AN APPARATUS FOR HEATING OF VESSELS FOR PREPARATION OF FOOD |
摘要 |
Cooking ranges using heating by eddy currents caused by induction of high frequency energy are known, but they have losses caused by leakage fields. The invention provides heating unit in which the magnet coils are integrated into magnetic circuit where the field is collected due to the disposition of the core. A preferred embodiment utilizes magnetic concrete for core parts with chambers for the coils. There may advantageously be cast a covering layer which is thin and wear resistant but still strong, because it is everywhere supported by the material.
