PROBLEM TO BE SOLVED: To uniformly and smoothly warm all housed hot packs P, and to suppress temperature rise on the outer surface of a sidewall 11.SOLUTION: The inside of a warming container 1 made of a heat insulation box is sectioned into multiple sections by a partition member 5, heaters 9a, 9b and 9c are arranged on both sidewalls and a bottom wall of the warming container 1 and the partition member 5, and the hot packs P are housed inside the container. When the hot packs are mounted on the partition member, the housing amount of the hot packs is increased, and they are easily taken in and out. The output of the respective heaters is increased in the order of the partition member heater 9c, the bottom wall heater 9b and the sidewall heater 9a to uniformly warm the inside of the container and save energy. Hot air (a) rises from the inside of the container at the lower part to the inside of the container at the upper part through a gap t between the inner surface of a door 2 and the front surface of the partition member, and the inside of the container is uniformly and smoothly warmed and energy is saved. The sidewall 11 is cooled by distribution of air (a) from the lower end opening 15 to the upper end opening 17 of the inner side ventilation path 14, and the temperature rise on the sidewall outer surface is suppressed.COPYRIGHT: (C)2013,JPO&INPIT【課題】収容したホットパックPの全てを均一かつ円滑に加温し、かつ側壁11外面の温度上昇を抑える。【解決手段】断熱箱製加温庫1内を仕切り部材5によって複数に区画し、その加温庫1の両側壁、底壁及び仕切り部材5にヒータ9a、9b、9cを配置し、庫内にホットパックPを収容する。仕切り部材上にホットパックを載置すれば、ホットパックの収容量を増すことができるとともに、取り入れ・取り出し易い。各ヒータの出力を、仕切り部材ヒータ9c、底壁ヒータ9b、側壁ヒータ9aの順に大きくして、庫内の加温を均一かつ省エネする。扉2の内面と仕切り部材前面との間隙tを介し下方の庫内から上方の庫内に熱気aが上昇して、庫内を均一かつ円滑に加温かつ省エネする。側壁11は、その内側通気路14の下端開口15から上端開口17に空気a’が流通して冷却され、その側壁外面の温度上昇が抑制される。【選択図】 図7
