In the embodiment of the present invention, the switch 2 is attached to the faucet in such a direction that the cartridge replacement time display means can be read. The left side facing away from the operator is referred to as the left side, and the surface farthest from the operator is referred to as the back side. In addition, the worker side is on the front side.
まず、本発明の実施形態の全体構成について説明する。
First, the overall configuration of the embodiment of the present invention will be described.
本発明の実施形態である浄水器1の外観正面図を図1に示す。浄水器1は、切替器2と切替器2に接続するろ過用のカートリッジ3と切替器2の下方を着脱可能に覆う保護カバー4で構成される。
FIG. 1 shows an external front view of a water purifier 1 according to an embodiment of the present invention. The water purifier 1 includes a switching device 2, a filtration cartridge 3 connected to the switching device 2, and a protective cover 4 that detachably covers the lower portion of the switching device 2.
切替器2は取付けナット11によって蛇口の先端に固定され、図2のように、切替弁12と、切替弁12を上下で挟んで覆い互いに係合する上カバー13と下カバー14と、切替弁12とつながり上カバー13および下カバー14の側方に位置する切替レバー15と、切替弁12の原水吐水部に接続される吐水キャップ17を有する。
The switching device 2 is fixed to the tip of the faucet by a mounting nut 11 and, as shown in FIG. 2, the switching valve 12, the upper cover 13 and the lower cover 14 that cover and engage with each other with the switching valve 12 interposed therebetween, and the switching valve 12, a switching lever 15 that is connected to the side of the upper cover 13 and the lower cover 14, and a water discharge cap 17 that is connected to the raw water discharge portion of the switching valve 12.
切替弁12は、蛇口から給水される原水の流路を切り替える弁であり、切替弁12に入った原水は、切替レバー15の回転角度によって、原水ストレート、原水シャワー、カートリッジ3への原水供給のいずれかの形態で吐出する。
The switching valve 12 is a valve that switches the flow path of the raw water supplied from the faucet. The raw water that has entered the switching valve 12 is supplied to the raw water straight, the raw water shower, and the raw water supply to the cartridge 3 according to the rotation angle of the switching lever 15. Discharge in any form.
切替弁12を通過した原水は、切替弁12の原水吐水部に着脱可能に取り付けられた吐水キャップ17から外部に吐出する。吐水キャップ17は原水ストレート吐出口と原水シャワー吐出口を有し、原水ストレートと原水シャワーの形状は、吐水キャップ17により形成される。
The raw water that has passed through the switching valve 12 is discharged to the outside from a water discharge cap 17 that is detachably attached to the raw water discharge portion of the switching valve 12. The water discharge cap 17 has a raw water straight discharge port and a raw water shower discharge port, and the shapes of the raw water straight and the raw water shower are formed by the water discharge cap 17.
ここで、本実施形態における切替器2とは、カートリッジ3と保護カバー4を除き、蛇口に取り付けて使用される組立体を意味する。
Here, the switching device 2 in the present embodiment means an assembly that is used by being attached to a faucet, except for the cartridge 3 and the protective cover 4.
切替器2は蛇口先端に取り付けて使用するため、通水時にシンクから跳ね返った汚れが裏側に付着しやすい。本実施形態の切替器2は少なくとも切替器2の下方を覆う保護カバー4を有しているため、保護カバー4を取り外して洗浄することで、切替器2を蛇口に取り付けたまま切替器2の裏側の汚れを洗浄することができる効果がある。ここで、下方とは、底面図で表したときに図面で表現できる範囲をいう。
Since the switch 2 is attached to the tip of the faucet, dirt that bounces off from the sink when water flows is likely to adhere to the back side. Since the switch 2 of this embodiment has the protective cover 4 which covers at least the lower part of the switch 2, the protective cover 4 is removed and washed, so that the switch 2 can be attached to the faucet while the switch 2 is attached to the faucet. There is an effect that dirt on the back side can be washed. Here, the downward direction means a range that can be expressed in the drawing when expressed in a bottom view.
一般に、蛇口直結型浄水器では、原水の吐出はストレート状とシャワー状を選択できるタイプが多く、原水ストレート状と原水シャワー状の吐出口は、一般的に切替器の下面に設けられている。
Generally, in the faucet direct connection type water purifier, there are many types in which the raw water discharge can be selected between a straight shape and a shower shape, and the raw water straight shape and the raw water shower shape discharge port are generally provided on the lower surface of the switch.
このため、蛇口に取り付けて長期間使用すると、シンクで洗浄水や洗剤などが跳ね返り、汚れやバイオフィルムが原水シャワーの穴に詰まり、流量が低下する問題があった。また、水道配管中の異物が切替器側から原水シャワーの穴に詰まる問題もあった。
For this reason, when attached to a faucet and used for a long time, there was a problem that washing water, detergent, etc. bounced back in the sink, and dirt and biofilm clogged in the holes of the raw water shower, resulting in a decrease in flow rate. In addition, there is a problem that foreign matter in the water pipe is clogged in the hole of the raw water shower from the switcher side.
特許文献2には原水出口用ノズル(吐水キャップ)を取り外して洗浄できる構造が記載されている。しかし、切替弁外側のケースカバーを縦断分割とし、それぞれの下側のおねじに原水出口用ノズルを螺合しているため、原水出口用ノズルから水漏れがないように、前後のケースカバーと切替弁と原水出口用ノズルの4部材を精度良く成形し組み立てる必要があり、成形品の収率が低くなる問題があった。また、4部材を水密に組み立てる必要があり、洗浄後の組み立て困難な問題があった。
Patent Document 2 describes a structure in which a raw water outlet nozzle (water discharge cap) can be removed and washed. However, the case cover on the outside of the switching valve is divided vertically, and the raw water outlet nozzle is screwed into the lower male thread of each, so that there is no water leakage from the raw water outlet nozzle. There is a problem that the four members of the switching valve and the raw water outlet nozzle need to be accurately molded and assembled, resulting in a low yield of the molded product. Further, it is necessary to assemble the four members in a watertight manner, and there is a problem that it is difficult to assemble after washing.
特許文献である特開2008-173538公報には、ケースカバーを上下方向に分割する案が記載されている。しかし、ケースカバーの下側にあたる下部ボディーと切替弁と原水シャワー吐出口(吐水キャップ)の3部材の調整があり、問題解決には至らなかった。
Japanese Patent Laid-Open No. 2008-173538, which is a patent document, describes a plan for dividing the case cover in the vertical direction. However, there were adjustments in the three parts of the lower body under the case cover, the switching valve, and the raw water shower discharge port (water discharge cap), which did not solve the problem.
本発明では、上述のような問題点に鑑み、以下に示すように、着脱可能な吐水キャップを、組み立てやすい2部材の組み合わせで構成する浄水器を提供することができる。
In the present invention, in view of the above-described problems, as shown below, a water purifier can be provided that includes a detachable water discharge cap composed of a combination of two members that can be easily assembled.
