Abstract

An exhaust device (1) having deflection plates (3,4) comprises a cabinet (2) that is provided with a space (27) therein. An opening is formed in front of the cabinet. The air-extraction hood (21) located at the top of the cabinet is provided at the bottom thereof with an elongate air-extraction slot (212) facing downwards and parallel to a rear plate (26). A left deflection plate (3) is vertically located in the space in a manner of being relatively oblique to a left lateral plate (23) while a right deflection plate (4) is vertically located in the space in a manner of being relatively oblique to a right lateral plate (24). Thereby, the air drawn towards the elongate air-extraction slot can flow into the cabinet via the left and the right deflection plates so as to prevent the leakage of pollutants from the opening in front of the cabinet.
