PROBLEM TO BE SOLVED: To provide a warm storage device where temperature distribution in a warm storage chamber can be homogenized. SOLUTION: On the rear surface of a heater panel 6, reinforcing members 8 for preventing curving are provided in spaces between three areas in which cord heaters 7 are arranged, respectively. Each reinforcing member 8 is obtained by curving and forming a pair of partition pieces 82 with a spacing on both side edges of a virtually long plate face 81. The plate face 81 is fixed to the panel 6 and the partition pieces 82 are fitted to the inner wall of a main body. Three ducts 62 to 64 are formed side by side, and the spaces between the partition pieces 82 of the reinforcing members 8 function as a communication part 9 between adjacent ducts. With driving of a fan F, warm air is blown and flows downward to each duct 62 to 64 to make a circulation current of blowing out from a lower end and rising within the warm storage chamber. Warm air blown into each duct 62 to 64 in this case flows properly to an adjacent duct through the communication part 9 and simultaneously flows down smoothly without stopping in the middle. Thus, the temperature of the heater panel 6 is kept to be uniform through the whole surface. COPYRIGHT: (C)2004,JPO
