<p>PURPOSE:To make it possible to detect failures easily by installing a state memory means having a man-volatile memory which starts detection data detected with a state detection means even when a sanitary device receives no power supply. CONSTITUTION:When a user sits on a closet seat and depresses a hip flushing pushbutton switch 13a, for example, a signal is outputted to an input processing circuit 10a of an electronic control device 100 from a sit-on seat sensor 15a and an operation pushbutton switch 13A. The signal is outputted from an output processing circuit 109 to a first on/off valve 37a so that the valve may be opened so as eject flushing water from a nozzle device. When a sit-on seat counter exceeds a specified time, a failure state determination flag of the sit-on seat sensor 15a is set so that such operations as flushing may be halted and the failure determination flag thus set is stored in a back-up RAM 107. When the sit-on seat time exceeds a setting sitting time, it is determined as a failure of the sitting sensor 15a due to this construction and used as data for detecting failuie when molding.</p> |
