Description

【0001】
【発明の属する技術分野】
この発明は、シャワヘッドに関するものである。
【0002】
【従来の技術および発明が解決しようとする課題】
シャワヘッドに粉末または液体の芳香剤や、固形の芳香剤を収納したものがあるけれども、いずれも水溶性のため放出される香りの持続期間が短いという欠点がある。また、これら芳香剤を交換操作が簡単なケースに収納した、いわゆるカートリッジ式のシャワヘッドは前記ケース分だけサイズが大型化するという欠点がある。
【0003】
この発明はこのような実情を考慮に入れてなされたものであって、大型化することなく香りを持続できるシャワヘッドを提供することを目的としている。
【0004】
【課題を解決するための手段】
この発明は上述の課題を解決するための手段を以下のように構成している。
すなわち、この発明のシャワヘッドは、シャワヘッド本体の吐水口の開放端に着脱自在に装着される吐水キャップを備えたシャワヘッドにおいて、前記吐水キャップの裏面側に軟質樹脂製の吐水板を設け、この吐水板に香りを放つ芳香成分を含ませてあり、
さらに、前記吐水板は、香りを放つ芳香樹脂よりなるペレットと、前記吐水板の原料となる軟質樹脂よりなるペレットとを混合し、この混合したものを加熱、溶融させた後、金型を用いて樹脂成形されてなるものである。
【0005】
また、この発明は別の観点から、シャワヘッド本体の吐水口の開放端に着脱自在に装着される樹脂製の吐水キャップを備えたシャワヘッドにおいて、前記吐水キャップに香りを放つ芳香成分を含ませてあり、
さらに、前記吐水キャップは、香りを放つ芳香樹脂よりなるペレットと、前記吐水キャップの原料となる樹脂よりなるペレットとを混合し、この混合したものを加熱、溶融させた後、金型を用いて樹脂成形されてなるものであることを特徴とするシャワヘッドを提供する。
【0006】
【発明の実施の形態】
図1、図2は、この発明の好ましい一実施形態を示す。
【0007】
図1、図2において、1は、シャワヘッドで、下流側のシャワヘッド本体2とこのシャワヘッド本体2から上流側に連設されたグリップ部3を有する。シャワヘッド本体2とグリップ部3は硬質の樹脂で形成されている。
【0008】
シャワヘッド1には、図外の湯水混合栓や蛇口などに接続する給水路が形成されている。また、シャワヘッド本体2は、この下流側に吐水口4が形成されている。そして、この吐水口4の開放端4aに吐水キャップ5がビス6により着脱自在に装着されている。吐水キャップ5も硬質の樹脂で形成されている。10は、ビス6が螺合するねじ部で、シャワヘッド本体2の背面部2aから開放端4aに向かって延設されている。
【0009】
前記吐水キャップ5は、平面視円形で、中央部にビス6が挿通するビス挿通穴部5aを有するとともに、ビス挿通穴部5aのまわりに、吐水口2に導入された水あるいは湯水混合水がシャワーとして散水される多数の散水孔(吐水孔)7を有する。この実施形態では、三つの同心円上にそれぞれ複数個の散水孔7が所定間隔で形成されている。散水孔7が形成される吐水キャップ5の面は表面8および裏面9とも表面側に緩やかに湾曲した湾曲面をなす。
【0010】
以下、この発明の特徴的構成について説明する。
【0011】
11は、シリコン樹脂製の吐水板で、吐水キャップ5の裏面側に着脱自在に設けられている。この吐水板11には、香りを放つ芳香成分を含ませてある。吐水板11は、変形自在な軟質の薄肉状環状板で、中央にビス挿通穴部5aに外側から嵌込まれる嵌込孔部12を有し、吐水キャップ5に形成した散水孔7に対応する位置に通水孔部13を有する。すなわち、吐水板11には、前記嵌込孔部12のまわりの三つの同心円上にそれぞれ複数個の前記通水孔部13が所定間隔で形成されている。また、前記各通水孔部13は、前記散水孔7に挿通可能な長さに突出した筒状部分13aを前記吐水板11の前面11a側に有する。この実施形態では、筒状部分13aは、筒状部分13aの先端Eが吐水キャップ5の表面8から僅かに突出するよう突出長さが設定されている。
【0012】
そして、ビス挿通穴部5aに嵌込孔部12を嵌込むとともに、吐水板11の前面11aが吐水キャップ5の裏面9に当接するまで筒状部分13aを散水孔7に挿通させることで吐水キャップ5の裏面9側に吐水板11が装着され、この状態で、吐水口4の開放端4aに吐水キャップ5がビス6により装着されうる。
