Description
【０００１】[0001]
本考案は、水道水の蛇口等比較的高圧力の原水供給栓に取り付けて使用する浄 水器の、中空糸膜モジュールの浄水吐出口への浄水吐出量を適量に規制するため に浄水吐出口に挿入して使用する流量調整具に関する。 The present invention is a purified water discharge port for regulating the amount of purified water discharged to the purified water discharge port of a hollow fiber membrane module of a water purifier that is used by being attached to a relatively high pressure raw water supply tap such as a tap water tap. The present invention relates to a flow rate adjusting device to be used by inserting into a device.
【０００２】[0002]
近年、中空糸膜等の微細孔を有した濾過膜を用いたフィルターによって、原水 中の微細な塵や雑菌が除去できることからこのフィルターを用いた浄水器が脚光 を浴び水道水等の浄化に広く用いられつつある。 In recent years, a filter using a filtration membrane with fine pores such as a hollow fiber membrane can remove fine dust and bacteria in raw water, so a water purifier using this filter is widely used for purification of tap water. It is being used.
【０００３】 このようなフィルターは、一般に多孔質中空糸膜の開口端を開口状態に保った まま集束してプラスチック等のケース内部に収納し、前記開口端を樹脂等のポッ テング材で固定すると同時にケース本体とも一体的に接合固定し、ポッテングし た開口端を浄水の吐出部とした中空糸膜モジュールとして活性炭等吸着材と組み 合わせて浄水器として用いられている。In such a filter, generally, the open end of a porous hollow fiber membrane is collected while being kept in an open state and housed in a case made of plastic or the like, and the open end is fixed by a potting material such as resin. At the same time, it is also used as a water purifier in combination with an adsorbent such as activated carbon as a hollow fiber membrane module in which the potted open end is integrally joined and fixed to the case body and the potted open end is used as the purified water discharge part.
【０００４】 これら浄水器の内、水道水の蛇口に直接取り付けて使用するいわゆる蛇口直結 型浄水器は、最近のユーザーの健康意識の高揚につれ、飛躍的な普及状態となっ ている。 このような蛇口直結型の浄水器は、水道水の水圧が直接付加される機構となっ ており、使用者が必要に応じて蛇口の水量調節栓を調節して水量を調整している のが現状である。Among these water purifiers, the so-called faucet direct connection type water purifier, which is directly attached to a tap water tap and used, has been dramatically popularized due to recent heightened health awareness of users. This type of water purifier with a direct connection to the faucet has a mechanism in which the water pressure of tap water is directly applied, and the user adjusts the water volume by adjusting the water volume control tap of the faucet as needed. The current situation.
【０００５】[0005]
しかし、蛇口での水量調節が難しい新タイプの蛇口を使用する場合や、水道水 の水圧が大きい地域において使用する場合など、濾過処理された浄水が浄水器を 介して減圧状で吐出されるために無意識に水量調節栓を開きすぎる傾向があり、 結果的に濾過処理時に必要以上の水圧が加わることが多く濾過水量が多くなり過 ぎ、併用されている活性炭等の吸着材の吸着能力が追いつかないという問題が生 じる。また、高圧による浄水処理は、時には中空糸膜が高圧のため損傷する場合 もあり、中空糸膜モジュールの寿命を縮める要因の一つとなっている。 However, when using a new type of faucet where it is difficult to control the amount of water in the faucet, or in an area where the tap water pressure is high, the filtered purified water is discharged under reduced pressure through the water purifier. Unconsciously, there is a tendency to open the water control valve too much, and as a result, excessive water pressure is often applied during the filtration process, and the amount of filtered water increases, and the adsorbing capacity of the adsorbent such as activated carbon that is used is not sufficient. The problem arises that there is none. Further, the high-pressure water purification treatment sometimes damages the hollow fiber membrane due to the high pressure, which is one of the factors that shorten the life of the hollow fiber membrane module.
