本考案は水道等の蛇口に接続して用いる浄水器
用の水抜き弁に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drain valve for a water purifier that is connected to a faucet or the like.
水道の蛇口に接続する浄水器としては従来より
活性炭を充填したものが知られていたが、最近、
活性炭等の吸着材と中空糸過膜とを組み合わせ
た浄水器が上市されており（実願昭59−107172号
等参照）、活性炭単独では除去できない細菌類、
有機物、コロイド等を除去できることから市場に
おいてその優秀性が認められつつある。
Water purifiers that are connected to taps have traditionally been filled with activated carbon, but recently,
Water purifiers that combine adsorbents such as activated carbon and hollow fiber membranes are on the market (see Utility Model Application No. 107172/1983), and they can remove bacteria and bacteria that cannot be removed with activated carbon alone.
Its superiority is being recognized in the market because it can remove organic matter, colloids, etc.
しかし、このような活性炭と中空糸過膜を有

積される場合があり、それが原因となつて不快臭
発生等の問題が起こる可能性がある。 However, although such water purifiers with activated carbon and hollow fiber membranes have the advantage of being able to filter out bacteria, etc., the activated carbon layer and hollow fiber membrane layer are removed from the inlet side of the water to be purified. In water purifiers that are arranged in this order, the activated carbon layer removes the disinfectant component in the water, so depending on the water quality of the water to be purified and the frequency of use of the water purifier, the water side of the hollow fiber filtration membrane may be Bacteria may accumulate excessively on the surface without being killed, which may cause problems such as unpleasant odors.
臭気発生物質としては、たとえば硫酸塩還元菌
によつて生成される硫化水素を挙げることがで
き、この菌は嫌気性雰囲気において増殖する。 Odor-producing substances include, for example, hydrogen sulfide produced by sulfate-reducing bacteria, which grow in an anaerobic atmosphere.
水道水中にはある程度の酸素が溶存しており、
浄水器の使用中は水道水を介して浄水器内に酸素
が供給されるので浄水器内の環境は好気的であ
る。ところが浄水器の使用が停止すると水道水を
介しての酸素の供給が止まるので浄水器内は酸素
不足となり、硫酸塩還元菌等の嫌気性菌が増殖可
能な環境になる。 There is a certain amount of oxygen dissolved in tap water.
While the water purifier is in use, oxygen is supplied into the water purifier via tap water, so the environment inside the water purifier is aerobic. However, when the water purifier stops being used, the supply of oxygen through tap water stops, resulting in a lack of oxygen inside the water purifier, creating an environment in which anaerobic bacteria such as sulfate-reducing bacteria can grow.
嫌気性菌の増殖を抑制するためには、浄水器内
を好気性雰囲気にすればよく、たとえば使用停止
時において浄水器内の水を抜いて浄水器内に空気
を導入する方法を採用することができる。 In order to suppress the growth of anaerobic bacteria, it is sufficient to create an aerobic atmosphere inside the water purifier; for example, when the water purifier is not in use, the water in the water purifier is drained and air is introduced into the water purifier. I can do it.
水抜き弁として採用可能な構造を有する弁とし
て、ニードル弁やボール弁等を用いて手動で作動
させるものを挙げることができるが、手動の弁は
操作が煩わしく、弁の開け忘れや閉め忘れ等の誤
操作が起こる可能性があり好ましくない。 Valves with a structure that can be used as drain valves include those that are operated manually using needle valves, ball valves, etc., but manual valves are cumbersome to operate, and there are cases where you forget to open or close the valve. This is undesirable as it may lead to incorrect operation.

点等が問題である。 Therefore, from the viewpoint of operability, it is preferable to have a structure that operates automatically, and an example of this is a drain valve that uses a combination of a spring and a ball valve to automatically operate in response to changes in water pressure. Problems include the risk that the spring and ball valve will rust, and the risk that the operation of the valve will be obstructed by dust.
本考案の目的は、被浄化水の水質が悪い時や使

Pressure deformed by water pressure,
As shown in FIG. 6, the drain valve is in the closed state. Next, when the water faucet is closed and the water supply to the water purifier is stopped, the water pressure inside the water purifier decreases, and when this drops below the operating pressure, the rubber valve 1 contacts the rubber valve seat as shown in Figure 5. Since it is separated from the surface 7, the water in the water purifier flows through the notch 2 of the rubber valve and the drain port 8 in the direction of the arrow in FIG.

