Wireless induction heating cooker with improved heat conduction efficiency

A wireless induction heating cooker comprising:

• a main body configured to receive and heat food objects therein;
• a lid configured to couple to an upper surface of the main body;
• and
• an inner pot configured to be accommodated in the main body and to be heated based on a magnetic field being generated by a heating coil of an induction heating device,
• wherein the inner pot defines a heat conduction space that is surrounded by a bottom surface, an outer surface, and an inner surface of the inner pot,
• wherein the inner pot has (i) a first part that extends downward to a preset depth and defines a first inner diameter that is constant and (ii) a second part that extends downward from the preset depth toward the bottom surface of the inner pot and defines a second inner diameter that decreases as a depth of the inner pot increases toward the bottom surface of the inner pot, and
• wherein an outer diameter of the inner pot is constant at the first and second parts of the inner pot.
