DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a remotely operated valve opening / closing device for a drainage device used for a washbasin, a sink of a sink, and the like.

[0002]

2. Description of the Related Art Conventionally, as a drainer used for a home wash bowl, a sink of a sink, or the like, there is known a drainer capable of remotely opening and closing a valve element of the drainer as shown in FIG. Have been.

A drainer employing the remote-operated valve opening / closing device shown in FIG. 5 includes a drainer main body having a drain port and a branch pipe, a valve body for opening and closing the drain port and moving up and down. A wire portion and a release wire composed of a sheath tube surrounding the wire portion so as to be able to advance and retreat, and a switch portion operating to advance and retreat the wire portion of the release wire connected to one end of the release wire; Further, a lifting / lowering member connected to the other end of the wire portion and having a distal end portion for moving up and down freely in the branch pipe in conjunction with the wire portion of the release wire and abutting on the valve body to raise and lower the valve body. And an O-shaped packing (hereinafter, referred to as an “O-ring”) provided on the peripheral edge of the elevating member and abutting on the inner surface of the branch pipe. In the drainage device employing the remote control valve opening and closing device shown in FIG. 5, when the switch portion is operated to move the wire portion of the release wire forward and backward, the distal end portion of the lifting member which operates in conjunction with the wire portion is operated. However, since the valve body in contact with this is raised and lowered, the drain port can be remotely opened and closed.

[0004]

However, because of the structure of the remote control valve opening / closing device employed in the drainage device shown in FIG. There was a new problem that did not exist, as described below.

In the drainage device shown in FIG. 5, drainage naturally flows through the inside of the drainage device for the purpose of use. It is, of course, very inconvenient for these drains to leak out of the drainer.However, in a drainer employing a remote-operated valve opening and closing device as described above, the release wire extends outside the drainer body. Therefore, it is necessary to provide a hole for extending the release wire on the outer wall of the drainer body, and there is a possibility that water leaks from this hole. In addition, the wire portion of the release wire is usually made of braided thin steel in order to ensure flexibility for bending. When touching the wire portion, the wire portion is rusted and deteriorated, and in the worst case, the wire portion may be broken.

For this reason, in the remote-operated valve opening / closing device employed in the drainage device shown in FIG. 5, an O-ring for stopping water is arranged around the periphery of the elevating member, and abuts against the inner surface of the branch pipe. To prevent the drainage from moving from the contact surface of the O-ring,
Water is prevented from leaking from the extension hole or the like of the release wire, or the wire portion is prevented from touching the drainage.

However, the drainer body is usually formed of a resin that is not very smooth. Therefore, when the O-ring is provided around the elevating member as described above,
The ring comes into contact with the surface of the resin that is not very smooth, so that the wire portion of the release wire does not work smoothly, and the O-ring is easily worn due to friction, causing water leakage. In order to solve the friction problem, there is a method of applying a lubricant such as silicone grease to the O-ring. However, since the number of work steps required in the production of the drainage device increases, it becomes impossible to provide a product at a low cost and a wire portion is not provided. Since the lubricant is consumed during the forward and backward movement of the wire, the forward and backward movement of the wire portion does not work smoothly, and the O-ring is also worn. In addition, the resin material is likely to be distorted due to heat shrinkage during molding or slight stress during use, and water may leak from gaps caused by the distortion. If the drainer body is made of metal in order to solve these problems, the cost of raw materials is higher than that of resin, and there arises a problem that processing requires a technique. In particular, the inner surface of a pipe such as the inside of a branch pipe is difficult to polish to smooth the surface, and it is extremely difficult to ensure the accuracy enough to secure water stoppage. As described above, the remote-operated valve opening / closing device for the drainage device using the elevating member shown in FIG. 5 has a remarkable problem in waterproofness, durability, and operability. The present invention has been made to solve the above problems.
