Description

気液分離器、それを備えたオゾン水生成装置、および、それを備えた衛生器具用洗浄装置Gas-liquid separator, ozone water generating apparatus including the same, and sanitary equipment cleaning apparatus including the same
　本発明は、気液分離器、それを備えたオゾン水生成装置、および、それを備えた衛生器具用洗浄装置に関する。 The present invention relates to a gas-liquid separator, an ozone water generating device including the same, and a sanitary equipment cleaning device including the same.
　例えば、特開２００９－２４０９８６号公報（以下、特許文献１という）に記載された気液分離器は、圧力容器と仕切部材とを備えている。圧力容器の下部には、溶解液を導入させる導入口と、圧力容器から溶解液を導出させる導出口とが形成されている。 For example, a gas-liquid separator described in JP 2009-240986 A (hereinafter referred to as Patent Document 1) includes a pressure vessel and a partition member. In the lower part of the pressure vessel, an introduction port for introducing the solution and an outlet port for extracting the solution from the pressure vessel are formed.
　特許文献１に記載された気液分離器においては、導入空間の底面積よりも導出空間の底面積が大きくなるように仕切部材を圧力容器の内部に配置することにより、溶解液の流れを導出空間において減速させることができる。 In the gas-liquid separator described in Patent Document 1, the flow of the solution is derived by disposing the partition member inside the pressure vessel so that the bottom area of the lead-out space is larger than the bottom area of the introduction space. It can be decelerated in space.
　導出空間において溶解液の流速が減速されることにより、気体を溶解液から十分に分離させることができるため、導出口から気体が流出することを抑制することができる。 Since the gas can be sufficiently separated from the solution by reducing the flow rate of the solution in the outlet space, the gas can be prevented from flowing out from the outlet.
　特許文献１に記載の気液分離器においては、圧力容器の上部に、排気弁が取り付けられている。排気弁は、弁箱と弁体とバネとを有している。弁箱には、流入口と排気口とが形成されている。弁体は、弁箱内に配置され且つ排気口を開閉する。バネは、排気口を閉塞するように弁体を付勢する。 In the gas-liquid separator described in Patent Document 1, an exhaust valve is attached to the upper part of the pressure vessel. The exhaust valve has a valve box, a valve body, and a spring. An inflow port and an exhaust port are formed in the valve box. The valve body is disposed in the valve box and opens and closes the exhaust port. The spring biases the valve body so as to close the exhaust port.
　圧力容器の内部の気体の圧力が所定の圧力以上である場合には、弁体が排気口を開放することにより、圧力容器の内部の気体が排気口から排出される。 When the pressure of the gas inside the pressure vessel is equal to or higher than a predetermined pressure, the valve body opens the exhaust port, whereby the gas inside the pressure vessel is discharged from the exhaust port.
特開２００９－２４０９８６号公報JP 2009-240986 A
　しかしながら、特許文献１に記載の気液分離器においては、排気弁なしでは圧力容器の内部に気体を貯留させることが困難であるため、圧力容器の内部に気体を十分に貯留させることができない。つまり、特許文献１に記載の気液分離器においては、圧力容器の内部に、気体を貯留するための空間を積極的に形成させていない。 However, in the gas-liquid separator described in Patent Document 1, it is difficult to store gas inside the pressure vessel without an exhaust valve, and therefore gas cannot be sufficiently stored inside the pressure vessel. That is, in the gas-liquid separator described in Patent Document 1, a space for storing gas is not actively formed inside the pressure vessel.
　圧力容器の内部において気体の貯留が不十分である場合には、気体が貯留された空間を液体が通過することがほとんどないため、液体から気体が完全に分離しないまま、気体を含む液体が液体とともに導出口から流出する場合がある。そのため、液体から気体を十分に且つ効率よく分離させることができない。一方、排気弁を備えていなくても、比較的簡易な構成によって、圧力容器の内部に導入された液体を導出口から排出させるまでに、容器の内部において液体から気体を効率よく分離させることが可能な気液分離器が望まれている。 When the gas is not sufficiently stored inside the pressure vessel, the liquid hardly passes through the space where the gas is stored, so the liquid containing the gas is not separated from the liquid. At the same time, it may flow out from the outlet. Therefore, gas cannot be separated from the liquid sufficiently and efficiently. On the other hand, even if an exhaust valve is not provided, gas can be efficiently separated from the liquid inside the container before the liquid introduced into the pressure container is discharged from the outlet through a relatively simple configuration. A possible gas-liquid separator is desired.
　そこで、本発明の目的は、比較的簡易な構成を有する気液分離器であって、当該気液分離器に供給される液体から気体を効率よく分離させることが可能な気液分離器を提供することである。 Accordingly, an object of the present invention is to provide a gas-liquid separator having a relatively simple configuration, which can efficiently separate gas from the liquid supplied to the gas-liquid separator. It is to be.
　本発明に従った気液分離器は、容器と仕切部材とを備えている。容器は、天井面と、底面と、周壁とを有している。周壁は、天井面と底面との間を上下方向に延びている。仕切部材は、容器の内部において底面から上方に向かって延びている。仕切部材は、容器の外部から内部に導入された液体が流通するための導入室と、容器の内部から外部に導出される液体が流通するための導出室とに容器の内部を区画する。導入室の容積は、導出室の容積よりも小さい。 The gas-liquid separator according to the present invention includes a container and a partition member. The container has a ceiling surface, a bottom surface, and a peripheral wall. The peripheral wall extends in the vertical direction between the ceiling surface and the bottom surface. The partition member extends upward from the bottom surface inside the container. The partition member divides the inside of the container into an introduction chamber through which the liquid introduced from the outside of the container flows and a lead-out chamber through which the liquid led out from the inside of the container flows. The volume of the introducing chamber is smaller than the volume of the outlet chamber.
　周壁には、第１の開口と第２の開口とが形成されている。第１の開口は、容器の外部と導入室とを連通させる。第２の開口は、容器の外部と導出室とを連通させる。容器には、第３の開口が形成されている。第３の開口は、第１の開口および第２の開口よりも上方に配置され、且つ、導出室と容器の外部とを連通させる。また、容器の内部には、導出室の上方に配置され、且つ、気体を貯留する空間が形成されている。 A first opening and a second opening are formed in the peripheral wall. The first opening allows communication between the outside of the container and the introduction chamber. The second opening allows communication between the outside of the container and the outlet chamber. A third opening is formed in the container. The third opening is disposed above the first opening and the second opening, and communicates the lead-out chamber and the outside of the container. In addition, a space for storing gas is formed inside the container and disposed above the outlet chamber.
　本発明によれば、気体が貯留される空間が導出室の上方に配置されている。これにより、容器の外部から導入室に流入した溶液が、気体が貯留された空間を通過する際に、溶液が気体に容易に触れることができるため、溶液に含まれる未溶解気体を溶液から効率よく分離させることができる。また、気体が貯留される空間が導出室の上方に配置されていることにより、第１の開口から導入室に勢いよく溶液が流入する場合でも、第３の開口から溶液が噴出することを防止することができる。 According to the present invention, the space for storing the gas is arranged above the outlet chamber. As a result, when the solution flowing into the introduction chamber from the outside of the container passes through the space in which the gas is stored, the solution can easily touch the gas, so that the undissolved gas contained in the solution is efficiently removed from the solution. Can be separated well. In addition, since the space for storing the gas is arranged above the outlet chamber, the solution is prevented from being ejected from the third opening even when the solution flows into the introduction chamber from the first opening. can do.
　また、本発明によれば、導入室の容積が導出室の容積よりも小さいことにより、導入室から導出室に移動した溶液の流速は、導出室において減速される。そのため、導出室を流れる溶液に含まれる未溶解の気体が、溶液とともに、第２の開口を通って容器の外部に排出されることを抑制することができる。 Further, according to the present invention, since the volume of the introduction chamber is smaller than the volume of the discharge chamber, the flow rate of the solution that has moved from the introduction chamber to the discharge chamber is reduced in the discharge chamber. Therefore, it is possible to suppress the undissolved gas contained in the solution flowing through the outlet chamber from being discharged to the outside of the container through the second opening together with the solution.
　このように、本発明によれば、排気弁を備えていなくても、比較的簡易な構成によって、容器の内部に導入された液体を第２の開口から排出させるまでに、容器の内部において液体から気体を効率よく分離させることができる。したがって、本発明によれば、比較的簡易な構成を有する気液分離器であって、当該気液分離器に供給される液体から気体を効率よく分離させることが可能な気液分離器を提供することができる。 As described above, according to the present invention, even if no exhaust valve is provided, the liquid introduced into the container is discharged from the second opening with a relatively simple configuration until the liquid is discharged from the second opening. Gas can be efficiently separated from the gas. Therefore, according to the present invention, there is provided a gas-liquid separator having a relatively simple configuration and capable of efficiently separating gas from the liquid supplied to the gas-liquid separator. can do.
　本発明に従った気液分離器の容器の平面視において、好ましくは、第１の開口と第２の開口とは、互いに対向している。仕切部材は、好ましくは、筒形状を持つ仕切周壁を有している。好ましくは、容器の平面視において、仕切周壁の一端側には、第１の開口に面する導入口が形成されている。好ましくは、容器の平面視において、仕切部材は、第２の開口よりも第１の開口の近くに配置されている。 In a plan view of the container of the gas-liquid separator according to the present invention, the first opening and the second opening are preferably opposed to each other. The partition member preferably has a partition peripheral wall having a cylindrical shape. Preferably, in the plan view of the container, an introduction port facing the first opening is formed on one end side of the partition peripheral wall. Preferably, the partition member is disposed closer to the first opening than the second opening in a plan view of the container.
