Japanese Patent No. 36333336

As described in paragraph 0003, in the drainage pipe adopting the remote-operated drain plug device described in Patent Document 1, the bathtub is placed on the bathtub pan, and the cover member is connected to the pipe from the bathtub. After making it impossible to remove the cover member from the upper drain, insert the release wire almost vertically from the upper surface of the cover member, and push the tip of the release wire to the position below the drain outlet that fixes the release wire end. Must be moved. However, because the release wire is inserted from above, it has been impossible to control which direction the release wire inserted into the drainage device bends after reaching the bottom surface of the drainage device. If you can remove the cover member and touch the release wire, the work will be easier, but in fact, as described above, the bathtub and its piping are placed and connected, so you can not remove the cover member. In order to arrange the release wire in an appropriate direction, there is only a method for repeatedly putting the release wire in and out until it happens to be in the direction of the drain port, which is very inconvenient.
If the insertion direction of the release wire is inserted from an oblique direction rather than the vertical direction, the direction can be slightly adjusted, but even in this case, the operation transmission member is moved downward by gravity due to the insertion from above. You may bend and not go in the direction you thought. In addition, the direction in which the release wire is inserted from the insertion opening does not necessarily coincide with the location (fixing portion) where the release wire is fixed, and even if the release wire is inserted from an oblique direction, the direction toward the fixing portion is also used. It was difficult to insert the release wire.
Although the remote-operated drain plug device described in Patent Document 1 is an example related to a drain pipe in a bathroom, the above-mentioned problem is a problem that also occurs in a remotely-operated drain plug device used for a washstand, for example. . In the case of a remote-operated drain plug device used for the drainage pipe of a wash basin, there are many cases where the release wire is passed from the side or from the bottom instead of the top surface. Since the release wire is disposed so as to hang inside, there is a problem that the storage property of the cabinet is deteriorated. In addition, the user of the washstand may get injured by touching the release wire, or the release wire may be damaged. However, when the release wire is inserted from the upper surface of the drainage device, it is very difficult to guide the release wire to the drain outlet as in the invention of Patent Document 1.

The lock shaft 15b is configured to retreat back and forth alternately toward the operation unit 11 side. Note that the lock mechanism 15 is conventionally well-known under the name of, for example, a thrust lock mechanism, and the details are not described. Similarly, only the position where the lock mechanism 15 is disposed is shown, and the detailed internal configuration is not shown.
The guide tube 7 is a tube tube made of polyvinyl chloride or the like having flexibility in the lateral direction and rigidity in the axial direction, one end being the insertion tube 6b of the cover member 6, and the other end being the operation portion 11. At the time of construction, the release wire 10 inserted from the operation unit 11 is guided to the insertion port 5 of the insertion port 5 at the time of construction.

The drainage pipe of the bathroom of this embodiment configured as described above is constructed in the bathroom as follows. In addition, even when it does not elaborate in detail, the connection location of each member is watertightly connected using adhesion | attachment, packing, etc. as needed.
First, at a factory or the like, the cover member 6 is watertightly connected to the drainage body 4a by bonding or the like. Further, the discharge port 4 c of the drainage device 4 is connected to the branch pipe portion 14 b of the washing place trap 14. Further, one end of the guide tube 7 is connected to the insertion tube 6 b of the cover member 6.
After connecting each member as described above, the following construction work is performed at the construction site.
At the construction site, the trap outlet 14c of the washing place trap 14 is connected to an underfloor pipe connected to the sewage side, and then the washing place trap 14 is attached to the washing place pan attachment opening U1, and the washing place drain 1a is placed on the washing place. Deploy.
Next, the male screw portion of the flange member 12 is inserted into the bathtub pan mounting port P1, and the female screw of the drainage device 4 and the male screw of the flange member 12 are screwed together. Thus, the peripheral edge of the bathtub pan attachment port P1 is sandwiched between the flange portion 12a and the upper edge of the drainage device 4, and the drainage device 4 is connected and fixed to the bathtub pan P.
Next, the tubular portion of the drain outlet main body 1 is inserted into the bathtub mounting port B1 from above so that the lower surface of the flange 1b comes into contact with the peripheral edge of the bathtub mounting port B1.
Next, the female screw of the bathtub joint 13 is screwed into the male screw of the drain port body 1. Accordingly, the peripheral edge of the bathtub attachment port B1 is sandwiched between the flange 1b and the upper edge of the bathtub joint 13, and the drain port body 1 and the bathtub joint 13 are connected and fixed to the bathtub B.
Next, the bathtub B is placed on the bathtub pan P, and the connection packing 13 c of the bathtub joint 13 is brought into contact with the upper surface of the cover member 6 so as to cover the bathtub inlet 6 a of the cover member 6.
Thereby, the waste_water | drain from the bathtub coupling 13 is comprised so that it may flow in in the drainage device 4 from the bathtub inflow port 6a. That is, the connection packing 13 c of the bathtub joint 13 is connected to the bathtub inlet 6 a on the cover member 6.
At this time, in order to pull up the release wire 10 from the bathtub inlet 6a, the position of the bathtub B is adjusted and arranged so that the drain port 1a is placed and fixed on the bathtub inlet 6a of the cover member 6. Since the connection between the bathtub joint 13 and the cover member 6 is such that the connection packing 13c is in contact with the upper surface of the cover member 6, the connection can be made with some adjustment in the horizontal direction.
As described above, when the bathtub B is placed on the bathtub pan P, the bathtub B is not necessarily “fixed” to the bathtub pan P with a screw or the like, but is moved for work by being positioned for piping. In addition, since the periphery is watertightly attached with a caulking agent or the like, it is in a “fixed” state in which it does not practically move.
As a result of placing the bathtub B on the bathtub pan P in this way, the positions of the drain outlet 1a and the bathtub inlet 6a of the drainage device 4 in a plan view are substantially matched. Thereby, the guide part 4b comprised so that the release wire 10 may be guided toward the bathtub inflow port 6a may guide the release wire 10 toward the connection part 8 which is a fixing part provided in the drain port 1a. The guide portion 4b is configured as follows.

