Note that parts having the same configuration and operation as those of the prior art are denoted by the same reference numerals, and detailed description thereof is omitted.

図１は浴槽８の断面図、図２は浴槽８の平面図である。上記浴槽８は、長さＬ２が短い（例えば１４００ｍｍ）小型の浴槽であって、従来と同様に、長手方向の一方に給水カラン２が設けられている。なお、５は浴室の壁、６は洗い場である。   FIG. 1 is a sectional view of the bathtub 8, and FIG. 2 is a plan view of the bathtub 8. The bathtub 8 is a small bathtub having a short length L2 (for example, 1400 mm), and the water supply currant 2 is provided on one side in the longitudinal direction as in the conventional case. 5 is a bathroom wall and 6 is a washing place.

上記浴槽８の長手方向の他方の内部にスペースＳ２が形成されるとともに、長手方向の一方の内部にスペースＳ２が形成されている。この各スペースＳ２は、従来のスペースＳ１の約半部程度であって、このスペースＳ２の幅が狭いために、内部にポンプ３や気液接触タンク４を従来のようにまとめて配置することができない。   A space S2 is formed inside the other longitudinal direction of the bathtub 8, and a space S2 is formed inside one longitudinal direction. Each space S2 is about a half of the conventional space S1, and since the width of the space S2 is narrow, the pump 3 and the gas-liquid contact tank 4 can be collectively arranged as in the conventional case. Can not.

そこで、図２に示したように、上記ポンプ３は、浴槽８の長手方向の一方の角（コーナー）部８ａ内に配置するとともに、上記気液接触タンク４は、浴槽８の長手方向の他方の角（コーナー）部８ｂ内に配置する。すなわち、スペースＳ２自体の幅は狭いものの、角（コーナー）部８ａ，８ｂの対角部分は、比較的広くなるので、ポンプ３と気液接触タンク４とそれぞれ配置することが可能である。   Therefore, as shown in FIG. 2, the pump 3 is disposed in one corner (corner) portion 8 a in the longitudinal direction of the bathtub 8, and the gas-liquid contact tank 4 is disposed in the other longitudinal direction of the bathtub 8. It arrange | positions in the corner | angular (corner) part 8b. That is, although the width of the space S2 itself is narrow, the diagonal portions of the corner portions 8a and 8b are relatively wide, so that the pump 3 and the gas-liquid contact tank 4 can be arranged respectively.

上記ポンプ３は、浴槽８の長手方向の他方の角（コーナー）部８ｂ内に配置するとともに、上記気液接触タンク４は、浴槽８の長手方向の一方の角（コーナー）部８ａ内に配置することも可能である。   The pump 3 is disposed in the other corner (corner) portion 8 b in the longitudinal direction of the bathtub 8, and the gas-liquid contact tank 4 is disposed in one corner (corner) portion 8 a in the longitudinal direction of the bathtub 8. It is also possible to do.

上記ポンプ３と気液接触タンク４とは、奥壁側の角部８ａ´，８ｂ´ではなく、洗い場６側の角部８ａ，８ｂ内に配置することが好ましい。   The pump 3 and the gas-liquid contact tank 4 are preferably arranged not in the corners 8a 'and 8b' on the back wall side but in the corners 8a and 8b on the washing place 6 side.

図１に示すように、浴槽８の洗い場６側の浴槽壁８ｃには吸込口９と吐出口１０とが形成されている。上記ポンプ３と気液接触タンク４とは、これらの吸込口９と吐出口１０よりも高い位置に配置されている。   As shown in FIG. 1, a suction port 9 and a discharge port 10 are formed in the bathtub wall 8 c on the washing place 6 side of the bathtub 8. The pump 3 and the gas-liquid contact tank 4 are arranged at positions higher than the suction port 9 and the discharge port 10.

上記吸込口９は、接続管２０を介して空気吸引部（エゼクタ−）１１の入口に接続され、この空気吸引部１１の出口は、接続管２１を介して上記ポンプ３に接続されている。   The suction port 9 is connected to an inlet of an air suction part (ejector) 11 via a connection pipe 20, and an outlet of the air suction part 11 is connected to the pump 3 via a connection pipe 21.

上記浴槽８のフランジ部８ｄの裏面には、逆止弁１２と絞り弁１３とフィルター１４とで３段構成された空気取入れ部１５が設置され、この空気取入れ部１５は、接続管２２を介して上記空気吸引部１１の側部に接続されている。   On the back surface of the flange portion 8 d of the bathtub 8, an air intake portion 15 composed of a check valve 12, a throttle valve 13, and a filter 14 is installed, and the air intake portion 15 is connected via a connecting pipe 22. Connected to the side of the air suction unit 11.

上記ポンプ３は、接続管２３を介して上記気液接触タンク４の上部に設けられた噴霧ノズル１６に接続されていて、この気液接触タンク４には、空気抜き弁１７が設けられている。   The pump 3 is connected to a spray nozzle 16 provided in the upper part of the gas-liquid contact tank 4 via a connecting pipe 23, and an air vent valve 17 is provided in the gas-liquid contact tank 4.

上記気液接触タンク４の下部は、接続管２４を介して上記吐出口１０に接続され、この接続管２４の途中には、減圧弁１８が介設されている。   The lower part of the gas-liquid contact tank 4 is connected to the discharge port 10 via a connecting pipe 24, and a pressure reducing valve 18 is provided in the middle of the connecting pipe 24.

