[Technical field to which the invention belongs]
The present invention relates to a bath water sterilizer having a cleaning function in a bath water circulator capable of satisfactorily purifying a protective tube provided in an ultraviolet sterilizer lamp used in the bath water circulator.
[0002]
[Prior art]
Various devices have been developed in which bath water in a bathtub is circulated by a circulation pump, purified, sterilized, and sent again to the bathtub. Purification by these devices is performed in a filtration tank made of activated carbon, barley stone, etc., and sterilization is performed by passing the bath water through a sterilization tank with a built-in ultraviolet lamp, and generating ozone using an ozone generator. The ozone was sterilized by mixing the ozone into the bath water and sterilizing. The conventional bath water circulation apparatus not only removes the dirt of the bath water as described above, but also provides a bath water apparatus that can perform bathing comfortably for 24 hours by simultaneously performing sterilization and heat insulation.

[Problems to be solved by the invention]
When sterilizing using an ultraviolet germicidal lamp (simply referred to as a germicidal lamp), it is desirable to provide a protective tube made of glass or quartz material that transmits ultraviolet light in order to prevent electrical damage and damage to the germicidal lamp. It is. However, in the water treatment such as bath water, the protective tube is soiled and the transmittance of ultraviolet rays gradually decreases, so that cleaning has to be performed regularly once every six months. The germicidal lamp has a lifetime, and the replacement frequency is once every few years for the cold cathode type and once every two to one year for the hot cathode type.
[0004]
As a conventional cleaning method, the protective tube has to be removed from the sterilization unit and manually removed with a cloth soaked in detergent. This series of work consists of (1) temporarily stopping the operation of the bath water circulator, (2) removing the cover of the bath water circulator, (3) removing the screw on the lid where the sterilization unit is housed, and (4) Remove the protective tube and sterilizing lamp from the sterilizing unit, and (5) separate the protective tube and sterilizing lamp. (6) Remove the dirt adhering to the protective tube with a cloth etc. with gloves. After that, (7) the sterilization lamp is set in the protection tube, (8) the protection tube and the sterilization lamp are set in the sterilization unit, (9) the sterilization unit is set in the apparatus, and finally the lid of the sterilization unit is closed. There was a lot of work, and it was extremely troublesome even once every six months, and sometimes a lamp placed near the work was broken.
