7 . The electric range of claim 6 , wherein the upper wall is bent downward in the second area such that the air guide guides air discharged from the second area to a lower portion of the case.
8 . The electric range of claim 5 , wherein the base bracket comprises:
a first vent formed in a portion corresponding to the air blowing fan; and
a second vent formed in a portion corresponding to the fourth area.
9 . The electric range of claim 2 , wherein a lengthwise direction of the heat sink extends in parallel with a direction in which air passes through the air guide.
10 . The electric range of claim 9 , wherein the heat sink comprises a plurality of cooling fins that protrudes downward from a lower surface thereof and extends in a direction parallel with the lengthwise direction of the heat sink.
11 . The electric range of claim 10 , wherein the heat sink is provided with a flow channel that passes through the heat sink in the lengthwise direction of the heat sink and forms a flow path of air.
12 . The electric range of claim 11 , wherein the heat sink comprises:
a slanted portion disposed on both sides of the heat sink and having a slanted upper surface; and
a plane portion formed at a center of the heat sink, having the flow channel formed therein, and having a flat upper surface.
13 . The electric range of claim 12 , wherein the vane protrudes upward from the base bracket.
14 . The electric range of claim 13 , wherein the vane is disposed between the air blowing fan and the air guide.
15 . The electric range of claim 12 , wherein the vane is integrated with the air guide at an inlet of the air guide, or with the air blowing fan at the outlet of the air blowing fan.
16 . 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.
