Description

【0001】
【発明の属する技術分野】
本発明は商品収納装置に収納された商品を冷却または加熱して商品を販売するようにした自動販売機の加熱制御装置に関するものである。
【0002】
【従来の技術】
従来の自動販売機の一般的なものとしては例えば特開平06−84060号公報に示されているように、省エネルギー問題から節電化を図るために冷却装置または加熱装置が停止してから庫内ファンを停止させて、その送風による庫内からリークする熱量を低減させて省エネを行なっている。
【0003】
また、扉が開けられた場合には、庫内ファンモータを停止し外気と庫内の熱交換を抑制したり、ゾーン冷却・ゾーン加熱のため庫内ファンモータの回転数制御を行なったり、さらには、入力の少ない小型のファンモータや発熱量の少ないDCファンモータが採用されるようになっている。一方、利便性を提供する自動販売機にも、いつでもより最適な温度で商品販売できるよう、温度管理に対しても要求が厳しくなってきている。
【0004】
以下、図面を参照しながら上記従来の自動販売機の加熱制御装置を説明する。
【0005】
図17は従来の自動販売機の加熱制御装置の要部の構成を示すブロック図である。図17において、1は収納室内温度により冷却装置や加熱装置の運転を制御する庫内温度検知手段で、例えばサーミスタであり商品収納装置の下部に設けられている。2は商品を加熱するための加熱手段で、例えばヒータである。3はファンで、加熱された空気を送風するものである。31は販売状況検知手段であり、商品が販売されると計数し単位時間あたりの販売数を求めることができる。
【0006】
32は主制御部であり、庫内温度検知手段1の検出信号などが入力される入力部、ファン3の停止遅延時間などを演算する演算部、この演算のためのテーブルやプログラムおよび演算結果などを記憶する記憶部、および加熱手段2、ファン3に駆動信号を出力する出力部(いずれも図示せず)などによって構成されている。
【0007】
以上のように構成された従来の自動販売機の加熱制御装置について、以下その動作を簡単に説明する。
【0008】
主制御部32は、販売状況検知手段31により入力された販売数より単位時間あたりの販売数を求めるとともに、庫内温度検知手段1により制御される加熱手段2の停止時間の前回と今回の時間差を求める。この単位時間あたりの販売数と停止時間の前回と今回の時間差を入力条件とし、ファジィ推論により所定のプログラムにしたがってファン3の遅延時間を演算し、その結果に従って加熱手段2の停止から所定の遅延時間が経過した後に、ファン3は停止される。ファン3が停止されると庫外へのリーク熱量の低減、およびファン3の消費電力の節電による省エネが行なわれることになる。
【0009】
【発明が解決しようとする課題】
しかしながら上記のような構成では、庫内の商品温度が充分に安定していない過渡状態(例えば、電源投入後、冷却から加熱への設定変更後、商品の補充等で扉の開閉後)の場合にも庫内ファンが停止することもあり、商品温度のバラツキの要因となったり、高温の状態で庫内ファンが停止することで、加熱手段(ヒータ)周辺部の過熱、庫内ファンモータの軸受け部の温度上昇を伴い庫内ファンモータの寿命を低下させてしまうといった課題を有していた。
【0010】
本発明は、上記課題に鑑み、最適な商品温度を確保しながら、省エネを図るとともに、加熱手段(ヒータ)周辺部の過熱、庫内ファンモータの軸受け部の温度上昇を防ぎ信頼性の高い自動販売機の加熱制御装置を提供することを目的とする。
【0011】
【課題を解決するための手段】
本発明の請求項1に記載の発明は、庫内温度検知手段により検知した庫内温度に基づき庫内の商品を加熱する加熱手段への給電と前記給電の停止とを制御して加熱販売する商品の温度を商品設定温度に保つ自動販売機の加熱制御装置において、電源投入後、または冷却運転から加熱運転への設定変更後、または扉の開閉後の前記加熱手段への給電の動作回数を計数する動作回数計数手段を設け、前記動作回数計数手段の計数する給電の動作回数が予め設定された規定数に達するまでは、前記加熱手段で加熱された空気を庫内で循環させるファンを連続運転させ、前記動作回数計数手段の計数する給電の動作回数が前記規定数に達した後は、前記ファンを間欠運転させるものであり、庫内温度検知手段により加熱手段への給電の動作回数(ON/OFF)を繰り返し行なうことで商品温度は安定状態に近付いていくので、加熱手段への給電の動作回数で安定状態を判定することができ、その後ファンの間欠運転を行なうことで省エネを図るという作用を有する。
【0018】
請求項に記載の発明は、加熱手段への給電を行なっているときは、強制的にファンを連続運転させることを特徴とした請求項に記載の自動販売機の加熱制御装置であり、加熱手段が高温となるON時はファンを連続運転し商品温度を一定に確保することを優先し、また加熱手段(ヒータ)周辺部の過熱、庫内ファンモータの軸受け部の温度上昇を防ぎ、加熱手段への給電が停止されたOFF時に、ファンの間欠運転を行なうことで省エネを図るという作用を有する。
【0019】
【発明の実施の形態】
以下、本発明による自動販売機の加熱制御装置の実施の形態について、図面を参照しながら説明する。

