Abstract

PURPOSE:To prevent bathtub water from being polluted with contaminant discharged from a filter even when the filter is reused by carrying out the filtration process of bathtub water for a specified period before the washing process of filter, and washing the filter using the clean water supplied to the bathtub as washing water. CONSTITUTION:The filter 35 is so connected in a circulation water passage 26 that water is allowed to flow in both the normal and the reverse directions of the filter 35 through the circulation water passage 26, changing-over valves 28, 29 and a bypath 30. A discharged water passage 13 is connected to the circulation water passage 26 so that the wash water having washed the filter 35 is discharged to the outside of the system. By pushing a wash switch 39, a controller 36 controls in such a way that washing is automatically carried out after filtration has been carried out for a specified period. Namely, the filter is washed using the clean water supplied in the bathtub 25 as wash water so that the bathtub water is prevented from being polluted again in the reuse of the filter without the appearance of contaminant, such as hairs.
