Description

本考案は気水混合流を噴出分散せしめる泡シャワーに関する。  The present invention relates to a bubble shower that jets and disperses a gas-water mixed flow.

詳細には、本考案は、旋回筒の筒状壁に形成された１個または複数個の加圧水流入孔を介して、旋回筒の外側から内部に旋回筒の接線方向に例えば水道水のような加圧水を流入させることにより、旋回筒の内部に旋回水流を形成し、その旋回水流の中心部に流体力学的に発生する低圧部と、旋回筒の外部とを、旋回筒の底部に貫通して旋回筒の内部に突出せしめられた空気管によって連通し、空気管を介して吸引された旋回筒の外部の空気を旋回水流に巻き込んで気泡化することにより気水混合流を発生させ、旋回筒の上部に開口を形成すると共に、旋回筒の上部の上側ほどその開口の断面積が小さくなるように旋回筒の上部の開口を絞り、旋回筒上部から低圧部への水または空気の逆流を阻止することによって、低圧部の圧力上昇を防止する気水分散手段を旋回筒の上部の開口の上側に配置し、気水分散手段の下端と旋回筒の上部との間の隙間を介して気水混合流の分散された泡シャワーに関する。  In detail, the present invention provides, for example, tap water in the tangential direction of the swirl tube from the outside to the inside of the swirl tube through one or more pressurized water inflow holes formed in the tubular wall of the swirl tube. By making the pressurized water flow in, a swirling water flow is formed inside the swirl tube, and a low pressure part generated hydrodynamically at the center of the swirl water flow and the outside of the swirl tube penetrate through the bottom of the swirl tube. The swirl tube communicates with the air tube projecting inside the swirl tube, and the air outside the swirl tube sucked through the air tube is entrained in the swirl water flow to generate bubbles, thereby generating a gas-water mixed flow. In addition to forming an opening in the upper part of the swirl tube, the upper opening of the swirl tube is narrowed so that the cross-sectional area of the opening becomes smaller toward the upper side of the swirl tube, thereby preventing backflow of water or air from the upper part of the swirl tube to the low pressure part By preventing the pressure rise in the low pressure part Place the air-water dispersion means on the upper side of the upper opening of the swirl tube, relates to distributed foam shower water-air mixture flow through the gap between the top of the lower end and the pivot tube of the steam-water dispersing means.

更に詳細には、本考案は、気水混合流中の気泡の微小化を促進し、気水分散流として、分散させることができる泡シャワーに関する。  More specifically, the present invention relates to a bubble shower that promotes the miniaturization of bubbles in a gas-water mixed flow and can be dispersed as a gas-water dispersed flow.

従来から、気水混合流を分散させるように構成された気水混合流分散装置（液体の微粒化分散装置）が知られている。この種の気水混合流分散装置（流体の微粒化分散装置）の例としては、例えば実用新案第３１６２８６７号などに記載されたものがある。  Conventionally, an air-water mixed flow dispersion device (liquid atomization dispersion device) configured to disperse an air-water mixed flow is known. As an example of this kind of air-water mixed flow dispersion device (fluid atomization dispersion device), for example, there is one described in Utility Model No. 3162867.

実用新案第３１６２８６７号公報に記載された気水混合流分散装置（流体の微粒化分散装置）では、旋回筒の筒状壁に１個または複数個の加圧水流孔（流体供給孔、水噴出口）が形成されている。更に、加圧水流入孔（流体供給孔、水噴出口）を介して、旋回筒の外部から内部に旋回筒の接線方向に加圧水が流入せしめられ、それにより、旋回筒の内部に旋回水流が形成される。  In the air-water mixed flow dispersion device (fluid atomization dispersion device) described in Japanese Utility Model No. 3162867, one or a plurality of pressurized water flow holes (fluid supply holes, water outlets) are formed in the cylindrical wall of the swivel tube. ) Is formed. Furthermore, pressurized water is caused to flow in the tangential direction of the swirl tube from the outside to the inside of the swirl tube through the pressurized water inflow hole (fluid supply hole, water jet port), thereby forming a swirl water flow inside the swirl tube. The

詳細には、実用新案第３１６２８６７号に記載された気水混合流分散装置（流体の微粒化分散装置、）では、旋回水流の中心部に流体力学的に発生する低圧部と、旋回筒の外部とが、旋回筒の底部を貫通して旋回筒の内部に突出せしめられた空気管（流体噴出管）によって連通せしめられている。  More specifically, in the air / water mixed flow dispersion device (fluid atomization dispersion device) described in Utility Model No. 3162867, a low pressure portion hydrodynamically generated at the center of the swirling water flow, and the outside of the swirl tube Are communicated with each other by an air pipe (fluid ejection pipe) that penetrates the bottom of the swivel cylinder and protrudes into the swivel cylinder.

