PURPOSE:To prevent contamination of wall surfaces in a hood, a ventilation fan, and the periphery of an exhaust port due to oil components by providing a foam generating device and a foam transfer device for transferring foam in an interior hood to cause the oil components of oil mist to be selectively adsorbed on foam and removed without lowering ventilation efficiencies for discharging air and smoke. CONSTITUTION:A foam discharging device and a foam transfer device for transferring foam are provided in an interior hood 1. Further, a foam breaking device 7 having thereon a plurality of upstanding pins 6 is disposed in a hood 5 on the exterior side of a ventilation fan 4. As a result, oil components in oil mist can be removed efficiently and contamination due to oil of the interior of the hood 1, the fan 4, and the periphery of an exhaust port can be prevented. Further, by efficiently breaking the foam, the oil components can be removed to be abandoned and foaming and cleaning agents can be reused. |
