  The connection part 31, the horizontal part 32, and the inclined part 33 are formed separately. In the downstream end portion of the connecting portion 31, a concave portion that is recessed from the rear to the front in FIG. 5 is formed in the circumferential direction of the axis line P <b> 1 (the central axis of the horizontal portion 32). 5 is formed in the circumferential direction of the axis P1 (the central axis of the horizontal portion 32). On the other hand, at the upstream end of the horizontal portion 32, a convex portion protruding from the rear to the front in FIG. 5 is formed in the circumferential direction of the axis P1 (the central axis of the horizontal portion 32). At the downstream end, a convex portion protruding from the front to the rear in FIG. 5 is formed in the circumferential direction of the axis P1 (the central axis of the horizontal portion 32). And the connection part 31 and the horizontal part 32 and the horizontal part 32 and the inclination part 33 are connected by engaging the recessed part of the connection part 31 and the inclination part 33, and the convex part of the horizontal part 32. FIG. Thereby, the horizontal part 32 can be rotated in the circumferential direction of the axis P1 (the central axis of the horizontal part 32) in a state where the connection part 31 and the inclined part 33 are fixed. That is, the extension tube 45 can be rotated in the circumferential direction of the axis P1 (the central axis of the horizontal portion 32).

  Returning to FIG. 4, the inclined portion 33 is provided with a rotation angle restricting portion 35 that restricts the rotation angle of the extension tube 45. The rotation angle restricting portion 35 is formed so as to rise from the outer peripheral surface of the inclined portion 33 on the left and right sides when the drainage joint 30 is viewed from the front, with one end extending from the inclined portion 33 to the horizontal portion.

<Operation and action>
Next, the operation and action of the drainage joint according to the embodiment of the present invention will be described with reference to FIGS.

FIG. 6 is a front view when the drainage joint according to the embodiment of the present invention is viewed from the front side. FIG. 7 is a front view when the drainage joint is viewed from the front side when the extension pipe according to the embodiment of the present invention is rotated to the right. FIG. 8 is a front view when the drainage joint is viewed from the front side when the extension pipe according to the embodiment of the present invention is rotated to the left.
6 to 8, the central axis of the extension pipe 45 is indicated by C1.

When the extension pipe 45 is arranged vertically upward, as shown in FIG. 6, the extension pipe 45 is arranged so that the central axis C1 of the extension pipe 45 coincides with the vertical direction perpendicular to the horizontal direction. Let
Next, when the extension pipe 45 is disposed to be inclined to the right with respect to the vertically upward direction, as shown in FIG. 7, the extension pipe 45 and the axis P1 (the central axis of the horizontal portion 32) are used as the rotation axis. The horizontal part 32 is rotated rightward. At this time, the extension tube 45 rotates in a state where the connection portion 31 and the inclined portion 32 are fixed. For example, the angle between the vertically upward direction and the central axis C1 of the extending tube at this time is about 25 ° when viewed from the front.
On the other hand, when the extension pipe 45 is arranged to be tilted to the left with respect to the vertically upward direction, as shown in FIG. 8, the extension pipe 45 and the axis P1 (the central axis of the horizontal portion 32) are used as the rotation axis. The horizontal part 32 is rotated leftward. At this time, the extension tube 45 rotates in a state where the connection portion 31 and the inclined portion 32 are fixed. For example, the angle between the vertically upward direction and the central axis C1 of the extending tube at this time is about 25 ° when viewed from the front.

  According to the toilet unit 10 according to the embodiment of the present invention described above, the drainage joint 30 is provided with the cleaning port 40 that opens upward at the upper end of the extension pipe 45. Can approach. In addition, since the extension pipe 45 rotates in the circumferential direction of the axis P1 connecting the toilet bowl side inlet 31a and the drain pipe side outlet 34a, the extension pipe 45 is moved to the right or left in accordance with the layout inside the toilet unit 10. It is possible to approach a foreign object by rotating in either direction. Therefore, the workability at the time of working using the cleaning port 40 can be improved.

  In addition, according to the toilet unit 10 according to the embodiment of the present invention described above, the inspection port 53 (opening) is provided on at least a part of the upper surface of the casing 50 and the front surface of the casing 50. When removing foreign matter or the like from the drainage joint 30, foreign matter or the like can be approached from above or in front of the casing 50. For this reason, workability | operativity can be improved.

  Furthermore, according to the toilet unit 10 according to the embodiment of the present invention described above, the cleaning port 40 and the extension pipe 45 are housed inside the casing 50 and are not visible from the outside. Thereby, the mischief with respect to the cleaning port 40 and the extension pipe | tube 45 can be prevented. Further, since the lid of the inspection port 53 is usually fixed to the casing 50, a relatively simple lid can be used for the extension pipe 45 provided in the casing 50. A special metal fitting or the like may not be used for fixing the lid of the extension pipe 45.

  Moreover, according to the toilet unit 10 by one Embodiment of this invention mentioned above, the extension pipe 45 is a range smaller than 90 degrees toward either the right direction or the left direction from the vertically upward direction of the drainage joint 30. Therefore, the extension pipe 45 is suppressed from being disposed below the side surface of the horizontal portion 32 of the drainage joint 30. Therefore, it is possible to suppress the water in the drainage joint 30 from leaking outside through the cleaning port 40 and the extension pipe 45.

