Abstract: The invention relates to a device for heating up meals. It comprises a housing which can be closed by means of a door and shields the surroundings from electromagnetic waves. One or more functional trays which contain one or more induction coils are held within the housing, in order to be able to inductively heat up meals held in containers so that they can be consumed. The object of the invention is to increase the operational reliability of a device of this type. According to the invention, an electrically conducting element is therefore present on end faces of functional trays which are oriented in the direction of a door opening in the housing. Each individual electrically conducting element is also connected to the local potential, housing potential and/or ground potential, in order to be able to ensure that the surroundings are shielded from electromagnetic waves, even when the housing door is open.
