しかしながら、上記シャワーヘッドでは、空気の溶解濃度が低いため、微細気泡を多く生成することができず、所望の効果を得られない問題を有していた。 However, the above-described showerhead has a problem in that it cannot generate a large number of microbubbles due to the low dissolved concentration of air, and the desired effect cannot be obtained.

本発明は、上記問題に鑑みて創生されたものであり、空気の溶解濃度を高め、多くの微細気泡を含む湯水を生成し噴射可能なシャワーヘッドを提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a shower head capable of increasing the concentration of dissolved air and generating and jetting hot and cold water containing many microbubbles.

上記課題は、湯水を撹拌して空気の溶解濃度を高めるように構成された気液溶解部と、気液溶解部によって撹拌された湯水を旋回流にして微細気泡を生成するように構成された微細気泡生成部とをシャワーヘッド本体に内蔵したシャワーヘッドによって解決できる。 The above problem is solved by a gas-liquid dissolving unit configured to agitate hot water to increase the dissolved concentration of air, and a system configured to turn the hot water stirred by the gas-liquid dissolving unit into a swirling flow to generate microbubbles. This problem can be solved by using a shower head that incorporates a fine bubble generating part in the shower head body.

なお、シャワーヘッド本体は、一端に混合栓から供給される湯水の導入孔を備える把持部と、この把持部に連結され、湯水を噴射する散水板を備える先端部とから成り、気液溶解部は、把持部の内部に形成された溶解室と、溶解室の中心部に配置され長手方向に延びる撹拌部材とから成り、気液溶解部の撹拌部材は、先端部に底部および内部に導入流路が形成された有底筒状を成し、先端部を導入孔に対して所定の間隔をおいて対向させるように配置することにより、導入孔から供給された湯水を撹拌部材の外周面と溶解室の内周面とによって形成される空間へ流入させてこの空間で撹拌するように構成されるとともに、外周面には溶解室と導入流路とを連通させる貫通孔が穿設され、導入流路は微細気泡生成部と連通させてあることが好ましい。 The main body of the shower head consists of a grip portion having an introduction hole for hot water supplied from a mixing valve at one end, and a tip portion connected to this grip portion and having a sprinkling plate for spraying hot water, and a gas-liquid dissolving portion. consists of a dissolving chamber formed inside the grip and a stirring member arranged in the center of the dissolving chamber and extending in the longitudinal direction. It has a bottomed cylindrical shape with a channel formed therein, and is arranged so that the tip faces the introduction hole at a predetermined distance, so that the hot water supplied from the introduction hole is directed to the outer peripheral surface of the stirring member. It is configured to flow into the space formed by the inner peripheral surface of the melting chamber and stir in this space, and the outer peripheral surface is provided with a through hole for communicating the melting chamber and the introduction channel. It is preferable that the channel communicates with the microbubble generator.

なお、気液溶解の撹拌部材は、先端部の外形が傘状に成形されていることが好ましい。 It is preferable that the gas-liquid dissolving stirring member has an umbrella-shaped outer shape at the tip.

本発明のシャワーヘッドによれば、シャワーヘッド本体に、気液溶解部と微細気泡生成部との双方が内蔵されているので、シャワーヘッドとは別に溶解タンクを設置せずとも、湯水に対する空気の溶解濃度が高められ、このようにしてから微細気泡を生成することにより、多くの微細気泡を含む湯水を噴射可能なシャワーヘッドを提供することができる。 According to the shower head of the present invention, since both the gas-liquid dissolving part and the micro-bubble generating part are built in the shower head body, there is no need to install a dissolving tank separately from the shower head. By increasing the dissolution concentration and generating microbubbles in this way, it is possible to provide a shower head capable of spraying hot water containing many microbubbles.

以下、図面に基づいて本発明の実施形態を説明する。図１において、１はシャワーヘッドであり、混合栓（図示せず）から供給される湯水を導入する把持部３と、把持部３の先端に設けられ、把持部３に導入された湯水を噴射するヘッド部４とからシャワーヘッド本体２が構成されている。把持部３は、端部に混合栓から延びるホース（図示せず）が接続され、この端部には湯水の導入孔３ａが設けてある。ヘッド部４は、前面に、複数の散水孔５ｂが穿設された散水板５ａを備えており、散水孔５ｂから湯水を噴射するように構成されている。なお、図１乃至図５において、二点鎖線の矢印は、湯水の流れる方向を示すものである。 An embodiment of the present invention will be described below based on the drawings. In FIG. 1, reference numeral 1 denotes a shower head, which includes a grip portion 3 for introducing hot water and cold water supplied from a mixer tap (not shown), and a tip portion of the grip portion 3 that injects the hot water introduced into the grip portion 3. A shower head main body 2 is composed of the head portion 4 and the shower head portion 4 . A hose (not shown) extending from a mixing valve is connected to the end of the gripping portion 3, and a hot water introduction hole 3a is provided at the end. The head portion 4 has a sprinkler plate 5a having a plurality of sprinkler holes 5b on its front surface, and is configured to spray hot water from the sprinkler holes 5b. In addition, in FIGS. 1 to 5, the two-dot chain line arrow indicates the direction in which hot water flows.

