EXHAUST HOOD

摘要

An exhaust hood is provided to restrain contaminated air from being diffused into the interior of a room by using a front surface collection section. An exhaust hood includes a hood body(110) and a front surface collection section(210). The hood body includes a canopy(111) and an exhaust section(141). A suction section is formed on the bottom surface of the canopy so as to suck air. The discharge section discharges the air sucked through the suction section to the outside. The hood body is horizontally disposed on the upper side of the contamination air discharge region. The air flowing along the inner surface of the first curved wall section is discharged through the second nozzle section. The front surface collection section includes a first nozzle section(211), a first curved wall section(213), and a second nozzle section(215). The front surface collection section collects the air in the front region of the canopy to flow the air toward the suction section.