【0013】
なお、散水孔7の形状にばらつきがあって整流状態の悪い散水孔7が形成されていても、筒状部分13aを散水孔7に挿通して設置することで、整流状態を良好にできる。また、通水孔部13は、変形自在な軟質のシリコン樹脂で薄肉に形成されているので、通水孔部13に付着したごみを直接手や布で取り除くことができ、硬質の吐水キャップ5の散水孔7が目詰まりを起こした場合に比して、容易な作業で目詰まりを解消できる利点を有する。
【0014】
また、香りを放つ芳香樹脂を予め多数のペレットに成形しておき、これらペレットと、シリコン樹脂よりなる多数のペレットとを所定の配合量にて混合し、この混合したものを加熱、溶融させた後、金型を用いて樹脂成形することにより環状体の吐水板11をうることができる。
【0015】
而して、吐水板11に香りを放つ芳香成分を含ませたので、カートリッジを不要にでき、シャワヘッド1の大型化を防止できる。
【0016】
また、吐水板11を用いることにより接水面積が増えるので、香りの効果を増大できる。
【0017】
更に、吐水板11に香りを放つ芳香成分を含ませてあるので、香りの持続期間を従来に比して延長できる。
【0018】
なお、上記実施形態では、吐水板11に香りを放つ芳香成分を含ませてたシャワヘッド1を示したが、この発明では、樹脂製の吐水キャップ5に香りを放つ芳香成分を含ませてもよい。すなわち、香りを放つ芳香樹脂を予め多数のペレットに成形しておき、これらペレットと、吐水キャップ5の原料となる樹脂よりなる多数のペレットとを所定の配合量にて混合し、この混合したものを加熱、溶融させた後、金型を用いて樹脂成形することにより吐水キャップ5をうることができる。この場合、使用する前記金型として、既存の吐水キャップの金型を利用できるので、イニシャルコストを不要にできる。
【0019】
更に、この発明には、香りを放つ芳香成分を吐水板11と樹脂製の吐水キャップ5に含ませたシャワヘッドも含まれる。この場合は、上記二つの実施形態よりも香りの効果を増大できる。
【0020】
【発明の効果】
以上説明したようにこの発明では、大型化することなく香りを持続できるシャワヘッドを提供することができる。

In FIG. 1 and FIG. 2, reference numeral 1 denotes a shower head, which has a shower head main body 2 on the downstream side and a grip portion 3 connected to the upstream side from the shower head main body 2. The shower head main body 2 and the grip part 3 are made of hard resin.
[0008]
The shower head 1 is formed with a water supply channel that is connected to a hot water / water mixer tap or a faucet (not shown). Further, the shower head body 2 has a water discharge port 4 formed on the downstream side. A water discharge cap 5 is detachably attached to the open end 4 a of the water discharge port 4 with screws 6. The water discharge cap 5 is also formed of a hard resin. Reference numeral 10 denotes a screw portion into which the screw 6 is screwed, and extends from the back surface portion 2a of the shower head main body 2 toward the open end 4a.
