- FIG. 13 shows the inside of the control box 40 as in FIG. 2.
- the beverage transfer path 70 is connected to the control box 40 by a pair of joints 47.
- the cleaning device further includes a warning device 46.
- the cleaning device further includes a capacitance type sensor 48.
- the capacitance type sensor 48 is arranged inside the control box 40 and is hidden from the outside by the control box 40. Specifically, the capacitive sensor 48 is arranged on the beverage transfer path 70 between the beverage storage container 20 and the beverage dispenser 30.
- the user can easily obtain a desired amount of beverage by pouring the beverage from the beverage dispenser or 30 into the container.
- gas is supplied from the beverage container 20 to the beverage dispenser 30, and the gas is ejected from the beverage dispenser 30.
- the beverage poured into the container is scattered around. Therefore, it is desirable to be able to detect that the beverage contained in the beverage container 20 has been exhausted.
- the capacitance type sensor 48 detects the state in the beverage transfer path 70, and specifically detects the presence or absence of liquid in the beverage transfer path 70.
- the capacitance type sensor 48 is a so-called non-contact type sensor, and is attached around, for example, a beverage transfer path 70. Therefore, the capacitance type sensor 48 can detect the state in the beverage transfer path 70 without coming into contact with the beverage in the beverage transfer path 70. This makes it possible to prevent the beverage from being contaminated by the sensor in the beverage transfer path 70.
- the beverage passes through the beverage transfer path 70.
- gas is supplied from the beverage storage container 20 to the beverage dispenser 30, and the gas passes through the beverage transfer path 70. Since the beverage and the gas have different dielectric constants, when the fluid in the beverage transfer path 70 changes from the beverage to the gas at the position where the capacitance sensor 48 is arranged, it is detected by the capacitance sensor 48. The value of capacitance changes. Therefore, the capacitance type sensor 48 can detect the presence or absence of a beverage in the beverage storage container 20.

Therefore, by causing the warning device 46 to output a warning as described above, it is possible to prevent the beverage poured into the container from being scattered around due to the gas ejected from the cock 32.
- the beverage transfer path 70 is not automatically shut off by the on-off valve or the like in order to stop the supply of the beverage. Therefore, it is possible to prevent the beverage from being contaminated by the on-off valve or the like arranged in the beverage transfer path 70.
- the capacitance type sensor 48 erroneously detects the presence or absence of a beverage in the beverage transfer path 70, it is left to the user to determine whether or not to stop the supply of the beverage. Therefore, when the depletion of the beverage is detected immediately after the beverage storage container 20 is replaced, the user can ignore the warning and continue the supply of the beverage. In addition, an operation for releasing the shutoff of the beverage transfer path 70 by an on-off valve or the like becomes unnecessary. Therefore, by notifying the user of the depletion of the beverage by a warning, it is possible to reduce the discomfort of the user caused by the false detection of the presence or absence of the beverage.

図1は、本発明の第一実施形態に係る飲料供給システムの洗浄装置が適用される飲料供給システムの構成を概略的に示す図である。飲料供給システム1は、ガス供給源10、飲料収容容器20及び飲料ディスペンサ30を備える。飲料供給システム1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飲料ディスペンサ30から外部に供給する。飲料供給システム1のユーザ(以下、単に「ユーザ」と称する)は飲料ディスペンサ30から容器に飲料を注ぐことによって所望の量の飲料を容易に得ることができる。
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。
以下、図4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4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。
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。
図5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。
第三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、本発明の第三実施形態について、第一実施形態と異なる部分を中心に説明する。
図6は、第三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。
第四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、本発明の第四実施形態について、第一実施形態と異なる部分を中心に説明する。
図8は、第四実施形態におけるリンス制御の制御ルーチンを示すフローチャートである。最初に、ステップS401において、制御装置80は、水開閉弁91を開き、ガス開閉弁61を閉じる。具体的には、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。
図9は、第四実施形態における水弾制御の制御ルーチンを示すフローチャートである。最初に、ステップS501において、制御装置80は、水開閉弁91を開き、ガス開閉弁61を閉じる。具体的には、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。
第五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、本発明の第五実施形態について、第一実施形態と異なる部分を中心に説明する。
図12は、第五実施形態におけるリンス制御の制御ルーチンを示すフローチャートである。最初に、ステップS601において、制御装置80は、水開閉弁91を開き、ガス開閉弁61を閉じる。具体的には、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。
第六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、本発明の第六実施形態について、第一実施形態と異なる部分を中心に説明する。
以下、図14のフローチャートを参照して、上述した制御について詳細に説明する。図4は、第六実施形態における警告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。
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。
