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. Also, there are a lot of work to be done at the construction site, and the worker must work in a narrow bathroom etc., and when the release wire is inserted from the operation part, the release wire is bent to make it malfunction. There was a high probability.

The remote-controlled drain plug device of the present invention is
1. Remote control drain plug device with good workability.
2. A remote-operated drain plug device that prevents the release wire from malfunctioning during construction.
3. It must be a remote-operated drain plug that does not cause poor seating of the valve body.
It was invented to solve the problem.

The present invention according to claim 1 is provided in a tank body 1 having a drainage port 2 opened on the bottom surface, a drainage plug 3 attached to the drainage port 2, and the drainage plug 3.

Therefore, the drainage from the drainage port 2 can be discharged in the direction of the sewer pipe disposed laterally with respect to the drainage port 2.
According to a fourth aspect of the present invention, the member disposed below the drain plug 3 has an inlet 101 through which drainage flows, an outlet through which drainage is discharged, and a release wire insertion hole through which the release wire 6 is inserted. Therefore, the drainage from the drainage port 2 can be discharged in the direction of the sewer pipe disposed below the drainage port 2.
According to the fifth aspect of the present invention, since the lifting body 11 made of a soft material is detachable at the end of the release wire 6, a small drain plug 3 is formed from the upper part of the tank body 1 at the construction site. Since the release wire 6 can be easily pulled up from the inside, the workability is further improved.
According to the present invention of claim 6, in the remote-operated drain plug device, the release wire 6 is previously attached to the holder portion 8 at a factory or the like, and the wire receiving portion 7 is attached to the drain plug 3, At the construction site, the drain plug 3 is attached to a member disposed below the drain plug 3, and then the release wire 6 is pulled up from above the drain plug 3 and the release wire 6 is attached to the wire receiving portion 7 to complete the construction. Since the construction method of the remote-operated drain plug device is such that the release wire 6 is attached to a member disposed below the drain plug 3 in advance in a factory or the like, so that the release wire 6 can be inserted in a narrow site. It became unnecessary to do.

From this state, as shown in FIG. 12, a small drainage port 2 is obtained by putting pliers or fingers into the drainage port 2 from above the drainage plug 3 and pulling up the lifting body 11 attached to the tip of the release wire 6. Can be easily removed from The lifting body 11 is removed from the distal end of the release wire 6 pulled up by the lifting body 11, and the leading end of the release wire is connected to the bearing portion 72 of the wire receiving portion 7 as shown in FIG. Attach to 3. Then, the valve body 4 is detachably attached to the tip of the release wire 6 as shown in FIG. 5, thereby completing the construction of the remote-operated drain plug device as shown in FIG. 6.

The remote-operated drain plug device configured as described above has the following operation and drainage flow.
When drainage is stored in the bathtub, the valve body 4 of the drain outlet 2 is seated on the drain plug 3. 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.
