BATH WATER CIRCULATING AND PURIFYING APPARATUS

摘要

PURPOSE:To simplify constitution and to simplify the replacement or cleaning of a filter apparatus by constituting the filter apparatus of a plurality of filters and the flow passages connecting the plurality of the filters. CONSTITUTION:The bath water supplied to a filter apparatus 23 flows in a filter part 23b to be filtered through the filter 23 such as porous ceramic in the filter part 23b and flows in a filter part 23d to be activated and filtered by the chemical stone 23e in the filter part 23d to flow in a filter part 23f. The bath water is activated and filtered by the chemical stone 23g in the filter part 23f to flow in a filter part 23h, and is filtered through the activated carbon 23i in the filter part 23h to flow in a filter part 23j and filtered through the activated carbon 23k in the filter part 23j. Thereafter, the filtered water flows in a connection pipe 31 to be heated by the heater 24 in the connection pipe 31 to be returned to a bathtub 1 from an emitting port 26a through an emitting pipe 26.
