PROBLEM TO BE SOLVED: To improve ventilation performance while reducing power consumption and reducing noise.SOLUTION: A ventilation system 1 including automatic ventilation operation execution means for actuating a ventilation fan 31 in accordance with an operation of igniting a burner 21, comprises: atmospheric state detection means 36, 37 detecting an atmospheric state above a gas cooking stove 2; ventilation determination means 304 determining whether the atmospheric state is a state requiring ventilation; and time measuring means measuring actuation time of the ventilation fan 31. An ignition-extinction interlocking control is executed to stop the ventilation fan 31 in accordance with an operation for extinguishing a fire of the burner 21 until first predetermined ventilation time S1 passes since the ventilation fan 31 is actuated by an automatic ventilation operation, and an atmosphere interlocking control is executed to stop the ventilation fan 31 if the atmospheric state is not the state requiring ventilation and to actuate the ventilation fan 31 if the atmospheric state requires ventilation after passage of the first predetermined ventilation time S1.SELECTED DRAWING: Figure 1 |
