Summary of the Invention

Problems to be Solved by the Invention

[0004] By providing a guide portion as shown in Patent Document 1 above, it becomes easier to insert a pipe body such as a hose into the inside of a water distribution pipe. However, in order to suppress the cleaning water discharged from the pipe body from overflowing from the cleaning port, it is necessary to form the guide member large. Alternatively, it is necessary to reduce the water pressure. For this reason, from the viewpoints of portability and workability, another aspect capable of suppressing the overflow of the cleaning water is also required.

[0005] In consideration of the above facts, the present disclosure aims to provide a jig that makes it difficult for the cleaning water discharged from the pipe body to overflow.

Means for Solving the Problems

[0006] The jig according to the first aspect includes a lid capable of sealing the opening end of a branch pipe connected upward to a horizontal pipe, and a guide portion having a through hole inclined with respect to the vertical direction, the through hole being formed so that a pipe body can be inserted from above the lid downward.

[0007] In the jig of the first aspect, the open end of the branch pipe connected upward to the horizontal drawing pipe is sealed by a lid. And a through hole through which the pipe body can be inserted is formed in this lid. Since the through hole is formed in the lid that seals the open end, the cross-sectional area of the through hole is smaller than the cross-sectional area of the open end of the branch pipe. Thereby, for example, when inserting a pipe body into the horizontal drawing pipe and cleaning the inside of the pipe, compared with the case where the jig is not used, the cleaning water discharged from the pipe body is less likely to overflow.

[0008] Further, this through hole is inclined with respect to the vertical direction. For this reason, the pipe body is guided into the horizontal drawing pipe at an angle inclined with respect to the vertical direction. Thereby, compared with the case of inserting the pipe body along the vertical direction, it is easier to guide the pipe body into the horizontal drawing pipe.

[0009] In the jig of the second aspect, the bottom surface of the lid contacts the upper surface of a step formed to protrude inside the branch pipe, and the open end is sealed.

[0010] In the jig of the second aspect, the bottom surface of the lid contacts the upper surface of the step of the branch pipe, and the open end is sealed. That is, the open end is sealed by placing the lid on the step. Thereby, for example, compared with the aspect of sealing the open end by a jig of a screwing-in type for the branch pipe, the production of the jig is easy. Also, when cleaning the downstream side and the upstream side of the horizontal drawing pipe, the insertion direction of the pipe body can be easily changed only by changing the installation direction of the jig.

[0011] In the jig of the third aspect, a regulating portion for guiding the pipe body inserted into the through hole to a position where it does not interfere with the boundary portion between the horizontal drawing pipe and the branch pipe is provided on the inner peripheral wall of the through hole.

[0012] In the jig of the third aspect, a regulating portion for guiding the pipe body to a position where it does not interfere with the boundary portion between the horizontal drawing pipe and the branch pipe is provided on the inner peripheral wall of the through hole. Thereby, when the pipe body is inserted into the through hole, the tip of the pipe body is less likely to be caught by the boundary portion. For this reason, it is easy to guide the pipe body into the horizontal drawing pipe.

[0013] In the jig according to the fourth aspect, the through hole has a shape along a straight line, and is formed at an angle that guides the tube body inserted into the through hole to a position where it does not interfere with the boundary between the lateral extraction pipe and the branch pipe.

[0014] In the jig according to the fourth aspect, the through hole has a shape along a straight line. Therefore, it is easy to insert the tube body into the through hole. Further, the through hole is formed at an angle that guides the tube body to a position where it does not interfere with the boundary between the lateral extraction pipe and the branch pipe. Therefore, when the tube body is inserted into the through hole, the tip of the tube body is less likely to be caught by the boundary portion. As a result, it is easy to guide the tube body into the lateral extraction pipe.

Advantages of the Invention

[0015] According to the present invention, the cleaning water discharged from the tube body is less likely to overflow.

Modes for Carrying Out the Invention

[0017] Hereinafter, the jig according to the embodiment of the present disclosure will be described with reference to the drawings. Components denoted by the same reference numerals in each drawing mean the same components. However, unless otherwise specified in the specification, each component is not limited to one, and a plurality of components may exist.

