[0010] The following describes the embodiments. The same components are given the same reference numerals, and duplicated descriptions are omitted. In each drawing, some components are omitted, enlarged, or reduced as appropriate for the convenience of description. The drawings should be viewed according to the orientation of the reference numerals. The structures and shapes referred to in this specification include not only structures and shapes that strictly match the shapes referred to, but also structures and shapes that deviate by an amount of error such as dimensional error and manufacturing error. In this specification, "connection," "fixing," "mounting," and "supporting" include cases where the conditions referred to are directly met by two parties, as well as cases where the conditions are met via other members, unless otherwise specified.

[0011] (Embodiment) See Figure 1. Bathroom 100 has a bathtub 70, a bathtub front floor 80, a drainage device 10, etc. Bathtub 70 and bathtub front floor 80 are surrounded by walls 101 and 102. Water stored in bathtub 70 and water used on bathtub front floor 80 is drained by drainage device 10. Drainage device 10 is provided below a strainer 60 provided at the boundary between bathtub 70 and bathtub front floor 80.

[0012] The bathtub 70 has an apron plate 75 that fits into the side edge 71a of the upper edge portion 71 on the bathtub front floor 80 side. The apron plate 75 constitutes the side wall portion 77 of the bathtub 70.

[0013] Please refer to Figure 2. Bathtub 70 has bottom 72 and main body side wall 73 that extends upward from bottom 72 and continues to upper edge 71. Bottom 72 has drain plug portion 72a, and drain pipe 74 is connected to drain plug portion 72a. Drain pipe 74 extends to drainage device 10. End portion 74a of drain pipe 74 is disposed above water seal cylinder 20.

[0014] The upper end 75a of the apron plate 75 is fitted to the side edge 71a of the bathtub 70. The lower end 75b of the apron plate 75 is fixed to the fixing plate 78 by the screw 76. The lower end 75b is recessed toward the bathtub 70 when viewed from the bathtub front floor 80 side. The apron plate 75 is provided directly above the water storage section 11 in the drainage device 10, making it difficult to insert a conventional cylindrical water seal cylinder into the drainage device 10. In FIG. 2, when viewed from directly above the water seal cylinder 20, more than half of the outer dimensions of the upper edge 21 of the water seal cylinder 20 is overlapped and hidden by the apron plate 75, and the lower end 75b of the apron plate 75 is provided directly above the water seal cylinder 20. When viewed from directly above the water seal cylinder 20, the lower end 75b of the apron plate 75 is provided directly above the center position of the outer dimensions of the upper edge 21.

[0015] 2, bathtub 70 has an apron plate 75 as a side wall portion 77 on the side of bathtub front floor 80. The apron plate 75 may not be provided, and the main body side wall 73 of bathtub 70 may be exposed on the side of bathtub front floor 80, with the main body side wall 73 constituting the side wall portion 77 of bathtub 70. If the main body side wall 73 is provided in a position directly above the water storage section 11 in the drainage device 10, it becomes difficult to insert a conventional cylindrical water seal cylinder into the drainage device 10.

[0016] The bathtub front floor 80 has an opening 81 on its side edge portion facing the bathtub 70. A drain outlet 82 is provided below the opening 81. A cylindrical flange portion 83 is fitted into the drain outlet 82. The opening 12 of the drainage device 10 is fitted into the lower end portion of the flange portion 83 from below. The bathtub front floor 80 is continuous with a waterproof pan 84 provided below the bathtub 70.

[0017] The drainage device 10 has a cylindrical water storage section 11 with a bottom. The water storage section 11 is connected to a drainage channel 13 through which water flows. The water sealing cylinder 20 passes through an opening 81 in the bathtub front floor 80, and the upper edge 21 is hooked and fixed to a hook 83a provided on a flange section 83. The tube section 30 of the water sealing cylinder 20 protrudes below the flange section 83 and is fitted into the water storage section 11.

[0018] 2 shows the state immediately after the water seal cylinder 20 is inserted into the drainage device 10. In actual assembly work, the water seal cylinder 20 is rotated in either the clockwise or counterclockwise direction in plan view in order to hook and fix the upper edge 21 of the water seal cylinder 20 to the claws 83a.

[0019] Water from the drain pipe 74 of the bathtub 70 and the bathtub front floor 80 flows through the water seal cylinder 20 to the bottom 11b of the water storage section 11. The water that flows into the bottom 11b passes outside the water seal cylinder 20 in the water storage section 11, passes over the upper end 11a, and is discharged from the drain 13.

[0020] The drainage device 10 isolates the space on the drainage channel 13 side from the space in the bathroom 100 by storing a part of the drainage in the water storage section 11, and prevents odors on the drainage channel 13 side from flowing into the space in the bathroom 100.

