ETFE), polytetrafluoroethylene (PTFE), etc.).
　以下、飲料供給システム１の各構成要素について詳細に説明する。 Hereinafter, each component of the beverage supply system 1 will be described in detail.
　ガス供給源１０は、炭酸ガス（二酸化炭素ガス）、窒素ガス、圧縮空気等のガスを供給する。ガス供給源１０はガス減圧弁１１を含み、ガス供給源１０から供給されるガスの圧力はガス減圧弁１１によって調整される。ガス供給源１０は例えばガスボンベとして構成される。ガス供給源１０はガス供給路６０に接続され、ガス供給源１０から供給されたガスはガス供給路６０を通して飲料収容容器２０に供給される。 The gas supply source 10 supplies gas such as carbon dioxide gas (carbon dioxide gas), nitrogen gas, and compressed air. The gas supply source 10 includes a gas pressure reducing valve 11, and the pressure of the gas supplied from the gas supply source 10 is adjusted by the gas pressure reducing valve 11. The gas supply source 10 is configured as, for example, a gas cylinder. The gas supply source 10 is connected to the gas supply path 60, and the gas supplied from the gas supply source 10 is supplied to the beverage container 20 through the gas supply path 60.
　飲料収容容器２０は飲料を収容する。例えば、飲料収容容器２０は発泡性飲料を収容する。発泡性飲料には、ビール、ビールテイスト飲料、酎ハイ、ウィスキー含有飲料（ウィスキー、ハイボール等）、炭酸ジュース等が含まれる。ビールテイスト飲料には、発泡酒、麦芽以外の原料から生成され又は発泡酒に麦由来のアルコール飲料が混ぜられたビール風味の発泡アルコール飲料（いわゆる第三のビール）、ノンアルコールビール等が含まれる。飲料収容容器２０は、例えば、発泡性飲料を収容する飲料樽として構成される。 Beverage storage container 20 stores beverages. For example, the beverage storage container 20 stores a sparkling beverage. Effervescent beverages include beer, beer-taste beverages, chuhai, whiskey-containing beverages (whiskey, highball, etc.), carbonated juice, and the like. Beer-taste beverages include low-malt beer, beer-flavored low-malt beer (so-called third beer) produced from raw materials other than malt, or a mixture of low-malt alcohol and wheat-derived alcoholic beverage, non-alcoholic beer, and the like. .. The beverage storage container 20 is configured as, for example, a beverage barrel for accommodating a sparkling beverage.
　飲料収容容器２０は、飲料収容容器２０の口金として機能する公知のスピアバルブ（図示せず）を含む。スピアバルブは飲料収容容器２０の頂部から飲料収容容器２０の底部付近まで延在する。 The beverage storage container 20 includes a known spear valve (not shown) that functions as a base for the beverage storage container 20. The spear valve extends from the top of the beverage container 20 to near the bottom of the beverage container 20.
　また、飲料供給システム１はディスペンスヘッド５０を更に備える。ディスペンスヘッド５０は、飲料収容容器２０、具体的には飲料収容容器２０のスピアバルブに取り付けられる。 In addition, the beverage supply system 1 further includes a dispense head 50. The dispense head 50 is attached to the beverage storage container 20, specifically, the spear valve of the beverage storage container 20.
　ディスペンスヘッド５０は流体流入口５１及び流体流出口５２を含む。ガス供給路６０は、流体流入口５１に接続され、ディスペンスヘッド５０及びスピアバルブを介して飲料収容容器２０の内部と流体連通する。したがって、ガス供給路６０はディスペンスヘッド５０を介して飲料収容容器２０に接続されている。また、飲料移送路７０は、流体流出口５２に接続され、ディスペンスヘッド５０及びスピアバルブを介して飲料収容容器２０の内部と流体連通する。したがって、飲料移送路７０はディスペンスヘッド５０を介して飲料収容容器２０に接続されている。飲料収容容器２０内にガスが供給されると、ガスによって飲料の液面が押し下げられ、飲料がスピアバルブ通って上昇して飲料収容容器２０から飲料移送路７０に押し出される。 The dispense head 50 includes a fluid inlet 51 and a fluid outlet 52. The gas supply path 60 is connected to the fluid inflow port 51 and communicates with the inside of the beverage container 20 via the dispense head 50 and the spear valve. Therefore, the gas supply path 60 is connected to the beverage container 20 via the dispense head 50. Further, the beverage transfer path 70 is connected to the fluid outlet 52 and communicates with the inside of the beverage storage container 20 via the dispense head 50 and the spear valve. Therefore, the beverage transfer path 70 is connected to the beverage storage container 20 via the dispense head 50. When the gas is supplied into the beverage storage container 20, the liquid level of the beverage is pushed down by the gas, and the beverage rises through the spear valve and is pushed out from the beverage storage container 20 to the beverage transfer path 70.
　飲料ディスペンサ３０は、ガス供給源１０から供給されたガスによって飲料収容容器２０から移送された飲料を外部（飲料ディスペンサ３０の外部）に供給する。図１には、カバーが取り外された状態の飲料ディスペンサ３０が示される。飲料ディスペンサ３０は、コイル状の飲料導入管３１と、コック３２と、冷却水槽３３と、冷却装置３４とを含む。コック３２はタップとも称される。 The beverage dispenser 30 supplies the beverage transferred from the beverage storage container 20 by the gas supplied from the gas supply source 10 to the outside (outside the beverage dispenser 30). FIG. 1 shows the beverage dispenser 30 with the cover removed. The beverage dispenser 30 includes a coiled beverage introduction pipe 31, a cock 32, a cooling water tank 33, and a cooling device 34. The cock 32 is also called a tap.
　飲料導入管３１の一方の端部は飲料移送路７０に接続され、飲料導入管３１の他方の端部はコック３２に接続される。飲料収容容器２０から移送された飲料は飲料導入管３１を通ってコック３２に到達する。このとき、ユーザによってコック３２のハンドル３２１が操作される（例えばハンドル３２１が手前に引かれる）と、コック３２から容器（ジョッキ、グラス等）に飲料が注がれる。容器は、ユーザによってコック３２の下方に予め設置される。 One end of the beverage introduction pipe 31 is connected to the beverage transfer path 70, and the other end of the beverage introduction pipe 31 is connected to the cock 32. The beverage transferred from the beverage storage container 20 reaches the cock 32 through the beverage introduction pipe 31. At this time, when the handle 321 of the cock 32 is operated by the user (for example, the handle 321 is pulled toward the front), the beverage is poured from the cock 32 into the container (mug, glass, etc.). The container is pre-installed by the user below the cock 32.
