Cooking appliance

A cooking appliance comprising:

• a casing having a cavity therein, of which a front surface of the casing has an air inlet part and an air outlet part at different heights;
• a door provided at the casing to open and close the cavity;
• a plurality of heat sources arranged at the casing, including a second heat source arranged at an upper portion of the casing;
• and
• a plurality of cooling fans arranged at a first electric chamber of the casing, to suction external air through the air inlet part,
• wherein the first electric chamber is provided behind the air inlet part, the plurality of cooling fans to transfer the suctioned air to a second electric chamber provided behind the air outlet part,
• the plurality of heat sources are arranged at different electric chambers, respectively, and
• wherein the second heat source comprises:
• a fixed assembly fixed to the casing;
• and
• a moving assembly comprising a heater, the moving assembly movable relative to the fixed assembly to change a distance between a bottom surface of the cavity and the moving assembly,
• wherein an air flow path from the air inlet part is provided between a heater housing of the moving assembly and an outer casing of the casing, and at least one cooling fan is arranged at the air flow path.

• a door provided at the casing to open and close the cavity;
• a first heat source arranged at a first side surface of the casing, to emit microwaves toward the cavity;
• a second heat source arranged at a bottom surface of the casing, to emit magnetic fields toward the cavity;
• a third heat source arranged at an upper portion of the casing, the third heat source being movable toward a bottom surface of the cavity, to emit radiant heat toward the cavity;
• a controller arranged at a second side surface opposite to the first side surface of the casing with the first heat source;
• a power supply arranged at a rear surface of the casing;
• and
• a plurality of cooling fans arranged at a first electric chamber provided behind the air inlet part, to discharge air to the controller and the power supply;
• and
• wherein the third heat source comprises:
• a fixed assembly fixed to the casing;
