Description

本発明は、湯水を霧状に発生させることができるミスト発生装置に関するものであり、特にシャワー流とミスト流とを切り換えることができるミスト発生装置である。   The present invention relates to a mist generator capable of generating hot water in a mist, and more particularly, a mist generator capable of switching between a shower flow and a mist flow.

従来より、家庭の浴室内において、入浴者の心をリラックスさせたり、肌の潤いを高めて心身の健康増進に役立たせることができるミスト発生装置が知られている。
また、浴室で用いられるミスト発生装置には、浴室暖房装置に設けられたもの(据え付け型)や、浴室の混合栓に接続できるもの(混合栓接続型)等がある。最近では、大掛かりな設置工事を必要とせず、比較的安価に購入できる混合栓接続型のものが人気である。例えば、その技術が特許文献1に開示されている。
2. Description of the Related Art Conventionally, there has been known a mist generating device that can relax a bather's heart in a bathroom of a home or enhance moisture of the skin to help improve physical and mental health.
Moreover, the mist generating device used in the bathroom includes a device provided in a bathroom heating device (installation type), a device that can be connected to a mixing tap in the bathroom (mixing plug connection type), and the like. Recently, a mixer plug connection type that does not require large-scale installation work and can be purchased relatively inexpensively is popular. For example, this technique is disclosed in Patent Document 1.

特許文献1のミスト発生装置は、シャワー装置の併用を可能とした装置であって、混合栓側から供給される湯水を導入する導入部と、ミストを噴射するミスト噴射部と、シャワー装置側に湯水を供給する吐出部と、装置内に供給された湯水の流れをミスト噴射部側かシャワー装置側のいずれかに切り換えることができる切換手段とを備えた構成とされている。即ち、特許文献1では、ミスト発生装置とシャワー発生装置が別々であり、ミスト装置自体にシャワーを噴射する機能は備えられていない。そして、特許文献1におけるミスト噴射部には、ミスト発生ノズル部材(以下、単にノズル部材とも称す)が取り付けられている。   The mist generating device of Patent Document 1 is a device that can be used in combination with a shower device, and includes an introduction unit that introduces hot water supplied from the mixing plug side, a mist injection unit that injects mist, and a shower device side. It is configured to include a discharge unit that supplies hot water and switching means that can switch the flow of hot water supplied into the device to either the mist injection unit side or the shower device side. That is, in Patent Document 1, the mist generating device and the shower generating device are separate, and the function of injecting a shower to the mist device itself is not provided. A mist generating nozzle member (hereinafter also simply referred to as a nozzle member) is attached to the mist injection section in Patent Document 1.

ところで、浴室内において、ミストによるサウナ効果、暖房効果、あるいはシャワー効果を十分に得るためには、ミストを一定量以上発生させる必要がある。また、1つのミスト噴射部から発生可能なミストの量には限界がある。そのため、ミストの量を増加させようとすれば、ミスト噴射部を数多く配置させる必要がある。   By the way, in a bathroom, in order to fully obtain the sauna effect, heating effect, or shower effect by mist, it is necessary to generate mist more than a certain amount. Further, there is a limit to the amount of mist that can be generated from one mist injection unit. Therefore, if it is going to increase the quantity of mist, it is necessary to arrange many mist injection parts.

しかしながら、特許文献1のようなミスト発生装置では、ミストの量を増加させるために、ノズル部材を数多く配置させる必要があり、一般的に高価とされるノズル部材の数を増やせばミスト発生装置の製造コストが増加するという不満があった。
また、ノズル部材を用いたミスト発生装置は、ノズル部材の数を増やすほど装置全体が大型化するため、浴室内を圧迫してしまう懸念があった。
However, in the mist generating device as in Patent Document 1, it is necessary to arrange a large number of nozzle members in order to increase the amount of mist. If the number of nozzle members which are generally expensive is increased, the mist generating device There were complaints that manufacturing costs would increase.
Moreover, since the mist generating apparatus using a nozzle member becomes large as the entire apparatus increases as the number of nozzle members increases, there is a concern that the inside of the bathroom may be compressed.

そこで、特許文献2では、ノズル部材を使用することなく、シャワー噴射部とミスト噴射部を1つのシャワーヘッド本体(以下、ヘッド本体とも称す)に一体的に形成し、切換手段によりヘッド本体に導入された湯水の流れを切り換える構成を有したミスト発生装置が開示されている。具体的には、特許文献2のミスト発生装置は、ヘッド本体において、シャワー噴射部とミスト噴射部が背中合わせに設けられており、シャワーの噴射方向とミストの噴射方向が180度異なる位置関係とされた構成である。即ち、特許文献2では、シャワー用とミスト用の異なる構造の噴射部をそれぞれ備えている。   Therefore, in Patent Document 2, the shower injection part and the mist injection part are integrally formed in one shower head main body (hereinafter also referred to as the head main body) without using a nozzle member, and introduced into the head main body by the switching means. A mist generator having a configuration for switching the flow of the hot and cold water is disclosed. Specifically, in the mist generating device of Patent Document 2, the shower injection unit and the mist injection unit are provided back to back in the head body, and the shower injection direction and the mist injection direction are in a positional relationship different by 180 degrees. It is a configuration. That is, in patent document 2, the injection part of a different structure for showers and mist is provided, respectively.

しかしながら、特許文献2のミスト発生装置は、ミスト噴射部とシャワー噴射部のそれぞれに対して、専用の空間や部材を要し、さらに構造が繁雑となるため、製造コストが増加する問題がある。
また、使用時において、予期せぬ方向から湯水が噴射される場合があり、使用者に不快感を与える懸念があった。即ち、特許文献2では、湯水の温度を確認しようと一方の噴射部を下方に向けて噴射する際に、切換手段の切り換えが不十分であったり、切り換え状態の確認を怠ると、他方の噴射部から湯水が噴射して使用者が思いもよらず常温又は低温の水を浴びてしまう不具合があった。
However, the mist generating device of Patent Document 2 requires a dedicated space or member for each of the mist injection unit and the shower injection unit, and the structure becomes complicated, resulting in an increase in manufacturing cost.
In use, hot water may be ejected from an unexpected direction, which may cause discomfort to the user. That is, in Patent Document 2, when one of the injection units is injected downward to check the temperature of hot water, if the switching of the switching means is insufficient or the confirmation of the switching state is neglected, the other injection is performed. There was a problem that hot water was jetted from the part and the user unexpectedly bathed in water at normal or low temperature.

また、特許文献2のミスト発生装置は、シャワー噴射部とミスト噴射部が180度回転させた位置関係であるため、シャワー機能とミスト機能を連続的に使用する場合は、ヘッド本体を捻る必要があり、これに伴ってミスト発生装置に接続された湯水供給ホースも捻れ、その際に生じるホースの反力が使用者の負担となって使用感を損ねてしまう不満があった。   Moreover, since the mist generator of patent document 2 is the positional relationship which the shower injection part and the mist injection part rotated 180 degree | times, when using a shower function and a mist function continuously, it is necessary to twist a head main body. Along with this, the hot and cold water supply hose connected to the mist generating device is also twisted, and the reaction force of the hose generated at that time becomes a burden on the user and there is a complaint that the feeling of use is impaired.

そこで、本発明では、従来技術の問題に鑑み、製造コストを増加させることなく、シャワーヘッド本体にシャワー機能とミスト機能を一体的に備えることができると共に、使用者に不便を感じさせることがないミスト発生装置を提供することを目的とする。   Therefore, in the present invention, in view of the problems of the prior art, the shower head body can be provided with a shower function and a mist function integrally without increasing the manufacturing cost, and the user is not inconvenienced. It aims at providing a mist generator.

上記課題を解決するため、請求項1に記載の発明は、供給された湯水をミスト噴射又シャワー噴射可能なミスト発生装置であって、湯水を噴射する噴射部を有したフロント部材と、フロント部材と対となって外郭を形成し供給された湯水をフロント部材側に流すリア部材と、噴射部に対して近接・離反方向に移動して噴射部に導入される湯水の流路を第1経路又は第2経路に切り換える閉塞部材とを備え、フロント部材には、噴射部における湯水の流れ方向上流側の壁面から突出した凸部を複数有し、噴射部と第1経路と第2経路は、前記凸部の位置に設けられており、凸部の一部又は全部が連結されており、閉塞部材が噴射部から離反した状態となれば、供給された湯水は第1経路を介して直進的に流れて噴射部からシャワー噴射し、閉塞部材が噴射部に近接した状態となれば、供給された湯水は第2経路を介して旋回しながら流れて噴射部からミスト噴射することを特徴とするミスト発生装置である。 In order to solve the above-mentioned problem, the invention according to claim 1 is a mist generating device capable of mist injection or shower injection of supplied hot water, a front member having an injection portion for injecting hot water, and a front member The first member is a rear member that forms a shell in a pair and flows the hot water supplied to the front member side, and a flow path of hot water that is moved toward and away from the injection unit and introduced into the injection unit. Or a closing member that switches to the second path, and the front member has a plurality of protrusions protruding from the upstream wall surface in the flow direction of the hot water in the injection part, and the injection part, the first path, and the second path are: Provided at the position of the convex part, if part or all of the convex part is connected and the closing member is in a state separated from the injection part, the supplied hot water is straight through the first path. Flow into the shower and spray from the injection section If a state in which wood is close to the injection unit, hot water supplied is mist generating device, characterized in that the mist injected from the injection unit flows while swirling through the second path.

本発明のミスト発生装置は、フロント部材に設けられた噴射部に対して、閉塞部材を近接・離反方向に移動させて、噴射部に対する閉塞部材の位置によって、シャワー噴射とミスト噴射を切り換えることが可能な構成とされている。即ち、閉塞部材を噴射部に対して近接状態にしたり、噴射部から閉塞部材を離して両者の間隔を空けた状態にして、噴射部における湯水の流れ方(直進的又は旋回)を変更することで、シャワーとミストを切り換えることができる。従って、本発明によれば、簡単な構造でシャワー機能とミスト機能を一体的に備えた装置にできるため、製造コストの増加を招かない。   The mist generator of the present invention can switch between shower injection and mist injection depending on the position of the closing member relative to the injection unit by moving the closing member in the approaching / separating direction with respect to the injection unit provided on the front member. Possible configuration. That is, the closing member is brought into a close state with respect to the injection unit, or the closing member is separated from the injection unit and the both are spaced apart to change the flow of hot water (straight or swivel) in the injection unit. So you can switch between shower and mist. Therefore, according to the present invention, a device having a simple structure and a shower function and a mist function can be integrated, so that the manufacturing cost is not increased.

