An induction ventilation system for air supply and exhaust, comprising:

• an upper plate that has an induction heating portion that heats a cooking vessel based on electromagnetic induction, on an upper surface thereof, is unified with an upper portion of a first storage portion within a sink table, and has a lift hole communicating with the first storage hole, in a rear portion thereof;
• a vertically movable unit that is installed in a position corresponding to the lift hole of the upper plate, is moved up and down by a lift means installed in the first storage portion, and includes a filter provided in an air suction passage;
• an air suction and discharge unit including a chamber that is installed in a lower rear portion of the first storage portion and is provided with an oil drain hole at a lower end thereof, a flexible duct connected between the vertically movable unit and the chamber, an air suction fan that is installed in the chamber and draws indoor air through the air suction passage, and a discharge pipe that is connected to the chamber and through which indoor air drawn by the air suction fan is discharged outside a room;
• a grease tray that is installed under the chamber to collect grease that condenses on surfaces of the air suction passage, the filter, the flexible duct, and the chamber and flows down through the grease drain hole;
• an air supply hood that is installed above the upper plate and guides the indoor air to the air suction passage in the vertically removable unit by supplying air to the upper plate using an air supply fan;
• and
• a second storage portion unified with an upper portion of the air supply hood,
• wherein the lift hole in the upper plate is provided with a support protrusion and an anti-contamination member that comes into tight contact with a surface of the vertically movable unit is supported on the support protrusion.
