ン発電機の排気ダクト構造。 The soundproof case that houses the engine and the generator driven by the engine is made of a steel plate with sound absorbing material attached to it, and outside air is taken into the soundproof case through the intake port, and a muffler is housed in the hot air inside the soundproof case. In the exhaust duct structure of a soundproof engine generator having a radiator fan for discharging the air from the exhaust port to the outside through the exhaust duct, the upper part of the exhaust duct slopes diagonally upward and the lower part hangs downward. It is vertically divided into two chambers by a first partition plate, and the first chamber of the exhaust duct faces the exhaust port of the radiator and houses the muffler, and the first chamber and the second chamber of the exhaust duct are separated. are communicated through vents on both sides of the upper part of the first partition plate, an exhaust port is provided in the soundproof case above the first partition plate with a baffle plate interposed therebetween, and a baffle plate is provided in the upper part of the exhaust duct. A ventilation hole in the center of the resistance plate located in front of the resistance plate and a second partition plate arranged at a distance from the resistance plate on both sides of the ventilation hole and located at a position that does not overlap with the ventilation hole of the resistance plate. An exhaust duct structure for a soundproof engine generator, characterized in that the exhaust duct is communicated with a soundproof duct through an opening vent, and an exhaust port is formed in a soundproof case at the end of a flow path of the soundproof duct.