　この構成によれば、仕切周壁の他端側の外面と、容器の他端側の周壁の内面との距離を拡大させることができる。これにより、気液分離部において、導出室の上方に配置された空間の容積を拡大させることができる。そのため、導出室の容積を拡大させることができる。したがって、容器の内部に導入された液体を第２の開口から排出させるまでに、容器の内部において液体から気体をより効率よく分離させることができる。 According to this configuration, the distance between the outer surface on the other end side of the partition peripheral wall and the inner surface of the peripheral wall on the other end side of the container can be increased. Thereby, in the gas-liquid separation part, the volume of the space arranged above the outlet chamber can be enlarged. Therefore, the volume of the outlet chamber can be increased. Therefore, gas can be more efficiently separated from the liquid inside the container before the liquid introduced into the container is discharged from the second opening.
　本発明に従った気液分離器において、導出室を流通する溶液の流速は、第２の開口に向かって加速される。また、導入室から導出室に移動する溶液が、仕切部材の上端付近から底面に向かって落下することによって導出室に貯められた溶液の液面に衝突する場合には、液面の周りの空気が溶液に混合されることにより、溶液に多数の気泡が発生する。 In the gas-liquid separator according to the present invention, the flow rate of the solution flowing through the outlet chamber is accelerated toward the second opening. In addition, when the solution moving from the introduction chamber to the discharge chamber collides with the liquid level of the solution stored in the discharge chamber by dropping from the vicinity of the upper end of the partition member toward the bottom surface, the air around the liquid level Is mixed with the solution, a large number of bubbles are generated in the solution.
　しかしながら、本発明に従った気液分離器においては、仕切周壁および容器の一端側から離れた位置に第２の開口が配置されている。つまり、導入室から導出室に移動する溶液は、第２の開口から比較的離れた位置において液面と衝突する。そのため、液面に衝突することによって多数の気泡が発生する場合でも、気泡を含む溶液が第２の開口まで移動する間に、溶液から気泡を確実に分離させることができる。このようにして、本発明に従った気液分離器の構成によれば、第２の開口を通って容器の外部に気泡が排出されることを抑制することができる。 However, in the gas-liquid separator according to the present invention, the second opening is arranged at a position away from the partition peripheral wall and one end side of the container. That is, the solution that moves from the introduction chamber to the discharge chamber collides with the liquid surface at a position relatively distant from the second opening. Therefore, even when a large number of bubbles are generated by colliding with the liquid surface, the bubbles can be reliably separated from the solution while the solution containing the bubbles moves to the second opening. In this way, according to the configuration of the gas-liquid separator according to the present invention, it is possible to suppress discharge of bubbles to the outside of the container through the second opening.
　本発明に従った気液分離器において、好ましくは、仕切周壁の一端側が容器の周壁の一端側に固定されている。好ましくは、容器の平面視において、仕切周壁の一端側の外面から他端側の外面までの水平方向に沿った仕切周壁の寸法は、仕切周壁の他端側の外面から容器の他端側の周壁の内面までの水平方向に沿った距離よりも小さい。 In the gas-liquid separator according to the present invention, preferably, one end side of the partition peripheral wall is fixed to one end side of the peripheral wall of the container. Preferably, in the plan view of the container, the dimension of the partition peripheral wall along the horizontal direction from the outer surface on one end side of the partition peripheral wall to the outer surface on the other end side is from the outer surface on the other end side of the partition peripheral wall to the other end side of the container. It is smaller than the distance along the horizontal direction to the inner surface of the peripheral wall.
　この構成によれば、仕切部材と容器とを容易に一体に形成することができる。また、第１の開口に仕切部材をさらに近づけることができるとともに、仕切周壁と第２の開口とをさらに遠ざけることができる。これにより、気液分離部において、導出室の上方に配置された空間の容積を容器の幅方向および前後方向にさらに拡大させることができる。また、この構成によれば、導入室から導出室に移動する溶液は、第２の開口からより離れた位置において液面と衝突することができる。そのため、気泡を含む溶液が第２の開口まで移動する間に、溶液から気泡をより確実に分離させることができる。 According to this configuration, the partition member and the container can be easily formed integrally. In addition, the partition member can be further brought closer to the first opening, and the partition peripheral wall and the second opening can be further moved away from each other. Thereby, in the gas-liquid separation part, the volume of the space arranged above the outlet chamber can be further expanded in the width direction and the front-rear direction of the container. Further, according to this configuration, the solution moving from the introduction chamber to the discharge chamber can collide with the liquid surface at a position further away from the second opening. Therefore, the bubbles can be more reliably separated from the solution while the solution containing bubbles moves to the second opening.
　本発明に従った気液分離器は、好ましくは、導出室に溜められた液体の液位を所定の液位の範囲に維持するための液位調整部をさらに備えている。 The gas-liquid separator according to the present invention preferably further includes a liquid level adjusting unit for maintaining the liquid level of the liquid stored in the outlet chamber within a predetermined liquid level range.
　この構成によれば、所定の範囲において、空気が貯められた空間の容積の大きさを維持することができる。そのため、溶液に含まれる未溶解気体を溶液から効率よく分離させることを持続することができる。 According to this configuration, the volume of the space in which air is stored can be maintained within a predetermined range. Therefore, it is possible to continue efficiently separating undissolved gas contained in the solution from the solution.
　本発明に従ったオゾン水生成装置は、上記のいずれかの気液分離器と、オゾンを発生させるオゾン発生器と、容器に供給される液体に、オゾン発生器が発生させたオゾンを混合させる気液混合器とを備えていることが好ましい。 An ozone water generator according to the present invention mixes ozone generated by an ozone generator into any of the gas-liquid separators described above, an ozone generator that generates ozone, and a liquid supplied to a container. It is preferable to provide a gas-liquid mixer.
　本発明に従ったオゾン水生成装置は、排気弁を備えていなくても、容器の内部に導入された液体としてのオゾンが溶解した溶液を第２の開口から排出させるまでに、未溶解気体を溶液から効率よく分離させることができる。また、本発明に従ったオゾン水生成装置は、気液分離の性能の向上と、液体中のオゾン溶解率の向上とを図ることができる。そのため、本発明に従ったオゾン水生成装置は、オゾンの溶解率が比較的高い溶液を供給することができる。 Even if the ozone water generating device according to the present invention is not provided with an exhaust valve, an ozone gas as a liquid introduced into the container is discharged before the solution in which ozone is dissolved is discharged from the second opening. It can be efficiently separated from the solution. Moreover, the ozone water generator according to the present invention can improve the performance of gas-liquid separation and improve the ozone dissolution rate in the liquid. Therefore, the ozone water generating apparatus according to the present invention can supply a solution having a relatively high ozone dissolution rate.
　本発明に従った衛生器具用洗浄装置は、オゾン水生成装置を備えていることが好ましい。 The sanitary appliance cleaning device according to the present invention preferably includes an ozone water generator.

And a solution having a relatively high ozone dissolution rate can be supplied.

　以下、本発明の実施の形態を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　（第１実施形態）
　図１に、本発明に係る気液分離器を備えたオゾン水生成装置１００を示す。オゾン水生成装置１００は、オゾンが溶解した水を供給する装置である。オゾン水生成装置１００は、気体流路１１４と、液体流路１２１と、オゾン発生器１２０と、気液混合部の一例としてのエジェクタ１３０と、気液分離器の一例としての気液分離部１４０とを備えている。 (First embodiment)
FIG. 1 shows an ozone water generator 100 equipped with a gas-liquid separator according to the present invention. The ozone water generation apparatus 100 is an apparatus that supplies water in which ozone is dissolved. The ozone water generating apparatus 100 includes a gas channel 114, a liquid channel 121, an ozone generator 120, an ejector 130 as an example of a gas-liquid mixing unit, and a gas-liquid separation unit 140 as an example of a gas-liquid separator. And.
　オゾン水生成装置１００は、当該装置の外部から気体を導入する気体導入部１１０を備えている。気体導入部１１０は、管路１１１と逆止弁１１２とを有している。管路１１１の一端は、酸素または空気を貯蔵したガスボンベ（図示せず）等と接続している。ただし、管路１１１の一端は、大気圧に開放されていてもよい。なお、管路１１１と気体流路１１４と液体流路１２１とは、一般的な配管によって形成されており、図示しない管状部材によって形成されている。 The ozone water generation apparatus 100 includes a gas introduction unit 110 that introduces a gas from the outside of the apparatus. The gas introduction part 110 has a pipe line 111 and a check valve 112. One end of the pipe line 111 is connected to a gas cylinder (not shown) that stores oxygen or air. However, one end of the pipe line 111 may be opened to atmospheric pressure. In addition, the pipe line 111, the gas flow path 114, and the liquid flow path 121 are formed with general piping, and are formed with the tubular member which is not shown in figure.
　管路１１１の他端は、接続部１１３を介して気体流路１１４に接続されている。気体流路１１４は、気体状態のオゾンを流通させるためのものである。 The other end of the pipe line 111 is connected to the gas flow path 114 via the connection part 113. The gas flow path 114 is for circulating ozone in a gaseous state.
　なお、管路１１１には、オゾンガスを還元する機能を有するオゾンフィルタ（図示せず）が配置されていてもよい。オゾンフィルタは、例えば、オゾンを分解するための触媒が、格子状に構成された紙またはアルミニウムに付着されたもの等、一般的なオゾンフィルタである。 Note that an ozone filter (not shown) having a function of reducing ozone gas may be disposed in the pipe line 111. The ozone filter is a general ozone filter, for example, a catalyst for decomposing ozone attached to paper or aluminum configured in a lattice shape.
