[0008] <Embodiment 1> A first embodiment of the floor structure 11 of the bathroom 10 of the present disclosure will be described below with reference to Figures 1 to 9. In the following description, the F direction in Figures 1 and 2 is defined as the front in terms of the front-to-rear direction of the floor structure 11. The H direction in Figure 1 is defined as the up direction in terms of the up-down direction. The R direction in Figures 1 and 2 is defined as the right direction in terms of the left-to-right direction.

[0009] The floor structure 11 of this embodiment includes a drainage basin 12, a floor surface 20, and an outer peripheral edge portion 15 that surrounds the drainage basin 12 and the floor surface 20. In a plan view of the floor structure 11 from above, the outer peripheral edge portion 15 forms a rectangle with its long sides oriented in the left-right direction.

[0010] The outer peripheral edge 15 is composed of a front edge 16, a pair of symmetrical side edge portions 17, and a rear edge portion 18. The front edge portion 16 is a portion that extends in the left-right direction along the front edge of the floor structure 11. The pair of side edge portions 17 are portions that extend forward from both the left and right ends of the front edge portion 16. The rear edge portion 18 is parallel to the front edge portion 16 and is a portion that connects the rear ends of the pair of side edge portions 17. An entrance (not shown) to the bathroom 10 is located in part of the rear edge portion 18.

[0011] The drainage manhole 12 is positioned so as to be in contact with the center of the front edge 16 in the left-right direction. The planar shape of the drainage manhole 12 is rectangular. The drainage manhole 12 is positioned so as to be adjacent to the lowest part of the floor surface 20. The upstream end of the drain pipe 13 is connected to the drainage manhole 12. Hot water that flows into the drainage manhole 12 from the floor surface 20 passes through the drain pipe 13 and is discharged into a sewer hole (not shown).

[0012] The floor surface 20 has multiple ridgelines 21-24, one confluence 25, and multiple inclined surfaces 31-34. In the first embodiment, the boundary lines between two inclined surfaces 31-34 that have different inclination angles relative to the horizontal and are arranged adjacent to each other are defined as the ridgelines 21-24. The multiple ridgelines 21-24 are composed of a pair of symmetrical oblique valley ridgelines 21, one central valley ridgeline 22, a symmetrical corner valley ridgeline 23, and a pair of symmetrical mountain ridgelines 24. The point where one ends of the multiple ridgelines 21, 22, and 24 other than the corner valley ridgeline 23 converge is defined as the confluence 25. The confluence 25 is located at the center of the floor surface 20 in the left-right direction and behind the drainage basin 12.

[0013] The pair of diagonal valley ridgelines 21 are ridgelines that linearly connect the confluence 25 to rear corners 26, where the side edges 17 and rear edge 18 of the outer peripheral edge 15 are connected at right angles. The diagonal valley ridgelines 21 extend diagonally relative to the side edges 17 and rear edge 18. The pair of mountain ridgelines 24 are ridgelines that linearly connect the left and right side edges 17 to the confluence 25. The pair of mountain ridgelines 24 are parallel to the front edge 16 and rear edge 18, and extend linearly between the left and right side edges 17. The central valley ridgeline 22 is a ridgeline that linearly connects the confluence 25 to the opening edge 12E of the drainage manhole 12.

[0014] Of the pair of corner valley ridgelines 23, the right corner valley ridgeline 23 is a ridgeline that linearly connects a position slightly to the left of the right end of the leading edge 16 to a position slightly behind the front end of the right side edge 17. The left corner valley ridgeline 23 is a ridgeline that linearly connects a position slightly to the right of the left end of the leading edge 16 to a position slightly behind the front end of the left side edge 17. The corner valley ridgeline 23 is located forward of the mountain ridgeline 24. The drainage basin 12 is located between the left and right corner valley ridgelines 23. The corner valley ridgeline 23 is connected to the leading edge 16 that extends along the drainage basin 12. The corner valley ridgeline 23 is located near a front corner 27 of the outer circumferential edge 15 where the leading edge 16 and the side edge 17 are connected at a right angle. The corner valley ridgeline 23 is located at a position separated from the ridgelines 21, 22, 24 other than the corner valley ridgeline 23 and the confluence 25.

[0015] The multiple inclined surfaces 31-34 are areas defined by any one of the multiple ridge lines 21-24 and a part of the outer peripheral edge portion 15. The inclined surfaces 31-34 shown in Figures 3-9 are exaggerated by five times the gradient to clearly show the inclination angle. The multiple inclined surfaces 31-34 include a first inclined surface 31, a pair of left and right second inclined surfaces 32, a pair of symmetrical corner inclined surfaces 33, and a pair of symmetrical adjacent inclined surfaces 34.

