【発明の属する技術分野】
この発明は、冷蔵庫の制御装置に関するものである。
【0002】
【従来の技術】
従来の冷蔵庫の制御では、扉閉め忘れを知らせるアラームは扉が閉められるまで鳴り続け、庫内灯は扉が閉められるまで点灯し続けるのが一般的であった。
【0003】
【発明が解決しようとする課題】
従来の冷蔵庫の制御は以上のように行われるので、扉開閉によりON/OFFするスイッチが途中故障した場合、扉を閉めた状態であっても扉閉め忘れを知らせるアラームは鳴り続け、アラームを止める為には冷蔵庫の電源をOFFする方法しかなく、庫内の食品温度に影響を与えるという問題点があった。
【0004】
また、同じく扉開閉によりON/OFFするスイッチが途中故障した場合、扉を閉めた状態であっても庫内灯は消灯せず、庫内灯付近の温度が上昇し庫内の食品温度に影響を与えるという問題点があった。
【0005】
この発明は、上記のような問題を解決する為になされたもので、扉開閉によりON/OFFするスイッチが故障した際にも、冷蔵庫の電源をOFFした状態のままにしなくても庫内の食品温度に影響を与えること無く制御を行える冷蔵庫の制御装置を得ることを目的とする。
【0007】
【課題を解決するための手段】
請求項1の冷蔵庫の制御装置は、扉の開閉によりオン/オフする扉開閉スイッチと、扉の閉め忘れを知らせるためのアラームとを有する冷蔵庫において、電源投入時前記扉開閉スイッチがオフの場合は電源オン時扉開(F)をセットする手段と、扉開閉スイッチのオフを検出してから所定時間経過し、電源オン時扉開(F)がセットされている場合はアラームをオフする手段と、扉開閉スイッチがオンの場合は、電源オン時扉開(F)及び扉開タイマーをリセットし、次回扉が開けられた場合には、所定時間後はアラームをオンする手段とを備え、電源オン時扉開(F)及び扉開タイマーがリセットされた状態で、扉開閉スイッチのオフを検出してから所定時間経過し、扉が閉まっているにも拘らずアラームが所定時間オンする場合は、冷蔵庫の電源再投入時に、電源オン時扉開(F)をセットする手段、アラームをオフする手段、及び、所定時間後はアラームをオンする手段により、アラームをオフすることを特徴とする。
【0009】
【発明の実施の形態】
実施の形態1.
以下、この発明の実施の形態1を図について説明する。
図1は、この発明の実施の形態1による冷蔵庫の全体構成図である。図において、1は扉の開閉によりON/OFFするスイッチ(扉開閉スイッチ)、2は扉閉め忘れを知らせるアラーム、3は庫内を照らす庫内灯、4は冷蔵庫全体を制御する制御基板である。
【0010】
次に動作を説明する。図2はこの発明の実施の形態2による冷蔵庫の制御装置の制御のフローチャート図である。まずステップ10で扉開閉スイッチ1の状態を判定し、OFF開信号の場合には、ステップ11で扉開閉スイッチ1OFFの時間が10分以内かどうかを判断し、10分以内の場合には1分毎にアラームを2開ずつ鳴らし、5分以降は連続して鳴らす(ステップ12)。また扉開閉スイッチOFF10分経過後は、アラームをOFFし(ステップ14)、扉開閉スイッチON閉信号の場合は扉開時間をカウントする10分タイマーはリセットし(ステップ13)、次回扉が開けられた場合(扉開閉スイッチ1がOFF)には、同様にアラーム処理を行う。
【0011】
この実施の形態1の冷蔵庫の制御装置は、扉開閉によりON/OFFするスイッチ(扉開閉スイッチ)が途中故障した場合、従来は扉を閉めた状態であっても扉閉め忘れを知らせるアラームは鳴り続け、アラームを止める為には冷蔵庫の電源をOFFする方法しかなかったが、その場合でも扉をそのまま閉めておくだけで、アラームは自動的に停止する為、庫内の食品温度に影響を与えず、またユーザーに音的にも迷惑を掛けることがなくなる。
【0012】
実施の形態2.
以下、この発明の実施の形態2を図について説明する。図3、図4はこの発明の実施の形態2による冷蔵庫の制御装置のフローチャート図である。図3は電源を入れた際の処理で、ステップ20で電源を入れた際に、ステップ21で扉開閉スイッチ1の状態を判定し、扉開閉スイッチ1がOFF開信号の場合には電源ON時扉開(F)をセットする(ステップ22)。図4は扉開閉によるアラームのON/OFF処理である。電源投入時より扉信号が開いたままの入力であれば、5分以降は、電源ON時扉開(F)が1であるため(ステップ33)、5分以降はアラームは止まる(ステップ36)。また扉開閉スイッチON閉信号の場合には電源ON時扉開(F)、扉開5分タイマーをリセットするため(ステップ32)、次回扉が開けられた場合には、5分以降は連続してアラームを鳴らす(ステップ35)。5分以降連続してアラームが鳴る場合は、ステップ37で扉状態を見て、閉状態であれば扉開閉スイッチ1が故障しているので電源再投入することにより、ステップ30→ステップ31→ステップ33→ステップ36のフローによりアラームは止まる。
【0013】
この実施の形態2の冷蔵庫の制御装置は、扉開閉によりON/OFFするスイッチが途中故障した場合、扉を閉めた状態であっても電源を入れ直せば、アラームは自動的に停止する為、庫内の食品温度に影響を与えず、またユーザーに音的にも迷惑を掛けることがなくなる。
【0014】
実施の形態3.
以下、この発明の実施の形態3を図について説明する。図5はこの発明の実施の形態3による冷蔵庫の制御装置のフローチャート図である。
次に図5を用いて請求項3の動作を説明する。まずステップ40で扉開閉スイッチ1の状態を判定し、OFF開信号の場合には、ステップ41で扉開閉スイッチ1OFFの時間が10分以内かどうかを判断し、10分以内の場合には庫内灯を点灯させる(ステップ42)。また扉開閉スイッチOFF10分経過後は、庫内灯をOFFし(ステップ44)、扉開閉スイッチON閉信号の場合は扉開時間をカウントする10分タイマーはリセットし(ステップ43)、次回扉が開けられた場合には(扉開閉スイッチ1がOFF)、同様に庫内灯処理を行う。
