PROBLEM TO BE SOLVED: To provide a cup-shaped trap equipped with a replenishing liquid tank, which is automatically supplied with a replenishing liquid before water in the water-sealed deodorized cup-shaped trap is decreased to disable water-sealing/deodorizing and moth-proofing functions, the cup-shaped trap being for use in a water-sealed deodorized cup-shaped trap-type draining mechanism set under a floor surface of a toilet, a wash room, etc., in order to improve the environment of a contaminated area which particularly tends to be environmentally filthy caused by a back-flow of odors and entry of insects. SOLUTION: There is provided a fundamental system of the water-sealed deodorized cup-shaped trap, which is set under the floor surface of the toilet, the wash room, etc. According to the system, an upper portion of a deodorization cup 2 of the trap is formed into a liquid tank structure which has a liquid supply channel 5 for supplying the liquid from the liquid tank 4 to a lower portion of a trap body 6. Therefore when water for water sealing is decreased, the liquid is automatically replenished from the liquid supply channel 5 of the liquid tank 4 to the trap body 6. COPYRIGHT: (C)2004,JPO
