Abstract: An electric range is provided that may include a case, a cover plate coupled to an upper side of the case, and on which an object to be heated is placed, an air blowing fan discharging air, and an air guide that communicates with the air blowing fan, and forms a flow path of air. The air guide comprises a first air guide that communicates with the air blowing fan and guides the air discharged from the air blow fan substantially horizontally, and an expansion protrusion that protrudes from the first air guide in a lengthwise direction of the air guide or in a direction perpendicular to the lengthwise direction of the air guide such that a cross section of the air guide expands.

Abstract: An electric range includes a heating part configured to heat an object based on an electromagnetic interaction. The heating part may include a core frame having a plurality of channels disposed radially on a lower surface thereof and a plurality of ferrite cores mounted onto the channels and disposed under the core frame. The core frame include a plurality of air gaps disposed between the plurality of channels. The plurality of air gaps are disposed radially, and the plurality of air gaps connect a center of the core frame and an edge of the core frame.
