Description

本開示は、噴流を噴射する吐出装置に関する。 TECHNICAL FIELD The present disclosure relates to an ejection device that ejects a jet.

浴室設備等の水回り設備に噴流を噴射可能な吐出装置を組み込む場合がある。近年、噴流がユーザに付与する刺激を多様化する試みがなされている。この一例として、特許文献1には、噴流の噴射方向が平面内で揺動する揺動噴射を実行可能な吐出装置が記載されている。 In some cases, a discharge device capable of ejecting a jet is incorporated in plumbing equipment such as bathroom equipment. In recent years, attempts have been made to diversify the stimulation given to the user by the jet. As an example, Patent Literature 1 describes a discharge device capable of performing swing jet in which the direction of jet flow swings within a plane.

特開2017-108830号公報JP 2017-108830 A

本願発明者は、検討を進めた結果、次の新たな認識を得るに至った。浴槽等のベースに吐出装置を固定する場合、吐出装置全体の向きが変えられなくなる。このため、噴流の噴射方向が時間的に変化したとしても、噴流が描く軌跡(以下、噴流軌跡ともいう)の位置そのものは変化しない。よって、同じ噴流軌跡上でしかユーザは刺激を受けることができず、ユーザによっては退屈に感じることがある。特許文献1の開示技術は、このような観点から工夫を講じたものではなく、改良の余地があった。 As a result of further studies, the inventors of the present application came to obtain the following new recognition. When the discharge device is fixed to the base of a bathtub or the like, the orientation of the entire discharge device cannot be changed. Therefore, even if the injection direction of the jet changes with time, the position itself of the trajectory drawn by the jet (hereinafter also referred to as the jet trajectory) does not change. Therefore, the user can receive stimulation only on the same jet trajectory, and some users may feel bored. The technique disclosed in Patent Literature 1 is not contrived from such a point of view, and there is room for improvement.

本開示の目的の1つは、揺動噴射を実行する場合に、ユーザの好みに応じて噴流軌跡の位置を調整できる技術を提供することにある。 One of the objects of the present disclosure is to provide a technique that can adjust the position of the jet trajectory according to the user's preference when performing the swing jet.

前述の課題を解決するための本開示のある態様は吐出装置である。この態様の吐出装置は、噴流の噴射方向が平面内で揺動する揺動噴射を実行可能な噴射部材と、前記噴射部材を移動可能に支持する支持体と、を備える吐出装置。 A certain aspect of the present disclosure for solving the aforementioned problems is a discharge device. The ejection device of this aspect includes an ejection member capable of executing swing ejection in which the ejection direction of the jet flow swings within a plane, and a support body that movably supports the ejection member.

噴射流路36は、高さ方向Hに対向する一対の対向面72と、幅方向Wに対向する一対の内側面74とを備える。ここでの高さ方向H及び幅方向Wは、噴射流路36の中心線CL2に直交し、互いに直交する方向をいう。ここでの中心線L2は、一対の対向面72及び一対の内側面74がなす断面の中心線をいう。主流路70は、その中心線CL2に直交する断面において、矩形状をなす。本実施形態の主流路70は、この断面において、幅方奥Wに沿った内幅寸法Lwより高さ方向Hに沿った高さ寸法Lhが小さい矩形状をなす。 The injection flow path 36 includes a pair of opposing surfaces 72 facing in the height direction H and a pair of inner side surfaces 74 facing in the width direction W. As shown in FIG. The height direction H and the width direction W here refer to directions orthogonal to the center line CL2 of the injection flow path 36 and orthogonal to each other. The centerline L2 here refers to the centerline of the cross section formed by the pair of facing surfaces 72 and the pair of inner side surfaces 74 . The main flow path 70 has a rectangular cross section perpendicular to the center line CL2. The main flow path 70 of the present embodiment has a rectangular cross section in which the height dimension Lh along the height direction H is smaller than the inner width dimension Lw along the depth W in the width direction.

本実施形態の噴射流路36は、高さ方向Hから見て(図6の視点から見て)、主流路70の中心線CL2を対称軸として左右対称な断面形状を持つ。噴射流路36は、主流路70の中心線CL2に沿った方向から見て(図7の視点から見て)、その中心線CL2に対して高さ方向Hに対称な断面形状を持つ。この条件は、主流路70において少なくとも満たされ、本実施形態では出口孔38においても満たされる。 The jet flow path 36 of the present embodiment has a symmetrical cross-sectional shape with the center line CL2 of the main flow path 70 as the axis of symmetry when viewed from the height direction H (viewed from the viewpoint of FIG. 6). The injection flow path 36 has a cross-sectional shape that is symmetrical in the height direction H with respect to the center line CL2 when viewed from the direction along the center line CL2 of the main flow path 70 (viewed from the viewpoint of FIG. 7). This condition is met at least in the main flow path 70 and in this embodiment also in the outlet holes 38 .

出口孔38は、噴射部材32の外面部に開口する。本実施形態の出口孔38は噴射部材32の前面部に開口し、噴射部材32は前方に噴流Jを噴射する。出口孔38の内幅寸法は、前側(図6の紙面上側)に向かう途中で、上流側の流路(主流路70)の内幅寸法より小さくなるように設定される。出口孔38は、前側に向かうに連れて内幅寸法が連続的に広がるように形成される。 The exit hole 38 opens into the outer surface of the injection member 32 . The outlet hole 38 of this embodiment opens in the front part of the injection member 32, and the injection member 32 injects the jet J forward. The inner width dimension of the outlet hole 38 is set to be smaller than the inner width dimension of the upstream flow path (main flow path 70) on the way to the front side (upper side of the paper surface of FIG. 6). The outlet hole 38 is formed so that the inner width dimension continuously widens toward the front side.

