次に、本発明の第一実施形態に係るノズル１Ａについて、図１から図９を用いて説明する。なお図中において示す矢印Ａは、ノズル１Ａ内に流入する水の流入方向を示すものとして説明する。   Next, the nozzle 1A according to the first embodiment of the present invention will be described with reference to FIGS. In addition, the arrow A shown in the figure demonstrates as what shows the inflow direction of the water which flows in into 1 A of nozzles.

ノズル１Ａは、水の流出口からノズル１Ａに流入した水に気泡を混入させて気泡混入水とし、当該気泡混入水の流出する流量を断続的に変化させて脈動するような気泡混入水として流出するものである。
また、ノズル１Ａは、図１乃至図４に示すように、全体的に略筒状に形成され、流入部１１と、絞り部１２と、空気導入部１３と、断続的遮断手段１４と、を具備する。 The nozzle 1A mixes bubbles into the water flowing into the nozzle 1A from the water outlet to form bubble mixed water, and flows out as bubble mixed water that pulsates by intermittently changing the flow rate of the bubble mixed water flowing out. To do.
Further, as shown in FIGS. 1 to 4, the nozzle 1 </ b> A is formed in a substantially cylindrical shape as a whole, and includes an inflow portion 11, a throttle portion 12, an air introduction portion 13, and intermittent interruption means 14. It has.

ノズル１Ａの流入部１１は、水の流出口に接続されて、当該水の流出口からの水がノズル１Ａ内に流入する部分である。
ここで、水の流出口は、蛇口に接続されたホースにおける水の吐出口部２であるものとして説明する。 The inflow part 11 of the nozzle 1A is connected to the water outlet and is a part through which water from the water outlet flows into the nozzle 1A.
Here, the water outlet will be described as the water outlet 2 in the hose connected to the faucet.

ノズル１Ａの絞り部１２は、流入部１１からノズル１Ａ内に流入した水の流れを絞って水の流速を増加させる部分である。ノズル１Ａの絞り部１２は、流入部１１よりも下流側に配置される。ノズル１Ａは、絞り部１２から下流側へ流出する水の流速が、絞り部１２の上流側よりも増加するように構成される。   The restricting portion 12 of the nozzle 1A is a portion that restricts the flow of water flowing into the nozzle 1A from the inflow portion 11 and increases the flow rate of water. The throttle portion 12 of the nozzle 1 </ b> A is disposed on the downstream side of the inflow portion 11. The nozzle 1 </ b> A is configured such that the flow rate of water flowing out from the throttle unit 12 to the downstream side is increased as compared with the upstream side of the throttle unit 12.

ノズル１Ａの空気導入部１３は、絞り部１２から下流側へ流出する水に空気が吸引されて気泡が混入され、これが気泡混入水となるように、ノズル１Ａ内に空気を導入する部分である。
ノズル１Ａの空気導入部１３は、ノズル１Ａの外部から、ノズル１Ａにおける絞り部１２の下流側部分近傍に空気を導入する。ノズル１Ａの空気導入部１３における空気の出口の開口は、ノズル１Ａ内における絞り部１２の下流側部分近傍に形成される。 The air introduction part 13 of the nozzle 1A is a part that introduces air into the nozzle 1A so that air is sucked into the water flowing out from the throttle part 12 and bubbles are mixed into the water, and this becomes bubble mixed water. .

したがって、ノズル１Ａによれば、これから流出する気泡混入水による洗浄効果を向上させることができる。 In the nozzle 1A configured as described above, for example, the bubble mixed water flowing out from the outlet 15 is directly sprayed on the object to be cleaned (rice, vegetable, metal member, resin member, building, etc.) The outlet 15 is placed in the water and the object to be cleaned is put into the water flow created by the bubble mixed water flowing out of the outlet 15, and the bubble mixed water that pulsates on the surface of the object to be cleaned is contacted. Let The object to be cleaned that comes into contact with the pulsating bubble mixed water is also cleaned by the pulsating bubble mixed water vibration in addition to the cleaning effect by the bubbles in the bubble mixed water.

The notches 34, 34... In the main body member 30 of the nozzle 1A are respectively formed at the upstream end of the side of the upstream side 30b so as to shift the phase by 90 degrees in the circumferential direction. .. In the main body member 30 of the nozzle 1 </ b> A are formed such that the outer peripheral surface of the upstream end portion of the side portion is cut out to reach the through holes 33.

ノズル１Ａでは、本体部材３０における貫通孔３３と切欠き３４とで構成される空間が、本体部材３０の下流側部３０ｃ内（絞り部１２の下流側部分の近傍におけるノズル１Ａ内）に空気を導入する部分であり、空気導入部１３として構成される。ノズル１Ａの本体部材３０における側部の切欠き３４による開口は、空気導入部１３における空気の入口の開口として構成される。ノズル１Ａの本体部材３０の貫通孔３３における下流側部３０ｃの開口は、空気導入部１３における空気の出口の開口として構成される。   In the nozzle 1 </ b> A, the space formed by the through-hole 33 and the notch 34 in the main body member 30 allows air to enter the downstream portion 30 c of the main body member 30 (inside the nozzle 1 </ b> A in the vicinity of the downstream portion of the throttle portion 12). This is a portion to be introduced, and is configured as an air introduction portion 13.