　オゾン発生器１２０は、気体状態のオゾンを生成し且つ生成したオゾンを気体流路１１４に供給する。気体導入部１１０によって導入された空気または酸素等の気体は、管路１１１と気体流路１１４とを通ってオゾン発生器１２０に導入される。オゾン発生器１２０は、金属電極によって形成されたオゾン発生素子（図示せず）を有している。オゾン発生素子は、導入された空気または酸素を材料にしてオゾンガスを発生させる。なお、オゾン発生器１２０の構成は、特に限定されず、気体流路１１４から導入される空気または酸素等の気体からオゾンガスを生成するように構成されていればよい。オゾン発生器１２０としては、一般的なオゾン発生器を用いることが可能である。 The ozone generator 120 generates gaseous ozone and supplies the generated ozone to the gas flow path 114. A gas such as air or oxygen introduced by the gas introduction unit 110 is introduced into the ozone generator 120 through the pipe 111 and the gas flow path 114. The ozone generator 120 has an ozone generating element (not shown) formed by a metal electrode. The ozone generating element generates ozone gas using the introduced air or oxygen as a material. In addition, the structure of the ozone generator 120 is not specifically limited, What is necessary is just to be comprised so that ozone gas may be produced | generated from gas, such as air introduced from the gas flow path 114, or oxygen. As the ozone generator 120, a general ozone generator can be used.
　オゾン水生成装置１００において、液体としての水は液体流路１２１を流通する。液体流路１２１は、オゾンが溶解される水を流通させる。オゾン水生成装置１００は、給水部１５０を備えている。オゾン水生成装置１００の使用者が図示しない水道蛇口を開放することにより、原水としての水道水が給水部１５０からオゾン水生成装置１００に供給される。ただし、原水は、水道水に限定されず、浄化もしくは精製された水であってもよい。 In the ozone water generating apparatus 100, water as a liquid flows through the liquid channel 121. The liquid channel 121 circulates water in which ozone is dissolved. The ozone water generating apparatus 100 includes a water supply unit 150. When the user of the ozone water generating apparatus 100 opens a water tap (not shown), tap water as raw water is supplied from the water supply unit 150 to the ozone water generating apparatus 100. However, the raw water is not limited to tap water, and may be purified or purified water.
　液体流路１２１は、給水部１５０に接続している。給水部１５０は、図示しない電磁弁を有している。給水部１５０は、オゾン水生成装置１００の本体（図示せず）の外部に配置されていてもよく、本体の内部に収容されていてもよい。給水部１５０の弁は、液体流路１２１のうちのエジェクタ１３０よりも水の流れ方向の上流の部分を開閉する。 The liquid channel 121 is connected to the water supply unit 150. The water supply unit 150 has a solenoid valve (not shown). The water supply part 150 may be arrange | positioned outside the main body (not shown) of the ozone water production | generation apparatus 100, and may be accommodated in the inside of a main body. The valve of the water supply unit 150 opens and closes a portion of the liquid channel 121 upstream of the ejector 130 in the water flow direction.
　オゾン水生成装置１００においては、気液混合部として、エジェクタ型のものが利用されている。気液混合部の一例としてのエジェクタ１３０は、液体流路１２１の一部を形成している。エジェクタ１３０には、気体の流入口１３３と液体の流入口１３１とオゾン水の流出口１３２とが形成されている。気体流路１１４の一端は、流入口１３３を介してエジェクタ１３０に接続されている。 In the ozone water generating apparatus 100, an ejector type is used as the gas-liquid mixing unit. An ejector 130 as an example of a gas-liquid mixing unit forms part of the liquid channel 121. The ejector 130 is formed with a gas inlet 133, a liquid inlet 131, and an ozone water outlet 132. One end of the gas flow path 114 is connected to the ejector 130 via the inflow port 133.
　オゾン発生器１２０から気体流路１１４に供給されるオゾンは、気体流路１１４の一端からエジェクタ１３０に導入される。エジェクタ１３０に導入されるオゾンは、液体流路１２１を流通する水に混合され、且つ、液体流路１２１の流れの圧力に基づいて水に溶解される。このようにして、エジェクタ１３０は、液体流路１２１を流通する水に、オゾン発生器１２０から気体流路１１４に供給される気体としてのオゾンを溶解させる。 Ozone supplied from the ozone generator 120 to the gas flow path 114 is introduced into the ejector 130 from one end of the gas flow path 114. The ozone introduced into the ejector 130 is mixed with water flowing through the liquid channel 121 and is dissolved in water based on the pressure of the flow in the liquid channel 121. In this way, the ejector 130 dissolves ozone as a gas supplied from the ozone generator 120 to the gas channel 114 in the water flowing through the liquid channel 121.
　エジェクタ１３０よりも、液体流路１２１を流通する水の流れ方向の下流には、気液分離部１４０が配置されている。気液分離部１４０は、液体流路１２１のうちのエジェクタ１３０よりも水の流れ方向の下流の一部を形成している。気液分離部１４０には、気体の流出口１４３とオゾン水の流入口１４１とオゾン水の流出口１４２とが形成されている。流出口１４３には、気体流路１１４の他端が接続されている。 The gas-liquid separator 140 is disposed downstream of the ejector 130 in the flow direction of the water flowing through the liquid channel 121. The gas-liquid separator 140 forms a part of the liquid flow path 121 downstream of the ejector 130 in the water flow direction. In the gas-liquid separator 140, a gas outlet 143, an ozone water inlet 141, and an ozone water outlet 142 are formed. The other end of the gas flow path 114 is connected to the outflow port 143.
　流入口１４１から気液分離部１４０の内部に流入したオゾン水には、オゾンの気泡が、水に完全に溶解しないまま残っている。気液分離部１４０において、オゾンの気泡と水中に含まれる空気等の気体とは、液体流路１２１を流通する水から分離された後に、流出口１４３から気体流路１１４に排出される。気液分離部１４０は、液体流路１２１を流通する水からオゾンの気泡を含む気体を分離させる。また、気液分離部１４０は、水から分離されたオゾンの一部を気体流路１１４の他端から気体流路１１４に排出する。 In the ozone water that has flowed into the gas-liquid separator 140 from the inlet 141, ozone bubbles remain without being completely dissolved in the water. In the gas-liquid separation unit 140, the bubbles of ozone and the gas such as air contained in the water are separated from the water flowing through the liquid channel 121 and then discharged from the outlet 143 to the gas channel 114. The gas-liquid separator 140 separates the gas containing ozone bubbles from the water flowing through the liquid channel 121. In addition, the gas-liquid separation unit 140 discharges a part of the ozone separated from the water from the other end of the gas channel 114 to the gas channel 114.
　図２に示すように、気液分離部１４０は、容器１０４と、容器１０４に収容された内筒１４７とを備えている。容器１０４と内筒１４７とは、例えば樹脂材料によって形成されている。容器１０４は、天井面１４６と、底面１４５と、周壁１４９とを有している。周壁１４９は、天井面１４６と底面１４５との間を上下方向に延びている。図２と図３とを参照するように、周壁１４９と内筒１４７とは、それぞれ略円筒形状を有している。天井面１４６と底面１４５とは、それぞれ略円盤形状を有している。 As shown in FIG. 2, the gas-liquid separation unit 140 includes a container 104 and an inner cylinder 147 accommodated in the container 104. The container 104 and the inner cylinder 147 are made of, for example, a resin material. The container 104 has a ceiling surface 146, a bottom surface 145, and a peripheral wall 149. The peripheral wall 149 extends vertically between the ceiling surface 146 and the bottom surface 145. As shown in FIG. 2 and FIG. 3, the peripheral wall 149 and the inner cylinder 147 each have a substantially cylindrical shape. The ceiling surface 146 and the bottom surface 145 each have a substantially disk shape.
　例えば、図２の左右方向または図３の左右方向のことを容器１０４の幅方向という。また、図２の上下方向は、鉛直上下方向と略一致している。 For example, the horizontal direction in FIG. 2 or the horizontal direction in FIG. 3 is referred to as the width direction of the container 104. In addition, the vertical direction in FIG. 2 substantially coincides with the vertical vertical direction.
　仕切部材の一例としての内筒１４７は、容器１０４の内部において容器１０４の幅方向の一端側に配置されている。図２に示すように、容器１０４の内部の左側に内筒１４７が配置されている。内筒１４７は、略円筒形状を持つ仕切周壁１４７ｂを有している。仕切周壁１４７ｂは、容器１０４の底面１４５から上方に向かって延びている。 The inner cylinder 147 as an example of a partition member is disposed inside the container 104 at one end side in the width direction of the container 104. As shown in FIG. 2, an inner cylinder 147 is arranged on the left side inside the container 104. The inner cylinder 147 has a partition peripheral wall 147b having a substantially cylindrical shape. The partition peripheral wall 147 b extends upward from the bottom surface 145 of the container 104.
　仕切周壁１４７ｂの上端面１４７ｃは、天井面１４６よりも下方に配置されている。上端面１４７ｃは、天井面１４６に面している。上端面１４７ｃが延びる方向は、天井面１４６および底面１４５が延びる方向と略平行な方向である。天井面１４６および底面１４５は、略水平方向に延びている。つまり、上端面１４７ｃの全体は、略水平方向から傾斜することなく、底面１４５に対して略同一位置に配置されている。 The upper end surface 147c of the partition peripheral wall 147b is disposed below the ceiling surface 146. The upper end surface 147c faces the ceiling surface 146. The direction in which the upper end surface 147c extends is a direction substantially parallel to the direction in which the ceiling surface 146 and the bottom surface 145 extend. The ceiling surface 146 and the bottom surface 145 extend in a substantially horizontal direction. That is, the entire upper end surface 147c is disposed at substantially the same position with respect to the bottom surface 145 without being inclined from the substantially horizontal direction.
　内筒１４７は、導入室４１と導出室４２とに容器１０４の内部を区画する。導入室４１は、容器１０４の外部から内部に導入された水が流通するための空間である。導出室４２は、容器１０４の内部から外部に導出される水が流通するための空間である。 The inner cylinder 147 partitions the inside of the container 104 into an introduction chamber 41 and an outlet chamber 42. The introduction chamber 41 is a space for circulating water introduced from the outside to the inside of the container 104. The lead-out chamber 42 is a space through which water led out from the inside of the container 104 flows.