また、本発明によれば、同一の噴射部からシャワー噴射とミスト噴射を発生させることができる。これにより、シャワーとミストの切り換え状態に関わらず、シャワーの噴射方向やミストの噴射方向が変化することがないため、使用者が不快感を感じるという懸念がない。さらに、シャワーとミストを切り換えた際に、噴射部の向きを変える必要が無いため、「手首を捻る」必要がなく使用感が損なわれることもない。
従って、本発明によれば、製造コストを増加させることなく、シャワー機能とミスト機能を一体的に備えることができ、さらに使用者に不便を感じさせることがない。
Moreover, according to this invention, shower injection and mist injection can be generated from the same injection part. Thereby, regardless of the switching state between the shower and the mist, the shower injection direction and the mist injection direction do not change, so there is no concern that the user feels uncomfortable. Further, when the shower and the mist are switched, it is not necessary to change the direction of the injection unit, so that it is not necessary to “twist the wrist” and the feeling of use is not impaired.
Therefore, according to the present invention, the shower function and the mist function can be integrally provided without increasing the manufacturing cost, and the user is not inconvenienced.

フロント部材には、噴射部における湯水の流れ方向上流側の壁面から突出した凸部を有し、噴射部と第1経路と第2経路は、前記凸部の位置に設けられており、前記凸部に閉塞部材が当接すると、湯水は第2経路を介して噴射部に導入されるものであることが望ましい。 The front member has a protrusion protruding from the upstream wall surface in the hot water flow direction in the injection portion, and the injection portion, the first path, and the second path are provided at the position of the protrusion. When the closing member comes into contact with the part, it is desirable that the hot water is introduced into the injection part via the second path .

かかる構成によれば、フロント部材の壁面から突出した凸部の位置に噴射部と第1経路と第2経路が設けられているため、例えば、閉塞部材が複数の噴射部に近接した状態であっても、フロント部材と閉塞部材との間に凸部の突出長さ分の間隔が形成される。即ち、閉塞部材が凸部に当接した状態であっても、供給された湯水は、その間隔に流入し得るため、例えば、凸部の外側面に第2経路への導入口を設けた構成にすれば、その導入口から噴射部に対して湯水を導入することができる。   According to such a configuration, since the injection unit, the first path, and the second path are provided at the position of the convex portion protruding from the wall surface of the front member, for example, the closing member is in a state of being close to the plurality of injection units. However, an interval corresponding to the protruding length of the convex portion is formed between the front member and the closing member. That is, even when the closing member is in contact with the convex portion, the supplied hot water can flow into the gap, and thus, for example, a configuration in which an inlet to the second path is provided on the outer surface of the convex portion. If it does, hot water can be introduce | transduced with respect to an injection part from the inlet.

さらに、凸部における閉塞部材が当接する当接面に第1経路への導入口を設ければ、閉塞部材が凸部に当接した際にその導入口が閉鎖されるため、凸部に閉塞部材が当接した状態においては、噴射部には第2経路のみから湯水が導入される。
従って、本発明によれば、閉塞部材が当接する凸部の位置に噴射部と第1経路と第2経路を設けたため、シャワーとミストの切り換えを容易にできる。
Furthermore, if an introduction port to the first path is provided on the contact surface of the convex portion where the blocking member abuts, the introduction port is closed when the blocking member contacts the convex portion. In a state where the members are in contact with each other, hot water is introduced into the injection unit only from the second path.
Therefore, according to the present invention, since the injection part, the first path, and the second path are provided at the position of the convex part where the blocking member abuts, switching between the shower and the mist can be facilitated.

前記閉塞部材は、供給される湯水の水圧によって、噴射部に対して近接・離反することが望ましい。 It is desirable that the closing member be moved closer to or away from the injection unit by the water pressure of the supplied hot water .

かかる構成によれば、供給される湯水の水圧によって閉塞部材がフロント部材側に押圧されるため、複数の閉塞部材を備えた場合であっても、1つの部材であって複数の噴射部を閉塞できる程度の大きさの閉塞部材を備えた場合であっても、閉塞部材を均等且つ確実に十分な力で押圧できる。これにより、噴射部におけるシール性を確実に向上させることができるため、確実にミストを噴射させることができる。   According to such a configuration, since the closing member is pressed toward the front member side by the water pressure of the supplied hot water, even if a plurality of closing members are provided, a single member closes the plurality of injection portions. Even when a closing member having a size as large as possible is provided, the closing member can be pressed evenly and reliably with sufficient force. Thereby, since the sealing performance in an injection part can be improved reliably, mist can be injected reliably.

前記閉塞部材を噴射部に対して近接方向に付勢する弾性体を有することが望ましい。It is desirable to have an elastic body that urges the closing member in the proximity direction with respect to the injection portion.

かかる構成によれば、閉塞部材をバネなどの弾性体を用いてフロント部材側に付勢するため、噴射部におけるシール性を向上させることができるため、確実にミストを噴射させることができる。   According to this configuration, since the closing member is urged toward the front member using an elastic body such as a spring, the sealing performance in the injection section can be improved, so that mist can be reliably injected.

前記した請求項1に記載の発明は、フロント部材には、噴射部における湯水の流れ方向上流側の壁面から突出した凸部を複数有し、噴射部と第1経路と第2経路は、前記凸部の位置に設けられており、凸部の一部又は全部が連結されていることを特徴としている In the first aspect of the present invention, the front member has a plurality of protrusions protruding from the upstream wall surface in the flow direction of the hot water in the injection unit, and the injection unit, the first path, and the second path are It provided at a position of the convex portion, and wherein a portion of the convex portion or all are connected.

かかる構成によれば、フロント部材の壁面から突出した複数の凸部の一部又は全部が連結されているため、噴射部をより密集させて配置することができる。これにより、装置全体をコンパクト化しつつ、一定以上のミストの噴射量を確保することができる。なお、連結する凸部同士においては、噴射部、第1経路、及び第2経路が重なり合わないようにすることが望ましい。   According to this configuration, since some or all of the plurality of convex portions protruding from the wall surface of the front member are connected, the injection portions can be arranged more densely. As a result, it is possible to secure a certain amount of mist injection amount or more while making the entire apparatus compact. In addition, in the convex parts to connect, it is desirable to prevent the injection part, the first path, and the second path from overlapping each other.

請求項2に記載の発明は、供給された湯水をミスト噴射又シャワー噴射可能なミスト発生装置であって、湯水を噴射する噴射部を有したフロント部材と、フロント部材と対となって外郭を形成し供給された湯水をフロント部材側に流すリア部材と、噴射部に対して近接・離反方向に移動して噴射部に導入される湯水の流路を第1経路又は第2経路に切り換える閉塞部材とを備え、フロント部材は、噴射部を有した外殻部材と、前記外殻部材とリア部材との間に位置し外郭部材と湯水が流入する空間を形成する中間部材を備え、外殻部材と中間部材との間には閉塞部材が位置し、中間部材には、閉塞部材よりフロント部材側に湯水を供給するシャワー流路と、閉塞部材よりリア部材側に湯水を供給するミスト流路とが設けられており、閉塞部材が噴射部から離反した状態となれば、供給された湯水は第1経路を介して直進的に流れて噴射部からシャワー噴射し、閉塞部材が噴射部に近接した状態となれば、供給された湯水は第2経路を介して旋回しながら流れて噴射部からミスト噴射することを特徴とするミスト発生装置である。 The invention according to claim 2 is a mist generating device capable of mist injection or shower injection of supplied hot water, a front member having an injection portion for injecting hot water, and a front member paired with an outer shell. A rear member that flows the formed and supplied hot water to the front member side, and a block that switches the flow path of hot water introduced to the injection section to the first path or the second path by moving in a direction close to or away from the injection section And the front member includes an outer shell member having an injection portion, and an intermediate member that is located between the outer shell member and the rear member and forms a space into which the outer shell member and hot water flow. A blocking member is located between the member and the intermediate member, and the intermediate member includes a shower channel that supplies hot water from the blocking member to the front member side, and a mist channel that supplies hot water from the blocking member to the rear member side. Doo is provided, the closing member If it is in a state of being separated from the injection unit, the supplied hot water flows straight through the first path and is sprayed from the injection unit, and if the closing member is in the vicinity of the injection unit, the supplied hot water is supplied. Is a mist generating device characterized in that it flows while turning through a second path and mist is injected from the injection section .

かかる構成によれば、フロント部材における外郭部材と中間部材との間の空間に閉塞部材が配され、中間部材に設けられたシャワー流路により、湯水は閉塞部材とフロント部材との間に供給され、中間部材に設けられたミスト流路により、湯水は閉塞部材とリア部材との間に供給されるため、シャワー流路とミスト流路とを切り換えることで、閉塞部材を容易に移動させることができる。
即ち、シャワー流路から空間に湯水が供給されると、その湯水は外郭部材と閉塞部材との間(下流側空間)に流入するため、下流側空間の水圧が上昇して閉塞部材がその水圧により中間部材側に押される。これにより、閉塞部材が噴射部に対して離反する方向に移動するため、湯水は噴射部に対して直進的に流れてシャワー流が噴射される。一方、ミスト流路から空間に湯水が供給されると、その湯水は閉塞部材と中間部材との間(上流側空間)に流入するため、上流側空間の水圧が上昇して閉塞部材が水圧により外郭部材側に押される。これにより、閉塞部材が噴射部に対して近接する方向に移動するため、湯水は噴射部に対して旋回しながら流れてミスト流が噴射される。
従って、本発明によれば、シャワー流路とミスト流路のいずれかに切り換えて、閉塞部材に作用する水圧の作用方向を変化させることで、閉塞部材を噴射部に対して近接・離反方向に移動させることができるため、湯水を空間に供給することによって、確実にミスト流又はシャワー流を噴射することができる。
According to such a configuration, the closing member is arranged in the space between the outer member and the intermediate member in the front member, and hot water is supplied between the closing member and the front member by the shower flow path provided in the intermediate member. Since the hot water is supplied between the closing member and the rear member by the mist channel provided in the intermediate member, the closing member can be easily moved by switching between the shower channel and the mist channel. it can.
That is, when hot water is supplied to the space from the shower channel, the hot water flows between the outer member and the closing member (downstream space), so that the water pressure in the downstream space rises and the closing member Is pushed to the intermediate member side. Thereby, since the closing member moves in a direction away from the injection unit, the hot water flows straight to the injection unit and a shower flow is injected. On the other hand, when hot water is supplied to the space from the mist channel, the hot water flows between the closing member and the intermediate member (upstream space), so the water pressure in the upstream space rises and the blocking member is It is pushed to the outer member side. Accordingly, since the closing member moves in a direction approaching the injection unit, the hot water flows while turning with respect to the injection unit, and a mist flow is injected.
Therefore, according to the present invention, by switching to either the shower channel or the mist channel and changing the direction of action of the water pressure acting on the blocking member, the blocking member is moved closer to or away from the injection portion. Since it can be moved, a mist flow or a shower flow can be reliably jetted by supplying hot water to the space.

