An electric range is provided that may include a case, a cover plate coupled to an upper end of the case and having an upper surface on which a heating target is disposed, and an air guide forming a flow path of air, wherein the air guide includes a element installation portion which is disposed in a portion of the air guide.

A home appliance is provided that may include a first air flow path included in a heat sink, and a second air flow path defined at a lower side of the heat sink, such that air flows to inside and outside of the heat sink efficiently. A plurality of heat dissipation fins may protrude downward from a wall of the second air flow path, increasing a contact surface between the heat sink and air. A projection may be formed on at least one of the walls of the first air flow path, the walls of the second air flow path, an outer surface of the plurality of heat dissipation fins, or an upper surface of the heat sink.

An electric range is provided that may include a case, a case, a cover plate coupled to an upper end of the case, wherein an object to be heated is placed on an upper surface thereof, an air blowing fan configured to discharge air, and an air guide that communicates with the air blowing fan, wherein a cross-sectional area of the flow path of air in a portion of the air guide at which air is discharged outward is greater than a cross-sectional area of the flow path of air at a portion of the air guide at which the air guide and the air blowing fan communicate.

An electric range is provided that may include a case that defines an external appearance of the electric range; at least one heater that heats an object; at least one upper bracket that is disposed under the at least one heater to support the at least one heater; and a support disposed under the at least one upper bracket. The support may include a mount on which a printed circuit board is mounted, and a boss portion that supports the at least one upper bracket.

An electric range is provided that may include a dedicated coil temperature sensor configured to measure a temperature of a working coil so as to monitor the temperature of the working coil in real time and actively respond to a working coil load condition, thereby remarkably increasing an operation time of the electric range.

An electric range is provided, in which a portion of a bracket, which is configured to support at least one heating unit, is bent downward. More specifically, the at least one heating unit may be mounted in a specific region on the bracket, and a recessed portion which is downwardly formed may be formed in a portion of the specific region. Accordingly, an electric wire disposed between the at least one heating unit and the bracket may be accommodated or disposed in the recessed portion, so that interference between the electric wire disposed between the at least one heating unit and the bracket and the at least one heating unit may be prevented.