[0021] Please refer to Figures 3, 4, and 5. The water seal cylinder 20 has an upper edge portion 21, a connecting portion 26, and a tubular portion 30. The upper edge portion 21 of the water seal cylinder 20 is annular, and the center of the tubular portion 30 is eccentric from the center of the upper edge portion 21 in a plan view. In the water seal cylinder 20, the direction in which the tubular portion 30 is eccentric from the center of the upper edge portion 21 is the X-axis direction, the axial direction of the tubular portion 30 is the Z-axis direction, and the direction intersecting the X-axis direction and the Z-axis direction is the Y-axis direction. When the water seal cylinder 20 is inserted into the drainage device 10, the X-axis direction and the Y-axis direction are on the horizontal plane, and the Z-axis direction faces up and down.

[0022] The upper edge 21 of the water seal cylinder 20 is annular, and a notch 22 is provided at a position that divides the circumference of the peripheral edge into four equal parts. The upper edge 21 is provided with a contact portion 23 that protrudes upward adjacent to the notch 22. The claw 83a of the flange portion 83 is inserted into the notch 22 and positioned above the upper surface 21a. By rotating the upper edge 21 in either the clockwise or counterclockwise direction, the claw 83a slides relatively on the inclined surface 23a and contacts the contact portion 23. The water seal cylinder 20 is fixed to the flange portion 83 with the claw 83a in contact with the contact portion 23. The inclined surface 23a is inclined so that its height increases slightly from the notch 22 toward the contact portion 23, suppressing vertical rattling within the flange portion 83 of the upper edge 21.

[0023] Please refer to Fig. 6. In a cross section intersecting the axial direction of the tubular portion 30, the direction in which the tubular portion 30 is eccentric from the center of the upper edge portion 21 will be referred to as the first direction F1, and the direction intersecting the first direction will be referred to as the second direction F2. The first direction F1 corresponds to the X-axis direction, and the second direction F2 corresponds to the Y-axis direction. The tubular portion 30 has an outer dimension L1 in the first direction F1 that is smaller than the outer dimension L2 in the second direction, and has a flat shape with a narrow width in the first direction F1.

[0024] The tube portion 30 has a first wall portion 31 on one side G1 in the first direction F1 and a second wall portion 32 on the other side G2. The first wall portion 31 and the second wall portion 32 are connected to each other at both ends in the Y-axis direction and extend in the Z-axis direction to form a tube shape. The one side G1 in the first direction F1 is the +X side when viewed from the center of the tube portion 30. The other side G2 in the first direction F1 is the -X side when viewed from the center of the tube portion 30.

[0025] The first wall portion 31 is formed in a curved shape that bulges toward one side G1. The second wall portion 32 is formed in a curved shape that bulges toward the other side G2. In the example shown in FIG. 6, the first wall portion 31 and the second wall portion 32 are formed in an arc shape. The first wall portion 31 is formed in an arc with a radius of curvature equal to that of the inner peripheral edge 21b (see FIG. 4) of the upper edge portion 21, except for both ends in the Y-axis direction. The second wall portion 32 is formed in an arc with a radius of curvature larger than that of the first wall portion 31, except for both ends in the Y-axis direction. The first wall portion 31 and the second wall portion 32 are connected by a smoothly changing curved surface at both ends in the Y-axis direction.

[0026] The first wall portion 31 and the second wall portion 32 are formed of an arc with a single radius of curvature except for both ends in the Y-axis direction. The first wall portion 31 and the second wall portion 32 may be formed by connecting multiple arcs with different radii of curvature except for both ends in the Y-axis direction.

[0027] The first wall 31 extends along the Z-axis from the upper edge 21 of one side G1 in the first direction F1. The second wall 32 extends along the Z-axis from the lower end 26a of the connection portion 26. The connection portion 26 is inclined so as to extend downward from the upper edge 21 of the other side G2 in the first direction F1 toward the one side G1.

[0028] Three plate-like operating parts 27 extending upward are formed on the connection part 26. One operating part 27 is provided at a position corresponding to the center of the second wall part 32, and two operating parts 27 are provided at both ends in the Y-axis direction. The operating parts 27 are operated by pinching them with fingers when attaching or detaching the water seal cylinder 20 to or from the drainage device 10.

[0029] The operation of attaching and detaching the water seal cylinder 20 to the drainage device 10 will be described with reference to Fig. 7. Since the side wall 77 of the bathtub 70 is located directly above the water storage section 11 of the drainage device 10, the water seal cylinder 20 is inserted into the opening 81 with the eccentric side of the tube section 30 facing the bathtub 70 and the side with the connection section 26 and the operating section 27 facing the bathtub front floor 80. The water seal cylinder 20 is inserted from the lower end of the tube section 30 through the opening 81 and the flange section 83 into the water storage section 11. The drain pipe 74 is made of a soft material such as rubber, and if it mechanically interferes with the installation and removal of the water seal cylinder 20, it can be bent or otherwise avoided.

[0030] The upper edge 21 of the water seal cylinder 20 is inserted into the flange portion 83 through the opening 81. The claws 83a of the flange portion 83 are inserted into the notches 22 of the upper edge portion 21. The water seal cylinder 20 is fixed to the flange portion 83 by rotating the upper edge portion 21, for example, clockwise. The water seal cylinder 20 can be inserted and rotated by pinching the operating portion 27. A hair catcher is appropriately positioned above the water seal cylinder 20 in the flange portion 83. After the water seal cylinder 20 and hair catcher are positioned, the strainer 60 is fitted into the opening 81.

