  In the cleaning methods disclosed in Patent Documents 1 and 2, the cleaning tube is provided in the horizontal tube regardless of whether the balloon or elastic member of the cleaning tool is inserted into the horizontal tube or the cleaning hose of the high-pressure cleaner is inserted. It is carried out by inserting them from the cleaning port. However, for example, the washing hose of a high-pressure washing machine is moved upstream in the horizontal pipe while the pressurized water is jetted back from the nozzle tip, and the urinary stones and other deposits that fall off are upstream of the cleaning port direction. Used to be collected. Therefore, it is necessary to supply the water again from the upstream side after the inside of the horizontal pipe is washed with high pressure and to flow the peeled-off deposits to the downstream drainage pipe. In addition, since the reverse injection direction is on the upstream side, workability when the cleaning hose is moved in the horizontal pipe is poor.

  In addition, when it is difficult to use the cleaning port provided in the uppermost stream, a horizontal pipe is cut halfway and a joint having a cleaning port is newly installed. If this means is used, a new cleaning port can be provided near the downstream side of the horizontal pipe, but operations such as cutting the horizontal pipe and connecting joints are very troublesome. In addition, when a joint is newly provided, a step always occurs at the joint between the horizontal pipe and the joint, and hair, dust, and the like easily accumulate on the step. As the joint is provided further downstream, that is, closer to the drainage standpipe, the amount of dust and the like that flows is increased, and the accumulation thereof is also noticeable.

  The present invention has been made in view of the above, and can be easily provided at a desired position of a drain pipe of a drain pipe system with a simple configuration, and drain pipe cleaning that does not cause accumulation of dust and the like. It is an object of the present invention to provide a drainage pipe cleaning method using the attachment and the drainage pipe cleaning attachment.

In order to solve the above problems, the attachment for cleaning a drain pipe of the present invention is:
An annular portion having a communication hole in the peripheral wall portion and a seal member provided at least around the communication hole on the inner peripheral surface;
It projects obliquely outward from the periphery of the communication hole in the peripheral wall portion of the annular portion, and is integrated with a guide tube portion used for insertion of a drain pipe cleaning tool,
The through hole formed in the horizontal pipe of the drain pipe system is positioned so that the communication hole communicates, and the annular portion is attached in close contact with the outer surface of the horizontal pipe. .

The annular part is formed in a substantially circular cross-section covering all of the circumferential direction of the outer surface of the horizontal pipe, and is divided into two along the axial direction, each divided annular part is connected, It can be set as the structure with which the said horizontal draw pipe is mounted | worn.
Further, the annular portion is formed in a substantially arc-shaped cross-section that covers a part of the outer surface of the horizontal pipe in the circumferential direction, and is configured to be expanded and contracted according to the outer diameter of the horizontal pipe. it can.

Moreover, the drain pipe cleaning method of the present invention comprises:
An annular portion having a communication hole in the peripheral wall portion and having a seal member provided at least around the communication hole on the inner peripheral surface, and projecting obliquely outward from the periphery of the communication hole in the peripheral wall portion of the annular portion. Drain pipe cleaning attachment that is integrated with the guide tube
The through hole formed in the horizontal pipe is aligned so that the communication hole communicates, and the annular portion is closely attached to the outer surface of the horizontal pipe,
A drain pipe cleaning tool is inserted from the guide tube portion, and the inside of the horizontal pipe is cleaned through the communication hole and the through hole.

The annular portion is formed in a substantially circular cross-section covering the entire circumferential direction of the outer surface of the urinal drain pipe, and is divided into two along the axial direction, each divided into the outer surface of the horizontal pipe It can be set as the structure which has the process of arrange | positioning and connecting so that an annular part may face each other.
Further, the annular portion is formed in a substantially arc-shaped cross-section covering a part of the outer surface of the horizontal pipe, and is expanded or contracted according to the outer diameter of the horizontal pipe to It can be set as the structure which has the process to mount | wear.

  Further, in the drain pipe cleaning method of the present invention, the drain pipe cleaning attachment is attached so that the guide cylinder portion is inclined downstream along the axial direction of the horizontal pipe, and the drain pipe cleaning tool is attached. It is preferable that the guide tube is inserted into the horizontal draw tube and moved in the upstream direction in the horizontal draw tube.

  The drain pipe cleaning attachment of the present invention has a communication hole in the peripheral wall portion of the annular portion, and a seal member is provided around the communication hole on the inner peripheral surface thereof. Accordingly, if the annular portion is attached to the through hole formed in the tube wall portion of the horizontal draw pipe with the communication hole being aligned, the seal member communicates with the periphery of the through hole and the communication hole in close contact with each other. Since the guide tube part is integrally provided in the communication hole, if the drain pipe cleaning tool is inserted from the guide cylinder part, the drain pipe cleaning tool can be easily inserted into the horizontal pipe through the communication hole and the through hole. Inserted. That is, if the drain pipe cleaning attachment of the present invention is used, even if the through hole is formed at any position of the horizontal draw pipe, the through hole serves as an insertion port (cleaning port) for the drain pipe cleaning tool. be able to. In addition, since there is no seam as in the case of connecting the joint by cutting the middle of the horizontal draw pipe, the drain pipe cleaning attachment of the present invention becomes a new accumulation factor such as hair and dust. Nor.

