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.
Claims19
An electric range, comprising:
- 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;
- an air guide that communicates with the air blowing fan, and forms a flow path of air;
- a base bracket allowing a printed circuit board to be mounted thereon;
- and
- a heat sink being mounted onto the printed circuit board, wherein the heat sink is provided with a flow channel that passes through the heat sink in a lengthwise direction of the heat sink and forms a flow path of air.
4 more elements
An electric range, comprising:
- 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 that is 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;
- 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, wherein a cross section of the air guide expands in a lengthwise direction of the air guide or in a direction perpendicular to the lengthwise direction of the air guide, and wherein the air guide includes a first coupling projection that protrudes from the air guide at an end opposite the air blowing fan and is coupled to the base bracket, and wherein the heat sink is provided with a flow channel that passes through the heat sink in a lengthwise direction of the heat sink and forms a flow path of air.

- 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 that is 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;
- 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, wherein 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;
- a second air guide that communicates with the first air guide, is bent in an upward-downward direction of the base bracket, and guides air such that the air is discharged in a vertical direction;
- a third air guide that extends from the first air guide is bent from an end portion of the first air guide to change a flow direction of air having passed through the first air guide, wherein side walls of the third air guide are slanted with respect to a lengthwise direction of the air guide;
- and
- a fourth air guide that extends from the third air guide and is bent from an end portion of the third air guide, wherein a cross section of the air guide expands in the lengthwise direction of the air guide or in a direction perpendicular to the lengthwise direction of the air guide, wherein the air guide includes a first coupling projection that protrudes from the air guide at an end opposite the air blowing fan and is coupled to the base bracket, and wherein the heat sink is provided with a flow channel that passes through the heat sink in a lengthwise direction of the heat sink and forms a flow path of air.