[0031] When removing the water seal cylinder 20, first remove the strainer 60 and the hair catcher. The upper edge 21 of the water seal cylinder 20 is rotated, for example, counterclockwise to release the fixation, and the notch 22 of the upper edge 21 is aligned with the claw 83a of the flange 83, and the water seal cylinder 20 is pulled upward. Since the side wall 77 of the bathtub 70 is located directly above the water storage section 11 of the drainage device 10, the eccentric side of the tubular section 30 of the water seal cylinder 20 is pulled up while tilting diagonally toward the bathtub 70 and the side with the connection section 26 and the operating section 27 toward the bathtub front floor 80, just as when inserting it, and the lower end of the tubular section 30 is removed by passing through the flange 83 and the opening 81.

[0032] The drainage device 10 includes a water storage section 11 and a water seal cylinder 20 having a tubular section 30 that is inserted into the water storage section 11 from above and is offset from the center of the upper edge section 21. The tubular section 30 of the water seal cylinder 20 has an outer dimension L1 in a first direction F1 that is smaller than the dimension in a second direction F2 in a cross section intersecting the axial direction, and the tubular section 30 is formed in a curved shape that bulges on one side G1 and the other side G2 in the first direction F1. This allows the drainage device 10 to insert the water seal cylinder 20 into the water storage section 11 while tilting it obliquely, and even if the side wall section 77 of the bathtub 70 is present above the water storage section 11, mechanical interference with the water seal cylinder 20 can be suppressed, improving user convenience.

[0033] The cylindrical portion 30 of the water seal cylinder 20 has one side G1 and the other side G2 in the first direction F1 formed in an arc shape. This allows the drainage device 10 to ensure a cross-sectional area of ​​the flow path in the cylindrical portion 30 of the water seal cylinder 20 and suppress a decrease in the drainage flow rate.

[0034] The tubular portion 30 of the water sealing cylinder 20 is disposed close to one side G1 in the first direction F1 at the upper edge portion 21. This allows the drainage device 10 to expand the tubular portion 30 to the maximum extent toward the one side G1 in the first direction F1, thereby suppressing a decrease in the drainage flow rate.

[0035] The bathroom 100 includes a bathtub 70, a bathtub front floor 80 provided on the side of the bathtub 70, and a drainage device 10. The drainage device 10 includes a water storage section 11 that stores a portion of the drainage water from the bathtub 70 and the bathtub front floor 80, and a water seal cylinder 20 having a tubular section 30 that is inserted from above into the water storage section 11. A side wall section 77 of the bathtub 70 is provided above the water storage section 11 of the drainage device 10. The water seal cylinder 20 is formed with the tubular section 30 eccentrically positioned from the center of the upper edge section 21. This allows the bathtub 100 to insert the water seal cylinder 20 into the water storage section 11 while tilting it diagonally, suppressing mechanical interference with the water seal cylinder 20 and improving user convenience.

[0036] The drainage device 10 is inserted into the water storage section 11 with the eccentric side of the tubular section 30 of the water seal cylinder 20 facing the bathtub 70. This allows the bathroom 100 to secure the cross-sectional area of ​​the flow path of the tubular section 30 of the water seal cylinder 20 in the drainage device 10, and suppresses a decrease in the drainage flow rate.

[0037] The water sealing cylinder 20 of the drainage device 10 is provided with an operating part 27 at the connection part 26, and the operating part 27 can be inserted and rotated by, for example, pinching it, improving the convenience for the user. In particular, since the operating part 27 is arranged only on the side opposite to the side where the tubular part 30 is eccentric, when the operating part 27 is pointed toward the user and pinched, the side where the tubular part 30 is eccentric naturally becomes the bathtub 70 side, making it easy to understand the insertion direction and facilitating the operation.

[0038] (Modification) The first wall 31 of the water sealing cylinder 20 may be formed of an arc with a smaller radius of curvature than the inner peripheral edge 21b (see FIG. 4) of the upper edge 21, except for both ends in the Y-axis direction, in a cross section intersecting the axial direction of the tubular portion 30. The second wall 32 may be formed of an arc with a smaller radius of curvature than the first wall 31, except for both ends in the Y-axis direction, in a cross section intersecting the axial direction of the tubular portion 30.

[0039] The first wall portion 31 and the second wall portion 32 of the water seal cylinder 20 may have a linear portion in a cross section intersecting with the axial direction of the tubular portion 30. The first wall portion 31 and the second wall portion 32 may have linear connection portions at both ends in a cross section intersecting with the axial direction of the tubular portion 30.

[0040] The operating portion 27 provided on the connection portion 26 of the water seal cylinder 20 may be formed in a rod shape, a block shape, etc. The operating portion 27 may be formed in either a convex shape or a concave shape on the connection portion 26.

[0041] The drain pipe 74 for draining wastewater from the bathtub 70 may be directly connected to, for example, the body part of the water storage section 11 of the drainage device 10 .
