In recirculating bathtubs and recirculating pools, water is circulated in order to reduce water consumption, and purified water is circulated by providing a filtering device installed in the circulation path and a sterilizing device that disinfects bacteria. I use it. A sterilization apparatus in a conventional circulation filtration apparatus has a cylindrical casing provided with an inlet for introducing water and an outlet for deriving water at both ends, and a spherical permanent at the center of the cylindrical casing. Filled with a mixture of a magnet and ferrite ceramic, wave energy that increases the mineralization of water near the inlet and outlet and creates a state where microorganisms cannot survive, and directly kills Legionella bacteria There is one filled with an aluminum-based material to which wave energy is transferred (for example, see Patent Document 1). In addition, the applicant could not find any prior art documents closely related to the present invention by the time of filing other than the prior art documents specified by the prior art document information described in the present specification. .
JP 2001-293479 A (paragraphs “0015” to “0018”, FIGS. 1 and 2)

上述した従来の循環濾過装置においては、導入口から導入された水がケーシング内を拡散することなく導出口に導かれるため、水が除菌剤に接触する時間が短くなり、除菌剤による除菌作用が充分に行われず、したがって除菌による配管の洗浄作用も期待できないという問題があった。また、導入口から導入された水がケーシング内を拡散することなく導出口に導かれることにより、全ての除菌剤に水が均一に接触しないため、一部の除菌剤のみの除菌作用が早く低下してしまい、他の多くの有効な除菌剤が存在するにもかかわらず除菌剤の交換時期を早くしなければならないという問題があった。   In the conventional circulation filtration device described above, the water introduced from the inlet is guided to the outlet without diffusing inside the casing. There was a problem that the fungus action was not sufficiently performed, and therefore the pipe cleaning action by sterilization could not be expected. In addition, since the water introduced from the inlet is guided to the outlet without diffusing inside the casing, the water does not uniformly contact all the sterilizers, so that only some of the sterilizers are sterilized. However, there was a problem that the replacement time of the disinfectant had to be advanced even though many other effective disinfectants existed.

本発明は上記した従来の問題に鑑みなされたものであり、その目的とするところは、除菌剤による除菌作用および配管の洗浄作用を向上させるとともに、除菌剤の交換時期を可及的に遅らせることにある。   The present invention has been made in view of the above-described conventional problems. The object of the present invention is to improve the sterilizing action by the sterilizing agent and the cleaning action of the pipe, and to change the sterilizing agent as much as possible. There is to delay.

この目的を達成するために、請求項1に係る発明は、水を貯留する循環槽と、この循環槽の吸入口とポンプとの間に設けたヘアーキャッチャーと、前記ポンプと前記循環槽の供給口との間に設けた濾過装置とを備えた循環濾過装置において、前記濾過装置と前記循環槽の供給口との間に除菌装置を設けたものである。   In order to achieve this object, the invention according to claim 1 includes a circulation tank for storing water, a hair catcher provided between the suction port of the circulation tank and a pump, and supply of the pump and the circulation tank. In the circulation filtration device provided with the filtration device provided between the mouth, a sterilization device is provided between the filtration device and the supply port of the circulation tank.

請求項2に係る発明は、請求項1に係る発明において、前記除菌装置を、上方に導入口を有し下方に導出口を有しこれら導入口と導出口との間に通水性を有する上下2つの仕切部材で仕切られた除菌剤収納室が設けられた容器と、前記導入口と前記上方の仕切部材との間に設けられ導入口から導入された水を前記上方の仕切部材に均分に分配する分配手段とによって構成したものである。   The invention according to claim 2 is the invention according to claim 1, wherein the sterilization apparatus has an introduction port on the upper side and a discharge port on the lower side, and has water permeability between the introduction port and the discharge port. A container provided with a disinfectant storage chamber partitioned by two upper and lower partition members, and water introduced from the inlet provided between the inlet and the upper partition member is supplied to the upper partition member. And distributing means for evenly distributing.

