Description

【０００１】
【発明の属する技術分野】
本発明は、浴槽水を便器洗浄水として再利用する浴槽水再利用装置における貯水タンクの攪拌装置に関するものである。
【０００２】
【従来の技術】
従来、浴槽から排出される浴槽水を貯水タンクに導いて貯留し、便器使用時に給水ポンプにより貯水タンクに貯留された浴槽水を汲み上げて洗浄水タンクに供給し、便器洗浄水として再利用することが提案されている（例えば、特開平９−３９７９号公報参照）。
【０００３】
すなわち、浴槽水再利用装置１においては、図４に示すように、住宅Ｘの敷地内に貯水タンク２が埋設され、この貯水タンク２には、住宅Ｘの浴室Ｙに設置された浴槽ｙの排水口に一端が接続された導水管３の他端が接続されている。そして、貯水タンク２には給水ポンプ４が付設されており、この給水ポンプ４の吸込口には貯水タンク２の底部に一端が開口された吸込管５の他端が接続されている他、給水ポンプ４の吐出口には、住宅Ｘの便所Ｚに設置された洗浄水タンクｚに一端が接続された供給管６の他端が接続されている。
【０００４】
また、前述した導水管３には、薬剤筒１３を設けた滅菌槽１０が配設されており、薬剤筒１３には、塩素薬剤が収容されている。
【０００５】
したがって、浴槽ｙの浴槽水は、その排水口から導水管３および滅菌槽１０を経て貯水タンク２に貯留される。この際、浴槽水は、滅菌槽１０において、塩素薬剤と接触して溶解させることにより殺菌される。そして、便所Ｚの洗浄水タンクｚに貯留された洗浄水が便器ｚ１の洗浄に使用されると、供給管６の圧力低下を検出して給水ポンプ４を駆動させ、貯水タンク２に貯留された浴槽水を汲み上げて便所Ｚの洗浄水タンクｚに供給する。一方、貯水タンク２の浴槽水が洗浄水タンクｚに供給され、洗浄水タンクｚが満水となると、洗浄水タンクｚの弁（図示せず）が閉じる結果、供給管６の圧力が上昇して給水ポンプ４の駆動を停止させる。
【０００６】
このように、浴槽水再利用装置１は、浴槽ｙからの浴槽水を滅菌槽１０において薬剤筒１３の塩素薬剤で殺菌することにより、貯水タンク２に貯留された浴槽水に雑菌が繁殖するのを防止して浴槽水を便器ｚ１の洗浄水として再利用するものである。
【０００７】
【発明が解決しようとする課題】
ところで、前述した浴槽水再利用装置１においては、浴槽水に含まれる人脂、脂肪酸金属塩、含窒素化合物などの汚濁物質が貯水タンク２において徐々に堆積沈殿し、悪臭の原因となるという問題があった。
【０００８】
なお、給水ポンプ４と洗浄水タンクｚとを接続する供給管６から分岐管を分岐させるとともに、分岐管の他端開口を貯水タンク２の底壁近傍に臨ませることにより、給水ポンプ４を介して貯水タンク２に貯留された浴槽水を洗浄水タンクｚに供給する際、一部の浴槽水を分岐管から貯水タンク２に還流し、その水勢により浴槽水を攪拌して沈殿物を浮遊させ、浮遊した沈殿物を浴槽水とともに吸い込んで洗浄水タンクｚに供給することも提案されている。
【０００９】
しかしながら、貯水タンク２の長さが長くなると、貯水タンク２の長手方向両端において、分岐管から吐出する浴槽水の水勢が弱まり、貯水タンク２に貯留された浴槽水を十分に攪拌し、沈殿物を浮遊させることができない。このため、沈殿物を排出することが困難である。
【００１０】
また、汚濁物質は、貯水タンク２に堆積沈殿するばかりでなく、その周壁にも付着するが、一部の浴槽水を分岐管から貯水タンク２に還流させる程度では、貯水タンク２の周壁に汚濁物質が付着するのを妨げることは困難である。
【００１１】
本発明は、このような問題点に鑑みてなされたもので、便器洗浄水に供給する浴槽水の一部を貯水タンクに還流させて浴槽水を攪拌して沈殿物を浴槽水とともに排出することのできる浴槽水再利用装置における貯水タンクの攪拌装置を提供するものである。
【００１２】
【課題を解決するための手段】
本発明は、浴槽から排出される浴槽水を滅菌槽を経て貯水タンクに貯留し、便器使用時に貯水タンクに貯留された浴槽水を給水ポンプにより汲み上げて洗浄水タンクに供給し、便器洗浄水として再利用する浴槽水再利用装置において、前記給水ポンプと洗浄水タンクとを接続する供給管に分岐管の一端が接続されるとともに、両端にそれぞれ噴射ノズルを設けた攪拌管が貯水タンクの長手方向中間部の底壁近傍で分岐管の他端に接続され、また、噴射ノズルは、貯水タンクの対向する周壁に沿ってその噴射口が互いに逆向きとなるように配置されてなり、給水ポンプを介して貯水タンクに貯留された浴槽水を洗浄水タンクに供給する際、一部の浴槽水を分岐管および攪拌管の各噴射ノズルを介して貯水タンクに還流させ、貯水タンクの浴槽水を攪拌することを特徴とするものである。
【００１３】
この発明によれば、浴槽水を給水ポンプを介して洗浄水タンクに供給する際、一部の浴槽水を分岐管および攪拌管の両端にそれぞれ設けた噴射ノズルを介して貯水タンクに還流させ、その水勢によって浴槽水を攪拌する。ここで、一対の噴射ノズルは、貯水タンクの底壁近傍における対向する周壁に沿うように配置され、かつ、噴射口が互いに逆方向に噴射するように指向されていることから、貯水タンクに還流された浴槽水は、貯水タンクの対向する周壁に沿って噴射ノズルから勢いよく噴射され、貯水タンクの浴槽水をその水勢によって攪拌するものである。この結果、貯水タンクの沈殿物は、浴槽水によって攪拌されて浮遊し、浴槽水とともに吸込管から吸い込まれ、洗浄水タンクに供給される。したがって、貯水タンクに汚濁物質が堆積沈殿することが防止され、悪臭の発生を防止することができるとともに、汚濁物質が周壁に付着するのを防止することができる。