本実施形態では吐水キャップ17を取り外して洗浄することができるため、原水シャワー吐出口の多数のシャワー孔に詰まった汚れを取り除き、流量を回復させることができる。従来品は製品の外側からシャワー孔の洗浄を行っていたため、孔の詰まりを一時的に解消することはできても、詰まりの原因がシャワー孔より上流に滞留するためすぐに再度詰まる問題があった。本実施形態では、吐水キャップ17を取り外してシャワー孔より上流に滞留していた詰まりの原因を完全に洗い流して除去することにより、目詰まりの発生頻度を大幅に下げることができる。
In the present embodiment, since the water discharge cap 17 can be removed and cleaned, dirt clogged in many shower holes of the raw water shower discharge port can be removed, and the flow rate can be recovered. In the conventional product, the shower holes are washed from the outside of the product, so even though the clogging of the holes can be temporarily eliminated, the cause of the clogging stays upstream from the shower holes, so there is a problem of clogging immediately. It was. In the present embodiment, the occurrence frequency of clogging can be greatly reduced by removing the water discharge cap 17 and completely washing away the cause of the clogging staying upstream from the shower hole.
本実施形態では、吐水キャップ17を切替弁12に接続した。下カバー14に取り付ける従来の構造では、原水が部材間から漏れ出すことを防ぐために、切替弁12と下カバー14と吐水キャップ17の少なくとも3部材の成形精度を高め、少なくとも3部材の位置決めをした上で装着することで水密状態をつくる必要があった。これに対し本実施形態では、吐水キャップ17と切替弁12の2部材だけで水密状態が作られており、成形品の収率が高まる点および容易に水密状態を作れる利点がある。
In the present embodiment, the water discharge cap 17 is connected to the switching valve 12. In the conventional structure attached to the lower cover 14, in order to prevent raw water from leaking out between the members, the molding accuracy of at least three members of the switching valve 12, the lower cover 14, and the water discharge cap 17 is increased, and at least the three members are positioned. It was necessary to create a watertight state by wearing it above. On the other hand, in this embodiment, the watertight state is made only with two members, the water discharge cap 17 and the switching valve 12, and there exists an advantage which the yield of a molded article increases and can make a watertight state easily.
本実施形態では、吐水キャップ17に原水ストレートと原水シャワーの2種類の吐出口を設けた。原水は主に食器洗浄時に使用され、勢いよく洗い流せる原水ストレートと、広範囲を一度に洗い流せる原水シャワーを使い分けされる傾向があるため、浄水器にも複数種類の吐出形態を有することが求められる。吐水キャップ17に複数種類の吐出口を設けたため、すべての種類の吐出口を洗浄することが可能となり、切替器2をより一層衛生的に維持することができる。
In this embodiment, the water discharge cap 17 is provided with two types of discharge ports, a raw water straight and a raw water shower. Since raw water is mainly used when washing dishes, and there is a tendency to use either a raw water straight that can be washed out vigorously or a raw water shower that can wash out a wide area at once, the water purifier is also required to have a plurality of discharge forms. Since a plurality of types of discharge ports are provided in the water discharge cap 17, all types of discharge ports can be cleaned, and the switch 2 can be maintained more sanitary.
切替器2について図1から図13を用いて説明する。
The switch 2 will be described with reference to FIGS.

Two raw water discharge channels are provided: a raw water straight channel 53 formed inside the inner cylinder, and a raw water shower channel 54 formed in an annular portion between the inner cylinder and the outer cylinder. An inner O-ring 55 is attached to the outer periphery of the inner cylinder, and an outer O-ring 56 is attached to the outer periphery of the outer cylinder.
次に、吐水キャップ17について、説明する。
Next, the water discharge cap 17 will be described.
吐水キャップ17は、図8のように円環状底面71と、略円環の底面から連なる内側の側面72と外側の側面73と、円環状底面71および外側の側面73からなだらかに連なるヘラ状のツマミ74を有する。吐水キャップ17に、少なくとも1本の指が掛けられ、吐水キャップ17の外周方向に押圧することで吐水キャップ17を回転可能とする指掛け部を有するツマミ74を、吐水キャップ17の外周側に設けている。吐水キャップを確実に回すことを可能とし、吐水キャップ17の着脱を容易かつ確実とする。ツマミ74は外側の側面73から連なる形状でも良く、円環状底面71から連なる形状でも良く、吐水キャップ74の外周側に設けることが好ましい。
As shown in FIG. 8, the water discharge cap 17 has an annular bottom surface 71, an inner side surface 72 and an outer side surface 73 continuous from the bottom surface of the substantially annular ring, and a spatula-like shape continuously connected from the annular bottom surface 71 and the outer side surface 73. A knob 74 is provided. Provided on the outer peripheral side of the water discharge cap 17 is a knob 74 having a finger hook portion that allows at least one finger to be hung on the water discharge cap 17 and to rotate the water discharge cap 17 by pressing in the outer peripheral direction of the water discharge cap 17. Yes. The water discharge cap can be reliably rotated, and the water discharge cap 17 can be attached and detached easily and reliably. The knob 74 may have a shape that continues from the outer side surface 73 or may have a shape that continues from the annular bottom surface 71, and is preferably provided on the outer peripheral side of the water discharge cap 74.
外側の側面73の内壁にはバヨネット用の凸75が設けられている。吐水キャップ17は、切替弁12のバヨネット溝52に沿ってバヨネット用の凸75を移動させることで、二重の円筒形状になっている切替弁12の原水吐水部51に取り付けられる。その際、外側の側面73は、切替弁12の外側Oリング56を介して外側円筒と水密に接続され、原水シャワー流路54を形成する。吐水キャップ17における円環状底面71には多数の孔が環状に配され、原水をシャワー状に吐出するための原水シャワー吐出口となっている。
A convex 75 for bayonet is provided on the inner wall of the outer side surface 73. The water discharge cap 17 is attached to the raw water discharge portion 51 of the switching valve 12 having a double cylindrical shape by moving the bayonet protrusion 75 along the bayonet groove 52 of the switching valve 12. At that time, the outer side surface 73 is watertightly connected to the outer cylinder via the outer O-ring 56 of the switching valve 12 to form the raw water shower channel 54. A large number of holes are annularly formed on the annular bottom surface 71 of the water discharge cap 17, and serve as a raw water shower discharge port for discharging raw water in a shower shape.
吐水キャップ17における内側の側面72より内側は、切替弁12の内側Oリング55を介して内側円筒と水密に接続され、原水ストレート流路53を形成し、原水をストレート状に吐出するための原水ストレート吐出口となっている。
The inner side of the water discharge cap 17 from the inner side surface 72 is connected to the inner cylinder in a watertight manner via the inner O-ring 55 of the switching valve 12 to form a raw water straight flow path 53, and raw water for discharging the raw water in a straight shape. Straight outlet.
ツマミ74は板バネ76と保護カバー4を固定する固定溝77を有する。保護カバー4の切替器2に当接する面に設けた固定凸82を、吐水キャップ17の固定溝77に嵌めることで、保護カバー4を切替器2に固定することができる。保護カバー4の固定方法は、凸と凹だけでなく、凸と凸を引っ掛けるなど固定できる形状であれば特に指定はない。
The knob 74 has a fixing groove 77 for fixing the leaf spring 76 and the protective cover 4. The protective cover 4 can be fixed to the switch 2 by fitting the fixing protrusion 82 provided on the surface of the protective cover 4 that contacts the switch 2 into the fixing groove 77 of the water discharge cap 17. The fixing method of the protective cover 4 is not particularly specified as long as it is not only convex and concave, but can be fixed by hooking the convex and convex.
