　例えば経年劣化または破損等によって、ガス返送路からガス漏れが発生する場合には、数百ｐｐｍを超える高濃度のオゾンガスが大気中に放出される危険がある。そのため、オゾンガスの漏出によって環境に悪影響が及ぼされるという問題がある。 If there is a gas leak from the gas return path due to, for example, aging or damage, there is a risk that ozone gas with a high concentration exceeding several hundred ppm will be released into the atmosphere. Therefore, there is a problem that the ozone gas leaks adversely affects the environment.
　そこで、本発明の目的は、オゾン水生成装置であって、オゾンガスの漏出によって環境に悪影響が及ぼされることを防止することが可能な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を提供することである。 SUMMARY OF THE INVENTION An object of the present invention is to provide an ozone water generator, which can prevent an adverse effect on the environment due to leakage of ozone gas, and a sanitary equipment cleaning device equipped with the ozone water generator. It is to be.
　本発明に従ったオゾン水生成装置は、気体流路と、液体流路と、オゾン発生部と、気液混合部と、気液分離部と、筐体と、オゾン検知部と、制御部とを備えている。気体流路は、気体状態のオゾンを流通させる。液体流路は、オゾンが溶解される水を流通させる。 An ozone water generating device according to the present invention includes a gas flow channel, a liquid flow channel, an ozone generation unit, a gas-liquid mixing unit, a gas-liquid separation unit, a housing, an ozone detection unit, and a control unit. It has. The gas flow channel circulates gaseous ozone. The liquid channel circulates water in which ozone is dissolved.
　オゾン発生部は、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に供給する。気液混合部は、液体流路の一部を形成する。気液混合部には、気体流路の一端が接続されている。気液混合部は、オゾン発生部から気体流路に供給されるオゾンを、液体流路を流通する水に気体流路の一端から溶解させる。気液分離部は、液体流路のうちの気液混合部よりも水の流れ方向の下流の一部を形成する。気液分離部には、気体流路の他端が接続されている。気液分離部は、液体流路を流通する水からオゾンの気泡を分離させ且つオゾンの一部を気体流路の他端から気体流路に排気する。 The ozone generation unit generates gaseous ozone and supplies the generated ozone to the gas flow path. The gas-liquid mixing unit forms part of the liquid flow path. One end of a gas flow path is connected to the gas-liquid mixing unit. The gas-liquid mixing unit dissolves ozone supplied from the ozone generation unit to the gas channel in water flowing through the liquid channel from one end of the gas channel. The gas-liquid separation unit forms a part of the liquid flow path downstream of the gas-liquid mixing unit in the water flow direction. The other end of the gas flow path is connected to the gas-liquid separator. The gas-liquid separation unit separates the bubbles of ozone from the water flowing through the liquid channel and exhausts a part of the ozone from the other end of the gas channel to the gas channel.
　筐体は、気体流路と、液体流路と、オゾン発生部と、気液混合部と、気液分離部とを収容する。オゾン検知部は、筐体に設けられ、オゾンを検知する。制御部は、オゾン検知部によってオゾンが検知される場合に、オゾンの生成を停止させるようにオゾン発生部を制御する。 The housing accommodates a gas channel, a liquid channel, an ozone generation unit, a gas-liquid mixing unit, and a gas-liquid separation unit. The ozone detector is provided in the housing and detects ozone. The control unit controls the ozone generation unit to stop the generation of ozone when ozone is detected by the ozone detection unit.
　本発明によれば、気体流路と液体流路とオゾン発生部と気液混合部と気液分離部とが筐体に収容されている。そのため、筐体の内部において気体状態のオゾンが漏出する場合でも、筐体の外部へのオゾンの放出を防止することができる。 According to the present invention, the gas flow path, the liquid flow path, the ozone generation part, the gas-liquid mixing part, and the gas-liquid separation part are accommodated in the casing. Therefore, even when gaseous ozone leaks inside the housing, it is possible to prevent the release of ozone to the outside of the housing.
　さらに、筐体の内部において気体状態のオゾンが漏出している場合には、筐体に設けられたオゾン検知部により、オゾンを検知することができる。オゾン検知部によってオゾンが検知される場合には、制御部がオゾン発生部を制御することにより、オゾン発生部はオゾンの生成を停止する。これにより、筐体の内部にオゾンがさらに漏出することを防止することができる。 Furthermore, when gaseous ozone leaks inside the casing, ozone can be detected by an ozone detector provided in the casing. When ozone is detected by the ozone detection unit, the control unit controls the ozone generation unit so that the ozone generation unit stops generating ozone. Thereby, it is possible to prevent further ozone from leaking into the housing.
　したがって、本発明によれば、オゾンガスの漏出によって環境に悪影響が及ぼされることを防止することが可能なオゾン水生成装置を提供することができる。 Therefore, according to the present invention, it is possible to provide an ozone water generating apparatus capable of preventing adverse effects on the environment due to leakage of ozone gas.
