Description

本発明は、水道水を浄化する浄水器に関し、さらに詳しくは、キッチン下のキャビネットが前後方向にスライドする、引き出し奥側の板に設置するアンダーシンク型浄水器に関する。 TECHNICAL FIELD The present invention relates to a water purifier for purifying tap water, and more particularly to an undersink type water purifier installed on a plate on the back side of a drawer where a cabinet under a kitchen slides in the front-rear direction.

従来、水道水を浄化する浄水器としては、水道水栓の吐出口に直結する蛇口直結型浄水器、キッチンの上に置いて使用する据置型浄水器、キッチンの内部に置いて使用するアンダーシンク型（またはビルトイン型）浄水器などが知られている。いずれも浄水器用フィルタカートリッジに充填した濾材は処理できる総濾過水量が限られているため、使用者は、浄水器用フィルタカートリッジを定期的に交換しながら浄水器を継続使用する。 Conventionally, as a water purifier for purifying tap water, a faucet direct connection type water purifier that is directly connected to the outlet of the tap water faucet, a stationary water purifier used on the kitchen, and an undersink used inside the kitchen Type (or built-in type) water purifiers are known. In both cases, the total amount of filtered water that can be treated by the filter medium filled in the water purifier filter cartridge is limited, so that the user continues to use the water purifier while regularly exchanging the water purifier filter cartridge.

アンダーシンク型浄水器は、蛇口直結型浄水器や据置型浄水器に比べて大型であり、処理できる総濾過水量も大きいため長期間使用できる。キッチンの水栓やシンク近傍に浄水器を置かないので、作業の邪魔にならない。 The undersink type water purifier is larger than the faucet direct connection type water purifier and the stationary type water purifier, and the total amount of filtered water that can be processed is large, so it can be used for a long time. There is no water purifier near the kitchen faucet or sink, so it does not interfere with work.

アンダーシンク型浄水器としては、例えば特許文献１のように、原水入口と浄水出口を備え、ワンタッチジョイントを先端に取り付けたホースを接続して使用するものが知られている。使用者は、浄水器用カートリッジをシンク下の空間の底面に置き、原水供給用のホースと、浄水吐出用のホースを接続する。キッチンの水栓を操作すれば容易に浄水を得ることができる。 As an under-sink type water purifier, for example, as disclosed in Patent Document 1, one having a raw water inlet and a water purifying outlet and using a hose having a one-touch joint attached to its tip is used. The user places the water purifier cartridge on the bottom surface of the space under the sink and connects the hose for supplying raw water and the hose for discharging purified water. You can easily obtain purified water by operating the kitchen faucet.

しかし、このタイプの浄水器は、通常、流し台収納部の奥に設置されており、キッチン下のキャビネットが前後方向にスライド可能な引き出しタイプであると、浄水器を取り出すには手前に収められている物品を取り出さなければならず、交換に手間がかかるという問題があった。 However, this type of water purifier is usually installed in the back of the sink storage part, and if the cabinet under the kitchen is a drawer type that can slide in the front-back direction, it will be stored in front of you to take out the water purifier. There is a problem that it is necessary to take out the existing article and it takes time to replace it.

これに対し、例えば特許文献２のように、浄水器用カートリッジのジョイントを保護することができ、さらに浄水器用カートリッジの交換が容易であるカートリッジホルダーと、これを備えるカートリッジ装置が知られている。使用者は、キッチン下のキャビネットの引き出しを使用者の手前側に引き出すことで、カートリッジホルダーから浄水器用カートリッジを容易に取り出すことができ、交換に手間がかからない。 On the other hand, there is known a cartridge holder that can protect the joint of the water purifier cartridge and that allows easy replacement of the water purifier cartridge, and a cartridge device including the same, as disclosed in Patent Document 2, for example. The user can easily take out the water purifier cartridge from the cartridge holder by pulling out the drawer of the cabinet under the kitchen to the front side of the user, and it does not take time and effort for replacement.