上記接続配管２０〜２４および関連機器類１１，１５，１８は、上記吸込口９と吐出口１０と同様に、浴槽８の洗い場６側にまとめて設けられているのが好ましい。また、上記接続配管２０〜２４および関連機器類１１，１５，１８は、上記ポンプ３と気液接触タンク４と同様に、吸込口９と吐出口１０よりも高い位置に配置されているのが好ましい。   The connection pipes 20 to 24 and the related devices 11, 15, and 18 are preferably provided together on the washing place 6 side of the bathtub 8, similarly to the suction port 9 and the discharge port 10. Further, the connection pipes 20 to 24 and the related equipments 11, 15, and 18 are arranged at positions higher than the suction port 9 and the discharge port 10, similarly to the pump 3 and the gas-liquid contact tank 4. preferable.

上記のように微細気泡発生装置を備えた浴槽８を構成すれば、スイッチ操作でポンプ３を駆動すれば、吸込口９から接続管２０，２１を介して浴槽８内の浴水がポンプ３に吸水されるとともに、その途中で、空気吸引部（エゼクタ−）１１の負圧作用により空気取入れ部１５から取入れられた空気が浴水に混入されるようになる。   If the bathtub 8 provided with the fine bubble generating device is configured as described above, the bath water in the bathtub 8 is supplied to the pump 3 from the suction port 9 through the connection pipes 20 and 21 if the pump 3 is driven by a switch operation. In the middle of the water absorption, air taken in from the air intake 15 is mixed into the bath water by the negative pressure action of the air suction part (ejector) 11.

そして、空気が混入された浴水は、ポンプ３から接続管２３を介して噴霧ノズル１６から気液接触タンク４内に噴出されることでバブリング状態となる。この気液接触タンク４内の余剰空気は、空気抜き弁１７からタンク外部に排出される。   Then, the bath water mixed with air is jetted from the spray nozzle 16 into the gas-liquid contact tank 4 through the connection pipe 23 from the pump 3 to enter a bubbling state. Excess air in the gas-liquid contact tank 4 is discharged from the air vent valve 17 to the outside of the tank.

この気液接触タンク４内の浴水は、減圧弁１８で白濁の濃い微細気泡を含む浴水に変換されながら、吐出口１０から浴槽８内に吐出されるようになる。   The bath water in the gas-liquid contact tank 4 is discharged into the bathtub 8 from the discharge port 10 while being converted into bath water containing white fine cloudy bubbles by the pressure reducing valve 18.

このような浴水の循環を繰り返すことで浴槽８内は、微細気泡の浴水で満たされるようになる。   By repeating such circulation of the bath water, the inside of the bathtub 8 is filled with bath water with fine bubbles.

上記構成において、浴槽８の長手方向の一方の角部８ａ内にポンプ３を配置し、他方の角部８ｂ内に気液接触タンク４を配置したから、角部８ａ，８ｂの対角部分を有効に利用してポンプ３と気液接触タンク４とを振り分け配置できるので、長さＬ２が短い小型の浴槽８にも採用できるようになった。   In the above configuration, since the pump 3 is disposed in one corner 8a in the longitudinal direction of the bathtub 8, and the gas-liquid contact tank 4 is disposed in the other corner 8b, the diagonal portions of the corners 8a and 8b are arranged. Since the pump 3 and the gas-liquid contact tank 4 can be distributed and arranged effectively, it can be adopted for a small bathtub 8 having a short length L2.

また、ポンプ３と気液接触タンク４とを洗い場６側の角部８ａ，８ｂ内に配置したから、洗い場６側の浴槽エプロンの点検口から、ポンプ３と気液接触タンク４とを容易に保守点検できるようになった。   Further, since the pump 3 and the gas-liquid contact tank 4 are disposed in the corners 8a and 8b on the washing place 6 side, the pump 3 and the gas-liquid contact tank 4 can be easily connected from the inspection opening of the bathtub apron on the washing place 6 side. Maintenance inspection is now possible.

さらに、吸込口９、吐出口１０、接続配管２０〜２４および関連機器類１１，１５，１８を浴槽８の洗い場６側に設けたから、洗い場６側の浴槽エプロンの点検口から、吸込口９、吐出口１０、接続配管２０〜２４および関連機器類１１，１５，１８を容易に保守点検できるようになった。   Furthermore, since the suction port 9, the discharge port 10, the connection pipes 20 to 24, and the related equipments 11, 15, and 18 are provided on the washing place 6 side of the bathtub 8, from the inspection opening of the bathtub apron on the washing place 6 side, The discharge port 10, the connecting pipes 20 to 24, and the related equipments 11, 15, and 18 can be easily inspected and maintained.

また、ポンプ３と気液接触タンク４、接続配管２０〜２４および関連機器類１１，１５，１８を吸込口９と吐出口１０よりも高い位置に配置したから、浴槽８から浴水を排水するときに、これらの内部に残水が残らないので、衛生的である。   Moreover, since the pump 3, the gas-liquid contact tank 4, the connection pipes 20 to 24, and the related equipments 11, 15, 18 are arranged at positions higher than the suction port 9 and the discharge port 10, the bath water is drained from the bathtub 8. Sometimes there is no residual water inside these, so it is hygienic.