The opening of the downstream side portion 30 c in the through hole 33 of the main body member 30 of the nozzle 1 </ b> A is configured as an air outlet opening in the air introduction portion 13.

そして、ノズル１Ａの本体部材３０における上流側部３０ｂ内に、本体部材３０の上流側端の開口から接続部材２０における下流側部２０ｃを嵌挿する。このとき、ノズル１Ａの本体部材３０における上流側端部が、接続部材２０におけるフランジ２１に当接するまで、本体部材３０における上流側部３０ｂ内に接続部材２０を嵌挿する。   Then, the downstream portion 20c of the connecting member 20 is inserted into the upstream portion 30b of the main body member 30 of the nozzle 1A from the opening at the upstream end of the main body member 30. At this time, the connecting member 20 is inserted into the upstream portion 30 b of the main body member 30 until the upstream end portion of the main body member 30 of the nozzle 1 </ b> A contacts the flange 21 of the connecting member 20.

このように、ノズル１Ａの本体部材３０における上流側部３０ｂ内に接続部材２０の下流側部２０ｃが嵌挿されることによって、本体部材３０における上流側部３０ｂ内の面（上流側部３０ｂの側部の内側の面、および、底部３０ａの上流側の面）と、接続部材２０における底部２０ａの下流側の面と、で形成される空間で、回転体配置部１６が構成される。
なお、ノズル１Ａの本体部材３０における上流側部３０ｂ内に接続部材２０の下流側部２０ｃが嵌挿された状態では、ノズル１Ａの回転体配置部１６と本体部材３０の下流側部３０ｃとは、その絞り孔３２を介して連通した状態となる。
ノズル１Ａの回転体配置部１６は、回転体４０が配置される部分である。ノズル１Ａの回転体配置部１６は、流入部１１よりも下流側に配置されるとともに、絞り部１２よりも上流側に配置される。 As described above, the downstream side portion 20c of the connecting member 20 is inserted into the upstream side portion 30b of the main body member 30 of the nozzle 1A, whereby the surface in the upstream side portion 30b of the main body member 30 (the side of the upstream side portion 30b). The rotating body arranging portion 16 is configured by a space formed by the inner surface of the portion and the upstream surface of the bottom portion 30a) and the downstream surface of the bottom portion 20a of the connecting member 20.
In the state where the downstream side portion 20c of the connecting member 20 is fitted in the upstream side portion 30b of the main body member 30 of the nozzle 1A, the rotating body arrangement portion 16 of the nozzle 1A and the downstream side portion 30c of the main body member 30 are the same. Then, the communication is established through the throttle hole 32.
The rotating body placement portion 16 of the nozzle 1A is a portion where the rotating body 40 is placed. The rotating body arranging portion 16 of the nozzle 1 </ b> A is arranged on the downstream side of the inflow portion 11 and arranged on the upstream side of the throttle portion 12.

またこのように、ノズル１Ａの本体部材３０における上流側部３０ｂ内に接続部材２０の下流側部２０ｃが嵌挿されることによって、接続部材２０の貫通孔２２とその切欠き２３とで形成される空間、および、本体部材３０における上流側部３０ｂ内の面（上流側部３０ｂの側部の内側の面）と接続部材２０の切欠き２３とで形成される空間で、回転体回転手段１７が構成される。
ノズル１Ａの回転体回転手段１７とは、ノズル１Ａ内に流入した水の水流によって、回転体配置部１６に配置された回転体４０を回転させる手段である。ノズル１Ａでは、回転体回転手段１７によって回転体４０を水の流入方向を軸方向とした周方向に回転させる。
ノズル１Ａの回転体回転手段１７は、流入部１１よりも下流側に配置されるとともに、回転体配置部１６の上流側に配置される。 Further, as described above, the downstream side portion 20c of the connecting member 20 is inserted into the upstream side portion 30b of the main body member 30 of the nozzle 1A, thereby forming the through hole 22 of the connecting member 20 and the notch 23 thereof. In the space and the space formed by the surface in the upstream side portion 30b of the main body member 30 (the surface inside the side portion of the upstream side portion 30b) and the notch 23 of the connecting member 20, the rotating body rotating means 17 is provided. Composed.
The rotating body rotating means 17 of the nozzle 1 </ b> A is a means for rotating the rotating body 40 arranged in the rotating body arranging portion 16 by the water flow of water flowing into the nozzle 1 </ b> A. In the nozzle 1A, the rotating body rotating means 17 rotates the rotating body 40 in the circumferential direction with the water inflow direction as the axial direction.
The rotating body rotating means 17 of the nozzle 1 </ b> A is disposed on the downstream side of the inflow portion 11 and is disposed on the upstream side of the rotating body arranging portion 16.

ノズル１Ａの回転体４０は、回転することによって絞り孔３２（絞り部１２）の上流側の開口３２ａの閉鎖と開放とを順次おこなって、絞り孔３２（絞り部１２）への水の流入を断続的に遮断するものであり、断続的遮断手段１４として構成される。   The rotating body 40 of the nozzle 1 </ b> A sequentially closes and opens the opening 32 a upstream of the throttle hole 32 (throttle part 12) by rotating, thereby allowing water to flow into the throttle hole 32 (throttle part 12). Intermittently interrupts and is configured as intermittent interrupting means 14.