請求項に記載の発明は、フロント部材は、リア部材との重ね合わせ面に対して摺動回転可能であって、フロント部材を回転させた所定の位置においては、シャワー流路とミスト流路のうちの一方の流路が閉鎖されると共に他方の流路が開放されることを特徴とする請求項に記載のミスト発生装置である。 According to a third aspect of the present invention, the front member is slidably rotatable with respect to the overlapping surface with the rear member, and the shower channel and the mist channel are provided at a predetermined position where the front member is rotated. The mist generating device according to claim 2 , wherein one of the channels is closed and the other channel is opened.

かかる構成によれば、フロント部材をリア部材に対して相対的に摺動回転させることで、シャワー流路とミスト流路を切り換えることができるため、一旦切り換えた流路の固定性が高い。つまり、ボタン式等であれば、シャワーやミストの最中に、不意にボタンを操作してしまい、流路が切り替わってしまうという不具合が考えられるが、本発明では、フロント部材をリア部材に対して相対的に摺動回転させなければ、流路が切り替わることがないため、そのような不具合が起き得ない。   According to this configuration, since the shower channel and the mist channel can be switched by sliding and rotating the front member relative to the rear member, the fixed property of the channel once switched is high. In other words, in the case of a button type or the like, there is a problem that the button is unexpectedly operated during a shower or mist, and the flow path is switched, but in the present invention, the front member is attached to the rear member. If the relative rotation is not performed, the flow path will not be switched, and such a problem cannot occur.

ここで、閉塞部材を複数の噴射部に跨る程度の大きさとする場合、部品点数を減少させることができるため、製造及び組み立てが容易となる。しかしながら、閉塞部材に生じる成型ムラなどにより、全ての噴射部を均等に且つ確実にシールすることができなくなる場合が生じ得る。これにより、噴射部の一部において湯水が旋回することがなくなり、その噴射部からはミスト噴射を発生させることができなくなるという問題が発生していた。
そこで、請求項に記載の発明では、閉塞部材は、フロント部材及びリア部材と比較して軟質の合成樹脂又は弾性材であり、且つ複数の噴射部に跨って配される程度の大きさであることを特徴とする請求項1乃至3のいずれかに記載のミスト発生装置とした。
Here, in the case where the closing member has a size that spans the plurality of injection portions, the number of parts can be reduced, and thus manufacturing and assembly are facilitated. However, there may be a case where it becomes impossible to seal all of the injection portions uniformly and reliably due to molding unevenness generated in the closing member. As a result, there is a problem in that hot water does not swirl in a part of the injection unit, and mist injection cannot be generated from the injection unit.
Therefore, in the invention according to claim 4 , the closing member is a soft synthetic resin or an elastic material as compared with the front member and the rear member, and is large enough to be disposed across a plurality of injection portions. The mist generator according to any one of claims 1 to 3 , wherein the mist generator is provided.

かかる構成によれば、閉塞部材が複数の噴射部に跨って配される程度大きさであると共に、フロント部材及びリア部材よりも軟質の合成樹脂又は弾性材が採用されるため、成型ムラ等で閉塞部材に若干凹凸があったとしても、その凹凸の不具合を材質でカバーできる。即ち、成型ムラによって凹凸が形成された閉塞部材で、噴射部を覆った場合であっても、外力により閉塞部材が変形してシール性の不具合をカバーすることができる。これにより、1つの閉塞部材で複数の噴射部を覆った場合に、複数の噴射部のうちの一部からミスト噴射が発生しなくなるという不具合が発生することがない。   According to such a configuration, since the closing member is large enough to be disposed across the plurality of injection portions, and a softer synthetic resin or elastic material is employed than the front member and the rear member, Even if the closing member has some irregularities, the irregularities can be covered with the material. That is, even when the injection member is covered with a closing member having irregularities formed by molding unevenness, the closing member can be deformed by an external force to cover a sealing problem. Thereby, when one injection member covers a plurality of injection parts, the malfunction that mist injection does not occur from a part of a plurality of injection parts does not occur.

本発明のミスト発生装置では、フロント部材とリア部材との間に配置した閉塞部材を噴射部に対して近接・離反させてシャワー噴射とミスト噴射を切り換えることができるため、構造を簡易なものとすることができると共に、同一の噴射部からミスト噴射やシャワー噴射を発生させることができる。これにより、製造コストを増加させることなく、シャワー機能とミスト機能を一体的に備えることができ、さらに利便性を向上させることができる。   In the mist generating device of the present invention, the closing member disposed between the front member and the rear member can be moved close to and away from the injection portion to switch between shower injection and mist injection, so that the structure is simplified.

It is comprised by the holding member 13 which can hold | grip.

フロント部材7は、PPS(Polyphenylene sulfide )を含んだ合成樹脂を用いて成型されたもので、図3に示すように、噴射部15が設けられ装置の外郭の一部を形成する外郭部材35と、外郭部材35とリア部材8との間に位置し異なる2流路を備えた中間部材36とにより構成されている。   The front member 7 is molded using a synthetic resin containing PPS (Polyphenylene sulfide). As shown in FIG. 3, the front member 7 includes an outer member 35 provided with an injection portion 15 and forming a part of the outer shell of the apparatus. The intermediate member 36 is provided between the outer member 35 and the rear member 8 and has two different flow paths.

外郭部材35は、ほぼ円形の板状体であり、一方の壁面側が外郭部材35の厚み方向(他方の壁面側)に窪んだ外郭側凹部43が設けられている(以下、外郭側凹部43が設けられた壁面を有凹壁面と称す)。外郭側凹部43は、窪み形状がほぼ円柱状である。また、外郭側凹部43には、図2に示すように、外郭部材35の壁面であって凹部の底部から垂直方向に突出したほぼ円柱状の凸部14が複数(本実施形態では33個)設けられている。いずれの凸部14も、壁面からの突出長さが等しく形成されている。   The outer member 35 is a substantially circular plate-like body, and is provided with an outer side concave portion 43 in which one wall surface side is recessed in the thickness direction of the outer member 35 (the other wall surface side) (hereinafter, the outer side concave portion 43 is referred to as the outer side concave portion 43. The provided wall is called a concave wall). The outer side recess 43 has a substantially cylindrical shape. Further, as shown in FIG. 2, the outer side concave portion 43 includes a plurality of substantially cylindrical convex portions 14 which are the wall surfaces of the outer member 35 and protrude in the vertical direction from the bottom portion of the concave portion (33 in this embodiment). Is provided. All the convex portions 14 are formed to have the same protruding length from the wall surface.

凸部14には、単独で存在する独立凸部47が3個と、複数の凸部14が連結した連結凸部48が10組ある。本実施形態では、連結凸部48として、2つの凸部14が連結したものが2組と、3つの凸部14が連結したものが7組と、5つの凸部14が連結したものが1組ある。そして、これらの凸部14は、外郭部材35の中心には配置されず、密度が均等になるようにドーナツ状に配置されている。なお、この凸部14が配されない中心の面積は、後述するシャワー流路形成部51の下流側配管部51bの外径を基準とした面積程度とされている。   The convex portion 14 includes three independent convex portions 47 that exist independently, and ten connected convex portions 48 that are connected to the plurality of convex portions 14. In the present embodiment, as the connecting convex portion 48, two sets of two convex portions 14 connected, two sets of three convex portions 14 connected, and seven sets of five convex portions 14 connected are one. There are pairs. And these convex parts 14 are not arrange | positioned at the center of the outer shell member 35, but are arrange | positioned at donut shape so that a density may become equal. In addition, the area of the center where this convex part 14 is not distribute | arranged is made into the area extent on the basis of the outer diameter of the downstream piping part 51b of the shower flow path formation part 51 mentioned later.

また、凸部14の位置には、図4〜6に示すように、外郭側凹部43の窪み方向に延びた流路状の噴射部15と、噴射部15に湯水を供給する直進流路17と、直進流路17と連通した旋回流形成溝16が設けられている。   Further, as shown in FIGS. 4 to 6, at the position of the convex portion 14, as shown in FIGS. And a swirl flow forming groove 16 communicating with the straight flow path 17 is provided.

噴射部15は、図6に示すように、円錐状流路19と噴射流路18とが連通して形成されている。具体的には、有凹壁面側(一方の壁面側)に円錐状流路19が位置し、他方の壁面側(以下、吐出壁面側とも称す)に噴射流路18が位置する。即ち、円錐状流路19と噴射流路18は、外郭部材35の厚み方向中途で連通しており、双方の流路が外郭部材35における同一の壁面側に位置することはない。   As shown in FIG. 6, the injection unit 15 is formed by connecting a conical channel 19 and an injection channel 18. Specifically, the conical channel 19 is positioned on the concave wall surface side (one wall surface side), and the injection channel 18 is positioned on the other wall surface side (hereinafter also referred to as the discharge wall surface side). That is, the conical channel 19 and the injection channel 18 communicate with each other in the thickness direction of the outer member 35, and the both channels are not positioned on the same wall surface side of the outer member 35.

円錐状流路19は、上流側で後述する直進流路17と連通しており、外郭部材35の有凹壁面側から噴射流路18との連通部に向かってテーパー状に内径が狭くなる流路である。即ち、円錐状流路19は、湯水の流れ方向下流側に向かって次第に流量が制限されるため、流速が加速される箇所である。また、円錐状流路19においては、湯水を流路の軸線方向に交差するように流すことで(実際には流路断面の接線方向に流す)、湯水の旋回流を効率的に発生させることができる箇所である。なお、円錐状流路19は後述する直進流路17と噴射流路18との間に位置し、いずれの境界においても流路が連続しており、その境界部においては、円錐状流路19と直進流路17との内径の大きさと、円錐状流路19と噴射流路18との内径の大きさはほぼ等しい。   The conical channel 19 communicates with a straight channel 17 (to be described later) on the upstream side, and the inner diameter of the conical channel 19 decreases in a tapered manner from the concave wall surface side of the outer member 35 toward the communicating portion with the injection channel 18. Road. That is, the conical channel 19 is a portion where the flow rate is accelerated because the flow rate is gradually limited toward the downstream side in the flowing direction of the hot water. Further, in the conical channel 19, hot water can be efficiently generated by swirling the hot water so as to intersect the axial direction of the flow channel (actually, flowing in the tangential direction of the cross section of the flow channel). This is where you can The conical channel 19 is located between a straight flow channel 17 and an injection channel 18 which will be described later, and the channel is continuous at any boundary, and the conical channel 19 is formed at the boundary. The inner diameter of the straight flow path 17 and the inner diameter of the conical flow path 19 and the injection flow path 18 are substantially equal.