　本発明に従ったオゾン水生成装置において、好ましくは、オゾン検知部は、筐体の内部に配置されている。オゾン検知部は、好ましくは、筐体の内部のオゾンの濃度を検知する。制御部は、好ましくは、筐体の内部のオゾンの濃度が所定の濃度以上である場合に、オゾンの生成を停止させるようにオゾン発生部を制御する。 In the ozone water generating apparatus according to the present invention, preferably, the ozone detector is disposed inside the housing. The ozone detector preferably detects the concentration of ozone inside the housing. The control unit preferably controls the ozone generation unit to stop the generation of ozone when the concentration of ozone inside the housing is equal to or higher than a predetermined concentration.
　この構成によれば、筐体の内部において気体状態のオゾンが漏出している場合には、筐体の内部に配置されたオゾン検知部によってオゾンの濃度を検知することができる。筐体の内部のオゾンの濃度が所定の濃度以上である場合に、制御部がオゾン発生部を制御することにより、オゾン発生部はオゾンの生成を停止する。これにより、筐体の内部にオゾンがさらに漏出することを防止することができる。 According to this configuration, when gaseous ozone leaks inside the casing, the ozone concentration can be detected by the ozone detector disposed inside the casing. When the concentration of ozone inside the housing is equal to or higher than a predetermined concentration, the ozone generating unit stops generating ozone by the control unit controlling the ozone generating unit. Thereby, it is possible to prevent further ozone from leaking into the housing.
　本発明に従ったオゾン水生成装置において、好ましくは、オゾン検知部は、気液分離部に配置されている。オゾン検知部は、好ましくは、気液分離部の内部の水位を検知する。制御部は、好ましくは、気液分離部の内部の水位が所定の水位以上である場合に、オゾンの生成を停止させるようにオゾン発生部を制御する。 In the ozone water generating apparatus according to the present invention, preferably, the ozone detector is disposed in the gas-liquid separator. The ozone detection unit preferably detects the water level inside the gas-liquid separation unit. Preferably, the control unit controls the ozone generation unit to stop the generation of ozone when the water level inside the gas-liquid separation unit is equal to or higher than a predetermined water level.
　本発明に従ったオゾン水生成装置の気液分離部と気液混合部との間において気体状態のオゾンが気体流路から漏出している場合には、気液分離部の内部の気体の容積が減少することにより、オゾン水の水位が上昇する。本発明に従ったオゾン水生成装置においては、オゾン検知部は、気液分離部の内部の水位を検知する。また、制御部は、気液分離部の内部の水位が所定の水位以上である場合に、オゾンの生成を停止させるようにオゾン発生部を制御する。このように、本発明に従ったオゾン水生成装置の構成によれば、気液分離部の内部の水位に基づいて、筐体の内部にオゾンがさらに漏出することを防止することができる。 When ozone in a gas state leaks from the gas flow path between the gas-liquid separation unit and the gas-liquid mixing unit of the ozone water generating device according to the present invention, the volume of gas inside the gas-liquid separation unit As the water level decreases, the water level of ozone water rises. In the ozone water generating apparatus according to the present invention, the ozone detection unit detects the water level inside the gas-liquid separation unit. Moreover, a control part controls an ozone generation part so that the production | generation of ozone may be stopped when the water level inside a gas-liquid separation part is more than a predetermined water level. Thus, according to the configuration of the ozone water generating device according to the present invention, it is possible to prevent ozone from further leaking into the housing based on the water level inside the gas-liquid separator.
　本発明に従ったオゾン水生成装置において、好ましくは、気体流路の他端から気体流路にオゾンの一部を排気するための流出口が気液分離部に形成されている。気液分離部は、好ましくは、水位調整部を有している。水位調整部は、好ましくは、気液分離部の内部の水位が所定の水位以上である場合に、流出口を閉塞する。 In the ozone water generating apparatus according to the present invention, preferably, an outlet for exhausting a part of ozone from the other end of the gas channel to the gas channel is formed in the gas-liquid separation unit. The gas-liquid separation unit preferably has a water level adjustment unit. The water level adjusting unit preferably closes the outlet when the water level inside the gas-liquid separation unit is equal to or higher than a predetermined water level.
　この構成によれば、気液分離部と気液混合部との間において気体状態のオゾンが気体流路から漏出している場合でも、水位調整部が流出口を閉塞することにより、気液分離部から気体流路へのオゾンの流出を停止することができる。これにより、筐体の内部にオゾンがさらに漏出することを防止することができる。 According to this configuration, even when ozone in a gaseous state leaks from the gas flow path between the gas-liquid separation unit and the gas-liquid mixing unit, the water level adjustment unit blocks the outflow port, so that the gas-liquid separation is performed. The outflow of ozone from the section to the gas flow path can be stopped. Thereby, it is possible to prevent further ozone from leaking into the housing.
　また、水位調整部が流出口を閉塞することにより、気液分離部の内部に勢いよく溶液が流入する場合でも、流出口から溶液が噴出することを防止することができる。 Also, since the water level adjusting unit closes the outlet, it is possible to prevent the solution from being ejected from the outlet even when the solution flows into the gas-liquid separation unit vigorously.

FIG. 1 shows an ozone water generator 100 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 a housing 101.