ノズル１Ａの回転体４０は、棒状の部材の軸心方向中央部に円盤状の部材が互いの軸心を一致させて設けられたような形状に構成される。ノズル１Ａの回転体４０における棒状部分の両端部は、それぞれ半球状に構成される。   The rotating body 40 of the nozzle 1 </ b> A is configured in such a shape that a disk-shaped member is provided in the center portion in the axial center direction of the rod-shaped member so that the respective shaft centers coincide with each other. Both end portions of the rod-shaped portion of the rotating body 40 of the nozzle 1A are each formed in a hemispherical shape.

ノズル１Ａの回転体４０は、水の流入方向を軸方向とした周方向に回転可能なように、回転体配置部１６に配置される。
このとき、ノズル１Ａの回転体４０は、その上部の棒状部分の一端部４０ａ側が他端部４０ｂよりも外周側を向くように軸心を傾斜させて、棒状部分の一端部４０ａを接続部材２０の溝２４内に位置させ、棒状部分の他端部４０ｂを本体部材３０の凹部３１に位置させた姿勢で、回転体配置部１６に配置される。このように配置されたノズル１Ａの回転体４０における回転中心は、本体部材３０の凹部３１（底部３０ａ）の中心となる。 The rotating body 40 of the nozzle 1 </ b> A is arranged in the rotating body arrangement unit 16 so as to be rotatable in a circumferential direction with the inflow direction of water as an axial direction.
At this time, the rotating body 40 of the nozzle 1A is tilted so that the one end portion 40a side of the upper rod-shaped portion faces the outer peripheral side of the other end portion 40b, and the one end portion 40a of the rod-shaped portion is connected to the connecting member 20. The other end portion 40 b of the rod-shaped portion is positioned in the recess 24 of the main body member 30, and is disposed in the rotor arrangement portion 16. The rotation center of the rotating body 40 of the nozzle 1A arranged in this way is the center of the recess 31 (bottom 30a) of the main body member 30.

ここで、前述のようにノズル１Ａの本体部材３０における上流側部３０ｂ内に接続部材２０の下流側部２０ｃが嵌挿された状態では、接続部材２０の切欠き２３・２３と回転体配置部１６とは、連通した状態となる。
このため、ノズル１Ａの接続部材２０における上流部から流入した水は、その内部を通って貫通孔２２・２２および切欠き２３・２３（回転体回転手段１７）を通り、回転体配置部１６に流入することとなる。
このように、ノズル１Ａ内部に流入した水が接続部材２０の貫通孔２２・２２と切欠き２３・２３と（回転体回転手段１７）を通ることにより、水の水流方向がノズル１Ａ内部への流入方向（接続部材２０の軸方向）から周方向（反時計周り）となり、回転体配置部１６に流入した水流は螺旋状の流水となる。 Here, as described above, in the state where the downstream side portion 20c of the connecting member 20 is fitted in the upstream side portion 30b of the main body member 30 of the nozzle 1A, the notches 23 and 23 of the connecting member 20 and the rotating body arranging portion. 16 is in a state of communication.
For this reason, the water that has flowed in from the upstream portion of the connecting member 20 of the nozzle 1A passes through the inside thereof, passes through the through holes 22 and 22 and the notches 23 and 23 (rotating body rotating means 17), and enters the rotating body arranging portion 16. Will flow in.
In this way, the water flowing into the nozzle 1A passes through the through holes 22 and 22 and the notches 23 and 23 (rotating body rotating means 17) of the connection member 20, so that the water flow direction of the water flows into the nozzle 1A. From the inflow direction (the axial direction of the connecting member 20) to the circumferential direction (counterclockwise), the water flow that flows into the rotating body arranging portion 16 becomes spiral water flow.

そして、ノズル１Ａの回転体配置部１６の回転体４０は、その円盤状部分にて前記螺旋状の水流を受けることによって周方向（反時計周り）に回転する。
このとき、ノズル１Ａの回転体４０は、その棒状部分の一端部４０ａが接続部材２０の溝２４内を反時計回りに移動し、その棒状部分の他端部４０ｂが本体部材３０の凹部３１内においてその中心（回転体４０の回転中心）より外側の部分の一部に当接するようにして、その軸心の向きを変えながら回転する。
さらにこのとき、ノズル１Ａの回転体４０は、これが回転して棒状部分の他端部４０ｂが絞り孔３２の上流側の開口３２ａ上に位置したときに、当該棒状部分の下端部で当該絞り孔３２の上流側の開口３２ａを閉鎖する。そして、ノズル１Ａの回転体４０は、これがさらに回転して、前記絞り孔３２の上流側の開口３２ａを通過したときに、当該絞り孔３２の上流側の開口３２ａを開放する。 And the rotary body 40 of the rotary body arrangement | positioning part 16 of 1 A of nozzles rotates to the circumferential direction (counterclockwise) by receiving the said spiral water flow in the disk shaped part.
At this time, in the rotating body 40 of the nozzle 1A, one end portion 40a of the rod-shaped portion moves counterclockwise in the groove 24 of the connecting member 20, and the other end portion 40b of the rod-shaped portion is in the recess 31 of the main body member 30. Rotate while changing the direction of the axis so as to contact a part of the portion outside the center (rotation center of the rotating body 40).
Further, at this time, when the rotating body 40 of the nozzle 1A rotates and the other end portion 40b of the rod-shaped portion is positioned on the opening 32a on the upstream side of the throttle hole 32, the throttle hole is formed at the lower end portion of the rod-shaped portion. The opening 32a on the upstream side of 32 is closed. Then, the rotating body 40 of the nozzle 1 </ b> A further rotates and opens the opening 32 a upstream of the throttle hole 32 when it passes through the opening 32 a upstream of the throttle hole 32.

