Claims

[Scope of utility model registration request]

A soundproof box that houses a vacuum generator therein and includes a gas flow path that circulates cooling gas inside and outside the box, and a blower fan that forcibly circulates the cooling gas through the gas flow path. At least part of the wall surrounding the soundproof box has a double structure with a cavity inside, and the vacuum generator of the soundproof box is housed through the cavity inside the double structure wall. A gas discharge passage forming a part of the above-mentioned gas flow passage is provided to discharge the gas in the internal space to the outside of the soundproof box. Located inside the cavity inside the double-walled wall of the soundproof box that constitutes the above gas discharge path,
A soundproof box characterized by having an outlet for gas discharged from a vacuum generator housed inside the soundproof box.