特開２００７−２７５８１４号公報JP, 2007-275814, A 国際公開第２０１５／１９９１４５号International Publication No. 2015/199145

しかしながら、特許文献２に提案されているカートリッジ装置は、浄水器用カートリッジがキッチンの流し台に設置された浄水器用水栓に配管及びホースを介して接続されており、キッチン下のキャビネットが前後方向にスライドすることに伴いホースも動き、ホースが動く際に発生するねじれにより、浄水器用水栓とホースとの接続部位から水漏れが起こるおそれがある。 However, in the cartridge device proposed in Patent Document 2, the cartridge for the water purifier is connected to the water faucet for the water purifier installed on the sink of the kitchen through the pipe and the hose, and the cabinet under the kitchen slides in the front-rear direction. As a result, the hose also moves, and twisting that occurs when the hose moves may cause water leakage from the connection portion between the water purifier faucet and the hose.

そこで、本発明は、従来の技術における上記の問題点に鑑み、浄水器用水栓とホースとの接続部位を回動可能にすることで、キャビネットが前後方向にスライドすることにより発生するホースのねじれを逃がして、浄水器用水栓とホースとの接続部位からの水漏れを防ぐことができる浄水器を提供する。 Therefore, in view of the above problems in the prior art, the present invention makes the connection part between the faucet for the water purifier and the hose rotatable, so that the twist of the hose caused by the cabinet sliding in the front-back direction. Provided is a water purifier capable of preventing water leakage from a connection portion between a water faucet faucet and a hose.

And the connection part 104 for connecting with the faucet 3 is attached to the other end of the raw water introduction pipe 7 and the other end of the purified water discharge pipe 8, respectively.

次に、接続部１０４を構成する各部材について説明する。
図２に示すように、接続部１０４は、口金具１１、継手本体１００、抜け止め部材１０１、Оリング１０３、締結部材１５およびホース体１６から構成されている。 Next, each member which comprises the connection part 104 is demonstrated.
As shown in FIG. 2, the connecting portion 104 includes a fitting 11, a joint body 100, a retaining member 101, an O-ring 103, a fastening member 15, and a hose body 16.

口金具１１は、円筒状の頭部１４とこの頭部１４から延びる円筒状のニップル部（ホース接続部）１３とで構成され、中心部に頭部１４とニップル部１３とを貫通する流路が形成されている。頭部１４の外径はニップル部１３の外径よりも大きくなっており、口金具１４は全体として外径に段差のある円筒体になっている。 The mouth metal fitting 11 includes a cylindrical head 14 and a cylindrical nipple portion (hose connection portion) 13 extending from the head portion 14, and a flow passage penetrating the head portion 14 and the nipple portion 13 in a central portion. Are formed. The outer diameter of the head portion 14 is larger than the outer diameter of the nipple portion 13, and the fitting 14 is a cylindrical body having a stepped outer diameter as a whole.

ホース体１６はニップル部１３に挿入され、ホース体１６の外周に取り付けた締結部材１５を圧迫して固定することにより、ホース体１６はニップル部１３と締結部材１５の間に固定される。 The hose body 16 is inserted into the nipple portion 13 and the fastening member 15 attached to the outer periphery of the hose body 16 is pressed and fixed, whereby the hose body 16 is fixed between the nipple portion 13 and the fastening member 15.

ホース体１６を圧迫して固定する締結部材１５は、配管用ホースを接続して通水した際に、水が漏れたり、水圧によってホースが抜けないものであればよい。このような締結部材としては、加締めて固定する加締め用スリーブ、ホースクランプ、結束バンドなどがある。 The fastening member 15 that presses and fixes the hose body 16 may be any member that does not leak water or the hose cannot be removed by water pressure when a hose for piping is connected and water is passed. Examples of such a fastening member include a swaging sleeve that is swaged and fixed, a hose clamp, and a binding band.

