PURPOSE:To perform an economical heating of a pan, by a method wherein an iron box is placed on another iron box, the insides of the two boxes are formed in a waveform, a nichrome plate is housed in a space between the two boxes, and air heated by energization is introduced into a portable cooking stove. CONSTITUTION:A recess, whose bottom is formed in a waveform, is formed in an upper surface of a cubical iron box, and meanwhile, a recess, in which a down bottom surface formed in a waveform matching the bottom in a waveform of the former recess is provided, ia formed in an undersurface of a box 4 serving as a like iron cover. A nichrome plate 1 is housed in a space part provided when the cover 4 are placed over the box 3, and a fan 5 is installed to a spreading end, being open to the outside, of the space part. Hot blast is generated by heating of the nichrome plate 1 through energization of it, and the hot blast is blowed to a portable cooking stove 7 with the fan 5 operated to perform a heating of a pan placed on the portable cooking stove 7 with a jet of it through jet nozzles 6. |
