The inside of the electrolytic sterilizer 7 is formed as an electrolytic cell having a structure in which an anode and a cathode are arranged. When electricity is applied to the electrolytic sterilizer 7, a current flows through the anode plate and the cathode plate, the bath water is electrolyzed, and chlorine ions are generated,
The bacteria in the bath water are sterilized, and the off-flavor of the bath water is removed by the deodorizing action.

FIG. 4 is a control block diagram of the apparatus according to the present invention. FIG. 5 is a functional block diagram showing the first sterilizer as an ozoneizer and FIG. 6 as an ultraviolet sterilizer. The embodiment of claim 1 of the present invention will be described with reference to the flowchart of FIG.

In step S1, the bath water circulating device A first turns on the power by the power switch 10 of the bath water circulating device main body A to start the operation. In S2, the circulation pump control unit 3a instructs the circulation pump 3 to be driven when the power is turned on, whereby the bath water of the bath water device is circulated.

In S3, a flow rate sensor 4 is installed to confirm whether the purification filter 2b or the pipe for circulating the bath water is clogged with dust or dirt, and the flow rate is detected. Whether or not the flow rate detected by the flow rate sensor 4 is proper is confirmed at T1, and if normal (YES),
If the flow rate is not appropriate due to clogging (NO), go to S4.
Go to S12.

In S12, it is confirmed that an abnormality has occurred, and the power supply to each electric control unit is stopped. There are cases where the flow rate is abnormal when the flow rate is less than the proper value and when the flow rate is abnormal. The cause of the decrease is the clogging of the filter and the like, which causes an overload on the circulation pump, which causes failure due to abnormal heating of the pump.

The cause of the increase in the flow rate is that water is leaking due to a hole in the pipeline or the like. As a result, the bath water is splashed inside the device, which may cause a failure or an electric leakage.

In step S13, a user is warned that an error has occurred in the flow rate by displaying on a display device 9 composed of a liquid crystal panel installed in the bath water circulation device or by a warning buzzer or the like.

In S6, a constant current is supplied to the electrolytic sterilization device 7, and the bath water is electrolyzed by the anode and cathode electrode plates of the electrolytic sterilization device 7. In S7, the current passing through the electrode plate is detected by the current sensor 8, and it is determined in T3 whether the current value is proper.

If more than a predetermined current flows due to an electric leakage or the like, the process goes to S12 to confirm that an abnormality has occurred as in the bath water flow rate abnormality and the heating abnormality, and the energization is stopped. Then S
At 13, the warning is displayed on the display device 9 in the same manner as the abnormality of the flow rate and the abnormality of the heater.

As the amount of current, a current within a range that does not have any effect on the human body is used, but if an abnormality such as a leakage occurs in the device, the current supply is stopped before the warning is displayed for safety. When an abnormality such as a leakage is confirmed at T6 and the abnormality is released, the program returns to S2.

When it is confirmed in S8 that the current value is normal, electrolytic sterilization is started. In S9, electricity is supplied to the lamp for UV sterilization for normal sterilization. S10
Then, the current value is detected by the current sensor to see if there is any abnormality in the energization of the ultraviolet lamp.