締結部材１５の材料は、ポリプロピレン、ポリアセタール、ポリエチレン、ナイロン、ポリカーボネートなどの安価な樹脂でもよいが、強度の観点から、ステンレス、黄銅、青銅などの金属が好ましい。 The material of the fastening member 15 may be an inexpensive resin such as polypropylene, polyacetal, polyethylene, nylon or polycarbonate, but from the viewpoint of strength, metals such as stainless steel, brass and bronze are preferable.

図２で図示している口金具１１とホース体１６との接続方式は、ホース体１６の内側にニップル部１３を挿入する方式であるが、例えばワンタッチ継手のように、ホース体１６の外側をシールする方式を採用してもよい。 The connection method between the fitting 11 and the hose body 16 shown in FIG. 2 is a method in which the nipple portion 13 is inserted inside the hose body 16. A sealing method may be adopted.

継手本体１００には円形の凹部である挿入凹部２２０がある。挿入凹部２２０の底面には外部に通ずる開口が開けられており、側壁２４９には全周に渡る環状溝１０２が形成されている。 The joint body 100 has an insertion recess 220 which is a circular recess. An opening that communicates with the outside is opened in the bottom surface of the insertion recess 220, and the sidewall 249 is formed with an annular groove 102 that extends over the entire circumference.

口金具１１および継手本体１００は、強度の観点から、ステンレス、黄銅、青銅などの金属で製造するのが好ましい。 From the standpoint of strength, the fitting 11 and the joint body 100 are preferably made of a metal such as stainless steel, brass, or bronze.

図２、３に図示されているように、抜け止め部材１０１は全体が板状体であり、内側が開口部１７になっている。開口部１７の大きさは、口金具１１のニップル部１３は通るが頭部１４は通らない大きさになっている。さらに、抜け止め部材１０１の外縁２５０の最外径は、口金具１１の頭部１４の外径よりも大きくなっている。 As shown in FIGS. 2 and 3, the retaining member 101 is a plate-shaped member as a whole, and has an opening 17 inside. The size of the opening portion 17 is such that the nipple portion 13 of the mouth fitting 11 can pass through but the head portion 14 cannot pass through. Furthermore, the outermost diameter of the outer edge 250 of the retaining member 101 is larger than the outer diameter of the head 14 of the mouthpiece 11.

抜け止め部材１０１をニップル部１３にはめた口金具１１が、継手本体１００の挿入凹部２２０に挿入され、口金具１１が挿入された状態で、抜け止め部材１０１の外縁２５０が継手本体１００の環状溝１０２にはめられている。抜け止め部材１０１は、口金具１１の頭部１４の頭部端面２２３を押さえた状態で環状溝１０２に固定されているので、抜け止め防止部材１０１は、継手本体１００の挿入凹部２２０に口金具１１を軸方向に固定し、口金具１１の脱落を防止していることと併せて、口金具１１の回動を可能にしている。 The fitting 11 having the retaining member 101 fitted in the nipple portion 13 is inserted into the insertion recess 220 of the joint body 100, and the outer edge 250 of the retaining member 101 is formed into an annular shape of the joint body 100 with the fitting 11 inserted. It is fitted in the groove 102. The retaining member 101 is fixed to the annular groove 102 while pressing the head end surface 223 of the head 14 of the fitting 11, so that the retaining member 101 fits into the insertion recess 220 of the joint body 100. 11 is fixed in the axial direction to prevent the mouth metal fitting 11 from falling off, and at the same time, the mouth metal fitting 11 can be rotated.

また、口金具１１の頭部１４の外周面にはＯリング１０３が配置されており、このＯリング１０３が継手本体１００の挿入凹部２２０の内周面に接することにより、口金具１１と継手本体１００とは液密に結合され、口金具１１と継手本体１００との間の液密性が確保されている。 Further, an O-ring 103 is arranged on the outer peripheral surface of the head 14 of the mouth fitting 11, and the O-ring 103 contacts the inner peripheral surface of the insertion recess 220 of the joint body 100, whereby the mouth fitting 11 and the joint body are It is liquid-tightly coupled to 100, and the liquid-tightness between the fitting 11 and the joint body 100 is secured.

