  • Patent number: 6948194
    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 sensor 11 is amplified by an amp 31, and a frequency spectrum is determined by an FFT calculation portion 32. A flow rate is determined by conversion in a flow rate calculation portion 33 on the basis of the frequency spectrum. A controller 34 operates other devices on the basis of the flow rate calculated by the flow rate calculation portion 33 and the operational state of a cleaning instruction button 16. Cleaning water supply valve 36 is opened and closed in accordance with instructions from the controller 34.
