DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping system having a piping joint unit having a water supply / drainage connection.

[0002]

2. Description of the Related Art Conventionally, water supply and drainage are installed independently of each other, and a piping design has been made by a water supply / drainage facility designer in consideration of water supply capacity and drainage capacity. Conventionally, Japanese Patent Application Laid-Open Nos. 1-222641, 9-195343, 9
As shown in -170249, there is an example in which pipe joints for water supply and drainage are provided in the same unit, but the use is limited to a washing machine only or a kitchen only.

[0003] In recent years, there has been an increasing number of retrofitting water-supplying devices, such as washing machines, arbitrarily selected and installed by consumers, instead of water-supplying devices installed as building equipment. If the water is supplied more than the water flow capacity, there is a risk that the drainage section will be full and overflow. In order to prevent this, the designated contractor managing the water supply was responsible for setting the drainage capacity to be greater than the amount of water used for drainage, but this was not known to consumers.

[0004] In recent years, regulations have been deregulated and the locally managed designated construction shop system has been abolished, so that consumers can arbitrarily select a construction company. Therefore, there is a possibility that a mismatch may occur between the hot water supply / water supply / drainage pipe, which is one of the building structural members, and the water utilization equipment connected thereto. Furthermore, the expansion of products such as washing machines that consumers may connect and install themselves could be a big problem.

[0005]

The problem to be solved in the present invention is not only for the water supply equipment which is designed in advance by building equipment, but also for the equipment to be used in the future, which will be expanded in the future and which can be selected by the user as needed. Another advantage is that the pipes can be connected with confidence. Another object of the present invention is to provide a plumbing apparatus that can install a plumbing device in accordance with the capacity of the plumbing equipment even when the equipment is replaced, such as when upgrading or renovating.

[0006]

The present invention is installed on a wall or a floor,
In a piping device having at least a pipe joint unit having a pipe connection part for water supply and drainage, a drainage capacity display part for displaying a flow capacity of drainage is provided in the pipe joint unit, and there is a relationship between the water supply and the drainage. Is easily transmitted to the connection position.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In addition, a flow rate adjusting means is provided on the water supply side so that water is not supplied beyond the indicated drainage capacity.

In order to secure and maintain the indicated capacity, a flow control valve, a checkable water trap and the like are provided in the pipe joint unit. In addition, it was decided to use it for a drainage header piping system that also has a stable drainage capacity.
