PROBLEM TO BE SOLVED: To solve the problems that conventional thawing means has a considerably large drip amount because the cells of a frozen food are disrupted in thawing the food, leading to such phenomena as to impair the freshness, taste, or the like of the food, discolor the food and tend to breed sundry germs, thus resulting in impairing the texture and appearance of the food and cutting the foods relishing period besides, there have not been provided retractable frozen food-thawing chambers so far.SOLUTION: A retractable frozen food-thawing chamber utilizing far-infrared rays and negative ions is configured such that: top plates are furnished on top of the chamber body of thermal insulation construction and a device unit, respectively a drawer is furnished retractably via an opening in the front side of the chamber into/out of the chamber the rear surface and the left and right surfaces in the chamber are furnished with negative ion-generating surfaces doubling as far-infrared rays-radiating surfaces, respectively, wherein the negative ion-generating surface doubling as the far-infrared rays-radiating surface on the rear surface is furnished with a heating sheet the chamber includes: a fan a humidifier and the jet port of a mist generator the device unit includes: a refrigerating machine the mist generator and an operating panel as to the drawer, the front face plate is of thermal insulation construction the left and right side plates are metallic perforated ones the rear face is a resin plate via which far-infrared rays are transmitted and the bottom surface of the chamber is detachably furnished with a ventilative and water-penetrable plate.COPYRIGHT: (C)2011,JPO&INPIT【課題】従来の解凍手段は解凍時に冷凍食品の細胞が破壊されるためドリップの量が極めて多く鮮度、味等が損なわれ、変色が生じ雑菌が繁殖し易くなるなど食品の食感、外観を損ない賞味期間を短縮する課題があり、また、引出し式の冷凍食品解凍庫はこれまで提供されていない課題があった。【解決手段】断熱構成の庫体と機器部の上面に天板を備え、引出しを前面開口から庫内に出入自在に備え、庫内の後面、左右面にマイナスイオン発生兼遠赤外線放射面を備え、後面のマイナスイオン発生兼遠赤外線放射面に加熱シートを備え、庫内に送風機、加湿器、ミスト発生器の噴気口を備え、機器部に冷凍機、ミスト発生器、操作盤を備え、引出しは