請求項3に係る発明は、請求項2に係る発明において、前記導入口を前記容器の中央に設け、前記分配手段を、前記上方の仕切部材を覆い多数の穴が設けられたプレートで形成し、多数の穴の開口面積をプレートの中心から外周に向かって大きく形成したものである。   The invention according to claim 3 is the invention according to claim 2, wherein the introduction port is provided in the center of the container, and the distribution means is formed of a plate that covers the upper partition member and is provided with a number of holes. The opening area of a large number of holes is increased from the center of the plate toward the outer periphery.

請求項4に係る発明は、請求項1ないし3のいずれか1項に係る発明において、前記除菌装置を前記濾過装置と前記循環槽の供給口との間に設けた配管に着脱自在に取り付け、前記除菌装置の上流側と下流側とに第1および第2の開閉弁を設け、前記第1の開閉弁の上流側と前記第2の開閉弁の下流側とを接続した除菌装置迂回用の配管を備え、この除菌装置迂回用の配管に第3の開閉弁を設けたものである。   The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the sterilization device is detachably attached to a pipe provided between the filtration device and the supply port of the circulation tank. The first and second on-off valves are provided on the upstream side and the downstream side of the sterilization device, and the sterilization device is connected to the upstream side of the first on-off valve and the downstream side of the second on-off valve. A bypass pipe is provided, and a third open / close valve is provided in the sterilization apparatus bypass pipe.

請求項1に係る発明によれば、除菌装置に供給される水は、上流側のヘアーキャッチャーにより粗大汚染物が除去され、さらに濾過装置によって濾過されているため、除菌装置内での粗大汚染物等の詰まりを防止できるので、除菌装置による除菌作用の低下を防止できるとともに、除菌剤の交換時期を遅らせることができる。また、水に含まれる細菌を除菌装置において除菌することにより、細菌の存在に起因して発生する人体の汗や垢等の有機物が配管の内壁に堆積する、いわゆるバイオフィルムの形成を低減できるため、バイオフィルムによる熱交換器の熱効率の低下を防止できるとともに、配管の洗浄作用を向上させることができる。   According to the invention which concerns on Claim 1, since the coarse contaminant is removed by the upstream hair catcher and the water supplied to the sterilization apparatus is further filtered by the filtration apparatus, the coarse in the sterilization apparatus Since clogging of contaminants and the like can be prevented, it is possible to prevent the sterilization action from being lowered by the sterilization apparatus and to delay the replacement period of the sterilization agent. In addition, by sterilizing bacteria contained in water with a sterilization device, the formation of so-called biofilms, in which organic matter such as human sweat and dirt generated due to the presence of bacteria accumulates on the inner wall of the pipe, is reduced. Therefore, it is possible to prevent a decrease in the thermal efficiency of the heat exchanger due to the biofilm and improve the cleaning action of the pipe.

請求項2に係る発明によれば、導入口から容器内に導入された水が上方の仕切部材に均分に分配されるため、水が除菌剤収納室内の除菌剤全体に均分に接触するので、除菌剤による除菌作用が向上するとともに、除菌剤の交換時期を遅らせることができる。   According to the invention of claim 2, since the water introduced into the container from the inlet is equally distributed to the upper partition member, the water is evenly distributed to the entire disinfectant in the disinfectant storage chamber. Since it contacts, the disinfection action by the disinfectant is improved and the replacement time of the disinfectant can be delayed.

請求項3に係る発明によれば、プレートの穴を通過する水は、穴の通過により中央部から半径方向に多くなるように分散して除菌剤中を通過するから、水が全ての除菌剤に対して略均分に接触するので除菌作用が向上する。また、一部の除菌剤のみの除菌作用が早く低下し、他の多くの有効な除菌剤が存在するようなことがなく、全ての除菌剤の除菌作用が略同じ程度に低下するため、除菌剤の交換時期を相対的に遅らせることができる。   According to the invention of claim 3, the water passing through the holes in the plate is dispersed so as to increase in the radial direction from the center by passing through the holes and passes through the disinfectant. Since it contacts the fungicide approximately equally, the disinfection action is improved. In addition, the sterilization effect of only some of the sterilization agents decreases quickly, and there are no other effective sterilization agents. Since it decreases, the replacement time of the disinfectant can be relatively delayed.