　ユーザは冷却水槽３３に水を予め供給し、冷却水槽３３は水で満たされる。冷却装置３４は、冷凍機（図示せず）と、コイル状の冷媒流通管３５と、攪拌機３６とを含む。冷却装置３４は、冷凍機から冷媒流通管３５に供給された冷媒によって冷媒流通管３５の周囲に氷を生成し、氷によって冷却水槽３３内の水を冷却する。攪拌機３６は、冷却水槽３３内の水の温度が均一になるように冷却水槽３３内の水を攪拌する。飲料ディスペンサ３０に移送された飲料は、飲料導入管３１を通過するとき、冷却水槽３３内の冷却水によって冷却される。このため、飲料供給システム１は、飲料収容容器２０内の飲料が常温であったとしても、所望の冷えた飲料を飲料ディスペンサ３０から外部に供給することができる。 The user supplies water to the cooling water tank 33 in advance, and the cooling water tank 33 is filled with water. The cooling device 34 includes a refrigerator (not shown), a coiled refrigerant flow pipe 35, and a stirrer 36. The cooling device 34 generates ice around the refrigerant flow pipe 35 by the refrigerant supplied from the refrigerator to the refrigerant flow pipe 35, and cools the water in the cooling water tank 33 by the ice. The stirrer 36 stirs the water in the cooling water tank 33 so that the temperature of the water in the cooling water tank 33 becomes uniform. The beverage transferred to the beverage dispenser 30 is cooled by the cooling water in the cooling water tank 33 when passing through the beverage introduction pipe 31. Therefore, the beverage supply system 1 can supply a desired cold beverage from the beverage dispenser 30 to the outside even if the beverage in the beverage storage container 20 is at room temperature.

　飲料供給システム１による飲料の供給が終了した後には、飲料の流路に飲料が残される。残された飲料は、飲料の劣化、微生物の繁殖等を引き起こす。このため、飲料の味の低下を防止するためには、飲料供給システム１を定期的に洗浄する必要がある。 <Beverage supply system cleaning device>
After the beverage supply by the beverage supply system 1 is completed, the beverage is left in the beverage flow path. The remaining beverage causes deterioration of the beverage, propagation of microorganisms, and the like. Therefore, in order to prevent the taste of the beverage from deteriorating, it is necessary to wash the beverage supply system 1 on a regular basis.
　本実施形態では、飲料供給システム１の洗浄装置（以下、単に「洗浄装置」と称する）が飲料供給システム１の洗浄を行う。具体的には、洗浄装置は、飲料供給システム１の飲料の流路、すなわち飲料移送路７０及び飲料ディスペンサ３０（飲料導入管３１及びコック３２）を洗浄する。 In the present embodiment, the cleaning device of the beverage supply system 1 (hereinafter, simply referred to as “cleaning device”) cleans the beverage supply system 1. Specifically, the cleaning device cleans the beverage flow path of the beverage supply system 1, that is, the beverage transfer path 70 and the beverage dispenser 30 (beverage introduction pipe 31 and cock 32).
　図２は、本発明の第一実施形態に係る洗浄装置の構成を概略的に示す図である。図２には、図１の制御ボックス４０の内部が示されている。飲料供給システム１の構成要素の一部は洗浄装置の構成要素としても機能する。 FIG. 2 is a diagram schematically showing the configuration of the cleaning device according to the first embodiment of the present invention. FIG. 2 shows the inside of the control box 40 of FIG. Some of the components of the beverage supply system 1 also function as components of the cleaning device.
　洗浄装置は、飲料移送路７０にガスを供給するガス供給路６０と、飲料移送路７０に水を供給する水供給路９０と、制御ボックス４０と、ディスペンスヘッド５０とを備える。ガス供給路６０の一部及び水供給路９０の一部は、制御ボックス４０内に配置され、制御ボックス４０によって外部から隠される。 The cleaning device includes a gas supply path 60 for supplying gas to the beverage transfer path 70, a water supply path 90 for supplying water to the beverage transfer path 70, a control box 40, and a dispense head 50. A part of the gas supply path 60 and a part of the water supply path 90 are arranged in the control box 40 and hidden from the outside by the control box 40.
　水供給路９０は、水を供給する水供給源１００に接続される。水供給路９０には水減圧弁１１０が設けられ、水供給源１００から供給される水の圧力は水減圧弁１１０によって調整される。水供給源１００は例えば水道栓として構成される。飲料移送路７０に供給される水は洗浄液として機能する。 The water supply path 90 is connected to the water supply source 100 that supplies water. The water pressure reducing valve 110 is provided in the water supply path 90, and the pressure of the water supplied from the water supply source 100 is adjusted by the water pressure reducing valve 110. The water supply source 100 is configured as, for example, a tap. The water supplied to the beverage transfer path 70 functions as a cleaning liquid.
　ガス供給路６０及び水供給路９０は、制御ボックス４０内で一つの共有流路に統合され、共有流路を介してディスペンスヘッド５０に接続される。ガス供給路６０は第１継手４１を介して制御ボックス４０に接続される。第１継手４１は制御ボックス４０のガス流入口として機能する。水供給路９０は第２継手４２を介して制御ボックス４０に接続される。第２継手４２は制御ボックス４０の水流入口として機能する。ガス供給路６０及び水供給路９０の共有流路は第３継手４３を介して制御ボックス４０に接続される。第３継手４３は制御ボックス４０の流体流出口として機能する。 The gas supply path 60 and the water supply path 90 are integrated into one common flow path in the control box 40 and connected to the dispense head 50 via the common flow path. The gas supply path 60 is connected to the control box 40 via the first joint 41. The first joint 41 functions as a gas inlet of the control box 40. The water supply path 90 is connected to the control box 40 via the second joint 42. The second joint 42 functions as a water inlet of the control box 40. The shared flow path of the gas supply path 60 and the water supply path 90 is connected to the control box 40 via the third joint 43. The third joint 43 functions as a fluid outlet of the control box 40.
　ディスペンスヘッド５０は、ガス供給路６０及び水供給路９０の共有流路に接続された流体流入口５１と、飲料移送路７０に接続された流体流出口５２との接続状態を切り替えるように構成されている。ディスペンスヘッド５０は、操作レバー５３（図１参照）を含み、ユーザによって操作レバー５３が操作されたときに流体流入口５１と流体流出口５２との接続状態を切り替える。例えば、操作レバー５３は、上下方向に移動可能であり、３つの位置（上方位置、中間位置及び下方位置）の間で切り替えられる。 The dispense head 50 is configured to switch the connection state between the fluid inlet 51 connected to the common flow path of the gas supply path 60 and the water supply path 90 and the fluid outlet 52 connected to the beverage transfer path 70. ing. The dispense head 50 includes an operating lever 53 (see FIG. 1), and switches the connection state between the fluid inlet 51 and the fluid outlet 52 when the operating lever 53 is operated by the user. For example, the operating lever 53 is movable in the vertical direction and can be switched between three positions (upper position, intermediate position and lower position).
