Claims

[Scope of utility model registration request]

An engine installed on a base and a generator driven by the engine and equipped with a cooling fan equipped with a cooling air intake and a cooling air outlet are surrounded by a soundproof case, and outside air is introduced into the soundproof case. In addition, in the cooling structure of a soundproof engine generator equipped with a radiator fan for discharging hot air after cooling, an exhaust duct is provided inside the soundproof case by a partition wall,
The engine and generator are housed in separate rooms, and when configuring the generator, only the cooling air outlet faces the room on the engine side, and an intake duct is installed in the room where the generator is housed. The room where the generator is housed and the room where the engine is housed are communicated with each other through a ventilation duct provided inside the roof panel, and the room where the engine is housed is provided with the above-mentioned exhaust gas. A cooling structure for a soundproof engine generator characterized by communication with the outside through a duct.