請求項4に係る発明によれば、、除菌装置を交換するとき、第1および第2の開閉弁により水の流れを止めることにより、循環系路中の水の流れを止めることなく除菌装置の交換を行うことができる。   According to the invention which concerns on Claim 4, when replacing | excluding a sterilization apparatus, it sterilizes without stopping the flow of the water in a circulation system by stopping the flow of water by the 1st and 2nd on-off valve. The device can be replaced.

次に、図3および図4を用いて除菌装置8の構造について説明する。除菌装置8は、ステンレス板等の耐食性を有する材料によって略有底円筒状に形成された除菌剤収納容器20を備えており、この除菌剤収納容器20の上方の開口20aの端縁にはフランジ21が設けられている。また、この除菌剤収納容器20の底部の中央部には導出口22が設けられ、この導出口22の端縁には筒部23が一体に突設され、この筒部23の下端縁にはフランジ24が設けられている。   Next, the structure of the sterilization apparatus 8 will be described with reference to FIGS. 3 and 4. The sterilization apparatus 8 includes a sterilization agent storage container 20 formed in a substantially bottomed cylindrical shape using a corrosion-resistant material such as a stainless steel plate, and an edge of the opening 20 a above the sterilization agent storage container 20. Is provided with a flange 21. Further, a discharge port 22 is provided at the center of the bottom of the sterilizing agent storage container 20, and a cylindrical portion 23 is integrally projected at the end edge of the discharge port 22. Is provided with a flange 24.

25は全体が通水性を有しかつステンレス板等の耐食性を有する材料からなるパンチングプレート等によって形成された下方の仕切部材であって、導出口22を覆うように除菌剤収納容器20の底部に取り付けられている。26は全体が通水性を有しかつステンレス等の耐食性を有する材料からなるパンチングプレート等によって形成された上方の仕切部材である。ここでの通水性とは、仕切部材25,26から後述する除菌剤38が漏出するのを規制し、仕切部材25,26から浴槽水2の通過を規制しない機能のことをいう。   Reference numeral 25 denotes a lower partition member formed by a punching plate or the like made of a material having water permeability as a whole and having corrosion resistance such as a stainless steel plate, and the bottom of the disinfectant storage container 20 so as to cover the outlet 22 Is attached. Reference numeral 26 denotes an upper partition member formed by a punching plate or the like made of a material having water permeability as a whole and having corrosion resistance such as stainless steel. Here, the water permeability refers to a function that restricts leakage of a sterilizing agent 38 described later from the partition members 25 and 26 and does not restrict passage of the bathtub water 2 from the partition members 25 and 26.

27はステンレス板等の耐食性を有する材料によって略有底円筒状に形成された分配手段としての分配容器であって、底部28と周部29とこの周部29の上端縁に設けられたフランジ30とによって形成されている。この分配容器27の底部28には、図4に示すように、中央部から半径方向に同心円上に形成した浴槽水2が通過する5重の穴群31aないし31eが設けられている。穴群31aないし31eの開口面積は、底部28の中央側に設けられた穴群31aから半径方向に漸次大きく形成されており、最外周に設けられた穴群31eが最も大きく形成されている。また、周部29の外径は、除菌剤収納容器20の内径よりもわずかに小さく形成されている。   Reference numeral 27 denotes a distribution container as a distribution means formed in a substantially bottomed cylindrical shape by a material having corrosion resistance such as a stainless steel plate, and includes a bottom portion 28, a peripheral portion 29, and a flange 30 provided at an upper end edge of the peripheral portion 29. And is formed by. As shown in FIG. 4, the bottom portion 28 of the distribution container 27 is provided with five hole groups 31a to 31e through which the bathtub water 2 formed concentrically in the radial direction from the center portion passes. The opening areas of the hole groups 31a to 31e are formed so as to gradually increase in the radial direction from the hole group 31a provided on the center side of the bottom portion 28, and the hole group 31e provided on the outermost periphery is formed to be the largest. Further, the outer diameter of the peripheral portion 29 is formed slightly smaller than the inner diameter of the disinfectant storage container 20.

