- FIG. 1 of Patent Document 1 discloses another conventional urinal drain trap.
- This urinal drain trap is also formed in the form of a cartridge and includes a lid, a main body, and a partition.
- the urinal drain trap is fitted into the urinal by being fitted into an opening provided at the lower end of the bowl surface of the urinal.
- the lid portion has a circular shape in plan view.
- the main body has a cylindrical side wall, a bottom formed continuously at the lower end of the side wall, and an outlet from which stored urine overflows.
- An inflow port through which urine that has flowed down along the bowl surface flows is formed between the peripheral edge of the lid and the side wall of the main body.
- the partition wall portion extends downward from the lower surface on the inner side of the outer peripheral edge portion of the lid portion, and is formed with a space between the bottom portion.
- the partition wall has a cylindrical shape with an open lower end.
- the inside of the main body is partitioned by a partition wall into a first region formed outside the partition wall and a second region formed inside.
- the first region and the second region are communicated with each other by a third region formed below the lower end of the partition wall and above the bottom.

- the outflow port rises from the bottom of the main body in the second region and is formed at the upper end of a cylindrical outflow pipe disposed concentrically with the partition wall.
- the sealing layer can prevent the urine odor stored in the main body from escaping from the inlet to the outside. Moreover, the backflow of the odor from the drainage channel connected to the downstream side can be blocked by urine stored in the main body. For this reason, the urinal having the urinal drain trap can be used satisfactorily without causing odor to escape from the inflow port to the toilet room without using any washing water.
- the seal liquid that has been transported to the second region cannot return to the first region and flows out from the outlet. For this reason, with a long-term use, a sealing liquid flows out from an outflow port gradually, a sealing liquid reduces and a sealing layer becomes thin. If the seal layer is thin, the stored urine odor may be emitted from the inflow port.
- the outflow pipe is disposed concentrically with the partition wall, and the ascending flow path of urine in the second region is formed between the outer surface of the outflow pipe and the partition wall. It is formed with a certain distance from the inner surface. Since urine is retained in this portion, gel-like urinary stones are likely to adhere. If the distance between the outer surface of the outflow pipe and the inner surface of the partition wall is narrow, the ascending flow path will be clogged early by the accumulation of gel-like urine that adheres to the outer surface of the outflow pipe and the inner surface of the partition wall. There is a risk that.

For this reason, it is possible to reduce the amount of the sealing liquid that rides on the flow of urine and crosses the upper end of the folded portion from the convection area, so that the outflow of the sealing liquid can be suppressed.
- the gel-like urolith adheres to the inner surface of the convection area, the gel-like urolith does not easily deposit in the convection area. For this reason, it is possible to prevent the sealing liquid from flowing out because gel-like urine stones accumulate at a specific location at an early stage and no convection occurs at that location. Therefore, it is difficult for the seal layer to be thin, and odor emission can be prevented.
