Description

本発明は、微細気泡を含んだ湯水を噴射するシャワーヘッドに関する。 The present invention relates to a shower head that injects hot water containing fine bubbles.

従来から、微細気泡を含んだ湯水を噴射する微細気泡発生機能付きシャワーヘッドが開示されている（ 例えば、特許文献１参照）。特許文献１のシャワーヘッドは、微細気泡生成機構を内蔵することで、噴射孔から微細気泡を含む湯水を皮膚に直接噴射することができ、皮膚の汚れを効果的に除去するものである。 Conventionally, a shower head with a fine bubble generation function for injecting hot water containing fine bubbles has been disclosed (see, for example, Patent Document 1). The shower head of Patent Document 1 has a built-in fine bubble generation mechanism, so that hot water containing fine bubbles can be directly sprayed onto the skin from the injection holes, and dirt on the skin is effectively removed.

特開２０１６−２２０９０９号公報Japanese Unexamined Patent Publication No. 2016-220909

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 shower head has a problem that a large amount of fine bubbles cannot be generated because the dissolved concentration of air is low, and a 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。 The present invention has been created in view of the above problems, and an object of the present invention is to provide a shower head capable of increasing the dissolution concentration of air, generating hot water containing many fine bubbles, and injecting hot water.

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 task was configured to generate fine bubbles by swirling a gas-liquid dissolving unit configured to stir hot water to increase the dissolution concentration of air and hot water agitated by the gas-liquid dissolving unit as a swirling flow. The fine bubble generating part can be solved by the shower head built 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 shower head body is composed of a grip portion having a hot water water introduction hole supplied from a mixing tap at one end and a tip portion provided with a sprinkler plate connected to the grip portion and ejecting hot water water. Consists of a melting chamber formed inside the grip portion and a stirring member arranged in the center of the melting chamber and extending in the longitudinal direction, and the stirring member of the gas-liquid melting portion has an introduction flow at the bottom and inside at the tip. By forming a bottomed tubular shape in which a path is formed and arranging the tip portion so as to face the introduction hole at a predetermined interval, the hot water supplied from the introduction hole is brought into contact with 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 agitate in this space, and a through hole is formed on the outer peripheral surface to communicate the melting chamber and the introduction flow path. It is preferable that the flow path communicates with the fine bubble generating portion.

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。 The gas-liquid dissolution stirring member preferably 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 fine bubble generating part are built in the shower head main body, the air for hot water can be mixed without installing a melting tank separately from the shower head. By increasing the dissolution concentration and then generating fine bubbles in this way, it is possible to provide a shower head capable of injecting hot water containing many fine bubbles.

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。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a shower head, which is a grip portion 3 for introducing hot water supplied from a mixing tap (not shown) and a grip portion 3 provided at the tip of the grip portion 3 for injecting hot water water introduced into the grip portion 3. The shower head main body 2 is composed of the head portion 4 and the head portion 4. A hose (not shown) extending from the mixing tap is connected to the end of the grip portion 3, and a hot water introduction hole 3a is provided at this end. The head portion 4 is provided with a sprinkler plate 5a having a plurality of sprinkler holes 5b bored on the front surface thereof, and is configured to inject hot water from the sprinkler holes 5b. In addition, in FIGS. 1 to 5, the arrow of the alternate long and short dash line 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 is swirled with a gas-liquid dissolving unit 10 configured to stir hot water to increase the dissolution concentration of air and hot water stirred by the gas-liquid dissolving unit 10. A fine bubble generating unit 20 configured to generate fine bubbles is built in.

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 dissolution unit 10 is built in the grip portion 3, and is composed of a dissolution chamber 11 formed inside the grip portion 3 and a stirring member 12 arranged in the central portion of the dissolution 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 portion 10 has a bottomed tubular shape having a bottom portion 12b at the tip portion 12a, and an introduction flow path 12c is formed inside.

