Description

【０００１】
【発明の属する技術分野】
この発明は、水道水の供給を受けていったん水リザーバに貯留しそこから配水して冷水、温水、炭酸水等に加工した後、飲料原料と混合調理してカップに供給して販売に供する自動販売機の水回路に関する。
【０００２】
【従来の技術】
従来の自動販売機は、例えば、インスタントコーヒ、紅茶などの粉末原料を温水と混合調理して販売するホット飲料販売装置と、種々のシロップを冷水、または炭酸水のいずれかで希釈して販売するコールド飲料販売装置とを一体にした販売装置であり、飲料水（水道水）は機外から水入口弁を介して水リザーバに取り入れられそこでいったん貯蔵され、その一部は製氷機に供給されて、製氷されて製氷機内の氷貯蔵タンクに貯蔵される。また、別の一部は水ポンプを介して、ホット飲料用に温水を供給する温水タンク、およびコールド飲料用の冷水、炭酸水の水回路に配水される。
【０００３】
この飲料水を機外から機内に採り入れるには、水リザーバの水位スイッチと連動して開閉する水入口弁により制御される。すなはち、水リザーバ内のフロートに連動して開閉するスイッチは、上から順に上上限スイッチ、および高水位スイッチ、低水位スイッチが設けられており、高水位スイッチが動作する水位以下に水位がさがれば、水入口弁を開成して給水を開始し、高水位スイッチが動作し更に上上限スイッチが動作してから水入口弁を閉鎖して給水を停止するようにしている。この給水開始から停止までの間に給水される水量は、その自動販売機に使用されているカップの中で最も小さいカップに一杯分の飲料水を給水する量に略等しい量に設定される。
【０００４】
このことは特にコールド飲料を販売する際に供給する氷片を製氷する製氷機にとっては重要なことである。すなはち、製氷機はそれ自身では水位調節機能を持っておらず、製氷機の水を氷に凝縮させるエバポレータ内の水位は水リザーバの水位と同じになっている。良質の氷片を製氷するためにはエバポレータ内の水位は常に略一定水位に保たれることが望ましい。エバポレータ内の水位が高過ぎたり、低過ぎたりすると柔らかくてみぞれ状の氷になったり、固すぎてエバポレータ内で異音を発し、駆動装置を過負荷にする氷になったりする。
【０００５】
【発明が解決しようとする課題】
従来の構成では、水道水の採り入れは、水リザーバの高水位スイッチと上上限スイッチの動作範囲で水入口弁を開閉して行っていたために、例えば水漏れがあった場合には、上上限スイッチが動作しないので機内に漏水が溢れる恐れがあり、機内に漏水検出器を設けて対処している。
【０００６】
この発明は上記課題を解決するためになされたもので、その目的とするところは、水回路に漏水箇所がある場合でも水入口弁が開き放しにならない自動販売機の水回路を提供することにある。
【０００７】
【課題を解決するための手段】
請求項１記載の発明によれば、水道水の供給を受けていったん水リザーバ内に貯留しそこから配水して冷水、温水、炭酸水等に加工した後、飲料原料と混合調理してカップにより販売に供する自動販売機の水回路において、水リザーバの水位の変動に従動して昇降するフロートと、フロートが上昇してＯＮすると上上限水位を検出する上上限スイッチと、フロートが上上限水位から降下してＯＦＦすると高水位以下を検出する高水位スイッチと、を配設し、フロートが降下して高水位スイッチがＯＦＦすると水リザーバに給水を開始し、フロートが上昇して上上限スイッチがＯＮすると給水を停止する水回路であって、飲料販売等により水位が低下して高水位以下に達し水リザーバに給水が開始されると同時に作動するタイマー回路を設け、給水を開始して、正常に給水されると給水を停止する上上限水位に達するまでの時間以上の時間をタイマー回路に設定し、水リザーバに給水を開始してから給水を停止するまでの時間がタイマー回路の設定時間を越えると水道水の給水を停止し、タイマー回路の設定時間を越える前に上上限水位に達すればタイマー回路をリセットするようにした自動販売機の水回路とする。
【０００８】
請求項２記載の発明によれば、請求項１記載の自動販売機の水回路において、タイマー回路の設定時間は販売される飲料量に比例して変える自動販売機の水回路とする。
請求項３記載の発明によれば、請求項１または請求項２に記載の自動販売機の水回路において、タイマー回路は自動販売機の外扉の開成により電気的に切り離され、外扉閉鎖により復帰するようにした自動販売機の水回路とする。
【０００９】
上記構成により水回路に漏水がある場合でもタイマー回路が動作して、カップ一杯分プラスアルファを水リザーバに給水したところで給水を停止するので水入口弁が開き放しにならず漏水を制限できる。また、サービス時に外扉を開成して機内を洗浄する際にはタイマー回路を電気的に切り離すので洗浄水が使用中にタイマー回路で遮断されることはない。
【００１０】
【発明の実施の形態】
図１はこの発明の実施の形態を示すフローチャート図である。この図１において、飲料販売、または漏水により水リザーバの水位が低下してフロートが下がり、高水位スイッチをオフにすると給水開始信号が発せられて水入口弁が開き水リザーバに給水される。この時、外扉が開成しておれば、それはサービス時であるからタイマー回路は電気的に切り離して動作しないようにするが外扉が閉鎖しておればタイマー回路を入りにしてカウントを開始する。その後、水リザーバ内の水位が上昇してフロートが上昇し上上限スイッチを動作させると給水停止信号を発するが、上上限スイッチが動作する前にタイマー回路が設定時間に達した場合は、水ポンプを停止して水ポンプ以降に送水しないようにするとともに、売切り表示を出して販売停止にし、さらに水入口弁を閉鎖してそれ以上給水されないようにする。