　導入室４１の容積は、導出室４２の容積よりも小さい。導入室４１は、容器１０４の左側において、仕切周壁１４７ｂに囲まれた空間を含む。導出室４２は、容器１０４の周壁１４９の内面１４９ｓａと仕切周壁１４７ｂの外面とに囲まれた空間を含む。導入室４１と導出室４２とは、天井面１４６付近の空間の一部、つまり、仕切周壁１４７ｂの上端面１４７ｃと天井面１４６とに挟まれた空間によって互いに接続されている。仕切周壁１４７ｂの上端面１４７ｃと天井面１４６とに挟まれた空間は、導入室４１の一部であってもよく、導出室４２の一部であってもよく、または、後述する空間４３の一部であってもよい。 The volume of the introduction chamber 41 is smaller than the volume of the outlet chamber 42. The introduction chamber 41 includes a space surrounded by the partition peripheral wall 147 b on the left side of the container 104. The lead-out chamber 42 includes a space surrounded by the inner surface 149sa of the peripheral wall 149 of the container 104 and the outer surface of the partition peripheral wall 147b. The introduction chamber 41 and the lead-out chamber 42 are connected to each other by a part of the space near the ceiling surface 146, that is, a space sandwiched between the upper end surface 147c of the partition peripheral wall 147b and the ceiling surface 146. The space sandwiched between the upper end surface 147c of the partition peripheral wall 147b and the ceiling surface 146 may be a part of the introduction chamber 41, a part of the outlet chamber 42, or a space 43 to be described later. It may be a part.
　オゾン水の流入口１４１とオゾン水の流出口１４２とは、周壁１４９に形成されている。第１の開口の一例としての流入口１４１と、第２の開口の一例としての流出口１４２とは、内筒１４７の上端面１４７ｃよりも下方に配置されている。流入口１４１は、容器１０４の外部と導入室４１とを連通させる。上下方向に沿った流入口１４１の下端の位置は、底面１４５の位置と略一致している。 The ozone water inlet 141 and the ozone water outlet 142 are formed in the peripheral wall 149. An inflow port 141 as an example of the first opening and an outflow port 142 as an example of the second opening are disposed below the upper end surface 147 c of the inner cylinder 147. The inflow port 141 allows the outside of the container 104 to communicate with the introduction chamber 41. The position of the lower end of the inflow port 141 along the vertical direction is substantially coincident with the position of the bottom surface 145.
　一方、導出室４２と容器１０４の外部とは、流出口１４２を介して互いに連通する。上下方向に沿った流出口１４２の下端の位置は、底面１４５の位置と略一致している。 On the other hand, the outlet chamber 42 and the outside of the container 104 communicate with each other through the outflow port 142. The position of the lower end of the outflow port 142 along the vertical direction substantially matches the position of the bottom surface 145.
　容器１０４の上壁の一部には、筒状部１４４が形成されている。筒状部１４４は、空間４３の上方に配置されている。筒状部１４４の下端の開口は、気体の流出口１４３である。流出口１４３は、容器１０４の天井面１４６に形成されている。第３の開口の一例としての気体の流出口１４３は、流入口１４１および流出口１４２よりも上方に配置されている。導出室４２と容器１０４の外部とは、流出口１４３を介して連通する。詳細には、導出室４２の上方に配置された空間４３と容器１０４の外部とが、流出口１４３を介して互いに連通する。 A cylindrical portion 144 is formed on a part of the upper wall of the container 104. The cylindrical portion 144 is disposed above the space 43. The opening at the lower end of the cylindrical portion 144 is a gas outlet 143. The outlet 143 is formed on the ceiling surface 146 of the container 104. The gas outlet 143 as an example of the third opening is disposed above the inlet 141 and the outlet 142. The lead-out chamber 42 and the outside of the container 104 communicate with each other via the outflow port 143. Specifically, the space 43 disposed above the outlet chamber 42 and the outside of the container 104 communicate with each other via the outlet 143.
　筒状部１４４の上端から下端までは、気体流路１１４（図１参照）の一部を形成している。気体流路１１４の他端において、気体流路１１４と容器１０４の内部とは、流出口１４３によって連通されている（図１参照）。 A part of the gas flow path 114 (see FIG. 1) is formed from the upper end to the lower end of the cylindrical portion 144. At the other end of the gas flow path 114, the gas flow path 114 and the inside of the container 104 are communicated with each other by an outlet 143 (see FIG. 1).
　容器１０４の左側の周壁１４９にはノズル２１ｐが取り付けられている。ノズル２１ｐは、流入口１４１に挿入されている。容器１０４の右側の周壁１４９にはノズル２２ｐが取り付けられている。ノズル２１ｐと、ノズル２２ｐは、互いに略平行な方向であって、容器１０４の幅方向に延びている。 The nozzle 21p is attached to the left peripheral wall 149 of the container 104. The nozzle 21p is inserted into the inflow port 141. A nozzle 22 p is attached to the right peripheral wall 149 of the container 104. The nozzle 21p and the nozzle 22p extend in the width direction of the container 104 in directions substantially parallel to each other.
　ノズル２２ｐは、流出口１４２に挿入されている。ノズル２１ｐの内部とノズル２２ｐの内部とは、液体流路１２１の一部を形成している。なお、ノズル２１ｐとノズル２２ｐのいずれかまたは両方は、容器１０４と一体成型されていてもよい。 The nozzle 22p is inserted into the outflow port 142. The inside of the nozzle 21p and the inside of the nozzle 22p form a part of the liquid channel 121. One or both of the nozzle 21p and the nozzle 22p may be integrally formed with the container 104.
　図３に示すように、流入口１４１と流出口１４２とは、容器１０４の幅方向に沿って互いに対向するように周壁１４９に形成されている。つまり、容器１０４の平面視において、流入口１４１と流出口１４２とは、互いに対向している。 As shown in FIG. 3, the inflow port 141 and the outflow port 142 are formed in the peripheral wall 149 so as to face each other along the width direction of the container 104. That is, in the plan view of the container 104, the inflow port 141 and the outflow port 142 face each other.
　仕切周壁１４７ｂの一端側の外面が容器１０４の一端側の周壁１４９の内面１４９ｓａに固定されることにより、内筒１４７は、容器１０４に接触している。容器１０４の平面視において、仕切周壁１４７ｂの一端側の外面から他端側の外面までの水平方向に沿った仕切周壁１４７ｂの寸法Ｌ１は、仕切周壁１４７ｂの他端側の外面から容器１０４の他端側の周壁１４９の内面１４９ｓａまでの水平方向に沿った距離Ｌ２よりも小さい。このように、容器１０４の平面視において、内筒１４７は、流出口１４２よりも流入口１４１の近くに配置されている。 The outer surface on one end side of the partition peripheral wall 147 b is fixed to the inner surface 149 sa of the peripheral wall 149 on one end side of the container 104, so that the inner cylinder 147 is in contact with the container 104. In a plan view of the container 104, the dimensions L 1 of the partition wall 147b along the horizontal direction from one end side of the outer surface of the partition wall 147b to the outer surface of the other end, the container 104 from the other end of the outer surface of the partition wall 147b smaller than the distance L 2 along the horizontal direction to the inner surface 149sa the other end of the peripheral wall 149. Thus, the inner cylinder 147 is disposed closer to the inlet 141 than the outlet 142 in the plan view of the container 104.
　容器１０４の平面視において、仕切周壁１４７ｂの一端側には、流入口１４１に面する導入口１４７ａが形成されている。導入口１４７ａの口径と、流入口１４１に挿入された部分のノズル２１ｐの口径とは、略同一である。また、流入口１４１に挿入された部分のノズル２１ｐの端面は、導入口１４７ａを囲む仕切周壁１４７ｂの外面に接触している。 In the plan view of the container 104, an inlet 147a facing the inflow port 141 is formed on one end side of the partition peripheral wall 147b. The diameter of the introduction port 147a and the diameter of the nozzle 21p at the portion inserted into the inflow port 141 are substantially the same. Further, the end surface of the nozzle 21p at the portion inserted into the inflow port 141 is in contact with the outer surface of the partition peripheral wall 147b surrounding the introduction port 147a.
　このように、液体流路１２１は、ノズル２１ｐの内部と、仕切周壁１４７ｂの内側との間において連続している。導入室４１と容器１０４の外部とは、流入口１４１および導入口１４７ａを介して互いに連通する。 Thus, the liquid flow path 121 is continuous between the inside of the nozzle 21p and the inside of the partition peripheral wall 147b. The introduction chamber 41 and the outside of the container 104 communicate with each other via the inflow port 141 and the introduction port 147a.
　図２に示すように、容器１０４の内部には、気体を貯留する空間４３が形成されている。空間４３は、容器１０４の内部の溶液の液面と天井面１４６との間に形成されている。気液分離部１４０においては、内筒１４７が流出口１４２よりも流入口１４１の近くに配置されているため、空間４３のうち、導出室４２の上方に配置された部分の容積が比較的大きい。導入室４１と、導出室４２と、空間４３の一部とは、液体流路１２１の一部を形成している。なお、液体流路１２１の一部を形成する空間４３の一部は、導入室４１の一部と導出室４２の一部とを兼用する。 As shown in FIG. 2, a space 43 for storing gas is formed inside the container 104. The space 43 is formed between the liquid level of the solution inside the container 104 and the ceiling surface 146. In the gas-liquid separation unit 140, since the inner cylinder 147 is disposed closer to the inlet 141 than the outlet 142, the volume of the portion of the space 43 disposed above the outlet chamber 42 is relatively large. . The introduction chamber 41, the outlet chamber 42, and a part of the space 43 form a part of the liquid channel 121. A part of the space 43 that forms a part of the liquid flow path 121 serves as a part of the introduction chamber 41 and a part of the outlet chamber 42.