　ディスペンスヘッド５０は、操作レバー５３が下方位置にあるときに、流体流入口５１と飲料収容容器２０の内部とを接続し、飲料収容容器２０の内部と流体流出口５２とを接続する。すなわち、ディスペンスヘッド５０は、操作レバー５３が下方位置にあるときに、ガス供給路６０及び水供給路９０の共有流路を飲料収容容器２０の内部を介して飲料移送路７０に接続する。 The dispense head 50 connects the fluid inlet 51 and the inside of the beverage container 20 and connects the inside of the beverage container 20 and the fluid outlet 52 when the operating lever 53 is in the lower position. That is, the dispense head 50 connects the common flow path of the gas supply path 60 and the water supply path 90 to the beverage transfer path 70 via the inside of the beverage storage container 20 when the operation lever 53 is in the lower position.
　ディスペンスヘッド５０は、操作レバー５３が中間位置にあるときに、流体流入口５１と流体流出口５２とを直接接続し、流体流入口５１及び流体流出口５２を飲料収容容器２０の内部から遮断する。すなわち、ディスペンスヘッド５０は、操作レバー５３が中間位置にあるときに、ガス供給路６０及び水供給路９０の共有流路を飲料移送路７０に直接接続する。 When the operating lever 53 is in the intermediate position, the dispense head 50 directly connects the fluid inlet 51 and the fluid outlet 52, and shuts off the fluid inlet 51 and the fluid outlet 52 from the inside of the beverage container 20. .. That is, the dispense head 50 directly connects the common flow path of the gas supply path 60 and the water supply path 90 to the beverage transfer path 70 when the operation lever 53 is in the intermediate position.
　ディスペンスヘッド５０は、操作レバー５３が上方位置にあるときに、流体流入口５１、飲料収容容器２０の内部及び流体流出口５２を互いから遮断する。すなわち、ディスペンスヘッド５０は、操作レバー５３が上方位置にあるときに、ガス供給路６０及び水供給路９０の共有流路を飲料収容容器２０の内部及び飲料移送路７０に接続しない。 The dispense head 50 shuts off the fluid inlet 51, the inside of the beverage storage container 20, and the fluid outlet 52 from each other when the operating lever 53 is in the upper position. That is, the dispense head 50 does not connect the common flow path of the gas supply path 60 and the water supply path 90 to the inside of the beverage storage container 20 and the beverage transfer path 70 when the operation lever 53 is in the upper position.
　洗浄装置は制御装置８０を更に備える。制御装置８０は、制御ボックス４０内に配置され、制御ボックス４０によって外部から隠される。 The cleaning device further includes a control device 80. The control device 80 is arranged in the control box 40 and is hidden from the outside by the control box 40.
　図３は、図２の制御装置８０の構成を概略的に示す図である。制御装置８０は、メモリ８１、周辺回路８２及びプロセッサ８３を含む。メモリ８１及び周辺回路８２は信号線を介してプロセッサ８３に接続されている。制御装置８０は例えばマイコン又はシーケンサーとして構成される。 FIG. 3 is a diagram schematically showing the configuration of the control device 80 of FIG. The control device 80 includes a memory 81, a peripheral circuit 82, and a processor 83. The memory 81 and the peripheral circuit 82 are connected to the processor 83 via a signal line. The control device 80 is configured as, for example, a microcomputer or a sequencer.
　メモリ８１は、例えば、揮発性の半導体メモリ（例えば、ＲＡＭ）及び不揮発性の半導体メモリ（例えば、ＲＯＭ）を有する。メモリ８１は、プロセッサ８３によって実行されるプログラム、プロセッサ８３によって各種処理が実行されるときに使用される各種データ等を記憶する。 The memory 81 has, for example, a volatile semiconductor memory (for example, RAM) and a non-volatile semiconductor memory (for example, ROM). The memory 81 stores a program executed by the processor 83, various data used when various processes are executed by the processor 83, and the like.
　周辺回路８２は、プロセッサ８３が各種処理を実行するために必要な追加の要素（例えばタイマ等）を含む。プロセッサ８３は、一つ又は複数のＣＰＵ(Central Processing Unit)を有し、各種処理を実行する。 The peripheral circuit 82 includes additional elements (for example, a timer, etc.) necessary for the processor 83 to execute various processes. The processor 83 has one or a plurality of CPUs (Central Processing Units) and executes various processes.
　図２に示されるように、洗浄装置は、ガス開閉弁６１、ガス逆止弁６２、水開閉弁９１及び水逆止弁９２を更に備える。ガス開閉弁６１は、ガス供給路６０に配置され、ガス供給路６０を開閉する。ガス開閉弁６１は、例えば、ガス供給路６０内に配置された電磁弁である。なお、ガス開閉弁６１は、ガス供給路６０の周囲に配置されたピンチ弁であってもよい。ガス開閉弁６１は制御装置８０に電気的に接続され、制御装置８０はガス開閉弁６１を制御する。 As shown in FIG. 2, the cleaning device further includes a gas on-off valve 61, a gas check valve 62, a water on-off valve 91, and a water check valve 92. The gas on-off valve 61 is arranged in the gas supply path 60 and opens and closes the gas supply path 60. The gas on-off valve 61 is, for example, a solenoid valve arranged in the gas supply path 60. The gas on-off valve 61 may be a pinch valve arranged around the gas supply path 60. The gas on-off valve 61 is electrically connected to the control device 80, and the control device 80 controls the gas on-off valve 61.
　ガス逆止弁６２は、ガス供給路６０に配置され、ガスの逆流（ガス供給源１０への流れ）を防止する。本実施形態では、ガス逆止弁６２はガス開閉弁６１よりも下流側のガス供給路６０に配置される。 The gas check valve 62 is arranged in the gas supply path 60 to prevent backflow of gas (flow to the gas supply source 10). In the present embodiment, the gas check valve 62 is arranged in the gas supply path 60 on the downstream side of the gas on-off valve 61.
　水開閉弁９１は、水供給路９０に配置され、水供給路９０を開閉する。水開閉弁９１は、例えば、水供給路９０内に配置された電磁弁である。なお、水開閉弁９１は、水供給路９０の周囲に配置されたピンチ弁であってもよい。水開閉弁９１は制御装置８０に電気的に接続され、制御装置８０は水開閉弁９１を制御する。 The water on-off valve 91 is arranged in the water supply path 90 and opens and closes the water supply path 90. The water on-off valve 91 is, for example, a solenoid valve arranged in the water supply path 90. The water on-off valve 91 may be a pinch valve arranged around the water supply path 90. The water on-off valve 91 is electrically connected to the control device 80, and the control device 80 controls the water on-off valve 91.
　水逆止弁９２は、水供給路９０に配置され、水の逆流（水供給源１００への流れ）を防止する。本実施形態では、水逆止弁９２は水開閉弁９１よりも下流側の水供給路９０に配置される。 The water check valve 92 is arranged in the water supply path 90 to prevent backflow of water (flow to the water supply source 100). In the present embodiment, the water check valve 92 is arranged in the water supply path 90 on the downstream side of the water on-off valve 91.
