The metal container 12 is provided with an inspection window 25 for checking whether the ultraviolet lamp 4 is turned on, and if the protective container 13 is soiled with scale, etc., the cleaning guideline can be known from the light intensity.

The material of the arc tube 19 of the ultraviolet wrap 4 is glass with good transmittance, such as quartz glass or silica glass.

The material of the protective container 13 is quartz or fluororesin (for example, perfluoro and tetrafluoroethylene copolymer plastics, talolotrifluoroethylene polymer glasstics, tetrafluoroethylene and 67) propylene copolymer plastics. ).

The metal container 12, which has an inner surface with a high ultraviolet reflectance, is made of stainless steel, an inner chrome-plated metal plate, an inner silver-plated metal plate, and glass (for example, quartz glass) having an aluminum vapor-deposited film on the outer surface.

Note that a configuration in which the protective container 13 and the inspection window 25 are not provided is also possible.

The third embodiment shows a configuration in which the jet device is arranged in the bath circulation flow path.
As shown in the figure.

The jet device 6 is arranged at the return path outlet section 7 of the bath circulation flow path 3. Its structure consists of a nozzle 26, a mixing chamber 27, and an air inflow pipe 28. Its operation is to blow a jet obtained by injecting from the nozzle 26 into the mixing chamber 27, and to generate a vacuum around the mixing chamber 27, air is aired from the air inlet 28. is sucked in and discharged into the bathtub 2 from the discharge port 29 along with a jet. On the other hand, the outlet 9 of the filter unit 8 is arranged around the mixing chamber 27, and the water from which scale has been removed by the vacuum generated by the jet described above is sucked in, and the water is sent in any direction along with the jet. It protrudes into the bathtub 2 from a discharge port 29 that can be changed into a water outlet 29.A filter 11 such as a wire mesh is disposed in the middle of the flow path of the filter unit 8, and scale is removed by passing the bathwater.

Another embodiment of the jet device is shown in FIG. Bath circulation flow path 3
