Claims

[Scope of utility model registration request]

A generator G is connected to the rear of the engine E, and the engine E
A radiator 1 and a cooling fan 2 are placed in front of the radiator 1, the engine E and the generator G are entirely covered with a soundproof case 3, and cooling air is taken in from the air intake port 4 opened at the rear of the soundproof case 3. In a soundproof engine generator configured to cool a radiator 1 and then discharge the air to an exhaust port 5 opened in the front of a soundproof case 3, a centrifugal cooling fan 2 is installed in front of the engine E, and a radiator 1 is installed in front of the engine E. The centrifugal cooling fan 2 is surrounded by a spiral fan case 6, and a ventilation wall 7 is interposed between the radiator 1 and the engine E to partition a silencing chamber 8 and a ventilation chamber 9. An inlet 10 is opened in front of the fan case 6 to face the sound damping chamber 8, and an exhaust port 11 is opened in the circumferential direction of the cooling fan in the fan case 6 to communicate with the exhaust port 5 of the soundproof case, so that cooling air can be directed into the ventilation chamber 9. This soundproof engine generator is characterized in that the sound is introduced into a sound damping chamber 8 through a ventilation wall 7, further sucked into a fan case 6, and then discharged to the outside of the soundproof case through an exhaust port 11.