板バネ76はなくても良いが、固定溝77の手前を板バネ76とすることで、保護カバー4を繰り返し着脱した場合も、板バネ76がない形状よりも固定凸82が削れにくく、保護カバー4を切替器2に固定する力を長く維持できる効果がある。
The leaf spring 76 may not be provided. However, by using the leaf spring 76 in front of the fixing groove 77, even when the protective cover 4 is repeatedly attached and detached, the fixing protrusion 82 is less likely to be scraped than the shape without the leaf spring 76, thereby protecting the plate. There is an effect that the force for fixing the cover 4 to the switch 2 can be maintained for a long time.
保護カバー4を切替器2に固定するための固定溝77は切替器2にあれば良く、必ずしも吐水キャップ17に設ける必要はない。本実施形態では吐水キャップ17に原水ストレートおよび原水シャワーの形状を作る孔を設けているため、吐水キャップ17を取り付けて使用することで、原水形状が整う。保護カバー4を切替器2に固定するための固定溝77を吐水キャップ17に設けているため、吐水キャップ17未装着の状態では保護カバー4が取り付けられず、吐水キャップ17の取り付け忘れを防ぐことができる。
The fixing groove 77 for fixing the protective cover 4 to the switch 2 may be in the switch 2 and is not necessarily provided in the water discharge cap 17. In this embodiment, since the water discharge cap 17 is provided with holes for forming the shape of the raw water straight and the raw water shower, the raw water shape is adjusted by attaching the water discharge cap 17 and using it. Since the fixing cap 77 for fixing the protective cover 4 to the switching device 2 is provided in the water discharge cap 17, the protective cover 4 cannot be attached when the water discharge cap 17 is not attached, and forgetting to attach the water discharge cap 17 is prevented. Can do.
一般的な歯ブラシの毛の太さは約0.2mmであるため、原水シャワー吐出口のシャワー孔の孔径を0.2mmより大きく設計すると、孔の中まで洗浄しやすい効果がある。
Since the thickness of the bristles of a typical toothbrush is about 0.2 mm, if the diameter of the shower hole of the raw water shower discharge port is designed to be larger than 0.2 mm, it is easy to clean the inside of the hole.
また、ツマミ74を、切替器2の外縁まで延在する形状としても良い。ツマミ74の先端が吐水キャップ回転中心から遠くなるため、てこの原理より、小さい力で吐水キャップを回すことが可能となる。特に、ツマミ74を手前側外縁まで延在する形状とすると、いっそう操作しやすい形状となる。また、ツマミ74を長くすると、保護カバー4を取り外して吐水キャップ17を回転させた際に、吐水キャップ17の回転角度によって、図9のように切替器2の外縁より外側にツマミ74をはみ出させることができる。このはみ出している位置を吐水キャップ17の装着開始位置とすると、切替器2を上から見た際にツマミ74が見えているため、吐水キャップ17を取り付けやすい利点がある。さらには、ツマミ74と切替器2に印を付け、それぞれの印が並ぶ吐水キャップ17と切替器2の配置が、切替弁12に対する吐水キャップ17の装着開始位置としておくと、吐水キャップ17の装着開始位置を容易にみつけることができる効果もある。
Also, the knob 74 may have a shape that extends to the outer edge of the switch 2. Since the tip of the knob 74 is far from the center of rotation of the water discharge cap, the water discharge cap can be rotated with a small force by the lever principle. In particular, if the knob 74 has a shape that extends to the outer edge on the near side, the shape becomes easier to operate. Further, when the knob 74 is lengthened, when the protective cover 4 is removed and the water discharge cap 17 is rotated, the knob 74 protrudes outside the outer edge of the switch 2 as shown in FIG. 9 depending on the rotation angle of the water discharge cap 17. be able to. If this protruding position is the mounting start position of the water discharge cap 17, the knob 74 can be seen when the switch 2 is viewed from above, so that there is an advantage that the water discharge cap 17 can be easily attached. Furthermore, if the knob 74 and the switch 2 are marked, and the arrangement of the water discharge cap 17 and the switch 2 in which the respective marks are arranged is the mounting start position of the water discharge cap 17 with respect to the switching valve 12, the water discharge cap 17 is mounted. There is also an effect that the starting position can be easily found.
吐水キャップ17を厚さ5mm以上とすると握ったり指をかけたりしやすく、吐水キャップ17の着脱操作が行いやすく好ましい。特に吐水キャップ17をバヨネットでなくネジで取り付ける場合には、指がかかりやすいため操作しやすく便利である。また、指に当たる面積が大きくなるため、指あたりが優しく、操作時の痛みを取り除くことができる。
It is preferable that the water discharge cap 17 has a thickness of 5 mm or more because the water discharge cap 17 can be easily gripped and applied, and the water discharge cap 17 can be easily attached and detached. In particular, when the water discharge cap 17 is attached with a screw instead of a bayonet, it is easy to operate because it is easy to apply a finger. Moreover, since the area which hits a finger | toe becomes large, a finger contact is gentle and the pain at the time of operation can be removed.
バヨネット機構を用いて吐水キャップ17を着脱する構造では、吐水キャップ17のツマミ74だけに指をかけて力を加え、吐水キャップ17を外すことが想定される。バヨネット溝を、斜めに開口しているため、吐水キャップ17を回転させるだけで斜め下向きに取り外すことができる。本実施形態では、バヨネット溝の取り外しを誘導する溝側面において、開口する手前1mm程度を回転軸と平行にした。吐水キャップ17を回転させながら斜め下向きに取り外すのではなく、略鉛直下向きにだけ誘導することで、吐水キャップ17を静かに使用者の手に落とすことができる。
In the structure in which the water discharge cap 17 is attached and detached using the bayonet mechanism, it is assumed that the water discharge cap 17 is removed by applying a force only to the knob 74 of the water discharge cap 17 with a finger. Since the bayonet groove is opened obliquely, the bayonet groove can be removed obliquely downward simply by rotating the water discharge cap 17. In this embodiment, on the side surface of the groove that guides the removal of the bayonet groove, about 1 mm before opening is made parallel to the rotation axis. Instead of removing the water discharge cap 17 obliquely downward while rotating, the water discharge cap 17 can be gently dropped onto the user's hand by guiding it substantially vertically downward.
本実施形態では、吐水キャップ17に少なくとも1本の指がかけられるツマミ74を設け、ツマミ74を押圧することで吐水キャップ17を回転させ、着脱させる手法としたが、吐水キャップ17の外周面に2つ以上の平面や凹を設け、平面や凹をつかむことで吐水キャップ17を回転させ着脱させる形状であっても良い。平面や凹をつくることで、つかみやすく力を入れやすい効果を得る。
In the present embodiment, the water discharge cap 17 is provided with a knob 74 on which at least one finger can be put, and the water discharge cap 17 is rotated and detached by pressing the knob 74. A shape in which two or more planes and recesses are provided and the water discharge cap 17 is rotated and attached by grasping the planes and recesses may be used. By creating a flat surface and a concave, it is easy to grasp and exert an effect.
