Description

本発明は、原水を流下させる際に浄化させる浄水カートリッジを備えた浄水器に関する。 The present invention relates to a water purifier equipped with a water purification cartridge for purifying when to flow down the raw water.

従来から、浄水カートリッジを備えた浄水器として、いわゆるポット型のものが知られている。このポット型の浄水器は、上側に位置する原水貯留部と、下側に位置する浄水貯留部との間に浄水カートリッジを介在させ、原水貯留部側に貯留される原水が自重により浄水カートリッジを通じて浄水貯留部側にまで流下する際に、浄水カートリッジ内にて原水を浄化する構造になっている。   Conventionally, what is called a pot type is known as a water purifier provided with a water purification cartridge. This pot-type water purifier has a water purification cartridge interposed between a raw water storage part located on the upper side and a purified water storage part located on the lower side, and the raw water stored on the raw water storage part side passes through the water purification cartridge by its own weight. When flowing down to the purified water storage unit side, the raw water is purified in the purified water cartridge.

図６には、上記構造の浄水カートリッジ１を具備する浄水器５０として、特許文献１に記載のものを示している。この浄水カートリッジ１は、充填してある吸着剤（活性炭）の吸着作用によって原水を浄化する上流側の吸着浄水部２と、充填してある濾過体（中空糸膜）の濾過作用によって吸着浄水部２を通過した原水を更に浄化する下流側の濾過浄水部３とを具備したものである。このように、吸着浄水部２の下流側に濾過浄水部３を配することで、下流側の濾過浄水部３によって細菌や微生物を濾過除去した後、速やかに浄水貯留部５２内に吐出することができて衛生的であるという利点がある。図中の符号５１は原水貯留部である。   In FIG. 6, the thing of patent document 1 is shown as the water purifier 50 which comprises the water purification cartridge 1 of the said structure. The water purification cartridge 1 includes an adsorption water purification unit 2 on the upstream side that purifies raw water by the adsorption action of the filled adsorbent (activated carbon), and an adsorption water purification part by the filtration action of the filled filter body (hollow fiber membrane). 2 and a downstream filtered water purification unit 3 that further purifies the raw water that has passed through 2. In this way, by disposing the filtered water purification unit 3 on the downstream side of the adsorption water purification unit 2, bacteria and microorganisms are filtered and removed by the downstream filtration water purification unit 3, and then immediately discharged into the purified water storage unit 52. Has the advantage of being hygienic and hygienic. The code | symbol 51 in a figure is a raw | natural water storage part.

ところで、特許文献１に開示される上記の浄水カートリッジ１にあっては、吸着浄水部２とこれの下方に位置する濾過浄水部３とを仕切りなく上下に連通させ、吸着浄水部２側に生じた気泡と濾過浄水部３側に生じた気泡とを共に、浄水カートリッジ１の頂部中央に設けた排気口７０から外部に排出させる構造になっている。このため、濾過浄水部３側に生じた気泡が上方の吸着浄水部２内を通過する際に、気泡の一部が吸着浄水部２内の吸着剤に付着して残留し、結果的に通水性能の低下や浄水の水質の不安定化を招くという問題がある。   By the way, in said water purification cartridge 1 disclosed by patent document 1, the adsorption water purification part 2 and the filtration water purification part 3 located under this are connected up and down without partitioning, and it arises at the adsorption water purification part 2 side. Both the air bubbles and the air bubbles generated on the filtered water purification unit 3 side are discharged from the exhaust port 70 provided at the center of the top of the water purification cartridge 1 to the outside. For this reason, when bubbles generated on the filtered water purification unit 3 pass through the upper adsorption water purification unit 2, some of the bubbles remain attached to the adsorbent in the adsorption water purification unit 2. There is a problem that water performance deteriorates and water quality becomes unstable.

また、浄水カートリッジ１内全体に原水が充填された状態において、吸着浄水部２内の吸着剤が上方に浮上して頂部の排気口７０を目詰まりさせる虞があり、この場合には浄水カートリッジ１内全体の空気抜きが上手くできず、結果的に通水性能の低下や浄水の水質の不安定化を招くという問題がある。
特開２００４−２３０３３５号公報 Further, in a state where the whole of the water purification cartridge 1 is filled with raw water, the adsorbent in the adsorption water purification unit 2 may float upward and clog the top exhaust port 70. In this case, the water purification cartridge 1 There is a problem that the air inside cannot be vented well, resulting in deterioration of water flow performance and instability of purified water.

