Abstract

PURPOSE:To prevent the increase of the temperature of an outer case to a high value by a method wherein a cold air intake hole and a hot air discharge hole are formed in a heat shielding cylinder to shield the heat of a heat transferring cylinder and that of the outer case. CONSTITUTION:High temperature gas generated by combustion is exhausted through an upper opening part 4 of a burning cylinder 3, and the high temperature gas is mixed in side an air duct 8 with cold air taken in with the aid of a blast fan 6 to produce hot air, which is guided to a hot air discharge port 7. Meanwhile, high temperature gas is taken through an end opening (a) to the interior of a heat transferring cylinder 11 to heat a substance 17 to be heated placed on the upper part of an end (b) of the cylinder 11. In this case, cold air is taken in through a cold air intake hole 15a with the aid of the fan 6, and is discharged through a hot air discharge hole 15b after flowing through a space between the cylinder 11 and a heat shielding cylinder 12. Since heat shield of the surroundings of the cylinder 11 is effected by means of the cold air, an outer case 5 is prevented from being heated uselessly.