吐水キャップ17の外周面を平面のみで形成する形状であっても良い。たとえば吐水キャップ17の外周の断面を正六角形とすると、吐水キャップ17が固く締め付けられた場合でもスパナや六角レンチなどで取り外すことも可能となる。
The shape which forms the outer peripheral surface of the water discharge cap 17 only by a plane may be sufficient. For example, if the cross section of the outer periphery of the water discharge cap 17 is a regular hexagon, even if the water discharge cap 17 is firmly tightened, it can be removed with a spanner or a hexagon wrench.
本実施形態では、ヘラ状のツマミ74を設けたが、指がかけられる形状であれば良く、棒状や、指がかけやすいように水平断面に窪みを有する凸などであっても良い。
In this embodiment, the spatula-shaped knob 74 is provided. However, it may be any shape that can be applied to a finger, and may be a rod shape or a convex having a depression in a horizontal section so that the finger can be easily applied.
また、吐水キャップ17の中央に、一本の直線を凹で設け、その凹みにコインを押し当て回すことで、吐水キャップ17の着脱を行う手法も容易であり好ましい。
In addition, it is also preferable because a method of attaching and detaching the water discharge cap 17 by providing a straight line in the center of the water discharge cap 17 and pushing a coin against the recess is easy and preferable.
本実施形態では、吐水キャップ17を切替弁12に取り付ける手法としてバヨネットを採用したが、ネジを用いて取り付けても良い。吐水キャップ17にツメを設け、切替弁12の原水吐水部51内周に凸を設け、吐水キャップ17のツメを内側にたわませながら原水吐水部51に差し込み、ツメを原水吐水部51内周の凸に引っ掛けることで吐水キャップ17を取り付ける機構でも良い。逆に、原水吐水部51の外周に凸を設け、吐水キャップ17のツメを外側にたわませながら吐水キャップ17を取り付ける機構でも良い。同様に、ツメを原水吐水部に設け、ツメを引っ掛ける凸を吐水キャップ17に設けても良い。
In the present embodiment, a bayonet is adopted as a method of attaching the water discharge cap 17 to the switching valve 12, but it may be attached using a screw. A claw is provided on the water discharge cap 17, a protrusion is provided on the inner periphery of the raw water discharge portion 51 of the switching valve 12, and the claw of the water discharge cap 17 is inserted into the raw water discharge portion 51 while bending the claw of the water discharge cap 17. The mechanism which attaches the water discharge cap 17 by hooking on the convex of may be sufficient. Conversely, a mechanism may be provided in which a convex is provided on the outer periphery of the raw water discharge unit 51 and the water discharge cap 17 is attached while the claw of the water discharge cap 17 is bent outward. Similarly, a claw may be provided in the raw water discharge part, and a protrusion for hooking the claw may be provided in the water discharge cap 17.
下カバー14の下面に、切替器2を蛇口に取り付けた状態で上向きに凹む窪みを、図10のように設け、窪みの範囲を少なくとも吐水キャップ17の設置範囲、および、図9(b)(c)のように吐水キャップ17に設けられたツマミ74の可動範囲とした。吐水キャップ17を切替器2の厚さの範囲内に収納することができ、切替器2の厚さを薄くすることができる。シンクと蛇口の距離が狭いシンクでも、蛇口下を広く使用できる利便性がある。また、裏側(下面)窪みを、原水が挿通可能な中央の穴から径方向に10mm以上の幅で設けると、吐水キャップ17を着脱する際に指が入る空間とすることができる。ツマミ74がない場合も、吐水キャップ17をしっかり握ることができるため操作がしやすい。
On the lower surface of the lower cover 14, a recess that is recessed upward with the switch 2 attached to the faucet is provided as shown in FIG. 10, and the range of the recess is at least the installation range of the water discharge cap 17, and FIG. The movable range of the knob 74 provided on the water discharge cap 17 was set as shown in c). The water discharge cap 17 can be accommodated within the thickness range of the switch 2, and the thickness of the switch 2 can be reduced. Even a sink with a narrow distance between the sink and the faucet can be used widely under the faucet. Moreover, when a back side (lower surface) dent is provided with a width of 10 mm or more in the radial direction from a central hole through which raw water can be inserted, a space for a finger to enter when the water discharge cap 17 is attached or detached can be provided. Even when the knob 74 is not provided, the water discharge cap 17 can be firmly grasped, so that the operation is easy.
ネジ機構を用いて吐水キャップ17の着脱を行う構造の場合、吐水キャップ17の着脱に際し、吐水キャップ17を一周以上回転させることが多いため、裏側窪みは原水が挿通可能な中央の穴の周り全周にあると、着脱しやすい効果がある。
In the case of a structure in which the water discharge cap 17 is attached / detached using a screw mechanism, the water discharge cap 17 is often rotated one or more times when the water discharge cap 17 is attached / detached, so that the back side depression is entirely around the central hole through which raw water can be inserted. If it is in the circumference, there is an effect that it is easy to attach and detach.
バヨネット機構を用いて吐水キャップ17の着脱を行う構造の場合、吐水キャップ17およびツマミ74の可動域だけに裏側窪みを設けても良い。この場合、吐水キャップ17を切替器2の厚さの範囲内に収納することができるだけでなく、裏側窪みを設けない内部容量が大きい部分に、流量カウント機能やカートリッジの交換時期表示機能を作動させるための電池を嵌める電池ボックスなどを収納できる利点がある。
In the case of a structure in which the water discharge cap 17 is attached and detached using a bayonet mechanism, a back side depression may be provided only in the movable range of the water discharge cap 17 and the knob 74. In this case, not only can the water discharge cap 17 be accommodated within the thickness range of the switch 2, but also the flow rate counting function and the cartridge replacement time display function are activated in a portion with a large internal capacity that does not have a back side depression. Therefore, there is an advantage that a battery box or the like in which a battery is fitted can be stored.
また、吐水キャップ17の可動範囲の両サイドに、さらに指が入る隙間ができるように裏側窪みを広げると、吐水キャップ17着脱の際に、吐水キャップ17と切替器2との間で指を挟んだりすることを予防できる利点がある。
In addition, if the back side depression is widened so that a gap can be further inserted on both sides of the movable range of the water discharge cap 17, the finger is sandwiched between the water discharge cap 17 and the switch 2 when the water discharge cap 17 is attached or detached. There is an advantage that can be prevented.
切替弁12の原水吐水部51に装着する内側Oリングと外側Oリングは、切替弁12と吐水キャップ17を水密にする役割を担うため、重要である。吐水キャップ17を取り外した際に現れる内側Oリング55と外側Oリング56を、取り外し困難であるようOリング装着溝の深さおよび幅を決定すると、Oリングの落下や紛失を予防することができる。
The inner O-ring and the outer O-ring attached to the raw water discharge part 51 of the switching valve 12 are important because they play a role of making the switching valve 12 and the water discharge cap 17 watertight. When the depth and width of the O-ring mounting groove are determined so that it is difficult to remove the inner O-ring 55 and the outer O-ring 56 that appear when the water discharge cap 17 is removed, it is possible to prevent the O-ring from dropping or being lost. .
本実施形態では、切替弁12の原水吐水部51と吐水キャップ17をOリングの外周を径方向に潰すことで水密状態としたが、原水吐水部51と吐水キャップ17の間に平パッキンを嵌め、パッキンを厚さ方向に潰すことで水密状態としても良い。
In this embodiment, the raw water discharge part 51 and the water discharge cap 17 of the switching valve 12 are made watertight by crushing the outer periphery of the O-ring in the radial direction, but a flat packing is fitted between the raw water discharge part 51 and the water discharge cap 17. The watertight state may be obtained by crushing the packing in the thickness direction.