A cartridge housing 30 that forms the outer shell of the water purification cartridge 1 is formed by the upper cover 16 and the adsorption container 7.

上カバー１６の周壁であってミネラル容器１５の側方に位置する部分には、小径の導水口１７を全周に亘って多数開口させており、これら導水口１７を通じて浄水カートリッジ１内に原水が導入される構造である。また、上カバー１６の頂部であって濾過容器６内の濾過浄水部３の真上に位置する部分には、濾過部側排気口１８を上下方向に貫通形成している。ミネラル容器１５の上方に経込んだ凹段部１５ａの底面中央部からは、ミネラル容器１５のミネラル剤を収容する部分を抜けて上方に伸びる細長パイプ状の空気抜き路１９が延設されている。空気抜き路１９の上端開口は、上カバー１６の濾過部側排気口１８に連通接続させる。つまり、ミネラル容器１５の凹段部１５ａに接続される濾過容器６内の濾過浄水部３は、この空気抜き路１９及び濾過部側排気口１８を通じて上方の原水貯留部５１に連通接続される構造である。   A large number of small-diameter water inlets 17 are opened over the entire circumference of the peripheral wall of the upper cover 16 and located on the side of the mineral container 15, and the raw water enters the purified water cartridge 1 through these water inlets 17. The structure to be introduced. In addition, a filtration unit-side exhaust port 18 is formed through the top portion of the upper cover 16 and directly above the filtered water purification unit 3 in the filtration container 6 in the vertical direction. From the center of the bottom surface of the concave step portion 15a that passes above the mineral container 15, an elongated pipe-like air vent path 19 that extends upward through a portion of the mineral container 15 containing the mineral agent is extended. The upper end opening of the air vent channel 19 is connected to the filtration unit side exhaust port 18 of the upper cover 16 in communication. That is, the filtered water purification unit 3 in the filtration container 6 connected to the concave step portion 15a of the mineral container 15 is connected to the upper raw water storage unit 51 through the air vent channel 19 and the filtration unit side exhaust port 18. is there.

また、ミネラル容器１５の外周壁には、スリット状のミネラル溶出孔２０を多数穿設している。このミネラル溶出孔２０は、ミネラル容器１５内の空間であるミネラル添加部５と吸着容器７内の空間である吸着浄水部２とを連通接続させる流路を成すものである。更に、ミネラル容器１５の周壁の上端縁には、下方に凹設した切り欠き２１が周方向に間隔を空けて複数設けてあり、ミネラル容器１５の上端開口縁が上カバー１６の内面に密着したときに、各切り欠き２１が、下方のミネラル溶出孔２０とは別にミネラル添加部５と吸着浄水部２を連通させる空気導入孔２２を成すようにしている。ミネラル溶出孔２０や空気導入孔２２の幅は、充填されるミネラル剤の径よりも小さく設けている。   In addition, a large number of slit-like mineral elution holes 20 are formed in the outer peripheral wall of the mineral container 15. The mineral elution hole 20 forms a flow path that connects the mineral addition section 5 that is a space in the mineral container 15 and the adsorption water purification section 2 that is a space in the adsorption container 7. Further, a plurality of cutouts 21 recessed downward are provided at the upper end edge of the peripheral wall of the mineral container 15 at intervals in the circumferential direction, and the upper end opening edge of the mineral container 15 is in close contact with the inner surface of the upper cover 16. Sometimes, each notch 21 forms an air introduction hole 22 that communicates the mineral addition part 5 and the adsorbed water purification part 2 separately from the mineral elution hole 20 below. The widths of the mineral elution holes 20 and the air introduction holes 22 are set smaller than the diameter of the mineral agent to be filled.

