Abstract: A cooking pan provided with an exhaust device is capable of reducing smells or smoke generated when food is cooked. The cooking pan includes a distribution plate that is installed at the center of a lower surface of a bottom part of the cooking pan with a predetermined gap to form an exhaust space part, and an exhaust pipe that connects the exhaust space part with an interior of the cooking pan. Thus, the smells and smoke of the interior of the cooking pan are forcibly discharged and burnt by a pressure difference between the interior and exterior of the cooking pan and by flowing flames applied to the distribution plate of the lower surface of the cooking pan, so that the unpleasant smells and smoke are remarkably reduced, as is the emission of carbon dioxide.
