Description

本発明は、給水給湯システムに係り、特に節水型の給水給湯システムに関する。   The present invention relates to a water supply and hot water supply system, and more particularly to a water-saving water supply and hot water supply system.

近年、地球温暖化対策の一層の推進を図るため、「エネルギーの使用の合理化に関する法律（省エネ法）」が改正され、またこの規程に基づき、新たな住宅の省エネルギー性能向上を促進する措置として「住宅事業建築主の判断の基準」の告示がなされた。
住宅における一次エネルギー消費量のうち、その多くを給湯設備の一次エネルギー消費量が占めている。従って、給湯設備の給湯負荷を低減することは住宅の省エネルギー性能に大きく寄与することが可能となる。 In recent years, the “Act on Rational Use of Energy (Energy Conservation Law)” has been amended to further promote global warming countermeasures. Notification of “Criteria for Judgment by Housing Business Builders” was made.
Of the primary energy consumption in houses, the primary energy consumption of hot water supply equipment accounts for the majority. Therefore, reducing the hot water supply load of the hot water supply facility can greatly contribute to the energy saving performance of the house.

そこで、このような省エネルギー化の一環として、無駄な水の使用をなくし、不要な消費量を削減するための工夫がなされている。たとえば、台所水栓や浴室シャワーなどで湯水を使用する際、使用時に湯水を出しっ放しにしたり、必要以上の流量で使用したりすると、水の消費量が増えるだけでなく、給湯のためのエネルギー消費量も大きく増大する。   Therefore, as part of such energy saving, contrivances have been made for eliminating unnecessary water consumption and reducing unnecessary consumption. For example, when using hot water in a kitchen faucet or bathroom shower, if the hot water is left unattended during use or if it is used at a flow rate higher than necessary, not only will water consumption increase, Energy consumption will also increase significantly.

台所水栓においては、節水のために吐水量を削減すると、吐水の勢いが低下するため、洗浄の作業性が低下する。このため、洗浄力を高めつつ使用水量を節減することが大きな課題となっている。
例えば、本出願人は、吐水部を介して洗面ボウルに至る吐水に微細気泡を含ませる微細気泡発生装置を設けた洗面化粧台（特許文献１）を提案している。
また、吐水されるシャワー水に微細気泡を含ませる微細気泡発生装置を設けたシャワー装置（特許文献２、３）を提案している。 In the kitchen faucet, if the amount of water discharged is reduced to save water, the momentum of the water discharged decreases, so that the workability of the cleaning decreases. For this reason, it is a big subject to reduce the amount of water used while improving the cleaning power.
For example, the present applicant has proposed a bathroom vanity (Patent Document 1) provided with a fine bubble generating device that includes fine bubbles in water discharged to a wash bowl through a water discharge portion.
Moreover, the shower apparatus (patent document 2, 3) which provided the fine bubble generator which makes a shower water discharged include a fine bubble is proposed.

しかしながら、特許文献１乃至３のいずれも、シャワーや泡沫金具を水栓カランの先端に設置する方式であるため、すべてのカランに対応させるのは困難である。
このように泡沫金具を水栓カランの先端に設置する方式では、水流が不安定であり、止水時に泡沫金具の先端にたまった空気が、再吐水時に水滴とともに吐き出され、飛び散ったりすることもある。
台所水栓は、流し台にとりつけられているため、水栓から出る水が周囲に飛び散ったりして、使用者が濡れないようにする必要がある。
本発明は前記実情に鑑みてなされたもので、安定で、洗浄力の高い給水を行うことで、吐水量の削減をはかり、節水による省エネを実現しつつも快適な使用が可能な給水給湯システムを提供することを目的とする。 However, since all of Patent Documents 1 to 3 are a system in which a shower or foam metal fitting is installed at the tip of the faucet caran, it is difficult to correspond to all the curans.
In this way, in the method of installing the foam metal fitting at the tip of the faucet caran, the water flow is unstable, and the air collected at the tip of the foam metal fitting at the time of water stoppage is discharged together with water droplets at the time of re-watering and may be scattered. is there.
Since the kitchen faucet is attached to the sink, it is necessary to prevent the water from the faucet from splashing around and getting the user wet.