The inserted release wire 10 passes through the guide tube 7, the insertion port 5, and the insertion tube 6 b from the operation unit 11, and passes through the groove of the guide unit 4 b from the guide unit 4 b located immediately below the insertion port 5. It reaches the position below the drain port 1a.
From this state, a jig such as a long-nose pliers is inserted into the drain port 1a, and the end of the release wire 10 is pulled up into the bathtub inlet 6a and / or the drain port 1a (insertion of the release wire 10 is not completed). Therefore, although the end of the release wire 10 reaches the bathtub inlet 6a, it may not reach the drain 1a).
Further, when the release wire 10 is pushed in and the lock mechanism 15 at the end of the release wire 10 is arranged in the operation unit main body 11a, the end of the release wire 10 reaches the upper end of the drain port main body 1, and therefore the release wire 10 is attached to the support member 9. The end portion of the outer tube 10 a is connected and fixed, and the support member 9 is connected and fixed to the connection portion 8 in the drain port body 1, thereby fixing the end portion of the release wire 10 inside the drain port body 1.
Further, the distal end of the valve shaft 3 is fitted and connected to the valve member 2 to complete the construction of the drainage pipe in the bathroom of this embodiment.

  In the drainage pipe of the bathroom of this embodiment configured as described above, when the operation unit 11 is operated and the inner wire 10b is advanced to the valve member 2 side by the lock mechanism 15 and fixed, the valve member 2 becomes the valve shaft. 3 is fixed in a state of being pushed up, and the drain port 1a is opened. Further, when the operation unit 11 is operated to release the lock mechanism 15 and the inner wire 10b is retracted to the operation unit 11 side by the action of the return spring, the valve member 2 is also lowered, and the valve member 2 is discharged to the drain port. The drain port 1a is closed by covering 1a.

Moreover, in the drainage pipe of the bathroom of the conventional example configured as described above, the drainage port 1a is opened with the water discharge or drainage accumulated in the bathtub B, or the water discharge or the drainage port 1a is opened. When drainage occurs, the discharged water or drainage passes from the drain outlet body 1 through the bathtub joint 13 and the bathtub inlet 6a of the cover member 6, and is connected to the drain 4, the outlet 4c, the branch pipe portion 14b, the washing trap 14, And finally discharged from the trap outlet 14c of the washing place trap 14 to the sewage side through the underfloor piping.
Further, when drainage is generated on the bathtub pan P, the drainage passes through the bathtub joint 13 and the bathtub inlet 6a of the cover member 6 from the bathtub pan outlet 13b, and the drainage unit 4, the discharge port 4c, and the branch pipe part. 14b and the washing place trap 14 are discharged from the trap outlet 14c of the final washing place trap 14 to the sewage side through the underfloor piping.
In addition, when wastewater is generated on the washing place pan U, the wastewater is discharged from the washing place pan drain port 14a through the washing place trap 14 and from the trap outlet 14c of the washing place trap 14 to the sewage side through the underfloor pipe.
Moreover, when performing these drainage, the sealed water which is a waste water storage part arises from the inside of the drainage device 4 through the discharge port 4c and the branch pipe part 14b in the washing place trap 14.
