を特徴とする排気用フード。 It has a front wall, a ceiling wall, a back wall and both side walls,
and a hood casing having an opening extending in the width direction on the front wall, and an air jet duct provided at the inner lower part of the rear wall of the hood casing, and a nozzle on the upper surface of the air jet duct over the entire length in the width direction. an air ejection means for pressurizing air into the air ejection duct and ejecting the air upward from the nozzle; and an air inlet formed on the inside of the ceiling wall of the hood casing with an intake port facing in the width direction. an exhaust duct is arranged, and the air inside the hood casing is sucked into the exhaust duct from the intake port,
an exhaust means for discharging the air to the outside; the air jetting means and the exhaust means generate a swirling flow within the hood casing, and the swirling flow causes outside air to be drawn in from the opening. In this exhaust hood, the outside air is discharged to the outside in a swirling flow, and a terminal box of the air blowing means is disposed approximately at the center of the inner upper part of the rear wall of the hood casing, and the terminal box is disposed within the terminal box. An exhaust hood comprising an air supply duct that accommodates a blower and communicates downward from the terminal box to approximately the center of the air jet duct.