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。 In the stirring member 12, the tip portion 12a is arranged so as to face the introduction hole 3a at a predetermined interval, and the stirring chamber 13 is formed by the outer peripheral surface of the stirring member 12 and the inner peripheral surface of the melting chamber 11. It is formed. Therefore, the hot water supplied from the introduction hole 3a flows toward the outside of the tip portion 12a and flows into the stirring chamber 13. The hot water that has flowed into the stirring chamber 13 is stirred as shown by the arrow indicated by the alternate long and short dash line to form a gas-liquid mixture in which the dissolved concentration of 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。 The tip portion 12a of the stirring member 12 is preferably formed in an umbrella shape. This is for narrowing the inlet to the stirring chamber 13 and setting the volume of the stirring chamber 13 wide. By doing so, the flow velocity of the hot water flowing into the stirring chamber 13 is increased, and the stirring efficiency is increased. Has 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。 Further, through holes 12d are formed at two places on the outer peripheral surface of the stirring member 12, and the stirring chamber 13 and the introduction flow path 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 flow path 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 fine bubble generating unit 20 is built in the head portion 4 of the shower head main body 2, is formed inside the head portion 4, and communicates with the introduction flow path 12c of the stirring member 12 and the swirling chamber 21. It is arranged in the central portion of the above, and is composed of a swirling flow generating unit 22 that 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 generation unit 22 has a substantially triangular pyramid, and the internal shape of the swirl chamber 21 is also formed along the outer shape thereof. The swirl flow generation unit 22 is arranged with the outer peripheral surface facing the upstream side, and a plurality of upstream swirl blades 22a are integrally formed on the outer peripheral surface thereof.

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 swirling flow generating unit 22 has a plurality of downstream swivel blades 22b integrally molded on the bottom surface, and the swirling blades 22a and 22b allow hot water to flow into the swirling chamber 21. It becomes a swirling flow as shown by the arrow of the alternate long and short dash line.

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, a lead-out flow path 23 is communicated with the outlet of the swirl chamber 21, and a plurality of slits 24 are branched from the lead-out flow path 23. Since these slits 24 have a reduced diameter, the flow velocity of the hot water (gas-liquid mixture) increases when passing through the slit 24, and fine bubbles are generated in the hot water due to the shearing force. Further, a punching metal 25 is surrounded at the outlet of the slit 24, and the fine bubbles contained in the hot water that has passed through the slit 24 are further subdivided. Then, as shown in FIG. 1, hot water containing fine bubbles is sprayed from the sprinkler hole 5a of the sprinkler plate 5 to the outside.

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。 The circulation pipe 26 may be built in the lead-out flow path 23. The circulation pipe 26 is provided with through holes 26a and 26b at the top and bottom, and takes in hot water in the lead-out flow path 23 from the downstream through hole 26a and discharges it from the upstream through hole 26b. In this way, the circulation pipe is configured to increase the dissolution concentration of the gas by circulating hot water in the lead-out flow path 23.

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 unit 10 is built in, the dissolution concentration of air in hot water can be increased without installing a dissolution tank separately from the shower head. Then, by generating fine bubbles with hot water having a high dissolved concentration of air, it becomes possible to generate many fine 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。 Further, the gas-liquid dissolving unit 10 is configured to agitate the hot water around the stirring member 12, that is, the shower head 1 is configured to agitate the hot water on the outside inside the grip portion 3. Even if the stirring chamber 13 is not full of hot water when tilted, the stirring chamber 13 stores the hot water, so that the stirring efficiency does not decrease. Further, the through hole 12d of the stirring member 12 is provided at a position on the side surface with respect to the sprinkler plate 5. Therefore, even if the inside of the stirring chamber 13 is not full when the shower head 1 is tilted so that the sprinkler plate 5 faces downward, the hot water can be supplied from the stirring chamber 13 to the introduction flow path 12c, so that the injection can be performed. There is no stopping.

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 can be made without departing from the spirit of the present invention.