噴射流路18は、流路形状が円柱状であり、湯水の流れ方向のいずれの箇所においても流路断面の内径の大きさがほぼ等しい流路である。即ち、噴射流路18に導入された湯水は、流路抵抗を無視すれば、流速をほぼ等速にして下流側に流れる箇所である。また、前記したように、噴射流路18の内径は、円錐状流路19における最下流部の内径の大きさとほぼ同じである。   The injection flow path 18 is a flow path having a cylindrical shape, and the inner diameter of the flow path cross section is substantially equal at any location in the hot water flow direction. That is, the hot water introduced into the injection flow path 18 is a portion that flows to the downstream side at a substantially constant flow velocity if the flow resistance is ignored. Further, as described above, the inner diameter of the injection channel 18 is substantially the same as the inner diameter of the most downstream portion in the conical channel 19.

直進流路17は、外郭部材35の有凹壁面側(一方の壁面側)に位置し流路形状が円柱状の流路で、流路長さが凸部14の突出長さにほぼ等しい。即ち、直進流路17は、凸部14の天面を貫通した開口17aを流路始端とし、噴射部15に連通した境界を流路終端としている。即ち、開口17aを介して直進流路17を通過する経路(第1経路)は、湯水を真っ直ぐに噴射部15に対して流すことができる。なお、その内径の大きさは、噴射部15における円錐状流路19の最上流部の内径の大きさとほぼ同じであり、円錐状流路19の最下流で連通した噴射流路18の内径の大きさより大きい。   The straight flow path 17 is located on the concave wall surface side (one wall surface side) of the outer member 35 and the flow path shape is a cylindrical flow path, and the flow path length is substantially equal to the protruding length of the convex portion 14. That is, the straight flow path 17 has an opening 17a penetrating the top surface of the convex portion 14 as a flow path start end and a boundary communicating with the injection section 15 as a flow path end. That is, the path (first path) that passes through the straight flow path 17 through the opening 17 a can flow hot water straight to the injection unit 15. The size of the inner diameter is substantially the same as the inner diameter of the most upstream portion of the conical channel 19 in the injection section 15, and the inner diameter of the injection channel 18 communicating at the most downstream side of the conical channel 19. Greater than size.

旋回流形成溝16は、凸部14の天面側に開放された溝型流路であり、凸部14の外側面を貫通した始端側溝型開口(流路始端)16aと、直進流路17の内側面を貫通した終端側溝型開口(流路終端)16bを有している。そして、旋回流形成溝16は、流路方向が直進流路17の流路断面の接線方向に延びるように設けられている。   The swirl flow forming groove 16 is a groove-type flow channel opened to the top surface side of the convex portion 14, a start-end side groove-type opening (flow channel start end) 16 a penetrating the outer surface of the convex portion 14, and a straight flow channel 17. And a terminal-side groove-type opening (flow-path end) 16b penetrating the inner surface of the terminal. The swirl flow forming groove 16 is provided such that the flow path direction extends in the tangential direction of the flow path cross section of the straight flow path 17.

また、旋回流形成溝16は、1つの噴射部15に対して2本ずつ設けられている。そして、その2本の旋回流形成溝16は、直進流路17の流路断面に対する接線方向が維持されつつ、互いに平行であり、且つずれた位置関係に配されている。換言すると、2本の旋回流形成溝16は、直進流路17に導入した湯水を同じ方向に旋回させることができる位置関係である。これにより、各旋回流形成溝16から直進流路17に導入されて旋回する湯水が、互いに衝突し合うことがない。具体的には、いずれの終端側溝型開口16bを介して直進流路17に湯水が導入されたとしても、その湯水は直進流路17の内壁に沿って同一方向に旋回しながら噴射部15に流入される。即ち、旋回流形成溝16と直進流路17を通過する経路(第2経路)は、噴射部15に導入する湯水を旋回させることができる。   Further, two swirl flow forming grooves 16 are provided for each injection unit 15. The two swirl flow forming grooves 16 are arranged in parallel with each other and shifted in position while maintaining a tangential direction with respect to the cross section of the straight flow path 17. In other words, the two swirl flow forming grooves 16 have a positional relationship that allows the hot water introduced into the straight flow path 17 to swirl in the same direction. Thereby, the hot and cold water swirled introduced into the straight flow path 17 from each swirl flow forming groove 16 does not collide with each other. Specifically, even if hot water is introduced into the straight passage 17 through any of the terminal-side groove-shaped openings 16b, the hot water turns to the injection unit 15 while turning in the same direction along the inner wall of the straight passage 17. Inflow. That is, the path (second path) passing through the swirl flow forming groove 16 and the straight flow path 17 can swirl hot water introduced into the injection unit 15.

中間部材36は、図2、3に示すように、ほぼ円形のフランジ部50と、シャワー用流路形成部51と、ミスト用流路形成部52とを備えた部材である。
フランジ部50は、図3に示すように、一方の壁面側(以下、下流壁面側とも称す)に、外郭部材35の外郭側凹部43に嵌り込むリング状に突出したフロント側装着部53が設けられている。フロント側装着部53には、外周壁を沿うように図示しないリング状のゴムパッキンが装着される。即ち、フロント側装着部53の外径の大きさは、外郭側凹部43の内径の大きさより若干小さく形成されている。
As shown in FIGS. 2 and 3, the intermediate member 36 is a member provided with a substantially circular flange portion 50, a shower channel forming portion 51, and a mist channel forming portion 52.
As shown in FIG. 3, the flange portion 50 is provided with a front side mounting portion 53 protruding in a ring shape that fits into the outer side concave portion 43 of the outer member 35 on one wall surface side (hereinafter also referred to as a downstream wall surface side). It has been. A ring-shaped rubber packing (not shown) is attached to the front side attachment portion 53 along the outer peripheral wall. That is, the outer diameter of the front side mounting portion 53 is slightly smaller than the inner diameter of the outer side recess 43.

また、フロント側装着部53は、壁面からの突出長さが外郭部材35の外郭側凹部43の窪み深さとほぼ同じである。即ち、外郭側凹部43にフロント側装着部53が嵌り込んだ状態においては、フロント側装着部53の突端部が対向する壁面に当接する。具体的には、外郭側凹部43にフロント側装着部53が嵌り込んだ状態においては、フロント側装着部53の突端部は外郭側凹部43の底部の壁面に当接する。   Further, the front side mounting portion 53 has a protruding length from the wall surface substantially equal to the depth of the recess of the outer side concave portion 43 of the outer member 35. That is, in a state where the front side mounting portion 53 is fitted in the outer side recess 43, the protruding end portion of the front side mounting portion 53 comes into contact with the opposing wall surface. Specifically, in a state where the front side mounting portion 53 is fitted in the outer side concave portion 43, the protruding end portion of the front side mounting portion 53 contacts the wall surface of the bottom portion of the outer side concave portion 43.

また、フランジ部50には、図2に示すように、他方の壁面側(以下、上流壁面側とも称す)に、後述するリア部材8のリア側被装着部21に嵌り込むリング状に突出したリア側装着部20が設けられている。リア側装着部20にも、外周壁を沿うように図示しないリング状のゴムパッキンが装着されるため、リア側装着部20の外径の大きさがリア側被装着部21の内径の大きさより若干小さく形成されている。   Further, as shown in FIG. 2, the flange portion 50 protrudes in a ring shape that fits into the rear side mounted portion 21 of the rear member 8 described later, on the other wall surface side (hereinafter also referred to as the upstream wall surface side). A rear side mounting portion 20 is provided. Since a ring-shaped rubber packing (not shown) is attached to the rear side mounting part 20 along the outer peripheral wall, the outer diameter of the rear side mounting part 20 is larger than the inner diameter of the rear side mounting part 21. It is formed slightly smaller.

シャワー用流路形成部51は、フランジ部50のほぼ中心を厚み方向(上流壁面から下流壁面方向)に貫通し、フランジ部50における上流壁面と下流壁面の双方から配管が突出した流路である。即ち、シャワー用流路形成部51は、上流側配管部51aと、下流側配管部51bと、両者の間に位置し両者を連通させるシャワー用フランジ流路部(図示しない)を備えている。
上流側配管部51aは、フランジ部50の上流壁面から垂直に突出しており、配管の側壁を貫通した2つの導入口61と、突端面に流路内部まで貫通しないネジ等が螺合される雌ネジ部62と、突端面近傍の外側壁であって導入口61より突端面側の位置に図示しないリング状のゴムパッキンが装着される外周溝63が設けられている。

That is, the shower channel forming part 51 includes an upstream pipe part 51a, a downstream pipe part 51b, and a shower flange channel part (not shown) that is located between and communicates with both.
The upstream-side piping part 51a protrudes perpendicularly from the upstream wall surface of the flange part 50, and is a female to which two inlets 61 that penetrate the side wall of the pipe, and screws that do not penetrate to the inside of the flow path are screwed to the projecting end face. A screw portion 62 and an outer peripheral groove 63 in which a ring-shaped rubber packing (not shown) is mounted are provided on the outer wall near the projecting end surface and on the projecting end surface side from the introduction port 61.

導入口61は、湯水が導入される開口で、開口形状がほぼ円形であり、2つの開口とも同じ開口径を有している。また、一方の導入口61を、開口に対して内側垂直方向に覗くと、一方の導入口61の開口と他方の導入口61の開口がほぼ重なる位置関係である。即ち、導入口61の一方の開口は、他方の開口に対して、上流側配管部51aの外周方向に180度離れた位置に配されている。なお、導入口61の開口径は、後述するリア部材8のシャワー用貫通孔70の内径とほぼ同じ大きさにされている。

Further, when one introduction port 61 is viewed in the direction perpendicular to the inside with respect to the opening, the opening relationship of one introduction port 61 and the opening of the other introduction port 61 are substantially overlapped. That is, one opening of the introduction port 61 is arranged at a position 180 degrees away from the other opening in the outer peripheral direction of the upstream side piping portion 51a. In addition, the opening diameter of the introduction port 61 is made into the substantially same magnitude | size as the internal diameter of the shower through-hole 70 of the rear member 8 mentioned later.
The female screw portion 62 is located at the substantial center of the protruding end surface of the upstream side piping portion 51a, and is a portion that is connected to the rear member 8 (described later) using screws or the like.
The outer circumferential groove 63 is a groove formed in a ring shape, and has a depth such that a part of a rubber packing (not shown) protrudes slightly outside the outer circumferential surface of the upstream side piping portion 51a.