　本実施形態では、ガス開閉弁６１は非通電時にガス供給路６０を開き且つ通電時にガス供給路６０を閉じるように構成される。一方、水開閉弁９１は非通電時に水供給路９０を閉じ且つ通電時に水供給路９０を開くように構成される。 In the present embodiment, the gas on-off valve 61 is configured to open the gas supply path 60 when not energized and close the gas supply path 60 when energized. On the other hand, the water on-off valve 91 is configured to close the water supply path 90 when the power is off and open the water supply path 90 when the power is on.
　ユーザは、飲料ディスペンサ３０から飲料を供給するとき、ディスペンスヘッド５０の操作レバー５３を下方位置に設定する。操作レバー５３が下方位置にあるときには、ガス供給路６０及び水供給路９０の共有流路が飲料収容容器２０の内部を介して飲料移送路７０に接続される。このとき、ガス開閉弁６１及び水開閉弁９１には電力が供給されていないため、ガス開閉弁６１はガス供給路６０を開き、水開閉弁９１は水供給路９０を閉じる。このため、ガス供給路６０から飲料収容容器２０にガスが供給され、飲料がガスによって飲料移送路７０を介して飲料ディスペンサ３０に移送される。 The user sets the operating lever 53 of the dispense head 50 to the lower position when the beverage is supplied from the beverage dispenser 30. When the operating lever 53 is in the lower position, the shared flow path of the gas supply path 60 and the water supply path 90 is connected to the beverage transfer path 70 via the inside of the beverage storage container 20. At this time, since power is not supplied to the gas on-off valve 61 and the water on-off valve 91, the gas on-off valve 61 opens the gas supply path 60, and the water on-off valve 91 closes the water supply path 90. Therefore, gas is supplied from the gas supply path 60 to the beverage container 20, and the beverage is transferred by the gas to the beverage dispenser 30 via the beverage transfer path 70.
　また、ユーザは、飲料収容容器２０を交換するとき、ディスペンスヘッド５０の交換レバーを上方位置に設定する。操作レバー５３が上方位置にあるときには、ガス供給路６０及び水供給路９０の共有流路が飲料収容容器２０の内部及び飲料移送路７０に接続されない。このため、飲料収容容器２０を交換するときのガス漏れを防止することができる。 Further, when replacing the beverage container 20, the user sets the replacement lever of the dispense head 50 to the upper position. When the operating lever 53 is in the upper position, the shared flow paths of the gas supply path 60 and the water supply path 90 are not connected to the inside of the beverage container 20 and the beverage transfer path 70. Therefore, it is possible to prevent gas leakage when the beverage container 20 is replaced.
　また、ユーザは、飲料供給システム１を洗浄するとき、ディスペンスヘッド５０の操作レバー５３を中間位置に設定し、飲料ディスペンサ３０のコック３２を開く。操作レバー５３が中間位置にあるときには、ガス供給路６０及び水供給路９０の共有流路が飲料移送路７０に直接接続される。このため、水供給源１００から供給された水によって飲料移送路７０及び飲料ディスペンサ３０を洗浄するときに、水が飲料収容容器２０の内部に流入することを防止することができる。飲料移送路７０及び飲料ディスペンサ３０を洗浄した水は、ユーザによって予め設置された回収容器２００（バケツ等）に回収される。 Further, when cleaning the beverage supply system 1, the user sets the operation lever 53 of the dispense head 50 to the intermediate position and opens the cock 32 of the beverage dispenser 30. When the operating lever 53 is in the intermediate position, the shared flow paths of the gas supply path 60 and the water supply path 90 are directly connected to the beverage transfer path 70. Therefore, when the beverage transfer path 70 and the beverage dispenser 30 are washed with the water supplied from the water supply source 100, it is possible to prevent the water from flowing into the beverage storage container 20. The water that has washed the beverage transfer path 70 and the beverage dispenser 30 is collected in a collection container 200 (bucket or the like) previously installed by the user.
　従来、飲料供給システム１の洗浄では、一度に多量の水を供給することによって洗浄力が高まると考えられていた。一方、本願の発明者は、鋭意検討の結果、水の線速を速めて水のエネルギーを高めることで、洗浄力が高まることを見出した。水の線速を速めるためには、一度に供給する水の量を少なくする必要がある。しかしながら、水の量が少ない場合には、飲料移送路７０内の抵抗によって飲料移送路７０内に水を流すことができない。 Conventionally, in the cleaning of the beverage supply system 1, it has been considered that the cleaning power is enhanced by supplying a large amount of water at one time. On the other hand, as a result of diligent studies, the inventor of the present application has found that the detergency is enhanced by increasing the linear velocity of water to increase the energy of water. In order to increase the linear velocity of water, it is necessary to reduce the amount of water supplied at one time. However, when the amount of water is small, water cannot flow into the beverage transfer path 70 due to the resistance in the beverage transfer path 70.
　そこで、本実施形態では、制御装置８０は、水とガスとが飲料移送路７０に交互に供給されるように水開閉弁９１及びガス開閉弁６１の少なくとも一方を制御する。具体的には、制御装置８０は、水供給路９０から飲料移送路７０に第１の量の水が供給されるようにガス開閉弁６１及び水開閉弁９１の少なくとも一方を制御することと、ガス供給路６０から飲料移送路７０にガスが供給されるようにガス開閉弁６１及び水開閉弁９１の少なくとも一方を制御することとを交互に繰り返す水弾制御を実行する。 Therefore, in the present embodiment, the control device 80 controls at least one of the water on-off valve 91 and the gas on-off valve 61 so that water and gas are alternately supplied to the beverage transfer path 70. Specifically, the control device 80 controls at least one of the gas on-off valve 61 and the water on-off valve 91 so that the first amount of water is supplied from the water supply path 90 to the beverage transfer path 70. Water bullet control is performed by alternately repeating controlling at least one of the gas on-off valve 61 and the water on-off valve 91 so that gas is supplied from the gas supply path 60 to the beverage transfer path 70.
　水弾制御では、飲料移送路７０に水とガスとが間欠的に供給され、いわゆる水弾洗浄が行われる。このとき、ガスが水を押し出すように機能するため、飲料移送路７０内に少量の水を流すことができる。したがって、水の線速を速めることができ、飲料供給システム１の飲料の流路を高い洗浄力で効率的に洗浄することができる。 In the water bullet control, water and gas are intermittently supplied to the beverage transfer path 70, and so-called water bullet cleaning is performed. At this time, since the gas functions to push out water, a small amount of water can flow into the beverage transfer path 70. Therefore, the linear velocity of water can be increased, and the flow path of the beverage of the beverage supply system 1 can be efficiently cleaned with high detergency.
　表１は、水弾制御において第１の量を変化させたときの洗浄後の汚れ度を示す。図４は、水弾制御における第１の量と洗浄後の汚れ度との関係を示す図である。この実験では、水開閉弁９１を開き且つガス開閉弁６１を閉じる時間（水開閉弁９１の開時間）、すなわち、水弾制御における一回当たりの水の供給時間を変化させることによって第１の量を変化させた。水の供給時間が長いほど、第１の量は多くなる。第１の量は、水弾制御における一回当たりの水の供給量に相当する。 Table 1 shows the degree of contamination after cleaning when the first amount is changed in water bullet control. FIG. 4 is a diagram showing the relationship between the first amount in water bullet control and the degree of contamination after cleaning. In this experiment, the first method is to change the time for opening the water on-off valve 91 and closing the gas on-off valve 61 (opening time for the water on-off valve 91), that is, the water supply time per water bullet control. The amount was changed. The longer the water supply time, the higher the first amount. The first amount corresponds to the amount of water supplied at one time in the water bullet control.