　気液分離部１４０は、気体流通制限部７０を備えている。気体流通制限部７０は、容器１０４の内部の溶液の液位を調整する液位調整部の一例である。気体流通制限部７０は、導出室４２のオゾン水の水位の変化に連動することによって流出口１４３を開閉する。気体流通制限部７０は、流出口１４３を開閉することにより、導出室４２に溜められたオゾン水の水位を所定の水位の範囲に維持する。 The gas-liquid separation unit 140 includes a gas flow restriction unit 70. The gas flow restriction unit 70 is an example of a liquid level adjusting unit that adjusts the liquid level of the solution inside the container 104. The gas flow restriction unit 70 opens and closes the outlet 143 by interlocking with the change in the water level of the ozone water in the outlet chamber 42. The gas flow restriction unit 70 opens and closes the outlet 143 to maintain the level of ozone water stored in the outlet chamber 42 within a predetermined water level.
　気体流通制限部７０は、フロート７１と、栓部７３とを有している。栓部７３は、ゴム等の弾性材料によって球体状に形成されている。 The gas flow restriction part 70 has a float 71 and a plug part 73. The plug portion 73 is formed in a spherical shape by an elastic material such as rubber.
　栓部７３の球の径は、流出口１４３の径よりも大きい。栓部７３は、流出口１４３の下方に配置されている。 The diameter of the sphere of the plug portion 73 is larger than the diameter of the outlet 143. The plug portion 73 is disposed below the outflow port 143.
　また、気体流通制限部７０は、フロートガイド７５と、容器１０４側の支持部７６と、フロート７１側の支持部７７とを有している。容器１０４側の支持部７６は、天井面１４６に固定されている。フロート７１側の支持部７７は、フロート７１の上面に固定されている。 Further, the gas flow restriction unit 70 includes a float guide 75, a support unit 76 on the container 104 side, and a support unit 77 on the float 71 side. The support portion 76 on the container 104 side is fixed to the ceiling surface 146. The support portion 77 on the float 71 side is fixed to the upper surface of the float 71.
　フロートガイド７５は、樹脂材料によって形成されたロッド状または板状の部材である。フロートガイド７５が支持部７６を中心に回転自在であるように、フロートガイド７５の一端は、支持部７６に取り付けられている。また、フロートガイド７５の中央部には、栓部７３が形成されている。フロートガイド７５の他端は、支持部７７に取り付けられている。 The float guide 75 is a rod-shaped or plate-shaped member formed of a resin material. One end of the float guide 75 is attached to the support portion 76 so that the float guide 75 is rotatable about the support portion 76. A plug portion 73 is formed at the center of the float guide 75. The other end of the float guide 75 is attached to the support portion 77.
　オゾン水の水位の変化に応じてフロート７１が上下に移動する場合に、フロートガイド７５が支持部７６を中心に回転する。このフロートガイド７５の回転に伴って、栓部７３が上下に移動する。 When the float 71 moves up and down according to the change in the ozone water level, the float guide 75 rotates around the support portion 76. As the float guide 75 rotates, the plug 73 moves up and down.
　次に、図１～図２を用いて、オゾン水生成装置１００の水の流れと、オゾンを含む気体の流れとを説明する。オゾン水生成装置１００において、液体としての水は、給水部１５０から液体流路１２１に供給される。液体流路１２１を流れる水は、流入口１３１からエジェクタ１３０の内部に流入する。エジェクタ１３０の内部を流通した水は、流出口１３２からエジェクタ１３０の外部に流出する。 Next, the flow of water in the ozone water generator 100 and the flow of gas containing ozone will be described with reference to FIGS. In the ozone water generating apparatus 100, water as a liquid is supplied from the water supply unit 150 to the liquid channel 121. Water flowing through the liquid flow path 121 flows into the ejector 130 from the inlet 131. The water that has circulated through the ejector 130 flows out of the ejector 130 from the outlet 132.
　エジェクタ１３０の内部には、オゾン発生器１２０が発生させた気体のオゾンが流入口１３３から流入する。流入口１３３から流入した気体のオゾンは、液体流路１２１としてエジェクタ１３０の内部を流通する水に混合される。水に混合されたオゾンの一部は、水流の圧力に基づいて水に溶解される。オゾンを含む水は、流出口１３２からエジェクタ１３０の外部に流出する。 The gaseous ozone generated by the ozone generator 120 flows into the ejector 130 from the inlet 133. The gaseous ozone flowing in from the inflow port 133 is mixed with water flowing through the ejector 130 as the liquid flow path 121. Part of the ozone mixed with water is dissolved in water based on the pressure of the water stream. Water containing ozone flows out of the ejector 130 from the outlet 132.
　流出口１３２からエジェクタ１３０の外部に流出したオゾンを含む水は、流入口１４１から気液分離部１４０の内部に流入する。図２に示すように、ノズル２１ｐの内部から容器１０４の内部に流入したオゾンを含む水は、仕切周壁１４７ｂの内面に沿って、底面１４５から上方に向かって導入室４１を流通する。導入室４１の上部に達した溶液は、仕切周壁１４７ｂの上端面１４７ｃと天井面１４６との間を移動した後に、下方に向かって導出室４２を流通する。導出室４２の下部のうちの底面１４５の近傍に達した溶液は、流出口１４２から容器１０４の外部に流出する。 Water containing ozone that has flowed out of the ejector 130 from the outlet 132 flows into the gas-liquid separator 140 from the inlet 141. As shown in FIG. 2, the water containing ozone that has flowed into the container 104 from the inside of the nozzle 21p flows through the introduction chamber 41 upward from the bottom surface 145 along the inner surface of the partition peripheral wall 147b. The solution reaching the upper portion of the introduction chamber 41 moves between the upper end surface 147c of the partition peripheral wall 147b and the ceiling surface 146, and then flows through the outlet chamber 42 downward. The solution that has reached the vicinity of the bottom surface 145 in the lower part of the outlet chamber 42 flows out of the container 104 from the outlet 142.
　溶液の気泡に含まれるオゾンまたは空気等の気体は、容器１０４の内部を流通する間に、溶液から分離される。このように、溶液の気泡に含まれるオゾンまたは空気等の気体が溶液から分離された水として、オゾンが水に溶解したオゾン水が生成される。オゾンが水に溶解したオゾン水は、流出口１４２からノズル２２ｐの内部に流出することにより、気液分離部１４０の外部に流出する。 Gas such as ozone or air contained in the bubbles of the solution is separated from the solution while flowing inside the container 104. Thus, ozone water in which ozone is dissolved in water is generated as water in which a gas such as ozone or air contained in the bubbles of the solution is separated from the solution. The ozone water in which ozone is dissolved in water flows out of the gas-liquid separation unit 140 by flowing out of the outlet port 142 into the nozzle 22p.
　一方、溶液から分離されたオゾンまたは空気等の気体は、容器１０４の内部を流通する間に、空間４３に集められる。空間４３に集められた気体は、気体流通制限部７０が流出口１４３を開放している場合に、流出口１４３から筒状部１４４の内部を流通することにより、気液分離部１４０の外部に排出される。 On the other hand, gas such as ozone or air separated from the solution is collected in the space 43 while circulating inside the container 104. When the gas flow restriction part 70 opens the outlet 143, the gas collected in the space 43 flows to the outside of the gas-liquid separation part 140 by flowing through the inside of the cylindrical part 144 from the outlet 143. Discharged.
　気液分離部１４０において水から分離された空気とオゾンの一部とは、流出口１４３から気体流路１１４に流出する（図１参照）。水に溶解されていないオゾンと空気とは、気体流路１１４に排出された後に流入口１３３からエジェクタ１３０の内部に再び流入する。エジェクタ１３０において水に溶解されなかったオゾンは、気体流路１１４と、エジェクタ１３０と気液分離部１４０との間に延びる液体流路１２１の一部とを循環する間に、液体流路１２１を流通する水に次第に溶解される。オゾンが溶解したオゾン水は、流出口１４２から気液分離部１４０の外部に排出された後に、吐水部１６０からオゾン水生成装置１００の外部に供給される。 The air and a part of ozone separated from water in the gas-liquid separator 140 flow out from the outlet 143 to the gas flow path 114 (see FIG. 1). Ozone and air that are not dissolved in water flow into the ejector 130 from the inlet 133 after being discharged to the gas flow path 114. The ozone not dissolved in the water in the ejector 130 circulates in the liquid flow path 121 while circulating through the gas flow path 114 and a part of the liquid flow path 121 extending between the ejector 130 and the gas-liquid separation unit 140. It is gradually dissolved in the circulating water. The ozone water in which ozone is dissolved is discharged from the outlet 142 to the outside of the gas-liquid separator 140 and then supplied from the water discharger 160 to the outside of the ozone water generator 100.
　図２に示すように、導出室４２に貯められたオゾン水の水位が所定の上限位に達する場合には、栓部７３が流出口１４３を下方から覆うことにより、栓部７３が流出口１４３を閉塞する。これにより、エジェクタ１３０の吸引の作動によって流入口１３３から管路１１１（いずれも図１参照）に至る空間と、接続部１１３（図１参照）から流出口１４３に至る空間とが負圧となるため、逆止弁１１２が開くことによってエジェクタ１３０に外気が流入する。その結果、気液分離部１４０の空間４３に外気が流れ込む。これにより、導出室４２の上方に配置された空間４３の容積が拡大するため、フロート７１の高さが下がることによって水位を自動的に調整することができる。 As shown in FIG. 2, when the water level of the ozone water stored in the outlet chamber 42 reaches a predetermined upper limit, the plug portion 73 covers the outlet 143 from below, so that the plug 73 becomes the outlet 143. Occlude. As a result, the space from the inlet 133 to the pipe 111 (both see FIG. 1) and the space from the connecting portion 113 (see FIG. 1) to the outlet 143 become negative pressure due to the suction of the ejector 130. Therefore, outside air flows into the ejector 130 when the check valve 112 is opened. As a result, outside air flows into the space 43 of the gas-liquid separator 140. Thereby, since the volume of the space 43 arranged above the outlet chamber 42 is enlarged, the water level can be automatically adjusted by reducing the height of the float 71.
