PROBLEM TO BE SOLVED: To provide an electromagnetic induction heating cooker performing ultrasonic vibration without using an ultrasonic vibrator, accelerating the water absorption of food inside a container, facilitating the washing of the container or the like and cooking tasty food. SOLUTION: In a cooking process in which there is sufficient water 10 in a container 3, when a high frequency current flows to an electromagnetic induction coil 5, an alternating magnetic field is generated on the basis of the direction of the current flowing to the electromagnetic induction coil 5 and the container 3 facing the electromagnetic induction coil 5 is extruded by the same frequency as the high frequency waves of the alternating magnetic field to the inner side direction of the container 3 by the high frequency waves. The high frequency waves of the alternating magnetic field are reflected by a magnetic flux modulation plate 6 and the surface of the container 3 facing the magnetic flux modulation plate 6 is extruded by the same frequency as the high frequency waves to the outer side direction of the container 3. When the frequency of the high frequency waves resonates with the intrinsic vibration frequency of the container 3, by the repetition of the extrusion of the container 3 in the inner and outer side directions, ultrasonic waves are generated in the water 10 inside the container 3. |