　例１では、水開閉弁９１の開時間が２．０秒に設定され、第１の量が２４ｍｌとなった。また、例１では、水開閉弁９１を閉じ且つガス開閉弁６１を開く時間（ガス開閉弁６１の開時間）、すなわち、水弾制御における一回当たりのガスの供給時間が２．０秒に設定された。 In Example 1, the opening time of the water on-off valve 91 was set to 2.0 seconds, and the first amount was 24 ml. Further, in Example 1, the time for closing the water on-off valve 91 and opening the gas on-off valve 61 (opening time for the gas on-off valve 61), that is, the gas supply time per time in the water bullet control is 2.0 seconds. It was set.
　例２では、水開閉弁９１の開時間が３．０秒に設定され、第１の量が４６ｍｌとなった。また、例２では、ガス開閉弁６１の開時間が３．０秒に設定された。 In Example 2, the opening time of the water on-off valve 91 was set to 3.0 seconds, and the first amount was 46 ml. Further, in Example 2, the opening time of the gas on-off valve 61 was set to 3.0 seconds.
　例３では、水開閉弁９１の開時間が５．０秒に設定され、第１の量が８４ｍｌとなった。また、例３では、ガス開閉弁６１の開時間が５．０秒に設定された。 In Example 3, the opening time of the water on-off valve 91 was set to 5.0 seconds, and the first amount was 84 ml. Further, in Example 3, the opening time of the gas on-off valve 61 was set to 5.0 seconds.
　水弾制御による洗浄力が高いほど、飲料の流路内の汚れが除去され、洗浄後の汚れ度が低くなる。表１及び図４から分かるように、第１の量を少なくするほど、水の線速を速めることができ、ひいては洗浄力を高めることができる。 The higher the cleaning power by the water bullet control, the more dirt is removed in the flow path of the beverage, and the lower the degree of dirt after cleaning. As can be seen from Table 1 and FIG. 4, the smaller the first amount, the faster the linear velocity of water, and thus the detergency can be increased.
　しかしながら、第１の量が２４ｍｌ未満である場合には、飲料ディスペンサ３０のコック３２から水が排出されているか否かをユーザが判別することが困難となる。すなわち、第１の量が２４ｍｌ未満である場合には、飲料供給システム１の洗浄が完了したか否かをユーザが判別することが困難となる。この結果、ユーザがコック３２を閉じるタイミングを間違えるおそれがある。 However, if the first amount is less than 24 ml, it becomes difficult for the user to determine whether or not water is being discharged from the cock 32 of the beverage dispenser 30. That is, when the first amount is less than 24 ml, it becomes difficult for the user to determine whether or not the cleaning of the beverage supply system 1 is completed. As a result, the user may make a mistake in closing the cock 32.
　飲料供給システム１の洗浄が完了する前にユーザがコック３２を閉じた場合には、飲料供給システム１の洗浄が不十分になると共に、飲料の流路に水が残される。一方、飲料供給システム１の洗浄が完了した後もコック３２が開かれている場合には、ガスのみが供給され続け、ガスが浪費される。このため、第１の量を２４ｍｌ未満に設定することは洗浄装置の使い勝手を低下させる。 If the user closes the cock 32 before the cleaning of the beverage supply system 1 is completed, the cleaning of the beverage supply system 1 becomes insufficient and water is left in the flow path of the beverage. On the other hand, if the cock 32 is opened even after the cleaning of the beverage supply system 1 is completed, only the gas is continuously supplied and the gas is wasted. Therefore, setting the first amount to less than 24 ml reduces the usability of the cleaning device.
　また、第１の量が多過ぎると、水弾制御における水の線速が、連続的に水を供給するときの水の流速に近くなり、洗浄力が低下する。このため、第１の量は、例えば、２４ｍｌ～１００ｍｌに設定される。或いは、第１の量は２４ｍｌ～９０ｍｌに設定される。或いは、第１の量は２４ｍｌ～８０ｍｌに設定される。或いは、第１の量は２４ｍｌ～７０ｍｌに設定される。或いは、第１の量は２４ｍｌ～６０ｍｌに設定される。或いは、第１の量は２４ｍｌ～５０ｍｌに設定される。或いは、第１の量は２４ｍｌ～４０ｍｌに設定される。或いは、第１の量は２４ｍｌ～３０ｍｌに設定される。最も好ましくは、第１の量は２４ｍｌに設定される。 Further, if the first amount is too large, the linear velocity of water in the water bullet control becomes close to the flow velocity of water when continuously supplying water, and the detergency decreases. Therefore, the first amount is set to, for example, 24 ml to 100 ml. Alternatively, the first amount is set to 24 ml to 90 ml. Alternatively, the first amount is set to 24 ml-80 ml. Alternatively, the first amount is set to 24 ml to 70 ml. Alternatively, the first amount is set to 24 ml to 60 ml. Alternatively, the first amount is set to 24 ml to 50 ml. Alternatively, the first amount is set to 24 ml-40 ml. Alternatively, the first amount is set to 24 ml to 30 ml. Most preferably, the first amount is set to 24 ml.

　以下、図５のフローチャートを参照して、上述した制御について説明する。図５は、第一実施形態における洗浄処理の制御ルーチンを示すフローチャートである。本制御ルーチンは制御装置８０（具体的にはプロセッサ８３）によって繰り返し実行される。 <Washing process>
Hereinafter, the above-described control will be described with reference to the flowchart of FIG. FIG. 5 is a flowchart showing a control routine of the cleaning process according to the first embodiment. This control routine is repeatedly executed by the control device 80 (specifically, the processor 83).
　最初に、ステップＳ１０１において、制御装置８０は、ユーザによって洗浄モードが選択されたか否かを判定する。ユーザは入力装置を介して洗浄モードを選択する。入力装置は、制御装置８０に電気的に接続され、例えば制御ボックス４０の外面に設けられたボタン４４（図１参照）として構成される。制御装置８０は入力装置の出力信号に基づいて洗浄モードの選択の有無を判定する。ステップＳ１０１において洗浄モードが選択されなかったと判定された場合、本制御ルーチンは終了する。 First, in step S101, the control device 80 determines whether or not the cleaning mode has been selected by the user. The user selects the cleaning mode via the input device. The input device is electrically connected to the control device 80 and is configured as, for example, a button 44 (see FIG. 1) provided on the outer surface of the control box 40. The control device 80 determines whether or not the cleaning mode is selected based on the output signal of the input device. If it is determined in step S101 that the cleaning mode has not been selected, the control routine ends.