次いで、に実用新案第３１６２８６７号に記載された気水混合流分散装置（流体の微粒化分散装置）では、空気管（流体噴出管）を介して吸引された旋回筒の外部空気が、旋回水流に巻き込まれ、気泡化せしめられる。その結果、気水混合流が発生せしめられる。  Next, in the air-water mixed flow dispersion device (fluid atomization dispersion device) described in Utility Model No. 3162867, the external air of the swirl cylinder sucked through the air pipe (fluid jet pipe) It is caught in and is made to bubble. As a result, an air-water mixed flow is generated.

詳細には、実用新案第３１６２８６７号に記載された気水混合流分散生装置（流体の微粒化分散装置）では、旋回筒の上部に開口（流体出口）が形成されている。更に旋回筒の上部の上側ほどその開口（流体出口）の断面積が小さくなるように、旋回筒の上部の開口（流体出口）が絞られている。  In detail, in the air / water mixed flow dispersion generating apparatus (fluid atomization dispersing apparatus) described in Utility Model No. 3162867, an opening (fluid outlet) is formed in the upper part of the swivel cylinder. Further, the upper opening (fluid outlet) of the swirl tube is narrowed so that the cross-sectional area of the opening (fluid outlet) becomes smaller toward the upper side of the upper portion of the swirl tube.

また、実用新案第３１６２８６７号に記載された気水混合流分散装置（液体の微粒化分散装置）では、旋回筒の上部の開口（流体出口）から低圧部への水または空気の逆流を阻止することによって、低圧部の圧力上昇を防止するための気水分散手段（流体分散版、気水分散版）が、旋回筒の上部の開口（流体出口）の上側に配置されている。  Further, in the gas-water mixed flow dispersion device (liquid atomization dispersion device) described in Utility Model No. 3162867, the backflow of water or air from the upper opening (fluid outlet) of the swirl tube to the low pressure portion is prevented. Thus, the air / water dispersion means (fluid dispersion plate, air / water dispersion plate) for preventing an increase in pressure in the low-pressure portion is disposed above the opening (fluid outlet) at the top of the swivel tube.

次いで、実用新案第３１６２８６７号に記載された気水混合流分散装置（流体の微粒化分散装置、）では、気水分散手段（流体分散版、気水分散版）の下端と旋回筒の上部との間の隙間を介して、気水混合流が噴出分散せしめられる。  Next, in the air-water mixed flow dispersion device (fluid atomization dispersion device) described in Utility Model No. 3162867, the lower end of the air-water dispersion means (fluid dispersion plate, air-water dispersion plate) and the upper part of the swivel cylinder The air-water mixed flow is ejected and dispersed through the gap between the two.

実用新案第３１６２８６７号  Utility model No. 3162867

ところで実用新案第３１６２８６７号に記載された気水混合流分散装置では、外筒内内部の容積が大きいため、流入する水量及び水圧によって旋回筒１内の圧力が十分得られないため、低圧部Ｐでの空気吸入量が十分導入されない。  By the way, in the air / water mixed flow dispersion apparatus described in Utility Model No. 3162867, the volume in the outer cylinder is large, and therefore the pressure in the swivel cylinder 1 cannot be sufficiently obtained by the amount of water flowing in and the water pressure. Insufficient air intake is introduced.

そのため、実用新案第３１６２８６７号に記載された気水混合分散装置では、気水混合流の分散が著しく阻害され、外部に分散する際の水流が弱くなり、効果が弱くなり、効果が低減する。  Therefore, in the air / water mixing / dispersing device described in Utility Model No. 3162867, the dispersion of the air / water mixed flow is remarkably hindered, the water flow when dispersed outside becomes weak, the effect becomes weak, and the effect is reduced.

その結果、供給される水流量の少ないときには、十分な気泡水としてのシャワー効果が得られない。  As a result, when the supplied water flow rate is small, a sufficient shower effect as bubble water cannot be obtained.

