Abstract: The present disclosure relates to an induction heating device. A loaded-object sensor according to the present disclosure is arranged concentrically and centrally in the working coil. Thus, the sensing coil and the working coil are adjacent to each other. When a current for the heating operation is applied to the working coil, an induction voltage is generated in the sensing coil by magnetic force generated by the current applied to the working coil. According to the present disclosure, a resistor circuit is used to reduce the induction voltage generated in the sensing coil when the heating operation of the working coil is performed.

Abstract: Proposed is a blender, in which a main body operates when a closure of the container lid on a container body is detected. In the blender according to the present disclosure, when the closure of the container lid is detected, a voltage of a preset signal pattern is applied to the first inductive coil of the main body, and the voltage is transferred to the second inductive coil of the container body by inductive coupling with the first inductive coil. The light emitting unit of the container body transmits a light signal to the light receiving unit of the main body by using the voltage transmitted to the second inductive coil, and the light signal has the signal pattern. When the light receiving unit receives the light signal of the signal pattern, the main body recognizes the closure of the container lid on the container body so that that the main body operates.

By using the voltage transferred to the second inductive coil, a light emitting unit of the container body transmits a light signal to a light receiving unit of the main body, and the light signal has a predetermined signal pattern. When the light receiving unit receives the light signal of the signal pattern, the main body recognizes the closure of the container lid on the container body such that the main body operates.

Abstract: Disclosed is an induction heating device. The disclosed induction heating device senses whether a container placed on a heating coil is off-center, and if so, the direction in which the container is off-center, on the basis of a change in the resonance current of a plurality of sensing coils disposed along the circumferential direction above the heating coil. Each of the plurality of sensing coils includes a plurality of first layer sensing coils and a plurality of second layer sensing coils. Each of the plurality of first layer sensing coils is electrically connected to a corresponding second layer sensing coil among the plurality of second layer sensing coils. The first layer sensing coil and the second layer sensing coil that are connected to each other are vertically misaligned and have opposite winding directions.
