Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cleaning port structure for a piping unit.

(Prior Art) A urinal-equipped piping unit including a frame body for accommodating a piping system such as a drain pipe and a front plate covering the front surface of the frame body, for example, a urinal attached to the front plate Plumbing units are known. In such a piping unit, conventionally, the cleaning port for the drainage pipe is provided inside the piping unit.

(Problems to be Solved by the Invention) However, according to the above-described conventional cleaning structure,
In order to clean the inside of the drainage pipe, it was first necessary to remove the urinal and the front plate from the frame. Therefore, there is a problem that the urinal and the front plate must be detachably attached to the frame.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning unit structure for a piping unit, which can clean a drain pipe without removing a device such as a urinal and a front plate.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a piping unit including a frame body for accommodating a piping system such as a drain pipe, and a front plate that covers the front surface of the frame body. , A screw adapter that is upstream of the drain pipe and communicates with the drain pipe and forms a cleaning port above the drain pipe is provided. The body was screwed onto the screw adapter.

(Operation) A screw adapter is provided on the upstream side of the drainage pipe, which communicates with the drainage pipe and forms a cleaning port above the drainage pipe. A mounting hole is provided on the front plate facing the screw adapter. Since the covering lid is screwed to the screw adapter, the inside of the drain pipe can be easily cleaned by removing the lid and inserting a cleaning tool such as a brush into the screw adapter forming the cleaning port.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

 FIG. 1 is a perspective view of a piping unit.

In the figure, Wa and Wb are side walls defining the indoor space of the toilet, and F is the same floor. The piping unit 1 is arranged on the floor F along the side wall Wb.

The piping unit 1 has a rectangular frame shape, and includes a frame body 2 that houses the piping system 3 therein, a front plate 7 that covers the front surface of the frame body 2, and a counter 8 that covers the upper surface of the frame body 2. It becomes. The piping system 3 includes a water supply pipe 4, a ventilation pipe 5 and a drain pipe 6.

The front plate 7 has two urinals 10, 10 in this embodiment.
Are installed side by side, and a partition plate 12 is arranged between these urinals 10, 10. Wash water flows out of the water supply pipe 4 into the urinals 10 and 10 through a flush valve 11.
Then, the sewage in the urinals 10, 10 is discharged through the drain pipe 6. The ventilation pipe 5 communicating with the drain pipe 6 prevents a negative pressure from being generated in the drain pipe 6. The cleaning port 9 of the drainage pipe 6 of the piping unit 1 configured as described above has the front plate 7
Is installed in.

 FIG. 2 is a sectional view taken along the line II-II in FIG.

The front plate 7 is composed of a surface member 7a and a reinforcing member 7b, and a mounting hole 7c, which is an opening communicating with the inside and outside of the piping unit 1, is formed in the front plate 7 on the side of the urinal 10. This mounting hole
A screw adapter 92 forming a cleaning port faces the 7c, and a lid 91 made of bronze or the like that is detachable from the front of the front plate 7 is attached to the screw adapter 92. The screw adapter 92
A connecting short pipe 93 is connected to the rear part of the rear portion, and the connecting short pipe 93 extends rearward from the screw adapter 92. A 90 ° elbow pipe 94 is connected to the rear part of the connecting short pipe 93.
94 bends downward. A standing pipe 61 standing upright from the drainage pipe 6 is connected to the lower end of the 90 ° elbow pipe 94.

According to the above embodiments, since the cleaning port 9 is provided in the front plate 7, the inside of the drainage pipe 6 can be cleaned only by removing the lid 91, and the equipment such as the urinal 10 and the front plate. It is not necessary to remove 7 from the frame 2. Therefore, it is not necessary to make the device such as the urinal 10 and the front plate 7 detachable to the frame 2, and the mounting structure is simplified and the urinal is
Devices such as 10 and the front plate 7 can be firmly fixed to the frame body 2.

In the above, the case of the urinal-equipped piping unit has been described, but it is a piping unit provided with a frame body for accommodating a piping system such as a drainage pipe and a front plate that covers the front surface of the frame body. It can be similarly applied to other piping units.

(Effects of the Invention) As is apparent from the above description, according to the present invention, in a piping unit including a frame body for accommodating a piping system such as a drain pipe, and a front plate covering the front surface of the frame body, A screw adapter that connects to the drain pipe and communicates with the drain pipe and forms a cleaning port above the drain pipe is provided, and a mounting hole is provided in a front plate facing the screw adapter, and a lid body that covers the mounting hole. Since the screw adapter is screwed onto the screw adapter, the inside of the drain pipe can be easily cleaned by removing the lid and inserting a cleaning tool such as a brush into the screw adapter forming the cleaning port.