  Further, like the two-dot chain extension tube 45 shown in FIG. 3, the extension tube 45 preferably extends above the upper surface 26 of the toilet 20 (the upper end of the bowl portion 22). Thereby, even if water accumulates in the toilet bowl 20 up to the position of the upper end of the bowl portion 22 due to foreign matter in the toilet bowl 20, it is possible to prevent water from overflowing from the extension pipe 45 into the casing 50.

<Other embodiments>
Next, another embodiment of the present invention will be described with reference to the drawings.

FIG. 9 is a cross-sectional view illustrating a toilet unit according to another embodiment of the present invention.
In the toilet unit 11 illustrated in FIG. 9, the drainage joint 30 a is provided with the extension pipe 45 so that the central axis of the extension pipe 45 is inclined rearward as compared with the drainage joint 30. Except for this, the structure of the drainage joint 30 a is the same as the structure of the drainage joint 30.

In the drainage joint 30a, since the central axis of the extension pipe 45 is inclined rearward, the operator can easily insert the cleaning tool toward the toilet 20 side. Thereby, since a foreign material etc. are pushed out to the toilet bowl 20 side, it can prevent flowing a foreign material etc. to the downstream side accidentally. Even if a large foreign object that cannot be taken out from the cleaning port 40 or passed through the extension tube 45 can be pushed back to the bowl 22 side of the toilet, it is clogged regardless of the size of the clogged one. You will be able to take out things.
Further, as in the above-described embodiment, the extension pipe 45 can be rotated in the circumferential direction of the central axis of the horizontal portion 31. Therefore, the operator can approach the foreign matter from either the left or right direction of the drainage joint 30.

FIG. 10 is a cross-sectional view illustrating a toilet unit according to another embodiment of the present invention.
In the toilet unit 12 illustrated in FIG. 10, the drainage joint 30 b further includes a guide portion 43 as compared with the drainage joint 30. Other than this, the structure of the drainage joint 30 b is the same as the structure of the drainage joint 30. The guide portion 43 is provided inside the horizontal portion 32 and extends from the lower end portion on the rear side in the duct of the extension pipe 45 to the toilet 20 side. The guide part 43 is, for example, a semi-cylindrical shape or a plate shape.

  Since the guide portion 43 extends from the lower end portion on the rear side in the duct of the extension pipe 45 toward the toilet 20, the toilet 20 along the guide 43 is removed when removing foreign matter in the toilet. A cleaning tool can be inserted in the direction of heading. Thereby, since a foreign material etc. are pushed out to the toilet bowl 20 side, it can prevent flowing a foreign material etc. to the downstream side accidentally. Moreover, since the guide part 43 is provided in the inside of the horizontal part 32, even when the extension pipe 45 is rotated in the circumferential direction, the cleaning tool is placed in the direction toward the toilet 20 along the guide part 43. Can be inserted.

FIG. 11 is a cross-sectional view illustrating a toilet unit according to another embodiment of the present invention.
In the toilet unit 13 illustrated in FIG. 11, the drainage joint 30 c is different from the drainage joint 30 in the shape of the extension pipe 45. Other than this, the structure of the drainage joint 30 c is the same as the structure of the drainage joint 30.

  In the drainage joint 30 c, the extension pipe 45 is tubular and has an upper part 46 and a lower part 47. The upper part 46 extends in the vertically upward direction. That is, the cleaning port 40 is opened at the upper end of the upper portion 46, and the central axis of the upper portion 46 is substantially parallel to the vertically upward direction. The lower part 47 is a part that connects the upper part 46 and the horizontal part 32. The lower portion 47 extends rearward and obliquely upward from the lower end. The lower portion 47 has a downwardly inclined surface that faces the toilet 20 from the upper portion 46.

  In the drainage joint 30c, since the upper part 46 extends vertically upward, an operator can easily approach foreign matters from above the drainage joint 30c. Thereby, workability | operativity can be improved. Moreover, since the lower part 47 has the downward inclined surface which goes to the toilet bowl 20, it is easy to insert a cleaning instrument toward the toilet bowl 20 side. Thereby, since a foreign material etc. are pushed out to the toilet bowl 20 side, it can prevent flowing a foreign material etc. to the downstream side accidentally.

  FIG. 12 is a cross-sectional view of a drainage joint according to another embodiment of the present invention, and FIG. 13 is a top view of the drainage joint according to another embodiment of the present invention. The drainage joint 30 d shown in FIGS. 12 and 13 has a cylindrical member 48 as compared with the drainage joint 30, and the extension pipe 45 and the cleaning port 40 are provided in the cylindrical member 48. The horizontal portion 32 is provided with a communication hole 49 that allows the extension pipe 45 and the horizontal portion 32 to communicate with each other. Other than this, the drainage joint 30 is the same.