　以上のように、気液分離部１４０は、容器１０４と内筒１４７とを備えている。容器１０４は、天井面１４６と、底面１４５と、周壁１４９とを有している。周壁１４９は、天井面１４６と底面１４５との間を上下方向に延びている。内筒１４７は、容器１０４の内部において底面１４５から上方に向かって延びている。内筒１４７は、容器１０４の外部から内部に導入された溶液が流通するための導入室４１と、容器１０４の内部から外部に導出される溶液が流通するための導出室４２とに容器１０４の内部を区画する。導入室４１の容積は、導出室４２の容積よりも小さい。 As described above, the gas-liquid separation unit 140 includes the container 104 and the inner cylinder 147. The container 104 has a ceiling surface 146, a bottom surface 145, and a peripheral wall 149. The peripheral wall 149 extends vertically between the ceiling surface 146 and the bottom surface 145. The inner cylinder 147 extends upward from the bottom surface 145 inside the container 104. The inner cylinder 147 is connected to the introduction chamber 41 through which the solution introduced from the outside of the container 104 flows and the outlet chamber 42 through which the solution led out from the inside of the container 104 flows. Comparting the interior. The volume of the introduction chamber 41 is smaller than the volume of the outlet chamber 42.
　周壁１４９には、流入口１４１と流出口１４２とが形成されている。流入口１４１は、容器１０４の外部と導入室４１とを連通させる。流出口１４２は、容器１０４の外部と導出室４２とを連通させる。容器１０４には、気体の流出口１４３が形成されている。流出口１４３は、流入口１４１および流出口１４２よりも上方に配置され、且つ、導出室４２と容器１０４の外部とを連通させる。また、容器１０４の内部には、導出室４２の上方に配置され、且つ、気体を貯留する空間４３が形成されている。 An inlet 141 and an outlet 142 are formed in the peripheral wall 149. The inflow port 141 allows the outside of the container 104 to communicate with the introduction chamber 41. The outflow port 142 allows the outside of the container 104 to communicate with the outlet chamber 42. A gas outlet 143 is formed in the container 104. The outflow port 143 is disposed above the inflow port 141 and the outflow port 142, and communicates the outlet chamber 42 with the outside of the container 104. In addition, a space 43 that is disposed above the outlet chamber 42 and stores gas is formed inside the container 104.
　気液分離部１４０によれば、気体が貯留される空間４３が導出室４２の上方に配置されている。これにより、容器１０４の外部から導入室４１に流入した溶液が、気体が貯留された空間４３を通過する際に、溶液が気体に容易に触れることができるため、溶液に含まれる未溶解気体を溶液から効率よく分離させることができる。また、気体が貯留される空間４３が導出室４２の上方に配置されていることにより、流入口１４１から導入室４１に勢いよく溶液が流入する場合でも、流出口１４３から溶液が噴出することを防止することができる。 According to the gas-liquid separation unit 140, the space 43 in which gas is stored is disposed above the outlet chamber 42. Thereby, when the solution flowing into the introduction chamber 41 from the outside of the container 104 passes through the space 43 in which the gas is stored, the solution can easily come into contact with the gas. It can be efficiently separated from the solution. Further, since the space 43 in which the gas is stored is disposed above the outlet chamber 42, the solution can be ejected from the outlet 143 even when the solution flows into the inlet chamber 41 from the inlet 141. Can be prevented.
　また、気液分離部１４０によれば、導入室４１の容積が導出室４２の容積よりも小さいことにより、導入室４１から導出室４２に移動した溶液の流速は、導出室４２において減速される。そのため、導出室４２を流れる溶液に含まれる未溶解の気体が、溶液とともに、流出口１４２を通って容器の外部に排出されることを抑制することができる。 Further, according to the gas-liquid separation unit 140, the flow rate of the solution that has moved from the introduction chamber 41 to the lead-out chamber 42 is decelerated in the lead-out chamber 42 because the volume of the introduction chamber 41 is smaller than the volume of the lead-out chamber 42. . Therefore, it is possible to suppress the undissolved gas contained in the solution flowing through the outlet chamber 42 from being discharged to the outside of the container through the outlet port 142 together with the solution.
　このように、気液分離部１４０によれば、容器１０４の内部に導入された溶液を流出口１４２から排出させるまでに、容器１０４の内部において溶液から気体を効率よく分離させることができる。また、気液分離部１４０は、排気弁を備えておらず、比較的簡易な構成を有している。 As described above, according to the gas-liquid separation unit 140, the gas can be efficiently separated from the solution inside the container 104 before the solution introduced into the container 104 is discharged from the outlet 142. The gas-liquid separation unit 140 does not include an exhaust valve and has a relatively simple configuration.
　気液分離部１４０の容器１０４の平面視において、流入口１４１と流出口１４２とは、互いに対向している。内筒１４７は、筒形状を持つ仕切周壁１４７ｂを有している。容器１０４の平面視において、仕切周壁１４７ｂの一端側には、流入口１４１に面する導入口１４７ａが形成されている。容器１０４の平面視において、内筒１４７は、流出口１４２よりも流入口１４１の近くに配置されている。 In the plan view of the container 104 of the gas-liquid separator 140, the inflow port 141 and the outflow port 142 face each other. The inner cylinder 147 has a partition peripheral wall 147b having a cylindrical shape. In the plan view of the container 104, an inlet 147a facing the inflow port 141 is formed on one end side of the partition peripheral wall 147b. In the plan view of the container 104, the inner cylinder 147 is disposed closer to the inlet 141 than the outlet 142.
　この構成によれば、仕切周壁の他端側の外面と、容器の他端側の周壁の内面との距離を拡大させることができる。これにより、気液分離部１４０において、導出室４２の上方に配置された空間４３の容積を容器１０４の幅方向および前後方向に拡大させることができる。したがって、容器１０４の内部に導入された溶液を流出口１４２から排出させるまでに、容器１０４の内部において溶液から気体をより効率よく分離させることができる。 According to this configuration, the distance between the outer surface on the other end side of the partition peripheral wall and the inner surface of the peripheral wall on the other end side of the container can be increased. Thereby, in the gas-liquid separation part 140, the volume of the space 43 arrange | positioned above the derivation | leading-out chamber 42 can be expanded in the width direction of the container 104, and the front-back direction. Therefore, the gas can be more efficiently separated from the solution inside the container 104 before the solution introduced into the container 104 is discharged from the outlet 142.
　気液分離部１４０において、導出室４２を流通する溶液の流速は、流出口１４２に向かって加速される。また、導入室４１から導出室４２に移動する溶液が、内筒１４７の上端付近から底面１４５に向かって落下することによって導出室４２に貯められた溶液の液面に衝突する場合には、液面の周りの空気が溶液に混合されることにより、溶液に多数の気泡が発生する。 In the gas-liquid separator 140, the flow rate of the solution flowing through the outlet chamber 42 is accelerated toward the outlet 142. In addition, when the solution moving from the introduction chamber 41 to the discharge chamber 42 falls from the vicinity of the upper end of the inner cylinder 147 toward the bottom surface 145 and collides with the liquid level of the solution stored in the discharge chamber 42, As the air around the surface is mixed with the solution, a large number of bubbles are generated in the solution.
　しかしながら、気液分離部１４０においては、仕切周壁１４７ｂおよび容器１０４の一端側から離れた位置に流出口１４２が配置されている。つまり、導入室４１から導出室４２に移動する溶液は、流出口１４２から比較的離れた位置において液面と衝突する。そのため、液面に衝突することによって多数の気泡が発生する場合でも、気泡を含む溶液が流出口１４２まで移動する間に、溶液から気泡を確実に分離させることができる。このようにして、気液分離部１４０の構成によれば、流出口１４２を通って容器１０４の外部に気泡が排出されることを抑制することができる。 However, in the gas-liquid separation unit 140, the outflow port 142 is disposed at a position away from the partition peripheral wall 147 b and the one end side of the container 104. That is, the solution that moves from the introduction chamber 41 to the outlet chamber 42 collides with the liquid level at a position relatively away from the outlet 142. Therefore, even when many bubbles are generated by colliding with the liquid surface, the bubbles can be reliably separated from the solution while the solution containing the bubbles moves to the outflow port 142. In this way, according to the configuration of the gas-liquid separation unit 140, it is possible to prevent bubbles from being discharged to the outside of the container 104 through the outflow port 142.
　気液分離部１４０において、仕切周壁１４７ｂの一端側の外面は、容器１０４の一端側の周壁１４９の内面に固定されている。容器１０４の平面視において、仕切周壁１４７ｂの一端側の外面から他端側の外面までの水平方向に沿った仕切周壁１４７ｂの寸法Ｌ１は、仕切周壁１４７ｂの他端側の外面から容器１０４の他端側の周壁１４９の内面１４９ｓａまでの水平方向に沿った距離Ｌ２よりも小さい。 In the gas-liquid separator 140, the outer surface on one end side of the partition peripheral wall 147 b is fixed to the inner surface of the peripheral wall 149 on one end side of the container 104. In a plan view of the container 104, the dimensions L 1 of the partition wall 147b along the horizontal direction from one end side of the outer surface of the partition wall 147b to the outer surface of the other end, the container 104 from the other end of the outer surface of the partition wall 147b smaller than the distance L 2 along the horizontal direction to the inner surface 149sa the other end of the peripheral wall 149.