32は上流側のフランジ管継手であって、中央部に容器8の導入口32aとなる開口が設けられており、この導入口32aの周縁には、内周部にねじ部が形成された筒部33が立設されている。35は下流側のフランジ管継手であって、中央部に開口36が設けられており、この開口36の周縁には、内周部にねじ部が形成された筒部37が突設されている。   Reference numeral 32 denotes an upstream flange pipe joint, which is provided with an opening serving as an inlet 32a of the container 8 at the center, and a cylinder having a threaded portion at the inner periphery at the periphery of the inlet 32a. A portion 33 is erected. Reference numeral 35 denotes a downstream flange pipe joint having an opening 36 at the center, and a cylindrical portion 37 having a threaded portion formed at the inner peripheral portion projects from the periphery of the opening 36. .

次に、このように構成された除菌装置8を配管10に取り付ける方法を説明する。予め、上流側のフランジ管継手32の筒部33のねじ部を上流側の配管10Aのねじ部に螺合させ、上流側のフランジ管継手32を上流側の配管10Aに取り付けるとともに、下流側のフランジ管継手35の筒部37のねじ部を下流側の配管10Bのねじ部に螺合させ、下流側のフランジ管継手35を下流側の配管10Bに取り付けておく。   Next, a method for attaching the sterilization apparatus 8 configured as described above to the pipe 10 will be described. In advance, the threaded portion of the tubular portion 33 of the upstream flange fitting 32 is screwed into the threaded portion of the upstream piping 10A, and the upstream flange fitting 32 is attached to the upstream piping 10A. The threaded portion of the cylindrical portion 37 of the flange fitting 35 is screwed into the threaded portion of the downstream pipe 10B, and the downstream flange fitting 35 is attached to the downstream pipe 10B.

次いで、除菌剤収納容器20の開口20aから除菌剤38を除菌剤収納容器20内に、後述するように、分配容器27を除菌剤収納容器20に取り付けたときに除菌剤収納容器20内に形成される除菌剤収納室40内に除菌剤38が隙間なく充填される量だけ入れる。なお、除菌剤としては、例えば松下金属工業株式会社製のセラシーク21や株式会社カルテックコーワ研究所製のカルサインを用いている。この状態としてから、除菌剤38上に上方の仕切部材26を載置し、分配容器27を除菌剤収納容器20内に嵌入させ、分配容器27のフランジ30を除菌剤収納容器20のフランジ21に載置する。次いで、除菌剤収納容器20のフランジ24と下流側のフランジ管継手35との間にパッキン(図示せず)を挟み、ボルト42とナット43とによってフランジ24をフランジ管継手35に取り付ける。   Next, when the disinfectant storage container 20 is attached to the disinfectant storage container 20 through the opening 20a of the disinfectant storage container 20, and the distribution container 27 is attached to the disinfectant storage container 20 as will be described later, the disinfectant storage is performed. The disinfectant storage chamber 40 formed in the container 20 is put in an amount that allows the disinfectant 38 to be filled without any gaps. In addition, as a disinfectant, for example, Ceraseek 21 manufactured by Matsushita Metal Industries Co., Ltd. or Calcine manufactured by Caltech Kowa Laboratory Co., Ltd. is used. After this state, the upper partition member 26 is placed on the sterilizing agent 38, the distribution container 27 is fitted into the sterilization agent storage container 20, and the flange 30 of the distribution container 27 is attached to the sterilization agent storage container 20. Place on the flange 21. Next, a packing (not shown) is sandwiched between the flange 24 of the disinfectant storage container 20 and the downstream flange fitting 35, and the flange 24 is attached to the flange fitting 35 by the bolt 42 and the nut 43.

