An induction hob device comprising at least one cooktop at least one first coil and at least one second coil which are displaced relative to each other at least in a direction perpendicular to the cooktop and with a control unit.

In order to improve an efficiency, it is proposed that the control unit is provided to at least temporarily operate the first coil and the second coil simultaneously.

A method is provided for identifying cookware items placed on top of an induction cooktop having a plurality of coils. The method includes the following steps: acquire coverage factor information for each coil and collect it into a matrix; identify all local maxima in the matrix; find the coordinates of each of the local maxima as follows: when the local maxima is a single coil, the coordinates are those of the coil center, and when the local maxima is a region of contiguous coils, the coordinates are those of a centroid of the region; calculate distances from each coil to each of the coordinates of the identified local maxima; determine a minimum among the distances; classify the coils in clusters, based on the distances from the local maxima; and use the identified coil clustering to estimate the position, shape, size, and orientation of the cookware items.

An induction hob device comprising at least one cooktop, at least one first inductor having at least one first coil portion and at least one further first coil portion, and at least one second inductor having at least one second coil portion.

In order to improve an efficiency, it is proposed that the second coil portion is at least partly located between the first coil portion and the further first coil portion.

The present invention relates to an induction cooking hob (10), in particular for a domestic appliance, comprising an optically transparent panel (12) for supporting cooking utensils, at least one illumination panel (14) arranged beneath the optically transparent panel (12), and at least one circuit board (18) arranged beneath the illumination panel (14), wherein said circuit board (18) includes a plurality of induction coils (16).

A hob apparatus includes a heating region for placement and heating of a cooking container. A dynamic display unit provides an identification of the heating region in an operating mode, and a control unit selects an identifying property of the identification of the heating region in the operating mode, depending on an operating parameter.

An illustrative induction warming range capable of heating one or more multiple-sized servers and/or pots at any location on the range top using a plurality of preconfigured heating settings including low (145-155 F), low-med (156-165 F), med-high (166-175 F), and high (176-185 F). The illustrative induction warming range may be configured for automatically switch off 2 minutes after pans are removed. The induction warming range is compatible with all induction ready servers and pans and may include a durable, easy to clean tempered glass top. The illustrative warming range may be configured as a portable unit for countertop use, as a built-in unit for installation in a countertop or other surface, and/or the unit may be configured for both countertop or drop-in use.

The invention discloses a hob (100) with free configurable heating array (115) and touchscreen control (130). A user may combine graphic representations (145) and (150) of a first and a second pot in order to combine a control operation of a first and a second heating zone (107, 112) associated to the respective pots. In this manner, plural heating zones can be combined by a single input, and visibility on the touchscreen control is improved by uniting both representations of the pots on the touchscreen control display. Combining/separating heating zones can be effected by the synchronous movement of two fingers uniting the two graphic representations of the pots on the touchscreen respectively diverging the two graphic representations of the pots on the touchscreen (130). A computer program product (500) allows to easily and freely configure the hob (100) and to perform maintenance and mass production.

Disclosed herein is a cooking apparatus. The cooking apparatus includes a cooking plate, a plurality of induction heating coils installed under the cooking plate, a plurality of drivers configured to supply driving power to the plurality of induction heating coils, and a controller configured to control the plurality of drivers to drive a plurality of groups to which the plurality of induction heating coils belong, respectively. Power output by a first driver, among the plurality of drivers, which drives a first group among the plurality of groups may be increased and power output by a second driver, among the plurality of drivers, which drives a second group among the plurality of groups may be decreased.

A device having: an article having a flat surface and a lower surface opposed to the flat surface; a cavity formed in the lower surface forming a complete loop surrounding a central portion of the article; a heating element having the same shape as the complete loop in the cavity and positioned to warm a portion of the flat surface adjacent to the heating element when the heating element is activated; a cooling device positioned to cool a portion of the flat surface in the central portion; and a release layer on the flat surface. A device having: an article having an upper surface; a heating element on the upper surface forming a complete loop surrounding a central portion of the article; and an electrically insulating material on the upper surface within the central portion.

Disclosed herein is a cooking appliance. A working coil is provided at a lower portion of the cooking appliance. The working coil heats a tray disposed in a cooking compartment in an IH mode. A receiver coil wirelessly receiving external power is stacked below the working coil. An electromagnetic shielding plate is installed between the working coil and the receiver coil to partition a space in which the two coils are installed. The electromagnetic shielding plate shields an electromagnetic field or electromagnetic waves such that the electromagnetic field or electromagnetic waves in one of the two partitioned spaces does not leak to the other space located across the electromagnetic shielding plate.
