Cooking apparatus using induction heating

A cooking apparatus using induction heating comprising:

• a top plate including a heating zone on which a cooking container is placed;
• a working coil located below the heating zone;
• an inverter which has a plurality of switching elements, and supplies current to the working coil through an operation of the plurality of switching elements;
• a first sensor which acquires vibration data in an audible frequency band;
• and
• a controller which first determines a temperature range of contents contained in the cooking container, based on the vibration data acquired from the first sensor, secondly determines whether the temperature range, based on power amount data of the working coil, and determines the temperature range, based on a result of the first determination and a result of the second determination.

• a first sensor which acquires vibration data in an audible frequency band;
• and
• a controller which calculates a probability for each temperature class, based on the vibration data acquired from the first sensor, and calculates a final probability for each temperature class by reflecting a transition probability corresponding to each probability for each temperature class as a weight.