図6、図8を参照する。噴射部材32は、揺動噴射を実行可能な流体素子76である。揺動噴射とは、噴流Jの噴射方向Daが平面内で揺動するように時間的に変化する噴射をいう。この揺動噴射によって、噴射部材32から波状の噴流Jが放射状に広がるように伝搬する。この「噴射方向Da」は、噴射部材32から外部に噴流Jが出るときの噴射方向Daをいう。「平面内で揺動」とは、噴射方向の方向軸線が揺動中心Sc周りに平面内で揺動することと同義である。噴射方向Daが平面内で揺動する過程で、その平面の法線方向に僅かに噴射方向が変動する場合も、ここでいう「平面内で揺動」の条件を満たす。たとえば、平面に対して平面の法線方向に±10°だけ噴射方向Daがずれる場合も、「平面内で揺動」の条件を満たす。 6 and 8 are referred to. The injection member 32 is a fluid element 76 capable of performing an oscillating injection. Oscillating injection refers to an injection in which the injection direction Da of the jet J fluctuates with time in a plane. Due to this swinging injection, a wave-like jet J is propagated from the injection member 32 so as to spread radially. This "injection direction Da" refers to the injection direction Da when the jet flow J is emitted from the injection member 32 to the outside. “Swinging within a plane” means that the directional axis of the injection direction swings within a plane around the swinging center Sc. Even if the injection direction slightly fluctuates in the normal direction of the plane while the injection direction Da fluctuates within the plane, the condition of "fluctuation within the plane" is satisfied. For example, even when the ejection direction Da deviates from the plane by ±10° in the normal direction of the plane, the condition of "fluctuation within the plane" is satisfied.

揺動噴射を実現するため、本実施形態の噴射部材32は、次の構成を持つ。詳しくは、主流路70は、給液路22から液体が流入する入口流路78と、入口流路78から液体が流入する一対の中間流路80A、80Bと、一対の中間流路80A、80Bのそれぞれから流入する液体が合流する合流室82とを備える。 In order to realize swing injection, the injection member 32 of this embodiment has the following configuration. Specifically, the main channel 70 includes an inlet channel 78 into which the liquid flows from the liquid supply channel 22, a pair of intermediate channels 80A and 80B into which the liquid flows from the inlet channel 78, and a pair of intermediate channels 80A and 80B. and a confluence chamber 82 in which the liquids flowing in from each of the .

噴射流路36は、入口流路78内にて下流側に向かう液体の流れを遮る第1壁部84を備える。一対の中間流路80A、80Bは、第1壁部84に対して幅方向Yの両側に設けられる。一対の中間流路80A、80Bは、幅方向Yの片側に設けられる第1中間流路80Aと、その反対側に設けられる第2中間流路80Bとを含む。噴射流路36は、合流室82内にて下流側に向かう液体の流れを遮る第2壁部86を備える。第2壁部86には、出口孔38が形成される。 The jet channel 36 includes a first wall portion 84 that blocks the downstream flow of liquid in the inlet channel 78 . A pair of intermediate flow paths 80A and 80B are provided on both sides in the width direction Y with respect to the first wall portion 84 . The pair of intermediate flow paths 80A and 80B includes a first intermediate flow path 80A provided on one side in the width direction Y and a second intermediate flow path 80B provided on the opposite side. The jet flow path 36 includes a second wall portion 86 that blocks the flow of liquid toward the downstream side within the confluence chamber 82 . An exit hole 38 is formed in the second wall portion 86 .

本実施形態の噴射部材32の動作を説明する。図9、図10を参照する。本図では、主な液体の流れ方向に矢印を付して示す。 The operation of the injection member 32 of this embodiment will be described. 9 and 10 are referred to. In this figure, arrows indicate main liquid flow directions.

入口流路78内に流入した液体は、一対の中間流路80A、80Bを介して合流室82内に流入する。第1中間流路80Aは合流室82に第1内部噴流F1を噴射する。第2中間流路80Bは合流室82に第2内部噴流F2を噴射する。これら噴流F1、F2は、液体のランダム性に起因する揺らぎの影響を受けて、いずれか一方が他方よりも勢いの強い支配的な流れ(以下、支配流という)となる。図9は、第1内部噴流F1が支配流となる第1流れ状態を示す。図10は、第2内部噴流F2が支配流となる第2流れ状態を示す。 The liquid that has flowed into the inlet channel 78 flows into the confluence chamber 82 via the pair of intermediate channels 80A and 80B. The first intermediate flow path 80A injects the first internal jet F1 into the confluence chamber 82. As shown in FIG. The second intermediate flow path 80B injects the second internal jet F2 into the confluence chamber 82. As shown in FIG. These jets F1 and F2 are affected by fluctuations caused by the randomness of the liquid, and one of them becomes a dominant flow (hereinafter referred to as a dominant flow) with stronger force than the other. FIG. 9 shows a first flow state in which the first internal jet F1 is the dominant flow. FIG. 10 shows a second flow state in which the second internal jet F2 is the dominant flow.

