Japan, Feb. 24 -- SAMSUNG ELECTRONICS CO LTD has got intellectual property rights for 'INDUCTION HEATING DEVICE.' Other related details are as follows:
Application Number: JP,2021-199557
Category (FI): H05B6/06,386,H05B6/12,333
Stage: PROBLEM TO BE SOLVED: To enable the fire power of each object to be heated to be adjusted to desired magnitude even while eliminating noise to be generated in the case of simultaneously heating a plurality of objects to be heated.SOLUTION: An induction heating device includes at least two heating coils 1 for inductively heating an object to be heated, an inverter device 2 provided corresponding to the respective heating coils 1 to supply power to the corresponding heating coils, and control equipment 3 for controlling the inverter device 2. The control equipment 3 compares drive frequencies being frequencies of power to be supplied to at least two heating coils 1, changes the drive frequency of a higher frequency side coil 1 having a high drive frequency into a drive frequency of a lower frequency side coil 1 having a low drive frequency, controls the inverter device 2 corresponding to the lower frequency side coil 1 with a prescribed first control mode, and controls the inverter device 2 corresponding to the higher frequency side coil 1 with a second control mode different from the first control mode.SELECTED DRAWING: Figure 2 (Grant)
