[0002]

2. Description of the Related Art Conventionally, drainage structures such as bathtubs, washbasins, sinks, and handwashers provided with a drainage tap remotely operated by an operation unit connect a drainage pipe joint to a drainage port of the water tank, and connect the drainage pipe joint to the drainage pipe joint. And a drain pipe is connected to it. In the case of a basin, a sink, a hand-washing device, etc., as shown in FIG.
A drainage pipe joint 102 is connected to a drainage port 101, and a drainage trap 103 is arranged in the drainage pipe joint 102.

[0003]

However, the wastewater from the bathtub is drained to a collective trap shared with the wastewater from the washing place. However, the odor of the sealed water from the collective trap passes through the drainpipe to drain the bathtub. There is a danger of backflow inside.

In a basin, a sink, a hand-washing machine, etc., the space inside the cabinet and the space below the water tub 100 is blocked by a drain pipe joint 102 and a drain trap 103 located immediately below the water tub 100, so that the storage space is limited. It is poorly used as a storeroom. Moreover, in such a piping structure,
The number of parts, such as various pipes for forming the drain pipe joint 102 and the drain trap 103, will inevitably increase. In addition, these piping operations are very difficult in a small space in the cabinet because of many connecting points.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to prevent the backflow of odor in a bathtub by using a drain pipe joint itself as a drain trap. In addition, for water tanks such as washbasins, sinks, and handwashers, which are compatible with remote-operated drainage faucets, the space inside the cabinet that supports the water tank and the bottom of the water tank that is supported on the wall of the frame An object of the present invention is to provide a drainage pipe joint for an aquarium that can be used as a storage space without waste and that can be used for a remotely operated type drain plug. Another object is for a water tank that can prevent the ingress of drainage into the guide tube of a remote-operated drainage faucet placed in the bathtub to prevent corrosion of the release wire and leakage from the connection part of the guide tube. To provide a drain connection.

[0006]

In order to achieve the above-mentioned object, the present invention provides a technical means including a drainage port of a water tank provided with a drainage plug remotely controlled by an operation unit and a drainage joint connected to a drainage pipe. A drain pipe directly connected to the drain port, and a riser pipe part connected upward from the lower end of the vertical pipe section and connected to the drain pipe constitute a drain trap, and the peripheral surface has the drain trap. An insertion hole for a release wire that connects the drain plug and the operation unit is provided. (Claim 1)

According to the above technical means, the following functions and effects can be obtained. A drain connection connected to the drain constitutes a drain trap. Further, by providing the insertion hole, it is possible to insert a release wire connecting the operation unit and the drain plug. Therefore, in the bathtub, it is possible to prevent the backflow of the odor while supporting the remote-operated drain plug.

In the case of a basin, a sink, a hand-washing device, etc., since the drain trap is close to the bottom of the water tank, a large space can be formed directly under the water tank. Can be used effectively. or,
Since the drainage pipe joint itself is a drainage trap, the number of parts of the drainage pipe can be reduced, and the piping work for forming the trap can be omitted. The piping work is very simple.

The water tub is a bath tub, and the insertion hole is provided in a vertical pipe portion at a position higher than a water sealing surface of the drain trap. The insertion hole is connected to a guide tube for guiding and protecting a release wire. The following functions and effects can be obtained by also using the unit. (Claim 2) Water is always present in the drain trap, but since the insertion hole is located above the water sealing surface, water does not enter the guide tube. Therefore, since water does not stay in the guide tube, corrosion of the release wire and leakage of water from the connection portion of the guide tube can be prevented.

The following operational effects can be obtained by providing a plurality of the insertion holes. Since the introduction port of the release wire can be selected from a plurality of insertion holes, the degree of freedom of the mounting position of the operation unit is increased, and the holes other than the one through which the release wire is inserted can be used, for example, as an intake hole for overflow water from a bathtub. . Unused holes among the plurality of insertion holes are closed with a lid or the like.
