Description of the Related Art Recently, a bathtub in which hot water in a bathtub is pumped up by a circulation pump to forcefully circulate the bathtub hot water circulation passage in which various cleaning treatment devices are provided and to eject the purified water into the bathtub again. A hot water purifier has been developed.
【０００３】従来の装置では汚れを取り除くための濾過

わゆる濾過タンクが配備され、汚れを濾過と同時に吸着
やイオン交換によって取り除くようにしている。In the conventional apparatus, a so-called filtration tank in which a filtration layer is formed by a granular filtration material having an adsorption power of activated stone, activated carbon, zeolite and the like and an ion exchange capacity is provided as a filtration device for removing dirt, and the dirt is removed. At the same time as filtration, it is removed by adsorption or ion exchange.

【発明が解決しようとする課題】浴槽湯中の汚れには湯
中に浮遊する単なる毛や垢だけでなく、身体からの分泌
物、石鹸、化粧品、塗り薬等の身体への付着物、原水中
の不溶解成分その他様々な汚れがある。Dirt in the bathtub is not limited to mere hair and dirt floating in the bathtub, but also secretions from the body, soaps, cosmetics, patches on the body such as ointment, and raw water. There are various insoluble components and other stains.
【０００６】これらの汚れの内、粒径10-6以上の大きな
汚れは糸巻きフイルタや粒状濾材の濾過層の濾過能力に
より問題なく濾過でき、また粒径10-9以下の極めて微細
な汚れや溶解している汚れは粒状濾材の吸着力やイオン
交換能力等によって取り除ける。Among these stains, large stains having a particle size of 10 -6 or more can be filtered without problems due to the filtering ability of the filter layer of the wound filter or the granular filter medium, and extremely fine dirt having a particle size of 10 -9 or less or dissolved. The stains can be removed by the adsorption power of the granular filter material, the ion exchange capacity, and the like.
【０００７】しかしながら、従来の装置は濾材がすぐに

ロイド粒子の汚れは取り除くのが難しく、しかもこのコ
ロイド粒子となった汚れが湯中に多く分散すると湯が白
く濁り、入浴者にとっては非常に不快となる。However, since the conventional apparatus does not use a filter material having a fine mesh so that the filter material will not be clogged immediately or give a great resistance to the flow of hot water, insoluble components in these stains will be It is difficult to remove stains from colloidal particles with a particle size of 10 -6 to 10 -9, which are aggregated, and if a large amount of these colloidal particles are dispersed in hot water, the hot water will turn white and turbid, which is very dangerous for bathers. Becomes uncomfortable.

体のような精密濾材を用いれば取り除ける。[0008] Such dirt that has become colloidal particles can be removed if the filter medium becomes clogged as the apparatus is operated, and if a precision filter medium such as a hollow fiber or a high density sintered body is used as the filter medium. Can be removed.
【０００９】しかし濾材の目詰まりによる濾過を期待し

のを我慢しなければならず、また精密濾材を利用すると
濾材の抵抗により通常の循環ポンプでは湯を循環できず
特別の加圧装置が必要となって、装置が大型で高価なも
のになる。However, in expectation of filtration due to clogging of the filter medium, it is necessary to endure that the hot water becomes cloudy until the filter medium is clogged, and if a precision filter medium is used, the resistance of the filter medium causes the usual The circulation pump cannot circulate hot water and requires a special pressurizing device, which makes the device large and expensive.
【００１０】さらに精密濾材はかなり微細な汚れまで濾

する浴槽湯の清浄化方法である。That is, according to the present invention, the hot water in the bathtub is pumped up by a circulation pump, and the hot water is cleaned by forcibly circulating the circulation path of the bathtub hot water in which various cleaning devices are installed. In the bath water purifying device that re-ejects water into the bathtub, a microfiltration tank for microfiltration is provided in the sub-circulation path that branches from the main circulation path where the purification treatment equipment is arranged in series via the switching valve. In the bath water purifying device, the microfiltration tank is equipped with a microfiltration medium and is provided with a pressurizing device. In addition, in the bath water purifying device that branches from the main circulation route of the bath water to the sub-circulation route where a microfiltration tank is installed via a switching valve, the bath water detected by the turbidity sensor is controlled by the control device. Automatic switching valve according to turbidity Instead, the hot water is circulated including the sub-circulation path, and in addition to the normal cleaning treatment, the micro-filtration tank installed in the sub-circulation path is used for microfiltration treatment. is there.

【発明の作用】本発明は前記したように構成され、通常
は湯を主循環路循環させて清浄化処理し、湯が白濁した
時に限って、切換弁の切り換えにより主循環路から分岐
した副循環路をも湯が循環するようにする。The present invention is constructed as described above, and normally, hot water is circulated in the main circulation path for cleaning treatment, and only when the hot water becomes cloudy, a sub valve branched from the main circulation path by switching the switching valve. Make sure that hot water circulates in the circulation path.

汚れが取り除かれ、湯が白濁した際には精密濾過タンク
での濾過も実施されコロイド粒子の汚れも取り除かれ、
白濁がなくなったなら再び切換弁を切り換えて、湯は主
循環路だけを循環させて清浄化処理をするようにする。As a result, dirt is usually removed by a conventional filtration device, and when the hot water becomes cloudy, filtration in a microfiltration tank is also carried out to remove dirt on the colloidal particles.
When the white turbidity disappears, the switching valve is switched again, and the hot water is circulated only in the main circulation path for cleaning treatment.

濾材はすぐには目詰まりしないし、装置の運転中でも濾
材を取り出して洗浄できるので濾材の寿命を延ばせ、濾
材が高くてもそれほどランニングコストは掛からない。Therefore, since the filtration in the microfiltration tank provided in the sub-circulation path is limited when the hot water becomes cloudy, the microfiltration medium does not immediately become clogged, and the filtration medium can be taken out and washed even while the apparatus is in operation. The life of the filter medium can be extended, and even if the filter medium is high, the running cost is not so high.
【００１６】また、精密濾過する場合は加圧が必要であ
るが、装置全体を加圧しないでも、精密濾過タンクに設
けた安くて簡便な加圧装置で精密濾過タンクだけを加圧
して容易に精密濾過できる。Further, although pressure is required for microfiltration, it is easy to press only the microfiltration tank with a cheap and simple pressurizing device provided in the microfiltration tank without pressurizing the entire apparatus. Can be microfiltered.
【００１７】さらに、切換弁の切り換えを濁度センサが

目詰まりさせない。Furthermore, if the switching valve is automatically switched according to the turbidity of the hot water detected by the turbidity sensor, the dirt can be removed from the initial stage when a slight amount of white turbidity occurs, which facilitates microfiltration. When the dirt is removed, the microfiltration is automatically completed, so the microfiltration is not unnecessarily performed and the filter material is not clogged quickly.