  As shown in FIG. 12, a cylindrical member 48 is provided on the horizontal portion 32 of the drainage joint 30 d so as to cover the outer peripheral surface of the horizontal portion 32. The cylindrical member 48 is provided with a tubular extending tube 45 extending upward. A cleaning port 40 that opens upward is provided at the upper end of the extension pipe 45. Here, “upward” includes not only a vertically upward direction as viewed from a user sitting on the toilet seat 21 of the toilet 20 during normal use but also an obliquely upward direction. For example, the central axis of the tubular extension pipe 45 is provided so as to pass through the center of the cleaning port 40.

  As shown in FIG. 13, the horizontal portion 32 is provided with a communication hole 49. The communication hole 49 is an opening that opens upward, and has a flat outer shape that is long in the left-right direction when the drainage joint 30d is viewed from above. In addition, the lower end of the extension pipe 45 opens downward and communicates with the communication hole 49. Thereby, the inside of the pipe of the extension pipe 45 and the horizontal portion 32 communicates. The width of the communication hole 49 in the short direction is the same as the inner diameter of the lower end portion of the extension pipe 45.

  Since the three members of the connecting portion 31, the horizontal portion 32, and the inclined portion 33 and the cylindrical member 48 are configured separately, the three members of the connecting portion 31, the horizontal portion 32, and the inclined portion 33 are fixed. The cylindrical member 48 can be rotated in the circumferential direction of the axis P1 (the central axis of the horizontal portion 32). That is, the extension tube 45 can be rotated in the circumferential direction of the axis P1 (the central axis of the horizontal portion 32).

  The inclined portion 33 is provided with a rotation angle restricting portion 35 that restricts the rotation angle of the extension tube 45. The rotation angle restricting portion 35 is formed so as to rise from the outer peripheral surface of the inclined portion 33 on the left and right sides when the drainage joint 30d is viewed from the front, and has one end extending from the inclined portion 33 to the horizontal portion. It is formed to extend toward 32. A portion of the rotation angle restricting portion 35 extending from the inclined portion 33 toward the horizontal portion 32 is formed along the outer peripheral surface of the cylindrical member 48.

  In this embodiment, either the connection part 31 and the horizontal part 32 of the drainage joint 30d or the horizontal part 32 and the inclined part 33 may be integrally formed. Further, the three members of the connecting portion 31, the horizontal portion 32, and the inclined portion 33 may be integrally formed, and the cylindrical member 48 may be divided and attached, for example, vertically.

  Further, another embodiment will be described with reference to FIGS. The case where the connection part 31, the horizontal part 32, and the inclination part 33 of the drainage joint 30 are integrally formed is demonstrated. Further, the rotation restriction of the cleaning port 40 will be described in another embodiment. In addition, the connection part 31, the horizontal part 32, and the inclination part 33 of the drainage coupling 30 may each be formed separately or partially.

  The connection part 31, the horizontal part 32, and the inclined part 33 are integrally formed. A joint portion 34 (not shown) such as a bellows is formed behind the inclined portion 33. In another embodiment, the cleaning port 40 is formed in the inclined portion 33. However, the cleaning port 40 may be formed in the horizontal portion 32. The cleaning port 40 is provided with a lid 102.

  The connecting portion 31, the horizontal portion 32, and the inclined portion 33, which are integrally formed, include a collar portion 80 that protrudes in the outer peripheral direction from the outer periphery particularly near the connecting portion 31 and the horizontal portion 32. The flange portion 80 is substantially the same as the outer periphery of the connection portion 31 and the horizontal portion 32, and has a protruding portion 82 that protrudes only from the upper portion. That is, the flange portion 80 is formed in a circular shape when viewed from the front so that the outer peripheral edges of the connection portion 31 and the horizontal portion 32 are enlarged, but only the upper portion protrudes larger than the outer diameter of the flange portion 80. 82 is formed.

  A clamping unit 90 is provided in front of the collar unit 80. The sandwiching portion 90 is attached to the support member 100 (FIG. 15) with screws, and the flange portion 80 is sandwiched between the sandwiching portion 90 and the support member 110. By sandwiching the flange 80, the drainage joint 30 is prevented from moving in the front-rear direction.

  The clamping part 90 is formed of a U-shaped metal plate. A rotation angle restricting portion 35 a is provided at two ends of the sandwiching portion 90. The rotation angle restricting portion 35 a extends from the end portion of the sandwiching portion 90 to a position where the metal plate exceeds the protruding portion 82 toward the rear. That is, the rotation angle restricting portion 35a extends toward the flange portion 80, and the metal plate extends to a position where it overlaps with the protruding portion 82 in a side view. Therefore, when the drainage joint 30 is rotated, the projecting portion 82 and the rotation angle restricting portion 35a come into contact with each other, so that the drainage joint 30 cannot be further rotated.

  As can be seen from FIGS. 15 and 16, the support member 100 is screwed to the support body 70. The drainage joint 30 is disposed so that the flange 80 is disposed in front of the support member 100. Further, the clamping unit 90 is fixed to the support member 100 with screws. Even if the drainage joint 30 is rotated in the left-right direction in this state, the drainage joint 30 cannot rotate any further because the protruding portion 82 hits one of the left and right rotation angle restricting portions 35a.