[0016] The first inclined surface 31 is an isosceles triangular region of the floor surface 20 defined by the rear edge portion 18 and a pair of oblique valley ridgelines 21. The first inclined surface 31 is composed of only one plane. The first inclined surface 31 slopes downward toward the front edge portion 16. As shown in FIG. 2, the inclination direction of the first inclined surface 31 in plan view is perpendicular to the front edge portion 16 and the rear edge portion 18, and is oblique to the oblique valley ridgelines 21. The arrows shown in FIG. 2 indicate the inclination directions of the inclined surfaces 31 to 34.

[0017] The second inclined surface 32 is a right-angled triangular region of the floor surface 20 defined by the side edge portion 17, the oblique valley ridge line 21, and the mountain ridge line 24. The second inclined surface 32 is composed of only one plane. The second inclined surface 32 slopes downward toward the oblique valley ridge line 21. The inclination direction of the second inclined surface 32 in plan view is parallel to the leading edge portion 16 and the trailing edge portion 18, and is oblique to the oblique valley ridge line 21. The inclination angle of the second inclined surface 32 is the same as the inclination angle of the first inclined surface 31.

[0018] The oblique valley ridgeline 21 is a boundary line between the adjacent first inclined surface 31 and second inclined surface 32, which are angled at less than 180°. The oblique valley ridgeline 21 slopes downward from the rear corner 26 of the outer peripheral edge 15 toward the confluence 25. The oblique valley ridgeline 21 functions as a flow path that guides the water on the first inclined surface 31 and the water on the second inclined surface 32 toward the confluence 25.

[0019] The corner inclined surface 33 is a right-angled isosceles triangular area of ​​the floor surface 20 defined by the front edge 16, the side edge 17, and the corner valley ridge 23. The corner inclined surface 33 is located at two corners 20C on the front side of the floor surface 20. Like the drainage basin 12, the corner inclined surface 33 is located so as to be in contact with the front edge 16. The corner inclined surface 33 is composed of only one plane. The corner inclined surface 33 slopes downward toward the corner valley ridge 23 and the drainage basin 12. In a plan view, the inclination direction of the corner inclined surface 33 is parallel to the front edge 16 and oblique to the corner valley ridge 23. The inclination angle of the corner inclined surface 33 is the largest among all the inclined surfaces 31 to 34.

[0020] The adjacent slope 34 is a region of the floor surface 20 adjacent to the corner slope 33 via the corner valley ridge 23. The adjacent slope 34 is an irregularly shaped region defined by the front edge 16, the opening edge 12E of the drainage basin 12, the central valley ridge 22, the mountain ridge 24, and the corner valley ridge 23. The adjacent slope 34 is composed of only one plane. The corner valley ridge 23 is the boundary line between the adjacent corner slope 33 and the adjacent slope 34, which are at an angle smaller than 180°. In a direction parallel to the front edge 16, the inclination angle of the corner slope 33 is greater than the inclination angle of the adjacent slope 34.

[0021] The adjacent slope 34 is adjacent to the second slope 32 via a ridgeline 24. The ridgeline 24 is the boundary line between the adjacent second slope 32 and the adjacent slope 34, which are at an angle greater than 180°. The left and right adjacent slopes 34 are arranged adjacent to each other via a central valley ridgeline 22. The central ridgeline is the boundary line between the left and right adjacent slopes 34, which are at an angle less than 180°. The downstream end of the oblique valley ridgeline 21 is connected to a confluence 25, which is the upstream end of the central ridgeline. The central valley ridgeline 22 functions as a flow path for guiding water on the first slope 31, the second slope 32, and the adjacent slopes 34 to the drainage basin 12.

[0022] In a direction parallel to the leading edge 16, the adjacent inclined surface 34 slopes downward from the corner valley ridge line 23 and the side edge 17 toward the catchment basin 12 and the central valley ridge line 22. In a direction parallel to the side edge 17, the adjacent inclined surface 34 slopes downward from the ridge line 24 toward the leading edge 16 and the corner valley ridge line 23. The inclination angle of the adjacent inclined surface 34 in the direction parallel to the leading edge 16 is the same as the inclination angle of the adjacent inclined surface 34 in the direction parallel to the side edge 17. In a plan view, the inclination direction of the adjacent inclined surface 34 is at an oblique angle of 45° with respect to the ridge line 24, the leading edge 16, and the side edge 17. The adjacent inclined surface 34 slopes downward as a whole from the end of the ridge line 24 on the side edge 17 side toward the catchment basin 12.

