The drain pipe of the drainage pipe 4 is connected to the lower end of the vertical connection pipe 2 fastened to the lower part of the washstand 1 and to the wall WL. The P trap pipe 3 is fastened by the octagonal slip nuts 5 and 6 to form the P trap drainage device 10. The foreign matter (such as the hair 7) (Retention number: W) in the curved portion of the pipe 3.

Such a washstand drainage device discharges directly through the vertical connection pipe (2) -P trap pipe (3) - bending drain pipe (4) in a state in which no foreign matter (7) mixed in water passing through the washstand (1) The foreign matter 7 such as hair, soap pieces, and debris may be retained in the P trap pipe 3 to block the fluid flow of the drain water or the P trap pipe 3, There is a problem that the sewage drainage line is clogged up in the drainage line connected to the lower side rather than being accumulated in the drainage line, and the smell due to the corruption due to accumulation of foreign matter is backwashed to the sink.

In order to solve such a problem, the user can periodically remove the octagonal slip nuts 5 and 6 and remove the P-trap tube 3 to clean and remove the foreign matter, There were disadvantages such as troublesome and difficult, hygiene problems due to the neglect of cleaning due to the inability to check foreign matters from the outside.

In order to solve the above-described problems, foreign matter filtering devices for a washstand as shown in Patent Documents 1 to 3 have been disclosed.

However, in the above-described seawater technology, it is difficult to separate the filter bag or the filtering net. In addition, since the filtering bag is merely a foreign matter filtering function and the fresh water storage function of the stored water is not provided, I could not block it.

In particular, water is stagnant in the bottomed passageway without the function of preventing backflow, and only the filtering function is provided, and when the large amount of water is drained from the vertical pipe, the trapping seal can not be prevented from flowing backward to the inside of the room.