しかる後、分配容器27のフランジ30と上流側のフランジ管継手32との間にパッキン(図示せず)を挟み、除菌剤収納容器20のフランジ21と分配容器27のフランジ30とを、ボルト44とナット45とによって上流側のフランジ管継手32に共締めする。この状態で、上方の仕切部材26は、除菌剤38と分配容器27の底部28とによって挟持されることにより移動が規制され、導入口32aと導出口22との間に通水性を有する上下2つの仕切部材26,25で仕切られた除菌剤収納室40が形成される。同時に、分配容器27の底部28と上流側のフランジ管継手32との間に、導入口32aから導入された浴槽水2を一端貯留する貯留空間41が形成され、導入口32aはこの貯留空間41の平面視における中央部に位置付けられている。   After that, a packing (not shown) is sandwiched between the flange 30 of the distribution container 27 and the upstream flange fitting 32, and the flange 21 of the disinfectant storage container 20 and the flange 30 of the distribution container 27 are bolted. 44 and the nut 45 are fastened together with the flange joint 32 on the upstream side. In this state, the movement of the upper partition member 26 is restricted by being sandwiched between the sterilizing agent 38 and the bottom portion 28 of the distribution container 27, and the upper and lower portions having water permeability between the inlet 32 a and the outlet 22. The disinfectant storage chamber 40 partitioned by the two partition members 26 and 25 is formed. At the same time, a storage space 41 is formed between the bottom portion 28 of the distribution container 27 and the upstream flange fitting 32 to store the bathtub water 2 introduced from the introduction port 32a. It is located in the center part in planar view.

このように分配容器27の底部28の中央部に開口面積の小さい穴群31a,31b等が設けられていることにより、底部28の中央部の流路抵抗が半径方向の流路抵抗よりも大きい。したがって、除菌装置8の平面視中央部に設けられた導入口32aから除菌剤収納容器20内に導入される浴槽水2は、穴群31aないし31eの通過により、底部28の中央部から半径方向に多くなるように分散して除菌剤収納室40に流入する。すなわち、底部28の中央部から半径方向への異なる流路抵抗によって、分配容器28内に導入される浴槽水2は、上方の仕切部材26の全体に均分に分配され、除菌剤収納室40内の除菌剤38中を通過する。このため、浴槽水2が全ての除菌剤38に対して略均分に接触するので除菌作用が向上するとともに、一部の除菌剤のみの除菌作用が早く低下し、他の多くの有効な除菌剤が存在するようなことがなく、全ての除菌剤の除菌作用が略同じ程度に低下するため、除菌剤38の交換時期を相対的に遅らせることができる。   Thus, by providing the hole groups 31a and 31b having a small opening area at the center of the bottom 28 of the distribution container 27, the flow resistance at the center of the bottom 28 is larger than the flow resistance in the radial direction. . Therefore, the bath water 2 introduced into the disinfectant storage container 20 from the introduction port 32a provided in the central portion in plan view of the sterilization apparatus 8 is passed from the central portion of the bottom portion 28 by passing through the hole groups 31a to 31e. It is dispersed so as to increase in the radial direction and flows into the disinfectant storage chamber 40. That is, the bath water 2 introduced into the distribution container 28 is equally distributed to the entire upper partition member 26 due to different flow path resistances in the radial direction from the central portion of the bottom portion 28, and the disinfectant storage chamber. It passes through the disinfectant 38 in 40. For this reason, since the bathtub water 2 is contacted almost equally with respect to all the sterilization agents 38, the sterilization effect is improved, and the sterilization effect of only some of the sterilization agents is quickly reduced. The effective disinfectant does not exist and the disinfecting action of all the disinfectants is reduced to substantially the same level, so that the replacement time of the disinfectant 38 can be relatively delayed.