また、下流側配管部51bは、フランジ部50の下流壁面から垂直に突出しており、壁面からの突出長さがフロント側装着部53の突出長さよりも短く、突端面に湯水が排出される排出開口65が設けられている。
即ち、シャワー用流路形成部51に導入される湯水は、導入口61から上流側配管部51aに流入し、図示しないシャワー用フランジ流路部を介して下流側配管部51bに流れて排出開口65から排出される。

ミスト用流路形成部52は、2箇所あり、フランジ部50の厚み方向(上流壁面から下流壁面方向)に貫通し、フランジ部50の直径上であってシャワー用流路形成部51を挟むような位置に設けられている。具体的には、ミスト用流路形成部52は、シャワー用流路形成部51の導入口61に対して、90度ずれた位置に配されている。即ち、2箇所のミスト用流路形成部52を結んだ仮想線Lと、シャワー用流路形成部51の2つの導入口61を結んだ仮想線Mは、立体的に直交する関係である。   There are two mist flow path forming portions 52 that penetrate in the thickness direction of the flange portion 50 (from the upstream wall surface to the downstream wall surface direction) and are on the diameter of the flange portion 50 so as to sandwich the shower flow channel forming portion 51. It is provided at a position. Specifically, the mist channel forming part 52 is arranged at a position shifted by 90 degrees with respect to the inlet 61 of the shower channel forming part 51. That is, the imaginary line L connecting the two mist channel forming parts 52 and the imaginary line M connecting the two inlets 61 of the shower channel forming part 51 are in a three-dimensionally orthogonal relationship.

ミスト用流路形成部52は、上流壁面側の壁面から垂直方向に突出した突出流路部52aと、下流壁面側における中間部材36の厚み方向に円錐状に窪んだ窪み部52bと、両者の間に位置し両者を連通させるミスト用フランジ流路部(図示しない)とにより構成されている。   The mist flow path forming part 52 includes a protruding flow path part 52a that protrudes in the vertical direction from the wall surface on the upstream wall surface side, a hollow part 52b that is recessed conically in the thickness direction of the intermediate member 36 on the downstream wall surface side, It is comprised by the mist flange flow-path part (not shown) which is located in between and connects both.

The protruding flow path portion 52a is a pipe-shaped flow path, has a protruding length that is the same as the protruding length of the rear side mounting portion 20, and is provided with an introduction port 68 through which hot water is introduced into the protruding end portion. The size of the inner diameter of the introduction port 68 is substantially the same as the mist opening 67 and the opening shape of the rear member 8 described later.
The hollow portion 52b is a flow path whose inner diameter is increased in a tapered shape toward the downstream side (downstream wall surface side) in the hot water flow direction.
That is, hot water introduced into the mist channel forming part 52 flows into the projecting channel part 52a from the introduction port 68, and is discharged from the recessed part 52b via a mist flange channel part (not shown).

また、本実施形態では、突出流路部52aを囲繞するように突出保持部66が設けられている。突出保持部66は、突出流路部52aから一定間隔を空けて配されており、その間隔に図示しないリング状のゴムパッキンを配して保持する部分である。また、突出保持部66は、壁面からの突出長さが突出流路部52aの突出長さと同じ大きさにされている。なお、図示しないゴムパッキンは、突出保持部66と突出流路部52aの突端部よりも外側に若干突出させる必要があるため、突出保持部66と突出流路部52aとの間の深さがゴムパッキンの部材厚より小さくされている。   In the present embodiment, the protruding holding portion 66 is provided so as to surround the protruding flow path portion 52a. The protrusion holding portion 66 is a portion that is arranged at a certain interval from the protrusion flow passage portion 52a, and is a portion that holds and holds a ring-shaped rubber packing (not shown) at that interval. Further, the protruding holding portion 66 has a protruding length from the wall surface that is the same as the protruding length of the protruding flow path portion 52a. Note that the rubber packing (not shown) needs to protrude slightly outward from the protruding holding portion 66 and the protruding end portion of the protruding flow path portion 52a, and therefore the depth between the protruding holding portion 66 and the protruding flow path portion 52a is small. It is made smaller than the member thickness of the rubber packing.

リア部材8は、PPS(Polyphenylene sulfide )を含んだ合成樹脂を用いて成型されたもので、図2に示すように、フロント部材7とほぼ同じ大きさの円形体である。

The rear member 8 is molded using a synthetic resin containing PPS (Polyphenylene sulfide), and is a circular body having substantially the same size as the front member 7 as shown in FIG.
The rear member 8 is provided with a ring-shaped rear side mounted portion 21 protruding from a wall surface into which the rear side mounting portion 20 of the front member 7 is fitted on one wall surface side (hereinafter also referred to as a mounting wall surface side). A connecting portion 55 to be connected to a gripping member 13 described later is provided on the wall surface side (hereinafter also referred to as a connecting wall surface side), and further for a shower penetrating in the thickness direction of the rear member 8 (from the mounting wall surface side to the connecting wall surface side). A through hole 70 and a mist through hole 67 are provided.

リア側被装着部21は、内径の大きさがフロント部材7のリア側装着部20に図示しないゴムパッキンを装着した状態の外径の大きさと同じあるいは若干小さくされている。また、リア側被装着部21は、壁面からの突出長さがフロント部材7のリア側装着部20の突出長さとほぼ同じである。即ち、リア側被装着部21にリア側装着部20が嵌り込んだ状態においては、互いの突端部が対向する壁面に当接する。具体的には、リア側被装着部21にリア側装着部20が嵌り込んだ状態においては、リア側被装着部21の突端部は中間部材36の壁面に当接し、リア側装着部20の突端部はリア部材8の壁面に当接する。   The rear-side mounted portion 21 has an inner diameter that is the same as or slightly smaller than the outer diameter when a rubber packing (not shown) is mounted on the rear-side mounting portion 20 of the front member 7. The rear side mounted portion 21 has a protruding length from the wall surface that is substantially the same as the protruding length of the rear side mounted portion 20 of the front member 7. That is, in a state where the rear side mounting portion 20 is fitted into the rear side mounted portion 21, the protruding end portions abut against the opposing wall surfaces. Specifically, in a state where the rear side mounting portion 20 is fitted in the rear side mounting portion 21, the protruding end portion of the rear side mounting portion 21 abuts against the wall surface of the intermediate member 36, and the rear side mounting portion 20 The protruding end abuts against the wall surface of the rear member 8.

シャワー用貫通孔70及びミスト用貫通孔67は、流路断面が円形で、リア側被装着部21の内側領域内に配されている。そして、シャワー用貫通孔70がリア部材8の中心に位置し、ミスト用貫通孔67がシャワー用貫通孔70からずれた位置に配されている。具体的には、シャワー用貫通孔70は、図7、8に示すように、リア部材8とフロント部材7の中心を一致させた状態において、常に重なり合う位置関係である。一方、ミスト用貫通孔67は、図7、8に示すように、リア部材8とフロント部材7の中心を一致させた状態において、ミスト用流路形成部52と同じ円周上にあり、ミスト用貫通孔67とミスト用流路形成部材52を重ね合わせた際に双方の開口がほぼ重なり合う位置関係である。   The shower through-hole 70 and the mist through-hole 67 have a circular channel cross section and are arranged in the inner region of the rear-side mounted portion 21. The shower through hole 70 is located at the center of the rear member 8, and the mist through hole 67 is disposed at a position shifted from the shower through hole 70. Specifically, as shown in FIGS. 7 and 8, the shower through-hole 70 has a positional relationship that always overlaps in a state where the centers of the rear member 8 and the front member 7 coincide. On the other hand, as shown in FIGS. 7 and 8, the mist through hole 67 is on the same circumference as the mist flow path forming portion 52 in a state where the centers of the rear member 8 and the front member 7 are aligned. When the through hole 67 for mist and the flow path forming member 52 for mist are overlapped, the two openings substantially overlap each other.

シャワー用貫通孔70は、内径の大きさがシャワー用流路形成部51における上流側配管部51aの外径の大きさと同じあるいは若干大きくされており、上流側配管部51aが挿入される部分である。即ち、シャワー用貫通孔70は、上流側配管部51aを保持する保持部として機能し、シャワー用貫通孔70に挿入された上流側配管部51aに湯水が流れる。従って、シャワー用貫通孔70には、実質的に湯水の流れはない。
一方、ミスト用貫通孔67は、内径の大きさがミスト用流路形成部52における突出流路部52aの内径の大きさと同じあるいは若干大きくされている。
The shower through-hole 70 has an inner diameter that is the same as or slightly larger than the outer diameter of the upstream-side piping part 51a in the shower channel forming part 51, and is a part where the upstream-side piping part 51a is inserted. is there. That is, the shower through-hole 70 functions as a holding unit that holds the upstream-side piping part 51 a, and hot water flows into the upstream-side piping part 51 a inserted into the shower through-hole 70. Therefore, there is substantially no flow of hot water in the shower through hole 70.
On the other hand, the through hole 67 for mist has an inner diameter that is the same as or slightly larger than the inner diameter of the protruding flow path portion 52 a in the mist flow path forming section 52.

接続部55は、図2に示すように、リア部材8の接続壁面側からシャワー用貫通孔70とミスト用貫通孔67を覆い、双方の貫通孔に湯水を送ることができる共通流路74を備えた部分であり、共通流路74の上流側で後述する把持部材13を接続するものである。そのため、接続部55の上流側には、リア部材8の装着壁面側まで貫通したネジ孔72が設けられおり、このネジ孔72にネジ等の接続手段が挿通されて後述する把持部材13が確実に固定される。なお、このネジ孔72は、リア部材8上であってリア側被装着部21の外側の領域あたる箇所にある。   As shown in FIG. 2, the connecting portion 55 covers the shower through-hole 70 and the mist through-hole 67 from the connection wall surface side of the rear member 8, and has a common channel 74 that can send hot water to both through-holes. It is a part provided, and connects the gripping member 13 described later on the upstream side of the common flow path 74. Therefore, a screw hole 72 penetrating to the mounting wall surface side of the rear member 8 is provided on the upstream side of the connecting portion 55, and a connecting means such as a screw is inserted into the screw hole 72 so that the gripping member 13, which will be described later, is securely attached. Fixed to. The screw hole 72 is located on the rear member 8 and in a region corresponding to a region outside the rear-side mounted portion 21.

