A sanitary device includes a radio wave sensor, a control section. The radio wave sensor is configured to obtain information on a sensing target by a reflection wave of an emitted radio wave. The control section is configured to control operation of an instrument based on a sensing signal including a first signal and a second signal outputted from the radio wave sensor. Difference between a phase of the second signal and a phase of the first signal is not less than 60&#xb0; and not more than 120&#xb0;. The control section is configured to determine presence or absence of the sensing target based on sum of square of difference between a value of the first signal and a first reference value and square of difference between a value of the second signal and a second reference value.

Sanitary device

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 sensoris amplified by an amp, and a frequency spectrum is determined by an FFT calculation portion. A flow rate is determined by conversion in a flow rate calculation portionon the basis of the frequency spectrum. A controlleroperates other devices on the basis of the flow rate calculated by the flow rate calculation portionand the operational state of a cleaning instruction button. Cleaning water supply valveis opened and closed in accordance with instructions from the controller. Electrolyzed water is generated in an electrolyzed water generating portionto prevent the formation of urinary calculus in a drainpipe, and this electrolyzed water is discharged from a water spout when an electrolyzed water supply valveis opened.