図9に示すように、第1流れ状態にあるとき、第2内部噴流F2は、第1内部噴流F1との衝突によって流れを阻害される。これに対して、第1内部噴流F1は、第2壁部86に衝突するまで勢いを持って流れ、合流室82内で折り返して第2内部噴流F2と合流し、第2内部噴流F2の勢いを増幅する。この結果、第2内部噴流F2が支配流となる第2流れ状態に切り替わる。 As shown in FIG. 9, when in the first flow state, the second internal jet F2 is obstructed from flow by collision with the first internal jet F1. On the other hand, the first internal jet F1 flows with momentum until it collides with the second wall portion 86, turns back in the confluence chamber 82, joins with the second internal jet F2, and the momentum of the second internal jet F2 is increased. amplifies the As a result, the flow state is switched to the second flow state in which the second internal jet F2 is the dominant flow.

図10に示すように、第2流れ状態にあるとき、第1内部噴流F1は、第2内部噴流F2との衝突によって流れを阻害される。これに対して、第2内部噴流F2は、第2壁部86に衝突するまで勢いを持って流れ、合流室82内で折り返して第1内部噴流F1と合流し、第1内部噴流F1の勢いを増幅する。この結果、第1内部噴流F1が支配流となる第1流れ状態に切り替わる。 As shown in FIG. 10, when in the second flow state, the first internal jet F1 is obstructed in flow by collision with the second internal jet F2. On the other hand, the second internal jet F2 flows with momentum until it collides with the second wall portion 86, turns back in the confluence chamber 82, joins with the first internal jet F1, and the momentum of the first internal jet F1 is increased. amplifies the As a result, the flow state is switched to the first flow state in which the first internal jet F1 is the dominant flow.

以上の結果、第1流れ状態と第2流れ状態とが周期的に切り替わる。第1流れ状態にあるとき、第1内部噴流F1は、出口孔38を通り抜ける液流F3を形成する。この液流F3は、幅方向Wの一方側(図中右側)かつ前側に向かう速度ベクトルを持つ。第2流れ状態にあるとき、第2内部噴流F2は、出口孔38を通り抜ける液流F4を形成する。この液流F4は、幅方向Wの他方側(図中左側)かつ前側に向かう速度ベクトルを持つ。これらの流れ状態が周期的に切り替わることで、出口孔38を通り抜ける液流F3、F4は、幅方向Wでの速度ベクトルの大きさ(ベクトル量)が周期的に増減する。この結果、噴流Jの噴射方向Daが平面P(図3、図4参照)内で揺動する揺動噴射が実行される。流体素子76である噴射部材32は、静止した状態のまま、このように揺動噴射を単独で実行可能である。この「平面P」は、本実施形態では、出口孔38の中心線CL1上にて左右方向Yに平行に設けられ、水平面に対して傾斜している。 As a result, the first flow state and the second flow state are periodically switched. When in the first flow state, the first internal jet F1 forms a liquid flow F3 through the exit hole 38. As shown in FIG. This liquid flow F3 has a velocity vector directed to one side (the right side in the figure) in the width direction W and to the front side. When in the second flow state, the second internal jet F2 forms a liquid flow F4 through the exit hole 38. As shown in FIG. This liquid flow F4 has a velocity vector directed to the other side in the width direction W (the left side in the drawing) and to the front side. By periodically switching between these flow states, the liquid flows F3 and F4 passing through the outlet hole 38 periodically increase or decrease in magnitude of the velocity vector (vector amount) in the width direction W. As a result, an oscillating injection is performed in which the injection direction Da of the jet J oscillates within the plane P (see FIGS. 3 and 4). The injection member 32, which is the fluidic element 76, can independently perform such an oscillating injection while remaining stationary. In this embodiment, the "plane P" is provided parallel to the left-right direction Y on the center line CL1 of the outlet hole 38, and is inclined with respect to the horizontal plane.

図1、図3を参照する。以上の噴射部材32は、浴槽16内に浴槽水Wを貯留した場合に、その浴槽水Wの水面WSより下方に配置される。この噴射部材32は、浴槽16内に貯留される浴槽水W中において噴流Jを噴射する。この噴射部材32の内部には、噴流Jの噴射を停止した状態にあるとき、浴槽16内から流入する浴槽水Wが貯留される。 Please refer to FIGS. The injection member 32 described above is arranged below the water surface WS of the bathtub water W when the bathtub water W is stored in the bathtub 16 . The injection member 32 injects a jet J into the bathtub water W stored in the bathtub 16 . Bathtub water W flowing from the bathtub 16 is stored inside the injection member 32 when the injection of the jet J is stopped.

以上の吐出装置10の効果を説明する。図11A~図11Cを参照する。噴流Jが他の流体を受けることなく伝搬すると仮定した場合に、噴流Jが描く軌跡を噴流軌跡JTという。揺動噴射によって得られる噴流軌跡JTは、噴射部材32から放射状に広がる扇状をなす。この噴流軌跡JTは、噴流Jの揺動方向Dbの両側に設けられる一対の端部領域R1と、それらの間に設けられる中間領域R2とを備える。 Effects of the ejection device 10 described above will be described. Please refer to FIGS. 11A-11C. A trajectory drawn by the jet J assuming that the jet J propagates without receiving other fluid is called a jet trajectory JT. The jet trajectory JT obtained by the swing injection forms a fan shape that spreads radially from the injection member 32 . The jet trajectory JT includes a pair of end regions R1 provided on both sides of the jet J in the swinging direction Db, and an intermediate region R2 provided therebetween.