　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。気体流路１１４には、逆止弁１１５が配置されている。 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. A check valve 115 is disposed in the gas flow path 114.
　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に接続されている。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.
　筐体１０１は、気体流路１１４と、液体流路１２１と、オゾン発生器１２０と、エジェクタ１３０と、気液分離部１４０とを収容する。筐体１０１には、開口部１２と開口部１３と開口部１４とが形成されている。気体導入部１１０の管路１１１を形成する管状部材は、開口部１４を通り且つ筐体１０１を貫通している。同様に、給水部１５０とエジェクタ１３０とを繋ぐ液体流路１２１の一部を形成する管状部材は、開口部１２を通り且つ筐体１０１を貫通している。気液分離部１４０と吐水部１６０とを繋ぐ液体流路１２１の一部を形成する管状部材は、開口部１３を通り且つ筐体１０１を貫通している。 The housing 101 accommodates a gas flow path 114, a liquid flow path 121, an ozone generator 120, an ejector 130, and a gas-liquid separation unit 140. An opening 12, an opening 13, and an opening 14 are formed in the housing 101. The tubular member that forms the pipe 111 of the gas introduction part 110 passes through the opening 14 and penetrates the housing 101. Similarly, a tubular member that forms a part of the liquid flow path 121 that connects the water supply unit 150 and the ejector 130 passes through the opening 12 and penetrates the housing 101. A tubular member that forms part of the liquid flow path 121 that connects the gas-liquid separator 140 and the water discharger 160 passes through the opening 13 and penetrates the housing 101.
　管路１１１を形成する管状部材の外周面（図示せず）と、開口部１４の縁（図示せず）との間の隙間は埋められている。同様に、給水部１５０とエジェクタ１３０とを繋ぐ液体流路１２１の一部を形成する管状部材の外周面（図示せず）と、開口部１２の縁（図示せず）との間の隙間は埋められている。気液分離部１４０と吐水部１６０とを繋ぐ液体流路１２１の一部を形成する管状部材の外周面（図示せず）と、開口部１３の縁（図示せず）との間の隙間は埋められている。このようにして、筐体１０１の内部は、密閉された空間が形成されている。 The clearance gap between the outer peripheral surface (not shown) of the tubular member which forms the pipe line 111, and the edge (not shown) of the opening part 14 is filled up. Similarly, the gap between the outer peripheral surface (not shown) of the tubular member that forms a part of the liquid flow path 121 that connects the water supply unit 150 and the ejector 130 and the edge (not shown) of the opening 12 is as follows. Buried. The gap between the outer peripheral surface (not shown) of the tubular member that forms a part of the liquid flow path 121 that connects the gas-liquid separator 140 and the water discharger 160 and the edge (not shown) of the opening 13 is Buried. In this way, a sealed space is formed inside the housing 101.
　オゾン水生成装置１００は、制御部１８０を備えている。制御部１８０は、筐体１０１の内部に配置されていてもよく、筐体１０１の外部に配置されていてもよい。 The ozone water generating apparatus 100 includes a control unit 180. The control unit 180 may be disposed inside the housing 101 or may be disposed outside the housing 101.
　筐体１０１の内部には、オゾンを検知するオゾン検知部１０８が配置されている。オゾン検知部１０８は、筐体１０１の内部のオゾンの濃度を検知する。濃度センサとしてのオゾン検知部１０８は、電気的または電子的に制御部１８０に接続されている。 Inside the housing 101, an ozone detector 108 that detects ozone is disposed. The ozone detection unit 108 detects the concentration of ozone inside the housing 101. The ozone detection unit 108 as a concentration sensor is electrically or electronically connected to the control unit 180.
　図２に示すように、制御部１８０は、データ読み取り部１８１と、判断部１８２とオゾン発生制御部１８３とを有している。データ読み取り部１８１は、オゾン検知部１０８から送信される信号を受け取る。オゾン検知部１０８から送信される信号には、筐体１０１の内部のオゾンの濃度の情報が含まれている。判断部１８２は、データ読み取り部１８１が受け取った信号に基づき、筐体１０１の内部のオゾンの濃度が所定の濃度以上であるかどうかを判定する。 As shown in FIG. 2, the control unit 180 includes a data reading unit 181, a determination unit 182, and an ozone generation control unit 183. The data reading unit 181 receives a signal transmitted from the ozone detection unit 108. The signal transmitted from the ozone detector 108 includes information on the concentration of ozone inside the housing 101. Based on the signal received by the data reading unit 181, the determination unit 182 determines whether the ozone concentration inside the housing 101 is equal to or higher than a predetermined concentration.
　オゾン発生制御部１８３は、オゾン発生器１２０を制御する。オゾン発生制御部１８３は、例えば図示しない電源回路を制御することにより、オゾン発生器１２０の電極に印加される電圧を調整する。判断部１８２によって、筐体１０１（図１参照）の内部のオゾンの濃度が所定の濃度以上であることが判定される場合には、オゾン発生制御部１８３は、オゾンの生成を停止させるようにオゾン発生器１２０の電極に印加される電圧を調整することにより、オゾン発生器１２０を制御する。なお、２点鎖線の矢印は信号の流れを示す。 The ozone generation control unit 183 controls the ozone generator 120. The ozone generation control unit 183 adjusts the voltage applied to the electrode of the ozone generator 120, for example, by controlling a power supply circuit (not shown). When the determination unit 182 determines that the ozone concentration in the housing 101 (see FIG. 1) is equal to or higher than the predetermined concentration, the ozone generation control unit 183 stops the generation of ozone. The ozone generator 120 is controlled by adjusting the voltage applied to the electrode of the ozone generator 120. The two-dot chain arrows indicate the signal flow.
