1. A cooking appliance comprising:
a cooking chamber configured to cook food therein and openable in a first direction;
a shelf provided to be inserted into the cooking chamber in the first direction and having a cooking surface on which food is placed;
a heater disposed on an upper surface of the cooking chamber, the heater configured to supply radiant heat to the cooking surface; and
a magnetron configured to generate high frequency waves to be supplied to the shelf through a lower surface of the cooking chamber,
wherein:
the shelf includes a heat generating member configured to generate heat by the heat generating member absorbing the high frequency waves generated by the magnetron and disposed below the cooking surface so that the heat generated by the heat generating member is conducted to the cooking surface,
the cooking surface includes a first area arranged at one side in a second direction perpendicular to the first direction with respect to a center line of the cooking chamber and a second area arranged at an opposite side in the second direction with respect to the center line of the cooking chamber,
the heat generating member includes a ferrite material, a first heat generating portion disposed below the first area and having a rectangular shape to correspond to the first area and configured to supply heat to the first area, and a second heat generating portion disposed below the second area and having a rectangular shape to correspond to the second area,
the first heat generating portion includes the ferrite material in a content larger than a content of the ferrite material included in the second heat generating portion,
the first heat generating portion supplies more heat to the first area than the second heat generating portion supplies to the second area,
the magnetron is disposed at a lower side of the cooking chamber in a third direction perpendicular to the first and second directions and faces the first heat generating portion and the second heat generating portion,
the heater includes a first heater disposed above the first area to provide radiant heat to the first area and a second heater disposed above the second area to provide radiant heat to the second area,
a temperature of heat provided to the first area by the first heater and the first heat generating portion is different from a temperature of heat provided to the second area by the second heater and the second heat generating portion,
a temperature of heat supplied from the first heater is provided to be approximately equal to a temperature of heat emitted from the first heat generating portion,
a temperature of heat supplied from the second heater is provided to be approximately equal to a temperature of heat emitted from the second heat generating portion, and
the shelf further includes a depression formed between the first area and the second area along the center line so that the first area and the second area are divided.