吐水キャップ17の上流に配する整流部材も、その目的のためには、必要である。ここで言う整流部材とは、原水ストレートの形状を整える役割を担うメッシュや原水シャワー形状を整える役割を担う整流板などを指す。整流部材は吐水キャップ17を取り外した際に現れるが、切替弁12内部への装着や、一体成形、溶着により、切替弁12に固着させているため取り外すことができず、紛失を予防することができる。
A rectifying member disposed upstream of the water discharge cap 17 is also necessary for that purpose. The rectifying member here refers to a mesh that plays a role of adjusting the shape of the raw water straight, a rectifying plate that plays a role of adjusting the shape of the raw water shower, and the like. Although the rectifying member appears when the water discharge cap 17 is removed, it cannot be removed because it is fixed to the switching valve 12 by mounting, integral molding, or welding inside the switching valve 12, thus preventing loss. it can.
原水ストレート形状を整える整流部材として用いるメッシュは、原水ストレート流路53内における上流寄り(例えば、下流室30の原水ストレート流出口の直後)に設置することが好ましい。上流寄りに設置すると、シンクで跳ね返った汚れが原水ストレート吐出口に入った場合も、汚れがメッシュに付着しづらく、吐水キャップ17を洗浄するだけで、切替器2を衛生的に維持することができる。
It is preferable that the mesh used as a rectifying member for adjusting the raw water straight shape is installed upstream in the raw water straight channel 53 (for example, immediately after the raw water straight outlet of the downstream chamber 30). If installed near the upstream, even if dirt bounced off the sink enters the raw water straight discharge port, the dirt is difficult to adhere to the mesh, and the switch 2 can be maintained in a sanitary manner simply by washing the water discharge cap 17. it can.
整流板は、切替器2の原水シャワー流路54に出た原水を、吐水キャップ17の円環状底面71に均等に行き渡らせることで、原水シャワー形状を整える。整流板を円盤状とすれば、円盤の周方向に原水を拡散させることができるため、吐水キャップ17の円環状底面71に均等に行き渡らせることができる。また、整流板を複数の穴を円環状に設ける形状としても良い。吐水キャップ17を取り付け忘れた状態で使用した場合も、整流板自体がシャワー形状であるため、原水拡散により不用意に周囲の家財に水がかかることを防ぐことができる。
The straightening plate arranges the raw water shower shape by evenly spreading the raw water that has flowed out to the raw water shower channel 54 of the switch 2 to the annular bottom surface 71 of the water discharge cap 17. If the current plate is disk-shaped, raw water can be diffused in the circumferential direction of the disk, so that it can be evenly distributed to the annular bottom surface 71 of the water discharge cap 17. The rectifying plate may have a shape in which a plurality of holes are provided in an annular shape. Even when used in a state in which the water discharge cap 17 is forgotten to be attached, the current plate itself has a shower shape, so that it is possible to prevent water from being inadvertently applied to surrounding household goods due to raw water diffusion.
本実施形態では、上カバー13と下カバー14で切替弁12を挟む形態を切替器2と呼んだが、切替弁12の表面が切替器2の表層面を兼ねている場合など、上カバー13および下カバー14は必ずしも必要ではない。したがって、切替弁12が切替器2の下側表層面を形成している場合、下カバー14は不要であり、本実施形態で下カバー下面に設けた窪みは切替弁12の下面に設けると良い。
In the present embodiment, the mode in which the switching valve 12 is sandwiched between the upper cover 13 and the lower cover 14 is referred to as the switching device 2, but when the surface of the switching valve 12 also serves as the surface layer of the switching device 2, The lower cover 14 is not always necessary. Therefore, when the switching valve 12 forms the lower surface layer of the switching device 2, the lower cover 14 is unnecessary, and the depression provided on the lower surface of the lower cover in this embodiment is preferably provided on the lower surface of the switching valve 12. .
また、本実施形態では、下カバー14中央に、原水を挿通可能とする穴を円形状で設け、吐水キャップ17を装着する形態を記載したが、吐水キャップ17を着脱させる必要がない場合、下カバー14に原水ストレート吐出口や原水シャワー吐出口にあたる吐出口を設ければ良く、スリットやメッシュなど、どのような形態であっても良い。
Further, in the present embodiment, a mode in which a hole that allows raw water to be inserted is provided in a circular shape in the center of the lower cover 14 and the water discharge cap 17 is attached is described. The cover 14 may be provided with an outlet corresponding to the raw water straight outlet or the raw water shower outlet, and may be in any form such as a slit or a mesh.
切替器2は樹脂成形品であると製作しやすく安価である。樹脂材質としては、ポリスチレンやAS樹脂(アクリロニトリルスチレン樹脂)、ポリカーボネート、アクリル樹脂、ポリエチレン、ABS樹脂(アクリロニトリルブタジエンスチレン樹脂)、ポリプロピレンなどが使用可能である。特には、流路の切替を行う切替弁12は、シール機構を有し、繰り返し切替操作を行うことから、成形精度が良く摩擦に強いPOM(ポリオキシメチレン、ポリアセタール)が好ましい。上カバー13、下カバー14、切替レバー15、吐水キャップ17は、外観を担う部分であり、他部材との係合部が多いことから、成形精度や成形性が良く光沢のあるABS樹脂が好ましい。
The switch 2 is easy to manufacture and inexpensive if it is a resin molded product. As the resin material, polystyrene, AS resin (acrylonitrile styrene resin), polycarbonate, acrylic resin, polyethylene, ABS resin (acrylonitrile butadiene styrene resin), polypropylene, or the like can be used. In particular, the switching valve 12 for switching the flow path has a sealing mechanism and repeatedly performs switching operation. Therefore, POM (polyoxymethylene, polyacetal) having high molding accuracy and strong friction is preferable. The upper cover 13, the lower cover 14, the switching lever 15, and the water discharge cap 17 are parts responsible for the appearance, and since there are many engaging portions with other members, a glossy ABS resin with good molding accuracy and moldability is preferable. .
次に、保護カバー4について説明する。
Next, the protective cover 4 will be described.
保護カバー4は、図11、図12、図13のように切替器2の下面から側面に沿った肉薄の部材であり、切替器2に着脱可能に装備される。肉薄とは樹脂厚さ2mm以下を指す。切替器2と一体的な形状となることで、美観を保つことができる。
The protective cover 4 is a thin member along the side surface from the lower surface of the switch 2 as shown in FIGS. 11, 12, and 13, and is detachably mounted on the switch 2. Thinness refers to a resin thickness of 2 mm or less. The aesthetic appearance can be maintained by being integrated with the switch 2.
