Is performed according to the instruction of the control unit 6.
７は、圧力計よりなる水位センサであって、その出力
信号は前記の制御部に入力される。Reference numeral 7 denotes a water level sensor composed of a pressure gauge, and its output signal is input to the control unit.
前記の循環ポンプ２を運転して浴槽水を浄化フイルタ
３に循環させると、該浴槽水内の微小異物が除去され
る。When the circulating pump 2 is operated to circulate bathtub water through the purification filter 3, minute foreign substances in the bathtub water are removed.
第４図は、前記の往管４と浴槽１との接続部に泡風呂
ノズル８を設けた従来例である。この従来例においては
循環ポンプ２を作動させて泡風呂ノズル８から水−空気
混合流を噴出させると、浴槽水が浄化フイルタ３を流通
して微少異物が除去される。FIG. 4 shows a conventional example in which a bubble bath nozzle 8 is provided at a connection portion between the forward pipe 4 and the bathtub 1.

浴槽水を浄化フイルタに流通させて微小異物を除去し
ても、該浴槽水が殺菌される訳ではないので浴槽水内で
雑菌が繁殖することを完全には防止できない。Even if the bathtub water is circulated through a purification filter to remove minute foreign substances, the bathtub water is not sterilized, so that it is not possible to completely prevent the growth of various bacteria in the bathtub water.
特に、浄化フイルタ内には雑菌の栄養分となる有機質
成分が堆積されるので、この浄化フイルタ内に雑菌が繁
殖しやすい。In particular, since organic components serving as nutrients of various bacteria are deposited in the purification filter, various bacteria can easily propagate in the purification filter.
浄化フイルタ内で雑菌が繁殖すると、該浄化フイルタ
の耐用命数が短縮される。When bacteria grow in the cleaning filter, the useful life of the cleaning filter is shortened.
第５図に示すように、浴槽水の循環流路中に消毒薬を
