  • the inlet port 121 has a grease filter 121a for filtering greasy vapor generated during cooking foods.
  • the indoor air inlet 124 is preferably positioned in the middle of an upper surface of the horizontal exhaust duct 120 in order to uniformly blow the indoor air sucked by the suction fan 130 through the nozzles 123.
  • the indoor air is blown through the nozzles 123 formed at the outer periphery of the lower surface of the horizontal exhaust duct 120 with high pressure.
  • the blown indoor air serves as an air curtain.
  • a collection zone for collecting the contaminated gas is formed at a bottom of the horizontal exhaust duct 120.
  • the collection zone 129 refers to an imaginary space of a square shape formed with the wall surface 11a and three sides of outer periphery of the horizontal exhaust duct 120 at which the nozzles 123 are formed.
  • An unexplained reference numeral 30 indicates a gas range, 31 indicates a burner portion, 32 indicates a food container and 11a indicates an inner wall of the kitchen.
  • the suction fan 130 installed in the horizontal exhaust duct 120 is operated.
  • the indoor air is thereby flowed in the passage 125 through the indoor air inlet 124, and the indoor air flowed in the passage 125 is led to each nozzle 123 by the guider 127.
  • each nozzle 123 serves as an air curtain, being emitted with high pressure through the nozzles 123. At this time, the contaminated gas generated during cooking foods does not spread over the whole room but is collected in the collection zone 129 formed at the bottom of the horizontal exhaust duct 120.
  • the exhaust fan 111 is operated to suck the contaminated gas through the inlet port 121.
  • the sucked contaminated gas is discharged to the outside of the room through the vertical exhaust duct 110.
  • the greasy filter 121a performs a function of filtering greasy vapor contained in the contaminated gas passing through the inlet port 121.