揺動噴射によって得られる噴流Jは、一回の揺動周期においてユーザの同じ部位に当たるように動く。特に、噴流軌跡JTの端部領域R1を通る噴流Jは折り返すように動く。よって、ユーザの同じ部位に当たる時間間隔が相対的に長くなる(図11B参照)。これに対して、噴流軌跡JTの中間領域R2を通る噴流Jは直線的に動く。よって、ユーザの同じ部位に当たる時間間隔が相対的に短くなる(図11C参照)。このため、端部領域R1を通る噴流Jは、ユーザに相対的に強い刺激を付与し易くでき、中間領域R2を通る噴流Jは、ユーザに相対的に弱い刺激を付与し易くできる。つまり、ユーザによって受ける感覚に違いがあるものの、噴流軌跡JT内での位置によって、噴流が付与する刺激の強さに大きなコントラストが付き易くなる。例えば、ユーザの両脇腹の近傍には端部領域R1を通る噴流Jが強い刺激を付与でき、ユーザの背骨の近傍には中間領域R2を通る噴流Jが弱い刺激を付与できる。 The jet J obtained by the swing jet moves so as to hit the same part of the user in one swing cycle. In particular, the jet J passing through the end region R1 of the jet trajectory JT moves so as to turn back. Therefore, the time interval between hits on the same part of the user becomes relatively long (see FIG. 11B). On the other hand, the jet J passing through the intermediate region R2 of the jet trajectory JT moves linearly. Therefore, the time interval between hits on the same part of the user is relatively shortened (see FIG. 11C). Therefore, the jet J passing through the end region R1 can easily give a relatively strong stimulus to the user, and the jet J passing through the middle region R2 can easily give a relatively weak stimulus to the user. In other words, although there are differences in sensations received by users, the strength of the stimulation imparted by the jet tends to have a large contrast depending on the position within the jet trajectory JT. For example, the jets J passing through the end regions R1 can provide strong stimulation near the user's flanks, and the jets J passing through the middle region R2 can provide weak stimulation near the user's spine.

図12Aを参照する。これに対して、旋回噴射によって得られる噴流軌跡JTは、噴射部材から放射状に広がる立体的な円錐面状をなす。このような噴流軌跡JTを通る噴流Jは、一回の旋回周期においてユーザの同じ部位に当たるように動くことがない。よって、揺動噴射によって得られる噴流Jと異なり、噴流軌跡JTの位置によって、ユーザの同じ部位に当たる時間間隔が一定に近くなる。このため、噴流が付与する刺激の強さに大きなコントラストが付き難くなる。 See FIG. 12A. On the other hand, the jet trajectory JT obtained by the swirl injection forms a three-dimensional conical surface that spreads radially from the injection member. The jet J passing through such a jet trajectory JT does not move so as to hit the same part of the user in one turning cycle. Therefore, unlike the jet J obtained by the swing jet, the time interval of hitting the same part of the user becomes nearly constant depending on the position of the jet trajectory JT. For this reason, it becomes difficult to obtain a large contrast in the strength of the stimulation given by the jet.

(A1)本実施形態の吐出装置10は、揺動噴射を実行可能な噴射部材32を備える。よって、このように強弱のある刺激をユーザに付与でき、噴流Jがユーザに付与する刺激の多様化を図ることができる。特に、このような効果を得るうえで、ポンプ24の出力の制御が不要となるため、吐出システム18の簡素化を図ることができる。 (A1) The ejection device 10 of the present embodiment includes an ejection member 32 capable of performing swing ejection. Therefore, it is possible to provide the user with a strong and weak stimulus in this manner, and to diversify the stimulus provided by the jet J to the user. In particular, since it is not necessary to control the output of the pump 24 in order to obtain such effects, the discharge system 18 can be simplified.

浴槽水W中において噴流Jを噴射する場合、浴槽水Wを巻き込むことで噴流Jの勢いが徐々に弱くなる。よって、噴射部材32からの距離が離れるほど、ユーザに噴流Jが当たるときの勢いが弱くなる。これを利用して、ユーザは、噴射部材32に対するユーザの距離を調整することで、噴流Jが当たるときの強さを調整できる。 When the jet J is ejected in the bathtub water W, the momentum of the jet J is gradually weakened by involving the bathtub water W. Therefore, the greater the distance from the injection member 32, the weaker the force of the jet J hitting the user. Using this, the user can adjust the strength of the jet J by adjusting the user's distance from the injection member 32 .

図12A~図12Cを参照する。仮に、噴射部材32が旋回噴射を実行した場合、噴流軌跡JTは立体的な円錐面状をなす。よって、噴射部材32に対するユーザの距離が離れたとき、噴流軌跡JTの断面形状が二次元的に大きく変化してしまう(図12B、図12C参照)。このため、ユーザは、噴射部材32に対するユーザの距離を調整する場合に、噴流Jの当たる位置を直感的に把握し難くなる。 See FIGS. 12A-12C. If the injection member 32 performs a swirling injection, the jet locus JT forms a three-dimensional conical surface. Therefore, when the distance of the user from the injection member 32 increases, the cross-sectional shape of the jet locus JT changes greatly two-dimensionally (see FIGS. 12B and 12C). Therefore, when adjusting the user's distance to the injection member 32, it becomes difficult for the user to intuitively grasp the position where the jet J hits.