　一方、ステップＳ１０１において洗浄モードが選択されたと判定された場合、本制御ルーチンはステップＳ１０２に進む。ステップＳ１０２では、制御装置８０は、水供給路９０から飲料移送路７０に第１の量の水が供給されるように水開閉弁９１を開き且つガス開閉弁６１を閉じる。第１の量は、予め定められ、上述した範囲内の値に設定される。 On the other hand, if it is determined in step S101 that the cleaning mode has been selected, the control routine proceeds to step S102. In step S102, the control device 80 opens the water on-off valve 91 and closes the gas on-off valve 61 so that the first amount of water is supplied from the water supply path 90 to the beverage transfer path 70. The first amount is predetermined and set to a value within the above range.
　具体的には、水供給路９０から飲料移送路７０に第１の量の水が供給されるように第１の時間が実験等によって予め定められ、制御装置８０は第１の時間だけ水開閉弁９１を開き且つガス開閉弁６１を閉じる。本実施形態では、制御装置８０は第１の時間だけ水開閉弁９１及びガス開閉弁６１に電力を供給する。なお、第１の量に対応する第１の時間は、供給される水の圧力、水供給路９０の断面積等に応じて変化する。このため、第１の時間は洗浄装置の構成及び設定に応じて洗浄装置毎に予め設定される。 Specifically, a first time is predetermined by an experiment or the like so that a first amount of water is supplied from the water supply path 90 to the beverage transfer path 70, and the control device 80 opens and closes the water only for the first time. The valve 91 is opened and the gas on-off valve 61 is closed. In the present embodiment, the control device 80 supplies electric power to the water on-off valve 91 and the gas on-off valve 61 only for the first time. The first time corresponding to the first amount changes according to the pressure of the supplied water, the cross-sectional area of the water supply path 90, and the like. Therefore, the first time is preset for each cleaning device according to the configuration and setting of the cleaning device.
　次いで、ステップＳ１０３において、制御装置８０は、水開閉弁９１を閉じ、ガス開閉弁６１を開く。具体的には、制御装置８０は第２の時間だけ水開閉弁９１を閉じ且つガス開閉弁６１を開く。本実施形態では、制御装置８０は第２の時間だけ水開閉弁９１及びガス開閉弁６１に電力を供給しない。第２の時間は、予め定められ、例えば１～１０秒に設定される。基本的に、第１の量が多くなるほど、水を流すために必要なガスの量は多くなる。このため、第２の時間は、第１の時間との差が１秒未満になるように設定されてもよい。 Next, in step S103, the control device 80 closes the water on-off valve 91 and opens the gas on-off valve 61. Specifically, the control device 80 closes the water on-off valve 91 and opens the gas on-off valve 61 for a second time. In the present embodiment, the control device 80 does not supply electric power to the water on-off valve 91 and the gas on-off valve 61 for the second time. The second time is predetermined and is set to, for example, 1 to 10 seconds. Basically, the greater the first amount, the greater the amount of gas required to flush the water. Therefore, the second time may be set so that the difference from the first time is less than 1 second.
　次いで、ステップＳ１０４において、制御装置８０は実行回数Ｎを更新する。具体的には、制御装置８０は現在の実行回数Ｎに１を加算することによって新たな実行回数Ｎを算出する。本制御ルーチンが開始されるときの実行回数Ｎの初期値はゼロである。 Next, in step S104, the control device 80 updates the number of executions N. Specifically, the control device 80 calculates a new number of executions N by adding 1 to the current number of executions N. The initial value of the number of executions N when this control routine is started is zero.
　次いで、ステップＳ１０５において、制御装置８０は、実行回数Ｎが閾値回数Ｎｔｈ以上であるか否かを判定する。閾値回数Ｎｔｈは予め定められる。ステップＳ１０５において実行回数Ｎが閾値回数Ｎｔｈ未満であると判定された場合、本制御ルーチンはステップＳ１０２に戻る。すなわち、水弾制御が継続される。 Next, in step S105, the control device 80 determines whether or not the number of executions N is equal to or greater than the threshold number of times Nth. The threshold number Nth is predetermined. If it is determined in step S105 that the number of executions N is less than the threshold number Nth, the control routine returns to step S102. That is, water bullet control is continued.
　一方、ステップＳ１０５において実行回数Ｎが閾値回数Ｎｔｈ以上であると判定された場合、本制御ルーチンは終了する。すなわち、水弾制御が終了する。 On the other hand, if it is determined in step S105 that the number of executions N is equal to or greater than the threshold number Nth, this control routine ends. That is, the water bullet control ends.
　なお、ステップＳ１０２がステップＳ１０３とステップＳ１０４との間に実行されてもよい。すなわち、水弾制御においてガスの供給が水の供給よりも先に行われてもよい。 Note that step S102 may be executed between step S103 and step S104. That is, in the water bullet control, the gas supply may be performed before the water supply.
＜第二実施形態＞
　第二実施形態に係る洗浄装置は、基本的に第一実施形態における洗浄装置と同様である。このため、以下、本発明の第二実施形態について、第一実施形態と異なる部分を中心に説明する。 <Second embodiment>
The cleaning device according to the second embodiment is basically the same as the cleaning device according to the first embodiment. Therefore, the second embodiment of the present invention will be described below focusing on parts different from the first embodiment.
　図６は、本発明の第二実施形態に係る洗浄装置の構成を概略的に示す図である。図６には、図２と同様に、制御ボックス４０の内部が示されている。 FIG. 6 is a diagram schematically showing the configuration of the cleaning device according to the second embodiment of the present invention. FIG. 6 shows the inside of the control box 40 as in FIG.
　第二実施形態では、洗浄装置は流量センサ４５を更に備える。流量センサ４５は、制御ボックス４０内に配置され、制御ボックス４０によって外部から隠される。具体的には、流量センサ４５は、水供給路９０に配置され、水供給路９０を流れる水の流量を検出する。本実施形態では、流量センサ４５は水開閉弁９１及び水逆止弁９２よりも下流側の水供給路９０に配置される。流量センサ４５は制御装置８０に電気的に接続され、流量センサ４５の出力は制御装置８０に入力される。 In the second embodiment, the cleaning device further includes a flow rate sensor 45. The flow rate sensor 45 is arranged inside the control box 40 and is hidden from the outside by the control box 40. Specifically, the flow rate sensor 45 is arranged in the water supply path 90 and detects the flow rate of water flowing through the water supply path 90. In the present embodiment, the flow rate sensor 45 is arranged in the water supply path 90 on the downstream side of the water on-off valve 91 and the water check valve 92. The flow rate sensor 45 is electrically connected to the control device 80, and the output of the flow rate sensor 45 is input to the control device 80.
