Abstract
The apparatus consists of a refrigerator (10) into which it is possible to insert trays (27, 28, 29) on which various tableware containing different foods and/or drinks are placed. The refrigerator contains, in addition to the cooling unit (13), a high-frequency generator (17) which interacts with induction coils which are arranged in the trays, making it possible to heat suitable tableware inductively. Furthermore, a temperature monitoring means (19) is provided which switches the high-frequency generator off or on during a settable heating time and on reaching a predetermined temperature. A preferred embodiment of the temperature monitoring means contains an induction coil (41), which corresponds to the coils in the trays, and a metal element (42), the heat capacity of which approximately corresponds to that of a piece of tableware. The metal element is connected to the refrigerator housing by a heat-conducting connection (43, 44, 46). The heat conduction corresponds approximately to the heat absorption of the food in the tableware. A temperature sensor (47) which switches the high-frequency generator off or on at the settable temperature is arranged on the metal element. The app…