[0018] In addition, descriptions of overlapping configurations and reference numerals in each drawing may be omitted. Note that the present disclosure is not limited to the following embodiments, and appropriate changes can be made and implemented, such as omitting configurations, replacing with different configurations, and combining one embodiment and various modifications within the scope of the object of the present disclosure.

[0019] <Drain pipe structure> Prior to the description of the jig 60 (see FIG. 2 etc.) according to the embodiment of the present disclosure, an example of the drain pipe structure 10 to which the jig 60 is applied will be described. As shown in FIG. 1, the drain pipe structure 10 includes a siphon drainage structure having a siphon drain pipe 44.

[0020] Note that the configuration of the connection portion of each pipe in FIG. 1 is shown in an omitted manner. A drain joint 18 for connecting a pipe from a plumbing fixture is provided in the drain riser 16 passing through the through-hole 14 of the building floor slab 12, and is configured to combine the drainage from the upper drain riser 16 and the drainage from the plumbing fixture.

[0021] In each floor of the building, a kitchen sink (sink) 19 as a plumbing fixture is provided. A disposer 20 is attached to the kitchen sink 19. The disposer 20 of the present embodiment has a jet flush function (also referred to as jet cleaning) that discharges the drainage that temporarily stores water in the crushing chamber at once after crushing food waste. By storing water in the disposer 20, the food waste adhering to the crushing chamber can be removed, and by discharging it at once, the water can flow vigorously and the inside of the pipe can be cleaned. Note that the jig 60 of the present disclosure can be used regardless of the presence or absence of the disposer 20.

[0022] On the downstream side in the drainage direction of the disposer 20, a drainage trap 26 for storing the sealing water W is attached. The drainage trap 26 of the present embodiment is a so-called S-shaped trap as an example. Note that the drainage trap 26 may have a structure other than the S-shaped trap.

[0023] A drainage joint 38 is connected to the downstream side in the drainage direction of the drainage trap 26 (downstream side of the sealing water W), and a drain pipe 32 for flowing the drainage downward is connected to the downstream side in the drainage direction of the drainage joint 38.

[0024] A siphon drain pipe 44 is connected to the downstream side in the drainage direction of the drain pipe 32. The siphon drain pipe 44 includes a horizontal pipe 46 extending horizontally along the floor slab 12, and a vertical pipe 48 provided on the downstream side of the horizontal pipe 46 and extending downward along the drain riser 16. The vertical pipe 48 is connected to the drain riser 16 via a drainage joint 18.

[0025] In this siphon drain pipe 44, a siphon force is generated by flowing the drainage flowing into the vertical pipe 48 from the horizontal pipe 46 downward. The drainage in the pipes upstream of the vertical pipe 48, that is, the horizontal pipe 46, the drain pipe 32, and the confluence pipe 42 is pulled by the siphon force generated in the vertical pipe 48, and a siphon force acting in the discharge direction acts. Note that the jig 60 of the present disclosure can be used regardless of the presence or absence of the siphon drain pipe 44.

[0026] <Cleaning joint> A cleaning joint 50 is connected to the horizontal pipe 46. The cleaning joint 50 is disposed, for example, in an MB (meter box) installed in the common part of an apartment building or below the floor inspection opening in the proprietary part. The cleaning joint 50 includes a horizontal part 52 connected to the horizontal pipe 46 and a branch part 54. The horizontal part 52 is a part along the horizontal direction in the use posture, and the branch part 54 is connected upward to the horizontal part 52 and is a part whose axial direction is along the vertical direction.

[0027] As shown in FIG. 2, the branch portion 54 includes a connection portion 54A connected to the horizontal drawing portion 52 and a diameter-expanded portion 54B that is formed in a cylindrical shape with an expanded diameter above the connection portion 54A. Further, as shown in FIG. 3A, a step S is formed at the lower end portion of the diameter-expanded portion 54B and protrudes inward of the diameter-expanded portion 54B. In other words, a step S is formed between the connection portion 54A and the diameter-expanded portion 54B.

[0028] As shown by the two-dot chain line, a horizontal drawing pipe 46 is connected to the horizontal drawing portion 52. Thereby, the horizontal drawing pipe 46 and the cleaning joint 50 are integrated. Note that appropriate water-stopping treatment is performed between the horizontal drawing pipe 46 and the cleaning joint 50.

