PROBLEM TO BE SOLVED: To perform a fast decreasing in temperature at a prescribed object part in a device upon termination of a reheating mode.SOLUTION: This invention relates to a cool temperature storage device to enable both a refrigeration mode in which a cooling part 33 is operated at both heat exchanging chambers 31, 32 and cold air is circulated and supplied to both a heat storage chamber 25H and a cold storage chamber 25C to cause both warm foods and cold foods on a tray X to be refrigerated and reserved, and a re-heating mode in which an operation is changed over from a cooling part 33 to a heating part 34 in the first heat exchanging chamber 31 and in turn the cooling part 33 is subsequently operated in the second heat exchanging chamber 32, heat air is circulated in the heat storage chamber 25H to cause the warm foods to be reheated and in turn the cold foods is subsequently refrigerated and reserved in the refrigeration chamber 25C. There is provided temperature lowering means 50 for decreasing a temperature of a prescribed object 25H in the device upon termination of the re-heating mode.【課題】再加熱モードの終了時に装置における所定の対象部を速やかに降温する。【解決手段】両熱交換室31,32で共に冷却部33が作動され、温蔵室25Hと冷蔵室25Cとに共に冷気が循環供給されることで、トレイX上の温食と冷食とが共に冷蔵保存される冷蔵モードと、第1熱交換室31において冷却部33から加熱部34の作動に切り替わる一方、第2熱交換室32では引き続き冷却部33が作動状態とされ、温蔵室25H内には暖気が循環されることで温食が再加熱される一方、冷蔵室25C側では冷食が引き続き冷蔵保存される再加熱モードと、が実行可能な冷温蔵装置であって、再加熱モードの終了時に当該装置における所定の対象部25Hの温度を下げる降温手段50が設けられている。【選択図】図4
