A cooking appliance includes a body and a cooktop disposed on the body. A plurality of gas burner assemblies is operably coupled to the cooktop. A first frame member is coupled to a first side of the cooktop and defines at least a portion of a sump defined by the cooktop. A second frame member is coupled to a second side of the cooktop and defines at least a portion of the sump defined by the cooktop. A bracket is coupled to the first and second frame members. The bracket extends along a portion of a perimeter of the cooktop between the first and second frame members. The bracket defines at least a portion of the sump defined by the cooktop.

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, 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.

An electric range is provided that may include a case, and a support. The support may include a first region in which an air blower fan may be disposed, and a second region in which a printed circuit board may be disposed. A lower surface of the first region may be separated from the case.

A home appliance is provided in which electronic elements are attached to an outer surface of a heat sink, allowing air to directly contacting the electronic elements. More specifically, the electronic elements are attached to an outer slanted surface of the heat sink, an air guide is disposed to surround the heat sink to which the electronic elements are attached, and an air blowing fan is used to allow air to flow in the air guide, enabling the flowing air to directly contact the electronic elements.

An electric range may include a case, a cover plate coupled to an upper end of the case and on an upper surface of which an object to be heated is placed, a heat sink, an air blowing fan, wherein the air blowing fan is configured to discharge air toward the heat sink, and an air guide that communicates with the air blowing fan, surrounds the heat sink, and forms a flow path of air that cools the heat sink, wherein the air guide includes an side outlet formed in a portion at which the air guide communicates with the air blowing fan, and wherein the air guide is configured to discharge a portion of air flowing from the air blowing fan outward.

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, at least one heater that heats the object, the at least one heater being disposed under the cover plate, an upper bracket that is disposed under the at least one heater and supports the at least one heater, a base bracket disposed under the upper bracket and on which a printed circuit board is mounted, a heat sink mounted on the printed circuit board, an air blowing fan that is mounted on the base bracket and discharges air toward the heat sink through an outlet thereof, and an air guide that communicates with the air blowing fan, surrounds the heat sink, and forms a flow path of air cooling the heat sink.

A cooling system for a built-in induction hob with an improved cooling efficiency, and a cooling method thereof. The cooling system comprises an air blower for generating an airflow according to a first direction, a heat-sink device through which air blown by the air blower is conveyed. The cooling system further comprises airflow deflecting means for deflecting said airflow from said first direction to a second direction which significantly deviates from said first direction.