　第一実施形態では、水供給路９０から飲料移送路７０に第１の量の水が供給されるように第１の時間が実験等によって予め定められ、制御装置８０は第１の時間だけ水開閉弁９１を開き且つガス開閉弁６１を閉じる。しかしながら、供給される水の圧力が初期設定から変化した場合には、第１の時間に対応する第１の量が変化する。このため、水弾制御において所望の量の水を飲料移送路７０に供給できないおそれがある。 In the first embodiment, the first time is predetermined by an experiment or the like so that the first amount of water is supplied from the water supply path 90 to the beverage transfer path 70, and the control device 80 is water only for the first time. The on-off valve 91 is opened and the gas on-off valve 61 is closed. However, if the pressure of the supplied water changes from the initial setting, the first amount corresponding to the first time will change. Therefore, there is a possibility that a desired amount of water cannot be supplied to the beverage transfer path 70 in the water bullet control.
　そこで、第二実施形態では、制御装置８０は、流量センサ４５の出力に基づいて水弾制御において水供給路９０から飲料移送路７０に供給された水の量の推定値を算出し、推定値が第１の量に達するようにガス開閉弁６１及び水開閉弁９１の少なくとも一方を制御する。すなわち、制御装置８０は、水弾制御において水供給路９０から飲料移送路７０に供給された水の量の推定値が第１の量に達したときに水開閉弁９１を閉じ且つガス開閉弁６１を開く。このことによって、水弾制御において飲料移送路７０に供給される水の量が変動することを抑制することができ、ひいては水弾制御において洗浄力が低下することを抑制することができる。 Therefore, in the second embodiment, the control device 80 calculates an estimated value of the amount of water supplied from the water supply path 90 to the beverage transfer path 70 in the water bullet control based on the output of the flow rate sensor 45, and the estimated value. Controls at least one of the gas on-off valve 61 and the water on-off valve 91 so that the amount reaches the first amount. That is, the control device 80 closes the water on-off valve 91 and the gas on-off valve when the estimated value of the amount of water supplied from the water supply path 90 to the beverage transfer path 70 reaches the first amount in the water bullet control. Open 61. As a result, it is possible to suppress fluctuations in the amount of water supplied to the beverage transfer path 70 in the water bullet control, and it is possible to suppress a decrease in detergency in the water bullet control.
＜洗浄処理＞
　図７は、第二実施形態における洗浄処理の制御ルーチンを示すフローチャートである。本制御ルーチンは制御装置８０（具体的にはプロセッサ８３）によって繰り返し実行される。 <Washing process>
FIG. 7 is a flowchart showing a control routine of the cleaning process according to the second embodiment. This control routine is repeatedly executed by the control device 80 (specifically, the processor 83).
　最初に、ステップＳ２０１において、図５のステップＳ１０１と同様に、制御装置８０は、ユーザによって洗浄モードが選択されたか否かを判定する。洗浄モードが選択されなかったと判定された場合、本制御ルーチンは終了する。 First, in step S201, similarly to step S101 of FIG. 5, the control device 80 determines whether or not the cleaning mode has been selected by the user. If it is determined that the wash mode has not been selected, this control routine ends.
　一方、ステップＳ２０１において洗浄モードが選択されたと判定された場合、本制御ルーチンはステップＳ２０２に進む。ステップＳ２０２では、制御装置８０は、水開閉弁９１を開き、ガス開閉弁６１を閉じる。本実施形態では、制御装置８０は水開閉弁９１及びガス開閉弁６１に電力を供給する。 On the other hand, if it is determined in step S201 that the cleaning mode has been selected, the control routine proceeds to step S202. In step S202, the control device 80 opens the water on-off valve 91 and closes the gas on-off valve 61. In the present embodiment, the control device 80 supplies electric power to the water on-off valve 91 and the gas on-off valve 61.
　次いで、ステップＳ２０３において、制御装置８０は流量センサ４５の出力を取得する。 Next, in step S203, the control device 80 acquires the output of the flow rate sensor 45.
　次いで、ステップＳ２０４において、制御装置８０は、流量センサ４５の出力に基づいて、水弾制御において水供給路９０から飲料移送路７０に供給された水の量の推定値ＥＡを算出する。具体的には、制御装置８０は、流量センサ４５によって検出された水の流量を積算することによって水の量の推定値ＥＡを算出する。 Next, in step S204, the control device 80 calculates an estimated value EA of the amount of water supplied from the water supply path 90 to the beverage transfer path 70 in the water bullet control based on the output of the flow rate sensor 45. Specifically, the control device 80 calculates the estimated value EA of the amount of water by integrating the flow rate of water detected by the flow rate sensor 45.
　次いで、ステップＳ２０５において、制御装置８０は、水の量の推定値ＥＡが第１の量Ａ１以上であるか否かを判定する。第１の量は、予め定められ、上述した範囲内の値に設定される。 Next, in step S205, the control device 80 determines whether or not the estimated value EA of the amount of water is equal to or greater than the first amount A1. The first amount is predetermined and set to a value within the above range.
　ステップＳ２０５において水の量の推定値ＥＡが第１の量Ａ１未満であると判定された場合、本制御ルーチンはステップＳ２０３に戻る。すなわち、水の供給が継続される。 If it is determined in step S205 that the estimated value EA of the amount of water is less than the first amount A1, the control routine returns to step S203. That is, the water supply is continued.
　一方、ステップＳ２０５において水の量の推定値ＥＡが第１の量Ａ１以上であると判定された場合、本制御ルーチンはステップＳ２０６に進む。 On the other hand, if it is determined in step S205 that the estimated value EA of the amount of water is equal to or greater than the first amount A1, the control routine proceeds to step S206.
　ステップＳ２０６では、制御装置８０は、水開閉弁９１を閉じ、ガス開閉弁６１を開く。具体的には、制御装置８０は第２の時間だけ水開閉弁９１を閉じ且つガス開閉弁６１を開く。本実施形態では、制御装置８０は第２の時間だけ水開閉弁９１及びガス開閉弁６１に電力を供給しない。第２の時間は、予め定められ、例えば１～７秒に設定される。 In step S206, the control device 80 closes the water on-off valve 91 and opens the gas on-off valve 61. Specifically, the control device 80 closes the water on-off valve 91 and opens the gas on-off valve 61 for a second time. In the present embodiment, the control device 80 does not supply electric power to the water on-off valve 91 and the gas on-off valve 61 for the second time. The second time is predetermined and is set to, for example, 1 to 7 seconds.
　次いで、ステップＳ２０７において、制御装置８０は実行回数Ｎを更新する。具体的には、制御装置８０は現在の実行回数Ｎに１を加算することによって新たな実行回数Ｎを算出する。本制御ルーチンが開始されるときの実行回数Ｎの初期値はゼロである。 Next, in step S207, the control device 80 updates the number of executions N. Specifically, the control device 80 calculates a new number of executions N by adding 1 to the current number of executions N. The initial value of the number of executions N when this control routine is started is zero.