【００１４】
請求項１記載の発明において、攪拌管の近傍に吸込管の他端を配置すると、噴射ノズル近傍の、攪拌効果の大きい浴槽水を吸い込むことができ、より多くの浮遊した沈殿物を吸い込んで排出することができる。
【００１５】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
【００１６】
なお、前述した図４の従来技術に記載された部材と同一の部材については、同一の符号を付してその詳細な説明を省略する。
【００１７】
図１および図２には、本発明の浴槽水再利用装置における貯水タンクの攪拌装置が記載されている。
【００１８】
この攪拌装置は、給水ポンプ４と洗浄水タンクｚとを接続する供給管６から分岐された分岐管８と、両端に噴射ノズル９１を設けて分岐管８の他端に接続された攪拌管９と、から構成されている。そして、分岐管８と攪拌管９との接続部は、貯水タンク２の長手方向約中間部における底壁近傍に位置している。
【００１９】
攪拌管９は、貯水タンク２の底壁近傍に沿って配設され、対向する一対の周壁間に略相当する長さを有している。そして、攪拌管９の両端にそれぞれ設けられた噴射ノズル９１は、それらの噴射口が互いに逆向きとなるように指向されており、このため、貯水タンク２に貯留された浴槽水を、貯水タンク２の長手方向の左半部および右半部においてそれぞれ循環させ、攪拌するものである。
【００２０】
なお、吸込管５は、その吸込口が前述した分岐管８と攪拌管９との接続部の近傍に位置するように配置されている。
【００２１】
したがって、給水ポンプ４を介して貯水タンク２に貯留された浴槽水を洗浄水タンクｚに供給する際、一部の浴槽水を分岐管８および攪拌管９を経て噴射ノズル９１から噴射させると、その水勢により、貯水タンク２に貯留された浴槽水が貯水タンク２の長手方向の半部毎にそれぞれ攪拌されて沈殿物を浮遊させながら流動するものである。このため、汚濁物質が貯水タンク２に堆積沈殿するのを防止するばかりでなく、浮遊させられた沈殿物は、吸込管５を通して浴槽水とともに吸い込まれて洗浄水タンクｚに供給されることから、沈殿物の濃度が一定以上に上昇することを防止することができる。
【００２２】
この場合、噴射ノズル９１は、貯水タンク２の対向する周壁近傍に配置されていることから、噴射ノズル９１から噴射された浴槽水は、貯水タンク２の周壁に沿って流動し、貯水タンク２の周壁内面に汚濁物質が付着するのを防止することができる。
【００２３】
このように構成した攪拌装置の効果を確認するため、下記の要領で試験を実施した。
【００２４】
試験方法としては、貯水タンク２に約２００リットルの水を入れ、懸濁沈殿物の濃度が５ｍｇ／リットルになるように、疑似懸濁沈殿物を約１ｇを入れた後、洗浄水タンクｚから約１０リットル／回の排水を繰り返し行った。５回排水毎に貯水タンク２内の水を採取し、疑似懸濁沈殿物の濃度を測定した。
【００２５】
試験結果を下記の表に示す。
【００２６】

一方、本発明の攪拌装置を設けた貯水タンク２を有する浴槽水再利用装置１Ａについて、図４に示した従来の浴槽水再利用装置１と相違する点を図３に基づいて説明する。
【００２７】
給水ポンプ４と便所Ｚの洗浄水タンクｚ間に配管された供給管６には、電磁切換弁７を配設した分岐管８の一端が接続されており、分岐管８の他端は、前述した攪拌管９に接続されている。この電磁切換弁７は、給水ポンプ４の駆動に同期して開放されるものである。
【００２８】
このため、給水ポンプ４が駆動すると、供給管６の浴槽水は分岐管８および攪拌管９の噴射ノズル９１を通して一部貯水タンク２に還流される結果、前述したように、還流された浴槽水によって貯水タンク２に貯留された浴槽水が攪拌される。また、給水ポンプ４が停止すれば、電磁切換弁７は閉鎖され、貯水タンク２への還流は停止される。
【００２９】
【発明の効果】
以上のように本発明によれば、浴槽水を給水ポンプを介して洗浄水タンクに供給する際、一部の浴槽水を分岐管および攪拌パイプの両端にそれぞれ設けた噴射ノズルを介して貯水タンクに還流させ、その水勢によって浴槽水を攪拌することができる。この結果、貯水タンクの沈殿物は、浴槽水によって攪拌されて浮遊し、浴槽水とともに吸込管から吸い込まれ、洗浄水タンクに供給される他、貯水タンクに汚濁物質が堆積沈殿することが防止され、悪臭の発生を防止することができるとともに、汚濁物質が貯水タンクの周壁に付着することを防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a stirrer for a water storage tank in a bathtub water reuse device that reuses bathtub water as toilet flushing water.
