Abstract: According to the embodiment, a toilet device includes a detector and a controller. The detector is detecting whether or not flush water is at a position lower than a full level and higher than a seal level at a surface of a bowl of a flush toilet. The controller is determining a clog state of the flush toilet based on a detection result of the detector after a flush water supplier is closed. The flush water supplier is located in a flow channel discharging flush water into the bowl. The position of the detection region of the detector at the surface of the bowl is separated from flush water flowing in a vertical direction from a water discharge port of the flow channel toward a bottom portion of the bowl after the flush water supplier is closed.

Abstract: The toilet device includes a toilet 800 and a sanitary washing device 100 mounted on the toilet 800. The sanitary washing device 100 includes a nozzle 473, a casing 400, a toilet seat 200, a toilet lid 300, and an illuminator 700. When the user operates an operation part 500 built into the interior of the casing 400, the nozzle 473 is advanced into the bowl 801 of the toilet 800. The casing 400 includes a nozzle container 480 that can store the entire nozzle 473. The illuminator 700 irradiates sterilizing light which is light having a sterilizing action. The illuminator 700 irradiates the sterilizing light L directly on the front surface 473a of the nozzle 473 and/or the part 480c of the bottom surface part 480b positioned below the front surface 473a.
