PURPOSE:To enable a combustion air supply fan, an exhaust fan and a convection fan to be rotated by flame by using a hot gas reciprocating engine. CONSTITUTION:After fuel ignition, when a heated part 31 of a hot gas reciprocating engine 5 has been heated sufficiently, a temperature difference is created between the heating space 31 and cooling space 32 so that the working gas in both spaces may repeat a closed cycle including isothermal compression, isochoric heating, isothermal expansion and isochoric cooling. Consequently, a displacer 33 and a piston 34 reciprocate in a cylinder 39 with a phase difference, and the reciprocating motion can be converted by a crank mechanism 38 into a rotary motion so that crank shafts 6, 6' and 6'' may rotate by themselves without any assistance of a starting motor 26. By this arrangement, a combustion air supply fan 7 and an exhaust fan 8 can continuously rotate without consuming a battery 27 thereby enabling stable combustion to be achieved. |