　このようにして、制御部１８０は、オゾン検知部１０８によってオゾンが検知される場合に、オゾンの生成を停止させるようにオゾン発生器１２０を制御する。詳細には、制御部１８０は、筐体１０１の内部のオゾンの濃度が所定の濃度以上である場合に、オゾンの生成を停止させるようにオゾン発生器１２０を制御する。 Thus, the control unit 180 controls the ozone generator 120 so as to stop the generation of ozone when ozone is detected by the ozone detection unit 108. Specifically, the control unit 180 controls the ozone generator 120 to stop the generation of ozone when the concentration of ozone inside the housing 101 is equal to or higher than a predetermined concentration.

　栓部６１は、流出口１４３を塞ぐ栓としての機能を有している。栓部６１は、略円錐形状を有している。栓部６１は、フロートガイド６３の上面に固定されている。なお、栓部６１の形状は、特に限定されない。 The plug part 61 has a function as a plug that closes the outlet 143. The plug part 61 has a substantially conical shape. The plug part 61 is fixed to the upper surface of the float guide 63. The shape of the plug portion 61 is not particularly limited.
　フロート６２は、容器１０４に貯留される溶液の比重よりも小さい比重を有する物質からなる物体、または、所定の比重を有する中空の物体等によって形成されている。フロート６２は、容器１０４内部の溶液の液位に応じて上下に移動する。容器１０４へ貯留される溶液が増加することによって液位が所定の液位よりも高くなったときに、流出口１４３が弁６０によって塞がれる。容器１０４内部の液位が所定の液位よりも低いときには、流出口１４３は開放されている。このように、弁６０は、容器１０４の内部に溜められた液量に応じて流出口１４３を開閉する。 The float 62 is formed of an object made of a substance having a specific gravity smaller than the specific gravity of the solution stored in the container 104, a hollow object having a predetermined specific gravity, or the like. The float 62 moves up and down according to the liquid level of the solution inside the container 104. When the liquid level becomes higher than a predetermined liquid level due to an increase in the solution stored in the container 104, the outlet 143 is blocked by the valve 60. When the liquid level inside the container 104 is lower than a predetermined liquid level, the outflow port 143 is opened. As described above, the valve 60 opens and closes the outlet 143 according to the amount of liquid stored in the container 104.
　弁６０の構成によれば、フロートガイド６３の回転中心から栓部６１までの距離が、フロートガイド６３の回転中心からフロートガイド６３とフロート６２との接続部分までの距離よりも小さい。そのため、てこの原理によって、流出口１４３をより強固に閉塞することできる。さらに、比較的小さい浮力によってフロート６２が上下に移動する場合でも、栓部６１は流出口１４３を強固に閉塞することが可能であるため、弁６０の小型化が可能である。そのため、容器１０４内部の容積を大きく保ったまま、弁６０を配置させることができる。 According to the configuration of the valve 60, the distance from the rotation center of the float guide 63 to the plug portion 61 is smaller than the distance from the rotation center of the float guide 63 to the connecting portion between the float guide 63 and the float 62. Therefore, the outlet 143 can be closed more firmly by the lever principle. Further, even when the float 62 moves up and down by a relatively small buoyancy, the plug portion 61 can firmly block the outflow port 143, so that the valve 60 can be downsized. Therefore, the valve 60 can be arranged while keeping the volume inside the container 104 large.
　次に、図１と図３とを用いて、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. 1 and 3. 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３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、底面１４５から上方に向かって容器１０４の内部を流通するとともに、流入口１４１から流出口１４２に向かって容器１０４の幅方向に移動する。底面１４５と天井面１４６と周壁１４９の内面１４９ｓとに囲まれた空間に貯められた溶液は、流出口１４２の近傍において次第に加速されながら、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. 3, the water containing ozone that has flowed into the container 104 from the inside of the nozzle 21p circulates in the container 104 upward from the bottom surface 145, and from the inlet 141 toward the outlet 142. Then, the container 104 moves in the width direction. The solution stored in the space surrounded by the bottom surface 145, the ceiling surface 146, and the inner surface 149 s of the peripheral wall 149 flows out of the container 104 from the outlet 142 while being gradually accelerated in the vicinity of 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、オゾン水の水面の上方に集められる。水面の上方に集められた気体は、弁６０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, a gas such as ozone or air separated from the solution is collected above the surface of the ozone water while circulating inside the container 104. When the valve 60 opens the outlet 143, the gas collected above the water surface is discharged outside the gas-liquid separator 140 by flowing through the inside of the tubular portion 144 from the outlet 143. The
　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（図１参照）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). The ozone and air that are not dissolved in water flow into the ejector 130 (see FIG. 1) again 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.