ここで、上カバー１６の頂部であって濾過部側排気口１８を囲む部分には、周方向に等間隔を隔てて複数の排気口２３を濾過部側排気口１８とは別に上下方向に穿設している。この排気口２３は、ミネラル添加部５内に生じる気泡をカートリッジ外に排出させるものであり、且つ、吸着浄水部２内に生じる気泡をカートリッジ外に排出させる吸着部側排気口２４を兼用したものである。上カバー１６の頂部であって各排気口２３を囲む部分からは、排気口２３の周方向に等間隔を隔てて複数の突起部２５を内方に（即ち下方に）延設しており、ミネラル添加部５内に充填されるミネラル剤が各排気口２３に詰まることを防止している。   Here, at the top of the upper cover 16 and surrounding the filtration unit side exhaust port 18, a plurality of exhaust ports 23 are bored in the vertical direction separately from the filtration unit side exhaust port 18 at equal intervals in the circumferential direction. Has been established. The exhaust port 23 is used to discharge bubbles generated in the mineral addition unit 5 to the outside of the cartridge, and also serves as an adsorption unit side exhaust port 24 for discharging bubbles generated in the adsorption water purification unit 2 to the outside of the cartridge. It is. A plurality of projecting portions 25 extend inwardly (that is, downward) at equal intervals in the circumferential direction of the exhaust port 23 from the top portion of the upper cover 16 and surrounding each exhaust port 23. The mineral agent filled in the mineral addition part 5 is prevented from clogging each exhaust port 23.

ところで、上記構成の浄水カートリッジ１を浄水器５０に装着する際、浄水カードリッジ１の浄水部４が形成される下半部を、原水貯留部５１から下方に凹設される上記装着凹段部６２内に嵌め込み、浄水カートリッジ１のミネラル添加部５を形成する上半部を原水貯留部５１の最下部５１ａよりも上方に位置させるのであるが、このとき装着凹段部６２の底部中央の開口を通じて、吸着容器７の段部８の吐出口９や該段部８内に位置する濾過容器６の下端部が下方の浄水貯留部５２側に突出する。   By the way, when the water purification cartridge 1 having the above configuration is attached to the water purifier 50, the lower half of the water purification card ridge 1 where the water purification part 4 is formed is recessed downward from the raw water storage part 51. The upper half of the water purification cartridge 1 that forms the mineral addition portion 5 is positioned above the lowermost portion 51a of the raw water storage portion 51. At this time, the opening at the center of the bottom of the mounting concave step portion 62 is placed. Through, the discharge port 9 of the step portion 8 of the adsorption container 7 and the lower end portion of the filtration container 6 located in the step portion 8 protrude toward the lower purified water storage portion 52 side.

吸着容器７の周壁には、外側方に向けて凸状に形成される弾性変形可能な凸部２６が全周に亘って一体に形成されており、この凸部２６を全周に亘って装着凹段部６２の内周面に弾接させることで、吸着容器７の周壁と装着凹段部６２とを密着させている。また、吸着容器７の段部８の外周面の溝部にはＯリング２７を嵌め込んでおり、このＯリング２７を介して段部８と装着凹段部６２とを密着させている。   An elastically deformable convex portion 26 formed in a convex shape toward the outer side is integrally formed on the peripheral wall of the adsorption container 7 over the entire circumference, and the convex portion 26 is attached over the entire circumference. By making elastic contact with the inner peripheral surface of the concave step portion 62, the peripheral wall of the adsorption container 7 and the mounting concave step portion 62 are brought into close contact with each other. Further, an O-ring 27 is fitted into the groove on the outer peripheral surface of the step portion 8 of the adsorption container 7, and the step portion 8 and the mounting concave step portion 62 are brought into close contact with each other through the O-ring 27.

そして、上記構成から成る浄水カートリッジ１を備えた本例の浄水器５０を用いて浄水を得ようとする場合は、以下の手順による。即ち、まず上蓋部５６のフラップ５８を上方に回動させて給水口５７を開き、給水口５７を通じて水道水等の原水を原水貯留部５１内に供給する。供給された原水は原水貯留部５１内に一旦貯留されるとともに、上カバー１６の多数の導水口１７を通じて浄水カートリッジ１内に導入され、吸着浄水部２およびこれに連通する濾過浄水部３やミネラル添加部５内にまで原水が充填される。   And when it is going to obtain purified water using the water purifier 50 of this example provided with the water purification cartridge 1 which consists of the said structure, it is based on the following procedures. That is, first, the flap 58 of the upper lid part 56 is rotated upward to open the water supply port 57, and raw water such as tap water is supplied into the raw water storage unit 51 through the water supply port 57. The supplied raw water is temporarily stored in the raw water storage section 51 and is introduced into the water purification cartridge 1 through a large number of water inlets 17 of the upper cover 16, and the adsorption water purification section 2 and the filtered water purification section 3 and minerals communicating therewith. Raw water is filled up to the addition part 5.