(A2)図13A、図13Bを参照する。噴射部材32が揺動噴射を浴槽水W中で実行した場合、重力の影響を受けることがほとんどないため、噴流軌跡JTは平面的な扇状をなす。よって、噴射部材32に対するユーザの距離が離れたとき、噴流軌跡JTの断面形状が変化したとしても、一次元的な大きい変化にとどめることができる(図13A、図13B参照)。このため、ユーザは、噴射部材32に対するユーザの距離を調整する場合に、噴流Jの当たる位置を直感的に把握し易くなる。ひいては、旋回噴射を実行する場合と比べ、ユーザの所望の箇所に所望の強さの噴流Jが当たるように、噴射部材32に対する距離及び位置を調整し易くできる。 (A2) Refer to FIGS. 13A and 13B. When the injection member 32 performs the swing injection in the bathtub water W, it is hardly affected by gravity, so the jet locus JT forms a planar fan shape. Therefore, even if the cross-sectional shape of the jet trajectory JT changes when the user moves away from the injection member 32, the change can be limited to a large one-dimensional change (see FIGS. 13A and 13B). Therefore, when the user adjusts the user's distance to the injection member 32, it becomes easier for the user to intuitively grasp the position where the jet stream J strikes. As a result, the distance and position to the injection member 32 can be easily adjusted so that the user's desired location is hit with the desired strength of the jet J, compared to the case of executing the swirl injection.

(A3)噴射部材32は、浴槽水W中にて噴流Jを噴射する。よって、浴槽水Wを巻き込みつつ噴流Jをユーザに当てることができる。このため、空気中にて噴流Jを噴射する場合と比べ、噴流Jがユーザに当たる範囲を広げることができる。この他にも、空気中にて噴流Jを噴射する場合と異なり、細かい液滴の飛散によって、意図せず周囲が濡れてしまう事態を避けることができる。 (A3) The injection member 32 injects the jet stream J in the bathtub water W. Therefore, the user can be hit with the jet J while the bathtub water W is involved. Therefore, compared to the case where the jet J is ejected in the air, the range where the jet J hits the user can be widened. In addition, unlike the case where the jet J is jetted in the air, it is possible to avoid a situation in which the surroundings are unintentionally wet due to scattering of fine droplets.

(A4)噴射部材32は、揺動噴射の実行によって、広範囲に伝搬する波状の噴流Jを放射状に噴射できる。よって、広範囲に噴流Jを伝搬させるために要する吐出装置10の個数を減らすことができる。これに伴い、清掃箇所を減らすことができ、清掃作業の容易化を図れる。 (A4) The injection member 32 can radially inject the wavy jet flow J that propagates over a wide range by executing the swing injection. Therefore, it is possible to reduce the number of ejection devices 10 required to propagate the jet J over a wide range. As a result, the number of locations to be cleaned can be reduced, and the cleaning work can be facilitated.

(A5)噴射部材32は、揺動噴射を実行可能な流体素子76である。よって、噴流Jの噴射方向を時間的に変化させるうえで専用の動力源が不要となり、吐出装置10の簡素化を図れる。 (A5) The injection member 32 is a fluidic element 76 capable of performing swing injection. Therefore, a dedicated power source is not required for temporally changing the injection direction of the jet J, and the discharge device 10 can be simplified.

吐出装置10の他の特徴を説明する。図3、図4を参照する。本実施形態の支持体34は、噴射部材32を移動可能に支持する。これを実現するため、噴射部材32の接続部54は、支持体34の内筒部48に回転自在に接続される。この支持体34は、回転中心線CL4周りに回転可能に噴射部材32を支持する。回転中心線CL4は、内筒部48の中心軸線(不図示)と同軸上に設けられる。本実施形態では、ベース28の貫通孔30の中心軸線(不図示)と平行に設けられる。 Other features of the ejection device 10 will be described. Please refer to FIGS. The support 34 of this embodiment movably supports the injection member 32 . To achieve this, the connecting portion 54 of the injection member 32 is rotatably connected to the inner tubular portion 48 of the support 34 . This support 34 supports the injection member 32 so as to be rotatable around the rotation center line CL4. The rotation center line CL4 is provided coaxially with the center axis line (not shown) of the inner cylindrical portion 48 . In this embodiment, it is provided parallel to the central axis (not shown) of the through hole 30 of the base 28 .

噴射部材32は、噴射部材32を動かすときにユーザによって操作される操作部88を備える。本実施形態の操作部88は突出部58の外周部が構成する。 The injection member 32 includes an operating portion 88 that is operated by the user when moving the injection member 32 . The operating portion 88 of the present embodiment is configured by the outer peripheral portion of the projecting portion 58 .

図3、図14を参照する。噴射部材32は、回転中心線CL4周りに回転することによって、第1位置Pa1(図3参照)と第2位置Pa2(図14参照)とに配置可能である。本実施形態では、噴射部材32を回転中心線CL4周りに90°回転させることで、噴射部材32を第1位置Pa1から第2位置Pa2に配置できる。 3 and 14 are referred to. The injection member 32 can be arranged at a first position Pa1 (see FIG. 3) and a second position Pa2 (see FIG. 14) by rotating around the rotation center line CL4. In this embodiment, the injection member 32 can be arranged from the first position Pa1 to the second position Pa2 by rotating the injection member 32 by 90° around the rotation center line CL4.

図15を参照する。図の二点鎖線は、図13Bの噴流軌跡JTの位置に対応する。ユーザは、噴射部材32を移動させることによって、噴流軌跡JTの位置を調整できる。本実施形態では、噴射部材32を回転中心線CL4周りに回転させることによって、噴流軌跡JTの位置を、噴射軌跡JTの中心線CL3周りに回転させるように調整できる。図15では、噴射部材32が第1位置Pa1にあるときの噴射軌跡JTの位置Pb1と、噴射部材32が第2位置Pa2にあるときの噴射軌跡JTの位置Pb2とを示す。 Please refer to FIG. The two-dot chain line in the figure corresponds to the position of the jet trajectory JT in FIG. 13B. The user can adjust the position of the jet locus JT by moving the injection member 32 . In this embodiment, by rotating the injection member 32 around the rotation center line CL4, the position of the jet locus JT can be adjusted so as to rotate around the center line CL3 of the injection locus JT. FIG. 15 shows the position Pb1 of the injection locus JT when the injection member 32 is at the first position Pa1 and the position Pb2 of the injection locus JT when the injection member 32 is at the second position Pa2.