　例えば気液分離部１４０とエジェクタ１３０との間に延びる気体流路１１４（図１参照）の一部からオゾンが漏出している場合、または、液体流路１２１を流通する水の量が一時的に増加する場合等には、容器１０４の内部に貯められた溶液の量が増加して水位が上昇する。容器１０４の内部の水位が所定の水位以上である場合には、弁６０によって流出口１４３が閉塞される。 For example, when ozone leaks from a part of the gas channel 114 (see FIG. 1) extending between the gas-liquid separator 140 and the ejector 130, or the amount of water flowing through the liquid channel 121 is temporarily For example, the amount of the solution stored in the container 104 increases and the water level rises. When the water level inside the container 104 is equal to or higher than a predetermined water level, the outlet 143 is closed by the valve 60.
　流出口１４３が閉塞されている場合には、気液分離部１４０からオゾン発生器１２０（図１参照）にオゾンが供給されないため、オゾン発生器１２０には気体導入部１１０（図１参照）から必要な気体が導入される。この場合には、オゾン発生器１２０が気体導入部１１０から気体を取り入れるように、制御部１８０（図２参照）がオゾン発生器１２０を制御する。このように、流出口１４３が弁６０によって閉塞されている場合に、オゾン発生器１２０は、気体導入部１１０から気体を導入することによって、オゾンを生成することができる。 When the outlet 143 is closed, ozone is not supplied from the gas-liquid separation unit 140 to the ozone generator 120 (see FIG. 1), and therefore, the ozone generator 120 is supplied from the gas introduction unit 110 (see FIG. 1). Necessary gas is introduced. In this case, the control unit 180 (see FIG. 2) controls the ozone generator 120 so that the ozone generator 120 takes in gas from the gas introduction unit 110. Thus, when the outlet 143 is closed by the valve 60, the ozone generator 120 can generate ozone by introducing gas from the gas introduction unit 110.
　以上のように、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、エジェクタ１３０と、気液分離部１４０と、筐体１０１と、オゾン検知部１０８と、制御部１８０とを備えている。気体流路１１４は、気体状態のオゾンを流通させる。液体流路１２１は、オゾンが溶解される水を流通させる。 As described above, the ozone water generating apparatus 100 includes the gas channel 114, the liquid channel 121, the ozone generator 120, the ejector 130, the gas-liquid separator 140, the housing 101, and the ozone detector 108. And a control unit 180. The gas flow path 114 circulates gaseous ozone. The liquid channel 121 circulates water in which ozone is dissolved.
　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。エジェクタ１３０は、液体流路１２１の一部を形成する。エジェクタ１３０には、気体流路１１４の一端が接続されている。エジェクタ１３０は、オゾン発生器１２０から気体流路１１４に供給されるオゾンを、液体流路１２１を流通する水に気体流路１１４の一端から溶解させる。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する。気液分離部１４０には、気体流路１１４の他端が接続されている。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分離させ且つオゾンの一部を気体流路１１４の他端から気体流路１１４に排気する。 The ozone generator 120 generates gaseous ozone and supplies the generated ozone to the gas flow path 114. The ejector 130 forms part of the liquid channel 121. One end of a gas flow path 114 is connected to the ejector 130. The ejector 130 dissolves ozone supplied from the ozone generator 120 to the gas channel 114 in water flowing through the liquid channel 121 from one end of the gas channel 114. The gas-liquid separator 140 forms a part of the liquid flow path 121 downstream of the ejector 130 in the water flow direction. The other end of the gas flow path 114 is connected to the gas-liquid separation unit 140. The gas-liquid separation unit 140 separates ozone bubbles from the water flowing through the liquid channel 121 and exhausts part of the ozone from the other end of the gas channel 114 to the gas channel 114.
　筐体１０１は、気体流路１１４と、液体流路１２１と、オゾン発生器１２０と、エジェクタ１３０と、気液分離部１４０とを収容する。オゾン検知部１０８は、筐体１０１に設けられ、オゾンを検知する。制御部１８０は、オゾン検知部１０８によってオゾンが検知される場合に、オゾンの生成を停止させるようにオゾン発生器１２０を制御する。 The housing 101 accommodates a gas flow path 114, a liquid flow path 121, an ozone generator 120, an ejector 130, and a gas-liquid separation unit 140. The ozone detection unit 108 is provided in the housing 101 and detects ozone. The control unit 180 controls the ozone generator 120 so as to stop the generation of ozone when ozone is detected by the ozone detection unit 108.
　オゾン水生成装置１００によれば、気体流路１１４と液体流路１２１とオゾン発生器１２０とエジェクタ１３０と気液分離部１４０とが筐体１０１に収容されている。そのため、筐体１０１の内部において気体状態のオゾンが漏出する場合でも、筐体１０１の外部へのオゾンの放出を防止することができる。 According to the ozone water generating apparatus 100, the gas flow path 114, the liquid flow path 121, the ozone generator 120, the ejector 130, and the gas-liquid separation unit 140 are accommodated in the housing 101. Therefore, even when gaseous ozone leaks inside the housing 101, the release of ozone to the outside of the housing 101 can be prevented.
