Next, the operation will be described with reference to a flowchart (see FIG. 2). First, after cleaning the outer tube 3 (once every 6 months) and replacing the UV lamp 1 (once every several years), as shown in FIG. 5, the UV lamp 1, the cover 9, and the connector 8b are not attached. The magnetic proximity switches 10a and 10b remain open. Therefore, as shown in FIG. 4, the UV lamp 1 and the lamp base 2 with the outer tube 3 are inserted into the housing 5. That is, the UV lamp 1 is attached (see S1). At this time, the magnetic proximity switch 10 b senses the magnetic (see S2), attachment of the UV lamp 1 it is determined whether normal (see S3). When the installation of the UV lamp 1 is not normal, the UV lamp 1 is prohibited from being turned on (see S4), and the alarm content is displayed on the display device 25 (see S5). Is, for example, “Please attach UV lamp again”.
[0016]
If the UV lamp 1 is normally attached, the cover 9 is attached to the main body 15 as shown in FIG. 3 (see S6). At this time, (see S7) magnetic proximity switch 10 a senses the magnetic, attachment of the cover 9 to determine whether the normal (see S8). When the attachment of the cover 9 is not normal, the lighting of the UV lamp 1 is prohibited (see S9), and the alarm content is displayed on the display device 25 (see S10). For example, “Please attach the cover again”. When the cover 9 is normally attached, that is, when there is a detection signal from the sensors A and B, the lighting control means 21 causes the current of the inverter circuit 6 to flow to start lighting the UV lamp 1. (See S11). And the operation | movement of the ultraviolet sterilizer for water is started (refer S12). Further, when there is a detection signal from the sensors A and B, the operation control means 26 starts the circulation pump 27 (see S13), and the bath water purification and circulation device is operated for 24 hours.