　この構成によれば、内筒１４７と容器１０４とを容易に一体に形成することができる。また、流入口１４１に内筒１４７をさらに近づけることができるとともに、内筒１４７の仕切周壁１４７ｂと流出口１４２とをさらに遠ざけることができる。これにより、気液分離部１４０において、導出室４２の上方に配置された空間４３の容積を容器１０４の幅方向および前後方向にさらに拡大させることができる。また、この構成によれば、導入室４１から導出室４２に移動する溶液は、流出口１４２からより離れた位置において液面と衝突することができる。そのため、気泡を含む溶液が流出口１４２まで移動する間に、溶液から気泡をより確実に分離させることができる。 According to this configuration, the inner cylinder 147 and the container 104 can be easily formed integrally. In addition, the inner cylinder 147 can be brought closer to the inflow port 141, and the partition peripheral wall 147 b of the inner cylinder 147 and the outflow port 142 can be further away. Thereby, in the gas-liquid separator 140, the volume of the space 43 disposed above the outlet chamber 42 can be further expanded in the width direction and the front-rear direction of the container 104. Further, according to this configuration, the solution moving from the introduction chamber 41 to the outlet chamber 42 can collide with the liquid surface at a position further away from the outflow port 142. Therefore, the bubbles can be more reliably separated from the solution while the solution containing the bubbles moves to the outlet 142.
　気液分離部１４０は、導出室４２に溜められたオゾン水の水位を所定の水位の範囲に維持するための気体流通制限部７０を備えている。 The gas-liquid separation unit 140 includes a gas flow restriction unit 70 for maintaining the water level of ozone water stored in the outlet chamber 42 within a predetermined water level range.
　この構成によれば、所定の範囲において、空気が貯められた空間４３の容積の大きさを維持することができる。そのため、溶液に含まれる未溶解気体を溶液から効率よく分離させることを持続することができる。 According to this configuration, the volume of the space 43 in which air is stored can be maintained within a predetermined range. Therefore, it is possible to continue efficiently separating undissolved gas contained in the solution from the solution.
　オゾン水生成装置１００は、気液分離部１４０と、オゾンを発生させるオゾン発生器１２０と、容器１０４に供給される水に、オゾン発生器１２０が発生させたオゾンを混合させるエジェクタ１３０とを備えている。 The ozone water generator 100 includes a gas-liquid separator 140, an ozone generator 120 that generates ozone, and an ejector 130 that mixes the ozone supplied by the ozone generator 120 with the water supplied to the container 104. ing.
　オゾン水生成装置１００は、排気弁を備えていなくても、容器１０４の内部に導入された液体としてのオゾン水を流出口１４２から排出させるまでに、未溶解気体をオゾン水から効率よく分離させることができる。また、オゾン水生成装置１００は、気液分離の性能の向上と、溶液中のオゾン溶解率の向上とを図ることができる。そのため、オゾン水生成装置１００は、オゾンの溶解率が比較的高い溶液を供給することができる。 Even if the ozone water generating apparatus 100 does not include an exhaust valve, the ozone water as the liquid introduced into the container 104 is efficiently separated from the ozone water before the ozone water is discharged from the outlet 142. be able to. Moreover, the ozone water production | generation apparatus 100 can aim at the improvement of the performance of gas-liquid separation, and the improvement of the ozone dissolution rate in a solution. Therefore, the ozone water generating apparatus 100 can supply a solution having a relatively high ozone dissolution rate.

The direction in which the nozzle 21p extends and the direction in which the nozzle 22p extends are not limited to being substantially horizontal. However, it is preferable that the nozzle 21p is attached to the container 104 so that the solution flows from the inside of the nozzle 21p into the container 104 in a substantially horizontal direction. The nozzle 22p is preferably attached to the container 104 so that the solution flows out from the inside of the container 104 into the nozzle 22p in a substantially horizontal direction.

Further, the nozzle 21p may pass through the inflow port 141 and may be partially accommodated in the introduction port 147a. Alternatively, the end surface of the nozzle 21p may be attached to the outer surface 149sb of the peripheral wall 149 so as to contact the outer surface 149sb of the peripheral wall 149 surrounding the inflow port 141. Similarly, the end surface of the nozzle 22p may be attached to the outer surface 149sb of the peripheral wall 149 so as to contact the outer surface 149sb of the peripheral wall 149 surrounding the outflow port 142.
　流出口１４３は、天井面１４６ではなく、容器１０４の他端側の周壁１４９に形成されていてもよい。 The outlet 143 may be formed not on the ceiling surface 146 but on the peripheral wall 149 on the other end side of the container 104.
　気体流通制限部７０は、図２に示す構成を備えていることに限定されない。気体流通制限部７０は、例えば容器１０４においての流出口１４３の位置に応じて、容器１０４側の支持部が周壁１４９に取り付けられていてもよい。 The gas flow restriction unit 70 is not limited to having the configuration shown in FIG. In the gas flow restriction unit 70, for example, the support unit on the container 104 side may be attached to the peripheral wall 149 according to the position of the outlet 143 in the container 104.
　なお、気体導入部１１０は、オゾン水生成装置１００の外部から内部に気体を導入させることが可能であるように構成されていればよい。例えば、気体導入部１１０の構成は、逆止弁１１２の代わりにオゾン発生器１２０に供給される気体量を制御することが可能な開閉バルブまたは電磁弁等を備えていてもよい。あるいは、気体導入部１１０は、逆止弁１１２を備えていなくてもよく、接続部１１３に三方向弁が配置されたような構成であってもよい。この三方向弁は、例えば、電子的に制御されるものであって、図示しない制御部によって制御される。 In addition, the gas introduction part 110 should just be comprised so that gas can be introduce | transduced into the inside from the outside of the ozone water production | generation apparatus 100.

For example, the configuration of the gas introduction unit 110 may include an on-off valve or an electromagnetic valve that can control the amount of gas supplied to the ozone generator 120 instead of the check valve 112. Alternatively, the gas introduction unit 110 may not include the check valve 112 and may have a configuration in which a three-way valve is arranged at the connection unit 113.

Below, the ozone water generating apparatus which concerns on 2nd Embodiment is demonstrated using FIG. In addition, below, the same code | symbol is attached | subjected to the structure which has a function similar to the structure of the ozone water generating apparatus 100 which concerns on 1st Embodiment, and the description is abbreviate | omitted.
　以下に説明するように、第２実施形態に係るオゾン水生成装置が第１実施形態に係るオゾン水生成装置１００と異なる点は、第２実施形態に係るオゾン水生成装置は、気液分離部１４０の代わりに、気液分離部２４０を備えている。 As will be described below, the ozone water generating device according to the second embodiment is different from the ozone water generating device 100 according to the first embodiment in that the ozone water generating device according to the second embodiment is a gas-liquid separator. Instead of 140, a gas-liquid separator 240 is provided.
　図４に示すように、気液分離部２４０は、容器２０４と、容器２０４に収容された内筒２４７とを備えている。容器２０４は、周壁２４９を有している。周壁２４９と内筒２４７とは、それぞれ略長方形状を有している。図４には図示されていないが、容器２０４は、天井面と底面とを有している。容器２０４の天井面と底面とは、それぞれ略長方形状を有している。周壁２４９は、天井面と底面との間を上下方向に延びている。 As shown in FIG. 4, the gas-liquid separation unit 240 includes a container 204 and an inner cylinder 247 accommodated in the container 204. The container 204 has a peripheral wall 249. The peripheral wall 249 and the inner cylinder 247 each have a substantially rectangular shape. Although not shown in FIG. 4, the container 204 has a ceiling surface and a bottom surface. Each of the ceiling surface and the bottom surface of the container 204 has a substantially rectangular shape. The peripheral wall 249 extends in the vertical direction between the ceiling surface and the bottom surface.
　仕切部材の一例としての内筒２４７は、容器２０４の内部において容器２０４の幅方向の一端側に配置されている。内筒２４７は、容器２０４の内部の左側に配置されている。内筒２４７は、略筒形状を持つ仕切周壁２４７ｂを有している。仕切周壁２４７ｂの断面は、略長方形状を有している。仕切周壁２４７ｂは、容器２０４の底面から上方に向かって延びている。容器２０４の天井面に面する仕切周壁２４７ｂの上端面（図示せず）は、天井面よりも下方に配置されている。 The inner cylinder 247 as an example of a partition member is disposed on one end side in the width direction of the container 204 inside the container 204. The inner cylinder 247 is disposed on the left side inside the container 204. The inner cylinder 247 has a partition peripheral wall 247b having a substantially cylindrical shape. The cross section of the partition peripheral wall 247b has a substantially rectangular shape. The partition peripheral wall 247 b extends upward from the bottom surface of the container 204. An upper end surface (not shown) of the partition peripheral wall 247b facing the ceiling surface of the container 204 is disposed below the ceiling surface.
　内筒２４７は、導入室４１と導出室４２とに容器２０４の内部を区画する。導入室４１は、容器２０４の左側において、仕切周壁２４７ｂに囲まれた空間を含む。導出室４２は、容器２０４の周壁２４９の内面２４９ｓａと仕切周壁２４７ｂの外面とに囲まれた空間を含む。導入室４１と導出室４２とは、容器２０４の天井面付近の空間の一部、つまり、仕切周壁２４７ｂの上端面と天井面とに挟まれた空間によって互いに接続されている。 The inner cylinder 247 partitions the inside of the container 204 into an introduction chamber 41 and an outlet chamber 42. The introduction chamber 41 includes a space surrounded by the partition peripheral wall 247 b on the left side of the container 204. The lead-out chamber 42 includes a space surrounded by the inner surface 249sa of the peripheral wall 249 of the container 204 and the outer surface of the partition peripheral wall 247b. The introduction chamber 41 and the lead-out chamber 42 are connected to each other by a part of the space near the ceiling surface of the container 204, that is, a space sandwiched between the upper end surface of the partition peripheral wall 247b and the ceiling surface.