また、接続部55における下流側には、ネジ等の接続手段が挿通可能なネジ孔71が設けられている。具体的には、このネジ孔71は、シャワー用貫通孔70の中心にあたる箇所にある。即ち、シャワー用貫通孔70にシャワー用流路形成部51の上流側配管部51aを挿通して雌ネジ部62をネジ孔71に合わせた状態で、ネジ孔71にネジ等を挿通して、リア部材8に対してフロント部材7を保持することができる。本実施形態では、このネジ等を用いてフロント部材7を保持しつつも、フロント部材7をリア部材8に対して相対回転可能な構成としている。   Further, a screw hole 71 through which a connecting means such as a screw can be inserted is provided on the downstream side of the connecting portion 55. Specifically, the screw hole 71 is located at the center of the shower through hole 70. That is, in the state where the upstream pipe portion 51a of the shower channel forming portion 51 is inserted into the shower through hole 70 and the female screw portion 62 is aligned with the screw hole 71, a screw or the like is inserted into the screw hole 71, The front member 7 can be held with respect to the rear member 8. In the present embodiment, the front member 7 is configured to be rotatable relative to the rear member 8 while holding the front member 7 using these screws and the like.

閉塞部材9は、フロント部材7やリア部材8に使用された材質より軟質の合成樹脂やゴム等の弾性体が採用されている。閉塞部材9は、ほぼ円形の板体であって、フロント部材7における全ての噴射部15を覆うことができる程度の面積を有していると共に、閉塞部材9の中心に厚み方向に貫通した貫通孔56を有する。また、閉塞部材9の厚みは、中間部材36の下流側配管部51bの突出長さよりも小さい値である。即ち、閉塞部材9は、ほぼドーナツ形状の板体である。
貫通孔56は、開口径の大きさがフロント部材7における中間部材36の下流側配管部51bの外径の大きさとほぼ等しく、下流側配管部51bが挿通される。そして、閉塞部材9は、下流側配管51bの突出長さよりも小さい値の厚みを有しているため、下流側配管51bの突出長さの領域内で移動する。即ち、下流側配管51bは、閉塞部材9がフロント部材7における噴射部15に対して近接・離反する際のガイドとしての機能を果たす。
The closing member 9 is made of an elastic material such as a synthetic resin or rubber that is softer than the material used for the front member 7 and the rear member 8. The closing member 9 is a substantially circular plate, has an area that can cover all the injection parts 15 in the front member 7, and penetrates through the center of the closing member 9 in the thickness direction. A hole 56 is provided. Further, the thickness of the closing member 9 is a value smaller than the protruding length of the downstream side piping portion 51 b of the intermediate member 36. That is, the closing member 9 is a substantially donut-shaped plate.
The through hole 56 has an opening diameter substantially equal to the outer diameter of the downstream pipe portion 51b of the intermediate member 36 in the front member 7, and the downstream pipe portion 51b is inserted therethrough. And since the closure member 9 has the thickness of the value smaller than the protrusion length of the downstream piping 51b, it moves within the area | region of the protrusion length of the downstream piping 51b. That is, the downstream side pipe 51 b functions as a guide when the closing member 9 approaches and separates from the injection portion 15 in the front member 7.

把持部材13は、湯水を流す流路であると共に、浴室内に固定された保持具80に保持させたり、使用者が実際に握る部分で、リア部材8と湯水供給配管11とを繋ぐものである。即ち、把持部材13の下流側にはリア接続部75が設けられ、上流側に配管接続部76が設けられている。なお、リア接続部75には、リア部材8の貫通孔72に挿通されたネジ等が係合する溝状の被係合部77と、図示しないリング状のゴムパッキンが装着される外周溝79が設けられている。外周溝79は、被係合部77よりも下流側に位置する。   The gripping member 13 is a flow path for flowing hot water, and is held by a holder 80 fixed in the bathroom, or is a part that is actually gripped by the user, and connects the rear member 8 and the hot water supply pipe 11. is there. That is, the rear connection part 75 is provided on the downstream side of the gripping member 13, and the pipe connection part 76 is provided on the upstream side. The rear connection portion 75 has a groove-like engaged portion 77 with which a screw or the like inserted through the through hole 72 of the rear member 8 is engaged, and an outer peripheral groove 79 in which a ring-shaped rubber packing (not shown) is attached. Is provided. The outer circumferential groove 79 is located on the downstream side of the engaged portion 77.

次に、ミスト発生装置1の組み立て構造について説明する。
本実施形態のミスト発生装置1は、図1、2に示すように、把持部材13の配管接続部76が湯水供給配管11と接続されており、その把持部材13にリア部材8とフロント部材7が接続されて形成されている。具体的には、図9に示すように、リア部材8は、把持部材13のリア接続部75に接続部55が接続されている。この状態においては、図9に示すように、リア部材8のネジ孔72と、把持部材13の被係合部77の位置が一致しており、リア部材8の装着壁面側からネジ孔72に挿通されたネジが、被係合部77に係合されている。なお、把持部材13における外周溝79には、図示しないゴムパッキンが装着されており、そのゴムパッキンが把持部材13とリア部材8の接続部55によって挟持されている。
Next, the assembly structure of the mist generator 1 will be described.
As shown in FIGS. 1 and 2, in the mist generating apparatus 1 of the present embodiment, the pipe connecting portion 76 of the gripping member 13 is connected to the hot water supply pipe 11, and the rear member 8 and the front member 7 are connected to the gripping member 13. Are connected. Specifically, as shown in FIG. 9, the rear member 8 has a connection portion 55 connected to a rear connection portion 75 of the gripping member 13. In this state, as shown in FIG. 9, the screw hole 72 of the rear member 8 and the position of the engaged portion 77 of the gripping member 13 coincide with each other. The inserted screw is engaged with the engaged portion 77. A rubber packing (not shown) is attached to the outer peripheral groove 79 of the gripping member 13, and the rubber packing is sandwiched between the connection portions 55 of the gripping member 13 and the rear member 8.

また、リア部材8は、装着壁面側のリア側被装着部21にフロント部材7における中間部材36のリア側装着部20が、図示しないゴムパッキンを装着した状態で嵌め込まれている。これにより、リア側装着部20とリア部材8と中間部材36によって囲まれたリア側空間29(図10)が形成される。リア部材8のシャワー用貫通孔70には、中間部材36における上流側配管部51aが図示しないゴムパッキンを装着した状態で挿通されている。そして、上流側配管部51aにおける導入口61が、リア部材8の接続部55における共通流路74と連通し得る位置に配されている。具体的には、上流側配管51aは、シャワー用貫通孔70に対して相対的に回転可能に挿通されており、上流側配管部51aを配管の周方向に所定の位置まで回転させると、導入口61が共通流路74と連通することができる配置である。なお、2つの導入口61のうち、一方の導入口61が共通流路74と連通した状態となれば、同時に他方の導入口61が共通流路74と連通した状態となることはない。   Further, the rear member 8 is fitted in the rear side mounted portion 21 on the mounting wall surface side with the rear side mounting portion 20 of the intermediate member 36 in the front member 7 mounted with a rubber packing (not shown). Thereby, a rear side space 29 (FIG. 10) surrounded by the rear side mounting portion 20, the rear member 8 and the intermediate member 36 is formed. The upstream side piping portion 51a of the intermediate member 36 is inserted into the shower through-hole 70 of the rear member 8 with a rubber packing (not shown) attached. The introduction port 61 in the upstream pipe portion 51 a is disposed at a position where it can communicate with the common flow path 74 in the connection portion 55 of the rear member 8. Specifically, the upstream pipe 51a is inserted so as to be rotatable relative to the shower through-hole 70, and is introduced when the upstream pipe 51a is rotated to a predetermined position in the circumferential direction of the pipe. In this arrangement, the port 61 can communicate with the common flow path 74. If one of the two inlets 61 communicates with the common channel 74, the other inlet 61 does not communicate with the common channel 74 at the same time.

さらに、上流側配管部51aとシャワー用貫通孔70の軸線がほぼ一致しているとすれば、その軸線を中心に、リア部材8のミスト用貫通孔67と中間部材36のミスト用流路形成部52が同一の円周上に存在する。即ち、図7、8に示すように、ミスト用流路形成部52の位置は、前記軸線を中心に、中間部材36をリア部材8に対して摺動回転すれば、ミスト用貫通孔67に連通することができる配置である。なお、1つのミスト用貫通孔67(固定側の貫通孔)に対して、2つのミスト用流路形成部52(回転移動側の流路)があるため、一方のミスト用流路形成部52がミスト用貫通孔67と連通した状態となれば、同時に他方のミスト用流路形成部52がミスト用貫通孔67と連通した状態となることはない。
また、ミスト用流路形成部52の突出流路部52aと突出保持部66との間には、図示しないゴムパッキンが配されている。
Furthermore, if the upstream pipe portion 51a and the shower through hole 70 have substantially the same axis, the mist through hole 67 in the rear member 8 and the mist flow path in the intermediate member 36 are formed around the axis. The parts 52 exist on the same circumference. That is, as shown in FIGS. 7 and 8, the position of the mist flow path forming portion 52 is located in the mist through hole 67 if the intermediate member 36 is slidably rotated with respect to the rear member 8 around the axis. It is an arrangement that allows communication. Since one mist through hole 67 (fixed side through hole) has two mist flow path forming parts 52 (rotational movement side flow paths), one mist flow path forming part 52 is provided. Is in a state of communicating with the mist through hole 67, the other mist flow path forming portion 52 is not in a state of communicating with the mist through hole 67 at the same time.
Further, a rubber packing (not shown) is disposed between the protruding flow path portion 52 a of the mist flow path forming section 52 and the protruding holding portion 66.

そして、中間部材36には、下流壁面側において、外郭部材35が組み付けられている。即ち、外郭部材35の外郭側凹部43に対して、図示しないゴムパッキンが装着された状態の中間部材36のフロント側装着部53が嵌め込まれている。これにより、外郭部材35と中間部材36との間に湯水が流入するフロント側空間24が形成される。
また、中間部材36におけるシャワー用流路形成部51の排出開口65は、凸部14の天面より下流側に閉塞部材9の厚みより小さい間隔を空けた配置とされている。即ち、フロント側空間24においては、シャワー用流路形成部51の排出開口65は下流側に位置し、ミスト用流路形成部52の排出側は上流側に位置している。
The outer member 35 is assembled to the intermediate member 36 on the downstream wall surface side. That is, the front side mounting portion 53 of the intermediate member 36 in a state where a rubber packing (not shown) is mounted is fitted into the outer side concave portion 43 of the outer member 35. Thereby, a front side space 24 into which hot water flows is formed between the outer member 35 and the intermediate member 36.
In addition, the discharge opening 65 of the shower channel forming portion 51 in the intermediate member 36 is arranged at a distance smaller than the thickness of the closing member 9 on the downstream side of the top surface of the convex portion 14. That is, in the front side space 24, the discharge opening 65 of the shower flow path forming portion 51 is located on the downstream side, and the discharge side of the mist flow path forming portion 52 is located on the upstream side.