　さらに、筐体１０１の内部において気体状態のオゾンが漏出している場合には、筐体１０１に設けられたオゾン検知部１０８により、オゾンを検知することができる。オゾン検知部１０８によってオゾンが検知される場合には、制御部１８０がオゾン発生器１２０を制御することにより、オゾン発生器１２０はオゾンの生成を停止する。これにより、筐体１０１の内部にオゾンがさらに漏出することを防止することができる。 Furthermore, when gaseous ozone leaks inside the casing 101, the ozone can be detected by the ozone detector 108 provided in the casing 101. When ozone is detected by the ozone detector 108, the controller 180 controls the ozone generator 120, so that the ozone generator 120 stops generating ozone. Thereby, it is possible to prevent further ozone from leaking into the housing 101.
　このようにして、オゾンガスの漏出によって環境に悪影響が及ぼされることを防止することが可能なオゾン水生成装置１００を提供することができる。 In this way, it is possible to provide the ozone water generation apparatus 100 that can prevent the environment from being adversely affected by leakage of ozone gas.
　オゾン水生成装置１００において、オゾン検知部１０８は、筐体１０１の内部に配置されている。オゾン検知部１０８は、筐体１０１の内部のオゾンの濃度を検知する。制御部１８０は、筐体１０１の内部のオゾンの濃度が所定の濃度以上である場合に、オゾンの生成を停止させるようにオゾン発生器１２０を制御する。 In the ozone water generating apparatus 100, the ozone detector 108 is disposed inside the housing 101. The ozone detection unit 108 detects the concentration of ozone inside the housing 101. The control unit 180 controls the ozone generator 120 to stop the generation of ozone when the concentration of ozone inside the housing 101 is equal to or higher than a predetermined concentration.
　この構成によれば、筐体１０１の内部において気体状態のオゾンが漏出している場合には、筐体１０１の内部に配置されたオゾン検知部１０８によってオゾンの濃度を検知することができる。筐体１０１の内部のオゾンの濃度が所定の濃度以上である場合に、制御部１８０がオゾン発生器１２０を制御することにより、オゾン発生器１２０はオゾンの生成を停止する。これにより、筐体１０１の内部にオゾンがさらに漏出することを防止することができる。 According to this configuration, when gaseous ozone leaks inside the casing 101, the ozone concentration can be detected by the ozone detector 108 disposed inside the casing 101. When the concentration of ozone inside the housing 101 is equal to or higher than a predetermined concentration, the controller 180 controls the ozone generator 120 so that the ozone generator 120 stops generating ozone. Thereby, it is possible to prevent further ozone from leaking into the housing 101.
　オゾン水生成装置１００において、気液分離部１４０の容器１０４に流出口１４３が形成されている。流出口１４３は、気体流路１１４の他端から気体流路１１４にオゾンの一部を排気させる。気液分離部１４０は、弁６０を有している。弁６０は、気液分離部１４０の内部の水位が所定の水位以上である場合に、流出口１４３を閉塞する。 In the ozone water generating apparatus 100, an outlet 143 is formed in the container 104 of the gas-liquid separator 140. The outflow port 143 exhausts a part of ozone from the other end of the gas channel 114 to the gas channel 114. The gas-liquid separator 140 has a valve 60. The valve 60 closes the outflow port 143 when the water level inside the gas-liquid separator 140 is equal to or higher than a predetermined water level.
　この構成によれば、気液分離部１４０とエジェクタ１３０との間において気体状態のオゾンが気体流路１１４から漏出している場合でも、弁６０が流出口１４３を閉塞することにより、気液分離部１４０から気体流路１１４へのオゾンの流出を停止することができる。これにより、筐体１０１の内部にオゾンがさらに漏出することを防止することができる。また、弁６０が流出口１４３を閉塞することにより、容器１０４の内部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 this configuration, even when gaseous ozone leaks from the gas flow path 114 between the gas-liquid separator 140 and the ejector 130, the valve 60 blocks the outlet 143, so that the gas-liquid separation is performed. The outflow of ozone from the portion 140 to the gas flow path 114 can be stopped. Thereby, it is possible to prevent further ozone from leaking into the housing 101. Further, since the valve 60 closes the outflow port 143, it is possible to prevent the solution from being ejected from the outflow port 143 even when the solution vigorously flows into the container 104.
　なお、筐体１０１の内部のオゾンの濃度を検知するオゾン検知部１０８は、筐体１０１の外部に配置されていてもよい。 Note that the ozone detector 108 that detects the concentration of ozone inside the housing 101 may be disposed outside the housing 101.
　なお、オゾン水生成装置１００において、気体流路１１４には、逆止弁１１５が配置されていなくてもよい。つまり、オゾン水生成装置１００は、逆止弁１１５を備えていなくてもよい。 In the ozone water generating apparatus 100, the check valve 115 may not be disposed in the gas flow path 114. That is, the ozone water generating apparatus 100 may not include the check valve 115.