  Therefore, the drainage pipe cleaning attachment of the present invention can be provided at a position closer to the drainage stack, and the high pressure washer hose is inserted from the downstream side of the horizontal pipe, and the reverse injection is used in the upstream direction. Since it can be advanced, deposits such as urine can be quickly flowed to the downstream side, that is, the drainage stack side, and the efficiency of the cleaning operation can be improved.

  Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings. Drawing 1-Drawing 5 are figures for explaining attachment 1 for drainage pipe washing concerning one embodiment of the present invention. The drain pipe cleaning attachment 1 of the present embodiment is connected to a drainage stack 3000 at the most downstream position while a sanitary instrument, particularly a urinal instrument installation pipe 2000 is connected in a drain pipe system in a building. Attached to the horizontal tube 1000 (see FIG. 5). A through hole 1100 is formed in advance in the horizontal drawing pipe 1000 where the drain pipe cleaning attachment 1 of this embodiment is attached, and near the upper part of the horizontal drawing pipe 1000.

  As shown in FIGS. 1 and 2, the drain pipe cleaning attachment 1 of the present embodiment includes an annular portion 2 and a guide tube portion 3. In the present embodiment, the annular portion 2 has an inner diameter that is substantially the same as the outer diameter of the horizontal drawing tube 1000 and has a substantially circular cross section that covers the entire circumferential direction of the outer surface of the horizontal drawing tube 1000. The annular portion 2 is divided into two divided annular portions 2a and 2b along the axial direction thereof, and a hinge portion 2c is provided on one side of a joint portion between the two divided annular portions 2a and 2b and engaged with the other. A member 2d is provided. With the engagement member 2d disengaged, the split annular portions 2a and 2b are opened around the hinge portion 2c in the direction of separating from each other. 2a and 2b can be approached again, and both can be engaged by the engaging member 2d, so that they can be mounted around the horizontal draw tube 1000 (see FIGS. 3 and 4).

  The annular portion 2 has a communication hole 22 formed through the peripheral wall portion 21. Further, on the inner peripheral surface of the annular portion 2, a seal member 23 such as rubber or synthetic resin is attached to at least the periphery of the communication hole 22, in the present embodiment, over the entire inner peripheral surface. Accordingly, the two divided annular portions 2a and 2b are opened as described above, and the communication hole 22 is closed over the horizontal drawing tube 1000 so as to match the through hole 1100 of the horizontal drawing tube 1000. When the two divided annular portions 2a and 2b are engaged, the seal member 23 is intimately fixed to the outer peripheral surface of the horizontal drawing tube 1000.

  The guide cylinder portion 3 is provided so as to protrude obliquely outward from the peripheral wall portion 21 located around the communication hole 22 of the annular portion 2, and is integrated with the annular portion 2. By attaching the communication hole 22 of the annular portion 2 to the through hole 1100 of the horizontal drawing tube 1000, the guide cylinder portion 3 communicates with the through hole 1100 via the communication hole 22. As described above, since the through hole 1100 is provided near the upper portion of the horizontal drawing tube 1000, when the annular portion 2 is attached to the through hole 1100 by aligning the communication hole 22, the guide tube portion 3 is attached. The protruding direction at the time is obliquely upward. Further, the guide tube portion 3 is inclined to one side, and a drainage pipe cleaning tool is inserted along the inclined direction. Therefore, when the annular portion 2 is provided on the downstream side of the horizontal draw pipe 1000 close to the drainage stack 3000, the guide cylinder portion 3 is attached so as to be inclined toward the downstream side. Thereby, when the drainage pipe cleaning tool is inserted, the drainage pipe cleaning tool is guided in the upstream direction in the horizontal drawing pipe 1000.

  The drain pipe cleaning attachment 1 of the present embodiment is used as follows. First, as shown in FIG.4 and FIG.5, the through-hole 1100 is opened in the appropriate position of the horizontal drawing pipe 1000 in a drain pipe system. As described above, the opening position is on the downstream side as close as possible to the drainage stack 3000 to which the horizontal draw pipe 1000 is connected, and near the upper portion of the horizontal draw pipe 1100. In the case of the horizontal draw tube 1000 for a urinal, a portion located between the appliance drain pipe 2000 and the drainage stack 3000 connected to the urinal located on the most downstream side among the plurality of adjacent urinals is preferable. (See Fig. 5).

  Next, open the split ring portions 2a and 2b constituting the ring portion 2 of the drain pipe cleaning attachment 1 around the hinge portion 2c (see FIGS. 3 and 4), and align the communication hole 22 with the through hole 1100. Then, the sealing member 23 is put in close contact with the outer peripheral surface of the horizontal drawing tube 1000, and the two divided annular portions 2a and 2b are fixed by the engaging member 2d (see FIG. 1). As a result, the hollow portion of the guide tube portion 3 communicates with the through hole 1100 of the horizontal draw tube 1000 via the communication hole 22. At this time, the guide cylinder portion 3 is attached so that the inclination direction is directed toward the downstream side.