　次いで、ステップＳ２０８において、制御装置８０は、実行回数Ｎが閾値回数Ｎｔｈ以上であるか否かを判定する。閾値回数Ｎｔｈは予め定められる。ステップＳ２０８において実行回数Ｎが閾値回数Ｎｔｈ未満であると判定された場合、本制御ルーチンはステップＳ２０２に戻る。すなわち、水弾制御が継続される。 Next, in step S208, the control device 80 determines whether or not the number of executions N is equal to or greater than the threshold number of times Nth. The threshold number Nth is predetermined. If it is determined in step S208 that the number of executions N is less than the threshold number Nth, the control routine returns to step S202. That is, water bullet control is continued.
　一方、ステップＳ２０８において実行回数Ｎが閾値回数Ｎｔｈ以上であると判定された場合、本制御ルーチンは終了する。すなわち、水弾制御が終了する。 On the other hand, if it is determined in step S208 that the number of executions N is equal to or greater than the threshold number Nth, this control routine ends. That is, the water bullet control ends.
　なお、ステップＳ２０２～ステップＳ２０５がステップＳ２０６とステップＳ２０７との間に実行されてもよい。すなわち、水弾制御においてガスの供給が水の供給よりも先に行われてもよい。 Note that steps S202 to S205 may be executed between steps S206 and S207. That is, in the water bullet control, the gas supply may be performed before the water supply.
＜その他の実施形態＞
　以上、本発明に係る好適な実施形態を説明したが、本発明はこれら実施形態に限定されるものではなく、特許請求の範囲の記載内で様々な修正及び変更を施すことができる。 <Other Embodiments>
Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and modifications can be made within the scope of the claims.
　例えば、水供給路９０から飲料移送路７０に供給される水の圧力が、ガス供給路６０から飲料移送路７０に供給されるガスの圧力よりも高い場合には、ガス開閉弁６１及び水開閉弁９１の両方が開いているときに水が飲料移送路７０に供給される。このため、この場合、水弾制御において、ガス開閉弁６１が常に開かれ、水開閉弁９１の開閉のみが制御装置８０によって制御されてもよい。具体的には、制御装置８０は、水弾制御において、水供給路９０から飲料移送路７０に第１の量の水が供給されるように水開閉弁９１を開くことと、ガス供給路６０から飲料移送路７０にガスが供給されるように水開閉弁９１を閉じることとを交互に繰り返す。また、この場合、ガス開閉弁６１は省略されてもよい。 For example, when the pressure of the water supplied from the water supply path 90 to the beverage transfer path 70 is higher than the pressure of the gas supplied from the gas supply path 60 to the beverage transfer path 70, the gas on-off valve 61 and the water opening / closing Water is supplied to the beverage transfer path 70 when both valves 91 are open. Therefore, in this case, in the water bullet control, the gas on-off valve 61 may always be opened, and only the opening and closing of the water on-off valve 91 may be controlled by the control device 80. Specifically, the control device 80 opens the water on-off valve 91 so that the first amount of water is supplied from the water supply path 90 to the beverage transfer path 70 in the water bullet control, and the gas supply path 60. The water on-off valve 91 is closed alternately so that the gas is supplied to the beverage transfer path 70. Further, in this case, the gas on-off valve 61 may be omitted.
　また、ガス供給路６０から飲料移送路７０に供給されるガスの圧力が、水供給路９０から飲料移送路７０に供給される水の圧力よりも高い場合には、ガス開閉弁６１及び水開閉弁９１の両方が開いているときにガスが飲料移送路７０に供給される。このため、この場合、水弾制御において、水開閉弁９１が常に開かれ、ガス開閉弁６１の開閉のみが制御装置８０によって制御されてもよい。具体的には、制御装置８０は、水弾制御において、水供給路９０から飲料移送路７０に第１の量の水が供給されるようにガス開閉弁６１を閉じることと、ガス供給路６０から飲料移送路７０にガスが供給されるようにガス開閉弁６１を開くこととを交互に繰り返す。また、この場合、水開閉弁９１は省略されてもよい。 Further, when the pressure of the gas supplied from the gas supply path 60 to the beverage transfer path 70 is higher than the pressure of the water supplied from the water supply path 90 to the beverage transfer path 70, the gas on-off valve 61 and the water on-off valve 61 are opened and closed. Gas is supplied to the beverage transfer path 70 when both valves 91 are open. Therefore, in this case, in the water bullet control, the water on-off valve 91 may always be opened, and only the opening and closing of the gas on-off valve 61 may be controlled by the control device 80. Specifically, in the water bullet control, the control device 80 closes the gas on-off valve 61 so that the first amount of water is supplied from the water supply path 90 to the beverage transfer path 70, and the gas supply path 60. The gas on-off valve 61 is opened alternately so that the gas is supplied to the beverage transfer path 70. Further, in this case, the water on-off valve 91 may be omitted.
　また、水供給路９０は飲料移送路７０（例えばディスペンスヘッド５０近傍の飲料移送路７０）に直接接続されてもよい。また、水供給路９０は、飲料供給システム１の洗浄時にのみ、ガス供給路６０と統合され又は飲料移送路７０に直接接続されてもよい。 Further, the water supply path 90 may be directly connected to the beverage transfer path 70 (for example, the beverage transfer path 70 near the dispense head 50). Further, the water supply path 90 may be integrated with the gas supply path 60 or directly connected to the beverage transfer path 70 only when the beverage supply system 1 is washed.
　また、ガス供給路６０は、飲料の供給時にディスペンスヘッド５０に接続され、飲料供給システム１の洗浄時に飲料移送路７０に直接接続されてもよい。また、飲料を移送するために飲料収容容器２０にガスを供給するガス供給路６０とは別のガス供給路が飲料供給システム１の洗浄時に飲料移送路７０に直接接続されてもよい。 Further, the gas supply path 60 may be connected to the dispense head 50 when the beverage is supplied, and may be directly connected to the beverage transfer path 70 when the beverage supply system 1 is washed. Further, a gas supply path different from the gas supply path 60 that supplies gas to the beverage storage container 20 for transferring the beverage may be directly connected to the beverage transfer path 70 at the time of cleaning the beverage supply system 1.
　また、ガス逆止弁６２、水逆止弁９２及び水減圧弁１１０の少なくとも一つは省略されてもよい。また、飲料ディスペンサ３０は、飲料収容容器２０から移送された飲料を冷却するように構成されていなくてもよい。この場合、飲料ディスペンサ３０はコック３２のみから構成されてもよい。 Further, at least one of the gas check valve 62, the water check valve 92, and the water pressure reducing valve 110 may be omitted. Further, the beverage dispenser 30 may not be configured to cool the beverage transferred from the beverage storage container 20. In this case, the beverage dispenser 30 may be composed of only the cock 32.
　また、ガス開閉弁６１は非通電時にガス供給路６０を閉じ且つ通電時にガス供給路６０を開くように構成されていてもよい。同様に、水開閉弁９１は非通電時に水供給路９０を開き且つ通電時に水供給路９０を閉じるように構成されていてもよい。 Further, the gas on-off valve 61 may be configured to close the gas supply path 60 when not energized and open the gas supply path 60 when energized. Similarly, the water on-off valve 91 may be configured to open the water supply path 90 when not energized and close the water supply path 90 when energized.
