ABSTRACT:
An object of the present invention is to provide a toilet cleaning device which is capable of cleaning a toilet stool by supplying cleaning water in an appropriate quantity corresponding to the state of usage by a user, which is provided with a self-diagnosis function for diagnosing cleaning water stoppage or the like, and which has a simple constitution so that maintenance can be performed easily. The output of a Doppler sensor11is amplified by an amp31, and a frequency spectrum is determined by an FFT calculation portion32. A flow rate is determined by conversion in a flow rate calculation portion33on the basis of the frequency spectrum. A controller34operates other devices on the basis of the flow rate calculated by the flow rate calculation portion33and the operational state of a cleaning instruction button16. Cleaning water supply valve36is opened and closed in accordance with instructions from the controller34. Electrolyzed water is generated in an electrolyzed water generating portion38to prevent the formation of urinary calculus in a drainpipe, and this electrolyzed water is discharged from a water spout when an electrolyzed water supply valve39is opened.
