The present invention has been made in view of the above problems, and an object of the present invention is to provide a bathroom drainage structure capable of lowering the washroom floor without causing the bathroom space to be narrowed or the design to be deteriorated. To do.

In order to solve the above problems, the bathroom drainage structure according to the present invention is a bathroom drainage structure provided with a tub and a washroom floor adjacent to the tub, and is provided on the bottom surface of the tub. A first drainage pipe having one end connected to the drainage port and a second drainage pipe having one end connected to the second drainage port provided on the bathroom floor are provided, and the first drainage pipe and the first drainage pipe are provided. The other end of the second drain pipe is connected to a drain trap arranged under the floor of the dressing room adjacent to the bathroom without merging in the middle, and the second drain pipe faces the dressing room side. The second drainage port is arranged at a position substantially central to the longitudinal direction of the washroom floor having a longitudinal direction and a lateral direction, and has a inclined pipe portion that inclines downward. Is inclined downward toward the second drainage port, and the first drainage pipe and the second drainage pipe are configured so that the cross-sectional shape is a horizontally long flat shape. The drainage pipe is characterized in that it is bent in a plan view while being connected to the drainage trap from the second drainage port.

In the drainage structure according to the present invention, the floor of the washing place can be lowered by effectively utilizing the space under the floor of the dressing room which does not need to be inclined on the floor surface. That is, by configuring the first drainage pipe and the second drainage pipe to be connected to the drainage trap arranged under the floor of the dressing room, the drainage trap is arranged below the floor of the washing place as in the conventional case. Is unnecessary. Therefore, since it is not necessary to provide a space for accommodating the drain trap below the washroom floor, the washroom floor can be lowered without causing the bathroom space to be narrowed or the design to be deteriorated.

Further, since the other ends of the first drainage pipe and the second drainage pipe are configured to be connected to the drainage trap arranged under the floor of the dressing room adjacent to the bathroom without merging in the middle. On the upstream side of the drain trap, it is not necessary to drain both the drainage from the washing place and the drainage from the bathtub with a single drainage pipe. Therefore, it is not necessary to use a drainage pipe having a large cross-sectional area of the internal flow path so that the drainage property can be ensured even when a large amount of drainage flows into the drainage pipe from both the washing place floor and the bathtub. Therefore, it becomes easier to use drainage pipes having a small height dimension for each of the first drainage pipe and the second drainage pipe arranged under the floor of the washing place, so that the bathroom space can be narrowed and the design can be improved more reliably. It is possible to lower the floor of the washroom without causing a decrease in the amount of water.

In the drainage structure of the bathroom in this preferred embodiment, since the cross-sectional shapes of the first drainage pipe and the second drainage pipe arranged under the washing place floor are provided in a horizontally long flat shape, the cross-sectional shape is large. Compared with the case of a perfect circle shape, the first drainage pipe and the second drainage pipe can be made thinner without reducing the cross-sectional area of the internal flow path. Therefore, the floor of the washing place can be lowered more reliably without lowering the drainage capacity of the first drainage pipe and the second drainage pipe.

Further, in the drainage structure of the bathroom according to the present invention, it is also preferable that the drainage trap is a drainage trap for a washing machine pan connected to a washing machine pan arranged in the dressing room.

In the drainage structure of the bathroom in this preferred embodiment, it is not necessary to provide a drainage trap separately from the drainage trap for the washing machine pan, so that maintenance labor and member costs can be reduced.

According to the drainage structure of the bathroom of the present invention, it is possible to lower the floor of the washing place without causing the bathroom space to be narrowed or the design to be deteriorated.

FIG. 2 is a plan view of the bathroom 1 and the dressing room 2 according to the embodiment of the present invention. FIG. 3 is a back view of the bathroom 1 and the dressing room 2 according to the embodiment of the present invention. FIG. 4 is a cross-sectional view taken along the line XX of the bathroom 1 and the dressing room 2 of FIG.

The bathroom 1 has a bathtub 11, a washroom floor 12, and a wall panel 13 that surrounds the space in the bathroom 1. Drainage ports 111 and 121 are provided on the bottom surface of the bathtub 11 and the washroom floor 12, respectively. The washing floor 12 is inclined downward toward the drainage port 121 provided in the drainage recess 122 as a whole. Normally, the drainage port 121 is covered with a lid (not shown) placed on the drainage recess 122. Further, the bathtub 11 and the washing floor 12 are supported by a pedestal 7 placed on a slab surface 6 existing below the bathroom 1 and the dressing room 2.

The dressing room 2 has a floor 21 and a wall (not shown) that stands up from the peripheral edge of the floor 21. A washing machine pan 3 is attached to the floor 21, and a vanity 5 is placed on the floor 21. Further, an inspection port 211 (opening) is formed on the floor 21 (floor near the bathroom) near the entrance / exit 14 of the bathroom, and an inspection palate 212 is provided so as to close the inspection port 211. Further, the inspection palate 212 is configured as a part of the floor 21 and is also configured to be removable. With this configuration, maintenance of the drain trap 23 becomes possible. Further, a concave member 22 is attached to the peripheral edge of the inspection port 211 so as to cover the inspection port 211 from the back side. A drain trap is attached to the bottom surface of the concave member 22 so that the upper end of the drain trap 23 is exposed.

In the space above the slab surface 6 and below the washing place floor 12 and the floor 21, the drain trap 23, the drain trap 32 for the washing machine pan, the drain pipe 41 connecting the drain port 111 and the drain trap 23, and the drain A drainage pipe 42 connecting the mouth 121 and the drainage trap 23 is provided. One end of the drainage pipe 41 is connected to the drainage port 111 so as to communicate with the drainage port 111, and the other end is connected to the drainage trap 23. The same applies to the connection of the drainage pipe 42.

In the embodiment of the present invention, since the drainage pipes 41 and 42 are connected to the drainage trap 23 arranged under the floor 21 of the dressing room 2 which does not need to be inclined on the floor 21, the drainage pipes 41 and 42 are connected below the washing place floor 12. There is no need to dispose of the drain trap 23. Therefore, since it is not necessary to provide a space for accommodating the drain trap 23 below the washroom floor 12, the washroom floor 12 can be lowered without causing the bathroom space to be narrowed or the design to be deteriorated.

Further, in the embodiment of the present invention, the drainage pipe 41 having one end connected to the drainage port 111 and the drainage pipe 42 having one end connected to the drainage port 121 before the other end is connected to the drainage trap 23. It is connected to the drain trap 23 without merging with each other. That is, the drainage pipe 41 extending from the drainage port 111 side toward the drainage trap 23 side and the drainage pipe 42 extending from the drainage port 121 side toward the drainage trap 23 side are connected to the drainage trap 23 without merging in the middle. To. Therefore, it is not necessary to drain both the drainage from the washing place floor 12 and the drainage from the bathtub 11 with one drainage pipe. Therefore, it is not necessary to use a drainage pipe having a large cross-sectional area of the internal flow path so that the drainage property can be ensured even when a large amount of drainage flows into the drainage pipe from both the washing place floor 12 and the bathtub 11. Therefore, it becomes easy to use drainage pipes 41 and 42 having a small height dimension for each of the drainage pipes 41 and 42 arranged below the washing place floor 12, so that the bathroom space is not narrowed and the design is not deteriorated. The floor can be lowered.