【０００６】 この対策として、中空糸膜モジュールの原水注入口の口径を小さくし中空糸膜 モジュール内部への原水の流入量を規制し併せて濾過処理時の水圧を低下させた り、活性炭等吸着材の量を多くすることが考えられるが、高層住宅等においては 、水道水を一旦屋上等の貯水槽に汲み上げて貯蔵し、貯水槽からの降下圧を利用 して各家庭へ分配しているところが多く、このようなところでは上層階での水圧 が極端に低下する可能性があり、原水注入口の口径を小さくすれば濾過水量が低 下し過ぎることになり、使用に支障をきたす場合があり好ましくない。また、活 性炭の量を増加させると、低圧状態下での原水の透過性が低下し逆に濾過性能が 低下する可能性がある。As a measure against this, the diameter of the raw water inlet of the hollow fiber membrane module is reduced to regulate the amount of raw water flowing into the hollow fiber membrane module, reduce the water pressure during filtration, and absorb activated carbon. Although it is possible to increase the amount of timber, in high-rise housing, tap water is once pumped up to a storage tank such as a rooftop and stored, and it is distributed to each household by using the down pressure from the storage tank. However, there is a possibility that the water pressure on the upper floors will drop extremely in such places, and if the diameter of the raw water inlet is made small, the amount of filtered water will drop too much, which may hinder use. There is not preferable. Further, if the amount of activated carbon is increased, the permeability of raw water under low pressure may be decreased, and conversely the filtration performance may be decreased.
【０００７】 また、浄水器に新たに切り替え弁を設けて水量調節すればこの問題は解決する が、蛇口直結型の浄水器の殆どは中空糸膜モジュール交換方式であり、現在使用 されている浄水器の解決策とはならない。[0007] Also, this problem can be solved by newly providing a switching valve in the water purifier to adjust the amount of water, but most of the faucet direct connection type water purifiers are of the hollow fiber membrane module exchange system, and are currently used. It is not a solution for the vessel.
【０００８】 本考案は、このような課題を解決し、簡単な構造でユーザーが容易に操作でき る流量調整具を提供することを目的とするものである。An object of the present invention is to solve the above problems and to provide a flow rate adjusting device which has a simple structure and which can be easily operated by a user.

本考案は、中空糸膜モジュールに設けられた浄水吐出口の口径以下の貫通孔と 、浄水吐出口の口径以上の鍔状部とを有し、浄水吐出口に密着状態で且つ着脱自 在に装着し得るようになした栓状部材からなる中空糸膜モジュール用流量調整具 である。 The present invention has a through hole having a diameter equal to or smaller than the diameter of the purified water discharge port provided in the hollow fiber membrane module, and a collar-shaped portion having a diameter equal to or larger than the diameter of the purified water discharge port.

【作用】 本考案の流量調整具は、蛇口直結型浄水器に用いられる中空糸膜モジュールの 浄水吐出口に外部から挿着して使用するものであり、水道水等の水圧が高い場合 にこの流量調整具を挿着すると、既存の浄水器に設けられている中空糸膜モジュ ールの浄水吐出口よりも小径の浄水吐出口を有した状態のものとなり、原水流入 口から流入する水道水の水量が規制され、中空糸膜モジュールにかかる圧力も低 下する。 従って、この流量調整具の貫通孔の口径を変えたものを準備しておけば必要に 応じた流量調整が可能となる。[Operation] The flow rate adjusting device of the present invention is used by externally inserting it into the clean water discharge port of the hollow fiber membrane module used in the faucet direct connection type water purifier, and is used when the water pressure of tap water is high. When the flow rate adjuster is inserted, the water purification outlet has a diameter smaller than that of the hollow fiber membrane module installed in the existing water purifier, and the tap water flowing in from the raw water inlet The amount of water is regulated and the pressure applied to the hollow fiber membrane module is also reduced. Therefore, the flow rate can be adjusted as needed by preparing the flow rate adjuster with the through hole having a different diameter.
【００１１】 また、浄水処理時の濾過流量が低下してきたときは、貫通孔の口径の大きなも のに取り替えるか、流量調整具を取り外して本来の浄水吐出口をそのまま使用で きる。Further, when the filtration flow rate at the time of the water purification process decreases, the filtration water can be replaced with one having a larger diameter of the through hole, or the flow rate adjusting tool can be removed and the original water purification outlet can be used as it is.

以下本考案の実施態様を図面に従い詳細に説明する。 図１は、本考案の流量調整具の一例を示した斜視図であり、図２は、本考案の 流量調整具を中空糸膜モジュールの浄水吐出口に装着した場合の縦断面図であり 、１は流量調整具、２は貫通孔、３は鍔状部、４は浄水吐出口、５は中空糸膜、 ６は筒状のケース本体をそれぞれ示している。 Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing an example of a flow rate adjusting device of the present invention, and FIG. 2 is a vertical cross-sectional view of the flow rate adjusting device of the present invention mounted on a purified water outlet of a hollow fiber membrane module. Reference numeral 1 is a flow rate adjuster, 2 is a through hole, 3 is a flanged portion, 4 is a purified water discharge port, 5 is a hollow fiber membrane, and 6 is a tubular case body.