[0023] Water on the first slope 31 flows from the trailing edge 18 toward the leading edge 16 and the diagonal valley ridge 21, then along the diagonal valley ridge 21 toward the confluence 25. Water on the second slope 32 flows toward the diagonal valley ridge 21 and along the diagonal valley ridge 21 toward the confluence 25. Water that reaches the confluence 25 travels along the central valley ridge 22 to the catchment basin 12. Water on the corner slope 33 flows toward the corner valley ridge 23, passes through the corner valley ridge 23, and reaches the adjacent slope 34. Water on the adjacent slope 34 flows toward the leading edge 16, the catchment basin 12, or the central valley ridge 22. Water that reaches the leading edge 16 travels along the leading edge 16 toward the catchment basin 12. Water that reaches the central valley ridge 22 travels along the central valley ridge 22 toward the catchment basin 12. Water that reaches the catchment basin 12 is discharged through the drain pipe 13.

[0024] Since less water falls from corners 20C of floor surface 20 than from the center of floor surface 20, there is a concern that water may easily stagnate. In the first embodiment, corner inclined surface 33, which has the largest inclination angle among inclined surfaces 31 to 34 that make up floor surface 20, is provided at corners 20C of floor surface 20. Even if the amount of water is small, water flows down toward drainage basin 12 due to the steepness of the gradient at corner inclined surface 33.

[0025] The floor structure 11 of the bathroom 10 of this first embodiment includes a drainage manhole 12, a floor surface 20 that forms a flow path toward the drainage manhole 12, and an outer peripheral edge 15 that surrounds the drainage manhole 12 and the floor surface 20. The floor surface 20 has a corner valley ridge 23 whose ends connect to the front edge 16 and the side edge 17 that form the corner 20C of the floor surface 20 of the outer peripheral edge 15. With this configuration, at the corner 20C of the floor surface 20, a corner slope 33 defined by the front edge 16, the side edge 17, and the corner valley ridge 23 of the outer peripheral edge 15 slopes downward toward the corner valley ridge 23. Even if the amount of water on the corner slope 33 is small, the water on the corner slope 33 flows toward the drainage manhole 12. This prevents water from remaining in the corner 20C of the floor surface 20.

[0026] The floor surface 20 includes a corner inclined surface 33 and an adjacent inclined surface 34. The corner inclined surface 33 is a region of the floor surface 20 defined by the corner valley ridge 23, the front edge 16, and the side edge 17, and slopes downward toward the valley ridge. The adjacent inclined surface 34 is a region adjacent to the corner inclined surface 33 via the corner valley ridge 23, and slopes downward toward the drainage basin 12. The inclination angle of the corner inclined surface 33 is greater than the inclination angle of the adjacent inclined surface 34. With this configuration, because the inclination angle of the corner inclined surface 33 is greater than the inclination angle of the adjacent inclined surface 34, water on the corner inclined surface 33 passes through the adjacent inclined surface 34 and flows into the drainage basin 12.

[0027] The corner inclined surface 33 is inclined downward toward the drainage basin 12. With this configuration, water on the corner inclined surface 33 reaches the drainage basin 12 via a short path. The inclination angle of the floor surface 20 is greatest at the corner inclined surface 33. With this configuration, water on the corner inclined surface 33 reliably flows out toward the drainage basin 12.

[0028] <Other embodiments> The present disclosure is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included within the technical scope of the present disclosure. The shape of the outer peripheral edge of the floor structure in plan view may be asymmetrical. The shape of the multiple ridgelines that make up the floor surface may be asymmetric in plan view. The corner valley ridgeline is not limited to being a single straight line, but may be made up of multiple straight lines, may be made up of straight lines and curved lines, or may be made up of curved lines only. The corner valley ridge may be connected to an outer edge that is different from the outer edge along the catch basin. The number of corner valley ridges is not limited to two, but may be one or three or more. The planar shape of the plurality of inclined surfaces that make up the floor surface may be asymmetrical. The corner slope may be sloped downward toward a position different from the catch basin. In this case, hot water that falls on the corner slope flows along the corner valley ridge and reaches the catch basin. The direction of inclination of the corner inclined surface is not limited to a direction oblique to the corner valley ridge line, but may be a direction perpendicular to the corner valley ridge line. The shape of the corner inclined surface in plan view is not limited to an isosceles triangle, but may be a scalene triangle. The corner inclined surface is not limited to a flat surface, but may be a curved surface, or may be a combination of a flat surface and a curved surface. The corner slope and the corner valley ridge may be in contact with a third outer edge that is different from the first outer edge that is in contact with the drainage basin. The location of the drainage basin is not limited to a location along the outer peripheral edge, but may be a location spaced apart from the outer peripheral edge. The location of the drainage manhole may be shifted to either the left or right of the center position in the left-right direction of the floor structure. The adjacent slope may be sloped downward toward the corner valley ridge. In this case, too, hot water that falls on the adjacent slope flows along the corner valley ridge to reach the catch basin.
