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, 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.
Claims19
An electric range, comprising:
- a case;
- a cover plate coupled to an upper side of the case, on which an object to be heated is placed;
- an air blowing fan that discharges air;
- an air guide that communicates with the air blowing fan, and forms a flow path of air;
- and
- a vane that divides and guides a flow of the air discharged from the air blowing fan, wherein the vane is disposed in a portion where a portion of the flow of air having a relatively higher air flow rate has a relatively small area, while a portion of the flow of air having a relatively lower air flow rate has a relatively large area, in a cross-section of an outlet of the air blowing fan.
An electric range, comprising:
- a case;
- a cover plate coupled to an upper side of the case, 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, 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;
- 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;
- and
- a pair of vanes that divides and guides a flow of the air discharged from the air blowing fan and flowing toward the heat sink, wherein a distance between the pair of vanes increases toward the heat sink, and wherein the pair of vanes is disposed in a portion where a portion of the flow of air having a relatively higher air flow rate has a relatively small area, while a portion of the flow of air having a relatively lower air flow rate has a relatively large area, in a cross-section of the outlet of the air blowing fan.
An electric range, comprising:
- a case;
- a cover plate coupled to an upper side of the case, 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, 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;
- 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;
- and
- a pair of vanes that divides and guides a flow of the air discharged from the air blowing fan and flowing toward the heat sink, wherein a first vane of the pair of vanes extends at a first angle with respect to a lengthwise direction of the heat sink and a second vane of the pair of vanes extends at a second angle with respect to the lengthwise direction of the heat sink, wherein the second angle is greater than the first angle, and wherein the pair of vanes is disposed in a portion where a portion of the flow of air having a relatively higher air flow rate has a relatively small area, while a portion of the flow of air having a relatively lower air flow rate has a relatively large area, in a cross-section of the outlet of the air blowing fan.
