Further, the rear wall portion 14 of the drainage receiving portion 13 is constituted by the upper portion of the rear wall 15 of the trap case 7, and the lower portion of the rear wall 15 projects downward from the bottom portion 16 of the drainage receiving portion 13. A circular discharge hole 17 penetrating front and rear is formed in the rear wall 15. The discharge hole 17 is located below the above-described drain receiving part 13. Moreover, only the upper part of the opening on the drainage receiving part 13 side of the discharge hole 17 communicates with the drainage receiving part 13, and the lower part is positioned below the bottom part of the drainage receiving part 13. A step for preventing backflow is formed between the lower inner surface of 17.

  A rectangular storage recess 18 that is long in the vertical direction is formed on the outer surface of the rear wall 15 of the trap case 7. The lower portion of the storage recess 18 is positioned below the bottom 16 of the drainage receiving portion 13, and one end opening of the discharge hole 17 is opened as a drainage port 19 from the bottom surface of the storage recess 18. In the bottom surface of the storage recess 18 formed on the outer surface of the rear wall 15, vertically long annular packing grooves 20 a and 20 b are formed in a double shape so as to surround a drainage port 19 consisting of one end opening of the discharge hole 17. Each packing groove 20a, 20b is provided with ring-shaped packings 21a, 21b, and the drain port 19 is located inside the upper part of the packing 21a provided in the inner packing groove 20a.

  A slide member 22 is provided on the outer surface of the rear wall 15 of the trap case 7 so as to be slidable in the vertical direction. The slide member 22 includes a rectangular vertical plate-like slide portion 23 and a cylindrical connection tube portion 3 protruding vertically from the slide portion 23. One end of the connecting tube portion 3 is an inflow port portion 24 opened from the front surface of the slide portion 23, and the other end portion is a connecting port portion 25 that is connected to the drain hole 2 provided in the building wall 1. The inner diameter of the inlet 24 is the same as that of the drain outlet 19. The width of the slide portion 23 is substantially the same as the width of the storage recess 18. The slide portion 23 is housed in the housing recess 18 so as to be slidable in the vertical direction, so that the slide member 22 can slide up and down within a range of 10 mm within the housing recess 18.

An outer peripheral edge portion of a rectangular vertical plate-shaped pressing member 26 is detachably attached to the outer peripheral edge portion of the outer surface of the rear wall 15 by a screw tool 27, and between the pressing member 26 and the bottom surface of the storage recess 18. By sliding up and down, the slide part 23 of the slide member 22 adjusted to an arbitrary height is clamped and fixed. In addition, packings 21 a and 21 b provided on the outer surface of the rear wall 15 are sandwiched between the slide part 23 and the rear wall 15 of the slide member 22, and the periphery of the drain outlet 19 and the connecting tube part are formed by the packings 21 a and 21 b. The periphery of the three inlet portions 24 is sealed to prevent leakage. A vertically long cylindrical insertion hole 28 is formed at the center of the pressing member 26, and the connecting cylinder 3 is inserted through the cylindrical insertion hole 28 and protrudes toward the rear of the pressing member 26.

  Here, the slide member 22 can be attached to the outer surface of the trap case 7 by being inverted up and down by storing the slide portion 23 upside down in the storage recess 18. The provided connecting cylinder 3 is formed at an eccentric position shifted in the vertical direction from the vertical center of the slide part 23. Accordingly, as shown in FIGS. 4 and 5, the trap case 7 is lowered by attaching the slide member 22 to the outer surface of the rear wall 15 so that the connection tube portion 3 is positioned below the slide portion 23. It will be for new construction placed in the position. Also, from this state, the slide member 22 is turned upside down, and the slide member 22 is attached to the outer surface of the rear wall 15 so that the connecting tube portion 3 is positioned above the slide portion 23 as shown in FIGS. Thus, the trap case 7 is for extension and remodeling in which the connecting cylinder portion 3 is arranged at a high position. Thereby, the height of the connection cylinder part 3 can be adjusted now. Specifically, in the state where the slide member 22 is mounted at a low position for new construction as shown in FIG. 4, the drainage hole 2 newly installed and the existing drainage from the state where the slide member 22 is installed at a high position for extension and reconstruction as shown in FIG. The connecting cylinder part 3 is arranged at a position lower by the height difference (35 mm) of the hole 2.

  In addition, the trap case 7 can adjust the height of the connecting cylinder portion 3 by sliding the slide member 22 up and down regardless of whether the slide member 22 is turned upside down for new construction or expansion / reconstruction. However, the vertical length of the ring-shaped packing 21a provided in the inner packing groove 20a is a sliding member regardless of whether the trap case 7 is in a newly built state or an expanded / reconstructed state. Within the sliding range 22, the inlet port 24 of the connecting cylinder portion 3 is set to a dimension positioned inside the packing 21 a, so that the packing 21 a, 21 b can be used for both new construction and expansion / reconstruction. Sealing is performed. In addition, the vertical length of the cylindrical part insertion hole 28 is such that the connecting cylindrical part 3 is within the cylindrical part insertion hole within the sliding range of the slide member 22 regardless of whether the trap case 7 is in a new construction state or an expansion / reconstruction state. 28 is set to a dimension that can be inserted.