　オゾン水の流入口２４１とオゾン水の流出口２４２とは、周壁２４９に形成されている。第１の開口の一例としての流入口２４１と、第２の開口の一例としての流出口２４２とは、内筒２４７の上端面よりも下方に配置されている。流入口２４１は、容器２０４の外部と導入室４１とを連通させる。上下方向に沿った流入口２４１の下端の位置は、容器２０４の底面の位置と略一致している。一方、導出室４２と容器２０４の外部とは、流出口２４２を介して互いに連通する。上下方向に沿った流出口２４２の下端の位置は、容器２０４の底面の位置と略一致している。 The ozone water inlet 241 and the ozone water outlet 242 are formed on the peripheral wall 249. An inflow port 241 as an example of the first opening and an outflow port 242 as an example of the second opening are disposed below the upper end surface of the inner cylinder 247. The inflow port 241 allows the outside of the container 204 to communicate with the introduction chamber 41. The position of the lower end of the inflow port 241 along the vertical direction substantially coincides with the position of the bottom surface of the container 204. On the other hand, the outlet chamber 42 and the outside of the container 204 communicate with each other via the outflow port 242. The position of the lower end of the outflow port 242 along the vertical direction substantially matches the position of the bottom surface of the container 204.
　なお、気液分離部２４０において、第３の開口としての気体の流出口（図示せず）は、第１実施形態に係るオゾン水生成装置１００の気液分離部１４０（図２参照）と同様に、容器２０４の上壁に形成されている。 In the gas-liquid separator 240, the gas outlet (not shown) as the third opening is the same as the gas-liquid separator 140 (see FIG. 2) of the ozone water generator 100 according to the first embodiment. In addition, it is formed on the upper wall of the container 204.
　容器２０４の左側の周壁２４９にはノズル２３ｐが取り付けられている。ノズル２３ｐは、後述する導入口２４７ａに挿入されている。容器２０４の右側の周壁２４９にはノズル２４ｐが取り付けられている。ノズル２３ｐと、ノズル２４ｐは、互いに略平行な方向であって、容器２０４の幅方向に延びている。 The nozzle 23p is attached to the left peripheral wall 249 of the container 204. The nozzle 23p is inserted into an introduction port 247a described later. A nozzle 24 p is attached to the right peripheral wall 249 of the container 204. The nozzle 23p and the nozzle 24p extend in the width direction of the container 204 in directions substantially parallel to each other.
　ノズル２４ｐは、流出口２４２に挿入されている。ノズル２３ｐの内部とノズル２４ｐの内部とは、液体流路１２１の一部を形成している。なお、ノズル２３ｐとノズル２４ｐのいずれかまたは両方は、容器２０４と一体成型されていてもよい。 The nozzle 24p is inserted into the outlet 242. The inside of the nozzle 23p and the inside of the nozzle 24p form a part of the liquid channel 121. One or both of the nozzle 23p and the nozzle 24p may be integrally formed with the container 204.
　流入口２４１と流出口２４２とは、容器２０４の幅方向に沿って互いに対向するように周壁２４９に形成されている。仕切周壁２４７ｂの一端側の外面が容器２０４の一端側の周壁２４９に固定されることにより、内筒２４７は、容器２０４に接触している。容器２０４の平面視において、仕切周壁２４７ｂの一端側の外面から他端側の外面までの水平方向に沿った仕切周壁２４７ｂの寸法Ｌ３は、仕切周壁２４７ｂの他端側の外面から容器２０４の他端側の周壁２４９の内面２４９ｓａまでの水平方向に沿った距離Ｌ４よりも小さい。このように、容器２０４の平面視において、内筒２４７は、流出口２４２よりも流入口２４１の近くに配置されている。 The inflow port 241 and the outflow port 242 are formed on the peripheral wall 249 so as to face each other along the width direction of the container 204. The outer surface on one end side of the partition peripheral wall 247 b is fixed to the peripheral wall 249 on one end side of the container 204, so that the inner cylinder 247 is in contact with the container 204. In a plan view of the container 204, the partition wall 247b dimension L 3 of along the horizontal direction from the outer surface of one end side of the partition wall 247b to the outer surface of the other end, the container 204 from the outer surface of the other end side of the partition wall 247b smaller than the distance L 4 along the horizontal direction to the inner surface 249sa the other end of the peripheral wall 249. Thus, the inner cylinder 247 is disposed closer to the inlet 241 than the outlet 242 in the plan view of the container 204.
　容器２０４の平面視において、仕切周壁２４７ｂの一端側には、導入口２４７ａが形成されている。仕切周壁２４７ｂの一端側の外面は、容器２０４の一端側の周壁２４９の外面２４９ｓｂと連続している。導入口２４７ａが流入口２４１に含まれていることにより、導入口２４７ａと流入口２４１とは互いに面している。導入口２４７ａの口径と、導入口２４７ａに挿入された部分のノズル２３ｐの口径とは、略同一である。ノズル２３ｐは、導入口２４７ａに挿入された部分のノズル２３ｐの端面が、導入口２４７ａを囲む仕切周壁２４７ｂの内面と連続するように、内筒２４７に取り付けられている。 In the plan view of the container 204, an inlet 247a is formed on one end side of the partition peripheral wall 247b. The outer surface on one end side of the partition peripheral wall 247 b is continuous with the outer surface 249 sb of the peripheral wall 249 on one end side of the container 204. Since the introduction port 247a is included in the inflow port 241, the introduction port 247a and the inflow port 241 face each other. The diameter of the introduction port 247a and the diameter of the nozzle 23p in the portion inserted into the introduction port 247a are substantially the same. The nozzle 23p is attached to the inner cylinder 247 so that the end surface of the nozzle 23p in the portion inserted into the introduction port 247a is continuous with the inner surface of the partition peripheral wall 247b surrounding the introduction port 247a.
　図４には図示されていないが、気液分離部２４０において、気液分離部１４０（図２参照）と同様に、導出室４２の上方には、気体を貯留する空間が形成されている。また、気液分離部１４０と同様に、気液分離部２４０は、導出室４２のオゾン水の水位に連動することによって気体の流出口を開閉する気体流通制限部を備えている。 Although not shown in FIG. 4, in the gas-liquid separator 240, a space for storing gas is formed above the outlet chamber 42, similarly to the gas-liquid separator 140 (see FIG. 2). Similarly to the gas-liquid separation unit 140, the gas-liquid separation unit 240 includes a gas flow restriction unit that opens and closes the gas outlet by interlocking with the ozone water level in the outlet chamber 42.
　以上のように構成された気液分離部２４０は、第１実施形態に係るオゾン水生成装置１００の気液分離部１４０と同様の作用効果を得ることができる。また、気液分離部２４０を備えたオゾン水生成装置は、第１実施形態に係るオゾン水生成装置１００と同様の作用効果を得ることができる。 The gas-liquid separator 240 configured as described above can obtain the same functions and effects as those of the gas-liquid separator 140 of the ozone water generator 100 according to the first embodiment. Moreover, the ozone water generating apparatus provided with the gas-liquid separation part 240 can obtain the same effect as the ozone water generating apparatus 100 according to the first embodiment.
　なお、気液分離部２４０において、溶液の流入口２４１と気体の流出口とは、容器２０４の平面視において、周壁２４９の水平断面が形成する略長方形の対角線上に配置されていてもよい。 In the gas-liquid separation unit 240, the solution inflow port 241 and the gas outflow port may be arranged on a substantially rectangular diagonal line formed by the horizontal cross section of the peripheral wall 249 in a plan view of the container 204.
　第１実施形態に係るオゾン水生成装置１００と第２実施形態に係るオゾン水生成装置とのうち、例えばオゾン水生成装置１００は、衛生器具用洗浄装置に用いることができる。衛生器具には、例えば、便所、洗面所、または、浴室に用いられた大小便器、手洗い器、洗面器、または、浴槽等が含まれる。つまり、オゾン水生成装置１００を備えた衛生器具用洗浄装置は、例えば、便所、洗面所、もしくは、浴室に用いられる器具、または、便所、洗面所、もしくは、浴室を洗浄するための装置である。 Among the ozone water generating apparatus 100 according to the first embodiment and the ozone water generating apparatus according to the second embodiment, for example, the ozone water generating apparatus 100 can be used for a sanitary appliance cleaning apparatus. Sanitary ware includes, for example, toilets, toilets, large and small urinals used in bathrooms, hand-washers, wash-basins, bathtubs, and the like. That is, the sanitary appliance cleaning device provided with the ozone water generating device 100 is, for example, a device used for a toilet, a toilet, or a bathroom, or a device for cleaning a toilet, a toilet, or a bathroom. .
　例えば、図５に示すように、小便器９０１，９０２，９０３を洗浄するための衛生器具用洗浄装置９５０が便所９００に設置されている。便所９００は、衛生器具設備の一例である。衛生器具用洗浄装置９５０は、小便器９０１，９０２，９０３を含む便器に水を供給するための配管９１０に接続されている。衛生器具用洗浄装置９５０は、オゾン水生成装置１００を備えている。配管９１０を流通する水が衛生器具用洗浄装置９５０を通過するときに水にオゾンが溶解されることにより、オゾン水が生成される。衛生器具用洗浄装置９５０を通過した後に配管９１０を流通するオゾン水は、小便器９０１，９０２，９０３を含む便器に供給される。 For example, as shown in FIG. 5, a sanitary appliance cleaning device 950 for cleaning the urinals 901, 902, and 903 is installed in the toilet 900. The toilet 900 is an example of a sanitary equipment facility.
