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.

Electric range

An electric range is provided that may include a dedicated coil temperature sensor configured to measure a temperature of a working coil so as to monitor the temperature of the working coil in real time and actively respond to a working coil load condition, thereby remarkably increasing an operation time of the electric range.

An electric range is provided that may include a lower casing defining a lower portion of a case that is formed in two steps. In particular, the lower casing may include a first lower part; a second lower part recessed from an inside of the first lower part, and to which a bracket is coupled; and a third lower part that protrudes from at least a predetermined area of a portion of the first lower part.

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 includes a heating part configured to heat an object based on an electromagnetic interaction. The heating part may include a core frame having a plurality of channels disposed radially on a lower surface thereof and a plurality of ferrite cores mounted onto the channels and disposed under the core frame. The core frame include a plurality of air gaps disposed between the plurality of channels. The plurality of air gaps are disposed radially, and the plurality of air gaps connect a center of the core frame and an edge of the core frame.

An electric range is provided. The electric range may include a case; at least one heating unit configured to heat an object; at least one drive circuit configured to drive the heating unit; at least one display configured to display visual information; at least one air blowing fan configured to output air; and at least one air guide configured to guide air output from the air blowing fan to the drive circuit. The air output from the air blowing fan may be supplied to a first end of the air guide, and a height of an upper surface of the first end of the air guide may be greater than a height of an upper surface of the air blowing fan. A first portion of the air output from the air blowing fan may be discharged through a gap between the upper surface of the first end of the air guide and the upper surface of the air blowing fan, and supplied to the display.

Electric range and air guide for electric range

An electric range is provided that may include an air guide provided with a first member that prevents air, output from an air blowing fan, from flowing into a space between a lower surface of a case and a drive circuit.

An electric range is provided that may include a case; at least one fan configured to cool an inside of the case; at least one first through hole formed on a lower surface of the case and configured to supply air to the at least one fan; and a first cover disposed to encircle the at least one first through hole outside of the lower surface of the case and having a plurality of first slits. The first cover may prevent a foreign substance from contacting the at least one fan. The foreign substance may be an end portion of a user's body, for example, a user's finger. The at least one fan may have no structure for preventing contact of a foreign substance.

An electric range includes a case and a cover plate coupled to an upper surface of the case to place an object. Further, the electric range includes a plurality of heating portions disposed below the cover plate to heat the object and an upper bracket disposed under the heating portion to support the heating portion a control board disposed between the cover plate and the upper bracket. Furthermore, the electric range includes a support member having a first end disposed under the control board and a second end disposed on the upper bracket to support the control board and a base bracket disposed under the upper bracket and comprising a printed circuit board.

An electric range in one embodiment includes a case and a cover plate coupled to an upper end of the case to allow an object to be heated to be placed on an upper surface thereof The electric range further includes a plurality of heating parts disposed under the cover plate and configured to heat the object to be heated, an upper bracket disposed under the heating part and configured to support the heating part, a base bracket disposed under the upper bracket to allow a printed circuit board to be mounted thereon, and a cover bracket disposed outside the upper bracket and the case coupled to the case and configured to support the cover plate.
