An induction cooktop device includes a cooktop plane and an induction heating unit that includes an induction heating element, with the induction heating element extending at least in a subarea along a first principal plane of orientation which deviates from the cooktop plane. The induction heating element includes a first section extending at least essentially within a second principal plane of orientation, and a second section extending at least essentially within a third principal plane of orientation which differs from the second principal plane of orientation.

An induction heating device includes a case, a working coil, a cover plate, a luminous element, a light guide disposed around the working coil, an input interface that is flush with an upper surface of the cover plate, a first controller configured to control driving of the working coil and the luminous element and to detect a position of one or more objects disposed on the upper surface and an arrangement sequence of the one or more objects placed on the upper surface, and a second controller configured to receive, from the first controller, information on the position and the arrangement sequence of the one or more objects, and control the input interface to display an image corresponding to a heating zone for the one or more objects based on the information on the position and the arrangement sequence of the one or more objects.

The present invention relates to an induction cooking hob (10) including a number of induction coils (12). Said induction coils (12) are arranged on the induction cooking hob (10) according to a predetermined scheme. At least a portion of the induction cooking hob (10) is covered by the induction coils (12). At least one heating area is formed on the induction cooking hob (10) by activating a single induction coil (12) or a combination of adjacent induction coils (12). At least a portion of the induction hob (12) includes induction coils (12) shaped as triangular discs.

An induction hob including at least one switching element and at least one induction coil is provided. The switching element provides an alternating current flow through the induction coil. Cooling means provide airflow through the induction hob for cooling the switching element and the induction coil. The induction coil is arranged at a first side of a first plate-shaped support element and the switching element is arranged at a first side of a second plate-shaped support element. The first support element and the second support element are connected to one another and are arranged at a distance in order to form an air channel therebetween. The cooling means are arranged such that airflow is provided through the air channel.

A heating device for a hob has a flat rectangular carrier with an outer edge, two heating elements which each have a heating conductor and which together form a heating area and which are fastened on the carrier, wherein each heating element defines a partial heating area, and the partial heating areas are situated inside the rectangular shape of the carrier. The heating elements and their partial heating areas can be operated independently of one another. The partial heating areas of the heating elements do not intersect. A first partial heating area is rectangular and extends, by way of at least one of its outer sides, to the outer edge of the carrier and runs parallel in relation to the outer edge. A second partial heating area covers the portion of the rest of the carrier which is left free by the first partial heating area. Various configurations of heated areas can be achieved owing to the independent operation.

A smart table is disclosed. The smart table includes a plate, an inverter configured to convert direct current (DC) power into alternative current (AC) power and to supply the AC power, a coil unit disposed below the plate and including a plurality of working coils heated by the AC power, a radio frequency identification (RFID) reader configured to recognize an RFID tag of a home appliance placed on the plate and to receive information on the home appliance from the RFID tag, and a processor configured to drive one or more of the plurality of working coils as wireless power transmission coils to perform control to transmit wireless power to the home appliance based on the received information.

In a method for a cooktop, in particular for producing and/or operating the cooktop, which has at least one variable cooking surface, the cooking surface is partitioned in an operating mode along a partitioning direction into a plurality of heating zones to which at least one heating parameter is assigned in each case in a location-dependent manner in order to heat a cooking utensil that is deposited on the heating zone. In order to ensure flexible production and/or flexible operation of the cooktop, during partitioning of the cooking surface into the heating zones in at least one peripheral region of the cooking surface, at least one cooking utensil characteristic is taken into account.

A method is provided for controlling average power delivered to coils of a flexible induction cooktop having a plurality of coils that are arranged adjacent to one another in a non-overlapping manner to form an array. The method includes: a) identifying a group of the plurality of coils that are underlying one or more cookware items; b) providing power to at least one coil of the group of coils underlying one or more cookware items; and c) at the same time, not providing power to coils of the group of coils underlying the cookware items that are adjacent to the at least one coil to which power is provided to prevent interaction between adjacent coils of the group of coils.

A cooking appliance includes a top plate portion configured to support an object to be heated; an intermediate heating body configured to transfer heat to the object; and a plurality of working coils configured to generate a magnetic field to heat at least a portion of the object to be heated and the intermediate heating body. Also, the intermediate heating body includes one or more heating areas corresponding to one or more working coils among the plurality of working coils.

A method for controlling an induction cooking hob with a pot detection system and a user interface. The method includes the steps of activating the induction cooking hob by touching a main switch by a user; starting automatically the pot detection system by a control unit of the induction cooking hob; and detecting at least one pot and/or pan on a cooking surface of the cooking hob or detecting if no pot or pan is placed on said cooking surface, by the pot detection system; deactivating the pot detection system after a predetermined time interval if no pot or pan or if no further pot or pan, respectively, has been detected on the cooking surface within the time interval; activating a deactivation indicator showing to the user that the pot detection system is deactivated, and providing an opportunity to reactivate the pot detection system by the user.