以下本発明の実施の形態について図面を参照しつつ詳細に説明する。
(実施の形態１)
この給水給湯システム１００は、気泡を安定的に吐水に混入させ、体積流量を増加させるとともに、吐水の勢いを確保する節水機能を備えたもので、図１に概要図を示すように、市水Ｗを供給するための水道管（図示せず）に接続された家庭用給水管から、水栓カラン３０に至る給水給湯経路に、気泡混入機構部１０を具備したことを特徴とする。この水栓カラン３０から吐水された気泡を含む水は、流し台２００に、供給され使用される。
この気泡混入機構部１０は、図２にブロック図を示すように、気泡混入部１０Ｓと、逆流防止機構部１０Ｐとを具備している。図３はこの気泡混入機構部１０を示す概要図、図４は要部拡大断面図である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(Embodiment 1)
This water supply and hot water supply system 100 is provided with a water-saving function that stably mixes air bubbles into the water discharge, increases the volume flow rate, and secures the momentum of the water discharge. As shown in a schematic diagram in FIG. A bubble mixing mechanism 10 is provided in a hot water supply / hot water path from a domestic water supply pipe connected to a water pipe (not shown) for supplying W to a faucet currant 30. Water containing bubbles discharged from the faucet currant 30 is supplied to the sink 200 and used.
As shown in the block diagram of FIG. 2, the bubble mixing mechanism unit 10 includes a bubble mixing unit 10S and a backflow prevention mechanism unit 10P. FIG. 3 is a schematic view showing the bubble mixing mechanism unit 10, and FIG.

この気泡混入機構部１０は図３及び４に示すように、吸気口１０１を隔てて外管１０２の端縁が、内管１０３の端縁と重なり合うように構成され、この吸気口１０１から空気が流路に混入するように構成される。図４において、（ａ）は通水時の状態を示し、（ｂ）は止水時の状態を示す。すなわち、外壁に突起部１０４を設けた内管１０３と、内管１０３の外側を覆うとともに、突起部１０４を囲むように形成された鍔部１０５を有する外管１０２とを具備し、内管１０３の外壁が突起部１０４よりも下流側で、徐々に径小となるテーパ面１０７を有している。そしてこの鍔部１０５において、外管１０２と内管１０３との間から空気が流入可能に構成され、気泡混入部１０Ｓを構成している。   As shown in FIGS. 3 and 4, the bubble mixing mechanism 10 is configured such that the edge of the outer tube 102 overlaps the edge of the inner tube 103 with the air intake port 101 interposed therebetween, and air is supplied from the air intake port 101. It is comprised so that it may mix in a flow path. In FIG. 4, (a) shows the state at the time of water flow, and (b) shows the state at the time of water stoppage. That is, an inner tube 103 provided with a protruding portion 104 on the outer wall, and an outer tube 102 that covers the outside of the inner tube 103 and has a flange 105 formed so as to surround the protruding portion 104, are provided. The outer wall has a tapered surface 107 that gradually becomes smaller in diameter on the downstream side of the protrusion 104. The flange portion 105 is configured such that air can flow from between the outer tube 102 and the inner tube 103 to form a bubble mixing portion 10S.

また内管１０３に形成された突起部１０４には、逆流防止機構部１０Ｐが形成されている。外管１０２との係合部に、Ｏリング挿通用の環状溝１０８が設けられており、この環状溝１０８と外管の鍔部１０５の内壁面１０５Ｓとの間で、Ｏリング１０９を係止することで、逆流防止機構部１０Ｐを構成し、逆流防止機能を有している。
ここで、内管１０３の上流側から矢印Ａの方向に水が流れると径が徐々に縮小しているため、通水時には図４（ａ）に示すように、ベンチュリー効果により、負圧となる。そこで、外管１０２内部の圧力が低下し、内管が矢印Ａ方向に移動し、Ｏリング１０９が、外管の鍔部１０５の内壁面１０５Ｓと離れ、吸気口１０１から、空気が流入する。 In addition, a backflow prevention mechanism 10P is formed on the protrusion 104 formed on the inner tube 103. An annular groove 108 for inserting an O-ring is provided at an engaging portion with the outer tube 102, and the O-ring 109 is locked between the annular groove 108 and the inner wall surface 105S of the flange portion 105 of the outer tube. By doing so, the backflow prevention mechanism part 10P is comprised and it has a backflow prevention function.
Here, when water flows in the direction of arrow A from the upstream side of the inner pipe 103, the diameter is gradually reduced. Therefore, as shown in FIG. 4A, a negative pressure is generated due to the venturi effect when water flows. . Therefore, the pressure inside the outer pipe 102 decreases, the inner pipe moves in the direction of arrow A, the O-ring 109 moves away from the inner wall surface 105S of the flange portion 105 of the outer pipe, and air flows from the intake port 101.

一方、止水時には内管１０３および外管１０２内の内圧が上昇することにより、配管内体積を増加させるために内管１０３が矢印Ｂ方向に移動する。そしてＯリング挿通用の環状溝１０８と、外管の鍔部１０５の内壁面１０５Ｓとの間で、Ｏリング１０９を圧迫することで、逆流防止機構部１０Ｐを構成し、逆流防止機能を発揮している。   On the other hand, when the water stops, the internal pressure in the inner tube 103 and the outer tube 102 rises, so that the inner tube 103 moves in the direction of arrow B in order to increase the volume in the pipe. The O-ring 109 is pressed between the annular groove 108 for inserting the O-ring and the inner wall surface 105S of the flange portion 105 of the outer tube, thereby constituting the backflow prevention mechanism portion 10P and exhibiting the backflow prevention function. ing.