図3、図15を参照する。噴射部材32は、第1位置Pa1に配置されるとき、噴射流路36の幅方向W(図14の紙面直交方向)が左右方向Yに沿うような位置に設けられる。これにより、噴射部材32は、噴射方向が左右に揺動するような揺動噴射を実行できる。この結果、噴射軌跡JTは、位置Pb1で示すように、左右方向Yに放射状に広がるように描かれる。 3 and 15 are referred to. The injection member 32 is provided at a position such that the width direction W of the injection flow path 36 (the direction orthogonal to the paper surface of FIG. 14) is along the left-right direction Y when arranged at the first position Pa1. As a result, the injection member 32 can perform swing injection such that the injection direction swings left and right. As a result, the injection trajectory JT is drawn so as to spread radially in the horizontal direction Y, as indicated by the position Pb1.

図14、図15を参照する。噴射部材32は、第2位置Pa2に配置されるとき、噴射流路36の高さ方向H(図14の紙面直交方向)が左右方向Yに沿うような位置に設けられる。これにより、噴射部材32は、噴射方向が上下に揺動するような揺動噴射を実行できる。この結果、噴射軌跡JTは、位置Pb2で示すように、噴流軌跡JTの中心線CL3及び左右方向Yと直交する方向に広がるように描かれる。 14 and 15 are referred to. The injection member 32 is provided at a position such that the height direction H of the injection flow path 36 (the direction perpendicular to the paper surface of FIG. 14) is along the left-right direction Y when arranged at the second position Pa2. As a result, the injection member 32 can perform swing injection such that the injection direction swings up and down. As a result, the jet trajectory JT is drawn so as to extend in a direction orthogonal to the center line CL3 and the left-right direction Y of the jet trajectory JT, as indicated by the position Pb2.

(B1)本実施形態の支持体34は、噴射部材32を移動可能に支持する。よって、揺動噴射を実行する場合に、噴射部材32を移動させることによって、ユーザの好みに応じて噴流軌跡JTの位置を調整できるようになる。 (B1) The support 34 of the present embodiment movably supports the injection member 32 . Therefore, by moving the injection member 32, it is possible to adjust the position of the jet locus JT according to the user's preference when performing the swing injection.

(B2)特に、噴射部材32は揺動噴射を実行する。よって、前述のように、噴流軌跡JT内での位置によって、噴流Jが付与する刺激の強さが異なる。このような噴射部材32を移動させることによって、強い刺激を付与できる噴流軌跡JTの端部領域R1の位置を調整できる。よって、ユーザの好みに応じて、ユーザに強い刺激を付与できる位置を調整できるようになる。 (B2) In particular, the injection member 32 performs swing injection. Therefore, as described above, the strength of the stimulation given by the jet J differs depending on the position within the jet trajectory JT. By moving the injection member 32 in this manner, the position of the end region R1 of the jet trajectory JT that can impart a strong stimulus can be adjusted. Therefore, it becomes possible to adjust the position where a strong stimulus can be given to the user according to the user's preference.

(B3)支持体34は、揺動噴射を実行可能な噴射部材32を回転可能に支持する。よって、噴流軌跡JTの中心線CL3周りで回転させるように噴流軌跡JTの位置を調整できる。このため、噴流軌跡JTの中間領域R2の位置は大きく動かすことなく、その端部領域R1の位置を大きく動かすことができる。ひいては、弱い刺激を付与できる中間領域R2の位置は大きく変えることなく、強い刺激を付与できる端部領域R1の位置を大きく変えるような調整を実現できる。 (B3) The support member 34 rotatably supports the injection member 32 capable of performing swing injection. Therefore, the position of the jet trajectory JT can be adjusted so as to rotate around the center line CL3 of the jet trajectory JT. Therefore, the position of the end region R1 of the jet trajectory JT can be largely moved without greatly moving the position of the intermediate region R2. As a result, it is possible to realize adjustment such that the position of the end region R1, to which a strong stimulus can be applied, is largely changed without greatly changing the position of the intermediate region R2, to which a weak stimulus can be applied.

A seal member 90 is arranged between the connecting portion 54 of the injection member 32 and the inner tubular portion 48 of the support 34 . A seal member 90 seals between them. The sealing member 90 is an elastic body such as rubber. The seal member 90 of this embodiment is mounted in a groove portion 92 formed in the outer peripheral portion of the injection member 32 .

シール部材90は、支持体34の送り流路62から、噴射部材32の噴射流路36以外の箇所への液漏れを規制できる。本実施形態での「噴射流路36以外の箇所」とは戻し流路64である。この結果、噴射部材32に対する液体の供給量を確保でき、所望の勢いの噴流Jを安定して噴射できる。一般に、可動要素と固定要素の間では液漏れが生じ易い。このような可動要素としての噴射部材32と、固定要素としての支持体34との間での液漏れを防止できる。 The seal member 90 can restrict liquid leakage from the feed channel 62 of the support 34 to locations other than the injection channel 36 of the injection member 32 . “A portion other than the injection flow path 36 ” in this embodiment is the return flow path 64 . As a result, the amount of liquid supplied to the injection member 32 can be ensured, and the jet J with a desired force can be stably injected. In general, liquid leakage is likely to occur between the movable element and the fixed element. Liquid leakage between the injection member 32 as such a movable element and the support 34 as a fixed element can be prevented.