  In a normal time when the drain pipe is not washed, it is preferable to attach a cap 31 to the open end 3a of the guide tube 3 (see FIG. 1). In the horizontal draw tube 1000 for urinals, the drainage flows below the height of the center (axial center) position along the longitudinal direction of the horizontal draw tube 1000, and the water surface of the drainage is basically this axial center. Since the guide tube portion 3 protrudes further outward from the annular portion 2, the guide tube portion 3 does not overflow. However, it is preferable to seal the open end 3a with the cap 31 in order to prevent outflow for some reason and odor.

  When cleaning the horizontal drawing tube 1000, the cap 31 is first removed. Next, for example, as shown in FIG. 5, a washing hose of a high-pressure washing machine as a drain pipe washing device is inserted into the guide tube portion 3. Since the guide tube portion 3 is inclined toward the downstream side, when the cleaning hose is inserted, the guide tube portion 3 is inserted toward the upstream side. Since the washing hose of the high-pressure washing machine reversely jets water from the nozzle, when the washing hose is inserted into the guide tube portion 3 and operated, the inside of the horizontal draw pipe 1000 is moved upstream so as to run as it is. Move. Since it goes from the downstream side to the upstream side, the deposits such as urine falling off from the inner peripheral surface of the horizontal pipe 1000 due to water pressure flow in the downstream direction as they are, and are discharged toward the drainage stack 3000. Therefore, unlike the case where a cleaning hose is inserted from the conventional upstream cleaning port, after the high-pressure cleaning, it is not necessary to reflow the deposits such as urine stones that have been peeled off, and the cleaning operation can be performed efficiently. .

  Even when a drain tube cleaning tool having a balloon is used, the drain tube cleaning tool is inserted into the horizontal drawing tube 1000 via the guide tube portion 3. At this time, since the drain pipe cleaning attachment 1 of the present embodiment is provided on the downstream side closer to the drain stack 3000 as described above, the balloon may be inflated as it is at the inserted position. In the conventional drainage pipe cleaning device inserted from the upstream cleaning port, it has been necessary to guide the balloon with the guide member and push it into the horizontal pipe so that the balloon is in the downstream position as much as possible. The use of the cleaning attachment 1 makes it easy to place the balloon. Therefore, the operation | work which inflates a balloon and attaches the inside of the horizontal drawing pipe | tube 1000 of the area upstream from it to a chemical | medical agent can also be performed rapidly.

  6 and 7 are views showing a drain pipe cleaning attachment 100 according to another embodiment of the present invention. In the present embodiment, the annular portion 120 is not substantially circular in cross section, and a part of the peripheral wall portion 121 is cut out along the axial direction. That is, it is formed in a substantially arc shape in cross section that covers a part of the outer surface of the horizontal drawing tube 1000 in the circumferential direction.

  Therefore, when mounting on the horizontal drawing tube 1000, the notch 120a is widened to cover the outer surface of the horizontal drawing tube 1000. The annular portion 120 is itself made of elastic synthetic resin or metal, and when the notch 120a is widened and put on the outer surface of the horizontal drawing tube 1000, the restoring force causes the inner peripheral surface of the annular portion 120 to be covered. It is preferable that the provided sealing member 123 is in close contact with the outer surface of the horizontal drawing tube 1000. Moreover, after attaching the annular part 120 to the horizontal drawing pipe 1000, it is preferable to fix the outer periphery with the band member 140 (see FIG. 7A). It is to be noted that the communication hole 122 is formed in the annular portion 120, and the guide tube portion 130 communicating with the communication hole 122 protrudes obliquely outward as in the above embodiment. Further, reference numeral 131 shown in FIG. 6 is a cap that closes the open end portion 130 a of the guide tube portion 130.

  Similarly to the above-described embodiment, the drain pipe cleaning attachment 100 of the present embodiment is also arranged by aligning the communication hole 122 formed in the annular portion 120 with the through hole 1100 formed in the horizontal pulling pipe 1000, and guiding it. Various drainage pipe cleaning instruments such as a cleaning hose and a balloon of a high-pressure cleaning machine are inserted from the cylindrical portion 130 and used. At this time, it is preferable that the through hole 1100 is formed and mounted at a position closer to the downstream side of the horizontal drawing tube 1000 as in the above embodiment.

  In addition, the drain pipe cleaning attachment 100 of the present embodiment has a notch 120a, and is configured to expand the notch 120a and attach it to the horizontal draw pipe 1000. Therefore, an annular portion is formed according to the outer diameter of the horizontal draw pipe 1000. 120 is enlarged or reduced. Therefore, as shown in FIGS. 7B and 7C, it is possible to attach to the horizontal drawing tube 1000 having different outer diameters. In this case, since the annular portion 120 has elasticity as described above, it can be easily placed in close contact with the outer surface of the various horizontal pipes 1000 by the action of its restoring force.