切替器2の表層が複数の部材から構成される場合、複数の部材のうち少なくとも隣り合う二部材の境界の一部を保護カバー4で覆うことで、境界が汚れることを防ぎ、手入れを楽にすることができる。つまり、切替器2の側面を覆っているため、上カバー13と下カバー14の境界を覆うことができ、切替器2で汚れがたまりやすく洗浄しづらかった上カバー13と下カバー14の境界に汚れがたまることを防ぐ効果がある。同様に、下カバー14が複数の部材で構成される場合、下カバー14を担う複数の部材の境界を保護カバー4で覆うことで、境界が汚れることを防ぐ効果がある。
When the surface layer of the switching device 2 is composed of a plurality of members, covering the boundary between at least two adjacent members of the plurality of members with the protective cover 4 prevents the boundary from becoming dirty and facilitates maintenance. be able to. That is, since the side surface of the switch 2 is covered, the boundary between the upper cover 13 and the lower cover 14 can be covered, and the boundary between the upper cover 13 and the lower cover 14 that is easily collected by the switch 2 and difficult to clean. There is an effect to prevent accumulation of dirt. Similarly, when the lower cover 14 is composed of a plurality of members, covering the boundaries of the plurality of members that bear the lower cover 14 with the protective cover 4 has an effect of preventing the boundaries from becoming dirty.
同様に、本実施形態のように、上カバー13と液晶表示16の境界など、複数の隣接する部材同士の境界を保護カバー4で覆うと、異物や汚れがたまりやすい箇所を減らすことができ、衛生的に使用できる。
Similarly, as in the present embodiment, when the boundary between a plurality of adjacent members such as the boundary between the upper cover 13 and the liquid crystal display 16 is covered with the protective cover 4, it is possible to reduce the number of places where foreign matter and dirt tend to accumulate, Can be used hygienically.
保護カバー4を切替器2の前面、背面、左右の側面のうち一面を覆わない形状とすると、保護カバー4を水平方向に動かすだけで着脱できて簡単である。切替器2の背面を覆わない形状とすると、切替器の前面の方向に引くことで保護カバー4を取り外すことができる構造となり、保護カバー4のデザインを左右対称とすることができるため、美観をつくることができる。
If the protective cover 4 has a shape that does not cover one of the front, back, and left and right side surfaces of the switch 2, it can be easily attached and detached by simply moving the protective cover 4 in the horizontal direction. If the shape of the switch 2 is not covered, the protective cover 4 can be removed by pulling in the direction of the front of the switch, and the design of the protective cover 4 can be made symmetrical.

保護カバー4の下面に指掛け凸83を設けているため、保護カバー4に指が掛かりやすく手前に引きやすい効果がある。指掛け凸83は保護カバー4に指がかかりやすければ良く、窪みで形成されても良い。
Since the finger hooking projection 83 is provided on the lower surface of the protective cover 4, there is an effect that the protective cover 4 can be easily hooked with fingers. The finger hooking protrusion 83 may be formed as a depression as long as the finger is easily put on the protective cover 4.
保護カバー4は樹脂成形品であると製作しやすく安価であり、かつ、切替器2に繰り返し着脱する際の傷が少ない利点がある。樹脂材質としては、ポリスチレンやAS樹脂(アクリロニトリルスチレン樹脂)、ポリカーボネート、アクリル樹脂、ポリエチレン、ABS樹脂(アクリロニトリルブタジエンスチレン樹脂)、ポリプロピレンなどが使用可能である。保護カバー4は肉薄であるため、柔軟性に富むポリプロピレンであると破損しづらく好ましい。また、ABS樹脂を用いると、塗装やメッキ、印刷など、装飾しやすい利点がある。
If the protective cover 4 is a resin molded product, it is easy to manufacture and inexpensive, and has the advantage that there are few scratches when it is repeatedly attached to and detached from the switch 2. As the resin material, polystyrene, AS resin (acrylonitrile styrene resin), polycarbonate, acrylic resin, polyethylene, ABS resin (acrylonitrile butadiene styrene resin), polypropylene, or the like can be used. Since the protective cover 4 is thin, it is preferable that it is hard to break if it is a polypropylene having a high flexibility. In addition, when ABS resin is used, there is an advantage that it is easy to decorate, such as painting, plating and printing.
本実施形態の保護カバー4の形状は、保護カバー4中央に孔81のみを設け、切替器2に設けた原水ストレート吐出口や原水シャワー吐出口により原水形状を形成したが、保護カバー4に原水ストレート吐出口と原水シャワー吐出口があっても良い。この場合、保護カバー4が吐水キャップ17の機能を兼ねる。略円環の底面と、底面から連なる内側面と外側面を有し、切替弁12の原水吐水部51と水密に接続される。吐水キャップ17が不要な分、安価に構成できる。また、洗浄部品が減るため、使用者の手入れも楽になる利点があって好ましい。
The shape of the protective cover 4 of the present embodiment is such that only the hole 81 is provided at the center of the protective cover 4 and the raw water shape is formed by the raw water straight discharge port or the raw water shower discharge port provided in the switch 2. There may be a straight outlet and a raw water shower outlet. In this case, the protective cover 4 also functions as the water discharge cap 17. It has a substantially annular bottom surface, an inner side surface and an outer side surface continuous from the bottom surface, and is watertightly connected to the raw water discharge portion 51 of the switching valve 12. Since the water discharge cap 17 is unnecessary, it can be configured at low cost. Further, since there are fewer cleaning parts, there is an advantage that the user can easily care for it, which is preferable.
本実施形態では、保護カバー4を切替器2にスライドして装着し、吐水キャップ17の板バネ76奥の固定溝77に固定する形態を採用したが、その他にも、切替器2の原水吐水部51を中心にネジやバヨネットを用いて切替器2に下から装着しても良く、市販のネジやボルトを用いて切替器2に固定しても良い。また、ゴムなど伸縮性のある素材を用いたバンドを取り付けた保護カバー4を、バンドを用いて切替器2に固定しても良い。保護カバー4と切替器2の一方にツメを設け、もう一方に凸を設け、ツメをたわませて保護カバー4と切替器2を装着し、凸にツメを引っ掛けて固定しても良い。
In the present embodiment, the protective cover 4 is slid and attached to the switch 2 and fixed to the fixing groove 77 at the back of the leaf spring 76 of the water discharge cap 17. The switch 51 may be mounted from below using screws or bayonet around the portion 51, or may be fixed to the switch 2 using commercially available screws or bolts. Moreover, you may fix the protective cover 4 which attached the band using elastic materials, such as rubber | gum, to the switch 2 using a band. A claw may be provided on one of the protective cover 4 and the switch 2, a convex may be provided on the other, the claw may be bent, the protective cover 4 and the switch 2 may be attached, and the claw may be hooked and fixed.
保護カバー4の着脱方向は、手前であると操作しやすいが、略鉛直方向とすると、奥行きの狭いシンクでも容易に着脱可能であり好ましい。一般に、原水吐水部51は切替器2の下側に鉛直下向きに伸びる円筒状で設けられる。この場合、原水吐水部51の軸方向と保護カバー4の着脱方向がほぼ平行であるため、保護カバー4中央に設けた原水を挿通可能とする孔81と原水吐水部51の隙間を小さくすることができる。保護カバー4を手前に引いて着脱する場合よりも保護カバー4で保護できる範囲を広くすることができる。
The attachment / detachment direction of the protective cover 4 is easy to operate if it is in front, but if it is substantially vertical, it is preferable that a sink with a narrow depth can be easily attached / detached. In general, the raw water discharge unit 51 is provided in a cylindrical shape extending vertically downward on the lower side of the switch 2. In this case, since the axial direction of the raw water spouting portion 51 and the attaching / detaching direction of the protective cover 4 are substantially parallel, the gap between the hole 81 through which the raw water provided at the center of the protective cover 4 can be inserted and the raw water spouting portion 51 is reduced. Can do. The range that can be protected by the protective cover 4 can be made wider than when the protective cover 4 is pulled forward and removed.