[0029] Note that the "horizontal drawing pipe" in the present disclosure is a concept including the horizontal drawing portion 52 of the cleaning joint 50. Further, the "branch pipe" in the present disclosure is a concept including the branch portion 54 of the cleaning joint 50. The "horizontal drawing pipe" and the "branch pipe" in the present disclosure may be formed by other components than the cleaning joint 50. For example, a vertical pipe as a branch pipe may be directly connected to the horizontal drawing pipe 46 (the branch pipe is connected upward).

[0030] <Fixture> The fixture 60 of the present disclosure is used by being attached to the open end of the diameter-expanded portion 54B in the cleaning joint 50 when cleaning the horizontal drawing pipe 46.

[0031] Note that in normal times when the fixture 60 is not used, a lid member (not shown) is screwed and fixed to the male screw 56 formed on the outside of the diameter-expanded portion 54B. A packing 58 surrounding the diameter-expanded portion 54B is provided below the male screw 56.

[0032] The fixture 60 includes a lid 62 and a guiding portion 64. Among these, the lid 62 is a columnar sealing member capable of sealing the open end of the branch portion 54 connected upward to the horizontal drawing portion 52. The lid 62 is disposed on the upper surface of the step S formed to protrude inward of the branch portion 54. At this time, the bottom surface 62A of the lid 62 is in contact with the step S and is disposed. Thereby, the open end of the branch portion 54 is sealed. Note that a packing (not shown) or the like may be disposed between the step S and the bottom surface 62A.

[0033] The guiding portion 64 is a tube body P insertion direction regulating portion for guiding the tube body P into the horizontal drawing tube 46. The guiding portion 64 is formed with a protruding portion 64A and a through hole 64B. The protruding portion 64A is a columnar member protruding obliquely upward of the lid 62. The protruding portion 64A is inclined at an angle θ1 with respect to the vertical direction (up and down direction) in the use posture. In other words, the protruding portion 64A is inclined at an angle θ1 with respect to the axial direction of the branch portion 54 in the use posture.

[0034] The through hole 64B is a hole penetrating through the guiding portion 64 and the lid 62. The upper portion of the through hole 64B is formed along the guiding portion 64 and is inclined at an angle θ1 with respect to the vertical direction. Also, as shown in FIG. 3B, the lower portion of the through hole 64B has an enlarged diameter along the outer shape of the lid 62.

[0035] Also, a regulating portion 66 is provided inside the lid 62, that is, on a part of the inner peripheral wall of the through hole 64B. The regulating portion 66 is formed on the upper inner peripheral wall of the portion where the lid 62 penetrates through the through hole 64B, and is a protrusion curved so that at least a part thereof protrudes downward.

[0036] An extension line 66E obtained by extending while maintaining the curvature of the regulating portion 66 is arranged at a position where it does not interfere with the boundary portion (in other words, the corner portion between the upper surface of the horizontal drawing portion 52 and the side surface of the branch portion 54) 50E of the horizontal drawing portion 52 and the branch portion 54. Also, the extension line 66E is arranged below the boundary portion 50E.

[0037] When the tube body P is inserted into this lid 62, as shown in FIG. 4, the tube body P is inserted along the inclination angle θ1 of the through hole 64B. Also, the insertion direction of the tube body P is regulated by the regulating portion 66, and it is guided to a position where it does not interfere with the boundary portion 50E of the horizontal drawing portion 52 and the branch portion 54.

[0038] <Function and Effect> When the jig 60 of the present disclosure is used, the open end of the branch portion 54 connected upward to the lateral pulling portion 52 of the cleaning joint 50 is sealed by the lid 62. And a through hole 64B through which the pipe body P can be inserted is formed in this lid 62.

[0039] Since the through hole 64B is formed in the lid 62 that seals the open end, the cross-sectional area of the through hole 64B is smaller than the cross-sectional area of the open end of the branch portion 54. Thereby, when a pipe body is inserted into the lateral pulling pipe 46 and the inside of the pipe is cleaned, compared with the case where the jig 60 is not used, the cleaning water discharged from the pipe body is less likely to overflow.