原水導入管７を流れる原水と浄水導出管８を流れる浄水は、それぞれ、口金具１１の頭部１４とニップル部１３とを貫通する流路、および継手本体１００の挿入凹部２２０の底面に開けられた開口を通って、接続部１０４の内部を流れる。 The raw water flowing through the raw water introducing pipe 7 and the purified water flowing through the purified water outlet pipe 8 are opened in the flow passages that pass through the head 14 of the mouthpiece 11 and the nipple portion 13 and the bottom of the insertion recess 220 of the joint body 100, respectively. Through the opened opening and flows inside the connection portion 104.

継手本体１００の内部の側壁２４９から環状溝１０２の外径までの長さ、いわゆる環状溝１０２の溝深さは、抜け止め防止部材１０１の耐圧性の確保のためには大きいほうが有利である。一方で、環状溝１０２の溝深さを大きくすると当然ながら継手本体１００のサイズが大きくなりコストが上がる。そのため、耐圧性とコストの兼ね合いを考慮し、環状溝１０２の溝深さは０．４〜２．０ｍｍが好ましい。 It is advantageous that the length from the side wall 249 inside the joint body 100 to the outer diameter of the annular groove 102, that is, the groove depth of the annular groove 102, is large in order to secure the pressure resistance of the retaining member 101. On the other hand, if the groove depth of the annular groove 102 is increased, the size of the joint body 100 is naturally increased and the cost is increased. Therefore, in consideration of the balance between pressure resistance and cost, the groove depth of the annular groove 102 is preferably 0.4 to 2.0 mm.

抜け止め部材１１の開口部１７は、口金具１１の頭部１４以外の部分が通り、かつ頭部１４の頭部端面２２３を押さえる形状であればよいので、円形状、角形状、長円状形状、Ｕ字形状などの様々な形状で形成できる。これらの中でも、頭部端面２２３と同じ円形状であれば、開口部の大きさを最小にして頭部端面２２３との接触面積を確保できるため、強度の観点から好ましい
図３に開示されている抜け止め部材１０１は、隣接する部材を固定するリング状の穴用Ｃ形止め輪であるが、これには限定されない。 The opening 17 of the retaining member 11 may have any shape as long as it passes through a portion other than the head 14 of the mouthpiece 11 and presses the head end surface 223 of the head 14. It can be formed in various shapes such as a shape and a U shape. Among these, if the shape is the same as the head end surface 223, the size of the opening can be minimized and the contact area with the head end surface 223 can be secured, which is preferable from the viewpoint of strength. The retaining member 101 is a ring-shaped C-shaped retaining ring for fixing adjacent members, but is not limited to this.

抜け止め部材１０１は、ＡＢＳ樹脂、ポリカーボネート、ポリスチレン、ポリプロピレンなどの樹脂でもよいが、強度の観点から、ステンレス、黄銅、青銅などの金属で製造するのが好ましい。 The retaining member 101 may be made of a resin such as ABS resin, polycarbonate, polystyrene, or polypropylene, but is preferably made of a metal such as stainless steel, brass, or bronze from the viewpoint of strength.

抜け止め部材１０１の板厚は、耐圧性の確保のため大きいほうが有利であるが、板厚を大きくすると当然ながらコストが上がるため、耐圧性とコストの兼ね合いを考慮し、板厚は０．３〜３．０ｍｍが好ましい。 It is advantageous that the plate thickness of the retaining member 101 is large in order to secure pressure resistance. However, since increasing the plate thickness naturally raises cost, the plate thickness is 0.3 in consideration of the balance between pressure resistance and cost. It is preferably 3.0 mm.

