Japanese Patent Laid-Open No. 10-168773 JP-A-2002-88553

In the remote-operated drain plug device shown in FIG. 14, the release wire is fixed by the holder portion provided to the elbow member, so that the height position of the release wire is fixed. Since the height of the release wire also changes as the valve moves back and forth, the valve body may not move up to the specified height, and further, the valve body may not be lowered by the specified size and may not be seated on the drain plug. Such a remote-operated drain plug device has a problem in that the drainage flow rate is deteriorated or the water stop is poor because the valve body does not move to a predetermined height.
In addition, the remote-controlled drain plug device of the conventional example has a malfunction due to the inner wire being pulled out from the outer tube attached to the elbow member with a pliers or the like and bent into the bearing portion of the wire receiving portion. It was necessary to insert an inner wire that would easily fall into the wall, and such an operation with high precision had to be performed on a narrow bathtub, and the workability was poor.
Further, since the remote-operated drain plug device shown in FIG. 15 can fix the release wire to the wire receiving portion that is attached to the drain plug, and can cope with variations in the thickness of the bathtub, Since the release wire was inserted from the drain, the release wire was pulled up from the drain outlet and connected to the wire receiving portion, and the wire receiving portion had to be attached to the drain plug, so the workability was poor.

In this state, when an operation is applied to the operation unit 5, the inner wire 61 of the release wire 6 communicating with the operation unit 5 moves forward, pushes up the valve body 4 attached to the tip of the release wire 6, and the valve body 4 Is separated from the drain plug 3. At this time, the thrust lock mechanism of the operation unit is activated to lock the progress of the inner wire 61, so that the valve body 4 is kept raised. Thus, the drainage in the bathtub is drained from the drain plug 3.
The drainage drained from the drain plug 3 flows into the elbow member 9 from the inlet 91 of the elbow member 9 and drains downstream from the outlet 92 of the elbow member 9. The drainage is finally drained into a sewer pipe through a drain trap.
When the operation unit 5 is operated again from this state, the inner wire 61 advances a little, and the thrust lock mechanism of the operation unit 5 is activated. Then, the lock of the thrust lock mechanism is released, and the inner wire 61 moves backward due to the repulsive force of the return spring set on the inner wire 61, so that the valve body 4 attached to the rod portion 63 at the tip of the inner wire 61. Is lowered so as to be pulled in accordance with the retreat of the inner wire 61. When the valve body 4 is lowered and seated on the drain plug 3, the drain plug 3 is closed, so that the waste water is stored in the tank body 1.
Thereafter, by repeating this operation of the operation section 5, the valve body 4 moves up and down, and the drainage is drained / stored in accordance with the vertical movement of the valve body 4.

Although the present embodiment has been described as described above, the present invention is not limited to the above-described embodiment, and the design can be changed as appropriate without departing from the content described in the claims.
For example, as shown in FIG. 13, the elbow member 9 may not be configured with the holder portion 8, but may be configured with a tubular connection pipe 10 connected to the lower end of the drain plug 3. In this case, the release wire insertion hole 93 is also formed on the side surface of the connection pipe 10.
