<p>A stool flushing device which supplies flushing water in a proper amount according to a user’s using condition to flush a stool, is provided with a self-diagnosing function for such as cut-off flushing water, and is simple in construction and easy to maintain. An output from a Doppler sensor (11) is amplified at an amplifier (31) and has a frequency spectrum determined at an FFT calculating unit (32). It is converted into a flow rate at a flow rate calculating unit (33) based on the frequency spectrum. A controller (34) operates other devices based on a flow rate calculated at the flow rate calculating unit (33) and the operation status of a flushing instruction button (16). A flushing water supply valve (36) is operated by an instruction from the controller (34). An electrolytic water generating unit (38) generates an electrolytic water for preventing the formation of uroliths inside a drain pipe, and an electrolytic water is fed out from a discharge port when an electrolytic water supply valve (39) is opened.</p> |