保護カバー4と切替器2の間を水密状態とすると、保護カバー4と切替器2の間に溜まる水や汚れによるカビや水垢などを防ぐことができるため好ましい。保護カバー4に水抜き穴を設けておくと、保護カバー4と切替器2の間に水が入ってしまった場合も、水抜きをすることができて良い。
It is preferable to make the space between the protective cover 4 and the switching device 2 watertight because it can prevent mold and dirt caused by water and dirt accumulated between the protective cover 4 and the switching device 2. If a water drain hole is provided in the protective cover 4, water can be drained even if water enters between the protective cover 4 and the switch 2.
本実施形態によれば、保護カバー4を一部材で安価に作製し、一方向に動かすだけで着脱できる形状を採用した。一方で、2つ以上の部材をヒンジで繋ぐなど保護カバー4に開閉機能を保持させると、一方向に動かす保護カバー4では覆いきれない切替器2の面、例えば全面を覆うことが可能となり、保護域を自由に選択できる利点がある。
According to the present embodiment, the protective cover 4 is produced with a single member at low cost, and a shape that can be attached and detached by moving it in one direction is adopted. On the other hand, if the protective cover 4 has an opening / closing function such as connecting two or more members with a hinge, the surface of the switch 2 that cannot be covered by the protective cover 4 moved in one direction, for example, the entire surface can be covered. There is an advantage that the protected area can be freely selected.
切替器2を略円筒状とする場合、保護カバー4も内側にめねじを有する略円筒形状とし、切替器2の外周に設けたおねじに取り付けると、コンパクトに強力に保護カバー4を取り付けることができる。
When the switching device 2 is substantially cylindrical, the protective cover 4 is also formed in a substantially cylindrical shape having a female screw on the inner side, and when attached to the male screw provided on the outer periphery of the switching device 2, the protective cover 4 is attached compactly and strongly. Can do.
カートリッジ3を切替器2の内部に収納するなど、切替器2が、蛇口取り付け位置から背面側が長い形状である場合、保護カバー4を切替器2の背面側に嵌め込む形状としても良い。この場合、保護カバー4を取り外すだけで、手が届きにくい背面や背面側下面の汚れを洗浄することができる利点がある。
When the switching device 2 has a long shape on the back side from the faucet mounting position, such as storing the cartridge 3 in the switching device 2, the protective cover 4 may be fitted on the back side of the switching device 2. In this case, there is an advantage that it is possible to clean the back surface and the back side lower surface that are difficult to reach by simply removing the protective cover 4.
保護カバー4はカートリッジ3に取り付ける構造でも良い。例えば図1のようにカートリッジ3が切替器2の側方に位置する場合、カートリッジ3の側面に複数の凸を設け、保護カバー4を凸にかけて固定し、切替器2の下方を覆う形状としても良い。同様に凸の代わりにツバやツメを設けても良い。
The protective cover 4 may be attached to the cartridge 3. For example, when the cartridge 3 is located on the side of the switch 2 as shown in FIG. 1, a plurality of protrusions are provided on the side surface of the cartridge 3, the protective cover 4 is fixed on the protrusion, and the lower part of the switch 2 is covered. good. Similarly, a brim or claw may be provided instead of the convex.
カートリッジ3が切替器2の内部に収納される場合などは、切替器2に浄水吐出口が設けられることが多い。原水の吐出口だけでなく浄水の吐出口も設けることで、切替器2の下面全体を保護カバー4で覆い保護することができる。
When the cartridge 3 is accommodated in the switch 2, a clean water discharge port is often provided in the switch 2. By providing not only the discharge port of raw water but also the discharge port of purified water, the entire lower surface of the switch 2 can be covered and protected by the protective cover 4.
本実施形態のように保護カバーで切替器2の下方を覆うことを目的とする場合、切替弁12から下カバー14を着脱できる構造とし、下カバー14に保護カバー4の機能を持たせても良い。下カバー14を複数部材で構成し、最も衛生的に維持したい原水吐水部51周縁を含む部材を着脱できる構造としても良い。原水形状を形成する吐出口は切替弁12に設けても良く、吐水キャップ17を設けても良い。また、原水形状を形成する吐出口を保護カバー機能を有する下カバーや、原水吐水部51周縁を含む下カバーの一部材に設けることで、下カバー14に、保護カバーと吐水キャップの機能を持たせても良い。いずれの場合も構成部材を減らすことができ、浄水器を安価かつコンパクトにできる効果がある。
When it is intended to cover the lower part of the switch 2 with a protective cover as in this embodiment, the lower cover 14 can be attached to and detached from the switching valve 12, and the function of the protective cover 4 can be given to the lower cover 14. good. It is good also as a structure which comprises the lower cover 14 with a some member and can attach or detach the member containing the periphery of the raw | natural water discharge part 51 which wants to maintain most hygienically. The discharge port forming the raw water shape may be provided in the switching valve 12 or a water discharge cap 17 may be provided. Moreover, the lower cover 14 has the functions of a protective cover and a water discharge cap by providing the discharge port forming the raw water shape in one member of the lower cover having a protective cover function and the lower cover including the periphery of the raw water discharge part 51. May be allowed. In either case, the number of constituent members can be reduced, and the water purifier can be made inexpensive and compact.
保護カバー4をシリコーンなど伸縮性の高い樹脂で形成し、保護カバー4を伸ばして下カバー14の外周にひっかけて固定する構造でも良い。切替弁12の原水吐水部51に固定できる例えば円筒などの固定成形部材を設け、固定成形部材の外側をシリコーン樹脂で形成すると、保護カバー4の位置決めや取り付けを容易とすることができる。また、シリコーン樹脂性保護カバー4の伸ばし方が悪く原水形状を乱す懸念を解消することもできる。さらには、吐水キャップ17の外側をシリコーン樹脂で形成すると、保護カバー4と吐水キャップ17を1つの部材としてつくることができる。一度に洗浄できる利点がある。
The protective cover 4 may be formed of a highly elastic resin such as silicone, and the protective cover 4 may be stretched and hooked onto the outer periphery of the lower cover 14 to be fixed. If a fixed molding member such as a cylinder that can be fixed to the raw water discharge portion 51 of the switching valve 12 is provided and the outer side of the fixed molding member is formed of silicone resin, positioning and attachment of the protective cover 4 can be facilitated. In addition, it is possible to eliminate the concern that the silicone resin protective cover 4 is stretched poorly and disturbs the raw water shape. Furthermore, if the outside of the water discharge cap 17 is formed of silicone resin, the protective cover 4 and the water discharge cap 17 can be made as one member. There is an advantage that can be washed at once.
本実施形態は、シンクから跳ね返った汚れから切替器2の裏側を保護し、切替器2の裏側にあたる部分の洗浄を手軽に実施できることを目的としたが、保護カバー4が蛇口と切替器2の接続部を覆う形態であっても良い。
The purpose of this embodiment is to protect the back side of the switcher 2 from dirt bounced off from the sink and to easily clean the portion corresponding to the back side of the switcher 2, but the protective cover 4 is provided between the faucet and the switcher 2. The form which covers a connection part may be sufficient.
