VENTILATION DEVICE

摘要

A ventilator is provided to use one connection duct arranged at the air supply and discharge paths to work as the suction and discharge ducts and to improve the installation efficiency by finishing the duct installation with one connection duct. A ventilator comprises a body(10) mounted at the inside to form the external appearance; and a connection duct(50) installed by penetrating a wall surface(W) to connect the body and the outdoor space, wherein the air is flowed by penetrating the wall surface of the building. The inside of the connection duct has a suction path(51a) guiding the outdoor air sucked from the outdoor space to the body and a discharge path(51b) guiding the indoor air sucked from the indoor space to the outdoor space. The body is installed at the corner of the indoor space, wherein the center angle of the end of the rear end side is practically formed with 90‹ and first and second communicating holes(14a,14b) are connected with the connection duct at both side surfaces forming the corner part of the rear end of the body. The connection duct is installed with a duct unit(51) connected to one of the first and second communication holes and a cover unit(52) extended from one side of the duct unit to cover the other of the first and second communication holes.