The ejection device 10 of this embodiment differs from that of the first embodiment in the ejection member 32 . The centerlines CL1 and CL5 of the outlet hole 38 of the injection channel 36 and the main channel 70, respectively, are eccentric from the rotation centerline CL4 of the injection member 32 and parallel to the rotation centerline CL4. Thereby, the center line CL1 of the outlet hole 38 is provided at a position different from the rotation center line CL4.

図17を参照する。本図では、揺動噴射を実行して得られる噴流軌跡JTと、その噴流軌跡JTを中心線CL3周りに回転させて得られる回転軌跡RTとを示す。この回転軌跡RTは、噴射部材32を回転中心線CL4周りに回転させた場合に、噴射部材32から噴射される噴流JTが届き得る最大の範囲を示す。実線の軌跡JT、RTは、本実施形態の構造によって得られる。破線の軌跡JT、RTは、出口孔38の中心線CL1と回転中心線CL4とが同軸にある構造によって得られる。 See FIG. This figure shows the jet trajectory JT obtained by executing the swing injection, and the rotational trajectory RT obtained by rotating the jet trajectory JT around the center line CL3. This rotational trajectory RT indicates the maximum range that the jet flow JT jetted from the jetting member 32 can reach when the jetting member 32 is rotated around the rotation center line CL4. Solid-line trajectories JT and RT are obtained by the structure of this embodiment. The dashed trajectories JT, RT are obtained by a structure in which the centerline CL1 of the exit hole 38 and the rotation centerline CL4 are coaxial.

(C)本実施形態によれば、図17に示すように、出口孔38の中心線CL1を回転中心線CL4と同軸に設ける場合と比べ、噴射部材32を回転させるうえで、噴流Jの届く範囲を広げることができる。 (C) According to the present embodiment, as shown in FIG. 17, compared to the case where the center line CL1 of the outlet hole 38 is coaxial with the rotation center line CL4, it is easier for the jet J to reach when the injection member 32 is rotated. You can extend the range.

この他に、本実施形態の吐出装置10は、前述した(A1)~(A5)、(B1)~(B3)で説明した効果を得られる。 In addition, the ejection device 10 of the present embodiment can obtain the effects described in (A1) to (A5) and (B1) to (B3) above.

(第3実施形態)図18を参照する。本実施形態の吐出装置10は、第1実施形態と比べて、噴射部材32が異なる。噴射流路36の出口孔38及び主流路70それぞれの中心線CL1、CL5は、噴射部材32の回転中心線CL4と交差し、かつ、回転中心線CL4に対して傾斜する位置に設けられる。これにより、出口孔38の中心線CL1は、回転中心線CL4とは異なる位置に設けられる。 (Third Embodiment) FIG. 18 is referred to. The ejection device 10 of this embodiment differs from that of the first embodiment in the ejection member 32 . The centerlines CL1 and CL5 of the outlet hole 38 of the injection channel 36 and the main channel 70 respectively intersect the rotation centerline CL4 of the injection member 32 and are provided at positions inclined with respect to the rotation centerline CL4. Thereby, the center line CL1 of the outlet hole 38 is provided at a position different from the rotation center line CL4.

本実施形態によっても、前述した(C)の効果を得られる。この他にも、本実施形態によれば、出口孔38の中心線CL1を回転中心線CL4に対して偏心させる場合と比べ、噴射流路36の上流側部分の位置を回転中心線CL4に近づけることができる。これに伴い、噴射流路36の上流側部分の径方向寸法の小型化を図れる。 The above-described effect (C) can also be obtained according to this embodiment. In addition, according to the present embodiment, compared to the case where the center line CL1 of the outlet hole 38 is eccentric with respect to the rotation center line CL4, the position of the upstream portion of the injection flow path 36 is brought closer to the rotation center line CL4. be able to. Along with this, the radial dimension of the upstream portion of the injection flow path 36 can be reduced.

この他に、本実施形態の吐出装置10は、前述した(A1)~(A5)、(B1)~(B3)で説明した効果を得られる。 In addition, the ejection device 10 of the present embodiment can obtain the effects described in (A1) to (A5) and (B1) to (B3) above.

(第4実施形態)図19、図20を参照する。本実施形態の支持体34は、噴射部材32を上下に傾動可能に支持する。これを実現するうえで、噴射部材32の接続部54は、支持体34に対して、ボールジョイント、ピン等を介して、傾動可能に接続される。噴射部材32は、支持体34に対する接続位置を通る傾動中心CL6周りに上下に傾動可能となる。これにより、噴射部材32が噴射する噴流Jが通る噴流軌跡JT全体の位置を調整できる。 (Fourth Embodiment) FIGS. 19 and 20 are referred to. The support 34 of this embodiment supports the injection member 32 so that it can tilt up and down. In order to realize this, the connection portion 54 of the injection member 32 is connected to the support 34 via a ball joint, a pin, or the like so as to be tiltable. The injection member 32 can tilt up and down around a tilting center CL6 passing through the connection position with respect to the support 34 . Thereby, the position of the entire jet locus JT along which the jet J injected by the injection member 32 passes can be adjusted.

