Abstract: Provided is a cooking top including a main body including a heating unit, and an air curtain device that generates an air curtain flow that blocks diffusion of air flow generated by the heating unit. The air curtain device may include an intake port formed at the main body, an exhaust port that extends laterally along an upper portion of the main body, a flow guide that extends from the intake port to the exhaust port, a drive unit installed inside the flow guide to generate airflow, and an airflow control device rotatably mounted at the main body to open and close the exhaust port and configured to operate the drive unit when the airflow control device is rotated to open the exhaust port so as to generate the air curtain flow.
