Total Claims: 5
Claim 1
Independent Claim
234 words
Apparatus for cooling, storing and reheating complete meals, which are prepared so that they are ready to eat, introduced in portions into appropriate tableware for eating and drinking and arranged on a tray, comprising a refrigerator which, in addition to a cooling unit for the refrigerator , is equipped with a generator for inductively transmittable electrical energy, and trays, each of which has at least one induction coil which is operatively coupled to the generator when the tray is placed in the refrigerator, and tableware components which have a metal layer at least on the outer surface of the base, the said metal layer being suitable for inductive heating by said induction coils, a temperature monitoring means (19), wherein the temperature monitoring means contains an induction (41) fixed in the refrigerator apart from said trays and a workpiece (42) adjacent to said induction coil (41) disposed for inductive heating thereby the heat capacity of said workpiece being virtually equivalent to that of a full plate of tableware and said workpiece having a temperature measuring means (47) mounted thereon for controlling a switch for the supply voltage to the generator (17), said temperature monitoring means switching the generator (17) off or on during the heating time responsive to the temperature measuring means (47) exceeding a predetermined temperature or falling below it thereby simulating the temperature of the tableware in the region of the metal layer.

Claim 3
Dependent Claim
30 words
Apparatus according to claim 1, characterized in that the workpiece (42) is fastened to the refrigerator by means of a device (43, 44, 46) having means for adjustable heat conduction.
Claim 4
Dependent Claim
68 words
Apparatus according to claim 1, characterized in that the workpiece is a metal disc (42) having a sleeve (43) which is arranged in the centre of the surface which faces away from the induction coil, which sleeve, in order to adjust the heat conduction, can be pushed to different extents onto a bolt (44) which is fastened to the refrigerator and made of material having good thermal conductivity.
Claim 5
Dependent Claim
68 words
