Abstract: An induction heating device includes a casing; a first induction heating module in the casing; a first heat sink located below the first induction heating module; a first heat pipe that passes through the first heat sink, that extends outward from the first induction heating module, and that is configured to discharge heat from the first heat sink out of the first induction heating module; an air-discharge fan located at an inner side of the casing and configured to discharge air from inside of the casing to outside of the casing; and a cooling fan located at the inner side of the casing and configured to blow air to the air-discharge fan. The first heat pipe has an end that protrudes from the first induction heating module and that is located at an air-flow path defined between the cooling fan and the air-discharge fan.

Abstract: A steam generator and a cooking device including the same, according to an embodiment of the present invention may include a water supply pipe into which steam water is introduced, a heating chamber having a chamber body and a chamber cover, and a steam heater configured to provide heat, wherein the steam heater is provided to be embedded in the chamber body and the chamber body includes a plurality of partition walls protruding in one direction along an inner peripheral surface to form a Z-shaped steam flow path through which supply water introduced into the chamber body and steam generated by heating the supply water flow. Therefore, the heat transfer, which had been concentrated only in a predetermined region, may be dispersed by the flow path formed in the chamber body, thereby stably generating the steam even in repetitive steam generation operation.
