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 limiting circuit is used to reduce the induction voltage generated in the sensing coil when the heating operation of the working coil is performed.

Abstract: A cooling apparatus is provided in which items to be cooled may be vertically stacked on each other in a state in which the items to be cooled are laid out or laid on their sides. When the items to be cooled are vertically stacked in the cooling apparatus, a problem in that an upper space of the cooling apparatus is not utilized may be solved to efficiently utilize an inside of a refrigerator or a back surface of a door. Also, a problem in that capacity within the refrigerator is reduced when the items to be cooled are horizontally received may be solved.
