Power supply unit for supplying electricity to electrical appliance, has detection unit detecting presence of objects, which is different from secondary energy reception unit within transmission area

摘要

The supply unit has a primary energy transmission unit (28) with a transmission area (32) provided in wireless cooperation with a secondary energy reception unit (34) for supplying energy to an energy load (10) e.g. electrical pot. The secondary energy reception unit is arranged in the transmission area and is separable from the transmission area. A detection unit (38) detects the presence of objects, which is different from the secondary energy reception unit within the transmission area, where the detection unit has a circuit section.