そこで本考案者は鋭意研究を行なった結果、実用新案第３１６２８６７号に記載されている流入水路１１を円筒室７内に追加設置することによって水流の回転数が多くなり、水流量の少ない場合でも低圧部の圧力増大にともなって空気吸入量の増加が計られることを見出したのである。  Therefore, as a result of diligent research, the present inventor has found that the inflow water channel 11 described in Utility Model No. 3162867 is additionally installed in the cylindrical chamber 7 to increase the number of rotations of the water flow, even when the water flow rate is small. It has been found that the amount of air intake can be increased as the pressure in the low pressure part increases.

更に前期流入水路１１及び１２に流入した水流の回転数を円筒室７内で円周方向に２回転し、更に旋回筒１内で回転させ、合計３回転の水流を発生させることによって供給水量の少ない場合でも、十分な効果が得られる。Further, the rotational speed of the water flow flowing into the inflow water channels 11 and 12 in the previous period is rotated twice in the circumferential direction in the cylindrical chamber 7, and further rotated in the swivel cylinder 1, thereby generating a total of three rotations of water flow. Even if the amount is small, a sufficient effect can be obtained.

又実用新案第３１６２８６７号では円筒室７内及び旋回筒１内での回転数が２回あるため、回転流の速度が十分に得られない欠点があった。これを３回転することによって回転速度が序々に上がり最終的には、気水混合流Ｆ３の流速が増加せしめられることを見出したのである。  Further, the utility model No. 3162867 has a drawback that the rotational flow speed cannot be sufficiently obtained because the rotational speed in the cylindrical chamber 7 and the swivel cylinder 1 is twice. It has been found that by rotating this three times, the rotational speed gradually increases, and eventually the flow velocity of the gas-water mixed flow F3 is increased.

即ち、本考案は供給水量又は供給水圧の少ない場合でも気水混合流中の気泡の量を安定的に保つことが出来、供給水量に幅を持った泡シャワーを提供することを目的とする。  That is, an object of the present invention is to provide a bubble shower that can stably maintain the amount of bubbles in the gas-water mixed flow even when the amount of supply water or the supply water pressure is small and has a wide supply water amount.

詳細には本考案は、旋回筒１内に流入する前に水流に加速をつけることによって、旋回筒１の加圧水流孔２に流入するまでに十分な回転速度が得られ、より強力な気水混合流が得られる。  Specifically, in the present invention, by accelerating the water flow before flowing into the swirl tube 1, a sufficient rotational speed can be obtained until it flows into the pressurized water flow hole 2 of the swirl tube 1, and more powerful steam A mixed stream is obtained.

実用新案第３１６２８６７号に記載の考案によれば、外筒内１に形成された流入水路は１ケであったため、供給水量又は水圧が少ない場合に旋回筒１内に十分な圧力を有した水流を導入することが出来なかった。そのため前記旋回筒に十分な加圧水流を導入することが困難となり、その旋回水流の中心部に流体力学的に発生する低圧部の圧力が十分得られず、空気吸入量が少ないことによって、目的の旋回気泡水流が低下し、泡シャワーの効果が低下してしまう欠陥あった。これを解決する手段として、前記外筒内に流入水路１１を更に１ケ設置し、外筒内での水流の回転を２回転することによって、前記旋回筒に流入する水圧を十分加えることが可能になり、前記気水混合流で十分な空気を吸入した微細な気水混合流を発生させることが可能になった。  According to the invention described in Utility Model No. 3162867, since there is only one inflow water channel formed in the outer cylinder 1, a water flow having sufficient pressure in the swivel cylinder 1 when the amount of supplied water or water pressure is small Could not be introduced. For this reason, it becomes difficult to introduce a sufficient pressurized water flow into the swirling cylinder, the pressure of the low pressure part generated hydrodynamically at the center of the swirling water flow cannot be obtained sufficiently, and the amount of air suction is small, There was a defect that the swirling bubble water flow was lowered and the effect of foam shower was lowered. As a means for solving this problem, it is possible to apply a sufficient amount of water pressure flowing into the swivel cylinder by installing one more inflow water channel 11 in the outer cylinder and rotating the rotation of the water flow in the outer cylinder twice. Thus, it is possible to generate a fine air / water mixed flow in which sufficient air is sucked in the air / water mixed flow.