この構成によれば、流水中は、ベンチュリー効果により、径が徐々に小さくなる管内での負圧で外管と内管との間に隙間すなわち吸気口が開き、止水中は、配管内の内圧が上昇することにより、配管内体積を増加させるために内管が移動し、外管と内管との間の隙間すなわち吸気口が閉じる。このため、ローリングポンプ、ベーンポンプ、ロータリポンプ、リニアポンプ等の動力ポンプなどの外部エネルギーを使用することなく、気泡の混入と逆流防止がきわめて簡単な構成で実現される。   According to this configuration, the flowing water has a negative pressure in the pipe that gradually decreases in diameter due to the venturi effect, so that a gap, that is, an intake port is opened between the outer pipe and the inner pipe. Rises, the inner pipe moves to increase the volume in the pipe, and the gap between the outer pipe and the inner pipe, that is, the air inlet is closed. For this reason, mixing of bubbles and prevention of backflow can be realized with a very simple configuration without using external energy such as a power pump such as a rolling pump, a vane pump, a rotary pump, or a linear pump.

このように構造も簡単で、メンテナンスフリーであるため、低コスト化をはかることができる。また、給水給湯経路に気泡混入機構部を設けることにより、気泡を安定的に吐水に混入させ、体積流量を増加させるとともに、吐水の勢いを確保することができる。従って少ない流量で、洗浄力を高めることが可能となり、使用水量の低減と洗浄能力の向上とが可能となる。従って、省エネ対策には極めて有効な給湯給水システムを提供することが可能となる   Since the structure is simple and maintenance-free, the cost can be reduced. Further, by providing the bubble mixing mechanism in the water supply and hot water supply path, bubbles can be stably mixed into the water discharge, the volume flow rate can be increased, and the momentum of the water discharge can be ensured. Accordingly, the cleaning power can be increased with a small flow rate, and the amount of water used can be reduced and the cleaning performance can be improved. Therefore, it is possible to provide a hot water supply system that is extremely effective for energy saving measures.

The bubble diameter adjusting unit 21 is connected in the middle of the pipe, and includes a bubble diameter adjusting unit main body 211 and a mesh 212 that matches the inner diameter of the bubble diameter adjusting unit main body 211. By allowing water to pass through 211, the bubble diameters can be made uniform, and even when there is a distance between the bubble mixing mechanism and the faucet currant, a uniform bubble flow can be maintained.
Accordingly, it is possible to prevent such a problem that the mixed bubbles are united and a uniform bubble flow cannot be maintained.

（実施の形態４）
次に本発明の実施の形態４について説明する。
前記実施の形態３では、メッシュからなる気泡径調整部２１を用いたが、本実施の形態では、図９に示すように、径大部２１１ａ、２１１ｂとの間に径小部２１３を設け、急激に圧力変動や流速変動を発生させるとともに、泡を破泡させるため拡縮経路を設けたものである。この例でも気泡径調整部２１は、気泡混入機構部１０と水栓カラン３０との間に配置されている。

従って本実施の形態によっても混入した気泡が合一してしまい、均一な気泡流を維持することができなくなるような不都合を防止することができる。 (Embodiment 4)
Next, a fourth embodiment of the present invention will be described.
In the third embodiment, the bubble diameter adjusting unit 21 made of mesh is used. However, in the present embodiment, as shown in FIG. 9, the small diameter part 213 is provided between the large diameter parts 211a and 211b. While abruptly generating pressure fluctuations and flow velocity fluctuations, an expansion / contraction path is provided to break the bubbles. Also in this example, the bubble diameter adjusting unit 21 is disposed between the bubble mixing mechanism unit 10 and the faucet currant 30.
The bubble diameter adjusting unit 21 is connected in the middle of the pipe, and includes a bubble diameter adjusting unit main body 211 and a mesh 212 that matches the inner diameter of the bubble diameter adjusting unit main body 211. By allowing water to pass through 211, the bubble diameters can be made uniform, and even when there is a distance between the bubble mixing mechanism and the faucet currant, a uniform bubble flow can be maintained.
Accordingly, it is possible to prevent inconvenience that the mixed bubbles are united by this embodiment and the uniform bubble flow cannot be maintained.

なお、この気泡径調整部２１は、給水給湯経路の水栓カラン３０の直前に設けられるようにしてもよい。
この構成により、水栓カラン３０から吐水する直前に気泡径を調整しているため、所望の大きさの気泡を含んだ吐水を得ることができる。

With this configuration, since the bubble diameter is adjusted immediately before water is discharged from the faucet currant 30, water discharge including bubbles of a desired size can be obtained.
Since the bubble diameter is determined by the ratio of the diameters of the large diameter portions 211a and 211b and the small diameter portion 213 provided therebetween, a desired bubble diameter can be freely obtained by adjusting these.

