Abstract (en)
[origin: EP1367335A1] Ventilation device that channels air into a spiral, thereby facilitating its extraction, for which it is provided with a spherical base (3), a spherical deflector (2), and a cylindrical body (3). The deflector (2) and the base (3) are spherical and are made from galvanised or stainless steel plate in a single piece, and do not have any orifices. In addition the cylindrical body (1) is provided internally with the motorised fan (7), beneath which is placed the motor case (12), and is also provided with the motorised window (5) that has a wavelike shape. The supports (8) for the motorised fan (7) and the supports (6) of the deflector (2) have a special design.
