摘要： According to the present invention, there is provided an air-frying cooker (1) comprising: a cooking chamber (20); a food receiving container (5) in the cooking chamber (20) having a permeable bottom wall (9); a heater (19) for heating air in the cooking chamber (20); a fan (18) for circulating a flow of hot air in the cooking chamber (20) to cook the food; and a system (13) to maintain a predetermined level (LI) of water in the cooking chamber (20) during cooking. The predetermined level (LI) is disposed between a base (11) of the cooking chamber (20) and the bottom wall (9) of the food container (5).

摘要： The present invention relates to a system SY for determining a position of an RF transponder circuit RTC respective an ultrasound emitter unit UEU. The RF transponder circuit RTC emits RF signals that are modulated based on received ultrasound signals that are emitted or reflected by the ultrasound emitter unit UEU. The position of the RF transponder circuit RTC respective the ultrasound emitter unit UEU is determined based on a time difference ΔT1 between the emission of an ultrasound signal by the ultrasound emitter unit UEU and the detection by the RF detector unit RFD of a corresponding modulation in the RF signal emitted or reflected by the RF transponder circuit (RTC).