【００１１】
なお、タイマー回路が設定時間に達する前に上上限スイッチが動作した場合は、タイマー回路をリセットするとともに、水入口弁を閉鎖して給水を停止し、次回の販売に備える。
【００１２】
【実施例】
図２はこの発明の一実施例の自動販売機の水回路図を示す。この図２において、１はインスタントコーヒ、紅茶などの粉末原料を貯留するキャニスタ、２は粉末原料をミキシングボール３に切り出すシュータ、４は温水タンク、５は水道水の給水・停止を制御する水入口弁、６は水道水を機内にいったん貯留する水リザーバ、６ａは水リザーバ６の上上限水位スイッチ、６ｂは水リザーバ６の高水位スイッチ、６ｃは水リザーバ６の低水位スイッチ、６ｄは水リザーバ６のフロート，７は水リザーバ５の水を機内の各所に配水する水ポンプ、８は冷却水槽、９は炭酸水を製造して貯留するカーボネータ、１０ａはカップ１４に冷水を供給する冷水ノズル、１０ｂはカップ１４に炭酸水を供給する炭酸水ノズル、１１は炭酸ガスボンベ、１２はシロップタンク、１３はシロップタンクのシロップの吐出量を制御するシロップバルブ、１５はシロップノズル、１６は製氷機を示す。
【００１３】
この図２において、キャニスタ１に貯留されたインスタントコーヒ、紅茶などの粉末原料を定量切り出して、シュート２を介してミキシングボール３に供給し、温水タンク４から供給される温水をミキシングボール３内で混合して販売するホット飲料販売装置と、種々のシロップを冷水、または炭酸水のいずれかで希釈して販売するコールド飲料販売装置とを一体にした販売装置であり、飲料水（水道水）は機外から水入口弁５の開成により供給されて水リザーバ６に貯蔵され、その一部は製氷機１６に供給されて、製氷されて製氷機１６内の氷貯蔵タンクに貯蔵される。
【００１４】
また、別の一部は水ポンプ７を介して、途中で冷却水槽８で冷却されてカーボネータ９と冷水ノズル１０ａに供給される。カーボネータ９に供給された水は炭酸ガスボンベ１１から送られる炭酸ガスを溶解して炭酸水になりカーボネータ９内に貯留される。
シロップは機内のシロップコンテナ１２に貯留されており、炭酸ガスボンベ１１から配管されて供給される炭酸ガスの圧力で押し出されて、途中で配管を通して冷却水槽８内で冷却されてシロップバルブ１３にまで供給されている。前記の冷却水槽８内にはシロップコンテナ、冷水の冷却配管の他にカーボネータ９等が入れられている。
【００１５】
水ポンプ７からの水は、カーボネータ９と冷水ノズル１０ａに供給される以外に温水タンク４にも供給されて、そこで温水に沸かされて貯留され、ホット飲料販売時にキャニスタ１から供給される粉末原料を溶かしてカップ１４に供給される。
一方、コールド飲料は、シロップコンテナ１２に供給される炭酸ガスの圧力で送りだされて、途中で冷却水槽８で冷却されて、シロップバルブ１３に送られ、販売時にシロップバルブ１３を開けてその先のノズル１５を通してカップ１４に注がれる。また、シロップと同時に、冷水、または炭酸水のいずれか一つがそれぞれのノズル１０ａ，１０ｂを通してカップ１４に吐出されて、カップ１４内で混合されて、販売に供される。製氷機１６で製氷されて貯留されている氷片は客の要求に応じてカップ１４に供給される。
【００１６】
コールド飲料を販売する際にカップ１４に供給される氷片を製氷する製氷機１６内の水位は製氷機１６自身で水位調整機構を持っていないので水リザーバ６の水位と同じ水位になる。製氷機１６内で良質の氷を製氷するのに適切な水位を保持するために、水リザーバ６の水位はその水リザーバ６に付属する上上限スイッチ６ａが上上限水位を検出すると水入口弁５を閉鎖して給水を止め、高水位スイッチ６ｂがフロート６ｄに連動して上下する押し板を離れて水面が高水位以下を検出すると水入口弁５を開いて給水して、常時上上限水位と高水位の範囲内に保持される。水リザーバ６の水位が上上限スイッチ６ａが動作する水位を越えてオーバーフロー水位以上に上昇すると、その水はオーバーフロー口を通して排水される。
【００１７】
低水位スイッチ６ｃは水リザーバ６に水が無くなったことを検出して信号を発するので、その場合は自動販売機の販売を中止する。
上述の水回路が水道に接続されてそこから飲料水を採り入れる動作は、飲料販売、または漏水により水リザーバ６の水位が低下してフロート６ｄが下がり、高水位スイッチ６ｂをオフにすると給水開始信号が発せられて水入口弁５が開き水リザーバ６に給水される。この時、外扉が開成しておれば、それはサービス時であるからタイマー回路は電気的に切り離して動作しないようにするが外扉が閉鎖しておればタイマー回路を入りにしてカウントを開始する。その後、水リザーバ６内の水位が上昇してフロート６ｄが上昇し上上限スイッチ６ａを動作させると給水停止信号を発するが、上上限スイッチ６ａが動作する前にタイマー回路が設定時間に達した場合は、水ポンプ７を停止して水ポンプ７以降に送水しないようにするとともに、売切り表示を出して販売停止にし、さらに水入口弁５を閉鎖してそれ以上給水されないようにする。
【００１８】
【発明の効果】
この発明によれば、水回路に漏水がある場合でも給水開始信号が発せられてからカップ一杯分プラスアルファ以上の水は給水しないので自動販売機内を水浸しにしない効果がある。