このようにして、ノズル１Ａは、その回転体４０が回転することによって、その棒状部分の下端部で絞り孔３２（絞り部１２）の上流側の開口３２ａの閉鎖と開放とを順次おこなっていき、絞り孔３２（絞り部１２）への水の流入を断続的に遮断する。そしてこのようにして、ノズル１Ａは、本体部材３０における絞り孔３２（絞り部１２）の下流側の開口３２ｂから流出する水の流量を断続的に変化させ、ノズル１Ａの流出口１５から流出する空気混入水の流量も断続的に変化させて、その流出口１５から脈動するような気泡混入水を流出する。
以上のように、ノズル１Ａによれば、回転体回転手段１７によって水流を利用して回転体４０（断続的遮断手段１４）を回転させて本体部材３０の絞り孔３２（絞り部１２）への水の流入を断続的に遮断して、ノズル１Ａから流出する気泡混入水による洗浄効果を向上させることができるものを、簡易構造で実現することができる。 In this manner, the nozzle 1A sequentially closes and opens the opening 32a on the upstream side of the throttle hole 32 (throttle portion 12) at the lower end portion of the rod-like portion as the rotating body 40 rotates. The flow of water into the throttle hole 32 (throttle portion 12) is intermittently blocked. In this manner, the nozzle 1A intermittently changes the flow rate of water flowing out from the opening 32b on the downstream side of the throttle hole 32 (throttle portion 12) in the main body member 30, and flows out from the outlet 15 of the nozzle 1A. The flow rate of the air-containing water is also changed intermittently, and the bubble-containing water that pulsates from the outlet 15 flows out.
As described above, according to the nozzle 1 </ b> A, the rotating body rotating means 17 rotates the rotating body 40 (intermittent blocking means 14) using the water flow to the throttle hole 32 (throttle portion 12) of the main body member 30. What can interrupt | block the inflow of water intermittently and can improve the washing | cleaning effect by the bubble mixed water which flows out out of the nozzle 1A is realizable with a simple structure.

また、ノズル１Ａは、その本体部材３０における下流側部３０ｃ内に筒状に構成される筒部材５０の上流側端部を嵌挿して、筒部材５０を取付けた構成としてもよい。このようにノズル１Ａの本体部材３０に筒部材５０を取付けた際には、筒部材５０の下流側の開口がノズル１Ａの流出口１５として構成される。   Further, the nozzle 1 </ b> A may be configured such that the upstream end portion of the cylindrical member 50 configured in a cylindrical shape is fitted into the downstream side portion 30 c of the main body member 30 and the cylindrical member 50 is attached. When the cylindrical member 50 is attached to the main body member 30 of the nozzle 1A in this way, the opening on the downstream side of the cylindrical member 50 is configured as the outlet 15 of the nozzle 1A.

このようにノズル１Ａに筒部材５０を取付けた際には、ノズル１Ａの空気導入部１３における空気の入口の開口から、ノズル１Ａの流出口１５を遠ざける構成となる。
このため、ノズル１Ａが筒部材５０を具備する構成とすることにより、気泡混入水が、前記ノズル１Ａの流出口１５から飛散って空気導入部１３における空気の入口の開口に流入し、当該空気導入部１３が詰まることを抑制することができる。 Thus, when the cylinder member 50 is attached to the nozzle 1A, the outlet 15 of the nozzle 1A is kept away from the opening of the air inlet in the air introduction portion 13 of the nozzle 1A.
For this reason, the configuration in which the nozzle 1A includes the cylindrical member 50 causes the bubble-mixed water to scatter from the outlet 15 of the nozzle 1A and flow into the opening of the air inlet in the air introduction unit 13, and the air Clogging of the introduction part 13 can be suppressed.

また、ノズル１Ａに取付けた筒部材５０の下流側端部に、シリコンチューブ７０や筒状の部材の一端の開口部にブラシが設けられて構成されるブラシ部材７１等を取付けて（図４参照）、洗浄対象物に当該ブラシやシリコンチューブ等を当接させながら当該洗浄対象物を洗浄してもよい。
また、ノズル１Ａは、洗浄対象物を配置するための容器を筒部材５０内と当該容器内とが連通するように筒部材５０の下流側端部に設け、当該容器内に気泡混入水を直接流出するように構成してもよい。 Further, a brush member 71 or the like constituted by providing a brush at the opening of one end of the cylindrical tube 50 or the cylindrical member is attached to the downstream end of the cylindrical member 50 attached to the nozzle 1A (see FIG. 4). ), The object to be cleaned may be cleaned while bringing the brush, the silicon tube or the like into contact with the object to be cleaned.
In addition, the nozzle 1A is provided with a container for placing an object to be cleaned at the downstream end portion of the cylindrical member 50 so that the inside of the cylindrical member 50 and the inside of the container communicate with each other. You may comprise so that it may flow out.