（実施の形態５）
次に本発明の実施の形態５について説明する。
本実施の形態では、図１０に本発明の実施の形態５の給湯給水システムの概要図を示すように、気泡混入機構部１０は、流量調整部１１と、気泡混入部１０Ｓとを具備し、前記気泡混入部１０Ｓは、逆流防止機構部１０Ｐを介して空気供給部１４に接続されており、止水時に、吸気経路から水が逆流するのを防止することができるようにしたものである。 (Embodiment 5)
Next, a fifth embodiment of the present invention will be described.
In the present embodiment, as shown in a schematic diagram of a hot water supply system in Embodiment 5 of the present invention in FIG. 10, the bubble mixing mechanism unit 10 includes a flow rate adjusting unit 11 and a bubble mixing unit 10S. The bubble mixing unit 10S is connected to the air supply unit 14 via the backflow prevention mechanism unit 10P, and can prevent water from flowing back from the intake path when the water stops.

この給水給湯システムは図１１に要部拡大断面図を示すように、流量調整部１１が、徐徐に縮径される第１の通路Ｐ２と一定の流路径の第２の通路Ｐ３と徐々に径大となる第３の通路Ｐ４と一定の流路径の第４の通路Ｐ５とで構成され、これら第１乃至第４の通路の流路径の比で流量調整がなされる。
流量調整部１１では、これら第１乃至第４の通路Ｐ２、Ｐ３、Ｐ４、Ｐ５の径とテーパを調整することで、高精度に流量調整を行うことができる。
また、領域Ｐ１は、前記実施の形態１で図３及び図４を用いて示したものと同様の、気泡混入部１０Ｓ、逆流防止機構部１０Ｐを構成する。
この流量調整部１１は、内管１０３の上流側から矢印Ａの方向に水が流れると径が徐々に縮小しているため、通水時には、ベンチュリー効果により、負圧となる。そこで、外管１０２内部の圧力が低下し、内管が矢印Ａ方向に移動し、Ｏリング１０９が、外管の鍔部１０５の内壁面１０５Ｓと離れ、吸気口１０１から、空気が流入することで流量を調整している。 As shown in the enlarged cross-sectional view of the main part in FIG. 11, the water supply and hot water supply system includes a first passage P2 that is gradually reduced in diameter and a second passage P3 that has a constant passage diameter and a diameter that is gradually reduced. The third passage P4 is a large passage and the fourth passage P5 has a constant passage diameter. The flow rate is adjusted by the ratio of the passage diameters of the first to fourth passages.
The flow rate adjusting unit 11 can adjust the flow rate with high accuracy by adjusting the diameter and taper of the first to fourth passages P2, P3, P4, and P5.
In addition, the region P1 constitutes the bubble mixing part 10S and the backflow prevention mechanism part 10P similar to those shown in FIGS. 3 and 4 in the first embodiment.
Since the diameter of the flow rate adjusting unit 11 gradually decreases when water flows in the direction of the arrow A from the upstream side of the inner pipe 103, the flow rate adjusting unit 11 becomes negative pressure due to the venturi effect when water flows. Therefore, the pressure inside the outer pipe 102 decreases, the inner pipe moves in the direction of arrow A, the O-ring 109 moves away from the inner wall surface 105S of the flange 105 of the outer pipe, and air flows from the intake port 101. The flow rate is adjusted with.

一方、止水時には内管１０３および外管１０２内の内圧が上昇することにより、配管内体積を増加させるために内管１０３が矢印Ｂ方向に移動する。そしてＯリング挿通用の環状溝１０８と、外管の鍔部１０５の内壁面１０５Ｓとの間で、Ｏリング１０９を圧迫することで、逆流防止機構部１０Ｐを構成し、逆流防止機能を発揮する。図１１は止水時を示す図である。
ここで同一部材には同一符号を付し、詳細な説明は省略する。 On the other hand, when the water stops, the internal pressure in the inner tube 103 and the outer tube 102 rises, so that the inner tube 103 moves in the direction of arrow B in order to increase the volume in the pipe. The O-ring 109 is pressed between the annular groove 108 for inserting the O-ring and the inner wall surface 105S of the flange portion 105 of the outer tube, thereby constituting the backflow prevention mechanism portion 10P and exhibiting the backflow prevention function. . FIG. 11 is a diagram showing the time of water stoppage.
Here, the same members are denoted by the same reference numerals, and detailed description thereof is omitted.

（実施の形態６）
次に本発明の実施の形態６について説明する。
本実施の形態では、図１２に本発明の実施の形態６の給湯給水システムの概要図を示すように、実施の形態５の給水給湯システムにおいて、逆流防止機構部１０Ｐと前記気泡混入部１０Ｓとの間にポンプなどの加圧機構部１５を具備したものである。 (Embodiment 6)
Next, a sixth embodiment of the present invention will be described.
In the present embodiment, as shown in a schematic diagram of a hot water supply system of Embodiment 6 of the present invention in FIG. 12, in the hot water supply system of Embodiment 5, the backflow prevention mechanism unit 10P and the bubble mixing unit 10S A pressurizing mechanism 15 such as a pump is provided between the two.

