摘要： An induction heating device prevents an object to be heated from being displaced and buoyed from a mounting surface due to an mutual action of repulsive forces between the object to be heated and an induction heating coil. The induction heating device includes a source-current detector for detecting a source current input to a high-frequency inverter including the induction heating coil and an inverter circuit, a source-current change detector for measuring a change against time of a magnitude of the source current to detect a displacement and buoying of the object to be heated, such as a cooking pot, and a change examining unit. The controller controls an output of the high-frequency inverter in response to a detection result of the change examining unit. The induction heating device prevents the cooking pot from being displaced and buoyed even if the pot is not touched by a user at startup of heating or during the heating operation, and is inexpensive and safe.

摘要： In an induction heating apparatus, in order to decrease the buoyancy exerted on an object to be heated which is made of a material having high electrical conductivity and low magnetic permeability, such as aluminum, an electrical conductor is provided between a heating coil and the object to be heated, thereby increasing the equivalent series resistance of the heating coil. Hence, the current of the heating coil, which is required for obtaining a desired heating output, is decreased, whereby the buoyancy of the object to be heated can be decreased. In addition, the electrical conductor is divided into two halves, and they are arranged in a circular arc form with a clearance provided therebetween and made close contact with the bottom face of a plate, whereby the temperature rise of the electrical conductor can be restricted. Furthermore, the heat of the electrical conductor is transferred and dissipated to the object to be heated, whereby the heating coil and the like are not damaged even if the electrical conductor is heated. An electrical conductor temperature sensor for detecting the temperature of the electrical conductor is provided; when the detection temperature becomes a predetermined temperature, the heating output of a drive circuit is decreased, whereby the heat generation of the electrical conductor is decreased and the heating coil and the like are not damaged by heat.
摘要翻译：在感应加热装置中，为了降低由诸如铝的导电性高导磁率低的材料制成的被加热物体的浮力，在加热线圈和物体之间设置电导体被加热，从而增加加热线圈的等效串联电阻。因此，为了获得期望的加热输出而需要的加热线圈的电流减小，从而能够降低待加热物体的浮力。此外，电导体被分成两半，并且它们被布置成圆弧形，间隙设置在它们之间并且与板的底面紧密接触，由此可以限制电导体的温度升高。此外，电导体的热量被传递并散发到被加热物体，由此即使加热电导体，加热线圈等也不会损坏。提供用于检测电导体的温度的电导体温度传感器; 当检测温度变为预定温度时，驱动电路的加热输出减小，导电体的发热量减少，加热线圈等不会受到热损伤。
