<p>PROBLEM TO BE SOLVED: To provide a soundproof box which achieves both prevention of water entry and easiness of maintenance and inspection work.SOLUTION: An opening/closing door 16 is provided for opening/closing an inspection window 17 formed on an upper surface, and an air exhaust port 21 for exhausting air inside a soundproof box 1 is formed at the opening/closing door 16. An exhaust air duct 30 which has a box shape in which side walls 32-35 are erected from four sides of a bottom plate 31 and in which a drain hole 37 is formed at one side 31a of the bottom plate 31 partitioned by a partition wall 36 and a ventilation port 38 is formed at the other side 31b is installed on a rear surface of the opening/closing door 16. A lower part of the air exhaust port 21 is covered by the one side 31a of the bottom plate 31, and a drain passage 50 for discharging rainwater to the outside of the machine is arranged at a lower part of the drain hole 37, so that the rainwater passing through the air exhaust port 21 is discharged to the outside of the machine via the drain hole 37 and the drain passage 50. Thereby, entry of water into the soundproof box 1 is prevented, and maintenance and inspection work via the inspection window 17 can be performed only by opening the opening/closing door 16 without attaching/detaching the air exhaust air duct 30.</p> |
