Abstract
The present invention offers an induction heating apparatus in which the infrared sensor performs stable temperature detection without undergoing the influence of leakage magnetic flux from the induction heating means. This induction heating apparatus has a main frame which forms an outer casing, a top plate provided on the upper side plane of the above-mentioned main frame and having at least one loading part on which a cooking container to be heated is placed, an induction heating means which is provided under the above-mentioned loading part and is to heat the above-mentioned cooking container to be heated, an infrared sensor which is provided in the neighborhood of the above-mentioned induction heating means and receives the infrared radiation radiated from the above-mentioned cooking container to be heated, and outputs the detected signal corresponding to the amount of the infrared radiation, a control board that detects the temperature of the above-mentioned cooking container to be heated based on the above-mentioned detected signal, and controls the output of the above-mentioned induction heating means, and a magneto-shielding member having a cylindrical body covering the pe…