その結果、請求項１に記載された泡シャワーによれば、例えば実用新案第３１６２８６７号に記載された気水混合流分散装置のように導入水路が１ケの場合よりも導水水路を追加設置し２ケにすることによって流入水の旋回速度が上昇し、前記低圧部に発生する圧力が増し、空気管３より吸入される空気量が増加し、円筒室内に多量の気水混合流が発生する。  As a result, according to the bubble shower described in claim 1, for example, as in the air-water mixed flow dispersion device described in Utility Model No. 3162867, an additional water conduit is installed rather than the case where there is only one introduction channel. By using two, the swirling speed of the inflowing water increases, the pressure generated in the low pressure portion increases, the amount of air sucked from the air pipe 3 increases, and a large amount of air-water mixed flow is generated in the cylindrical chamber. .

請求項２に記載の泡シャワーでは、気水分散手段としての円形の流体分散板の軸が円筒室の中心軸と一致して固定されている。  In the foam shower according to the second aspect, the axis of the circular fluid dispersion plate as the air / water dispersion means is fixed in alignment with the central axis of the cylindrical chamber.

そのため請求項１に記載の泡シャワーでは流入水路を更に１ケ所追加設置することによって流入水の回転速度が上昇する。  Therefore, in the bubble shower according to the first aspect, the rotational speed of the inflowing water is increased by additionally installing one inflowing water channel.

以下本考案の泡シャワーの第１の実施形態について説明する。
図１は第１の実施形態の泡シャワーの正面断面図、図２は第１の実施形態の泡シャワーの平面図、図３は図１のＩ−Ｉ線に沿った断面図である。Hereinafter, a first embodiment of the bubble shower of the present invention will be described.
FIG. 1 is a front sectional view of a bubble shower according to the first embodiment, FIG. 2 is a plan view of the bubble shower according to the first embodiment, and FIG. 3 is a sectional view taken along line I-I in FIG.

第１の実施形態の泡シャワーでは図１及び図３に示すように、旋回筒１の筒状壁に例えば１ケの加圧水流入孔２が形成されている。第２の実施形態の泡シャワーでは、代わりに複数個の加圧水流入孔２を旋回筒１の筒状壁に形成することも可能である。  In the bubble shower of the first embodiment, as shown in FIGS. 1 and 3, for example, one pressurized water inflow hole 2 is formed in the cylindrical wall of the swivel cylinder 1. In the bubble shower of the second embodiment, a plurality of pressurized water inflow holes 2 can be formed in the cylindrical wall of the swivel cylinder 1 instead.

第１の実施形態の泡シャワーでは、図１及び図３に示すように、加圧水流入孔２から供給された加圧水Ｆ１が加圧水流入孔２を介して旋回筒１の外部から内部に旋回筒１の接線方向に流入せしめられ、それにより、旋回筒１の内部に旋回水流Ｆ２が形成される。その結果、旋回水流Ｆ２の中心部に流体力学的に低圧部Ｐが発生する。In the bubble shower of the first embodiment, as shown in FIGS. 1 and 3, the pressurized water F 1 supplied from the pressurized water inflow hole 2 passes through the pressurized water inflow hole 2 from the outside to the inside of the swivel cylinder 1. The swirl water flow F 2 is formed inside the swirl tube 1. As a result, hydrodynamic low pressure portion P is generated in the central portion of the turning water flow F 2.

更に、第１の実施形態の泡シャワーでは、図１に示すように、低圧部Ｐと、旋回筒１の外部とが、旋回筒１の底部を貫通して旋回筒１の内部に突出せしめられた空気管３によって連通せしめられている。そのため、空気管３を介して吸引された外部空気Ａが、低圧部Ｐの低圧効果によって旋回水流Ｆ２に巻き込まれ、気泡化せしめられる。その結果、気水混合流Ｆ３が発生せしめられる。Furthermore, in the bubble shower of the first embodiment, as shown in FIG. 1, the low pressure part P and the outside of the swivel cylinder 1 penetrate the bottom of the swivel cylinder 1 and protrude into the swirl cylinder 1. The air pipe 3 communicates with each other. Therefore, the external air A sucked through the air pipe 3 is entrained in the swirling water flow F 2 by the low pressure effect of the low pressure portion P and is bubbled. As a result, the steam-water mixture flow F 3 is made to occur.

