とができることとなる。In the above structure, the exhaust gas and oil smoke generated from the cooking utensil rise as they rise, and the hood body 1
Diffuses over the entire lower surface opening. Then, when the motor 7 is operated, most of the central portion of the exhaust gas and oil smoke diffused over the entire lower surface opening of the hood body 1 passes through the orifice-shaped ventilation hole 9 of the lower surface cover 11 and the lower surface suction port 3 of the casing. It is discharged to the outside through the blade 8 and the adapter 5 duct 6. Further, the exhaust gas and oil smoke diffused near the end of the lower surface opening of the hood body 1 are sucked into the hood body 1 through the gap 10 between the lower surface opening of the hood body 1 and the lower surface cover 11 and the upper surface suction port of the casing 4. From 2, it passes through the blade 8 and is discharged to the outside through the adapter 5 duct 6. In other words, it is generated from the cooking utensils and rises while spreading.
Most of the oil smoke and exhaust gas are discharged to the outside from the orifice 9 of the lower surface cover 11, and the oil smoke and exhaust gas diffused to the outer peripheral portion are sucked from the gap 10 in the outer peripheral portion of the lower surface opening of the hood body 1, Since the air is discharged through the casing 4 to the outside, the exhaust gas and oil smoke diffused to the lower surface of the hood body 1 can be reliably collected with a small amount of air and discharged to the outside.