この構成によれば、逆流防止機構部１０Ｐと前記気泡混入部１０Ｓとの間にポンプなどの加圧機構部１５を具備しているため、ベンチュリー方式による自吸方式に比べ、吸気効率の向上を図ることができる。その際、加圧機構部の動力を、配管を流れる吐水の流速から取り出すことで、外部エネルギーを不要とすることができる。   According to this configuration, since the pressurization mechanism 15 such as a pump is provided between the backflow prevention mechanism 10P and the bubble mixing part 10S, the intake efficiency can be improved compared to the self-priming method using the venturi method. Can be planned. In that case, external energy can be made unnecessary by taking out the motive power of a pressurization mechanism part from the flow velocity of the discharged water which flows through piping.

（実施の形態７）
次に本発明の実施の形態７について説明する。
本実施の形態では、図１３に本発明の実施の形態７の給湯給水システムの概要図を示すように、上記給水給湯システムにおいて、逆流防止機構部１０Ｐと前記気泡混入部１０Ｓとの間に吸気量調整機構部１６を具備したものを含む。
この構成によれば、逆流防止機構部１０Ｐと前記気泡混入部１０Ｓとの間に吸気量調整機構部１６を設けることで、ベンチュリー効果による吸気量を吸気量調整機構部１６で変動させ、脈動を発生させることができる。その際、吸気量調整機構部１６の開閉の動力を、配管を流れる吐水の流速から取り出すことで外部エネルギーを不要とすることができる。 (Embodiment 7)
Next, a seventh embodiment of the present invention will be described.
In the present embodiment, as shown in a schematic diagram of a hot water supply system of Embodiment 7 of the present invention in FIG. 13, in the water supply hot water system, intake air is introduced between the backflow prevention mechanism unit 10P and the bubble mixing unit 10S. Including those equipped with the quantity adjusting mechanism 16.
According to this configuration, by providing the intake air amount adjustment mechanism unit 16 between the backflow prevention mechanism unit 10P and the bubble mixing unit 10S, the intake air amount adjustment mechanism unit 16 varies the intake air amount due to the venturi effect, and pulsation is caused. Can be generated. In that case, external energy can be made unnecessary by taking out the opening / closing power of the intake air amount adjusting mechanism 16 from the flow rate of the discharged water flowing through the pipe.

（実施の形態８）
次に本発明の実施の形態８について説明する。
本実施の形態では、図１４に本発明の実施の形態８の給湯給水システムの概要図を示すように、気泡回収部２０が、前記水栓カラン３０直前の前記水栓カラン３０よりも高い位置に空気貯留部４０を具備したものである。これは図１５に断面概要図を示すように水栓カラン直前の最も高い位置に空気貯留部４０を設置し、止水時に配管に残った空気を貯留している。この空気貯留部４０は鍔部１０５に設けられた空気孔４２と、逃げ孔４３とを有する空気溜本体４１とで構成される。 (Embodiment 8)
Next, an eighth embodiment of the present invention will be described.
In the present embodiment, as shown in a schematic diagram of the hot water supply system in Embodiment 8 of the present invention in FIG. 14, the bubble recovery unit 20 is positioned higher than the faucet currant 30 immediately before the faucet currant 30. The air storage unit 40 is provided. As shown in the schematic cross-sectional view of FIG. 15, an air storage unit 40 is installed at the highest position immediately before the faucet carran, and air remaining in the pipe at the time of water stoppage is stored. The air reservoir 40 includes an air reservoir body 41 having an air hole 42 provided in the flange 105 and an escape hole 43.

この構成によれば、この空気貯留部４０の空気溜本体４１の容量は気泡混入部１０Ｓで混入する気泡混入率と配管経路の径と長さとから設定するのが望ましい。この空気貯留部４０に貯留された空気は、次回吐水時に、気泡混入部１０Ｓを通る吐水により発生する負圧を利用し、空気貯留部４０と気泡混入部１０Ｓとを接続する配管を通り、再度吐水中に気泡として混入する。特に気泡混入部１０Ｓを図１１に通路Ｐ２−Ｐ５で示すように、ベンチュリー管構造とすることで、貯留された空気を効果的に吐水に混入することができる。ここでも、これら気泡回収部や気体混入機構部は水栓カランの近傍ではなく、少なくとも水栓カランから１ｍ〜２ｍあるいはそれ以上離間した位置に設けることで、安定した気泡混入が可能となる。   According to this configuration, it is desirable that the capacity of the air reservoir main body 41 of the air reservoir 40 is set based on the bubble mixing rate mixed in the bubble mixing unit 10S and the diameter and length of the piping path. The air stored in the air storage unit 40 uses the negative pressure generated by the water discharged through the bubble mixing unit 10S at the next water discharge, passes through the pipe connecting the air storage unit 40 and the bubble mixing unit 10S, and again Mix as bubbles in the water. In particular, as shown in the passage P2-P5 in FIG. 11, the bubble mixing portion 10S has a Venturi tube structure, so that the stored air can be mixed into the water discharge effectively. Also here, the bubble collecting section and the gas mixing mechanism section are provided not at the vicinity of the faucet carran but at least at a position 1 m to 2 m or more away from the faucet calan, so that stable air bubble mixing is possible.