なお、ノズル１Ａの回転体４０によって絞り孔３２の上流側の開口３２ａを閉鎖する状態とは、絞り孔３２の上流側の開口３２ａと回転体４０との間に若干の隙間が生じて、絞り孔３２の上流側の開口３２ａへの水の流入が少なくなるような状態も含むものとする。   The state in which the opening 32a on the upstream side of the throttle hole 32 is closed by the rotary body 40 of the nozzle 1A means that a slight gap is generated between the opening 32a on the upstream side of the throttle hole 32 and the rotary body 40. A state in which the inflow of water into the opening 32a on the upstream side of the hole 32 is reduced is also included.

また、ノズル１Ａの回転体回転手段１７は、回転体配置部１６に流入した水流が螺旋状の流水となるような、本体部材３０の軸方向に対して傾斜した溝を、本体部材３０における上流側部３０ｂ内の面に形成して構成してもよい。   Further, the rotating body rotating means 17 of the nozzle 1 </ b> A has a groove inclined with respect to the axial direction of the main body member 30 so that the water flow flowing into the rotating body arranging portion 16 becomes a spiral flowing water. You may form and comprise in the surface in the side part 30b.

また、ノズル１Ａは、図５に示すように、本体部材３０における底部３０ａに凹部３１を形成せず、断続的遮断手段１４を六面体で構成される回転体６０としてもよい。この場合、底部３０ａは、例えば外周側から中心側へ向かうに従って下流側へ傾斜する面に形成される。
このようなノズル１Ａでは、その回転体６０は、その側方の面で前記螺旋状の水流を受けることによって回転し、当該転体の下流側の面で、本体部材３０における底部３０ａの上流側面に形成された絞り孔３２の上流側の開口３２ａの閉鎖と開放とをおこなう。 Further, as shown in FIG. 5, the nozzle 1 </ b> A may be configured such that the intermittent blocking means 14 is a rotating body 60 formed of a hexahedron without forming the recess 31 in the bottom 30 a of the main body member 30. In this case, the bottom 30a is formed, for example, on a surface that inclines toward the downstream side from the outer peripheral side toward the center side.
In such a nozzle 1 </ b> A, the rotating body 60 rotates by receiving the spiral water flow on the side surface thereof, and the upstream side surface of the bottom portion 30 a of the main body member 30 on the downstream surface of the rolling body. The opening 32a on the upstream side of the throttle hole 32 formed in is closed and opened.

また、ノズル１Ａの本体部材３０が複数個の絞り孔３２・３２・・・を有する構成とし、当該複数個の絞り孔３２・３２・・・で絞り部１２を構成してもよい。
例えば、図６乃至８に示すように、ノズル１Ａの本体部材３０の絞り孔３２は凹部３１内に三つ形成され、当該三つの絞り孔３２・３２・３２で絞り部１２が構成される。ノズル１Ａの本体部材３０の絞り孔３２・３２・３２は、周方向に６０度ずつ位相をずらしてそれぞれ形成される。ノズル１Ａの本体部材３０の絞り孔３２・３２・３２におけるそれぞれの下流側の開口３２ｂ・３２ｂ・３２ｂは、当該絞り孔３２・３２・３２におけるそれぞれの下流側の開口３２ｂ・３２ｂ・３２ｂから流出する三本の水の水流が一本の水流となるような位置にそれぞれ形成される。 Further, the main body member 30 of the nozzle 1A may be configured to have a plurality of throttle holes 32, 32, and the throttle portion 12 may be configured by the plurality of throttle holes 32, 32,.
For example, as shown in FIGS. 6 to 8, three throttle holes 32 of the main body member 30 of the nozzle 1 </ b> A are formed in the recess 31, and the three throttle holes 32, 32, and 32 constitute the throttle portion 12. The throttle holes 32, 32, and 32 of the main body member 30 of the nozzle 1A are formed with phases shifted by 60 degrees in the circumferential direction. The downstream openings 32b, 32b, 32b in the throttle holes 32, 32, 32 of the main body member 30 of the nozzle 1A flow out from the respective downstream openings 32b, 32b, 32b in the throttle holes 32, 32, 32. Each of the three water streams is formed at a position where it becomes one stream.

そしてこのようなノズル１Ａでは、回転体４０は、これが回転してその棒状部分の他端部４０ｂが一つの絞り孔３２の上流側の開口３２ａ上に位置したときに、当該棒状部分の下端部で当該一つの絞り孔３２の上流側の開口３２ａを閉鎖し、これがさらに回転して前記一つの絞り孔３２の上流側の開口３２ａを通過したときに、当該一つの絞り孔３２の上流側の開口３２ａを開放する。さらに、回転体４０は、前記一つの絞り孔３２の回転体４０の回転方向側に隣接する絞り孔３２の方に回転していき、当該隣接する絞り孔３２においても同様に、絞り孔３２の上流側の開口３２ａの閉鎖と開放とをおこなう。   In such a nozzle 1 </ b> A, when the rotating body 40 rotates and the other end portion 40 b of the rod-shaped portion is positioned on the opening 32 a on the upstream side of one throttle hole 32, the lower end portion of the rod-shaped portion. Then, the opening 32a upstream of the one throttle hole 32 is closed, and when this further rotates and passes through the opening 32a upstream of the one throttle hole 32, the upstream side of the one throttle hole 32 is Opening 32a is opened. Further, the rotary body 40 rotates toward the throttle hole 32 adjacent to the rotation direction side of the rotary body 40 of the one throttle hole 32, and similarly in the adjacent throttle hole 32, The opening 32a on the upstream side is closed and opened.

