Japanese Patent No. 6374626

By the way, when renovating the plumbing, there are cases where the position of the existing faucet is changed or a new faucet is installed in a new position. It was necessary to change the buried pipe, which took time and effort. In other words, the conventional faucet lacks flexibility because the position of the pipe on the wall connecting the faucet and the pipe is limited. As a result of intensive research, the applicant of the present invention invented a wall decoration box disclosed in Patent Document 1, which was patented.

However, the space for piping formed by installing the wall decoration box of Patent Document 1 is limited, and it was difficult to accommodate the hot and cold water mixing valve and to arrange hot and cold water pipes inside it.

The present invention has been made in consideration of the above-mentioned matters. Another object of the present invention is to provide a connecting structure of a faucet which is not affected at all by the exterior of a box for wall surface decoration and which allows piping within a limited space for piping.

In order to solve the above problems, the first invention has a rectangular parallelepiped or cubic framework, has cutouts extending from the rear surface, which is a wall mounting portion, to both longitudinal end surfaces, and is open vertically. a frame having a space for piping inside; a decorative panel covering at least the front surface of the frame; a faucet body mounted with an operation part projecting from the frame; Provided is a connection structure for a faucet, characterized by comprising a connected flexible water supply pipe and a discharge pipe connecting a discharge port of a faucet main body to the discharge port.

Since the front face of the frame can be covered with a decorative panel so as to form a space for piping in front of the wall surface, connection of pipes can be performed in the space for piping that is blinded. In addition, since the shape of the frame is rectangular parallelepiped or cubic, it is possible to secure as large a space for piping as possible enclosed by the decorative panel and the frame by securing a limited occupied volume. Note that the rectangular parallelepiped shape in the present invention includes not only an exact rectangular parallelepiped shape but also a substantially rectangular parallelepiped shape. Similarly, cubic shapes include exact cubic shapes and nearly cubic shapes.

Flexible water supply pipes are piped from either the left or right side of the faucet body in the piping space with a limited volume, even if the piping is buried in the wall surface. Even if it is, it can be connected flexibly. Since the water discharge pipe is connected to the discharge port fixed to the lower part of the frame, the amount of water can be adjusted by the faucet main body and the water can be discharged from the discharge port.

The frame may form a storage shelf on its top. Also, lighting fixtures may be accommodated within the frame. In this case, it is preferable that the decorative panel has light transmittance in order to sufficiently exhibit the lighting effect of the lighting equipment.

When the water supply ports are connected to the water supply pipes through elbow pipes that are rotatably connected to each other, the elbow pipes that are rotatably connected to the water supply ports communicate with the water supply ports. Since the pipes to be connected can be bent by approximately 90° and can be installed in any direction, the routing of the pipe flow path can be easily changed in a limited space for pipes.

The connecting portion between the water supply port and the elbow pipe includes a female relay pipe having a tubular inner diameter enlarged portion with a flange formed at the tip, and a female relay pipe inserted into the inner diameter enlarged portion to watertightly connect the communication flow path and an intermediate portion. A pipe joint comprising a male relay pipe formed by forming a flange on the outer periphery of the male relay pipe and a clip that maintains the abutting state of both flanges in the connected state of the male relay pipe and the female relay pipe. The configuration allows for the most efficient use of narrow piping space.

The discharge port is formed on the side surface of the faucet main body, and when the discharge pipe includes a plurality of elbow pipes and curved pipes rotatably connected to the discharge port, the elbow pipes can be used within a short distance. The direction of the water discharge pipe can be changed, and the water flow can be adjusted by the curved pipe and supplied to the water discharge port. In addition, the elbow pipe and the curved pipe are robust and can prevent problems such as water leakage from occurring.

The spout is attached to the lower part of the frame, and in the case where the spout is provided with a laterally widening spout opening in the lower part of the frame and a constricted part communicating with the spout opening, the water supplied to the spout is After the water flow is once throttled by the restrictor, it flows into the laterally widening water discharge opening, so that the water can be discharged forward while being laterally spread in the lower part of the frame.

As described above, according to the present invention, when refurbishing a plumbing area, the decoration panel can be used even in an environment where various pipes are installed without being affected by the configuration of the original faucet. It is possible to provide a faucet connection structure that is not only visually appealing, but also allows easy connection work with free piping in the piping space.