（実施の形態９）
次に本発明の実施の形態９について説明する。
本実施の形態では、図１６に本発明の実施の形態９の給湯給水システムの概要図を示すように、給水給湯システムにおいて、さらに脈動発生機構部１８を具備したことを特徴とする。
この構成によれば、水栓カランの上流に、洗浄性向上のために流量を変動させるための脈動発生機構部１８例えば流量変動部を設置するようにしているため、節水のために吐水量を削減しても、吐水の勢いを低下させることなく、洗浄作業の作業性を向上することができる。ここで脈動発生機構部１８は、図１７に示すように、給水配管に流量調整部１１と流量変動部１９を設けることで構成される。この構成によれば、流量変動部１９により流量を変動させることができる。 (Embodiment 9)
Next, a ninth embodiment of the present invention will be described.
In the present embodiment, as shown in a schematic diagram of a hot water supply system in Embodiment 9 of the present invention in FIG. 16, the water supply hot water supply system further includes a pulsation generating mechanism section 18.
According to this configuration, since the pulsation generating mechanism 18 for changing the flow rate for improving the cleaning property, for example, the flow rate changing unit, is installed upstream of the faucet currant, Even if it reduces, the workability | operativity of a washing | cleaning operation | work can be improved, without reducing the momentum of water discharge. Here, as shown in FIG. 17, the pulsation generating mechanism unit 18 is configured by providing a flow rate adjusting unit 11 and a flow rate varying unit 19 in a water supply pipe. According to this configuration, the flow rate can be varied by the flow rate variation unit 19.

流量変動部１９は、タイマーにより所定の間隔で開閉する電磁弁を用いた経路の開閉や、キャビテーションによる振動を共振により増幅するなどの方法により、流量を変化させることができる。ここで弁は経路を完全に閉じることなく流量を絞る程度の弁でもよい。   The flow rate changing unit 19 can change the flow rate by a method such as opening / closing a path using an electromagnetic valve that opens and closes at a predetermined interval by a timer, and amplifying vibration due to cavitation by resonance. Here, the valve may be a valve that restricts the flow rate without completely closing the path.

さらにまたキャビテーションを使用することで、動力は不要であり、高周波数での脈動を発生することができる。キャビテーションは、液体の流れの中で圧力がごく短時間だけ（水では大気圧の1/50程度の）飽和蒸気圧より低くなったとき、液体中に存在する100ミクロン以下のごく微小な「気泡核」を核として液体が沸騰したり溶存気体の遊離によって小さな気泡が多数生じる現象である。圧力が変化すると沸騰していた気体の体積も変化し泡の大きさが変る。膨張と収縮を繰り返しながら圧力に応じてしだいに小さくなってゆく。小さくなる過程で、プロペラのような硬い表面近くの泡は粘性と表面張力も作用して、その表面に張り付きながら泡の遠い側がくぼみ、ジェットの勢いで表面に激突して泡は***する。
そして、最終的には周囲の圧力が飽和蒸気圧より高くなり、周囲の液体は泡の中心に向かって殺到して、気泡が消滅する瞬間に中心で衝突するため微小ながら強い圧力波が発生し、騒音・振動を発生させる。
水中でのキャビテーションの作る３０ミクロン前後の微小な泡は、５０キロヘルツ以上の高周波水中振動波（水中音波）を高い効率で減衰するといわれている。
このようなキャビテーションを用いることで、外部エネルギーを使用することなく、微細な気泡を高精度に混入させることができる。 Furthermore, by using cavitation, no power is required and pulsation at a high frequency can be generated. Cavitation is a very small “bubble” of 100 microns or less that exists in a liquid when the pressure is lower than the saturated vapor pressure for a very short time (about 1/50 of atmospheric pressure in water) in the liquid flow. This is a phenomenon in which a large number of small bubbles are generated by boiling a liquid or releasing dissolved gas with the nucleus as a nucleus. When the pressure changes, the volume of the boiled gas also changes and the bubble size changes. It gradually decreases according to pressure while repeating expansion and contraction. In the process of shrinking, bubbles near a hard surface such as a propeller are also affected by viscosity and surface tension. While sticking to the surface, the far side of the bubbles dents, crashing into the surface with the force of a jet, and the bubbles break up.
Eventually, the ambient pressure becomes higher than the saturated vapor pressure, and the surrounding liquid rushes toward the center of the bubble and collides at the center when the bubble disappears, generating a small but strong pressure wave. Generate noise and vibration.
It is said that microbubbles of about 30 microns created by cavitation in water attenuate high-frequency underwater vibration waves (underwater sound waves) of 50 kHz or more with high efficiency.
By using such cavitation, fine bubbles can be mixed with high accuracy without using external energy.

