<P>PROBLEM TO BE SOLVED: To achieve efficiently heating of a heating body to be heated for preventing heat transferring efficiency from being significantly damaged by circulating hot air inside a heating chamber or circulating to a blower fan or heater so as to improve speed of preheating or cooking in the heating chamber. <P>SOLUTION: There is provided a heating device, including a heating chamber 13 in which a heating body to be heated 12 can be placed, a blower fan 25 which is adjacent to the heating chamber 13 and circulates heat from a heat source, and a rear wall 19 by which the heat chamber 13 and a heat source chamber 23 are divided and a suction port 26 and blow-out ports (upper blow-out ports 27, middle blow-out ports 28, lower blow-out ports 29) are provided. In the device, a heater 24 provided on the periphery of the blower fan 25 and flow passage plates 31, 32 provided on the periphery of the heater 24 for dividing flow passages are disposed so that hot air from the blow-out ports (upper blow-out ports 27, middle blow-out ports 28, lower blow-out ports 29) is optimally allocated in the heating chamber 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
