Abstract
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.
Claims20
An electric range, comprising:
- 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, wherein the air guide comprises:
- a first area that communicates with the air blowing fan and guides air to flow;
- a second area that guides the air to be discharged outward;
- and
- a changing area that connects the first area and the second area and changes a flow direction of air having passed through the first area to the second area, and wherein the cross-sectional area of the air guide increases gradually from the first area to the changing area, and the second area.
6 more elements
An electric range, comprising:
- a case;
- at least one heater disposed in the case and configured to heat an object to be heated;
- a base bracket disposed under the at least one heater and on which a printed circuit board is mounted;
- a heat sink mounted on the printed circuit board;
- an air blowing fan mounted on the base bracket and 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 comprises:
- a first area that communicates with the air blowing fan and guides air to allow the air to flow in a lateral direction of the base bracket;
- a second area that is bent in an upward-downward direction of the base bracket and guides air to allow the air to be discharged outward;
- and
- a changing area that connects the first area and the second area and changes a flow direction of air having passed through the first area to the second area, and wherein the cross-sectional area of the air guide increases gradually from the first area to the changing area, and the second area.
8 more elements
An electric range, comprising:
- 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;
- at least one heater including a working coil disposed under the cover plate and configured to heat the object to be heated;
- an upper bracket disposed under the at least one heater and configured to support 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 mounted on the base bracket and 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 comprises:
- a first area that communicates with the air blowing fan and guides air to allow the air to flow in a lateral direction of the base bracket;
- a second area that is bent in an upward-downward direction of the base bracket and guides air to allow the air to be discharged outward;
- a third area that extends from the first area and changes a flow direction of air having passed through the first area;
- and
- a fourth area that extends from the third area, communicates with the second area, and changes a flow direction of air having passed through the third area, and wherein the cross-sectional area of the air guide increases gradually from the first area to the third area, the fourth area, and the second area.
