このような目的のために用いられる浄水器として、特許文献１に示すような浄水器が提案されている。
この浄水器は、活性炭フィルター、セディメントフィルター、ＵＦ膜フィルター一種又は数種、逆浸透膜フィルター、活性炭フィルターを各一つ又は複数を並列、又は直列に濾過部として必要供給飲料水量により複数設け原水を濾過し飲料水を製造する逆浸透膜浄水部と、原水汲み上げ吸水ポンプにより吸水、及び加圧により構成されるものである。 As a water purifier used for such a purpose, a water purifier as shown inPatent Document 1 has been proposed.
This water purifier is equipped with activated carbon filter, sediment filter, one or several types of UF membrane filter, reverse osmosis membrane filter, activated carbon filter one or more in parallel or in series as a filtration unit, and a plurality of raw water provided depending on the amount of required drinking water A reverse osmosis membrane water purification unit for producing drinking water by filtering water, and water absorption and pressurization by pumping up raw water.
この浄水器は、活性炭フィルター、セディメントフィルター、ＵＦ膜フィルター一種又は数種、逆浸透膜フィルター、活性炭フィルターを各一つ又は複数を並列、又は直列に濾過部として必要供給飲料水量により複数設け原水を濾過し飲料水を製造する逆浸透膜浄水部と、原水汲み上げ吸水ポンプにより吸水、及び加圧により構成されるものである。 As a water purifier used for such a purpose, a water purifier as shown in
This water purifier is equipped with activated carbon filter, sediment filter, one or several types of UF membrane filter, reverse osmosis membrane filter, activated carbon filter one or more in parallel or in series as a filtration unit, and a plurality of raw water provided depending on the amount of required drinking water A reverse osmosis membrane water purification unit for producing drinking water by filtering water, and water absorption and pressurization by pumping up raw water.
この浄水器によれば、動力として送電線による電源、内燃機関、太陽電池、交流電源、又は発電機による直流電源の何れも起動可能で、一体化され汎用性を有し原水から不純物を限りなく除去し安全かつ容易に水質基準適合の飲料水を製造できる、とされている。

The inner head 35 has an L-shaped first water passage 36 that communicates with the water inlet port 32 at a rotational position, and an L-shape that communicates with the water outlet port 33 and / or the wash water outlet 34 at the same rotational position. A second water passage 37 is provided.
以下、図２に沿って各モードの流水経路をたどって説明することにする。
図２（ａ）は入水前の断水状態であり、濾材ユニット２０を収容した本体容器１０を装着する前の流水経路の状態である。図２（ｂ）は本体容器１０を新しく装着して、あるいは、しばらく使用していなかった後での再使用時の濾材ユニット２０の洗浄中での流水経路の状態である。図２（ｃ）は浄水作業を連続して行っている状態での流水経路の状態である。 Hereinafter, the flow path of each mode will be described along FIG.
FIG. 2A shows a water cut-off state before entering water, and is a state of a flowing water path before mounting themain body container 10 containing the filter medium unit 20. FIG. 2B shows a state of a flowing water path during cleaning of the filter medium unit 20 when the main body container 10 is newly installed or reused after not being used for a while. FIG.2 (c) is the state of the flowing water path in the state which performs the water purification operation | work continuously.
図２（ａ）は入水前の断水状態であり、濾材ユニット２０を収容した本体容器１０を装着する前の流水経路の状態である。図２（ｂ）は本体容器１０を新しく装着して、あるいは、しばらく使用していなかった後での再使用時の濾材ユニット２０の洗浄中での流水経路の状態である。図２（ｃ）は浄水作業を連続して行っている状態での流水経路の状態である。 Hereinafter, the flow path of each mode will be described along FIG.
FIG. 2A shows a water cut-off state before entering water, and is a state of a flowing water path before mounting the
図２（ａ）では、第１の通水路３６が原水の入水接続口３２に接続されていないので、本体容器１０に水が供給されていない状態、即ち、断水状態にある。
In FIG. 2A, since the first water passage 36 is not connected to the raw water inlet connection port 32, water is not supplied to the main body container 10, that is, it is in a water cutoff state.
図２（ａ）から、インナーヘッド３５を右回りに回転させ、第１の通水路３６を原水の入水接続口３２につなげ、第２の通水路３７のうち一方の通水路を洗浄水排出口３４につなげると図２（ｂ）となって洗浄モードになる。このモードは、長時間使用していないときや本体容器１０の内部に溜まったサビ等による目詰まりを解消させるとき等に使用するものである。
From FIG. 2A, the inner head 35 is rotated clockwise, the first water passage 36 is connected to the raw water inlet connection port 32, and one of the second water passages 37 is connected to the washing water discharge port. When connected to 34, the cleaning mode is set as shown in FIG. This mode is used when not used for a long time or when clogging due to rust or the like accumulated inside the main body container 10 is eliminated.