【0034】
このときタイマー13で電源投入・設定変更・扉開閉の少なくとも一つが行なわれた時間から時間Cを計数開始する(S3)。時間Cと規定時間記憶手段14に記憶されている規定時間Dを比較判定手段15にて比較する(S4)。時間Cが規定時間Dに達した場合は、商品温度が安定していると判断しファン3を間欠運転させる(S5)。なお、(S1)にて電源投入・設定変更・扉開閉のいずれもない場合も商品温度が安定していると判断しファン3を間欠運転させる。

【0068】
例えば、冷たい商品を補充された場合、商品温度検知手段の近傍には加熱された商品があるため商品温度検知手段は安定であると判断するが、補充された冷たい商品と扉開閉により外気の影響を受け庫内温度検知手段は温度が変化し不安定であると判断する。このような場合にも、商品温度検知手段と庫内温度検知手段で状態を正確に把握でき、過渡状態や不安定な状態の時は、ファンの連続運転を行い商品の温度を早く安定させることを優先し、安定したらすぐにファンを間欠運転させ省エネを行なうことができる。

電源投入判定手段7と設定変更判定手段8と扉開閉判定手段9により電源投入・設定変更・扉開閉が行なわれたかをそれぞれ判定する(S1)。電源投入・設定変更・扉開閉の少なくとも一つが行なわれた場合は、商品温度が不安定であると判断し、ファン3を連続運転させる(S2)。加熱手段2は、庫内温度検知手段1で検知した温度と設定温度記憶手段4に記憶されている温度とを比較しON/OFFの動作を繰り返し、商品温度を設定された商品温度に安定させていく。
【0075】
商品温度検知手段24aで商品温度W1と商品温度検知手段24bで商品温度X1を読み取る(S3)。一定時間経過後、商品温度検知手段24aで商品温度W2と商品温度検知手段24bで商品温度X2を読み取る(S4)。温度変化判定手段25bで商品温度変化Y<Y=W2−W1>と商品温度変化Z<Z=X2−X1>を算出する(S5)。商品温度変化Yと規定温度変化Tを比較判定手段15eにて比較する(S6)。商品温度変化Yが規定温度変化T以下の場合、商品温度変化Zと規定温度変化Tを比較判定手段15eにて比較する(S7)。商品温度変化Yと商品温度変化Zがともに規定温度変化以下になった場合は、商品温度がいずれも安定していると判断しファン3を間欠運転させる(S8)。なお、(S1)にて電源投入・設定変更・扉開閉のいずれもない場合も商品温度が安定していると判断しファン3を間欠運転させる。

【0084】
このときタイマー13で電源投入・設定変更・扉開閉の少なくとも一つが行なわれた時間から時間Cを計数開始する(S3)。時間Cと規定時間記憶手段14に記憶されている規定時間Dを比較判定手段15fにて比較する(S4)。時間Cが規定時間Dに達した場合は、商品温度が安定していると判断し、比較判定手段5より加熱手段2への給電が行なわれているか、給電が停止されているかを読取り(S5)、給電停止の場合にはファン3を間欠運転させる(S6)。加熱手段2への給電が行なわれている場合にはファン3は連続運転を行なう。