このように、ノズル１Ａでは、その回転体４０が回転することによって、当該回転体４０の棒状部分の下端部で、三つの（複数の）絞り孔３２・３２・３２のうち少なくとも一つの絞り孔３２の上流側の開口３２ａの閉鎖と開放とを順次おこなっていき、回転体配置部１６から前記少なくとも一つの絞り孔３２への水の流入を断続的に遮断する。そして、さらに回転体４０が回転することによって、前記閉鎖と開放とをおこなった絞り孔３２に隣接する絞り孔３２の上流側の開口３２ａの閉鎖と開放とを順次おこなっていき、回転体配置部１６から前記隣接する絞り孔３２への水の流入を断続的に遮断する。そしてこのようにして、ノズル１Ａは、少なくとも一つの絞り孔３２への水の流入を断続的に遮断して、絞り孔３２・３２・３２（絞り部１２）の下流側の開口３２ｂ・３２ｂ・３２ｂから流出する水の流量を断続的に変化させ、ノズル１Ａの流出口１５から流出する空気混入水の流量も断続的に変化させて、その流出口１５から脈動するような気泡混入水を流出する。   As described above, in the nozzle 1 </ b> A, when the rotary body 40 rotates, at least one of the three (a plurality of) throttle holes 32, 32, and 32 at the lower end portion of the rod-like portion of the rotary body 40. The opening 32a on the upstream side of 32 is sequentially closed and opened, and the inflow of water from the rotating body arranging portion 16 to the at least one throttle hole 32 is intermittently blocked. Further, by further rotating the rotating body 40, the opening 32a on the upstream side of the throttle hole 32 adjacent to the throttle hole 32 that has been closed and opened is sequentially closed and opened, and the rotating body arranging portion The flow of water from 16 to the adjacent throttle hole 32 is intermittently blocked. In this way, the nozzle 1A intermittently blocks the inflow of water into the at least one throttle hole 32, and the openings 32b, 32b, downstream of the throttle holes 32, 32, 32 (throttle section 12). The flow rate of the water flowing out from the outlet 32b is changed intermittently, the flow rate of the aerated water flowing out from the outlet 15 of the nozzle 1A is also changed intermittently, and the bubble mixed water that pulsates from the outlet 15 flows out. To do.

またこのとき、ノズル１Ａでは、本体部材３０における絞り孔３２・３２・３２への水の流入が回転体４０によって遮断されない状態では、絞り孔３２・３２・３２におけるそれぞれの下流側の開口３２ｂ・３２ｂ・３２ｂから水が流出する（三本の水が流出する）。また、ノズル１Ａでは、本体部材３０における一つの絞り孔３２への水の流入が回転体４０によって遮断された状態では、他の二つの絞り孔３２・３２におけるそれぞれの下流側の開口３２ｂ・３２ｂから水が流出する（二本の水が流出する）。
このようにして、ノズル１Ａでは、本体部材３０における複数の絞り孔３２・３２・・・のうち一つの絞り孔３２への水の流入が回転体４０によって遮断された状態であっても、他の絞り孔３２・３２・・・から流出する水を気泡混合水として、これを流出口１５から流出することができる。
したがって、ノズル１Ａによれば、脈動するような気泡混入水をその流出口１５から途切れないように流出させて、その洗浄効果をより向上させることができる。
なお、ノズル１Ａでは、本体部材３０における絞り孔３２・３２・３２の水の流入が回転体４０によって遮断されない状態では、下流側の開口３２ｂ・３２ｂ・３２ｂから流出した三本の水の水流は一本の水流となり、流出口１５からも一本の水流の気泡混入水が流出する。また、ノズル１Ａでは、本体部材３０における一つの絞り孔３２への水の流入が回転体４０によって遮断された状態では、他の二つの絞り孔３２・３２におけるそれぞれの下流側の開口３２ｂ・３２ｂから流出した二本の水の水流となり、流出口１５からも一本の水流の気泡混入水が流出する。 At this time, in the nozzle 1A, when the inflow of water into the throttle holes 32, 32, 32 in the main body member 30 is not blocked by the rotating body 40, the respective downstream openings 32b, Water flows out from 32b and 32b (three waters flow out). Further, in the nozzle 1A, when the inflow of water into one throttle hole 32 in the main body member 30 is blocked by the rotating body 40, the downstream openings 32b and 32b in the other two throttle holes 32 and 32, respectively. Water flows out of the water (two water flows out).
In this manner, in the nozzle 1A, even if the inflow of water into one of the plurality of throttle holes 32, 32... The water flowing out from the throttling holes 32, 32,...
Therefore, according to the nozzle 1 </ b> A, the pulsating bubble mixed water is allowed to flow out from the outlet 15 so as not to be interrupted, and the cleaning effect can be further improved.

Further, in the nozzle 1A, when the inflow of water into one throttle hole 32 in the main body member 30 is blocked by the rotating body 40, the downstream openings 32b and 32b in the other two throttle holes 32 and 32, respectively. The two water streams that have flowed out of the water flow, and the bubble mixed water of one water stream also flows out from the outlet 15.