　なお、ノズル２１ｐが延びる方向と、ノズル２２ｐが延びる方向とは、それぞれ異なっていてもよい。ノズル２１ｐが延びる方向と、ノズル２２ｐが延びる方向とは、略水平方向であることに限定されない。ただし、ノズル２１ｐは、ノズル２１ｐの内部から容器１０４の内部に略水平方向に溶液が流入するように、容器１０４に取り付けられていることが好ましい。また、ノズル２２ｐは、容器１０４の内部からノズル２２ｐの内部に略水平方向に溶液が流出するように、容器１０４に取り付けられていることが好ましい。 The direction in which the nozzle 21p extends may be different from the direction in which the nozzle 22p extends. 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.
　流出口１４３は、天井面１４６にではなく、流入口１４１が形成された周壁１４９と反対側の周壁１４９（図３の右側の周壁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 opposite to the peripheral wall 149 where the inlet 141 is formed (the peripheral wall 149 on the right side in FIG. 3).
　弁６０は、図３に示す構成を備えていることに限定されない。例えば容器１０４においての流出口１４３の位置に応じて、栓部６１が周壁１４９に対向するように、弁６０は構成されていてもよい。 The valve 60 is not limited to having the configuration shown in FIG. For example, the valve 60 may be configured such that the plug portion 61 faces 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、制御部１８０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. FIG. 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. This three-way valve is electronically controlled, for example, and is controlled by the control unit 180.
　接続部１１３の位置は、気体流路１１４のうち、オゾン発生器１２０とエジェクタ１３０との間であってもよい。つまり、管路１１１は、気体流路１１４のうち、オゾン発生器１２０とエジェクタ１３０との間を延びる部分に接続されていてもよい。 The position of the connecting portion 113 may be between the ozone generator 120 and the ejector 130 in the gas flow path 114. That is, the pipe line 111 may be connected to a portion of the gas flow path 114 that extends between the ozone generator 120 and the ejector 130.
　なお、気液混合部の構成は、エジェクタ型のものに限定されず、気体流路１１４から導入されたオゾンと液体流路１２１を流通する水とを混合させ、且つ、オゾンを水に溶解させる構成を有していればよい。 The configuration of the gas-liquid mixing unit is not limited to the ejector type, and the ozone introduced from the gas flow channel 114 and the water flowing through the liquid flow channel 121 are mixed and the ozone is dissolved in the water. What is necessary is just to have a structure.
　（第２実施形態）
　以下では、第２実施形態に係るオゾン水生成装置２００について、図４～図６を用いて説明する。なお、以下において、第１実施形態に係るオゾン水生成装置１００の構成と同様の機能を有する構成には同符号を付し、その説明を省略する。 (Second Embodiment)
Hereinafter, an ozone water generating apparatus 200 according to the second embodiment will be described with reference to FIGS. 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２００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、オゾン水生成装置２００は、気液分離部１４０の代わりに気液分離部２４０を備え、且つ、オゾン検知部１０８の代わりに水位検知部２０８を備えている。 As will be described below, the ozone water generating device 200 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 200 is replaced with a gas-liquid separator 140. A gas-liquid separation unit 240 is provided, and a water level detection unit 208 is provided instead of the ozone detection unit 108.
　図６に示すように、気液分離部２４０の上部には、水位検知部２０８が配置されている。水位検知部２０８は、容器１０４の内部の水位として、弁６０の栓部６１の位置を検知する。位置センサとしての水位検知部２０８は、電気的または電子的に制御部１８０（図５参照）に接続されている。水位検知部２０８は、オゾン検知部の一例である。 As shown in FIG. 6, a water level detection unit 208 is disposed above the gas-liquid separation unit 240. The water level detection unit 208 detects the position of the plug unit 61 of the valve 60 as the water level inside the container 104. The water level detection unit 208 as a position sensor is electrically or electronically connected to the control unit 180 (see FIG. 5). The water level detection unit 208 is an example of an ozone detection unit.
　データ読み取り部１８１は、水位検知部２０８から送信される信号を受け取る。水位検知部２０８から送信される信号には、容器１０４においての栓部６１の位置の情報が含まれている。判断部１８２は、データ読み取り部１８１が受け取った信号に基づき、栓部６１の位置が所定の位置よりも上方であるかどうか、または、栓部６１の位置が所定の位置に達したか否かを判定する。 The data reading unit 181 receives a signal transmitted from the water level detection unit 208. The signal transmitted from the water level detection unit 208 includes information on the position of the plug unit 61 in the container 104. Based on the signal received by the data reading unit 181, the determination unit 182 determines whether the position of the plug unit 61 is above a predetermined position, or whether the position of the plug unit 61 has reached a predetermined position. Determine.