図２に示すように、シャワーヘッド本体２には、湯水を撹拌して空気の溶解濃度を高めるように構成された気液溶解部１０と、気液溶解部１０によって撹拌された湯水を旋回流にして微細気泡を生成するように構成された微細気泡生成部２０とが内蔵されている。 As shown in FIG. 2, the shower head main body 2 includes a gas-liquid dissolving section 10 configured to agitate hot water to increase the dissolved concentration of air, and a swirling flow of hot water stirred by the gas-liquid dissolving section 10. and a micro-bubble generator 20 configured to generate micro-bubbles.

気液溶解部１０は、把持部３に内蔵されており、把持部３の内部に形成された溶解室１１と、溶解室１１内の中心部に配置され、長手方向に延びる撹拌部材１２とから構成されている。 The gas-liquid dissolving part 10 is built in the grip part 3 and consists of a dissolving chamber 11 formed inside the grip part 3 and a stirring member 12 arranged in the central part of the dissolving chamber 11 and extending in the longitudinal direction. It is configured.

気液溶解部１０の撹拌部材１２は、先端部１２ａに底部１２ｂを有する有底筒状を成しており、内部には導入流路１２ｃが形成されている。 The stirring member 12 of the gas-liquid dissolving section 10 has a bottomed tubular shape having a bottom portion 12b at a tip portion 12a, and an introduction channel 12c is formed therein.

撹拌部材１２は、先端部を１２ａを導入孔３ａに対して所定の間隔をおいて対向させるように配置するとともに、撹拌部材１２の外周面と溶解室１１の内周面とによって撹拌室１３が形成される。このため、導入孔３ａから供給された湯水は、先端部１２ａの外側に向かって流れ、撹拌室１３へ流入する。撹拌室１３へ流入した湯水は、二点鎖線で示す矢印のように撹拌され、空気の溶解濃度が高められた気液混合体となる。 The stirring member 12 is arranged so that the tip 12a faces the introduction hole 3a with a predetermined gap therebetween, and the stirring chamber 13 is defined by the outer peripheral surface of the stirring member 12 and the inner peripheral surface of the dissolving chamber 11. It is formed. Therefore, the hot water supplied from the introduction hole 3 a flows toward the outside of the tip portion 12 a and flows into the stirring chamber 13 . The hot water that has flowed into the stirring chamber 13 is stirred as indicated by the two-dot chain line arrows, and becomes a gas-liquid mixture in which the concentration of dissolved air is increased.

なお、撹拌部材１２の先端部１２ａは、傘状に成形されていることが好ましい。これは、撹拌室１３への入口を狭くするとともに、撹拌室１３の容積を広く設定するためのものであり、このようにすることで、撹拌室１３へ流入する湯水の流速を高め、撹拌効率を高める効果がある。 It should be noted that the tip portion 12a of the stirring member 12 is preferably shaped like an umbrella. This is for narrowing the entrance to the stirring chamber 13 and setting the volume of the stirring chamber 13 wide. have the effect of increasing

また、撹拌部材１２の外周面には、２箇所に貫通孔１２ｄが穿設されており、撹拌室１３と導入流路１２ｃとを連通する。このため、撹拌室１３によって撹拌された湯水は、貫通孔１２ｄを通過して導入流路１２ｃへ流入する。 Two through holes 12d are formed in the outer peripheral surface of the stirring member 12, and the stirring chamber 13 and the introduction channel 12c are communicated with each other. Therefore, the hot water stirred by the stirring chamber 13 passes through the through hole 12d and flows into the introduction channel 12c.

微細気泡生成部２０は、シャワーヘッド本体２のヘッド部４に内蔵されており、ヘッド部４の内部に成形され、撹拌部材１２の導入流路１２ｃと連通する旋回室２１と、この旋回室２１の中心部に配置され、旋回流を発生させる旋回流生成部２２とから構成されている。 The microbubble generating part 20 is built in the head part 4 of the shower head main body 2, and is molded inside the head part 4. and a swirling flow generating section 22 which is arranged at the center of the and generates a swirling flow.

図３に示すように、旋回流生成部２２は、略三角錐を成しており、その外形に沿うように旋回室２１の内部形状も成形されている。旋回流生成部２２は、外周面を上流側に向けて配置されており、その外周面には、複数の上流側旋回翼２２ａが一体成形されている。 As shown in FIG. 3, the swirl flow generator 22 has a substantially triangular pyramid shape, and the inner shape of the swirl chamber 21 is formed along the outer shape thereof. The swirl flow generator 22 is arranged with its outer peripheral surface facing upstream, and a plurality of upstream swirl vanes 22a are integrally formed on its outer peripheral surface.