  4 and 5, when the trap case 7 is for new construction, the center of the inlet portion 24 of the connection cylinder portion 3 is lower than the center of the drain port 19 within the slide range of the slide member 22. The upper portion of the inlet portion 24 overlaps with the drain port 19. Further, when the trap case 7 is used for extension and remodeling as shown in FIGS. 6 and 7, the slide member 22 is moved until the center of the inflow port portion 24 of the connecting tube portion 3 is located below the center of the drain port 19. In other words, the trap case 7 is shifted downward with respect to the drain port 19 in both cases of new construction and extension / reconstruction, and the lower edge of the drain port 19 A step for preventing backflow can be formed between the lower edge portion of the connecting tube portion 3 and the connecting tube portion 3. Further, when the sliding member 22 is disposed at the upper limit position for the expansion and reconstruction of the trap case 7, the center of the inlet portion 24 of the connecting cylinder portion 3 is positioned slightly above the center of the drain port 19. Thus, the construction error above the drain hole 2 can be absorbed. In addition, when the trap case 7 is used for extension / reconstruction, it is possible to completely overlap the inlet port 24 and the drain port 19 of the connecting tube portion 3 in front view.

From the bottom 16 of the waste water receiving portion 13 Yes by projecting legs 30 downwardly, the trap casing 7 leg 30 is placed on the floor 29, the floor lower portion of the leg portion 30 by a bolt or the like 29 is fixed. Further, the connecting tube portion 3 of the slide member 22 provided in the trap case 7 is connected to the drain hole 2 provided in the building wall 1. Further, the trap 6 having one end thereof connected to the drain cylinder 12 of the bowl portion 5 of the toilet body 4 is accommodated in the drain receiving portion 13 of the trap case 7 thus installed.

  The trap 6 can be rotated up and down on the other end side which is a free end of the trap 6 by driving a motor 8 provided in the trap case 7. By rotating the trap 6 in this way, When supplying water to the bowl 5 and during standby, water can be accumulated in the bowl 5 with the other end opening of the trap 6 facing upward as shown in FIG. As shown in FIG. 8B, the water in the bowl portion 5 can be discharged in a drainage posture in which the trap 6 is substantially horizontal and the other end opening is directed rearward. When the trap 6 is in the draining posture in this way, the water discharged from the other end opening of the trap 6 is received by the inner bottom surface of the drain receiving portion 13, and thereafter, the drain port 19 and the slide member 22 After passing through the connecting tube portion 3 and the drain hole 2 of the building wall 1 in this order, the water is drained to the outside through the external drain pipe 31 embedded in the building wall 1.

  Here, when installing the flush toilet in a newly built house, for example, the height of the connecting tube portion 3 is adjusted as follows. That is, when the flush toilet is installed in a newly built house, first, as shown in FIG. 4 or FIG. Then, the holding member 26 is temporarily fixed to the rear wall 15 with the screw 27 to make the trap case 7 newly constructed, so that the height of the connecting cylinder portion 3 from the floor 29 is approximately 120 mm. And Then, the slide member 22 is slid up and down to arrange the connecting tube portion 3 at the same height as the newly formed drainage hole 2, and then the holding member 26 is completely attached to the rear wall 15 by the screw tool 27. The slide member 22 is fixed by fixing.

  When the flush toilet is installed instead of an existing toilet, first, as shown in FIG. 6 or FIG. 7, the slide member 22 is set so that the connecting cylinder portion 3 is positioned above the slide portion 23. After storing in the storage recess 18, the holding member 26 is temporarily fixed to the rear wall 15 by the screw tool 27, and the trap case 7 is used for extension and renovation, whereby the height of the connecting tube portion 3 from the floor 29 is increased. Is approximately 155 mm. Next, the slide member 22 is slid up and down to place the connecting cylinder 3 at the same height as the existing drainage hole 2, and then the pressing member 26 is completely fixed to the rear wall 15 with the screw tool 27. The slide member 22 is fixed.

  Thus, in the flush toilet of this example, the slide member 22 is turned upside down and attached to the outer surface of the trap case 7 so that the height of the connecting cylinder portion 3 can be adjusted. Even when attached to the trap case 7 in a state, since at least a part of the opening of the inlet portion 24 of the connecting cylinder portion 3 overlaps with the drain port 19, it is 120 mm from the floor 29 according to the current design standard. Both the case where it is provided at a height and the case where it is provided at a height of 155 mm from the floor 29 according to the previous design standard can be handled. Further, the slide member 22 is provided on the outer surface of the trap case 7 so as to be slidable in the vertical direction, and at least a part of the opening of the inflow port portion 24 of the connection cylinder portion 3 is drained within the vertical movement range of the slide member 22. Since it overlaps with the opening 19, even if the height position of the drainage hole 2 provided in the building wall 1 is shifted up and down from the normal position due to construction errors or the like, the slide member 22 is slid up and down slightly. By adjusting, the connection port part 25 of the connection cylinder part 3 can be arrange | positioned at the same height as the height of the drain hole 2, and the connection port part 25 of the connection cylinder part 3 can be connected to the drain hole 2 easily and reliably.