蛇口と取り付けナット11と切替器2が該当する蛇口と切替器2の接続部には、部材同士の隙間や凹凸が多い。隙間や凹みに埃や食品汚れなどがたまりやすく、従来品は頻度よく洗浄しなくてはならない問題があった。保護カバー4が蛇口と切替器2の接続部を覆う形態であれば、保護カバー4だけを取り外して洗浄することで、簡単に、切替器2を衛生的かつ美しく維持することができる。例えば、保護カバー4を1枚の薄い成形品で作製し、先端を落とした円錐状に巻きつけるような形状を採用すると、着脱が容易な上、開いて洗浄できるため使いやすい利点がある。また、空洞のドーナツ型を半分に割ったようなリング状のカバーとすれば、高さの低い保護カバー4とすることができる。上記のように埃や食品汚れなど、水洗いで落としづらい汚れを防ぐことができるだけでも、切替器2を簡単に衛生的かつ美しく維持することができるが、さらに、蛇口と保護カバー4の接続部にシール性を持たせると、水垢の発生も抑制することができて好ましい。
There are many gaps and irregularities between members in the connection portion of the faucet and the switching device 2 to which the faucet, the mounting nut 11 and the switching device 2 correspond. Dust and food stains are likely to accumulate in the gaps and dents, and the conventional product has a problem that it must be frequently cleaned. If the protective cover 4 covers the connection portion between the faucet and the switch 2, the switch 2 can be easily maintained hygienically and beautifully by removing and cleaning only the protective cover 4. For example, if the protective cover 4 is made of a thin molded product and is wound around a cone having a tip dropped, it is easy to use because it can be easily detached and opened and cleaned. Moreover, if it is set as the ring-shaped cover which divided the hollow donut type | mold into half, it can be set as the protective cover 4 with low height. The switch 2 can be easily maintained in a hygienic and beautiful manner as long as it can prevent dirt that is difficult to remove by washing, such as dust and food, as described above. Providing a sealing property is preferable because generation of scale can be suppressed.
同様に、従来製品において、上カバー13と液晶表示16の境界も異物や汚れがたまりやすく、洗浄しづらい問題があった。本実施形態では、保護カバー4を切替器2の裏側保護を目的として切替器2の下方に取り付けたが、切替器2の上面上方にスライド嵌めこみにより取り付け、切替器2の上面を保護する形状としても良い。
Similarly, in the conventional product, there is a problem that the boundary between the upper cover 13 and the liquid crystal display 16 is liable to collect foreign matter and dirt, and is difficult to clean. In this embodiment, the protective cover 4 is attached below the switch 2 for the purpose of protecting the back side of the switch 2. However, the protective cover 4 is mounted on the upper surface of the switch 2 by slide fitting to protect the top surface of the switch 2. It is also good.
また、保護カバー4として、液晶表示よりも大きいフィルムを用いて液晶表示周辺も覆うことで、異物や汚れたまりを防ぎ、洗浄しやすい製品を実現することができる。フィルムを何重にも貼り付け、汚れたら一番上のフィルムを剥ぎ取って美しくすることも可能だが、上カバー13に張り付きやすい素材のフィルムや、貼って剥がせる粘着剤付きのフィルムなどを採用し、汚れたら洗浄して再度貼り付け、繰返し使用することができれば、安価な上にゴミ削減にもなるため好ましい。
Also, as the protective cover 4, a film larger than the liquid crystal display is used to cover the periphery of the liquid crystal display, so that a product that is easy to clean can be realized by preventing foreign matter and dirt accumulation. It is possible to apply multiple layers of film and peel off the top film if it gets dirty, making it beautiful. However, a film made of a material that easily sticks to the upper cover 13 or a film with an adhesive that can be applied and removed is used. If it becomes dirty, it can be washed and pasted again, and it can be used repeatedly.
保護カバー4は、切替器2の汚れを予防して洗浄を簡潔化する目的を達成すれば良く、例えば成形品に限らず、フィルムを貼り付ける形態やシリコーンゴムを伸ばして巻きつける形態であっても良い。
The protective cover 4 only needs to achieve the purpose of preventing the change of the switch 2 and simplifying the cleaning. For example, the protective cover 4 is not limited to a molded product, and is a form in which a film is pasted or a silicone rubber is stretched and wound. Also good.
その他、保護カバー4に、液体をはじきやすい材質を用いたり撥水コーティングを施したりすると、保護カバー4自体に防汚効果と洗浄しやすい効果を持たせることができる。また、抗菌コーティングを施したり抗菌剤入りの樹脂を用いたりすると、繰返し洗浄によりキズが付いた場合も菌が発生しにくく保護カバー4自体を衛生的に使用できる。さらに、保護カバー4に着色やデザイン性を持たせることで、浄水器自体の美観を付加することもできる。
In addition, if the protective cover 4 is made of a material that easily repels liquid or is provided with a water-repellent coating, the protective cover 4 itself can have an antifouling effect and an easy-to-clean effect. In addition, when an antibacterial coating is applied or a resin containing an antibacterial agent is used, even when scratches are caused by repeated washing, the protective cover 4 itself can be used in a sanitary manner because bacteria are hardly generated. Furthermore, the beauty of the water purifier itself can be added by giving the protective cover 4 coloring and design.
本実施形態では、カートリッジの交換寿命の表示手段に液晶表示を記載したが、その他、カレンダー表示などの機構であっても良い。
In the present embodiment, the liquid crystal display is described as the cartridge replacement life display means, but other mechanisms such as a calendar display may be used.
本実施形態では、吐水キャップ17を切替弁12に着脱可能に取り付けられる部材とし、原水ストレートや原水シャワーの形状を吐水キャップ17によって形成する構成としたが、吐水キャップ17を設けず、原水ストレートや原水シャワーの形状を下カバー14によって形成する構成であっても、保護カバー4の効果を得ることができる。
In the present embodiment, the water discharge cap 17 is a member that is detachably attached to the switching valve 12 and the raw water straight or the shape of the raw water shower is formed by the water discharge cap 17, but the water discharge cap 17 is not provided, Even if the shape of the raw water shower is formed by the lower cover 14, the effect of the protective cover 4 can be obtained.
本実施形態によれば、吐水キャップ17には原水の吐出口を設けたが、浄水吐出口にも応用することができ、さらには原水と浄水双方の吐出口を設ける形態であっても好ましい。原水の吐出口と浄水の吐出口を個別の部材で設けても良いが、一部材であれば、安価であり、また、使用者も一度に原水吐出口と浄水吐出口の両方を洗浄できるため利便性が高い。
According to the present embodiment, the water discharge cap 17 is provided with the raw water discharge port, but it can also be applied to the purified water discharge port, and it is also preferable that the discharge port for both the raw water and the purified water is provided. The raw water discharge port and the purified water discharge port may be provided as separate members, but if one member is used, it is inexpensive and the user can clean both the raw water discharge port and the purified water discharge port at the same time. Convenience is high.
本発明は、浄水器に限らずストレート状吐水やシャワー状吐水を有する水栓などにも応用することができるが、その応用範囲が、これらに限られるものではない。
The present invention can be applied not only to the water purifier but also to a faucet having straight water discharge or shower water discharge, but the application range is not limited thereto.