ここで、脈動発生機構は、気泡混入機構部と併用してもよいし、単体で使用してもよい。併用することにより、より少ない流量で洗浄力を上げることができる。ここでは、水栓カランの上流に、洗浄性向上のために流量を変動させるための脈動発生機構部例えば流量変動部を設置するようにしているため、節水のために吐水量を削減しても、吐水の勢いを低下させることなく、洗浄作業の作業性を向上することができる。給水配管に流量調整部と流量変動部を設け、流量変動部により流量を変動させることができる。   Here, the pulsation generating mechanism may be used together with the bubble mixing mechanism unit or may be used alone. By using in combination, the cleaning power can be increased with a smaller flow rate. Here, a pulsation generating mechanism, for example, a flow rate fluctuation unit, is provided upstream of the faucet carran to change the flow rate in order to improve cleanability. The workability of the cleaning operation can be improved without reducing the momentum of the water discharge. A flow rate adjustment unit and a flow rate variation unit are provided in the water supply pipe, and the flow rate can be varied by the flow rate variation unit.

なお、以上説明してきた実施の形態では、水栓カランよりも上流側に気泡混入機構部を設けたものであるが、さらに、上記構成に加えて、水栓カランにも、気泡発生装置を加えるようにしてもよい。   In the embodiment described above, the bubble mixing mechanism is provided on the upstream side of the faucet culan. In addition to the above configuration, a bubble generator is also added to the faucet culant. You may do it.

たとえば、水や温水が給水される給水管の先端をシャワーヘッドに接続し、給水管を介してシャワーヘッドに供給された水をシャワーヘッドのシャワー吐出孔からシャワー水として外部に吐水可能にし、このシャワー水に０．１〜１０００μｍの微細気泡を含有させる微細気泡発生装置を設けてもよい。詳しくは、シャワーヘッドに供給される水の給水経路は、湯沸かし機のような湯供給部から至る湯供給管と水道管のような水道水供給部から至る水供給管とが湯水混合弁の入口に接続され、この湯水混合弁の出口にシャワーヘッドに至る給水路が接続され、この給水路に吐水水量を制御する電磁弁で構成された給水流量弁が配設されると共に微細気泡発生装置が配設されている。   For example, the tip of a water supply pipe to which water or hot water is supplied is connected to the shower head, and water supplied to the shower head through the water supply pipe can be discharged outside as shower water from the shower discharge hole of the shower head. You may provide the microbubble generator which makes a shower water contain 0.1-1000 micrometers microbubble. In detail, the water supply path of the water supplied to the shower head includes a hot water supply pipe extending from a hot water supply section such as a water heater and a water supply pipe extending from a tap water supply section such as a water pipe to the inlet of the hot water mixing valve. A water supply passage leading to the shower head is connected to the outlet of the hot water mixing valve, a water supply flow rate valve composed of an electromagnetic valve for controlling the amount of discharged water is disposed in the water supply passage, and a fine bubble generator is provided. It is arranged.

ここで、気泡混入部にはエアポンプにより気体を水に圧送する強制混入機構を採用することも可能であるが、本実施の形態では、特に動力を必要としないために構成の簡略化を図り得る、給水路を流れる水に気体をエゼクター効果にて自然に引き込ませるエゼクター機構が採用されている。詳しくは、給水路に絞り部を設ける等して形成した負圧発生部に室内に開口する気体供給流路を接続することで構成され、室内の空気を水に混入可能にしている。ここで、気体供給流路には水の逆流を防ぐ逆止弁を設けるのが望ましい。   Here, it is possible to adopt a forced mixing mechanism that pumps gas to water by an air pump in the bubble mixing section. However, in this embodiment, since no power is required, the configuration can be simplified. An ejector mechanism that naturally draws gas into the water flowing through the water supply channel using the ejector effect is adopted. Specifically, it is configured by connecting a gas supply flow path that opens into the room to a negative pressure generating part formed by providing a throttling part in the water supply channel, etc., so that indoor air can be mixed into water. Here, it is desirable to provide a check valve for preventing the backflow of water in the gas supply channel.