[0002]
[Prior art]
Conventionally, the bathtub water discharged from the bathtub is guided and stored in the storage tank, and when the toilet is used, the bathtub water stored in the storage tank is pumped up by the water supply pump and supplied to the cleaning water tank for reuse as toilet flushing water. Has been proposed (see, for example, JP-A-9-3979).
[0003]
That is, in the bathtub water reuse apparatus 1, as shown in FIG. 4, a water storage tank 2 is embedded in the premises of the house X, and in this water storage tank 2, the bathtub y installed in the bathroom Y of the house X is stored. The other end of the water conduit 3 having one end connected to the drain port is connected. A water supply pump 4 is attached to the water storage tank 2, and the other end of the suction pipe 5 whose one end is opened at the bottom of the water storage tank 2 is connected to the suction port of the water supply pump 4. The discharge port of the pump 4 is connected to the other end of a supply pipe 6 having one end connected to a washing water tank z installed in a toilet Z of a house X.
[0004]
Further, the above-described water conduit 3 is provided with a sterilization tank 10 provided with a drug cylinder 13, and the drug cylinder 13 contains a chlorine drug.
[0005]
Therefore, the bathtub water of the bathtub y is stored in the water storage tank 2 through the water conduit 3 and the sterilization tank 10 from the drain outlet. At this time, the bath water is sterilized in the sterilization tank 10 by dissolving it in contact with the chlorine chemical. Then, when the wash water stored in the wash water tank z of the toilet Z is used for washing the toilet z1, the pressure drop in the supply pipe 6 is detected and the water supply pump 4 is driven to be stored in the water storage tank 2. The bathtub water is pumped up and supplied to the flush water tank z of the toilet Z. On the other hand, when the bathtub water of the water storage tank 2 is supplied to the washing water tank z and the washing water tank z is full, the valve of the washing water tank z (not shown) is closed, resulting in an increase in the pressure of the supply pipe 6. The drive of the feed water pump 4 is stopped.
