Embodiment approach 1
[0032] (structure)
[0033] figure 1 It is a figure which shows the structure of the induction heating cooker of Embodiment 1.
[0034] in figure 1 Among them, 101 is a top plate, 102 is a main body housing, 103 is a circuit for supplying high-frequency current, 104 is an operation unit, 105 is a display unit, and 22 is a heating coil.
[0035] The top plate 101 is used for placing heated objects such as a pan, and is provided with a heating port 106 indicating the placing position of the pan. Inside the main body housing 102, the circuit 103, the display unit 105, and the heating coil 22 are housed, and the top plate 101 is covered on the upper surface thereof to house the internal structure of the main body housing 102.
[0036] Circuit 103 has the following figure 2 In the structure described in, a high-frequency current is supplied to the heating coil 22.
[0037] The operating unit 104 is used by the user to adjust the heating output.
[0038] The display unit 105 is a screen disp...
Embodiment approach 2
[0184] In the second embodiment, an aspect in which the inverter circuit 9 is configured by a half bridge will be described.
[0185] Figure 13 It is a figure which shows the circuit structure of the induction heating cooker of Embodiment 2.
[0186] Hereinafter, the description will be focused on differences from the first embodiment described above. In addition, in Figure 13 In the above-mentioned embodiment 1 ( figure 2 ) The same symbol is attached to the same structure.
[0187] Each inverter circuit 9'in the second embodiment has a half-bridge structure, and includes a high-potential side switching element (upper switch 12') and a low-potential side switching element (lower switch 13'), and an upper switch 12' The upper diode 14' connected in anti-parallel, and the lower diode 15' connected in anti-parallel with the lower switch 13'.
[0188] Between the output points in each inverter circuit 9', a load circuit 24' is connected. The load circuit 24' includes a heating coil ...

Abstract
During performance of heating operation for applying set power to a heating target, control means 25 controls an inverter circuit 9 to output power corresponding to the set power to a heating coil 22 above which a heating target is placed, on the basis of a determination result by load determining means 26. In the case where the heating target is not placed above the heating coil 22 to which the power corresponding to the set power is being output, the control means 25 controls the inverter circuit 9 to output a specific power that is smaller than or equal to the set power to the heating coil 22.
Description
Technical field [0001] The present invention relates to an induction heatingcooker provided with a plurality of heating coils. Background technique [0002] In conventional induction heating cookers, for example, the following induction heating cookers have been proposed: "It is equipped with a load detection unit that detects that the object to be heated is placed on the top plate, and the load detection unit detects for each heating coil An object to be heated is placed above the heating coil, and the circuit supplies a high-frequency current to only the heating coil on which the object to be heated is placed on the load detection unit detected" (for example, refer to Patent Document 1) . [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 2008-293871 (claim 2) Summary of the invention [0004] In the technique of Patent Document 1, it is possible to suppress the decrease in heating efficiency and increase in leakage flux due to the size and placement of the p...
