[Problems to be solved by the device]

 However, when the washing water tank is wrapped in the casing, the hand-washing pot can be installed only at the upper end of the casing. For this reason, the casing is a separate type with at least its upper end part as a hand-washing pot, and water or splash water in the hand-washing pot may get into the casing from the joint between the casing side and the hand-washing pot. In addition, since a pipe line and a joint are provided from the ball tap to the water spout in the washbasin, if water leaks from these pipes, the inside of the casing will also get wet and the humidity will increase.

Thus, by covering the wash water tank with the casing, it is not only preferable in terms of appearance but also capable of protecting the equipment. However, in the case of having a hand washing function, the infiltration of water into the casing is possible. Occurs as a new problem. In particular, when an electric device such as a sanitary washing device is housed in a casing together with a wash water tank, it may result in trouble such as electric leakage and deterioration of parts due to high humidity.

The problem to be solved in the present invention is to prevent water from entering the casing, which occurs when a casing is provided at the upper end of the casing, and to protect the stored equipment.