上記の構造により、原水導入管７と浄水導出管８を回転可能にすることができる。これより、浄水器用水栓３と原水導入管７、浄水器用水栓３と浄水導出管８を接続する際に発生するねじれを逃がして、浄水器用水栓３との接続部位からの水漏れを防ぐことができる。 With the above structure, the raw water introduction pipe 7 and the purified water discharge pipe 8 can be made rotatable. From this, the twist generated when connecting the water purifier faucet 3 and the raw water introduction pipe 7, and the water purifier faucet 3 and the purified water discharge pipe 8 is released, and water leakage from the connection part with the water purifier faucet 3 is prevented. Can be prevented.

また、継手本体１００と抜け止め部材１０１は環状溝１０２により強固に固定されるため、浄水器１に高い水圧がかかった場合でも水漏れを防ぐことができる。また、抜け止め部材１０１はプライヤーなどの工具を用いない限り取り外すことができないため、使用者が誤って分解することを防止できる。 Further, since the joint body 100 and the retaining member 101 are firmly fixed by the annular groove 102, water leakage can be prevented even when a high water pressure is applied to the water purifier 1. Further, since the retaining member 101 cannot be removed unless a tool such as pliers is used, it is possible to prevent the user from accidentally disassembling.

次に浄水器１の設置について説明する。本発明の浄水器１の設置場所は、浄水器１がキッチン５の流し台に設置された浄水器用水栓３に原水導入管７および浄水導出管８を介して接続されたものであり、キッチン５下のキャビネット４が前後方向にスライドすることに伴い原水導入管７および浄水導出管８も動く、キッチン５下のキャビネット４に設置して使用するアンダーシンク型浄水器として用いれば、従来の課題を解決できて有効である。 Next, the installation of the water purifier 1 will be described. The location of the water purifier 1 of the present invention is such that the water purifier 1 is connected to the faucet 3 for a water purifier installed in the sink of the kitchen 5 via the raw water introduction pipe 7 and the purified water discharge pipe 8. The raw water inlet pipe 7 and the purified water outlet pipe 8 move as the lower cabinet 4 slides in the front-rear direction. If used as an undersink type water purifier installed and used in the cabinet 4 below the kitchen 5, the conventional problems can be solved. It can be solved and is effective.

浄水器１の原水導入管７と、浄水導出管８は、キッチン５の浄水器用水栓３に接続されている。浄水器用水栓３のレバーを回すなどして開栓すると、浄水器用水栓３に内蔵された弁機構から原水導入管７に水道水が供給されるようになっている。浄水器１で浄化された浄水が浄水導出管８から浄水器用水栓３に戻り、弁機構を通過せずに浄水器用水栓３の吐出口からそのまま吐出される。すなわち浄水器用水栓３に内蔵された弁機構より下流側に浄水器１が設けられ、止水時には浄水器１に水圧がかからないようになっている。いわゆるＩＩ形の浄水器である。しかしながら本発明の浄水器１はＩＩ形に限定されない。止水時に浄水器１に水圧がかかる、いわゆるＩ形の浄水器として使用してもよい。 The raw water introduction pipe 7 and the purified water discharge pipe 8 of the water purifier 1 are connected to the water purifier faucet 3 of the kitchen 5. When the tap of the water purifier faucet 3 is opened by turning the lever or the like, tap water is supplied to the raw water introduction pipe 7 from the valve mechanism built in the water purifier faucet 3. The purified water purified by the water purifier 1 returns from the purified water outlet pipe 8 to the water purifier faucet 3 and is discharged from the outlet of the water purifier faucet 3 without passing through the valve mechanism. That is, the water purifier 1 is provided on the downstream side of the valve mechanism incorporated in the water purifier faucet 3 so that no water pressure is applied to the water purifier 1 when water is stopped. This is a so-called type II water purifier. However, the water purifier 1 of the present invention is not limited to the II type. It may be used as a so-called I-type water purifier in which water pressure is applied to the water purifier 1 when water is stopped.