ここで、原水が自重により浄水カートリッジ１内を通って浄水貯留部５２にまで流下していく主流路は、導水口１７から流下した後に吸着浄水部２内に一旦溜まって吸着剤の吸着作用により浄化された後に、吸着浄水部２の下端部と連通する連通孔１４を通って濾過浄水部３内に導入され、濾過浄水部３内に充填される濾過体の濾過作用により更に濁り成分を濾過して浄化された後に、浄水カートリッジ１の最下端に開口される吐出口９を通じて下方の浄水貯留部５２内に順次流下していく流路である。この主流路を通過する過程で、吸着作用及び濾過作用による浄水が行われる。   Here, the main flow path in which the raw water flows down to the purified water storage section 52 through the purified water cartridge 1 by its own weight is temporarily accumulated in the adsorbed water purification section 2 after flowing down from the water inlet 17, due to the adsorption action of the adsorbent. After purification, the turbidity component is further filtered by the filtering action of the filter body introduced into the filtered water purification unit 3 through the communication hole 14 communicating with the lower end of the adsorption water purification unit 2 and filled in the filtered water purification unit 3. Then, after being purified, the flow path sequentially flows into the purified water storage section 52 below through the discharge port 9 opened at the lowermost end of the purified water cartridge 1. In the process of passing through the main flow path, water purification by adsorption and filtration is performed.

そして、この主流路に対してミネラル添加部５からは、該ミネラル添加部５内に充填された原水にミネラル剤のミネラル成分が溶出して得られた高ミネラル水が、ミネラル溶出孔２０を通じて順次供給されていく。つまり、浄水カートリッジ１内を通過する原水には、吸着作用及び濾過作用による浄水が行われるとともに、ミネラル成分が添加されるものである。   Then, from the mineral addition unit 5 to the main channel, high mineral water obtained by eluting the mineral component of the mineral agent into the raw water filled in the mineral addition unit 5 is sequentially supplied through the mineral elution hole 20. It will be supplied. That is, the raw water passing through the water purification cartridge 1 is subjected to water purification by an adsorption action and a filtration action, and a mineral component is added thereto.

ところで、浄水カートリッジ１内全体に原水が充填されて浄水が行われる際に、吸着浄水部２内や濾過浄水部３内に気泡が滞留していると通水性能が低下するとともに浄水の水質も不安定化する。しかし、上記構成の浄水カートリッジ１によれば、吸着浄水部２内に生じる気泡はミネラル溶出孔２０や空気導入孔２２を通じて上方のミネラル添加部５内にまで浮上したうえで、ミネラル添加部５内に生じる気泡と共に排気口２３から原水貯留部５１側に排出される。また、濾過浄水部３内に生じる気泡は濾過容器６内の上方にまで浮上したうえで、該濾過容器６と連通接続される空気抜き路１９を通じて濾過部側排気口１８に運ばれ、原水貯留部５１側に排出される。   By the way, when raw water is filled in the entire water purification cartridge 1 and water purification is performed, if bubbles remain in the adsorption water purification unit 2 or the filtration water purification unit 3, the water flow performance deteriorates and the water quality of the water is also improved. It becomes unstable. However, according to the water purification cartridge 1 configured as described above, bubbles generated in the adsorption water purification unit 2 float up to the upper mineral addition unit 5 through the mineral elution hole 20 and the air introduction hole 22, and then the inside of the mineral addition unit 5. Are discharged from the exhaust port 23 toward the raw water storage section 51 together with the bubbles generated in the water. Further, bubbles generated in the filtered water purification unit 3 float up to the upper side in the filtration container 6, and then are carried to the filtration unit side exhaust port 18 through the air vent path 19 connected to the filtration container 6, so that the raw water storage unit It is discharged to the 51 side.

