Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a flush urinal that can prevent flushing water from overflowing from the urinal lip when the perforated plate at the bottom of the urinal becomes clogged.

[Conventional technology]

Conventionally, some flush-type urinals have a structure in which a water-seal trap section with a flush water discharge function is provided at the bottom of the urinal body as a means for discharging flush water, and a perforated plate is arranged at the opening of the trap section. .

[Problem that the invention attempts to solve]

However, with conventional configurations, when the perforated plate becomes clogged with foreign matter thrown into the urinal or substances generated by changing urine after excretion, the flushing water collects at the bottom of the urinal body and flows out from the lip. There is a risk of overflowing outside the urinal.

In particular, public urinals are used by an unspecified number of users, so it is difficult to avoid clogging of the perforated plates due to foreign objects being thrown into them.Furthermore, when flushing water is flushed into multiple urinals at the same time using a hand tank, even if the perforated plates are Even if the urinal is clogged, the flushing water is flushed out, so every time the flushing water is flushed, the flushing water overflows from the urinal, which is not only unsanitary, but also causes the urine mixed in the flushing water to emit a bad odor, The scaffolding in front of the toilet becomes dirty, causing significant discomfort to the user.

In view of the above-mentioned problems with the conventional technology, the present invention has been developed to allow cleaning water accumulated at the bottom of the urinal to overflow below the lower lip position and be discharged even when the perforated plate at the bottom of the urinal becomes clogged. To provide a flush-type urinal that can prevent water from overflowing from its lip.

[Means for solving problems]

The gist of this invention, which achieved the above objectives, is as follows:
In a flush urinal consisting of a urinal body and a trap, an overflow opening is provided at a position between the perforated plate placed at the upper end of the trap which is open above the bottom on the inner wall of the urinal and the lower end of the lip, and the opening and trap are connected to the overflow water. They are characterized by being connected through a passageway.

[Effect]

The flush urinal according to the present invention has the above-mentioned configuration, and when the perforated plate becomes clogged, flushing water accumulates at the bottom of the urinal and the water level rises, reaching the overflow opening provided at a suitable location on the inner wall of the urinal body. Then, the wash water flows from the overflow opening into the trap through the overflow water passage and is discharged, so the water level of the wash water does not exceed the overflow opening position, preventing the wash water from overflowing from the lip. It can be prevented.

〔Example〕

The details of the present invention will be explained based on further illustrated embodiments. FIG. 1 shows a typical embodiment of a flush urinal according to the present invention.

A lip 7 is formed on the front surface of the urinal main body, indicated as 1 in the figure, as an opening surface for urination, and a urination surface 8 is formed on the inner wall at the rear.

A washing water spouting valve is provided at a suitable upper part of the urination surface 8 with its tip facing forward of the water spouting surface 8, and the washing water spouting valve 4 is connected to a high tank or a flush tank (not shown) via a water supply pipe 5. It is connected to the tsushi valve.

A cylindrical trap 9 with a bottom is located at the bottom of the urinal body 1.
A perforated plate 10 is provided at the upper end of the trap 9, which is open upward, and is made of a plate-like member with a large number of openings. A drain pipe 12 is provided at the other end of the trap 9, passing through the side wall of the trap 9 and communicating with a drain pipe 11.

Further, an overflow opening 14 is bored in the inner wall 13 below the lower end of the lip portion 7, and the overflow opening 14 is connected to the trap 9 through an overflow water passage 16 provided in the gap between the inner wall 13 and the outer wall 15. are doing.

The overflow water flow passage 16 shown in FIG. 1 is formed using the space between the bowl-shaped wall 18 for forming a flow passage provided externally on the inner wall 13 and the inner wall 13, but as shown in FIG. Overflow opening 1
4 and the opening 17 in the side wall of the trap may be connected to each other by a tubular member 19.

Further, the overflow opening 14 may be provided at any location other than the location shown in the figure as long as it is located between the perforated plate 10 and the lower end of the lip portion 7 on the inner wall of the main body 1.

In the flush urinal of the present invention constructed as described above, if the opening provided in the perforated plate 10 is blocked and clogged, the flush water jetted from the jet nozzle 4 will accumulate at the bottom of the main body 1, and the water level will rise. However, when the water level reaches the overflow opening 14 position, the cleaning water flows from the overflow opening 14 through the overflow water flow passage 16 into the trap 9 and is discharged from the drain pipe 12, so that the cleaning water level reaches the overflow opening 14. Washing water can be prevented from overflowing from the lip portion 7 without exceeding the position. In addition, as shown in the figure, an overflow opening 14 is provided.
When it is provided on the inner wall 13 below the lower end of the lip portion 7, the overflow opening 14 and the inside of the overflow water passage 16 are not visible to the user, resulting in a good appearance.

[Effect of idea]

As described above, the flush urinal according to the present invention is
An overflow opening is provided at a position between the perforated plate placed at the upper end of the trap which is open above the bottom of the inner wall of the urinal and the lower end of the lip, and the opening and the trap are connected in communication through an overflow water flow passage.
If the perforated plate is clogged, even if flushing water accumulates at the bottom of the urinal and its water level rises, when the flushing water level reaches the overflow opening position, the flushing water will be trapped from the overflow opening through the overflow water passage. The level of the flushing water does not exceed the overflow opening position, preventing flushing water from overflowing the lip, and keeping the urinal and the environment around it clean. It can be done.