[0040] In particular, when cleaning the inside of the pipe on the kitchen sink 19 side shown in FIG. 1, that is, the upstream side, it is possible to suppress the cleaning water after cleaning from overflowing from the open end of the branch portion 54 when passing through the cleaning joint 50 on the relatively downstream side.

[0041] Also, the through hole 64B is inclined with respect to the vertical direction. For this reason, the pipe body P is guided into the lateral pulling pipe 46 at an angle inclined with respect to the vertical direction. Thereby, compared with the case where the pipe body P is inserted along the vertical direction, it is easier to guide the pipe body P into the lateral pulling pipe 46. Similarly, the operation is easy when pulling out the pipe body P from the lateral pulling pipe 46.

[0042] In addition, in a simple cylindrical jig in which the guiding portion 64 is not formed, such as the jig 100 according to the comparative example shown in FIG. 7, since the opening area is large, in order to suppress the overflow of the cleaning water, a method of increasing the height of the jig 100 itself can be considered.

[0043] However, in such a method, the angle θ2 of the pipe body P with respect to the vertical direction is likely to be smaller than the angle θ1 of the pipe body P in the present disclosure, and it is difficult to guide the pipe body P into the lateral pulling pipe 46.

[0044] Also, in the jig 60 of the present disclosure, the bottom surface 62A of the lid 62 contacts the upper surface of the step S of the branch portion 54 of the cleaning joint 50, and the open end of the branch portion 54 is sealed. That is, the open end is sealed by placing the lid 62 on the step S.

[0045] Accordingly, for example, compared with the case of using a jig for screwing a member into the male screw 56 of the branch portion 54 to seal the open end, the jig 60 is easy to manufacture. Further, when cleaning the downstream side and the upstream side of the lateral drawing pipe 46, the insertion direction of the pipe body P can be easily changed only by changing the installation direction of the jig 60.

[0046] Further, in the jig 60 of the present disclosure, a restricting portion 66 for guiding the pipe body P is provided on the inner peripheral wall of the through hole 64B at a position that does not interfere with the boundary portion 50E between the lateral drawing portion 52 and the branch portion. Thereby, when the pipe body P is inserted into the through hole 64B, the tip of the pipe body P is hardly caught by the boundary portion 50E. For this reason, it is easy to guide the pipe body P into the lateral drawing pipe 46.

[0047] <Modification example> In the above embodiment, the lower portion of the through hole 64B is expanded in diameter along the outer shape of the through hole 64B, and the restricting portion 66 is provided on a part of the inner peripheral wall of the through hole 64B. However, the embodiment of the present disclosure is not limited to this.

[0048] For example, as shown in FIGS. 5A and 5B, the entire through hole 64B may have a shape along a straight line. In this case, it is preferable that the extension line 64E obtained by extending the inner wall surface at the uppermost part of the through hole 64B is arranged at a position that does not interfere with the boundary portion 50E between the lateral drawing portion 52 and the branch portion 54. In other words, the extension line 64E is preferably arranged below the boundary portion 50E.

[0049] That is, as shown in FIG. 6, the inclination angle θ1 of the through hole 64B is preferably formed at an angle that guides the pipe body P inserted into the through hole 64B to a position that does not interfere with the boundary portion 50E between the lateral drawing portion 52 and the branch portion 54.

[0050] Even if the jig 60 is formed in this manner, when the tubular body P is inserted into the through-hole 64B, an effect of making it difficult for the tip of the tubular body P to be caught by the boundary portion 50E can be obtained. As a result, it is easy to guide the tubular body P into the lateral drawing pipe 46. Further, since the lower portion of the through-hole 64B is not enlarged in diameter, it is difficult for the cleaning water to enter the inside of the through-hole 64B. Thereby, the effect that the cleaning water discharged from the tubular body P is less likely to overflow is further enhanced.

[0051] In addition, when the entire through-hole 64B has a shape along a straight line, an extension line 64E obtained by extending the inner wall surface at the uppermost part of the through-hole 64B may interfere with the boundary portion 50E of the lateral drawing portion 52 and the branch portion 54.

[0052] In this case, by making the diameter of the tubular body P smaller than the cross-sectional area of the through-hole 64B, it is possible to make it difficult for the tip of the tubular body P to be caught by the boundary portion 50E. Thus, the present disclosure can be implemented in various modes.