　判断部１８２によって、栓部６１の位置が所定の位置よりも上方であることが判定される場合には、オゾン発生制御部１８３は、オゾンの生成を停止させるようにオゾン発生器１２０の電極に印加される電圧を調整することにより、オゾン発生器１２０を制御する。あるいは、判断部１８２によって、栓部６１の位置が所定の位置に達したことが判定される場合に、オゾン発生制御部１８３は、オゾンの生成を停止させるようにオゾン発生器１２０の電極に印加される電圧を調整することにより、オゾン発生器１２０を制御する。 When the determination unit 182 determines that the position of the plug unit 61 is above the predetermined position, the ozone generation control unit 183 applies the electrode of the ozone generator 120 so as to stop the generation of ozone. The ozone generator 120 is controlled by adjusting the applied voltage. Alternatively, when the determination unit 182 determines that the position of the plug unit 61 has reached a predetermined position, the ozone generation control unit 183 applies the voltage to the electrode of the ozone generator 120 so as to stop the generation of ozone. The ozone generator 120 is controlled by adjusting the applied voltage.
　例えば気液分離部２４０とエジェクタ１３０との間に延びる気体流路１１４（図４参照）の一部からオゾンが漏出している場合には、容器１０４の内部に貯められた溶液の量が増加して水位が上昇する。容器１０４の内部の水位が所定の水位以上である場合には、弁６０によって流出口１４３が閉塞される。そのため、容器１０４においての栓部６１の位置を水位検知部２０８が検知することにより、気体流路１１４の一部からオゾンが漏出しているか否かを判断部１８２が判定することができる。 For example, when ozone leaks from a part of the gas flow path 114 (see FIG. 4) extending between the gas-liquid separator 240 and the ejector 130, the amount of the solution stored in the container 104 increases. Then the water level rises. When the water level inside the container 104 is equal to or higher than a predetermined water level, the outlet 143 is closed by the valve 60. Therefore, when the water level detection unit 208 detects the position of the plug unit 61 in the container 104, the determination unit 182 can determine whether ozone has leaked from a part of the gas flow path 114.
　なお、水位検知部２０８は、栓部６１が流出口１４３を閉塞したか否かを検知していてもよい。あるいは、水位検知部２０８は、栓部６１が流出口１４３を閉塞することにより、気液分離部２４０から気体流路１１４への気体の流通が停止されたか否かを検知していてもよい。 The water level detection unit 208 may detect whether or not the plug unit 61 has blocked the outlet 143. Alternatively, the water level detection unit 208 may detect whether or not the gas flow from the gas-liquid separation unit 240 to the gas flow path 114 is stopped by the plug unit 61 closing the outlet 143.
　このようにして、制御部１８０は、容器１０４の内部の水位が所定の水位以上である場合に、オゾンの生成を停止させるようにオゾン発生器１２０を制御する。つまり、制御部１８０は、水位検知部２０８によって検知される容器１０４においての栓部６１の位置に基づいてオゾンが検知される場合に、オゾンの生成を停止させるようにオゾン発生器１２０を制御する。 Thus, the control unit 180 controls the ozone generator 120 so as to stop the generation of ozone when the water level inside the container 104 is equal to or higher than the predetermined water level. That is, the control unit 180 controls the ozone generator 120 to stop the generation of ozone when ozone is detected based on the position of the stopper 61 in the container 104 detected by the water level detection unit 208. .
　以上のように、オゾン水生成装置２００において、オゾン検知部としての水位検知部２０８は、気液分離部２４０に配置されている。水位検知部２０８は、気液分離部２４０の容器１０４の内部の水位を検知する。制御部１８０は、容器１０４の内部の水位が所定の水位以上である場合に、オゾンの生成を停止させるようにオゾン発生器１２０を制御する。 As described above, in the ozone water generating apparatus 200, the water level detection unit 208 as the ozone detection unit is disposed in the gas-liquid separation unit 240. The water level detection unit 208 detects the water level inside the container 104 of the gas-liquid separation unit 240. The control unit 180 controls the ozone generator 120 to stop the generation of ozone when the water level inside the container 104 is equal to or higher than a predetermined water level.
　オゾン水生成装置２００の気液分離部２４０とエジェクタ１３０との間において気体状態のオゾンが気体流路１１４から漏出している場合には、気液分離部２４０の容器１０４の内部の気体の容積が減少することにより、オゾン水の水位が上昇する。オゾン水生成装置２００においては、水位検知部２０８は、気液分離部２４０の容器１０４の内部の水位を検知する。また、制御部１８０は、容器１０４の内部の水位が所定の水位以上である場合に、オゾンの生成を停止させるようにオゾン発生器１２０を制御する。このように、オゾン水生成装置２００によれば、気液分離部２４０の内部の水位に基づいて、筐体１０１の内部にオゾンがさらに漏出することを防止することができる。 When ozone in a gaseous state leaks from the gas flow path 114 between the gas-liquid separator 240 and the ejector 130 of the ozone water generator 200, the volume of gas inside the container 104 of the gas-liquid separator 240. As the water level decreases, the water level of ozone water rises. In the ozone water generating apparatus 200, the water level detection unit 208 detects the water level inside the container 104 of the gas-liquid separation unit 240. Moreover, the control part 180 controls the ozone generator 120 so that the production | generation of ozone is stopped when the water level inside the container 104 is more than a predetermined water level. Thus, according to the ozone water generating apparatus 200, it is possible to prevent further ozone from leaking into the housing 101 based on the water level inside the gas-liquid separator 240.

The ozone generator 120 is controlled by adjusting the applied voltage.