本実施形態では、噴射部材32を上下に傾動させることで、噴射部材32を第1位置Pc1と第2位置Pc2との間に配置できる。噴射部材32は、第1位置Pc1に配置されるとき、出口孔38の中心線CL1が前側に向かって上向きに延びるように設けられる。本実施形態では、主流路70の中心線CL5も同様の条件を満たす。噴射部材32は、第2位置Pc2に配置されるとき、出口孔38の中心線CL1が前側に向かって下向きに延びるように設けられる。本実施形態では、主流路70の中心線CL5も同様の条件を満たす。 In this embodiment, the injection member 32 can be arranged between the first position Pc1 and the second position Pc2 by vertically tilting the injection member 32 . The injection member 32 is provided such that the center line CL1 of the outlet hole 38 extends upward toward the front side when arranged at the first position Pc1. In this embodiment, the center line CL5 of the main flow path 70 also satisfies the same condition. The injection member 32 is provided such that the center line CL1 of the outlet hole 38 extends downward toward the front side when arranged at the second position Pc2. In this embodiment, the center line CL5 of the main flow path 70 also satisfies the same condition.

本実施形態の噴射部材32は、噴射流路36の幅方向W(図20の紙面直交方向)が左右方向Yに沿うような位置に設けられる。これにより、噴射部材32は、噴射方向が左右に揺動するような揺動噴射を実行できる。 The injection member 32 of the present embodiment is provided at a position such that the width direction W of the injection flow path 36 (the direction perpendicular to the paper surface of FIG. 20) is along the left-right direction Y. As shown in FIG. As a result, the injection member 32 can perform swing injection such that the injection direction swings left and right.

本実施形態の吐出装置10の効果を説明する。噴流Jの噴射を停止した状態にあるとき、噴射流路36内の浴槽水を排出する場合がある。このとき、噴射部材32を下向きに傾動させることによって、元の位置に噴射部材32を配置したままとするより、噴射流路36内から浴槽水を排出し易くできる(図20参照)。ひいては、噴射流路36内での浴槽水の残留を避けることで良好な衛生性を得られる。 Effects of the ejection device 10 of the present embodiment will be described. When the injection of the jet J is stopped, the bathtub water in the injection flow path 36 may be discharged. At this time, by tilting the injection member 32 downward, it is possible to more easily discharge the bathtub water from the injection flow path 36 than if the injection member 32 were left at its original position (see FIG. 20). As a result, good sanitation can be obtained by avoiding the bathtub water remaining in the injection flow path 36 .

噴流Jの噴射を開始しようとする場合、噴射流路36内を浴槽水で満たすまで、噴射流路36内に浴槽水を供給する必要がある。このとき、噴射部材32を上向きに傾動させることによって、元の位置に噴射部材32を配置したままとするより、噴射流路36内のエアを排気し易くできる(図19参照)。仮に、噴射流路36内にエアが残存してしまうと、噴流Jの形状が乱れる恐れがある。例えば、揺動噴射を実行する場合、噴流Jの形状の乱れとして、波状の噴流の振幅が大幅に小さくなる恐れがある。この点、本実施形態によれば、噴射流路36内のエアを排気し易くすることで、噴流Jの形状の安定化を図れる。 When the injection of the jet J is to be started, it is necessary to supply the bathtub water into the injection flow path 36 until the inside of the injection flow path 36 is filled with the bathtub water. At this time, by tilting the injection member 32 upward, the air in the injection flow path 36 can be more easily discharged than when the injection member 32 is left at its original position (see FIG. 19). If air remains in the injection flow path 36, the shape of the jet J may be disturbed. For example, when the swing injection is performed, the shape of the jet J may be disturbed, and the amplitude of the wavy jet may be greatly reduced. In this regard, according to the present embodiment, the shape of the jet J can be stabilized by making it easier to exhaust the air in the injection flow path 36 .

この他に、本実施形態の吐出装置10は、前述した(A1)~(A5)、(B1)、(B2)で説明した効果を得られる。 In addition, the ejection device 10 of the present embodiment can obtain the effects described in (A1) to (A5), (B1), and (B2) above.

(第5実施形態)図21を参照する。本実施形態は、第1実施形態と比べて、吐出装置10の構成が異なる。吐出装置10は、噴射部材32を駆動する動力源94を備える。動力源94は、例えば、モータ等である。動力源94は、制御部26による制御のもと、噴射部材32を左右方向Yに揺動させることによって、噴射部材32に揺動噴射を実行させることが可能である。 (Fifth Embodiment) FIG. 21 is referred to. This embodiment differs from the first embodiment in the configuration of the ejection device 10 . Dispensing device 10 includes a power source 94 that drives injection member 32 . The power source 94 is, for example, a motor or the like. The power source 94 swings the injection member 32 in the left-right direction Y under the control of the control unit 26, thereby causing the injection member 32 to perform the swing injection.

本実施形態の吐出装置10は、前述の(A1)~(A4)で説明した効果を得られる。このように、前述の(A1)~(A4)の効果を得るうえで、吐出装置10は、噴射部材32に液体が供給されたとき、他要素との協働、及び、噴射部材32単独の何れかによって、噴射部材32に揺動噴射を実行させることが可能であればよい。ここでの他要素とは、例えば、第5実施形態のように、動力源94と制御部26の組み合わせである。第1実施形態等では、噴射部材32単独によって、揺動噴射を実行させる例を説明した。 The ejection device 10 of the present embodiment can obtain the effects described in (A1) to (A4) above. Thus, in order to obtain the effects (A1) to (A4) described above, the ejection device 10 cooperates with other elements when liquid is supplied to the ejection member 32, and the ejection member 32 alone Any one of them may be used as long as it is possible to cause the injection member 32 to perform the swing injection. Other elements here are, for example, a combination of the power source 94 and the control section 26 as in the fifth embodiment. In the first embodiment and the like, an example in which the injection member 32 alone performs the swing injection has been described.