[0009]
The water discharge cap 5 has a circular shape in plan view, and has a screw insertion hole 5a through which a screw 6 is inserted at the center, and water or hot water mixed water introduced into the water discharge port 2 around the screw insertion hole 5a. It has many water spray holes (water discharge holes) 7 sprayed as a shower. In this embodiment, a plurality of water spray holes 7 are formed at predetermined intervals on three concentric circles. The surface of the water discharge cap 5 in which the water sprinkling holes 7 are formed has a curved surface that is gently curved toward the front surface with both the front surface 8 and the back surface 9.
[0010]
The characteristic configuration of the present invention will be described below.
[0011]
Reference numeral 11 denotes a water discharge plate made of silicon resin, which is detachably provided on the back side of the water discharge cap 5. The water discharge plate 11 contains an aromatic component that gives off a scent. The water discharge plate 11 is a deformable soft thin annular plate having a fitting hole portion 12 fitted from the outside into the screw insertion hole portion 5 a at the center, and corresponds to the water spray hole 7 formed in the water discharge cap 5. A water passage hole 13 is provided at the position. That is, the water discharge plate 11 has a plurality of water passage holes 13 formed at predetermined intervals on three concentric circles around the fitting hole 12. Further, each of the water passage holes 13 has a cylindrical portion 13 a protruding to a length that can be inserted into the water spray hole 7 on the front surface 11 a side of the water discharge plate 11. In this embodiment, the protruding length of the cylindrical portion 13 a is set so that the tip E of the cylindrical portion 13 a slightly protrudes from the surface 8 of the water discharge cap 5.
[0012]
And while inserting the fitting hole part 12 in the screw insertion hole part 5a, and inserting the cylindrical part 13a in the water spray hole 7 until the front surface 11a of the water discharging board 11 contact | abuts the back surface 9 of the water discharging cap 5, it is a water discharging cap. 5 is attached to the back surface 9 side, and in this state, the water discharge cap 5 can be attached to the open end 4 a of the water discharge port 4 with the screw 6.
[0013]
In addition, even if the shape of the water spray hole 7 varies and the water spray hole 7 having a poor rectification state is formed, the rectification state can be improved by inserting the cylindrical portion 13a through the water spray hole 7 and installing it. Further, since the water passage hole portion 13 is formed thin with a deformable soft silicone resin, the dust adhering to the water passage hole portion 13 can be directly removed by hand or cloth, and the hard water discharge cap 5 Compared to the case where the water spray hole 7 is clogged, there is an advantage that clogging can be eliminated by an easy operation.
[0014]
In addition, a fragrant aromatic resin was previously formed into a large number of pellets, these pellets and a large number of pellets made of silicon resin were mixed in a predetermined blending amount, and the mixture was heated and melted. Thereafter, an annular water discharge plate 11 can be obtained by resin molding using a mold.
[0015]
Thus, since the water discharge plate 11 contains an aromatic component that emits a scent, the cartridge can be made unnecessary, and the shower head 1 can be prevented from being enlarged.
[0016]
Moreover, since the water contact area increases by using the water discharging board 11, the effect of a fragrance can be increased.
[0017]
Furthermore, since the scent component which emits a fragrance is included in the water discharge plate 11, the duration of the scent can be extended as compared with the conventional case.
[0018]
In addition, in the said embodiment, although the shower head 1 which included the aromatic component which emits a fragrance in the water discharging board 11 was shown, in this invention, even if the aromatic component which emits a fragrance is included in the resin water discharging cap 5 Good. That is, a fragrant fragrance resin is molded into a large number of pellets in advance, and these pellets and a large number of pellets made of a resin that is a raw material of the water discharge cap 5 are mixed in a predetermined blending amount, and this mixture After being heated and melted, the water discharge cap 5 can be obtained by resin molding using a mold. In this case, since the existing water discharge cap mold can be used as the mold to be used, the initial cost can be eliminated.
[0019]
Furthermore, the present invention also includes a shower head in which a fragrant fragrance component is included in the water discharge plate 11 and the resin water discharge cap 5. In this case, the effect of the scent can be increased compared to the above two embodiments.
[0020]