なお、本実施形態では、外郭部材35と中間部材36との組み付けに、外郭側凹部43にフロント側装着部53を嵌合させて組み付ける手段に加えて、外郭部材35の外郭側凹部43側の壁面であって外郭側凹部43より外側の領域に、厚み方向に貫通しないネジ孔(図示しない)を設け、中間部材36に前記ネジ孔に対応する位置に厚み方向に貫通したネジ孔(図示しない)を設け、双方のネジ孔の位置を合わせてネジ等で締め付ける手段が併用されている。   In the present embodiment, in addition to the means for fitting the front side mounting portion 53 to the outer side concave portion 43 and assembling the outer member 35 and the intermediate member 36, the outer member 35 and the intermediate member 36 are mounted on the outer side concave portion 43 side of the outer member 35. A screw hole (not shown) that does not penetrate in the thickness direction is provided in an area outside the outer wall side recess 43 on the wall surface, and a screw hole (not shown) that penetrates the intermediate member 36 in the thickness direction at a position corresponding to the screw hole. ), And means for matching the positions of both screw holes and tightening them with screws or the like is also used.

また、本実施形態では、外郭部材35と中間部材36との間に、閉塞部材9を配置させて、噴射部15に導入される湯水の流入方向を切り換えて、湯水をシャワー流又はミスト流として噴射させるノズル機能を作用させる構成が形成されている。
即ち、フロント側空間24において、閉塞部材9の貫通孔56に中間部材36の下流側配管部51bを配し、閉塞部材9が外郭部材35の凸部14と対向するように配置されている。具体的には、閉塞部材9は、中間部材36の下流壁面と外郭部材35の凸部14の突端面との間に位置する。
Further, in the present embodiment, the closing member 9 is disposed between the outer member 35 and the intermediate member 36 to switch the inflow direction of the hot water introduced into the injection unit 15 so that the hot water is used as a shower flow or a mist flow. The structure which makes the nozzle function to inject act is formed.
That is, in the front side space 24, the downstream side piping portion 51 b of the intermediate member 36 is arranged in the through hole 56 of the closing member 9, and the closing member 9 is arranged to face the convex portion 14 of the outer member 35. Specifically, the closing member 9 is located between the downstream wall surface of the intermediate member 36 and the protruding end surface of the convex portion 14 of the outer member 35.

次に、ミスト発生装置1の作用について説明する。
ミスト発生装置1は、使用者によって浴室10内の混合栓5が操作され、適温の湯水が湯水供給配管11から装置の内部に導入されると、フロント側空間24に対する流路の切り換え状態によって、各噴射部15における湯水の流入方向を切り換えてシャワー流又はミスト流として外部に噴射するものである。
Next, the operation of the mist generator 1 will be described.
When the mixing tap 5 in the bathroom 10 is operated by the user and hot water at an appropriate temperature is introduced into the apparatus from the hot water supply pipe 11 by the user, the mist generating device 1 is switched according to the switching state of the flow path with respect to the front side space 24. The inflow direction of hot water in each injection unit 15 is switched and injected to the outside as a shower flow or a mist flow.

まず、シャワー流を噴射する場合について説明する。
シャワー流を噴射部15から噴射させる場合、フロント部材7の上流側配管部51aにおける導入口61を、リア部材8の接続部55における共通流路74と連通させる必要がある。即ち、フロント部材7をリア部材8に対して相対的に摺動回転させて、図10に示すように、導入口61と共通流路74とが連通する位置にフロント部材7を調整する。本実施形態では、フロント部材7又はリア部材8のいずれかに、導入口61が共通流路74と連通状態の位置であることを表示する表示部(図示しない)が設けられている。
First, the case where a shower flow is injected will be described.
When the shower flow is jetted from the jetting section 15, the inlet 61 in the upstream pipe section 51 a of the front member 7 needs to communicate with the common flow path 74 in the connecting section 55 of the rear member 8. That is, the front member 7 is slid and rotated relative to the rear member 8 to adjust the front member 7 to a position where the introduction port 61 and the common flow path 74 communicate with each other as shown in FIG. In the present embodiment, a display unit (not shown) is provided on either the front member 7 or the rear member 8 to display that the introduction port 61 is in a position in communication with the common flow path 74.

そして、この状態で、湯水供給配管11から装置の内部に湯水が導入されると、その湯水は把持部材13を介して、リア部材8の接続部55に導入される。接続部55においては、共通流路74と中間部材36の導入口61が使用者によって連通状態とされているため、湯水はその導入口61からシャワー用流路形成部51に導入される。
なお、このとき、リア部材8のミスト用貫通孔67は、リア部材8と中間部材36の間に形成されたリア側空間29と連通した状態であるが、ミスト用流路形成部52の上流側はリア部材8の装着壁面によって閉鎖された状態となるため、リア側空間29に導入された湯水は噴射部15に向かって流れることはない。
In this state, when hot water is introduced into the apparatus from the hot water supply pipe 11, the hot water is introduced into the connection portion 55 of the rear member 8 through the grip member 13. In the connection part 55, the common flow path 74 and the introduction port 61 of the intermediate member 36 are in communication with each other, and hot water is introduced from the introduction port 61 into the shower flow path forming part 51.
At this time, the mist through hole 67 of the rear member 8 is in communication with the rear side space 29 formed between the rear member 8 and the intermediate member 36, but upstream of the mist flow path forming portion 52. Since the side is closed by the mounting wall surface of the rear member 8, the hot water introduced into the rear side space 29 does not flow toward the injection unit 15.

そして、シャワー用流路形成部51に導入された湯水は、外郭側凹部43の中心に向かって流れ、フロント側空間24に流入する。より詳細に説明すると、シャワー用流路形成部51は、下流側配管部51bの排出開口65が凸部14の近傍まで近接しているため、下流側配管部51bからフロント側空間24に吐出された湯水は、外郭部材35の壁面に衝突してフロント側空間24内に拡がるように流れる。これにより、フロント側空間24が水圧により高圧となり、閉塞部材9が水圧により移動する。即ち、閉塞部材9は、中間部材36側に移動し、中間部材36の下流壁面を押圧した状態となる。換言すると、閉塞部材9によって、ミスト用流路形成部52の下流側を閉鎖した状態となる。   Then, the hot and cold water introduced into the shower channel forming part 51 flows toward the center of the outer side recess 43 and flows into the front side space 24. More specifically, the shower channel forming portion 51 is discharged from the downstream piping portion 51b to the front side space 24 because the discharge opening 65 of the downstream piping portion 51b is close to the vicinity of the convex portion 14. The hot water flows so as to collide with the wall surface of the outer member 35 and spread in the front space 24. Thereby, the front side space 24 becomes high pressure by the water pressure, and the closing member 9 moves by the water pressure. That is, the closing member 9 moves to the intermediate member 36 side and presses the downstream wall surface of the intermediate member 36. In other words, the closing member 9 closes the downstream side of the mist flow path forming portion 52.

そのため、この状態におけるフロント側空間24に導入された湯水は、開口17aから直進流路17に導入される。即ち、第1経路から噴射部15に湯水が導入されるため、直進流路17において湯水は旋回することなく真っ直ぐに流れる。そして、噴射部15においても湯水の旋回流が発生することはないから、湯水はシャワー流として外部に噴射される。即ち、本実施形態では、リア部材8の共通流路74とフロント部材7における中間部材36の導入口61を連通させて、閉塞部材9を水圧により中間部材36の下流壁面側に移動させることで、噴射部15からシャワー流を噴射させることができる。   Therefore, the hot and cold water introduced into the front space 24 in this state is introduced into the straight flow path 17 from the opening 17a. That is, since hot water is introduced from the first path to the injection unit 15, the hot water flows straight in the straight passage 17 without turning. And since the whirling flow of hot water does not generate | occur | produce also in the injection part 15, hot water is injected outside as a shower flow. That is, in this embodiment, the common flow path 74 of the rear member 8 and the introduction port 61 of the intermediate member 36 in the front member 7 are communicated, and the closing member 9 is moved to the downstream wall surface side of the intermediate member 36 by water pressure. The shower flow can be ejected from the ejection unit 15.

続いて、ミスト流を噴射する場合について説明する。
ミスト流を噴射部15から噴射させる場合、フロント部材7の突出流路部52aを、リア部材8のミスト用貫通孔67と連通させる必要がある。即ち、フロント部材7をリア部材8に対して相対的に摺動回転させて、図11に示すように、突出流路部52aとミスト用貫通孔67とが連通する位置にフロント部材7を調整する。本実施形態では、フロント部材7又はリア部材8のいずれかに、突出流路部52aとミスト用貫通孔67とが連通状態の位置であることを前記した表示部(図示しない)によって表示する。
Then, the case where a mist flow is injected is demonstrated.
When the mist flow is ejected from the ejection part 15, the protruding flow path part 52 a of the front member 7 needs to communicate with the mist through hole 67 of the rear member 8. That is, the front member 7 is slid and rotated relative to the rear member 8 to adjust the front member 7 to a position where the projecting flow passage 52a and the mist through hole 67 communicate with each other as shown in FIG. To do. In the present embodiment, either the front member 7 or the rear member 8 displays that the protruding flow path portion 52a and the mist through-hole 67 are in a communicating state by the display unit (not shown).

そして、この状態で、湯水供給配管11からミスト発生装置の内部に湯水が導入されると、その湯水は把持部材13を介して、リア部材8の接続部55に導入される。接続部55においては、ミスト用貫通孔67とフロント部材7の突出流路部52aとが使用者によって連通状態にされているため、湯水は、共通流路74からミスト用貫通孔67を介してミスト用流路形成部52に導入される。
なお、このとき、中間部材36の導入口61の位置が、接続部55の共通流路74に対して、シャワー用流路形成部51の周方向に90度ずれた位置とされているため、共通流路74に流入した湯水が上流側配管部51aの導入口61に導入されることはない。
In this state, when hot water is introduced into the mist generating device from the hot water supply pipe 11, the hot water is introduced into the connection portion 55 of the rear member 8 through the gripping member 13. In the connecting portion 55, the mist through hole 67 and the protruding flow path portion 52 a of the front member 7 are in communication with each other by the user, so that hot water flows from the common flow path 74 through the mist through hole 67. It is introduced into the mist channel forming part 52.
At this time, the position of the introduction port 61 of the intermediate member 36 is shifted by 90 degrees in the circumferential direction of the shower channel forming part 51 with respect to the common channel 74 of the connection part 55. Hot water that has flowed into the common flow path 74 is not introduced into the inlet 61 of the upstream pipe portion 51a.