なお、原水貯留部５１内において浄水カートリッジ１の濾過部側排気口１８よりも上方にまで原水が貯留されている場合であっても、この空気抜き路１９の上端部には空気溜りが常時生じて原水の流入を阻止する。したがって、空気抜き路１９を通じて原水貯留部５１内の原水が直接濾過浄水部３内に流入することは防止される。   Even when the raw water is stored in the raw water storage unit 51 above the filtration unit side exhaust port 18 of the water purification cartridge 1, an air pool is constantly generated at the upper end of the air vent path 19. Block inflow of raw water. Therefore, the raw water in the raw water storage unit 51 is prevented from flowing directly into the filtered water purification unit 3 through the air vent channel 19.

上記のように、本例の浄水カートリッジ１を備えた浄水器５０にあっては、浄水カートリッジ１内の水平方向中央部に位置する濾過浄水部３の上部から細長パイプ状の空気抜き路１９を上方に向けて延設し、濾過浄水部３内に生じる気泡を、該濾過浄水部３を水平方向に囲んで位置する吸着浄水部２を避けたうえで頂部の濾過部側排気口１８からカートリッジ外に排出する構造になっているので、濾過浄水部３内に生じた気泡の一部が吸着浄水部２内の吸着剤に付着して残留することがない。このため、気泡が残留することによる通水性能の低下や、浄水の水質の不安定化が防止されるものである。   As described above, in the water purifier 50 including the water purification cartridge 1 of the present example, the elongated pipe-like air vent path 19 extends upward from the upper part of the filtered water purification unit 3 located in the horizontal central portion in the water purification cartridge 1. The air bubbles generated in the filtered water purification unit 3 are directed to the outside of the cartridge from the top filtration unit side exhaust port 18 while avoiding the adsorbed water purification unit 2 positioned so as to surround the filtered water purification unit 3 in the horizontal direction. Therefore, a part of bubbles generated in the filtered water purification unit 3 does not remain attached to the adsorbent in the adsorption water purification unit 2. For this reason, the deterioration of the water flow performance and the destabilization of the quality of the purified water due to the remaining bubbles are prevented.

加えて、本例の浄水カートリッジ１では、浄水カートリッジ１の外殻を成すカートリッジハウジング３０の頂部（つまり上カバー１６の頂部）に、吸着浄水部２内の気泡を排出させる吸着部側排気口２４と、濾過浄水部３内の気泡を排出させる濾過部側排気口１８とを別々に設け、この濾過部側排気口１８内に上記空気抜き路１９の上端部を嵌合させて連通接続させている。したがって、原水が充填された状態の浄水カートリッジ１内において、吸着浄水部２内の吸着剤やミネラル添加部５内のミネラル剤が上方に浮上してきても、これらが空気抜き路１９や濾過部側排気口１８に詰まって空気抜き性能を低下させることは防止される。   In addition, in the water purification cartridge 1 of this example, the adsorption part side exhaust port 24 that discharges the bubbles in the adsorption water purification part 2 to the top part of the cartridge housing 30 that forms the outer shell of the water purification cartridge 1 (that is, the top part of the upper cover 16). And a filtration unit side exhaust port 18 for discharging bubbles in the filtered water purification unit 3 are separately provided, and the upper end portion of the air vent path 19 is fitted into the filtration unit side exhaust port 18 to be connected in communication. . Therefore, even if the adsorbent in the adsorption water purification unit 2 or the mineral agent in the mineral addition unit 5 rises upward in the water purification cartridge 1 filled with raw water, they are exhausted from the air vent 19 or the filtration unit side. The clogging of the mouth 18 is prevented from deteriorating the air venting performance.

図４には、本発明の実施形態における他例の浄水カートリッジ１を備えた浄水器５０を示している。本例の基本的な構成は上記した一例の構成と同様であるから、一例の構成と一致する構成については詳しい説明を省略し、一例とは相違する特徴的な構成についてのみ以下に詳述する。   In FIG. 4, the water purifier 50 provided with the water purification cartridge 1 of the other example in embodiment of this invention is shown. Since the basic configuration of this example is the same as the configuration of the example described above, detailed description of the configuration that matches the configuration of the example is omitted, and only the characteristic configuration that differs from the example is described in detail below. .