ノズル１Ａでは、本体部材３０における複数の絞り孔３２・３２・・・の下流側の開口３２ｂ・３２ｂ・・・から流出する複数の水流が、本体部材３０の中心側にそれぞれ近づくように本体部材３０の軸方向に対して斜めに流出するように構成してもよい。
例えば図９（ａ）に示すように、ノズル１Ａの本体部材３０における底部３０ａの下流側の面に、その中央部から下流側方向に突出する山状の凸部を形成し、当該凸部の斜面に３つの（複数の）絞り孔３２・３２・３２の下流側の開口３２ｂ・３２ｂ・３２ｂをそれぞれ形成してもよい。
また図９（ｂ）に示すように、ノズル１Ａの本体部材３０の三つの（複数の）絞り孔３２・３２・３２は、絞り孔３２・３２・３２の上流側の開口３２ａ・３２ａ・３２ａから下流側の開口３２ｂ・３２ｂ・３２ｂに向かって本体部材３０の中心側に近づくように本体部材３０の軸方向に対して傾斜してそれぞれ形成してもよい。
このように、ノズル１Ａの本体部材３０における複数の絞り孔３２・３２・・・の下流側の開口３２ｂ・３２ｂ・・・から流出する複数の水流が、本体部材３０の中心側にそれぞれ近づくように本体部材３０の軸方向に対して斜めに流出する構成とすることにより、より確実に、脈動するような気泡混入水を途切れない一本の水流として、その洗浄効果をより向上させることができる。 In the nozzle 1 </ b> A, the main body member so that the plurality of water flows flowing out from the openings 32 b, 32 b... Downstream of the plurality of throttle holes 32, 32. You may comprise so that it may flow out diagonally with respect to 30 axial directions.
For example, as shown in FIG. 9 (a), on the downstream surface of the bottom portion 30a of the main body member 30 of the nozzle 1A, a mountain-shaped convex portion protruding in the downstream direction from the center portion is formed, and the convex portion You may form the opening 32b * 32b * 32b of the downstream of the three (several) throttle holes 32 * 32 * 32 in a slope.

次に、本発明の第二実施形態に係るノズル１Ｂについて、図１０から図１３を用いて説明する。なお、第二実施形態に係るノズル１Ｂは、第一実施形態に係るノズル１Ａと同様の構成を有する部分があるため、ノズル１Ｂの説明は、ノズル１Ａと同様の構成の部分については適宜省略し、ノズル１Ａの構成と異なる部分を中心に説明する。   Next, a nozzle 1B according to a second embodiment of the present invention will be described with reference to FIGS. In addition, since the nozzle 1B according to the second embodiment has a portion having the same configuration as the nozzle 1A according to the first embodiment, the description of the nozzle 1B is appropriately omitted for the portion having the same configuration as the nozzle 1A. The description will focus on the parts different from the configuration of the nozzle 1A.

ノズル１Ｂは、図１０乃至図１３に示すように、主に、接続部材２０、本体部材３０、回転体４０、および、筒部材５０等で構成される。   As shown in FIGS. 10 to 13, the nozzle 1 </ b> B mainly includes a connection member 20, a main body member 30, a rotating body 40, a cylindrical member 50, and the like.

ノズル１Ｂの本体部材３０は、略有底筒状に形成される。ノズル１Ｂの本体部材３０は、その上流側端が開口し、その下流側端に底部３０ａが配置されたような形状に形成される。
ノズル１Ｂの本体部材３０における側部は、その底部３０ａに比べて肉薄状に形成される。
ノズル１Ｂの本体部材３０における上流側端部には、フランジ３６が形成される。ノズル１Ｂの本体部材３０におけるフランジ３６は、側方に突出するように形成される。
ノズル１Ｂの本体部材３０は、３つの絞り孔３２・３２・３２を有する。 The main body member 30 of the nozzle 1B is formed in a substantially bottomed cylindrical shape. The main body member 30 of the nozzle 1B is formed in such a shape that an upstream end thereof is open and a bottom portion 30a is disposed at the downstream end thereof.
A side portion of the main body member 30 of the nozzle 1B is formed thinner than the bottom portion 30a.
A flange 36 is formed at the upstream end of the main body member 30 of the nozzle 1B. The flange 36 of the main body member 30 of the nozzle 1B is formed so as to protrude sideways.
The main body member 30 of the nozzle 1 </ b> B has three throttle holes 32, 32, and 32.

ノズル１Ｂの本体部材３０は、四つの切欠き３７・３７・・・を有する。
ノズル１Ｂの本体部材３０における切欠き３７・３７・・・は、周方向に９０度ずつ位相をずらすようにして、それぞれ形成される。ノズル１Ｂの本体部材３０における切欠き３７・３７・・・は、フランジ３６を含む外周面の一部が、上端部から下端部に亘って水の流入方向に沿って切欠かれるように形成される。 The main body member 30 of the nozzle 1B has four notches 37, 37.
The notches 37, 37... In the main body member 30 of the nozzle 1B are formed so as to be shifted in phase by 90 degrees in the circumferential direction. The notches 37, 37... In the main body member 30 of the nozzle 1B are formed such that a part of the outer peripheral surface including the flange 36 is notched along the inflow direction of water from the upper end portion to the lower end portion. .