ここで、除菌剤38の除菌作用が低下したと判断されるか、また一定の期間が経過し除菌剤38の交換を行うときは、図2において、第3の開閉弁16を操作して除菌装置迂回用の配管13の管路を開き、この除菌装置迂回用の配管13内を水が通過できる状態とする。次いで、第1および第2の開閉弁11,12を操作して、除菌装置8の上流側の配管10Aおよび下流側の配管10Bの管路を閉じ、上流側の配管10Aから除菌装置8への水の供給を停止するとともに、下流側の配管10Bから除菌装置8へ水が逆流するのを阻止する。この状態としてから、図2において、ボルト44とナット45との螺合を解除するとともに、ボルト42とナット43との螺合を解除し、除菌装置8を上流側の配管10Aと下流側の配管10Bとから取り外す。   Here, when it is judged that the sterilizing action of the sterilizing agent 38 has decreased, or when the sterilizing agent 38 is replaced after a certain period of time, the third on-off valve 16 is operated in FIG. Then, the pipe line of the sterilization apparatus detour pipe 13 is opened, and the water can pass through the sterilization apparatus detour pipe 13. Next, the first and second on-off valves 11 and 12 are operated to close the upstream pipe 10A and the downstream pipe 10B of the sterilization apparatus 8, and the sterilization apparatus 8 from the upstream pipe 10A. Is stopped, and the backflow of water from the downstream pipe 10B to the sterilization apparatus 8 is prevented. In this state, in FIG. 2, the screw 44 and the nut 45 are unscrewed and the bolt 42 and the nut 43 are unscrewed, and the sterilizer 8 is connected to the upstream pipe 10 </ b> A and the downstream side. Remove from the pipe 10B.

このとき、除菌装置迂回用の配管13の管路が開いているため、除菌装置8を通過できなくなった浴槽水2はこの除菌装置迂回用の配管13を通過することができるようになるので、循環濾過装置1による濾過動作を停止させることなく交換作業ができる。   At this time, since the pipe line of the sterilization apparatus bypass pipe 13 is open, the bathtub water 2 that cannot pass through the sterilization apparatus 8 can pass through the sterilization apparatus bypass pipe 13. Therefore, the replacement work can be performed without stopping the filtering operation by the circulation filtering device 1.

また、除菌装置8をヘアーキャッチャー6および濾過装置7の下流側に設けたことにより、除菌装置8に供給される浴槽水2は、上流側のヘアーキャッチャー6により粗大汚染物が除去され、かつ濾過装置7により濾過されているため、除菌装置8内での粗大汚染物等の詰まりを防止できるので、除菌装置8による除菌作用の低下を防止できるとともに、除菌剤38の交換時期を相対的に遅らすことができる。また、浴槽水2に含まれる細菌を除菌装置8において除菌することにより、細菌の存在に起因して発生する浴槽水2に含まれる人体の汗や垢等の有機物が配管10の内壁に堆積する、いわゆるバイオフィルムの形成を低減できるため、バイオフィルムによる熱交換器9の熱効率の低下を防止できるとともに、配管10の洗浄作用を向上させることができる。   In addition, by providing the sterilization device 8 on the downstream side of the hair catcher 6 and the filtration device 7, the bath water 2 supplied to the sterilization device 8 has coarse contaminants removed by the upstream hair catcher 6, Moreover, since it is filtered by the filtering device 7, clogging of coarse contaminants in the sterilizing device 8 can be prevented, so that the sterilizing action can be prevented from being lowered by the sterilizing device 8, and the sterilizing agent 38 can be replaced. The time can be delayed relatively. In addition, by sterilizing bacteria contained in the bathtub water 2 in the sterilization apparatus 8, organic matter such as human sweat and dirt contained in the bathtub water 2 generated due to the presence of the bacteria on the inner wall of the pipe 10. Since the formation of so-called biofilm to be deposited can be reduced, it is possible to prevent the thermal efficiency of the heat exchanger 9 from being lowered by the biofilm and improve the cleaning action of the pipe 10.