本例では、ミネラル容器１５の底面中央に設けた凹段部１５ａを、上方に向うにつれて水平方向の開口面積が小さくなるようにテーパ状に設けており、凹段部１５ａ中央の最も位置が高く且つ開口面積が小さな部分に、上方に向けて伸びる空気抜き路１９の下端を連通接続させている。このように、上側に経込んだ凹段部１５ａを、上側ほど開口面積が漸次小さくなっていって気泡を中央に集めるように設けることで、濾過浄水部３内に生じる気泡を集めて空気抜き路１９内に円滑に送り込んでいく空気捕集部４０を該濾過浄水部３の真上に形成している。   In this example, the concave step portion 15a provided at the center of the bottom surface of the mineral container 15 is provided in a tapered shape so that the opening area in the horizontal direction becomes smaller as it goes upward, and the center of the concave step portion 15a has the highest position. In addition, the lower end of the air vent path 19 extending upward is communicated with a portion having a small opening area. In this way, the concave step portion 15a that has passed through the upper side is provided so that the opening area gradually decreases toward the upper side and the bubbles are collected in the center, thereby collecting the bubbles generated in the filtered water purification unit 3 and removing the air. An air collecting part 40 that is smoothly fed into 19 is formed directly above the filtered water purification part 3.

また、本例では濾過部側排気口１８と連通する上側パイプ４１を上カバー１６から下方に延設し、凹段部１５ａ中央と連通する下側パイプ４２をミネラル容器１５から上方に延設し、上側パイプ４１と下側パイプ４２を連通接続させることで、空気抜き路１９を形成している。   In this example, the upper pipe 41 communicating with the filtration unit side exhaust port 18 extends downward from the upper cover 16, and the lower pipe 42 communicating with the center of the recessed step portion 15 a extends upward from the mineral container 15. The air vent path 19 is formed by connecting the upper pipe 41 and the lower pipe 42 in communication.

図５には、本発明の実施形態における更に他例の浄水カートリッジ１を備えた浄水器５０を示している。本例の基本的な構成は上記した他例の構成と同様であるから、他例の構成と一致する構成については詳しい説明を省略し、他例とは相違する特徴的な構成についてのみ以下に詳述する。   In FIG. 5, the water purifier 50 provided with the water purification cartridge 1 of the further another example in embodiment of this invention is shown. Since the basic configuration of this example is the same as the configuration of the other example described above, detailed description of the configuration that matches the configuration of the other example will be omitted, and only the characteristic configuration that is different from the other example will be described below. Detailed description.

本例では、上カバー１６の頂部に貫設する排気口４５によって、ミネラル添加部５内に生じる気泡をカートリッジ外に排出させる排気口２３と、吸着浄水部２内に生じる気泡をカートリッジ外に排出させる吸着部側排気口２４と、濾過浄水部３内に生じる気泡をカートリッジ外に排出させる濾過部側排気口１８とを兼用させている。つまり、一例や他例に比べて短く形成した空気抜き路１９を、濾過部側排気口１８を成す上方の排気口４５とは接続させずにミネラル添加部５内において上下に距離を隔てて位置させることで、空気抜き路１９の上端開口からミネラル添加部５の上部空間内に気泡を一旦吐出させたうえで、濾過部側排気口１８を成す排気口４５を通じてカートリッジ外に吐出させる構造になっている。   In this example, the exhaust port 45 penetrating the top of the upper cover 16 discharges air bubbles generated in the mineral addition unit 5 to the outside of the cartridge, and discharges air bubbles generated in the adsorption water purification unit 2 to the outside of the cartridge. The suction portion side exhaust port 24 to be used and the filtration portion side exhaust port 18 for discharging bubbles generated in the filtered water purification unit 3 to the outside of the cartridge are also used. That is, the air vent path 19 formed shorter than in the example and the other examples is not connected to the upper exhaust port 45 forming the filtration unit side exhaust port 18 and is positioned at a distance in the vertical direction in the mineral addition unit 5. Thus, after the air bubbles are once discharged from the upper end opening of the air vent path 19 into the upper space of the mineral addition unit 5, the air is discharged out of the cartridge through the exhaust port 45 forming the filtration unit side exhaust port 18. .