また、図４に示すように、旋回流生成部２２は、底面に一体成形された複数の下流側旋回翼２２ｂを有しており、これら旋回翼２２ａ，２２ｂによって、湯水は、旋回室２１内で二点鎖線の矢印で示すような旋回流になる。 Further, as shown in FIG. 4, the swirl flow generating section 22 has a plurality of downstream swirl vanes 22b integrally formed on the bottom surface. At , a swirling flow is obtained as indicated by the two-dot chain line arrow.

図５に示すように、旋回室２１の出口には、導出流路２３が連通されており、この導出流路２３からは、複数のスリット２４が分岐している。これらスリット２４は縮径されているため、スリット２４を通過する際に湯水（気液混合体）の流速が増大し、せん断力によって湯水に微細気泡が生成される。また、スリット２４の出口にはパンチングメタル２５が包囲してあり、スリット２４を通過した湯水に含まれる微細気泡をさらに細分化する。そして、図１に示すように、散水板５の散水孔５ａから外部へ微細気泡を含む湯水が噴射される。 As shown in FIG. 5, the exit of the swirling chamber 21 is communicated with a lead-out channel 23, and a plurality of slits 24 branch from the lead-out channel 23. As shown in FIG. Since the diameter of these slits 24 is reduced, the flow velocity of the hot water (gas-liquid mixture) increases when passing through the slits 24, and fine air bubbles are generated in the hot water due to the shear force. Also, the exit of the slit 24 is surrounded by a punching metal 25, which further subdivides fine air bubbles contained in the hot water that has passed through the slit 24. - 特許庁Then, as shown in FIG. 1, hot water containing microbubbles is sprayed outside from the water spray holes 5a of the water spray plate 5. As shown in FIG.

なお、導出流路２３には、循環パイプ２６を内蔵させてもよい。この循環パイプ２６は、上下に貫通穴２６ａ，２６ｂを備えており、下流側貫通穴２６ａから導出流路２３内の湯水を内部へ取り込み、上流側貫通穴２６ｂから放出するものである。このように、循環パイプは導出流路２３内で湯水を循環させることにより、気体の溶解濃度を高めるように構成されている。 A circulation pipe 26 may be incorporated in the outlet flow path 23 . The circulation pipe 26 is provided with through holes 26a and 26b on the upper and lower sides, and takes in the hot water in the lead-out passage 23 from the downstream side through hole 26a and discharges it from the upstream side through hole 26b. In this manner, the circulation pipe is configured to circulate hot water in the outlet flow path 23 to increase the dissolved concentration of the gas.

上記シャワーヘッド１によれば、気液溶解部１０が内蔵されているので、シャワーヘッドとは別に溶解タンクを設置せずとも、湯水に対する空気の溶解濃度が高められる。そして、空気の溶解濃度が高められた湯水で微細気泡を生成することにより、多くの微細気泡を生成することが可能となる。 According to the shower head 1, since the gas-liquid dissolving part 10 is built in, the dissolution concentration of air in hot water can be increased without installing a dissolving tank separately from the shower head. By generating fine air bubbles with hot water in which the concentration of dissolved air is increased, it is possible to generate a large number of fine air bubbles.

また、気液溶解部１０は、撹拌部材１２の周囲で湯水を撹拌するように構成されており、つまり把持部３の内部において外側で湯水を撹拌するように構成されているため、シャワーヘッド１を傾けた際に撹拌室１３に湯水が満水でない状態でも、撹拌室１３には湯水が貯水されるので、撹拌効率が低下することはない。さらに、撹拌部材１２の貫通孔１２ｄは、散水板５に対して側面となる位置に設けられている。このため、散水板５を下に向けるようにシャワーヘッド１を傾けた際に撹拌室１３の内部に湯水が満水でない状態でも、撹拌室１３から導入流路１２ｃへ湯水を供給できるので、噴射が止むようなことはない。 In addition, since the gas-liquid dissolving part 10 is configured to stir hot water around the stirring member 12, that is, it is configured to stir hot water outside the inside of the grip part 3, the shower head 1 Even if the stirring chamber 13 is not full of hot water when tilting, the stirring efficiency is not lowered because hot water is stored in the stirring chamber 13.例文帳に追加Furthermore, the through hole 12 d of the stirring member 12 is provided at a side surface with respect to the sprinkler plate 5 . Therefore, even if the inside of the stirring chamber 13 is not filled with hot water when the shower head 1 is tilted so that the sprinkler plate 5 faces downward, hot water can be supplied from the stirring chamber 13 to the introduction channel 12c. It never stops.

なお、本発明の各部の具体的な構成は、上述した実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々変形が可能である。 The specific configuration of each part of the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the gist of the present invention.