図5は本発明の第2の実施の形態における除菌装置のモデル図である。この第2の実施の形態の除菌装置50においては、導入口52が除菌剤収納容器51の上側の一方の側部に設けられており、導出口53が除菌剤収納容器51の下側の他方の側部に設けられている点が、上述した第1の実施の形態と大きく異なる点である。除菌剤収納容器51は直方体に形成された箱状を呈しており、導入口52と導出口53との開口部を除いて密閉され、中央部には、上方の仕切部材54と下方の仕切部材55とに挟まれ、除菌剤38が充填された除菌剤収納室56が設けられている。   FIG. 5 is a model diagram of the sterilization apparatus according to the second embodiment of the present invention. In the sterilization apparatus 50 of the second embodiment, the introduction port 52 is provided on one side on the upper side of the sterilizing agent storage container 51, and the outlet port 53 is located below the sterilization agent storage container 51. The point provided in the other side part of the side is a point greatly different from the above-described first embodiment. The disinfectant storage container 51 has a box shape formed in a rectangular parallelepiped shape, is hermetically sealed except for the opening portions of the inlet port 52 and the outlet port 53, and has an upper partition member 54 and a lower partition at the center. A disinfectant storage chamber 56 that is sandwiched between the members 55 and filled with the disinfectant 38 is provided.

2枚の仕切部材54,55は、全体が通水性を有しかつステンレス等の耐食性を有する材料からなる金網またはパンチングプレート等によって形成されている。ここでの通水性とは、仕切部材54,55から除菌剤38が漏出するのを規制し、仕切部材54,55から浴槽水2の通過を規制しない機能のことをいう。   The two partition members 54 and 55 are formed of a wire mesh or a punching plate made of a material having water permeability as a whole and having corrosion resistance such as stainless steel. Here, the water permeability refers to a function that restricts leakage of the sterilizing agent 38 from the partition members 54 and 55 and does not restrict passage of the bathtub water 2 from the partition members 54 and 55.

導入口52と上方の仕切部材54との間には分配手段57が設けられており、この分配手段57は導入口52側から上方の仕切部材54に向かって延在し、上下方向に間隔をおいて設けられた複数の案内板58によって構成されている。これら複数の案内板58は、導入口52から除菌剤収納容器51内に導入される浴槽水2を、上方の仕切部材54の導入口52に近い部位だけでなく遠い部位にも供給し、上方の仕切部材54全体に浴槽水2を均分に分配する。   Distributing means 57 is provided between the introduction port 52 and the upper partition member 54. The distribution means 57 extends from the introduction port 52 side toward the upper partition member 54, and is spaced apart in the vertical direction. It is comprised by the some guide plate 58 provided in this. The plurality of guide plates 58 supply the bathtub water 2 introduced into the disinfectant storage container 51 from the introduction port 52 not only to the portion close to the introduction port 52 of the upper partition member 54 but also to a far portion. The bathtub water 2 is evenly distributed over the entire upper partition member 54.

このように構成されていることにより、上流側の配管10Aから導入口52に導入された浴槽水2は、分配手段57によって上方の仕切部材54全体に均分に分配される。このため、上方の仕切部材54を通過した浴槽水2は、除菌剤収納室56内に充填された除菌剤38の全体に略均分に接触するため、上述した第1の実施の形態と同様に、除菌剤38による除菌作用が向上するとともに、除菌剤38の交換時期を相対的に遅らすことができる。   With this configuration, the bathtub water 2 introduced from the upstream pipe 10 </ b> A to the introduction port 52 is evenly distributed to the entire upper partition member 54 by the distribution means 57. For this reason, since the bathtub water 2 that has passed through the upper partition member 54 contacts the entire disinfectant 38 filled in the disinfectant storage chamber 56 approximately equally, the first embodiment described above. Similarly, the sterilization effect of the sterilizing agent 38 is improved, and the replacement time of the sterilizing agent 38 can be relatively delayed.

本実施の形態においては、ヘアーキャッチャー6によって粗大汚染物のみを除去するようにしたが、除菌剤38を収容して細菌を除菌するようにしてもよい。   In the present embodiment, only the coarse contaminants are removed by the hair catcher 6, but a disinfectant 38 may be accommodated to disinfect bacteria.
