section, and collect and remove the drainage flowing down from the washing area section. A first drain trap protrudes downward from the bath tub mounting part, and a second drain trap for collecting and removing waste water flowing down from the drain hole of the bath tub is provided at a position close to the first drain trap. At the bottom.

Therefore, in this case, the first drain trap for collecting and removing the wastewater from the washing area and the second drain trap for collecting and removing the wastewater from the bathtub are separately provided, so that the wastewater from the bathtub is provided separately. Large amounts of wastewater do not flow back to the washing area. Further, since the first drain trap and the second drain trap are arranged at positions close to each other, the space for accommodating the pipes connected to them is small, and the first drain trap and the second drain trap are not required. (2) Maintenance of the drain trap and other piping can be easily performed in a narrow range. Moreover, since both the first drain trap and the second drain trap are protruded below the bathtub mounting portion, there are no obstacles below the washing portion and the washing portion can be lowered, Thereby, it is possible to easily enter and exit the bathroom. Further, in this case, the drainage flowing down from the drainage hole of the bathtub is collected directly to the second drainage trap provided in the bathtub mounting portion, while the drainage of the washing portion is formed lower than the washing portion. Then, the water flows down to the bathtub mounting portion, flows through the space between the bathtub mounting portion and the bathtub, and is collected without trouble into a first drain trap provided in the bathtub mounting portion.
