| 1. A device for heating up meals, in which at least one functional tray is arranged within a housing which is closed by a
door and has a shielding effect for electromagnetic waves, where functional trays (2) each contain at least one induction coil (4) for producing an alternating electromagnetic field within which heating is achieved,
wherein an electrically conducting element (3) is located at least along an end face of at least one of the functional trays (2), which is oriented adjacent the door opening in the housing (1), and the at least one electrically conducting element (3) is respectively connected to at least one of a local potential, a housing potential and a ground potential and one of the
local potential, the housing potential and the ground potential being coupled to the electrically conductive element (3), when the at least one functional tray (2) is accommodated within the housing (1) and the door is in its closed position, so that the door forms a shield for electromagnetic waves and minimizes passage
of otherwise errant electromagnetic waves through the door.
