[0003] [Patent Document 1] JP 2017-48566 A Summary of the Invention [Problem to be solved by the invention]
[0004] The functional unit devices are arranged closely together on the base plate, so that the fixing parts for fixing to the base plate are adjacent to other functional unit devices. Therefore, when installing the functional unit devices on the base plate, it is necessary to arrange and fix each device to the base plate, which causes a problem of poor workability. Since the functional unit devices are arranged side by side along the upper surface of the base plate, when a large number of devices are installed, the planar shape of the functional unit becomes large, and there is a risk that the toilet device becomes large.
[0005] The present disclosure aims to provide a toilet apparatus that can improve ease of installation when installing a functional unit on a toilet body, and can reduce the planar shape of the functional unit. [Means for solving the problem]
[0006] In order to achieve the above-mentioned objective, the toilet apparatus of the present disclosure comprises a toilet body, a first base plate fixed to the toilet body, and a first functional part fixed to the first base plate, the first functional part being located below the first base plate, and the first base plate being fixed from above.
[0007] In order to achieve the above object, the toilet apparatus according to the present disclosure comprises a toilet body having a toilet bowl, and a first functional part and a second functional part arranged vertically stacked on top of each other behind the toilet bowl.