このモードでは、原水が入水接続口３２から第１の通水路３６に入り、入水口１４から本体容器１０内に原水が供給される。供給された水は、濾材ユニット２０を通って出水口１５から第２の通水路３７に流出されるが、第２の通水路３７のうち一方の通水路はヘッド本体３１によって出口が塞がれているため外部に流出できないが、もう一方の通水路が洗浄水排出口３４につながっているため、洗浄水排出口３４を通って外部に流出する。これにより、濾材ユニット２０が洗浄される。この洗浄モードでは原水の通水速度を通常の浄水時の通水速度よりも速くして洗浄効果を向上することができる。
In this mode, raw water enters the first water passage 36 from the water inlet port 32, and raw water is supplied into the main body container 10 from the water inlet 14. The supplied water flows out from the water outlet 15 to the second water passage 37 through the filter medium unit 20, but the outlet of one of the second water passages 37 is blocked by the head body 31. However, since the other water passage is connected to the washing water discharge port 34, it flows out to the outside through the washing water discharge port 34. Thereby, the filter medium unit 20 is washed. In this cleaning mode, the flow rate of the raw water can be made faster than the flow rate during normal water purification to improve the cleaning effect.
図２（ｂ）から、インナーヘッド３５をさらに右回りに回転させ、第１の通水路３６を原水の入水接続口３２につなげ、第２の通水路３７の一方を浄水の出水接続口３３につなげると図２（ｃ）となって浄水作業モードになる。
From FIG. 2 (b), the inner head 35 is further rotated clockwise, the first water passage 36 is connected to the raw water inlet connection port 32, and one of the second water passages 37 is connected to the purified water outlet / outlet port 33. If it connects, it will become FIG.2 (c) and will be in the water purification work mode.
この状態では、原水が入水接続口３２から第１の通水路３６に入り、入水口１４から本体容器１０内に原水が供給される。供給された水は、濾材ユニット２０を通って出水口１５から第２の通水路３７に流出される。第２の通水路３７のうち一方の通水路はヘッド本体３１によって出口が塞がれているため外部に流出できないが、もう一方の通水路が出水接続口３３につながっているため、濾材ユニット２０を経由した浄水が出水接続口３３を通って外部に供給される。
In this state, the raw water enters the first water passage 36 from the water inlet port 32, and the raw water is supplied into the main body container 10 from the water inlet 14. The supplied water flows out from the water outlet 15 to the second water passage 37 through the filter medium unit 20. One of the second water passages 37 cannot flow out to the outside because the outlet is blocked by the head body 31, but the other water passage is connected to the water outlet connection port 33, so the filter medium unit 20. The purified water passing through is supplied to the outside through the water outlet port 33.
以上に述べたように、本発明の浄水器によると、第１～第３の濾材からなる濾材ユニットを、１つの円筒状の本体容器に収納・配置したため、一定の水質基準を満たし、総重量が軽く、浄水が必要な場所に携帯して使用することが容易となる。また、逆浸透膜フィルターを用いないため、比較的低コストで製造することができ、また、単位時間での浄水量も十分確保することが出来る。
As described above, according to the water purifier of the present invention, the filter medium unit composed of the first to third filter media is housed and arranged in one cylindrical main body container. Is light and easy to carry and use in places where clean water is needed. Moreover, since a reverse osmosis membrane filter is not used, it can be manufactured at a relatively low cost, and a sufficient amount of purified water per unit time can be secured.
更に、濾材が目詰まりを起こした場合に、濾材の表面に、通常の浄水時の流水速度よりも速い洗浄水を流して、この洗浄水によって濾材の表面の汚れを洗い流し、これによって濾材の寿命を保つようにし、通常の浄水供給作業と、洗浄作業と、断水状態との切り替えが簡単、容易に行うことが出来る。
In addition, when the filter medium is clogged, wash water that is faster than the normal water flow rate to the surface of the filter medium to wash away dirt on the surface of the filter medium. Therefore, it is possible to easily and easily switch between normal clean water supply work, cleaning work, and water outage.
なお、本体容器の内部流水路内にカートリッジ化したプレフィルターを設けて比較的大きなごみなどを予め除去するようにしてもよい。
It should be noted that a pre-filter formed as a cartridge may be provided in the internal flow channel of the main body container to remove relatively large dust in advance.
