Abstract: A refrigerator includes: a cabinet; a door rotatably connected to the cabinet by a hinge; and a door opening device for opening the door. The door opening device includes a driving motor and a push member configured to move in the forward/backward direction. The push member includes a first end portion positioned close to the front surface of the cabinet and a second end portion positioned on the opposite side of the first end portion. The cabinet includes a cabinet side wall positioned close to the hinge. The door includes a door side wall positioned close to the hinge. When the door is closed, the horizontal distance between the first end portion and the cabinet side wall or the door side wall is smaller than the horizontal distance between the second end portion and the cabinet side wall or the door side wall.

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.
