WASTEWATER TRAP

Provided is a highly-durable wastewater trap that is capable of preventing condensation while maintaining an aesthetically-pleasing appearance. The present invention comprises: a closed-bottom tubularbody 5 in which a receiving pipe 2 for receiving a liquid and a discharge pipe 3 for discharging the liquid are formed in side walls 51; a divider 1 that divides an internal space 4 of the body 5 into a reservoir space 7 that communicates with the receiving pipe 2 and stores the liquid, and a discharge space 8 that communicates with the discharge pipe 3 and discharges the liquid; and a sealed case 9 that encompasses, in a sealed state, at least a portion of an outer surface of the body 5 where the reservoir space 7 is formed. A gap 91 is formed between the sealed case 9 and the body 5. 提供一种易于维护、能够防止结露且耐久性高的排水疏水器。排水疏水器包括：底筒状的本体部分(5)，本体部分的侧壁(51)上形成有用于接收液体的接收管部分(2)和用于排出液体的排出管部分(3)；可连接/可拆卸的分隔体(1)，用于将本体部分(5)的内部空间(4)分隔成储存空间(7)和排出空间(8)；盖部分(6)，用于封堵本体部分(5)的内部空间(4)；密封壳体(9)，在密封状态下至少包围本体部分(5)形成有储存空间(7)的部分的外表面。密封壳体(9)与本体部分(5)
