Abstract: A household appliance system includes a household appliance having a first induction unit configured to inductively supply energy, a household unit having a second induction unit configured to inductively receive the energy that is supplied from the first induction unit, and a safety unit configured to prevent, as a function of a safety parameter, at least in an interval a transmission of energy to the second induction unit.

Abstract: A cooking system includes a set-down plate for setting down cookware, and a detection unit designed to detect the cookware. The detection unit includes a radiation source for emitting electromagnetic radiation and a radiation detector for receiving electromagnetic radiation. A first radiation guiding element transmits the electromagnetic radiation from the radiation source to a set-down region of the set-down plate, and a second radiation guiding element transmits electromagnetic radiation reflected from the cookware to the radiation detector.

Abstract: A cooking system includes a placement plate, and a radiation guiding element which is permeable for infrared radiation and visible light. The radiation guiding element extends in an assembled state at least in part along a normal direction perpendicular to a main extent plane of the placement plate from an upper side to a lower side of the placement plate.

Abstract: A cooktop accessory device includes a detection coil configured to detect an inductive signal of an induction heating unit, and a signal analysis unit configured to determine a parameter of the inductive signal.

Abstract: A food preparation apparatus, in particular a cooktop apparatus, having a sensor unit which is provided in order to receive image data of a preparation region, having an additional sensor unit which is provided in order to receive additional image data of the preparation region and having a control unit for analyzing the image data. In order to increase user convenience and to achieve precise replication of a food preparation process, according to the invention the control unit is provided in order to also analyze, in at least one operating state, in addition to the image data formed as 3D image data, the additional image data in order to generate a digital twin of a situation in the preparation region, in particular of a food preparation process in the preparation region.

Abstract: An underlay apparatus for use with a hob includes an underlay unit positioned between a cooking vessel and a cooking zone of the hob, and a positioning aid supporting the positioning of the underlay unit relative to the cooking zone.

Abstract: A hob apparatus includes a hob plate having a cooking region, a light source unit including a light source for providing light, and a fiber optic unit including an optical fiber for transmitting the light into at least one region that surrounds the cooking region. The optical fiber includes an end region which contacts the hob plate.

Abstract: An induction energy transmission system includes a supply unit having a supply induction element to inductively provide energy in an operating state. A receiving unit receives at least part of the energy provided by the supply induction element in the operating state. A sensor unit detects a measurement variable and a first information channel transmits a first signal between the receiving unit and the supply unit, with the first signal coding the measurement variable. A second information channel which differs from the first information channel transmits a second signal between the receiving unit and the supply unit, with the second signal coding the measurement variable.

Abstract: A household appliance system includes a household appliance, an external unit for operating the household appliance, and a control unit designed to perform a characterization process and to enable operation of the household appliance by the external unit, when the characterization process has been completed.

Abstract: A household appliance system includes a household appliance, an external unit for operating the household appliance, and a control unit designed to automatically check in one operating mode at least in intervals as to whether the external unit is arranged in an operating range and in the event that the external unit is arranged within the operating range to enable operation of the household appliance by the external unit.

Abstract: An induction energy transmission system includes a receiving unit having a first receiving induction element for receiving an inductively provided energy, and a voltage converter unit connected to the first receiving induction element and configured to convert an electrical voltage of the first receiving induction element for supply of energy to an additional unit.

Abstract: An induction device includes an induction unit including a sensor unit which is arranged above the induction unit in a mounted position and includes a plurality of temperature sensor elements arranged in a distributed manner and configured to detect a sensor parameter in the form of a temperature parameter of a unit. A control unit is provided to analyze the sensor parameter.

Abstract: An induction device includes an induction unit including a sensor unit, which is arranged above the induction unit in a mounted position and includes a plurality of presence sensor elements arranged in a distributed manner and configured to detect a sensor parameter in the form of a presence parameter of an object.