[0006]
In this way, the bathtub water recycling apparatus 1 sterilizes the bathtub water from the bathtub y with the chlorine chemicals in the drug cylinder 13 in the sterilization tank 10, so that various germs propagate in the bathtub water stored in the water storage tank 2. This prevents water from being reused as washing water for the toilet z1.
[0007]
[Problems to be solved by the invention]
By the way, in the bathtub water reuse apparatus 1 mentioned above, pollutants, such as a human fat, fatty-acid metal salt, and a nitrogen-containing compound contained in bathtub water, deposit and precipitate gradually in the water storage tank 2, and cause a bad odor. was there.
[0008]
The branch pipe is branched from the supply pipe 6 that connects the water supply pump 4 and the washing water tank z, and the other end opening of the branch pipe faces the vicinity of the bottom wall of the water storage tank 2, thereby allowing the water supply pump 4 to pass through. When the bathtub water stored in the storage tank 2 is supplied to the washing water tank z, part of the bathtub water is returned to the storage tank 2 from the branch pipe, and the precipitate is suspended by stirring the bathtub water by the water force. It has also been proposed to suck the suspended sediment together with the bath water and supply it to the washing water tank z.
[0009]
However, when the length of the water storage tank 2 is increased, the water pressure of the bathtub water discharged from the branch pipe is weakened at both ends in the longitudinal direction of the water storage tank 2, and the water stored in the water storage tank 2 is sufficiently agitated and precipitated. Cannot be suspended. For this reason, it is difficult to discharge the precipitate.
[0010]
In addition, the pollutant is not only deposited and settled in the water storage tank 2 but also adheres to the peripheral wall, but to the extent that a part of the bath water is returned to the water storage tank 2 from the branch pipe, it is contaminated on the peripheral wall of the water storage tank 2. It is difficult to prevent substances from adhering.
[0011]
The present invention has been made in view of such problems, and a part of the bathtub water supplied to the toilet flushing water is returned to the water storage tank, the bathtub water is stirred, and the precipitate is discharged together with the bathtub water. The present invention provides a water tank agitation device in a bathtub water reuse device capable of performing the above.
[0012]
[Means for Solving the Problems]
The present invention stores the bathtub water discharged from the bathtub in a water storage tank through a sterilization tank, pumps up the bathtub water stored in the water storage tank when using the toilet bowl by a water supply pump, and supplies it to the washing water tank. In the reused bathtub water recycling apparatus, one end of a branch pipe is connected to a supply pipe connecting the water supply pump and the washing water tank, and stirring pipes provided with injection nozzles at both ends are provided in the longitudinal direction of the water storage tank. Connected to the other end of the branch pipe in the vicinity of the bottom wall of the intermediate portion, and the injection nozzle is arranged so that the injection ports are opposite to each other along the opposing peripheral walls of the water storage tank. When the bathtub water stored in the water storage tank is supplied to the washing water tank, a part of the bath water is returned to the water storage tank through the spray nozzles of the branch pipe and the stirring pipe, It is characterized in that stirring.
[0013]
According to this invention, when supplying the bathtub water to the washing water tank via the water supply pump, a part of the bathtub water is returned to the water storage tank via the injection nozzles provided at both ends of the branch pipe and the stirring pipe, The bathtub water is stirred by the water force. Here, the pair of injection nozzles are arranged along the opposing peripheral walls in the vicinity of the bottom wall of the water storage tank, and the injection ports are directed so as to inject in opposite directions. The bathtub water thus produced is jetted vigorously from the jet nozzle along the opposing peripheral walls of the water storage tank, and the bathtub water in the water storage tank is stirred by the water force. As a result, the sediment in the water storage tank is agitated and floated by the bath water, and is sucked from the suction pipe together with the bath water and supplied to the washing water tank. Therefore, it is possible to prevent the pollutant from depositing and precipitating in the water storage tank, to prevent the generation of malodor, and to prevent the pollutant from adhering to the peripheral wall.
[0014]
In the first aspect of the invention, when the other end of the suction pipe is arranged in the vicinity of the stirring pipe, it is possible to suck in the bathtub water having a large stirring effect in the vicinity of the injection nozzle and suck in and discharge more floating sediment. can do.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