【００１３】 本考案の流量調整具１は、主として蛇口直結型の浄水器に活性炭等の吸着材と 共に組み込まれている中空糸膜モジュールに適用されるものであり、ケース本体 ６に浄水吐出口４が設けられている中空糸膜モジュールであれば使用が可能であ る。The flow rate adjuster 1 of the present invention is mainly applied to a hollow fiber membrane module which is incorporated in a faucet direct coupling type water purifier together with an adsorbent such as activated carbon, and a case body 6 has a purified water discharge port. Any hollow fiber membrane module provided with No. 4 can be used.
【００１４】 中空糸膜モジュールとしては、例えばポリオレフィン系やポリスルフォン系の 中空糸膜を親水化処理し集束状としてプラスチック等の筒状のケース本体６に収 納し、収納した中空糸膜５の開口端を開口状に保持した状態でポリウレタン樹脂 等でポッテング処理を施して固定することにより、中空糸膜の中空部を外表面と 機密に仕切ると同時に筒状のケース本体６と接着一体化させて得られる一般に広 く用いられているものがそのまま使用可能である。As the hollow fiber membrane module, for example, a polyolefin-based or polysulfone-based hollow fiber membrane is hydrophilized and bundled into a cylindrical case body 6 made of plastic or the like, and the hollow fiber membrane 5 is stored. While holding the open end in an open shape, by fixing it by potting with polyurethane resin, etc., the hollow part of the hollow fiber membrane is separated from the outer surface as a secret, and at the same time bonded and integrated with the cylindrical case body 6. The widely used products obtained from the above can be used as they are.
【００１５】 一般に用いられている蛇口直結型浄水器に収納されている中空糸膜モジュール に設けられている浄水吐出口４には、水道水の水圧や浄水器としての必要な濾過 流量等を考慮して５〜１０ｍｍ程度の口径の孔が設けられている。本考案の流量 調整具にはその口径よりも小さい口径の孔が設けられており、実験結果では通常 の圧力（３ｋｇ／ｃｍ2 ）の水道水を用いる場合では、２ｍｍ程度の口径でも３ リットル／分程度の十分な濾過流量が得られている。 この場合、流量調整具の口径を浄水吐出口４の口径以下の範囲としたものを数 種類準備しておき、濾過流量の低下に応じて順次浄水吐出口４の口径に近いもの を装着すれば絶えず一定の濾過流量を得ることができる。The purified water discharge port 4 provided in the hollow fiber membrane module housed in the commonly used faucet direct connection type water purifier takes into consideration the water pressure of tap water and the required filtration flow rate as a water purifier. Then, a hole having a diameter of about 5 to 10 mm is provided. The flow rate adjusting device of the present invention is provided with a hole having a diameter smaller than that of the device. According to the experimental results, when tap water of normal pressure (3 kg / cm 2 ) is used, even if the diameter is about 2 mm, 3 liter / A sufficient filtration flow rate of about a minute is obtained. In this case, prepare several kinds of flow rate adjusters whose diameters are within the range of the purified water discharge port 4 or less, and install the ones that are close to the diameter of the purified water discharge port 4 in sequence as the filtration flow rate decreases. It is possible to obtain a constantly constant filtration flow rate.
【００１６】 本考案の流量調整具は形状として、図１に示されているように中心部に上述し たような貫通孔２を有しており、更に、装着した際に流量調整具が必要以上に筒 状のケース６の内部に装着されるのを防止するため、及び着脱を容易とするため の鍔状部３が端部に設けられている。As shown in FIG. 1, the flow rate adjusting device of the present invention has a through hole 2 as described above at the center as shown in FIG. 1, and further requires a flow rate adjusting device when mounted. As described above, the flange portion 3 is provided at the end portion to prevent the tubular case 6 from being mounted inside and to facilitate the attachment / detachment.
【００１７】 この流量調整具に用いられる栓状部材としては、プラスチック、木材、金属等 各種の部材のものの使用が可能であるが、プラスチック等柔軟性と弾性とを有す る部材を使用すれば、着脱が容易となり好ましい。 この場合、装着部にゴム製のパッキン等を併用すれば流量調整具の装着をより 完全にすることが可能となる。As the plug-like member used in this flow rate adjusting device, various members such as plastic, wood, and metal can be used, but if a member having flexibility and elasticity such as plastic is used. It is preferable because it can be easily attached and detached. In this case, if a rubber packing or the like is also used in the mounting portion, the flow rate adjuster can be mounted more completely.