以下、実施例により更に具体的に説明する。 Hereinafter, this will be explained in more detail with reference to Examples.
実施例 １
外径６mmφ、厚み0.5mmのシリコンゴム製円板

径は２mmφ、ゴム弁把持部の内径は６mmφとし
た。Example 1 A rubber valve having a notch having the same structure as that shown in FIG. 1 was manufactured by cutting out four semi-cylindrical parts on the peripheral edge of a silicone rubber disk with an outer diameter of 6 mmφ and a thickness of 0.5 mm to form a semi-cylindrical shape with a diameter of 2 mmφ. The valve seat had the same structure as shown in Fig. 5, the rubber valve contact surface was machined into a spherical shape with a radius of 6 mm, the diameter of the drain port was 2 mmφ, and the inner diameter of the rubber valve grip was 6 mmφ.

結果よりこの水抜き弁の作動圧力が約0.1Kg／cm2
であることがわかる。 In order to investigate the operating pressure of the drain valve thus manufactured, the drain valve was attached to the bottom of a cylindrical container with an inner diameter of 5 cmφ and a depth of 150 cm with the hose port facing downward. When this cylindrical container was filled with water, the drain valve was closed and no water flowed out from the drain valve. Next, water was gradually taken out from the top of the cylindrical container, and when the water depth reached 100 cm, the drain valve opened and water flowed out from the hose mouth, and the water in the cylindrical container was completely drained. From the above results, the operating pressure of this drain valve is approximately 0.1Kg/cm 2
It can be seen that it is.

エチレン製のものを用いた。 This drain valve was attached to the bottom of the water purifier shown in FIG. 10 by means of a threaded portion 9. The water purifier consists of an activated carbon layer 26 and a hollow fiber membrane layer 28 placed above it.
There is a water inlet to be purified 2 at the bottom of the water purifier body.
2 had a structure having a purified water outlet 31 at the top, the main body had an outer diameter of 15 cmφ and a height of 30 cm, and the hollow fiber filtration membrane was made of hydrophilic polyethylene.
次に被浄化水導入配管２１を介して浄水器を水
道の蛇口と接続した後、水道の蛇口を開けたとこ
ろ、浄水器本体の上部の浄化水出口ノズル３２か
らのみ水が流出した。 Next, when the water purifier was connected to a water faucet via the water introduction pipe 21 to be purified and the water faucet was opened, water flowed out only from the purified water outlet nozzle 32 at the top of the water purifier main body.
この状態をしばらく続けた後、水道の蛇口を締
め浄水器内の水圧を低下させたところ、水抜き弁
２０が作動し、排水ホース３３を通つて、浄水器
内の水が排出された。 After this state continued for a while, the water faucet was turned on to reduce the water pressure inside the water purifier, and the drain valve 20 was activated and the water inside the water purifier was discharged through the drain hose 33.
本考案の水抜き弁は以下に掲げる優れた効果を
有している。
The drain valve of the present invention has the following excellent effects.
(1) ゴム弁と弁座の接触面の間にゴミが詰まつて
もゴム弁が容易に変形するので、弁の閉鎖が確
実に行なわれ、信頼性が高い。(1) Even if dirt gets stuck between the contact surface of the rubber valve and the valve seat, the rubber valve is easily deformed, so the valve closes reliably and is highly reliable.
(2) ゴム弁の加工が容易であるので作動圧力範囲
の広いものの製作が可能であり、低作動圧力の
弁であつても精度良く加工できる。(2) Since rubber valves are easy to process, they can be manufactured with a wide operating pressure range, and even valves with low operating pressure can be processed with high precision.
(3) 構造が簡単であるので故障が少なく、仮に故
障した場合でも修理が容易であり、ゴム弁の交
換も容易である。(3) Since the structure is simple, there are few failures, and even if a failure occurs, it is easy to repair, and the rubber valve is easy to replace.
(4) スプリングとボール弁併用方式のものと比較
すると低価格で製作できる。(4) It can be manufactured at a lower cost compared to the spring and ball valve combined method.