また、第１の実施形態の泡シャワーでは、図１にしめすように、旋回筒１の上部に出口開口４が形成されている。更に、旋回筒１の上部の上側ほどその出口開口４の断面積が小さくなるように、旋回筒１の上部の出口開口４が絞られている。そのため、気水混合流Ｆ２が出口開口４を通過するときに、気水混合流Ｆ３の流速が増加せしめられる。Moreover, in the bubble shower of 1st Embodiment, the exit opening 4 is formed in the upper part of the turning cylinder 1, as shown in FIG. Further, the outlet opening 4 at the top of the swivel cylinder 1 is narrowed so that the cross-sectional area of the outlet opening 4 becomes smaller toward the upper side of the upper part of the swirl cylinder 1. Therefore, when the air / water mixed flow F 2 passes through the outlet opening 4, the flow velocity of the air / water mixed flow F 3 is increased.

更に第１の実施形態の泡シャワーでは、図１に示すように、旋回筒１の上部の出口開口４から低圧部Ｐへの水または空気の逆流を阻止する事によって、低圧部Ｐの圧力上昇を防止するための流体分散板５が旋回筒１の上部の出口開口４の上側に配置されている。  Furthermore, in the bubble shower of the first embodiment, as shown in FIG. 1, the pressure increase in the low pressure portion P is prevented by preventing the backflow of water or air from the outlet opening 4 at the top of the swivel tube 1 to the low pressure portion P. A fluid dispersion plate 5 is disposed on the upper side of the outlet opening 4 at the top of the swivel cylinder 1.

詳細には、円形の流体分散板は旋回筒の中心軸と一致した分散軸６の低圧部側の一端に固定され、他端を円筒室７に固定されている。  Specifically, the circular fluid dispersion plate is fixed to one end on the low pressure portion side of the dispersion shaft 6 that coincides with the central axis of the swivel cylinder, and the other end is fixed to the cylindrical chamber 7.

分散軸６の長さは、低圧部の圧力が最も低く保たれ、外気空気吸引量が最大になるように設定されている。  The length of the dispersion shaft 6 is set so that the pressure in the low pressure portion is kept lowest and the amount of outside air suction is maximized.

詳細には、第１の実施形態の泡シャワーでは、図１に示すように、気水混合流分割分散孔８を、円周方向および半径方向に複数設けた天井部９を有する円筒室７を旋回筒１と同心に気水混合流Ｆ３の分散下流側に設け、噴出分散させた気水混合流Ｆ４を円筒室７に導入せしめ、後続の気水混合流との連続的旋回衝突により、気水混合流中の気泡の一層の微小化を促進せしめる。In detail, in the bubble shower of 1st Embodiment, as shown in FIG. 1, the cylindrical chamber 7 which has the ceiling part 9 which provided the air-water mixed flow division | segmentation dispersion | distribution hole 8 in multiple numbers in the circumferential direction and radial direction is provided. It provided the dispersion downstream of the swirl tube 1 and the concentric gas-water mixture flow F 3, allowed the introduction of steam-water mixture flow F 4 which has ejected dispersed into a cylindrical chamber 7, by successive turning collision with subsequent steam-water mixture flow , Promoting further miniaturization of bubbles in the gas-water mixed flow.

次いで、第１に実施形態の泡シャワーでは、複数の気水混合流分割分散孔８から泡シャワー流として外部に広い範囲に噴出される。  Next, in the bubble shower of the first embodiment, a plurality of gas-water mixed flow divided dispersion holes 8 are ejected to the outside as a bubble shower flow in a wide range.

詳細には第１の実施形態の泡シャワーでは、加圧水Ｆ１より流入した水流を最初流入水路１１に導入せしめ次に流入水路１２に導入され最終的には旋回筒１に導入され、前記加圧口より前記旋回筒に導入される過程まで水流の速度が順次増大され、その結果、旋回水流Ｆ２の中心部に流体力学的な低圧部Ｐからより大きく発生する。Specifically, in the bubble shower of the first embodiment, the water flow that flows in from the pressurized water F 1 is first introduced into the inflow water channel 11, then introduced into the inflow water channel 12, and finally introduced into the swivel cylinder 1, the rate of increase of the water flow sequentially to the process of being introduced into the revolving tube from the mouth, thereby generating greater the hydrodynamic low pressure portion P to the center of turning water flow F 2.