さらにまた、気泡混入機構部としては、超高分子量ポリエチレンやポリプロピレンなどの略球形粒子を充填して加熱成型して形成した多孔体を用いたものも有効である。たとえば複数の流路に多孔体を配置するとともに、空気ポンプから空気用ホースを通して供給された空気を空気流路から各々の多孔体に供給し、空気流路から供給された空気を気泡混入部から外部へ逃がすこと無く、多孔体にすべて供給するよう工夫されている。   Furthermore, as the bubble mixing mechanism part, it is also effective to use a porous body formed by filling approximately spherical particles such as ultra-high molecular weight polyethylene or polypropylene and heat-molding. For example, a porous body is disposed in a plurality of flow paths, air supplied from an air pump through an air hose is supplied to each porous body from the air flow path, and air supplied from the air flow path is supplied from a bubble mixing unit. It is devised to supply all of the porous material without escaping to the outside.

気泡混入部に達した水流は気泡混入部の複数の多孔体に分割導入され、空気供給手段としての空気ポンプから供給された空気は空気流路を通して多孔体にて気泡として微細化され、水中に混入する。微細気泡を含む複数の水流は、メッシュにて一本の整流とするとともに、微細気泡を大径化させ、整流中に均一に分散させる。   The water flow that has reached the bubble mixing section is divided and introduced into a plurality of porous bodies in the bubble mixing section, and the air supplied from the air pump as the air supply means is refined as bubbles in the porous body through the air flow path, and into the water. Mixed. A plurality of water streams containing fine bubbles are rectified by a mesh, and the diameter of the fine bubbles is increased and dispersed uniformly during rectification.

そして、多孔体の水に接する面には、多数の独立開孔が設けられており、水のせん断力により気泡を微細化する。多孔体は通水路の一部をなしており、通水路壁面全周に設けられ、通水路方向に延長して設けられているため、流れの乱れやよどみを発生させることなく、開孔面積を大きくすることができる。また開孔面積を大きくすることで開孔部における気泡発生密度を低くすることができるため、大量の空気を混入させても気泡生成時の気泡合一が発生しにくく微細な独立気泡を生成することができる。このようにして、空気の圧力による運動量を確実に、効率よく、迅速に水に伝達することができる。また微細な気泡は剛性が高く変形しにくく、不要な運動を生じないため、でエネルギー損失は少ない。   And the surface which contacts the water of a porous body is provided with many independent aperture | openings, and a bubble is refined | miniaturized by the shearing force of water. The porous body forms part of the water channel, and is provided around the wall surface of the water channel and extended in the direction of the water channel, so that the pore area can be reduced without causing flow disturbance or stagnation. Can be bigger. In addition, since the bubble generation density in the opening can be lowered by increasing the opening area, even if a large amount of air is mixed, it is difficult for bubbles to coalesce during bubble generation, and fine closed cells are generated. be able to. In this way, the momentum due to the air pressure can be reliably and efficiently transmitted to the water. In addition, since the fine bubbles have high rigidity and are difficult to deform and do not cause unnecessary movement, the energy loss is small.

ここで用いる多孔体としては、超高分子量ポリエチレンやポリプロピレンなどの略球形粒子を充填して加熱成型したであって、表面は粒子により互いの空隙が分割された独立開孔を構成しており、独立気泡を生成するものを用いる。また略均一な粒子を充填することで、開孔は略格子状に規則的な配置となり、気泡生成時に気泡同士が合一することが少ない。   As the porous body used here, it was filled with substantially spherical particles such as ultra-high molecular weight polyethylene and polypropylene and heat-molded, and the surface constituted an independent opening in which the voids were divided by the particles, Those that generate closed cells are used. Further, by filling the substantially uniform particles, the openings are regularly arranged in a substantially lattice shape, and the bubbles are less likely to coalesce when the bubbles are generated.

また、気泡混入機構部を自動制御することも可能である。
使用者が水栓カランの下に手を差し出すと検知センサーにより手が検知され、制御器により電磁弁が開弁され通水が開始され、気泡混入機構部に空気が供給されるようにすることも可能である。 It is also possible to automatically control the bubble mixing mechanism.
When the user puts his hand under the faucet carran, the hand is detected by the detection sensor, the solenoid valve is opened by the controller, water flow is started, and air is supplied to the bubble mixing mechanism. Is also possible.

また、上記実施の形態では台所シンクで使用する水栓カランについて説明したが、洗面台あるいは浴室で使用するシャワー等にも適用可能であることは言うまでもなく、この場合にも、少ない流量で、気泡を含むシャワー水に均一な良好な外観を現出させると共に、手の肌表面やシンクや洗面ボウルの表面や食器等に良好な汚れ除去効果を付与することができる。   Moreover, although the faucet currant used in the kitchen sink has been described in the above embodiment, it is needless to say that it is also applicable to a washstand or a shower used in the bathroom. A uniform good appearance can be made to appear in the shower water containing water, and a good dirt removing effect can be imparted to the skin surface of the hand, the surface of the sink or wash bowl, tableware and the like.
