摘要:
A small and lightweight sound-proof generator exhibiting sufficient cooling effect. An inverter (19), an engine fan (32), a power generating body (33), an engine (34), a recoil fan (61), a recoil starter (63) are coaxially arranged sequentially from a first inlet port side. A first cooling air passage for cooling inverter (19), the power generating body (33), and the engine (34) with cooling air sucked by the engine fan (32) from the inlet port (21), and second and third cooling air passage for cooling a space surrounded by an inverter containing box (20), an engine fan cover (31), an engine cover (36) and a muffler cover (52) and a soundproof case with cooling air sucked by the recoil fan (61) from inlet ports (21b1) and (21b2) are formed. Cooling air passed through the first cooling air passage and cooling air passed through the second and the third cooling air passages are merged and discharged from an outlet port after cooling a muffler.
