EXHAUST GRILLE Russian patent published in 2015 - IPC A47L9/00

Abstract RU 2563787 C1

FIELD: ventilation.

SUBSTANCE: exhaust grid is implemented in the form of a structure containing a grid of deflectors (15) located with intervals which form a set of separate nonlinear air flow channels through the grid. The grid is designed so that to deflect the sound waves falling on the grid for prevention of their passing through channels. Various configurations of the exhaust grid are described.

EFFECT: exhaust grid configuration reduces levels of noise, capable to pass through the grid.