ノズル１Ｂの筒部材５０は、その上流側端および下流側端がそれぞれ開口するような筒状に構成される。ノズル１Ｂの筒部材５０における下流側の開口は、ノズル１Ｂの流出口１５として構成される。
ノズル１Ｂの筒部材５０は、その上流側部３０ｂの内径が本体部材３０におけるフランジ３６を除く部分の外径と略同一に形成されて、当該上流側部３０ｂ内に本体部材３０におけるフランジ３６を除く部分を嵌挿可能に構成される。 The cylindrical member 50 of the nozzle 1B is configured in a cylindrical shape such that its upstream end and downstream end are opened. An opening on the downstream side of the cylindrical member 50 of the nozzle 1B is configured as an outlet 15 of the nozzle 1B.
The cylindrical member 50 of the nozzle 1B is formed so that the inner diameter of the upstream side portion 30b thereof is substantially the same as the outer diameter of the portion excluding the flange 36 in the main body member 30, and the flange 36 in the main body member 30 is provided in the upstream side portion 30b. It is configured to be able to insert and remove the part.

そして、ノズル１Ｂの筒部材５０内に、筒部材５０の上流側端の開口から本体部材３０におけるフランジ３６を除く部分を嵌挿する。このとき、ノズル１Ｂの筒部材５０における上流側端部が本体部材３０におけるフランジ３６に当接するまで、本体部材３０におけるフランジ３６を除く部分を筒部材５０内に嵌挿する。   And the part except the flange 36 in the main body member 30 from the opening of the upstream end of the cylinder member 50 is inserted in the cylinder member 50 of the nozzle 1B. At this time, the portion excluding the flange 36 in the main body member 30 is inserted into the cylindrical member 50 until the upstream end of the cylindrical member 50 of the nozzle 1 </ b> B contacts the flange 36 in the main body member 30.

このように、ノズル１Ｂの筒部材５０内に本体部材３０におけるフランジ３６を除く部分が嵌挿されることによって、筒部材５０の内周面と本体部材３０の切欠き３７が形成されていない部分の外周面とは当接または近接するが、筒部材５０の内周面と本体部材３０の切欠き３７が形成された部分の外周面との間には空間が形成される。この本体部材３０における切欠き３７と筒部材５０の内側の面とで形成される空間で、空気導入部１３が構成される。ノズル１Ｂの本体部材３０における切欠き３７の上端の開口が、空気導入部１３における空気の入口の開口として構成される。ノズル１Ｂの本体部材３０における切欠き３７の下端の開口が、空気導入部１３における空気の出口の開口として構成される。   In this way, by inserting the portion of the main body member 30 excluding the flange 36 into the cylindrical member 50 of the nozzle 1B, the inner peripheral surface of the cylindrical member 50 and the notch 37 of the main body member 30 are not formed. A space is formed between the inner peripheral surface of the cylindrical member 50 and the outer peripheral surface of the portion where the notch 37 of the main body member 30 is formed, although it is in contact with or close to the outer peripheral surface. The air introduction portion 13 is configured by a space formed by the notch 37 and the inner surface of the cylindrical member 50 in the main body member 30. The opening at the upper end of the notch 37 in the main body member 30 of the nozzle 1 </ b> B is configured as an air inlet opening in the air introduction unit 13. The opening at the lower end of the notch 37 in the main body member 30 of the nozzle 1 </ b> B is configured as an air outlet opening in the air introduction part 13.

このように、ノズル１Ｂによれば、本体部材３０における切欠き３７と筒部材５０の内側の面とで形成される空間で空気導入部１３を構成することにより、その幅を細く構成して小型化することができる。   As described above, according to the nozzle 1B, the air introduction portion 13 is configured in the space formed by the notch 37 in the main body member 30 and the inner surface of the cylindrical member 50, so that the width thereof is narrowed and the size is reduced. Can be

また、ノズル１Ｂの内側（上流側と下流側との中途部の内側）は、筒部材５０が本体部材に取付けられた状態において、本体部材３０における切欠き３７・３７・・・の下端側の開口（空気導入部１３における空気の出口の開口）近傍から下流側にいくに従って、本体部材３０の絞り孔３２側に近づくようなテーパ状に形成される。
このため、空気導入部１３における空気の出口の開口から流出する空気は、前記筒部材５０の内側のテーパ状の部分によって本体部材３０における絞り孔３２の下流側の開口３２ｂ側に案内され、当該絞り孔３２の下流側の開口３２ｂから流出した水に、容易に吸引されることとなる。このため、ノズル１Ｂでは、本体部材３０における絞り孔３２の下流側の開口３２ｂから流出する水に確実に気泡を混入させ、これを気泡混入水とすることができる。 Further, the inside of the nozzle 1B (inside the middle part between the upstream side and the downstream side) is located on the lower end side of the notches 37, 37. The taper is formed so as to approach the throttle hole 32 side of the main body member 30 from the vicinity of the opening (opening of the air outlet in the air introduction portion 13) to the downstream side.
For this reason, the air flowing out from the opening of the air outlet in the air introducing portion 13 is guided to the opening 32b side of the main body member 30 downstream of the throttle hole 32 by the tapered portion inside the cylindrical member 50, and The water that flows out from the opening 32b on the downstream side of the throttle hole 32 is easily sucked. For this reason, in the nozzle 1B, bubbles can be reliably mixed into the water flowing out from the opening 32b on the downstream side of the throttle hole 32 in the main body member 30, and this can be used as bubble mixed water.