そして、ミスト用流路形成部52に導入された湯水は、フロント側空間24に流入する。より詳細に説明すると、ミスト用流路形成部52の排出側は、閉塞部材9の移動領域よりも下流側に位置するため、窪み部52bからフロント側空間24に吐出された湯水は、閉塞部材9の上流側の面に衝突してフロント側空間24内に拡がるように流れる。これにより、閉塞部材9は外郭部材35側に移動する。   Then, the hot water introduced into the mist flow path forming portion 52 flows into the front space 24. More specifically, since the discharge side of the mist flow path forming portion 52 is located on the downstream side of the moving region of the closing member 9, the hot water discharged from the recessed portion 52b to the front side space 24 is blocked by the closing member. 9 so as to collide with the upstream surface and expand into the front space 24. As a result, the closing member 9 moves to the outer member 35 side.

そして、閉塞部材9によって、外郭部材35に設けられた凸部14の天面が押圧された状態となる。換言すると、凸部14の天面に設けられた直進流路17の開口17aが閉鎖された状態となる。即ち、第1経路が閉鎖された状態となるため、フロント側空間24に導入された湯水は、凸部14に設けられた旋回流形成溝16から直進流路17(第2経路)に導入される。従って、直進流路17では湯水の旋回流が形成される。   Then, the top surface of the convex portion 14 provided on the outer member 35 is pressed by the closing member 9. In other words, the opening 17a of the straight passage 17 provided on the top surface of the convex portion 14 is closed. That is, since the first path is closed, the hot water introduced into the front side space 24 is introduced from the swirl flow forming groove 16 provided in the convex portion 14 into the straight flow path 17 (second path). The Accordingly, a swirling flow of hot water is formed in the straight passage 17.

そして、第2経路を介して噴射部15に導入されると、円錐状流路19において、徐々に旋回の範囲が狭くされながら吐出側に向かって進行するため、進行するにしたがってさらに旋回流の旋回速度が増す。そして、旋回速度が高速となった湯水が外部に吐出されると、旋回により生じた遠心力により拡散してミスト流が発生する。即ち、本実施形態では、リア部材8のミスト用貫通孔67とフロント部材7における中間部材36のミスト用流路形成部52を連通させて、閉塞部材9を水圧により凸部14の天面に当接させることで、第1経路が閉鎖されて噴射部15からミスト流を噴射させることができる。   And when it introduce | transduces into the injection part 15 via a 2nd path | route, in the conical flow path 19, since it advances toward the discharge side, the range of a rotation is narrowed gradually, as it progresses, a further swirl flow Increases turning speed. When hot water having a high turning speed is discharged to the outside, it is diffused by the centrifugal force generated by the turning to generate a mist flow. That is, in the present embodiment, the mist through hole 67 of the rear member 8 and the mist flow path forming portion 52 of the intermediate member 36 in the front member 7 are communicated, and the closing member 9 is brought into contact with the top surface of the convex portion 14 by water pressure. By abutting, the first path is closed and the mist flow can be ejected from the ejection unit 15.

本実施形態のミスト発生装置1によれば、フロント部材7をリア部材8に対して摺動回転させて、フロント側空間24に導入する湯水の流路を変更することができ、さらにフロント側空間24に導入された湯水の水圧によって閉塞部材9を噴射部15に対して近接・離反するように移動させて、噴射部15に導入する湯水の経路を切り換えることができる。これにより、同一の噴射部15からシャワー流とミスト流を噴射することができるため、従来技術のように、流路の切り換え状態によって、予期せぬ方向から湯水が噴射されることがない上、噴射流を切り換えた際に「手首を捻る」必要がないため、使用感を損ねることがない。また、噴射部を機能毎に用意する必要がないため、構造が単純なものとなり、結果的に製造コストを抑えることができる。従って、本発明のミスト発生装置1によれば、製造コストを増加させることなく、シャワー機能とミスト機能を一体的に備えることができると共に、使用者に不便を感じさせることがない。   According to the mist generator 1 of the present embodiment, the front member 7 can be slid and rotated with respect to the rear member 8 to change the flow path of hot water introduced into the front side space 24, and the front side space. The passage of hot water introduced into the injection unit 15 can be switched by moving the closing member 9 so as to approach or separate from the injection unit 15 by the water pressure of the hot water introduced into 24. Thereby, since the shower flow and the mist flow can be injected from the same injection unit 15, hot water is not injected from an unexpected direction depending on the switching state of the flow path as in the prior art. Since there is no need to “twist the wrist” when the jet flow is switched, the feeling of use is not impaired. Moreover, since it is not necessary to prepare an injection part for every function, a structure becomes simple and, as a result, manufacturing cost can be held down. Therefore, according to the mist generating device 1 of the present invention, the shower function and the mist function can be integrally provided without increasing the manufacturing cost, and the user is not inconvenienced.

上記実施形態では、閉塞部材9が水圧によって噴射部15に対して近接・離反する構成を示したが、本発明はこれに限定されず、例えば、図12に示すように、閉塞部材9と中間部材36との間にバネなどの弾性体87を配置させた構成であっても構わない。これにより、ミスト噴射の際に、閉塞部材9をより強く凸部14に当接させることができるため、シール性が向上し、ミスト流の噴射をより確実なものとすることができる。なお、弾性体87の付勢力は、シャワー噴射の際にフロント側空間24に生じる水圧により動き得る程度のものとする。これにより、閉塞部材9と外郭部材35との間に湯水が導入された際に、閉塞部材9は噴射部15に対して離反する方向に移動できるため、シャワー噴射を確実に発生させることができる。また、他の構成として、中間部材36に図示しない突入・退出機構を設け、シャワー時には突入・退出機構を突入状態として弾性体を強制的に外郭部材35側に移動させ、ミスト時には突入・退出機構を退出状態として弾性体の規制状態を解除するようなものであっても構わない。これにより、弾性体における閉塞部材9への付勢状態を変更することができる。   In the said embodiment, although the structure which the closure member 9 adjoins / separates with respect to the injection part 15 with water pressure was shown, this invention is not limited to this, For example, as shown in FIG. An elastic body 87 such as a spring may be disposed between the member 36 and the member 36. Thereby, in the case of mist injection, since the closure member 9 can be made to contact | abut to the convex part 14 more strongly, a sealing performance improves and it can make injection of a mist flow more reliable. The urging force of the elastic body 87 is such that it can be moved by the water pressure generated in the front side space 24 during shower injection. Thereby, when hot water is introduced between the closing member 9 and the outer member 35, the closing member 9 can move in a direction away from the injection unit 15, and thus shower injection can be reliably generated. . As another configuration, a rush / retreat mechanism (not shown) is provided in the intermediate member 36, and the elastic body is forcibly moved to the outer member 35 side in the rush state during the shower, and the rush / retreat mechanism is mist. It is also possible to cancel the restriction state of the elastic body with the exit state. Thereby, the urging | biasing state to the closure member 9 in an elastic body can be changed.

また、上記実施形態では、1つの閉塞部材9で全ての噴射部15を覆うことができる構成を示したが、本発明はこれに限定されず、例えば、複数の閉塞部材を用いて全ての噴射部15を覆う構成であっても構わない。例えば、凸部14毎に閉塞部材を配したり、独立凸部47や連結凸部48毎に閉塞部材を配した構成であっても構わない。   Moreover, in the said embodiment, although the structure which can cover all the injection parts 15 with the one obstruction | occlusion member 9 was shown, this invention is not limited to this, For example, all the injections using a several obstruction | occlusion member It may be configured to cover the portion 15. For example, a configuration in which a blocking member is provided for each convex portion 14 or a blocking member is provided for each independent convex portion 47 or connecting convex portion 48 may be employed.

上記実施形態では、フロント部材7に独立凸部47と連結凸部48を混合して配した構成を示したが、本発明ではこれに限定されず、独立凸部47のみや、連結凸部48のみを配した構成であっても構わない。なお、連結凸部48のみをフロント部材7に配する場合は、特に組み合わせの個数はこだわらない。   In the above-described embodiment, the configuration in which the independent convex portion 47 and the connecting convex portion 48 are mixed and arranged on the front member 7 is shown. It may be a configuration in which only In addition, when only the connection convex part 48 is arranged on the front member 7, the number of combinations is not particularly limited.

上記実施形態では、2本の旋回流形成溝16を設けた構成を示したが、本発明はこれに限定されず、図13に示すように、1本であっても、3本以上であっても構わない。特に、旋回流形成溝16を複数本設ける場合においては、噴射部15に導入される湯水の流れが同じ方向となるように設計する必要がある。   In the above embodiment, the configuration in which the two swirl flow forming grooves 16 are provided is shown. However, the present invention is not limited to this, and as shown in FIG. It doesn't matter. In particular, when a plurality of swirl flow forming grooves 16 are provided, it is necessary to design so that the flow of hot water introduced into the injection unit 15 is in the same direction.

上記実施形態では、フロント部材7とリア部材8と把持部材13の1セットのみで構成したミスト発生装置1を示したが、例えば、図14に示すように、フロント部材7とリア部材8の基本セット85を複数備え、その基本セット85を筐体86により保持されたような構成としたミスト発生装置83であっても構わない。これにより、シャワー流の噴射範囲やミスト流の噴射範囲を拡大することができる。   In the above embodiment, the mist generating device 1 configured by only one set of the front member 7, the rear member 8, and the gripping member 13 has been shown. For example, as illustrated in FIG. 14, the basics of the front member 7 and the rear member 8. The mist generator 83 may be configured such that a plurality of sets 85 are provided and the basic set 85 is held by the housing 86. Thereby, the injection range of a shower flow and the injection range of a mist flow can be expanded.

上記実施形態のミスト発生装置1は、浴室10内の混合栓5から延びた湯水供給配管11に接続された構成を示したが、混合栓5より湯水の流れ方向上流側で分岐させた配管に接続した構成であっても構わない。   Although the mist generating apparatus 1 of the said embodiment showed the structure connected to the hot water supply piping 11 extended from the mixing plug 5 in the bathroom 10, it was connected to the piping branched on the flow direction upstream side of the hot water from the mixing plug 5. A connected configuration may be used.
