Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a piping structure characterized by the position of a cleaning port for cleaning clogging of a drain pipe of a urinal.

(Prior Art) Conventionally, as a drainage pipe of a urinal, a drainage horizontal pipe having a drainage gradient is horizontally provided below the urinal, and the drainage horizontal pipe and the drainage outlet of the urinal are connected by a drainage vertical pipe. There is.

Such a horizontal drain pipe has a slope for smooth drainage, but for example, when a large number of urinals are installed in a line, the pipe distance becomes long and the pipe becomes easily clogged. A cleaning port may be provided at one end on the upstream side of the slope. When the inside of the pipe was clogged, a cleaning tool for the inside of the pipe was inserted through this cleaning port for cleaning.

(Problems to be solved by the invention) However, in the conventional case, since the position of the cleaning port is provided at a low position around the axis of the drainage horizontal pipe without considering the height position of the urinal, it is necessary to perform cleaning at the time of cleaning. There was a problem that when the lid of the cleaning port was opened, the accumulated sewage flows backward and flows out.

(Means for Solving the Problem) In order to solve the above problem, the present invention provides one end of a horizontal drain pipe which is horizontally arranged below the urinal and which communicates with a drain outlet of the urinal by a vertical drain pipe. In the piping structure of the urinal drainage pipe having a cleaning opening for cleaning the inside of the piping, the cleaning opening is provided at a position higher than the overflow surface of the urinal.

(Function) When the drain pipe is clogged and dirty water is collected, the water level does not become higher than the overflow surface of the urinal, so that the cleaning port is made higher than the overflow surface to prevent backflow.

(Example) An example of the piping structure of the urinal drainage pipe of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a front view showing the piping structure of a urinal drainage pipe, and FIG. 2 is a side view seen from the direction A in FIG.

The piping structure of the urinal drainage pipe of the present invention is constituted by connecting a plurality of simultaneous urinals 1 as shown in FIG.

That is, a drainage port 1a as shown in FIG. 2 is provided on the rear surface of the urinal 1, and the drainage port 1a is connected via a connecting pipe 2 to a standing pipe extending vertically in the back of the toilet bowl. As shown in FIG. 1, this standing pipe is constituted by connecting a ventilation standing pipe 3 communicating with an upper ventilation lateral pipe 4 and a drainage standing pipe 5 extending downward in a straight line. Is provided with a deodorizing fan (not shown) and is configured to deodorize the urinal.

The drainage vertical pipe 5 is connected to a drainage horizontal pipe 6 which is installed laterally below, and this drainage horizontal pipe 6 is attached with a drainage gradient of 1/50 in the case of the present embodiment, and the slope downstream side is external. It communicates with the drainage system. A bend connecting pipe 7 is connected to the end of the drainage horizontal pipe 6 on the other end side so that the pipe line is directed upward, and an upright pipe 8 is connected to the upper end of the bend connecting pipe 7 so that the upper opening serves as a cleaning port 9. While being formed, the lid 10 is configured to be attachable.

Further, the height of the upper surface of the cleaning opening 9 is set to a position higher than the overflow surface a of the urinal 1 as shown in FIG.

The clogging and the like in the pipe configured as described above are removed by, for example, a pipe cleaning tool such as a relatively rigid flexible wire provided with a brush-like cleaning tool.

(Effect of the Invention) As described above, the present invention makes it possible to eliminate the conventional inconvenience that sewage flows backward from the cleaning port during cleaning because the cleaning port of the pipe is higher than the overflow surface of the urinal. .

Claims (1)

[Scope of utility model registration request] 1. A urinal arranged horizontally below a urinal, and having a cleaning port for cleaning the inside of the urinal at one end of a horizontal drain pipe communicating with the drain of the urinal by a drain pipe.
