Abstract

An exhaust hood is disclosed. The exhaust hood includes: a hood body (110) including a canopy (111) provided with an inlet (123) and an exhaust part (141) communicating with the canopy (111) and provided with an exhaust path (143); and a nozzle unit (210) installed in front of the hood body (110) and including a first nozzle (211) through which the air is discharged, a first curved shape portion (213) having an arc shaped section which is convex outwardly and formed to allow the air discharged from the first nozzle (211) to flow along its outer circumferential surface, and a second curved shape portion (217) spaced apart from an inner circumferential surface of the first curved shape portion (213) at a constant interval and having a diameter smaller than that of the first curved shape portion (213), and a second nozzle (215) formed between the first curved shape portion (213) and the second curved shape portion (217), through which the air is discharged.
By the exhaust hood, the polluted air flowing to the front of the exhaust hood can be effectively introduced to the inlet and be collected. Accordingly, pleasant kitchen and laboratory environments can be formed.
